る自動繰り出し式シヤープペンシル。 A cap, a slider built into the cap so that it can slide in the axial direction, a lead holder that is integrated with or separate from the slider and holds the lead with an appropriate force, and a spring that urges the slider forward in the axial direction. Then, the core holder, which is urged backward in the axial direction with a weak force, comes into contact with the fastener, and due to the wedge effect caused by the contact between the lead holder and the fastener, a slight force is applied to the core forward in the axial direction. A self-feeding sharp pencil consists of a lead holder that is moved at the axial direction but is held in the axial rear direction with a strong force. 1. A self-feeding sharpening pencil characterized in that a tapered surface is formed on either one of the fasteners housed therein, and a raised curved portion that comes into contact with the tapered surface is formed on the other side.
