It intersects the F1 direction. The emission direction F1 may be the -Y direction or a direction between the -Y direction and the +X direction. Also, the emission direction F1 may be a direction between the -Y direction, the +Z direction, and the +X direction. It is sufficient that the air is discharged to the absorbing member 60 and the discharge direction E and the discharge direction F1 intersect. Since the ejection direction E and the ejection direction F1 intersect each other, it is possible to prevent the ejected air from hitting the nozzle surface 40 in which the nozzles 36 for ejecting the liquid in the liquid ejection section 20 are opened.

The moisture evaporation promoting part 90 may have a heating part 90b capable of releasing heat to the absorbing member 60 in a releasing direction F1 that intersects with the discharging direction E. As shown in FIG. The moisture evaporation promoting part 90 may emit heat as an emission to the absorbing member 60 . The moisture evaporation promoting portion 90 accelerates moisture evaporation of the liquid absorbed by the absorbing member 60 in the moisture evaporating portion A2 of the absorbing member 60 by releasing heat.

By intersecting the ejection direction E and the ejection direction F1, it is possible to suppress the radiation of heat to the nozzle surface 40 from which the nozzles 36 for ejecting the liquid in the liquid ejection section 20 are opened.

The moisture evaporation promoting section 90 may have both an air blowing section 90 a for releasing air and a heating section 90 b for releasing heat to the absorbing member 60 . That is, the moisture evaporation promoting part 90 may emit air and heat as emitted matter to the absorbing member 60 in the emitting direction F1 that intersects with the ejection direction E.

As shown in FIG. 6 , the liquid ejecting device 11 may include an exhaust section 91 that is arranged along the moving direction D of the absorbing member 60 along with the moisture evaporation promoting section 90 . In this embodiment, the exhaust section 91 is arranged downstream of the moisture evaporation promoting section 90 in the moving direction D. As shown in FIG. It should be noted that the receiving device 43 includes an exhaust section 91 in this embodiment.

The emitted matter emitted from the moisture evaporation promoting part 90 to the absorbent member 60 hits the surface of the absorbent member 60 to evaporate the moisture from the absorbent member 60 . Therefore, the amount of moisture contained in the air near the surface of the absorbing member 60 increases. By arranging the exhaust portion 91 side by side with the moisture evaporation promoting portion 90 , air containing a large amount of moisture near the surface of the absorbing member 60 can be sucked into the exhaust portion 91 .

In this embodiment, the substance discharged from the moisture evaporation promoting section 90 is discharged in the discharge direction F1 between the -Y direction and the +Z direction. Emissions emitted in a direction between the -Y direction and the +Z direction tend to rebound in a direction between the +Y direction and the +Z direction by hitting the surface of the absorbing member 60 . By arranging the exhaust section 91 side by side on the downstream side of the moisture evaporation promoting section 90 , the rebounding emitted material can be sucked into the exhaust section 91 .

The exhaust section 91 is positioned downstream in the discharge direction F1 with respect to the blower section 90a. In the case of such a configuration, the air as the emitted substance bounces back toward the exhaust section 91 after hitting the surface of the absorbing member 60 . Since the rebounded air contains a large amount of moisture evaporated from the absorbing member 60 , the air containing a large amount of the evaporated moisture can be sucked into the exhaust section 91 .

The exhaust unit 91 is composed of, for example, a duct extending in the width direction X and having an intake opening on a wall surface on the -Y direction side, and a fan located at the end of the duct in the -X direction. As a result, the exhaust portion 91 forms an air flow in which the air near the surface of the absorbing member 60 is sucked into the duct from the suction port and the air is discharged to the side portion of the receiving device 43 . A second duct is further formed in the liquid ejecting device 11 from the side of the receiving device 43 to the outside of the liquid ejecting device 11 , so that the air discharged from the receiving device 43 can flow to the outside of the liquid ejecting device 11 . Airflow may be configured to exhaust to

The exhaust unit 91 may be arranged upstream of the moisture evaporation promoting unit 90 in the moving direction D. That is, in FIG. 6, the positions of the moisture evaporation promoting portion 90 and the exhaust portion 91 may be reversed. At that time, the substance emitted from the moisture evaporation promoting portion 90 is emitted in a direction between the -Y direction and the -Z direction. By hitting the surface of the absorbing member 60, the ejected material is likely to rebound in a direction between the +Y direction and the -Z direction. By arranging the exhaust part 91 side by side on the upstream side of the moisture evaporation promoting part 90 , it is possible to suck the rebounded substance into the exhaust part 91 .

In the width direction X, which is the direction orthogonal to the movement direction D, the moisture evaporation promoting section 90 and the exhaust section 91 may be arranged side by side. For example, the exhaust section 91 may be arranged side by side on the −X direction side of the moisture evaporation promoting section 90 . At that time, the substance emitted from the moisture evaporation promoting portion 90 is emitted in a direction between the -Y direction and the -X direction. When the emitted material hits the surface of the absorbent member 60, it rebounds in a direction between the +Y direction and the -X direction. By arranging the exhaust part 91 side by side on the −X direction side of the moisture evaporation promoting part 90 , it is possible to suck the rebounded substance into the exhaust part 91 . In addition, by arranging the exhaust section 91 side by side on the -X direction side of the moisture evaporation promoting section 90, the air sucked into the exhaust section 91 is directed to the -X direction side of the receiving device 43, Can be easily discharged. In addition, by arranging the exhaust section 91 side by side on the +X direction side of the moisture evaporation promoting section 90, the exhaust section 91 allows the air sucked into the exhaust section 91 to be directed to the +X direction side of the receiving device 43. may be discharged to the department.

