The stamp unit 43 can move up and down in a vertical direction by a cylinder device 431 connected thereto, and the cylinder device 431 can slide in a horizontal direction by a sliding member 432 .

More specifically, the stamp unit 43 descends by the cylinder device 431 and contacts the printing original plate 433, as shown in FIG. 9(a), before the writing instrument P reaches the printing position. can do. For example, since the printing original plate 433 is filled with ink and a pattern or phrase to be printed on the writing instrument P is embossed or engraved on the lower surface of the stamp unit 43, the stamp unit 43 is printed. When contacting the original plate 433, ink may be smeared on the lower surface engraved with patterns or phrases. However, it is not limited to that the printing original plate 433 is filled with ink and a pattern or phrase is engraved on the lower surface of the stamp unit 43 in an embossed or intaglio form, and can be variously modified into a printable structure. For example, when ink is filled in a state in which patterns or phrases are engraved on the printing original plate 433 in an embossed or intaglio form and the stamp unit 43 contacts the printing original plate 433, the lower surface of the stamp unit 43 is printed. Patterns or phrases engraved on the original plate 433 may be buried. The stamp unit 43 is raised by the cylinder device 431 in a state in which ink is applied, and simultaneously or sequentially, as shown in FIG. 9(b), the sliding member 432 moves the seating frame 42 You can slide forward towards the . When the stamp unit 43 slides and overlaps the writing instrument P to be printed, as shown in FIG. ) Can be printed by applying ink to at least one of the body portion P2 and the clip portion P3. When the stamp unit 43 stamps and prints the writing instrument P, the elastic pressing unit 45 may apply an elastic force to the writing instrument P to fix the writing instrument P. At the moment when the stamp unit 43 takes the writing instrument P or returns to its original position after taking the writing instrument P, the writing instrument P may move or be suddenly separated from the indented groove 42a. If the writing instrument P moves or is suddenly separated from the indented groove 42a, printing may not be performed properly or printed ink may be smeared, resulting in defects. The elastic pressing unit 45 is to prevent this problem, and is coupled to one side of the rotating plate 41 so as to be able to move up and down to intermittently apply elastic force to the writing instrument P.

Although not shown in the drawings, when printing is completed, the stamp unit 43 is raised again by the cylinder device 431 and slides backward by the sliding member 432, and the above-described series of processes can be repeated. there is.

Referring back to FIGS. 1 and 8 , the writing instrument P that has been printed in the printing unit 40 may be discharged by the discharging unit 50 . The discharge unit 50 may include a second transfer unit 51 and a separator 52 .

The second transfer unit 51 is formed in a conveyor structure to transfer the printed writing instrument P in the horizontal direction, and includes a pair of belt pulleys 511 spaced apart from each other and arranged side by side, and a pair of belt pulleys. It may include a conveyor belt 512 connected to 511 and circulating while forming a closed loop, and a motor (not shown) for rotationally driving at least one of the pair of belt pulleys 511. there is. If necessary, a separate shield (not shown) may be installed on at least one side of the conveyor belt 512 to prevent the writing instrument P from leaving, and a drying device (not shown) for drying ink is provided It could be. Since the second transfer unit 51 is a normal conveyor, a detailed description of its structure and operation will be omitted.

The separation unit 52 separates the writing instrument P inserted into the indentation groove 42a from the seating frame 42 and places it on the second transfer unit 51, which can move up and down in the vertical direction and slide in the horizontal direction at the same time. It can be formed as a movable structure. That is, the separation unit 52 descends toward the seating frame 42 to hold the pair of printed writing instruments P at the same time, rises again, and slides in a horizontal direction toward the second transfer unit 51, When reaching the transfer unit 51, it descends again, and the writing instrument P can be put down on the conveyor belt 512 of the second transfer unit 51. The separation unit 52 slides along the rail 53 coupled to the main body 60 and can be gripped by pressing both sides of the writing instrument P to prevent ink from spreading.
