Description

The present invention relates to a nail printing device, a drawing system, a terminal device, a drawing method, and a drawing program.

Conventionally, a drawing device (nail printing device) that prints a nail design on a fingernail or the like is known (for example, Patent Document 1).
In such a drawing device, if the position of the nail to be printed cannot be correctly specified, the printing will be misaligned and a beautiful finish will not be obtained.

In particular, when printing on nails, unlike printing on paper, the color does not develop as expected even if printing is performed as it is, and yellow (Y; YELLOW) and magenta (M;) commonly used in drawing devices are used. For reasons such as the fact that white cannot be expressed with MAGENTA) or cyan (C; CYAN) ink, white ink is applied to the surface of the nail in advance before printing by the drawing apparatus.
Further, when the position or range of the nail to be printed is specified by image recognition based on the photographed image of the nail, it is difficult to distinguish the nail from the skin around it and recognize it correctly. For this reason, the nail may be recognized after applying a base material (coating agent) such as white to the surface of the nail in advance.

In this way, when white ink or various coating agents are applied to the surface of the nail, the nail (finger corresponding to the nail) moves after the position of the nail is recognized and before printing. As a result, the part where the nail design should be printed will have an unpainted part such as white, which will make the appearance worse. In this case, it is necessary to remove all the ink once and start over from the place where the ink such as white or the base is applied again, which is troublesome.
In this regard, Patent Document 1 describes that a jig for fixing a finger is provided so that the nail (finger corresponding to the nail) does not move during printing, and printing is performed on the fixed nail.

Special Table 2003-534083

However, even if the finger is fixed to the jig, it is difficult to completely fix the nail (finger) at the time of printing, and the possibility of misalignment of the nail cannot be eliminated.
Further, if it is fixed too tightly, the burden on the user becomes heavy, which is not preferable.
For this reason, there has been a demand for a method capable of beautifully finishing a nail print even if the position of the nail is displaced.

The present invention has been made in view of the above circumstances, and even if the position of the nail is displaced after the position of the nail is recognized and the planned print area is set, a beautiful nail print without an unprinted area can be obtained. It is an advantage to provide a nail printing device, a drawing system, a terminal device, a drawing method and a drawing program that can be finished.

In order to solve the above problems, the nail printing apparatus of the present invention is used.
A first photographed image obtained by photographing the nail after applying a base having a color different from both the color of the nail and the color of the finger corresponding to the nail to the nail and before printing the nail design. A print head that prints the nail design on the planned print area, which is the area where the base is applied, based on the print data generated in accordance with the planned print area.
A control unit that controls the operation of the print head,
With
When the control unit detects an unprinted area in the planned print area from a second photographed image obtained by photographing the nail after printing the nail design based on the print data by the print head. It is characterized in that the print head is controlled so as to perform correction printing for correcting the nail design printed on the nail based on the correction data generated in accordance with the unprinted area.

According to the present invention, even if the position of the nail shifts after the position of the nail is recognized and the planned print area is set, it is possible to finish a beautiful nail print without an unprinted area.

The communication unit 14 is connected to the communication control unit 311 (see FIG. 2) of the control device 30 described later, and is controlled by the communication control unit 311.

Further, printing by the nail printing device 1 is performed on the front side (front side in FIG. 1) of the housing 11 and substantially in the center of the device in the X direction (X direction in FIG. 1, left and right direction of the nail printing device 1). A finger insertion opening 15, which is an opening for inserting a finger at times, is formed.
The inside of the finger insertion opening 15 is a finger receiving portion 20 which is a space for receiving a finger such as a printing finger U1 inserted at the time of printing. Here, the printing finger U1 is a finger corresponding to the nail T to be printed by the printing unit 40.
A finger placing portion 21 on which the printing finger U1 is placed is provided in the finger receiving portion 20. The finger resting portion 21 may be configured to be movable up and down, and in this case, the height of the finger resting portion 21 can be adjusted according to the thickness of the printing finger U1 and the like.

