(57) [Summary] [Problem] When performing a drawing operation using a triangle ruler, powder of a core such as a pencil or a mechanical pencil enters between the triangle ruler body and the sheet and soils the sheet. A triangular ruler is provided with a hemispherical projection on one surface to make a point of contact with a sheet not a surface of the main body but a point.
Description
【０００１】[0001]
この考案は、三角定規に関する。 This invention relates to a triangle ruler.
【０００２】[0002]
作図などの作業で直線や平行線を書く時に三角定規を使用する。 Use a triangle ruler when drawing straight or parallel lines for tasks such as drawing.
【０００３】[0003]
上記作業において、鉛筆やシャープペンシルなどの芯の粉が三角定規と用紙の間 に入り用紙が汚れてしまう。 In the above operation, the powder of the core such as pencil or mechanical pencil gets between the triangle ruler and the paper, and the paper becomes dirty.
【０００４】 そこで、この考案の課題は作図などの作業中に用紙を汚さない三角定規を提供す る事である。Accordingly, an object of the present invention is to provide a triangular ruler which does not stain a sheet during work such as drawing.
【０００５】[0005]
上記課題を解決するために三角定規本体片面に半球状の突起物をつけることで用 紙との接点を本体の面ではなく点にする。 In order to solve the above problem, a hemispherical projection is provided on one side of the triangular ruler body so that the point of contact with the paper is not a surface of the main body but a point.
【０００６】[0006]
従来の三角定規本体の片面に0.5〜0.6ｍｍ程度の半球状の突起物を規則的に配列 する。 Hemispherical protrusions of about 0.5 to 0.6 mm are regularly arranged on one side of the conventional triangular ruler body.
【０００７】[0007]
三角定規本体片面に半球状の突起物をつける事で、用紙と三角定規本体に隙間が でき、接点が点になり面での摩擦により用紙が汚れていたのに比べて点での摩擦 なので用紙が汚れにくい。 By attaching a hemispherical protrusion on one side of the triangle ruler body, a gap is created between the paper and the triangle ruler body, the point of contact becomes a point, and the friction at the point is compared to the fact that the paper is dirty due to friction on the surface. Is hard to get dirty.
【０００８】 又、フィルム用紙などにインク等を使って作図する時に三角定規本体と用紙との 間にインクが入りにじむという事もなくなった。In addition, when drawing with ink or the like on a film paper or the like, ink does not flow between the triangle ruler body and the paper.
