Abstract
A recyclable camera and film combination for a camera recycling system is disclosed. The camera comprises a film cartridge chamber with a lid, a rotatable dial manually rotated in the same, direction flame by frame, for every shot, both in controlling the initial loading of the film and in winding up the film. Also included are means for automatically rewinding the film in response to the rotation of the dial after the last frame in the film has been shot, means for controlling the lid so as to automatically open when the entire film is rewound into the film cartridge, means for counting the number of film cartridges loaded into the cartridge chamber, and means for making the controlling means inoperative, whereby the lid does not open for the removal of the film cartridge loaded in the cartridge chamber when the counting means reaches a predetermined number of film cartridges and thus prevent the cartridge chamber from receiving any further film cartridges.
