Description

The present invention relates to a printing device, a control method for a printing device, and a control program.

Conventionally, there is known a printing device (nail print device) that prints nail designs on fingernails, etc. In most printing devices of this type, fingers are set into the device one by one and printed, but in recent years, devices that can print on the nails of multiple fingers at the same time have been developed.
For example, the printing device described in Patent Document 1 uses a finger holder on which each of a number of fingers is placed in a specific position, making it possible to specify the finger to be printed on and print a design corresponding to each finger.

Special Publication No. 2003-534083

However, if a configuration is adopted in which each of a plurality of fingers is placed at a specific position, this leads to an increase in the size of the device.
The present invention has been made in consideration of the above circumstances, and has an object to suitably identify the finger that is the printing target.

The printing device of the present invention comprises:
A printing means for printing on the fingernail;
A detection means for detecting fingers other than the finger to be printed;
A discrimination means for discriminating the finger to be printed based on a detection result of the detection means;
a printing table having a finger placement surface on which the finger to be printed is placed,
the detection means is arranged in a space below the finger placement surface, and is configured to be able to detect the left-right position and the up-down height of the other finger placed in the space as seen from a user who performs printing,
The discrimination means is
determining whether the other finger is a finger of a left or right hand based on whether the other finger is located on the left or right side of the space;
determining whether the other finger is a thumb or a finger other than the thumb based on the vertical height of the other finger;
A finger other than the identified other fingers is identified as the finger to be printed.
It is characterized by:

The present invention makes it possible to effectively identify the finger to be printed on.

An embodiment of a printing apparatus, a control method and a control program thereof according to the present invention will be described with reference to FIGS.
In addition, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.
In addition, in the following embodiment, a nail printing device will be described as an example in which the printing device prints on the printing target of a fingernail, however, the printing target of the printing device in this invention is not limited to fingernails, and the printing target may be, for example, the nails of toes.

FIG. 1 is a perspective view showing the appearance of a printing device 1 according to this embodiment.
In the following embodiments, up/down, left/right, and front/rear (front and back) refer to directions as seen by a user (operator) facing the printing device 1, and are the directions shown in FIG.

As shown in FIG. 1, the printing device 1 has a housing 2 formed in a substantially oval cylindrical shape.
A power switch 22, an LED display unit 23, a display 24, etc. are arranged on the top surface of the housing 2.
The power switch 22 is an operation button for turning the power of the printing device 1 on and off.
The LED display unit 23 displays the status of the printing device 1 by emitting light in a color corresponding to the status of the printing device 1 .
The display 24 is, for example, a liquid crystal display (LCD), an organic electroluminescence display (OLED), or other flat display, and displays various information. The display 24 is also integrated with a so-called touch panel 31, and is capable of receiving touch operations by the user.
The display 24 may be a portable terminal such as a smartphone or tablet that is detachable from the housing 2.

An opening/closing plate 25 is provided on the front surface of the housing 2. The opening/closing plate 25 is connected to the housing 2 via a hinge (not shown) provided on the lower end of the front surface of the housing 2 so as to be able to rise and fall.
The opening/closing plate 25 opens and closes the upper opening 11 and the lower opening 12 that are open on the front surface of the housing 2 .

FIG. 2 is a schematic cross-sectional side view of the printing device 1. As shown in FIG.
As shown in this figure, the upper opening 11 and the lower opening 12 open in the lower half of the front surface of the housing 2, and are arranged side by side one above the other with a flat printing table 13 separating them.
Of these, the upper opening 11 is a space into which the finger having the nail to be printed (print finger U: see FIG. 6) is inserted. That is, in the upper opening 11 (the upper surface of the printing table 13), the thumb is placed when printing the thumb (hereinafter, sometimes referred to as "thumb printing"), and the four fingers are placed when printing at least one of the four fingers other than the thumb (hereinafter, sometimes referred to as "four-finger printing"). The upper opening 11 is formed with a width that allows the fingers of both hands to be inserted without difficulty.

The fingers other than the printing finger U of the same hand (non-printing fingers N: see FIG. 6 ) are placed in the lower opening 12. That is, in the lower opening 12 (the space below the printing table 13), the four fingers other than the thumb of the hand are placed in the case of thumb printing, and the thumb of the hand is placed in the case of four-finger printing. The lower opening 12 is formed with a width and height that allow the non-printing fingers N of both hands to be inserted without difficulty.
Further, the lower opening 12 is provided with a distance sensor 45 for detecting a non-printing finger N placed within the lower opening 12 .

