FIG. DETAILED DESCRIPTION OF THE INVENTION

[0026] Although the present invention can be embodied in various modifications, specific embodiments are illustrated in the drawings and described in detail, but it is not intended to limit the present invention to the specific embodiments, and it should be understood that the present invention includes all modifications, equivalents, and alternatives within the spirit and technical scope of the present invention.

[0027] In the drawings, like elements are denoted by like reference numerals. In describing the present invention, if it is determined that a detailed description of related publicly known techniques may obscure the gist of the present invention, the detailed description will be omitted.

[0028] The present invention uses image processing technology to segment the nail area based on the captured image of the hand, and allows a nail art image selected by the user to be printed on the segmented nail area or an artificial nail to be attached to the nail.

[0029] As shown in FIGS. 1 and 2, the nail art device according to the present invention includes a nail measuring device 10 for measuring the shape of a nail input through a hand input port 80 formed on the front of a roughly kiosk-shaped main body to obtain measurement data for printing various colors and patterns on the nails; a touch screen 20 for displaying the nail shape measured by the nail measuring device 10 and displaying a nail design desired by a user and for inputting information; a printer 30 for printing a nail design according to the nail shape measured by the nail measuring device 10; a sticker dispenser 40 for dispensing nail stickers S selected by the user through the touch screen 20; an artificial nail dispenser 50 for dispensing artificial nails A selected by the user through the touch screen 20; a payment module 70 for settling the cost of nail art; and a controller 90 for controlling all of the above components.

[0030] The nail measuring device 10 is a device for measuring the shape of a nail, and may include a camera or a 3D scanner for taking an image of the nail, a lamp for providing illumination to the hand inserted into the hand insertion slot 80, and a software S / W program for processing the image taken by the camera or the 3D scanner and extracting only the nail area. The image processing technology is applied to the image of the hand taken by the camera using a moire method to separate the nail area, and then the image combined with the nail and printing coordinate information on the printer are provided to the printer so that a nail art image selected by the user can be printed on the user's nail.

[0031] Although a camera or a three-dimensional scanner has been described as an example of the means for capturing an image of the nail, it is preferable to use a three-dimensional scanner.

[0032] Of course, the image of the nail sensed by the nail measuring device 10 can be displayed on the touch screen 20 so that the user can check it.

[0033] The touch screen 20 is an input / output device that displays not only the image of the nail photographed and extracted by the nail measurement device 10 but also the image of the nail image printed on the nail, and displays various designs of the nail image, allowing the user to select the desired nail image.

[0034] Furthermore, the touch screen 20 not only allows the user to select a desired nail image, but also has a function of inputting information for selecting nail stickers S and artificial nails A supplied from the sticker supply machine 40 and artificial nail supply machine 50 so that they can be sold separately. That is, the nail stickers S and artificial nails A supplied from the sticker supply machine 40 and artificial nail supply machine 50 may be output in a state where they are attached to the user's nails, or may be purchased separately and then attached by the user as desired.

[0035] The main screen of the touch screen 20 includes a nail art gallery where nail tips with designated nail styles, colors, and patterns can be selected, a nail art production process that displays the production process through the selection process of nail styles and patterns, and a purchase screen for nail art materials such as line tapes, beads, and parts.

[0036] Furthermore, the initial screen of the touch screen displays information and necessary information related to using the nail art device for easy understanding.

[0037] Nail art materials also include artificial nails, nail tips, and stickers.

[0038] Nail art production information allows users to change the style, pattern, and color of their choice. There are three basic styles (full coat, gradation, and French), and the color and whether it is illuminated or not can be selected from approximately 40 options, including red, orange, and yellow. Patterns include the latest, trendy, seasonal, and event-related patterns. As shown in Figure 6, the color of the selected pattern can be changed by selecting one or more of the approximately 40 colors and whether it is illuminated or not.

[0039] That is, as shown in FIG. 6, the selection menu display unit 120 displays 10 nail configurations to the user through the preview display unit 121 at the top, allowing the user to immediately apply the configurations, and the configurations can be immediately changed and applied by selecting a color.

[0040] The menu selection button section 122 arranged below the preview display section 121 displays the latest nail art designs, trendy designs, recommended designs, seasonal designs, etc., allowing the user to select a desired event-related pattern.

