[0005] However, there is room for improvement in the processing device of Patent Document 1. Specifically, there is a problem in that the installation environment is limited because vibrations and vibration noise caused by vibration energy emitted from the vibration generating source are transmitted to the surroundings of the processing device.

[0009] Embodiment 1 ***Printing System Overview*** FIG. 1 is a schematic configuration diagram of a printing system according to the first embodiment. The printing device 200 of this embodiment is a printing device that records an image on the fabric M, and includes a processing unit 30 that applies processing to the printed fabric M to improve the texture of the fabric M.

[0010] The printing apparatus 200 is composed of a printing unit 10, a drying unit 20, a processing unit 30, a control device 150, etc. In the printing apparatus 200, the fabric M is transported by a roll-to-roll method. Specifically, the unprinted fabric M is pulled out from the first roll R1, printed in the printing unit 10, dried in the drying unit 20, and then subjected to texture improvement treatment in the processing unit 30. The fabric M is then wound up as a second roll R2 by the winding section 40.

[0011] ***Printing unit configuration*** The printing unit 10 has a housing 10A, and a feed unit 12 is supported on the outside of the housing 10A. The feed unit 12 has a feed motor 12M, which is a drive source that rotates the attached first roll body R1 in the unwinding direction. The printing unit 10 includes a conveying section 13 that conveys the fabric M unwound from the feeding section 12. The conveying section 13 includes a drive roller 14A, a driven roller 14B, and an endless conveying belt 15 wound around both rollers 14A and 14B. The conveying section 13 also includes a conveying motor 13M that is a drive source that rotates the drive roller 14A. The conveying belt 15 rotates when the conveying motor 13M is driven. The fabric M on the conveying belt 15 is conveyed in the conveying direction indicated by the arrow when the conveying belt 15 rotates. The driven roller 14B is paired with a roller 43, and supplies the fabric M onto the conveying belt 15 while nipping the fabric M between the roller 43 and the driven roller 14B.

[0012] As shown in FIG. 1, a printing unit 16 that prints on the fabric M transported along the first transport path T1 is disposed inside the housing 10A. The printing unit 16 includes a print head 18. The print head 18 ejects a liquid such as ink supplied from a liquid container such as an ink cartridge or ink tank (not shown) onto the fabric M. The liquid container contains the same type of liquid as the liquid ejected by the print head 18. The liquid ejected by the print head 18 is not limited to ink, but may include a pre-treatment liquid that is ejected before printing onto the fabric M, or a post-treatment liquid that is ejected after printing onto the fabric M. The printing process performed on the fabric M by the printing unit 10 may include a process of ejecting a pre-treatment liquid, a post-treatment liquid, or the like onto the fabric M, in addition to a process of ejecting ink onto the fabric M.

[0013] For example, if the printing unit 10 is configured to perform color printing using N colors of ink, N liquid containers each containing one of the N colors of ink are attached to attachment portions provided at predetermined positions on the printing unit 10. If the N colors are, for example, four colors, four liquid containers each containing one of the four colors of ink, cyan, magenta, yellow, and black, are attached to the attachment portions. Color printing is not limited to three or four colors, and may be one, two, or five or more colors.

[0014] The printing unit 10 is, for example, a serial digital textile printer. The serial printing section 16 includes a carriage 17 that is configured to be movable in the width direction of the fabric M, and a print head 18 fixed to the carriage 17. The print head 18 is fixed to the surface of the carriage 17 that faces the first transport path T1, and moves back and forth in the width direction X together with the carriage 17. The print head 18 has a plurality of nozzles (not shown) that open to a nozzle surface that faces the fabric M.

[0015] The carriage 17 is driven by a carriage motor 17M. The printing unit 10 is equipped with a power transmission mechanism (not shown) that converts the power of the carriage motor 17M into linear motion of the carriage 17 in the width direction X. The power transmission mechanism is, for example, a belt-type power transmission mechanism. The carriage 17 is guided by a guide rail (not shown) so that it can move in the width direction X. The carriage 17 is fixed to a part of an endless timing belt that constitutes the belt-type power transmission mechanism, and when the carriage motor 17M is driven, the timing belt rotates forward and backward, causing the carriage 17 to move back and forth along the width direction X.

