Patent number: 7905476Abstract: A paper-sheet handling device comprises a clamp movement mechanism for sandwiching a bundle of paper-sheets by attaching component guide members to a position covering a portion of punch holes from the front and rear surfaces of the bundle of paper-sheets. A binding component is bound to the bundle of paper-sheets while contacting both tip portions of the binding component to the binding component guide members and sandwiching the bundle of paper-sheets by the clamp movement mechanism. Such a configuration enables both tip portions of the binding component to insert into each perforated hole while keeping a distance between both tip portions of the binding component and each of the perforated holes substantially constant and at the same time, even in the case of binding components of different diameters, the distance between the binding component and an internal circumference of each of the holes perforated in the bundle of paper-sheets is kept substantially constant.Type: GrantFiled: September 5, 2006Date of Patent: March 15, 2011Assignee: Max Co., Ltd.Inventor: Kiichi Haramiishi
