Camera with means for preventing closing of a cartridge light lock when a substantial length of filmstrip protrudes out of the cartridge

摘要

A camera includes a chamber for receiving a cartridge having a light lock movable between an open position allowing a filmstrip to exit the cartridge and a closed position sealing the cartridge in a light-tight manner. The camera also includes means for moving the light lock between its open and closed positions. The invention is characterized by means (50) for detecting whether the film is substantially completely rewound into the cartridge, and for preventing the light lock from being moved from the open position to the closed position, when a substantial amount of the filmstrip protrudes out of the cartridge.
