Rewind interlock for APS camera
摘要:
The camera of this invention preferably includes a rewind interlock that prevents the double exposure of film. Preferably, the camera of this invention is an Advanced Photo System (APS) camera that employs APS film. Such APS film may be contained in a film cassette that has a light lock door. The rewind interlock prevents thrusting or pulling a frame of film from the film cassette after that frame of film has been exposed and rewound into the film cassette. This prevents the accidental double exposure of a frame of film. In a preferred embodiment of this invention, the rewind interlock prevents thrusting or pulling film from a film cassette after all of the film has been rewound into the film cassette. Preferably, the rewind interlock prevents the thrusting or removing of exposed film from a film cassette. The rewind interlock does this by preventing the film advancing mechanism from being manipulated in a direction that advances film from the film cassette after the exposed film has been rewound into the film cassette. The rewind interlock may be reset to permit the advancement of film from a film cassette by the removal the film cassette from the camera.
