Publication number: 20110266743Abstract: A sheet feeder includes: a housing; a sheet feeding mechanism and a manual feed tray and that is mounted pivotably to the housing. The manual feed tray can assume a first posture that is closed relative to the housing, and a second posture that is open relative to the housing. A link couples the housing with the manual feed tray and pivots with a pivoting movement of the manual feed tray to hold the second posture of the manual feed tray. A posture changing mechanism permits the manual feed tray to pivot farther in an opening direction from the second posture when a load acts on a sheet mounting surface and causes the manual feed tray to assume a third posture while being held by the link. A posture holding mechanism holds the third posture of the manual feed tray.Type: ApplicationFiled: April 26, 2011Publication date: November 3, 2011Applicant: KYOCERA MITA CORPORATIONInventor: Kiyonori Yamamoto

Patent number: 7831173Abstract: An image forming apparatus has an image bearing member and a main body with an internal conveyance path for conveying a transfer material. An opening/closing member is attached to the main body and is displaceable between a closed position and an opened position where the conveyance path is exposed. A cover is set to cover a part of the image bearing member facing the conveyance path when the opening/closing member is open and is retracted from the conveyance path when the opening/closing member is closed. A moving mechanism slides the cover. Front and rear frames are held movably by the moving mechanism and are attached respectively to front and rear edges of the cover in a sliding direction. A tension applying mechanism acts on the frames to apply tension to the cover in the sliding direction during a sliding movement of the cover.Type: GrantFiled: March 19, 2008Date of Patent: November 9, 2010Assignee: Kyocera Mita CorporationInventors: Takashi Kusukawa, Kiyonori Yamamoto

Patent number: 5517294Abstract: An image-forming machine comprising a rotary drum and a cleaning means which removes the toner remaining on the peripheral surface of the rotary drum. The cleaning means includes a support member that extends in the direction of center axis of the rotary drum, a blade-holding member that is mounted on the upper surface of the support member and extends in the direction of center axis of the rotary drum, and a cleaning blade that is held by the blade-holding means and extends in the direction of center axis of the rotary drum. The blade-holding member is allowed to swing on the swing axis that extends in a plane which is substantially perpendicular to the center axis of the rotary drum. An acute angle .alpha. is defined between the cleaning blade and a tangential line of the drum at a portion where the front end of the cleaning blade that is pushed comes into contact with the peripheral surface of the rotary drum, on the downstream side as viewed in a direction in which the rotary drum rotates.Type: GrantFiled: August 29, 1995Date of Patent: May 14, 1996Assignee: Mita Industrial Co., LtdInventors: Tadakazu Ogiri, Kiyonori Yamamoto, Masahiko Kobayashi, Naoki Motobayashi, Hiroshi Ishida
