According to some embodiments of the present disclosure, the control unit 360 may determine the size of the printing area based on information about the estimated vertical length of the nail and information about the estimated width of the nail.

Specifically, the control unit 360 may determine the vertical length of the printing area based on information about the estimated vertical length of the nail, and determine the horizontal length of the printing area based on information about the estimated width of the nail.

In the present disclosure, the size of the user's nail may be determined using information obtained through the camera of the user terminal. Additionally, the size of the printing area may be determined based on the size of the user's nail determined in the user terminal. Accordingly, the nail art device 400 does not need to be equipped with a camera to determine the size of the printing area where nail art will be performed.

Meanwhile, the control unit 360 may determine the position of the printing area based on the width of the insert (eg, the user's finger or toe) inserted into the nail holder module 100. Here, the control unit 360 can determine the position of the printing area by adjusting the position of the vertical center line of the printing area. Here, the vertical center line may be an imaginary line that vertically crosses the center point of the printing area.

Specifically, the control unit 360 determines the width of the insert inserted into the nail holder module 100 from the point corresponding to the first of the two points in time when the position of the vertical center line of the printing area changes by more than a preset threshold value. The position of the printing area may be determined to be placed at a position moved by half in the second direction (Y).

When the position of the printing area is determined as described above, the virtual vertical line passing through the center of the printing area in the vertical direction is an insert inserted into the nail holder module 100 (e.g., the user's finger or toe). ) may coincide with an imaginary vertical line passing through the center of the vertical direction.

If the printing area is placed at a preset location, the image for nail art may not be printed properly. This is because the insertion location of the user's finger or toe may change, and the size of the finger or toe varies depending on the user. However, this problem can be solved when the position of the center line is determined based on the width of the user's fingers or toes, as in the present disclosure.

Meanwhile, when the size and position of the printing area are determined in step S140, the control unit 360 drives the printer through the interface unit 363 by sending a second drive control signal that moves the printer driving module to print an image in the printing area. It can be transmitted to the module 200. Here, in conjunction with the second drive control signal being transmitted to the printer drive module 200, the control unit 360 operates the printer module 300 to print an image corresponding to the image data received through the communication unit 362. can be controlled. Accordingly, the printer driving module 200 can move the printer module 300 based on the second driving control signal, and the printer module 300 can print an image corresponding to the image data while moving in the second direction (Y). It becomes possible. Here, when the printer module 300 prints an image corresponding to image data, printing may be performed based on the size and location of the image input to the user terminal.

FIG. 32 is a diagram illustrating an example of a method for obtaining estimated length information of a user's nail through a user terminal according to some embodiments of the present disclosure. In relation to FIG. 32 , contents that overlap with those described above with respect to FIGS. 1 to 31 will not be described again and will be described below focusing on differences.

Referring to FIG. 32, a user can capture an image including finger or toe nails through a user terminal owned by the user. In this case, the user terminal (U) can obtain information on the estimated length of the nail. Here, the estimated nail length information may be generated by analyzing an image containing the user's nails captured by the camera of the user terminal (U).

According to some embodiments of the present disclosure, when an application for obtaining estimated nail length information is executed, the user terminal (U) may activate the camera and capture an image through the camera. The user terminal (U) may display on the screen an image (or preview image) including the nail of the user's finger or toe captured through a camera. Here, two vertical lines (L1, L2) and two horizontal lines (L3, L4) may be displayed on the screen where the image containing the nail is displayed.

In the present disclosure, each of the two vertical lines L1 and L2 may be able to move in the vertical direction on the image according to the user's touch input. Additionally, each of the two horizontal lines L3 and L4 may be able to move in the horizontal direction on the image according to the user's touch input.

The user can change the positions of the two vertical lines (L1, L2) and the two horizontal lines (L3, L4) on the screen where the image containing the user's nail is displayed and place them at the distal end of the user's nail.

Specifically, the user places one of the two vertical lines (L1, L2) on one horizontal end of the nail, and the other of the two vertical lines (L1, L2) on the other horizontal end of the nail. (L2) can be placed. Then, the user places one of the two horizontal lines (L3, L4) (L3) on one vertical end of the nail, and the other of the two horizontal lines (L3, L4) on the other vertical end of the nail ( L4) can be placed. Then, when the user clicks the measurement button, the user terminal (U) can obtain information on the estimated length of the user's nail based on the positions of the two vertical lines (L1, L2) and the two horizontal lines (L3, L4).

More specifically, the user terminal (U) may calculate information about the estimated vertical length based on the positions of the two horizontal lines (L3, L4) and the estimated width based on the positions of the two vertical lines (L1, L2). Information about can be calculated. Here, the estimated width can be calculated based on the first distance (X1) between two vertical lines (L1, L2) and the second distance between the camera and the nail, and the estimated vertical length can be calculated based on the two horizontal lines (L3, L4) It may be calculated based on the third distance Y1 and the second distance. Here, the second distance may be calculated through an infrared sensor provided in the user terminal (U) or by analyzing the image. However, it is not limited to this.

