[0016] FIG. 1 is a block diagram illustrating a printing device (hereinafter referred to as "printing device 100") and an auxiliary device 200 that can be coupled to various auxiliary devices according to one embodiment of the present invention.

[0017] Referring to FIG. 1, a printing device 100 may be coupled or connected to an auxiliary device 200 . The printing device 100 may perform a printing function, which is a basic function using inkjet printing technology. The printing device 100 may recognize the assistive device 200. For example, the printing device 100 may recognize the assistive device 200 using various sensors (infrared sensors, photointerrupters, capacitance sensors, resistance sensors, etc.) or wired and wireless (RFID, USB cable, etc.) communication technologies. Depending on the recognized assistive device 200, the functions of the printing device 100 and a terminal communicatively connected to the printing device 100 may be changed. A user may also select the assistive device 200 in an app on a user terminal communicatively connected to the printing device 100. The printing device 100 includes a main body 110, a coupling unit 120, a recognition unit 130, and a control unit 140. The main body 110 forms the outer shape of the printing device 100. The main body 110 may be made of a plastic or metal material. The coupling part 120 is formed on the main body 110 so as to be physically coupled to the assistive device 200. The recognition part 130 is formed on the main body 110 so as to recognize the assistive device 200 and determine whether the coupling part 120 and the assistive device 200 are coupled or not. When the recognition unit 130 recognizes the assistive device 200, it determines that the connecting unit 120 and the assistive device 200 are connected. When the recognition unit 130 recognizes that the assistive device 200 is not connected to the connection unit 120, the control unit 140 sets the assistive device 200 to a state in which the basic function is executed. In addition, when the recognition unit 130 recognizes that the auxiliary device 200 is connected to the connection unit 120, the control unit 140 sets the auxiliary device 200 to a state in which an individual function that is changed from the basic function is executed according to the connected auxiliary device 200.

[0018] Although not shown, the printing apparatus 100 may further include an ejection port for ejecting ink and a storage box for storing the ink. The ejection port may be formed on the outer surface of the printing apparatus 100 so as to be exposed to the outside. The storage box may be located inside the printing apparatus 100.

[0019] Although not shown, the control unit 140 may include a memory and a processor for controlling functions of the printing device 100. The memory may store at least one of information and data input to the printing device 100, information and data required for functions executed by the processor, and data generated in response to execution of the processor. For example, memory may store algorithms and programs for ink printing, algorithms or programs for printing ink onto skin or hair, etc. Memory should be taken to mean non-volatile storage devices that continue to maintain stored information even when power is removed, as well as volatile storage devices that require power to maintain stored information. The memory may temporarily or permanently store data processed by the processor. The memory may include a volatile storage device that requires power to maintain stored information, as well as a magnetic storage medium or a flash storage medium, although the scope of the present invention is not limited thereto. The processor is configured to execute a program stored in a memory. For example, the processor may execute a skin printing program, a hair printing program, etc. stored in the memory. The processor may include various types of devices that control and process data. The processor refers to a data processing device built into hardware having physically structured circuitry to execute functions expressed in code or commands contained in a program. By way of example, the processor may be embodied in the form of a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., but is not limited to these.

[0020] The auxiliary device 200 is used to expand and smoothly perform the functions of the printing apparatus 100, and various auxiliary devices may be used depending on the usage form. For example, the auxiliary device 200 may be a skin guide, a hair guide, a makeup (color makeup) guide, a multi-path guide, or a camera accessory. The auxiliary device 200 may have a shape for guiding ink ejected by the printing apparatus 100 to an area such as skin or hair.

[0021] Various methods can be applied to connect the printing device 100 and the auxiliary device 200. In other words, the printing device 100 can be connected to the auxiliary device 200 using a snap-in connection method, a screw connection method, or the like. For example, one surface of the printing device 100 may be formed as a bolt-type fastening structure, and one surface of the auxiliary device 200 may be formed as a nut-type fastening structure, and in this case, one surface of the printing device 100 and one surface of the auxiliary device 200 may be coupled to each other so as to abut against each other. In this manner, one surface of the printing device 100 and one surface of the auxiliary device 200 may be formed as a structure that can be fastened to each other so that no empty space is generated between the printing device 100 and the auxiliary device 200 .