The distance sensor 45 is an example of a detection means according to the present invention. The distance sensor 45 is disposed at the rear of the lower opening 12, and is capable of detecting the presence (presence) and position (front/back, left/right, top/bottom position) of a non-printing finger N in the lower opening 12, and is an optical sensor such as a photointerrupter in this embodiment. However, the type of the sensor of the distance sensor 45 is not particularly limited as long as it can detect the presence (presence) and position of an object in the lower opening 12 and does not affect the human body.
Furthermore, a plurality of distance sensors 45 (at least two vertical rows and two horizontal columns, totaling four sensors) are arranged vertically and horizontally (illustrated as an integrated unit in Figs. 2, 6, and 7). This makes it possible to detect the horizontal position and vertical height of the non-printing finger N in the lower opening 12, and the printing finger U is identified based on the detection results. A specific identification method will be described later.

Furthermore, within the housing 2, a photographing unit 50 and a print head 61 are disposed in a portion above the upper opening 11. This upper portion communicates with the upper opening 11.
Of these, the photographing unit 50 is disposed on the top surface (lower surface of the upper plate) of the housing 2 above the nail of the printing finger U that is placed on the upper surface of the printing table 13, and photographs the nail. Specifically, the photographing unit 50 includes a photographing device 51 and a lighting device 52 (see FIG. 3 ), and photographs the nail of the printing finger U that is placed on the upper surface of the printing table 13 with the photographing device 51 while illuminating the nail with the lighting device 52, thereby obtaining a nail image (an image of the finger including the nail) that is an image of the nail of the printing finger U.
The photographing device 51 is a small camera equipped with a solid-state photographing element such as a CCD (Charge Coupled Device) type or a CMOS (Complementary Metal Oxide Semiconductor) type having 2 million or more pixels, a lens, etc. The lighting device 52 is an illumination lamp such as a white LED, and is provided on both the left and right sides of the photographing device 51.

The print head 61 is an inkjet head that uses an inkjet system to print by spraying minute droplets of ink from an ink ejection section on the underside of the print head onto the print surface of the print target (nail). The print head 61 is capable of ejecting, for example, yellow (Y; YELLOW), magenta (M; MAGENTA), and cyan (C; CYAN) ink.

FIG. 3 is a block diagram showing the control configuration of the printing device 1.
As shown in this figure, the printing device 1 includes, in addition to the distance sensor 45 and image capturing unit 50 described above, an operation unit 30, a display unit 40, a printing unit 60, a control device 80, and the like.

The operation unit 30 includes the power switch 22 and the touch panel 31 described above, and outputs a signal corresponding to the position of the touch panel 31 when it is operated to the control device 80 .
The display unit 40 is equipped with the above-mentioned LED display unit 23 and display 24, and based on a display signal input from the control device 80, lights up the LED display unit 23 in various colors and displays various information on the display 24.

The printing unit 60 includes the above-mentioned print head 61 and a head moving mechanism 62 that supports the print head 61 .
The head moving mechanism 62 supports the print head 61 within the upper half area of the housing 2 so that the print head 61 can move in all directions, front to back, left to right.

The control device 80 is a computer that includes a control unit 81 that is configured with a CPU (Central Processing Unit) (not shown), and a storage unit 82 that includes a ROM (Read Only Memory), a RAM (Random Access Memory), etc.

The storage unit 82 stores various programs and various data for operating the printing device 1 .
Specifically, the storage unit 82 has a program storage area 821 in which various programs such as a printing program for performing printing processing are stored. The control device 80 loads the programs stored in the program storage area 821, for example, into a working area of a RAM, and executes them, thereby controlling each part of the printing device 1 in an integrated manner.

The control unit 81 includes functional units such as a photography 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 these functional units are realized by cooperation between the CPU of the control unit 81 and a program stored in the memory 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 a nail image of the printing finger U placed on the printing table 13. The image data of the nail image acquired by the photographing unit 50 is stored in the memory unit 82.

The nail information detection unit 812 detects nail information about the nail of the print finger U based on the nail image. In this embodiment, the nail information detection unit 812 detects at least the nail area surrounded by the outline of the nail as the nail information.

The print data generation unit 813 generates print data by fitting (enlarging or reducing, etc.) the nail design selected by the user to the nail contour detected by the nail information detection unit 812.

The print control unit 814 outputs a control signal to the print unit 60 based on the generated print data, and controls the print head 61 and head movement mechanism 62 of the print unit 60 so as to print on the nail according to the print data.

The display control unit 815 controls the display unit 40 to display on the display 24 a nail image of the print finger U, an image of the nail outline, an image pattern of the nail design to be printed, a print preview image for confirming the design, an image of instructions for the user, etc.

The printing finger discrimination unit 816 discriminates the printing finger U on the printing table 13 based on the detection result of the distance sensor 45. More specifically, as described below, the printing finger discrimination unit 816 detects the non-printing finger N in the lower opening 12 based on the detection result of the distance sensor 45, and discriminates fingers other than the non-printing finger N (fingers included in the non-printing finger N) as printing fingers U.

