[0007] The present disclosure will be described below based on embodiments. In each figure, the same reference numerals are used for the same components, and redundant descriptions may be omitted. As used herein, "same," "identical," and "simultaneous" do not mean exactly the same.

[0008] For example, in this specification, when "same," "identical," or "simultaneous" is used, it includes cases where measurement errors are taken into consideration. For example, in this specification, when "same," "identical," or "simultaneous" is used, it includes cases where manufacturing variations of the components are taken into consideration.

[0009] In this specification, the terms "same," "identical," and "simultaneous" include cases where they are the same to the extent that their function is not impaired. Therefore, for example, "the dimensions of both are the same" means that, taking into account measurement errors and manufacturing variations of the components, the difference between the two dimensions is within ±5 percent of the dimension of one, and particularly preferably within ±3 percent.

[0010] In each figure, X, Y, and Z represent three mutually orthogonal spatial axes. In this specification, the directions along these axes are referred to as the X-axis direction, Y-axis direction, and Z-axis direction. When specifying directions, a positive direction is denoted as "+" and a negative direction as "-", and positive and negative signs are used in the direction notation. In each figure, the direction pointed to by the arrow is described as the + direction, and the opposite direction of the arrow is described as the - direction.

[0011] The Z-axis direction indicates the direction of gravity, the +Z direction indicates vertically upward, and the -Z direction indicates vertically downward. A plane containing the X and Y axes is described as the XY plane, a plane containing the X and Z axes is described as the XZ plane, and a plane containing the Y and Z axes is described as the YZ plane. The XY plane is the horizontal plane. The three spatial axes X, Y, and Z, which are not limited to positive and negative directions, are described as the X-axis, Y-axis, and Z-axis.

[0012] The X-axis direction is horizontal along the installation surface, which is the horizontal plane on which the recording device 1 is installed. The X-axis direction is the width direction of the fabric P that is conveyed by the recording device 1. The Y-axis direction is horizontal along the installation surface on which the recording device 1 is installed.

[0013] The Z-axis direction is the normal direction to the mounting surface on which the recording device 1 is installed, and is the height direction of the recording device 1. In the following description, the +Z direction may be referred to as "vertically upward," the +Z direction side as "up," the -Z direction as "vertically downward," and the -Z direction side as "down." For convenience of illustration, the size of each component may differ from the actual size.

[0014] In the embodiments described below, a recording device 1 used for digital printing of fabric P will be illustrated and explained with reference to the drawings. Note that the use of the recording device 1 in this disclosure is not limited to printing.

[0015] In the transport path of the fabric P, which is the recording medium, after it is unrolled from the raw material, printed, and wound into a roll, the raw material side may be called the upstream, and the side where the fabric P is wound may be called the downstream. The direction in which the fabric P is transported from upstream to downstream is defined as the transport direction.

[0016] As shown in Figure 1, the recording device 1 according to this embodiment comprises a control unit 5, a media transport unit 2, a recording unit 60, a drying unit 70, an operation panel 80, a coating unit 110, a cleaning mechanism 120, and a detection unit 130. The recording device 1 also includes a housing (not shown). Each component of the recording device 1 is supported by a frame F.

[0017] The recording device 1 applies pigment ink or the like to a fabric P to form an image such as a picture, photograph, text, or pattern on the fabric P, thereby producing a printed object. In the explanation of Figure 1, unless otherwise specified, the recording device 1 will be described as viewed from the -X direction.

[0018] The control unit 5 is electrically connected to each component of the recording device 1 and comprehensively controls the operation of each component. As will be described in detail later, the control unit 5 is responsible for controlling, for example, the coating unit 110 and the cleaning mechanism 120.

[0019] The control unit 5 includes hardware such as a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory). The control unit 5 executes a predetermined control program using the CPU. The ROM is a non-volatile storage device that stores the control program executed by the CPU and the data processed by the control program. The RAM constitutes the CPU's work area. The CPU loads the control program read from the ROM, etc., into the RAM and executes the loaded control program.

[0020] The operation panel 80 is also electrically connected to the control unit 5. The operation panel 80 notifies various information to the user of the recording apparatus 1 and accepts various operations and inputs of various settings by the user. The control unit 5 also controls the recording apparatus 1 based on the information input to the operation panel 80. In the following description, the user of the recording apparatus 1 is simply referred to as the user.

[0021] The operation panel 80 is supported by the frame F via a member not shown and is disposed above the recording apparatus 1 and at the end in the +Y direction. The user stands in the +Y direction of the recording apparatus 1 and performs various inputs while visually observing the operation panel 80. The operation panel 80 is, for example, a liquid crystal display of a touch panel type. The operation panel 80 may have a sound emitting device and physical buttons in addition to a display device such as a liquid crystal display. The operation panel 80 is an example of the notification unit in the present disclosure.

[0022] The medium transport unit 2 includes a medium supply unit 10, transport rollers 21, 22, 23, 24, a transport mechanism 30, and a winding unit 40. The medium transport unit 2 transports the fabric P along a transport path from upstream to downstream.

[0023] The medium supply unit 10 has a supply shaft portion 11, a bearing portion 12, and a rotation drive unit not shown. The supply shaft portion 11 is substantially cylindrical and holds the core of the fabric P roll. The bearing portion 12 supports both ends of the supply shaft portion 11 in the direction along the X axis in a detachable and rotatable manner.

[0024] The rotation drive unit is, for example, an electric motor and rotationally drives the supply shaft portion 11. Due to the rotation of the supply shaft portion 11 and the belt rotation roller 32 of the transport mechanism 30 described later, the fabric P is unwound from the roll and sent downstream.

[0025] The fabric P is transported from the medium supply unit 10, passes through the transport roller 21, and the transport direction is changed to be substantially in the +Y direction by the transport roller 22. The fabric P is delivered to the transport mechanism 30 from the substantially -Y direction.

[0026] Examples of fibers used as the material for fabric P include natural fibers, regenerated fibers, and synthetic fibers, which may be in the form of single yarns, double yarns, or blends. Natural fibers include cotton, silk, linen, mohair, wool, and cashmere. Regenerated fibers include rayon and cupro. Synthetic fibers include nylon, polyester, and polyurethane. Fabric P is made by processing the above fibers into a woven or nonwoven fabric. Fabric P may be pre-processed to improve the properties of the fabric product manufactured from the printed fabric P.

[0027] The conveying mechanism 30 includes belt rotating rollers 31 and 32, a conveying belt 33, and a crimping section 50.

[0028] The conveyor belt 33 is located between the transport rollers 22 and 23 and conveys the fabric P. The conveyor belt 33 is an endless belt and is stretched by the belt rotating rollers 31 and 32 in a region that includes a position facing the recording unit 60 in the vertical direction. The conveyor belt 33 has an outer circumferential surface 33a and an inner circumferential surface 33b. The outer circumferential surface 33a and the inner circumferential surface 33b are in a front-back relationship. The fabric P can be placed on the outer circumferential surface 33a.

[0029] The conveyor belt 33 has an adhesive layer Ad (see Figure 2). The adhesive layer Ad has adhesive force to the fabric P, and the fabric P can be attached to it. The adhesive layer Ad is provided around the entire circumference of the outer surface 33a. With the fabric P attached to the adhesive layer Ad, the conveyor belt 33 is rotated counterclockwise by the belt rotating rollers 31 and 32. As a result, the fabric P is conveyed in the conveying direction. The conveying direction of the fabric P on the conveyor belt 33 is the +Y direction.

[0030] The width of the conveyor belt 33, which is the dimension along the X-axis, is wider than the width of the fabric P. The width direction of the conveyor belt 33 is the direction intersecting the conveying direction. In this embodiment, the width direction of the conveyor belt 33 is the direction along the X-axis. Hereinafter, the width direction of the conveyor belt 33 may simply be referred to as the width direction.

[0031] The belt rotating rollers 31 and 32 are substantially cylindrical rotating members and form a pair. Each of the belt rotating rollers 31 and 32 is rotatable on an axis of rotation along the X-axis. The belt rotating rollers 31 and 32 are arranged opposite each other in the direction along the Y-axis. The belt rotating roller 31 is located upstream of the conveying mechanism 30 and is positioned near the transport roller 22 in the +Y direction. The belt rotating roller 32 is located downstream of the conveying mechanism 30 and is positioned near the transport roller 23 in the -Y direction. A support member for supporting the conveying belt 33 may be positioned between the belt rotating rollers 31 and 32.

[0032] The belt rotating roller 31 is a driven roller that rotates counterclockwise when the rotation of the belt rotating roller 32 is transmitted to it via the conveyor belt 33. The belt rotating roller 31 is rotatably supported by a roller support (not shown).

[0033] The belt rotating roller 32 is driven to rotate counterclockwise by a drive motor (not shown). The drive motor is controlled by the control unit 5. The belt rotating roller 32 is rotatably supported by the roller support unit 39.

[0034] The fabric P is transferred from the transport roller 22 to the conveying mechanism 30 and placed on the outer surface 33a of the conveying belt 33 above the belt rotating roller 31. At this time, the fabric P does not need to be in close contact with the outer surface 33a.

[0035] The outer circumferential surface 33a supports the fabric P from below. The inner circumferential surface 33b is in contact with the belt rotating roller 31 and the belt rotating roller 32. The frictional force between the inner circumferential surface 33b and the belt rotating roller 32 drives the conveyor belt 33 to rotate. The frictional force between the inner circumferential surface 33b and the belt rotating roller 31 causes the belt rotating roller 31 to move.