[0016] The print head 18 prints on the fabric M by ejecting liquid such as ink from nozzles while the carriage 17 moves in the width direction X. One movement of the print head 18 in the width direction X is called one pass. An image or the like based on print data is printed on the fabric M by alternating a printing operation in which the carriage 17 moves in the width direction X and the print head 18 prints for one pass or multiple passes, and a transport operation in which the fabric M is transported to the next printing position. The printing unit 16 may be a line printing unit. The line printing unit 16 includes a line printing head 18, a so-called line head, having a plurality of nozzles across the entire range of the maximum expected width of the fabric M. In the line printing unit 10, the transport unit 13 transports the fabric M at a constant speed. The print head 18 prints an image or the like on the fabric M by ejecting liquid such as ink from the nozzles onto the fabric M transported at the constant speed.

[0017] ***Drying unit configuration*** The drying unit 20 performs a drying process on the fabric M after the printing process by the printing unit 10, that is, the printed fabric M. The drying unit 20 has a second transport path T2 along which the fabric M is transported within the housing 21. The drying unit 20 also has a heater 22 within the housing 21 that serves as a heat source for drying the fabric M. The heater 22 is housed in an air duct 23 that is located above the second transport path T2 within the housing 21. A fan 24 is disposed in the air duct 23 at a portion that communicates with the outside of the housing 21. When the fan 24 is driven, air is taken in from outside the housing 21 into the air duct 23, and the taken-in air is heated as it passes through the heater 22. The heated air is blown as hot air or warm air from the air outlet of the air duct 23 onto the printed surface of the fabric M on the second transport path T2.

[0018] Therefore, the liquid such as ink printed on the fabric M by the printing unit 10 dries while the fabric M is transported along the second transport path T2 of the drying unit 20. Then, the dried fabric M is transported from the drying unit 20 to the processing unit 30. Further, the exhaust heat in the drying unit 20 is sucked by the exhaust fan 70, passes through the exhaust duct 71, and is discharged from the exhaust port 71b.

[0019] A buffer section 31 is provided between the drying unit 20 and the processing unit 30. The buffer section 31 includes two roller pairs 41 and 42. As shown in FIG. 1, the buffer section 31 creates a predetermined length of slack in the fabric M between the roller pair 41 and the roller pair 42. This slack in the fabric M serves as a buffer between the printing unit 10 and the processing unit 30. For example, even if the printing unit 10 temporarily stops conveying the fabric M, the processing in the processing unit 30 can continue by the amount of slack in the fabric M created in the buffer section 31.

[0020] ***Processing unit configuration*** The processing unit 30 is composed of a processing device 100, a processing device 110, etc. The processing device 100 corresponds to a first processing device, and the processing device 110 corresponds to a second processing device. The fabric M is transported along a third transport path T3, and a processing device 100 is provided on the upstream side of the third transport path T3, and a processing device 110 is provided on the downstream side thereof. As shown in Fig. 1, the processing device 100 has a first contact portion 2 and a second contact portion 3 arranged to sandwich the fabric M, and applies vibrations to the front and back surfaces of the fabric M to perform a texture processing. Similarly, the processing device 110 has a third contact portion 4 and a fourth contact portion 5 arranged to sandwich the fabric M. In other words, the processing device 110 as the second processing device is arranged downstream of the processing device 100 in the conveying direction of the fabric M. Details of the processing devices 100 and 110 will be described later.

[0021] The processing unit 30 is provided with a cooling section 38, heating sections 36 and 37, tension adjusting sections 34 and 35, and a cleaning section 39. Cooling section 38 includes cooling duct section 77 that takes in outside air from outside housing 30A, and cooling fan 78 disposed within cooling duct section 77. Cooling section 38 cools fabric M, which has been heated by the drying process in drying unit 20 and has a temperature higher than room temperature, to a temperature close to room temperature.

