FIG. 8 is a diagram showing an example of the target sample image A31 and the sample image A32. In the present embodiment, as shown in FIG. 8, the acute-angled portion P1 of the target sample image A31 indicates the direction of the tip of the ear 8b. Here, the acute-angled portion P1 is oriented so as to be pointed toward the left rear, and the direction of the acute-angled portion P1 is the setting direction D1 at the tip of the ear 8b. In the present embodiment, the thickness L1 of the target sample image A31 indicates the set thickness of the spike 8b. This set thickness L1 is the length of the target sample image A31 in the direction in which the acute-angled portion P1 is sandwiched. The setting direction D1 and the setting thickness L1 of the target sample image A31 are stored in advance in the storage unit 61.

Further, as shown in FIG. 6, the target sample image A31 may or may not be drawn in the test drawing area R2 of the medium 5. The target sample image A31 may be printed on the test drawing area R2 by the ink head 22. In this case, the target sample image A31 may be printed at the time of printing the printed image A1 in step S1 of FIG. 7.

In the present embodiment, in step S2, as shown in FIG. 6, the sample image A32 is drawn with the brush 8 in the test drawing area R2 of the medium 5. By comparing this sample image A32 with the target sample image A31 and adjusting the thickness of the ear 8b of the brush 8 and the direction of the tip of the ear 8b, the brush 8 is adjusted according to the start position of the brush drawing image A2. The thickness of the spike 8b can be made appropriate, and the tip of the spike 8b can be oriented appropriately.

In the present embodiment, as shown in FIG. 7, the process of step S2 is performed by sequentially executing the processes of steps S201 to S210. First, in step S201, the trial drawing start moving unit 71 controls the medium moving mechanism 50 and the carriage moving mechanism 40 so that the spike 8b of the brush 8 is located above the trial drawing area R2 of the medium 5. By the process of step S201, the spike 8b of the brush 8 supported by the holder 32 is located directly above the trial drawing region R2 of the medium 5, and the spike 8b extends toward the trial drawing region R2.

In step S201, the medium moving mechanism 50 and the carriage moving mechanism 40 control the trial drawing start moving unit 71 so that the brush 8 is not arranged above the area in the trial drawing area R2 where the image is already formed. It should be done. In other words, when an image is already formed in the trial drawing area R2, the trial drawing start moving unit 71 does not arrange the brush 8 at the position where the trial image A32 is drawn on the already formed image. It controls the medium moving mechanism 50 and the carriage moving mechanism 40.

In the state where the ear 8b is located above the trial drawing area R2 in this way, in step S202, the trial drawing control unit 72 performs trial drawing. Here, the trial drawing control unit 72 controls the pressurizing mechanism 45 so that the spike 8b of the brush 8 comes into contact with the medium 5. Here, the trial drawing control unit 72 moves the brush 8 downward to bring the ear 8b into contact with the trial drawing area R2 of the medium 5, so that the sample image A32 is brought into the trial drawing area R2 as shown in FIG. draw.

Next, in step S203 of FIG. 7, the trial drawing detection unit 73 detects the sample image A32 drawn in the trial drawing area R2 by the sensor 34 (see FIG. 4). Here, the trial drawing detection unit 73 controls the medium movement mechanism 50 and the carriage movement mechanism 40 to control the main scanning direction Y and the sub-scanning direction X of the sensor 34 with respect to the sample image A32 drawn in the trial drawing area R2. The position is changed. As a result, the sensor 34 can scan on the sample image A32 and detect the sample image A32. Information about the sample image A32 detected by the sensor 34 is transmitted to the control device 60 and stored in the storage unit 61.

Next, in step S204 of FIG. 7, the actual thickness calculation unit 74 calculates the actual thickness L2 (see FIG. 8), which is the actual thickness of the ear 8b, from the sample image A32 detected by the sensor 34. The actual thickness L2 here is the length of the sample image A32 at the position corresponding to the set thickness L1 of the target sample image A31 described above. Here, the actual thickness L2 of the ear 8b is calculated from the sample image A32 by performing image processing on the sample image A32. The actual thickness L2 of the ear 8b calculated by the actual thickness calculation unit 74 is stored in the storage unit 61.

