Abstract
A film feeder for a camera comprises a feeding out mechanism for feeding out film of a film cartridge wound around a spool shaft, by rotating the spool shaft of the loaded film cartridge; a winding up mechanism for driving a wind up spool to wind up around the wind up spool the film fed out of the film cartridge; a roller provided between the loaded film cartridge and the wind up spool, which is driven by the driving power of a motor to feed the film fed out by the feeding out mechanism and guide the film to the wind up spool; and a driving power transmission mechanism for transmitting the driving power of the motor to the roller until the film is wound around the wind up spool and thereafter cutting off the transmission of the driving power to the roller.
Claims7
A film feeder for a camera, including:
- a feeding out mechanism for feeding a film wound around a spool shaft out of a cartridge by rotating said spool shaft;
- a winding up mechanism for driving a wind up spool for winding up around said wind up spool the film fed out from said film cartridge;
- a roller provided between said film cartridge and said wind up spool, which is driven by the driving power of a motor to feed the film fed out by said feeding out mechanism and guide the film to said wind up spool;
- and
- a power transmission mechanism for transmitting the driving power of said motor to said feeding out mechanism until said film reaches said roller and thereafter cutting off the transmission of said driving power to said feeding out mechanism, and for transmitting the driving power of said motor to said roller until said film is wound around said wind up spool and thereafter cutting off the transmission of said driving power to said roller.
