Abstract
A film winding unit is removably attached to a film unit so as to engage a coupling gear with a film winding wheel. The coupling gear is connectable to a gear train through a clutch member. While the film winding wheel of the film unit is unlocked, the clutch member is placed in a power transmitting position for transmitting rotational movement of a motor to the coupling gear through the gear train. Upon the film winding mechanism being locked, a large load is applied to the clutch member, so that the clutch member slips into a disconnecting position to disconnect the motor from the coupling gear. In cooperation with the movement of the clutch member into the disconnecting position, a motor inactivating device inactivates the motor. After a release button of a film winding unit is depressed to depress a shutter button of the film unit, a motor activating device activates the motor in cooperation with returning movement of the release button. The rotational movement of the motor causes the clutch member to return to the power transmitting position, and is transmitted to the film winding wheel through the coupling gear.
