Frequently Asked Questions - XG E MINOLTA

How do I set the film speed (ISO) on the Minolta XG-E?

Lift the shutter speed dial and turn it until the desired ISO value (25–1600) aligns with the index. The dial clicks into place when released.

How do I use exposure compensation?

Press the auto-lock button (near the shutter dial) and turn the dial away from 'A' to the desired compensation value (±2 EV in 1/2 steps). The setting is visible on the dial scale.

What batteries does the XG-E use and how do I check them?

Two silver-oxide 1.5V cells (S-76 or G-13). Set the mode switch to B.C. and press the shutter button; a red LED at the front lights if voltage is sufficient (>2.0V).

How does the self-timer operate?

Set the mode switch to SELF, press the shutter button. A front LED blinks for about 10 seconds; the blinking accelerates in the last 2.5 seconds before the shutter fires.

Can I use a flash with the XG-E?

Yes. Mount any flash with a hot shoe or PC cord. For Minolta Auto Electroflash 200X, when charged, the viewfinder shows a blinking '60' and the shutter automatically sets to 1/60 sec sync speed.

How do I rewind the film?

Press the rewind button on the bottom, lift the rewind knob, and turn it clockwise until the film is fully rewound. The back cover unlocks automatically when the rewinding starts.

What is the meaning of the viewfinder LEDs?

In auto mode, LEDs show the selected shutter speed; two adjacent LEDs indicate an intermediate speed. A blinking '60' signals flash-ready. The topmost LED (1000) blinks if the scene is too bright (over-range).

Why won't the shutter release?

Possible causes: batteries dead (check with B.C.), over-range lock active (too bright), or film not advanced after last shot. Ensure the shutter speed dial is not at 'B' and the mode switch is not OFF.

Can I use an auto winder?

Yes, the Minolta Auto Winder G attaches to the bottom. It advances film after each shot. The camera automatically controls the winder via a signal pin.

How do I clean the camera?

Use a soft cloth slightly dampened with alcohol or flonsolve. Never use thinners, ketones, or ether. Keep the mirror and lens clean with a blower brush. Do not lubricate internally.

3. Shutter Dial Mechanism

The shutter speed dial of XG is provided with Auto/Manual changeover, film sens. setting, exposure correction and release switch mechanisms.

〈Operation〉

1. Shutter speed dial (0290) is usually engaged with dial shaft (0272), ASA brush holder (0273), and ASA dial plate (2005) respectively at aa', bb' and cc'. The dial then rotates along with each of the parts.
2. Further, dial shaft (0272) is engaged with shutter speed dial plate (0295) and cam plate (2009) respectively at dd' and ee', and then rotates along with shutter dial (0290).
3. With shutter speed dial (0290) lifted up, it is only disengaged from dial shaft (0272) at aa', and ASA brush holder (0273) and ASA dial plate (2005) rotate along with the shutter speed dial, but dial shaft (0272), shutter speed dial plate (0295) and cam plate (2009) do not rotate.

A. Auto/Manual/Bulb changeover

1. When shutter speed dial (0290) is set to Auto "A", cam plate (2009) being engaged with dial shaft (0272) at ee' rotates, then AM change lever (2010) operates at cam face ① in the direction of the arrow and AM change switch (S 8. S 10) of AM change holder is shifted to AUTO side of circuit board A (4201), simultaneously ⑧ of dial shaft (0272) is locked by ⑨ of auto lock plate (2016).

1. When auto lock plate (2016) is released from dial shaft (0272) by pressing auto lock button (2018) in the direction of the arrow, thus setting shutter speed dial (0290) to an optional position, cam face (f) of cam plate (2009) being engaged with dial shaft (0272) is also moved, and AM change lever (2010) is operated by the function of AM change spring (2012) in the opposite direction to the arrow and AM change switch (S 8 S 10) is then shifted to the manual side of circuit board (4201).

2. When shutter speed dial (0290) is set to "B" position, B switch contact (4237) is pushed by projection of cam plate (2009) in the direction of the arrow, and then valve switch (S5) including release switch C (4005) is turned OFF.

B. Film sensitivity setting

1. Film sensitivity can be set by lifting and turning shutter speed dial (0290) and setting it to the ASA sensitivity.

2. When shutter speed dial (0290) is lifted up, it is disengaged from dial shaft (0272) at as'. Then dial shaft (0272) is not rotated but ASA dial plate (2005) and ASA brush holder (0273) rotated.

And the ASA brush of ASA brush holder (0273) is set to the position on the sliding resistance of circuit board A (4201) corresponding to the sensitivity value of ASA dial plate (0295).

C. Exposure correction

1. Dial shaft (0272) is provided every 0.5 EV with click grooves up to ±2.0 EV from AUTO "A" position of shutter speed dial/Function selector. Exposure correction can be done by releasing auto lock plate (2016) and by setting "A" of shutter speed dial/Function selector (0290) to the desired position. At that time, cam plate (2009) is also rotated, but AM change lever (2010) is on cam face f, and AM change switch (S8, S10) of AM change holder (0271) is on the AUTO side.

2. In accordance with the exposure correction setting, the ASA brush of ASA brush holder (0271) moves on the ASA resistance of circuit board A (4201), then auto exposure and shutter speed indications are changed corresponding to the amount of correction.