[0022] The heating section 36 includes a duct section 73 branching off from the exhaust duct 71, and a heating fan 74 disposed within the duct section 73. The heating section 36 blows hot waste air by driving the heating fan 74, and heats the fabric M before it is processed in the processing device 100. The fabric M warms and becomes soft due to heating, allowing the processing in the processing device 100 to be carried out efficiently. The heating section 37 includes a duct section 75 branching off from the exhaust duct 71, and a heating fan 76 disposed within the duct section 75. The heating section 37 blows hot waste air by driving the heating fan 76, and heats the fabric M before it is processed in the processing device 110. The fabric M warms and becomes soft due to heating, allowing the processing in the processing device 110 to be carried out efficiently.

[0023] The tension adjusting unit 34 includes two pairs of rollers 61, 62 that hold the fabric M. The pair of rollers 61 is provided upstream of the processing device 100, and the pair of rollers 62 is provided downstream of the processing device 100. The tension adjusting unit 34 adjusts the tension of the fabric M to be processed by the processing device 100 using the two pairs of rollers 61, 62 to a tension suitable for processing by the processing device 100. The tension adjusting unit 35 includes two pairs of rollers 65, 66 that hold the fabric M. The pair of rollers 65 is provided upstream of the processing device 110, and the pair of rollers 66 is provided downstream of the processing device 110. The tension adjusting unit 35 adjusts the tension of the fabric M to be processed by the processing device 110 using the two pairs of rollers 65, 66 to a tension suitable for processing by the processing device 110.

[0024] The cleaning unit 39 includes removal members 91 and 92 that clean the fabric M while coming into contact with the fabric M. The removal member 91 cleans the fabric M while contacting the printed surface of the fabric M. The removal member 92 cleans the fabric M while contacting the back surface of the fabric M, which is the surface opposite the printed surface. The removal members 91 and 92 are, for example, rotary brushes. The removal members 91 and 92 have a width dimension that allows them to clean the entire width of the fabric M. The cleaning unit 39 also includes collection units 95 and 96 that collect waste powder such as fiber powder generated by the removal members 91 and 92 cleaning the fabric M. The collection unit 95 is a waste powder box that collects waste powder generated by the removal member 91, and the collection unit 96 is a waste powder box that collects waste powder generated by the removal member 92.

[0025] After the processing in the processing unit 30, the fabric M is wound onto the second roll body R2 by the winding motor 40M of the winding section 40.

[0026] The control device 150 is a control circuit configured with one or more processors, and operates in accordance with a control program stored in a memory circuit (not shown) to comprehensively control the operation of each part of the printing device 200. The control device 150 includes a drive unit 140 that drives and controls the processing devices 100 and 110. In other words, the printing device 200 includes processing devices 100, 110 and a printing unit 10 that prints on the fabric M, and when the processing device 100 having a first abutment portion 2 and a second abutment portion 3 is considered to be the first processing device, the printing device 200 further includes processing device 110 as the second processing device that is arranged downstream of the processing device 100 in the conveying direction of the fabric M, and the processing device 110 has a third abutment portion 4 and a fourth abutment portion 5 that are arranged on either side of the fabric M.

[0027] ***Processing equipment configuration*** Fig. 2 is a side view of the processing apparatus and corresponds to Fig. 1. Fig. 3 is an exploded perspective view of the processing apparatus. The processing device 100 is made up of a vibration applying unit 88, a first contact unit 2, a second contact unit 3, etc. The vibration applying unit 88 is made up of a first driving unit 51 and a second driving unit 52. The first driving section 51 is disposed below the fabric M and drives the first contact section 2. The first contact section 2 is composed of a support plate 2a and a plurality of protrusions 2b protruding from the support plate 2a. The second driving section 52 is disposed above the fabric M and drives the second contact section 3. The second contact section 3 is composed of a support plate 3a and a plurality of protrusions 3b protruding from the support plate 3a. 2, fabric M is inserted between first contact portion 2 and second contact portion 3. Multiple protrusions 2b and multiple protrusions 3b are arranged alternately in a plane.

