  • Patent number: 7469894
    Abstract: An image forming apparatus which conveys a sheet to a nip portion between an intermediate transfer belt and a secondary transfer out-roller to record an image includes a sheet conveying device which conveys the sheet to the nip portion, a CCD line sensor which detects a sheet size in a sheet width direction perpendicular to a conveyance direction of the sheet, and a transfer-side regulating device which is arranged near the nip portion and regulates the width direction of the conveyed sheet. The transfer-side regulating device can move the nip portion to a position where the width direction of the conveyed sheet is regulated based on a detection result obtained by the CCD line sensor.

  • Publication number: 20080159784
    Abstract: An image forming apparatus includes a rotating member, a driving force transmission unit configured to transmit drive force to the rotating member, a drive unit configured to rotationally drive the rotating member via the driving force transmission unit, a detecting unit configured to detect a velocity of the rotating member and generate velocity data based in the detected velocity, and a control unit configured to control the drive unit based on the velocity data. The control unit calculates a correction value to be added to a drive velocity instruction value so as to cancel velocity variation of velocity data during one rotation of the rotating member, and a correction value is controlled so as to eliminate a difference between a correction drive instruction value obtained by adding a correction value to a drive velocity instruction value and the drive velocity instruction value.

  • Publication number: 20070195217
    Abstract: An intermediate portion of a low voltage power supply wire is extinguished by irradiation of a laser beam to form a wire cut portion. A different potential portion serves as the wire cut portion of the low voltage power supply wire. The distance between the end portions of a high voltage power supply wire and the low voltage power supply wire between which the potential is different is increased. An electrical short-circuit between the high voltage power supply wire and the low voltage power supply wire hardly occurs. Even when impurities invade into the gap between an insulating layer on the high voltage power supply wire and the low voltage power supply wire and a glass substrate, electrode corrosion of the high voltage power supply wire and the low voltage power supply wire can be prevented. A display failure can be prevented.

  • Patent number: 6957037
    Abstract: This present invention provides an image reading apparatus aiming at improving its operability while saving the cost and an image forming apparatus provided with the same. Sponges for pressing a pressing plate against a platen glass are constituted of nine sponges. Then, restoration forces Fa to Fc generated when sponges on a front side of a document feeding apparatus far from a fulcrum shaft of a hinge unit are crushed are set smaller than restoration forces Fg to Fi generated when sponges on a deep side of the document feeding apparatus near the fulcrum shaft 45 of the hinge unit are crushed.
