<p>A movable blade provided with a circular edge (10) for cutting the corner (102) of the paper (1) and a straight edge (11) for cutting the corner edge (101) is inserted in a movable blade inserting hole provided in the stationary blade, and the corner (102) of the paper (1) inserted in a slit is cut between the stationary edge, and the circular edge (10) and the straight edge (11). Thereby, during the cutting of the corner (102) by the straight edge (11), both of the circular edge (10) and the straight edge (11) cut the corner (102), the corner (102) is cut in the state of being tensioned between the circular edge (10) and the straight edge (11), as if the corner edge (101) is held by the straight edge (11), thereby, the bite of the paper is disappeared to be handled easily and an uneven alignment of the cut corners is diminished. <IMAGE></p> |
