- Conventionally, the drawing skill of a user greatly affects the drawing of a nail art by the user himself/herself. Also, even if the drawing skill is high, in the case of drawing on the nails of the user himself/herself, it is difficult to achieve the same drawing accuracy for the nails of the dominant hand and the nails of the hand which is not the dominant hand.
- Moreover, even in the case where a nail technician in a nail salon is to perform drawing, there is a limit on the drawing skill. However, higher accuracy is demanded for drawing.
- In the following, an exemplary embodiment of the present invention will be described with reference to
FIGS. 1 to 5 . - <Configuration of
Nail Forming Device 2> -
FIG. 1 is a schematic diagram showingnail forming device 2 for drawing a nail art (for forming a drawing pattern) onnail 1.Nail forming device 2 isnail forming device 2 for forming a drawing pattern on the surface of nail 1 (or an artificial nail) by using photo-curable resin 3, and includeslight source 4,optical drawing unit 5 for partially curing photo-curable resin 3 by using light that is emitted fromlight source 4, andcontroller 6 for controllinglight source 4 andoptical drawing unit 5. - In the present exemplary embodiment, photo-
curable resin 3 that is cured with UV light is used. -
Light source 4 emits light of a wavelength by which photo-curable resin 3 is cured. Most of the gel nails (photo-curable resin 3) that are currently commercially available need wavelengths ranging from about 365 nm to 410 nm to be cured. Accordingly, in the present exemplary embodiment, a semiconductor laser having a wavelength peak at around 405 nm is used aslight source 4. Also, scanningreflection mirror 7 whose angle of reflection is controlled bycontroller 6 is used asoptical drawing unit 5. - As
scanning reflection mirror 7, a known mirror such as a polygon mirror or a galvanometer mirror is used. - <Configuration of
Reflection Mirror 7> - Next, the configuration of
reflection mirror 7 be described in detail with reference toFIG. 2 . -
Reflection mirror 7 is configured fromactuator 8 andmirror unit 12.Actuator 8 is driven in two axes, and is a MEMS (Micro Electro Mechanical Systems) device that uses an Si substrate and a piezoelectric film. By configuringoptical drawing unit 5 byactuator 8,nail forming device 2 may be miniaturized. -
Actuator 8 includesrectangular support frame 9, rectangularmovable frame 10 disposed on the inside ofsupport frame 9, rectangularmovable unit 11 disposed on the inside ofmovable frame 10,first vibration units 14, andsecond vibration units 16.Movable frame 10 is connected to supportframe 9 byfirst vibration units 14. A pair offirst vibration units 14 is to twist aroundfirst rotation axis 13.Movable unit 11 is connected tomovable frame 10 bysecond vibration units 16.Second vibration units 16 are to twist aroundsecond rotation axis 15 that is orthogonal tofirst rotation axis 13. Additionally,first vibration units 14 are provided withfirst drive units 17.First drive units 17 are connected tocontroller 6. Twisting offirst drive unit 17 is controlled by a control signal fromcontroller 6. Although not shown,first drive unit 17 has a laminate structure where a piezoelectric layer of PZT or the like is interposed between upper and lower electrodes made of Ti, Au or the like. By applying a potential difference between the upper and lower electrodes offirst drive unit 17, twisting offirst vibration unit 14 aroundfirst rotation axis 13 is excited. - Like
first vibration unit 14,second vibration units 16 are provided withsecond drive units 18.Second drive units 18 are connected tocontroller 6. Twisting ofsecond vibration unit 16 aroundsecond rotation axis 15 is excited bysecond drive unit 18. -
Mirror unit 12 is disposed on the surface ofmovable unit 11 ofactuator 8 configured in the above manner, andreflection mirror 7 may scan light emitted bylight source 4 in the directions of two axes. - <Operation of
Nail Forming Device 2> - Next, an operation of
nail forming device 2 will be described with reference toFIG. 1 . -
Controller 6 controlslight source 4 andoptical drawing unit 5.Controller 6 controls the amount of radiation and radiation time of light that is emitted bylight source 4, the angle of reflection ofmirror unit 12 provided toactuator 8, and the like. The surface of photo-curable resin 3 coating the surface ofnail 1 is scanned by the light, and photo-curable resin 3 is partially cured. A drawing pattern is thus formed. - Additionally, as shown in
FIG. 3 , when forming a drawing pattern, if there is a density difference in the drawing pattern, pattern collapse is more likely to occur in an area where the drawing pattern is dense, compared to an area where the drawing pattern is rough. The cause of this pattern collapse is assumed to be blurring caused by diffusion of radiated light inside photo-curable resin 3. Accordingly, if same control is performed for when a dense drawing pattern is to be formed and when a rough drawing pattern is to be formed, the following problem will occur. If a drawing condition suitable for a dense drawing pattern is set, and a rough drawing pattern is formed, the rough drawing pattern is not desirably formed due to lack of exposure. - However, with
nail forming device 2, which usesscanning reflection mirror 7 as described, above,light source 4 andoptical drawing unit 5 are controlled bycontroller 6, and photo-curable resin 3 may be partially cured. Unlike exposure with photomask,nail forming device 2 of the present exemplary embodiment may set a control condition for each section obtained by dividing a drawing area. Accordingly, even if there is a density difference in a drawing pattern, the control condition may be made different between a drawing area where a dense drawing pattern is to be formed and a drawing area where a rough drawing pattern is to be formed. That is,controller 6 may form an optimal drawing pattern by controllinglight source 4 andoptical drawing unit 5 according to the density of a drawing pattern. Formation of an optimal drawing pattern according to the density of a drawing pattern may be realized in the following manner. - The radiation time of light that is emitted by
light source 4 on a drawing area on which a drawing pattern is to be formed is controlled bycontroller 6. The radiation tune is determined for each section of the divided drawing area. - Also, the level of output of light that is emitted by
light source 4 on the drawing area on which a drawing pattern is to be formed is controlled bycontroller 6. The level of output of light is determined for each section of the drawing area. - Optimal control may be realized for each section obtained by division, by a combination of control conditions for the radiation tune of light and the level of output of light.
