DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of a recording device will be described below. In the following description, the direction intersecting the vertical direction Z is referred to as the width direction X, and the direction intersecting both the vertical direction Z and the width direction X is referred to as the front-rear direction Y. One of the width directions X is referred to as the first width direction X1, and the other of the width directions X is referred to as the second width direction X2. One of the front-rear directions Y is referred to as the front direction Y1, and the other of the front-rear directions Y is referred to as the rear direction Y2. The upper side of the vertical direction Z is referred to as the upward direction Z1, and the lower side of the vertical direction Z is referred to as the downward direction Z2. The width direction X corresponds to the width direction of the medium. Furthermore, the forward direction Y1 of the front-rear direction Y corresponds to the transport direction in which the medium is transported. In this embodiment, the width direction X, the front-rear direction Y, and the vertical direction Z are perpendicular to one another.

[0010] <Recording device 10> 1 to 3, the recording device 10 is configured to record on a medium M. The recording device 10 may be configured to record an image on the medium M by ejecting a liquid onto the medium M.

[0011] The recording device 10 may include a housing 11. The recording device 10 includes a transport unit 20 and a recording unit 30. The recording device 10 may also include a cleaning mechanism 40, a detection unit 60, an adjustment unit 70 (see FIG. 3), and a control unit 100.

[0012] The housing 11 may be configured to house the conveying unit 20 and the recording unit 30. In particular, the housing 11 may be configured to house a part or all of the conveying belt 21 described below. The housing 11 may be provided with an opening / closing cover (not shown).

[0013] The transport unit 20 can transport the medium M in the forward direction Y1, but may also be able to transport the medium M in the backward direction Y2. In particular, the transport unit 20 is configured to transport the medium M while supporting the medium M. Note that the medium M is long in the forward-backward direction Y, but may also be long in the width direction X.

[0014] The conveying unit 20 includes a conveying belt 21 for conveying the medium M in the forward direction Y1. The conveying belt 21 is configured to convey the medium M while supporting the medium M. The conveying belt 21 is provided in an endless shape. The conveying belt 21 includes an outer peripheral surface 21a and an inner peripheral surface 21b. The conveying belt 21 can support the medium M on a support surface 21c, which is the upper surface of the outer peripheral surface 21a. In this way, the conveying belt 21 supports the medium M to be conveyed.

[0015] An adhesive layer 23 is provided on the outer peripheral surface 21a of the conveyor belt 21. The adhesive layer 23 is formed over the entire periphery of the outer peripheral surface 21a by applying an adhesive to the outer peripheral surface 21a of the conveyor belt 21. The adhesive layer 23 has adhesiveness. The adhesive may be a thermoplastic resin. The adhesive layer 23 is a layer for adhering the medium M. Therefore, the conveyor belt 21 can transport the medium M in a state where the medium M is adhered to the outer peripheral surface 21a by the adhesive layer 23.

[0016] The conveying unit 20 includes a plurality of rollers. For example, the conveying unit 20 may include a first roller 24 and a second roller 25 as the plurality of rollers. In this case, the conveying belt 21 is wound around the first roller 24 and the second roller 25. Therefore, the inner circumferential surface 21b of the conveying belt 21 contacts the first roller 24 and the second roller 25.

[0017] The first roller 24 and the second roller 25 are configured to be rotatable. The conveying unit 20 includes a first driving unit 26. The first driving unit 26 is a driving source for rotating the first roller 24. The first driving unit 26 may be, for example, a motor. The first driving unit 26 rotates the first roller 24 to rotate the conveyor belt 21. That is, the first driving unit 26 transmits a driving force to the first roller 24 to drive the conveyor belt 21. The conveyor belt 21 can rotate by the rotation of the first roller 24 in a rotation direction R1. The rotation direction R1 is the direction in which the support surface 21c of the conveyor belt 21 moves in the forward direction Y1. The second roller 25 rotates in accordance with the rotation of the conveyor belt 21. That is, the second roller 25 rotates in accordance with the rotation of the first roller 24.

