ABSTRACT:
A processed film is wound again into the film cassette that contained the film therein before processing. The film is subjected to development and/or printing with one end fixed to a spool of the film cassette. Using a film cassette constituted by a rotatable spool having on its peripheral surface capture members for engaging in perforations of the film, a film guide member for guiding the film from a film gate of the cassette to the spool, and an urging device for pressing the film guide member onto the spool and enabling the guided film to be engaged with the capture members, it is possible to separate the film from the film cassette for development and printing and thereafter to wind up the film into the film cassette.
