The finger stopper 170 may include a central indicating groove recessed inward in the central portion. Here, the central indication groove may serve to show the central axis so that the user's finger can be placed in the center. That is, the user can place the finger on the nail holder module 100 by aligning the center of the finger with the central indicating groove.

A conventional nail art device has a camera disposed inside. Therefore, when a user inserts a finger into the nail art device, the user has to check whether the nail has been properly inserted through an image captured by a camera and move the finger so that the center of the nail is located on the internal central axis. However, in the case of this structure, there is a problem in that it increases the price of the nail art device because a camera is absolutely necessary.

However, according to the present disclosure, when the central indicating groove is located in the center of the finger stopper 170 and the nail holder module 100 has a structure that is detachable from the nail art device 200, the user can use the nail holder module 100 without a camera. You can position your fingers where you need them inside. Additionally, since the nail art device 200 does not need a camera to photograph the interior, the manufacturing cost of the nail art device 200 can be lowered.

The upper housing 310 and the base plate 340 maintain an elevated state due to the elastic force caused by the lifting spring 442 of the lifting guide unit 440, which will be reviewed below, but additionally, the support link 431 is used to maintain the raised position of the base plate 340. It is possible to prevent the upper housing 310 and the base plate 340 from descending while supporting the lower surface in contact.

Thereafter, when the lever unit 410 is operated again to move the lever body 411 in the direction of arrow S1, the link shaft 431a connected to the lever body 411 also moves in the direction of arrow S1. In this case, the link spring 433 pushes the lower part of the support link 431, and the support link 431 rotates downward and lies down. At this time, when the upper housing 310 and the base plate 340 are lowered, as shown in FIG. 21, the link pressing block 435 presses the support link 431 to rotate downward and remain in a lying state. Afterwards, as shown in FIG. 19, as the upper housing 310 descends, the lower part of the base plate 340 contacts the lying support link 431 and presses the support link 431. Through this structure, the support link 431 can be maintained in a lying state while the upper housing 310 is lowered.

Meanwhile, referring to FIGS. 11, 23, and 24, the lifting guide unit 440 is connected and disposed between the upper housing 310 and the lower housing 350, and can guide the lifting of the upper housing 310. .

This lifting guide unit 440 may include a first lifting guide part 441 and a second lifting guide part 446.

Referring to FIG. 23, the first lifting guide unit 441 is connected and disposed between the lower housing 350 and the upper housing 310, and can guide the lifting of the upper housing 310. At this time, the first lifting guide unit 441 may apply elastic force upward to the upper housing 310 to maintain the upper housing 310 in an elevated state.

This first lifting guide unit 441 may include a lower pole 445, an upper pole 443, and a lifting spring 442.

A plurality of lower poles 445 may be disposed at the edge of the lower housing 350. In some embodiments of the present disclosure, four may be arranged, but it is not necessarily limited thereto.

The number of upper poles 443 corresponding to the lower poles 445 may be arranged at the edge of the base plate 340, and a lifting line 444 may be formed inside in the height direction (Z). The upper end of the upper pole 443 may be coupled to the upper plate 320 by a bolt 443a (FIG. 11). Referring to FIG. 9, a bolt 443a is fastened to a bolt hole formed in the upper plate 320, and the upper pole 443 can be coupled to the upper plate 320.

The lifting spring 442 may be disposed between the lifting line 444 and the upper part of the lower pole 445. A spring support 445b (see FIG. 21) protrudes from the upper part of the lower pole 445 to prevent the lifting spring 442 from being separated.

Here, the lower pole 445 can move in the vertical direction (Z) along the lifting line 444 formed inside the upper pool.

That is, when the upper housing 310 rises, the lifting spring 442 applies elastic force to the upper pole 443 and the upper pole 443 pushes up the upper plate 320 so that the upper housing 310 can rise. do. And the elastic force of the lifting spring 442 maintains the upper housing 310 in an elevated state.

When the upper housing 310 is lowered, the lower pole 445 is input into the lifting line 444 formed inside the upper pole 443. When the upper housing 310 covers the lower housing 350 and is lowered, the upper pole 443 and the lower pole 445 exist in an overlapping state.

