PURPOSE:To take up and rewind securely a film by preventing the malfunction of a camera when the film is taken up or rewound. CONSTITUTION:The 1st operating member 16 is not pressed in during normal photography. When the film is rewound, a switch 3 is closed to rotate a motor 2. At this time, the member 16 is pressed as shown by an arrow A and the 2nd operating member 17 is then slid as shown by an arrow B to engage notches 23 and 28 with each other. The switch is closed after a leaf spring 25 and a pin 24 are brought into contact, and a switch 4 is opened at this time to eliminate the unnecessary power consumption of a release circuit 12, camera control circuit 13, flash circuit 14, etc., so that the sufficient capability of a power source 1 is used only to drive the motor 2. As the switches 3 and 4 are operated in associative order, the operation is never reversed because of the inversion of the operation order. |
