Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a perforated paper that is perforated.

Various types of paper are used in copying machines or computer output devices depending on the purpose. Perforated paper is paper that has been subjected to perforation processing, and is used for, for example, the following purposes.

■Admission ticket An admission ticket used for events, etc., containing a set of tickets such as coffee tickets and souvenir exchange tickets, which is used for items that are set as one ticket and must be separated from each other.

It is used when multiple tickets are set into one, such as the same number of tickets on a 0-ticket bus.

■Slip This is used when multiple related slips, such as slips affixed to products and delivery slips, are copied onto one sheet, such as department store delivery slips created by some types of copying machines.

FIG. 1 shows an example of conventionally used perforated paper. The perforated paper 1 has perforation lines 21. ~23 are provided. In each of the perforation lines 21 to 23, for example, perforations (elongated cuts 113) having a length of 2n are arranged on the Ichimaro line alternately with uncut portions 4 having a length of 2n. When cutting a specific perforation line on perforated paper, first select that line, pinch it with both hands, and then pull it in the direction of cutting. In places such as department stores during busy periods, where paper is cut into thick pieces in a short time, the selection of the perforation line for cutting may be incorrect, resulting in cutting off parts of the paper that are not needed by that department. The same was true for work performed by inexperienced workers.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide perforated paper that allows a necessary portion of the paper to be cut out simply by pulling both ends of the paper.

The present invention achieves the above-mentioned object by varying the tensile strength of the perforation lines formed on the paper.

The present invention will be described in detail with reference to Examples below.

FIG. 2 shows a miniature perforated sheet with three perforation lines spaced at equal intervals. The first perforation line 61 of the perforated paper 5 is such that perforations 71 having a length of 211 are arranged in a straight line alternately with uncut portions 8 having a length of 2 m.

Further, the second perforation line 62 has perforations 72 having a length of 311 arranged alternately with the above-described uncut portions 8 on a - straight line. Furthermore, the third perforation line 6
3, perforations 73 having a length of 4n are arranged alternately with the uncut portions 8 on a - straight line.

A slip or the like that needs to be perforated at the initial stage is copied onto the paper section cam which is cut off by the third perforation line 63 of the perforated paper 5.

Second perforation line 62 and third perforation line 63
A slip or the like that needs to be separated in the next step is copied onto the paper portion B that is separated by the following steps. On the sheet portion C to be separated by the first perforation line 61 and the second perforation line 62, a slip or the like that needs to be separated in the next step is copied. On the remaining sheet of paper, in the final step, a copy of a slip or a series of slips is copied. It goes without saying that these copies onto the perforation-treated paper 5 are performed all at once using an original created in advance to match the perforation format.

The table below shows the relationship between the length of the perforation and the tensile strength until the perforation line is cut when perforations are made on a copy sheet cut to a width of 4 CI. However, the lengths of the perforations and the uncut portions of the perforations are both 2 n, and it is assumed that there are no perforations at either end of the paper.

As shown in the table, the longer the perforation length, the weaker the tensile strength until the perforation line is cut.

[If you hold both ends (paper portion A and paper portion D) of the perforated paper 5 after copying and pull it in the direction of spreading it, the third perforation line 63 will be cut first, and the paper portion A will be cut. is separated from other parts. The tensile strength required for this separation is approximately equal to or less than the value in the table for the same paper as in the table above when the perforated paper 5 is locally grasped and pulled with fingers. . The separated paper portion A is used in the department where the separation was performed.

When the next department receives the remaining portion of the perforated sheet, it holds both ends (sheet portion B and sheet portion D) and similarly pulls it. The second perforation line 62 is thereby cut, separating paper portion B from the other portions.

Furthermore, in the next department, both ends of the remaining paper portion (paper portion C
and the paper portion D) and pull it to cut the first perforation line 61. As a result, the paper portion C and the paper portion are separated.

As described above, each department can obtain the required paper portion by simply pulling both ends of the perforated paper.

FIG. 3 shows perforated paper sheets in which the length of the uncut portion at the perforation line is varied. The perforated paper 9 has perforations 11 each having a length of 2n.
Three perforation lines 121 to 123 are provided. In the first perforation line 121, perforation 1
The dark non-cutting part 13 of No. 1 is set to 211, and the
At the third perforation lines 122 and 123, the uncut portions 13 are set to 3n and 1, respectively.

In this perforated paper 9, the third perforation line 1
23 is cut first, followed by the first perforation line 12
1 is cut, and finally the second perforation line 122 is cut.

Various perforation lines 61~63°121~
123 can be realized by preparing a plurality of sets of tooth profiles of a processing machine that creates perforations. Of course, the interval and shape of the perforation lines should be set arbitrarily depending on the content to be copied or printed, and from this point of view, it is preferable to prepare multiple sets of perforated paper.

As described above, according to the present invention, since the tensile strengths of the perforation lines applied to the paper are made different, anyone can reliably cut the paper.

In the embodiment, the tensile strength of each perforation line is all different, but it goes without saying that only some of the tensile strengths can be made different, and the order of separation based on an index can be set only for these parts.