It should be noted that, in the finger receiving portion 20, on the back side of the device in the Y direction (Y direction in FIG. 1, depth direction of the nail printing device 1, front-rear direction), a printing finger inserted in the finger receiving portion 20. A claw stand (not shown) may be provided on which the tip of the claw T of the U1 is placed and the position of the claw T is defined. It is particularly preferable to provide a claw stand because the position of the claw T in the height direction is less likely to shift.
Further, the holding portion of the printing finger U1 including the finger resting portion 21 may be a finger holding unit that can be attached to and detached from the housing 11. In this case, the housing 11 is provided with an opening or a lid for attaching / detaching the unit.

The printing finger U1 (and its claw T) can be placed at a predetermined printing appropriate position simply by inserting it inside.

Further, inside the housing 11, a printing unit 40 for printing on the nail T (the surface of the nail T) of the printing finger U1 and a photographing unit 50 for acquiring a photographed image of the printing finger U1 including the nail T are provided. Has been printed.
The photographing unit 50 (see FIG. 2) includes an imaging device 51 and a lighting device 52.
The photographing unit 50 illuminates the claw T of the printing finger U1 placed on the finger placing unit 2 by the lighting device 52. Then, the printing finger U1 is photographed by the imaging device 51 to obtain a photographed image (an image of the printing finger U1 including an image of the nail T).

In the present embodiment, the user previously applies a base (base coating agent, etc.) or white ink having a color different from that of the nail T and the finger (printing finger U1) to the nail T (the entire nail T or a portion of the nail T where printing is planned). It is designed to be applied (see FIGS. 3 (b) and 4 (a)).
The nail T and the printing finger U1 are generally skin-colored or the like, and the base is another color. In the present embodiment, the nail information detection unit 313, which will be described later, detects the planned printing area (the entire nail T or the portion of the nail T where printing is scheduled) from the captured image of the printing finger U1. Therefore, in order to make it easier to distinguish the part to be printed by the image analysis from the non-printed part of the surrounding fingers (skin) and nail T, the background is preferably a color that can be distinguished from the skin color or the like in the image analysis. For low-brightness colors (for example, black and navy blue) and highly saturated colors (for example, relatively strong colors such as red, orange, and pink), even if other colors of ink are applied from above by printing. It is difficult to erase, and the color of the nail design deteriorates, so it is not preferable as a base. Therefore, for example, a white coating agent or the like is preferably used as the base. The background color is not limited to white.

The photographing unit 50 of the present embodiment photographs the nail T to which the base or white ink has been applied in advance to acquire a photographed image.
Specifically, the photographing unit 50 photographs the nail T (the nail T coated with the base or white ink) before printing, and the first photographed image P1 (FIGS. 3 (b) and 4 (a)). See). Further, after printing by the printing unit 40, the printed nail T (nail T on which the nail design is printed on the base or white ink) is photographed and the second photographed image P2 (FIG. 4 (b), (See FIGS. 5 (a) and 5 (b)) is acquired.
The captured images (first captured image P1, second captured image P2) acquired by the photographing unit 50 may be stored in the storage unit 32 described later. Further, it may be sent to the terminal device 7 via the communication units 14, 74 (see FIG. 2).

An inkjet method in which ink is directly sprayed from the ink ejection surface onto the surface of the claw T (planned print area Ar1 or unprinted area Ar2 in the claw surface), which is the surface to be printed of the print target (claw T). It is an inkjet head.
The print head 41 is, for example, a cartridge-integrated type containing inks of each color, and can eject yellow (Y; YELLOW), magenta (M; MAGENTA), and cyan (C; CYAN) inks. .. The ink that can be ejected by the print head 41 is not limited to these. For example, black (K; BLACK) ink may be built-in, and black (K) ink may also be ejected.

The control device 30 is installed on, for example, a substrate (not shown) arranged on the lower surface side of the top surface of the housing 11.
As shown in FIG. 2, the control device 30 includes a control unit 31 composed of a processor such as a CPU (Central Processing Unit) (not shown), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like (both are shown in FIG. It is a computer including a storage unit 32 composed of (not shown).

