Abstract

PURPOSE:To achieve secure exposure control by providing a speed reduction mechanism which operates on a driving plate only in exposure operation. CONSTITUTION:As an armature 3 is attracted, the locking part 7d of a driving plate 7 and the bent part 5a of a control lever 5 are disengaged from each other to move the driving plate 7 to right by a spring 9, and a shutter opening/closing lever 15 turns counterclockwise accordingly to turn a shutter blade 13 counterclockwise around a supporting shaft 14, thereby starting exposure. At this time, a cam part 7e provided to the driving plate 7 displaces a pin 61a fixed to a sector gear 61, which is turned counterclockwise, so an escape wheel 64 and an anchor 66 operate a governor to reduce the speed of the driving plate 7, so that the opening speed of the shutter blade 13 is decreased.
