[0017] Fig. 2 shows a schematic configuration of the printer 100. Fig. 2 shows the configuration when the exterior housing of the printer 100 is removed. Fig. 2 shows a perspective view of the internal configuration of the printer 100.

[0018] 2 and 3 show an XYZ coordinate system. The X, Y, and Z axes are perpendicular to one another. The Z axis is perpendicular to the installation surface (not shown) of the printer 100. The X and Y axes are parallel to the installation surface. The X axis is an axis along the carriage guide shaft 84 shown in FIG. 2. The Y axis is an axis perpendicular to the carriage guide shaft 84. The +Z direction is the direction upward from the installation surface along the Z axis. The -Z direction is the direction downward from the installation surface along the Z axis. The +X direction is the direction from right to left of the carriage guide shaft 84 shown in FIG. 2. The -X direction is the direction from left to right of the carriage guide shaft 84 shown in FIG. 2. The +Y direction is the direction from rear to front of the printer 100 shown in FIG. 2. The -Y direction is the direction from front to rear of the printer 100 shown in FIG. 2.

[0019] The printer 100 includes a main body 10 and a moving unit 70. The main body 10 is a base that is fixed to the installation surface of the printer 100. The moving unit 70 moves along the Y axis relative to the main body 10.

[0020] The main body 10 movably supports the printing medium M. The main body 10 moves the printing medium M along the Z axis. The main body 10 includes a base 11, a medium support mechanism 30, and a drive mechanism 50.

[0021] The base unit 11 is placed on the installation surface of the printer 100. The base unit 11 supports each part of the printer 100, such as the medium support mechanism 30 and the drive mechanism 50. The base unit 11 shown in FIG. 2 includes a first base member 11a, a second base member 11b, and a main body pulley 13. The first base member 11a and the second base member 11b are arranged side by side along the Y axis.

[0022] The medium support mechanism 30 supports the printing medium M. The medium support mechanism 30 adjusts the height of the printing medium M along the Z axis. The medium support mechanism 30 includes a table 31 and a height movement mechanism 32.

[0023] The table 31 is configured so that the printing medium M can be placed thereon. The printing medium M is placed on the table 31. The table 31 is a platform that does not move along the X-axis and Y-axis. The table 31 has a medium support portion 31m and table legs 31n.

[0024] The medium support portion 31m is a member on which the printing medium M is placed. The medium support portion 31m is a rectangular flat plate. The printing medium M is placed on the medium support surface 31s of the medium support portion 31m. The medium support surface 31s is the surface of the medium support portion 31m in the +Z direction. The support surface length W of the medium support surface 31s along the X axis is equal to or approximately equal to the length of the maximum size printing medium M along the X axis. The length of the medium support surface 31s along the Y axis may be longer or shorter than the length of the maximum size printing medium M along the Y axis.

[0025] The table legs 31n support the medium support portion 31m. The table 31 shown in FIG. 2 has multiple table legs 31n. The multiple table legs 31n are arranged at the ends of the medium support portion 31m. The number and positions of the table legs 31n can be set as appropriate.

[0026] The height movement mechanism 32 moves the medium support unit 31m along the Z axis. The height movement mechanism 32 adjusts the height of the printing medium M placed on the medium support unit 31m. The height movement mechanism 32 includes a lifting motor 33, a lifting belt 37, and multiple lifting mechanisms 39.

[0027] The lift motor 33 generates a driving force that moves the table 31 along the Z axis. The lift motor 33 has an output shaft (not shown). The output shaft of the lift motor 33 rotates in a direction that moves the table 31 in the +Z direction or in a direction that moves the table 31 in the -Z direction. The printer 100 operates the lift motor 33 to move the table 31 in the +Z direction or the -Z direction.

[0028] The lifting belt 37 is a circular belt that is looped around the output shaft of the lifting motor 33 and the plurality of lifting mechanisms 39. The lifting belt 37 is driven in a circular motion by the rotation of the output shaft of the lifting motor 33. The lifting belt 37 transmits the rotation of the output shaft of the lifting motor 33 to the plurality of lifting mechanisms 39.