[0041] Furthermore, a two-tiered color bar display section 123 arranged below the menu selection button section 122 displays a secondary color bar when a primary selection is made, and the primary color display of the color bar display section 123 is displayed in about 10 colors such as red, orange, yellow, green, blue, indigo, purple, black, white, and pink, while the secondary color display is displayed in about 5 to 8 colors that are detailed in relation to the primary color display. The color display configuration as described above can be freely modified as many times as desired according to trends.

[0042] Furthermore, it can be fully understood from the above embodiment that the arrangement of the nail tip display section 124, which displays 10 nail tips in a pack below the color bar display section 123, can be modified as many times as desired by the user.

[0043] The printer 30 is used to print a nail image of a user's desired design on the user's nails, artificial nails, or stickers, and is equipped with a number of paint (or ink) spray nozzles so that it can perform all of the base coating, color coating, and protective coating (varnish) processes typically used in offline nail art.

[0044] For example, the printer may have a total of six head nozzles, including one for base paint, four for color paint, and one for protective paint, and may move up and down, front and back, left and right (Z-axis, X-axis, Y-axis) along the conveying means 31, allowing the printer to print nail images on nails, nail stickers, or artificial nails.

[0045] A curing means 32 is provided on one side of the printer.

[0046] The curing means 32 is a means for curing the paint of the printed nail image and can be configured with vertical UV LED (V-LED) lamps. These vertical lamps (2-3) are modularized with 20 LEDs of approximately 395 nm and are installed on the back of the printer head and on the gantry. By controlling the amount of light to cure the nail image while printing it, the curing time of the base paint, color paint, and protective paint can be shortened and moire (interference fringes) can be removed from the printed material, thereby improving the print quality.

[0047] The sticker dispenser 40 is a device for dispensing nail stickers S to be attached to nails, and the nail stickers dispensed through this device can be sold in a state where they are attached to the user's nails or sold separately.

[0048] The sticker supply machine 40 may be composed of a sticker tray 41 loaded with nail stickers, a tray lifting device 42 for raising and lowering the sticker tray, and a horizontal conveying means 43 for conveying the nail stickers on the sticker tray 41 raised by the tray lifting device 42 to the exit or hand insertion port side.

[0049] The sticker tray 41 is in the shape of a flat plate, and nail stickers are stacked in multiple layers on top of it. The loaded nail stickers are then discharged to the product outlet (or manual input port) by a horizontal conveying means 43.

[0050] In order to press and supply the ejected nail stickers toward the horizontal conveying means 43, a tray lifting device 42 is provided below the sticker tray 41. The tray lifting device 42 can be modified in various ways, but preferably, as shown in Fig. 2, it can be composed of two rotating bars 42b rotatably provided below the sticker tray 41 and a rotating bar operating means 42m that adjusts the height of the sticker tray by pushing or pulling the lower end of one of the rotating bars.

[0051] In the sticker dispenser 40 configured as described above, when the rotary bar operating means 42m is actuated to operate the rotary bar 42b and raise the sticker tray 41, the topmost nail sticker among the loaded nail stickers is aligned with the discharge outlet, and the horizontal conveying means 43 is actuated to move the nail sticker toward the discharge outlet.

[0052] The rotating bar operating means 42m can be composed of a screw shaft hinged to either side of the rotating bar 42b and a motor that rotates the screw shaft. When the screw shaft is rotated by the motor, the rotating bar is pushed or pulled, thereby changing the erection angle, and as a result, the height of the sticker tray is adjusted.

[0053] As shown in FIG. 2, the horizontal conveying means 43 can be composed of a number of rollers 43a to 43c.

[0054] Roller 43a, which is provided on the top of sticker tray 41, is a cam-type roller with a sticker feed portion having a relatively large diameter formed in one part, as shown in the figure. When the sticker feed portion comes into contact with the sticker and pushes the sticker toward the exit side, rollers 43b to 43c sequentially press the sticker toward the exit side and transport it.

[0055] The artificial nail dispenser 50 is a device for dispensing artificial nails A to be attached to nails, and the artificial nails dispensed by this device can be sold in a state where they are attached to the user's nails or sold separately.

[0056] The artificial nail supplying machine 50 may be composed of an artificial nail loading machine 51 on which the artificial nails A are loaded, and an artificial nail horizontal conveying machine 52 which conveys the artificial nails loaded on the artificial nail loading machine by pressing them toward the front upper and lower conveying loader 60.