[0036] In the direction along the X-axis, which is the width direction of the conveyor belt 33, the width of the adhesive layer Ad on the outer surface 33a is approximately equal to the width of the conveyor belt 33. The path of the conveyor belt 33 from the belt rotating roller 31 to the belt rotating roller 32 is the conveying path of the fabric P. The path of the conveyor belt 33 that returns to the belt rotating roller 31 after being folded back at the belt rotating roller 32 is the non-conveying path. The outer surface 33a faces upward in the conveying path and downward in the non-conveying path.

[0037] The adhesive layer Ad on the outer surface 33a adheres to the fabric P by adhesive force. The adhesive layer Ad includes an adhesive material having adhesive properties, such as silicone resin, acrylic resin, or urethane resin. In the recording device 1, acrylic resin is used as the base material for the adhesive layer Ad. Examples of acrylic resins include polybutyl acrylate.

[0038] The crimping section 50 is positioned near the belt rotating roller 31 in the +Y direction. The crimping section 50 comprises a pressing roller 51, a pair of support sections 53, a heating section 54, and a pair of drive sections (not shown). The crimping section 50 presses the fabric P against the adhesive layer Ad of the conveyor belt 33, thereby attaching the fabric P to the adhesive layer Ad.

[0039] The press roller 51 is a roughly cylindrical rotating member. The press roller 51 has its axis of rotation along the X-axis and is positioned above the conveyor belt 33. The support parts 53 are positioned at both ends of the press roller 51 in the direction along the X-axis. The press roller 51 is rotatably supported by the pair of support parts 53. Each of the pair of support parts 53 is supported by the drive unit. In the direction along the X-axis, the length of the press roller 51 is approximately equal to the width of the conveyor belt 33.

[0040] One of the drive units is positioned further in the -X direction relative to the support unit 53 that supports the -X end of the press roller 51. The other of the drive unit is positioned further in the +X direction relative to the support unit 53 that supports the +X end of the press roller 51.

[0041] The pair of drive units move vertically while supporting the pair of support units 53 by a drive motor (not shown). As a result, the pressing roller 51 can be displaced vertically while being supported by the support units 53. This allows for adjustment of the strength of the pressing force applied by the pressing roller 51 when it presses the fabric P against the adhesive layer Ad on the outer surface 33a.

[0042] Although not shown in the diagram, the pair of drive units reciprocate along the Y-axis while supporting the pair of support units 53, driven by the guide member and the drive motor. Therefore, the pressing roller 51 is supported by the support units 53 and can reciprocate along the Y-axis.

[0043] The heating unit 54 heats the conveyor belt 33. The heating unit 54 is positioned below the press roller 51 via the conveyor belt 33. The upper surface of the heating unit 54 is formed to be substantially flat and contacts the lower inner circumferential surface 33b of the conveyor belt 33 in the conveying path. The distance of the heating unit 54 along the Y-axis is approximately equal to the distance the press roller 51 reciprocates in the conveying direction and the opposite direction of the conveying direction. The distance of the heating unit 54 along the X-axis is approximately equal to the width of the conveyor belt 33 along the X-axis.

[0044] The heating unit 54 is, for example, an electric heater. Heating by the heating unit 54 heats the adhesive layer Ad on the outer surface 33a of the conveyor belt 33. Heating increases the flexibility of the adhesive layer Ad, increasing its adhesive force to the fabric P. The heating temperature by the heating unit 54 is, for example, 35°C to 60°C on the upper surface of the heating unit 54.

[0045] In the crimping section 50, the fabric P is placed on the upper surface of the heating section 54 via the conveyor belt 33. The heating section 54 heats the conveyor belt 33, and the pressing roller 51 presses the fabric P against the adhesive layer Ad from above. In parallel with this, the pressing roller 51 rotates and moves back and forth in the +Y and -Y directions. The fabric P and the conveyor belt 33 are sandwiched and pressed between the upper surface of the heating section 54 and the pressing roller 51, causing the fabric P and its outer surface 33a to be in close contact.

[0046] The fabric P is conveyed in the +Y direction while in close contact with the conveyor belt 33 after passing through the crimping section 50. Alternatively, the pressing roller 51 may be equipped with a function to heat the conveyor belt 33 instead of the heating section 54. Depending on the type of fabric P and the characteristics of the adhesive layer Ad, the heating section 54 may be omitted.

[0047] The following heat roller system is an example of a configuration in which the pressing roller 51 has the function of heating the conveyor belt 33. The heat roller system comprises a support plate having substantially the same shape as the heating unit 54, a heat roller having the same shape as the pressing roller 51, a pair of support units 53, and a pair of drive units. In other words, the heat roller system operates similarly to the pressing unit 50, except that the heat roller takes over the heating function of the heating unit 54.

[0048] The recording unit 60 is positioned in the middle of the Y-axis direction of the conveyor belt 33, facing the outer surface 33a and the fabric P in the vertical direction. The recording unit 60 discharges pigment ink or the like onto the fabric P being conveyed on the conveyor belt 33, thereby recording the image. This prints the image onto the fabric P. The recording unit 60 includes an inkjet head, an ejection unit 61, a carriage 62, and a guide rail 63.

[0049] The guide rail 63 is a structural member that extends along the X-axis and is positioned above the conveying mechanism 30. The guide rail 63 supports the carriage 62 so that it can move in the direction along the X-axis. Supported by the guide rail 63, the carriage 62 reciprocates in the direction along the X-axis by the drive of a drive motor (not shown). The discharge unit 61 is attached to the carriage 62 and reciprocates together with the carriage 62 in the direction along the X-axis relative to the conveying belt 33.

[0050] The dispensing unit 61 dispenses pigment ink and functional liquids onto the fabric P, which is placed on the outer surface 33a and transported. The dispensing unit 61 has a nozzle surface (not shown) facing downwards. The nozzle surface of the dispensing unit 61, which is attached to the carriage 62, faces the transport belt 33 and the fabric P in the vertical direction.

[0051] Multiple nozzle rows are arranged on the nozzle surface. Each of the multiple nozzle rows consists of multiple nozzles. Each of the multiple nozzle rows individually dispenses multiple types of pigment inks exhibiting colors such as cyan, magenta, yellow, and black, as well as functional liquids, onto the fabric P. Examples of pigment inks include water-based inks and non-water-based inks. In this embodiment, water-based pigment inks are used.

[0052] In the discharge section 61, a piezoelectric element is used as the actuator, which is the driving means. The driving means is not limited to this. For example, an electromechanical conversion element that displaces a diaphragm acting as an actuator by electrostatic attraction, or an electrothermal conversion element that discharges ink as droplets by generating bubbles through heating may be used as the driving means.

[0053] Although not shown in the diagram, the pigment ink and functional liquid are supplied from their respective liquid tanks to the discharge unit 61 via liquid piping. The pigment ink and functional liquid discharged from the discharge unit 61 adhere to the upward-facing surface of the fabric P.

[0054] The recording device 1 transports the fabric P in the +Y direction by the transport belt 33 while the ejection unit 61 reciprocates along the X-axis. At this time, pigment ink or the like is ejected from the ejection unit 61 onto the fabric P at a predetermined timing. As a result, a desired image or the like is formed on the fabric P.

[0055] The functional liquid is specifically a softener or pretreatment liquid. The functional liquid is dispensed onto the fabric P at a timing that is simultaneous with or preceding the dispensing of the pigment ink.

[0056] A softener has the function of improving the texture of fabric products such as clothing when a printed fabric P is processed into such products. The softener is not particularly limited, and fabric softeners used for clothing can be applied. If the softener contains cationic components, it may react with the pigment ink components to form aggregates. Therefore, it is preferable to avoid contact or mixing of the softener and the pigment ink.

[0057] The pretreatment solution has the function of agglomerating the pigments and resins in the pigment ink on the surface of the fabric P, thereby improving the color development of the printed material. Since the pretreatment solution agglomerates the pigments, it is preferable to avoid contact or mixing of the pretreatment solution with the pigment ink for purposes other than its intended use.

[0058] Other functional liquids besides softeners and pretreatment solutions may be used as functional liquids. Examples of other functional liquids include coating solutions that improve the abrasion resistance and wash fastness of printed fabric P, and penetrating solutions that assist in the penetration of pigment ink into fabric P.

[0059] In the dispensing unit 61, pre-dispensing is performed before dispensing pigment ink and functional liquid onto the fabric P, and in between dispensing operations. Pre-dispensing is performed to suppress drying and solidification of pigment ink and functional liquid at the gas-liquid interface within each nozzle of the dispensing unit 61, and to prevent color mixing after cleaning each nozzle. The execution of pre-dispensing is controlled by the control unit 5. The timing of pre-dispensing, the time interval, and the amount of pigment ink and functional liquid to be pre-dispensed are set appropriately according to the type and characteristics of the pigment ink and functional liquid.

[0060] The printed fabric P is then transported further in the +Y direction from a position opposite the recording unit 60. The fabric P is then separated from the transport belt 33 approximately above the belt rotating roller 32 and handed over to the transport roller 23 downstream of the belt rotating roller 32.

[0061] Each region of the conveyor belt 33 is folded back from the conveying path to the non-conveying path by the belt rotating roller 32, and moves in the -Y direction with the outer surface 33a facing downwards. In other words, in the non-conveying path, the direction of travel of each region of the conveyor belt 33 is in the -Y direction.

[0062] Because the adhesive layer Ad is placed on the outer surface 33a of the conveyor belt 33, and the conveyed fabric P is in close contact with the adhesive layer Ad, foreign matter such as pigment ink, threads from the fabric P, and dust easily adheres to the adhesive layer Ad. If the adhesion of foreign matter to the adhesive layer Ad is significant, the fabric P may be soiled when the conveyor belt 33 circulates and comes into contact with the fabric P again before printing. The adhesion of foreign matter to the adhesive layer Ad may reduce the adhesive strength of the adhesive layer Ad.

