シルの芯繰り出し装置。An engaging protrusion is provided on the outer surface of the chuck case that accommodates the ball chuck or on the inner surface of the chuck case holder that is disposed on the outer periphery of the chuck case and is biased backward by a knock spring. A fitting recess is provided in the outer surface of the chuck case or on the outer surface of the chuck case, in which the engaging protrusion fits and the locking state can be maintained until a certain knocking pressure is reached, and the fitting in the chuck case holder is After the front end of the chuck case hits the inner wall surface of the shaft cylinder due to advancement by knocking, the front end of the chuck case is moved to the required position on the side of the recess or the required position in front of the fitting recess in the chatter case, and then the above-mentioned locked state is achieved by further knocking. The retaining protrusion that was released engages again, and after the knocking force is released, the elastic force of the knock spring is transmitted to the chuck case and the chuck case is moved back, so that the outer stepped portion of the chuck case collides with the stepped portion inside the shaft cylinder. 1. A mechanical pencil lead feeding device using a ball chuck, characterized in that an engagement stepped portion is provided which releases the locked state by the elastic force of a knock spring after the ball chuck is released.