As shown in FIG. 7 , the liquid ejection device 11 may include an exhaust section 91 arranged on the opposite side of the moisture evaporation promoting section 90 with respect to the absorbing member 60 . The substance emitted from the moisture evaporation promoting part 90 to the absorbent member 60 passes through the absorbent member 60 to evaporate the moisture from the absorbent member 60 . Therefore, the amount of moisture contained in the air near the surface of the absorbing member 60 increases. By arranging the exhaust portion 91 on the opposite side of the moisture evaporation promoting portion 90 with respect to the absorbing member 60 , air containing a large amount of moisture in the vicinity of the surface of the absorbing member 60 can be sucked into the exhaust portion 91 .

In this embodiment, the substance discharged from the moisture evaporation promoting section 90 is discharged in the -Y direction, i.e., the discharging direction F2, and is perpendicular to the second movement direction D2 of the absorbent member 60 in the moisture evaporation section A2. From the direction, it passes through the absorbing member 60 and goes to the exhaust section 91 .

The exhaust unit 91 includes, for example, a fan that blows air in the -Y direction. The exhaust part 91 constitutes an air flow in which the fan draws air into the exhaust part 91 from the +Y direction side and exhausts the air to the side part of the receiving device 43 that is the -Y direction side. The direction in which the exhaust unit 91 exhausts air may be the −X direction side of the receiving device 43 or the +Z direction side of the receiving device 43 downward.

<Regarding the detector that detects the amount of movement of the absorbing member>
As shown in FIG. 8, the liquid ejection device 11 may include a detection section 95 that detects the amount of movement of the absorbing member 60 . Then, the control section 29 may calculate the amount of the absorbing member 60 wound by the winding section 72 based on the detection result of the detection section 95 . In other words, the liquid ejection device 11 may include the control section 29 that calculates the amount of the absorbing member 60 wound by the winding section 72 based on the detection result of the detection section 95 . Note that in the liquid ejecting apparatus 11 shown in FIG. 8, constituent elements that are not related to receiving liquid in the absorbing member 60 and evaporating water from the absorbing member 60 are omitted.

The detection unit 95 detects the amount of rotation of one of the rollers rotated following the movement of the absorbing member 60 in the transport path between the delivery unit 70 and the winding unit 72 of the absorbing member 60. The amount of movement of the absorbing member 60 may be detected. For example, a rotary encoder that detects the amount of rotation may be provided as the detector 95 on the rotating shaft of the second horizontal roller 79 . In addition, a roller that follows the movement of the absorbing member 60 by coming into contact with the surface of the absorbing member 60 is newly provided in the conveying path between the delivery unit 70 and the winding unit 72 of the absorbing member 60. The amount of rotation may be detected by the detector 95 .

The detector 95 may detect the amount of movement of the absorbing member 60 from the amount of rotation of the winding motor 64 . In the absorbing member 60 wound around the winding shaft 71, the diameter of the wound absorbing member 60 increases as it is wound. The amount of rotation of the shaft 71 is reduced. Therefore, it is desirable that the amount of movement of the absorbing member 60 is corrected as the absorbing member 60 is wound up. The control unit 29 stores the relationship between the amount of winding onto the winding shaft 71 from the start of winding, the amount of rotation of the winding shaft 71, and the amount of movement of the absorbing member 60 as correction data. When used, the amount of movement of the absorbing member 60 can be calculated from the amount of rotation of the winding shaft 71 .

<Regarding the control method of the moisture evaporation promoting part>
First, an overview of the control method of the moisture evaporation promoting section 90 will be described.
The control unit 29 does not perform the operation of promoting evaporation of the liquid absorbed by the absorbing member 60 until the amount of the absorbing member 60 wound on the winding unit 72 exceeds a predetermined amount. When the absorbing member 60 receives the waste liquid in the receiving portion A1 by flushing, the control unit 29 transports the absorbing member 60 in the moving direction D. As shown in FIG. Then, the control unit 29 positions the portion of the absorbing member 60 that does not receive the waste liquid to the receiving portion A1. As a result, at the time of the next flushing, the waste liquid can be received by the absorbing member 60 in the portion not receiving the waste liquid.

