An embodiment of a printing device, a printing control method, and a program including a control device according to the present invention will be described with reference to FIGS. 1 to 6.
Note that, although various technically preferable limitations for carrying out the present invention are attached to the embodiments described below, the scope of the present invention is not limited to the following embodiments and illustrated examples.

[Printing Device Configuration]
Fig. 1 is a perspective view showing the external configuration of the main parts of a printing device (nail print device) including a control device in this embodiment. In the following embodiment, up/down, left/right, front/rear refer to the directions shown in Fig. 1. Also, the X direction, Y direction, and Z direction refer to the directions shown in Fig. 1. Figs. 2(a) and 2(b) are diagrams showing the internal configuration of the main parts of the printing device.

As shown in FIG. 1, the printing apparatus 1 of this embodiment has a housing 2 formed in a substantially box shape. The casing 2 is divided into upper and lower parts from approximately the center in the vertical direction, and the upper part is a lid part 2a that can be rotated upward (see the arrow shown in FIG. 1) via a hinge part (not shown) or the like. There is. By opening the lid part 2a, it becomes possible to access the placing part 3, ink cartridge 41 (print head), etc., which will be described later, provided inside the housing.
An opening 21 is formed on the front side (front side in the Y direction in FIG. 2) of the casing 2 of the printing device 1 and approximately in the center of the device in the left-right direction (X direction in FIG. 2). The opening 21 is a finger insertion opening into which a finger U (see FIGS. 2(a) and 2(b)) corresponding to the nail T to be printed is inserted into the device, and the opening 21 is a finger insertion opening that allows the finger U to be inserted and removed. It has a width and height of .
In this embodiment, inside the housing 2 and inside the opening 21, there is provided a mounting section 3 on which a nail T serving as a print target and a finger U corresponding to the nail T are placed.

2(a) and 2(b), the lower surface of the placement portion 3 is a finger receiving portion 31 that receives the pad of a finger U inserted from the opening 21. The finger receiving portion 31 may be provided with a cushion member made of a flexible material such as resin.
A window 32 is formed on the top surface of the back side (rear side of the device) of the placement portion 3, which exposes the nail T of the finger U when the finger U is inserted through the opening 21 and held by the finger receiving portion 31.
In this embodiment, a frame-shaped portion 33 is provided on the front side of the placement unit 3 (the front side in the Y direction in FIG. 1 ) so as to surround the upper part of the finger U. The upper side of the finger U placed on the placement unit 3 is configured to abut against the top surface of this frame-shaped portion 33. This allows the top surface of the frame-shaped portion 33 to function as a finger rest that regulates the upward position of the finger U, preventing the finger U from rising too far upward and allowing the finger U to be positioned in the height direction.

The height, width, and length in the depth direction of the placement portion 3 may be such that the finger U can be placed stably, and the specific height and width may be set as appropriate.
Note that at least a portion of the placing section 3 (for example, the finger receiving section 31 for receiving the finger U) may be configured to be movable in the vertical direction.
The finger U inserted from the opening 21 is placed on the finger receiving part 31 of the placing part 3, and the upper surface of the finger U is defined by the top surface of the frame-shaped part 33, so that the nail T can be The ink cartridge 41 (print head) is held at an appropriate position suitable for printing.

In addition, in this embodiment, in addition to the nail T, printing can also be performed on a printing target other than the nail T.
In this embodiment, as printing objects other than the nail T, for example, a nail tip Nt (see FIG. 3) and a sticker S (see FIG. 4) are assumed.
The mounting section 3 of this embodiment is provided with a detachable auxiliary tool 34 that is attached to the main body of the mounting section 3 when printing on the nail tips Nt or stickers S to position the printing objects in a predetermined position.

The auxiliary tool 34 is prepared according to each printing object other than the nail T. Specifically, the auxiliary tool 34a shown in FIG. 3 is prepared corresponding to the nail tip Nt (see FIG. 3), and the auxiliary tool 34a shown in FIG. An auxiliary tool 34b shown in FIG. 4 is prepared corresponding to S (see FIG. 4).
When printing on the nail T, the mounting section 3 is set to only the main body (the state shown in FIGS. 2(a) and 2(b)), and when printing on the nail tip Nt, the mounting section 3 is The auxiliary tool 34a is attached (the state shown in FIG. 3), and when printing on the sticker S, the auxiliary tool 34b is attached to the mounting section 3 (the state shown in FIG. 4). As a result, the position of at least the center portion in the width direction in the height direction (Z direction in FIGS. 1 to 4) is kept constant in all cases of the nail T, the nail tip Nt, and the seal S, and the position of the ink cartridge 41 ( The distance to the ink ejection surface 411) of the ink cartridge 41 is approximately constant.

In other words, the nail tip Nt is intended to be used as an artificial nail by being attached to the surface of the nail T, and is a member curved like a nail, and like the nail T, has a height at the center in the width direction. is the highest. Therefore, as shown in FIG. 3, the nail tip Nt auxiliary tool 34a is arranged so that the nail tip Nt is almost flush with the height at which the widthwise center of the nail T is located when the nail T is the object to be printed. The dimensions are such that the highest part of the
Further, the sticker S is a flat sheet-like member that is not curved, and is, for example, a tattoo sticker or the like that is assumed to be used by pasting it on the skin of the back of the hand or the like. For this reason, as shown in FIG. 4, the auxiliary tool 34b for the sticker S is such that the entire surface to be printed on the sticker S is at the height where the widthwise center of the nail T is located when the nail T is the object to be printed. The dimensions are such that they are arranged almost flush with each other.

The auxiliary tools 34a and 34b are attached to the upper side of the receiver 3 so as to cover the window 32 of the receiver 3, for example.
When attaching the auxiliary tools 34a, 34b to the mounting section 3, open the lid 2a of the housing 2 to expose the upper surface of the mounting section 3, and attach the auxiliary tools 34a, 34b to the mounting section 3. It is locked to the window portion 32 or the like.
Note that the specific method of attaching the auxiliary tools 34a, 34b is not particularly limited. For example, the placing part 3 and the auxiliary tools 34a, 34b are provided with uneven parts (not shown) that fit into each other, and by fitting these together, the auxiliary tools 34a, 34b are fitted into the placing part 3 and locked and fixed. You can.