[0063] In particular, some of the pigment ink and functional liquid may pass through the fabric P and reach the adhesive layer Ad, where it may form a pigment film on the surface of the adhesive layer Ad. Pigment inks often contain fixing resins to improve their adhesion to the fabric P. These can facilitate the formation of a pigment film in the adhesive layer Ad. Using a pretreatment liquid as a functional liquid may promote pigment aggregation, leading to increased pigment film formation.

[0064] When pigment film formation or dirt accumulation becomes significant, the adhesive strength of the adhesive layer Ad decreases, which may hinder the transport of the fabric P. In such cases, maintenance work such as reapplying the adhesive layer Ad or replacing the transport belt 33 is performed. Since maintenance work such as reapplying the adhesive layer Ad is performed by stopping the operation of the recording device 1, it has been a factor in reducing the operating rate of the recording device 1. In contrast, the recording device 1 of this embodiment removes dirt from the adhesive layer Ad by the coating section 110 and the cleaning mechanism 120, thereby reducing the frequency of maintenance work.

[0065] The coating unit 110 and the cleaning mechanism 120 are positioned below the conveyor belt 33 in the non-conveyor path. In the direction of travel of each region of the conveyor belt 33 in the non-conveyor path, the cleaning mechanism 120 is positioned in the -Y direction, ahead of the coating unit 110. Details of the configuration and function of the coating unit 110 and the cleaning mechanism 120 will be described later.

[0066] Furthermore, in the following explanation, when the cleaning mechanism 120 is positioned relative to the coating section 110 as described above, the cleaning mechanism 120 may be positioned "downstream" of the coating section 110 in the direction of rotation of the conveyor belt 33. In the following explanation, when the coating section 110 is positioned in the +Y direction of the cleaning mechanism 120 as described above, the coating section 110 may be positioned "upstream" of the cleaning mechanism 120 in the direction of rotation of the conveyor belt 33.

[0067] In the non-conveying path of the conveyor belt 33, a detection unit 130 is provided between the cleaning mechanism 120 and the belt rotating roller 31. The detection unit 130 detects the adhesive force of the adhesive layer Ad of the conveyor belt 33. The detection unit 130 is electrically connected to the control unit 5. The adhesive force information detected by the detection unit 130 is transmitted to the control unit 5. The detection unit 130 makes it possible to monitor the adhesive force of the adhesive layer Ad, or in other words, the degree of contamination of the adhesive layer Ad.

[0068] A probe tack method adhesive strength measuring instrument can be used as the detection unit 130. The placement of the detection unit 130 is not limited to between the cleaning mechanism 120 and the belt rotating roller 31.

[0069] The detection unit 130 is not limited to an adhesion strength meter. For example, the detection unit 130 may be a mechanism that calculates adhesion strength from the peeling angle of the fabric P peeled off by the belt rotating roller 32. Alternatively, the detection unit 130 may be a mechanism that calculates adhesion strength from the rotational resistance of the drive motor that rotates the belt rotating roller 32.

[0070] Alternatively, the detection unit 130 may be a mechanism that calculates the adhesive force from the change in the position of the surface side of the adhesive layer Ad. As the formation of a pigment film or the adhesion of dirt progresses on the adhesive layer Ad, the position of the surface side of the adhesive layer Ad changes by the thickness of the pigment film and dirt.

[0071] For example, suppose the position of the surface side of the adhesive layer Ad on the conveyor belt 33 is measured at a position between the cleaning mechanism 120 and the belt rotating roller 31, within the non-conveying path of the conveyor belt 33. In this case, as pigment film formation or dirt adhesion progresses on the adhesive layer Ad, the position of the surface side of the adhesive layer Ad on the conveyor belt 33 will be displaced in the -Z direction. As a result, the degree of decrease in the adhesive strength of the adhesive layer Ad can be estimated based on the amount of displacement of the surface side of the adhesive layer Ad on the conveyor belt 33 in the -Z direction. Therefore, it becomes possible to estimate the adhesive strength from the change in the position of the surface side of the adhesive layer Ad on the conveyor belt 33.

[0072] As a sensor for measuring the position of the surface side of the adhesive layer Ad on the conveyor belt 33, for example, a reflective photosensor can be used. In this case, the sensor of the detection unit 130 is positioned opposite the adhesive layer Ad at a distance from it.

[0073] Each region of the conveyor belt 33 is folded back from the non-conveyor path to the conveyor path by the belt rotating roller 31, and moves in the +Y direction with its outer surface 33a facing upward. In this way, the conveyor belt 33 rotates counterclockwise.

[0074] The transport roller 23 separates the printed fabric P from the conveyor belt 33. The fabric P separated from the conveyor belt 33 is transported in approximately the +Y direction, and the transport roller 23 changes the transport direction to approximately downward. The transport rollers 23 and 24 relay the fabric P to the winding section 40.

[0075] A drying section 70 is positioned between the transport rollers 23 and 24. The drying section 70 dries the pigment ink and functional liquid adhering to the fabric P. The drying section 70 includes, for example, an infrared heater. The infrared rays emitted by the infrared heater cause volatile components contained in the pigment ink and functional liquid adhering to the fabric P to evaporate. As a result, the droplets of pigment ink and functional liquid dry, making it possible to wind the fabric P in the winding section 40. The fabric P proceeds to the winding section 40 via the transport rollers 24.

[0076] The winding unit 40 is positioned downstream and below the transport roller 24. The winding unit 40 collects the printed material, which is the printed fabric P. The winding unit 40 has a winding shaft 41, a bearing 42, and a rotational drive unit (not shown). The winding shaft 41 is substantially cylindrical and winds the printed material into a roll.

[0077] The bearing section 42 rotatably supports both ends of the winding shaft section 41 in the direction along the X axis. The winding shaft section 41 is detachable from the bearing section 42. The rotational drive section rotates the winding shaft section 41 counterclockwise. The rotational drive section rotates the winding shaft section 41, and the material to be printed is wound up. As a result, the printing material is produced in the recording device 1.

[0078] As shown in Figure 2, the coating unit 110 and the cleaning mechanism 120 are positioned below the conveyor belt 33 in the non-conveyor path and face the adhesive layer Ad on the outer surface 33a in the vertical direction. In Figure 2, the conveyor belt 33 in the non-conveyor path is shown by a dashed line.

[0079] The coating unit 110 and the cleaning mechanism 120 are arranged side by side along the Y-axis. The coating unit 110 is located in the +Y direction relative to the cleaning mechanism 120. In other words, the coating unit 110 is located upstream of the cleaning mechanism 120 in the rotational direction of the conveyor belt 33.

[0080] As a result, each region of the conveyor belt 33 passes through the non-conveyor path, first to a position corresponding to the coating section 110, and then to a position corresponding to the cleaning mechanism 120. The coating section 110 applies the first cleaning solution to the adhesive layer Ad. The cleaning mechanism 120 cleans the adhesive layer Ad with the second cleaning solution.

[0081] The coating section 110 includes a first contact section 111 as a coating member, a first cleaning liquid tank 113, a standard section 117, a first displacement section 116, and a discharge section 119. The first cleaning liquid tank 113 is equipped with a storage tank 112, a liquid level sensor 114, a first supply section 115, a pressing member 142, and a circulation mechanism 118.

[0082] The first cleaning fluid tank 113 has a bathtub shape with an open top. The first cleaning fluid tank 113 stores the first cleaning fluid and applies the first cleaning fluid to the first contact portion 111. The first cleaning fluid tank 113 is positioned below the first contact portion 111.

[0083] The first cleaning solution is collected at the bottom of the first cleaning solution tank 113. A portion of the lower part of the first contact portion 111 is immersed in the first cleaning solution stored in the first cleaning solution tank 113. In the direction along the X axis, the width of the first cleaning solution tank 113 is greater than the width of the first contact portion 111.

[0084] The first cleaning solution has the property of swelling the adhesive layer Ad. The first cleaning solution is, for example, an organic solvent, and is selected according to the material of the adhesive layer Ad and the type of pigment ink applied to the recording device 1. By swelling the adhesive layer Ad, the first cleaning solution lifts and makes it easier to remove pigment films and dirt adhering to the surface of the adhesive layer Ad.

[0085] The first washing solution is not particularly limited, but examples include alcohol-based or glycol ether-based organic solvents such as (2-methoxyethoxy)propanol (also known as dipropylene glycol monomethyl ether), 2-butoxyethanol, ethoxylated propoxylated alcohol (C=16-18), 3-methoxy-3-methylbutanol, and (R)-4-isopropenyl-1-methylcyclohexa-1-ene.

[0086] The first cleaning solution may contain additives such as water and an antifoaming agent in addition to the organic solvent mentioned above. Preferably, the first cleaning solution does not contain surfactants. This suppresses foaming caused by the first cleaning solution.

[0087] The storage tank 112 is a source of the first cleaning fluid and is a liquid storage container that holds the first cleaning fluid. The storage tank 112 is, for example, a resin tank. The storage tank 112 has a lid (not shown), and by opening the lid, the first cleaning fluid can be supplied to the storage tank 112. By closing the lid, the storage tank 112 is sealed.

[0088] When replenishing the first cleaning solution in the first cleaning solution tank 113, the user only needs to replenish the first cleaning solution in the storage tank 112, thus improving user convenience. Since the storage tank 112 functions as a buffer tank, it is possible to replenish the first cleaning solution in the storage tank 112 while consuming it in the application section 110.

[0089] The first supply unit 115 supplies the first cleaning fluid from the storage tank 112 to the first cleaning fluid tank 113. The first supply unit 115 includes a liquid transfer pump 115a, an opening / closing unit 115b, and a supply pipe 115c. The inside of the storage tank 112 and the inside of the first cleaning fluid tank 113 are connected by the supply pipe 115c.

