Abstract
In a camera having both a mechanical release and a motor drive release, the motor drive unit is provided with a cam which, when the motor drive unit is actuated, limits the movement of the mechanical release member to an amount sufficient only to trip a motor energizing switch without mechanically releasing the curtains. In this way, the same release lever can be used for both the mechanical and motor drive release operations.