D. Release switch

1. Shutter release button set (0281) passes through the center of shutter speed dial. Shutter button shaft (2021) comes in contact with release switch A (4003), and is maintained by shutter button holder (2020).
2. Shutter button shaft (2020) is separated from shutter button cap (2023) by the insulator of shutter button (2019), thus forming touch switch (S 11).
3. Release switch A (4003), B (4004), C (4005) and D (4006) are secured on shutter speed dial base plate (0384). Metering switch (S1) is formed by release switch A (4003) and B (4004); and release switch (S2) is formed by release switch C (4005) and D (4006). When shutter button set (0281) is pressed, these switches are turned ON in order, thus starting the operation of the circuit.

4. Magnetic Release Mechanism

1. Winding operation causes charge operation plate (0360) and charge lever (3010) being engaged with the plate to be shifted in the direction of the arrow.
2. Further, mirror return lever (0524) being engaged with charge lever (3010) is moved in the direction of arrow to push spring lever (0581) in the direction of arrow, thus charging operation lever spring B (2039) and completing the preparations for release.

〈Operation〉

1. Release magnet operation plate (2030) is maintained being attracted by release magnet (2028) via release magnet york (2026) and release magnet retainer (2027).
2. When shutter release button set (0281) is pushed, the electric circuit operates. Then a magnetic field opposite to that of release magnet (2028) is generated at release magnet bobbin (0583) attached to release magnet york (2026), and current instantaneously flows due to the discharge of condenser.
3. Consequently, release magnet operation plate (2030) becomes unbalanced in attraction, then released by the function of operation lever spring (2039) and shifted in the direction of arrow.
4. Release operation lever A (2036), B (2037), C (0571) and mirror release bar (5021) are operated in order via ⑧ of release magnet operation lever (0582), then mirror release bar (5021) pushes mirror release lever (5022) in the direction of arrow thus release the mirror system and allowing the mirror preset system to operate.

〈Return〉

1. When mirror return lever (0524) has returned to the original position with exposure completed, spring lever (0581) retained by mirror return lever (0524) becomes free.
2. On returning of mirror return lever (0524), charge lever (3010) and release operation lever spring (2035) also return in the direction of dashed line.
3. Release operation lever spring (2035) pushes release operation lever-A (2036) and operates release magnet operation lever (0582) in the direction of arrow, then presses release magnet operation plate (2030) against release magnet york (2026).
4. Operation of release operation lever-A (2036) in the direction of dashed line causes release operation lever-B (2037), C (0571), mirror release bar (5021) and mirror release lever (5022) to return in the direction of dashed line, thus getting ready for the next charge.

Magnetic Release Operation by Remote Cord

When the remote cord is connected to the release terminal as illustrated, the release core is electrically connected to the remote control contact B, and then release switch (S₂) and remote cord switch (S₂') are connected in parallel to each other. The magnetic release is operated when remote cord switch (S₂') is turned ON.

The shutter speed indication can be checked by setting touch switch (S 11 ) or metering switch (S 1 ) to ON.

5. Shutter Mechanism

1. The shutter of XG employs only electric control for the shutter speed control and only "X" for the synchro mechanism, thus making its mechanism very compact.
2. The shutter curtain runs laterally and the curtain shaft employs a single shaft system. Also, an OFF-type trigger contact is used and all parts are set up into one unit.

A. Charge mechanism

1. Winding operation causes charge gear A (2105) being engaged with shutter charge gear C (3016) on body side to rotate in the direction of arrow.
2. As charge gear B (2104) being engaged with charge gear A (2015) rotates, first curtain shutter gear (2106) and second curtain shutter gear (2107) rotate in the direction of arrow.
3. First curtain gear (2135) and second curtain gear (2129) being engaged with first curtain shutter gear (2106) and second curtain shutter gear (2107) rotate in the direction of arrow, charging the 1st and 2nd curtains.
4. Oo the other hand, control cam (2108) is rotated for charge during rotation of charge gear A (2105) in the direction of arrow.
5. Operation of control cam (2108) in the direction of arrow causes first curtain stop lever (0212) to be released so that the stop lever can rotate by its spring strength in the direction of arrow to stop the first curtain shutter gear.
6. Further, control cam (2108) operates trigger contact operation lever (2173) in the direction of arrow to turn on trigger contact (2166) and operate second curtain release lever (0255) in the direction of arrow to press shutter magnet (2150) against shutter magnet core (2149).
7. Operation of second curtain release lever (0255) in the direction of arrow causes second curtain lever (2160) and second curtain stop lever (0219) to be operated in the direction of arrow by second curtain lever spring (2163) and second curtain stop lever spring (2123). Then second curtain stop lever (0219) is able to stop second curtain barrel.
8. First curtain shutter gear (2106) is stopped by first curtain stop lever (0212), control cam (2108) by control cam stop lever (2115) and second curtain barrel (2129) by second curtain stop lever (0219). Shutter magnet core (2149) is pressed against shutter magnet (2150) and then trigger contact (2166) is ON thus completing the charge.
9. When the winding lever has returned to the original position, charge gear A (2105) and B (2104) also return to the pre-charge positions, thus completing the preparations for release.

