<p>PURPOSE:To exhibit the lighting effect of multiple flash photography by transmitting a charge completion signal to a camera when a charge completion signal regarding all flash devices is generated. CONSTITUTION:Channels 2a, 2b, and 2c each have a circuit 7 which generates a connection detection signal when flash devices A, B, or C, i.e. corresponding device is connected, a circuit 3 which receives a charge completion signal from the flash device, and a circuit 5 which generates a coincidence signal when supplied with the connection detection signal and charge completion signal, or not supplied with the connection detection signal. Consequently, a multiple flash adapter device F transmits the charge completion signal to the camera body G when all capacitors of the connected flash devices A, B, and C are charged completely.</p> |
