Description

  The present disclosure relates to a drawing apparatus that performs drawing on a recording medium, and a drawing method used in such a drawing apparatus.

  There are cases in which it is often desirable to rewrite an image on a recording medium that records the image so as to be visible. For example, Patent Documents 1 and 2 disclose a recording medium that can rewrite an image by heat.

  When recording an image on such a recording medium, the drawing apparatus irradiates the recording medium with infrared light in a pattern corresponding to the image to be drawn. Thereby, in the recording layer of the recording medium, the photothermal conversion material absorbs infrared light having a wavelength corresponding to the photothermal conversion material and generates heat. Depending on the heat, the dye is combined with the developer to be in a colored state, or separated from the developer to be in a decolored state. As a result, an image is recorded on the recording medium.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The description will be given in the following order.
1. First Embodiment 2. FIG. Second Embodiment 3. FIG. Third embodiment

<1. First Embodiment>
[Application example]
FIG. 1 shows an example of a house 100 in which the drawing apparatus (drawing apparatus 1) according to the first embodiment is used. In this example, for convenience of explanation, the number of rooms in the house 100 is one. However, the number of rooms is not limited to this, and there may be a plurality of rooms. In this house 100, a security system is introduced. In this security system, for example, a security management unit provided in the console 101 manages the security of the house 100. The security management unit has, for example, two operation modes (a normal mode M1 and a warning mode M2). The normal mode M1 is an operation mode used when the user is in the house 100, and the alert mode M2 is an operation mode used when the user goes out. When going out, the user sets the operation mode to the alert mode M2 using the console 101. Thereby, the security management unit monitors the opening and closing of the door 102 and the window 103, for example. When the security management unit operates in the alert mode M2, if any abnormality occurs in the door 102 or the window 103, the security management unit reports that the abnormality has occurred in the server managed by the security system operating company. It comes to report.

  In this example, the drawing apparatus 1 is installed on the ceiling of the house 100. The drawing apparatus 1 performs drawing on a floor material 90 spread on the floor of the house 100. The drawing apparatus 1 may be detachably installed on the ceiling of the house 100, for example. In this case, for example, you may attach to the ceiling light adapter provided in the ceiling. Moreover, you may install by incorporating in the ceiling of the house 100 (built-in).

  The drawing apparatus 10 irradiates the floor material 90 with infrared light LIR in a pattern corresponding to the image to be drawn. The image to be drawn may be, for example, a single color image or an image having a pattern such as wood grain or marble. Further, it may be a photographic image or an image including characters and symbols.

  FIG. 2 shows a configuration example of the flooring 90. The flooring 90 has a base 91, recording layers 92, 94, 96, heat insulating layers 93, 95, and a protective layer 97. The recording layer 92, the heat insulating layer 93, the recording layer 94, the heat insulating layer 95, the recording layer 96, and the protective layer 97 are formed on the surface of the base 91 in this order.

  The base 91 is a floor base and functions as a substrate for forming each layer on the surface thereof. The color of the surface of the substrate 91 may be white, for example, or a color other than white.

  The recording layers 92, 94, and 96 are capable of reversibly changing the state between the colored state and the decolored state. The recording layers 92, 94, and 96 are configured such that the colors in the colored state are different from each other. Specifically, in this example, the recording layer 92 can develop a magenta color, the recording layer 94 can develop a cyan color, and the recording layer 96 can develop a yellow color. Note that the present invention is not limited to this, and the three recording layers 92, 94, and 96 may correspond to the three colors (magenta, cyan, and yellow). The recording layers 92, 94, and 96 are transparent in the decolored state. Thereby, the flooring 90 can record an image using a color in a wide color gamut.

  Each of the recording layers 92, 94, 96 can be configured to contain, for example, a leuco dye. In this case, each of the recording layers 92, 94, and 96 can be configured to include, for example, a developer, a photothermal conversion material, and a polymer in addition to the leuco dye. The leuco dye is combined with the developer by heat to be in a colored state, or separated from the developer to be in a decolored state. The leuco dyes of the three recording layers 92, 94, and 96 have different colors in the colored state. A photothermal conversion material emits heat by absorbing infrared light. The photothermal conversion materials of the recording layers 92, 94, and 96 have different wavelengths of infrared light to be absorbed. That is, the photothermal conversion material of the recording layer 92 absorbs infrared light with a wavelength λ92, the photothermal conversion material of the recording layer 94 absorbs infrared light with a wavelength λ94, and the photothermal conversion material of the recording layer 96 is red with a wavelength λ96. Absorbs external light.

  The heat insulating layer 93 is for making it difficult for heat to be transmitted between the recording layer 92 and the recording layer 94. The heat insulating layer 95 is for making it difficult for heat to be transmitted between the recording layer 94 and the recording layer 96. The protective layer 97 is for protecting the surface of the flooring 90. The heat insulating layers 93 and 95 and the protective layer 97 are configured using a transparent material.

