Title
(EN) CAMERA AND CAMERA ACCESSORY
Abstract
(EN) The present invention provides the following camera. A first camera side contact pin is a pin corresponding to detection of a signal change caused by coupling of a camera accessory. A second camera side contact pin is a pin corresponding to supply of power for communication with the coupled camera accessory. A third camera side contact pin is a pin corresponding to supply of a driving force to an actuator of the camera accessory. The first second and third camera side contact pins are disposed in such a manner that when a camera side mount shifts from a first state to a second state the third camera side contact pin contacts first and second accessory side contact surfaces the second camera side contact pin contacts the first accessory side contact surface and the first camera side contact pin does not contact the second and third accessory side contact surfaces.
