ープペンシル。 A chuck body 9 that clamps the core and prevents the core from retreating.
A chuck mechanism has a chuck actuating body 6, and a first slider 16 that moves backward according to writing pressure and a lead-carrying member 22 are installed in front of the chuck mechanism, and the lead-carrying member 22 increases each time writing pressure is applied. A sharpening pencil capable of automatically feeding out a lead to a fixed length and having a wedge means for locking the retracting second sliders 20 at the retracted position, has a lead guide tube 24 in front of the second slider. A third slider 26 is provided which is elastically biased rearward so as to come into contact with the front end of the second slider, and when writing in a state where the lead does not protrude from the lead guide tube, the third slider 26 is retracted due to the pressure of the pen. The second slider is moved back to bring the lead into contact with the paper surface, and the chuck body that clamps the lead is moved back together, and when the writing pressure is released, the second slider is locked at the retreated position by the wedge means, A sharp pencil in which a chuck body that holds the lead moves forward to cause the lead to protrude.