[0018] The recording unit 30 performs recording on the medium M supported by the conveyor belt 21. The recording unit 30 may be configured to record on the medium M by ejecting a liquid. The recording unit 30 may employ a so-called inkjet method.

[0019] The recording unit 30 includes a head 31. The head 31 is capable of ejecting liquid onto the medium M supported by the conveyor belt 21. The head 31 includes a plurality of nozzles 32 and a nozzle surface 32a. Each of the plurality of nozzles 32 is capable of ejecting liquid. The nozzle surface 32a is a surface on which each of the plurality of nozzles 32 opens.

[0020] The recording device 10 of this embodiment is configured as a serial type. The recording device 10 includes a carriage 33, a guide shaft 34, and a second drive unit 35 (see FIG. 3). The carriage 33 is configured to support the recording unit 30. That is, the recording unit 30 is provided on the carriage 33. The guide shaft 34 is configured to extend along the width direction X. The guide shaft 34 supports the carriage 33 so that it can move along the width direction X. That is, the carriage 33 can move along the guide shaft 34. The second drive unit 35 is a drive source for moving the carriage 33 along the guide shaft 34. The second drive unit 35 may be, for example, a motor.

[0021] The carriage 33 waits at a home position HP, which is one end position of its movement path. For example, the home position HP is one end position on the second width direction X2 side. The carriage 33 can move from the home position HP in the width direction X along the guide shaft 34 by the driving force from the second drive unit 35.

[0022] The cleaning mechanism 40 is capable of cleaning the conveyor belt 21. The cleaning mechanism 40 may be disposed so as to clean the outer peripheral surface 21a of the conveyor belt 21 from below. For example, the cleaning mechanism 40 may be disposed at a position where the conveyor belt 21 wound around the first roller 24 and the second roller 25 is sandwiched between the cleaning mechanism 40 and the recording unit 30.

[0023] The cleaning mechanism 40 includes a cleaning member 41, a blade 42, a sponge 43, a cleaning tank 44, and a third drive unit 45 (see FIG. 3).

[0024] As shown in FIG. 4, the cleaning member 41 is mounted in a cleaning tank 44 that stores cleaning liquid. The cleaning member 41 includes a cleaning brush 41a for cleaning the conveyor belt 21 and a shaft member 41b. The cleaning brush 41a is a cylindrical brush attached to the shaft member 41b extending in the width direction X. The length of the cleaning brush 41a in the width direction X exceeds the width of the conveyor belt 21, and the cleaning brush 41a is configured to rotate while contacting the entire width of the conveyor belt 21. The cleaning brush 41a is an example of a cleaning unit. The cleaning member 41 is rotated by driving a third driving unit 45 controlled by the control unit 100. That is, the third driving unit 45 rotates the cleaning member 41. As shown in FIG. 2, the cleaning member 41 is rotatable in a rotation direction R1, similar to the first roller 24. The cleaning member 41 is an example of a second rotating member. The third driving unit 45 is an example of a driving unit.

[0025] The blade 42 can wipe away cleaning liquid or the like adhering to the outer peripheral surface 21a of the rotating conveyor belt 21 by bringing its tip into contact with the outer peripheral surface 21a.

[0026] The sponge 43 comes into contact with the outer peripheral surface 21a of the rotating conveyor belt 21, and is thereby able to absorb the cleaning liquid and the like that remains on the outer peripheral surface 21a without being wiped off by the blade .

[0027] The cleaning tank 44 is a storage tank for storing a liquid cleaning liquid. As the cleaning liquid, for example, a water-soluble solvent such as water or an alcohol aqueous solution is used, and a surfactant or antifoaming agent is added as needed. The cleaning liquid is not shown in the figure.