  With this configuration, an image can be recorded on the flooring 90 so as to be visible. Specifically, the drawing apparatus 10 irradiates the floor material 90 with the infrared light LIR in a pattern corresponding to the image to be drawn. The infrared light LIR includes, for example, an infrared light LIR having a wavelength λ92, an infrared light LIR having a wavelength λ94, and an infrared light LIR having a wavelength λ96. The light intensity of the infrared light LIR of each wavelength is set according to the color of the image to be drawn. In the recording layer 92, the photothermal conversion material absorbs infrared light LIR having a wavelength λ92 and emits heat, and in the recording layer 94, the photothermal conversion material absorbs infrared light LIR having a wavelength λ94 and emits heat. In 96, the photothermal conversion material absorbs infrared light LIR having a wavelength of λ96 and generates heat. In each of the recording layers 92, 94, and 96, the heat generated by the light-to-heat conversion material causes the leuco dye to be combined with the developer to be in a colored state, or separated from the developer to be in a decolored state. . In this way, an image is recorded on the flooring 90 so as to be visible. In addition, the floor material 90 can rewrite the image recorded in such a manner as to be visible.

[Configuration example]
FIG. 3 shows a configuration example of the drawing apparatus 1. The drawing apparatus 1 includes a light irradiation unit 20, a drawing control unit 11, a temperature distribution detection unit 12, a speaker 13, an indicator 14, a storage unit 30, a drawing condition setting unit 15, an image processing unit 16, A communication unit 17 and a control unit 19 are provided.

  The light irradiation unit 20 irradiates the floor material 90 with infrared light LIR. In addition, the light irradiation unit 20 has a function of irradiating the floor material 90 with visible light LV and detecting visible light reflected on the floor material 90. The light irradiation unit 20 includes a light source unit 21, a lens unit 22, a light detection unit 23, and a lens unit 24.

  The light source unit 21 generates light L (infrared light LIR and visible light LV) that is applied to the flooring 90. The light source unit 21 includes, for example, three laser light sources 21IR that generate infrared light and one laser light source 21V that generates visible light. The three laser light sources 21IR are used in both the pre-scanning SC1 and the drawing scanning SC2, which will be described later, and generate infrared light LIRs having different wavelengths. The wavelengths of the infrared light LIR generated by the three laser light sources 21IR correspond to the wavelengths λ92, λ94, and λ96 of the infrared light absorbed by the photothermal conversion materials of the recording layers 92, 94, and 96 of the flooring 90, respectively. . The light intensity of the infrared light LIR generated by the three laser light sources 21IR can be set individually. The laser light source 21V is used in pre-scanning SC1 to be described later, and generates visible light LV having a predetermined wavelength. The light source unit 21 has the lens unit 22 in a state in which the infrared light LIRs having different wavelengths generated by the three laser light sources 21IR and the visible light LV generated by the laser light source 21V are substantially aligned with each other. It radiates | emits toward the flooring 90 via.

  The lens unit 22 guides the light L emitted from the light source unit 21 to the flooring 90. The lens unit 22 is configured by using, for example, one or a plurality of lenses, and the focal length is adjusted based on a control signal supplied from the drawing control unit 11.

  The light detection unit 23 detects visible light reflected by the flooring 90 from the visible light LV emitted from the light source unit 21 in the pre-scanning SC1 described later. The visible light reflected by the flooring 90 is incident on the light detection unit 23 via the lens unit 24.

  The lens unit 24 guides visible light reflected by the flooring 90 to the light detection unit 23. The lens unit 24 is configured using, for example, one or a plurality of lenses, and the focal length is adjusted based on a control signal supplied from the drawing control unit 11.

  With this configuration, the light irradiation unit 20 irradiates the floor material 90 with infrared light LIR. In addition, the light irradiation unit 20 irradiates the floor material 90 with visible light LV and detects visible light reflected on the floor material 90. This light irradiation unit 20 can change the direction of the optical path axis of the light L (infrared light LIR and visible light LV) emitted from the light irradiation unit 20 based on an instruction from the drawing control unit 11. It is configured. Thereby, the light irradiation part 20 can irradiate the light L to the flooring 90, scanning.

  The drawing control unit 11 controls the operation of the light irradiation unit 20 based on an instruction from the control unit 19. Specifically, for example, as illustrated in FIG. 4, the drawing control unit 11 controls the direction of the optical path axis of the light L so that the light irradiation unit 20 irradiates the floor 90 with the light L while scanning. . Further, the drawing control unit 11 controls the light intensity of the infrared light LIR generated by the three laser light sources 21IR included in the light source unit 21, and also controls the light intensity of the visible light LV generated by the laser light source 21V. The drawing control unit 11 also has a function of adjusting the focal lengths of the lens units 22 and 24.

