PURPOSE:To urge the user for replacing of films by stopping a motor by the control output of a timer when the winding of the film is not completed within a prescribed time and inhibiting the resetting of the motor until the rear cover of the camera is opened and closed. CONSTITUTION:A time counting circuit which starts measuring time upon starting of power supply to an electrical motor 11 for the purpose of winding a film and outputs a control signal for the purpose of interrupting the power supply to the motor 11 upon elapsing of the prescribed time is constituted of a capacitor 73, a resistor 17 and a transistor 14. A selection switch 20 for resetting the time counting circuit at every completion of the film rewinding of each time in association with the operation after the releasing of the shutter and a regulating member for the releasing of the shutter which prohibits the resetting of the time counting circuit with a switch 20 by prohibiting the subsequent releasing of the shutter when the winding of the film is not completed yet are constituted of a regulating lever 31 and a detecting lever 116. A selection switch 18 which resets the time counting circuit at every opening and closing operation of a rear cover 102 cooperatively with said operation is provided. |