B. Release mechanism

1. When the shutter button is operated, the preset interlocking lever on the mirror box side operates control cam stop lever (2115) in the direction of dashed line just before the end of operation of the mirror preset system, thus releasing control cam (2108).
2. Control cam (2108) is rotated in the direction of dashed line by the function of spring to operate first curtain stop lever (0212) in the direction of dashed line thus releasing it from first curtain shutter gear (2106), then it is rotated in the direction of dashed line by the function of the first curtain spring, allowing the first curtain to start running and exposure.
3. Oo completion of counting at the electric circuit, the current to the magnet is cut off. Shutter magnet core (2149) is released from shutter magnet, and magnet lever (0252) is operated in the direction of dashed line by the function of spring. Then second curtain release lever (0255), second curtain lever (2130) and second curtain stop lever (0219) are operated in the direction of dashed line in order, allowing the second curtain to start running to complete exposure.

C. X contact mechanism

1. When first curtain shutter gear (2106) is rotated in the direction of arrow, first curtain brake lever (0258) having been pushed up at ⓐ is operated in the direction of arrow by spring, then X contact plate (0207) completes the preparation for operation.
2. On the other hand, operation of charge lever (3010) on body side in the direction of arrow causes X lever (0205) having been pushed at © to be operated in the direction of arrow by spring, then X contact (2188) also completes the preparation for operation.

〈Operation〉

1. As the first curtain runs, first curtain shutter gear (2106) rotates in the direction of arrow and pushes first curtain brake lever (0258) at ④ of first curtain shutter gear (2106) just before the end of rotation (just before completion of 1st curtain running).
2. First curtain brake lever (0258) pushes X contact plate (0207) at ⑥ in the direction of arrow, then X contact (2188) and X contact plate (0207) are ON.
3. When the mirror return lever on the mirror box side has returned to the original position, body side charge lever (3010) operates in the direction of arrow to shift X lever (0205) in the direction of arrow, then X contact (2188) is separated from X contact plate (0207) to become OFF.

11

1. As the second curtain runs, second curtain shutter gear (2107) rotates in the direction of arrow and pushes second curtain brake lever (2181) at ⑧ of second curtain shutter gear (2107) just before the end of rotation (just before completion of 2nd curtain running).

2. Second curtain brake lever (2181) kicks mirror return lever lock claw (0522) on the mirror box side to reset the mirror preset system.

6. Mirror Box Mechanism

A. Mirror (45°) retaining mechanism

Mirror operation lever B (5116) is free before and after winding. It is pushed down by mirror operation lever spring (5117), then mirror holder (0550) being engaged with mirror operation lever (5116) is retained at 3 points of mirror stopper (5111), mirror support A (5110) and B (5113), thus keeping the mirror angle at 45°.

B. Mirror raising and lowering mechanism

〈Raising〉

1. Operation of release magnet causes mirror release bar (5021) being engaged with release operation lever C (0571) to operate in the direction of the arrow. Then it is disengaged from mirror operation lever (0521) at ⓐ, and mirror-up spring (5042) moves preset operation lever (0523) and mirror operation lever (0521) in the direction of the arrow.
2. Operation of mirror operation lever (0521) causes mirror operation lever-B (5116) to operate in the direction of the arrow. Then mirror holder (0558) being engaged with mirror operation lever-B (5116) is raised.

〈Lowering〉

1. When the second curtain has completed running, preset operation lever (0523) is returned in the direction opposite to the arrow, and mirror operation lever (0521) is also returned. Then mirror operation lever-B (5116) is returned by mirror operation lever spring (5117) along with mirror operation lever (0521), and then mirror holder (0558) is lowered.
2. On the other hand, the release magnet is returned on returning of preset operation lever (0523), then release operation lever-C (0571) is operated in the direction opposite to the arrow, and mirror release bar (5021) and mirror release lever (0503) are returned by spring, thus stopping mirror operation lever (0521).

C. Preset mechanism

〈Operation〉

1. Operation of the release magnet causes preset operation lever (0523) to operate in the direction lever (0523) to operate in the direction of the arrow. Then preset lever (0532) and preset operation plate (5048) are operated in the direction of the arrow via preset connector (5047). Thus the mirror is raised at the same time with stopdown operation.
2. The rotation of preset operation plate (5048) is transmitted to flywheel (0542) via speed increase gear (0541), thus controlling the entire system.

〈Returning〉

1. On completion of the second curtain running, mirror return lever lock claw (0522) is kicked in the direction of the arrow, releasing it from mirror return lever (0524), and then preset operation lever (0523) is returned along with mirror return lever (0524) by the function of mirror return spring (5044), and also preset operation plate (5048) is returned via preset connector (5047), thus the mirror is lowered.
2. As preset connector (5047) operates, preset lever (0532) is returned by preset lever spring (5051) in the direction opposite to the arrow, then the diaphragm is released.

7. Principle of Metering and Description of Circuit

A. Outline

- Function

The electric circuit of XG has various functions as follows:

1) Automatic exposure control and shutter speed indication by LED.

2) Manual exposure control.

3) Shutter sec. time auto changeover and blinking indication by exclusive strobe.

4) Bulb exposure control.

5) Touch switch.

6) Magnetic release.

7) Electronic self-timer and blinking interval variable indicator circuit.

8) Voltage detection (incl. B.C)

9) Winder control.

- Composition

The circuit of XG is complicated having a lot of functions, and therefore solid-state construction is employed as much as possible for the circuit. It basically consists of two monosyllic ICs with 20 pins each for metering, operation, control (IC 1), and for indication (IC 2), one monosyllic IC with 10 pins mainly for self-timer (IC 3), and hybrid IC (HIC) for the purpose of connection between magnetic release and each circuit. To cope with such complicated wiring, a flexible circuit board is employed.

