[0013] Hereinafter, one embodiment of the recording apparatus equipped with a transport device will be described with reference to the accompanying drawings. The recording apparatus is, for example, an inkjet printer that records text, photographs, and other images by ejecting ink, an example recording material, onto a medium such as paper or cloth. The recording apparatus is not limited to inkjet printing; it can be a toner-jet printer or use other recording methods.

[0014] like Figure 1 As shown, the recording device 11 includes a recording unit 12, a control unit 13, a receiving unit 14, and a conveying device 15.

[0015] The recording unit 12 is configured to perform recording on the medium 99. The recording unit 12 is, for example, a head. Therefore, the recording unit 12 in this example has one or more nozzles 16. In this example, the recording unit 12 is a serial head that scans the medium 99. The recording unit 12 may also be a line head that records across the width of the medium 99. The recording unit 12 records an image on the medium 99 by spraying liquid onto the medium 99.

[0016] The control section 13 controls the recording device 11. The control section 13 controls, for example, the recording section 12, the conveyance device 15, and the like. The control section 13 can be configured as a circuit including: α: one or more processors that execute various processes in accordance with a computer program; β: one or more dedicated hardware circuits for specific use that execute at least a part of the processes in the various processes; or γ: a combination thereof. The processor includes a CPU, a RAM, a ROM, and the like, and the memory stores program codes or instructions configured in such a manner that the CPU executes the processes. The memory, that is, the computer-readable medium includes a so-called readable medium that can be accessed by a general-purpose or a dedicated computer.

[0017] The reception section 14 is configured to receive an instruction from a user. The reception section 14 is, for example, an operation panel. The reception section 14 is connected to the control section 13. An instruction from the user received by the reception section 14 is input to the control section 13. The reception section 14 can receive an instruction related to the operation of the pressing member 33 to press the absorbent material 52 from the user as described later. The reception section 14 can display various information related to the recording device 11.

[0018] The conveyance device 15 is a device that conveys the medium 99. In the present example, the conveyance device 15 intermittently conveys the medium 99. The conveyance device 15 can also continuously convey the medium 99.

[0019] The conveyance device 15 has a plurality of rollers, a drive source 21, a conveyance belt 22, and a cleaning mechanism 23. The conveyance device 15 can also have a control section that controls the conveyance device 15 in addition to the control section 13 provided in the recording device 11. In this case, for example, the control section 13 provided in the recording device 11 and the control section provided in the conveyance device 15 communicate. The conveyance device 15 can have the control section instead of the control section 13. In this case, for example, the control section provided in the conveyance device 15 controls the recording section 12. In the case where the conveyance device 15 has the control section, the reception section 14 can be connected to the control section. For example, the conveyance device 15 can have the reception section 14.

[0020] The conveyance device 15 of the present example has, as a plurality of rollers, for example, a first roller 24 and a second roller 25. The first roller 24 and the second roller 25 convey the medium 99 in a first direction Al. The first direction Al is a direction in which the medium 99 is conveyed. The first roller 24 and the second roller 25 are arranged side by side in the first direction Al in this order. Therefore, the first roller 24 is located upstream of the recording section 12 in the first direction Al. The second roller 25 is located downstream of the recording section 12 in the first direction Al.

[0021] The driving source 21 is, for example, a motor that rotates a plurality of rollers. The driving source 21 is connected to, for example, the first roller 24, the second roller 25, or both. In the present example, the driving source 21 is connected to the first roller 24. Thus, the driving source 21 rotates the first roller 24. In the present example, the second roller 25 rotates in conjunction with the rotation of the first roller 24 by the conveyance belt 22.

[0022] The conveyance belt 22 is wound around a plurality of rollers. In the present example, the conveyance belt 22 is wound around the first roller 24 and the second roller 25. When the driving source 21 rotates the first roller 24, the conveyance belt 22 moves, that is, circulates, along the first roller 24 and the second roller 25. Thus, the conveyance belt 22 conveys the medium 99. In the present example, the conveyance belt 22 conveys the medium 99 by intermittently moving. The conveyance belt 22, for example, circulates in the counterclockwise direction in FIG. 1. Figure 1

[0023] The conveyance belt 22 has a support surface 26 that supports the medium 99. The support surface 26 is an outer circumferential surface of the conveyance belt 22.

[0024] The conveyance belt 22 is, for example, a belt to which an adhesive is applied. The adhesive is applied to the support surface 26. By the adhesive, the medium 99 is adhered to the support surface 26. Thus, the posture of the medium 99 is stable. The medium 99 is not limited to being adhered to the support surface 26 by the adhesive, but may, for example, be adhered to the support surface 26 by suction force, electrostatic force, intermolecular force, or the like. An image is recorded on the medium 99 supported on the support surface 26 by the recording section 12.

[0025] The conveyance belt 22 is sometimes contaminated by conveying the medium 99. In particular, the support surface 26 is easily contaminated. For example, powder, fluff, dust in the air, recording material generated by the recording section 12, or the like generated from the medium 99 sometimes adheres to the support surface 26. Thus, the support surface 26 is contaminated. When the support surface 26 is contaminated, there is a possibility that a stain adheres to the medium 99. Further, when the support surface 26 is contaminated, there is a possibility that the adhesion of the support surface 26 to the medium 99 is impaired.

[0026] As shown in FIGS. 1 and 2, the cleaning mechanism 23 is a mechanism that cleans the conveyance belt 22. Specifically, the cleaning mechanism 23 cleans the support surface 26 by contacting the support surface 26. Thus, it is possible to reduce the possibility that a stain adheres to the medium 99 from the conveyance belt 22. Further, it is possible to reduce the possibility that the adhesion of the support surface 26 is impaired. Figure 1 Figure 2

[0027] ​​​The cleaning mechanism 23 is configured to contact the support surface 26 in an area where the medium 99 will not pass through. This area is, for example, opposite to the portion of the support surface 26 that moves in the second direction A2. The second direction A2 is the direction opposite to the first direction A1. On the other hand, the area where the medium 99 passes through is, for example, opposite to the portion of the support surface 26 that moves in the first direction A1. Therefore, the cleaning mechanism 23 is configured, for example, to contact the portion of the support surface 26 that moves in the second direction A2. Thus, in this example, the cleaning mechanism 23 and the recording unit 12 are configured, for example, to clamp the conveyor belt 22. Specifically, the cleaning mechanism 23 and the recording unit 12 are configured to clamp the conveyor belt 22 from above and below. Thus, the cleaning mechanism 23 cleans the support surface 26 after it has been used to support the medium 99, i.e., after the medium 99 has been peeled off. The cleaned support surface 26 then supports the medium 99 again by wrapping around it.