Here, the nail chip Nt, which is an object to be printed other than the nail T in this embodiment, is a nail-like chip made of, for example, synthetic resin.
Further, the seal S is a flat medium that is cut into a rectangular shape of a predetermined size (for example, about 3 cm x 3 cm) that can be placed on the auxiliary tool 34b. The type of sticker S is not particularly limited as long as it is made of various paper qualities suitable for printing. Note that the flat medium (sticker S) placed on the auxiliary tool 34b does not need to be paper, and may be, for example, a plate or film made of synthetic resin or the like. Note that the nail tips Nt and stickers S set on the auxiliary tools 34a and 34b may be dedicated ones that are bundled with the printing device 1, for example, or they may be appropriately prepared by the user.

In this embodiment, both the nail tip Nt and the sticker S have an ink-receiving layer on the surface (the surface to be printed), and the landed ink can be fixed on the surface. Although white nail tips Nt and stickers S are used, they are not limited thereto. For example, it may be pale pink or beige. In addition, for printing objects whose surface (printing object surface) is white etc. and has an ink-receiving layer formed thereon, as in the case of printing on nail T, base printing is performed before design printing. There is no need to do this.

An operation unit 22 is provided on the top surface (top plate) of the housing 2 .
The operation unit 22 is used by the user to input various information.
The operation unit 22 is composed of operation buttons for performing various inputs, such as a power switch button for turning the power of the printing device 1 on/off, a stop switch button for stopping operation, and a print start button for instructing the start of printing.
When the operation unit 22 is operated, an operation signal corresponding to the operation is output to the control unit 11 of the control device 10, and the control unit 11 performs control according to the operation signal to operate each part of the printing device 1.

Further, a display section 23 is arranged on the upper surface of the housing 2.
The display unit 23 includes, for example, a liquid crystal display (LCD), an organic electroluminescent display (organic ELD), or another display (flat display). The display unit 23 causes the display to display various images and information based on display signals input from the control unit 11, which will be described later.
The display of the display unit 23 of this embodiment may be integrally configured with a touch panel, and in this case, the touch panel also functions as the operation unit 22 that accepts touch operations by the user and performs various inputs.

Further, in this embodiment, the control unit 11, which will be described later, determines the printing target set on the placement unit 3, detects the type of the ink cartridge 41 (print head), and detects the type of the detected ink cartridge 41 (print head). The display unit 23 functions as a notification unit that notifies the result of this determination.
For example, a display screen (not shown) on the display unit may display information such as ``It has been confirmed that a nail is placed in the placement area'' or ``The usable ink cartridge currently set in the device is for nail chips.'' or ``The ink cartridge does not correspond to the printing target placed on the tray'' or ``Please replace the ink cartridge with one for nail printing'' to alert the user. evoke
Note that the notification unit is not limited to the display unit 23, and may include, for example, an audio output unit such as a speaker, and may notify the user by audio output.

As shown in FIGS. 2(a), 2(b), etc., a printing mechanism 4, a photographing unit 5, and the like are housed within the housing 2.

The printing mechanism 4 includes a holder 42 that houses an ink cartridge 41 (print head), and an X-direction movement motor 45 and a Y-direction movement motor 47 (see FIG. 5) that serve as movement means for moving the ink cartridge 41 (holder 42 that holds the ink cartridge 41). The ink cartridge 41 (print head) is a printing means that prints on a printing object based on print data.
In this embodiment, the ink cartridge 41 (print head) is a cartridge-integrated print head that incorporates an ink storage section (not shown) and is equipped with an inkjet-type ink ejection mechanism (not shown) that ejects the ink in the ink storage section as fine droplets and prints on the surface to be printed.

The surface of the ink cartridge 41 (print head) that faces the surface to be printed (in this embodiment, the surface of the object to be printed, such as a nail T) is integrally formed with an ink ejection surface (nozzle surface) 411. The ink ejection surface 411 has rows of ejection openings (nozzle openings, ink ejection openings, not shown) of a nozzle array consisting of a plurality of nozzles that eject ink of each color.
The ink cartridge 41 (print head) ejects a predetermined amount of ink from the nozzle openings as required by the control unit 11, which functions as a print control unit, controlling the ink ejection mechanism, thereby performing printing.
The ink cartridge 41 (print head) is not limited to the configuration exemplified here. For example, it may have a separate ink storage section, and when used for printing, the ink storage section configured as a separate entity and an ink ejection mechanism may be connected. Furthermore, there are no particular limitations on the specific configuration for printing, such as the configuration for the ink cartridge 41 (print head) to eject ink.

In this embodiment, three types of ink cartridges 41 (a first cartridge 41a, a second cartridge 41b, and a third cartridge 41c, hereinafter simply referred to as ink cartridges) are used as ink cartridges 41 (print heads) used for printing on a printing target. 41 includes all of these).
For example, the first cartridge 41a has an ink reservoir containing ink suitable for printing on the nail T of a living person as a printing object. Further, the second cartridge 41b and the third cartridge 41c have their ink reservoirs containing ink suitable for printing on printing objects other than the nail T, which is a living body. Among these, the second cartridge 41b is used for printing nail tips Nt, and the third cartridge 41c is used for printing stickers S.
Note that the ink cartridge 41 (print head) may be of two types, one for printing nails T and one for printing other than nails T (for example, nail tips Nt and stickers S in this embodiment). Further, the ink cartridges 41 (print heads) for printing on materials other than the nail T (for example, the nail tip Nt and the sticker S in this embodiment) may be further divided into three or more types depending on the material of the printing target, etc. .

