歇移動装置。[Claims for Utility Model Registration] A core guide pipe that is built into a shaft cylinder so as to be able to slide freely in the axial direction and is biased forward in the axial direction, and a core guide pipe that moves the core forward in the axial direction with a slight force, but the shaft At the rear in the direction, there is a lead holding device that holds the lead with strong force, and as the lead wears out, the lead guide pipe retreats to allow writing, and when the lead guide pipe moves forward in the axial direction, it follows the lead guide pipe. A self-feeding sharp pencil in which a lead is fed out includes a fastening member having a tapered surface inclined in the axial direction, and a flat member having a flat surface extending flat in the axial direction between the abutting stage and the receiving stage. The retainer is configured such that the tapered surface and the flat surface face each other, and is loosely fitted between the abutting stage and the receiving stage of the flat member, and is frictionally connected to the fastener member via the elastic body,
A rotatably provided ball on the retainer is positioned so as to be able to abut between the tapered surface of the fastener member and the flat surface of the flat member, and either the fastener member or the flat member is fixed to the core guide pipe. A device for intermittent movement of a lead guide pipe of an automatic sharpening pencil, characterized in that the other is provided on the barrel.

し式シヤープペンシルの芯ガイドパイプ間歇移動
装置。 A core guide pipe is built into the shaft cylinder so that it can slide freely in the axial direction and is biased forward in the axial direction.The core is moved forward in the axial direction with a small force, but is held in the rear direction with a strong force. When the lead wears out, the lead guide pipe retreats to allow writing, and when the lead guide pipe moves forward in the axial direction, the lead is automatically fed out according to the lead guide pipe. In a pencil, a fastener member has a tapered surface inclined in the axial direction, and a flat member has a flat surface extending flat in the axial direction between the abutting stage and the receiving stage, and the tapered surface and the flat surface are mutually connected. A retainer configured to face each other and loosely fitted between the abutting stage and the receiving stage of the flat member is frictionally connected to the fastener member via the elastic body, and
A ball rotatably provided on the retainer is positioned so as to be able to abut between the tapered surface of the fastener member and the flat surface of the flat member, and either the fastener member or the flat member is fixed to the core tank. An intermittent moving device for a lead guide pipe of an automatically feeding type sharp pencil, characterized in that the other is provided in the barrel.
