BINDING APPARATUS AND PAPER STAPLE

摘要

A binding apparatus includes a cutter portion having a pair of cutter blades, a table having a drawing hole through which the cutter portion can be inserted, and a lower pressing member disposed below the drawing hole. Each of the cutter blades includes a thin-walled portion, a thick-walled portion formed below the thin-walled portion, and an inclined face formed between the thin-walled portion and the thick-walled portion. The cutter portion holds a paper staple between the thin-walled portions, and penetrates through a stack of sheets that is placed on the table when the cutter portion is moved down. The inclined faces pushes and folds respective leg portions of the paper staple in a direction in which the leg portions becomes close to each other. The lower pressing member folds and presses the leg portions of the paper staple by relatively moving up with respect to the table.
