Abstract

PURPOSE:To prevent useless consumption of a power supply battery, by turning off the power application to a shutter opening magnet through the operation of a trigger switch. CONSTITUTION:When winding is made and a release button is pushed into, a power supply switch S1 and a release switch S2 turn on and off, respectively. Thus, a frequency division circuit FD outputs a time signal to a control circuit SC and the control circuit SC starts control. When the release switch turns on by further depressing the release button, a shutter opening magnet beta turns on. Next, the control circuit SC turns on a shutter opening magnet alpha after a prescribed time from the input of the release signal, the shutter is opened and a switch signal output circuit GC outputs a trigger signal. The control circuit SC turns off the shutter opening magnet alpha when this trigger signal is inputted. Thus, the power can be saved.