[0090] In the middle of the supply pipe 115c, a liquid transfer pump 115a is positioned closer to the storage tank 112, and an opening / closing section 115b is positioned closer to the first cleaning liquid tank 113. The first cleaning liquid flows through the supply pipe 115c in the order of storage tank 112, liquid transfer pump 115a, and opening / closing section 115b.

[0091] The liquid transfer pump 115a sends the first cleaning liquid contained in the storage tank 112 to the opening / closing section 115b. A liquid pump such as a diaphragm pump or rotary pump can be used for the liquid transfer pump 115a.

[0092] The opening / closing section 115b changes the amount of the first cleaning fluid supplied to the first cleaning fluid tank 113. The first cleaning fluid, whose supply amount has been adjusted by the opening / closing section 115b, is supplied to the first cleaning fluid tank 113 via the supply pipe 115c.

[0093] A valve (not shown) within the opening / closing section 115b can be arbitrarily adjusted to change its opening degree between fully open and fully closed. The opening degree of the valve in the opening / closing section 115b is controlled by the control unit 5. That is, the control unit 5 controls the opening / closing section 115b to adjust the amount of first cleaning fluid supplied to the first cleaning fluid tank 113.

[0094] The control unit 5 controls the opening / closing unit 115b, improving user convenience compared to when the user manually adjusts the supply amount. The valve of the opening / closing unit 115b can be a valve mechanism such as an electromagnetic valve.

[0095] The supply pipe 115c is connected to the side wall of the first cleaning fluid tank 113 in the +Y direction. The first cleaning fluid flows along the side wall of the first cleaning fluid tank 113 in the +Y direction and accumulates at the bottom of the first cleaning fluid tank 113. Note that the arrangement of the components of the first supply unit 115 described above is just an example and is not limited to that.

[0096] The regulating portion 117 defines the volume of the first cleaning fluid stored in the first cleaning fluid tank 113. The regulating portion 117 is positioned at the bottom of the first cleaning fluid tank 113, closer to the -Y direction. The regulating portion 117 is a plate-shaped partition member.

[0097] The regulating portion 117 protrudes upward from the bottom of the first cleaning fluid tank 113 along the XZ plane. The first cleaning fluid is stored in the region partitioned by the side walls and bottom of the first cleaning fluid tank 113 and the regulating portion 117.

[0098] In Figure 2, the above region is shown as hatched with diagonal lines. Figure 2 shows the state in which the liquid level of the first cleaning liquid stored in the first cleaning liquid tank 113 is at liquid level Lv. Liquid level Lv is the liquid level when the first contact part 111 is immersed in the first cleaning liquid stored in the first cleaning liquid tank 113 and the tank is full of the first cleaning liquid.

[0099] If more of the first cleaning solution is supplied when it is at the liquid level Lv, the first cleaning solution will overflow the specified section 117 and spill out in the -Y direction. The spilled first cleaning solution is discharged outside the coating section 110 by the discharge section 119. The first cleaning solution discharged from the discharge section 119 may be stored in a drain tank (not shown) or recycled for reuse.

[0100] The liquid level sensor 114 detects the height of the liquid level of the first cleaning liquid stored in the first cleaning liquid tank 113, i.e., the amount stored. The liquid level sensor 114 is, for example, a contact-type or non-contact-type liquid level sensor.

[0101] The liquid level sensor 114 detects the vertical position of the liquid surface, including the liquid level Lv, that is, the amount of first cleaning fluid stored in the first cleaning fluid tank 113. The liquid level sensor 114 is electrically connected to the control unit 5. Hereinafter, the amount of first cleaning fluid stored in the first cleaning fluid tank 113 will also be simply referred to as the amount stored in the first cleaning fluid tank 113.

[0102] The liquid level sensor 114 detects the amount of liquid stored in the first cleaning liquid tank 113, and this information is transmitted to the control unit 5. The control unit 5 can adjust the amount of liquid stored in the first cleaning liquid tank 113 by controlling the first supply unit 115 and the circulation mechanism 118, which will be described later.

[0103] When the coating unit 110 is operated to apply the first cleaning solution to the adhesive layer Ad, the amount of liquid stored in the first cleaning solution tank 113 is preferably such that the first cleaning solution does not overflow, and more preferably it is at the liquid level Lv.

[0104] By operating the coating unit 110 without causing the first cleaning solution to overflow, the consumption of the first cleaning solution can be suppressed. However, if the pigment film or dirt adhering to the adhesive layer Ad is significant, the control unit 5 may operate the coating unit 110 while causing the first cleaning solution to overflow by supplying the first cleaning solution from the storage tank 112 to the first cleaning solution tank 113.

[0105] The composition of the first cleaning solution stored in the first cleaning solution tank 113, that is, the concentration of the first cleaning solution, is adjusted in the storage tank 112 by adding water or the like to the first cleaning solution. Alternatively, the first cleaning solution may be used in its undiluted form in the first cleaning solution tank 113 without dilution with water or the like.

[0106] The first contact portion 111 has a substantially cylindrical shape with its central axis aligned with the X-axis. The first contact portion 111 is made of a liquid-absorbing material capable of holding liquid, such as a sponge material. In the direction along the X-axis, the width of the first contact portion 111 is equal to or greater than the width of the adhesive layer Ad.

[0107] The first contact portion 111 is detachably supported by the first mounting portion 141. The first mounting portion 141 is provided in the first cleaning fluid tank 113. The first mounting portion 141 is located in the +Y direction of the cleaning portion 121, which will be described later.

[0108] In other words, the first mounting portion 141 is located upstream of the cleaning portion 121 in the rotational direction of the conveyor belt 33. A drive motor (not shown) is connected to the first contact portion 111 attached to the first mounting portion 141.

[0109] In this embodiment, the first contact portion 111 and the second contact portion 133, which will be described later, have the same shape and configuration. Therefore, the second contact portion 133 is detachable from the first mounting portion 141, and when attached to the first mounting portion 141, it functions as a coating member in the same way as the first contact portion 111.

[0110] The first contact portion 111 or the second contact portion 133 is supported by the first mounting portion 141, so that a portion of its lower part is immersed in the first cleaning fluid in the first cleaning fluid tank 113. As a result, the first contact portion 111 or the second contact portion 133 absorbs and retains the first cleaning fluid. When the drive motor is rotationally driven, the first contact portion 111 or the second contact portion 133 rotates counterclockwise around their respective central axes when mounted on the first mounting portion 141.

[0111] The first contact portion 111 or the second contact portion 133, which is attached to the first mounting portion 141, functions as an application member that applies the first cleaning liquid to the adhesive layer Ad by rotating while containing the first cleaning liquid and coming into contact with the adhesive layer Ad.

[0112] As described above, in the direction along the X-axis, the widths of the first contact portion 111 and the second contact portion 133 are equal to or greater than the width of the adhesive layer Ad. Therefore, the first cleaning solution is applied to the entire surface of the adhesive layer Ad in the width direction by contact with the first contact portion 111 or the second contact portion 133. The application of the first cleaning solution causes the adhesive layer Ad to swell, making it easier to lift and remove any pigment film or dirt adhering to the adhesive layer Ad.

[0113] Furthermore, foreign matter such as a pigment film may adhere to the first contact portion 111 or the second contact portion 133 due to contact with the adhesive layer Ad. The foreign matter such as a pigment film adhering to the first contact portion 111 or the second contact portion 133 is transferred to the first cleaning solution tank 113 by immersion of the first contact portion 111 or the second contact portion 133 in the first cleaning solution.

[0114] More specifically, the area of ​​the first contact portion 111 or the second contact portion 133 that comes into contact with the adhesive layer Ad is immersed in the first cleaning solution in the first cleaning solution tank 113 by rotating after contact with the adhesive layer Ad. As a result, any foreign matter adhering to the first contact portion 111 or the second contact portion 133 is transferred to the first cleaning solution tank 113. This cleans the first contact portion 111 or the second contact portion 133.

[0115] Furthermore, in this embodiment, a pressing member 142 is provided in the first cleaning fluid tank 113 at a position where it can press against the circumferential surface of the first contact portion 111 or the second contact portion 133, which is mounted on the first mounting portion 141. The pressing member 142 has a cylindrical shape that extends in the X-axis direction so that its circumferential surface can contact the circumferential surface of the first contact portion 111 or the second contact portion 133. In the X-axis direction, the width of the circumferential surface of the pressing member 142 is equal to or greater than the width of the first contact portion 111 and the second contact portion 133.

[0116] The pressing member 142 is positioned to be able to contact the circumferential surface of the first contact portion 111 or the second contact portion 133, which is immersed in the first cleaning fluid. The pressing member 142 is provided in the first cleaning fluid tank 113 so as to be able to rotate in accordance with the rotation of the first contact portion 111 or the second contact portion 133.

[0117] By providing the pressing member 142 in the first cleaning fluid tank 113, the first contact portion 111 or the second contact portion 133, which is immersed in the first cleaning fluid in the first cleaning fluid tank 113, is pressed against the pressing member 142 while rotating. This allows for more efficient removal of foreign matter adhering to the first contact portion 111 or the second contact portion 133.

[0118] In this embodiment, a first contact portion 111, which is a contact-type sponge member, is exemplified as the coating member that applies the first cleaning solution to the adhesive layer Ad, but the embodiment is not limited to this. For example, the coating portion 110 may use a substantially cylindrical brush or the like, which has a similar shape to the first contact portion 111 as a coating member, to apply the first cleaning solution to the entire area of ​​the adhesive layer Ad in the width direction.