The storage unit 32 stores various programs (not shown), various data, and the like for operating the nail printing device 1.
Specifically, the ROM 321 of the storage unit 32 stores various programs such as a printing program for performing printing processing, and when these programs are executed by the control device 30, the nail printing device 1 Each part is controlled in a centralized manner.

From a functional point of view, the control unit 31 includes a communication control unit 311, an imaging control unit 312, a claw information detection unit 313, a print control unit 314, and the like. The functions as the communication control unit 311, the photographing control unit 312, the claw information detection unit 313, the print control unit 314, etc. are realized by the cooperation between the CPU of the control unit 31 and the program stored in the ROM 321 of the storage unit 32. To.

The communication control unit 311 controls the operation of the communication unit 14. In the present embodiment, the communication with the terminal device 7 is controlled, and when the print data Dt, the correction data Dc, or the like is transmitted from the terminal device 7, it is received.
Further, when the planned print area Ar1 or the nail information is detected by the nail information detection unit 313 described later, it is transmitted to the terminal device 7 side.
Further, when the captured image is acquired by the photographing unit 50, the data of the captured image may be transmitted to the terminal device 7.

The photographing control unit 312 controls the image pickup device 51 and the lighting device 52 of the photographing unit 50 to cause the image pickup device 51 to take a picture of the printing finger U1 placed on the finger resting part 2, and includes an image of the nail T. The photographed image is acquired.
In the present embodiment, the photographing control unit 312 controls the imaging device 51 and the lighting device 52 of the photographing unit 50 to cause the photographing unit 50 to perform photographing before and after printing (first printing, nail printing), respectively. The first photographed image P1 and the second photographed image P2 are acquired.
The captured images (first captured image P1, second captured image P2) acquired by the photographing unit 50 are transmitted to the terminal device 7 via the communication units 14 and 74. The image data may be stored in the storage unit 32.

Further, the nail information detection unit 313 analyzes the photographed image obtained by photographing the nail T and the nail T coated with the base of a color different from that of the finger (printing finger U1), and prints the area where the base is applied. Detected as the planned area Ar1.
In the present embodiment, the nail information detection unit 313 detects the planned print area Ar1 from the first photographed image P1 obtained by photographing the nail T before printing, and photographs the nail T after printing. The unprinted area Ar2 in the planned print area Ar1 is detected from the second captured image P2.
As shown in FIG. 3A, the nail T is difficult to distinguish from the color of the surrounding skin such as a finger when nothing is applied. In this regard, in the present embodiment, as described above, the surface of the nail T is previously coated with a base such as white or white ink (see FIG. 3B). Therefore, the nail information detection unit 313 analyzes the brightness, brightness, hue, etc. of the first captured image captured before printing to separate the painted portion such as the base and the other portion. It can be recognized separately. Then, the nail information detection unit 313 detects the area where the base or the like is painted as the planned print area Ar1 (that is, the range to be printed).
The method for the claw information detection unit 313 to detect the planned print area Ar1 is not limited to the one illustrated here, and various methods can be used.

In this embodiment, the contour of the entire claw T (outer shape of the claw T) and the contour (range) of the planned printing area Ar1 do not always match.
For example, when it is desired to print a nail design on the entire surface of the nail T, the entire surface of the nail T is coated with a base, so that the entire surface of the nail T becomes the planned printing area Ar1. In this case, as shown in FIG. 3B, the contour of the claw T and the contour (range) of the planned print area Ar1 coincide with each other.
On the other hand, when the user desires, for example, a French nail (see FIG. 4B) in which the nail design is applied only to the tip of the nail T, the base is applied only to the tip of the nail T (FIG. 4). 4 (a)). Therefore, the nail information detection unit 313 detects only the tip portion of the nail T to which the base is applied as the planned print area Ar1. Therefore, in this case, the contour of the entire nail T and the contour (range) of the planned print area Ar1 do not match.

