摘要： A shifter is equipped with a rack and a stopper. A transmission gear transmits power from an electric motor to the rack. A retention pin extends vertically downward from the transmission gear. When the shifter slides to an origin, the retention pin locks the stopper, which causes the electric motor to step out. On detecting the step-out of the electric motor, the position control device recognizes that the shifter has reached the origin (the reference position) and has been fixed at the position, thus setting the shifter position.

摘要： When forming an image, if there are not enough sheets remaining in a paper feed cassette to satisfy the image forming request, the image forming operation is not executed, and along with prompting the user to refill the paper, the paper feed cassette is pushed out towards an uninstalled state. The apparatus waits for a paper refill, and begins the image forming operation after that paper refill.

摘要： A roller turning force generator is connected to a driving gear which is mounted on a shaft. The shaft is connected to offset roller assemblies disposed in an offset mechanism via connecting gears. The offset roller assemblies rotatably supported inside the offset mechanism are turned by a driving force transmitted from the roller turning force generator to discharge individual sheets of a printing medium in a sheet transport direction. The offset mechanism is linked to an offsetting force generator so that the offset mechanism can be shifted along a direction perpendicular to the sheet transport direction.

摘要： A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.

摘要： A multicolor electrophotography apparatus and method wherein a photoconductive copy sheet surface containing uniform electric charge is exposed to an original through light filter which enables one color to be recorded, is developed with colored toner to produce a copy of that color, and the sequence is repeated for each of the other colors, utilizing superimposing toner images on the same copy sheet. In a preferred embodiment a sheet carriage is adapted to hold the copy sheet at its upper edge portion and carry it only in a certain direction for example in a vertical direction whereas a developer bed on which a plurality of developer reservoirs, each containing different colored developer toners are mounted, is adapted to travel in the other direction for example in the horizontal direction. During travel of the sheet carriage in the vertical direction, the photosensitive copy sheet passes through a charge deposition station, an exposure station and a development station thereby accomplishing reproduction of an image of one specified color. These steps may be repeated in as many colors as desired, for example, with accompanying movement of the developer bed so as to position the succeeding developer reservoirs containing different colored toners in the path of the sheet carriage, to produce, in as many colors as desired, a composite color image.