After the amount of the absorbing member 60 wound on the winding unit 72 exceeds a predetermined amount, the control unit 29 performs an operation to accelerate evaporation of the liquid absorbed by the absorbing member 60 . When the absorbing member 60 receives the waste liquid in the receiving portion A1 by flushing, the control unit 29 transports the absorbing member 60 in the moving direction D. As shown in FIG. Then, the controller 29 positions the portion of the absorbing member 60 not receiving the waste liquid in the receiving portion A1, operates the moisture evaporation accelerating portion 90 and the exhaust portion 91, and causes the absorbing member 60 to move to the moisture evaporating portion A2. accelerates the evaporation of liquids absorbed by That is, after the amount of the absorbent member 60 wound on the winding unit 72 exceeds a predetermined amount, the control unit 29 starts promoting the evaporation of moisture by the moisture evaporation promoting unit 90 . As a result, at the time of the next flushing, the waste liquid can be received by the absorbing member 60 in the portion not receiving the waste liquid, and the liquid absorbed in the absorbing member 60, which is the portion near the outer peripheral surface when wound up, can be removed. Moisture evaporation can be accelerated.

Next, regarding the control method of the moisture evaporation promoting section 90, the control executed by the control section 29 in each step shown in the flowchart of FIG. 9 will be described in order.
In step S<b>101 , when the user replaces the absorbing member 60 with a new one, the control unit 29 starts operating the liquid ejection device 11 and starts controlling the moisture evaporation promoting unit 90 . Then, the control unit 29 shifts the process to step S102.

In step S102, the control unit 29 periodically performs flushing. After flushing, the absorbing member 60 receives the waste liquid at the receiving portion A1. Then, the control unit 29 shifts the process to step S103.

In step S103, the controller 29 moves the absorbing member 60 in the moving direction D by a predetermined amount. The predetermined amount of movement is the amount of movement for positioning the portion of the absorbing member 60 that has not received the waste liquid in the receiving portion A1. As a result, the portion of the absorbing member 60 that does not receive the waste liquid is positioned at the receiving portion A1. Then, the control unit 29 shifts the process to step S104.

In step S<b>104 , the control section 29 calculates the amount of the absorbing member 60 wound by the winding section 72 . For example, the amount of movement of the absorbing member 60 is calculated from the amount of rotation of the roller detected by the detection unit 95, and the length of the wound absorbing member 60 is calculated by integrating the amount of movement of the absorbing member 60. be done. Then, the control unit 29 shifts the process to step S105.

In step S105, the controller 29 determines whether or not the amount of the wound absorbing member 60 exceeds a predetermined amount. When the amount of the wound absorbing member 60 exceeds the predetermined amount, step S105 becomes YES, and the control section 29 shifts the process to step S106. When the amount of the wound absorbing member 60 does not exceed the predetermined amount, step S105 becomes NO, and the control section 29 shifts the process to step S102.

In step S106, the control unit 29 periodically performs flushing. After flushing, the absorbing member 60 receives the waste liquid at the receiving portion A1. Then, the control unit 29 shifts the process to step S107.

In step S107, the controller 29 moves the absorbing member 60 by a predetermined amount. The predetermined amount of movement is the amount of movement for positioning the portion of the absorbing member 60 that has not received the waste liquid in the receiving portion A1. As a result, the portion of the absorbing member 60 that does not receive the waste liquid is positioned at the receiving portion A1. Then, the control unit 29 shifts the process to step S108.

In step S<b>108 , the control section 29 calculates the amount of the absorbing member 60 wound by the winding section 72 . For example, the amount of movement of the absorbing member 60 is calculated from the amount of rotation of the roller detected by the detection unit 95, and the length of the wound absorbing member 60 is calculated by integrating the amount of movement of the absorbing member 60. be done. Then, the control unit 29 shifts the process to step S109.

In step S109, the control unit 29 operates the moisture evaporation promoting unit 90 and the exhaust unit 91 for a predetermined time. As a result, the control unit 29 causes the moisture evaporation promoting unit 90 to accelerate the moisture evaporation of the liquid absorbed by the absorbing member 60, which will be the portion near the outer peripheral surface when wound up. The control unit 29 may continue to operate the moisture evaporation promoting unit 90 and the exhaust unit 91 . In that case, the control unit 29 may stop the moisture evaporation promoting unit 90 and the exhaust unit 91 in step S111, which will be described later.

In step S110, the controller 29 determines whether or not the amount of the wound absorbing member 60 exceeds the second predetermined amount. When the amount of the wound absorbing member 60 exceeds the second predetermined amount, step S110 becomes YES, and the control section 29 shifts the process to step S111. When the amount of the wound absorbing member 60 does not exceed the second predetermined amount, step S110 becomes NO, and the control section 29 shifts the process to step S106. When the amount of the wound absorbent member 60 exceeds the second predetermined amount, it means that the end of the absorbent member 60 is near. Note that when the load of the winding motor 64 exceeds a predetermined load due to an increase in the amount of the absorbing member 60 wound by the winding unit 72, the control unit 29 controls the amount of the absorbing member 60 wound by the winding unit 72 to increase. exceeds a second predetermined amount.

In step S<b>110 , the control unit 29 notifies replacement of the absorbing member 60 . For example, a message prompting replacement of the absorbing member 60 may be displayed on the operation panel 24 . In step S<b>110 , the control unit 29 may stop the recording of the liquid ejection device 11 or prevent flushing from being performed until the absorbing member 60 is replaced with a new absorbing member 60 . Note that when the absorbing member 60 is replaced with a new absorbing member 60, this flow is started again.

