That is, the lifting unit 560 may adjust the height between the printing unit 410 and the printing medium by moving the lifting block 510 upward or downward according to the movement of the operation button 521 .

Here, referring to FIGS. 5A and 7A , there is no significant difference in height between the lower surface of the first frame 511 and the lower surface of the printing unit 410 . Precisely, the height difference between the lower surface of the first frame 511 and the printing unit 410 maintains a distance as much as Z1 to be discussed below.

Referring now to FIGS. 5B and 7B , after the height adjustment module 500 operates, the first frame 511 is in a lowered state, so the lower surface of the first frame 511 and the lower end of the printing unit 410 . The height difference between the faces becomes larger. Precisely, the height difference between the lower surface of the first frame 511 and the printing unit 410 was adjusted to maintain a distance as much as Z2 to be discussed below.

Even in this case, since the first roller 530 and the second roller 540 are connected to the lower portion of the first frame 511 , when they descend together, the surface of the print medium can be smoothly moved.

6A and 6B are side views before and after the elevation of the height adjustment module 500 are disclosed.

In this drawing, the print media are denoted as G1 and G2, which may be classified according to the material of the print media.

For example, the printing medium G1 may be made of a relatively flat or hard material, for example, paper, fabric, wall, wooden board, or the like. In addition, the printing medium G2 may be made of a soft material, for example, human skin, rubber, etc., may be a material whose surface can be deformed during the printing process.

Also, in this figure, the distances between the printing unit 410 and the print medium are indicated by Z1 and Z2, which may be defined as the distance at which the printing unit 410 can print on the print medium. Hereinafter, Z1 and Z2 will be defined and described as a printing distance or a jetting distance.

Referring to FIG. 6A , when the printing medium G1 is made of a relatively flat or hard material, the printing unit 410 and the printing medium G1 in order for the printing unit 410 to smoothly print on the printing medium G1. The distance between them should maintain the first jetting distance Z1. At this time, the user may position the lifting block 510 on the lower inner side of the device body 300 without descending.

Referring to FIG. 6B , when the printing medium G2 is made of a soft material and deformation occurs during the printing process, the printing unit 410 and the printing medium in order to smoothly print on the printing medium G1. The distance between (G1) should maintain the second jetting distance (Z2). This is in consideration of the surface deformation of the print medium G2. At this time, the user must lower the lifting block 510 .

Specifically, the user may lower the lifting block 510 by operating the operation button 521 as described above. As the elevating block 510 descends, the first roller 530 and the second roller 540 may also descend. However, as shown in FIGS. 5B and 7B , the printing unit 410 may not descend.

Accordingly, the jetting distance between the printing unit 410 and the print medium G2 is adjusted from Z1 to Z2. Then, when the user holds the printing device 100 and moves along the surface of the printing medium, even if a change occurs in the surface of the printing medium, the jetting distance Z2 is maintained between the printing unit 410 and the printing medium G2. You can print smoothly.

Referring to FIGS. 9A and 9B , the operation of the printer apparatus according to a surface change for each print medium is shown.

Referring to Figure 9a, if the print medium (G1) is a relatively flat or hard material, the user does not operate the height adjustment module 500, but hold the printing device 100 and move it in the direction of the arrow to change the design to the print medium ( G1) can be printed. P1 indicated in this figure indicates a printing area and indicates an area in which the printing unit 410 is spaced apart from each other by a predetermined interval to print the design by injecting ink into the printing medium G1.

At this time, the first roller 530 and the second roller 540 smooth the surface movement of the print medium G1. Here, the distance maintained between the printing unit 410 and the print medium G1 may be the first jetting distance Z1 illustrated in FIG. 6A .

Referring to FIG. 9B , when the printing device 100 is moved in the direction of the arrow when the printing medium G2 is made of a soft material, the printing medium G2 is deformed by the user's pressing force. In particular, when the first roller 530 and the second roller 540 move along the surface of the print medium G2, the pressure may be severe.

In this drawing, the user lowered the lifting block 510 by operating the height adjustment module 500 in consideration of the material of the print medium G2. Accordingly, even if deformation occurs in the print medium G2, the degree of deformation is reflected, and thus a predetermined distance is ultimately maintained between the printing unit 410 and the print medium G2 in the print area P2.

P2 indicated in this figure indicates a printing area, and indicates an area in which the printing unit 410 is spaced apart from each other by a predetermined interval by injecting ink into the printing medium G2 to print the design.

According to the adjustment of the jetting distance Z2, the printing area P1 illustrated in FIG. 9A and the printing area P2 illustrated in FIG. 9B may have a relatively equal distance between the printing unit 410 and the print medium.

According to at least one of the above-described embodiments of the present invention, the height between the printing unit 410 of the ink member 400 and the printing medium may be adjusted in consideration of the material of the printing medium. Accordingly, there is an advantage in that the design can be smoothly printed on the surface by forming the printing area in consideration of the surface deformation according to the material of the printing medium that may occur during the printing process.
