Patent number: 8322718Abstract: In a recording medium conveyer, a driver drives a feeding member and a conveying member provided downstream from the feeding member in a recording medium conveyance direction independently. A controller stops driving the feeding member when a first time period elapses after a recording medium reaches the conveying member. When a selector judges that the thickness of the recording medium identifies the recording medium as thin paper, the controller does not drive the feeding member after the controller starts driving the conveying member, and when the selector judges that the recording medium has a thickness greater than a thickness of the recording medium that identifies the recording medium as thin paper, the controller restarts driving the feeding member no later than when the controller starts driving the conveying member.Type: GrantFiled: January 21, 2011Date of Patent: December 4, 2012Assignee: Ricoh Company, Ltd.Inventors: Hiroshi Fujiwara, Mizuna Tanaka, Tomoyoshi Yamazaki, Toshikane Nishii, Kazuyoshi Kondo, Haruyuki Honda