[0022] 2 and 3 are diagrams illustrating a process in which the recognition unit 130 of the printing device 100 recognizes the assistive device 200. FIG.

[0023] 2, the recognition unit 130 may include a communication module 131. The recognition unit 130 may recognize the auxiliary device 200 connected thereto through wired or wireless communication via the communication module 131. For this purpose, the auxiliary device 200 may also be provided with a separate communication module 210. The communication module 131 transmits and receives information to and from the outside, where the outside may be the auxiliary device 200, an external server, or a terminal. The communication module 131 may include hardware and software necessary to transmit and receive signals, such as control signals or data signals, to and from other network devices via wired or wireless connections.

[0024] An example of how the printing device 100 recognizes the assistive device 200 using communication technology is as follows. The printing device 100 may be coupled to the auxiliary device 200 through proximity communication technology. The printing device 100 may store information related to the auxiliary device 200 in each tag using proximity communication technology such as RFID, and may configure a module or circuit that recognizes the auxiliary device within the device. Thereafter, the printing device 100 can read the tag information of the auxiliary device 200 when coupled with the auxiliary device 200 to distinguish between the respective auxiliary devices 200 . In addition, the printing device 100 can be connected to the auxiliary device 200 through USB cable communication. A USB cable connected to the auxiliary device 200 is directly connected to the printing device 100, and the printing device 100 can read information about the auxiliary device 200. If the auxiliary device 200 requires power, the power can be supplied from the printing device 100. Alternatively, power can be supplied to the printing device 100 and the auxiliary device 200 using a separate power source. The printing device 100 may be connected to the auxiliary device 200 through RF communication. The auxiliary device 200 includes an RF communication module, and the printing device 100 may perform wireless communication. This allows the printing device 100 to distinguish the type of auxiliary device 200 and perform individual functions according to the connected auxiliary device.

[0025] 3 , the recognition unit 130 may include a sensing module 132 equipped with a sensor 1321 attached to the main body 110. The recognition unit 130 may recognize the auxiliary tool 200 by recognizing, with the sensing module 132, a recognition object 220 that may be attached to the auxiliary tool 200 and recognized by the sensor 1321. At this time, the recognition unit 130 recognizes the assistive devices 200 having different types of recognition objects 220 as different assistive devices 200 . Here, the sensor 1321 may be, but is not limited to, a capacitive touch sensor, a Hall sensor, or a photo sensor.

[0026] An example of how the printing device 100 recognizes the auxiliary device 200 using a sensor is as follows. The printing device 100 can be automatically connected to the assistive device 200 through a connection method using a capacitive touch sensor. In this case, a circuit for recognizing a capacitive touch is configured in the printing device 100. A material that can be recognized by the touch sensor is formed in the assistive device 200. The material is located in an area of ​​the assistive device 200 corresponding to the position of the touch sensor disposed in the recognition unit 130. The number of metals can be adjusted in various ways depending on the type of assistive device 200. For example, an assistive device with one metal and an assistive device with two metals can be recognized as different assistive devices.

[0027] The printing device 100 can be connected to the auxiliary device 200 through a connection method using a Hall sensor. In this case, a Hall sensor circuit is configured in the printing device 100. A magnet is disposed in the auxiliary device 200. The magnets are placed in areas of the assistive device 200 that correspond to the positions of the Hall sensors. By adjusting the number of magnets depending on the type of assistive device 200, various assistive devices can be recognized and their functions can be distinguished. For example, an assistive device with one magnet and an assistive device with two magnets can be recognized as different assistive devices.

[0028] The printing device 100 may be connected to the auxiliary device 200 through a connection method using a photosensor. In this case, a circuit to which a photosensor is added is configured in the printing device 100. A structure capable of blocking the photosensor is disposed in the auxiliary device 200. Types of the auxiliary device 200 may be distinguished depending on the number of structures that can be blocked.

[0029] FIG. 4 is a flowchart illustrating the operation process of the printing device 100.

[0030] 4, the printing device 100 first checks a sensor or a communication module that detects an auxiliary device (S11), and then determines whether an auxiliary device is connected or present (S12). If the auxiliary device 200 is not connected to the printing device 100 and is not recognized, the printing device 100 performs basic functions (S13). When the auxiliary device 200 is coupled to the printing device 100 and the auxiliary device 200 is recognized, the printing device 100 may change the functionality of an application communicatively coupled to the printing device 100 depending on the type of the auxiliary device 200. The application may be an application driven by a terminal communicatively connected to the printing device 100 . In addition, when the auxiliary device 200 is connected to the printing device 100 and the auxiliary device 200 is recognized, the function of the printing device 100 is changed to an individual function according to the type of the auxiliary device 200.

