摘要:
A camera in which a photographing lens tube is movable between a collapsed position assumed in a non-photographing condition and an extension position assumed in a photographing condition. The camera is provided with a barrier swingingly rotatable through a hinge between a fully closed position at which the barrier covers a front surface section of a photographing lens and further to take a fully open position at which the barrier retreats from the photographing lens. The barrier is biased in a closing direction when it is in a fully closed position side relative to a substantially middle position between the fully closed position and the fully open position, while being biased in an open direction when being in a fully opening position side with respect to the substantial middle position. With a power switch being switched from its OFF state to its ON state, the barrier is shifted from the fully closed position to the fully open position in conjunction with the movement of the photographing lens tube from the collapsed position to the extension position.

A digital camera includes an outer casing cover. An open portion is formed in the outer casing cover, and an LCD unit is mounted to the open portion such that the display surface of the LCD unit is exposed to the outside through the open portion. The LCD unit includes a plate-like LCD module of a package type and a mounting frame having the LCD mounted thereto. The mounting frame is formed of a thin member such as a thin metal plate, and the holding frame for housing and holding the display element includes a display frame covering the peripheral portion of the display surface. The display surface and the display frame are exposed to the outside through the open portion of the outer casing member.

A camera whose body is wound with a belt-like protective cover having an end detachably held by pin members thereon in such a manner as to cover a wall surface thereof. The protective cover is operative to cover and protects at least a photographing lens, a distance measuring or range finder window and a stroboscopic window. Thus, the camera is put into an enclosed state. Further, the enclosed state, in which the protective cover is wound around the body of the camera, is maintained by fitting a magnet hook attached to the other end of the protective cover into another magnet hook attached to the body of the camera and making these magnet hooks attracted to each other. Moreover, when putting the camera into a ready-to-photograph state, the protective cover is unwound by removing the magnet hooks from each other and opening the photographing lens and so on.

A camera has barrier supported by a rail block attached to the body of the camera and movable from a fully closed position where the barrier entirely covers the front of an imaging lens to a fully opened position where the barrier is fully retracted clear of the front of the imaging lens. At its fully closed position and fully opened position, the barrier clicks when a ball is pressed into contact with a cam formed on the rear surface of the barrier. Projection of the ball is restrained by a slip-off prevention portion of the rail block so that the barrier is not subjected to an excessive urging force. In the camera, the barrier is not subjected to an unnecessarily large urging force and is less likely to lift away from the camera. The advantage is particularly great if the barrier in use is narrower than the outer diameter of a lens barrel.

This invention is directed to a camera in which an ordinary or normal photographing image-plane size, a photographing image-plane size narrower or smaller than the normal photographing image-plane size, for example, a panoramic size, and the like are changeable, the camera comprising a back closure openable and closable with respect to a camera body, an aperture arranged between a film and a photographing lens, for regulating an exposure range corresponding to the normal photographing image-plane size, a light shielding unit arranged between the film and the photographing lens and so arranged as to be movable between a saving position where the light shielding unit is saved (i.e. spaced) from the inside of the aperture so as not to interrupt an exposure luminous flux incident upon the aperture and a projecting position where the light shielding unit projects inwardly of the aperture to interrupt a part or substantially all of the exposure luminous flux, an operating unit for assigning the narrow photographing image-plane size, a detecting unit for detecting at least one camera operating condition including a power source condition of the camera, an opening and closing condition of the back closure, a forcible rewinding condition of the film and an exposure condition to a film surface, and a drive unit for driving the exposure unit, the drive unit driving the light shielding unit to the inward-most projected position or a saved position in spite of assignment of the operating unit in accordance with an output from the detecting unit.

An image forming apparatus includes an image forming device, a sheet feeder, and a housing. The image forming device forms an image on a recording medium. The sheet feeder stores the recording medium and conveys the recording medium toward the image forming device. The housing accommodates an electrical device in the housing. The housing includes a housing body and a drawer that is drawn out from the housing body. The drawer includes a bottom plate on which the electrical device is placeable and a partition above the bottom plate on which the electrical device is placeable.

A power supply system for supplying a grid power to a building includes a power generator, a power storing device, and a power controller. The power generator generates off-grid power from a predetermined energy. The power storing device stores the grid power and the off-grid power and supplies the stored power to the building. The power controller controls consumptions of the grid power and the off-grid power. The power controller calculates predicted consumption data related to power consumed in the building and predicted generation data related to power generated by the power generator. The power controller calculates a charging-discharging schedule for the power storing device based on the predicted consumption data and the predicted generation data by formulating the charging-discharging schedule as a mixed integer programming problem.

A converging point of processing laser light is made to accurately follow a laser light irradiation surface of an object to be processed. An object to be processed 1 is irradiated with measuring laser light along a line to cut 5, astigmatism is added to a reflected light component of the measuring laser light reflected by a front face 3 of the object 1 irradiated with the measuring laser light, a displacement sensor signal corresponding to a converged light image of the reflected light component having the astigmatism added thereto is detected, and the displacement sensor signal is made to become a feedback reference value corresponding to the quantity of the reflected light component, so as to locate the converging point of the processing laser light at a predetermined position with respect to the front face 3. This allows tire converging point of the processing laser light to follow the front face 3 of the object 1 reliably and accurately even when an area exhibiting an extremely low reflectance to the measuring laser light exists in a part of the front face 3 and lowers the quantity of the reflected light component of the measuring laser light.
