Abstract

A reflex camera having a reflex mirror and a light-blocking plate which are pivotally mounted for swinging movement so as to move between a viewing position and a photographing position. The reflex camera has a driving mechanism including an electric motor for causing the swing-up and -down movement of the reflex mirror and the light-blocking plate between the above-mentioned two positions, and a position-detecting device to detect the moved positions of the reflex mirror and the light blocking plate so as to control the speed of rotation of the electric motor according to the detected positions, thereby to prevent shocks and vibrations on the reflex mirror and the light-blocking plate.
