ABSTRACT:
A motorized film-transporting mechanism for roll film cameras has a motor-circuit switch arranged in the path of movement of a film sensor so as to be closed when a film is present in the camera. A film counter is biased to zero position when the camera back is opened. When a film is present in the camera and the back is closed, the motor is automatically energized to advance the film by a length corresponding to two film frames so as to move this usually spoiled (light-blackened) film length out of the way. The motor is then automatically de-energized and all components are in readiness for subsequent picture-taking and incremental film advance by one film frame each. When all exposures have been made the film is rewound by the motor which shuts down when rewinding is completed.
