Title
(DE) KAMERA UND KAMERAZUBEHÖR
(EN) CAMERA AND CAMERA ACCESSORY
(FR) APPAREIL PHOTOGRAPHIQUE ET ACCESSOIRE D'APPAREIL PHOTOGRAPHIQUE
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.
(FR) La présente invention concerne l'appareil photographique suivant. Selon l'invention, une première broche de contact côté appareil photographique est une broche correspondant à une détection d'une variation de signal provoquée par le couplage d'un accessoire d'appareil photographique. Une deuxième broche de contact côté appareil photographique est une broche correspondant à l'alimentation en courant permettant une communication avec l'accessoire d'appareil photographique couplé. Une troisième broche de contact côté appareil photographique est une broche correspondant à l'application d'une force d'entraînement à un actionneur de l'accessoire d'appareil photographique. Les première, deuxième et troisième broches de contact côté appareil photographique sont agencées de sorte que, lorsque le montage côté appareil photographique passe d'un premier état à un second état, la troisième broche de contact côté appareil photographique contacte des première et deuxième surfaces de contact côté accessoire, la deuxième broche de contact côté appareil photographique contacte la première surface de contact côté accessoire et la première broche de contact côté appareil photographique ne contacte pas les deuxième et troisième surfaces de contact côté accessoire.
