The glitter bottle pen 41c is a glitter sprinkling part that sprinkles glitter on the surface of the nail T that is a drawing target surface.
Fig.5 (a) is a schematic diagram which shows the cross section of a glitter bottle pen.
The glitter bottle pen 41c has a shaft portion 413 having substantially the same thickness and shape as the pen shaft portion 411 of the drawing pen 41a and the glue pen 41b, and a distal end side (lower side in FIG. 5A) of the shaft portion 413. And an opening 414 provided. The distal end side of the shaft portion 413 is formed in a funnel shape that narrows toward the opening 414.
Glitter is accommodated in the shaft portion 413. The glitter bottle pen 41c has a function of sprinkling glitter on a glue pattern drawn with glue.

Glitter is a flake-like material prepared by performing aluminum vapor deposition on a polyester film and cutting a metallic film having a color layer thereon into a uniform shape. Glitter includes lame, hologram, pearl, and the like.
In addition, the size of the glitter is approximately 100 μm or more in order to ensure the glitter. Therefore, even if the tip diameter of the glitter bottle pen 41c is about 500 μm, the glitter is used in the state where the tip of the bottle (glitter bottle pen 41c) faces downward, and the electrostatic force and van der Waals from the inside of the bottle to the tip of the bottle. Since they are agglomerated by force, they become clogged. That is, even if the front end of the glitter bottle pen 41c is opened, the glitter does not spill out. Further, there is almost no change in the amount of glitter fall due to a change in the remaining amount (internal capacity).

  A vibration generating device 415 is provided at the end of the glitter bottle pen 41c opposite to the opening 414. The vibration generator 415 includes a vibration motor 415a, a shaft 415b, and a weight 415c. The vibration motor 415a is fixed to the inner wall of the glitter bottle pen 41c by a bracket 415d. The vibration generator 415 drops the glitter accommodated in the glitter bottle pen 41c by vibration.

FIG. 5B is an enlarged view of the vicinity of the vibration motor.
The vibration motor 415a is a small cylindrical vibration motor, and ON / OFF is controlled according to image information by a drawing control unit 815 (see FIG. 6). The vibration motor 415a and the weight 415c are connected by a shaft 415b. Due to the rotation of the vibration motor 415a, the weight 415c rotates, and vibration is generated due to an unstable movement that breaks the balance. By this vibration, the entire glitter bottle pen 41c vibrates, and the glitter inside the glitter bottle pen 41c can be dropped from the glitter bottle pen 41c onto the surface of the nail T. By turning this vibration (vibration motor 415a) ON / OFF, it is possible to control the start / stop of the glitter sprinkling operation from the glitter bottle pen 41c. In this embodiment, the vibration motor 415a is used as a device that applies vibration to the glitter bottle pen 41c. However, any type of actuator that generates vibrations such as a linear vibration actuator or a giant magnetostrictive element actuator can be used. It is.

The shaft portion 413 of the glitter bottle pen 41c is provided with an external contact (not shown) for supplying power from the outside. When the glitter bottle pen 41c is mounted on the pen holder 42, the pen holder 42 It is electrically connected to a movable contact (not shown) provided. The movable contact is constituted by a spring or the like, for example.
The drawing control unit 815 controls power supply to the movable contact of the pen holder 42, thereby controlling ON / OFF of rotation of the vibration motor 415a, that is, ON / OFF of vibration in the vibration generator 415.

The glitter is dropped from the opening 414 by vibrating the glitter bottle pen 41c by the vibration generating device 415. When no vibration is generated by the vibration generator 415, the glitter bottle pen 41c does not spill even if the glitter bottle pen 41c is moving in the X direction, the Y direction, or the vertical direction.
Note that the vibration width of the vibration generating device 415 may be changeable according to the material and size of the glitter. For example, a control line for controlling the rotation speed of the vibration motor 415a is provided on the shaft portion 413 of the glitter bottle pen 41c. When the glitter bottle pen 41c is attached to the pen holder 42, vibration is transmitted through the control line. The motor 415a and the drawing control unit 815 are connected, and the drawing control unit 815 can adjust the vibration width of the vibration generator 415.