[0028] The cleaning mechanism 23 is controlled, for example, by the control unit 13. If the conveying device 15 is equipped with a control unit, the cleaning mechanism 23 can also be controlled by that control unit. A detailed description of the cleaning mechanism 23 will be given below.

[0029] The conveying device 15 may also include a moving mechanism 27. The moving mechanism 27 moves the conveyor belt 22 and the cleaning roller 32 relative to each other in such a way that the cleaning roller 32 of the cleaning mechanism 23 is separated from the support surface 26. The cleaning roller 32 will be described below. In this example, the moving mechanism 27 separates the cleaning roller 32 from the support surface 26 by moving the cleaning mechanism 23 relative to the conveyor belt 22. In this example, the moving mechanism 27 causes the cleaning mechanism 23 to rise and fall relative to the conveyor belt 22. The moving mechanism 27 can move the conveyor belt 22 relative to the cleaning mechanism 23, or it can move both the conveyor belt 22 and the cleaning mechanism 23. Furthermore, the moving mechanism 27 may also move the cleaning roller 32 separately, rather than moving the cleaning mechanism 23 as a whole.

[0030] Next, we will explain cleaning agency 23.

[0031] like Figure 2 as well as Figure 3 As shown, in this example, the cleaning mechanism 23 has a supply unit 31, a cleaning roller 32, a squeezing member 33, a drive unit 34, and a blowing unit 35.

[0032] The supply unit 31 is configured to supply cleaning fluid to the cleaning roller 32. The cleaning fluid is, for example, water. Alternatively, the cleaning fluid may be other liquids. The supply unit 31 includes, for example, a support tank 41, a storage tank 42, a supply pipe 43, a supply valve 44, a discharge pipe 45, and a discharge valve 46.

[0033] The support tank 41 accommodates the reservoir tank 42. In the present example, the cleaning roller 32, the pressing member 33, and the blowing portion 35 are mounted on the support tank 41. The support tank 41 has a discharge port 47. The discharge port 47 is, for example, located on the bottom surface of the support tank 41. The discharge port 47 is an opening for discharging the cleaning liquid that has overflowed from the reservoir tank 42 into the support tank 41.

[0034] The reservoir tank 42 stores the cleaning liquid. The reservoir tank 42 of the present example accommodates a part of the cleaning roller 32. Specifically, the reservoir tank 42 accommodates the lower end portion of the cleaning roller 32. Thus, the cleaning liquid is stored by the reservoir tank 42, so that the cleaning roller 32 is immersed in the cleaning liquid. In this way, the cleaning liquid is supplied to the cleaning roller 32. The reservoir tank 42 is, for example, located on the bottom surface of the support tank 41. By being accommodated in the support tank 41 by the reservoir tank 42, the possibility that the cleaning liquid stored in the reservoir tank 42 scatters around the supply portion 31 is reduced.

[0035] The supply pipe 43 is connected to a supply source of the cleaning liquid and the support tank 41. The supply source of the cleaning liquid is, for example, tap water. By causing the cleaning liquid to flow from the supply source through the supply pipe 43, the cleaning liquid is supplied into the reservoir tank 42. The cleaning liquid is stored in the reservoir tank 42 by falling after flowing into the support tank 41. The supply pipe 43 can also be connected to the reservoir tank 42.

[0036] The supply valve 44 is provided on the supply pipe 43. When the supply valve 44 is opened, the cleaning liquid is supplied into the reservoir tank 42 through the supply pipe 43. When the supply valve 44 is closed, the supply of the cleaning liquid to the reservoir tank 42 is stopped.

[0037] The discharge pipe 45 is connected to the reservoir tank 42. By causing the cleaning liquid to flow from the reservoir tank 42 through the discharge pipe 45, the cleaning liquid is discharged from the reservoir tank 42.

[0038] The discharge valve 46 is provided on the discharge pipe 45. When the discharge valve 46 is opened, the cleaning liquid is discharged from the reservoir tank 42 through the discharge pipe 45. When the discharge valve 46 is closed, the discharge of the cleaning liquid from the reservoir tank 42 is stopped.

[0039] The supply portion 31 is configured to be switchable between a supply state in which the cleaning liquid is supplied to the cleaning roller 32 and a non-supply state in which the cleaning liquid is not supplied to the cleaning roller 32. In the present example, the supply state refers to a state in which the cleaning roller 32 contacts the liquid stored in the reservoir tank 42. In the present example, the non-supply state refers to a state in which the cleaning roller 32 does not contact the liquid stored in the reservoir tank 42.

[0040] In the present example, the state of the supply section 31 is switched between the supply state and the non-supply state by varying the liquid level of the cleaning liquid that is stored in the storage tank 42. For example, the liquid level of the cleaning liquid that is stored in the storage tank 42 is varied by the control section 13 controlling the supply valve 44 and the discharge valve 46. For example, in a case where the control section 13 controls the supply valve 44 and the discharge valve 46 in such a manner that the opening degree of the supply valve 44 is larger than the opening degree of the discharge valve 46, the liquid level of the cleaning liquid will rise. In this case, in a case where the control section 13 controls the supply valve 44 and the discharge valve 46 in such a manner that the opening degree of the supply valve 44 is smaller than the opening degree of the discharge valve 46, the liquid level of the cleaning liquid will fall.

[0041] In the present example, in a case where the supply section 31 is in the supply state, the liquid level of the cleaning liquid that is stored in the storage tank 42 is the height at which the cleaning roller 32 is immersed in the cleaning liquid. In a case where the supply section 31 is in the non-supply state, the liquid level of the cleaning liquid that is stored in the storage tank 42 is the height at which the cleaning roller 32 is not immersed in the cleaning liquid. The state of the supply section 31 is not limited to being switched by varying the liquid level of the cleaning liquid that is stored in the storage tank 42, but can also be switched by, for example, the cleaning roller 32 and the storage tank 42 being relatively moved.

