本考案は、例えば製図などの際の修正用器具で
ある電動消しゴム装置の改良に関するものであ
る。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of an electric eraser device which is a correction tool for drawing, for example.
従来、電動消しゴム装置の一種として、第２図
に例示した構造のもの（実開昭48−66645号公報
参照）が公知である。
Conventionally, as a type of electric eraser device, one having a structure illustrated in FIG. 2 (see Japanese Utility Model Application Publication No. 48-66645) is known.
すなわち、この電動消しゴム装置は、円盤状消
しゴムａを回転させるモータｂのシヤフトｃにフ
アンｄを設け、消しゴムａを回転させた時に一体
に回転するフアンｄによつて生じる風を利用し
て、消しカスを除去可能としたものである。 That is, in this electric eraser device, a fan d is provided on the shaft c of a motor b that rotates a disc-shaped eraser a, and the eraser is erased by using the wind generated by the fan d that rotates when the eraser a is rotated. This makes it possible to remove debris.
しかし、上記従来公知の電動消しゴム装置によ
ると、以下に列挙するような問題がある。
However, the conventional electric eraser device described above has the following problems.
フアンｄが円盤状消しゴムａの側面に隣接対
向しているので、フアンｄによる送風力が小さ
い。 Since the fan d is adjacent to and opposite to the side surface of the disc-shaped eraser a, the force blown by the fan d is small.
フアンｄによつて生じた風は、円盤状消しゴ
ムａを包囲したキヤツプｅの外周の一部を切欠
いた吹き出し口ｆから吹き出すようになつてお
り、吹き出し口ｆが周方向に長くならざるを得
ないため、消しカスの除去力が乏しい。 The wind generated by the fan d is blown out from an outlet f which is a part of the outer periphery of the cap e surrounding the disc-shaped eraser a, and the outlet f has to be elongated in the circumferential direction. Because of this, the ability to remove eraser particles is poor.
フアンｄによつて生じた風は、円盤状消しゴ
ムａの片側（図中左側）の面に案内されて吹き
出すため、反対側の消しカスが除去されにく
い。 The wind generated by the fan d is guided by the surface of one side (the left side in the figure) of the disc-shaped eraser a and is blown out, making it difficult to remove the eraser residue on the opposite side.
本考案は、このような点に鑑みてなされたもの
で、その目的とするところは、確実な消しカス除
去機能を備えた電動消しゴム装置を提供すること
にある。 The present invention has been devised in view of these points, and its purpose is to provide an electric eraser device having a reliable eraser residue removal function.

In order to solve the above problems, the electric eraser device according to the present invention includes a gripping case, a motor housed in the gripping case, and a rotating shaft driven by the motor that is held via a holder and gripped. Equipped with a rod-shaped eraser that protrudes from the tip of the case to the outside,
A rotating blade is installed inside the gripping case to blow air toward the tip of the gripping case, and the diameter of the rotating blade is a blowout formed between the inner periphery of the tip of the gripping case and the outer periphery of the rotating shaft. The gripping case is larger than the radial width of the opening, and has a streamlined shape whose diameter gradually becomes smaller from the outer circumferential side of the rotary blade toward the outlet.

When the eraser is rotated, the wind generated by the rotating blades that rotate together with the eraser is blown out from the outlet at the tip of the grip case, and removes the eraser residue generated from the tip of the eraser. The rotating blade is
Because it is longer than the radial width of the air outlet, the air sent out from this rotating blade is converged by the inner wall surface of the gripping case that forms a streamlined shape toward the air outlet, increasing the flow velocity and generating momentum from the air outlet. It squirts well and blows away the eraser residue.
以下、本考案を、第１図に示す一実施例を参照

が、漸次小径になるような流線形をなしている。 Inside the gripping case 1, an axial-flow type rotary blade 7 is provided which is attached to the rotating shaft 3 and blows air toward the tip 11 of the gripping case 1 during rotation, and the diameter of the rotary blade 7 is as follows. It is made larger than the radial width of the annular air outlet 12 formed between the inner periphery of the tip 11 of the gripping case 1 and the rotating shaft 3 side. In addition, the cross-sectional shape of the grip case 1 is a portion 13 extending from the outer circumferential position of the rotating blade 7 to the outlet 12 side.
However, it has a streamlined shape that gradually becomes smaller in diameter.

カスを吹き飛ばす。 That is, in this configuration, when the eraser 5 is rotated by the motor 2 via the rotating shaft 3 and the holder 4, the rotating blade 7 is also rotated by the rotating shaft 3 at the same time. The cross-sectional shape of the gripping case 1 is a portion 1 extending from the outer circumferential position of the rotating blade 7 to the outlet 12 side.
3 forms a streamlined shape that gradually becomes smaller in diameter, the wind generated by the rotating blade 7 is converged along the inner wall surface of the streamlined portion 13 when heading toward the outlet 12, and the flow velocity increases. It blows out vigorously from the blow-off port 12 and blows off the eraser residue generated from the tip of the eraser 5.