  The temperature distribution detection unit 12 detects a temperature distribution in the flooring 90 and is configured using, for example, an infrared sensor.

  With this configuration, the drawing apparatus 1 performs a scanning operation when performing a drawing operation on the flooring 90. At that time, the drawing apparatus 1 performs two scanning operations (pre-scanning SC1 and drawing scanning SC2). The pre-scan SC1 is performed before actually drawing on the flooring 90, and is performed to set the drawing condition of the infrared light LIR when drawing is performed, as will be described later. . The drawing scan SC2 is for actually drawing on the flooring 90.

  In the pre-scanning SC1, for example, any one of the three laser light sources 21IR of the light source unit 21 irradiates the floor material 90 with infrared light LIR having a light intensity that does not allow drawing, and temperature distribution. The detection unit 12 detects a temperature change of the flooring 90 after the infrared light LIR is irradiated at each coordinate of the flooring 90. For example, the laser light source 21 </ b> V of the light source unit 21 emits visible light LV having a predetermined light intensity, and the light detection unit 23 detects visible light reflected at each coordinate of the flooring 90. The drawing condition setting unit 15 sets the drawing conditions of the infrared light LIR in the drawing scan SC2 based on these detection results, as will be described later.

  In the drawing scan SC2, for example, the three laser light sources 21IR of the light source unit 21 emit infrared light LIR having a light intensity corresponding to the pixel value of the image to be drawn. In this example, the laser light source 21V does not irradiate visible light LV in the drawing scan SC2. Thereby, an image is recorded on the flooring 90.

  The speaker 13 notifies the user of the operating state of the drawing apparatus 1 by sound. Specifically, for example, when the drawing device 1 starts the operation, the speaker 13 notifies by voice that the operation is about to start, and when the drawing device 1 ends the operation, the speaker 13 ends the operation. It may be notified by voice.

  The indicator 14 displays the operation state of the drawing apparatus 1. The indicator 14 is configured using, for example, one or a plurality of LEDs (Light Emitting Diodes). Specifically, when the indicator 14 includes a plurality of LEDs having different colors, for example, during a period in which the drawing apparatus 1 is operating, a certain LED (for example, a yellow LED) is turned on to draw the drawing apparatus 1. May perform other LED (for example, red LED) during the period during which the drawing scan SC2 is performed.

  The storage unit 30 stores image data D to be drawn. The image data D is supplied from the personal computer (not shown) to the drawing apparatus 1 via the communication unit 17 and stored in the storage unit 30, for example.

  The drawing condition setting unit 15 sets drawing conditions for the infrared light LIR in the drawing scan SC2 based on an instruction from the control unit 19. Specifically, the drawing condition setting unit 15 is based on the detection result of the light detection unit 23 in the pre-scanning SC1, and information on the position of an obstacle such as furniture and the surface such as unevenness at each coordinate of the flooring 90. To know the information. In addition, the drawing condition setting unit 15 grasps information about the heat radiation characteristics at each coordinate of the flooring 90 based on the detection result of the temperature distribution detection unit 12 in the pre-scan SC1. In addition, the drawing condition setting unit 15 grasps information about the temperature distribution in the thermal equilibrium state of the flooring 90 based on the detection result of the temperature distribution detection unit 12 after the pre-scan SC1. Then, the drawing condition setting unit 15 sets the drawing conditions of the infrared light LIR in the drawing scan SC2 based on these pieces of information. The drawing conditions include, for example, conditions such as a scanning region when performing the drawing scan SC2, the light intensity of the infrared light LIR, the scanning speed, and the focal length.

  The image processing unit 16 performs predetermined image processing on the image data D stored in the storage unit 30 based on an instruction from the control unit 19. The predetermined image processing includes, for example, processing for enlarging or reducing the image according to the area of the flooring 90, interpolation processing for increasing the definition of the image, and distortion correction processing for reducing distortion caused by irradiating the flooring 90. Etc.

  The communication unit 17 communicates with various electronic devices using a wireless LAN (Local Area Network) based on an instruction from the control unit 19. In this example, the communication unit 17 communicates with the console 101 using a wireless LAN. The communication unit 17 communicates with the console 101 to receive information about the operation mode of the security management unit and the opening / closing of the door 102 and the window 103 from the console 101. Specifically, when the user goes out, when the operation mode is set to the warning mode M2, the console 101 transmits a notification that the operation mode is set to the warning mode M2 to the drawing apparatus 1, and the communication unit 17 receives this notification. For example, when the door 102 or the window 103 is opened, the console 101 transmits a notification that the door 102 or the window 103 is opened to the drawing apparatus 1, and the communication unit 17 receives the notification. Yes.

  Moreover, the communication part 17 communicates with the smart phone 9 via the internet and a mobile telephone network via the router which is not illustrated, for example. The communication unit 17 receives, for example, a drawing operation start instruction or an end instruction from the smartphone 9 by communicating with the smartphone 9. In addition, when the drawing operation in the drawing apparatus 1 is completed, the communication unit 17 transmits a notification that the drawing operation has been completed to the smartphone 9 based on an instruction from the control unit 19. .

