ABSTRACT:
A single-lens reflex camera comprises a gear rotated when a shutter button is depressed, a movable mirror rotated upward to the prescribed position, a stop-driving mechanism, and a control mechanism which transmits the rotation moment of the gear to the movable mirror and stop-driving mechanism to lift the movable mirror so that after the movable mirror is lifted, it actuates the stop-driving mechanism in the stop-down mode.
