ABSTRACT:
A film-rewinding apparatus to rewind a film from a cartridge into a container which can accommodate the film therein by inserting the film from an opening of the container. The apparatus comprises a cartridge-supporting portion which supports the cartridge; a shielding door driving mechanism for opening and closing the shielding door; a spool-driving mechanism for feeding the film out by driving the spool; a container-supporting portion for supporting the container; an opening and closing driving mechanism for opening and closing the opening; and a film-dismounting mechanism for dismounting the film from the spool. The film-rewinding apparatus can easily perform rewinding by only operating a handle or lever, or by a switching operation, after the cartridge and the intermediate magazine are set and the cover is locked.
