A pencil insertion hole 1 is formed at an end of one side surface of a case body 2 made of plastic, and a shaving blade 4 made of stainless steel is attached to an inner surface portion thereof. Case body 2
In, a cylindrical dial 3 is arranged on the side surface opposite to the side surface on which the pencil insertion hole 1 is provided. The dial 3 integrally has a rotary mount 9 having a screw hole 8 therein, and is rotatable with respect to the case body 2 by the rotary mount 9.
In addition, the case main body 2 is mounted so as to be capable of moving forward by a required amount. A return spring 10 is interposed between the dial 3 and the case body 2 to push the dial 3 outward and retract it. A core contact piece 7 is arranged behind the pencil insertion hole 1 inside the case body 2 and in front of the rotary mount 9 of the dial 3. This core contact piece 7
Has a narrow groove 11 on its side surface and a screw shaft 12 projecting from the rear part thereof. The sharpening blade 4 is movably fitted in the narrow groove 11, and the screw shaft 12 is attached to the rotary mount 9 of the dial 3. It is screwed into the screw hole 8. Incidentally, reference numeral 13 in the drawing
Is a detachable lid for discharging the shavings accumulated inside the case body 2.

利である。As described above, the dial 3 can be moved forward by a required amount toward the inside of the case body 2. Therefore,
As shown in FIG. 1, when the dial 3 is pushed inward against the return spring 10, the core contact piece 7 is instantly moved integrally with the dial 3, and the pencil insertion hole 1
It is possible to extrude and remove the core 14 that is jammed in the back of the core. As shown in FIG. 2, by rotating the dial 3, the thickness and length of the lead 6 of the pencil 5 can be adjusted. That is, when the dial 3 is rotated, the core contact piece 7 is linearly moved by the screw feed of the rotary mount 9, so that the core contact piece 7 is displaced with respect to the dial 3 and also with respect to the scraping blade 4. The tip of the lead 6 of the pencil 5 inserted into the pencil insertion hole 1 comes into contact with the front surface of the lead contact piece 7, so if the position is changed, the scraped length of the lead 6 of the pencil 5 also changes. Can be made. Therefore, the turning thickness and length of the lead 6 of the pencil 5 can be adjusted by rotating the dial 3. In addition, dial 3
It is convenient to engrave a scale that is a standard for the cut thickness and length.

る。Next, FIGS. 4 to 6 show a second embodiment. A pencil insertion hole 1 is formed at an end of one side surface of a case body 2 made of plastic, and a shaving blade 4 made of stainless steel is attached to an inner surface portion thereof. A dial 3 is rotatably attached to the case body 2 on a side surface of the case body 2 opposite to the side surface provided with the pencil insertion hole 1. The dial 3 has an axial groove 15 on its inner surface. The dial 3 has a center hole 16, and a push button 17 is arranged in the center hole 16. The push button 17 has a protrusion 18 on its outer surface.
8 is fitted in a groove 15 provided on the inner surface of the dial 3. Therefore, the dial 3 and the push button 17 rotate integrally, but the push button 17 is slidable in the axial direction with respect to the dial 3 and can independently move forward. A rib 19 is provided on the inner surface of the push button 17.
A core contact piece 7 is arranged at the back of the push button 17 in the back of the pencil insertion hole 1 inside the case body 2. The core contact piece 7 is prevented from rotating by the case body 2. The core contact piece 7 has a narrow groove 11 on its side surface, and the shaving blade 4 is movably fitted in the narrow groove 11. The core contact piece 7 is integrally provided with a slide cam 21 at the rear via a shaft portion 20. As shown in FIG. 6, the slide cam 21 is provided with a cam portion 22 that is displaced in the axial direction on the peripheral side surface. The slide cam 21 is pushed rearward by the return spring 10, and the tip of a rib 19 provided on the inner surface of the push button 17 is brought into contact with the cam portion 22.

ある。As shown in FIG. 4, the push button 17
When is pushed inward against the return spring 10, the core contact piece 7 is instantly moved integrally with the push button 17, and the broken core 14 stuck in the back of the pencil insertion hole 1 is inserted into the pencil insertion hole 1. It can be eliminated by pushing it toward the opening. As shown in FIG. 5, by turning the dial 3, the thickness and length of the lead 6 of the pencil 5 can be adjusted. That is, when the dial 3 is rotated, the push button 17 also rotates integrally. On the other hand, since the slide cam 21 cannot rotate together with the core contact piece 7,
The tip of the rib 19 slides on the cam portion 22 of the slide cam 21 by the rotation of the push button 17. This allows
Since the slide cam 21 is displaced in the axial direction, the core contact piece 7
Also moves linearly in the front-back direction and is displaced with respect to the shaving blade 4. Since the tip of the lead 6 of the pencil 5 inserted into the pencil insertion hole 1 comes into contact with the front surface of the lead contact piece 7, if the position of the lead 5 is changed, The length can be changed. Therefore,
By turning the dial 3, the scraped thickness and length of the lead 6 of the pencil 5 can be adjusted. It should be noted that it is convenient to engrave a scale on the dial 3 which serves as a guide for the cut thickness and length.