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

Next, a printing method (printing process) performed by the printing device 1 will be described.
Fig. 4 is a table showing combinations of printing fingers U of both hands that can be printed by the printing device 1, and Fig. 5 is a flowchart showing the flow of the printing process. Fig. 6 is a side view showing an example of the arrangement of printing fingers U and non-printing fingers N, (a) for four-finger printing, and (b) for thumb printing. Fig. 7 is a plan view showing an example of the arrangement of printing fingers U, (a) for printing four fingers of the left hand and the thumb of the right hand, and (b) for printing the thumb of the left hand and four fingers of the right hand.

In the printing device 1 of this embodiment, multiple printing fingers U can be set at one time and printed simultaneously. However, since the thumb nail faces to the side when the hand is spread apart from the other four fingers, the thumb nail cannot be printed together with the other four fingers of the same hand. The combination of printing fingers U of both hands that can be printed simultaneously 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 combinations of printing fingers U of both hands (including the case of only one hand or only one finger) as shown in FIG. 4 at the same time.
In addition, in the printing process of this embodiment, it is assumed that a primer is applied in advance to the nail of the printing finger U. This primer is a base coat of white or a color close to white, and makes the color of the ink stand out when the design is printed. In addition, applying the primer also makes it easier to distinguish the color of the skin around the nail (flesh color, etc.), making it easier to more accurately recognize the nail area from the nail image.

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

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

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

Next, the control unit 81 determines whether the combination of the printing fingers U determined in step S4 is set pattern 8 that does not include the printing finger U in the thumb and other four fingers of either hand (step S5).
If it is determined that the combination of the printing fingers U determined in step S4 is set pattern 8 (step S5; Yes), the process proceeds to step S19, which will be described later.

Furthermore, in step S5, if it is determined that the combination of printing fingers U determined in step S4 is not set pattern 8 (step S5; No), the control unit 81 sets a pattern for initial printing (step S6), and causes the display 24 to display finger set guidance corresponding to the set pattern determined in step S4 (step S7).
This set guidance provides guidance on how to arrange (position, etc.) the printing fingers U to be placed in the upper opening 11 (upper surface of the printing table 13) corresponding to the combination of printing fingers U. Information on the set guidance is stored in advance in the storage unit 82 in association with each set pattern, and information corresponding to the set pattern determined in step S4 is read out and displayed. The set guidance may also provide guidance on how to arrange the non-printing fingers N to be placed in the lower opening 12.

Next, the user places the printing finger U on the printing table 13 according to the setting guidance displayed in step S7 (step S8), and then inputs an instruction to start printing via the touch panel 31 (step S9).

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

In step S10, the printing finger discrimination unit 816 discriminates whether the non-printing finger N is the thumb or one of the four fingers other than the thumb, based on the vertical height of the non-printing finger N.
6A and 6B, for example, when the non-printed finger N detected in the lower opening 12 is a thumb, its height is lower than when the non-printed finger N is one of the four fingers other than the thumb. Therefore, when the non-printed finger N is smaller than a predetermined height threshold, the printed finger discrimination unit 816 discriminates the non-printed finger N as a thumb, and when the height is equal to or greater than the height threshold, the printed finger discrimination unit 816 discriminates the non-printed finger N as one of the 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.
If the non-printed finger N is the thumb, the printed finger discrimination unit 816 discriminates the printed finger U of the hand as (at least one of) the four fingers other than the thumb, and if the non-printed finger N is the four fingers other than the thumb, it discriminates the printed finger U of the hand as the thumb.

Furthermore, the printing finger discrimination unit 816 discriminates whether the non-printing finger N belongs to the left or right hand based on whether the non-printing finger N is located on the left or right side of the lower opening 12 .
7A, when a non-printed finger N of the four fingers is on the right side of the lower opening 12, the printed finger discrimination unit 816 discriminates the non-printed finger N as a finger of the right hand HR and discriminates the printed finger UR of the right hand HR as the thumb. Also, when a non-printed finger N of the thumb is on the left side of the lower opening 12, the printed finger discrimination unit 816 discriminates the non-printed finger N as a finger of the left hand HL and discriminates the printed finger UL of the left hand HL as (at least one of) the four fingers other than the thumb.
7B, when a non-printed finger N of the thumb is on the right side of the lower opening 12, the printed finger discrimination unit 816 discriminates the non-printed finger N as a finger of the right hand HR, and discriminates the printed finger UR of the right hand HR as (at least one of) the four fingers other than the thumb. Also, when a non-printed finger N of the four fingers is on the left side of the lower opening 12, the printed finger discrimination unit 816 discriminates the non-printed finger N as a finger of the left hand HL, and discriminates the printed finger UL of the left hand HL as the thumb.
When two non-printed fingers N, one on the left and one on the right, are detected, the right non-printed finger N may be determined as a finger of the right hand, and the left non-printed finger N as a finger of the left hand.

