The head moving mechanism 62 movably supports the print head 61 in each of the front, rear, left, and right directions within the region of the upper half portion in the housing 2.

The control device 80 is a computer including a control unit 81 configured by a CPU (Central Processing Unit) (not shown) and a storage unit 82 having a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Is.

The storage unit 82 stores various programs, various data, and the like for operating the printing device 1.
Specifically, the storage unit 82 has a program storage area 821 in which various programs such as a print program for performing a print process are stored. The control device 80 expands and executes the program stored in the program storage area 821, for example, in the work area of the RAM, so that each part of the printing device 1 is controlled in an integrated manner.

The control unit 81 includes functional units such as a shooting control unit 811, a nail information detection unit 812, a print data generation unit 813, a print control unit 814, a display control unit 815, and a print finger discrimination unit 816. The functions of each of these functional units are realized by the cooperation between the CPU of the control unit 81 and the program stored in the storage unit 82.

The photographing control unit 811 controls the photographing device 51 and the lighting device 52 of the photographing unit 50, and causes the photographing device 51 to photograph the nail image of the printing finger U arranged on the printing table 13. The image data of the nail image acquired by the photographing unit 50 is stored in the storage unit 82.

The nail information detection unit 812 detects nail information about the nail of the printing finger U based on the nail image. The nail information detection unit 812 of the present embodiment detects at least a nail region surrounded by the contour of the nail as nail information.

The print data generation unit 813 fits (enlarges / reduces, etc.) the nail design selected by the user so as to match the contour of the nail detected by the nail information detection unit 812, and generates print data.

The print control unit 814 outputs a control signal to the print unit 60 based on the generated print data, and prints according to the print data on the claws. The print head 61 and the head movement mechanism of the print unit 60 are performed. 62 etc. are controlled.

The display control unit 815 controls the display unit 40 to capture a nail image of the print finger U, an image of the contour of the nail, an image pattern of the nail design to be printed, a print preview image for design confirmation, and an instruction to the user. An image or the like is displayed on the display 24.

The print finger determination unit 816 determines the print finger U on the printing table 13 based on the detection result of the distance sensor 45. More specifically, as will be described later, the print finger discriminating unit 816 detects the non-printing finger N in the lower opening 12 based on the detection result of the distance sensor 45, and the finger other than the non-printing finger N ( The finger included in) is determined as the print finger U.

When the display 24 (touch panel 31) is a mobile terminal that can be attached to and detached from the housing 2, wireless LAN, Bluetooth (registered trademark), and Wi- It may be configured to perform wireless communication by Fi or the like. The user can operate the printing device 1 in cooperation with the mobile terminal by operating the mobile terminal to perform various inputs, settings, and the like.

Subsequently, the printing method (printing process) by the printing apparatus 1 will be described.
FIG. 4 is a table showing a combination of printing fingers U of both hands that can be printed by the printing apparatus 1, and FIG. 5 is a flowchart showing a flow of printing processing. 6A and 6B are side views showing an arrangement example of a printing finger U and a non-printing finger N, in which (a) is for four-finger printing and (b) is for thumb printing. 7A and 7B are plan views showing an arrangement example of the printing fingers U, in which (a) prints the four fingers of the left hand and the thumb of the right hand, and (b) shows the thumb of the left hand and the four thumbs of the right hand. This is for printing a finger.

In the printing apparatus 1 of the present embodiment, a plurality of printing fingers U can be set at one time to print at one time. However, unlike the other four fingers, the thumb nails face sideways when the hand is spread, so the thumb nails cannot be printed with the other four fingers of the same hand. The combination of the printing fingers U of both hands that can be printed at the same time is the thumb of one hand and the four fingers of the other hand, or the thumbs of both hands. Specifically, it is possible to print a combination of the printing fingers U of both hands as shown in FIG. 4 (including the case of using only one hand or the case of using only one hand) at one time.
Further, in the printing process of the present embodiment, it is assumed that the base paint is applied to the nail of the printing finger U in advance. This base paint is a base coat of white or a color close to it, and makes the color development of the ink stand out when the design is printed. In addition, by applying the base paint, it becomes easier to distinguish the skin color (skin color, etc.) around the nail, and it becomes easier to recognize the nail region more accurately from the nail image.

As shown in FIG. 5, when the printing process is executed, the control unit 81 first selects the nail design to be printed on the nail based on the user operation (step S1). The user selects a desired nail design by operating the touch panel 31 or the like.
Next, the control unit 81 edits the design data such as changing the position and size as necessary based on the user operation (step S2).

