Abstract

An object of the present invention is to devise office supplies that can easily and evenly fold various sheets of paper such as A4.
A position corresponding to one third of the length of a side of a sheet to be folded in three is marked from an arbitrary reference point of an envelope or a simple three-fold tool. By aligning one side of the paper with the reference point, folding the side facing the paralleled side parallel to this mark and then folding it, aligning the side aligned with the reference point with the side generated by folding, and making the paper simple and even I was able to fold it in three.

Description

Detailed description of the invention

The present invention relates to a technique for easily and evenly folding a sheet of paper by using an envelope with necessary parts marked in advance or a tri-fold dedicated office supplies (hereinafter abbreviated as simple tri-folder). Is.

When folding various types of paper equally in three, usually the length of the corresponding side is measured, and after marking a portion corresponding to one-third of the length, it is folded using this as a guide. However, when folding a large number of papers of a predetermined size or of the same size, it is cumbersome to perform this work one by one, and a simpler method is required.

Problems that the device tries to solve

In the present invention, a part of an envelope or a simple three-folding tool is marked in advance, and the sheet is folded according to the mark so that the sheet can be easily and evenly folded in three.

Means to solve the problem

  In order to achieve the above object, a position corresponding to one-third of the length of one side of the paper to be folded in advance is marked from an arbitrary reference point of the envelope or the simple three-folding tool. After aligning one side with the reference point, fold the side facing this parallel to this mark. After that, one side of the paper previously aligned with the reference point is folded back to match the side generated by bending, so that the paper can be easily and evenly folded in three. In the case of an envelope, it is convenient that the reference point is a longitudinal side. In the case of a simple tri-folder, a plurality of sheets can be easily adjusted to the reference point at a time by using a protrusion provided on a part thereof as a reference point and pressing one side of the sheet against the protrusion. .

In the following, an embodiment of the present invention will be described by taking, as an example, a case where an A4 sheet is folded in a long envelope No. 3 which is a regular envelope. Commercially available A4 paper has a size of 297 mm long and 210 mm wide, and when it is put in a long No. 3 envelope, it is usually folded in the vertical direction. At that time, it may be appropriately folded in three. However, if the size of each fraction section is different, it does not look very good when the paper is opened. Further, when the tri-folded fraction is larger than the envelope width, it does not enter the envelope.

In order to solve these problems, the present invention uses an envelope or a simple tri-folder that is marked in advance at a position 99 mm away from the reference point (corresponding to one third of the length of the long side of A4 paper). Thus, each of the three-folded fraction portions is uniformly 99 mm. With this width, the folded A4 paper can be placed in the long No. 3 envelope with a margin. However, in actual bending work, since the position of the mark is more easily about 100 to 101 mm from the reference point, the length from the reference point to the mark is 100 mm in the following description.

Hereinafter, the present invention will be described in detail with reference to examples. However, the present invention is not limited to the following examples unless it exceeds the gist.

Example 1 An example in which an A4 sheet is folded in three in the longitudinal direction using an envelope printed with a mark at a margin of 100 mm in the vertical direction from one side (reference point) of the long No. 3 envelope is shown in FIG. Shown in ~ 3.

Example 2 An example in which a simple tri-folder marked at a position 100 mm apart in the vertical direction from a protrusion (reference point) provided on the main body is used to fold A4 paper in the longitudinal direction in FIG. Shown in ~ 6.

As shown in Example 1, after aligning one side of the A4 paper with the vertical side of the long No. 3 envelope, folding the side of the paper facing parallel to the mark printed on the margin of the envelope The portion is one third of the length of the A4 paper in the longitudinal direction, that is, a size of 99 mm. After that, if the remaining two-thirds are folded in half, the entire A4 sheet can be folded into three equal parts with a size that fits into the envelope. Since the mark printed on the margin is not visible after sealing, there is no problem in appearance. In addition, the mark of the upper part of the two marks | markers attached to the margin part of FIG. 1 is a side (FIG. 1) which faces in parallel with the edge | side (upper edge | side of the envelope shown in FIG. 1) used as the reference point in Example 1. This is a mark used when the lower edge of the envelope shown in (2) is used as a reference point.

The second embodiment is devised so that efficiency can be improved when a large number of A4 sheets are folded in three. In the first embodiment, it takes some time to align one side of the A4 paper and one side of the envelope as the reference point. On the other hand, in the second embodiment, it is possible to easily match the reference point of the simple tri-folder with the side of the A4 paper by simply pressing one side of the A4 paper against the projection of the simple tri-folder. I can plan. After aligning one side of the A4 paper to the protrusion, the side facing in parallel with this is folded back to match the mark on the simple tri-folder as in the first embodiment, and then the remaining two thirds. Fold the part in half.

Effect of device

As described above in detail, if the present invention is used, A4 paper can be easily and evenly folded in three.

It is a figure which shows the state which set | placed one side of A4 paper on the one side (reference point) of the longitudinal direction of an envelope on the envelope which printed the trifold position. FIG. 6 is a diagram illustrating a state where one side of an A4 sheet is folded according to a mark indicating a tri-fold position. FIG. 3 is a diagram showing a state in which one side of A4 paper aligned with a reference point of an envelope is folded back in accordance with a side generated by folding in FIG. 2 and is folded in three. It is a figure which shows the state which pressed and put one side of A4 paper to the projection part of the simple trifold tool. It is a figure which shows the state bent according to the mark affixed to the simple trifold tool of A4 paper. FIG. 6 is a diagram showing a state in which one side of A4 paper is folded in accordance with a side bent according to FIG. 5 and folded in three. It is a figure which shows the AB sectional drawing of FIG.