  Examples of commercially available glitter bottle pens include body jewelry self kit A (Uphills Co., Ltd.) and GRACIA (registered trademark) Glitter Alpha GL-016 (Gracia Japan Co., Ltd.). These commercially available products are those in which the pen is manually shaken to sprinkle the glitter. In the case of commercially available products, when the bottle tip is not shaken, the glitter does not spill out due to the action of electrostatic force or van der Waals force at the tip of the bottle even if the pen tip is directed downward.

As shown in FIG. 4B, the pen holder 42 includes a cylindrical member 421 that opens up and down and the pen 41 is inserted therein, and a lower side (lower side in FIG. 4B) of the cylindrical member 421.

Based on the nail information, the height of the nail T at the abutting position where the tip of the pen 41 (the pen tip 412) abuts on the nail T is recognized, and the pen up / down motor 426 is detected according to the height. Determine the number of steps. The pen up / down motor 426 is driven with the number of steps determined in this manner, and the pen 41 is pushed down by the leaf spring 429 so that the tip portion (pen tip 412) of the pen 41 is brought into close contact with the surface of the nail T, so Apply pressure.

When drawing, when the height of the nail T changes with drawing, the writing pressure of the pen 41 is adjusted by increasing / decreasing the number of steps of the pen up / down motor 426 each time, and the writing pressure is substantially constant. Draw while adjusting. Here, the adjustment of the writing pressure by increasing / decreasing the number of steps of the pen up / down motor 426 is performed every time the height of the nail T changes by a predetermined amount (for example, 0.5 mm). When the change is less than the predetermined amount, the pen pressure is not adjusted. At this time, the pen spring 41 is automatically moved up and down as the leaf spring 429 is bent and deformed (elastically deformed) according to the shape of the nail T. The pen pressure can be kept in contact with the nail T and at the same time the writing pressure can be kept at an appropriate value.
Further, the spring constant of the leaf spring 429 is not so large, and this spring constant is set to such a value that the pawl T does not feel pain when the pressing force (external force) by the leaf spring 429 is applied to the pawl T. Has been. When drawing, the leaf spring 429 is appropriately bent to absorb the impact caused by the vertical movement of the pen 41, and the pen tip 412 is maintained in a state where a substantially constant appropriate pressure is applied. The pen 41 can move up and down following the height of the nail T, and a desired nail design can be clearly drawn on the surface of the nail T to be drawn.

The operation of the lifting mechanism of the drawing pen 41a and the glue pen 41b has been described above, but the mechanism of the vertical movement is the same for the glitter bottle pen 41c that does not contact the surface of the nail T.
When the glitter is not sprinkled, the leaf spring 429 does not apply an external force to the locking projection 424, and the tip (opening 414) of the glitter bottle pen 41c is from the surface of the nail T which is the drawing target surface. It is separated and held at a height that does not contact the surface (hereinafter referred to as “first position”).
In contrast, when the glitter is sprinkled, the pen up / down motor 426 is rotated by a predetermined number of steps, and the locking projection 424 is pushed down by the leaf spring 429. Thereby, the tip part (opening part 414) of the glitter bottle pen 41c is held at a height at which the distance from the surface of the nail T is a predetermined distance (hereinafter referred to as "second position").
The predetermined number of steps when driving the pen up / down motor 426 is appropriately set according to the height of the nail T of the printing finger U1 inserted into the finger receiving unit 31 or the like.
Specifically, based on the nail information acquired in advance, the tip of the glitter bottle pen 41c (opening 414) recognizes the height at which it is a predetermined distance from the surface of the nail T, and according to the height. The number of steps of the pen up / down motor 426 is determined.
In the present embodiment, the “second position” is lower than the “first position”, that is, the distance between the opening 414 of the glitter bottle pen 41c and the surface of the nail T at the “second position” is “ Although the distance between the opening 414 of the glitter bottle pen 41c and the surface of the nail T at the “first position” is shorter, the “second position” is “the first position” as long as it is suitable as the height at which the glitter is sprinkled. May be the same height as the “position”.

A nail information storage area 822 for storing the nail T outline, the inclination angle of the nail T, and the nail design storage area 823 for storing nail design image data (image information) drawn on the nail T are provided. ing.

