ABSTRACT:
Apparatus for positioning a movable member, the apparatus comprising a driving shaft, a driven shaft and a clutch for engaging and disengaging the driving shaft and the driven shaft. The circumferential surface of a cam fixed around the driven shaft has such a specified angle of an arc whose center is the axis of the driven shaft that the movable member is prevented from shifting the position due to inertia rotation of the cam and the driven shaft.
