At this time, if the description continues with simultaneous reference to FIG. 5 for a detailed description of the above-described needle cartridge 141, in FIG. 141) is shown in an exploded view.

As shown in A and B of FIG. 5, the needle cartridge 141 may include one or more needle units 1411 having a predetermined length. Specifically, the above-described needle unit 1411 is a tattoo needle, A single needle may be used, but two or more fine needles may be used as a bundle, and are inserted into the pigment discharge line 1413a formed in the pigment feed 1413 to allow the discharged pigment to penetrate the skin of the treatment subject function will be performed.

In addition, the aforementioned needle cartridge 141 includes a dye guiding nozzle 1412 that communicates with the aforementioned dye cartridge 132 and forms a transport path for supplying the dye from the color cartridge 132 to the needle unit 1411. do.

Specifically, the dye inducing nozzle 1412 described above may be supplied in three types for the purpose of controlling the amount of dye supply according to the operator's technique.

Referring to FIG. 10, FIG. 10 shows an example of supplying a syringe type/screw type/fountain pen feed type of a dye inducing nozzle 1412, and in FIG. 10 A, B, and C, the dye inducing nozzle 1412 ), and in A', B', and C' of FIG. 10, cross-sectional views of the dye inducing nozzles 1412 of A, B, and C described above can be seen, and the shape difference of the nozzle according to each type is it can be seen that there is

Specifically, A and A' are syringe-type pigment inducing nozzles 1412, B and B' are screw-type pigment inducing nozzles 1412, and C and C' are fountain pen feed-type pigment inducing nozzles 1412. You will be able to understand.

Meanwhile, the above-described needle cartridge 141 may include a second elastic spring 1414 mounted in an area between the dye guide nozzle 1412 and the dye feed 1413 to provide elastic force to the needle unit 1411. It will be understood that the 2 elastic springs 1414 are provided as a configuration for outputting the pigment stored in the color feed 1413 to the outside of the nozzle.

Referring next to FIG. 9 , it can be seen that an example of a fastening method of the aforementioned needle cartridge 141 and the color cartridge 132 is shown in FIG. 9 .

That is, the color guide nozzle 1412 is inserted into the bonding area of the color cartridge 132 to transfer the color stored in the color cartridge 132 to the color feed 1413, and the color transferred to the color feed 1413 is fed to the color feed 1413. ) can be provided to the needle unit 1411 along the dye discharge line 1413a provided in the form of a small hole.

At this time, in a more preferred embodiment of the present invention, in order to prevent the outflow of the color transferred from the color cartridge 132 to the color feed, as shown in FIG. (1415) may be further included.

Specifically, the inner surface of the pigment detachment preventing member 1415 is provided with a shape corresponding to the outer surface of the pigment inducing nozzle 1412. For example, the inner surface of the pigment detachment preventing member 1415 has a hexagonal shape. , the outer shape of the pigment inducing nozzle 1412 is provided to have the size and shape of a hexagonal column that can be fitted into the inner surface of the pigment detachment preventing member 1415.

That is, according to this, the needle cartridge 141 and the color cartridge 132 are tightly coupled to each other by the fitting of the color guide nozzle 1412 of the needle cartridge 141 and the color separation preventing member 1415 of the color cartridge 132. It becomes.

On the other hand, in this fastening structure, the needle cartridge 141 and the second shell, which will be described later, have a screw coupling method, and when rotating to the left or right for fastening or separating, the color cartridge 132 and the needle cartridge 141 move.
