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： 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.
摘要翻译： 用于照相机的自动胶片传送装置具有以下功能：（i）自动完全展开未曝光的胶片从胶卷盒或胶卷盒中并将其卷绕在卷带盘或卷轴上，以及（ii）自动重绕 每次一次曝光已经完成时，胶片进入胶卷盒或胶卷预定的长度（对应于一帧的宽度）。 因此，即使当胶片仍然装入相机时，即使将相机反复打开，曝光的框架也已经被重新放回到遮光的胶卷盒或杂志中，从而防止它们被破坏或重新曝光。 除了如上所述的第一和第二功能之外，自动胶片传送装置可以具有计数和显示卷绕在卷取卷轴或卷轴上的胶卷上的所有可曝光帧的数量的功能或能力，或剩余的 可曝光帧数。

摘要： A lens shifting device comprising a stationary cylinder having a mounting means adapted to engage with a mating means of a main body of an equipment which uses an optical lens assembly which must be shifted for focusing, an inner cylinder which is slidably fitted into the stationary cylinder and in which is securely mounted a lens group, contact members is slidable contact with the inner cylindrical surface of the stationary cylinder, one of which is interconnected with the inner cylinder coaxially, locking means adapted to cause the contact members to lock to said stationary cylinder, and expandable-and-collapsible means interconnecting between the contact members. The inner cylinder is caused to slide step by step relative to the stationary cylinder in the axial direction thereof and forward or backward by activating the locking means and the expandable-and-collapsible means by desired timing relationship. The device is very simple in construction, but highly reliable and dependable in operation.

摘要： A manual focusing camera provided with a focus detection means adapted to generate an output signal when the image of an object is sharply focused and a locking or arresting means responsive to the output signal from the focus detection means for pressing against the rear end face of the focusing ring of a photographic lens attached on the camera, thereby locking or arresting the further rotation of the focusing ring. Therefore, one can sense when the image is sharply focused. The focus detection means and locking or arresting means are very simple in construction and can be easily incorporated into the conventional cameras. Thus, positive and sharp focusing can be ensured.

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.
