In the sharp pencil which feeds out the lead S by operating the lead feeding mechanism 7, the lead chuck 9 of the lead feeding mechanism 7 is integrally connected to the rear end of the lead chuck 9, and together with the lead feeding mechanism 7, the lead chuck 9 is connected to the rear end of the lead chuck 9. a cam engaging means 64 that is movably inserted in the axial direction and engaged in the axial direction;
connected to the rear outer cylinder 17 and rotatably and removably inserted into the rear side of the front outer cylinder 1;
It is characterized in that it is equipped with a cam cylinder 14 to which the cam engaging means 64 is press-fitted at its front end, and the cam cylinder 14 is rotated together with the rear outer cylinder 17 to send out the core S. Sharpening pencil. (2) The cam cylinder 14 causes the lead guide 4a to protrude from the tip tool 3 by a large rotation in one direction, and by a small rotation after the protrusion, the cam cylinder 14 moves the cam in a direction to sequentially send out the leads S from the lead guide 4a. A large cam surface 141 that slides the engagement means 64, a small cam surface 144 that slides the cam engagement means 64 in the direction of releasing the chuck of the lead delivery mechanism 7 by rotation in the other direction, and the lead delivery mechanism 7. a locking portion 145 that locks the cam engaging means 64 at the chuck open position of No. 7;
The sharp pencil according to claim 1, wherein the lead guide 4a can be retracted and stored in the chuck open position when the lead is stored.
