For this reason, since the leading end 3a of the notched piece 3 is not pushed down excessively, it is possible to prevent the notched piece 3 from being caught in the guide path 11 when the sheet 2 is extracted from the slit 12.
Further, as shown in FIG. 9, in any inclined portion (23, 24, 25), the structure is such that it is concavely curved with respect to the cutting edge from both sides of the cutting blade 20 toward the central portion side, Excessive depression of the tip 3a of the piece 3 can be prevented, and hooking can be prevented more effectively.
Then, since the cutting edge 22 of the cutting blade 20 is configured to be inclined upward from both sides toward the back wall portion 14 side, it is gradually cut from both ends of the cutting edge 22 toward the non-cutting region 4 of the sheet 2 It is possible to make the boundary between the cut piece 3 and the non-cut area 4 (i.e., the base of the cut piece 3) beautiful.

In particular, as shown in FIG. 9C, since the upper end 25a of the upward inclined portion 25 is designed to be positioned above the height of the edge portion 13 when the cutting blade 20 is pushed down, the cutting is performed. It is possible to prevent the piece 3 from being punched out, and it becomes possible to form a non-cut area 4 of a predetermined length from the end of the sheet 2.
This makes it possible to form the tongue-shaped notching piece 3 by means of the device of the punched punch construction.

The assembly of the cutting blade 20 and the base 10 is housed in the housing 30 to form the heading formation device 1 of the present embodiment.