Steps S102 to S106 may be omitted, and the control unit 29 may operate the moisture evaporation promoting unit 90 and the exhaust unit 91 immediately after the absorbing member 60 is replaced with a new one. That is, the control unit 29 causes the moisture evaporation promoting unit 90 to accelerate the evaporation of the liquid absorbed by the absorbing member 60 from the time when the winding unit 72 starts winding until the winding ends. good too.

The order in which steps S102 and S103 are executed and the order in which steps S107 and S108 are executed may be reversed. That is, step S102 may be performed after step S103, and step S107 may be performed after step S108. More specifically, the absorption member 60 may be left in a state where the liquid is absorbed for a while without accelerating moisture evaporation immediately after flushing. For example, when the next flushing is performed, after the absorbing member 60 is moved in the movement direction D by a predetermined movement amount in order to position the portion not receiving the waste liquid in the receiving portion A1, the absorbing member 60 absorbs the waste liquid. Evaporation of water in the liquid may be promoted by the water evaporation promoting section 90 .

The control unit 29 may operate the moisture evaporation promotion unit 90 each time the liquid is discharged from the liquid ejection unit 20 to the absorption member 60, as in the flowchart shown in FIG. 9, or may operate according to other parameters. You may switch between the case where it works and the case where it does not work. In either case, the moisture evaporation promoting section 90 may be operated for a predetermined period of time and then stopped.

For example, when the amount of liquid discharged from the liquid discharger 20 to the absorbent member 60 in one flushing is equal to or greater than a predetermined amount, the control unit 29 operates the moisture evaporation promoting unit 90 to reduce the predetermined amount. The moisture evaporation promoting section 90 may not be operated when the water temperature is below.

For example, if the control unit 29 does not accelerate the evaporation of water immediately after flushing and the absorbing member 60 is left in a state where the liquid is still absorbed, the remaining time is longer than the predetermined time. In some cases, the moisture evaporation promoting section 90 may not be operated.

For example, the control unit 29 may not operate the moisture evaporation promoting unit 90 when the ambient temperature is equal to or higher than a predetermined temperature, and may operate the moisture evaporation promoting unit 90 when the ambient temperature is below the predetermined temperature. Further, the control unit 29 may operate the moisture evaporation promoting unit 90 when the ambient humidity is equal to or higher than a predetermined humidity, and may not operate the moisture evaporation promoting unit 90 when the ambient humidity is below the predetermined humidity. The liquid ejecting apparatus 11 may be equipped with a temperature/humidity sensor for measuring ambient temperature/humidity, or the user may input the temperature/humidity through the operation panel 24 .

<About the length of the moisture evaporation promoting part>
As shown in FIG. 6, the moving direction D in which the absorbing member 60 moves in the receiving portion A1 is the first moving direction D1. The first moving direction D1 is the −Y direction in the depth direction Y in which the openings of the nozzles 36 are arranged as shown in FIG. When flushing is performed in the receiving portion A1, dots of the waste liquid discharged from the opening of the nozzle 36 are arranged on the absorbing member 60 in the first moving direction D1. The length in which the dots of the waste liquid are aligned in the first movement direction D1 is the length in the first movement direction D1 between the nozzles 36 positioned farthest in the first movement direction D1, and is the nozzle width length NW shown in FIG. is. In addition, since all the nozzles 36 on the nozzle surface 40 are within the range of the receiving portion A1 when viewed from the direction of gravity Z, the receiving portion length LA1, which is the length of the receiving portion A1 in the first movement direction D1, is the same as that of the nozzle. It is longer than the width length NW.

As shown in FIG. 6, the absorbing member 60 that has received the waste liquid in the receiving portion A1 is conveyed in the moving direction D, and moves to the moisture evaporating portion A2. The moving direction D in which the absorbent member 60 moves in the moisture evaporating section A2 is the second moving direction D2. In the moisture evaporating section A2, dots of the waste liquid discharged from the opening of the nozzle 36 are arranged on the absorbing member 60 in the second moving direction D2. The length in which the dots of the waste liquid are arranged in the second moving direction D2 is the nozzle width length NW shown in FIG.

For example, if the range of the water evaporating section A2 where the water evaporation is promoted is half the range of the receiving section A1 which has received the liquid by flushing, the water evaporation can only be promoted by half the area at a time. Because you can't, the time available to accelerate water evaporation is halved. In the present embodiment, since the range of the water evaporating portion A2 where the water evaporation is promoted is wider than the range of the receiving portion A1 which has received the liquid by flushing, a sufficient time for promoting water evaporation is ensured. be able to.

As shown in FIG. 6, the moisture evaporator length LA2, which is the length of the moisture evaporator A2 in the second movement direction D2, is greater than or equal to the nozzle width length NW shown in FIG. Therefore, the absorbing member 60 in the range that has received the liquid by flushing can be positioned within the range of the moisture evaporating section A2. That is, the moisture evaporating portion length LA2 in the moving direction D of the absorbent member 60 may be equal to or longer than the receiving portion length LA1 in the moving direction D of the absorbent member 60 .