- Also, in the case of performing control on a per section basis as described above,
controller 6 has to perceive a drawing pattern. Thus,nail forming device 2 is desirably provided withcommunication unit 19 for obtaining a drawing pattern from outside. Ascommunication unit 19, a wired communication unit such as an USB, or a wireless communication unit such as a wireless LAN or Bluetooth (registered trademark) may be used. Additionally, in the present exemplary embodiment, a wireless LAN is used ascommunication unit 19. - Moreover, with respect to a drawing pattern, a drawing pattern that is selected in advance by using a smartphone, a personal computer or the like is transferred to
controller 6 by using a wireless LAN ascommunication unit 19. If a drawing pattern is input to nail formingdevice 2 from outside, the latest designs may be easily introduced even if designs are frequently updated. Accordingly, a drawing pattern may be selected from a large number of designs. Depending on the situation, users may link together and form a community. - <Details of Configuration of
Nail Forming Device 2> - Nail forming
device 2 desirably includespositioning unit 20 for determining the position ofnail 1 on which drawing is to be performed. The present exemplary embodiment describes a guide for restricting the amount of insertion of a finger by causing the tip ofnail 1 to come into contact with the guide, and for fixing the position ofnail 1. The method described above is not restrictive as long as the position ofnail 1 may be fixed. Providingpositioning unit 20 allows the position of nail I to be fixed, and therefore allows application of a detailed drawing. - As shown in
FIG. 4 , the surface ofnail 1 has a convex curved shape. Accordingly, the radiation distance fromreflection mirror 7 is different for edge part 1 a andcenter part 1 b ofnail 1. However,nail forming device 2 has a configuration where a semiconductor laser whose radiation light has high linearity is used aslight source 4, and where light with high linearity is radiated onnail 1 viareflection mirror 7, and thus a variation in a beam spot diameter caused by a difference in the distance from light source is small, and deterioration of drawing accuracy on a curved surface is suppressed. Accordingly, highly detailed drawing is enabled. - Furthermore, angle of incidence θ1 of light on
tangent plane 1 c of edge part 1 a ofcurved nail 1 is smaller than angle of incidence θ2 ontangent plane 1 d ofcenter part 1 b of the nail, and thus the radiation area of light is greater at edge part 1 a than atcenter part 1 b. Accordingly, the amount of received light per unit area is smaller at edge part la than atcenter part 1 b. Therefore, light output to edge part 1 a ofnail 1 is desirably made greater than light output to centerpart 1 b ofnail 1. Besides using the method for performing adjustment based on the level of intensity of output light, adjustment may be performed by making the radiation time of light on edge part 1 a longer than the radiation time of light oncenter part 1 b ofnail 1. - Additionally, adjustment of the radiation time may be controlled by adjusting the displacement rate of the angle of reflection of
reflection mirror 7. However, it is difficult to finely adjust the angle of reflection. As a method for controlling the radiation time without controlling the angle of reflection, there is light emission control for the light source. The light control is control of the number of times the light source is switched on during a period of scanning of a unit area by light. If a semiconductor laser is used, the number of times of switching on may be controlled by controlling a clock signal for performing light emission control of the semiconductor laser. If the semiconductor laser is used as the light source, the radiation time may be easily adjusted. - Moreover, a case where a semiconductor laser with high light linearity is used as
light source 4 has been described above with respect to nail formingdevice 2, but a semiconductor light emitting element or a UV lamp whose radiation light is greatly diffused may alternatively be used aslight source 4. in the case where the semiconductor light emitting element or the UV lamp is used, light linearity of radiation light may be obtained by interposing a collimator lens (not shown) betweenlight source 4 andreflection mirror 7. If light linearity of radiation light may be obtained, the same effect as when a semiconductor laser is used may be achieved. - Furthermore, instead of using
scanning reflection mirror 7 as described above as drawing means, a projection device such as a digital mirror device or a liquid crystal device may be used as scanning means. - Also, by providing
