Title:
FORM PROCESSING DEVICE, AUTOMATIC FORM PROCESSING DEVICE, AND IMAGE FORMATION APPARATUS
Document Type and Number:
Japanese Patent JP2014177319
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a crimp type form binding device capable of stably giving strong binding strength to a form bundle with simple constitution.SOLUTION: Uneven tooth patterns 50, 60 have tooth faces of their teeth 51, 61 formed partially of elastic bodies 80. When crimp binding is carried out by meshing the teeth 51, 61 of the pair of uneven tooth patterns 50, 60, the elastic bodies 80 formed on the tooth faces of the teeth 51, 61 which are crimped together deform in conformity with tooth face shapes of the other teeth. Then even if a gap or shift is made in the engagement between the teeth 51, 61 owing to decreases in processing precision and assembly precision of the teeth 51, 61, the elastic bodies 80 deform in conformity with the tooth face shapes. Consequently, the crimp binding can be performed with wide area without any clearance so as to obtain strong form binding force.