  The control unit 19 controls the operation of each block of the drawing apparatus 1. The control unit 19 is configured using, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like.

  With this configuration, for example, the user closes the window 103 of the house 100, sets the operation mode to the alert mode M <b> 2 using the console 101, and confirms that there is no other person in the house 100 before going outside. When exiting and locking the door 102, the console 101 notifies the drawing apparatus 1 that the operation mode is set to the alert mode M2. In the drawing apparatus 1, when the communication unit 17 receives this information, the control unit 19 determines that the house 100 is in a so-called closed room state. When the user operates the smartphone 9 outside the house 100 to give an instruction to start a drawing operation in the drawing apparatus 1, in the drawing apparatus 1, the communication unit 17 receives this start instruction, and the control unit 19 performs the drawing operation. To start. When the communication unit 17 receives a notification that the door 102 or the window 103 is opened from the console 101 during the drawing operation, the control unit 19 stops the drawing operation. When the drawing apparatus 1 performs the pre-scan SC1 and the drawing scan SC2 and ends the drawing operation, the communication unit 17 notifies the smartphone 9 that the drawing operation has ended based on an instruction from the control unit 19.

[Operation and Action]
Next, the operation and action of the drawing apparatus 1 of the present embodiment will be described.

(Overview of overall operation)
First, an overall operation outline of the drawing apparatus 1 will be described with reference to FIG. The drawing apparatus 1 performs a drawing operation when the communication unit 17 receives a drawing operation start instruction from the smartphone 9 when the house 100 is in a closed room. Specifically, first, the drawing apparatus 1 performs pre-scanning SC1. Then, the drawing condition setting unit 15 sets the drawing condition of the infrared light LIR in the drawing scan SC2 based on the result of the pre-scan SC1. The image processing unit 16 performs predetermined image processing on the image data D stored in the storage unit 30. Next, the drawing apparatus 1 performs a drawing scan SC2 using the set drawing conditions based on the image data D on which image processing has been performed. Thereby, an image is recorded on the flooring 90. Then, when the drawing operation of the drawing apparatus 1 ends, the communication unit 17 transmits an operation end notification to the smartphone 9 based on an instruction from the control unit 19.

(Detailed operation)
Next, the detailed operation of the drawing apparatus 1 will be described. The operation of the drawing apparatus 1 when receiving a drawing operation start instruction from the smartphone 9 will be described below.

  FIG. 5 illustrates an operation example of the drawing apparatus 1. When receiving a drawing operation start instruction from the smartphone 9, the drawing apparatus 1 checks whether the house 100 is in a closed room state. If the drawing apparatus 1 is in a closed room state, the drawing apparatus 1 performs pre-scanning SC1, acquires the temperature distribution of the flooring 90, sets drawing conditions, and performs image processing on the image data D. The drawing apparatus 1 performs the drawing scan SC2 using the set drawing conditions based on the image data D on which the image processing has been performed. This operation will be described in detail below.

  When the communication unit 17 receives a drawing operation start instruction from the smartphone 9, the control unit 19 checks whether or not the house 100 is in a closed room state (step S101). Specifically, for example, when the communication unit 17 has already received a notification from the console 101 that the operation mode is set to the alert mode M2, the control unit 19 indicates that the house 100 is in a closed room state. Judge. If the house 100 is not in a closed room state ("N" in step S101), this flow ends.

  In step S101, when the house 100 is in a closed room state ("Y" in step S101), the drawing apparatus 1 performs pre-scanning SC1 (step S102). In the pre-scanning SC1, for example, any one of the three laser light sources 21IR of the light source unit 21 irradiates the infrared light LIR having a low light intensity that does not draw on the flooring 90, and the temperature distribution. The detection unit 12 detects the temperature change of the flooring 90 after the infrared light LIR is irradiated at each coordinate of the flooring 90. For example, the laser light source 21 </ b> V of the light source unit 21 emits visible light LV having a predetermined light intensity, and the light detection unit 23 detects visible light reflected at each coordinate of the flooring 90.

  When the communication unit 17 receives a notification that the door 102 or the window 103 is opened during the pre-scanning SC1, the drawing apparatus 1 performs the operations of all the laser light sources in the light source unit 21. Stop and end this flow.

  FIG. 6 shows the state transition of the light source unit 21. When the drawing apparatus 1 is performing pre-scanning SC1, the state of the light source unit 21 is a light emission state. When this pre-scanning SC1 is completed, the state of the light source unit 21 changes from the light emission state to the light emission stop state. When the communication unit 17 receives a notification that the door 102 or the window 103 is opened from the console 101, the control unit 19 determines that the house 100 is no longer in a closed room state, and the state of the light source unit 21 is the light emission. Transition from the state to the light emission stop state. Then, the flow of FIG. 5 ends. Thereby, in drawing device 1, when a user enters house 100, for example, since a user can reduce a possibility of being exposed to a laser beam, safety can be improved.