The switches are also transistorized as much as possible. Trigger switch, the representative one of mechanical switches, is of OFF type to minimize the influence of chattering. For the brushes of sliding resistors such as ASA resistor and diaphragm resistor, the number of brushes is increased in order to reduce noise. Also, 12 LED's are built into the indication board as indication elements.

B. General description

- Metering system

XG is a single-lens reflex camera using TTL metering system. And the amount of light to CdS is changed and shut off due to camera operations (such as auto exposure control and mirror operation).

It is therefore necessary for the camera to memorize the result of TTL metering (exposure time in XG) just before release.

- Memory system

XG employs such a system that both in auto and manual the exposure time is converted into an electrical amount (voltage) and it is charged into a condenser and then the charge voltage is memorized by the camera. Also, the system is to memorize logarithmic values because the metering range and film sensitivity interlocking range are wide; interchangeability is required for lenses and parts, making the circuits complicated; and the range of memorized values (exposure time) is also very wide.

- Metering switch

In order to prevent wasting of the battery due to forgetting to turn off the metering switch, the metering switch is interlocked with the release button. A touch switch is installed to improve the maneuverability during metering. (A touch switch uses a part (finger) of the user's body as a switch contact. So, when the user wears gloves, the finger will not serve as a contact. In that case, pressing the shutter button by one step more will turn on the metering switch.

Each mode of XG is described in accordance with the block diagram.

• Automatic exposure control system

1. Metering system

In the auto exposure control system of XG, the film sensitivity, aperture, and exposure correction value are preset. The exposure time is automatically determined according to these values and the brightness of the scene to achieve the appropriate exposure.

When metering switch (S₁ or S₁₁) is turned on, the film sensitivity and exposure correction values are mechanically added, and the values are converted into resistances, making the rotating angle constant per step, and the aperture value is also converted into a resistance value (logarithmic operation). These electrical amounts (resistances) and the brightness of the scene are treated by the photoelectric converter consisting two CdS and resistors, and the resultant electrical amount (resistance) is put into the calculation circuit. (The converted value (brightness of scene) is subjected to logarithmic compression during calculation.)

The result of calculation is an electrical amount (voltage) corresponding to the exposure time, which is charged into condenser (C_1) . Then, the exposure time is indicated in the finder by LED through the indication circuit.

The calculation in the above is as follows:

$$ \mathrm{TV} = (\mathrm{BV} - \mathrm{AV} _ {0}) + \mathrm{SV} - \mathrm{P} $$

TV : Shutter speed

BV : Brightness of scene

AV_0 : Max. aperture value

SV : Film sensitivity

P : Number of steps for set aperture

2. Control system

The control system of XG is more complicated than that of XE because XG employs a system that the desired exposure is achieved when the shutter is released.

When release switch (S₂) is operated, the release circuit operates to check to see that the shutter sec. time is within the interlocking range. At the same time, the power source voltage is checked by the voltage detecting circuit. And only when the conditions are satisfactory, the release magnet is operated to start the mirror system. On operation of the release magnet, the memory circuit operates to store the voltage corresponding to the exposure time at that point into condenser (C₁) for memory.

Even when the light to CdS is changed and shut off due to auto exposure control or mirror operation, the charge voltage already stored in the condenser will not be affected at all. As the operation is further performed, the first curtain starts running and the trigger switch operates in connection with the first curtain, then the control circuit operates to change the stored voltage into logarithmically expanded current.

Condenser (C₂) is charged with the current, and when the charge voltage reaches a certain level, the current of shutter control magnet is cut off by the function of the control circuit, then the second curtain runs to complete the exposure. When the exposure is completed, the mirror system is reset and the winding stop is released.

The circuit reset switch (S _4 ) being interlocked with the winding stop turns off to reset the release circuit.

The indication LED turns off with S_2 turned on. When the release button is kept depressed, LED turns on again with reset switch ( S_4 ) OFF.

- Manual sec. time

When the speed dial is set to 1\~1/1000 sec., the mode selector operates and the standard resistor is set instead of CdS, then the film sensitivity and override resistance are changed over to manual resistor. Also, the diaphragm resistor is released from the circuit and the power supply to the indication circuit is cut off, hence the indication LED does not light up.

When metering switch (S₁ or S₁₁) is turned on, the calculation is performed by the standard resistor and manual resistor, then voltage corresponding to the set sec. time is charged into condenser (C₁). Next, when release switch (S₂) is turned on, the power source voltage is checked by the voltage detecting circuit, then the release magnet is operated. The operations, after that, are the same as for the control system in auto mode.

When XG is used with manual sec. time, shutter sec. time is memorized. So, the shutter is controlled at the initially set speed even when the set speed is changed during shutter operation.

- Bulb mode

When the speed dial is set to "B", the mode selector operates to turn off the power source holding circuit, and power supply to the indication circuit is also cut off, then the indication LED does not light up. Next, when release switch (S₂) is turned on, the power source voltage is checked by the voltage detecting circuit, and then the release magnet is operated. As the operation continues, the trigger switch operates, but the bulb is given priority by (S₃) over control circuit, therefore, the shutter control magnet keeps operating while the release button is depressed, then the second curtain is stopped. When the release button is returned to the original position, release switch (S₂) is turned off and the power source holding circuit is also off, therefore, the shutter control magnet turns off thus completing the exposure.