[0031] As an example, when the recognition unit 130 recognizes that the skin guide has been combined with the combining unit 120, the control unit 140 may set the skin printing function according to the preset skin printing algorithm corresponding to the skin guide as an individual function. As another example, when the recognition unit 130 recognizes that the hair guide has been connected to the hair guide connection unit 120, the control unit 140 may set a hair printing function according to a preset hair printing algorithm corresponding to the hair guide as an individual function. As another example, when the recognition unit 130 recognizes that the makeup guide is combined with the combining unit 120, the control unit 140 may set the makeup printing function according to a preset makeup printing algorithm corresponding to the makeup guide as an individual function. As another example, when the recognition unit 130 recognizes that the multi-pass guide is connected to the connection unit 120, the control unit 140 may set the multi-pass printing function according to a pre-set multi-pass printing algorithm corresponding to the multi-pass guide to an individual function. As another example, when the recognition unit 130 recognizes that a camera accessory is connected to the connection unit 120, the control unit 140 may set the camera image printing function according to a preset camera image printing algorithm corresponding to the camera accessory as an individual function.

[0032] 5 to 20 are diagrams illustrating the function of the printing device 100 in combination with various auxiliary devices according to an embodiment of the present invention. With reference to Figures 5 to 20, the function of the printing device 100 in combination with the various ancillary devices 201, 202, 203, 204, 205 will be described.

[0033] Referring to FIG. 5, the printing device 100 may be coupled to a skin guide 201, which is one of the auxiliary devices 200. Referring to FIG. 6, the operation process of the printing device 100 combined with the skin guide 201 is similar to the operation process described with reference to FIG. However, by combining the printing device 100 with the skin guide 201, the interface and functions of the terminal communicatively connected to the printing device 100 may be changed to match the skin guide 201 (S14a). In accordance with the skin guide 201, the function of the printing device 100 can be changed to a skin printing function according to a preset skin printing algorithm (S15a). 7, the interface displayed on the terminal may be configured as a tattoo image selection interface 701. A user selects one of the tattoo images included in the tattoo image selection interface 701 and places the printing device 100 on or near the skin of the user or another person, so that the printing device 100 can print the selected tattoo image. The skin guide 201 may have a body that forms an outer shape and includes a hollow area in the center. In this case, ink ejected from the ejection opening of the printing device 100 may be injected into the hollow area of ​​the body of the skin guide 201.

[0034] Referring to FIG. 8, the printing device 100 may be coupled to a hair guide 202 which is one of the auxiliary devices 200 . Referring to FIG. 9, the operation process of the printing device 100 combined with the hair guide 202 is similar to the operation process described with reference to FIG. By combining the printing device 100 with the hair guide 202, the interface and functions of the terminal communicatively connected to the printing device 100 can be changed to match the hair guide 202 (S14b). In addition, in accordance with the hair guide 202, the function of the printing device 100 can be changed to a hair printing function according to a preset hair printing algorithm (S15b). 10, the interface displayed on the terminal may be configured as a hairstyle and color selection interface 1001. When one of various hairstyles and one of various hair colors included in the hairstyle and color selection interface 1001 is selected and the printing device 100 is positioned on or near one's own or another person's hair, the printing device 100 may print the selected hair color to match the selected hairstyle (1002 in FIG. 10). Contrary to skin and paper, hair requires a larger amount of ink to be jetted than conventional printing to achieve a good color effect. In the case of hair, the brightness of hair varies from person to person, so the amount of ink printed needs to be adjusted depending on whether the hair is light or dark. Therefore, when the hair guide 202 is attached to the printing device 100, the printing device 100 can correct the printing algorithm based on the color value specified by the user or the color value automatically classified through a photograph. The hair guide 202 may have a body that forms an outer shape and includes a hollow area in the center. In this case, ink ejected from the ejection opening of the printing device 100 may be ejected into the hollow area of ​​the body of the hair guide 202. The hair guide 202 may further include a comb-shaped guide portion that guides the ejected ink and a handle portion that allows a user to easily operate the printing device 100. The user can use the handle portion to position the printing device 100 close to the hair.