These ink cartridges 41 (first cartridge 41a to third cartridge 41c) have ink storage sections corresponding to color inks of cyan (C; CYAN), magenta (M; MAGENTA), and yellow (Y; YELLOW), and are ink cartridges 41 (print heads) for design printing that print designs (nail designs) in color. Note that the inks that can be printed by the ink cartridges 41 are not limited to those listed here. They may contain inks of other colors and be capable of being ejected.
Furthermore, the first cartridge 41a for printing on the nail T is not limited to the ink cartridge 41 (print head) for design printing that stores colored inks as described above, but may be, for example, an ink cartridge 41 (print head) for base printing that forms a base of white or the like (white or a color close to white, such as pink or blue) on the nail T before design printing. The ink cartridge for base printing has an ink storage section therein that stores base ink.

The ink stored in the first cartridge 41a, the ink stored in the second cartridge 41b, and the ink stored in the third cartridge 41c have different components, and the ink does not print on the nail T, which is a living body. (In other words, the ink stored in the second head 41b and the third cartridge 41c) is focused on color development, spreadability, etc., and may contain components that cannot necessarily be said to have no effect on the human body. There is. Further, even if the colors specified as CMY print data are the same, the color development may differ depending on the ink when actually printed. Note that, for this reason, it is preferable that a different conversion table or the like for converting RGB data into CMY data for printing is prepared for each printing target.
For this reason, when printing, it is preferable to print using an ink cartridge 41 (print head) having ink suitable for each printing object.

For example, type information such as the type of ink stored in the ink cartridge 41 (print head) installed in the holder 42 that is suitable for what kind of printing target is stored, for example, in a reading unit (not shown) provided in the holder 42. It is readable. Note that the method of reading the type information of the ink cartridge 41 is not particularly limited. For example, a reading board or the like is provided in the holder 42, and the type information of the ink cartridge 41 is also included in the corresponding position on the ink cartridge 41 side. It may be configured such that the chip or the like is attached in a readable state and the type information is read when the ink cartridge 41 is attached to the holder 42.

Also, convex portions or notches may be provided at different positions for each type of ink cartridge 41 (type of ink stored therein), and switches or the like may be provided on the holder 42 side so that different switches are pressed by the convex portions or the like of the ink cartridge 41 (print head), thereby making it possible to read the type of ink cartridge 41 attached to the holder 42. Furthermore, various code information may be affixed to the side or the like of the ink cartridge 41, and a sensor or the like may be provided at a position on the holder 42 side where the code information can be read, so that the type information can be obtained by reading the code information with the sensor. There are no particular limitations on the method for reading the type of ink cartridge 41 (type of ink stored therein), and any method may be used.
The type information read from the holder 42 or the like is acquired by the control unit 11, which will be described later.
The type of ink cartridge 41 (type of ink stored therein) is not limited to being automatically read by the device when it is attached to the holder 42. For example, the user may manually input the type of ink cartridge 41 attached to the holder 42 from the operation unit 22 or the like. In this case, the input information is acquired by the control unit 11 as type information.

In this embodiment, the ink cartridge 41 (print head) is movable in the left-right direction (X direction) and the front-back direction (Y direction) of the apparatus, and the X-direction movement motor 45 moves the ink cartridge 41 in the X direction. The Y-direction movement motor 47 constitutes a Y-direction movement mechanism 470 (see FIG. 2A) that moves the ink cartridge 41 in the Y direction. ). The X-direction movement motor 45 and the Y-direction movement motor 47 are, for example, stepping motors, and their operations are controlled by a control section 11 that functions as a print control section, which will be described later.

The photographing unit 5 includes a camera 51 and a light source 52 .
The camera 51 photographs the periphery of the mounting section 3 including the window 32, thereby photographing the printing objects (i.e., the nails T, the nail tips Nt, and the stickers S in this embodiment) placed on the mounting section 3, and acquires the images. The images acquired by the camera 51 are sent to the control section 11.
The light source 52 is, for example, an illumination lamp such as a white LED.

When a nail T is placed on the placement unit 3 as a printing object, the camera 51 of the photographing unit 5 photographs the nail T and the finger U including the nail T to obtain a nail image (not shown). In this embodiment, the control unit 11 described later detects the outline of the nail (nail outline) that defines the nail area, which is the printing area, from the nail image obtained by the camera 51.
Furthermore, even when the printing object placed on the placement section 3 is not a living body such as a nail T (for example, a nail tip Nt, a sticker S, etc.), the image of the printing object photographed by the camera 51 is sent to the control section 11, where the image is analyzed and its contour shape, etc. are detected.

FIG. 5 is a block diagram of main parts showing a general control configuration of a printing device and a terminal device that cooperates with the printing device.
As shown in FIG. 5, the printing device 1 includes the above-described printing mechanism 4 and the like, as well as a communication section 25, a control device 10, and the like.

The communication unit 25 is a communication means for communicating with an external device. Note that in this embodiment, the "external device" is, for example, the terminal device 7 described later.
Communication between the printing device 1 and the terminal device 7 and the like is performed using, for example, a wireless LAN. Note that communication between the printing device 1 and the terminal device 7, etc. is not limited to this, and may be performed by any method. For example, it may use a network line such as the Internet, or it may perform wireless communication based on a short-range wireless communication standard such as Bluetooth (registered trademark) or Wi-Fi. Furthermore, this communication is not limited to the wireless connection method, and may be configured to allow transmission and reception of various data between the two parties through a wired connection. The communication unit 25 includes an antenna chip, etc. that corresponds to the communication methods and communication standards of various external devices with which it is assumed to communicate.

The control device 10 installed in the printing device 1 includes a control unit 11 having a processor such as a CPU (Central Processing Unit) (not shown), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. (both not shown). ).
The ROM of the storage unit 12 stores various programs, various data, etc. for operating the printing apparatus 1.
The control unit 11 develops various programs stored in a ROM or the like in a RAM work area and executes them, thereby controlling the operations of each unit of the printing apparatus 1 in an integrated manner.
That is, the control unit 11 realizes various functions for the printing apparatus 1 to perform print control processing, etc., in cooperation with a program (for example, a print control processing program, etc.).