- Strobe auto

When the exclusive strobo has been completely charged, the mode selector circuit is shifted to Strobo Auto, then the signal from the strobo enters the indication circuit and control circuit; blinking indication of "60" is given by the indication circuit and the exposure at the strobo-tuned speed (1/60) is done by the control circuit when the shutter is released. (When the bulb is used, however, the auto changeover to the tuned speed is not performed by the function of the mode selector.)

Indication…When used in auto mode, auto sec. time is indicated until completion of charge, but the changeover operation of the mode selector causes the indication signal on the camera side to turn off, and then "60" is turned on and off by the signal on the strobo side. When used in manual mode, the indication is off, therefore the indication "60" is turned on and off by the signal on the strobo side on completion of strobo charging.

Speed auto changeover…When released on completion of strobo charging, the releasing magnet operates to start the first curtain. At that time, the control circuit instantaneously operates to turn off the control magnet with the strobe signal, but the control magnet is kept ON by the strobo signal. As the operation continues, the synchro switch turns on when the first curtain nearly completes its running, then the strobo flashes, the signal from the strobo to the control magnet stops, the control magnet turns off, then the second curtain runs and the mode selector also returns to the original position.

- Electronic SELF

When the SELF changeover switch is set to "SELF", the mode selector operates to change the composition of the release circuit to the circuit for self-timer.

When release switch (S₂) is operated, the self-circuit operates and then LED for SELF operation indication (LED for B.C indication is used) blinks at constant intervals.

After release switch operation, the release circuit operates 8\~12 seconds later to release the shutter. Then the signal is given to the self indicator circuit by the release circuit (self circuit) 1/4 (about 2.5 sec.) before the total self-time length.

The self-timer operation indicating LED then blinks at faster intervals, thus giving a previous notice for shutter release.

- Transistor switch

A conventional mechanical switch was operated by the movement of the release button or mirror, and the setting was maintained mechanically. Chattering was liable to occur when the switch turned on in particular. In the case of a transistorized switch, having a composition as illustrated below, the input (from circuit B) is electrically applied to the transistor to turn on and off. Also, the setting is retained by maintaining the input level. Since a transistor switch has no contact, it does not include mechanically operating parts and assures excellent durability being free from chattering.

C. Description of circuit

The circuit of XG is explained in accordance with the block diagram.

1. Mode selector circuit

This is the general name for circuits which select the mode in accordance with the switch operation or external signal (signal from strobo).

Auto mode: S_8 , S_9 , S_10 ……A side S_5 ……ON

Manual mode: S_0 , S_1 , S_10 ……M side S_3 ……ON

Bulb mode: S_8 , S_9 , S_10 ……M side S_5 ……OFF

Exclusive strobo mode:

On completion of strobo charge, the shutter speed control signal enters the control circuit and the "60" LED blinking indication signal enters the indication circuit respectively through the contact shoe.

Electronic SELF mode: S_4 ......SELF side

2. Metering switch (Touch switch)

The switch (S₁) operates when touch switch (S₁₁) and shutter button are lightly pressed (about 0.5 mm).

Touch switch (S _11 ):

The periphery and the center of shutter button are electrodes. When it is touched, the resistance between the electrodes decreases ( several M ohms).

This is electrically detected Tr3,Tr6 , and then Tr_1 operate) and then power is supplied to the metering circuit.

3. Voltage detecting circuit

If the power source voltage becomes lower than the specification during photography, Tr turns off and the release circuit stops working. The basic construction is as shown at left.

The B.C circuit is the same as this in principle of operation. It uses B.C indicating LED instead of release circuit.

4. Metering operation circuit

This circuit converts the change in brightness into the resistance of CdS, adds the aperture value and film sensitivity information, performs logarithmic compression, and puts out the signal to the indication circuit and memory circuit.

Auto Mode:

It consists of CdS and two resistors. Even if the resistance of CdS circuit changes (the brightness of the scene changes), the voltage applied to the circuit is kept constant by the operational amplifier, thus making the current (i_1) proportional to the brightness. The current (i_1) , SV and AV information from the resistors are treated by the operational as voltage corresponding to the exposure time. The voltage is applied to the memory circuit and indication circuit through the level shift circuit (including VR_2 , VR_3 ).

Manual Mode:

When the mode is shifted to Manual, CdS circuit is switched to standard resistor (VR _1 ) to make current (i) constant. Also, the brush of SV resistor is switched to that of TV resistor (resistor is used). Therefore, the output to the memory circuit varies in accordance with the position of the brush for TV resistor.

5. Indication circuit

The indication circuit is a combination of comparators, which compares the output of calculation circuit and the standard voltage created in the indication circuit. When the values are close to each other, the corresponding LED is lighted. When the output of calculation circuit is between standard voltages intermediate range), two LED's are lighted.

The output of calculation circuit is compared with the standard voltage by comparators in the indication circuit (IC 2). When the values are close to each other, the corresponding LED is lighted. When the value is in an intermediate range, the outputs are given from two comparators to two LED's to turn them on at the same time.

When the over-range warning LED is lighted the over-range lock signal is given to the release circuit to lock the release. Also, when the signal for charge completion is emitted from exclusive strobo (8668), the comparator is turned off (LED OFF), then LED "60" is turned on end off by the signal.