[0042] The cleaning roller 32 cleans the support surface 26 by being in contact with the support surface 26. The cleaning roller 32 is rotatably supported by the support groove 41.

[0043] The cleaning roller 32 includes a rotation shaft 51 and an absorbent material 52. The rotation shaft 51 is, for example, parallel to the shaft of the first roller 24 and the shaft of the second roller 25. The absorbent material 52 is a member that is capable of absorbing the cleaning liquid. The absorbent material 52 is, for example, a sponge. The absorbent material 52 is supported by the rotation shaft 51. The absorbent material 52 rotates together with the rotation shaft 51. The support surface 26 is cleaned by the absorbent material 52 being in contact with the support surface 26.

[0044] In the present example, a part of the absorbent material 52 is housed in the storage tank 42. Specifically, a lower end portion of the absorbent material 52 is housed in the storage tank 42. Therefore, in a case where the supply section 31 is in the supply state, the absorbent material 52 will come into contact with the cleaning liquid that is stored in the storage tank 42. As a result of this, the absorbent material 52 becomes a state in which the cleaning liquid is contained. In a case where the supply section 31 is in the non-supply state, the absorbent material 52 will not come into contact with the cleaning liquid that is stored in the storage tank 42.

[0045] The cleaning roller 32 is switched between a contact state in which the cleaning roller 32 is in contact with the support surface 26 and a non-contact state in which the cleaning roller 32 is separated from the support surface 26 by the moving mechanism 27. In the case where the cleaning roller 32 is in the contact state, the absorbent material 52 is in contact with the support surface 26. In the present example, the upper end portion of the absorbent material 52 is in contact with the support surface 26. In the case where the cleaning roller 32 is in the non-contact state, the absorbent material 52 is not in contact with the support surface 26.

[0046] In the case where the supply portion 31 is in the supply state and the cleaning roller 32 is in the contact state, the cleaning roller 32 cleans the support surface 26 by being rotated. In the present example, the cleaning roller 32 is rotated by the driving portion 34. The cleaning roller 32 can be driven to rotate by a driving force of the driving portion 34 or can be driven to rotate from the transport belt 22 by a driving force of the driving source 21 while being in contact with the transport belt 22. The absorbent material 52 wetted with the cleaning liquid is in contact with the support surface 26 while being rotated, so that dirt on the support surface 26 is removed.

[0047] In the present example, the cleaning roller 32 is rotated in the same direction as the direction in which the transport belt 22 is wound around when the transport belt 22 is cleaned. That is, the cleaning roller 32 is rotated in the counterclockwise direction in Figure 2 and Figure 3 In the present example, the cleaning roller 32 is rotated in such a manner that, at the contact portion of the cleaning roller 32, the transport belt 22 is moved in the second direction A2 and, in relation thereto, the absorbent material 52 is moved toward the first direction Al. Thus, the contact resistance of the transport belt 22 and the cleaning roller 32 becomes large, so that dirt on the transport belt 22 is easily removed.

[0048] The cleaning roller 32 can also be rotated in the direction opposite to the direction in which the transport belt 22 is wound around by the driving portion 34 when the transport belt 22 is cleaned. That is, the cleaning roller 32 can be rotated in the clockwise direction in Figure 2 and Figure 3 Even in this case, the cleaning roller 32 can clean the transport belt 22.

[0049] The pressing member 33 is a member that presses the absorbent material 52. The pressing member 33 is in contact with the absorbent material 52 in such a manner that the absorbent material 52 is deformed. The pressing member 33 is in contact with the absorbent material 52 in such a manner that the pressing member 33 sinks into the absorbent material 52. The pressing member 33 presses the absorbent material 52 by rotating the cleaning roller 32 in a state in which the cleaning roller 32 is in contact with the absorbent material 52.

[0050] The pressing member 33 presses the absorbent material 52 from the time the absorbent material 52 is immersed in the reservoir 42 to the time the absorbent material 52 comes into contact with the support surface 26. Thus, the absorbent material 52 that has absorbed the cleaning liquid with the reservoir 42 comes into contact with the support surface 26 after being pressed by the pressing member 33. The amount of the cleaning liquid contained in the absorbent material 52 is adjusted by being pressed. That is, the cleaning roller 32 cleans the support surface 26 with the absorbent material 52 containing an appropriate amount of the cleaning liquid when the conveyer belt 22 is cleaned. Thus, the possibility that the support surface 26 is drenched with the cleaning liquid more than necessary is reduced.

[0051] In the present example, since the cleaning roller 32 rotates in the counterclockwise direction in the state where the conveyer belt 22 is cleaned, Figure 2 and Figure 3 the pressing member 33 is located at a position that is offset in the second direction A2 with respect to the cleaning roller 32. In the case where the cleaning roller 32 rotates in the clockwise direction in the state where the conveyer belt 22 is cleaned, Figure 2 and Figure 3 the pressing member 33 is located at a position that is offset in the first direction Al with respect to the cleaning roller 32. That is, the pressing member 33 is provided on at least a part of a region from a downstream of a portion of the cleaning roller 32 that comes into contact with the cleaning liquid to an upstream of a portion of the cleaning roller 32 that comes into contact with the support surface 26 in the direction of rotation of the cleaning roller 32. As a result, the absorbent material 52 that has absorbed the cleaning liquid with the reservoir 42 comes into contact with the support surface 26 after being pressed by the pressing member 33.

[0052] In the present example, the pressing member 33 is a roller. Thus, the pressing member 33 rotates together with the cleaning roller 32 when the absorbent material 52 is pressed. The pressing member 33 is not limited to a roller, but can be a clip or a squeegee. The pressing member 33 can be any structure that deforms the absorbent material 52 by coming into contact with the absorbent material 52.

