PURPOSE:To prevent the malfunction due to oscillation and battery replacing operation by providing a clutch and a control circuit with a film-feed-direction storing function in a camera which winds and rewinds a film by motor driving. CONSTITUTION:The rotation of a motor 126 is transmitted to a sun gear 3 through gears 2 and 2'. The sun gear rotates counterclockwise in winding mode, and a planetary gear 4 engages an interconnecting gear 11 to advance the film by one frame and charge a shutter. When the film comes to the end, the motor is reversed by a known method. The planetary 5 engages the gear 7 to enter a film rewinding mode. At this time, a memory switch 103 is closed and a control circuit is held in the rewinding mode. Further, gears 3, 4, and 11, and 3, 5, and 7 are in such a position relation that they engage, respectively when loaded, and the device never threatened with malfunction even owing to battery replacement, etc., on the way of operation. |
