Description

本発明は用紙等を裁断する際に用いる裁断機に関し、特に折り紙など正方形の方形状に用紙を裁断したい場合に用いる裁断機に関する。   The present invention relates to a cutting machine used when cutting paper or the like, and more particularly to a cutting machine used when cutting paper into a square shape such as origami.

従来、用紙裁断機としては平板に刃物の端の部分を固定し、刃物を上下動させて用紙を裁断するものが知られている。しかし、刃物を有することから安全性に難があり、特に子供向けの裁断機としては適していない。
また、定規などを用いて用紙を手で裁断する方法が従来より用いられている。しかし、この方法では用紙を２分割することはできるが、折り紙に適した正方形の用紙を得ることはできない。 2. Description of the Related Art Conventionally, as a paper cutting machine, there is known a machine that cuts a paper sheet by fixing the edge portion of the blade to a flat plate and moving the blade up and down. However, since it has a blade, safety is difficult, and it is not suitable as a cutting machine especially for children.
In addition, a method of manually cutting paper using a ruler or the like has been conventionally used. However, with this method, the paper can be divided into two, but a square paper suitable for origami cannot be obtained.

実開昭６２−７９８３号公報Japanese Utility Model Publication No. 62-7983

本発明は上記事情に鑑みてなされたもので、煩雑でなく一度の操作で正方形の用紙を得ることができ、刃物を使用しないため安全性が高い子供向けの裁断機を提供する。   The present invention has been made in view of the above circumstances, and provides a cutting machine for children that can obtain a square sheet with a single operation and is highly safe because it does not use a blade.

方形板状の上板と下板との間に用紙を挿入して裁断する用紙裁断機であって、前記上板の隣り合う１組の辺と相対する前記下板の隣り合う１組の辺を用紙の厚み分だけ上下動可能に嵌合する遊嵌部とし、前記上板の他の隣り合う１組の辺と相対する前記下板の他の隣り合う１組の辺を開放し間隙を形成して間隙部とした用紙裁断機。
前記上板の一部に貫通孔を設けて、裁断後の用紙を排出可能とした用紙裁断機。 A sheet cutting machine for inserting and cutting a sheet between an upper plate and a lower plate of a rectangular plate shape, wherein the adjacent pair of sides of the lower plate is opposed to the adjacent set of sides of the upper plate Is a loosely fitting portion that fits up and down by the thickness of the sheet, and the other adjacent pair of sides of the lower plate facing the other adjacent set of sides of the upper plate is opened to form a gap. A paper cutter that forms gaps.
A paper cutting machine in which a through hole is provided in a part of the upper plate so that paper after cutting can be discharged.

本発明は、一度の操作で正方形の用紙を得ることができ、刃物を使用しないため安全性が高い子供向けの裁断機である。
また、上板の一部に貫通孔を設けた場合は、貫通孔に直接指を差し入れ、或いは貫通孔にスライド可能なゴムなどを装着して用紙を排出することが可能である。 The present invention is a cutting machine for children that can obtain a square sheet by a single operation and has high safety because it does not use a blade.
Further, when a through hole is provided in a part of the upper plate, it is possible to insert a finger directly into the through hole or attach a slidable rubber or the like to the through hole to discharge the paper.

以下に、実施例を挙げて本発明をより詳細に説明するが、本発明は、これら実施例により何ら制限されるものではない。   Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited to these examples.

図１は本実施例の全体斜視図である。
図面において、１は方形状に形成した上板で、隣り合う１組の辺に上板遊嵌部をそれぞれ設けてある。また、上板の中央部分には貫通孔２が２箇所設けてあり、上板表面の角には窪み３を設け、上板裏面には複数個の突起４が設けてある。
６は方形状に形成した上板で、前記上板１と相対する隣り合う１組の辺に下板遊嵌部をそれぞれ対応する箇所に設けてある。
本実施例では、上板１の上板遊嵌部と下板２の下板遊嵌部を上下動可能となるように遊びを設けて嵌合し遊嵌部９としてある。当該遊嵌部９は遊びを設けることが好ましく、当該遊びが間隙部７となって用紙が挿入できる。 FIG. 1 is an overall perspective view of the present embodiment.
In the drawings, reference numeral 1 denotes an upper plate formed in a square shape, and an upper plate loose fitting portion is provided on each pair of adjacent sides. Further, two through holes 2 are provided in the central portion of the upper plate, a recess 3 is provided at a corner of the upper plate surface, and a plurality of protrusions 4 are provided on the rear surface of the upper plate.
Reference numeral 6 denotes an upper plate formed in a square shape, and lower plate loose fitting portions are provided at positions corresponding to a pair of adjacent sides opposed to the upper plate 1, respectively.
In this embodiment, play is provided so that the upper plate loosely fitting portion of the upper plate 1 and the lower plate loosely fitting portion of the lower plate 2 can be moved up and down to form the loosely fitted portion 9. The loose fitting portion 9 is preferably provided with play, and the play becomes the gap portion 7 so that a sheet can be inserted.

次に、紙を裁断する工程について説明する。
窪み３を下方に押すとテコの原理で突起４側の間隙部７がやや大きめに広がる。下板６で沿って停止するまで紙をその間隙部７に挿入し、図２の状態とする。
次に、突起４部分を下方に押すと突起４が紙を押圧し、紙全体が固定される。その状態で紙の一部を掴み、窪み３方向へやや上方へ持ち上げながら引く。そうすると、紙は上板１の形状を残して図３のように裁断される。 Next, the process of cutting paper will be described.
When the depression 3 is pushed downward, the gap 7 on the projection 4 side is slightly enlarged on the principle of leverage. The paper is inserted into the gap 7 until it stops along the lower plate 6, and the state shown in FIG.
Next, when the protrusion 4 is pushed downward, the protrusion 4 presses the paper, and the entire paper is fixed. In that state, grab a part of the paper and pull it while lifting it slightly upward in the direction of the recess 3. Then, the paper is cut as shown in FIG. 3 while leaving the shape of the upper plate 1.

次に、窪み３を下方に押すとテコの原理で突起４側の間隙部７が広がり、貫通孔２に指を入れて突起４側へ残紙を送り出すと、正方形の用紙が得られる。
このように本実施例は、刃物を使用せず、かつ、何度も紙を裁断することなく、一度の操作で正方形の用紙を得ることができる。 Next, when the depression 3 is pushed downward, the gap 7 on the projection 4 side is widened by the principle of leverage, and when a finger is put into the through hole 2 and the remaining paper is fed out to the projection 4 side, a square paper is obtained.
As described above, the present embodiment can obtain a square sheet by a single operation without using a blade and without cutting the paper many times.