The moisture evaporation portion length LA2 in the moving direction D of the absorbent member 60 is equal to the length of the moisture evaporation promoting portion 90 in the second moving direction D2. Therefore, the length of the moisture evaporation promoting portion 90 in the second movement direction D2 may be equal to or longer than the length in the first movement direction D1 between the nozzles 36 positioned furthest apart in the first movement direction D1.

<Regarding the reuse of absorbent materials>
The power of the winding motor 64 is transmitted to the feeding unit 70 via the power transmission mechanism 65, and the control unit 29 drives the winding motor 64 so that the feeding unit 70 winds the absorbing member 60. may be configured. Then, the control unit 29 causes the feeding unit 70 to return the portion whose moisture evaporation has been accelerated by the moisture evaporation promoting unit 90 to a position where the liquid discharged from the liquid ejecting unit 20 can be received. The liquid may be discharged again to that portion.

Moisture evaporation promoting portion 90 evaporates moisture from moisture evaporating portion A<b>2 of absorbing member 60 . As the water evaporates, the absorbent member 60 in the water evaporating portion A2 becomes ready to absorb water again. Therefore, the control section 29 unwinds the absorbent member 60 in the direction opposite to the movement direction D, thereby exposing the absorbent member 60 positioned in the moisture evaporating section A2 from the second opening 67 . At that time, the absorbent member 60 exposed from the second opening 67 can absorb the liquid again as the receiving portion A1. In other words, the absorbent member 60 used to absorb liquid can be reused.

The absorbent member 60 may be reused multiple times. Even if the moisture evaporates from the absorbent member 60, the components other than the moisture contained in the discharged liquid remain in the absorbent member 60. Therefore, the absorbent member 60 is more concentrated in the absorbent member 60 in the second absorption than in the first absorption. can absorb less water. The amount of moisture that the absorbent member 60 can absorb during the third absorption is even less. Therefore, although the number of reuses is limited, it is possible to lengthen the time until the user removes the absorbent member 60 from the receiving device 43 and replaces it.

<Action of Embodiment>
The operation of this embodiment will be described.
When performing flushing, the controller 29 moves the case 61 of the receiving device 43 to the receiving position and stops it, and moves the liquid ejector 20 to the cleaning position CP and stops it. Accordingly, in the receiving device 43 , the receiving portion A<b>1 is provided at a position capable of facing the liquid ejection portion 20 . When the control unit 29 controls the liquid ejection unit 20 to eject liquid from the nozzle 36 in the ejection direction E as flushing, the liquid ejected from the nozzle 36 can be received by the receiving portion A1.

By moving the absorbing member 60 in the movement direction D, the control unit 29 retracts the portion that has received the liquid discharged from the nozzle 36 downstream from the second opening 67 . Then, the control unit 29 exposes the upstream portion, which does not receive the liquid discharged from the nozzle 36, from the second opening 67 as the receiving portion A1. The absorbing member 60 moves from upstream to downstream. The wiping portion A3 is provided on the upstream side of the receiving portion A1 in the moving direction D. As shown in FIG. Therefore, it is possible to suppress the liquid absorbed by the absorbing member 60 from adhering to the wiping portion A3 in the receiving portion A1.

By moving the absorbing member 60 in the movement direction D, the control unit 29 positions the portion that receives the liquid discharged from the nozzle 36 in the moisture evaporating unit A2 downstream of the receiving unit A1. Thus, the moisture evaporation promoting part 90 can accelerate evaporation of the liquid absorbed by the absorbing member 60 . Note that the absorbent member 60, which is a portion near the center of the wound winding portion 72, is a portion that is difficult for the user's hand to touch. . Therefore, the control unit 29 does not have to start promoting moisture evaporation by the moisture evaporation promoting unit 90 until the amount of the absorbent member 60 wound on the winding unit 72 exceeds a predetermined amount. As a result, the power consumed by the operation of the moisture evaporation promoting section 90 can be reduced.

The range of the moisture evaporating portion A2 where the moisture evaporation promoting portion 90 accelerates the evaporation of the moisture of the absorbing member 60 is wider than the range of the receiving portion A1 which receives the liquid ejected from the liquid ejecting portion 20 . Therefore, the area of the absorbing member 60 that has received the liquid ejected from the liquid ejecting section 20 can be positioned within the area where the moisture evaporation promoting section 90 promotes the evaporation of the moisture of the absorbing member 60 .

The moisture evaporation promoting part 90 releases air and heat to the absorbing member 60 in a releasing direction F1 that intersects with the discharging direction E. As shown in FIG. Therefore, even when the position of the liquid discharger 20 is changed by reciprocating, it is possible to prevent the discharged air and heat from coming into contact with the nozzle surface 40 through which the nozzles 36 for discharging the liquid are opened. .

When the exhaust part 91 is arranged side by side with the moisture evaporation promoting part 90, the air and heat emitted from the moisture evaporation promoting part 90 to the absorbing member 60 hit the surface of the absorbing member 60, thereby Let the water evaporate from the 60. Therefore, the amount of moisture contained in the air near the surface of the absorbing member 60 increases.

