Patent number: 8474807Abstract: A conveying device that conveys a sheet bundle with a flattened back-face portion includes a first conveying unit, a driving unit, and a second conveying unit. The first conveying unit retracts to a position where no driving force is exerted on the sheet bundle before a leading end of the sheet bundle formed in a flat spine shape enters, and abuts on the sheet bundle to exert conveying force after the leading end of the sheet bundle passes a conveying position. The driving unit moves the first conveying unit to retract to the position and to abut on the sheet bundle. The second conveying unit is positioned on an upstream side of the first conveying unit in a sheet bundle conveying direction and conveys the sheet bundle towards the first conveying unit.Type: GrantFiled: June 27, 2012Date of Patent: July 2, 2013Assignee: Ricoh Company, LimitedInventors: Shinji Asami, Nobuyoshi Suzuki, Naohiro Kikkawa, Kazuhiro Kobayashi, Tomohiro Furuhashi, Kiichiroh Gotoh
