ABSTRACT:
A film cartridge includes a rewinding shaft for rewinding a film, a case having a film exit/entrance and accommodating the film rewound by the shaft therearound in a light-intercepted condition, and a locking mechanism for locking the leading portion of the film in the film exit/entrance in the vicinity thereof, so that the film does not get out of the cartridge more than a predetermined amount or get out of the exit/entrance carelessly. The shaft or a film feeding-out member in the cartridge is set in a predetermined position, so that the shaft or the member is immediately and smoothly connected with a corresponding member of a camera for accommodating the cartridge. A camera accommodates the cartridge to take the advantage. The camera accommodates the cartridge having a film feeding-out mechanism, a film rewinding mechanism, and a portion for accommodating only the film, so that after the cartridge is accommodated in the camera, each mechanism is suitably and automatically driven to perform a film feeding-out operation or a film rewinding operation.
