20130154178 | SHEET PROCESSING APPARATUS, IMAGE FORMING SYSTEM, AND SHEET PROCESSING METHOD - A sheet processing apparatus performs predetermined processing on a sheet or a sheet bundle. The sheet processing apparatus includes: a conveying unit that conveys a sheet along a conveying path; an aligning unit that, each time a sheet is conveyed by the conveying unit, aligns the sheet; a stacking unit that reverses a conveying direction of a sheet to convey the sheet backward to a branch path branched from the conveying path, and stacks the sheet in the branch path; and a binding unit that binds a sheet bundle aligned by the aligning unit, in the conveying path. | 06-20-2013 |
20130264762 | SHEET PROCESSING APPARATUS AND IMAGE FORMING SYSTEM - A sheet processing apparatus includes a stacking channel to stack multiple sheets into a sheet bundle, and a binding device to bind together the sheet bundle, the binding device including multiple clamping portions to clamp the sheet bundle to create multiple clamping marks on the sheet bundle. When the binding device binds a corner area of the sheet bundle, a longitudinal direction of each of the multiple clamping marks forms an angle within a range from 30 degrees to 60 degrees with a side of the corner area of the sheet bundle. | 10-10-2013 |
20130270762 | SHEET PROCESSING APPARATUS AND IMAGE FORMING SYSTEM - A sheet processing apparatus includes a conveyance unit to transport a sheet bundle including multiple sheets in a sheet conveyance direction and a binding device including a clamping unit. The clamping unit includes multiple projections and multiple recesses to engage the respective projections to clamp the sheet bundle inserted therebetween. At least one of the multiple projections includes an inclined portion facing a sheet conveyance direction, and an inclination of the inclined portion is 45 degrees or smaller relative to a face parallel to the sheet conveyance direction. | 10-17-2013 |
20130300050 | SHEET PROCESSING APPARATUS, IMAGE FORMING SYSTEM, AND SHEET BINDING METHOD - A sheet processing apparatus includes a pair of squeezing members having a projection and a recess to engage each other, to squeeze a sheet bundle inserted therebetween in a direction of thickness of the sheet bundle, and a pressure applying unit to apply pressing force to the squeezing members to squeeze and bind the sheet bundle. The pressing force generated between the squeezing members by the pressure applying unit increases in strength as a relative distance between the squeezing members decreases. | 11-14-2013 |
20140138896 | SHEET PROCESSING APPARATUS AND IMAGE FORMING SYSTEM - According to an aspect of an embodiment, a sheet processing apparatus includes: a conveying unit configured to convey sheets; a stacking unit configured to stack the conveyed sheets to form a sheet stack; and a binding unit configured to include a pair of toothed jaw and bind the sheet stack by pressing the sheet stack between the pair of toothed jaw, wherein at least one portion of edges of the toothed jaw is rounded. | 05-22-2014 |
20140151951 | POSTPROCESSING APPARATUS, AND IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM INCLUDING THE POSTPROCESSING APPARATUS - A postprocessing apparatus includes a stacking unit that stacks a sheet, an abutting unit that corrects a conveying direction of the sheet, a return roller that abuts the sheet against the abutting unit, a shift conveying unit that shifts the sheet in a width direction, and a width direction detector that detects a width direction position of the sheet. When the sheet is shifted by the shift conveying unit by a predetermined amount, passed to the return roller, and abutted against the abutting unit, distances A and B are nearly the same, where the distance A is a distance from a conveying direction position of a side of the sheet to a rear end of the sheet and the distance B is a distance from the return roller to the abutting unit. | 06-05-2014 |
20140219747 | SHEET BINDING DEVICE, SHEET PROCESSING APPARATUS, IMAGE FORMING APPARATUS, IMAGE FORMING SYSTEM, AND SHEET BINDING METHOD - A sheet binding device binds a sheet bundle by causing a movable-crimping-member moving unit to move a movable crimping member thereby holding a sheet bundle between crimping members. The movable-crimping-member moving unit includes: a link mechanism that includes a first link member rotatably connected to the movable crimping member, a second link member rotatably connected to a fixed member fixed to a device body and connected to the first link member through a connecting part; a connecting member rotatably connected to the connecting part, and capable of moving between a first position causing the link mechanism to be extended and a second position causing the link mechanism to be more flexed than in the first position; and a connecting-member moving unit that includes a rotary member capable of rotating on a displaceable rotating shaft, and reciprocates the connecting member by rotation of the rotary member in one direction. | 08-07-2014 |
20150030414 | METHOD FOR ATTACHING CRIMPING MEMBERS, SHEET BINDING DEVICE, AND IMAGE FORMING APPARATUS - The present invention is concerning a method for attaching a pair of crimping members in a sheet binding device that binds a sheet bundle by engagement of the pair of crimping members, wherein at least one of the crimping members is attached to a member to which the one of the crimping members is to be attached in a state where the pair of crimping members is in engagement. | 01-29-2015 |
20150076759 | SHEET BINDING DEVICE, SHEET PROCESSING APPARATUS, AND IMAGE FORMING SYSTEM - A sheet binding device includes: a pair of crimping members each including alternately-arranged multiple recesses and multiple protrusions to bind a sheaf of sheets by fitting the recesses and the protrusions with the sheet sheaf interposed therebetween. When the recesses and the protrusions of the pair of crimping members are fitted, slanted side faces of the protrusions of one of the pair of crimping members and that of the other one of the pair of crimping members are in contact with each other with a clearance left both between top portions of the protrusions of the one of the crimping members and bottom portions of the recesses of the other one of the crimping members and between top portions of the protrusions of the other one of the crimping members and bottom portions of the recesses of the one of the crimping members. | 03-19-2015 |
