5. Assembly and Adjustment of X Synchro Contact
Fasten the X contact seat assembly (05026) onto the body proper (01001) with two screws (FM 1.7 x 2.5).
Insert two synchro cords (02081) through the bottom hole of (01001), solder one cord at the FP contact piece
B (02024) and the other at the F? contact piece C (02025).
6. Adjustment of Shutter Exposure Timing
a. ADJUSTMENT OF BOUNCE STOPPER MECHANISM
Set the shutter speed selector disc (05058) at “B”, and place the camera on the seat of the shutter speed tester
with the edge of the picture format on the side of the cassette chamber of the camera against the outer side of
the last slit of the tester. While holding down the camera, set the speed selector disc (05058) at 1/60 sec.
Measure the exposure timing at 1/60 sec. (16.7 ms). Since the bounce of the 1st shutter curtain has not as yet
been properly adjusted at this stage, the exposure timing at the end of the picture format is generally registered
much faster than at the start or at the centre of the picture format.
Slightly turn the bounce stopper adjust screw (05109) clockwise through the back of the camera body. Repeat
this until the exposure timing at the end is adjusted to be equal to that of the start or at the centre of the picture
format.
Seal (05109) with red lacquer, applying it through the back of the camera body.
With considerable servicing skill, shutter bounce may be detected with unaided eyes without depending on a
tester. In this event, the camera is to be pointed against a bright plane, such as a white wall, and the curtain
travel is visually checked through the camera back.
b. ADJUSTMENT OF SHUTTER CURTAIN SPEED
In this model, the speed of the shutter curtain travel over the picture format (36 mm) is adjusted to be 14±0.3
ms approximately at 20
°
C. However, when our company-recommended shutter speed tester of a digital
computer-type is used, it should be adjusted to be 12.5±0.3 ins, as the slits at both ends of this tester are
located 2mm inward from the edge of the camera’s picture format.