[0053] The conveyer belt 22 is properly cleaned by the pressing member 33 pressing the absorbent material 52 in the state where the supply portion 31 is in the supplied state. The amount of the cleaning liquid contained in the absorbent material 52 is reduced by the pressing member 33 pressing the absorbent material 52 in the state where the supply portion 31 is in the non-supplied state. Thus, the absorbent material 52 becomes easy to dry. Thus, the possibility that the absorbent material 52 is drenched with the cleaning liquid all the time is reduced.

[0054] When the absorbent material 52 is always wet and left for a long time, there is a possibility that the absorbent material 52 deteriorates. For example, there is a possibility that the absorbent material 52 molds. Therefore, drying of the absorbent material 52 is promoted by the pressing member 33, so that the possibility of deterioration of the absorbent material 52 is reduced. For example, it is preferable that, in a case where it is predicted that the conveyance device 15 is not used for a long time, the absorbent material 52 is pressed by the pressing member 33, so that drying of the absorbent material 52 is promoted.

[0055] The driving section 34 is configured to cause the cleaning roller 32 to rotate. When the driving section 34 causes the cleaning roller 32 to rotate, the absorbent material 52 is pressed by the pressing member 33. In the present example, the driving section 34 is a motor connected to the cleaning roller 32. Therefore, in the present example, the driving section 34 causes the cleaning roller 32 to drive rotation. The driving section 34 can also be configured to cause the cleaning roller 32 to driven rotation. That is, it can also be a structure in which a driving force for causing the cleaning roller 32 to rotate is not transmitted to the cleaning roller 32 but to other elements. For example, the driving section 34 can also be a motor connected to the pressing member 33. In this case, the cleaning roller 32 is caused to driven rotation by causing the pressing member 33 to rotate by the driving section 34. In addition to this, for example, it can also be a structure in which a driving force of the driving source 21 is transmitted to the cleaning roller 32 via the conveyance belt 22. That is, the driving section 34 can be omitted, and a driving force of the driving source 21 is transmitted to the cleaning roller 32 via the conveyance belt 22. In this case, it becomes a structure in which the driving source 21 causes the cleaning roller 32 to rotate. The cleaning roller 32 is caused to driven rotation while being in contact with the support surface 26 by causing the conveyance belt 22 to circulate by the driving source 21.

[0056] The blowing section 35 is connected to the air blower 54. In the present example, the air blower 54 is a structure outside the recording device 11. In other words, the air blower 54 is connected to the recording device 11 or the conveyance device 15. The air blower 54 delivers gas to the blowing section 35.

[0057] The blowing section 35 is configured to give directivity to the wind pressure (energy) of the gas delivered from the air blower 54. The blowing section 35 is, for example, an air knife. The blowing section 35 blows the gas delivered from the air blower 54 to the conveyance belt 22. Specifically, the blowing section 35 blows the gas to the support surface 26.

[0058] The blowing section 35 blows gas toward the support surface 26 cleaned by the cleaning roller 32. That is, the blowing section 35 blows gas toward the support surface 26 after the cleaning roller 32 contacts. Specifically, gas is blown by the blowing section 35 after a certain region of the support surface 26 is cleaned by the cleaning roller 32. Thus, the blowing section 35 dries the support surface 26 wetted by the cleaning liquid. In the present example, the blowing section 35 is positioned at a position shifted in the second direction A2 with respect to the cleaning roller 32. In addition, regarding drying of the support surface 26 by the blowing section 35, it is also possible to not make the residual moisture in the support surface 26 zero.

[0059] The blowing section 35 is configured to blow gas toward the cleaning roller 32. The blowing section 35 is configured to not be limited to blowing gas toward the support surface 26, but can also blow gas toward the absorbent material 52. In the present example, the blowing section 35 is configured to be able to switch the object of the blown gas to the support surface 26 or the cleaning roller 32.

[0060] In the present example, the blowing section 35 has an inner drum 55 and an outer drum 56. The inner drum 55 and the outer drum 56 each have a blowout port that blows out gas. The gas blown out by the blower 54 passes through in the order of the inner drum 55, the outer drum 56.

[0061] The inner drum 55 is housed in the outer drum 56. The inner drum 55 is configured to rotate with respect to the outer drum 56. The inner drum 55 has a first blowout port 57 as a blowout port. The outer drum 56 is fixed to the support groove 41. The outer drum 56 has a second blowout port 58 and a third blowout port 59 as blowout ports. The second blowout port 58 and the third blowout port 59 face different directions from each other. The second blowout port 58 faces the support surface 26. The third blowout port 59 faces the absorbent material 52.

[0062] The inner drum 55 is configured to be able to rotate by a not-illustrated switching mechanism. The not-illustrated switching mechanism includes, for example, a switching drive section that is able to be controlled by the control section 13, and a transmission mechanism that transmits the driving force of the switching drive section to the inner drum 55. The transmission mechanism can employ, for example, one or both of a transmission belt and at least one gear, in the case where a motor is employed as the switching drive section. The first blowout port 57 moves within the outer drum 56 by the inner drum 55 rotating. In the case where the first blowout port 57 overlaps the second blowout port 58, gas is blown out toward the support surface 26. In the case where the first blowout port 57 overlaps the third blowout port 59, gas is blown out toward the absorbent material 52.

[0063] In the present example, the blowing section 35 is configured to selectively blow gas toward the support surface 26 or the absorbent material 52. Thereby, the amount of gas blown per unit time is increased compared to a case in which gas is blown toward both the support surface 26 and the absorbent material 52 at the same time, under a condition in which the amount of gas from the blower 54 per unit time is substantially fixed. The blowing section 35 can also be configured to blow gas toward both the support surface 26 and the absorbent material 52. In this case, for example, the inner drum 55 can be removed from the blowing section 35. In addition to this, for example, the blowing section 35 having only one blow outlet can be disposed obliquely and blow gas toward the contact portion of the support surface 26 and the absorbent material 52, thereby blowing gas toward both the support surface 26 and the absorbent material 52.

