Abstract
PURPOSE:To rewind a film at an optional point when the film advance is over, by producing a certain number of pulse signals while a rotor turns by a certain angle in response to the film advance and regardless of the stopping position of the rotor and then resetting a timer circuit. CONSTITUTION:For an automatic rewinding camera, a film 4 is automatically rewound when the advance of the film 4 stops. When a follower sprocket 62 turns in response to the advance of the film 4, a pin 63 provided to the sprocket 62 turns on a film advance detecting switch S2 in the prescribed times to a frame of the film. As a result, a differentiating circuit 94 delivers the pulse signal to display the film advance state to a lamp 95 as well as to turn on and off the transistors 93 and 107. thus a timer circuit is reset. Then a motor 1 is turned reversely when the time set by the timer circuit elapses.
