PURPOSE:To prevent a sudden film rewinding action for a camera in which the film is wound preliminarily and then rewound every a frame, by providing a switch coupling to the pushing of a release button to the film rewinding electric conduction path. CONSTITUTION:When a film is not loaded yet, the switches 40' and 40'' are munually switched to the side of a terminal (b) after the film is loaded and wound preliminarily. A switch 44 is closed by a releasing action, and a switch 45 is closed (with a switch 45' opened) in coupling to the end of exposure. Thus a motor winds the film by a frame, and the switches 45 and 45' are closed to stop the motor quickly. As a result, the sudden actuation of the motor is avoided even though the power supply is replaced while the film is rewound. Thus no failure is caused in shooting at a place requiring a quiet atmosphere. |
