Description

[Detailed Description of the Invention] This invention relates to a punching jig for punching holes in non-perforated cards and sheets of paper for binding into loose-leaf notebooks.

Loose-leaf notebooks originally use only special loose-leaf paper.

The same goes for loose-leaf ledgers.

Therefore, in the past, the only use was to purchase loose-leaf paper and write on it.

However, recently there has been a noticeable trend among students to use large cards, such as B6 size cards, in place of notebooks or for collecting materials.

This type of card has holes (8cm intervals).
On the other hand, thick non-perforated cards are also sold in large quantities, and sometimes it becomes necessary to bind these non-perforated cards.

To make a hole for binding in a blank card or sheet of paper, fold the card or sheet of paper in half, find its center position, align this center position with the center alignment part of the punch, and then punch the hole. However, it is not preferable to fold the card or paper sheet in half because the card is thick, and the work becomes troublesome when only a one-hole punch is available.

This invention was devised in view of this point, and is intended to make it possible to easily punch holes in cards or paper products with simple operations even in such cases.

Hereinafter, one embodiment of this invention will be explained with reference to FIGS. 1 to 3. Reference numeral 1 is a drilling jig, in which plates 2 and 3 of the same size are stacked one on top of the other, and one edge of the holes is made with an appropriate thickness. They are joined together with a band-shaped spacer 4 having a shape interposed therebetween, so as to create a state as if a single plate had been folded back.

Thereby, a card or sheet of paper having a thickness corresponding to the thickness of the spacer 4 can be sandwiched between the plates 2 and 3.

One of the two plates 2 and 3 of this drilling jig 1 is considerably thicker than the other plate 3, and has sufficient strength. .

One edge of this plate 3 is provided with protrusions 5 at both ends thereof.

The protruding portion 5 may be formed in the shape of the plate 2, or may be formed as a separate member and attached to the back surface of the plate 2.

Holes 6 and 7 of the same size are provided in a state in which holes 6 and 7 of the same size are overlapped in the plate body 2.degree.3 which is bound at one edge with a spacer 4 in between.

This drilling jig 1 configured in this way has plate bodies 2 and 3.
A card (or sheet of paper) is inserted between the holes, and this is inserted into the groove 9 of the punch 8 as shown in FIG. 4, and one edge of the punch 8 is pressed against the protrusion 5 for use.

When the lever 10 of the punch 8 is pushed down in this state, the punching blade advances from the hole 7 of the plate 3 toward the hole 6 of the plate 2. paper sheets) will be perforated.

Next, shift the punch 8, press the other edge against the protrusion 5 on the other side, and punch 9 holes again.

Figure 5 shows a card 12 with holes 11 made in this way.
shows.

Note that among the three holes 11, the one in the center will be drilled twice.

The one shown in FIG. 6 is for four holes.

In this case, by shifting the punch 8 and operating it twice, it is possible to make four holes in the card by punching two holes at a time.

Since this device is constructed as described above, the positioning of the punch during punching can be easily and reliably performed, so that it is extremely easy to position the punch for loose-leaf notes at the correct position on any card or sheet of paper. The advantage is that you can drill holes.
