穴が矩形字消し板１の隅にある場合には、保持し
ずらいなどの欠点があつた。 Conventionally, when making corrections during drafting work, holes 10 of various shapes are drilled into a rectangular thin plate as shown in FIG.
A rectangular character eraser board 1 having numbers 1 and 102 was held with appropriate holes aligned with the figures and characters to be erased, and the figures and characters in the holes were erased from the top with an eraser. However, with the rectangular eraser board 1 having such a structure, as shown in FIG. When the rectangular eraser board 1 is located at a corner, there are drawbacks such as difficulty in holding it.
本考案の目的は、このような従来の欠点を除去
し保持時に穴よりはみ出た指先で図面上の図形や
文字を汚すことなく、しかも有する種々の穴すべ

し板を提供するものである。 The purpose of this invention is to eliminate such drawbacks of the conventional technology, and to develop a new method that prevents the fingertips protruding from the holes from smearing figures and characters on the drawing when holding the hole, and also allows holding all of the various holes in a uniform manner. The present invention provides a circular character eraser board.
以下本考案の実施例について図面により詳細に
説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

を備えていてもよい。 In Figures 3 and 4, 2 is an arcuate hole 2.
This is a circular eraser board having numbers 01, 202, 203, and 204, and is provided with a circular press plate 3 rotatably supported by a support shaft 4 and provided with a window part 301 cut out in a fan shape. The shape of the hole provided in the circular eraser board 2 may be any shape such as a circle 205, an oval 206, a rectangle 207, or a triangle 208. Furthermore, the material constituting the circular push plate 3 is transparent, and as shown in FIG.
may be provided.
次に前記実施例の動作について述べる。製図作

ができるのは明らかである。 Next, the operation of the above embodiment will be described. When correcting drawings, characters, etc. in drafting work, rotate the circular eraser board 2 so that the hole 201 of the shape suitable for the correction area is located inside the push plate window 301 or 302, and apply it to the correction area. By holding the circular push plate 3 with your fingertips and erasing the inside of the hole 201 with an eraser, you can easily erase without staining areas other than the areas to be corrected. It is obvious that if the shape of the area to be corrected is different, the correction can be easily made by rotating the hole so that a hole suitable for the shape is located in the window portion 301 or 302.