Next, the control unit 81 selects the print finger U to print based on the user operation (step S3). Here, which finger of which hand is to be printed is selected and set. The set combination of print fingers U is stored in the storage unit 82.
At this point, which design should be printed on which fingernail may be set, and the order of steps S1 to S3 may be changed.

Next, the control unit 81 determines the set pattern of the print finger U based on the information of the print finger U selected in step S3 (step S4). Specifically, the control unit 81 determines which set pattern of FIG. 4 corresponds to the combination of the selected printing fingers U of both hands.

Next, the control unit 81 determines whether or not the combination of the print fingers U determined in step S4 is the set pattern 8 in which the thumb of any hand and the other four fingers do not include the print finger U. (Step S5).
Then, when it is determined that the combination of the print fingers U determined in step S4 is the set pattern 8 (step S5; Yes), the process proceeds to step S19 described later.

Further, in step S5, when it is determined that the combination of the printing fingers U determined in step S4 is not the set pattern 8 (step S5; No), the control unit 81 performs a pattern set for initial printing (step S6). ), The finger set guidance corresponding to the set pattern determined in step S4 is displayed on the display 24 (step S7).
In this set guidance, a method (arrangement position, etc.) of arranging the printing fingers U arranged in the upper opening 11 (upper surface of the printing table 13) corresponding to the combination of the printing fingers U is guided. The set guidance information is stored in the storage unit 82 in advance in association with each set pattern, and the information corresponding to the set pattern determined in step S4 is read out and displayed. In the set guidance, the method of arranging the non-printing finger N arranged in the lower opening 12 may be guided.

Next, the user places the print finger U on the printing table 13 according to the set guidance displayed in step S7 (step S8), and then gives an input instruction to start printing by the touch panel 31 (step S9).

When the user inputs a print start instruction, the control unit 81 detects the print finger U (step S10).
Here, the print finger discrimination unit 816 detects the non-printing finger N in the lower opening 12 by the distance sensor 45, and discriminates a finger (a finger included in) other than the non-print finger N as a print finger U. ..

In this step S10, the print finger discrimination unit 816 determines whether the non-print finger N is a thumb or four fingers other than the thumb, based on the vertical height of the non-print finger N.
Specifically, for example, as shown in FIGS. 6A and 6B, when the non-printing fingers N detected in the lower opening 12 are thumbs, the non-printing fingers N are four fingers other than the thumb. Its height is lower than that of a finger. Therefore, the print finger discrimination unit 816 determines the non-print finger N as the thumb when the non-print finger N is smaller than the predetermined height threshold, and determines the non-print finger N as the thumb when the non-print finger N is equal to or higher than the height threshold. The print finger N is discriminated as four fingers other than the thumb. The height threshold may be set between the height of the thumb and the height of the four fingers.
Then, when the non-printing finger N is the thumb, the print finger discrimination unit 816 determines that the print finger U of the hand is four fingers (at least one) other than the thumb, and the non-print finger N determines. If there are four fingers other than the thumb, the printed finger U of that hand is determined to be the thumb.

Further, the print finger discrimination unit 816 determines whether the non-print finger N is the finger of the left or right hand based on which side of the lower opening 12 the non-print finger N is located on the left or right side. do.
Specifically, for example, as shown in FIG. 7A, when the non-printing finger N of four fingers is on the right side of the lower opening 12, the non-printing finger N is the non-printing finger N. Is determined to be the finger of the right hand HR, and the printed finger UR of the right hand HR is determined to be the thumb. Further, when the non-printing finger N of the thumb is on the left side of the lower opening 12, the printing finger discriminating unit 816 determines the non-printing finger N as the finger of the left hand HL, and determines the printing finger UL of the left hand HL. Identify as four fingers (at least one) other than the thumb.
Alternatively, as shown in FIG. 7B, when the non-printing finger N of the thumb is on the right side of the lower opening 12, the printing finger discriminating unit 816 uses the non-printing finger N as the finger of the right hand HR. The printing finger UR of the right hand HR is discriminated as four fingers (at least one) other than the thumb. Further, when the non-printing finger N of four fingers is on the left side of the lower opening 12, the printing finger discriminating unit 816 determines the non-printing finger N as the finger of the left hand HL, and determines the non-printing finger N of the left hand HL. Identify UL as the thumb.
When two left and right non-printing fingers N are detected, the right non-printing finger N may be identified as the right finger and the left non-printing finger N may be identified as the left finger.

