Abstract

PURPOSE:To surely prevent malfunction, by providing a inhibiting member inhibiting the release of a tightening member at nonphotographing and holding the inhibiting member so that it does not inhibit the tightening of the member at photographying. CONSTITUTION:When a camera is charged to a photographing preparation completion state, a locking section 44a of a locking lever 44 is coupled with an armature 3, and a tightening lever 5 is not turned against the spring force of a spring 6 even if a shock is given to the camera, and an AF controlling plate 22 and a driving plate 7 operating a shutter switching lever 15 do not start movement. When a release plate 40 is depressed by a shutter button, a pin 40d is moved by a cam surface 40a of the release plate 40 and a locking lever 44 turns clockwise. Thus, a locking section 40d releases the engagement with the armature 3 and is shunted to a position not interfering the operation of the armature 3.
