う問題があった。(Problems to be solved by the invention) With the above-mentioned invention, for example, when this is used for drafting, a line is often drawn using a scale, but if a thin line is drawn, a pencil is drawn. The core diameter also needs to be thinned (the thickness of the line used for drafting is generally 0.1 to 0.8 mm
However, when the core diameter is small, there is a problem that the core is damaged by the edge of the scale at the time of drawing and the core is likely to be broken.

An object of the present invention is to provide a pencil sharpener capable of forming a core into a small-diameter portion contributing to a writing line and a large-diameter portion for preventing breakage of the core as much as possible. A pencil sharpener provided with a first cutting blade for shaft cutting and a second cutting blade for core cutting in front of the first cutting blade, each of which is provided in an inclined state; The first cutting blade and the second
And the cutting edge of the first cutting blade and the cutting edge of the second cutting blade are arranged so as to be on the same plane. The tip is
The pencil sharpener is arranged at a position radially away from the center of the lead.
（実施例） 以下、添付図面に基づき更に詳細に説明する。(Example) Hereinafter, it demonstrates in detail based on an accompanying drawing.
尚、図中、左方を前方、右方を後方とする。 In the drawings, the left side is the front and the right side is the rear.

設ける必要がある。In the above embodiment, the first cutting blade 3 and the second cutting blade 5 are formed separately because the blade (cutting blade 5) for cutting a core harder than the shaft is made of alumina, zirconium oxide or the like. It is made of ceramics and is a consideration to make it easy for the blade to maintain wear resistance. If the cutting blade 5 is particularly subjected to abrasion resistance, or if the abrasion resistance can be neglected, the cutting blade 3 (SK
And the cutting blade 5 may be integrally formed, but in this case also, it is necessary to provide an interval between the blade forming portions.
次に、本例の動作を第２図に基づき説明する。 Next, the operation of this example will be described with reference to FIG.