Referring to FIG. 24, the second lifting guide unit 446 may be connected and disposed between the lower housing 350 and the upper housing 310, and may guide the lifting and lowering of the upper housing 310. The second lifting guide unit 446 may guide the lifting of the upper housing 310 by assisting the first lifting guide unit 441.

This second lifting guide unit 446 may include a sub-elevating beam 448, a sub-pole 449, and a sub-slider 447.

The sub-elevating beam 448 may be disposed between the plurality of lower poles 445 in the lower housing 350. Referring to FIG. 21, it can be seen that the sub-elevating beam 448 is disposed between the lower housing 350 and the lower pole 445. The lower part of the sub-elevating beam 448 may be fixed to the lower housing 350 by a pair of fixing pieces 448a. A pair of fixing pieces 448a are connected to the sub-elevating beam 448, one fixing piece 448a is disposed on the bottom surface of the lower housing 350 (see FIG. 10), and the other fixing piece is (448a) is disposed on the upper surface of the lower housing 350 (see FIG. 21) and can fix the sub-elevating beam 448 to the lower housing 350.

The subpole 449 may be disposed between a plurality of upper poles 443 on the base plate 340, and the upper end of the subpole 449 may be coupled to the upper plate 320 by a bolt 449a. Also, a sub-elevating hole 449d is formed in the longitudinal direction inside the sub-pole 449, and a sub-elevating beam 448 can be inserted and disposed.

The sub-slider 447 may be coupled to the sub-elevating beam 448 and may have a shape corresponding to the internal shape of the sub-elevating hole 449d. And the size of the sub-slider 447 and the size of the sub-elevating hole 449d may generally correspond. For example, when the sub-elevating hole 449d has a cylindrical shape, the sub-slider 447 may have a cylindrical shape, and in this case, the outer diameter of the sub-slider 447 and the inner diameter of the sub-elevating hole may be substantially the same.

This corresponding structure can guide the sub-elevating beam 448 to move in the vertical direction (Z) inside the sub-elevating hole 449d. That is, since the sub-slider 447 is guided and moves along the inner surface of the sub-elevating hole 449d, shaking and vibration, etc., can be alleviated during the process of raising and lowering the upper housing 310.

Through the configuration of the lifting guide unit 440 described above, the upper housing 310 can rise and fall in the vertical direction (Z) with respect to the lower housing 350, and the upper housing 310 can also be raised and lowered by the elastic force of the lifting spring 442. The housing 310 may maintain an elevated state.

Meanwhile, referring to FIGS. 12 to 18 and 25 to 36, the nail printer module 1200 may be placed inside the module housing 300 and print a design on the user's nail.

In some embodiments of the present disclosure, the nail printer module 1200 includes a capping unit 500, a wiping unit 600, a spitting unit 650, a moving member 700, a tolerance removing means 1000, and a cartridge member 1100. ) may include.

The capping portion 500 may be disposed inside the module housing 300 and may cap the print head of the ink cartridge. Specifically, the capping portion 500 may be disposed on one side of the base plate 340 with the nail input portion 360 as a reference at the upper part of the base plate 340. The capping unit 500 may perform the function of storing the print head of the ink cartridge.

The wiping unit 600 may be disposed inside the module housing 300 and can remove ink remaining on the print head of the ink cartridge before or/and after operation of the ink cartridge. Specifically, the wiping unit 600 may be disposed on the other side of the base plate 340 with the nail input unit 360 as a reference at the top of the base plate 340.

The spitting unit 650 may be disposed inside the module housing 300 and can remove ink ejected from the print head of the ink cartridge before or/and after operation of the ink cartridge. Specifically, the spitting unit 650 may be disposed below the wiping unit 600. The control unit (P) can perform wiping and spitting to maintain the quality of the design printed by the print head of the ink cartridge.

The moving member 700 can be placed inside the module housing 300 and can move the ink cartridge. Specifically, the moving member 700 may be disposed on the base plate 340 and may move the ink cartridge in the first direction (X) and the second direction (Y).

First, referring to FIGS. 13 to 15, the capping portion 500 according to some embodiments of the present disclosure includes a capping base 510, a capping block 520, a capping locking portion 523, a capping guard 550, It may include a capping plate 560, a pressure adjustment hole 562, a pressure adjustment plate 570, a pressure adjustment line 571, a capping spring 540, and a capping elevation unit 530.

