    • The disclosed single lens reflex camera includes a shutter dial and a pentaprism as well as an eyepiece, and forms an image of a scene in the camera's field of view and a data image near the scene image through the eyepiece by passing data light from the vicinity of the pentaprism into the interior of the pentaprism. A display switchover device includes a transmission arrangement on the shutter dial for transmitting the motion of the dial, a linkage arrangement engageable with the transmission arrangement to be actuated on the basis of the selected position of the shutter dial, and a display selector between the pentaprism and the eyepiece and actuated by the linkage arrangement to control the direction of the data light to the eyepiece. According to an embodiment, the selector includes a subprism having a surface from which the data light from the pentaprism is reflected and another surface for directing the data light to the eyepiece, and a reflector that faces the two subprism surfaces for changing the reflecting position in response to the linkage arrangement.
    • 所公开的单镜头反光相机包括快门拨盘和五棱镜以及目镜,并通过目镜的数据光通过目镜形成摄像机的视野中的场景的图像和场景图像附近的数据图像 五棱镜进入五棱镜的内部。 一种显示切换装置,包括:用于传送表盘运动的快门表盘上的传动装置;可根据所述快门盘选择的位置使所述传动装置啮合的连杆装置;以及五棱镜之间的显示选择器 和目镜,并由联动装置致动以控制到目镜的数据光的方向。 根据实施例,选择器包括具有来自五棱镜的数据光被反射的表面和用于将数据光引导到目镜的另一表面的面,以及面向两个子表面的反射器,用于改变反射位置的反射位置 响应联动安排。