The air discharged from the moisture evaporation promoting part 90 hits the absorbing member 60 , contains a large amount of moisture evaporated from the absorbing member 60 , and bounces back toward the exhaust part 91 arranged side by side with the moisture evaporation promoting part 90 . Thereby, the exhaust part 91 can suck the rebounded air containing a lot of moisture.

When the exhaust part 91 is arranged on the opposite side of the moisture evaporation promoting part 90 with respect to the absorbing member 60 , the air and heat emitted from the moisture evaporation promoting part 90 to the absorbing member 60 evaporates moisture from the absorbent member 60 by passing through. Therefore, the amount of moisture contained in the air near the surface of the absorbing member 60 increases. As a result, the exhaust section 91 can suck air containing a large amount of moisture near the surface of the absorbing member 60 from the opposite side of the moisture evaporation promoting section 90 to the absorbing member 60 .

The control unit 29 causes the feeding unit 70 to take up the absorbing member 60 , thereby returning the portion whose moisture evaporation has been promoted by the moisture evaporation promoting unit 90 to a position where the liquid discharged from the liquid ejecting unit 20 can be received. . The portion whose moisture evaporation has been accelerated by the moisture evaporation promoting section 90 is returned to a position where the liquid discharged from the liquid ejecting section 20 can be received, so that the liquid can be received multiple times at the same position. That is, the absorbent member 60 used for absorbing liquid can be reused.

When the amount of the wound absorbing member 60 exceeds the second predetermined amount, for example, the control unit 29 displays a message prompting replacement of the absorbing member 60 on the operation panel 24 and records the liquid ejection device 11 . Stop. The user then removes the absorbent member 60 from the receiving device 43 and replaces it. The control unit 29 accelerates the evaporation of the liquid absorbed by the absorbing member 60 by the moisture evaporation promoting unit 90, so that the surrounding parts and the user himself/herself are contaminated by the waste liquid that seeps out from the absorbing member 60. It can be suppressed.

<Effects of Embodiment>
Effects of the present embodiment will be described.
The receiving device 43 and the liquid ejecting device 11 of this embodiment have the following effects.

(1) The water evaporation promoting portion 90 promotes water evaporation of the liquid absorbed by the absorbent member 60 between the receiving portion A1 and the winding portion 72 . As a result, the evaporation of the liquid absorbed by the absorbent member 60 can be accelerated by the moisture evaporation promoting section 90 before the absorbent member 60 that has absorbed the liquid in the receiving section A1 is taken up by the take-up section 72 . . Therefore, when the user removes the absorbing member 60 from the receiving device 43 and replaces it with a new one, it is possible to prevent surrounding parts or the user from being contaminated by the waste liquid that seeps out from the absorbing member 60 .

(2) In the absorbing member 60, the receiving portion A1 is provided at a position capable of facing the liquid discharging portion 20. As shown in FIG. Accordingly, the absorption member 60 can easily receive the liquid discharged from the liquid discharger 20 at the receiving portion A1 facing the liquid discharger 20 .

(3) Assuming that the direction in which the liquid is ejected from the liquid ejection portion 20 is the ejection direction E, the moisture evaporation promoting portion 90 ejects air toward the absorbing member 60 in the ejection directions F1 and F2 intersecting the ejection direction E. It has a possible air blower 90a. As a result, the moisture evaporation promoting section 90 having the air blowing section 90a discharges air in the discharge directions F1 and F2 intersecting the discharge direction E. As shown in FIG. Therefore, even when the position of the liquid ejector 20 is changed by reciprocating, it is possible to prevent the emitted air from hitting the nozzle surface 40 where the nozzles 36 for ejecting the liquid are open. Therefore, it is possible to promote evaporation of the liquid absorbed by the absorbing member 60 while suppressing drying of the liquid in the nozzles 36 of the liquid ejection section 20 .

(4) Assuming that the direction in which the liquid is ejected from the liquid ejection portion 20 is the ejection direction E, the moisture evaporation promoting portion 90 releases heat to the absorbing member 60 in the ejection directions F1 and F2 intersecting the ejection direction E. It has a possible heating portion 90b. As a result, the moisture evaporation promoting section 90 having the heating section 90b releases heat in the release directions F1 and F2 intersecting the ejection direction E. As shown in FIG. Therefore, even when the position of the liquid ejecting section 20 is changed by reciprocating, it is possible to suppress the radiation of heat to the nozzle surface 40 through which the nozzles 36 for ejecting the liquid are opened. That is, it is possible to promote evaporation of the liquid absorbed by the absorbing member 60 while suppressing the drying of the liquid in the nozzles 36 of the liquid ejection section 20 .

(5) By arranging the moisture evaporation promoting part 90 in the area surrounded by the feeding part 70, the winding part 72 and the absorbing member 60, the size of the receiving device 43 can be reduced. For example, when the moisture evaporation promoting part 90 is arranged outside the area surrounded by the delivery part 70, the winding part 72 and the absorbing member 60, there is a space for arranging the moisture evaporation promoting part 90 outside the area. Additional reserves have to be made, which can lead to an increase in the size of the receiving device 43 . On the other hand, by arranging the moisture evaporation promoting part 90 in that area, the size of the receiving device 43 can be reduced.