  Next, the temperature distribution detector 12 detects the temperature distribution in the thermal equilibrium state of the flooring 90 after the completion of the pre-scanning SC1 (Step S103).

  Next, the drawing condition setting unit 15 sets the drawing conditions of the infrared light LIR in the drawing scan SC2 based on the detection results in steps S102 and S103 (step S104). Specifically, the drawing condition setting unit 15 determines information about the position of an obstacle such as furniture or the coordinates of the flooring 90 based on the detection result of the light detection unit 23 in the pre-scan SC1 (step S102). Grasping surface information such as irregularities. In addition, the drawing condition setting unit 15 grasps information about the heat radiation characteristics at each coordinate of the flooring 90 based on the detection result of the temperature distribution detection unit 12 in the pre-scanning SC1 (Step S102). Further, the drawing condition setting unit 15 grasps information about the temperature distribution in the thermal equilibrium state of the flooring 90 based on the detection result of the temperature distribution detection unit 12 in step S103. The drawing condition setting unit 15 sets drawing conditions (scanning area, light intensity, scanning speed, focal length, etc.) of the infrared light LIR in the drawing scan SC2 based on these pieces of information.

  For example, the drawing condition setting unit 15 sets a scanning area based on information about the position of an obstacle such as furniture. Thereby, the scanning area in the drawing scan SC2 is set to the same area as the scanning area in the pre-scan SC1, or a narrower area included in the scanning area in the pre-scan SC1. In addition, the drawing condition setting unit 15 determines the light intensity of the infrared light LIR, the scanning speed, and the focus at each coordinate of the flooring 90 based on the information on the surface of the flooring 90, the heat radiation characteristics, and the temperature distribution in the thermal equilibrium state. Set the distance. Specifically, for example, the drawing condition setting unit 15 increases the light intensity of the infrared light LIR when the flooring 90 is easy to dissipate heat, and increases the intensity of the infrared light LIR when the flooring 90 is difficult to dissipate. Reduce light intensity. For example, in the thermal equilibrium state, when the temperature of the flooring 90 is low, the light intensity of the infrared light LIR is increased, and when the temperature of the flooring 90 is high, the light intensity of the infrared light LIR is decreased. To do. Instead of increasing the light intensity of the infrared light LIR, the scanning speed may be decreased, or instead of decreasing the light intensity of the infrared light LIR, the scanning speed may be increased.

  Next, the image processing unit 16 performs predetermined image processing on the image data D stored in the storage unit 30 (step S105). Specifically, the image processing unit 16 performs, for example, processing for enlarging or reducing an image according to the area of the flooring 90, interpolation processing for increasing the definition of the image, and distortion caused by irradiating the flooring 90. Perform distortion correction processing to reduce.

  Next, the drawing apparatus 1 performs a drawing scan SC2 (step S106). In the drawing scan SC2, the three laser light sources 21IR of the light source unit 21 use the drawing conditions set in step S104 and based on the image subjected to image processing in step S105, according to the pixel value of the image. Infrared light LIR having a high light intensity is generated.

  During the period during which the drawing scan SC2 is performed, when the communication unit 17 receives a notification that the door 102 or the window 103 is opened, or the temperature distribution detection unit 12 has an abnormal temperature of the flooring 90. Is detected, the drawing apparatus 1 stops the operations of all the laser light sources in the light source unit 21, and the flow ends.

  FIG. 7 shows the state transition of the light source unit 21. When the drawing apparatus 1 performs the drawing scan SC2, the state of the light source unit 21 is a light emission state. When the drawing scan SC2 ends, the state of the light source unit 21 changes from the light emission state to the light emission stop state. When the communication unit 17 receives a notification from the console 101 that the door 102 or the window 103 has been opened, the control unit 19 determines that the house 100 is no longer in a closed room state, and the state of the light source unit 21 Transitions from the light emitting state to the light emission stopped state. Then, the flow of FIG. 5 ends. Thereby, in drawing device 1, when a user enters house 100, for example, since a user can reduce a possibility of being exposed to a laser beam, safety can be improved. When the temperature distribution detection unit 12 detects that the temperature of the flooring 90 is higher than a predetermined threshold temperature or the like, the control unit 19 has detected an abnormality in the drawing operation. And the state of the light source unit 21 transitions from the light emission state to the light emission stop state. Then, the flow of FIG. 5 ends. Thereby, in the drawing apparatus 1, since it can suppress that the temperature of the flooring 90 becomes unnecessarily high, safety can be improved.

  In this way, the drawing apparatus 1 performs the drawing scan SC2. When the drawing scan SC2 is completed, an image is recorded on the flooring 90.

