PROBLEM TO BE SOLVED: To provide a binding processing device in which a bundle of sheets to be bound is not easily removed due to its thickness and in which an influence of damage caused to the sheets is small.SOLUTION: A pair of pressure surfaces for clamping and compressing a bundle of sheets are formed using convex- and concave-shaped tooth molds that engage with each other at a prescribed tooth width, and in these tooth molds, an engaging depth between a tooth tip and a tooth root has different shapes in a tooth width direction directed toward an end edge of the sheets.SELECTED DRAWING: Figure 4 |