[0119] In this embodiment, the first cleaning solution is applied to the first contact portion 111 or the second contact portion 133 by immersion in the first cleaning solution in the first cleaning solution tank 113, but the embodiment is not limited to this. For example, the coating portion 110 may have the first cleaning solution applied to the first contact portion 111 or the second contact portion 133 by a spraying device, a dropping device, or the like. In this case, the first cleaning solution is applied to the first contact portion 111 or the second contact portion 133 by dropping, spraying, or the like.

[0120] The circulation mechanism 118 circulates the first cleaning fluid stored in the first cleaning fluid tank 113. The circulation mechanism 118 is connected to the area where the first cleaning fluid is stored at the bottom of the first cleaning fluid tank 113.

[0121] The circulation mechanism 118 includes an opening / closing section 118v, a filter section 118a, a circulation section 118b, and a switching section 118d. In the circulation mechanism 118, the opening / closing section 118v, the filter section 118a, the circulation section 118b, and the switching section 118d are arranged in order of proximity to the first cleaning fluid tank 113. The first cleaning fluid tank 113 and the opening / closing section 118v, the filter section 118a, the circulation section 118b, and the switching section 118d are connected by piping 118c.

[0122] In the piping 118c, an on / off section 118v is provided near the first cleaning fluid tank 113. The on / off section 118v is a valve mechanism that switches between the outflow and cessation of the first cleaning fluid from the first cleaning fluid tank 113 to the circulation mechanism 118.

[0123] The filter section 118a filters the first cleaning liquid that flows from the first cleaning liquid tank 113 into the circulation mechanism 118. Due to contact between the first contact section 111 or the second contact section 133 and the adhesive layer Ad, foreign matter such as pigment film and dust that was attached to the adhesive layer Ad may be mixed into the first cleaning liquid stored in the first cleaning liquid tank 113.

[0124] The filter section 118a removes the aforementioned foreign matter from the first washing solution by filtering it. The filter section 118a can be a mesh filter, filter cloth, nonwoven fabric filter, or the like.

[0125] The circulation unit 118b circulates the first cleaning fluid stored in the first cleaning fluid tank 113. For example, a liquid transfer pump such as a diaphragm pump or a rotary pump can be used as the circulation unit 118b. The circulation unit 118b is driven by the control unit 5, causing the first cleaning fluid stored in the first cleaning fluid tank 113 to circulate.

[0126] The switching unit 118d switches the connection destination of the other end of the piping 118c, one end of which is connected to the first cleaning fluid tank 113, to one of the storage tank 112, the first cleaning fluid tank 113, or the drainage tank. The switching unit 118d is composed of, for example, a switching valve and connecting piping that connects the switching valve to the storage tank 112, the first cleaning fluid tank 113, and the drainage tank. The switching of the connection destination of the other end of the piping 118c by the switching unit 118d is performed by the control unit 5 controlling the switching valve.

[0127] When the circulation unit 118b is driven with the other end of the piping 118c connected to the storage tank 112, the first cleaning fluid stored in the first cleaning fluid tank 113 is returned to the storage tank 112. This makes it possible to reuse the first cleaning fluid discharged from the first cleaning fluid tank 113 via the piping 118c, thereby reducing the consumption of the first cleaning fluid.

[0128] When the circulation unit 118b is driven with the other end of the piping 118c connected to the first cleaning fluid tank 113, the first cleaning fluid stored in the first cleaning fluid tank 113 circulates through the first cleaning fluid tank 113, the piping 118c, and the switching unit 118d. As a result, the first cleaning fluid discharged from the first cleaning fluid tank 113 via the piping 118c is reused, thus reducing the consumption of the first cleaning fluid.

[0129] When the circulation unit 118b is driven while the other end of the piping 118c is connected to the drain tank, the first cleaning fluid stored in the first cleaning fluid tank 113 is discharged into the drain tank. This allows the amount of first cleaning fluid stored in the first cleaning fluid tank 113 to be adjusted to less than full capacity.

[0130] The first displacement unit 116 changes the position of the first cleaning liquid tank 113 of the coating unit 110 relative to the adhesive layer Ad of the conveyor belt 33 between a contact position and a separated position. The first cleaning liquid tank 113 is provided with the first mounting unit 141 described above, which supports the first contact unit 111.

[0131] As a result, at the contact position of the first cleaning fluid tank 113 shown in Figure 2, the first contact portion 111 (see Figure 2) or the second contact portion 133 (not shown), supported by the first mounting portion 141, is in a contact position that contacts the adhesive layer Ad. At the separated position of the first cleaning fluid tank 113, the first contact portion 111 or the second contact portion 133, supported by the first mounting portion 141, is in a non-contact position that is away from the adhesive layer Ad.

[0132] In other words, the first mounting portion 141 provided on the first cleaning fluid tank 113 allows the second contact portion 133 to be displaced between a contact position in contact with the adhesive layer Ad and a non-contact position not in contact with the adhesive layer Ad. At the contact position with the first cleaning fluid tank 113, the first cleaning fluid is applied to the adhesive layer Ad, and at the separated position with respect to the first cleaning fluid tank 113, the first cleaning fluid is not applied to the adhesive layer Ad.

[0133] The first displacement unit 116 is located below the first cleaning fluid tank 113. The first displacement unit 116 is electrically connected to the control unit 5. Although not shown in the figures, the first displacement unit 116 includes an actuator or an electric motor.

[0134] The first displacement unit 116 is controlled by the control unit 5 to displace the first cleaning fluid tank 113, the first contact portion 111 or the second contact portion 133, the first mounting portion 141, etc., in the Z-axis direction. The first displacement unit 116 can move the first cleaning fluid tank 113 from the contact position shown in Figure 2 to a separated position (not shown) located in the -Z direction of the contact position.

[0135] For example, when a user attaches or detaches the first contact portion 111 or the second contact portion 133 to the first mounting portion 141, the first displacement portion 116 moves the first cleaning fluid tank 113 to a separated position. This makes it easier to attach or detach the first contact portion 111 or the second contact portion 133 to the first mounting portion 141.

[0136] For example, if the pigment film or dirt adhering to the adhesive layer Ad is minimal, the first displacement unit 116 moves the first cleaning fluid tank 113 to a separated position. This reduces the consumption of the first cleaning fluid and the wear of the first contact unit 111.

[0137] As the conveyor belt 33 rotates, the area to which the first cleaning solution has been applied by the coating unit 110 moves toward the cleaning mechanism 120, which is downstream of the first contact unit 111 or the second contact unit 133 supported by the first mounting unit 141. In the adhesive layer Ad, swelling progresses between the time the first cleaning solution is applied and when it reaches the cleaning mechanism 120.

[0138] The cleaning mechanism 120 includes a cleaning section 121, a second cleaning liquid tank 123, a standardization section 127, a wiping section 131, a second contact section 133 as a wiping section, a second displacement section 126, and a discharge section 129. A second supply section 125 is attached to the second cleaning liquid tank 123.

[0139] In the direction along the Y-axis, it is preferable that the distance between the coating section 110 and the cleaning mechanism 120 be as far apart as possible. When the above distance is relatively far apart, sufficient time is ensured for the adhesive layer Ad to swell due to the first cleaning liquid applied by the coating section 110.

[0140] The cleaning section 121, the wiping section 131, and the second contact section 133 are positioned to contact the adhesive layer Ad of the conveyor belt 33 and are arranged in the above order toward the -Y direction, which is downstream in the rotational direction of the conveyor belt 33. The adhesive layer Ad slides against these components in the order of cleaning section 121, wiping section 131, and second contact section 133.

[0141] The second cleaning fluid tank 123 is bathtub-shaped with an open top and stores a second cleaning fluid for cleaning the adhesive layer Ad. The second cleaning fluid tank 123 is located below the cleaning unit 121. The second cleaning fluid is accumulated at the bottom of the second cleaning fluid tank 123. A portion of the lower part of the cleaning unit 121 is immersed in the second cleaning fluid stored in the second cleaning fluid tank 123.

[0142] In the direction along the X-axis, the width of the second cleaning fluid tank 123 is greater than the width of the cleaning section 121. The second cleaning fluid tank 123 is an example of a cleaning fluid tank capable of storing the second cleaning fluid in which the cleaning section 121 is immersed.

[0143] The second cleaning solution does not have the property of swelling the adhesive layer Ad. The second cleaning solution is, for example, water. Examples of water include pure water such as ion-exchanged water, ultrafiltered water, reverse osmosis water, and distilled water, as well as tap water.

[0144] In this embodiment, tap water is used as the second cleaning solution. The second cleaning solution may contain additives such as disinfectants. From the same viewpoint as the first cleaning solution, it is preferable that the second cleaning solution does not contain surfactants.

[0145] The second supply unit 125 supplies the second cleaning liquid to the second cleaning liquid tank 123 of the cleaning mechanism 120. The second supply unit 125 has a pipe 125a, an opening / closing unit 125b, and a supply pipe 125c. The pipe 125a, the opening / closing unit 125b, and the supply pipe 125c are arranged in the order described above toward the second cleaning liquid tank 123. The second cleaning liquid flows in the second supply unit 125 in the order described above.

[0146] The pipe 125a connects the supply source for the second cleaning fluid to the on / off section 125b. In this embodiment, since tap water is used as the second cleaning fluid, the pipe 125a is connected to a tap water faucet, for example, via a flexible hose. Alternatively, the pipe 125a may be connected to a container similar to the storage tank 112, and the second cleaning fluid, such as tap water, may be supplied from that container.