[0028] As shown in FIG. 3, a drive motor 50 is provided on the first drive unit 51 side. The rotation shaft of the drive motor 50 is directly connected to a gear 81. A transmission shaft 25 is connected to the gear 81, and a gear 83 is provided on the transmission shaft 25. The first drive unit 51 is driven by the gear 83, which will be described in detail later. A gear 82 of the same size is disposed on top of the gear 81. Here, as shown in FIG. 3, the gear 82 rotates in the direction opposite to the rotation direction of the gear 81. A transmission shaft 26 is connected to the gear 82, and a gear 84 is provided on the transmission shaft 26. The gear 84 drives the second drive unit 52. As a result, the first drive unit 51 and the second drive unit 52 are driven in opposite phases. Note that the above-mentioned components are housed in a housing 100c of the processing device 100, but in FIG. 3, part of the housing 100c has been removed to show the internal structure.

[0029] ***Scotch yoke mechanism*** Fig. 4 is a perspective view of the second drive unit as seen from the P direction in Fig. 3. Fig. 5 is an explanatory diagram of a Scotch yoke mechanism. Here, the Scotch yoke mechanism used in the vibration applying unit 88 will be described using the second driving unit 52. The first driving unit 51 has the same configuration. As shown in FIG. 4, the second driving section 52 is made up of a driving shaft 53, a gear 86, a pair of bearings 54, a pair of drivers 55, and the like. The pair of bearings 54 are bearings that support the drive shaft 53 so that it can rotate around a rotation axis 60, and are fixed to a housing 100c (FIG. 3) of the processing device 100. Note that the housing 100c is not shown in FIG. 4. The rotation axis 60 is also referred to as a rotation center 60.

[0030] A gear 86 is provided on the drive shaft 53. The gear 86 is connected to the gear 84, and the gear 86 rotates in the opposite direction to the rotation direction of the gear 84. When the gear 86 rotates, the drive shaft 53 also rotates together. One end of the drive shaft 53 passes through the bearing portion 54, and the driver 55 is attached to that end.

[0031] As shown in Figure 5, an eccentric pin 56 is provided at one end of the drive shaft 53. The eccentric pin 56 is a cylindrical pin, and its center is eccentric from the rotation center 60 of the drive shaft 53. One end of the driver 55 is fixed to the support plate 3a of the second contact portion 3. An elongated hole 58 is provided at the other end of the driver 55. The longitudinal direction of the elongated hole is aligned with the feed direction of the fabric M. The driver 55 is attached with the eccentric pin 56 of the drive shaft 53 inserted into the elongated hole 58. An eccentric pin 56 and driver 55 with the same configuration are provided at the other end of the drive shaft 53 (Figure 4). The eccentric pin 56 of the drive shaft 53 and the elongated hole 58 of the driver 55 constitute a Scotch yoke mechanism. More specifically, when the drive shaft 53 rotates, the eccentric pin 56 causes the driver 55 to reciprocate in a direction that intersects with the elongated hole 58. As shown on the left side of Figure 5, the state of contact with the fabric M indicated by the white arrow 1 and the state of separation from the fabric M indicated by the white arrow 2 are repeated. In other words, the second contact portion 3 repeatedly strikes and separates from the fabric M.

[0032] Return to Figure 2. The first drive unit 51 also has the same Scotch yoke mechanism as the second drive unit 52, so as shown in Figure 2, the first abutment unit 2 and the second abutment unit 3 synchronously repeat the state of abutting against the fabric M as indicated by the white arrow 1 and the state of moving away from the fabric M as indicated by the white arrow 2. In other words, the processing device 100 includes a contact portion having a plurality of protrusions 2b, 3b that contact the fabric M, and a vibration applying portion 88 that applies vibrations to the contact portion. The contact portion has a first contact portion 2 and a second contact portion 3 that are arranged on either side of the fabric M. The vibration applying portion 88 includes a first drive portion 51 that applies vibrations to the first contact portion 2 and a second drive portion 52 that applies vibrations to the second contact portion 3. The first drive portion 51 and the second drive portion 52 operate synchronously. The first drive portion 51 and the second drive portion 52 are configured as a Scotch yoke mechanism.

