Document Type and Number:
Japanese Patent JP2014162106
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sheet processing device that is constituted to prevent occurrence of warpage in both sides of a position of performing binding processing during deep-drawing by an uneven crimping teeth so as to prevent conveyance abnormality and decrease in loading quantity.SOLUTION: A sheet processing device 3, which performs binding processing by pressurizing and deforming unevenly a part of a sheet bundle in which a plurality of sheets are stacked, comprises a plurality of crimping teeth 101 and 102 that are plurally arranged for the uneven deformation and can be engaged with each other. In the crimping teeth 101 and 102, tooth widths in a direction orthogonal to the direction of the arrangement, of clamping teeth positioned in at least one sides 101A2 and 102A2 of end portions in the direction of the arrangement are set smaller than the tooth widths of crimping teeth 101A1 and 102A1 at the middle in the direction of the arrangement.