  When viewed functionally, the control unit 81 includes an imaging control unit 811, a nail information detection unit 812, a drawing data generation unit 813, a display control unit 814, a drawing control unit 815, a fan control unit 816, and the like. The functions of the imaging control unit 811, nail information detection unit 812, drawing data generation unit 813, display control unit 814, drawing control unit 815, fan control unit 816, etc. are stored in the CPU of the control unit 81 and the ROM of the storage unit 82. Realized by working with a stored program.

The imaging control unit 811 controls the imaging device 51 and the illumination device 52 of the imaging unit 50, and the image of the finger including the image of the nail T of the printing finger U <b> 1 inserted into the finger receiving unit 31 by the imaging device 51 (hereinafter “ "Nail image").
In the present embodiment, the imaging device 51 is moved by the drawing control unit 815 that controls the head moving unit 49, and the imaging control unit 811 has two different positions and angles (for example, directly above the nail T and obliquely above the nail T). Etc.) to obtain at least two nail images.
The image data of the nail image acquired by the imaging unit 50 is stored in the nail image storage area 821 of the storage unit 82.

The nail information detection unit 812 detects nail information about the nail T of the printing finger U1 based on the image of the nail T of the printing finger U1 inserted into the finger receiving unit 31 photographed by the imaging device 51. .
Here, the nail information is, for example, the contour of the nail T (nail shape, horizontal position of the nail T), the height of the nail T (vertical position of the nail T), and the inclination of the surface of the nail T with respect to the XY plane. It is an angle (tilt angle of the nail T, nail curvature).
The nail information detection unit 812 detects nail information using a plurality of nail images photographed from different positions and angles (for example, directly above the nail T and obliquely above the nail T), so that the nail T is detected. The curvature and the like can be accurately detected.

The drawing data generation unit 813 generates drawing data to be applied to the nail T of the printing finger U1 by the drawing head 43 based on the nail information detected by the nail information detection unit 812 (fitting).
Specifically, the drawing data generation unit 813 performs alignment processing by enlarging, reducing, cutting out, etc., nail design image data based on the shape of the nail T detected by the nail information detection unit 812, and the like. Generate data for rendering.
In addition, the drawing data generation unit 813 matches the nail design image data with the shape of the nail T according to the nail information detected by the nail information detection unit 812, and appropriately performs curved surface correction or the like.
Thereby, drawing data of a nail design drawn by the drawing pen 41a, the glue pen 41b, the glitter bottle pen 41c, and the inkjet drawing unit 71 is generated.

  The display control unit 814 controls the display unit 26 to display various display screens on the display unit 26. In the present embodiment, the display control unit 814 displays, for example, a nail design selection screen, a thumbnail image for design confirmation, a nail image obtained by photographing the printing finger U1, various instruction screens, an operation screen, and the like on the display unit 26. It is supposed to be displayed.

  The drawing control unit 815 outputs a control signal to the drawing unit 40 based on the drawing data generated by the drawing data generation unit 813 and performs drawing according to the drawing data on the nail T. The control unit controls the X-direction movement motor 46, the Y-direction movement motor 48, the pen up / down motor 426, the vibration motor 415a, the inkjet drawing unit 71, and the like.

  The drawing control unit 815 moves the glue pen 41b by the pen up / down motor 426 corresponding to the pen holder 42 to which the head moving unit 49 and the glue pen 41b are attached based on the drawing data (image information), and the glue pen 41b moves the nail T. A glue pattern is drawn on the surface, and the glitter bottle pen 41c is moved by a pen up / down motor 426 corresponding to the pen holder 42 to which the head moving unit 49 and the glitter bottle pen 41c are attached based on drawing data (image information). Glitter is sprinkled on the glue pattern by the glitter bottle pen 41c.

When drawing is performed with the drawing pen 41a or the glue pen 41b, the drawing control unit 815 controls the pen up / down motor 426 during non-drawing to maintain the state in which the locking protrusion 424 is not pushed down by the leaf spring 429. Sometimes, the pen up / down motor 426 is operated to push down the locking projection 424 by the leaf spring 429 so that the tip (pen tip 412) of the pen 41 (drawing pen 41a, glue pen 41b) comes into contact with the surface of the nail T. The operation of the pen up / down motor 426 is controlled.
Note that the drawing control unit 815 appropriately increases / decreases the number of steps of the pen up / down motor 426 at a place where the height of the nail T cannot be dealt with simply by bending deformation (elastic deformation) of the leaf spring 429. It is preferable to adjust the writing pressure of the pen 41a and the glue pen 41b so that the writing pressure becomes substantially constant.