Further, the nail information detection unit 313 determines whether or not there is an unprinted area Ar2 in the planned print area Ar1 by analyzing the second photographed image P2 obtained by photographing the nail T after printing.
FIG. 5B shows a case where the position of the claw T is displaced between the time when the planned print area Ar1 is set based on the captured image of the first captured image P1 and the time when printing is started. It is a figure.
In FIG. 5 (b), the claw T (claw T and its printing finger U1) moves by α in the direction of the white arrow (to the right in FIG. 5 (b)), which is actually larger than the set planned print area Ar1. The claw T is shifted to the right. In this case, on the right side of the nail T, a portion of the base color or the like that remains without being printed is generated, and the nail information detection unit 313 sets the portion as the unprinted area Ar2.

Specifically, in the nail information detection unit 313, the nail design printed by the print head 41 based on the print data Dt is applied to the entire planned print area Ar1 or is not left as the base color. It is determined whether or not there is a print area Ar2.
The method by which the nail information detection unit 313 determines the presence or absence of the unprinted area Ar2 is not particularly limited.
For example, when the nail information detection unit 313 analyzes the second captured image P2 and detects an area that has not changed from the color of the background or the like even after printing, the area is determined to be the unprinted area Ar2. May be good.

Further, the claw information detection unit 313 compares the second captured image P2 with the print data Dt and looks at the difference to determine whether or not there is an unprinted area Ar2 in the planned print area Ar1. May be good. That is, when there is an unprinted area Ar2, the printed area in the second captured image P2 and the planned print range in the print data Dt do not match (printed more than the planned print range). The area of is narrower.)
Even in an area where the color does not change even after printing, if it is not the base that has been applied in advance but white ink or the like that constitutes a part of the nail design, it is not necessary to perform correction printing. In this regard, when determining the presence or absence of the unprinted area Ar2 by comparing the second captured image P2 with the print data Dt, only the portion requiring correction printing can be appropriately detected.
When the unprinted area Ar2 is detected in the planned print area Ar1 by analyzing the second captured image P2, the claw information detection unit 313 detects the position, area, and width of the unprinted area Ar2.

Further, the nail information detection unit 313 detects the nail information about the nail T of the printing finger U1 based on the image (photographed image) of the nail T of the printing finger U1 taken by the imaging device 51.
Here, the nail information includes, for example, the contour of the nail T (the shape of the nail, the XY coordinates of the horizontal position of the nail T, etc.), the inclination angle of the surface of the nail T with respect to the XY plane (the inclination angle of the nail T, the curvature of the nail). And so on. When the height of the claw T (the vertical position of the claw T, hereinafter also referred to as "the vertical position of the claw T" or simply "the position of the claw T") can be obtained from an image or the like taken by the image pickup device 51. Also includes the height of the nail T in the nail information.
Information on the planned print area Ar1 and the unprinted area Ar2 acquired by the claw information detection unit 313, and information such as the contour and curvature of the claw T are transmitted to the terminal device 7 via the communication units 14 and 74.

The print control unit 314 is a control unit that controls the X-direction moving motor 46, the Y-direction moving motor 48, the print head 41, and the like of the printing unit 40.
In the present embodiment, the print data Dt and the correction data Dc generated by the print data generation unit 813 are sent from the terminal device 7 side to the nail print device 1 side via the communication units 14 and 74. The print control unit 314 outputs a control signal to the print unit 40 based on the print data Dt and the correction data Dc, and prints on the claw T according to the print data Dt and the correction data Dc. Each part of the printing part 40 is controlled in this way.
That is, when the print data Dt is sent, the print control unit 314 causes the nail design to be printed in the planned print area Ar1 of the nail T based on the print data Dt.
Further, when the correction data Dc is sent, the print control unit 314 causes the unprinted area Ar2 of the claw T to perform correction printing based on the correction data Dc.

