ABSTRACT:
A film winding mechanism of a camera uses a film cartridge in which a film rolled around a cartridge spool is accommodated. The camera has a take-up spool for winding the film that is drawn out of the film cartridge. The film winding mechanism includes a first device, engaged with one end of the cartridge spool when the film cartridge is in the camera, for rotating the cartridge spool. The film winding mechanism further includes a second device, engaged with the other end of the cartridge spool when the film cartridge is in the camera, for transmitting rotation of the cartridge spool in a film advancing direction to advance the film out of the film cartridge to the take-up spool so as to rotate the take-up spool in a film winding direction to wind the film.
