シヤープペンシル。 A core guide pipe built into the base so as to be slidable back and forth in the axial direction, a lead holder built into the core guide pipe and lightly holding the core, and a first spring biasing the core guide pipe forward in the axial direction. Consisting of a chuck that strongly holds the core axially rearward due to a wedge action between a coupling tool connected to the cap and a tapered part of the coupling tool, and a second spring that biases the chuck axially rearward, In an automatic sharpening pencil that automatically feeds out the lead by the amount of wear on the lead, the elastic force of the first spring is configured to be stronger than the elastic force of the second spring, and the elastic force of the first spring is used to extend the lead guide pipe. The core guide pipe is brought into contact with the mouthpiece and the rear part of the core guide pipe is brought into contact with the chuck to bias the chuck forward in the axial direction, thereby expanding the inside of the chuck so that the core can be inserted thereinto. A self-feeding mechanical pencil.