The print data generation unit 813 generates print data Dt so as to match the planned print area Ar1 (from the area scheduled to be printed by the print unit 40) which is the detection result by the nail information detection unit 313 of the nail printing device 1. It is a thing.
In the present embodiment, as described above, the nail information detection unit 313 detects the area coated with the base as the planned print area Ar1 from the first photographed image P1 obtained by photographing the nail T before printing. .. Then, the detected information on the planned print area Ar1 is sent from the nail printing device 1 side to the terminal device 7 side.
When the information of the planned print area Ar1 is sent, the print data generation unit 813 cuts out the nail design data (original data) D according to the planned print area Ar1 and generates the print data Dt.
Further, in the present embodiment, the claw information is detected by the claw information detection unit 313, and the detection result is sent to the terminal device 7 via the communication units 14 and 74.
As described above, the nail information is specifically the shape of the nail T (the contour shape of the nail T), the curvature of the nail T, and the like, and the print data generation unit 813 also takes into account such nail information to correct the curved surface. Etc., necessary corrections and the like are performed appropriately, and the printing unit 40 generates printing data Dt for printing in the planned printing area Ar1 from the nail design data (original data) D.

The nail design data (original data) D is made larger than the nail T, and the print data generation unit 813 includes the nail design data (original data) so as to include the design arranged near the center of the data. ) Set the print data Dt centering on the vicinity of the center of D.
It should be noted that there is no particular limitation on how and at what position the print data Dt is set. For example, from the nail design data (original data) D, a portion on which a large pattern is drawn and its surroundings may be extracted to generate print data Dt, or each nail design data (original data) D may be generated in advance. The main pattern part may be set and specified for. Further, the user may be able to set from the operation unit 71 or the like which part of the nail design data (original data) D is desired to be adopted as the nail design. If there is any setting or designation in advance, the print data generation unit 813 sets the print data Dt in a range including the set pattern portion, the range specified by the user, and the like accordingly. To do.

6 (a) to 6 (c) show an example of the nail design data (original data) D, and in the example shown in FIG. 6 (b), the center of the nail design data (original data) D. The case where the range including the part where the large fireworks pattern is drawn (the range shown by the solid line in FIGS. 6 (b) and 6 (c)) is set as the print data Dt is illustrated.
In the present embodiment, the print data generation unit 813 generates (cuts out) the print data Dt, and at the same time, the extended range data Dm larger than the print data Dt cut out from the nail design data D (in FIG. 6C). The range indicated by the broken line) is generated. The extended range data Dm is obtained by extending the range beyond the print data Dt to the periphery thereof. For example, a range extended to the outside by 2 mm around the print data Dt is set as the extended range data Dm.
The print data Dt and the extended range data Dm generated by the print data generation unit 813 are stored in the storage unit 82 (for example, the design storage area 822 in the storage unit 82) or the like in an associated state. The nail design data (original data) D may also be stored in association with the print data Dt and the extended range data Dm.

Further, in the present embodiment, when the unprinted area Ar2 is detected by the claw information detection unit 313, the claw information detection unit 313 detects the position, area, and width of the unprinted area Ar2 as described above. Then, information such as the position, area, and width of the unprinted area Ar2 is sent to the terminal device 7.
When the unprinted area Ar2 is detected by the claw information detection unit 313 and information such as the position, area, and width of the unprinted area Ar2 is sent, the print data generation unit 813 does not print from the extended range data Dm corresponding to the print data Dt. A portion corresponding to the region Ar2 is cut out to generate correction data Dc.

The print data Dt and correction data Dc generated by the print data generation unit 813 are transmitted to the nail print device 1 side via the communication units 14 and 74, and the nail print and correction data Dc based on the print data Dt are transmitted. The correction printing based on the above is performed by the print head 41 of the nail printing device 1.