The capping base 510 may be placed on one side of the base plate 340 inside the module housing 300, and may have a predetermined space formed inside and an open top.

The capping block 520 may be placed inside the capping base 510.

The capping locking portion 523 may be placed on one upper side of the camping block and may be provided to be caught on the beam bracket 1110 of the cartridge member 1100.

The capping guard 550 may be disposed to protrude upward from the top of the capping block 520 and may cap the edge of the print head located below the ink cartridge. In an embodiment of the present disclosure, the capping guard 550 may be made of an elastic material such as rubber.

The capping plate 560 may be placed inside the capping guard 550 and may cap the center of the printhead.

The pressure adjustment hole 562 may be formed to penetrate the capping plate 560.

The pressure regulating plate 570 may be disposed below the capping plate 560.

The pressure control line 571 may be formed concavely in the pressure control plate 570. On one side of the pressure control line 571, a first through groove 571a communicating with the outside may be formed at the edge of the pressure control plate 570, and on the other side, a second through groove communicating with the pressure control hole 562 ( 571b) can be formed. Here, the pressure control line 571 may be formed in a ring shape bent a plurality of times between the first through hole 571a and the second through hole groove 571b.

When capping the print head of an ink cartridge with the capping guard 550 and the capping plate 560, the air in the capping area may expand due to heating of the print head and the pressure may increase. In this case, the shape of the elastic capping guard 550 may be deformed and air may escape, which prevents the print head from being capped smoothly.

Therefore, it is necessary to ensure that the capping guard 550 and the capping plate 560 maintain capping the printhead by allowing air to escape from the capping area through a designated path. To achieve this purpose, a pressure control hole 562 is formed in the capping plate 560, and air is allowed to pass through the pressure control hole 562 and be discharged to the outside through the pressure control line 571.

At this time, the pressure control line 571 is formed in a ring shape bent multiple times to reduce the possibility of exchange between the internal air and external air in the capping area, thereby alleviating the phenomenon of the print head drying out.

The capping spring 540 may be disposed between the capping base 510 and the capping block 520, and may apply an elastic force to the capping block 520 in the front direction B1 of the base plate 340.

That is, the capping block 520 is pushed to the front side of the capping base 510 by the elastic force of the capping spring 540.

The capping elevation unit 530 may be disposed in connection with the capping base 510 and the capping block 520, and may elevate the capping block 520.

This capping lifting part 530 may include an inclined groove 531 and a capping lifting pin 532.

The inclined groove 531 may be formed to slope downward from the side of the capping base 510 toward the front direction B1 of the base plate 340.

The capping lifting pin 532 may be placed on the side of the capping block 520 and may be inserted into and placed in the inclined groove 531.

Accordingly, when the capping lifting pin 532 moves in the front direction B1 along the inclined groove 531, the capping block 520 is positioned in a slightly lowered state inside the capping base 510. The lowering of the capping block 520 occurs naturally because the capping spring 540 applies elastic force to the capping block 520.

Conversely, when the capping lifting pin 532 moves in the rear direction (B2) along the inclined groove 531, the capping block 520 is positioned in a slightly elevated state inside the capping base 510. The capping block 520 is raised by being caught by the capping locking portion 523 on the beam bracket 1110 of the cartridge member 1100. That is, when the moving member 700 moves in the rear direction (B2), the capping block 520 rises.

The operation method of the capping unit 500 is as follows.

First of all, do not cap the print head of the ink cartridge while it is printing a design on your nail. In this case, the capping guard 550 and capping plate 560 should not interfere with the movement of the ink cartridge. Therefore, it is necessary to lower the capping block 520 to the inner lower side of the capping base 510 to lower the height of the capping guard 550 and the capping plate 560.

When the cartridge member 1100 is not caught on the beam bracket 1110, the capping spring 540 applies elastic force to the capping block 520, so the capping lifting pin 532 of the capping block 520 naturally moves into the inclined groove 531. ) is lowered and the height of the capping block 520 is lowered.