[0028] The cleaning tank 44 rotatably supports the shaft member 41b of the cleaning member 41. The cleaning tank 44 is an example of a mounting portion. In place of the cleaning member 41, a roughening member 80 (see FIG. 5) for roughening the conveyor belt 21 can be mounted in the cleaning tank 44. The roughening member 80 will be described later.

[0029] The detection unit 60 is capable of detecting the state of the outer peripheral surface 21a of the conveyor belt 21. The detection unit 60 may be provided at a position facing the outer peripheral surface 21a of the conveyor belt 21. For example, the detection unit 60 is provided on the carriage 33. The detection unit 60 may be an imaging unit such as a digital camera. The detection unit 60 captures an image of the outer peripheral surface 21a of the conveyor belt 21.

[0030] The adjustment unit 70 can adjust the position of the cleaning tank 44 in the vertical direction Z. The adjustment unit 70 includes, for example, an adjustment mechanism (not shown) and an adjustment drive unit 71 that drives the adjustment mechanism. The adjustment unit 70 moves the cleaning tank 44 up and down in the vertical direction Z by driving the adjustment drive unit 71. This allows the adjustment unit 70 to adjust the relative position in the vertical direction Z between the outer circumferential surface 21a of the conveyor belt 21 and the cleaning member 41. In other words, the adjustment unit 70 can adjust the distance between the outer circumferential surface 21a of the conveyor belt 21 and the cleaning member 41. The adjustment drive unit 71 may be, for example, a motor.

[0031] <Control unit 100> Next, the control unit 100 will be described with reference to FIG. The control unit 100 controls the recording device 10. The control unit 100 controls various operations executed by the recording device 10. The control unit 100 can be configured as a circuit including one or more processors that execute various processes according to a computer program, one or more dedicated hardware circuits that execute at least some of the various processes, or a combination thereof. The hardware circuit is, for example, an application-specific integrated circuit. The processor includes a CPU and memory such as RAM and ROM, and the memory stores program code or instructions configured to cause the CPU to execute processes. The memory, i.e., computer-readable medium, includes any readable medium that can be accessed by a general-purpose or dedicated computer.

[0032] In particular, the control unit 100 is connected to the first driving unit 26, the recording unit 30, the second driving unit 35, the third driving unit 45, the detection unit 60, and the adjustment unit 70. The control unit 100 controls the first driving unit 26, the recording unit 30, the second driving unit 35, the third driving unit 45, the detection unit 60, and the adjustment unit 70 by outputting control signals. The control unit 100 can input the detection results by the detection unit 60. The location where the control unit 100 is arranged is not particularly limited.

[0033] <Roughening material 80> Next, an example of a roughening member 80 that can be attached to the cleaning tank 44 will be described with reference to Figures 5 and 6. Note that the directions shown in the description of the roughening member 80 refer to the directions when the roughening member 80 is attached to the cleaning tank 44. The roughening member 80 is an example of a first rotating member.

[0034] The roughening member 80 is configured to be attachable to the cleaning tank 44. The roughening member 80 is replaceable with the cleaning member 41. That is, the roughening member 80 can be attached to the cleaning tank 44 in place of the cleaning member 41, and the cleaning member 41 can be attached to the cleaning tank 44 in place of the roughening member 80. In other words, the cleaning tank 44 can selectively attach either the cleaning member 41 or the roughening member 80. The roughening member 80 has a shaft member 87 and a cutting portion 83. The shaft member 87 is an axis extending in the width direction X. The shaft member 87 is a member for attaching the roughening member 80 to the cleaning tank 44. When the roughening member 80 is attached to the cleaning tank 44, the shaft member 87 is connected to the third drive unit 45. That is, the roughening member 80 is rotated by the drive of the third drive unit 45. In other words, the third driving unit 45 rotates the roughening member 80 attached to the cleaning tank 44.