FIG. 7A shows an example of correction data Dc cut out from the extended range data Dm by the print data generation unit 813, and FIG. 7B shows correction data for the unprinted area Ar2. It shows the nail T and the printing finger U1 when the correction printing based on Dc is performed.
The black shaded area in FIG. 7A is in the planned print area Ar1 due to the displacement of the claw T in the print data Dt that should be originally printed in the planned print area Ar1 of the nail T. Means the part that was not printed correctly.
In the example shown in FIG. 7A, the unprinted area Ar2 is generated on the opposite side to the black shaded portion because the black shaded portion is not printed correctly. Therefore, the print data generation unit 813 is a portion corresponding to the unprinted area Ar2 and continuous with the print data Dt (in FIG. 7A, the extended range data adjacent to the right side of the print data Dt). The portion of Dm) is cut out as correction data Dc so as to match the position, area, width, etc. of the unprinted area Ar2.
The correction data Dc generated in this way is sent to the nail printing apparatus 1, and the printing unit 40 performs correction printing for filling the unprinted area Ar2 as the second printing based on the correction data Dc.

Next, a drawing method (nail printing method), which is a drawing method of the present embodiment, will be described with reference to FIG. 8 and the like.
When performing nail printing using the nail printing device 1 of the present embodiment, the user operates the operation unit 12 or the like of the nail printing device 1 to turn on the power and start the operation.
Further, the power of the terminal device 7 is turned on, and the execution of the nail print process is selected from the operation unit 71 of the terminal device 7. This activates the nail print AP821b.
When the nail print AP821b is activated, the display control unit 812 of the terminal device 7 causes the display unit 72 to display a list of nail designs and a message instructing the user to select a desired design. Next, the user selects a nail design to be printed on the nail T by operating the touch panel or other operation unit 71.
As a result, an operation signal is sent to the control device 80, and as shown in FIG. 8, a desired nail design is selected as the nail design to be printed on the nail T (see step S1 and FIG. 6A).

Next, the display control unit 812 of the terminal device 7 applies a base (or white ink if white is contained) to the nail T to be printed on the display unit 72, and then the nail T (and its printing finger U1). ) Is placed on the finger resting portion 2 of the nail printing device 1 to display an instruction screen.
When the printing finger U1 is placed on the finger placing portion 2, the printing finger U1 including the claw T is photographed by the photographing unit 50, and the first photographed image P1 (see FIG. 3B) is acquired (see FIG. 3B). Step S2).
When the first captured image P1 is acquired, the nail information detection unit 313 performs image processing on the first captured image P1 to set the area coated with the base (or white ink) as the planned print area Ar1. Detect (step S3).
When the user wishes to print French nails or the like and applies the base material or white ink only to a part of the nail T such as the tip of the nail T, the nail information detection unit 313 uses the base material or the white ink. Only the coated portion is detected as the planned print area Ar1 (see FIG. 4A).
Information on the planned print area Ar1 (position, shape, etc. of the planned print area Ar1) detected by the claw information detection unit 313 is sent to the terminal device 7. Further, when the claw information detection unit 313 detects claw information such as the shape of the claw T and the curvature of the claw T, these information are also transmitted to the terminal device 7 side.

When the information of the planned print area Ar1 is sent, the print data generation unit 813 of the terminal device 7 fits the nail design data (original data, nail design data D) selected in step S1 to the planned print area Ar1. Then, necessary corrections and the like are performed to generate print data Dt (see step S4 and FIG. 6B). Further, the print data generation unit 813 generates extended range data Dm (see FIG. 6C), which is data in a wider range than the print data Dt, and associates the print data Dt with the extended range data Dm. The data is stored in the storage unit 82 (for example, the design storage area 822 of the storage unit 82).
The print data Dt generated by the print data generation unit 813 is transmitted to the nail print device 1. Upon receiving the print data Dt, the print control unit 314 of the nail print device 1 outputs the print data Dt to the print unit 40, and cooperates with a drawing processing program or the like to print a planned print area based on the print data Dt. The first printing process for printing the nail design on Ar1 is performed (step S5).