Next, in step S205 of FIG. 7, the thickness determination unit 75 has the actual thickness L2 of the ear 8b calculated by the actual thickness calculation unit 74 and the set thickness L1 of the target sample image A31 (see FIG. 8). It is determined whether or not the difference from the above is equal to or less than a predetermined threshold value. Here, the difference between the actual thickness L2 and the set thickness L1 is an example of the thickness difference of the present invention. The threshold value is stored in the storage unit 61 in advance and is set according to the brush drawing image A2. However, this threshold value may be a fixed numerical value.

In step S205, when the difference between the actual thickness L2 of the ear 8b and the set thickness L1 (in other words, the thickness difference) is larger than the threshold value by the thickness determination unit 75, the thickness of the ear 8b is not appropriate. It is determined that there is no such thing. In this case, the next step is step S206.

In step S206, the operation amount calculation unit 76 calculates the operation amount of the ear adjusting member 33 based on the actual thickness L2 and the set thickness L1. In the present embodiment, the operating amount of the ear adjusting member 33 is the amount of rotation of the ear adjusting member 33. Here, the length at which the spike 8b can be pushed downward is predetermined according to the amount of rotation of the spike adjusting member 33. Further, the thickness of the ear 8b is determined according to the length of the ear 8b. Therefore, the thickness of the panicle 8b can be adjusted by calculating the difference between the actual thickness L2 and the set thickness L1 and determining the amount of operation of the panicle adjusting member 33 for the difference.

Next, in step S207 of FIG. 7, the display unit 77 notifies the user of the operation amount of the ear adjusting member 33 calculated in step S206. Here, the display unit 77 displays the operation amount of the ear adjusting member 33 on the display screen 12a (see FIG. 1) of the operation panel 12. The user of the brush drawing device 100 rotates the ear adjusting member 33 with respect to the holder 32 by the amount of operation of the ear adjusting member 33 displayed on the display screen 12a. As a result, the difference between the actual thickness L2 and the set thickness L1 becomes close to 0, and the thickness of the ear 8b becomes an appropriate thickness. After the operation of the ear adjusting member 33 is completed by the user, the process returns to step S201 again as shown in FIG. 7.

In step S205, when the thickness determination unit 75 determines that the difference between the actual thickness L2 of the ear 8b and the set thickness L1 is equal to or less than the threshold value, the thickness of the ear 8b is an appropriate thickness. Is determined. In this case, the next step is step S208.

Next, in step S208, the actual orientation acquisition unit 81 acquires the actual orientation D2 (see FIG. 8), which is the actual orientation of the tip of the ear 8b, from the sample image A32 detected by the trial drawing detection unit 73. Here, the sample image A32 has an acute-angled portion P1 as in the target sample image A31. The actual orientation acquisition unit 81 determines the actual orientation D2 at the tip of the ear 8b according to the sharp direction of the acute-angled portion P1. In the sample image A32 shown in FIG. 8, the acute-angled portion P1 faces to the right.

Next, in step S209, the orientation determination unit 82 determines whether or not the actual orientation D2 at the tip of the ear 8b is the setting orientation D1 of the target sample image A31. Here, for example, the actual orientation D2 and the setting orientation D1 can be quantified using a predetermined formula or the like. The orientation determination unit 82 determines whether or not the difference between the digitized actual orientation D2 and the digitized setting orientation D1 is equal to or less than a predetermined orientation threshold stored in the storage unit 61, thereby determining the actual orientation. It is determined whether or not D2 is in the setting direction D1. Here, the orientation determination unit 82 determines that the actual orientation D2 is the setting orientation D1 when, for example, the difference between the digitized actual orientation D2 and the digitized setting orientation D1 is equal to or less than the orientation threshold value. On the other hand, the orientation determination unit 82 determines that the actual orientation D2 is not the setting orientation D1 when the difference between the digitized actual orientation D2 and the digitized setting orientation D1 is larger than the orientation threshold value.

