PURPOSE:To reduce the load on a small-sized motor by making quick return of a mirror driving mechanism and an automatic stop mechanism in the initial stage of film winding by the rotation of the motor after a shutter mechanism finishes operation. CONSTITUTION:When a switch is operated associatively with a trailing curtain right before the trailing curtain finishes running, the motot 5 starts rotating counterclockwise to start charging a shutter and advancing a film. At this time, a gear train 3 engaging the mirror quick returning mechanism and automatic stop mechanism also starts rotating in the opposite direction. Then, a clutch mechanism 34 attains to a free state, so a mirror hop-up linking lever 36 and an automatic stop lever 39 are rotated counterclockwise by a spring 40 and stopped by a stopper pin 38 at specific positions. In such a constitution quick return of the mirror quick returning mechanism and automatic stop mechanism is made possible without placing any excessive load on the small-sized motor incorporated in the camera body. |