[0064] The absorbent material 52 is dried by the blowing section 35 blowing gas toward the absorbent material 52. Thereby, the possibility that the absorbent material 52 is always soaked with the cleaning liquid is reduced. When the absorbent material 52 is always soaked and left for a long time, there is a possibility that the absorbent material 52 deteriorates. For example, there is a possibility that the absorbent material 52 molds. In particular, the portion of the absorbent material 52 that contacts the atmosphere is likely to mold. The drying of the absorbent material 52 is promoted by the blowing section 35, thereby reducing the possibility that the absorbent material 52 deteriorates. For example, when it is predicted that the conveyance device 15 will not be used for a long time, the drying of the absorbent material 52 can be promoted by the blowing section 35 blowing gas toward the absorbent material 52.

[0065] The cleaning mechanism 23 can also have a heating section 61. In other words, the recording device 11 or the conveyance device 15 can be provided with the heating section 61. The heating section 61 is configured to heat the gas blown by the blowing section 35. The heating section 61 includes, for example, a heating element. The heating section 61 is installed, for example, in the inner drum 55. The heating section 61 can also be installed on the outer drum 56. The heating section 61 is not limited to being installed on the inner drum 55 or the outer drum 56, and can be provided between the blowing section 35 and the cleaning roller 32. The gas blown by the blowing section 35 is heated by the heating section 61, and the heated gas is blown toward the absorbent material 52. Thereby, the drying of the absorbent material 52 is further promoted. The heating section 61 can also heat the gas blown toward the support surface 26. The heating section 61 can be controlled by the control section 13. For example, the control section 13 can control the temperature of the gas based on the drying conditions of the absorbent material 52.

[0066] The cleaning mechanism 23 can also have a detection section 62. In other words, the recording device 11 or the conveyance device 15 can also be provided with the detection section 62. The detection section 62 is configured to detect the amount of the cleaning liquid contained in the absorbent material 52. The detection section 62 is located at a position that contacts the absorbent material 52, i.e., at a position that contacts the surface of the absorbent material 52. The detection section 62 detects the amount of the cleaning liquid contained in the absorbent material 52, for example, by measuring the electric resistance value of the surface of the absorbent material 52. The detection section 62 transmits the detection result to the control section 13.

[0067] In the present example, the detection section 62 contacts the portion of the absorbent material 52 that has been pressed by the pressing member 33. Therefore, the detection section 62 detects the amount of the cleaning liquid contained in the portion of the absorbent material 52 that has been pressed by the pressing member 33. The detection section 62 and the pressing member 33 are provided, for example, in a manner that sandwiches the rotating shaft 51. That is, the detection section 62 is located at a position that is offset in the first direction Al with respect to the cleaning roller 32.

[0068] In the case where the state of the supply section 31 is the supply state, the control section 13 can grasp the supply condition of the cleaning liquid to the absorbent material 52 based on the detection result of the detection section 62. That is, the control section 13 can grasp whether an appropriate amount of the cleaning liquid is supplied to the absorbent material 52 at the time of cleaning the conveyance belt 22. For example, the control section 13 controls the supply amount of the cleaning liquid based on the detection result of the detection section 62. In the case where the amount of the cleaning liquid contained in the absorbent material 52 is large at the time of cleaning the conveyance belt 22, the control section 13 lowers the liquid level of the cleaning liquid stored in the storage tank 42. Thereby, the amount of the cleaning liquid supplied to the absorbent material 52 becomes small. In the case where the amount of the cleaning liquid contained in the absorbent material 52 is small at the time of cleaning the conveyance belt 22, the control section 13 raises the liquid level of the cleaning liquid stored in the storage tank 42. Thereby, the amount of the cleaning liquid supplied to the absorbent material 52 becomes large.

[0069] In the case where the state of the supply section 31 is the non-supply state, the control section 13 can grasp the drying condition of the absorbent material 52 based on the detection result of the detection section 62. For example, the control section 13 controls the drying process that promotes the drying of the absorbent material 52 by the blowing section 35, the pressing member 33, or both based on the detection result of the detection section 62. Thereby, the drying condition of the absorbent material 52 is controlled. In the present example, the drying condition of the absorbent material 52 can be controlled based on the duration of time during which the drying process is continuously performed, in addition to the detection result of the detection section 62.

[0070] The cleaning mechanism 23 can also have a brush roller 63. The brush roller 63 cleans the support surface 26 by coming into contact with the support surface 26. The brush roller 63 is rotatably supported by the support groove 41. In the present example, the brush roller 63 is in contact with the support surface 26 in the case where the cleaning roller 32 is in the contact state. The brush roller 63 is separated from the support surface 26 in the case where the cleaning roller 32 is in the non-contact state.

[0071] The brush roller 63 is arranged side by side in parallel with the cleaning roller 32. In the present example, the brush roller 63 is located at a position shifted in the first direction Al compared to the cleaning roller 32. Thus, for a certain region of the support surface 26, the brush roller 63 comes into contact with the region before the cleaning roller 32 does.

[0072] The brush roller 63 has a rotation shaft 64 and a brush 65. The rotation shaft 64 is parallel to the rotation shaft 51. The brush 65 extends radially from the rotation shaft 64 as viewed in the axial direction of the rotation shaft 64. The brush 65 is supported by the rotation shaft 64. The brush 65 rotates together with the rotation shaft 64.

[0073] In the present example, a part of the brush 65 is housed in the storage groove 42. Specifically, a lower end portion of the brush 65 is housed in the storage groove 42. Thus, the brush 65 comes into contact with the cleaning liquid stored in the storage groove 42 depending on the liquid level of the cleaning liquid stored in the storage groove 42. That is, the cleaning liquid is supplied to the brush 65. In the present example, the brush 65 comes into contact with the cleaning liquid stored in the storage groove 42 in the case where the state of the supply portion 31 is the supply state. The brush 65 does not come into contact with the cleaning liquid stored in the storage groove 42 in the case where the state of the supply portion 31 is the non-supply state. That is, in the present example, the supply state refers to a state where the cleaning liquid is supplied from the supply portion 31 to the cleaning roller 32 and the brush roller 63. The non-supply state refers to a state where the cleaning liquid is not supplied from the supply portion 31 to the cleaning roller 32 and the brush roller 63.

[0074] The brush roller 63 cleans the support surface 26 by rotating in the supply state of the supply portion 31. In the present example, the brush roller 63 is, for example, linked to the rotation of the cleaning roller 32. The brush roller 63 can also be driven to rotate by the driving portion 34. The brush roller 63 can also be driven to rotate without being linked to the cleaning roller 32 by the looping of the conveyor belt 22. The dirt of the support surface 26 is removed by the brush 65 wetted with the cleaning liquid while being in contact with the support surface 26.

