摘要： A single lens reflex camera is provided with a photocell so positioned in the camera as to receive thereon light incident through the lens and reflected onto the photocell by the mirror. During each photographing operation, the mirror is pivotally elevated so that the incident light is no longer received by the photocell. The camera electronics monitors the photocell output which is representative of the magnitude of light received by the photocell and, unless a relatively rapid change in photocell output is detected during a photographing operation, an alarm is actuated to indicate failure of the mirror to properly pivot.
摘要翻译：单个镜头反光相机设置有光电池，其定位在相机中以便在其上接收通过透镜入射的光并通过反射镜反射到光电池上。在每次拍摄操作期间，镜子被枢转地升高，使得入射光不再被光电池接收。相机电子设备监控光电管输出，其代表由光电池接收的光的大小，并且除非在拍摄操作期间检测到光电池输出的相对快速的变化，否则启动报警以指示反射镜的故障正确枢转。

摘要： An automatic film winding device for camera comprising the film winding member of which the outer peripheral portion at one end is formed larger in diameter than the other outer peripheral portion. The automatic film winding device for camera comprises a pressing means mounted on a camera body for pressing the narrowed leading end of the film against the outer peripheral surface of the film winding member at the position where the leading end of the film is received into the film winding chamber. The pressing means is so set that its pressing position corresponds to a part of the cut edge of the narrowed leading end portion of the film, and mounted on the inner surface of a back cover and urged by spring means so as to be capable of pressing the leading end of the film to the film winding member in the winding operation.
摘要翻译：一种用于照相机的自动胶片卷绕装置，其包括其一端的外周部分的直径大于其它外周部分的膜卷绕部件。该照相机自动胶片卷绕装置包括一个安装在照相机主体上的按压装置，用于将胶片卷绕部件的外端表面在薄膜的前端接收到薄膜的位置处挤压薄膜的前端卷绕室。按压装置被设定成使其按压位置对应于薄膜前端部的狭窄端部的切割边缘的一部分，并且安装在后盖的内表面上并且由弹簧装置推压以能够按压胶卷的前端在卷绕装置上卷绕成卷。

摘要： An improved sprocket wheel for substantially planar feeding of a strip of film in a photographic camera by applying a thrust to end edges of two parallel and spaced apart rows of perforations provided along the film strip includes two corresponding trains of film feeding teeth, each tooth having a curved film thrusting surface confronting the plane along which film is fed in the camera and comprising a base portion having a gentler slope with respect to the film feeding plane than an involute tooth profile and an upper portion having a steeper slope with respect to the film feeding plane than an involute tooth profile, and further having a ridge defined between the outer side surface and the film thrusting surface of each tooth to substantially conform to a rounded corner of each film performation and thereby facilitate smooth feeding of the film.