Next, as shown in FIG. 5, the control unit 81 determines whether or not the placement 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 the printing finger U detected in step S10 corresponds to the printing finger U selected in step S3 (whether the set pattern is correct), and if they do not correspond, determines that the finger placement is incorrect.
If it is determined that the finger placement is incorrect (step S11; No), the control unit 81 displays an error on the display 24 to warn (notify) the user that the finger placement on the printing table 13 is incorrect (step S12). Then, the control unit 81 shifts the process to the above-mentioned step S7, and causes the display 24 to display the set guidance of the set pattern corresponding to the printing finger U detected in step S10.

Furthermore, if it is determined in step S11 that the finger placement on the printing table 13 is correct (step S11; Yes), the control unit 81 causes the photographing control unit 811 to photograph the printing finger U placed on the printing table 13 using the photographing unit 50, and obtains a nail image (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 this embodiment, the nail area where the base paint is applied is detected as the nail area.
The nail region (print region) may be detected as the region within the outline of the nail, not as the portion coated with the base paint. Then, it may be possible to identify which finger the nail region belongs to based on the outline shape and position of the nail.

Next, the control unit 81 determines whether or not the number of nail regions (printing ranges) detected in step S13 matches the number of printing fingers U selected in step S3 (step S15).
If it is determined that these numbers do not match (step S15; No), the control unit 81 displays an error on the display 24 to inform the user of the mismatch (step S16), and then transitions to the above-mentioned step S3, where the process starts over from selecting the printing finger U.

If it is determined that the number of nail regions detected in step S13 matches the number of printing fingers U selected in step S3 (step S15; Yes), the control unit 81 generates printing data using the printing data generation unit 813 (step S17) and executes printing on the printing fingers U using the printing control unit 814 (step S18).

Next, the control unit 81 determines whether there are other fingers to be printed (other than the one printed in step S18) based on the user operation (step S19), and if it determines that there are other fingers to be printed (step S19; Yes), it transitions to the processing of step S1 described above.
Moreover, if it is determined that there are no other fingers to be printed (step S19; No), the control unit 81 ends the printing process.

As described above, according to this embodiment, the printing finger U is identified based on the detection result of the distance sensor 45 that detects the non-printing finger N.
This makes it possible to suitably identify the printing finger U without increasing the size of the device by, for example, configuring each of a plurality of fingers to be placed in a specific position.

According to the present embodiment, the distance sensor 45 is configured to detect the left-right position and the top-bottom height of the non-printed finger N as viewed from the user who performs printing. The control unit 81 (printed finger discrimination unit 816) then discriminates whether the non-printed finger N is a finger of the left or right hand based on whether the non-printed finger N is located on the left or right side of the lower opening 12, discriminates whether the non-printed finger N is a thumb or a finger other than the thumb based on the top-bottom height of the non-printed finger N, and discriminates the finger other than the discriminated non-printed finger N as a printed finger U (a finger to be printed).
This allows the printing finger U to be appropriately identified.

Furthermore, according to this embodiment, the printing finger U is set in advance based on a user operation, and it is determined whether or not this set printing finger U corresponds to the identified printing finger U. If it is determined that they do not correspond, the user is notified to that effect.
This makes it possible to prevent the printing finger U from being set by mistake, and thus to suppress the occurrence of a problem such as a different design being printed on the printing finger U.

Furthermore, according to this embodiment, the printing fingers U are the fingers other than the thumb of the right hand and the thumb of the left hand, or the fingers other than the thumb of the left hand and the thumb of the right hand.
Even when printing on both hands at the same time in this manner, the set printing finger U is automatically identified and its correctness is confirmed, so that a plurality of printing fingers U can be suitably printed without the need for support from an operator other than the user.
Furthermore, by printing the thumb, which has a different nail orientation, separately from the other four fingers of the same hand, it is possible to print all fingers in a direction that ensures the ink from the print head 61 lands properly, thereby ensuring print quality.

Although the above describes an embodiment of the present invention, it goes without saying that the present invention is not limited to such an embodiment and various modifications are possible without departing from the spirit of the present invention.

For example, in this embodiment, cases where the printed fingers on both hands are all four fingers other than the thumb are excluded (see Figure 4), but it is also possible to accommodate this case.

In addition, in this embodiment, the print head 61 is of an inkjet type, but the configuration (printing type) of the print head 61 is not limited to this, and may be of a type other than the inkjet type, such as a pen plotter type.

Although several embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and its equivalents.
