Patent number: 10518992Abstract: A sheet conveying device includes a sheet loader, a loader elevating device, a sheet presence detector to detect a sheet on the sheet loader, and circuitry configured to determine whether the bundle of sheets is loaded on the sheet loader based on a detection result of the sheet presence detector and to control movement of the loader elevating device. The circuitry is configured to cause the loader elevating device to lift the sheet loader to a second position in response to a detection result of the sheet presence detector indicating absence of the sheet on the sheet loader at a first position and not to determine absence of the sheet when the circuitry causes the loader elevating device to lower the sheet loader from the second position to the first position after the circuitry causes the loader elevating device to lift the sheet loader to the second position.Type: GrantFiled: November 6, 2018Date of Patent: December 31, 2019Assignee: Ricoh Company, Ltd.Inventors: Yousuke Edo, Hikaru Fukasawa, Hidetoshi Kojima

Patent number: 10513404Abstract: A sheet-material supply device includes a lift, a sheet-material detector, and a sheet-material retaining conveyor. The lift elevates sheet materials in a stacked state. The sheet-material detector detects that an uppermost sheet material of the sheet materials in the stacked state has reached a predetermined height. The sheet-material retaining conveyor retains and conveys the uppermost sheet material that has reached the predetermined height. The sheet-material supply device stops elevation of the sheet materials in the stacked state when the sheet-material detector detects that the uppermost sheet material has reached the predetermined height. The sheet-material retaining conveyor is disposed to be movable in a direction in which the sheet materials in the stacked state elevate.Type: GrantFiled: December 9, 2016Date of Patent: December 24, 2019Assignee: RICOH COMPANY, LTD.Inventors: Takeshi Akai, Hidehiko Fujiwara, Yasuo Niikura, Yousuke Edo, Satoru Takano, Yasunori Hino, Tadashi Matsuoka, Atsunori Yoshida, Ryo Kanno, Hikaru Fukasawa

Patent number: 10442643Abstract: A sheet feeding device, which is included in an image forming apparatus, includes a reference face, a sheet loader, an air blowing device, an air drawing device, and a conveying body. The reference face stands upwardly at a downstream side of a sheet conveying direction. The sheet loader includes a body and a leading end disposed downstream from the body in the sheet conveying direction. The sheet loader moves upwardly to a position where the leading end rotates downwardly to the body. The air blowing device blows air toward a sheet bundle loaded on the sheet loader and lift an uppermost sheet of the sheet bundle. The air drawing device is configured to draw the uppermost sheet. The conveying body conveys the uppermost sheet in the sheet conveying direction while the uppermost sheet is in contact with the air drawing device due to attraction by air.Type: GrantFiled: October 31, 2017Date of Patent: October 15, 2019Assignee: RICOH COMPANY, LTD.Inventor: Yousuke Edo

Sheet-member separation device, sheet-member separation method, program, and image forming apparatus
Patent number: 10384897Abstract: A sheet-member separation device includes a first air blower, an attractor, a conveyor, a second air blower, and an adjuster. The first air blower blows air onto a front side of a stack of sheet members in a sheet-member conveyance direction. The attractor attracts an uppermost sheet member floated from the stack of sheet members by the air blown from the first air blower. The conveyor conveys, in the sheet-member conveyance direction, the sheet member attracted by the attractor. The second air blower blows air toward a lateral side of the sheet member. The adjuster moves the second air blower and the attractor together to adjust positions of the second air blower and the attractor in the sheet-member conveyance direction.Type: GrantFiled: December 13, 2016Date of Patent: August 20, 2019Assignee: Ricoh Company, Ltd.Inventors: Satoru Takano, Hidehiko Fujiwara, Takeshi Akai, Yasuo Niikura, Yousuke Edo, Yasunori Hino, Tadashi Matsuoka, Atsunori Yoshida, Ryo Kanno, Hikaru Fukasawa -

Patent number: 8955835Abstract: In the invention, after the last sheet is conveyed from a paper feed tray, the paper feed tray is lifted up so that the paper feed tray is brought into contact with a suction belt. An elastic cleaning member that removes paper particles, or the like, is installed at an area of the paper feed tray where the paper feed tray is in contact with the suction belt. The suction belt is driven while the cleaning member is in contact with the suction belt. The paper particles, or the like, removed from the suction belt by the cleaning member are collected in a paper-particle collecting device from a vacuum chamber via a vacuum duct.Type: GrantFiled: November 13, 2013Date of Patent: February 17, 2015Assignee: Ricoh Company, LimitedInventors: Hideyuki Satoh, Masaki Ishizaki, Yousuke Edo, Takaya Ochiai