[0075] In the present example, the rotation direction of the brush roller 63 is identical to the rotation direction of the cleaning roller 32. The rotation direction of the brush roller 63 can also be different from the rotation direction of the cleaning roller 32. In the present example, the brush roller 63 rotates in the same direction as the cleaning roller 32 in the contact state of the cleaning roller 32. The brush roller 63 can also rotate in the opposite direction to the cleaning roller 32 in the contact state of the cleaning roller 32. Figure 2 and Figure 3The cleaning roller 32 rotates in the counterclockwise direction. Thus, the contact resistance of the conveyance belt 22 with the brush roller 63 becomes large, and it becomes easy to remove the dirt of the conveyance belt 22.

[0076] Next, the drying process for promoting drying of the absorbent material 52 is described.

[0077] The control section 13 executes a drying process for promoting drying of the absorbent material 52 by one or both of the blowing section 35 and the pressing member 33. The control section 13 starts to implement the drying process at a predetermined period. The control section 13, for example, starts to implement a first drying process of blowing gas from the blowing section 35 to the cleaning roller 32 at a predetermined period. The control section 13, for example, starts to implement a second drying process of pressing the absorbent material 52 by the pressing member 33 in a state where the supply section 31 is in the non-supply state at a predetermined period. The control section 13, for example, starts to implement a third drying process of blowing gas from the blowing section 35 to the cleaning roller 32 and pressing the absorbent material 52 by the pressing member 33 in a state where the supply section 31 is in the non-supply state at a predetermined period. The control section 13 can also select a process to be executed from among the first drying process, the second drying process, and the third drying process.

[0078] The predetermined period is, for example, when the power of the recording device 11 or the conveyance device 15 is turned off, when the reception section 14 receives an instruction from the user to start the drying process, when a predetermined period elapses, and the like.

[0079] The control section 13 ends the drying process based on a predetermined condition. The control section 13, for example, ends the first drying process of blowing gas from the blowing section 35 to the cleaning roller 32 based on a predetermined condition. The control section 13, for example, ends the second drying process of pressing the absorbent material 52 by the pressing member 33 in a state where the supply section 31 is in the non-supply state based on a predetermined condition. The control section 13, for example, ends the third drying process of blowing gas from the blowing section 35 to the cleaning roller 32 and pressing the absorbent material 52 by the pressing member 33 in a state where the supply section 31 is in the non-supply state based on a predetermined condition.

[0080] The predetermined condition is, for example, a condition based on the detection result of the detection section 62, a condition based on the duration of the drying process, and the like. The control section 13 ends the drying process when the predetermined condition is satisfied. Thus, the control section 13 ends the drying process based on the detection result of the detection section 62, the duration of the drying process. The duration can be arbitrarily set by the user through the reception section 14, for example. The duration can also be set to an appropriate value based on the evaluation result of an experiment or simulation that is implemented in advance, for example. The control section 13 can also end the drying process when the reception section 14 receives an instruction from the user to end the drying process, when a predetermined period elapses, and the like, for example, as the predetermined condition.

[0081] First, the first drying process will be described. The control section 13 starts the first drying process illustrated in FIG. 8, for example, when the start instruction, which means that the process of blowing gas from the blowing section 35 toward the cleaning roller 32 is started, is received from the user through the reception section 14. The control section 13 starts the first drying process illustrated in FIG. 8. Figure 4

[0082] As illustrated in FIG. 8, the control section 13 switches the state of the cleaning roller 32 from the contact state to the non-contact state in step S11. In the case where the state of the cleaning roller 32 is the non-contact state at the execution time point of step S11, the state of the cleaning roller 32 is maintained as the non-contact state. The control section 13 separates the cleaning roller 32 from the support surface 26 by the moving mechanism 27. At this time, the control section 13 can switch the state of the supply section 31 from the supply state to the non-supply state. Figure 4

[0083] The control section 13 blows gas from the blowing section 35 toward the cleaning roller 32 in step S12. The control section 13 causes the inner drum 55 to rotate, and thereby causes the first blowout port 57 to overlap the third blowout port 59. Thereby, gas is blown to the cleaning roller 32. At this time, since the cleaning roller 32 is separated from the support surface 26, gas easily flows on the peripheral surface of the cleaning roller 32. Therefore, drying of the absorbent material 52 is easily promoted. As such, the blowing section 35 of the present example blows gas to the cleaning roller 32 in the state where the cleaning roller 32 is separated from the support surface 26.

[0084] Even if the blowing section 35 blows gas to the cleaning roller 32 in the contact state, drying of the absorbent material 52 is promoted. Therefore, step S11 can be skipped in the first drying process. Further, step S11 and step S12 can be simultaneously executed in the first drying process.

[0085] In the case where the state of the supply section 31 is the non-supply state, drying of the entire absorbent material 52 is promoted by blowing gas from the blowing section 35 toward the cleaning roller 32. In the case where the state of the supply section 31 is the supply state, drying of the portion of the absorbent material 52 which is not immersed in the cleaning liquid is promoted. Since the portion of the absorbent material 52 which is immersed in the cleaning liquid is difficult to contact with the atmosphere, deterioration is difficult to occur.

[0086] ​​The control section 13 determines whether or not the first predetermined condition is satisfied in step S13. The first predetermined condition is a condition for ending the first drying process. The first predetermined condition can be either a condition based on the duration of the first drying process or a condition based on the amount of cleaning liquid detected by the detection section 62. The control section 13 can determine that the first predetermined condition is satisfied, for example, in a case where the elapsed time that has passed since the start of blowing of the gas from the blowing section 35 to the cleaning roller 32 has reached the duration. That is, the control section 13 can determine that the first predetermined condition is satisfied in a case where the elapsed time that has passed since the start of execution of step S12 has reached the duration. In this case, the control section 13 counts the time at the time of execution of step S12. The control section 13 can also count the time that has passed since the time of execution of step Sll as the elapsed time. The control section 13 can determine that the first predetermined condition is satisfied, for example, in a case where the amount of cleaning liquid detected by the detection section 62 becomes equal to or less than a threshold value. In this case, the threshold value is stored in the control section 13. The threshold value is set to an appropriate value based on the evaluation results of experiments or simulations that are performed in advance, for example.

