PURPOSE:To make a camera small in size and to simplify its structure and to improve the transmission efficiency of a motor by using a motor dedicated to rewinding even as a lens driving motor for automatic focusing. CONSTITUTION:The output of the motor 1 is transmitted to a rewinding shaft 11 through a pinion gear 24 provided to its power shaft, a gear 2, a gear 3, a gear 4, a clutch gear 6, a gear 9, a gear 8, and a gear 10. A fork member 12 having a two-pronged tip is provided to the rewinding shaft 11. The fork member 12 couples with the shaft hole of a cartridge and engages a spool shaft, thereby rewinding the film. A clutch shaft 7 is elevated as a slide plate 14 moves in a direction F and lowered as it moves in a direction R. When the clutch shaft 7 is elevated, the clutch gear 6 disengages from the gear 9 and engages a gear 17. The rotation of the gear 17 is transmitted to a shaft 21 through a gear 18, a bevel gear 18a, a bevel gear 19a, a gear 19, and a gear 20. A coupler 22 is provided to the shaft 21. |