In step S209 of FIG. 7, when the orientation determination unit 82 determines that the actual orientation D2 at the tip of the ear 8b is not the setting orientation D1, the next step is step S210. In step S210, the orientation determination unit 83 controls the medium moving mechanism 50 and the carriage moving mechanism 40 in a state where the ear 8b is in contact with the medium 5 so that the actual direction D2 at the tip of the ear 8b becomes the setting direction D1. .. As a result, the ear 8b moves in contact with the medium 5, so that the direction of the tip of the ear 8b is changed. Here, in a state where the ear 8b is in contact with the medium 5, for example, the brush 8 moves to the right with respect to the medium 5, so that the tip of the ear 8b is oriented to the left. In the case of FIG. 8, the setting direction D1 of the ear 8b is the left rear direction. Therefore, in the case of FIG. 8, the orientation determination unit 83 moves the brush 8 forward to the right with respect to the medium 5 in a state where the ear 8b is in contact with the medium 5. As a result, the actual orientation D2 of the ear 8b becomes the setting orientation D1. In this way, after the orientation determination unit 83 changes the actual orientation D2 of the ear 8b, the process returns to step S201 again as shown in FIG. 7.

In step S209, when the orientation determination unit 82 determines that the actual orientation D2 is the set orientation D1, it means that the orientation of the tip of the ear 8b is determined to be an appropriate orientation. As a result, the thickness of the ear 8b becomes an appropriate thickness, and the direction of the tip of the ear 8b becomes an appropriate direction. In this case, the process of step S2 is completed, and then the process proceeds to step S3.

In step S3, the main drawing control unit 85 performs the main drawing based on the image data DT1. In the present embodiment, as shown in FIG. 6, the drawing control unit 85 draws the brush drawing image A2 of the image data DT1 with the brush 8 in the image area R1 of the medium 5 supported by the platen 16. Here, the drawing control unit 85 controls the medium moving mechanism 50 and the carriage moving mechanism 40 in a state where the ear 8b of the brush 8 is in contact with the medium 5 according to the brush drawing image A2. As a result, the positions of the main scanning direction Y and the sub-scanning direction X of the brush 8 with respect to the medium 5 are changed, so that the brush drawing image A2 is drawn in the image area R1. In this embodiment, the brush drawing image A2 may be drawn on the print image A1.

By controlling the pressurizing mechanism 45, the drawing control unit 85 changes the pressure of the brush 8 on the medium 5 (in other words, the writing pressure), and changes the position of the brush 8 in the vertical direction Z. By changing the position of the brush 8 in the vertical direction Z with respect to the medium 5, the thickness of the spike 8b in contact with the medium 5 can be changed. For example, when expressing the character "payment" with the brush 8, the brush 8 is gradually moved upward with respect to the medium 5 while changing the positions of the main scanning direction Y and the sub-scanning direction X of the brush 8 with respect to the medium 5. It is good to let it. When expressing the "stop" of a character with the brush 8, after changing the positions of the main scanning direction Y and the sub-scanning direction X of the brush 8 with respect to the medium 5, the positions of the main scanning direction Y and the sub-scanning direction X of the brush 8 Move the brush 8 upward without changing. As a result, the ear 8b of the brush 8 is separated from the medium 5 upward, so that a "stop" can be expressed. As described above, the drawing control unit 85 appropriately changes the positions of the main scanning direction Y, the sub-scanning direction X, and the vertical direction Z of the brush 8 with respect to the medium 5, so that the drawing image is drawn in the image area R1 of the medium 5. A2 can be drawn.

As described above, in the present embodiment, as shown in FIG. 1, the brush drawing device 100 includes a platen 16 on which the medium 5 is supported and a guide rail 17 arranged above the platen 16 and extending in the main scanning direction Y. A brush carriage 31 that is slidably engaged with the guide rail 17 and a holder 32 that is provided on the brush carriage 31 and supports the brush 8 above the platen 16 are provided. The brush drawing device 100 further moves the carriage moving mechanism 40 (see FIG. 3A) that moves the brush carriage 31 in the main scanning direction Y, and the medium 5 supported by the platen 16 with respect to the brush carriage 31 in the sub-scanning direction X. It is provided with a medium moving mechanism 50 for moving the carriage to the carriage 50 and a pressurizing mechanism 45 (see FIG. 4) for changing the pressure of the brush 8 supported by the holder 32 with respect to the medium 5 supported by the platen 16.