6. Magnetic release

With the contact piece attracted by the permanent magnet, the permanent magnet is temporarily demagnetized. Then the contact piece operates to release the mirror box. Condenser C_4 is charged through R_5 beforehand. When Tr_4 in operated by the release circuit, condenser C_4 serves to create a magnetic field, opposite to that of the permanent magnet, on the magnets provided around the permanent magnet. Then the permanent magnet is temporarily demagnetized thus releasing the contact piece.

7. Over-rang lock

When release switch (S₂) is turned ON, C₃ is charged at a high speed, and the release circuit operates on completion of charge. In the case of over-range non-interlocking operation, C₃ is discharged not to operate the release circuit. When over-range LED is lighted in the indication circuit, Tr operates as well and C₃ is shortcircuited at both ends. Therefore, C₃ will not be discharged and the release circuit will not work.

8. Memory circuit

This circuit stores the output of calculation circuit into condenser (C 1 ) through VR 2 and Tr switch.

The calculation circuit output (voltage corresponding to shutter speed) is charged into condenser (C_1) through VR, and Tr SW. But Tr SW. is turned OFF when Tr_4 is turned ON, and the calculation circuit is isolated from condenser (C_1) . Then the shutter speed is memorized.

1. Logarithmic expansion circuit

The memorized voltage cannot be used as it is because it has been logarithmically compressed. It must be changed to the original value. (This is called "logarithmic expansion".)

When the first curtain runs and trigger switch (S 1 ) turns off, Tr SW. is activated to operate Tr for expansion. The size of current (IC) flowing in Tr for expansion varies depending on the voltage charge in C 1 . When the charge voltage of C 1 is increased by 18 mV, the current is doubled (characteristic of Tr). Also, C 2 is charged by the current flowing in Tr for expansion, and when the charge voltage reaches a certain level, the control circuit operates causing the second curtain to run.

1. Control circuit

In the logarithmic expansion circuit, condenser (C₂) for time constant is charged by the current subjected to logarithmic expansion. The shutter speed is controlled by the charge voltage. When C₂ has been charged up to a certain level, the comparator operates to turn off Tr. and then the shutter control magnet is turned OFF. Then the second curtain is released to start running.

1. Power source holding circuit

This circuit holds the power source until the end of shutter operation even when the release switch is turned off during operation of the camera.

When release switch (S₂) is turned ON, Tr operates to supply power to the release circuit and metering circuit, starting up each part. When release switch (S₂) is turned OFF, power source is held by the function of Tr, the same as with S₂ ON. With release completed, the set lever returns and circuit reset switch (S₄) is turned OFF, then the power holding circuit is also reset.

12. Bulb mode

A bulb switch (S 1 ) is installed in the power source holding circuit. On turning off of the holding circuit, priority is given to "B" over the control circuit. And second curtain release is done by release switch (S 2 ).

When the shutter speed dial is set to "B", bulb switch (S 1 ) is turned OFF and the metering operation circuit is shifted to Manual. Next, when release switch (S 2 ) is turned ON, the voltage is detected to operate the release circuit, and the shutter opens. While release switch (S 2 ) is ON, T 1 operates and Mg 1 is ON (open). When release switch (S 2 ) turns off, power supply to the control circuit is cut off because the power source holding circuit is OFF. Then the shutter control magnet (Mg _1 ) turns off and the second curtain starts running.

13. Magnetic SELF

For ordinary photography, the release circuit is operated as C_s is charged (high speed). The circuit composition and the shutter speed have been changed in this self-timer.

When the mode selector switch is set to "Selftimer", the self switch (S 4 ) turns ON and Tr switch turns OFF. Next, when release switch (S 2 ) is turned on, C 3 is charged through C 4 . And the release circuit operates 8\~12 seconds later to activate the release magnet to operate the shutter. The indication LED blinks by the function of the SELF indication circuit consisting of C 4 and resistors in series. When the charge voltage of C 3 has reached a certain level, the composition of indication circuit changes causing the blinking intervals of LED to become faster.

14. Remote-control

In ordinary photography, metering switch (S₁ or S₁₁) turns ON and release switch (S₂) turns ON and then the shutter is operated. In remote control operation, the metering switch does not turn ON, therefore power is supplied to the metering circuit after release switch (S₂) is turned ON.

15. Winder control function

Unlike XD, XG is not furnished with a winder switch but provided with the signal from the reset switch (S _4 ) for the purpose of winder control. The winder operates when the winder terminal voltage is zero, and it stops when voltage exists.

The winder terminal voltage is 2V with S 4 ON, and 0V with the switch OFF. Also, S 4 is ON with winding completed, and OFF with shutter release completed.

16. Strobo Auto

The circuit receives the signal of stobo (8668) and indicates for strobo charge completion in the finder and changes the shutter speed to the strobo-tuned speed.

When the charge of strobo has been completed, pulse signal enters the signal contact on the camera side from the signal contact on the strobo side. The pulse operates Q_1 Q_2 . Q_1 turns off the indication circuit. Q_2 holds the magnet, and Q_3 charge the condenser ( C_2 ) for time constant in the control circuit at a high speed (approx. 1/1000 sec.). Also, Q_4 operates at 2V and doesn't at 1.6V. Therefore, indication LED ("60") turns on and off.

When the shutter is operated and X contact is closed, the strobo flashes and the strobo signal goes out. Then Q: which held the magnet is turned off and the second curtain starts running, thus completing the exposure.

※ 1. When HIC (2006-4304-02) with no lead wire § 34 is replaced with a type after -03, the soldering position of §34 should be different. (Refer to P.46 - 48.)