[0029] The lifting mechanism 39 moves the table 31 along the Z axis. The lifting mechanism 39 is provided for each of the multiple table legs 31n. The lifting mechanism 39 is composed of, for example, a ball screw, a nut, and a lifting pulley. The ball screw, nut, and lifting pulley are not shown. The ball screw is arranged along the Z axis. The ball screw is rotatably supported on the base 11. The nut is threadedly engaged with the ball screw. The nut is fixed to the table leg 31n. The lifting pulley is fixed to the upper part of the ball screw. The lifting pulley engages with the lifting belt 37. The lifting pulley receives the rotation of the output shaft of the lifting motor 33 via the lifting belt 37. When the lifting pulley rotates, the ball screw rotates. The rotation of the ball screw moves the nut and the table leg 31n along the Z axis.

[0030] The driving mechanism 50 moves the moving part 70 along the Y axis. The driving mechanism 50 includes a first guide shaft 51a, a second guide shaft 51b, and a frame driving part 60.

[0031] The first guide shaft 51a and the second guide shaft 51b guide the movement of the moving unit 70 along the Y axis. The first guide shaft 51a and the second guide shaft 51b are suspended between the first base member 11a and the second base member 11b. The first guide shaft 51a and the second guide shaft 51b are shaft-shaped members arranged along the Y axis. The first guide shaft 51a is fixed to an end position of the base unit 11 in the -X direction. The second guide shaft 51b is fixed to an end position of the base unit 11 in the +X direction.

[0032] The frame driving unit 60 includes a frame moving motor 61, a driving belt 63, a speed change mechanism 65, and a transmission belt 67. Although the frame driving unit 60 shown in Fig. 2 is disposed in a position on the -X direction of the base unit 11, it may be disposed in a position on the +X direction. The frame driving unit 60 is preferably disposed in a position on the -X direction.

[0033] The frame movement motor 61 generates a driving force that moves the movement unit 70 along the Y axis. The frame movement motor 61 has a rotation shaft 61a. The rotation shaft 61a of the frame movement motor 61 rotates in a direction that moves the movement unit 70 in the +Y direction and in a direction that moves the movement unit 70 in the -Y direction. The printer 100 operates the frame movement motor 61 to move the movement unit 70 in the +Y direction or the -Y direction.

[0034] The drive belt 63 transmits the drive force generated by the frame moving motor 61 to the speed change mechanism 65. The drive belt 63 is a circular belt that is stretched between the rotation shaft 61a of the frame moving motor 61 and the speed change mechanism 65.

[0035] The transmission mechanism 65 changes the speed of rotation by the rotating shaft 61a. The transmission mechanism 65 has, for example, a first pulley and a second pulley. The details of the first pulley and the second pulley are not shown. The drive belt 63 is wound around the first pulley. The transmission belt 67 is wound around the second pulley. The transmission mechanism 65 rotates the second pulley by the driving force transmitted from the drive belt 63 to the first pulley. The second pulley drives the transmission belt 67. The transmission mechanism 65 transmits the driving force of the frame moving motor 61 to the transmission belt 67 at a reduction ratio corresponding to the ratio between the diameters of the first pulley and the second pulley.

[0036] The transmission belt 67 transmits the driving force to the moving part 70. The transmission belt 67 is a circular belt that is stretched between the speed change mechanism 65 and the main body pulley 13. The main body pulley 13 is disposed on the second base member 11b. The main body pulley 13 is installed so as to be rotatable relative to the second base member 11b. The transmission belt 67 is disposed along the first guide shaft 51a.

[0037] The moving unit 70 moves relative to the printing medium M. The moving unit 70 moves along the Y axis relative to the printing medium M. The moving unit 70 includes a main frame 71 and a recording unit 90.

[0038] The main frame 71 is a plate-like member disposed along the X-axis. The main frame 71 moves along the Y-axis. The length of the main frame 71 along the X-axis is longer than the length of the base unit 11 along the X-axis. The main frame 71 includes a first leg 73a, a second leg 73b, a carriage support frame 81, a carriage drive motor 82, a transmission mechanism 83, a carriage guide shaft 84, and a carriage drive belt 85.

[0039] The first leg portion 73a and the second leg portion 73b fixedly support the main frame 71. The first leg portion 73a and the second leg portion 73b support the main frame 71 at a position of the main frame 71 in the −Z direction.

