Further, since the cutting blade 22 for forming the perforation descends while sliding on the guide path 11 and cuts the sheet 2 in cooperation with the edge portion 13 of the base, it is linear, curved, By adopting unit blades with various cutting edge shapes such as pipes, it is possible to form perforations of design lines.

That is, depending on the arrangement of the perforation blades of the perforation creating cutting blade 22, as shown in FIG. 10 (a), the heading forming instrument 101 for creating the heading portion 1 having a design pattern can be used. As shown in FIG. 10B, a headline forming instrument 102 for creating a rectangular headline portion 1 can be used.
Further, as shown in FIG. 10C, the perforation cutting blade 22 may be a cutting blade for making a cut line, instead of a perforating blade for making a hole.

By simply pressing down the cutting blade while the sheet is in contact with the guide section, it is possible to provide perforations with a fixed shape in place, so that you can use the notebook you are familiar with as a system notebook for schedule management with a good appearance. It becomes possible to remake.
The guide portion of the present invention may have any configuration as long as the corners can be fixed by abutting adjacent edges of the sheet 2 and may be formed at any portion. For example, the columnar guide portions 23a and 23b may be eliminated, and two wall surfaces adjacent to each other at a right angle may be formed in the slit. Moreover, it is good also as only the guide part 33 provided in the housing 30, and it is good also as only the columnar guide parts 23a and 23b in a slit.

Next, the configuration of a headline forming instrument 200 according to the second embodiment of the present invention will be described with reference to FIG.
This headline forming instrument 200 is for forming the headline part 1 with the cut piece 4. In addition to the perforated cut blade 22, a cut blade 25 for creating the cut piece is provided at the cutting edge of the cut blade 20. This is different from that of the first embodiment. Hereinafter, only a difference from the headline forming instrument 100 of the first embodiment will be described, and the description of the members having the same configuration will be omitted by giving the same reference numerals.

As shown in FIG. 12, the cutting blade 25 for creating the cut piece is disposed between the perforating blades 22 a, 22 b... For forming the perforation, and has a cross-sectional shape corresponding to the shape of the cut piece 4. It has become.
The cutting blade 25 for creating the cut piece is also inserted in the guide path 16 parallel to the guide path 11 of the punching blade 22, and the sheet 2 is attached to the tongue piece 17 at the edge portion 17 where the guide path 16 and the slit 12 intersect. It is designed to cut into a shape.
By cutting the cut piece 4 formed by the cut piece creating cut blade 25 and projecting it from the edge of the sheet 2, the headline portion 1 with high visibility can be formed.

Hereinafter, the structure of the cutting blade 25 for creating a cut piece will be described with reference to FIG.
The cutting edge of the cut piece creating cut blade 25 has a structure in which cut top portions 27 are provided on both sides via a downward inclined portion 26 inclined downward from the insertion portion side of the slit 12 toward both sides.

Perforated scraps drilled as the perforation 3 are discharged from the discharge port 38.

The portion of the cut piece 4 of the heading portion 1 created in this way is bent, and the tip is projected outward from the corner of the sheet (see FIG. 13C).
This makes it possible to form a heading portion protruding from the end of the book without using a special member such as an index seal.
When the heading 1 is no longer necessary, it can be manually cut along the perforation 3 (see FIG. 13D).

The cutting blade 25 for creating cut pieces according to the present embodiment has a blade edge structure provided with cut tops 27 on both sides, so that the sheet is cut from the both sides of the blade edge toward the insertion port. Without being limited to the configuration, for example, a structure in which a cut top is provided at the distal end on the insertion port side may be employed.
Further, in this embodiment, the cutting edge of the cutting blade is inclined upward from both side portions toward the back wall portion side, and the upper end of the upward inclined portion is more than the base edge portion when the cutting blade is pushed down. By being designed to be positioned above, it was gradually cut from the both ends of the blade edge toward the non-cut region of the sheet, but without being inclined, for example, by providing a step, the cut piece It is also possible to make the boundary between the non-cut region clear.

Further, as shown in FIG. 14, a cut blade 22 for perforation formed by arranging a plurality of unit blades is disposed between the first and second contact portions 23a and 23b, and a cut piece is formed. In the case where the cutting blade 25 is provided, an elastic member 60 for returning the tongue-shaped tip portion (that is, the tip region 4 a of the cutting piece 4) cut by the cutting piece creation cutting blade 25 into the slit 12. May be provided on the bottom surface of the housing 30b.
The elastic member 60 may be a sponge or urethane material provided with a blade receiving plate on its upper surface, and as shown in FIG. 15, the elastic member 60 has a size that fits inside the cut blade 25 for creating a cut piece. The leaf spring 70 may be provided on the base 10.

  In this case, the leaf spring 70 is inclined slightly downward from the rear wall portion 14 so that the insertion and removal of the sheet 2 can be smoothly guided, and the position 71 corresponds to the top portion 27 of the cutting edge of the cutting blade 25 for creating the cut piece. A shape that is gently curved so as to be the highest is preferable. As a result, the tip region 4a of the cut piece 4 is pushed back into the slit 12, and the sheet 2 can be smoothly taken in and out.
