摘要： A camera is disclosed which is capable of winding and rewinding a film and adjusting a focal distance by use of a single motor. In the camera, the forward rotation of the motor is used to wind the film, and when the film winding operation is completed after termination of photographing, on detecting the end of the film, a torque detect mechanism switches a planetary clutch mechanism to connect the motor with a film rewinding mechanism. Thus, it is possible to perform both the film winding and rewinding operations by use of the rotation of the motor in the same direction. Also, when, with the planetary clutch mechanism connected with the film winding mechanism, the motor is rotated reversely, then the power transmission system is switched over to a focal distance varying mechanism, whereby the focal distance can be adjusted.

摘要： A drive mechanism for a zoom lens system consisting of first and second lens groups has a movable lens barrel fixedly holding the first lens and cam structure consisting of a cam member provided on the second lens group and a cam follower member on the movable lens barrel. The movable lens barrel moves forward or rearward to shift the second lens group forward or rearward relative to the first lens group along the optical axis of the zoom lens system via the cam member so as to continuously change the focal length of the zoom lens system. The cam member is mounted on the movable lens barrel to change the curve of the cam surface relative to the cam follower member only in a middle focal length range.

摘要： A device for feeding a film from a patrone in a camera, in which the film is fed by an endless caterpillar belt having pawls for engaging with film perforations. The caterpillar belt is positioned in a camera so as to match the film perforations between two film guides of the camera and is extended parallel to the film feeding direction. The caterpillar belt is driven by a set of a driving pulley and a driven pulley. The section of the pawls, taken along the film plane, is shaped to have a circular arc contour so as to contact only with the vicinity of the central portion of each film perforation.

摘要： A camera having a sprocket with a pair of cogs formed on a periphery for engaging a filmstrip having a row of perforations separated at alternate short and long intervals. The periphery is divided by the cogs into a frictional engaging section which provides frictional engagement of the periphery with the filmstrip and a mechanical engaging section which provides mechanical engagement of the cogs with the perforations. A shutter charging mechanism is operated by rotation of the sprocket driven by the filmstrip through the mechanical engagement between the filmstrip and at least part of the mechanically engaging section of the sprocket. A switch over mechanism disconnects the sprocket and the shutter mechanism in response to rewinding the filmstrip and a locking mechanism prevents reverse rotation of the sprocket in a specific position.

摘要： A water-resistant camera has a lens barrel movable toward and away from a fluid-tight camera body for selecting the position of the lens barrel between wide-angle and telephoto positions. The camera has or can be combined with an automatic air-pressure adjusting mechanism for automatically keeping the air pressure in the inner space of the camera at a substantially constant level irrespective of the position of the lens barrel between the wide-angle position and the telephoto position. Therefore, the lens barrel can smoothly be moved with respect to the camera body upon switching between the wide-angle and telephoto positions.

摘要： A liquid crystal display unit has a transmissive liquid crystal plate having a number of pixels arranged on a two-dimensional basis, on which an image is formed, and a light source unit emitting beams of light of a plurality of luminescent colors for irradiating said liquid crystal plate from back. An interface circuit receives an image signal representative of a color image to sequentially form on said liquid crystal plate a plurality of separation images in which the color image is separated in association with the plurality of luminescent colors of said light source unit. The interface circuit causes said light source unit to flash with a luminescent color associated with a separation image formed on said liquid crystal plate in synchronism with a sequential formation of the separation images onto said liquid crystal plate. Beams of light emanated from the light source unit and transmitted through the liquid crystal plate reproduce an image.

摘要： A zoom lens is comprised of a fixed barrel, an intermediate barrel coupled to the fixed barrel through helicoid screws, a movable barrel coupled to the intermediate barrel through helicoid screws, a front lens group fixedly held in the movable barrel, and a rear lens group. The position of the front lens group in the optical axis direction is always determined by the axial movement of the intermediate barrel relative to the fixed barrel and the axial movement of the movable barrel relative to the intermediate barrel. The axial position of the rear lens group is determined by the axial movement of the intermediate barrel relative to the fixed barrel and a cam surface formed in an inner periphery of the intermediate barrel. As the axial position of the cam surface within the intermediate barrel changes with the rotational position of the intermediate barrel, the rear lens group moves in the axial direction relative to the intermediate barrel during zooming. But during focusing, a hindering device is activated to hinder the rear lens group from axial movement relative to the intermediate barrel, so that the rear lens group moves by the same amount in the axial direction as the intermediate barrel independently of the cam surface.