[0033] 6 is a graph showing waveforms of the driving modes of the first driving unit and the second driving unit, in which the horizontal axis represents time and the vertical axis represents driving amplitude (driving voltage). 6 shows the driving mode of the first driving unit 51, and graph 152 shows the driving mode of the second driving unit 52. As shown in graphs 151 and 152, it can be seen that the waveform of the vibration applied to the first contact portion 2 by the first driving unit 51 and the waveform of the vibration applied to the second contact portion 3 by the second driving unit 52 are in opposite phases. In this way, the first contact portion 2 and the second contact portion 3 synchronously contact and separate from each other on both sides of the fabric M, thereby canceling out the movement of the center of gravity in the processing device 100 and reducing vibration. Experiments conducted by the inventors have confirmed that no significant vibration occurs, especially when driven at high speed.

[0034] In a preferred example, the frequency of graphs 151 and 152 is 1 Hz or more and 100 Hz or less. The drive amount of first contact portion 2 and second contact portion 3 is 1 mm or more and 10 mm or less. These values are merely examples, and may be set appropriately depending on the type of fabric M and the printing conditions. The waveforms of graphs 151 and 152 are not limited to sine waves, and may be any waveforms as long as they are in opposite phases. For example, they may be rectangular waves, triangular waves, or a combination of these.

[0035] ***Protrusion type*** Fig. 7 is a side view showing one embodiment of the protrusion of the first processing device, and corresponds to Fig. 1. Fig. 8 is a side view showing one embodiment of the protrusion of the second processing device, and corresponds to Fig. 1. As shown in FIG. 7, the protrusion 2b of the first contact portion 2 of the processing device 100 is a metal, conical protrusion with a rounded tip. The protrusion 3b of the second contact portion 3 is also a protrusion similar to the protrusion 2b. By hitting the fabric M from the front and back with the protrusions 2b and 3b, the fabric M is deformed in a wavy manner and its hardness is loosened. In addition, the tips of the protrusions 2b and 3b destroy part of the ink layer and resin layer. The processing by the processing device 100 corresponds to rough processing, which loosens and partially destroys the ink layer and resin layer that cause the hardness of the printed fabric M.

[0036] 8, the protrusion 4b of the third contact part 4 of the processing device 110 is a rounded protrusion made of metal, such as a convex spherical or wave-shaped protrusion. The protrusion 5b of the fourth contact part 5 is also a protrusion similar to the protrusion 4b. The protrusions 4b and 5b are alternately arranged in a plane. The roughened surface that has been roughened by the rough processing is smoothed by sandwiching the fabric M between the protrusions 4b and 5b from the front and back. The processing by the processing device 110 corresponds to a finishing process, and smoothes the surface layer of the fabric M to a desired texture. In other words, the shapes of the protrusions 2b, 3b provided on the first contact portion 2 and the second contact portion 3 are different from the shapes of the protrusions 4b, 5b provided on the third contact portion 4 and the fourth contact portion 5.

[0037] ***About texture processing*** The texture processing performed by the processing devices 100 and 110 will now be described. First, texture refers to the texture of the fabric, such as the feel to the touch, the feel to the skin, etc. The original texture and quality of the fabric M tends to deteriorate after printing, and there is a demand for improvement in this regard.

[0038] In the processing devices 100 and 110, the fabric M is subjected to at least one type of processing selected from bending, beating, stretching, and rubbing. Bending refers to a process of repeatedly deforming the fabric M to increase the bending angle of the fibers. Bending reduces the association forces between parallel fibers in the fabric M, releases the junctions between intersecting fiber bundles, and causes partial structural destruction of the fibers, reducing the stiffness of the fabric and improving its texture. Beating refers to a process in which protrusions are used to beat both the front and back of fabric M. Beating repeatedly compresses and restores the fiber bundles of fabric M, disrupting the arrangement of parallel fibers, shifting the crossing positions of intersecting fiber bundles, and partially destroying the structure of the fibers, leading to enlarged voids between fibers, increased distances between fiber bundles, and fuzzing due to partial fiber breakage, which increases the bulkiness of the fabric and improves the texture of the fabric.