In this embodiment, the control unit 11 mainly includes a display control unit that controls the operation of the display unit 23, a print control unit that controls the operation of each part of the printing mechanism 4, a photographing control unit that controls the operation of each part of the photographing unit 5, and a communication unit. It functions as a communication control means etc. that controls the operation of 25.

The control unit 11 serving as display control means generates display data to be displayed on the display of the display unit 23 and outputs it to the display unit 23. For example, the control unit 11 can display image data for displaying nail images etc. acquired by the photographing unit 5, display data for displaying designs (nail designs) etc. on the display unit 23, various message screens, guidance screens, etc. Display data and the like for displaying an error display screen and the like on the display of the display unit 23 are generated.

In particular, in this embodiment, when the control unit 11 acts as a correspondence determination unit and determines whether or not the printing target object and the ink cartridge 41 (print head) correspond to each other, this determination result is communicated to the user etc. The display unit 23 functions as a notification unit that provides notification.
For this reason, the results of determining what kind of printing target is placed on the placement unit 3 (that is, which one of the nail T, nail tip Nt, and sticker S is placed in the present embodiment), The type information of the ink cartridge 41 (print head) installed in the holder 42 is displayed on the display screen of the display unit 23, and the information on the type of ink cartridge 41 (print head) installed in the holder 42 is displayed, and the information on whether or not the object to be printed and the ink cartridge 41 (print head) correspond to each other. Display information such as "No". If the object to be printed and the ink cartridge 41 (print head) do not correspond, a message or the like is displayed on the display screen urging the user to replace or switch to the ink cartridge 41 (print head) that corresponds to the object to be printed. The control unit 11 controls the display unit 23 to display the information.

A control section 11 serving as a print control means controls the operation of the printing mechanism 4. Specifically, the control unit 11 controls the ink ejection mechanism of the ink cartridge 41 (print head) based on the print data, ejects ink as appropriate, and prints on the printing target. Further, the control unit 11 serving as a print control means appropriately operates the X-direction movement motor 45 and the Y-direction movement motor 47 to move the ink cartridge 41 (print head) in the XY directions as appropriate.

The control unit 11 as a photography control unit controls the operation of the camera 51 and the light source 52 of the photography unit 5, causes the light source 52 to illuminate the object to be printed, such as the nail T, and its surroundings, and causes the camera 51 to capture the nail image, etc. Get the image.

The control unit 11 as a communication control means controls the communication unit 25 to communicate with the communication unit 75 of the terminal device 7 and to receive, for example, original image data of a design (nail design) from the terminal device 7 .
In this embodiment, the printing device 1 operates by receiving various instructions, such as an instruction to start printing, from the terminal device 7, and the control unit 11 of the printing device 1 receives these instructions via the communication unit 25. When an instruction is received from the terminal device 7 or the like, the control unit 11 causes each unit of the device to operate in accordance with the instruction.
In addition, when a design (nail design) is selected on an external device such as the terminal device 7, the control unit 11 controls the communication unit 25 to receive data of the selected design, etc. from the external device such as the terminal device 7.

Furthermore, the control unit 11 of the present embodiment acquires an image of the printing target (that is, the nail T, nail tip Nt, and sticker S placed on the placement unit 3) from the imaging unit 5, and performs image analysis. By doing so, it functions as a determining unit that determines what type of print target is placed on the placement unit 3.
Note that the specific method for determining (detecting) the type of printing object from the image is not particularly limited.

For example, when the image is an image of a finger U including a nail T (nail image), the control unit 11 detects whether or not the finger U is included in the image by analyzing the image. For example, by setting the placement part 3 in a color such as black that can be clearly distinguished from the skin, it is possible to determine the presence or absence of a finger from the difference in color, brightness, etc. The control unit 11 also detects a nail outline that defines a nail area that can be distinguished from the finger U based on differences in brightness and the like. Note that if the curvature level and inclination level (the degree of curvature in the nail width direction and the degree of inclination of the nail T) of the nail T can be detected, it is preferable to also detect these.
Further, the control unit 11 serving as a determining unit determines that the printing target is a sticker S if the shape of the printing area (that is, the printing target surface of the printing target) is rectangular based on the image of the printing target, and determines that the printing target is a sticker S. If the object is a circular or elliptical shape other than the above, it is determined that the object to be printed is a nail chip Nt. Further, various factors such as size in addition to shape may be taken into consideration in the determination.

In addition, for example, if the camera 51 of the photographing unit is to take moving images that can be displayed in live view, the printing target is photographed as a moving image or continuously shot images, etc., and the presence or absence of movement is detected, and the presence of movement is detected. If there is any movement, it may be determined that it is a living body (nail T), and if there is no movement, it may be determined that it is a non-living body (that is, a nail tip Nt or a sticker S).
In addition, a biological sensor such as a blood flow sensor is provided in the finger receiving part 31 of the placing part 3, and if there is a biological reaction (blood flow, etc.), it is determined that it is a living body (nail T), and if there is no movement, it is determined that it is a living body (nail T). It may be determined that the object is not a living body (that is, a nail tip Nt or a sticker S).

The control unit 11 also functions as a detection unit that detects the type of ink cartridge 41 (print head) used for printing. Specifically, the type information of the ink cartridge 41 (print head) provided in the printing mechanism 4 is acquired, and the type is determined.
The method by which the control unit 11 detects the type of the ink cartridge 41 is not particularly limited, but for example, when the ink cartridge 41 is installed in the holder 42, a sensor or switch (not shown) on the holder 42 side detects the type of the ink cartridge 41. It is possible to read whether the device is attached, and the read result is sent to the control unit 11 for acquisition.
Note that when the type information of the ink cartridge 41 (print head) is read when the ink cartridge 41 is installed in the holder 42, it is stored in the storage unit 12 or the like, and when the ink cartridge 41 is removed from the holder for replacement etc. It remains readable until it is read out. When a new ink cartridge 42 is installed in the holder 42, the type information is reset.

