First, the rear end portion 8c of the presser lever 8 is pushed down, then the paper piece bundle 10 is placed on the upper surface of the mounting table 1, and the front end portion of the paper piece bundle is positioned below the paper piece presser cutting blade 15. At this time, the front end surface of the sheet bundle is brought into contact with the front end portion 3a of the bracket to align the front end surface. After that, when the rear end portion 8c of the pressing lever is opened, the blade tip of the paper piece pressing cutting blade 15 presses the upper surface of the paper piece bundle 10 by the elasticity of the torsion spring 7. At this time, the blade edge of the paper piece pressing cutting blade 15 cuts into several sheets (about 2 to 3 sheets) on the upper surface side of the sheet piece bundle 10. In this state, pulling the paper pieces of the paper piece bundle 10 one by one from the upper surface in the length direction (to the right in FIG. 1), the paper pieces are beautifully cut by the pressing blade 15, and the paper pieces are cut beautifully. The bundle 10 is pulled away.

When the cutting ability of the presser cutting blade 15 that is holding the bundle of paper pieces 10 deteriorates, the fixing screw 11 of the safety hood 9 is removed, the safety hood 9 is opened upward, and then the presser foot is pressed. With the lever rear end 8c pushed down, for example, with a suitable receiving member placed under the press lever tip 8b, loosen the set screw 16 of the paper piece pressing unit 13 and pull out the support cylinder 14 to the front (positioning projection). Draw out until part 17 comes out of the depression on the presser lever 8 side). After that, the support cylinder 14 is rotated to direct the next new piece of paper pressing blade 15 downward, the positioning convex portion 17 of the support cylinder 14 is again inserted into the concave portion on the pressing lever 8 side, and fixed by the fixing screw 16. When all the paper piece presser cutting blades 15 have been used, the paper piece presser unit 13 is replaced with a new one.
