    摘要: In an automatic focusing apparatus which detects sharpness signals from high-frequency components of brightness signals contained in video signals from video cameras and which stops a focusing lens of the video camera at a position at which its peak value is obtained, the movement of the focusing lens is started by detecting received light signal levels by performing projection-reception operations with a specified amount of infrared light and detecting their variations with a received light signal level detector or with a micro-computer. Furthermore, depending upon the focal depth of the focusing lens, priority is given to processing of distance information based on sharpness signals or distance information determined by the infrared light projection-reception operation in the lens driving controller for performing the focusing operation. According to the automatic focusing apparatus of the present invention, movement of the lens only due to variations of contrasts can be avoided, and stable image pictures are thus obtainable. Also, the most suitable focusing operation mode for a particular focal depth of a lens in use can be selected.

    摘要: An automatic film transport device for use in cameras has a first function of (i) automatically completely unrolling an unexposed film from a film case or magazine and winding it on a take-up reel or spool and a second function of (ii) automatically rewinding the film into the film case or magazine by a predetermined length (corresponding to the width of one frame) each time one exposure has been completed. Therefore, even when one erratically opens the camera back when the film is still loaded in the camera, the exposed frames have been already rewound into the light-shielded film case or magazine, so that they may be prevented from being ruined or reexposed. In addition to the first and second functions as described above, the automatic film transport device may be provided with a function or capability of counting and displaying the number of all exposable frames on the film wound on the take-up reel or spool or the remaining number of exposable frames.

    摘要: A drive device for a lens barrel and a diaphragm shutter is disclosed. The drive device of this invention comprises a stepping motor including a stator and rotors. The stator is constituted by a plurality of stator members disposed around a lens barrel, each having a bifurcate portion around which a conductor is wound, and the bifurcate portions are disposed in face-to-face relationship with each other with a predetermined space being interposed therebetween. The rotors are respectively disposed in the predetermined spaces. The driving forces of the rotors are independently transmitted at least to the lens barrel including a photographic lens element and to a diaphragm shutter.