[0087] The control section 13 ends the first drying process in a case where it is determined in step S13 that the first predetermined condition is satisfied. At this time, the control section 13 ends the operation of blowing the gas from the blowing section 35 to the cleaning roller 32. The control section 13 can rotate the inner drum 55 in such a manner that the first blowout port 57 overlaps with the second blowout port 58, or in such a manner that none of the first blowout port 57, the second blowout port 58, and the third blowout port 59 overlap with each other.

[0088] The control section 13 repeats step S13 in a case where it is determined in step S13 that the first predetermined condition is not satisfied. That is, the blowing of the gas from the blowing section 35 to the cleaning roller 32 by the blowing section 35 is continued until the first predetermined condition is satisfied. The first predetermined condition can include a condition based on the duration, a condition based on the detection result of the detection section 62. In this case, the control section 13 ends the first drying process in a case where the elapsed time has reached the duration and the amount of cleaning liquid detected by the detection section 62 becomes equal to or less than the threshold value. The control section 13 can notify of an error in a case where the amount of cleaning liquid detected by the detection section 62 does not become equal to or less than the threshold value even though the elapsed time has reached the duration.

[0089] Next, the second drying process will be described. The control section 13 starts to implement the second drying process, for example, in a case where a start instruction, which means that the second drying process is started, is accepted from the user by the acceptance section 14, that is, in a case where the instruction to press the pressing member 33 against the absorbent material 52 in the state where the supply section 31 is in the non-supply state is accepted from the user by the acceptance section 14. Figure 5The second drying process. An example of an indication related to the action of the pressing member 33 pressing the absorbent material 52. The indication related to the action of the pressing member 33 pressing the absorbent material 52 can also be, for example, a value of the pressure at which the pressing member 33 presses the absorbent material 52, a value of the rotational speed of the cleaning roller 32. The control portion 13 can also control the action of the pressing member 33 pressing the absorbent material 52 based on the indication. For example, the control portion 13 can also control the pressure, the rotational speed, and the like based on the indication.

[0090] As Figure 5 The control portion 13 switches the state of the supply portion 31 from the supply state to the non-supply state in step S21. In the case where the state of the supply portion 31 is the non-supply state at the execution time point of step S21, the state of the supply portion 31 is maintained as the non-supply state. The control portion 13 switches the state of the supply portion 31 from the supply state to the non-supply state by closing the supply valve 44 and opening the discharge valve 46. At this time, the control portion 13 can also switch the state of the cleaning roller 32 from the contact state to the non-contact state. However, in the case of a structure in which the driving force of the drive source 21 is transmitted to the cleaning roller 32 via the conveyor belt 22, the control portion 13 switches the state of the cleaning roller 32 from the non-contact state to the contact state or maintains the state as the contact state. The reason for this is that, in the case where the state of the cleaning roller 32 is the non-contact state, the cleaning roller 32 cannot be caused to perform driven rotation by the drive source 21.

[0091] The control portion 13 causes the cleaning roller 32 to perform rotation by controlling the drive portion 34 in step S22. Thereby, the cleaning roller 32 is pressed by the pressing member 33. In addition, step S21 and step S22 can also be executed simultaneously in the second drying process.

[0092] In the case where the state of the cleaning roller 32 is the non-contact state in step S21, the pressing member 33 presses the absorbent material 52 in step S22 in a state in which the cleaning roller 32 is separated from the support surface 26. In this case, the rotational resistance applied to the cleaning roller 32 is reduced compared to the case where the state of the cleaning roller 32 is the contact state. Therefore, it becomes easy to press the absorbent material 52.

[0093] The control section 13 determines whether or not the second predetermined condition is satisfied in step S23. The second predetermined condition is a condition for ending the second drying process. The second predetermined condition can be either a condition based on the duration of the second drying process or a condition based on the amount of cleaning liquid detected by the detection section 62. The control section 13 can determine that the second predetermined condition is satisfied, for example, in a case where the elapsed time that has elapsed since the pressing member 33 started pressing the absorbent material 52 has reached the duration. That is, the control section 13 can determine that the second predetermined condition is satisfied in a case where the elapsed time that has elapsed since the start of step S22 has reached the duration. In this case, the control section 13 counts the time at the time of execution of step S22. The control section 13 can also count the time that has elapsed since the time of execution of step S21 as the elapsed time. The control section 13 can determine that the second predetermined condition is satisfied, for example, in a case where the amount of cleaning liquid detected by the detection section 62 is below a threshold value.

[0094] The control section 13 ends the second drying process in a case where it determines that the second predetermined condition is satisfied in step S23. At this time, the control section 13 ends the operation of the pressing member 33 pressing the absorbent material 52. The control section 13 stops the cleaning roller 32 by controlling the drive section 34.

[0095] The control section 13 repeats step S23 in a case where it determines that the second predetermined condition is not satisfied in step S23. That is, the control section 13 continues the pressing of the absorbent material 52 until the second predetermined condition is satisfied. The second predetermined condition can include a condition based on the duration and a condition based on the detection result of the detection section 62, like the first predetermined condition. The second predetermined condition can be the same as the first predetermined condition or different.

[0096] The first drying process and the second drying process can also be executed in parallel. The timing of the start can be the same or different in a case of parallel execution. The first drying process and the second drying process are started to be executed at predetermined timings and are ended with predetermined conditions.

[0097] Next, the third drying process will be described. The control section 13 starts to implement the third drying process, for example, in a case where the start instruction, which means the instruction to start the third drying process, that the blowing section 35 blows gas toward the cleaning roller 32 and the pressing member 33 presses the absorbent material 52 in the non-supply state of the supply section 31 are both accepted from the user by the acceptance section 14. Figure 6The third drying process is a process in which the first drying process and the second drying process are combined. The start instruction and the duration are one example of an instruction related to the operation of the pressing member 33 pressing the absorbent material 52. The instruction related to the operation of the pressing member 33 pressing the absorbent material 52 can also be, for example, a value of the pressure at which the pressing member 33 presses the absorbent material 52, a value of the rotational speed of the cleaning roller 32. The control portion 13 can also control the operation of the pressing member 33 pressing the absorbent material 52 on the basis of the instruction. For example, the control portion 13 can also control the pressure, the rotational speed, and the like on the basis of the instruction.