As a result, the brush 8 is used to bring the spike 8b of the brush 8 into contact with the medium 5 supported by the platen 16, and the main scanning direction Y, the sub-scanning direction X, and the vertical direction of the medium 5 and the brush 8 By changing the relative position of Z, it is possible to produce a brush drawing image A2 (see FIG. 6) that reproduces the unique expression of the brush 8 (for example, blurring, shading, etc.). Therefore, the image can be drawn by reproducing the unique expression of the brush 8.

In the present embodiment, as shown in FIG. 4, the brush 8 has a shaft tube 8a and a spike 8b which is a bundle of hairs provided at one end of the shaft tube 8a. The ear adjusting member 33 adjusts the length of the ear 8b provided on the holder 32 and located below the holder 32. As a result, the length of the ear 8b located below the holder 32 can be adjusted by operating the ear adjusting member 33. With the brush 8, the thickness of the ear b is also changed according to the length of the ear 8b. Therefore, the thickness of the ear 8b can be adjusted by operating the ear adjusting member 33. Therefore, an image can be drawn on the medium 5 with various thicknesses of the spikes 8b.

In the present embodiment, the ear adjusting member 33 is a ring-shaped member into which the brush 8 is inserted, and is rotatable with respect to the holder 32. The ear adjusting member 33 is configured to change the length of the ear 8b located below the holder 32 by rotating with respect to the holder 32. In this way, the length of the spike 8b of the brush 8 can be adjusted by a simple method of rotating the spike adjusting member 33 with respect to the holder 32.

In the present embodiment, as shown in FIG. 6, the medium 5 is an image area R1 in which the main drawing, which is the drawing of the brush 8 based on the predetermined image data DT1, is performed, and an area other than the image area R1. It has a trial drawing area R2 on which a trial drawing before the main drawing is performed. The sensor 34 detects the sample image A32 drawn by the test drawing drawn on the medium 5. The trial drawing start moving unit 71 of the control device 60 controls at least the carriage moving mechanism 40 so that the spike 8b of the brush 8 is located above the trial drawing area R2 of the medium 5 supported by the platen 16. The trial drawing control unit 72 controls the pressurizing mechanism 45 so that the spikes 8b are brought into contact with the medium 5 to draw the preview image A32 while the spikes 8b are located above the trial drawing region R2. The trial drawing detection unit 73 detects the sample image A32 drawn by the trial drawing control unit 72 with the sensor 34. The actual thickness calculation unit 74 calculates the actual thickness L2 (see FIG. 8), which is the actual thickness of the spikes 8b, from the sample image A32 detected by the trial drawing detection unit 73. The thickness determination unit 75 determines whether or not the thickness difference, which is the difference between the actual thickness L2 and the preset thickness L1 (see FIG. 8), which is the thickness of the ear 8b, is equal to or less than a predetermined threshold value. To judge. When the thickness determination unit 75 determines that the thickness difference is larger than the threshold value, the operation amount calculation unit 76 calculates the operation amount of the ear adjusting member 33 based on the actual thickness L2 and the set thickness L1. To do.

As a result, when the thickness difference, which is the difference between the actual thickness L2 and the set thickness L1, is larger than the threshold value, the actual thickness L2 of the ear 8b is not the set thickness L1 but an appropriate thickness. Absent. In this case, the user operates the ear adjusting member 33 by the amount of the operation amount of the ear adjusting member 33 calculated by the operation amount calculation unit 76, so that the actual thickness L2 of the ear 8b is changed to the set thickness L1. It can be made close in thickness.

In the present embodiment, the display unit 77 displays the operation amount of the ear adjusting member 33 calculated by the operation amount calculation unit 76 on the display screen 12a (see FIG. 1) of the operation panel 12. As a result, the operating amount of the ear adjusting member 33 is displayed on the display screen 12a, so that it is easy to confirm the operating amount of the ear adjusting member 33. Therefore, the ear adjusting member 33 can be operated while checking the operation amount of the ear adjusting member 33 displayed on the display screen 12a.