[0039] The term "stretching" refers to the formation of minute embossed residual strain in the non-stretchable fabric M by repeatedly stretching and contracting the fabric M. The minute embossed residual strain has the effect of improving the bulkiness of the non-stretchable fabric M. Rubbing refers to the process of fluffing the fibers of fabric M. It is also called raising. The fluffing of the fibers gives the fabric a good texture.

[0040] The fibers constituting the fabric M are not particularly limited, but examples thereof include natural fibers such as cotton, linen, wool, and silk; synthetic fibers such as polypropylene, polyester, acetate, triacetate, polyamide, and polyurethane; biodegradable fibers such as polylactic acid; and blends thereof. Examples of coloring materials for pre-coloring fabrics include water-soluble dyes such as pigments, acid dyes, and basic dyes, disperse dyes used in combination with dispersants, and reactive dyes. When cotton fabrics are used as fabrics, it is preferable to use reactive dyes or pigments suitable for dyeing cotton. When pigments are used, they are preferred because they can be used to color a relatively wide variety of fabrics.

[0041] The texture of the fabric M colored with a pigment is likely to deteriorate due to the presence of a large amount of solid content such as a resin binder. In particular, when ink is applied to the fabric M by a recording method using a textile pigment ink composition containing a urethane resin dispersion having a crosslinkable group and then heat-fixed, the fabric M may become film-like. However, by processing the fabric M with the processing devices 100 and 110 of the present embodiment, the texture can be significantly improved.

[0042] As described above, the processing devices 100, 110 and the printing device 200 of this embodiment can provide the following effects. The processing device 100 is a processing device that performs a texture processing process on printed fabric M, and is equipped with a contact portion having a plurality of protrusions 2b, 3b that contact the fabric M, and a vibration imparting portion 88 that imparts vibration to the contact portion, the contact portion having a first contact portion 2 and a second contact portion 3 that are arranged on either side of the fabric M, the vibration imparting portion 88 having a first drive portion 51 that imparts vibration to the first contact portion 2 and a second drive portion 52 that imparts vibration to the second contact portion 3, and the vibration waveform applied to the first contact portion 2 by the first drive portion 51 and the vibration waveform applied to the second contact portion 3 by the second drive portion 52 are in opposite phases.

[0043] According to this, the first contact portion 2 and the second contact portion 3, which are opposed to each other across the fabric M, are driven in opposite phases, so that the movement of the center of gravity of the entire processing device 100 is canceled out and vibration is reduced. Therefore, it is possible to provide processing devices 100 and 110 that have little vibration and vibration noise and have a high degree of freedom in terms of the installation environment.

[0044] The first drive unit 51 and the second drive unit 52 are each configured as a Scotch yoke mechanism. This allows the drive unit and processing device to be configured with a simple structure. Furthermore, by providing gears 81 and 82 that distribute drive force to the input portions of each drive unit, a structure can be achieved in which two drive units, the first drive unit 51 and the second drive unit 52, can be driven by one drive motor 50. Furthermore, because gear 82 rotates in the opposite direction to the rotation of gear 81, the second drive unit 52 can be driven in the opposite phase to the first drive unit 51 with a simple structure.

[0045] Furthermore, the first driving section 51 and the second driving section 52 operate in synchronization with each other. As a result, the first contact portion 2 and the second contact portion 3 operate to cancel out each other's movements, thereby reducing vibration and vibration noise.

[0046] The printing device 200 includes processing devices 100, 110 and a printing unit 10 that prints on the fabric M. When the processing device 100, which has a first contact portion 2 and a second contact portion 3, is considered to be the first processing device, the printing device 200 further includes processing device 110 as the second processing device that is arranged downstream of the processing device 100 in the conveying direction of the fabric M, and the processing device 110 has a third contact portion 4 and a fourth contact portion 5 that are arranged on either side of the fabric M.

[0047] According to this, the printing device 200 is equipped with processing devices 100 and 110 that have little vibration or vibration noise and have a high degree of freedom in terms of the installation environment. Therefore, it is possible to provide a printing device 200 that has little vibration or vibration noise and has a high degree of freedom in terms of the installation environment.