(6) Since the receiving portion A1 capable of receiving the liquid is provided downstream of the wiping portion A3 in the moving direction D, it is possible to prevent the liquid from adhering to the wiping portion A3. That is, the liquid discharged from the liquid ejection portion 20 toward the receiving portion A1 adheres to the wiping portion A3, and the liquid absorbed by the absorbing member 60 in the receiving portion A1 moves to the wiping portion A3 due to the movement of the absorbing member 60. You can prevent it from happening.

(7) The liquid ejection device 11 further includes an exhaust section 91 arranged in parallel with the moisture evaporation promoting section 90 along the moving direction D of the absorbing member 60 . As a result, the emitted material emitted from the moisture evaporation promoting portion 90 to the absorbent member 60 hits the surface of the absorbent member 60 to evaporate the moisture from the absorbent member 60 . Therefore, the amount of moisture contained in the air near the surface of the absorbing member 60 increases. By arranging the exhaust part 91 side by side with the moisture evaporation promoting part 90 , the air containing a large amount of moisture near the surface of the absorbing member 60 is sucked into the exhaust part 91 and exhausted to the outside of the liquid ejection device 11 . becomes easier.

(8) The discharge direction F1 in which the air blower 90a discharges air includes a component in the direction in which the moisture evaporation promoting unit 90 and the exhaust unit 91 are aligned, and the exhaust unit 91 is downstream in the discharge direction F1 with respect to the blower unit 90a. located on the side. When air is discharged from the air blowing part 90a of the moisture evaporation promoting part 90, the air hits the absorbing member 60, contains a large amount of moisture evaporated from the absorbing member 60, and is arranged side by side with the moisture evaporation promoting part 90. It rebounds to the part 91 side. Since the exhaust part 91 sucks the rebounded air containing a large amount of moisture, it becomes easier to exhaust the air containing a large amount of moisture to the outside of the liquid ejection device 11 .

(9) The liquid ejection device 11 further includes an exhaust section 91 arranged on the opposite side of the moisture evaporation promoting section 90 with respect to the absorbing member 60 . As a result, the substance emitted from the moisture evaporation promoting portion 90 to the absorbent member 60 passes through the absorbent member 60 , thereby evaporating the moisture from the absorbent member 60 . Therefore, the amount of water contained in the air that has passed through the absorbing member 60 increases. By arranging the exhaust part 91 on the opposite side of the moisture evaporation promoting part 90 with respect to the absorption member 60 , the moisture-rich air that has passed through the absorption member 60 is sucked into the exhaust part 91 and the liquid ejection device 11 is discharged. It becomes easy to exhaust to the outside.

(10) The length of the moisture evaporation promoting portion 90 in the second movement direction D2 is equal to or greater than the length in the first movement direction D1 between the nozzles 36 positioned furthest apart in the first movement direction D1. That is, the absorption member 60 in the range where the liquid ejected from the liquid ejection section 20 is received in the receiving section A1 is positioned within the range of the moisture evaporation section A2 where the moisture evaporation promotion section 90 promotes evaporation of the moisture in the absorption member 60. be able to. As a result, it is possible to secure sufficient time for accelerating the evaporation of water.

(11) The control unit 29 causes the feeding unit 70 to return the portion whose moisture evaporation has been accelerated by the moisture evaporation promoting unit 90 to a position where the liquid discharged from the liquid ejecting unit 20 can be received. Drain the liquid from the part again. This allows the liquid to be received multiple times at the same location. That is, the absorbent member 60 used for absorbing liquid can be reused. By reusing the absorbent member 60, the usage efficiency of the absorbent member 60 can be improved.

(12) After the amount of the absorbent member 60 wound by the winding unit 72 exceeds a predetermined amount, the control unit 29 starts the moisture evaporation promoting unit 90 to promote moisture evaporation. As a result, power consumption can be reduced by reducing the frequency with which the control unit 29 operates the moisture evaporation promoting unit 90, and the absorption power which is a portion close to the outer peripheral surface when the winding unit 72 is wound. The amount of liquid absorbed by member 60 can be reduced. A portion close to the outer peripheral surface of the wound winding portion 72 is a portion that may be touched by the user when the user removes the absorbent member 60 from the receiving device 43 and replaces it. In other words, power consumption can be reduced, and when the user removes the absorbing member 60 from the receiving device 43 and replaces it with a new one, peripheral parts or the user himself/herself are contaminated with the waste liquid exuded from the absorbing member 60. It can be suppressed.

<Modified example of embodiment>
This embodiment can be implemented with the following modifications. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

In the liquid ejecting apparatus 11 of the present embodiment, the liquid ejecting portion 20 is a serial head that reciprocates in the width direction X, and the reciprocating motion of the liquid ejecting portion 20 in the width direction X changes the recording position and the receiving position. switch. Further, the reciprocating movement of the receiving device 43 in the depth direction Y switches between the wiping position and the receiving position. However, since the liquid ejecting portion 20 is a line head extending in the width direction X, the position of the receiving device 43 is fixed, and the liquid ejecting portion 20 of the line head reciprocates in the depth direction Y, so that the recording position can be changed. , the receiving position and the wiping position may be switched.