When printing based on the print data Dt (first printing) is completed, the printing finger U1 including the claw T is photographed again by the photographing unit 50, and the second photographed images P2 (FIGS. 5A and 5B) are taken. ) Is acquired (step S6). When the nail design is applied only to the tip of the nail T, for example, the second captured image P2 as shown in FIG. 4B is acquired.
When the second captured image P2 is acquired, the nail information detection unit 313 performs image processing on the second captured image P2 to determine whether or not there is an unprinted region Ar2 in the planned print area Ar1. (Step S7).
When there is no unprinted area Ar2 (step S7; NO, see FIGS. 5A and 4B), the drawing process ends.

On the other hand, when the unprinted area Ar2 is detected (step S7; YES, see FIG. 5B), the information of the unprinted area Ar2 (for example, the position, range, width, etc. of the unprinted area Ar2) is the terminal. It is transmitted to the device 7.
When the detection result by the claw information detection unit 313 is transmitted, the print data generation unit 813 generates the correction data Dc that matches the unprinted area Ar2 (step S8).
Specifically, the print data generation unit 813 reads out the extended range data Dm stored in association with the print data Dt, and is a portion adjacent to the print data Dt and the position of the unprinted area Ar2. Data that fits the range, width, etc. is generated as correction data Dc (see FIG. 7A).
The correction data Dc generated by the print data generation unit 813 is transmitted to the nail print device 1. Upon receiving the correction data Dc, the print control unit 314 of the nail printing device 1 outputs the correction data Dc to the printing unit 40, cooperates with a drawing processing program or the like, and based on the correction data Dc, the print head. A second printing process for performing correction printing on the unprinted area Ar2 by 41 is performed (step S9).

In this way, when there is an unprinted area Ar2, by performing correction printing based on the correction data Dc, it is possible to perform correction printing in which the unprinted area Ar2 is filled with a pattern continuous with the print data Dt. it can. Therefore, it is possible to give the nail T a beautifully finished nail design that does not give a sense of discomfort as a whole (see FIG. 7B).

As described above, according to the present embodiment, the planned print area Ar1 which is the area where the base is applied from the first photographed image P1 obtained by photographing the claw T before printing by the claw information detection unit 313. Upon detection of the print data generating unit 813 in accordance with the scheduled printing region Ar1 generates print data Dt cut out the nail design data D, the print head 41, the nail design to print schedule area Ar1 based on the print data Dt The first printing is performed.
Further, when the claw information detection unit 313 detects the unprinted area Ar2 in the planned print area Ar1 from the second photographed image P2 obtained by photographing the claw T after printing, the print data generation unit 813 detects the unprinted area Ar2. A second print is performed in which the correction data Dc suitable for Ar2 is generated, and the print head 41 performs correction printing on the unprinted area Ar2 based on the correction data Dc.
As described above, in the present embodiment, the nail T is photographed before and after printing the nail design, and if there is an unprinted area Ar2 in the first printing (first printing), it is cut out as printing data Dt. The unprinted area Ar2 can be filled with continuous data (correction data Dc) in the portion.
Therefore, even if the user's nail T or finger is not completely restrained to stop the movement, if the position of the nail T shifts after the planned print area Ar1 is set, the unprinted area Ar2 is appropriately corrected by correction. It can be buried in the nail print, and a beautifully finished nail print can be performed without burdening the user.

Further, in the present embodiment, the print data Dt generated by the print data generation unit 813 is stored in association with the nail design data D or the extended range data Dm larger than the print data Dt cut out from the nail design data D. A storage unit 82 is further provided.
As a result, the original data Nail design data D and the extended range data Dm can be associated with the print data Dt, and when the unprinted area Ar2 occurs, continuous data can be easily added to the print data Dt. It can be used to generate correction data Dc.
Therefore, even if an unprinted area Ar2 is generated, a natural nail design in which the entire pattern is connected can be printed on the nail T, and a beautifully finished nail print can be realized.

Further, when the nail information detection unit 313 analyzes the second captured image P2 and detects an area that has not changed from the color of the background (or white ink or the like), it determines that the area is an unprinted area Ar2. In this case, the unprinted area Ar2 can be easily detected only by detecting the area where the color of the background (or white ink or the like) remains.