[0035] A wavy groove 87a is provided along the circumferential direction at one end of the shaft member 87 in the width direction X. An engaging member 88 fixed to the cleaning tank 44 engages with the groove 87a. When the shaft member 87 rotates with the engaging member 88 engaged with the groove 87a, the roughening member 80 swings in the width direction X along the groove 87a. In other words, the roughening member 80 is movable in the width direction X.

[0036] The cutting unit 83 is attached to a shaft member 87. The cutting unit 83 is capable of cutting the outer peripheral surface 21a of the conveyor belt 21 before the adhesive layer 23 is formed. The cutting unit 83 is attached to the shaft member 87 so as to cover the shaft member 87. The cutting unit 83 is, for example, a metal brush. The cutting unit 83 may also be a metal file, a paper file, or a nylon file. The material of the cutting unit 83 is not particularly limited. The roughening member 80 is attached to the cleaning tank 44 so that the cutting unit 83 is immersed in the cleaning liquid.

[0037] With the roughening member 80 attached to the cleaning tank 44, the adjustment unit 70 adjusts the distance between the outer peripheral surface 21a of the conveyor belt 21 and the roughening member 80. When the cleaning tank 44 is moved in the upward direction Z1 by the driving of the adjustment drive unit 71 of the adjustment unit 70, the cutting unit 83 comes into contact with the outer peripheral surface 21a of the conveyor belt 21. When the first drive unit 26 and the third drive unit 45 are driven while the cutting unit 83 is in contact with the outer peripheral surface 21a of the conveyor belt 21, the cutting unit 83 slides against the outer peripheral surface 21a.

[0038] <Roughening treatment> Here, the roughening process will be described. The roughening process is a process that is performed, for example, when the conveyor belt 21 is replaced. The control unit 100 performs the roughening process before an operator applies adhesive to the outer peripheral surface 21a of the replaced conveyor belt 21. The roughening process is performed in a state in which the roughening member 80 is attached to the cleaning tank 44. The roughening member 80 may be configured so that it can be manually attached to the cleaning tank 44 by an operator. The roughening process is a process in which the cutting portion 83 of the roughening member 80 cuts the outer peripheral surface 21a of the conveyor belt 21, thereby increasing the surface area of the outer peripheral surface 21a.

[0039] In the roughening process, the control unit 100 controls the adjustment unit 70 to relatively change the position of the outer peripheral surface 21a of the conveyor belt 21 and the position of the cutting unit 83 of the roughening member 80 attached to the cleaning tank 44. Then, the control unit 100 drives the first drive unit 26 and the third drive unit 45 with the cutting unit 83 in contact with the outer peripheral surface 21a of the conveyor belt 21. As a result, the cutting unit 83 slides against the outer peripheral surface 21a of the conveyor belt 21, thereby cutting the outer peripheral surface 21a of the conveyor belt 21. In addition, in the roughening process, the blade 42 and the sponge 43 slide in contact with the outer peripheral surface 21a of the conveyor belt 21, thereby cleaning the outer peripheral surface 21a of the conveyor belt 21.

[0040] An example of the roughening process will be described in detail below with reference to the flowchart in Fig. 7. It is assumed that a roughening member 80 is attached to the cleaning tank 44. In addition, in the initial state, the cleaning tank 44 is positioned on the downward direction Z2 side within the range of movement of the adjustment unit 70, and the cutting portion 83 of the roughening member 80 is spaced apart from the outer peripheral surface 21a of the conveyor belt 21.

[0041] 7, in step S1, the control unit 100 performs roughening control. The roughening control includes a process of driving the first driving unit 26 and the third driving unit 45. The roughening control is a control for cutting the outer peripheral surface 21a of the conveyor belt 21.

[0042] First, the control unit 100 drives the adjustment drive unit 71 of the adjustment unit 70 to adjust the relative position in the vertical direction Z between the outer circumferential surface 21a of the conveyor belt 21 and the roughening member 80. Specifically, the control unit 100 moves the cleaning tank 44 in the upward direction Z1 to a position where the cutting unit 83, the blade 42, and the sponge 43 contact the outer circumferential surface 21a of the conveyor belt 21.

