Zusammenfassung:	A film rewind device for compact cinecameras of the type using a film cartridge having no supply spool shaft operable from the exterior thereof but provided with detent means attached to a take-up core, and in which the length of film to be loosely supplied to the take-up chamber of the cartridge can be varied in proportion to the film roll diameter in the supply chamber of the cartridge by the utmost utilization of the fact that the space in each of the supply and take-up chambers varies in proportion to the length of film photographed, and the length of film to be loosely supplied into the take-up chamber can be selected as desired within a predetermined range and that length of film can be rewound exactly.