After the ink cartridge has completed printing the design on the nail, the print head must be capped and stored. In this case, the height of the capping guard 550 and capping plate 560 must be increased to cover the print head.

At this time, referring to FIG. 15, the moving member 700 first moves forward (F1) and then moves laterally (F2) to move the cartridge receiving portion 974 to the upper part of the capping base 510. In this case, the capping engaging portion 523 is located and caught between the beam brackets 1110 formed on the cartridge member 1100 of the moving member 700.

Thereafter, when the moving member 700 moves backward (F3), the capping lifting pin 532 of the capping block 520 moves upward (F4) along the inclined groove 531, and the capping guard 550 and the cap The finger plate 560 rises to the print head and caps the print head.

Meanwhile, referring to FIGS. 16 to 18, the wiping unit 600 according to an embodiment of the present disclosure includes a wiping base 610, a wiping block 620, a wiping stopper 623, and a wiper 630. , may include a wiper casing 631 and a wiper spring 640.

The wiping base 610 may be placed on the other side of the base plate 340 inside the module housing 300, and may have a predetermined space formed inside and an open top.

The wiper casing 631 may be fixed and disposed on the inner front side of the wiping base 610. The upper part of the wiper casing 631 may be open, and a lower plate 631a may be connected to the lower part of the wiper casing 631, and the lower plate 631a may be fastened to the wiping base 610 with a bolt (not shown). and can be fixed.

The wiper 630 may be supported and disposed on the inside of the wiper casing 631 by the wiper fixing bar 633, and when the print head of the ink cartridge moves in the forward and backward direction (Y) by the moving member 700, The wiper 630 can remove ink remaining on the surface of the printhead by wiping. In the embodiment of the present disclosure, the wiper 630 may be made of an elastic material such as rubber, but is not necessarily limited thereto.

The wiping block 620 may be placed inside the wiping base 610, and a casing detachment groove 624 through which the wiper casing 631 may be detached may be formed on the front part. When the wiping block 620 moves in the front direction C1, the wiper casing 631 can be accommodated in the casing detachment groove 624. Referring to FIG. 16, it can be seen that the wiper casing 631 is accommodated in the casing detachment groove 624. If the wiping block 620 moves toward the rear (C2), the wiper casing 631 may be separated from the casing detachment groove 624.

The wiping catch portion 623 may be disposed on one upper side of the wiping block 620, is caught on the beam bracket 1110 of the cartridge member 1100, and is connected to the cartridge receiving portion 974 of the moving member 700. We can move together.

The wiper spring 640 may be disposed between the wiping base 610 and the wiping block 620, and the wiper spring 640 may apply elastic force to the wiping block 620. Accordingly, the wiping block 620 remains moved in the front direction C1 by elastic force, as shown in FIG. 16, before the wiping locking portion 623 is caught by the beam bracket 1110.

Meanwhile, the spitting part 650 may include a sponge 651 and a suction pad 653.

The sponge 651 may be disposed on the front side of the wiper 630 inside the wiper casing 631, and the sponge 651 may absorb ink ejected from the print head.

The suction pad 653 may be disposed below the sponge 651 in the wiper casing 631 and may adsorb ink discharged from the sponge 651. Referring to FIG. 17, it can be seen that the suction pad 653 is disposed at the bottom of the sponge 651. Referring to FIG. 18, the suction pad 653 is attached to the lower plate 631a formed on the wiper casing 631. It can be placed at the bottom of .

The operation method of the wiping unit 600 and spitting unit 650 is as follows.

First, while the ink cartridge is printing a design on the nail, the wiping unit 600 and spitting unit 650 should not interfere with the movement of the ink cartridge. Accordingly, the wiping block 620 is pushed to the inner front side of the wiping base 610 by the elastic force of the wiper spring 640.

Since the size of the nail is small, the distance that the ink cartridge actually moves along the left and right direction (X) to print the design on the nail is not large, so it does not move to the wiping stop 623.

Before decapping the printhead for the ink cartridge to begin printing designs on nails, residual ink and spurted ink must first be removed from the surface of the printhead before use.

Even after the ink cartridge has completed printing the design on the nail, residual ink and spurted ink must be removed from the surface of the print head after use before capping the print head.

