Abstract

PURPOSE:To obtain a photographing mode switching information suitable for cameras of various types, by providing a control signal circuit for supplying a control signal generated in a trigger signal terminal of an electronic flash device body, to a control signal terminal of a camera body. CONSTITUTION:A minus terminal 7a connected to an earth contact terminal (b) of a flash device body is connected to a minus terminal 8a, and also a repeating terminal 7c connected to a trigger contact terminal (a) is connected to a repeating terminal 8b through a diode 31. When voltage causing by the completion of electric charge of a capacitor 14 is generated in the terminal (a), a transistor 34 conducts, and a controlling circuit which is not shown in the figure, of a camera body is electrified through a control signal terminal 8c, and is switched to a flash photographing mode. When an adaptor provided with said trigger signal transferring circuit and control signal circuit is installed to the flash device body, it can be used so as to be suitable for cameras of various types.
