摘要：
An electroflash controlling circuit wherein, in order to make the fully open time of a shutter and the flashing time of a flash accurately coincide with each other, a delaying circuit operated by an electric signal for starting a shutter blade opening motion or an electric signal for starting a shutter blade closing motion is provided so that a flashing circuit may be triggered after the lapse of a delay time made by the delaying circuit.
