Abstract

PURPOSE:To enable control over a leading curtain and a trailing curtain, to simplify constitution, and to reduce power consumption, by providing a switch coupling with a member which sets time or bulb photographing. CONSTITUTION:When a shutter-speed setting dial is set in a bulb or timer position, a trailing curtain is locked mechanically and a switch S2 is opened. When a shutter release button is depressed sufficiently, switches S1 and S2 are both turned on to feed electricity to a magnet Mg1, and a mirror is elevated; and a lens is stopped down to a shooting aperture and a leading curtain runs. When the shutter release button is freed in bulb photographic mode, the trailing curtain is unlocked in interlocking with the said operation to run, thereby performing exposure. Further, the S1 is also turned off to stop feeding electricity to a control circuit A1.