[0043] Next, the control unit 100 drives the first drive unit 26 to rotate the conveyor belt 21 with the cutting unit 83, the blade 42, and the sponge 43 in contact with the outer peripheral surface 21a of the conveyor belt 21. The control unit 100 also drives the third drive unit 45 to rotate the roughening member 80. That is, the control unit 100 drives the first drive unit 26 while driving the third drive unit 45. The control unit 100 also drives the first drive unit 26 to rotate the first roller 24 in the rotation direction R1. As a result, the support surface 21c of the conveyor belt 21 is moved forward in the Y1 direction. The control unit 100 also drives the third drive unit 45 to rotate the roughening member 80 in the rotation direction R1. Here, the engagement member 88 engages with the groove 87a formed in the shaft member 87 of the roughening member 80, causing the roughening member 80 to oscillate in the width direction X as the roughening member 80 rotates in the rotation direction R1. As a result, the direction in which the outer peripheral surface 21a of the conveyor belt 21 is cut becomes a wave-like undulating direction as shown in FIG. 6. For example, the control unit 100 may drive the first drive unit 26 so that the conveyor belt 21 rotates a predetermined number of times. When the roughening control is completed, the control unit 100 drives the adjustment drive unit 71 of the adjustment unit 70 to move the cleaning tank 44 downward in the Z2 direction.

[0044] In step S2, the control unit 100 causes the detection unit 60 to detect the state of the outer peripheral surface 21a of the conveyor belt 21. For example, the control unit 100 causes the detection unit 60 to capture an image of the outer peripheral surface 21a of the conveyor belt 21. At this time, the control unit 100 may drive the first drive unit 26 and the second drive unit 35 to capture an image of the entire state of the outer peripheral surface 21a of the conveyor belt 21. When the detection unit 60 detects the state of the outer peripheral surface 21a of the conveyor belt 21, the control unit 100 proceeds to processing in step S3.

[0045] In the process of step S3, the control unit 100 determines whether the roughening of the outer peripheral surface 21a of the conveyor belt 21 has been completed. For example, the control unit 100 determines whether there are any areas on the outer peripheral surface 21a where cutting is insufficient based on the detection result of detecting the state of the outer peripheral surface 21a of the conveyor belt 21 in step S2. For example, the control unit 100 stores an image of the outer peripheral surface 21a of the conveyor belt 21 in a state where cutting is sufficient as sample data. Then, the control unit 100 compares the sample data with the image of the outer peripheral surface 21a of the conveyor belt 21 taken by the detection unit 60 in step S2. In this way, the control unit 100 determines whether there are any areas on the outer peripheral surface 21a where cutting is insufficient.

[0046] When there is no portion of the outer peripheral surface 21a where cutting is insufficient, the control unit 100 determines that roughening of the outer peripheral surface 21a of the conveyor belt 21 is complete. When the control unit 100 determines that roughening of the outer peripheral surface 21a of the conveyor belt 21 is complete (step S3: YES), the control unit 100 ends the roughening process.

[0047] If there are any areas where cutting of the outer peripheral surface 21a is insufficient, the control unit 100 determines that roughening of the outer peripheral surface 21a of the conveyor belt 21 is not complete. If the control unit 100 determines that roughening of the outer peripheral surface 21a of the conveyor belt 21 is not complete (step S3: NO), the control unit 100 proceeds to the processing of step S4.

[0048] In the processing of step S4, the control unit 100 identifies a target range for re-roughening control. Re-roughening control is control for re-cutting areas of the outer peripheral surface 21a where cutting is insufficient. For example, the control unit 100 identifies areas of the outer peripheral surface 21a where cutting is insufficient as a target range for re-roughening control based on the detection results of detecting the state of the outer peripheral surface 21a of the conveyor belt 21 in step S2. After the control unit 100 identifies the target range for re-roughening control, it proceeds to processing of step S5.