[0040] The first leg 73a is disposed at a position in the -X direction of the main frame 71. The first leg 73a fits onto the first guide shaft 51a. The first leg 73a is movable along the first guide shaft 51a. The first leg 73a has a first belt connection portion 79a. The first leg 73a is fixed to the transmission belt 67 via the first belt connection portion 79a. When the transmission belt 67 is driven in a circular motion, the driving force is transmitted to the first leg 73a via the first belt connection portion 79a. The driving force transmitted to the first leg 73a causes the moving unit 70 to move along the Y axis.

[0041] The second leg 73b is disposed in a position in the +X direction of the main frame 71. The second leg 73b fits onto the second guide shaft 51b. The second leg 73b is guided by the second guide shaft 51b. The second leg 73b is movable in the +Y direction and the -Y direction along the second guide shaft 51b.

[0042] The carriage support frame 81 supports a carriage 91, which will be described later. The carriage support frame 81 is a plate-shaped member that is disposed along the X-axis. The carriage support frame 81 is supported by the main frame 71.

[0043] The carriage drive motor 82 generates a driving force that moves the carriage 91. The carriage drive motor 82 is supported by a carriage support frame 81. The carriage drive motor 82 shown in FIG. 2 is disposed at a position on the −X direction side of the carriage support frame 81.

[0044] The transmission mechanism 83 transmits the driving force generated by the carriage drive motor 82 to the carriage drive belt 85. The transmission mechanism 83 has a transmission pulley 83a, a two-stage transmission pulley 83b, and a transmission belt 83c. The transmission pulley 83a is fixed to the drive shaft of the carriage drive motor 82. The transmission belt 83c is a circular belt that is stretched between the transmission pulley 83a and the two-stage transmission pulley 83b. The two-stage transmission pulley 83b has a small pulley and a large pulley with a larger diameter than the small pulley. The transmission belt 83c is wound around the large pulley. The carriage drive belt 85 is wound around the small pulley. The transmission belt 83c is driven in a circular motion by the rotation of the carriage drive motor 82. The transmission belt 83c rotates the large pulley. The transmission belt 83c rotates the large pulley, thereby rotating the small pulley. The small pulley drives the carriage drive belt 85 in a circular motion. The rotation of the carriage drive motor 82 is transmitted to the carriage drive belt 85 at a reduction ratio corresponding to the ratio of the diameters of the large pulley and the small pulley.

[0045] The carriage guide shaft 84 guides the carriage 91. The carriage guide shaft 84 is fixed to the carriage support frame 81. The carriage guide shaft 84 is disposed along the X-axis. The carriage guide shaft 84 guides the carriage 91 along the X-axis.

[0046] The carriage drive belt 85 moves the carriage 91. The carriage drive belt 85 is a circular belt that is stretched between the transmission mechanism 83 and a carriage drive pulley (not shown). The transmission mechanism 83 is disposed in the -X direction of the carriage support frame 81. The carriage drive pulley is disposed in the +X direction of the carriage support frame 81. The carriage drive belt 85 is disposed along the carriage guide shaft 84.

[0047] The printer 100 may also include a height detection unit 88. The height detection unit 88 detects the height of the print medium M placed on the table 31. The height detection unit 88 has a contact plate 89 that protrudes downward from the lower end of the main frame 71. The contact plate 89 is a plate-shaped member. The contact plate 89 is attached to the main frame 71 so that it can rotate about an imaginary rotation axis parallel to the X-axis. The contact plate 89 rotates when it comes into contact with the print medium M or the medium support unit 31m. An arm (not shown) is formed on the contact plate 89. The arm is displaced as the contact plate 89 rotates. The displacement of the arm is detected by a displacement sensor (not shown). The displacement sensor is provided in the height detection unit 88. The displacement sensor is a magnetic sensor, a reflective optical sensor, or a transmissive optical sensor. The height detection unit 88 detects the rotation of the contact plate 89 as the displacement sensor detects the displacement of the arm. The height detection unit 88 detects the height of the print medium M by detecting the rotation of the contact plate 89 .

[0048] The recording unit 90 performs printing on the print medium M. The recording unit 90 is supported by the moving unit 70. The recording unit 90 includes a carriage 91 and a printing unit 93.