  Next, the temperature distribution detection unit 12 checks whether or not the temperature of the flooring 90 is sufficiently low (step S107). Specifically, the temperature distribution detection unit 12 detects the temperature distribution of the flooring 90 and confirms whether or not the temperature of the flooring 90 is sufficiently lowered to the extent that the user can enter the house 100. To do. If the temperature of the flooring 90 is still high (“N” in step S107), the process returns to step S107, and this step S107 is repeated until the temperature of the flooring 90 is sufficiently lowered.

  In step S107, when the temperature of the flooring 90 is sufficiently low (“Y” in step S107), the communication unit 17 notifies the smartphone that the drawing operation has ended based on an instruction from the control unit 19. 9 (step S108). Thereby, the user knows that drawing on the flooring 90 has been completed.

  This flow is completed.

  As described above, the drawing apparatus 1 performs the pre-scan SC1, sets the drawing conditions of the infrared light LIR in the drawing scan SC2 based on the result of the pre-scan SC1, and performs the drawing scan SC2 using the drawing conditions. I made it. Thereby, in the drawing apparatus 1, since drawing conditions can be adjusted according to the characteristic peculiar to the house 100, such as the arrangement condition of the obstacle, the information on the surface of the flooring 90, and the heat radiation characteristic, the image quality is improved. be able to.

  Further, the drawing apparatus 1 starts the drawing operation when the house 100 is in a closed room state, and stops the drawing operation when the house 100 is not in the closed room state after starting the drawing operation. Thereby, in drawing device 1, since a drawing operation is not started, for example, when a user is in house 100, a user can reduce a possibility of being exposed to a laser beam. In addition, for example, when the user accidentally enters the house 100 after starting the drawing operation, the drawing operation is stopped, so that the user can be exposed to the laser light. As a result, the drawing apparatus 1 can improve safety.

  In the drawing apparatus 1, since the temperature distribution detection unit 12 monitors the temperature of the flooring 90 in the drawing scanning SC <b> 2, the temperature of the flooring 90 can be suppressed from becoming higher than necessary. , Can increase safety.

[effect]
As described above, in the present embodiment, pre-scanning is performed, and the drawing condition of the infrared light in the drawing scanning is set based on the result of the pre-scanning, so that the image quality can be improved.

  In this embodiment, the drawing operation is started when the house is in a closed room, and the drawing operation is stopped when the house is not in the closed room after starting the drawing operation. Can be increased.

  Further, in the present embodiment, the temperature of the flooring material is monitored during the drawing scan, so that safety can be improved.

[Modification 1-1]
In the above embodiment, the drawing apparatus 1 operates in cooperation with the security system, but the present invention is not limited to this. Instead, for example, in a house where a security system is not introduced, sensors for detecting opening and closing may be provided on the door 102 and the window 103, and these sensors may supply the detection result to the drawing apparatus 1. In this case, when the drawing apparatus 1 receives a drawing operation start instruction from the smartphone 9, the control unit 19 has already received a notification that the door 102 and the window 103 are closed from these sensors. If it is, the house 100 is determined to be in a closed room state, and the drawing apparatus 1 starts the drawing operation. Further, for example, in the pre-scan SC1 and the drawing scan SC2, the control unit 19 determines that the house 100 is in a closed room state when the communication unit 17 receives a notification that the door 102 or the window 103 is opened from these sensors. Therefore, the operation of all the laser light sources is stopped.

  In particular, when there are a plurality of rooms in the house 100, such a sensor can be provided on a door or window of a room where drawing is performed. In this case, when the drawing apparatus 1 performs the drawing operation, the user does not necessarily have to go out and may be in a room other than the room where the drawing is performed.

  In this example, the door 102 and the window 103 are provided with sensors for detecting opening and closing, but the present invention is not limited to this. Instead, for example, an imaging unit configured to include a camera or the like may be provided in the drawing apparatus, and opening / closing of a door or a window may be detected based on the captured image.

[Modification 1-2]
In the above-described embodiment, the heat radiation characteristics at each coordinate of the flooring 90 are obtained by performing the pre-scanning SC1, but the present invention is not limited to this. Instead of this, for example, the heat dissipation characteristics at one or more representative points of the flooring 90 may be obtained. That is, when the heat dissipation characteristics do not change so much depending on the coordinates of the flooring 90, the heat dissipation characteristics can be acquired only for one or a plurality of representative points as described above. Below, the drawing apparatus 1B which concerns on this modification is demonstrated.