[0049] In the process of step S5, the control unit 100 performs re-roughening control for the target area identified in step S4. For example, the control unit 100 drives the first drive unit 26 to rotate the conveyor belt 21 so that the target area identified in step S4 moves to a position facing the roughening member 80. Then, the control unit 100 controls the conveyor belt 21 to cut the outer peripheral surface 21a of the conveyor belt 21 in the identified target area. Note that the control for cutting the outer peripheral surface 21a of the conveyor belt 21 is substantially the same as the roughening control in step S1, and therefore a description thereof will be omitted. In the process of step S5, the control unit 100 may adjust the relative position of the outer peripheral surface 21a of the conveyor belt 21 and the roughening member 80 in the vertical direction Z in accordance with the detection result of the detection unit 60. For example, the control unit 100 may adjust the pressing force when the cutting unit 83, the blade 42, and the sponge 43 contact the outer peripheral surface 21a of the conveyor belt 21 in accordance with the detection result of the detection unit 60.

[0050] When the control unit 100 finishes the re-roughening control, the control unit 100 proceeds to the process of step S2. Thereafter, the control unit 100 repeats the processes of steps S2 to S5 until it determines in the process of step S3 that the roughening has been completed.

[0051] When the roughening process is completed, the worker removes the roughening member 80 from the cleaning tank 44 and attaches the cleaning member 41 to the cleaning tank 44. When the roughening process is completed, the worker applies an adhesive to the outer peripheral surface 21a of the conveyor belt 21 to form an adhesive layer 23 on the outer peripheral surface 21a of the conveyor belt 21. In this way, the worker performs the roughening process on the outer peripheral surface 21a of the conveyor belt 21 when replacing the conveyor belt 21.

[0052] As described above, the recording device 10 of this embodiment can provide the following effects.

[0053] According to this embodiment, the roughening work of the outer peripheral surface 21a of the conveyor belt 21 can be performed by driving the third drive unit 45 with the roughening member 80 attached to the cleaning tank 44. Therefore, the work efficiency of the roughening work can be improved compared to when the roughening work is performed manually.

[0054] According to this embodiment, the roughening member 80 can be attached to the cleaning tank 44 that stores the cleaning liquid, instead of the cleaning member 41. This simplifies the configuration of the recording device 10 compared to when the cleaning member 41 and the roughening member 80 are provided in separate locations. Furthermore, because the cutting portion 83 attached to the roughening member 80 is immersed in the cleaning liquid, it is possible to remove shavings that are produced by cutting the outer peripheral surface 21a of the conveyor belt 21.

[0055] According to this embodiment, since the roughening member 80 can swing in the width direction X, the surface area of the outer circumferential surface 21a of the conveyor belt 21 can be increased compared to when roughening is performed only in one direction along the front-rear direction Y. This increases the adhesive strength of the adhesive layer 23 to the conveyor belt 21.

[0056] According to this embodiment, since the adjustment unit 70 that adjusts the distance between the outer peripheral surface 21a of the conveyor belt 21 and the roughening member 80 is provided, it is possible to adjust the pressing force of the cutting unit 83 against the outer peripheral surface 21a of the conveyor belt 21. Therefore, it is possible to adjust the degree of roughening of the outer peripheral surface 21a of the conveyor belt 21.

[0057] [Example of change] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0058] The control unit 100 may terminate the roughening process when the roughening control in step S1 is completed, thereby reducing the time required for the roughening process.

[0059] The recording device 10 may be configured to be able to display predetermined information based on the detection result of the condition of the outer peripheral surface 21a of the conveyor belt 21 by the detection unit 60. For example, the predetermined information may be the image itself captured by the detection unit 60, or the result of determination by the control unit 100 of the condition of the outer peripheral surface 21a of the conveyor belt 21 based on the detection result by the detection unit 60. This makes it easier for the worker to check the condition of the outer peripheral surface 21a of the conveyor belt 21.

