Patent number: 8876102Abstract: In one embodiment, a supply mechanism is provided. The supply mechanism supplies accumulated paper sheets to a takeout position sequentially. A takeout belt having adsorption hole runs along a surface of the takeout position. An opening of a negative pressure chamber is arranged so as to face the takeout belt. A suction unit sucks air existing at the takeout position via the opening and the adsorption holes. The suction unit causes a negative pressure to act on each of the paper sheets so that each is adsorbed onto an adsorption surface of the takeout belt. The suction unit has an air supply port to supply air into the negative pressure chamber. The air supply port is arranged so that the air supplied via the air supply port is directed to a position and in a direction different from those of the opening.Type: GrantFiled: June 2, 2010Date of Patent: November 4, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Toru Todoriki, Yusuke Mitsuya, Yoshihiko Naruoka, Yukio Asari

Patent number: 8157256Abstract: A sheet handling apparatus is provided that includes a take-out member to take out a sheet from a take-out position by rotating the sheet in a state in which negative pressure is applied to the sheet and the sheet is adsorbed to the take-out member. A conveyor portion receives and conveys the taken out sheet by the take-out member and a control portion controls the take-out member such that, when the sheet at the take-out position is being adsorbed to the take-out member, the take-out member is rotated at a circumferential speed that is slower than a conveying speed of the sheet at the conveyor portion. In addition, when the sheet adsorbed to the take-out member is being transferred to the conveyor portion, the take-out member is rotated at a circumferential speed that is the same as a conveying speed of the conveyor portion at that time.Type: GrantFiled: February 2, 2011Date of Patent: April 17, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Yusuke Mitsuya, Yoshihiko Naruoka, Toru Todoriki, Yukio Asari, Naruaki Hiramitsu
