ABSTRACT:
Driving power of an electric motor is transmitted to wind up a photographic film on a spool and to charge the shutter and other mechanisms associated therewith. When the spool has wound up the film by one frame, the transmission of the driving power to the spool is cut off through a clutch mechanism. After the charge member has completed its operation of charging the shutter and the motor is de-energized, the clutch mechanism is rendered effective in response to return of the charge member to the initial position, whereby the transmission of the driving power to the spool is again ready to be performed.