  FIG. 8 illustrates an operation example of the drawing apparatus 1B. The drawing apparatus 1B obtains heat dissipation characteristics at a plurality of representative points. In this example, in step S112 (pre-scanning SC1), the laser light source 21V of the light source unit 21 emits visible light LV having a predetermined light intensity, and the light detection unit 23 is reflected at each coordinate of the flooring 90. Detect visible light. That is, unlike the case of the above-described embodiment, the drawing apparatus 1B does not perform irradiation with the infrared light LIR and detection of a temperature change of the flooring 90. Then, after this pre-scanning SC1, the drawing apparatus 1B acquires heat dissipation characteristics at a plurality of representative points of the flooring 90 (step S113). Specifically, for example, the light source unit 21 generates infrared light LIR having low light intensity that does not draw on the flooring 90, and sequentially irradiates the infrared light LIR to a plurality of representative points. The temperature distribution detection unit 12 detects a temperature change of the flooring 90 at each of the plurality of representative points. And the drawing condition setting part 15 calculates | requires the thermal radiation characteristic of the flooring 90 based on the detection result.

[Modification 1-3]
In the above embodiment, the drawing scan SC2 is performed after the prescan SC1 is performed, but the present invention is not limited to this. If an image has already been recorded on the flooring 90, the drawing scan SC2 may be performed after the image is once erased. Hereinafter, a drawing apparatus 1C according to the present modification will be described.

  FIG. 9 illustrates an operation example of the drawing apparatus 1C. In this example, after the drawing condition setting unit 15 sets drawing conditions in step S104, the drawing apparatus 1C performs erasure scanning SC3 using the drawing conditions (step S114). In the erasing scan SC3, for example, the three laser light sources 21IR of the light source unit 21 generate infrared light LIR having such a light intensity that the image can be erased. Thereafter, the image processing unit 16 performs image processing (step S105), and the drawing apparatus 1C performs drawing scanning SC2 (step S106).

[Modification 1-4]
In the above embodiment, the drawing apparatus 1 performs drawing on the flooring 90, but is not limited to this. Instead, for example, drawing may be performed on the wallpaper 80 already stretched on the wall of the house 100D as in the drawing device 1D shown in FIG. This wallpaper 80 has the same configuration as the flooring 90 (FIG. 2) of the above embodiment, for example.

[Other variations]
Further, two or more of these modifications may be combined.

<2. Second Embodiment>
Next, the drawing apparatus 2 according to the second embodiment will be described. This embodiment is different from the first embodiment in a method for improving safety. That is, in the first embodiment, the drawing operation is controlled based on whether or not the house 100 is in a closed room state. Instead, in the present embodiment, a living body detection unit is added to the drawing apparatus 2.

This guide G shows the position where the light source unit 21 irradiates the infrared light LIR.

  FIG. 12 shows an example of the guide G displayed on the surface of the flooring 90. In this example, the position where the light source unit 21 irradiates the infrared light LIR is moved from left to right by the drawing device 2 performing a scanning operation. The irradiation position P is irradiated with infrared light LIR, and the guide G is displayed so as to be visible with visible light so as to surround the irradiation position P.

Accordingly, the user can easily grasp where the infrared light LIR is irradiated on the flooring 90.

  The light irradiation unit 50 includes a guide light source 51 and a lens unit 52. The guide light source 51 generates guide light LG. The guide light source 51 includes, for example, a laser light source 51G that generates visible light. The laser light source 51G is used, for example, in the pre-scan SC1 and the drawing scan SC2. The lens unit 52 guides the guide light LG emitted from the guide light source 51 to the flooring 90. The lens unit 52 is configured using, for example, one or a plurality of lenses, and the focal length is adjusted based on a control signal supplied from the drawing control unit 41.

  The drawing control unit 41 controls the operation of the light irradiation unit 50 based on an instruction from the control unit 49.

The direction of the optical path axis of L is controlled. The drawing control unit 41 controls the light intensity of the infrared light LIR generated by the light source unit 21, controls the light intensity of the visible light LV generated by the light source unit 21, and guide light generated by the guide light source 51. The light intensity of LG is controlled. The drawing control unit 41 also has a function of adjusting the focal lengths of the lens units 22, 24, and 52.

  The living body detection unit 42 detects a living body such as a human being or an animal in the house 100 based on an instruction from the control unit 49. In this example, the living body detection unit 42 analyzes the shape indicated by the temperature distribution and the movement of the shape based on the map data of the temperature distribution detected by the temperature distribution detection unit 12, and based on the analysis result. The presence or absence of a living body is detected.

  The control unit 49 controls the operation of each block of the drawing apparatus 2.

  With this configuration, for example, when the user goes out after confirming that there is no one in the house 100, the living body detection unit 42 detects that there is no living body in the house 100. When the user operates the smartphone 9 outside the house 100 to give a drawing operation start instruction in the drawing apparatus 2, in the drawing apparatus 2, the communication unit 17 receives this start instruction, and the control unit 49 draws. Start operation. When the living body detection unit 42 detects a living body in the house 100 during the drawing operation, the control unit 49 stops the drawing operation. Then, when the drawing apparatus 2 performs the pre-scan SC1 and the drawing scan SC2 and ends the drawing operation, the communication unit 17 notifies the smartphone 9 that the drawing operation has ended based on an instruction from the control unit 49. It comes to notify.