Further, the control unit 11 of the present embodiment determines whether the printing target object (type of printing target object) determined by the determining unit and the type of the ink cartridge 41 (print head) detected by the detecting unit correspond to each other. It functions as a correspondence determination unit that determines the For example, if it is determined that the printing target set on the placement unit 3 is a nail T, and the ink cartridge 41 installed in the holder 42 is the first cartridge 41a for nail T printing, the control The unit 11 determines that both correspond. On the other hand, for example, when it is determined that the printing target set on the mounting section 3 is a sticker S, and the ink cartridge 41 installed in the holder 42 is the second cartridge 41b for nail chip printing, The control unit 11 determines that the two are not compatible.

Note that when it is determined that the printing target is a nail T (living body) and the type of ink cartridge 41 (print head) is not compatible with a living body, the control unit 11 does not permit the printing operation. The printing mechanism 4 is controlled as follows.
Also, if it is determined that the printing target is not a nail T (living body) (for example, the printing target is a nail chip Nt), and the type of the ink cartridge 41 (print head) does not correspond to something other than a living body. In this case, the control unit 11 notifies the user of the determination result by displaying the determination result on the display unit 23 serving as a notification unit, and then permits the printing mechanism 4 to perform a printing operation.

Ink that is not compatible with the nail T (living body) may contain components that are not necessarily safe to apply to the human body. Therefore, if the ink cartridge 41 (second cartridge 41 or third cartridge 41c) for printing on the nail tip Nt or sticker S is set in the holder 42, it will not be compatible with the nail T (living body). Printing is not performed until an appropriate ink cartridge 41 (the first print cartridge 41a corresponding to the nail T) is set in the holder 42 so that ink that has not been applied is not applied to the nail T (living body). .
On the other hand, when the object to be printed is a nail chip Nt or a sticker S, even if printing is performed by the first cartridge 41a corresponding to the nail T, there will be only a difference in color development, appearance, etc., and safety is Since there is no problem, there is no need to stop printing if the user understands and accepts the possibility that the finished product may not be as expected because the ink is not compatible with the printing target. If the object to be printed is other than the nail T (living body), by making such a flexible solution, for example, only the ink cartridge 41 (first cartridge 41a) for printing the nail T is prepared, but it is possible to print on a sticker. If the user wants to try printing on S or the like, it is possible to flexibly respond to the user's needs.

[Terminal device configuration]
The terminal device 7 is, for example, a portable terminal device such as a smartphone, a tablet-type terminal device (hereinafter referred to as a "tablet PC (Personal Computer)", or a mobile phone). The computer is not limited to this, and may be, for example, a notebook PC, a desktop PC, or the like.

As shown in FIG. 5, the terminal device 7 includes a control device 70, an operation section 73, a display section 74, a communication section 75, and the like.

The operation unit 73 is capable of performing various inputs, settings, etc. in response to user operations, and is, for example, a touch panel integrally provided with a display (not shown) of a display unit 74 described later.
In this embodiment, the operation unit 73 inputs various instructions from the user regarding print control processing implemented by the printing apparatus 1 (and the terminal device 7 that cooperates with the printing apparatus 1).
When the operation section 73 is operated, an input signal corresponding to the operation is transmitted to the control section 71, and the control section 71 performs control according to the operation signal.

The display unit 74 includes a display (flat display) such as a liquid crystal display, and displays various images, information, message screens, etc. on the display based on display signals input from the control unit 71.
The display of the display unit 74 of this embodiment may be configured integrally with a touch panel, and in this case, various operation screens are displayed on the touch panel under the control of the control unit 71. The user can perform various operations such as inputting and setting by touching the touch panel, and the touch panel functions as an operation unit 73 that accepts touch operations by the user and performs various inputs. Note that the operation unit 73 for performing various input/setting operations is not limited to a touch panel.

Furthermore, the terminal device 7 receives various information from an external device such as the printing device 1 and outputs original image data of a design to be printed on the nail T (nail design), etc. to the printing device 1. Data is sent and received between the printing device 1 and the like through wireless communication based on short-range wireless communication standards such as Bluetooth (registered trademark) and Wi-Fi, communication using wireless LAN, etc., and communication using wired connection. The terminal device 7 includes a communication section 75 that supports such communication.
Note that the specific communication method etc. are not particularly limited. It may be possible to select one of several communication methods as appropriate.

The control device 70 is a computer including a control unit 71 having a processor such as a CPU (not shown), a storage unit 72 having a ROM, a RAM, etc. (none of which are shown), and the like. The storage unit 72 stores various programs, various data, etc. for operating each part of the terminal device 7.

The control unit 71 reads out a designated program from among the system programs and application programs stored in the storage unit 72, develops it in the work area of the RAM, executes various processes according to the program, and operates the terminal device 7. control each part of the
In particular, in this embodiment, a nail print application program 721 (hereinafter referred to as “nail print AP”) is stored in the storage unit 72, and the control unit 71 controls the printing device 1 in cooperation with such a program. Various functions related to the nail print used are realized.
Specifically, the control unit 71 functions as a display control unit that controls the operation of the display unit 74, a communication control unit that controls the operation of the communication unit 75, and the like.

Further, in this embodiment, original image data (RGB data) of a design (nail design) is stored in the storage unit 72, and the control unit 71 acts as a display control unit to display the design on the display unit 74 and allow the user to select it. I urge you to do so. When one of the designs is selected, the original image data of the design is transmitted to the printing device 1 via the communication unit 75.

[Print control processing, printing device operation]
Next, the operation of the printing apparatus and print control processing in this embodiment will be explained with reference to FIG. 6 and the like.
When performing nail printing using the printing apparatus 1 of this embodiment, the user operates the operation unit 22 (operation button) of the printing apparatus 1 to turn on the power and start the printing apparatus 1. Further, the terminal device 7 is also powered on and execution of the nail print process is selected from the operation section 73 of the terminal device 7. As a result, the nail print AP 721 is activated.
Note that in this embodiment, when the printing device 1 and the terminal device 7 are started, the user can perform an input operation to select and set a design (nail design) to be printed on the nail T from the operation unit 73 or the like of the terminal device 7. can. When a design is selected, the original image data (RGB data) of the design is transmitted to the printing device 1. The printing device 1 generates print data (for output) corresponding to the print target for the design.

