摘要： A motion picture camera provided with an automatic focusing device is arranged to have an image of light emitted from an infrared ray emitting diode projected toward an object to be photographed, and to detect an in-focus state by detecting a peak value of output voltage from a light sensitive element as the direction of the emitted light is varied by a rotatable distance measuring cam. The automatic focusing device is adapted for a zoom lens assembly and is arranged to drive an imaging lens, supported by a shaft which is guided by plate shaped masks at both ends of the lens assembly, in the direction of the lens optical axis. The force for driving the imaging lens is kept low, so that the imaging lens can be accurately adjusted by a rotatable focusing cam during a focusing operation. The rotational position of the distance measuring cam, and that of the focusing cam, are provided in the form of resistance values which vary according to the cam lifts, or in the form of digital codes. When digital codes are employed, distance intervals are established so that the depth of field at each interval overlaps an adjacent interval. Satisfactory focusing thus is provided for all distances within any measured interval.
摘要翻译：设置有自动对焦装置的电影摄像机被配置为使从红外线发射二极管发射的光朝向要拍摄的物体投射的光，并且通过检测来自于被摄体的输出电压的峰值来检测对焦状态作为发射光的方向的光敏元件由可旋转距离测量凸轮变化。自动对焦装置适用于变焦透镜组件，并且被布置成沿着透镜光轴的方向驱动被由透镜组件的两端的板状掩模引导的轴支撑的成像透镜。用于驱动成像透镜的力保持较低，使得在聚焦操作期间可以通过可旋转聚焦凸轮精确地调整成像透镜。距离测量凸轮的旋转位置和聚焦凸轮的旋转位置以根据凸轮升降机或以数字代码的形式而变化的电阻值的形式提供。当采用数字代码时，建立距离间隔，使得每个间隔的景深与相邻间隔重叠。在任何测量间隔内为所有距离提供满意的聚焦。

摘要： A self-timer for cinecameras wherein an electric delay circuit is used for detecting a length of time from the release to the commencement of a photographing process which takes place with an electric power having been actually supplied to a film feeding motor. The amount of the rotation made by the film feeding motor from the start of the rotation of the motor is either mechanically or electrically detected. When the detected amount of rotation reaches a preset value corresponding to a number of frames of the film required for self-timer photographing, the motor is stopped to terminate the photographing operation, so that the photographing operation with the self-timer can be accomplished exactly for a preset number of frames.

摘要： An information displaying apparatus includes, bundles of optical fibers with their ends coplanar and disposed in line. A movable masking member imposes information on the light input to the fiber array. At the output end, information markings are selectively illuminated or otherwise luminously designated to display various kinds of information. Displaying means may be disposed within a view finder or on the outer casing of a camera. An artificial light source operates to provide light through the masking member and may be switched on manually or automatically when needed for information display.