[0060] The determination in step S3 of the roughening process may be made by an operator operating a predetermined operation unit. That is, in the roughening process, the operator may determine whether the roughening is complete by checking the state of the outer circumferential surface 21a of the conveyor belt 21. This prevents the roughening process from ending without properly completing the roughening work due to a malfunction of the control unit 100 or the like.

[0061] The re-roughening control may be executed as a process separate from the roughening process. For example, the control unit 100 may be configured to execute the re-roughening control in response to the receipt of an operation of a predetermined operation unit. In this case, the target range of the re-roughening control may be determined by the operation of the operation unit by the operator. This allows the operator to decide whether or not to execute the re-roughening control as needed.

[0062] The distance by which the cleaning tank 44 is moved upward Z1 during the roughening process may be determined by operating a predetermined operating unit. This allows the operator to adjust the pressing force when the cutting unit 83, the blade 42, and the sponge 43 contact the outer circumferential surface 21a of the conveyor belt 21 during the roughening process.

[0063] The control content of the roughening process may be changed as appropriate. For example, the control unit 100 may only control the driving of the first driving unit 26 without driving the third driving unit 45.

[0064] The mechanism for swinging the roughening member 80 along the width direction X may be changed as appropriate. For example, the recording device 10 may include an adjustment unit that can adjust the relative position in the width direction X between the outer circumferential surface 21a of the conveyor belt 21 and the roughening member 80, and the relative position may be adjusted by driving the adjustment unit. Furthermore, the recording device 10 does not necessarily have to include a mechanism for swinging the roughening member 80 along the width direction X.

[0065] The specific configuration of the adjustment unit 70 may be changed as appropriate as long as it can adjust the relative position in the vertical direction Z between the outer circumferential surface 21a of the conveyor belt 21 and the cleaning tank 44. For example, the adjustment unit 70 may be an adjustment mechanism that can manually adjust the height of the roughening member 80 in the vertical direction Z when the roughening member 80 is attached.

[0066] The cleaning member 41 and the roughening member 80 may share a common shaft member. In other words, when replacing the cleaning member 41 and the roughening member 80, the cleaning brush 41a and the cutting portion 83 may be replaced with the same shaft member. In this case, the cutting portion 83 corresponds to the first rotating member, and the cleaning brush 41a corresponds to the second rotating member.

[0067] The detection unit 60 may be an optical sensor that irradiates the outer peripheral surface 21a of the conveyor belt 21 with light and measures the amount of reflected light. In this case, the control unit 100 stores, as sample data, the amount of reflected light measured when light is irradiated onto the outer peripheral surface 21a of the conveyor belt 21 in a sufficiently cut state. Then, in step S3 of the roughening process, the control unit 100 compares the sample data with the amount of reflected light measured by the detection unit 60 in step S2 when light is irradiated onto the outer peripheral surface 21a of the conveyor belt 21. In this way, the control unit 100 determines whether or not there are any areas on the outer peripheral surface 21a where cutting is insufficient.

[0068] The recording device 10 may be provided with an adjustment unit capable of adjusting the position of the conveyor belt 21 in the vertical direction Z, instead of or in addition to the adjustment unit 70 capable of adjusting the position of the cleaning tank 44 in the vertical direction Z. In this case, the control unit 100 may control the conveyor belt 21 to move downward in the Z2 direction during the roughening process so that the outer circumferential surface 21a of the conveyor belt 21 comes into contact with the cutting unit 83.

[0069] The recording device 10 may be configured so that the roughening member 80 can be attached to the cleaning tank 44 under the control of the control unit 100.

[0070] The recording device 10 may be configured so that the roughening member 80 can be stored inside the housing 11. In this case, it is preferable that a space capable of storing the roughening member 80 is formed inside the housing 11 of the recording device 10.