[0049] The carriage 91 carries the printing unit 93. The carriage 91 is connected to a carriage drive belt 85. When the carriage drive belt 85 is driven to rotate, the carriage 91 moves. The carriage 91 is supported by a carriage guide shaft 84. The carriage 91 is movable along the carriage guide shaft 84. The carriage 91 is movable along the X axis in the +X direction or the -X direction. The carriage 91 moves along the X axis between an end position in the -X direction and an end position in the +X direction. The carriage drive belt 85 moves the carriage 91 between an end position in the -X direction and an end position in the +X direction by driving the carriage drive motor 82.

[0050] The end position in the -X direction is referred to as the home position. The home position is a position different from on the printing medium M. The home position is a position in the -X direction or +X direction relative to the printing medium M. In the case of the printer 100 shown in FIG. 2, the home position is the -X direction position of the printing medium M and the medium support unit 31m that supports the printing medium M. The carriage 91 located at the home position may face a maintenance mechanism that performs maintenance such as flushing and cleaning of the printing unit 93. The maintenance mechanism is not shown. The maintenance mechanism is located at a position facing the carriage 91 located at the home position, or at a position adjacent to the facing position. FIG. 2 shows the recording unit 90 located at the home position with a dashed line.

[0051] The end position in the +X direction is the return position. The carriage 91 stops at the return position. The carriage 91 moves in the +X direction from the home position. The carriage 91 passes over the printing medium M from the home position and stops at the return position. The return position is a position in the +X direction relative to the home position. After stopping at the return position, the carriage 91 moves in the -X direction. The carriage 91 passes over the printing medium M from the return position and moves to the home position.

[0052] The printing unit 93 prints on the printing medium M. As the carriage 91 moves along the X axis, the printing unit 93 moves in the +X direction or the -X direction. As the main frame 71 moves along the Y axis, the printing unit 93 moves in the +Y direction or the -Y direction. The printer 100 can move the printing unit 93 along the X axis and the Y axis relative to the table 31. The printing unit 93 can eject ink onto the entire printing medium M supported by the table 31.

[0053] Figure 3 shows a cross-sectional configuration of the printing unit 93. Figure 3 shows an XZ cross section. The printing unit 93 has a print head unit 94 and a UV lamp 96. The printing unit 93 has, in order from the position in the -X direction along the X axis, a first UV lamp 96a, the print head unit 94, and a second UV lamp 96b.

[0054] The print head unit 94 includes one or more print heads 95. The print head unit 94 shown in Figure 3 includes a first print head 95a, a second print head 95b, a third print head 95c, and a fourth print head 95d. The print head unit 94 shown in Figure 3 includes, but is not limited to, four print heads 95. The print head unit 94 includes one or more print heads 95. It is preferable that the print head unit 94 includes multiple print heads 95.

[0055] The print head 95 ejects ink as a liquid onto the print medium M. The print head 95 has a plurality of nozzles (not shown) that eject ink. The nozzles open on the -Z direction surface of the print head 95. When the print head 95 ejects ink from the nozzles, the ejected ink flies from the -Z direction surface of the print head 95 toward the print medium M placed on the table 31. The ink lands on the print medium M.

[0056] The ink ejected by the print head 95 is ultraviolet curable ink, which contains a resin material, a photopolymerization initiator, and a solution as its main materials.

[0057] The resin material is a material that forms a resin film. The resin material is liquid at room temperature. The resin material has a crosslinkable group. The resin material is preferably a material that becomes a polymer by polymerization. The resin material is preferably in the form of an oligomer. The resin material is more preferably in the form of a monomer.

[0058] The photopolymerization initiator functions as a curing agent. The photopolymerization initiator acts on the crosslinkable groups of the resin material to promote the crosslinking reaction. An example of the photopolymerization initiator is benzyl dimethyl ketal.

[0059] The solution is a solvent or a dispersion medium. The solution adjusts the viscosity of the resin material. By adding the solution to the ultraviolet curable ink, the ultraviolet curable ink is adjusted to a predetermined viscosity.

