Publication number: 20110248442Abstract: A banknote processing apparatus according to the present invention includes a banknote separating and feeding portion which separates, from banknotes, one feed-out banknote closest to a banknote holding portion, and feeds out the feed-out banknote. The banknote separating and feeding portion includes a feed roller, a separating roller, a kick-on roller, and auxiliary rollers. The auxiliary rollers are positioned on an opposite side of the kick-on roller from the feed roller, protrude onto the banknote pressing portion side beyond the banknote holding surface, and contact with the feed-out banknote. Each of the auxiliary rollers has a plurality of large diameter portions formed intermittently in a circumferential direction of the auxiliary roller. The auxiliary rollers are positioned on the same axis and apart from each other such that phases of mutually adjacent auxiliary rollers in a rotation direction of the auxiliary rollers are offset from each other.Type: ApplicationFiled: April 11, 2011Publication date: October 13, 2011Inventors: Yoshiyuki KATO, Tomohisa Oe

Patent number: 7980544Abstract: A sheet hold flap 18 is arranged on an upper side of a vicinity of a rear end portion of a sheet table 7 to which a sheet is continuously supplied from a copier or the like. The sheet hold flap is switched to an upper initial position and a sheet holding position by a solenoid 17. There is carried out a control of holding a rear end portion of a sheet P by driving the sheet hold flap to the sheet holding position after taking in a sheet to the sheet table and returning the sheet hold flap to the initial position to escape from a sheet path in taking in a successive sheet. Sheet jamming by floating up the sheet is prevented by holding a sheet on the sheet table until immediately before taking in the successive sheet.Type: GrantFiled: August 12, 2005Date of Patent: July 19, 2011Assignee: Max Co., Ltd.Inventors: Kazuaki Baba, Atsushi Kurabayashi, Toru Yoshie
