ABSTRACT:
A lens shutter for a quick-return single-lens reflex camera in which the diaphragm blades and shutter blades are operated by an operating ring driven rotationally in opposite directions by a driving device. The driving device has a pair of axially biased rods that coact to sequence their travel axially in two directions for driving the operating ring through gear racks on one of the rods and a driving ring coupled to the operating ring. A pinion meshes with both gear racks. A stop lever releasably locked by a signal lever stops the operating ring temporarily during taking of an exposure and the signal lever releases the stop lever at the end of an exposure which it signals or indicates. A cocking mechanism comprising a plurality of levers cocks the operating rods to cock the shutter.
