ABSTRACT:
A monocular reflex camera having a viewfinder mirror and carrier assembly movable between a viewing position of the camera and an exposure taking position comprises a pivoted crank arm of which the pivot shaft is articulated connected with the mirror carrier close to the centre of gravity. The carrier has a lateral stop lug arrange at a distance from the pivot shaft and protruding into the path of the movement of the crank arm. A spring urges the stop lug into abutment with the crank arm. Stops are provided for locating said mirror assembly in the exposure taking position, and also in the viewfinding position. During the viewing position of the mirror and over a substantial portion of its travel into the exposure taking position, the lug is maintained in engagement with said crank arm by said spring and on arrival at the picture taking position the lug disengages the crank arm against the action of the spring.
