  • Patent number: 5543877
    Abstract: An automatic film feed camera includes a fork which engages a film cartridge spool to drive film out of the cartridge. When a camera cover closes a film cartridge chamber, the motor driving the fork is energized. If a detector fails to detect proper loading of a cartridge within a given time limit, the motor is turned off. When proper film loading is detected, pulses generated by a rotation detector are counted, representing the quantity of film sent toward the take-up spool. When this count reaches a predetermined quantity, driving of the fork is stopped, and driving of a take-up spool is started. If the detection device for detecting rotation of the fork fails to generate pulses indicating rotation of the fork within a given time limit after initiation of driving the take-up spool, driving of the take-up spool is stopped and the film is rewound into the cartridge by driving the fork in a reverse direction in accordance with the count represented by the sent quantity of film.