※ 2. Since the shutter block is grounded to ⊙ of power supply, X earth plate (2204) and lead wire 20 are not needed and have discontinued. (Allowable to remove.)

※ 3. New type of 2019-0580 has been modified so that it can be grounded to of power supply from magnet base plate. So, earth wire (Black) has been discontinued.

※ 4. Shutter block is grounded to ⊙ power supply the same as in *2. So, §14 is not needed and has been discontinued. (Allowable to remove.)

※ 5. For bodies of which (inclined) indication cannot be adjusted by R8, lead wire ( 24) is used instead of R8.

1. In bodies at the initial stage of massproduction, the positions of §2 and §19-2 are opposite to those in this wiring diagram. (If AM switch is in normal conditions, there is no problem of positions.)

※ 7. In the case of Black body, the top cover cannot be grounded to ⊙ of power supply. Therefore, CdS circuit base plate (2006-0596) with earth contact and lead wire (23 are required. (For discontinuance of contact, refer to P.25)

The details of modifications of parts provided with ● or ● in pages 1 through 19 are explained in the following.

1. They are classified into Types A\~B or Types A\~D according to the frequency of modifications, and the differences are mentioned in tables.
2. The parts are interchangeable with other types only when they come in a set with the relative parts of each type.
3. When there are relative parts to be modified, the part cannot be individually modified to other type. The relative parts must also be modified to make set part.
4. For parts of previous type which cannot be supplied, (×) is attached to the tail of the part number in the table. If it is necessary to modify the (×)-marked part, replace it with other type.

- Do not use Type A for bodies with Type B attached. (It may cause shortcircuit.)

Top cover set for XG-E XG-E川上カバーセノト

CdS circuit base plate set CdS基板七卜

When replacing the top cover set Types A\~C of P. 22 with Type D (or replacing only the relative parts of contact with Type D), it is necessary to modify the way of finishing (replacing) or CdS P.C. board set mentioned below and the lead wiring method.

1. Drill the fastening pins of CdS P.C. board set and remove the contact. Also, cut off the part above the dotted line by nippers. (It is also allowable to replace it to Type D (2006-0596-02)).

1. Replace the lead wire _21 (white) and _22 (green) with those 25\~30 mm longer. • In the case of black body, replace _23 (black) with a longer one as well.

1. Connect each lead wire.

3. Set charge lever (3016) on charge pin (9228) of mirror return lever (0524). Caution: Take care not to deform charge lever and mirror return lever.

• After mounting, do the following checks.

1. Winding operation is smooth without catching or the like.
2. Shutter and preset are charged with over-charge volume assured.
3. Release magnet does not become loose due to winding shock or the like.
4. When release connecting lever-C (0571) is operated, preset mirror mechanism operates and shutter is release. But the curtain does not open when shutter is at high speed condition.
5. After releasing, when winding stop lever is set free by charge lever, the next winding is possible.
6. Clearance between charge lever (3016) and charge pin (9228) is not excessive.

① Measurement of CdS resistance value and selection of R_1 , R_2

■ Measuring instruments:

: Digital tester (Type 2507)
: Luminescence box (Model L-222 or L-223)
: Standard lens (50 mm, F 1.4)
: ND filter (MINOLTA ND 50% FOR ADJUSTMENT)

■ Measuring method

1. Disconnect green lead of CdS board (0591) and soldered R_1 and R_2 as illustrated below. Then connect lead wire for measurement to R_1 .

1. Measurement of RmV5 (Resistance should be within 10\~40KΩ) Set digital tester range to "Ω", set ND filter on body and then measure resistance value at luminance EV 11 (ASA 100).
2. Measurement of RHV10 (Resistance should be within 1.6\~5.8KΩ) With CdS connected as above, remove ND filter and measure resistance at luminance EV 15 (ASA 100).

■ Selection of R_1 , R_2

From resistance values of Rbv5 and Rbv10 obtained by CdS measurement, R_1 and R_2 can be calculated as follows:

1. How to obtain from formula

$$ R _ {2} = R _ {\mathrm{RV}} 5 \left{\frac {1}{4} \left(\frac {R _ {\mathrm{BV}} 1 0}{R _ {\mathrm{BV}} 5}\right) ^ {0. 1 0 7 5} - \frac {R _ {\mathrm{RV}} 1 0}{R _ {\mathrm{RV}} 5} \right}. \tag {①} $$

$$ R _ {1} = \frac {\left(R _ {B V} 5\right) ^ {2}}{R _ {2}} \dots \tag {②} $$

Pick up resistances which are proximate to the obtained resistance values from the following table, and then solder R_1 , R_2 and lead wire (Green).

- NOTE: When R_2 is (-) in formula ①, the combination of CdS is defective.

When R_2 is larger than 1.8KΩ in formula ①, the combination of CdS is defective.

When R_2 is smaller than 0.11KΩ in formula ①, shortcircuit R_2 with lead wire.

1. How to obtain from table

a. Select value of R8v5 or proximate value from vertical axis.
b. Select value of Rsv10 or proximate value from horizontal axis.
c. Find the intersection of a and b.

The values thus obtained are R_1 , R_2 and lead wire (Green): R_1 at top and R_2 at bottom. Then solder R_1 and R_2 obtained from the table.

• NOTE: When R_2 is 0, connect lead wire to R_2 .

If the intersection of Rsv5 and Rsv10 is blank, the combination of CdS is defective.

