ABSTRACT:
A film winding/rewinding device has a power transmitting shaft extended between the film spool chamber and the film cartridge chamber of the camera. The rotation of the output shaft of a motor disposed with the axis of the output shaft perpendicular to the axis of the power transmission shaft is transmitted by a first worm gearing to the power transmission shaft. When winding the film held on the film holding spool of a film cartridge, the rotation of the output shaft of the motor in the normal direction is transmitted to a film winding spool by a second worm gearing connected to the power transmitting shaft to wind the film. When winding the film, any power is not transmitted to a film rewinding fork disposed within the film cartridge chamber. When rewinding the film, the rotation of the output shaft of the motor in the reverse direction is transmitted to the film rewinding fork disposed within the film cartridge chamber by a third worm gearing connected to the power transmission shaft to rewind the film.