[0147] The opening / closing unit 125b changes the supply amount of the second cleaning fluid supplied to the second cleaning fluid tank 123. The opening / closing unit 125b is connected to the piping 125a and the supply pipe 125c. The second cleaning fluid, whose supply amount has been adjusted by the opening / closing unit 125b, is supplied to the second cleaning fluid tank 123 via the supply pipe 125c.

[0148] A valve (not shown) within the opening / closing section 125b can be arbitrarily adjusted to change its opening degree between fully open and fully closed. The opening degree of the valve in the opening / closing section 125b is controlled by the control unit 5. That is, the control unit 5 controls the opening / closing section 125b of the second supply unit 125 to adjust the amount of second cleaning fluid supplied to the second cleaning fluid tank 123. The valve in the opening / closing section 125b is fitted with the same valve mechanism as the opening / closing section 115b of the coating unit 110.

[0149] The supply pipe 125c connects the opening / closing section 125b to the second cleaning fluid tank 123. The second cleaning fluid supplied from the supply pipe 125c flows along the side wall in the +Y direction of the second cleaning fluid tank 123 and accumulates at the bottom of the second cleaning fluid tank 123. Note that the arrangement of the components of the second supply section 125 described above is just an example and is not limited to that.

[0150] The regulating section 127 defines the volume of the second cleaning fluid stored in the second cleaning fluid tank 123. The regulating section 127 is positioned at the bottom of the second cleaning fluid tank 123, closer to the -Y direction. The regulating section 127 is a plate-shaped partition member.

[0151] The regulating portion 127 is aligned with the XZ plane and protrudes upward from the bottom of the second cleaning fluid tank 123. The second cleaning fluid is stored in the region demarcated by the side walls and bottom of the second cleaning fluid tank 123 and the regulating portion 127.

[0152] In Figure 2, the above area is shown as hatched with diagonal lines. Figure 2 shows the state in the second cleaning fluid tank 123 where a portion of the lower part of the cleaning unit 121 is submerged in the second cleaning fluid stored therein, and the tank is filled to capacity with the second cleaning fluid.

[0153] If a second cleaning solution is supplied from the above state, the second cleaning solution will overflow the designated section 127 and spill out in the -Y direction. The spilled second cleaning solution will be discharged from the discharge section 129 to the outside of the second cleaning solution tank 123. The second cleaning solution discharged from the discharge section 129 may be stored in a drain tank or the like.

[0154] The second cleaning liquid tank 123 is equipped with a device (not shown) for measuring the height of the liquid level of the second cleaning liquid stored therein. A device similar to the liquid level sensor 114 in the coating section 110 can be used for this purpose.

[0155] The cleaning unit 121 cleans the adhesive layer Ad of the conveyor belt 33. The cleaning unit 121 is a substantially cylindrical brush member with its central axis aligned with the X-axis. In the direction aligned with the X-axis, the width of the cleaning unit 121 is equal to or greater than the width of the adhesive layer Ad.

[0156] Although not shown in the diagram, the second cleaning fluid tank 123 is provided with a support member that rotatably supports the cleaning unit 121, and a drive motor that rotates the cleaning unit 121. The cleaning unit 121 is supported by the support member, so that a portion of its lower part is immersed in the second cleaning fluid in the second cleaning fluid tank 123. As a result, the cleaning unit 121, to which the second cleaning fluid has adhered, is rotated counterclockwise around its central axis by the drive motor.

[0157] The cleaning unit 121 rotates while the second cleaning solution is attached to it and comes into contact with the adhesive layer Ad, scraping off foreign matter such as pigment coatings and dust. As described above, in the direction along the X axis, the width of the cleaning unit 121 is equal to or greater than the width of the adhesive layer Ad, so the cleaning unit 121 comes into contact with the entire area of ​​the adhesive layer Ad in the width direction.

[0158] When the first cleaning solution is applied, the adhesive layer Ad swells, and foreign matter such as pigment coatings and dust is lifted off the surface. The adhesive layer Ad then slides against the cleaning unit 121. This scrapes off and removes foreign matter such as pigment coatings and dust from the adhesive layer Ad. In other words, the cleaning unit 121 cleans the adhesive layer Ad to which the first cleaning solution has been applied.

[0159] Pigment coatings and foreign matter such as dust are transferred from the adhesive layer Ad to the second cleaning liquid tank 123 by the rotation of the cleaning unit 121. Specifically, the area of ​​the cleaning unit 121 that slides against the adhesive layer Ad is immersed in the second cleaning liquid in the second cleaning liquid tank 123 by the rotation after sliding against the adhesive layer Ad. As a result, the foreign matter scraped off from the adhesive layer Ad by the cleaning unit 121 is transferred to the second cleaning liquid tank 123. This cleans the cleaning unit 121. As the conveyor belt 33 rotates, the area of ​​the adhesive layer Ad that slides against the cleaning unit 121 moves toward the wiping unit 131.

[0160] The wiping section 131 slides against the adhesive layer Ad, scraping off the second cleaning liquid and other substances adhering to the adhesive layer Ad. The wiping section 131 is a roughly plate-shaped rubber member. The second cleaning liquid scraped off the surface of the adhesive layer Ad falls downward and is discharged from the discharge section 129. Due to the rotation of the conveyor belt 33, the area of ​​the adhesive layer Ad that has slid against the wiping section 131 moves toward the second contact section 133.

[0161] The second contact portion 133, which acts as a wiping portion, absorbs and removes trace amounts of the second cleaning liquid remaining on the adhesive layer Ad. The second contact portion 133 has a substantially cylindrical shape with its central axis aligned with the X-axis. The second contact portion 133 is composed of a liquid-absorbing material capable of holding liquid, such as a sponge material.

[0162] In the direction along the X-axis, the width of the second contact portion 133 is equal to or greater than the width of the adhesive layer Ad. When the adhesive layer Ad passes over the second contact portion 133, the entire area of ​​the adhesive layer Ad in the direction along the X-axis slides against the second contact portion 133.

[0163] The second contact portion 133 is detachably supported by the second mounting portion 132. The second mounting portion 132 is provided in the second cleaning fluid tank 123. The second mounting portion 132 is located in the -Y direction of the cleaning portion 121 and the wiping portion 131. In other words, the second mounting portion 132, and the second contact portion 133 supported by the second mounting portion 132, are located downstream of the cleaning portion 121 and the wiping portion 131 in the rotational direction of the conveyor belt 33.

[0164] As described above, the second contact portion 133 and the first contact portion 111 have the same shape and configuration. Therefore, the first contact portion 111 is detachable from the second mounting portion 132, just like the second contact portion 133. When attached to the second mounting portion 132, the first contact portion 111 functions as a wiping portion, just like the second contact portion 133.

[0165] A drive motor (not shown) is connected to the second contact portion 133, which is supported by the second mounting portion 132. When the drive motor is driven, the second contact portion 133 rotates counterclockwise around its central axis.

[0166] As the conveyor belt 33 rotates, the area of ​​the adhesive layer Ad that has slid with the second contact portion 133 passes through the detection unit 130 described above and returns from the non-conveyor path to the conveyor path. As a result, the adhesive layer Ad of the conveyor belt 33 is cleaned.

[0167] The second displacement unit 126 changes the position of the second cleaning liquid tank 123 of the cleaning mechanism 120 relative to the adhesive layer Ad of the conveyor belt 33 between a contact position and a separated position. The second cleaning liquid tank 123 is provided with the aforementioned second mounting unit 132 that supports the cleaning unit 121, the wiping unit 131, and the second contact unit 133.

[0168] As a result, at the contact position of the second cleaning liquid tank 123 shown in Figure 2, the cleaning unit 121, the wiping unit 131, and the second contact unit 133 supported by the second mounting unit 132 come into contact with the adhesive layer Ad. This enables cleaning of the adhesive layer Ad by the cleaning mechanism 120 at the contact position of the second cleaning liquid tank 123.

[0169] At the separated position (not shown) of the second cleaning fluid tank 123, the cleaning section 121, the wiping section 131, and the second contact section 133 supported by the second mounting section 132 are separated from the adhesive layer Ad. Therefore, at the separated position of the second cleaning fluid tank 123, cleaning of the adhesive layer Ad by the cleaning mechanism 120 is not performed.

[0170] The second displacement unit 126 is located below the second cleaning fluid tank 123. The second displacement unit 126 is electrically connected to the control unit 5. Although not shown in the figures, the second displacement unit 126 includes an actuator or an electric motor.

[0171] The second displacement unit 126 is controlled by the control unit 5 to displace the second cleaning fluid tank 123 in the Z-axis direction. The second displacement unit 126 is capable of moving the second cleaning fluid tank 123 from a contact position to a separated position located in the -Z direction of the contact position.

[0172] For example, when it is not necessary to clean the adhesive layer Ad, the second displacement unit 126 moves the second cleaning fluid tank 123 to a separated position. This reduces the consumption of the second cleaning fluid and the wear of the cleaning unit 121, the wiping unit 131, and the second contact unit 133.

[0173] For example, when a user attaches or detaches the second contact portion 133 or the first contact portion 111 to or from the second mounting portion 132, the second displacement portion 126 moves the second cleaning fluid tank 123 to a separated position. This makes it easier to attach or detach the second contact portion 133 or the first contact portion 111 to or from the second mounting portion 132.

[0174] Furthermore, during the recording operation in which the recording device 1 performs recording, the adhesive layer Ad is cleaned at least by the cleaning mechanism 120. On the other hand, the application of the first cleaning solution to the adhesive layer Ad by the coating unit 110 is performed as needed.

[0175] For example, if the adhesive layer Ad is clean or if the adhesion of foreign matter such as a pigment film to the adhesive layer Ad is minor, the control unit 5 determines that it is unnecessary to apply the first cleaning solution to the adhesive layer Ad by the coating unit 110.