FIG. 6 is a flowchart showing print control processing in this embodiment.
As shown in FIG. 6, when printing is performed by the printing device 1, first the camera 51 photographs the printing target set on the placement section 3, and the control section 11 acquires the photographed image ( Step S1).
The control unit 11 performs image analysis on the acquired image (including the nail image) and determines whether or not the finger U is detected from the image (step S2). That is, the control unit 11 acts as a determining unit and determines whether or not the printing target placed on the mounting unit 3 is a living body.

If a finger can be detected from the image as a result of image analysis or the like (step S2; YES), the control unit 11 judges (discriminates) that the printing object is a nail T, which is a living body (step S3). Note that the method of detecting a finger from an image is not particularly limited. For example, the presence or absence of a finger is judged from the difference in color or brightness with the placement unit 3. For example, if the finger receiving portion 31 of the placement unit 3 is colored black, it can be clearly distinguished from the color of the skin of the finger.
On the other hand, if a finger cannot be detected (step S2; NO), the control unit 11 further judges whether the shape of the printing object placed on the placement unit 3 is a nail tip Nt (simply referred to as "tip" in FIG. 6) (step S4). As described above, the nail tip Nt and the sticker S are white or other colored members and are relatively easy to distinguish from the surrounding members. Therefore, the shape of the printing object can be recognized by looking at the shape of the white or other portion in the image. If the shape of the printing object is an oval or other shape similar to a nail T as a result of image analysis or the like (step S4; YES), the printing object is judged to be a nail tip Nt (step S5), and if the shape is other than that (e.g., rectangular, etc.) (step S4; NO), the printing object is judged to be a sticker S (step S6).

When it is determined (determined) that the printing target is the nail T in step S3 described above, the control section 11 further functions as a detection section to detect the type of ink cartridge used for printing. Specifically, type information of the ink cartridge 41 currently installed in the holder 42 is acquired from information stored in the storage unit 12 or the like (step S7).
Then, the control section 11, as a correspondence determination section, determines whether or not the ink cartridge 41 currently installed in the holder 42 is compatible with the object to be printed (here, the nail T) (step S8). If the ink cartridge 41 corresponds to the object to be printed (in this example, if the first cartridge 41a is attached to the holder 42, step S8; YES), the control unit 11 controls the printing mechanism 4. is controlled to perform printing processing (step S9), and the series of processing ends.

On the other hand, if the ink cartridge 41 does not correspond to the object to be printed (in this example, if the second cartridge 41b or the third cartridge 41c is attached to the holder 42, step S8; NO), the control unit 11 notifies the user by, for example, displaying on the display screen of the display unit 23, which is a notification unit, that the ink cartridge 41 corresponding to the object to be printed (here, the nail T) is not installed in the holder 42; A message or the like prompting the user to replace the ink cartridge 41 with one corresponding to the object to be printed (here, the nail T) is displayed on the display unit 23 (step S10). Note that when prompting the user to replace the ink cartridge 41, information such as the name and model number of the ink cartridge to be replaced may also be displayed for easy understanding by the user.

Then, the control unit 11 determines whether or not the message has been displayed repeatedly for a predetermined number of times (step S11), and if the predetermined number of times has not been reached (step S11; NO), the process returns to step S7 and the message is displayed in the holder 42. Check the correspondence between the installed ink cartridge 41 and the object to be printed.
On the other hand, if the predetermined number of times has been reached (step S11; YES), the control unit 11 displays an error message such as "Printing cannot be continued" on the display unit 23 or the like, stops printing, and ends the process. Note that the "predetermined number of times" referred to in step S11 is not particularly limited, and is, for example, five times. Further, it is determined that an error has occurred, and is not limited to a predetermined number of repetitions; for example, if the ink cartridge 41 is not replaced even after a predetermined period of time such as 5 minutes has elapsed, the process proceeds to step S12 for error processing. Good too.

Furthermore, even when the printing target is something other than a living body (nail T) (that is, in the case of step S5 or step S6), the control unit 11, as a detection unit, detects the type of ink cartridge used for printing. To detect. Specifically, type information of the ink cartridge 41 currently installed in the holder 42 is acquired from information stored in the storage unit 12 or the like (step S13).
Then, the control unit 11, as a compatibility determining unit, determines whether or not the ink cartridge 41 currently installed in the holder 42 is compatible with the printing target (here, the nail chip Nt or the sticker S) (step S14). If the ink cartridge 41 corresponds to the object to be printed (step S14; YES), the control unit 11 controls the printing mechanism 4 to perform the printing process (step S9), and executes a series of processes. finish. Note that the case where the ink cartridge 41 corresponds to the printing object means, for example, when the printing object is a nail chip Nt, the second cartridge 41b is attached to the holder 42, or the case where the printing object is a sticker. If it is S, it means that the third cartridge 41c is attached to the holder 42.

On the other hand, if the ink cartridge 41 does not correspond to the object to be printed (in this example, if the first cartridge 41a or the like is attached to the holder 42, step S14; NO), the control section 11 controls the notification section. The user is notified by, for example, displaying on the display screen of the display unit 23 that the ink cartridge 41 corresponding to the object to be printed (here, the nail chip Nt or the sticker S) is not installed in the holder 42, and printing is performed. A message or the like prompting the user to replace the ink cartridge 41 with one corresponding to the target object (here, the nail chip Nt or the sticker S) is displayed on the display unit 23 (step S15). Note that, as in step S10, it is preferable to also display information such as the name and model number of the ink cartridge to be replaced when prompting the user to replace the ink cartridge 41.