Next, as shown in FIG. 5, the control unit 81 determines whether or not the arrangement of the finger (hand) on the printing table 13 is correct based on the information of the printing finger U detected in step S10 (). Step S11).
Specifically, the control unit 81 determines whether or not the print finger U detected in step S10 corresponds to the print finger U selected in step S3 (whether the set pattern matches), and corresponds to the print finger U. If not, it is judged that the finger arrangement is not correct.
When it is determined that the finger arrangement is incorrect (step S11; No), the control unit 81 displays an error on the display 24 to warn (notify) the user that the finger arrangement on the printing table 13 is incorrect (step S11; No). Step S12). Then, the control unit 81 shifts the process to the above-mentioned step S7, and displays the set guidance of the set pattern corresponding to the print finger U detected in the step S10 on the display 24.

When it is determined in step S11 that the arrangement of the fingers on the printing table 13 is correct (step S11; Yes), the control unit 81 uses the photographing control unit 811 to place the printing finger U on the printing table 13. The image is taken by the photographing unit 50, and the nail image is acquired (step S13).
Then, the control unit 81 detects the nail area (printing range) based on the acquired nail image by the nail information detection unit 812 (step S14). In the present embodiment, the nail portion coated with the base paint is detected as the nail region.
The nail area (printing area) may be detected as an area within the contour of the nail, not as a portion coated with the base paint. Then, which finger the nail region is located may be specified from the contour shape of the nail and its position.

Next, the control unit 81 determines whether or not the number of claw areas (printing ranges) detected in step S13 matches the number of printing fingers U selected in step S3 (step S15).
Then, when it is determined that these numbers do not match (step S15; No), the control unit 81 displays an error notifying the user of this mismatch on the display 24 (step S16), and then steps S3 described above. Move the process to and start over from the selection of the print finger U.

When it is determined that the number of claw regions detected in step S13 matches the number of print fingers U selected in step S3 (step S15; Yes), the control unit 81 prints by the print data generation unit 813. Data is generated (step S17), and printing is executed for the print finger U by the print control unit 814 (step S18).

Next, the control unit 81 determines whether or not there is another finger to print (other than the one printed in step S18) based on the user operation (step S19), and there is another finger to print. If it is determined (step S19; Yes), the process proceeds to step S1 described above.
If it is determined that there is no other finger to print (step S19; No), the control unit 81 ends the printing process.

As described above, according to the present embodiment, the print finger U is determined based on the detection result of the distance sensor 45 that detects the non-print finger N.
As a result, the printing finger U can be suitably discriminated without inviting an increase in the size of the apparatus by configuring each of the plurality of fingers to be arranged at a specific position.

Further, according to the present embodiment, the distance sensor 45 is configured to be able to detect the left and right positions and the top and bottom heights of the non-printing finger N as seen by the printing user. Then, the control unit 81 (printing finger discrimination unit 816) determines whether the non-printing finger N is located on the left or right side of the lower opening 12, and the non-printing finger N is the finger of either the left or right hand. Based on the vertical height of the non-printing finger N, it is determined whether the non-printing finger N is a finger or a finger other than the thumb, and a finger included in the determined non-printing finger N is printed. It is determined to be a finger U (finger to be printed).
Thereby, the printing finger U can be suitably identified.

Further, according to the present embodiment, the print finger U is set in advance based on the user operation, and it is determined whether or not the set print finger U and the determined print finger U correspond to each other, and it is determined that the print finger U does not correspond to the set print finger U. If so, the user is notified to that effect.
This prevents the printing finger U from being accidentally set. As a result, it is possible to suppress the occurrence of a problem that a different design is printed on the printing finger U.

Further, according to the present embodiment, the printing finger U is a finger other than the thumb of the right hand and the thumb of the left hand, or a finger other than the thumb of the left hand and the thumb of the right hand.
Even when printing with both hands at one time in this way, the set print finger U is automatically determined and its correctness is confirmed, so there is no need for the support of an operator other than the user, and multiple print fingers are required. The printing finger U can be suitably printed.
Further, by printing the thumbs having different claw orientations separately from the other four fingers of the same hand, it is possible to print all the fingers in the direction in which the ink from the print head 61 properly lands, and the printing quality is high. Can be guaranteed.

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, the case where the printing fingers of both hands are all four fingers other than the thumb is excluded (see FIG. 4), but this case may also be supported.

Further, in the present embodiment, the print head 61 is of an inkjet method, but the configuration (printing method) of the print head 61 is not limited to this, and a configuration other than the inkjet method such as a pen plotter method may be used. There may be.