storage unit 21 tocontroller 6, and storing typical drawing patterns in advance instorage unit 21, drawing may be performed based on stored drawing patterns. Ifcontroller 6 is provided withstorage unit 21, a drawing pattern may be selected without usingcommunication unit 19, and time may be reduced by the length of the transfer time for the drawing pattern. - Furthermore, to determine a control condition with respect to the curved shape of
nail 1,nail forming device 2 further includesnail detector 22 for detecting the three-dimensional shape ofnail 1, andcontroller 6 controls at least one oflight source 4 andreflection mirror 7 according to first information detected bynail detector 22. - Feedback control is enabled by inputting information (first information) detected by
nail detector 22 tocontroller 6 as appropriate. Accordingly, correction control for the angle of reflection ofreflection mirror 7 and a radiation tinning oflight source 4 is enabled atnail forming device 2. Additionally,nail detector 22 may be a camera that uses images or may use various methods including an optical method that uses light reflection, for example. By performing feedback control by usingnail detector 22, detailed drawing may be performed even ifnail 1, which is a drawing target, moves. - Furthermore,
nail forming device 2 further includes light sourceoutput measurement unit 23 for measuring the level of output of light that is emitted bylight source 4, andcontroller 6 controls at least one oflight source 4 andreflection mirror 7 according to second information that is measured by light sourceoutput measurement unit 23. - By performing feedback control by information (second information) measured by light source
output measurement unit 23,nail forming device 2 may perform drawing with even higher accuracy. - Additionally, light source
output measurement unit 23 may be configured frombeam splitter 23 a provided on an optical path andphotodetector 23 b, for example. - <Nail Forming Method>
- A nail forming method that uses
nail forming device 2 described above will be described with reference toFIG. 5 . - First, a user coats the surface of his/her
nail 1 on which the nail art is to be applied with photo-curable resin 3, which is a nail material (resin-coating step S1). In the resin-coating step, the entire nail is simply coated, and there is no need to form a drawing pattern by photo-curable resin 3. - Next, a drawing pattern is selected, and control of the radiation position and the radiation time of light is performed by
controller 6 according to the drawing pattern and feedback information such as the three-dimensional shape nail 1 and the level of output, and the photo-curable resin is partially cured at drawingarea 3 a (curing step S2). Additionally, in the curing step,nail forming device 2 described with reference toFIG. 1 is used, andcontroller 6 controls at least one oflight source 4 andreflection mirror 7 according to the density of the drawing pattern. Control of the radiation time, the level of output of light and the like fornail forming device 2 is as described above, and description here is omitted. - Next, photo-
curable resin 3 innon-cured area 3 b, which is not ted with light and which is not cured, is removed (removal step S3). A desired drawing pattern may be formed by the series of processes of resin-coating step S1, curing step S2, and removal step S3. - Also, if resin-coating step S1, curing step S2, and removal step 53 described above are repeatedly performed, a three-dimensional drawing pattern having a laminate structure may be formed. Also, by using a gel nail with differently colored layers, a colorful drawing pattern may be formed.
- Moreover, since the curing wavelength is different depending on the type of photo-
curable resin 3, a plurality oflight sources 4 with different wavelengths are desirably provided aslight source 4. At the time of control oflight sources 4 bycontroller 6, the control condition is desirably different for each of different waveforms. - Furthermore, in the exemplary embodiment described above, an example is described according to the case in which the nail art is applied on the surface of
nail 1, but the same effects may be obtained also when the nail art is applied on an artificial nail bynail forming device 2 of the present exemplary embodiment. - Still further, in the present exemplary embodiment, an example is described according to the case in which a user applies the nail art on his/her
own nail 1 bynail forming device 2, butnail forming device 2 may be installed at a nail salon, and a nail technician may usenail forming device 2 of the present exemplary embodiment. Ifnail forming device 2 of the present exemplary embodiment is used by nail technicians, the drawing accuracy may be prevented from being varied depending on the skill of each nail technician, or the application time may be reduced. - The nail forming device of the present invention may easily form a drawing pattern on nails or artificial nails. It is particularly advantageous in the case of a user forming a drawing pattern on his/her own nails.
