PURPOSE:To prevent part of a photograph frame from becoming absent in development processing by inhibiting a shutter from being released during the preliminary winding operation of a film from a cartridge to a take-up spool and specific-quantity rewinding operation. CONSTITUTION:A quantitative brush 10 and a counter brush 15 are held in contact and contacts 6 and 8 are still made until the film which is wound preliminarily is rewound from the take-up spool to the cartridge. When a counter drum 14 rotates counterclockwise by a specific angle theta according to the rewinding operation of the film, the quantitative brush 10 and counter brush 15 leave each other and the contacts 6 and 8 are broken to inhibit the shutter from being released. Thus, those operations are completed and then photography is held in readiness while the film is rewound into the cartridge. Therefore, the length from the end of the film to the 1st frame is increased and absence of part of a photograph frame during development processing is prevented.
