Information introducing device of an electronic flash unit

Abstract

In an electronic flash unit capable of being coupled to a camera body including a mounting section and an operating dial which can be rotatively operated to a predetermined position to set information regarding exposure factors and can be fixed at the predetermined position, the electronic flash unit including a support member having a mounting section engageable with the mounting section of the camera body, a transmitting member displaceable to a position responding to the predetermined position of the operating dial depending upon the engagement of the two mounting sections, and an electric circuit for controlling flash light emission, there is provided converting means for converting the information into electrical signals and introducing the same into the electric circuit. The converting means includes contact sections capable of contacting each other and secured to at least two spatially different regions relatively variable in position by the displacement of the transmitting member.