[0060] The ultraviolet curable ink may contain a colorant and a functional material. The ultraviolet curable ink has a unique function due to the inclusion of the colorant and the functional material. The colorant is a pigment or a dye. The ultraviolet curable ink contains, for example, cyan, magenta, yellow, and white pigments as the colorant. One example of the functional material is a surface modification material that is lyophilic or lyophobic.

[0061] Each of the multiple print heads 95 ejects ultraviolet curable ink onto the print medium M. It is preferable that the print head unit 94 ejects multiple types of ultraviolet curable ink onto the print medium M using the multiple print heads 95. The multiple types of ink differ from each other in at least one of the resin material, photopolymerization initiator, and solution. The multiple types of ink may also differ from each other in the pigments and functional materials added.

[0062] The multiple types of UV-curable inks ejected by the print head unit 94 may include clear ink. The clear ink contains a photopolymerization initiator and a polymerizable compound. The clear ink is used to protect coatings formed with other inks and to adjust the glossiness of printed materials. The content of pigment contained in the clear ink is preferably 0.2 mass % or less of the total amount of clear ink. It is more preferable that the clear ink does not contain a colorant.

[0063] As an example, the first print head 95a, second print head 95b, third print head 95c, and fourth print head 95d each eject different types of ultraviolet curable ink. The first print head 95a ejects cyan ink containing a cyan pigment. The second print head 95b ejects magenta ink containing a magenta pigment. The third print head 95c ejects clear ink. The fourth print head 95d ejects yellow ink containing a yellow pigment.

[0064] The UV lamp 96 photo-cures the ultraviolet curable ink ejected onto the printing medium M. UV is an abbreviation for ultraviolet. The UV lamp 96 irradiates the printing medium M with ultraviolet rays. The UV lamp 96 irradiates the printing medium M with ultraviolet rays, thereby curing the ultraviolet curable ink ejected onto the printing medium M.

[0065] The UV lamp 96 is composed of a metal halide lamp, a xenon lamp, a carbon arc lamp, a chemical lamp, a low-pressure mercury lamp, a high-pressure mercury lamp, or the like. The UV lamp 96 may also be composed of an ultraviolet light-emitting diode, an ultraviolet light-emitting semiconductor laser, or the like. The UV lamp 96 emits ultraviolet light with a wavelength of 365 nm or more and 410 nm or less. The peak irradiation intensity of the UV lamp 96 is 200 mW / cm. 2 It is preferable that the power is equal to or higher than 800 mW / cm 2 That's all.

[0066] 3 includes a first UV lamp 96a and a second UV lamp 96b as UV lamps 96. The printing unit 93 includes the second UV lamp 96b, but is not limited to this. The printing unit 93 does not necessarily have to include the second UV lamp 96b. It is preferable that the printing unit 93 includes the second UV lamp 96b.

[0067] The printing unit 93 can print Braille characters 400. The print head unit 94 ejects ultraviolet curable ink onto the print medium M. When the print head unit 94 ejects the ultraviolet curable ink onto the print medium M, raised portions are formed on the print medium M. The raised portions thus formed function as dots 403 of the Braille characters 400. The printer 100 can print Braille characters 400.

[0068] Fig. 4 shows the configuration of a Braille character 400. Fig. 4 shows a schematic diagram of the configuration of one Braille character 400.

[0120] The data generation unit 253 determines the number of Braille patch images 411 for each setting value from the number setting value. The Braille test chart 410 is made up of one reference Braille patch image 411a and multiple adjusted Braille patch images 411b. The data generation unit 253 determines the number of adjusted Braille patch images 411b using the number setting value. When the number setting value is 3 and there are three setting values, namely, the diameter setting value, the height setting value, and the curvature radius setting value, the Braille test chart 410 is made up of 27 Braille patch images 411. The Braille test chart 410 is made up of one reference Braille patch image 411a and 26 adjusted Braille patch images 411b.

