Abstract
PURPOSE:To make a magnet smaller along with realization of power saving by returning with return means an armature to a position on this side by a stated distance of a position where a shutter claw can be acted when power supply to a coil is intercepted. CONSTITUTION:A plate spring 5 with weak elasticity, return means for armature returning, made of nonmagnetic material such as phosphor bronze, is fixed to an armature 4 with spot welding. Further, stopper 6 of the armature 4 for a curtain is one that defines adjustably a return position of the armature by the plate spring 5 and driving of the curtain is prescribed of the curtain is prescribed with an actuating pin 7 prepared on a claw for a curtain. Further an armature for a rear curtain is held rotatably with an axis on an axis 10 provided on one side of a yoke of the coil 8 of a magnet for a rear curtain through the process, it is possible to make suction type magnet smaller and to control the shutter with a small quantity of current consumption.
