  • Patent number: 6263185
    Abstract: An image forming apparatus with a scanner for reading image information from a document. The image forming apparatus includes a scanner section, an image forming section, a sheet discharging section, a sheet stacking section, a sheet finishing section, and a relaying section. The scanner section is configured to read image information of a document that can then be formed into an image in the image forming section. Exemplary options include an image forming apparatus with a scanner mounted on the apparatus body above the image forming section.

  • Patent number: 6134418
    Abstract: An image forming apparatus of the type having a sheet discharging section provided in an upper portion of a body of the apparatus, a stacking section for stacking a sheet driven out via the sheet discharging section, and a casing accommodating a sheet conveying mechanism. An inclined surface is formed on top of the stacking section and inclines obliquely downward toward the sheet discharge section. A guide on the bottom of the casing is used for sliding against the inclined surface when the casing is mounted to the body of the apparatus.

  • Patent number: 6112047
    Abstract: An image forming apparatus of the type having a sheet transport path extending substantially vertically upward from a sheet feed section to a sheet discharge section is disclosed. The apparatus allows different kinds of finishers to be mounted thereto without lessening the advantages particular to the substantially vertical path configuration. A relay unit intervenes between the sheet discharge section and the finisher. A sheet jamming the relay unit or the sheet discharge section during usual sheet discharge mode operation can be removed with ease.

  • Patent number: 5083169
    Abstract: A device for removing deposits from the surface of a photoconductive element which is installed in an electrophotographic copier, facsimile machine, printer or similar image recorder. A rotatable fur-brush is movable into contact with the photoconductive element for removing deposits from the latter. The fur-brush is supported by an arm which is angularly movable between an operative position and an inoperative position assigned to the fur-brush. The arm is in turn driven by a pressing lever. When the image recorder is to start on a copying operation, the deposit removing operation is interrupted immediately. In a further embodiment, the fur-brush may also be movable in a reciprocating motion in the axial direction.

  • Patent number: 4914480
    Abstract: A corona discharging device of the type using a wire and for use with an electrophotographic copier or similar apparatus which effects an electrostatic process. Any of end blocks which are located at opposite ends of a shield case and made of an insulating material accommodates therein a conductive member in the form of a spring which is connected to a corona wire. A generally hollow cylindrical end block cover is made of an insulating material and configured to surround at least that part of the end block in which the spring is disposed. The end block cover is slid on and along the outer periphery of the end block along the axis of the cover into and out of engagement with the end block. The device may serve as a charger for charging a photoconductive element, a discharger for discharging it, or a precleaning discharger of a cleaning unit.