[0176] In such cases, even during recording, the control unit 5 moves the second cleaning fluid tank 123 to a separated position using the second displacement unit 126, thereby separating the second contact unit 133 from the adhesive layer Ad.

[0177] Next, the control of the coating unit 110 and the cleaning mechanism 120 by the control unit 5 will be explained. The following explanation will refer to Figures 1 and 2.

[0178] The control unit 5 causes the cleaning mechanism 120 to clean the adhesive layer Ad while the recording device 1 is performing a recording operation. Prior to the cleaning of the adhesive layer Ad by the cleaning mechanism 120, the control unit 5 causes the coating unit 110 to apply the first cleaning solution to the adhesive layer Ad.

[0179] The pigment film is formed on the adhesive layer Ad during the recording operation. Therefore, the formation of the pigment film can be suppressed by cleaning the adhesive layer Ad, to which the first cleaning solution has been applied by the coating unit 110 during the recording operation, using the cleaning mechanism 120.

[0180] The control unit 5 causes the cleaning mechanism 120 to clean the adhesive layer Ad during periods other than when the recording device 1 is performing recording operations. Prior to the cleaning of the adhesive layer Ad by the cleaning mechanism 120, the control unit 5 causes the coating unit 110 to apply the first cleaning solution to the adhesive layer Ad. By applying the first cleaning solution and performing cleaning before or after the recording operation, the recording operation can be started with the adhesive layer Ad in a clean state.

[0181] Based on the liquid level sensor 114 detecting that the amount of liquid stored in the first cleaning liquid tank 113 has fallen below a threshold, the control unit 5 prompts the user to replenish the first cleaning liquid in the first cleaning liquid tank 113 via the control panel 80, which is the notification unit. Since the user no longer needs to manage the amount of liquid stored in the first cleaning liquid tank 113, user convenience is improved.

[0182] The method for notifying the decrease in the amount of liquid stored in the first cleaning fluid tank 113 via the operation panel 80 is, for example, by a warning sound, voice, and text display on a liquid crystal display. The recording device 1 may be equipped with an indicator light in a housing (not shown) as a notification unit, and the decrease in the amount of liquid stored in the first cleaning fluid tank 113 may be notified by the illumination of the indicator light.

[0183] The control unit 5 may control the first supply unit 115 to supply the first cleaning liquid to the first cleaning liquid tank 113 based on the liquid level sensor 114 detecting that the amount of liquid stored in the first cleaning liquid tank 113 has fallen below a threshold.

[0184] As a result, the first cleaning solution is automatically supplied to the first cleaning solution tank 113, improving user convenience. The threshold for the amount of liquid stored in the first cleaning solution tank 113, as described above, is, for example, 70% when the amount of liquid stored in the first cleaning solution tank 113 shown in Figure 2 is considered to be 100%.

[0185] Based on the detection unit 130 detecting that the adhesive strength of the adhesive layer Ad has fallen below a threshold, the control unit 5 causes the coating unit 110 to apply the first cleaning solution to the adhesive layer Ad and the cleaning mechanism 120 to clean the adhesive layer Ad.

[0186] In the adhesive layer Ad, as pigment film formation and foreign matter adhesion progress, the adhesive strength gradually decreases. Therefore, depending on the degree of pigment film formation and the amount of foreign matter adhesion, the first cleaning solution is automatically applied to the adhesive layer Ad to perform cleaning.

[0187] This restores the adhesive strength of the adhesive layer Ad, suppresses its deterioration, and further improves the operating rate. Since the first cleaning solution is automatically applied as the adhesive strength decreases, user convenience is improved.

[0188] Based on the detection unit 130 detecting that the adhesive force of the adhesive layer Ad has fallen below a threshold, the control unit 5 controls the first displacement unit 116 to move the first cleaning liquid tank 113 to the contact position. As a result, the first contact unit 111 or the second contact unit 133 attached to the first mounting unit 141 comes into contact with the adhesive layer Ad of the conveyor belt 33. Furthermore, the control unit 5 causes the coating unit 110 to apply the first cleaning liquid to the adhesive layer Ad, and the cleaning mechanism 120 to clean the adhesive layer Ad.

[0189] Based on the detection unit 130 detecting that the adhesive force of the adhesive layer Ad has exceeded a threshold, the control unit 5 controls the first displacement unit 116 to move the first cleaning liquid tank 113 to a separated position. As a result, the first contact unit 111 or the second contact unit 133 attached to the first mounting unit 141 separates from the adhesive layer Ad of the conveyor belt 33. Consequently, the control unit 5 stops the application of the first cleaning liquid to the adhesive layer Ad by the coating unit 110.

[0190] In the adhesive layer Ad, if the adhesive strength decreases due to the formation of a pigment film or the adhesion of foreign matter, the first cleaning solution is automatically applied to the adhesive layer Ad. When the adhesive strength is restored by cleaning the adhesive layer Ad to which the first cleaning solution has been applied, the application of the first cleaning solution to the adhesive layer Ad is automatically stopped.

[0191] These measures improve user convenience and reduce waste of the first cleaning solution. The threshold for the adhesive strength of the adhesive layer Ad mentioned above is, for example, 70% when the initial adhesive strength of the adhesive layer Ad is considered to be 100%.

[0192] The above describes a method for applying the first cleaning solution according to the adhesive strength of the adhesive layer Ad, but it is not limited to this. The control unit 5 may change the application and stopping of the first cleaning solution depending on the operating time of the recording device 1, etc. For example, the following methods can be specifically mentioned.

[0193] First, after a predetermined time has elapsed since the start of the recording operation, the application of the first cleaning solution to the adhesive layer Ad begins. The predetermined time is, for example, 30 minutes. Next, after, for example, 30 minutes have elapsed since the start of the application of the first cleaning solution, the application of the first cleaning solution may be stopped. Alternatively, the application of the first cleaning solution may be continued even after 30 minutes have elapsed.

[0194] Furthermore, the user can choose whether to start and stop the application of the first cleaning solution in accordance with the adhesive strength of the adhesive layer Ad, or in accordance with the elapsed time, at any time before, after, or during the recording operation.

[0195] When the user attaches or detaches the first contact portion 111 or the second contact portion 133 to the first mounting portion 141, the control unit 5 controls the first displacement portion 116 to move the first cleaning fluid tank 113 to a separated position. This makes it easier to attach and detach the first contact portion 111 and the second contact portion 133 to the first mounting portion 141.

[0196] When the user attaches or detaches the second contact portion 133 or the first contact portion 111 to the second mounting portion 132, the control unit 5 controls the second displacement portion 126 to move the second cleaning fluid tank 123 to a separated position. This makes it easier to attach and detach the second contact portion 133 and the first contact portion 111 to the second mounting portion 132.

[0197] As described above, the recording device 1 according to this embodiment can provide the following effects.

[0198] The recording device 1 has an adhesive layer Ad to which a fabric P can be attached, and includes a conveyor belt 33 that conveys the fabric P attached to the adhesive layer Ad by rotating. The recording device 1 includes a recording unit 60 that records on the conveyed fabric P. The recording device 1 includes a cleaning unit 121 that cleans the adhesive layer Ad. The recording device 1 includes a second contact unit 133 that has liquid-absorbing properties. The recording device 1 includes a second mounting unit 132 located downstream of the cleaning unit 121 in the rotational direction of the conveyor belt 33, to which the second contact unit 133 is detachably attached. The second mounting unit 132 positions the second contact unit 133 in a position that can contact the adhesive layer Ad. The recording device 1 includes a first mounting unit 141 located upstream of the cleaning unit 121 in the rotational direction of the conveyor belt 33, to which the second contact unit 133 is detachably attached. The recording device 1 includes a storage tank 112 capable of supplying a first cleaning solution into which the second contact portion 133, which is attached to the first mounting portion 141, is immersed.

[0199] According to this, the second contact portion 133 can be cleaned by immersing it in the first cleaning solution, thus suppressing a decrease in properties such as the liquid absorption capacity of the second contact portion 133.

[0200] The recording device 1 further includes a second cleaning fluid tank 123 capable of storing the second cleaning fluid into which the cleaning unit 121 is immersed. With this configuration, the second contact portion 133 is not immersed in the second cleaning fluid into which the cleaning unit 121 is immersed, so the second cleaning fluid is less likely to be contaminated. Therefore, the reduction in the cleaning ability of the adhesive layer Ad by the cleaning unit 121 can be suppressed.

[0201] The first cleaning solution has the property of swelling the adhesive layer Ad. The second contact portion 133, which is attached to the first mounting portion 141, applies the first cleaning solution to the adhesive layer Ad by contacting it. The cleaning portion 121 cleans the adhesive layer Ad to which the first cleaning solution has been applied.

[0202] According to this, by attaching it to the first mounting portion 141, the second contact portion 133 can function as a coating member that applies the first cleaning liquid to the adhesive layer Ad, while suppressing a decrease in the liquid absorption and other properties of the second contact portion 133.

[0203] The first mounting portion 141 and the second mounting portion 132 are detachably fitted with a liquid-absorbing first contact portion 111. This allows the second contact portion 133 and the first contact portion 111 to be swapped as needed, enabling continued use.

[0204] The first mounting portion 141 allows the second contact portion 133 to be displaced between a contact position that contacts the adhesive layer Ad and a non-contact position that does not contact the adhesive layer Ad. This allows the second contact portion 133 or the first contact portion 111 attached to the first mounting portion 141 to be cleaned by immersion in a cleaning solution without functioning as a coating member.

[0205] The recording device 1 further includes a pressing member 142 capable of pressing the second contact portion 133. This allows for further suppression of the deterioration of properties such as the liquid absorption capacity of the second contact portion 133 due to the absorption of the cleaning liquid and the pressing by the pressing member 142.

