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

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: 9359158Abstract: A sheet feeding device includes: a sheet stacking member; an air blowing unit configured to blow air onto the sheet bundle placed on the sheet stacking member to suspend multiple sheets of the sheet bundle; a lifting/lowering unit configured to lift/lower the sheet stacking member; an optical reflection sensor configured to detect a suspended sheet suspended by the air blowing unit; and a control unit configured to control the lifting/lowering unit based on an output value of the optical reflection sensor. The optical reflection sensor is configured to be capable of detecting an area corresponding to multiple sheets in a sheet suspension zone extending between a non-suspended sheet bundle and a conveying member configured to convey an uppermost sheet of the multiple suspended sheets. The non-suspended sheet bundle is made up of sheets not suspended during a period when air is blown by the air blowing unit.Type: GrantFiled: December 11, 2014Date of Patent: June 7, 2016Assignee: RICOH COMPANY, LIMITEDInventors: Yasunori Hino, Chikara Akata, Tomoki Tamate, Hideaki Takahashi, Munehisa Fuda, Toshihiro Okutsu, Takashi Fukumoto, Yasuo Niikura, Masaki Ishizaki, Kiyotake Nakamura, Hidetoshi Kojima, Hisayoshi Sugawara, Kazunori Konno, Tatsuya Sugawara, Kohjiroh Haga, Masato Hashimoto