[0057] The artificial nail loader 51 is a means for loading artificial nails, and may be a closed loop having multiple storage spaces, or may be an elevator plate that is raised and lowered by an elevator means. The artificial nails stacked or stored on the upper portion of the loader 51 are pushed out by the horizontal artificial nail conveyor 52 and moved to the discharge port side.

[0058] The artificial nail horizontal conveyor 52 may be configured by providing a push plate for pushing out the artificial nails on one side of a horizontally moving means such as an LM guide.

[0059] An upper and lower transport loader 60 is provided on one side of the artificial nail supplying machine 50.

[0060] The vertical conveying loader 60 includes a product support plate 61 that supports the artificial nails pushed out by the horizontal artificial nail conveyor, and an elevating means 62 that raises and lowers the product support plate 61.

[0061] The lifting means 62 can be implemented in various ways. For example, as shown in Fig. 2, the lifting means 62 is composed of a screw shaft 62s rotatably installed on the bottom surface of the product support plate 61, and a motor 62m for rotating the screw shaft 62s.

[0062] The payment module 70 is a means for paying for the cost of nail art, and may be configured by borrowing one that is usually installed in a vending machine, but as shown in Figure 1, it may also include card slots 71, 72 into which credit cards or cash cards are inserted, or a mobile payment unit 71o, etc.

[0063] As shown in FIG. 1, the hand insertion opening 80 is formed on the front of the nail art device as described above, and the hand insertion opening 80 has a number of grooves formed therein for the fingers to be placed in, thereby stably holding the fingers and preventing the fingers from moving during the process of measuring the nails with the nail measuring device and the process of printing an image on the nails.

[0064] As shown in FIG. 4, the hand insertion port 80 has seven finger insertion ports, and for the left hand, the middle finger is inserted into port 1, the ring finger into port 2, the index finger into port 3, the little finger into port 4, and the thumb into port 7. For the right hand, the middle finger is inserted into port 1, the index finger into port 2, the ring finger into port 3, the little finger into port 5, and the thumb into port 6.

[0065] 5, the hand insertion port 80 is provided with a fixing means for fixing the finger so that it does not move, the fixing means including a first fixing device for fixing the part of the finger adjacent to the palm and a second fixing device for fixing the fingertip, which are actuated by a compression spring to press and fix the finger. In addition, an air tube is provided in the middle part of the finger, and the finger can be fixed by supplying or discharging air into the air tube.

[0066] A nail art method performed by the nail art device configured as above will now be described with reference to FIG.

[0067] As shown in FIG. 3, the nail art method includes a hand image capturing step S1 in which a user's hand is captured with a camera or scanner constituting a nail measurement device to obtain an image of the hand and hand position information; a hand region extracting step S2 in which a background region excluding the hand is removed from the image data captured in the hand image capturing step S1 to extract the edge of the hand; a nail region extracting step S3 in which an image data cleansing program is used to extract only the portion with the nail from the hand region extracted in the hand region extracting step S2; a nail position information extracting step S4 in which the position of the nail region is extracted from the image extracted in the nail region extracting step S2; an image matching step S5 in which the position information extracted in the nail position information extracting step S4 is used to match an image for nail art previously selected by the user with the region of the nail position information; and an image outputting step S6 in which the image data obtained in the image matching step S5 is transferred to a printer and the printer outputs the image for nail art.

[0068] Of course, before the whole process is carried out, the user can select the desired nail art material via the touch screen.

[0069] In the hand image capturing step S1, the hand is scanned using a camera or a three-dimensional scanner that constitutes the nail measuring device, and a 400×400 size image of the hand and hand position information can be obtained.

[0070] The data is verified by performing 3D mesh modeling using the hand position information acquired in the hand image capturing step S1. The Z-axis value (height data) of the verified 3D mesh data is corrected to a desired size, and the hand region is extracted from the corrected image by image data refinement, which removes the background. Edges are then extracted from the extracted hand region, and a group of nail candidates is selected by region matching from a database of hand images.

[0071] After analyzing the selected candidates and extracting nail position information, the nail image and nail color selected by the user are matched using the nail information, and the matched image is converted into a format using printer property information and then transferred to the printer, which prints the nail image directly on the nail or onto a nail sticker or artificial nail based on the transferred information. The nail color information is analyzed using a histogram, and a warning message is displayed if the selected nail color is printed incorrectly.

[0072] The nail art device of the present invention configured as described above includes a communication module, which allows remote updating of printed nail images via a mobile application or a web server, and also allows provision of nail art-related information to users who have signed up as members.
