1. A device to enable a film strip packaged in a cassette to be installed in a camera, less than the total number of frames to be exposed, the film strip to be rewound into the cassette without rewinding the tongue end of the film into the cassette, the cassette to be removed from the camera, the cassette to be subsequently reinstalled into the camera, and the film strip to be advanced to the first remaining unexposed frame with correct registration with respect to the camera exposure counter and the exposed frame, comprising:

  • a projection disposed near the tongue end of the film strip forming a mechanical stop and arranged to contact the light trap of the film cassette during a rewind operation, thus alerting the user to cease rewinding thereby preventing rewinding of the film end into the cassette, said projection having associated index means alignable with selected teeth of the camera film drive sprocket.