At this time, the print head of the ink cartridge may be spitted followed by wiping, or the wiping may be followed by spitting. This may be determined according to design specifications. In the embodiment of the present disclosure, the order in which the wiping operation is performed after spitting will be described.

At this time, referring to FIG. 18, the moving member 700 first moves forward (R1) and then moves laterally (R2) to move the cartridge receiving portion 974 to the upper part of the wiping base 610. In this case, the wiping locking part 623 is located and caught between the beam brackets 1110 formed on the cartridge member 1100 of the moving member 700. At this time, the print head of the ink cartridge and the wiper casing 631 are aligned in the vertical direction.

Referring to FIG. 16, the rectangular shape of the wiper casing 631 can be formed in a size and shape that can cover the rectangular shape of the print head of a general ink cartridge. The control unit (P) controls the ink cartridge to spit and eject ink.

When the ink cartridge spits and ejects residual ink, the residual ink is ejected into the sponge (651). The sponge 651 absorbs residual ink, and when the ink soaked into the sponge 651 flows downward due to gravity, the ink is absorbed by the suction pad 653. At this time, since the wiper casing 631 has a rectangular shape corresponding to the print head, ink ejected from the print head can be prevented from scattering to the outside of the wiper casing 631.

Thereafter, when the moving member 700 moves backward (R3), the wiping block 620 moves backward (R4) together with the cartridge receiving portion 974.

At this time, the wiper 630 wipes the surface of the print head of the ink cartridge in which the cartridge receiving portion 974 is accommodated and moves backward (R3). Wiping work can be performed multiple times by moving back and forth.

Meanwhile, in some embodiments of the present disclosure, with the nail input unit 360 positioned in the center, a capping unit 500 is provided on one side of the nail input unit 360, and a wiping unit 600 is provided on the other side of the nail input unit 360. ) and the spitting unit 650 can be arranged symmetrically.

Accordingly, when the ink cartridge starts printing a design on the nail, the control unit (P) decapping the ink cartridge in the capping unit 500 and using the moving member 700 to perform the wiping unit 600 and spitting. Move to section 650. Afterwards, the control unit (P) spits the print head of the ink cartridge through control to eject ink, and moves it in the second direction (Y) through a moving member to wipe the ink remaining on the surface of the print head.

After the ink cartridge completes printing the design on the nail, the control unit (P) uses a moving member to move the ink cartridge to the upper part of the wiping unit 600 and spitting unit 650 and then moves it in the first and second directions ( Moves in X, Y) to remove ejected ink and residual ink, moves again to the top of the capping part 500, and then moves in the first and second directions (X, Y) to cap the print head, removing unused ink. The cartridge is stored.

This symmetrical arrangement structure can improve wiping and spitting performance in parallel with the movement of the moving member 700, and prevents interference by lowering the capping part 500 during printing of the ink cartridge, and the capping part 500 when not in use. By raising 500 again to cap the print head, space utilization inside the module housing 300 can be improved.

Meanwhile, referring to FIGS. 25 and 33, the cartridge member 1100 has a detachable ink cartridge, and includes a member body 1140, a cartridge detachment groove 1150, a beam bracket 1110, a link groove 1120, and It may include a cartridge hole 1130.

Here, the timing belt 855 shown in FIG. 30 is expressed as having the uneven portion 855a formed only on a portion, but the uneven portion 855a may be formed on the entire inner surface of the timing belt 855. The uneven portion 855a is engaged with the first and second pulleys 851 and 853, and can allow the timing belt 855 to move when the first pulley 851 rotates.

On the other hand, if the tension of the timing belt 855 is insufficient, the uneven portion 855a of the first pulley 851 and the second pulley 853 may not properly engage, so the timing belt 855 may not move smoothly. . In this case, the movement unit 900 does not move smoothly in the first direction (X).

Therefore, the tension of the timing belt 855 must be maintained so that the uneven portion 855a of the timing belt 855 is well engaged with the first and second pulleys 851 and 853.

The tension adjusting means 870 may be disposed on the device base 1010 and connected to the second pulley 853. The tension adjusting means 870 may apply elastic force to the second pulley 853 to maintain the tension of the timing belt 855.
