PURPOSE:To transmit and receive signals between a camera and a strobe without hindrance, by providing an adapter equipped with a charging completion control part, a trigger control part, a release signal part, etc. CONSTITUTION:When an aperture control circuit DA is switched to the program flash photographing mode, only an X contact closing signal is transmitted from an X contact switch of the camera to a flash trigger circuit of an electronic flash light emitting device (strobe) through the first terminal of an adapter AD. A charging completion signal and a dimming completion signal are transmitted from the strobe to the camera through the second terminal to display them and switch an exposure time control circuit, and a release signal is transmitted from the camera to the strobe to reset a dimming completion signal generating circuit. A P signal indicating a private strobe is transmitted from the camera to the strobe through the third terminal, and a stop signal to stop the light emission of the flash is transmitted similarly. Thus, signals between the camera and the strobe are transmitted and received smoothly. |
