Abstract

PURPOSE:To surely prevent malfunction, by storing a tightening member to an operable state at photographing, with a control member controlling the photographing operation of a camera through the start of operation with the released tightening member. CONSTITUTION:When a camera is charged to a photographing preparation completion state, since a locking section 44a of a locking lever 44 is engaged with an armature 3, even if a shock is given to the camera, since a tightening lever 5 does not turn against the spring force of a spring 6, an operating plate 7 does not start movement for an AF controlling plate 22 and a shutter switching lever 15. In this state, when a release plate 40 is depressed by a shutter button, a pin 40d is moved by a cam surface 40a of the plate 40 and the 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.
