Title
(EN) Camera and camera accessory
(ZH) 相机及相机配件
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.
(ZH) 本发明提供如下的相机。第一相机侧触针是与相机配件的联接引起的信号变化的检测对应的针。第二相机侧触针是与和联接的相机配件通信用的电源供给对应的针。第三相机侧触针是与用于将驱动力供给到相机配件的致动器对应的针。第一相机侧触针、第二相机侧触针和第三相机侧触针以如下方式布置:当相机侧安装件从第一状态向第二状态切换时,第三相机侧触针与第一配件侧触点面和第二配件侧触点面接触,第二相机侧触针与第一配件侧触点面接触,且第一相机侧触针不与第二配件侧触点面和第三配件侧触点面接触。
