    摘要: A photographic lens device with a built-in electronic aperture-stop control system or mechanism comprising a step motor and an aperture-stop setting device which are spaced apart from each other by a suitable distance in the direction of the optical axis of the photographic lens system and are coupled to each other through a coupling means. In one embodiment, the aperture-stop control system can be incorporated in the lens device simply by slightly enlarging the diameter of the lens device or barrel without increasing its axial length because of full possible use of a heretofore unused dead space available in the lens device.

    摘要: A focus state indicator for a camera is provided such that the photographer may know a focus state in accordance with electrical signals respectively corresponding to the lens position in the previous focusing operation and a distance between a camera and a subject to be photographed. A circuit is arranged to generate a differential signal between the output electrical signals. The alarm operation of an alarm element is continuously changed between focused and out of focused states in accordance with the differential signal, so that the photographer can know the focus state.

    摘要: Image focusing device especially adapted for use in single-lens reflex cameras. A light-beam emission or projection means is incorporated in each interchangeable photographic lens in such a way that the direction of the light beam emitted or projected therefrom can be varied in response to the axial displacement of a lens group for focusing an object. The light rays which are reflected from the object and pass through the photographic lens along and in the vicinity of its optical axis are intercepted by a photodetection means disposed within a camera body, whereby whether or not the photographic lens is sharply focused at the object can be detected.

    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.
