In the figure, reference numeral 41 denotes a spring that always acts to draw the shaft body 38 toward the support body 11 side.

However, the present invention is constructed as described above, and as shown in FIG. The movable member 17 is moved up and down with respect to the support body 11 by rotation of the rotating shaft 4 by energization, and a large number of holes are punched in one side of a piece of paper etc. inserted into the paper piece insertion groove 10 by the first punching blade 12. , a small number of holes are punched by the second punching blade 13.

First, when drilling 30 holes with the first punching blade 12, as shown in the imaginary line in FIG. The through hole 28 is opened to the guide (L26), and the central protrusion 35 of the block body 30.30H is engaged with the cam surface 36a of the cam plate 36, and the block body 30, 303 By closing all the through holes 27 that open to the guide holes 26, all the punching blades 12 move up and down together with the movable member 17 to punch 30 holes.

At this time), due to the engagement of the lock bodies 30, 30a and the cam surface 36a of the cam plate 36, the operating body 31 operates as shown by the arrow in FIG. The first link member 34, which moves and engages with the back side of this cam plate 36, swings around the shaft body 33, and the shaft body 38 moves rearward against the elastic force of the spring 41. As the body 38 moves, the adjustment piece 40 retreats from the paper insertion groove 10.

In addition, when drilling 26 holes with the first drilling blade,
By moving the block bodies 30, 302 relatively toward the center in the direction in which the first punching blades 12 are arranged, and opening only two through holes 27 on both outer sides to the guide holes 26, 26 holes can be drilled. In addition, when making 20 holes with this first punching blade 12, the block bodies 30, 301 are moved further toward the center to open all the through holes 27 to the guide holes 26, thereby making 20 holes. It is possible to make a hole in the hole.

Next, when drilling two holes with the second punching blade 13, as shown in FIGS. 2 and 8, the guide shaft 29 moves the block bodies 30, 30a relative to the center in the direction in which the punching blades 13 are arranged. Move the block bodies 30, 30a and the cam plate 3.
By releasing the engagement state with the cam surface 36a of 6, the operating body 31 operates as shown by the arrow in FIG.
8 is moved forward by the elastic force of the spring 41, and as the shaft body 38 moves, the adjustment piece 40 advances into the paper piece insertion groove 10 between the punching blades 12 and 13, and then By closing the through hole 28 opening into the guide hole 26 with the central protrusion 35 of the block body 30, 302, drilling can be performed using only the two punching blades 13.

The number of perforations can be easily selected by providing a display board on which the predetermined number of perforations is written on the support body 1 and by providing a pointer on either one of the blocks 30, 30a.

As described above, according to the present invention, the insertion amount of the paper piece can be adjusted by moving the adjustment piece into and out of the paper piece insertion groove, and the plurality of first perforations provided in parallel on the support body can be made by moving the block body. By selecting the blade and a small number of second perforating blades, it is possible to selectively perform a large number of holes and a small number of holes with one perforation machine, and furthermore, the adjustment piece can be used to make paper strip insertion grooves. By regulating the amount of paper strips inserted into the paper strip, the distance from the inserting edge of the paper strip to the hole can be set constant, and the positions of the holes punched in the paper strip will not be irregular from hole to hole. .

Moreover, by interposing the operating body between the block body and the adjustment piece, the selection operation of the punching blade by the block body and the adjustment operation of the paper strip and the insertion amount by the adjustment piece are simultaneously connected. Therefore, the selection operation between drilling a large number of holes and drilling a small number of holes can be performed quickly and easily.