[0206] The recording device 1 according to the above embodiment of this disclosure is based on having the configuration described above, but it is of course possible to make partial changes or omissions to the configuration without departing from the gist of this disclosure. The above embodiment and the other embodiments described below can be implemented in combination with each other to the extent that they do not contradict the technical context. Other embodiments are described below.

[0207] In the above embodiment, the first cleaning fluid tank 113 may be omitted. In this case, as shown in Figure 3, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 may be immersed in the liquid stored in the second cleaning fluid tank 123.

[0208] In this embodiment, the second cleaning fluid tank 123 opens upward in the range from the -Y direction side of the cleaning unit 121 to the +Y direction side of the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141.

[0209] In this embodiment, the first mounting portion 141, the storage tank 112, the liquid level sensor 114, the first supply portion 115, the pressing member 142, and the circulation mechanism 118 are attached to the second cleaning liquid tank 123. In this embodiment, the first supply portion 115 supplies the first cleaning liquid from the storage tank 112 to the second cleaning liquid tank 123 via a supply pipe 115c connected to the side wall of the second cleaning liquid tank 123 in the +Y direction.

[0210] In this embodiment, the cleaning liquid stored in the second cleaning liquid tank 123 may be the second cleaning liquid, the first cleaning liquid, or a mixture of the first and second cleaning liquids. When the cleaning liquid stored in the second cleaning liquid tank 123 is the second cleaning liquid, the cleaning unit 121 and the first contact unit 111 or the second contact unit 133 attached to the first mounting unit 141 are immersed in the second cleaning liquid.

[0211] When the cleaning fluid stored in the second cleaning fluid tank 123 is the first cleaning fluid, the cleaning unit 121 and the first contact part 111 or the second contact part 133 attached to the first mounting part 141 are immersed in the first cleaning fluid.

[0212] Assume that the cleaning solution stored in the second cleaning solution tank 123 is a mixture of the first cleaning solution and the second cleaning solution. In this case, the cleaning section 121 and the first contact section 111 or the second contact section 133 attached to the first mounting section 141 are immersed in the mixture of the first cleaning solution and the second cleaning solution.

[0213] The control unit 5 controls the opening degree of the valves of the opening / closing unit 115b and 125b according to the degree of pigment film formation and foreign matter adhesion in the adhesive layer Ad. As a result, the second cleaning liquid tank 123 stores either the second cleaning liquid, the first cleaning liquid, or a mixture of the first and second cleaning liquids.

[0214] Figure 3 shows the state where the liquid level of the cleaning fluid stored in the second cleaning fluid tank 123 is at liquid level Lv. The vertical position of the liquid surface, including liquid level Lv, i.e., the amount of cleaning fluid stored in the second cleaning fluid tank 123, is detected by the liquid level sensor 114. Liquid level Lv is the liquid level when the cleaning fluid is fully stored in the second cleaning fluid tank 123, while the cleaning unit 121 and the first contact unit 111 or the second contact unit 133 are immersed in the cleaning fluid.

[0215] When either the first or second cleaning solution is supplied to the cleaning solution while it is at the liquid level Lv, the cleaning solution overflows over the specified section 127 and spills out in the -Y direction. The spilled cleaning solution is discharged to the outside of the second cleaning solution tank 123 by the discharge section 129.

[0216] In this embodiment, the circulation mechanism 118 circulates the cleaning fluid stored in the second cleaning fluid tank 123. The circulation mechanism 118 is connected to the area where the cleaning fluid is stored at the bottom of the second cleaning fluid tank 123.

[0217] In this embodiment, the switching unit 118d switches the connection destination of the other end of a pipe 118c, one end of which is connected to the second cleaning fluid tank 123, to either the second cleaning fluid tank 123 or the drainage tank. The switching unit 118d is composed of, for example, a switching valve and connecting pipes that connect the second cleaning fluid tank 123 and the drainage tank. The switching of the connection destination of the other end of the pipe 118c by the switching unit 118d is performed by the control unit 5 controlling the switching valve.

[0218] When the circulation unit 118b is driven with the other end of the piping 118c connected to the second cleaning fluid tank 123, the cleaning fluid stored in the second cleaning fluid tank 123 circulates through the second cleaning fluid tank 123, the piping 118c, and the switching unit 118d. As a result, the cleaning fluid stored in the second cleaning fluid tank 123 is reused, thus reducing the amount of cleaning fluid consumed.

[0219] When the circulation unit 118b is driven with the other end of piping 118c connected to the drain tank, the cleaning fluid stored in the second cleaning fluid tank 123 is discharged into the drain tank. This allows the amount of cleaning fluid stored in the second cleaning fluid tank 123 to be adjusted to less than full capacity.

[0220] When the second cleaning liquid tank 123 is in the contact position shown in Figure 3, the coating unit 110 can apply the cleaning liquid to the adhesive layer Ad and the cleaning mechanism 120 can clean the adhesive layer Ad. When the second cleaning liquid tank 123 is in the contact position, the first contact unit 111 or the second contact unit 133 (not shown) attached to the first mounting unit 141 is in a contact position that contacts the adhesive layer Ad. When the second cleaning liquid tank 123 is in the contact position, the cleaning unit 121, the wiping unit 131, and the second contact unit 133 or the first contact unit 111 (not shown) attached to the second mounting unit 132 are in contact with the adhesive layer Ad.

[0221] When the second cleaning fluid tank 123 is in a separated position (not shown), the application of cleaning fluid to the adhesive layer Ad by the coating unit 110 and the cleaning of the adhesive layer Ad by the cleaning mechanism 120 are not performed. When the second cleaning fluid tank 123 is in a separated position, the first contact unit 111 or the second contact unit 133 attached to the first mounting unit 141 are in a non-contact position where they do not come into contact with the adhesive layer Ad. When the second cleaning fluid tank 123 is in a separated position, the cleaning unit 121, the wiping unit 131, and the second contact unit 133 or the first contact unit 111 attached to the second mounting unit 132 move away from the adhesive layer Ad.

[0222] According to the recording device 1 of this embodiment, the following effects can be obtained.

[0223] The cleaning unit 121 is immersed in the first cleaning liquid supplied from the storage tank 112. This makes it possible to immerse the second contact unit 133 or the first contact unit 111 and the cleaning unit 121 in the same cleaning liquid tank in which the first cleaning liquid is stored, thereby simplifying the configuration of the recording device 1.

[0224] In the above embodiment, the first mounting portion 141 may be provided in the first cleaning fluid tank 113 or the second cleaning fluid tank 123 so as to be movable in the Z-axis direction. This allows, for example, when the second cleaning fluid tank 123 on which the first mounting portion 141 is provided is in a contact position, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 to be positioned in a non-contact position. The non-contact position is a position in which the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 does not come into contact with the adhesive layer Ad. Alternatively, even if the outer diameter of the first contact portion 111 and the outer diameter of the second contact portion 133 are different, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 can be positioned in a contact position that comes into contact with the adhesive layer Ad.

[0225] In the above embodiment, the width of the first contact portion 111 and the second contact portion 133 in the X-axis direction may be shorter than the width of the adhesive layer Ad. In this case, multiple first contact portions 111 and second contact portions 133 are provided. Each of the multiple first contact portions 111 and the multiple second contact portions 133 may be arranged in a so-called staggered arrangement, where, when viewed from above, multiple rows are arranged in the X-axis direction, and these rows are arranged alternately in the Y-axis direction. In this case, the width of the rows formed by each of the multiple first contact portions 111 and the multiple second contact portions 133 in the X-axis direction may be equal to or greater than the width of the adhesive layer Ad. In this case, multiple first mounting portions 141 and second mounting portions 132 are provided corresponding to the multiple first contact portions 111 and the multiple second contact portions 133.

[0226] In the above embodiment, the pressing member 142 does not have to be positioned in a location that allows it to contact the circumferential surface of the first contact portion 111 or the second contact portion 133 which is immersed in the cleaning solution. For example, the pressing member 142 may be positioned in a location that allows it to contact the circumferential surface of the first contact portion 111 or the second contact portion 133 after it has come into contact with the adhesive layer Ad but before it is immersed in the cleaning solution.

[0227] In the above embodiment, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 does not need to rotate when the drive motor is rotationally driven while in the contact position. In this case, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 may rotate by contacting the rotationally driven conveyor belt 33 when in the contact position. In this case, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 rotates when the drive motor is rotationally driven while in the non-contact position.

[0228] In the above embodiment, the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 does not need to be rotationally driven. In this case, when the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 is in the contact position, it may rotate by contacting the rotationally driven conveyor belt 33. In this case, when the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141 is in the non-contact position, it may rotate by contacting the rotationally driven pressing member 142. In this case, a drive motor (not shown) controlled by the control unit 5 is connected to the pressing member 142. In this case, there does not need to be a drive motor to rotate the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141.

[0229] In the above embodiment, the second contact portion 133 attached to the first mounting portion 141 does not need to be in contact with the adhesive layer Ad. In this case, the first cleaning liquid tank 113 or the second cleaning liquid tank 123, where the first mounting portion 141 is provided, functions as a cleaning liquid tank that cleans the second contact portion 133 with the stored cleaning liquid. Furthermore, in this case, if foreign matter such as pigment film and dust adhering to the adhesive layer Ad can be removed by cleaning the adhesive layer Ad with the cleaning mechanism 120, the coating portion 110 does not need to have the function of applying cleaning liquid to the adhesive layer Ad. In this case, the recording device 1 does not need to have the first contact portion 111.

[0230] In the above embodiment, the pressing member 142 does not need to constantly press the first contact portion 111 or the second contact portion 133 attached to the first mounting portion 141.