Further, when the claw information detection unit 313 determines whether or not there is an unprinted area Ar2 in the planned print area Ar1 by comparing the second captured image P2 with the print data Dt, it is originally determined. When it is intended to leave the white-painted portion as a part of the design, the white-painted portion as a part of the design can be distinguished from the unprinted area Ar2 and the desired printing can be appropriately realized.

Further, in the present embodiment, the nail information detection unit 313 detects the position, area, and width of the unprinted area Ar2 when the unprinted area Ar2 is detected in the planned print area Ar1 from the second captured image P2. To do.
As a result, the print data generation unit 813 can appropriately generate the correction data Dc that matches the range and shape of the unprinted area Ar2.

Further, in the present embodiment, when the unprinted area Ar2 is detected by the nail information detection unit 313, the print data generation unit 813 does not print from the nail design data D or the extended range data Dm corresponding to the print data Dt. A portion corresponding to the region Ar2 is cut out to generate correction data Dc.
As a result, correction data Dc can be generated using data continuous with the print data Dt, and even if an unprinted area Ar2 is generated, a nail design with a natural finish in which the entire pattern is connected. Can be printed on the nail T.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to such embodiments and can be variously modified without departing from the gist thereof.

For example, in the present embodiment, when the print data generation unit 813 generates the extended range data Dm and generates the correction data Dc, it is decided to cut out a portion corresponding to the unprinted area Ar2 from the extended range data Dm. However, it is not essential to generate extended range data Dm.
For example, the original data Nail design data D is stored in association with the print data Dt, and when the correction data Dc is generated, a portion matching the unprinted area Ar2 is cut out from the nail design data D. May be.
In this case, it is not necessary to have the extended range data Dm in addition to the nail design data D, and the present embodiment does not have to secure a process for generating the extended range data Dm and a memory for storing the extended range data Dm. The same effect as the above can be realized.

Further, in the present embodiment, the case where the claw T is displaced in the lateral direction (the direction of the white arrow in FIG. 5B) is illustrated, but the direction in which the claw T is displaced is not limited to this.
In any direction of vertical and horizontal deviation, the unprinted area Ar2 generated by the displacement of the claw T can be filled by correction printing by the same measures as in the present embodiment.
If the direction in which the claw T shifts is limited to a certain direction such as the lateral direction, the extended range data Dm may be data in which the range is expanded only in the direction in which the shift may occur. Good.

Further, in the present embodiment, the case where the presence / absence of the unprinted area Ar2 is determined after the printing of the entire planned print area Ar1 is completed has been illustrated, but the timing for determining the presence / absence of the unprinted area Ar2 is the entire planned print area Ar1. Not limited to after printing is completed.
After some printing based on the print data Dt is performed, it is frequently checked whether or not the unprinted area Ar2 is generated in the printing, and when the unprinted area Ar2 is found, the correction printing is performed each time. May be good.
For example, when printing is performed on the entire planned print area Ar1 by a plurality of scans such as four reciprocating scans, the presence or absence of the unprinted area Ar2 may be checked each time the print is reciprocated.
In addition, when printing is completed by scanning a plurality of times, there is a possibility that a deviation may occur due to correction in the middle. In such a case, after printing of the entire planned print area Ar1 is completed. It is preferable to determine the presence or absence of the unprinted area Ar2.

Further, for example, the entire planned print area Ar1 may be printed by scanning once for each round trip.
In this case, the claw T is photographed by the photographing unit 50 at the time of switching between the outward route and the return route, and the second photographed image P2 obtained by photographing the claw T is scheduled to be printed at the end of printing on the outward route. It may be determined whether or not there is an unprinted area Ar2 in the area Ar1. Then, when the unprinted area Ar2 is detected, correction data P2 that can fill the unprinted area Ar2 may be generated, and correction printing may be performed based on the correction data P2 on the return route.
