自動露出カメラ。 a power source, a photometric circuit connected to the power source, an electromagnetic coil connected to the power source for starting a closing operation of the shutter, and a switching element for cutting off current to the electromagnetic coil in accordance with an output of the photometric circuit; transmitting a back electromotive force generated in the electromagnetic coil when power to the electromagnetic coil is cut off to the flash discharge tube device as a dimming signal for stopping light emission of the automatically dimming type flash discharge tube device; A connection terminal for a dimming signal is inserted between the electromagnetic coil and the connection terminal for a dimming signal, and when it receives an output from the charging circuit of the flash discharge tube device, it becomes conductive and occurs in the electromagnetic coil. It allows the back electromotive force to be transmitted to the dimming signal connection terminal, and when there is no output from the charging circuit, it is in a non-conducting state and the back electromotive force is transmitted to the dimming signal connection terminal. An automatic exposure camera characterized by being provided with a gate circuit that prevents.
