The case 2 is composed of two members detachably coupled to each other so that the cartridge 6 can be replaced, and the through-holes of the case 2 can be protruded to the outside of the case 2. 12) is formed.

Therefore, after all the ink contained in the cartridge 6 is used, the case 2 may be separated from each other, and a new cartridge may be replaced and reassembled.

Ink is injected into the cartridge 6, and the cartridge 6 may use what is provided in a conventional sign pen, and thus detailed description thereof will be omitted.

The rear end of the case 2 is spaced apart from each other so that the operating unit 8 is assembled and supported to fix the operating state of the operating unit, and a plurality of first and second fixing grooves 14a and 14b are formed. .

The operating unit 8 is an operating shaft 16 for advancing the cartridge 6, and the operating shaft 16 extends from the operating shaft 16 and moves together while being elastically deformed when the operating shaft is operated. It comprises a holding unit 18 for holding.

The working shaft 16 is positioned in a state where the front end is in surface contact with the end of the cartridge 6, and the other end protrudes out of the rear end of the case 2.

The holding unit 18 is formed with a stopper 20 for fixing the state in which the operating shaft 16 is moved, and a return button 22 to return the moved operating shaft 16 to its original position.

The operation shaft 16 and the cartridge 6 are moved while receiving the outward elastic force of the elastic member 10 made of the coil spring when the operation part 8 is operated, and the elastic member 10 has both ends of the case 2. And supports 24 and 26 formed in the cartridge 6, respectively, to provide elastic force.

When the sign pen according to the present invention is not in use, the nib 4 is positioned inside the case 2 by the outward elasticity of the elastic member 10 as shown in FIG. 1, and the stopper 20 and the return button ( 22 are held by the fixing grooves 14a and 14, respectively.

The tip tip of the case 2 is provided with a nib dry prevention means to prevent the nib 4 from drying out when the sign pen is not used.

As shown in FIG. 2, the nib dry prevention means includes a blocking film 28 fixed to the front end of the case 2 by adhesion or the like.
