欠点を有していた。 Conventional sharp pencils, which rotate to make the cap appear and disappear or to feed out the lead, have a knob that does not protrude beyond the rear end of the sheath, giving it a very nice appearance.In particular, it is known that it is effective in making it possible to develop set products that have the same appearance as fountain pens. It was getting worse. Therefore, the applicant of this application had already devised and applied for a sharpening pencil that rotates to make the mouthpiece appear and disappear and the lead to come out (Utility Application No. 87317-1983).
Jitsugan No. 54-100148). However, Utility Model Application No. 54-87317 required a cam mechanism to move the cap in and out, and a cam mechanism to feed out the core, making the structure extremely complicated and unsuitable for production. On the other hand, Utility Model Application No. 54-100148 had the disadvantage that the cap had to be moved in and out each time to feed out the lead, making the operation of drawing out the lead cumbersome.

転が止められ、第１図の筆記状態に復帰する。 In the sharp pencil configured in this manner, when the sheath 5 is rotated to the left, the inner pipe 4 and the cam 6 are also rotated to the left. However, the core tank 7 cannot rotate because the protrusion 7A is inserted into the cut groove 2D of the inner body 2, so the protrusion 7A of the core tank 7 cannot rotate.
rides on the locking part 6C provided at the front end of the cam 6 and releases the return spring 8 along the protruding and retracting inclined part 6A.
He retreats while being shot at. In conjunction with the retreat of the core tank 7, the chuck 10, tightening ring receiver 13, and cap 1
2 are both retracted, and as shown in FIG. 2, the cap 2 is recessed from the tip of the tip 3 to be in a portable state.
When attempting to write from the portable state shown in FIG.
The pen moves forward along the protruding and retracting inclined portion 6A, rides on the protrusion of the cam 6, and returns to the writing state shown in FIG. To feed out the lead 15 from this state, by further rotating the sheath 5 to the right, the protrusion 7A of the lead tank 7 advances along the feeding slope 6B of the cam 6, and advances together with the base 12. Then, the outer stage 12A of the cap 12 comes into contact with the inner stage 3A of the tip 3. When the sheath 5 is further rotated to the right, the chuck spring 14 is compressed because the base 12 and the tightening ring receiver 13 cannot move forward, and the chuck 10 holding the core 15 and the core tank 7 are moved forward, causing the tightening ring to move forward. 11 is brought into contact with the locking stage 12B of the base 12. Therefore, the core 15 is drawn out by the moving distance of the tightening ring 11,
The chuck 10 is released from the tightening ring 11 and expanded. When the sheath 5 is further rotated to the right, the front end of the chuck 10 comes into contact with the inner stage 12C of the base 12, resulting in the state shown in FIG. 3, and the clockwise rotation of the sheath 5 is stopped.
Next, when the force for rotating the sheath 5 to the right is released, the elastic force of the chuck spring 14 causes the chuck 1 to rotate.
0 and the core tank 7 are ejected rearward, the sheath 5 is rotated to the left, and the protrusion 7A of the core tank 7 is retreated along the protruding and retracting inclined portion 6B of the cam 6. Then, first, the head 10A of the chuck 10 is attached to the tightening ring 11.
The core 15 is tightly held by being brought into contact with the core 15 and closed. Furthermore, the sheath 5 is rotated to the left by the elastic force of the return spring 8, and the lead tank 7 is moved backward, creating a slight gap between the inner stage 3A of the tip 3 and the outer stage 12A of the cap 12. And the protrusion 7A of the core tank 7
When it is locked by the locking portion 6C of the cam 6, the left rotation of the sheath 5 is stopped and the writing state shown in FIG. 1 is restored.

By simply rotating the sheath left and right, the tip of the cap can be made to protrude or retract from the body, and the core can also be extended, eliminating the risk of tearing clothes or causing injury due to the tip of the cap. This eliminates the need for products with a variety of external appearances. Furthermore, this invention has the effect of causing the cap to protrude from the tip by simply moving the lead tank forward by rotating the sheath, and the action of moving the chuck forward inside the cap that is in contact with the tip to feed out the core. As a result, the structure can be expected to be simpler than the conventional structure in which the structure for protruding the cap and the structure for feeding out the core are separate.
