Abstract

PURPOSE:To always obtain a proper exposure, by constituting so that an external flash device emits light only when a photographing distance exceeds a prescribed distance. CONSTITUTION:A synchro terminal 2 is connected in parallel to a synchro contact 7 of a main electronic flash device 1 through a switch 5. Accordingly, when a shutter button is pushed, the synchro contact 7 is closed, but in this case, when the switch 5 is conductive, both terminals of the synchro terminal 2 conduct by synchronizing with the synchro contact 7, by which a synchronizing signal for synchronizing light emission of an external flash device is sent out from the synchro terminal 2 as a conduction signal.