[0048] Furthermore, the shapes of the protrusions 2b, 3b provided on the first contact portion 2 and the second contact portion 3 are different from the shapes of the protrusions 4b, 5b provided on the third contact portion 4 and the fourth contact portion 5. According to this, the printing device 200 can be provided with the processing device 100 for rough processing and the processing device 110 for finish processing. Therefore, it is possible to provide the printing device 200 that can perform the desired texture processing.

[0049] Embodiment 2 ***Different arrangements of processing equipment*** FIG. 9 is a diagram showing an arrangement of the processing apparatus according to the second embodiment, and corresponds to FIG. In the above embodiment, the processing device 100 is installed so that the fabric M being transported in the horizontal direction is subjected to vibration from above and below by the first contact portion 2 and the second contact portion 3, but this is not limited to this, and the processing device 100 may be installed so that the fabric M being transported in the vertical direction is subjected to vibration from the left and right by the first contact portion 2 and the second contact portion 3. Hereinafter, the same parts as in the above embodiment are assigned the same numbers, and duplicated explanations will be omitted.

[0050] 9, in the installation mode of this embodiment, the fabric M is transported vertically from above to below, and the processing device 100 is installed so that vibrations are applied to the fabric M from the left and right by the first contact portion 2 and the second contact portion 3. In other words, the first drive portion 51 and the second drive portion 52 are arranged side by side facing each other in the horizontal direction. To change the conveying direction of the fabric M, an upper roller 67a and an adjustment roller 67b for lifting, and a lower roller 68a and an adjustment roller 68b are provided. The fabric M is transported horizontally up to the roller pair 61, and then pulled up toward the upper roller 67a, where the transport angle is adjusted by the adjustment roller 67b along the way. The upper roller 67a is suspended by a coil spring 97, which adjusts the tension of the fabric M. As shown in Fig. 9, the fabric M turns around the upper roller 67a and is transported vertically downward.

[0051] After the fabric M is textured in the processing device 100, it rotates around the lower roller 68a, and then the conveyance angle is adjusted by the adjustment roller 68b midway, and it is pulled up towards the roller pair 62. A coil spring 98 is attached to the lower roller 68a, and the tension of the fabric M is adjusted. After passing through the roller pair 62, the fabric M is conveyed horizontally. Although the processing device 100 has been described above as an example, the same can be applied to the processing device 110.

[0052] As described above, the processing devices 100, 110 and the printing device 200 of this embodiment can provide the following effects. According to the processing device 100 of this embodiment, the first drive unit 51 and the second drive unit 52 are arranged horizontally side by side facing each other, and vibrations are applied to the fabric M from the left and right by the first abutment unit 2 and the second abutment unit 3.

[0053] This allows the processing device 100 to be made smaller. In particular, the processing device 100 can be made compact in the width direction when installed. Therefore, when the processing device 100 is mounted on the printing device 200, the printing device 200 can be made smaller. If the processing device 110 is also installed in the same manner as the processing device 100, the printing device 200 can be made even smaller. Furthermore, the first contact portion 2 and the second contact portion 3 are disposed opposite to each other and driven in opposite phases, which cancels out vibrations. In addition, there is no influence of gravity, which further reduces vibrations. Therefore, it is possible to provide processing devices 100, 110 and printing device 200 that are compact, have less vibration and vibration noise, and have a high degree of freedom in terms of the installation environment.

[0054] ***Variations*** This will be explained using Figure 3. If the width of the fabric M is wide, it may be difficult to drive two drive units with the driving force of one drive motor 50. In that case, the first drive unit 51 and the second drive unit 52 may be driven independently. Specifically, without using a transmission mechanism using gears 81 and 82, the first drive unit 51 and the second drive unit 52 are provided with independent drive motors, respectively. A drive signal according to graph 151 and a drive signal according to graph 152 in FIG. 6 are applied to each motor individually. Even with a processing apparatus having this configuration, it is possible to obtain the same effects as those in the above-described embodiments. [Explanation of symbols]
