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.