[0035] Referring to FIG. 11, the printing device 100 may be coupled to a makeup guide 203, which is one of the auxiliary tools 200. Referring to FIG. 12, the operation process of the printing apparatus 100 combined with the makeup guide 203 is similar to the operation process described with reference to FIG. By combining the printing device 100 with the makeup guide 203, the interface and functions of the terminal communicatively connected to the printing device 100 can be changed to match the makeup guide 203 (S14c). According to the makeup guide 203, the function of the printing device 100 can be changed to a makeup printing function according to a preset makeup printing algorithm (S15c). 13, the interface displayed on the terminal may be configured as a makeup selection interface 1301. When one of various makeup information included in the makeup selection interface 1301 is selected and the printing device 100 is positioned on or near one's own or another person's face, the printing device 100 may print makeup according to the selected information (1002 in FIG. 10). The makeup guide 203 may have a body that forms an outer shape and includes a hollow area in the center. In this case, ink ejected from the ejection opening of the printing apparatus 100 may be ejected into the hollow area of ​​the body of the makeup guide 203.

[0036] Referring to FIG. 14, the printing apparatus 100 may be coupled with a multi-path guide 204, which is one of the auxiliary devices 200. Referring to FIG. 15, the operation process of the printing apparatus 100 combined with the multi-path guide 204 is similar to the operation process described with reference to FIG. By combining the printing device 100 with the multipath guide 204, the interface and functions of the terminal communicatively connected to the printing device 100 can be changed to match the multipath guide 204 (S14d). In addition, the function of the printing apparatus 100 can be changed to a multi-pass printing function according to a preset multi-pass printing algorithm in accordance with the multi-pass guide 204 (S15d). Depending on the multi-pass guide 204 and the multi-pass printing function, the printing apparatus 100 may be embodied to be capable of printing in both the x-axis and the y-axis.

[0037] Referring to FIG. 16, the printing device 100 may be coupled to a camera accessory 205, which is one of the accessories 200. Referring to FIG. 17, the operation process of the printing device 100 combined with the camera accessory 205 is similar to the operation process described with reference to FIG. When the printing device 100 is coupled to the camera accessory 205, the interface and functions of the terminal communicatively connected to the printing device 100 can be changed to match the camera accessory 205 (S14e). In accordance with the camera accessory 205, the function of the printing device 100 can be changed to a camera image printing function according to a preset camera image printing algorithm (S15e). The camera accessory 205 may have a body that defines an outer shape and has a hollow area in the center, in which ink ejected from the ejection openings of the printing device 100 can be injected into the hollow area of ​​the body of the camera accessory 205.

[0038] 18 and 19, when the camera accessory 205 and the printing device 100 are connected, the printing device 100 prints the first line based on the original image (S21), compares the image of the already printed portion with the existing original image through the camera to calculate the position and angle (S22), and may continue printing by adjusting the position and angle of the printing device 100 according to the calculated position and angle (S23).

[0039] An example of the process of combining, recognizing, and operating the skin guide 201, hair guide 202, and makeup guide 203 with the printing device 100 will be described with reference to FIG. First, the printing device 100 checks the sensor or communication module for detecting the auxiliary device 200 (S31). Next, the printing device 100 recognizes the auxiliary device 200 and determines whether or not a connection with the auxiliary device 200 has been made (S32). If it is determined that the printing device 100 is not coupled to the auxiliary device 200, the printing device 100 executes basic functions (S41). If it is determined that the printing device 100 is coupled to the auxiliary device 200, it determines whether the auxiliary device 200 is a skin guide 201 (S33), and if it is not a skin guide 201, it determines whether it is a hair guide 202 (S34), and if it is not a hair guide 202, it may determine whether it is a makeup guide 203 (S35).

[0040] If the combined auxiliary device 200 is a skin guide 201, the printing device 100 may adjust the printing amount according to the skin tone and the type of image to be printed on the skin (S42). Tattoo-related images can be displayed and edited using a terminal connected to the printing device 100 (S51). If the connected auxiliary tool 200 is a hair guide 202, the printing device 100 may adjust the printing amount according to the hair tone (S43). The hair-related image can be displayed and edited using a terminal connected to the printing device 100 (S52). If the connected auxiliary tool 200 is a makeup guide 203, the printing device 100 can adjust the amount of printing depending on the type of makeup (eyebrows, eyelids, etc.) (S44). Makeup-related images can be displayed and edited using a terminal connected to the printing device 100 (S53).

