(Operation)
1. When R button is pushed, sprocket shaft is pushed up causing sprocket clutch pin to be
disengaged from sprocket groove. When sprocket shaft is pressed down, R button lock
lever is fitted in sprocket shaft groove. At the same time, winding claw release pin is
pushed by R button lock lever, then winding claw is disengaged from winding gear claw.
2. When winding lever is operated in that condition, winding gear doesn’t rotate because
winding claw is disengaged from winding gear claw. Therefore, neither spool nor film
counter do not operate.
3. When R button is pushed and winding lever is operated, film is not fed but charge coup-
ler is rotated. So, shutter and MP drive mechanism are charged making multiple exposure.
possible.
Also, winding claw lock plate is operated in the direction of the arrow by winding claw
spring just after start of winding shaft. Thus, winding claw operation is controlled by
bend @ to eliminate deflection of multiple exposure.
(Release)
1. At the final stage of winding operation, R button lock release pin of charge coupler
pushes ® of R button lock lever to return the lever to the original position, and then
sprocket shaft is also returned. Therefore, film is fed by the next winding operation
unless R button is pushed again.