[0098] As shown in FIG. 6, the control portion 13 switches the state of the cleaning roller 32 from the contact state to the non-contact state in step S31 in the same manner as in step S11. In the case where the state of the cleaning roller 32 is the non-contact state at the execution time point of step S31, the state of the cleaning roller 32 is maintained as the non-contact state. Figure 6

[0099] The control portion 13 switches the state of the supply portion 31 from the supply state to the non-supply state in step S32 in the same manner as in step S21. In the case where the state of the supply portion 31 is the non-supply state at the execution time point of step S32, the state of the supply portion 31 is maintained as the non-supply state. The order of step S31 and step S32 can be reversed. Step S31 and step S32 can also be executed simultaneously.

[0100] The control portion 13 blows the gas from the blowing portion 35 toward the cleaning roller 32 in step S33 in the same manner as in step S12.

[0101] The control portion 13 causes the cleaning roller 32 to rotate in step S34 in the same manner as in step S22. The order of step S33 and step S34 can be reversed. Step S33 and step S34 can also be executed simultaneously. Step S31 to step S34 can also be executed simultaneously.

[0102] ​The control section 13 determines whether or not the third predetermined condition is satisfied in step S35. The third predetermined condition is a condition for ending the third drying process. The third predetermined condition can be a condition based on the duration of the third drying process or a condition based on the amount of cleaning liquid detected by the detection section 62. The control section 13 can determine that the third predetermined condition is satisfied, for example, in a case where the elapsed time that has elapsed from when the gas is blown from the blowing section 35 toward the cleaning roller 32 and the pressing of the absorbent material 52 by the pressing member 33 is started has reached the duration. That is, the control section 13 can determine that the third predetermined condition is satisfied in a case where the elapsed time that has elapsed from when both of step S33 and step S34 are executed has reached the duration. The control section 13 can determine that the third predetermined condition is satisfied, for example, in a case where the amount of cleaning liquid detected by the detection section 62 becomes equal to or less than the threshold value.

[0103] The control section 13 ends the third drying process in a case where it is determined in step S35 that the third predetermined condition is satisfied. At this time, the control section 13 ends the operation of blowing the gas from the blowing section 35 toward the cleaning roller 32 and the operation of pressing the absorbent material 52 by the pressing member 33. The control section 13 stops the cleaning roller 32 while causing the inner drum 55 to rotate in a manner in which the first blowout hole 57 does not overlap the third blowout hole 59.

[0104] The control section 13 repeats step S35 in a case where it is determined in step S35 that the third predetermined condition is not satisfied. That is, the control section 13 continues to perform the blowing of the gas from the blowing section 35 toward the cleaning roller 32 and the pressing of the absorbent material 52 by the pressing member 33. The third predetermined condition can include a condition based on the duration and a condition based on the detection result of the detection section 62, like the first predetermined condition and the second predetermined condition. The third predetermined condition can be the same as the first predetermined condition, the same as the second predetermined condition, or different from both the first predetermined condition and the second predetermined condition.

[0105] Next, the effects of the above-described embodiment will be described.

[0106] (1) The conveyance device 15 is provided with the pressing member 33 that contacts the absorbent material 52 and presses the absorbent material 52 by rotating the cleaning roller 32 in a state in which the pressing member 33 contacts the absorbent material 52. The pressing member 33 presses the absorbent material 52 in a state in which the supply section 31 is in the non-supply state.

[0107] According to the above structure, the amount of the cleaning liquid contained in the absorbent material 52 is reduced by the pressing member 33 pressing the absorbent material 52 in the state where the supply portion 31 is in the non-supply state. Thus, the cleaning roller 32 becomes easy to dry. Therefore, the possibility that the cleaning roller 32 is always wet is reduced. That is, the possibility that the degradation of the cleaning roller 32 is reduced.

[0108] (2) The pressing member 33 presses the absorbent material 52 in the state where the cleaning roller 32 is separated from the support surface 26.

[0109] According to the above structure, the rotational resistance applied to the cleaning roller 32 is reduced compared to the structure in which the absorbent material 52 is pressed in the state where the cleaning roller 32 is in contact with the support surface 26.

[0110] (3) After the process in which the pressing member 33 presses the absorbent material 52 in the state where the supply portion 31 is in the non-supply state is started to be executed, the control portion 13 ends the operation of the pressing member 33 pressing the absorbent material 52 based on a predetermined condition.

[0111] According to the above structure, since the pressing of the absorbent material 52 is ended based on the predetermined condition, the possibility that the absorbent material 52 is pressed more than necessary is reduced. When the absorbent material 52 is pressed more than necessary, the degradation of the absorbent material 52 is accelerated.

[0112] (4) In a case where the amount of the cleaning liquid detected by the detection portion 62 is equal to or less than a threshold value, the control portion 13 ends the operation of the pressing member 33 pressing the absorbent material 52.

[0113] According to the above structure, since the pressing of the absorbent material 52 is ended based on the amount of the cleaning liquid contained in the absorbent material 52, the possibility that the absorbent material 52 is pressed more than necessary is reduced.

[0114] (5) The control portion 13 controls the operation of the pressing member 33 pressing the absorbent material 52 based on an instruction related to the operation of the pressing member 33 pressing the absorbent material 52.

[0115] According to the above structure, since the operation of the pressing member 33 pressing the absorbent material 52 can be controlled based on the instruction from the user, appropriate pressing operation is performed according to the user.

[0116] (6) In a case where an elapsed time that has elapsed since the pressing member 33 starts to press the absorbent material 52 has reached a duration time, the control portion 13 ends the operation of the pressing member 33 pressing the absorbent material 52.

[0117] According to the above structure, the absorbent material 52 is pressed for the duration time set by the user. Therefore, the convenience for the user is improved.
