Claims

[Scope of utility model registration request]

A lower half-cylinder body having a tip tube at its tip, an upper half-cylinder body in which a lower part is fitted to the outside of the upper end of the lower half-cylinder body so as to be slidable by a predetermined stroke, and an outer periphery of the upper end of the lower half-cylinder body and an upper half cylinder. A shaft cylinder configured with a protruding strip provided on the outer periphery of the lower end of the body so as to be disengaged when the upper half cylinder body is retreated, an inner cylinder fitted between the upper and lower ends of the shaft cylinder, and an axis of the inner cylinder. The shaft material inserted into the core,
A passage for the core to pass provided from the lower end of the shaft member to the middle part of the upper part of the shaft member, an opening for the passage of the core that communicates the passage with the outer circumferential surface of the shaft member between the lower part and the upper end of the passage; Two guide plates that extend from both sides of the opening and face the inner circumferential surface of the inner cylinder, an inclined plate that is located between the lower ends of these guide plates to guide the core into the passage, and A chuck is provided on the outer periphery of the shaft member so that the upper end of the guide plate is open between the chuck, which communicates with the passage and is inserted into the end of the tip tube so that it can be inserted and removed, and which escapes from the tip tube and opens when the button is pressed. Cores of three or more colors are housed by a bottom plate provided and protruding plates arranged in a radial pattern from the inner circumferential surface of the inner cylinder so as to be located between the bottom plate and the upper end of the shaft member and facing the outer periphery of the shaft member. a compartment, a shaft member provided to bush the shaft member at the upper end of the upper half cylinder body, a protrusion provided so as to extend from the inner surface of the upper half cylinder body and engage with the inner cylinder;
a protruding piece provided on the outer periphery of the lower end of the shaft member; a slider positioned above the protruding piece and fitted into a longitudinally elongated hole of the inner cylinder;
A mechanical pencil consisting of an annular protrusion provided on the inner periphery of the lower half-cylindrical body so as to collide with the slider of the upper half-cylindrical body and push down the protruding piece when the upper half-cylindrical body retreats.