When the glitter bottle pen 41 c is moved above the nail T when the glitter is sprinkled on the glue pattern formed on the nail T, the drawing control unit 815 operates the pen up / down motor 426 to be locked by the leaf spring 429. The protrusion 424 is pushed down, and the glitter bottle pen 41c is lowered to a position (second position) where the tip (opening 414) of the glitter bottle pen 41c is a predetermined distance from the surface of the nail T.
In other words, the glitter bottle pen 41c is in a position where the glitter bottle pen 41c does not contact the surface of the nail T when the glitter is sprinkled (during drawing) or not.

The fan control unit 816 operates the dryer 91 and the exhaust fan 92 provided in the finger fixing unit 30 to dry and ventilate the finger receiving unit 31.
The fan control unit 816 operates the dryer 91 and the exhaust fan 92 for a certain period of time, for example, at the timing when the glittering operation on the claws T is completed.

Next, the operation and drawing method of the nail print apparatus 1 in the present embodiment will be described with reference to FIG.
The glitter drawing of the present invention can be performed either after drawing on the nail T with the ink jet drawing unit 71 or the drawing pen 41a, or without drawing with the ink jet drawing unit 71 or the drawing pen 41a. Here, a case where drawing is not performed by the ink jet drawing unit 71 or the drawing pen 41a will be described as an example.

When drawing with the nail printing apparatus 1, the user first turns on the power switch to activate the control apparatus 80.
The display control unit 814 causes the display unit 26 to display a design selection screen. The user operates an operation button or the like of the operation unit 25 to select a desired nail design from a plurality of nail designs displayed on the design selection screen. Thereby, a selection instruction signal is output from the operation unit 25, and a nail design to be drawn on the nail T is selected (step S1).

  Next, the control unit 81 causes the display unit 26 to display an instruction screen that prompts the user to insert the printing finger U1 into the finger receiving unit 31 (step S2). In accordance with this instruction, the user inserts the printing finger U1 into the finger receiving unit 31, inserts the non-printing finger U2 into the finger retracting unit 32, fixes the printing finger U1, and then operates the drawing start button.

  When an instruction is input from the drawing start button, before the drawing operation is started, the drawing control unit 815 first controls the head moving unit 49 so that the photographing unit 50 (the imaging device 51 and the illumination device 52) is placed in the drawing area ( That is, it is moved to the area where the nail T is arranged (step S3). Next, the imaging control unit 811 controls the imaging unit 50 to cause the imaging device 51 to image the printing finger U1 while the illumination device 52 illuminates the printing finger U1. Specifically, the imaging control unit 811 moves the position of the imaging unit 50 by the drawing control unit 815 that controls the head moving unit 49, and the image of the nail T of the printing finger U1 inserted into the finger receiving unit 31 ( At least two nail images) are acquired. Then, the nail information detection unit 812 detects nail information such as the outline (nail shape) of the nail T and the inclination angle (nail curvature) of the nail T based on the nail image (step S4).

When the nail information detection unit 812 detects the contour (nail shape) of the nail T and the inclination angle (nail curvature) of the nail T, the drawing data generation unit 813 uses the nail information to generate image data of the nail design. The fitting process to the nail T is performed.
The drawing data generation unit 813 performs curved surface correction on the image data of the nail design based on the nail information. Thereby, drawing data is generated (step S5).

  Next, the drawing control unit 815 selects the glue pen 41b and operates the head moving unit 49 to move the glue pen 41b to the drawing area (step S6). Then, the drawing control unit 815 controls the operation of the pen up / down motor 426 corresponding to the pen holder 42 to which the glue pen 41b is mounted, and pushes down the glue pen 41b to a position where the glue pen 41b comes into contact with the nail T. Then, the head moving unit 49 is controlled to draw a glue pattern on the surface of the nail T while the glue pen 41b is in contact with the surface of the nail T (step S7). When the glue pen 41b contacts the surface of the nail T, the glue is applied on the nail T, and a glue pattern is formed.