  FIG. 13 illustrates an operation example of the drawing apparatus 2. When receiving the drawing operation start instruction from the smartphone 9, the drawing apparatus 2 confirms the presence or absence of a living body in the house 100. If a living body is not detected in the house 100, the drawing apparatus 2 performs pre-scanning SC1, acquires the temperature distribution of the flooring 90, sets drawing conditions, and performs image processing on the image data D.

Specifically, for example, as shown in FIG. 18, the wheel drive unit 63 drives the wheel unit 62 so that the light irradiation unit 70 irradiates the floor 90 with the light L while scanning. .

  The light irradiation unit 70 irradiates the floor material 90 with the infrared light LIR, similarly to the light irradiation unit 20 according to the first embodiment. The light irradiation unit 70 also has a function of irradiating the floor material 90 with visible light LV and detecting visible light reflected by the floor material 90. The light irradiation unit 70 is disposed on the bottom surface of the drawing apparatus 3. And the light irradiation part 70 irradiates the flooring 90 with the light L, as the drawing apparatus 3 moves using the wheel part 62, scanning.

  The drawing control unit 61 controls the operations of the light irradiation unit 70 and the wheel driving unit 63 based on an instruction from the control unit 69. Specifically, the drawing control unit 61 controls the operation of the wheel driving unit 63 so that the light irradiating unit 70 irradiates the floor 90 with the light L while scanning. Further, the drawing control unit 61 controls the light intensity of the infrared light LIR generated by the three laser light sources 21IR included in the light source unit 21, and controls the light intensity of the visible light LV generated by the laser light source 21V. The drawing control unit 61 also has a function of adjusting the focal lengths of the lens units 22 and 24.

  The temperature detection unit 64 is disposed on the bottom surface of the drawing apparatus 3 and detects the temperature of the flooring 90 in the lower part of the drawing apparatus 3.

  The temperature distribution detector 65 detects the temperature distribution in the flooring 90. The temperature distribution detection unit 65 is configured using, for example, a plurality of infrared sensors arranged on the side surface around the drawing apparatus 3. Thereby, the temperature distribution detector 65 can detect the temperature distribution of the flooring 90 in a wide range around the drawing device 3.

  In step S301, when the drawing apparatus 3 is not tilted (“Y” in step S301), the drawing apparatus 3 performs pre-scanning SC1 (step S302). In this pre-scan SC1, for example, any one of the three laser light sources 21IR of the light source unit 21 irradiates the infrared light LIR having a light intensity that does not allow the flooring 90 to be drawn, and detects the temperature. The unit 64 detects the temperature change of the flooring 90 after the infrared light LIR is irradiated at each coordinate of the flooring 90. Further, for example, the laser light source 21 </ b> V of the light source unit 21 emits visible light LV having a predetermined light intensity, and the light detection unit 23 detects visible light reflected at each coordinate of the flooring 90.

  When the tilt sensor 66 detects that the drawing device 3 is tilted during the period of the pre-scanning SC1, the drawing device 3 detects all of the light sources 21 as shown in FIG. The operation of the laser light source is stopped, and this flow ends.

Predetermined image processing is performed on the data D (step S305).

  Next, the drawing apparatus 2 performs the drawing scan SC2 similarly to the drawing apparatus 1 according to the first embodiment (step S306).

  In the period during which the drawing scan SC2 is performed, when the inclination sensor 66 detects that the drawing apparatus 3 is inclined, the temperature detector 64 or the temperature distribution detector 65 detects that the temperature of the flooring 90 is abnormal. When it is detected that there is, the drawing apparatus 3 stops the operation of all the laser light sources in the light source unit 21 as shown in FIG. 21, and this flow ends.

  When the drawing scan SC2 is completed, an image is recorded on the flooring 90.

  Next, as in the case of the first embodiment, the temperature distribution detection unit 65 checks whether or not the temperature of the flooring 90 is sufficiently low (step S307), and the temperature of the flooring 90 is sufficient. The communication unit 17 transmits a notification that the drawing operation has ended to the smartphone 9 based on an instruction from the control unit 69 (step S308).

  This flow is completed.

  As described above, since the drawing apparatus 3 performs drawing on the flooring material 90 while traveling on the flooring material 90, the laser light emitted from the drawing device 3 immediately reaches the flooring material 90. Even when the user is in the room of the house 110, the risk of the user being exposed to the laser beam can be reduced. As a result, the drawing device 3 can improve safety.

  In the drawing apparatus 3, the inclination sensor 66 is provided, and the inclination sensor 66 detects the inclination of the drawing apparatus 3. For example, when the user accidentally lifts the drawing apparatus 3, the user uses the laser beam. Therefore, safety can be improved.