[0121] The data generation unit 253 generates adjustment parameters corresponding to each of the multiple adjusted Braille patch images 411b. The data generation unit 253 generates the adjustment parameters using the reference parameters and interval information. If the reference parameters include a diameter setting value, a height setting value, and a curvature radius setting value, the data generation unit 253 generates the adjustment parameters using one of the diameter adjustment value, the height adjustment value, and the curvature radius adjustment value. The adjustment parameters include an adjusted diameter setting value, an adjusted height setting value, and an adjusted curvature radius setting value. The data generation unit 253 makes at least one of the adjusted diameter setting value, adjusted height setting value, and adjusted curvature radius setting value included in the adjustment parameters different from the diameter setting value, height setting value, and curvature radius setting value included in the reference parameters. The data generation unit 253 makes the reference parameters different from the adjustment parameters.

[0122] As an example, the data generation unit 253 differentiates the adjusted diameter setting value included in the adjustment parameters from the diameter setting value included in the reference parameters. The data generation unit 253 generates the adjusted diameter setting value included in the adjustment parameters by adding or subtracting the diameter adjustment value to or from the diameter setting value included in the reference parameters. The data generation unit 253 generates the adjusted diameter setting value included in the adjustment parameters by adding or subtracting a multiple of the diameter adjustment value to or from the diameter setting value included in the reference parameters. The data generation unit 253 generates the adjusted height setting value and the adjusted curvature radius setting value included in the adjustment parameters using a similar method.

[0123] When the data generation unit 253 includes a reference parameter including a number of ink layers setting value instead of a height setting value, the data generation unit 253 generates an adjustment parameter including an adjusted number of ink layers setting value. The data generation unit 253 converts the height adjustment value into a number of ink layers adjustment value. The number of ink layers adjustment value is the number of ink layers 407 corresponding to the height adjustment value. The data generation unit 253 generates an adjusted number of ink layers setting value using the number of ink layers setting value and the number of ink layers adjustment value. When a height adjustment value is set, the adjusted number of ink layers setting value differs from the number of ink layers setting value. The adjusted number of ink layers setting value corresponds to an example of a second number of ink layers setting value.

[0124] The data generation unit 253 generates print data including the reference parameters and multiple adjustment parameters, and then transmits the Braille test chart print data to the printer 100 via the communication control unit 255. The printer 100 receives the Braille test chart print data. The printer 100 prints a Braille test chart 410 based on the Braille test chart print data.

The input unit 230 inputs designation data corresponding to the designation input operation. The designation data includes patch designation information indicating the desired Braille patch image 411. The input unit 230 transmits the designation data to the data generation unit 253. The data generation unit 253 identifies the Braille patch image 411 using the patch designation information. The data generation unit 253 stores Braille parameters for printing the identified Braille patch image 411 in the storage unit 220. The Braille parameters are one of the reference parameters and multiple adjustment parameters. When the print control device 200 receives a print instruction to print Braille 400, it generates print data including the Braille parameters. The print control device 200 causes the printer 100 to print based on the print data including the Braille parameters.

[0126] The print control device 200 includes a data generation unit 253 that generates test chart print data that causes the printer 100, which ejects ink, to print a Braille test chart 410 made up of multiple Braille patch images 411, including a reference Braille patch image 411a and an adjusted Braille patch image 411b, and a communication control unit 255 that transmits the test chart print data to the printer 100. The data generation unit 253 differentiates a reference parameter related to a reference point 403a included in the reference Braille patch image 411a from an adjustment parameter related to an adjustment point 403b included in the adjusted Braille patch image 411b. When printing Braille with the printer 100, the print result varies depending on the type of recording paper, etc. The print control device 200 can cause the printer 100 to print a Braille test chart 410 that includes Braille 400 printed under different printing conditions. By evaluating the Braille test chart 410, the user can determine the printing conditions for printing the desired Braille 400.

[0127] The input unit 230 receives braille interval information indicating the difference between the reference parameter and the adjustment parameter. The data generation unit 253 preferably generates the adjustment parameter based on the reference point setting information and the braille interval information. The user can adjust the difference in shape between the multiple Braille patch images 411 in the Braille test chart 410 to a desired difference.

[0128] When the input unit 230 receives reference point setting information including a height setting value, it is preferable that the data generation unit 253 generates a reference parameter including an ink layer number setting value, which is the number of ink layers 407 corresponding to the height setting value, and generates an adjustment parameter including an adjustment ink layer number setting value different from the ink layer number setting value. The print control device 200 can convert the shape of the point 403 into data that is easily compatible with the printing conditions of the printer 100 .
