1 is an exploded perspective view showing an example of a conventional mechanical pencil.

As shown in FIG. 1, there is a sharp shim fixing part 10 for fixing a shim used in the mechanical pencil, and a sharp shim supplying chamber connected to the sharp shim fixing part 10 to supply the sharp shim to the sharp shim fixing part 10. 20) There is.

The sharp shim supply chamber 20 is configured to store the sharp shims therein. The sharp shims in the sharp shim supply chamber 20 are loaded into the sharp shim fixing part 10 one by one by gravity and a user's pressing or rotating operation.

The sharp shim fixing part 10 pushes the loaded sharp shim little by little by the user's pressing or rotation operation, and newly fixes the position of the sharp shim with respect to the sharp pencil.

The sharp pencil body 30 is coupled to the circumference of the sharp shim supply chamber 20 so that the user can comfortably hold the mechanical pencil, and the upper end of the sharp shim supply chamber 20 prevents the sharp shim stored in the sharp shim supply chamber 20 from escaping. Faucet 50 is coupled to facilitate the user's pressing operation.

Such a conventional mechanical pencil has the following problems.

In order to eliminate the inconvenience of carrying the sharp shim container separately or the discomfort of frequently changing the sharp shim in the sharp shim supply chamber 20, if too many sharp shims are put in the sharp shim supply chamber 20, the sharp shim fixing part must be loaded only one by one. Sharpness often occurs at (10).

Since the sharp shim fixing part 10 is designed to be loaded with only one sharp shim, when two or more sharp shims enter the driveway of the sharp shim fixing part 10, the operation of the mechanical pencil stops.

It is very cumbersome and cumbersome for the user to disassemble the sharp shim fixing part 10 to pierce the access road of the blocked sharp shim fixing part 10 to solve such a failure. In addition, frequent failures take valuable time and effort from the user.

Even if such a repair is impossible, the mechanical pencil cannot be dismantled by the user's manipulation, or if a mechanical pencil that cannot penetrate the access path of the blocked sharp core fixing part 10 is used, the mechanical pencil will be discarded. There is no choice but to.

In order to prevent the failure caused by the sharp core densities in the sharp shim fixing part 10, it is common to fill an appropriate amount of the sharp shim in the sharp shim supply chamber 20, which is inconvenient to carry the sharp shim reservoir or the sharp shim supply chamber 20 ), Causing sharp discomfort often.
