Abstract

PURPOSE:To reduce friction to lessen the load, by providing a charge cam on a shaft, which is turned in accordance with turning of a film winding lever, in a film winding mechanism for camera. CONSTITUTION:The turning of a film winding lever 1 is transmitted to a gear 20, which is formed as one body together with a shaft 21, through a one-way clutch. This turning is transmitted to a gear 64, which is attached freely turnably to the shaft 21, through shutter gears 49 and 51, a sprocket gear 53, etc., and a charge cam 65 formed as one body together with this gear 64 charges a mirror and a stop mechanism. When a motor is driven, the driving force is inputted from a coupler 67 to the gear 64 in one body, and the rotation is transmitted through a route opposit to that for the manual operation and reaches the gear 20. Since the shaft 21 and the gear 64 are always turned in the same direction, friction for the winding operation is reduced to make the film winding light.