[0071] The location of the roughening member 80 may be changed as appropriate. For example, the roughening member 80 may be provided at a location separate from the cleaning mechanism 40. In this case, the control unit 100 may include a drive unit different from the third drive unit 45 that drives the cleaning member 41, and may rotate the roughening member 80 by driving this drive unit. In this manner, the recording apparatus 10 may be provided with both the cleaning mechanism 40 and the roughening member 80 in an operable manner. This eliminates the need to attach the roughening member 80 to the recording apparatus 10 when roughening the outer peripheral surface 21a of the conveyor belt 21. Furthermore, both the cleaning member 41 and the roughening member 80 may be provided in the cleaning tank 44. Furthermore, the recording apparatus 10 does not need to include the cleaning mechanism 40 as long as it includes the roughening member 80.

[0072] The recording device 10 may be configured as a line type that simultaneously records across the width of the medium M using a head 31 extending in the width direction X.

[0073] The recording device 10 may be a laser printer that records an image by depositing toner using laser light. The recording method of the recording device 10 may also be a recording method other than the inkjet method or the laser method.

[0074] [Note] The technical concepts and their effects that can be understood from the above-described embodiments and modifications will be described below. The technical concepts and their effects can be combined with each other to the extent that they are not technically inconsistent.

[0075] (A) The recording device includes a recording unit that records on a medium, a conveying belt that is wound around multiple rollers and is capable of conveying the medium while being attached to the outer peripheral surface by an adhesive layer formed on the outer peripheral surface, a mounting unit that is capable of mounting a first rotating member having a cutting portion for cutting the outer peripheral surface before the adhesive layer is formed, and a drive unit that rotates the first rotating member mounted on the mounting unit.

[0076] In such a recording device, the outer peripheral surface of the conveyor belt can be roughened by driving the drive unit with the first rotating member attached to the attachment unit, which improves the work efficiency of the roughening work compared to manual roughening work.

[0077] (B) The recording device includes a recording unit that records on a medium, a conveying belt that is wound around multiple rollers and is capable of conveying the medium while being attached to the outer circumferential surface by an adhesive layer formed on the outer circumferential surface, a first rotating member that has a cutting unit for cutting the outer circumferential surface before the adhesive layer is formed, and a driving unit that rotates the first rotating member.

[0078] In such a recording device, by driving the drive unit, the first rotating member provided in the recording device can perform the roughening work on the outer surface of the conveyor belt, which improves the work efficiency of the roughening work compared to when the roughening work is done manually.

[0079] (C) In the above recording device, the mounting section is a storage tank for storing liquid, and a second rotating member having a cleaning section for cleaning the conveying belt can be mounted in place of the first rotating member, and the first rotating member may be mounted on the mounting section so that the cutting section is immersed in the liquid.

[0080] According to the above configuration, the first rotating member and the second rotating member can be attached to a reservoir tank that stores liquid. This simplifies the configuration of the recording device compared to when the first rotating member and the second rotating member are provided in separate locations. Furthermore, because the cutting part attached to the first rotating member is immersed in the liquid, shavings produced by cutting the outer surface of the conveyor belt can be removed.

[0081] (D) In the above recording device, the first rotating member may be movable in a width direction that intersects with a transport direction in which the medium is transported by the transport belt.

[0082] According to the above configuration, since the first rotating member is movable in the width direction, the surface area of the outer circumferential surface of the conveyor belt can be increased compared to when roughening is performed only in one direction along the conveyance direction, thereby increasing the adhesive strength of the adhesive layer to the conveyor belt.

[0083] (E) The above-mentioned recording device may include an adjustment unit that adjusts the distance between the outer circumferential surface and the first rotating member.

[0084] According to the above configuration, since an adjustment unit that adjusts the distance between the outer circumferential surface of the conveyor belt and the first rotating member is provided, it is possible to adjust the pressing force of the cutting unit against the outer circumferential surface of the conveyor belt, and therefore it is possible to adjust the degree of roughening of the outer circumferential surface of the conveyor belt.