Then, the control unit 11 determines whether or not a predetermined permission operation has been performed, for example (step S16), and if there is no permission operation (step S16; NO), the process returns to step S13, and the ink attached to the holder 42 is Check the correspondence between the cartridge 41 and the object to be printed.
On the other hand, if the permission operation is performed (step S16; YES), the control unit 11 controls the printing mechanism 4 to perform printing processing (step S9), and ends the series of processing.
Note that the predetermined "permitted operation" here refers to a case where, for example, after an error message is displayed on the display unit 23 or the like to notify the user, the user performs an operation that prompts printing, such as pressing a print button. . Furthermore, if a predetermined period of time (for example, 1 minute, etc.) has elapsed after the error message is displayed, it is assumed that the user has tacitly approved the printing, and the printing process (step S9) is assumed to have been performed. ).

In this way, it is possible to reliably prevent printing on the nail T with ink intended for printing on non-living objects such as nail tips Nt, and also prevent printing on non-living objects such as nail tips Nt. In some cases, it is possible to respond flexibly by not requiring strict compliance with the ink cartridge 41.

As described above, the printing device 1 including the control device 10 of the present embodiment has a determining unit that determines whether the printing target is a living body (for example, a fingernail) and also determines the type of the ink cartridge 41 used for printing. The control unit 11 is provided as a correspondence determination unit that detects and determines whether or not the identified printing target object and the detected type of ink cartridge 41 correspond to each other.
Since the ink (components of ink, etc.) suitable for printing differs depending on the printing target, it is necessary to check the suitability of the correspondence between the printing target set on the mounting section 3 and the type of ink cartridge 41 installed in the holder 42. By making this determination, printing with ink that is not compatible with the printing target can be avoided in advance. As a result, it is possible to perform appropriate printing with a finish as originally expected.

Furthermore, as in the present embodiment, when a notification section (display section 23 in the embodiment) is provided to notify the determination result of the control section 11 as a compatibility determination section, it is possible to alert the user before printing. , it is possible to make the user aware that the printing target is about to be printed with ink that is not compatible with the printing target.
Therefore, it is possible to avoid printing with ink that is not compatible with the object to be printed, and to perform appropriate printing.

In this embodiment, the living body is a human nail T.
The nail T is a delicate part of the body, and if ink containing ingredients that are harmful to the human body is mistakenly used for printing, there is a risk that the nail T will be unintentionally damaged.
In this regard, in the present embodiment, if printing is to be performed with ink that is not suitable for the printing object, the user can be notified in advance, and therefore printing with ink that is not suitable for printing on the nail T can be avoided.

Further, in this embodiment, the printing objects other than the living body include the nail tip Nt and the sticker S.
There are differences in ink spread, color development, etc. depending on the material of the printing object, and if printing on an incompatible object, high-definition printing results may not necessarily be obtained.
In this regard, since it is determined whether the ink cartridge 41 corresponding to the nail chip Nt or the sticker S is installed, it is possible to print with a good finish using appropriate ink.

Further, in the present embodiment, when the control unit 11 as a discrimination unit determines that the printing target is a living body (nail T), the type of the detected ink cartridge 41 corresponds to the living body (nail T). Otherwise, printing is not permitted.
As mentioned above, ink that is not for nail T printing may contain components that may have an adverse effect on the human body. In this regard, if the printing target is the nail T, printing will not be performed even if the user does not actively direct the user to pay attention to the print, thereby ensuring that the nail T will not be printed with incompatible ink. can be prevented.

Further, in this embodiment, when the control unit 11 serving as the discrimination unit determines that the printing target is a non-living object (that is, for example, a nail chip Nt or a sticker S), the correspondence determination unit notifies the determination result of the determination. The printing operation is permitted after the notification is made by displaying it on the display section 23, which is the section.
For example, in the case of nail tips Nt and stickers S, if printing is done with ink for nail T printing, the appearance such as color development may differ from what was originally planned, but there are important issues such as safety for the human body. No problems will arise. Therefore, in this case, the user's intention to print is respected even if the appearance is slightly inferior, and the printing is performed. This makes it possible to respond flexibly even when the user does not have the ink cartridge 41 corresponding to the object to be printed.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these embodiments and can be modified in various ways without departing from the spirit thereof.

For example, in this embodiment, one ink cartridge 41 is mounted on the holder 42, but two or more ink cartridges 41 may be mounted on one holder 42, for example. For example, as shown in FIGS. 7 and 8, one holder 42 includes an ink cartridge 41 for printing nail T (first cartridge 41a) and an ink cartridge 41 for printing other than nail T (for example, a second cartridge for printing nail tip Nt). Both the second cartridge 41b and the third cartridge 41c for printing the sticker S may be installed.

In this case, even if the ink cartridge 41 corresponding to the object to be printed is not set to be used for printing, the control unit 11 can automatically switch the ink cartridge 41 when the object to be printed is determined, and the user can There is no need to request replacement of the ink cartridge 41. In this case, the switching may be displayed on the display unit 23 or the like serving as a notification unit to notify the user, or the process may proceed without notification. Note that in this case, a configuration may be adopted in which the display section 23 serving as the notification section is not provided.
Note that when a plurality of types of ink cartridges 41 are mounted on the holder 42, a changeover switch or the like may be provided so that the user can input a changeover instruction. When switching on the user side, if an ink cartridge 41 inappropriate for use in printing is selected, the control unit 11 displays a message on the display unit 23 etc., and inputs an instruction to the user to switch the ink cartridge 41. You may also encourage them to do this.

Further, even when two or more ink cartridges 41 can be mounted on one holder 42, the plurality of ink cartridges 42 mounted on the holder 42 may be of the same type or may be of different types.
For example, when the object to be printed is a nail T, a print head for design printing and a print head for base printing may be attached to one holder 42 . In this way, it is possible to print continuously from the base to the design.

Further, the number of holders 42 included in the printing apparatus 1 is not limited to one, and a plurality of holders 42 may be provided, and the ink cartridge 41 may be mounted on each holder 42. In this case, the ink cartridges 41 that can be installed may be different depending on the holder 42, and by detecting which holder 42 the ink cartridge 41 is installed, the type of ink cartridge 41 that can be used for printing can be determined. You can make it easy to understand.

