First, the main body case 100 may be formed by injection molding using a synthetic resin material or a metal material, or may be formed by a molding method, and may have a hollow pipe or tube shape.

The main body case 100 may be formed of one or two cases. In the illustrated example, the two cases are screwed or interference fit, and the nip hole 102 can be formed at one end of one case of the cone type. have.

On the circumferential surface of the main body case 100 on the opposite side to the nip hole 102 side, a clip portion 110 can be installed which is capable of internally organizing the clip portion and releasing the clip portion.

The knocking portion 120 that protrudes and immerses the nip 160 through the nip hole 102 in the main body case 100 by the pressing operation can be installed close to the clip portion 110. [

The knocking unit 120 can be installed to transmit a force to the cartridge 130 by the user's pressing operation. The knocking unit 120 has a tubular shape having a small diameter circumferential surface and a large diameter circumferential surface, And the other end of the large diameter side is sealed.

Meanwhile, the cartridge 130 inserted into the main body case 100 together with the spring 140 may have an internal volume of a predetermined capacity corresponding to the ink storage region.

This cartridge 130 has a tank portion 132 having the largest diameter, a connecting portion 133 having a relatively smaller diameter than the tank portion 132, a connecting portion 133 having a relatively smaller diameter than the connecting portion 133, And a nip extension shaft portion 134 formed integrally therewith.

An end side surface of the nip extension shaft portion 134 is provided with any contents (for example, paper) stored in the tank portion 132 from the tank portion 132 by a normal ink supply system (e.g., capillary phenomenon, pressure difference, : Ink, etc.) according to a normal supply method corresponding to the type of the writing instrument.

A step portion 136 having a predetermined length may be formed on the inside of the end portion of the cartridge 130 coupled with the nip fixing means 150.
