Patent number: 6478294Abstract: A sheet feeding device includes a feeding roller that is driven to rotate, and a base plate to stack sheets thereupon. The sheet feeding device is configured to rotate around a supporting axis thereof in directions to contact and separate from the feeding roller. A base plate pressing member is configured to press the base plate toward the feeding roller, such that an uppermost sheet of the stack of sheets stacked on the base plate contacts the feeding roller in order to be fed by the feeding roller. A first friction device is arranged in a vicinity of a first part of an upper surface of the base plate so as to oppose the feeding roller. The first friction device is configured to provide a bottom sheet of the stack of sheets stacked on the base plate with a first frictional resistance greater than a predetermined value.Type: GrantFiled: April 6, 2001Date of Patent: November 12, 2002Assignee: Ricoh Company, Ltd.Inventor: Kenji Hiratani

Patent number: 5484140Abstract: A catch type sheet tray for accommodating sheets sequentially driven out of an image forming apparatus by catching the leading edges of the sheets. The tray has a transport unit for transporting the sheet driven out through the outlet downward. A holder receives the sheet conveyed by the transport unit by catching the leading edge of the sheet while causing the trailing edge of the sheet to hand down to the outside. A mounting section mounts the transport unit on a portion of the apparatus from which the horizontal tray has been removed. The catch type tray is mounted on the apparatus in place of the horizontal tray.Type: GrantFiled: November 9, 1993Date of Patent: January 16, 1996Assignee: Ricoh Company, Ltd.Inventors: Hiroshi Hirose, Kenji Hiratani, Masashi Kimijima