As described above in FIG. 32, the size of the user's nail is calculated by analyzing the image captured through the user terminal, and the printer module 300 receives the estimated nail length information through the communication unit 362, so that the nail art device (400) does not require a separate camera.

FIG. 33 is a diagram illustrating an example of a method for determining the width of a user's fingers or toes according to some embodiments of the present disclosure. In relation to FIG. 33 , content that overlaps with what was described above with respect to FIGS. 1 to 32 will not be described again and will be described below focusing on the differences.

Referring to FIG. 33, a pair of light reflection plates 140 may be disposed on a pair of second holder blocks 130 provided in the nail holder module 100. The user can mount the nail holder module 100 on the holder mounting unit provided in the nail drive module 200 while inserting his or her finger or toe into the nail holder module 100. Here, the user can insert the nail so that one end (the end of the finger) in the vertical direction of the nail is at the position of the indicator line (E). And, when printing is performed, the printing module 300 may transmit a first drive control signal to the printer drive module 200. As a result, the printer driving module 200 can primarily move the printer module 300 in the second direction (Y). While the printer driving module 200 primarily moves the printer module 300 in the second direction (Y), the control unit 360 of the printer module 300 detects the sensing value (S) obtained through the detection sensor 364. ) changes can be detected. The control unit 360 may recognize two times (t1, t2) when the sensing value (S) changes by more than a preset threshold value (V).

Specifically, the control unit 360 sets the sensing value (S) to a preset value (V) at a first time point (t1) when the sensing value (S) increases above the preset value (V) and then decreases, and after the first time point (t1), the sensing value (S) increases to a preset value (V). It is possible to recognize the second time point (t2) when (V) rises again. Additionally, the control unit 360 may recognize information on the time it takes for the printing module 300 to move using the first time point t1 and the second time point t2. The control unit 360 controls the user's finger or toe (nail holder module 100) based on the time information recognized using the first time point (t1) and the second time point (t2) and the movement speed information of the printer module stored in the storage unit. ) can be calculated.

Meanwhile, the control unit 360 can determine the size and location of the printing area R. Here, the size of the printing area R may be determined based on the estimated length information of the user's nail, which is information received from the user terminal. Additionally, the location of the printing area (R) may be determined based on the width (d) of the user's fingers or toes.

Specifically, when determining the position of the printing area R, the control unit 360 may determine the position of the printing area R by adjusting the position of the vertical center line C of the printing area.

More specifically, the control unit 360 determines that the position of the vertical center line (C) of the printing area is the width of the user's finger or toe from the point corresponding to the first time point (t1), which is the first of the two time points (t1, t2). The position of the printing area may be determined to be positioned at a position moved in the second direction (Y) by half of (d).

Meanwhile, since the printer module 300 receives estimated nail length information from the user terminal and determines the printing area, nail art printing can be properly performed even if the user's nails are long in the vertical direction.

Specifically, the user can insert the nail so that one vertical end of the nail (the part connected to the finger) is at the position of the indicator line (E). Additionally, the printer module 300 can perform printing in the nail printing area. In this case, the printer driving module may move the printer module 300 in the first direction (X) and the second direction (Y). Therefore, nail printing can be performed properly even if the user's nails are long in the vertical direction.

Meanwhile, in a conventional nail art device, when a user inserts a finger into the nail art device, a camera is placed inside the nail art device.

Users can confirm that the nail has been properly inserted through the video captured by the camera, and the nail art device operates by printing designs on the nail using the video captured by the camera. However, in the case of this structure, there is a problem that the price of the nail art device is expensive because a camera is absolutely necessary.

The nail holder module 100 according to an embodiment of the present disclosure is capable of stably fixing the user's nails, and allows the user to The width of the finger or toe (insert inserted into the nail holder module 100) can be accurately confirmed. And, using this, the printing area where nail printing will be performed can be determined. Accordingly, compared to conventional nail art devices, there is no need for a camera, which reduces product cost and improves usability.

In addition, the conventional nail art device has a built-in printer and cannot be used separately, but the printer module 300 according to the embodiment of the present disclosure can be used as the nail art device 400 when mounted on the printer driving module 200. And, when used independently without being combined with the printer driving module 200, it can be used like a hand-held printer. In other words, designs can be printed not only on nail art, but also on paper, fabric, etc., and when used on the user's skin, designs such as tattoos can be printed, so the usability of the printer module 300 itself has been improved compared to the prior art.

According to at least one of the above-described embodiments of the present invention, the printing start point is not fixed to a preset point, so it is not affected even if the size of the user's finger or toe actually inserted into the nail holder module 100 changes. Nail printing can be done starting from the center of the nail. Therefore, nail printing can be performed precisely even though there is no camera.

In the present disclosure, the nail holder module, printer drive module, and printer module are not limited to the configuration and method of some of the embodiments described above, and the several embodiments may be modified so that various modifications can be made to all or all of the embodiments. Some of them may be selectively combined.