In the present embodiment, the actual orientation acquisition unit 81 acquires the actual orientation D2 (see FIG. 8), which is the actual orientation of the ear 8b, from the sample image A32 detected by the trial drawing detection unit 73. The orientation determination unit 82 determines whether or not the actual orientation D2 is the setting orientation D1 (see FIG. 8), which is the preset orientation of the ear 8b. When the orientation determination unit 82 determines that the actual orientation D2 is not the setting orientation D1, the orientation determination unit 83 is in a state where the spikes 8b are in contact with the medium 5 so that the actual orientation D2 is in the setting orientation D1. It controls the carriage moving mechanism 40 and the medium moving mechanism 50. As a result, the actual orientation D2 of the ear 8b can be easily changed by moving the brush 8 in the main scanning direction Y and the sub-scanning direction X with respect to the medium 5 in the state where the ear 8b is in contact with the medium 5. be able to.

In the present embodiment, the drawing control unit 85 determines that the thickness difference is equal to or less than the threshold value by the thickness determination unit 75, and the orientation determination unit 82 determines that the actual orientation D2 is the setting orientation D1. At this time, the main drawing is performed based on the image data DT1. As described above, the main drawing is performed when the thickness of the ear 8b is an appropriate thickness and the direction of the tip of the ear 8b is an appropriate direction. Therefore, it is easy to perform drawing that faithfully reproduces the image of the image data DT1.

In this embodiment, as shown in FIG. 3A, the ink carriage 21 is slidably engaged with the guide rail 17. The ink head 22 has a nozzle for ejecting ink and is provided on the ink carriage 21. As a result, printing can be performed on the medium 5 by ejecting ink from the ink head 22. Therefore, one device can print with the ink head 22 and draw with the brush 8.

In the present embodiment, the image data DT1 (see FIG. 6) is stored in the storage unit 61. As shown in FIG. 6, the image data DT1 has a printed image A1 formed of ink ejected from the ink head 22 and a brush drawn image A2 drawn by a brush 8 supported by a holder 32. Based on the image data DT1, the drawing control unit 85 draws the brush drawing image A2 on the medium 5 with the brush 8 supported by the holder 32. The print control unit 63 ejects ink from the ink head 22 based on the image data DT1 to print the print image A1 on the medium 5. As a result, using one image data DT1, both printing by the ink head 22 and drawing by the brush 8 supported by the holder 32 can be performed.

In the present embodiment, an image is formed on the medium 5 in the order of printing by the ink head 22 (step S1), trial drawing by the brush 8 (step S2), and main drawing by the brush 8 (step S3). However, the order of processing is not particularly limited. For example, after the main drawing by the brush 8 (step S3), printing by the ink head 22 (step S1) may be performed.

In the present embodiment, as shown in FIG. 3A, the carriage moving mechanism 40 moves the brush carriage 31 in the main scanning direction Y. The ink carriage 21 and the brush carriage 31 were connected by connecting members 39a and 39b composed of magnets. For example, at the time of drawing with the brush 8, only the brush carriage 31 moved in the main scanning direction Y in a state where the connection between the ink carriage 21 and the brush carriage 31 by the connecting members 39a and 39b was released. For example, at the time of printing, the ink carriage 21 and the brush carriage 31 were moved in the main scanning direction Y together with the brush carriage 31 in a state where the ink carriage 21 and the brush carriage 31 were connected.

However, the configuration for moving the ink carriage 21 and the brush carriage 31 in the main scanning direction Y is not particularly limited. For example, a connecting carriage engaged with the guide rail 17 may be provided between the ink carriage 21 and the brush carriage 31. The connected carriage is configured to move in the main scanning direction Y by the carriage moving mechanism 40, and is configured to be selectively connectable to the ink carriage 21 and the brush carriage 31. In this case, for example, at the time of drawing with a brush, the brush carriage 31 is moved in the main scanning direction Y together with the connected carriage by the carriage moving mechanism 40 in a state where the brush carriage 31 is connected to the connected carriage. For example, at the time of printing, with the ink carriage 21 connected to the connected carriage, the carriage moving mechanism 40 moves the ink carriage 21 together with the connected carriage in the main scanning direction Y.