Note that there may be cases where none of the holders 42 that can be mounted with a plurality of holders 42 have an ink cartridge 41 that corresponds to the object to be printed, or where all of the ink cartridges 41 that are installed in the plurality of holders 42 do not correspond to the object to be printed. If the ink cartridge 41 has not been replaced, the control unit 11 displays this on the display unit 23 or the like serving as a notification unit, and prompts the user to replace the ink cartridge 41.

In addition, in this embodiment, even when printing on areas other than the nail T, by providing auxiliary tools 34a and 34b on the placing section 3, the same position as when printing on the nail T (in the width direction and depth direction within the device) is provided. Although the case where printing is performed at the position (position ) is illustrated, the position at which the printing target other than the nail T is placed is not limited to the example.
For example, if the ink cartridge 41 (print head) of the printing mechanism 4 is configured to be movable not only in the X direction and the Y direction but also in the height direction (Z direction in FIGS. 1 to 4), the nail tip Printing may be performed by arranging the Nt and the sticker S, for example, in a space next to the mounting section 3 instead of the mounting section 3. In this case as well, the distance between the highest part of the nail tip Nt or the seal S and the ink discharge surface 411 of the ink cartridge 41 is the same as the distance between the highest part of the nail T and the ink discharge surface 411 of the ink cartridge 41. It is preferable that the distance be adjusted to be approximately equal to the distance between the two.

Furthermore, if the printing object is set to be placed in a different location for each printing object, the printing object set in the printing device 1 may be determined (discerned) based on where it is placed.

In addition, different marks are attached to the surface of the finger receiving section 31 of the placing section 3 and the surfaces of the auxiliary tools 34a and 34b, respectively, and by simply reading these marks, it is possible to determine what the printing target set in the printing device 1 is. It may be possible to make it possible to determine whether By making a mark that can be easily distinguished from the image, it is possible to easily determine the type of printing object (that is, whether it is a nail T, a nail tip Nt, or a sticker S).

Furthermore, the method of recognizing what the printing object set in the printing device 1 is is not limited to a method in which the control unit 11, as an object recognition means for recognizing the surface condition of the printing object, automatically recognizes the printing object from an image captured of the placement unit 3.
For example, the user may be able to select and input from the operation unit 22 or the like whether to perform printing (main printing) on a nail T or test printing on a dummy material such as a nail tip Nt or a sticker S. In this case, the control unit 11 recognizes the type of printing based on the operation signal input from the operation unit 22 or the like, and recognizes whether the printing object is a nail T or a nail tip Nt or a sticker S.

In addition, the printing target may be determined only as to whether it is a living body (nail T) or something else, and other than the printing target may not be particularly distinguished. In this case, two types of ink cartridges 41 may be prepared: one for nail T printing and one for other purposes.

Furthermore, in this embodiment, when the printing target is other than a living body (nail T), printing is permitted (continued) if the user approves, but when the printing target is other than a living body (nail T), printing is allowed (continued). Alternatively, printing may not be allowed unless the ink cartridge 41 is compatible. Furthermore, even for printing objects other than nails, the handling may be changed depending on the type of printing object. For example, in the case of a nail tip Nt, printing may be permitted even if a nail T printing cartridge (first cartridge 41a) is installed, but in the case of a sticker S, printing may be permitted even if a nail T printing cartridge (first cartridge 41a) is installed. Measures may be taken depending on the degree of impact on the finished product, such as not allowing printing until the third cartridge 41c) is installed.

Further, in this embodiment, printing is not permitted when the printing target is a living body (nail T). For example, printing is not permitted when the second cartridge 41b is installed. If the cartridge 41c is installed, printing may be permitted if the user requests it, or printing may be permitted depending on the components of the ink.
In either case, it is preferable that the finished image and various effects of printing using the currently installed ink cartridge 41 are sufficiently shown to the user on the display section 23 or the like serving as a notification section.

In the above embodiment, the original image data of the design (nail design) is stored in the storage unit 72 of the terminal device 7, but the original image data of the design (nail design) is not limited to being stored in the storage unit 72. For example, it may be a data management server capable of transmitting and receiving information to and from the printing device 1 or the terminal device 7, a virtual server on the cloud, or the like that can be accessed via the Internet. In this case, more data can be prepared, resulting in a wider variety of designs.
The original image data of the design (nail design) may be stored in the storage unit 12 of the printing device 1. In this case, printing of the nail design can be completed using only the printing device 1 even in a place without a communication environment.

In the embodiment described above, the control unit 11 of the printing apparatus 1 includes a determination unit that determines whether the object to be printed is a living body (for example, a fingernail), and a detection unit that detects the type of the ink cartridge 41 used for printing. , a correspondence determining unit that determines whether or not the determined printing target object corresponds to the detected type of ink cartridge 41 has been exemplified; however, in the case where these functional units are the control unit 11. but not limited to. For example, the control unit 71 of the terminal device 7 that can communicate with the printing device 1 may function as a determination unit, a detection unit, and a correspondence determination unit.
In this case, when an image is acquired by the photographing unit 5 of the printing device 1, this image data is sent to the terminal device 7, and the control unit 71 performs image analysis and the like.
In this way, when various processes are performed outside the printing device 1, the printing device 1 only needs to be able to operate the photographing section 5 and the printing mechanism 4, and the configuration of the control device 10 etc. can be simplified. can be taken as a thing.

In addition, in this embodiment, it is assumed that the terminal device 7 is a mobile terminal such as a smartphone owned by the user, but the terminal device 7 is not limited to being owned by the user himself. For example, if the printing device 1 is a device placed in a store, the terminal device 7 may be an operation terminal provided in the store. Furthermore, the terminal device 7 does not have to be a device separate from the printing device 1, and may be, for example, an operation terminal attached to the printing device 1.

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 equivalent ranges thereof. .