[0041] FIG. 21 is a flowchart showing the procedure of a method for operating a printing apparatus that can be coupled with various auxiliary devices (hereinafter referred to as the "method for operating a printing apparatus") according to another embodiment of the present invention. The method of operating a printing apparatus described below can be performed by the printing apparatus (100 in FIG. 1) previously described with reference to Figures 1 to 20. Therefore, the details of the embodiments of the present invention previously described with reference to Figures 1 to 20 are equally applicable to the embodiments described below, and the details that overlap with the above description will be omitted below. The steps described below are not necessarily performed in order; the order of the steps can vary and the steps can be performed substantially simultaneously.

Here, the main body, the connecting part, the recognition part, and the control part may be the main body (110 in FIG. 1), the connecting part (120 in FIG. 1), the recognition part (130 in FIG. 1), and the control part (140 in FIG. 1), respectively, shown in FIG. 1.

[0043] The method for operating a printing device includes an auxiliary device recognition step S110 and a function setting step S120. The auxiliary device recognition step S110 is a step in which the recognition unit recognizes the auxiliary device and determines whether the connection unit and the auxiliary device are connected. The function setting step S120 is a step in which the control unit sets the auxiliary device to a state in which a basic function is executed if the recognition unit recognizes that the auxiliary device is not connected to the connection unit, and sets the auxiliary device to a state in which an individual function changed from the basic function is executed according to the connected auxiliary device if the recognition unit recognizes that the auxiliary device is connected to the connection unit.

[0044] As an example, the auxiliary device recognition step S110 may include a step in which the recognition unit recognizes the auxiliary device coupled via wired or wireless communication using the communication module. As another example, the recognition unit may include a sensing module attached to the main body and equipped with a sensor. In this case, the assistive device recognition step S110 may include a step in which the recognition unit recognizes the assistive device by using the sensing module to recognize a recognition object that can be recognized by the sensor attached to the assistive device, and recognizes that assistive devices with different types of recognized objects are different assistive devices.

[0045] The auxiliary device may be a skin guide, a hair guide, a makeup guide, a multi-path guide, or a camera accessory. In this case, the function setting step S120 may include the steps of: if the recognition unit recognizes that a skin guide has been connected to the connecting unit in the auxiliary instrument recognition step S110, the control unit sets a skin printing function according to a preset skin printing algorithm corresponding to the skin guide as an individual function; if the recognition unit recognizes that a hair guide has been connected to the connecting unit in the auxiliary instrument recognition step S110, the control unit sets a hair printing function according to a preset hair printing algorithm corresponding to the hair guide as an individual function; if the recognition unit recognizes that a makeup guide has been connected to the connecting unit in the auxiliary instrument recognition step S110, the control unit sets a makeup printing function according to a preset makeup printing algorithm corresponding to the makeup guide as an individual function; if the recognition unit recognizes that a multi-pass guide has been connected to the connecting unit in the auxiliary instrument recognition step S110, the control unit sets a multi-pass printing function according to a preset multi-pass printing algorithm corresponding to the multi-pass guide as an individual function; and if the recognition unit recognizes that a camera accessory has been connected to the connecting unit in the auxiliary instrument recognition step S110, the control unit sets a camera image printing function according to a preset camera image printing algorithm corresponding to the camera accessory as an individual function.

[0046] In addition, the function setting step S120 may include a step in which, when the recognition unit recognizes that the auxiliary device is connected to the connection unit, the control unit controls the terminal communicatively connected to the printing device to display an interface corresponding to the individual function of the auxiliary device.

[0047] The method for driving a printing apparatus according to the embodiments of the present invention described above may also be embodied in the form of a recording medium containing computer-executable commands, such as program modules, that are executed by a computer. Computer-readable media can be any available media that can be accessed by the computer and includes both volatile and nonvolatile media, and both separate and non-separate media. Note that computer-readable media may include computer storage media, including all volatile and non-volatile, separable and non-separable media embodied in any method or technology for storage of information such as computer-readable commands, data structures, program modules, or other data.