Next, the drawing control unit 815 controls the head moving unit 49 to move the photographing unit 50 to the drawing area (step S8). The photographing control unit 811 controls the photographing unit 50 to photograph the printing finger U1 with the imaging device 51 while illuminating the printing finger U1 with the illumination device 52, and obtains an image (nail image) of the nail T. Then, the nail information detection unit 812 confirms the position of the glue pattern formed on the nail T based on the nail image (step S9). Specifically, the nail information detection unit 812 compares the position (actual position) of the glue pattern recognized from the nail image with the drawing position (ideal position) of the glue included in the drawing data, Make sure that they match.
Since the glue is transparent, when photographing the glue pattern, by using the specular reflection on the boundary surface of the glue, by detecting the area where the glue is applied and the area where the glue is not applied, Recognize the position of the glue pattern.
Here, the image of the nail T may be displayed on the display unit 26, and the user may check the position of the glue pattern by looking at the image displayed on the display unit 26. For example, when the position of the glue pattern is confirmed, the operation unit 25 (OK button or the like) is operated to proceed to the next step.

  Next, the drawing control unit 815 selects the glitter bottle pen 41c, operates the head moving unit 49, and moves the glitter bottle pen 41c to the drawing area (step S10). Then, the drawing control unit 815 controls the operation of the pen up / down motor 426 corresponding to the pen holder 42 to which the glitter bottle pen 41c is mounted, and the tip end portion (opening portion 414) of the glitter bottle pen 41c is the surface of the nail T. To the position (second position) that is a predetermined distance from the head, and based on the drawing data (image information), the head moving unit 49 and the vibration motor 415a are controlled to vibrate the glitter bottle pen 41c, and the glue pattern Sprinkle glitter on top (step S11). While the glitter bottle pen 41c moves in a non-contact manner on the glue pattern, ON / OFF of the vibration motor 415a provided on the glitter bottle pen 41c is controlled, and the glitter falls on the design formed by the glue, A glitter design is formed.

  After dropping the glitter on the glue pattern, the drawing control unit 815 operates the head moving unit 49 to move the drawing head 43 to the home area 60 (step S12). The glitter falling on the glue is fixed on the nail T as the glue hardens with time, and the glitter design is completed on the nail T.

After the drawing head 43 moves to the home area 60, the fan control unit 816 controls the dryer 91 to blow air on the claws T and drives the exhaust fan 92 to be removed from the claws T. Glitter is collected (step S13). The function required of the dryer 91 at this time is not to dry the glue, but to blow away the glitter that has fallen onto unnecessary portions. That is, the dryer 91 only blows air by rotation of the fan while the heater in the dryer 91 is OFF. Unwanted glitter is removed from the nail T by the air blow from the dryer 91.
The fan controller 816 operates the dryer 91 and the exhaust fan 92 for a certain period of time, and then stops the dryer 91 and the exhaust fan 92 (step S14).
Thus, the drawing process ends.

When drawing is performed on a plurality of fingernails T, after the drawing process for one fingernail T is completed, the finger of the drawn nail T is removed from the finger receiving unit 31 and then drawn. The finger of the power nail T is inserted into the finger receiving unit 31 as the printing finger U1, and the above processing is repeated.
In the drawing process, after removing unnecessary glitter from the surface of the nail T, a top coat may be applied with the drawing pen 41a.

As described above, the nail printing apparatus 1 according to the present embodiment includes the glue pen 41b that contacts the surface of the nail T and applies the glue to the nail T, the glitter bottle pen 41c that sprinkles the glitter on the surface of the nail T, and the glue pen. 41b and the glitter bottle pen 41c are moved by the head moving unit 49 and the pen up / down motor 426, and the head pen 49b is moved by the head moving unit 49 and the pen up / down motor 426 based on the image information. A drawing control unit 815 that draws a glue pattern on the surface, moves the glitter bottle pen 41c by the head moving unit 49 and the pen up / down motor 426 based on the image information, and sprinkles the glitter pattern on the glue pattern by the glitter bottle pen 41c. And.
According to the present embodiment, by applying the glue and the glitter sprinkling, which are conventionally performed manually, a complicated design with high reproducibility can be easily obtained, and the position where the glue is applied is aimed at. Therefore, the occurrence of unnecessary glitter can be suppressed compared to the case of manual work.
Further, since the glitter contained in the glitter bottle pen 41c is dropped by the vibration by the vibration generating device 415, the glitter can be accurately sprinkled aiming at the glue pattern.
Also, since the dryer 91 blows off the extra glitter other than the glitter adhered on the glue pattern on the surface of the nail T, it is possible to remove the glitter that has fallen outside the position based on the image information. It can be beautifully finished.

