Patent number: 6773005Abstract: A sheet post-processing apparatus includes a head portion for driving a staple into a sheet bundle, an anvil portion opposingly arranged to the head portion for receiving and bending the staple driven from the head portion, a feeding device for feeding the sheet bundle between the head portion and the anvil portion, a fixed guide member extending laterally and immovably positioned between the head portion and the anvil portion for guiding the sheet bundle, and an auxiliary guide member disposed on an upstream side of the fixed guide member in a sheet bundle feed direction of the sheet bundle fed by the feeding device. The auxiliary guide member projects from the fixed guide member to lead the sheet bundle to the fixed guide member without touching a leading edge of the sheet bundle fed by the feeding device on an upstream edge of the fixed guide member in the sheet bundle feed direction.Type: GrantFiled: October 27, 2003Date of Patent: August 10, 2004Assignee: Nisca CorporationInventors: Kouki Sato, Koichi Kitta

Patent number: 6641024Abstract: A stapling device for automatically binding a set of sheets is formed of a needle driving unit for driving a needle in the set of the sheets; a bending unit for bending the driven needle; two pairs of front and rear guide shafts for supporting the needle driving unit and the bending unit and guiding movements of these units in a sheet width direction; and moving shafts for moving these units along the guide shafts in the sheet width direction. By disposing each moving shaft between the front and rear guide shafts, each unit can be moved in the sheet width direction stably and smoothly, and the entire device can be structured small. Also, in at least one of the units, a small space is formed for a moving mechanism for at least one of needle driving device and bending device in a sheet thickness direction, to thereby achieve a further miniaturization of the entire device.Type: GrantFiled: February 5, 2001Date of Patent: November 4, 2003Assignee: Nisca CorporationInventors: Kouki Sato, Toshiro Fukasawa, Koichi Kitta

Patent number: 6607188Abstract: A sheet post-processing apparatus includes a head portion for driving a staple into a sheet bundle and having a base portion and an attachment portion detachable from the base portion; an anvil portion arranged to face the head portion for receiving and bending the staple driven from the head portion; a head portion support member for engaging and supporting the base portion of the head portion; and an anvil portion support member for supporting the anvil portion. A moving device relatively moves the head portion, the anvil portion and the sheet bundle along surfaces of the sheet bundle placed at a stitching position between the head portion and the anvil portion.Type: GrantFiled: October 29, 2001Date of Patent: August 19, 2003Assignee: Nisca CorporationInventors: Kouki Sato, Koichi Kitta

Patent number: 5662318Abstract: A stapler capable of stapling one or more stapling portions of a sheaf of sheets to be bound with only one movable staple driver in a corner binding manner, one-side binding manner or doublespread binding manner regardless of the width and length of the sheets is applicable to a sheet handling device such as a copying machine and printer to compose a sheet-binding system. The staple driver and clinching means with an anvil for bending the staple into a non-returnable state are connected by a connecting member formed in a substantially U-shape so as to satisfactorily receive the sheets to be stapled.Type: GrantFiled: August 7, 1995Date of Patent: September 2, 1997Assignee: Nisca CorporationInventors: Takeshi Harada, Koichi Kitta