(Ex.) R_Bv5=20.4K , R_Bv10=1.69K

a. Approximate value of 20.4KΩ = 20KΩ.
b. Approximate value of 3.69KΩ = 3.6KΩ.
c. Place 20KΩ on vertical axis and 3.6KΩ on horizontal axis. From the intersection,

R_1 : 1500KΩ and R_2 : 0KΩ can be obtained.

■ Calculation Table

② Determination of R_4 -180 mA adjustment-

■ Measuring instruments:

: Camera standard tester (ST-5101) or
Constant voltage D.C power supply (Model E-1 or E-2)
: Resistance selector (Model RS-Ⅲ)
: Digital tester (Type 2507)
: Battery adapter (2006-0415-75)

■ Standard value: 180±2 mV

■ Adjustment procedure

1. Disconnect R_4 as illustrated below. Connect lead wire for measurement to R_4 (terminals ⑱, ⑲ of IC-1) and then set it on the measuring instrument.

1. Set power source voltage at 2.8V and metering switch ( S_1 ) to ON. Then select R_4 resistance by the following method.

a. Change the range of Rp resistance selector to select Rp resistance where the digital tester indicates around 180 mV.
b. From the obtained Rp resistance, select R_4 resistance which is proximate to 180 mV from the table below. Then solder it to terminals ⑱, ⑲ of IC-1.

For example, when the resistance value of Rp resistance selector is 18 KΩ, the value indicated on digital tester is to be V 18 (mV).		Comparison of voltage (mV)	R_4 used (KΩ)
		V_18 - 180 ± 2	18
Resistance of Resistance selector (KΩ)	Indication of digital tester (mV).	V_18 < 180 ≤ V_26	18
		V_30 < 180 ≤ V_24	22
18	V_18	V_24 < 180 ≤ V_30	27
20	V_20	V_30 < 180 ≤ V_34	33
24	V_24	V_36 < 180 < V_47	39
30	V_30	V_47 - 180 ± 2	47
36	V_36	V_47 < 180 ≤ V_62	56
47	V_47	V_62 < 180 < < V_100	68
62	V_62	V_62 < < 180 < V_100	82
100	V_100	V_100 - 180 ± 2	100
200	V_200	V_200 - 180 ± 2	200
∞	V_∞	V_200 < 180 < < V_∞	200
		V_200 < < 180 < V_∞	390

c. After soldering R, resistor, remove Rp resistance selector. Then make sure that indication of digital tester is 180 ± 2 mV.

(Ex.) When Rp resistance is 24KΩ, indication of digital tester is 175 mV; and when Rp is 30KΩ, the indication is 181 mV. V 24 = 175 < 180 < 181 - V 30 . Therefore, R _4 is 27 KΩ as obtained from the table.

Trouble Shooting Chart

I. Hints on use of Trouble Shooting Chart

1. This chart includes the symptoms and causes of troubles on the camera side.
2. Even when a symptom appears on the camera side, the trouble is not always on the camera side but in connection with the replacement lens, winder or exclusive strobo. Therefore, carefully check operations related to the auxiliary parts before using this chart.

2. Contents of Chart

1. Mentioned in this chart are only individual patterns and these cannot cover all possible causes.
   Regarding multiple causes, carry out an all-round investigation of the trouble.
2. The chart mainly covers electrical causes and to a certain extent mechanical causes.

3. Precautions for Work

1. A digital tester (2507) is to be used as the measuring instrument. It is also allowable to use other measuring instruments when the input impedance exceeds 10 MΩ.
2. Use the measuring instrument to check voltages, and a tester of less than 3V to check current conduction.
3. It can be safely said that troubles of electric parts such as IC's diodes, transistors, resistors, capacitors, etc. seldom occur. It is therefore practical to put emphasis on checking for defective soldering of lead wires and electric parts, defective switches, etc.
4. When checking for defective soldering, do not excessively press the parts or pull the lead wires.
5. When measuring voltage, attach a pin to the end of alligator clip because the portion measured is very narrow. Do not directly connect the alligator clip with the portion measured; otherwise damage to the electric parts or to the pattern may occur.
6. When measuring the switch operation pattern, take care not to scratch the pattern outside the switch operation range. In case of a switch contact, take care not to disturb the switch contact.
7. When removing electric parts, pull out the power supply cord.
8. The desirable soldering iron temperature is about 260\~300°C. In any case, finish soldering in a few seconds. Be sure to remove chips before soldering.

4. How to use the Trouble Shooting Chart

1. The chart includes check points in detail ranging from the appearance of symptoms to the finding of causes.

2. The flexible circuit board should be normal.

3. The voltage at each check point is to be the normal voltage when SW.1 and SW.7 are set to ON with winding completed (before releasing), 3.0V power supply (constant voltage), and 1/30 AUTO.

4. The earth is not connected to the body, check the earth on the flexible circuit board.

5. The indications in the Trouble Shooting Chart are Symptom, (Symptom to be checked), Check point, Normal voltage at check point, Defective voltage, Possible cause, Probable cause, and the marks in circles stand for check points in the flexible circuit board and circuit diagram.

5. Battery capacity checking method

1. Connect the 100Ω resistor to the battery as illustrated. Also, connect a digital tester or voltmeter in parallel with the resistor and then measure the voltage. The measurement should be done in a short time to avoid excessive consumption of battery power.

2. The battery is normal if the measured voltage is over 1.4V.