In the above processing, only the air blowing function for removing unnecessary glitter is used as the dryer 91, but it is also possible to promote the drying of the glue by operating the heater and blowing hot air on the nail T. is there.
Moreover, although this embodiment demonstrated the case where only one kind of glitter was used, if a plurality of kinds of glitter bottle pens 41c are attached to the nail printing apparatus 1, a more decorative design is formed on the nail T. It becomes possible to do.
Moreover, since the decoration by the glitter can be carried out even after the design is drawn on the nail by the ink jet method, it becomes possible to obtain a nail design having a high decorating property.

  Further, since the glue pen 41b and the glitter bottle pen 41c can be replaced with a pen holder 42 common to the drawing pen 41a, there is no need to provide a pen holder dedicated to the glue pen 41b and a pen holder dedicated to the glitter bottle pen 41c, thereby saving space. Can be achieved.

  Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, in the above embodiment, the glitter bottle pen 41c includes the vibration generating device 415. However, the vibration generating device that vibrates the glitter bottle pen 41c is provided on the drawing head 43 side of the nail printing apparatus 1. It is good.
When the drawing pen 41a is a direct liquid pen, the vibration of the vibration generating device 415 of the glitter bottle pen 41c attached to the same drawing head 43 as the drawing pen 41a is used for stirring the ink. It may be used.

  In the above embodiment, the drawing head 43 including the drawing pen 41a, the glue pen 41b, the glitter bottle pen 41c, and the inkjet drawing unit 71 is moved by the head moving unit 49. You may provide the moving mechanism which moves the part 71 separately.

In the above embodiment, the drawing head 43 is provided with three pen holders 42 and can hold the three pens 41 at the same time. However, the number of pen holders 42 provided in the drawing head 43 is as follows. It is not limited to this, You may be comprised so that much more pens 41 can be hold | maintained. It is also possible to hold the drawing pen 41a for the necessary colors.
Alternatively, the drawing head 43 may be provided with only one pen holder 42 and each pen 41 may be held while being appropriately replaced. In this case, the drawing head 43 can be further downsized.
The pen 41 to be held by the pen holder 42 may be manually replaced by the user as appropriate, or a standby space for waiting the pen 41 in the home area 60 or the like is provided, and the necessary pen 41 is placed by a pen replacement mechanism (not shown). It may be automatically acquired from the waiting space and replaced with the pen holder 42.

Moreover, although the case where the imaging device 51 and the illumination device 52 are mounted on the drawing head 43 is illustrated in the present embodiment, the position where the imaging device 51 and the illumination device 52 are provided is not limited thereto.
For example, the imaging device 51 and the illumination device 52 may be fixedly disposed on the ceiling portion of the nail print device 1 or the like. In this case, in order to photograph nail images for detecting the shape and curvature of the nail T as nail information from two or more different positions and angles, the two or more imaging devices 51 are shifted in position. It is preferable to provide it.

  In this embodiment, the case where the curvature of the nail T is detected as the nail information and the drawing data is generated based on this is taken as an example. However, the detection of the curvature of the nail T is essential for the present invention. It is not a component. For example, if it is sufficient to know the approximate position of the nail T for drawing, such as when drawing a one-point pattern in the middle of the nail T, the shape and curvature of the nail T are accurately recognized. There is no need to do this, and drawing can be performed without detecting the nail shape or the like.

Further, in the above embodiment, the nail print apparatus 1 that performs drawing sequentially by inserting fingers one by one into the apparatus is taken as an example, but without inserting or removing each finger continuously with respect to a plurality of fingers. The present invention can also be applied to an apparatus that can perform drawing.
For example, by extending the operating range of the pen 41 and increasing the drawing range, it is possible to continuously draw on the nails T of each finger while the pen 41 is simultaneously inserted into the plurality of printing fingers U1.

Although the embodiment of the present invention has been described above, the scope of the present invention is not limited to the above-described embodiment, but includes the scope of the invention described in the claims and the equivalent scope thereof.
