摘要： In a page printer, a gate roller, a developing unit, a photo-sensitive drum unit, a fixing unit and a sheet discharging roller are mounted on the open front side of a housing body in the order stated from above, thus forming a substantially vertical sheet conveying path. As a result, the installation floor area is reduced. In the rear portion of the housing, and a transferring unit and a sheet guide member are provided on the cover of the housing body. Thus, the light beam generating unit and the photo-sensitive drum are maintained unchanged in position at all times. A cut sheet feeder is mounted over the housing body so that it is movable back and forth, thus facilitating the inspection and maintenance of the printer.

摘要： A page printer having a housing body and including a gate roller, a developing unit, a photo-sensitive drum unit, a fixing unit and a sheet discharging roller arranged on the front side of the housing body in the order stated from above so that the printing sheet conveying path is substantially vertical to reduce floor area required for installation. An optical writing unit is provided on the rear side of the housing body. Guide members are provided on the housing body to readily mount or demount the photo-sensitive drum unit. Further, a shield board is disposed between the photo-sensitive drum unit and the fixing unit so that the printing sheet will not be stained by toner scattering from the photo-sensitive drum.

摘要： An image forming apparatus employing a face-down delivery system in which the plane of the recording medium at any position relative to any other position assumed by the recording medium beginning with a stacking tray and ending with a delivery tray does not exceed 90.degree.. The apparatus includes a detachable cartridge which includes a photosensitive member, a charging device and a cleaning device. In one preferred embodiment, register rollers and fixing rollers are positioned relative to each other such that a substantially zero angular deviation exists in the path traveled by the recording medium between these two pairs of rollers.

摘要： An electrophotographic recording apparatus comprising these units which are arranged vertically: a sheet feeder for feeding a sheet of recording paper to a sheet feed inlet; an image forming unit for forming a printing image onto a photosensitive drum based on printing data and transferring the printing image onto the sheet; and a fixing unit for fixing the transferred image on the sheet. The apparatus further comprises a sheet switching guide mechanism by which the head end of the sheet is switched to both upper and lower directions. When the sheet switching guide mechanism is set to the upper direction, the printed sheet is forwarded by a sheet guide member to thereby pass through the printing path the sheet has already been through with the rear side of the sheet being the front, and the printing data is written from the last line during this process.

摘要： An ultra-thin wristwatch utilizes a liquid crystal display cell operable by a single electrochemical cell without the use of a voltage booster. Through the use of an extremely small piezoelectric tuning fork vibrator and electronic circuitry consisting of a C-MOS, it becomes possible to manufacture a movement having a thickness less than 5 mm.
