Abstract

PURPOSE: To achieve the simplification of the mounting member of a dimming type flash device by making combined use of a transmission line for synchronizing signal also for a transmission line for photographing mode changeover signals.
CONSTITUTION: The dimming type flash device F has a synchronizing signal electrode Fx and ground electrode Fe and the camera C has an assigned aperture signal electrode Cav, photographing mode changeover signal electrode Ctv, synchronizing signal electrode Cx and ground electrode Ce. The attachment A for connecting both is provided with the electrodes Ax1, Ax2, Aav, Atv, Ae1, Ae2 corresponding to the respective electrodes, the electrodes Aav and Atv being held connected. The attachment A generates the photographing mode changeover signal for changing photographing mode to flash mode and the assigned aperture signal from the circuit formed by transistor 34, etc. In this way, the combination use of the transmission line for synchronizing signal and the transmission line for photographing mode changeover signal permits the simplification of the mounting members of the flash device.