- The pressing part 76 may be configured to be movable in the direction Z of gravity. More specifically, the pressing portion 76 may be configured to be movable to a position where the pressing portion 76 does not come into contact with the nozzle surface 40 when the receiving device 43 reciprocates in the depth direction Y. As shown in FIG. Accordingly, the liquid ejection device 11 wipes the liquid ejection portion 20 only in one of the process of moving the case 61 from the standby position to the receiving position and the process of moving the case 61 from the receiving position to the standby position. can do. That is, the nozzle surface 40 can always be wiped in one direction.

When the direction in which the liquid is discharged from the liquid discharger 20 is defined as a discharge direction E, and the directions in which air is discharged from the air blower 90a toward the absorbing member 60 are defined as discharge directions F1 and F2, the discharge direction E and the discharge direction The angle between F1 and F2 may be 90 degrees or less. The ejection direction E is perpendicular to the nozzle surface 40 . Therefore, if the angle formed by the ejection direction E and the ejection directions F1 and F2 is 90 degrees or less, the air ejected from the moisture evaporation promoting section 90 will not flow even when the liquid ejection section 20 reciprocates and moves. , the contact with the nozzle surface 40 can be suppressed.

When the direction in which the liquid is ejected from the liquid ejection portion 20 is the ejection direction E, and the directions in which heat is released from the heating portion 90b to the absorbing member 60 are the ejection directions F1 and F2, the ejection direction E and the ejection direction The angle between F1 and F2 may be 90 degrees or less. The ejection direction E is perpendicular to the nozzle surface 40 . Therefore, if the angle formed by the ejection direction E and the ejection directions F1 and F2 is 90 degrees or less, even when the liquid ejection portion 20 is reciprocated and its position is moved, the moisture evaporation promotion portion is not attached to the nozzle surface 40. It is possible to suppress the heat emitted from 90 from being radiated.

- The length of the moisture evaporation promoting portion 90 in the width direction X may be equal to or greater than the length in the width direction X between the nozzles 36 positioned farthest in the width direction X. That is, the length in the width direction X of the portion of the absorbent member 60 where the moisture evaporation promoting portion 90 promotes evaporation of moisture may be equal to or greater than the length in the width direction X of the portion of the absorbent member 60 that receives the liquid. As a result, the absorbing member 60 in the range where the liquid ejected from the liquid ejecting portion 20 is received in the receiving portion A1 can be positioned within the range where the moisture evaporation promoting portion 90 promotes the evaporation of the moisture of the absorbing member 60 .

- With respect to the absorbent member 60, the moisture evaporation promotion part 90 may be arranged on the opposite side of the second opening 67 that exposes the absorbent member 60 when the absorbent member 60 receives liquid. That is, in the absorbing member 60, the position of the receiving portion A1 and the position of the moisture evaporating portion A2 are the same, and the moisture evaporation is promoted on the surface of the absorbing member 60 opposite to the surface on the liquid receiving side. may be done. After the absorbing member 60 has received the liquid in the flushing, the moisture evaporation promoting section 90 can promote evaporation of moisture in the absorbing member 60 while the absorbing member 60 remains in its position without moving. Furthermore, the water evaporation promoting section 90 may promote water evaporation when the case 61 is not positioned at the receiving position or when the liquid ejection section 20 is not positioned at the cleaning position CP. For example, when the liquid discharger 20 is positioned at the home position HP where capping is performed, the control unit 29 may operate the moisture evaporation promoting unit 90 to promote moisture evaporation. Also, while the liquid ejection section 20 is recording, the control section 29 may operate the moisture evaporation promoting section 90 to promote moisture evaporation. Since the liquid ejection section 20 and the moisture evaporation promoting section 90 are not facing each other, it is possible to suppress the air, heat, etc. emitted from the moisture evaporation promoting section 90 from hitting the nozzle surface 40 .

- In the receiving device 43, the moisture evaporation promoting part 90 may be arranged at the position shown in FIG. . Then, in the moisture evaporation part A2, moisture evaporation of the liquid absorbed by the absorbent member 60 may be promoted from both surfaces of the absorbent member 60 by the moisture evaporation promoting part 90 and the second moisture evaporation promoting part. . As a result, the speed at which the moisture evaporation is accelerated can be made faster than when the moisture evaporation of the liquid absorbed by the absorbent member 60 from one surface of the absorbent member 60 is accelerated. At this time, the moisture evaporation promoting section 90 may be the air blowing section 90a, and the second moisture evaporation promoting section may be the heating section 90b. Also, the moisture evaporation promoting section 90 may be the heating section 90b, and the second moisture evaporation promoting section may be the air blowing section 90a.

By providing the exhaust units 91 both upstream and downstream of the moisture evaporation promoting unit 90, air containing a large amount of moisture near the surface of the absorbing member 60 is discharged from both the upstream and downstream sides of the moisture evaporation promoting unit 90. It is sucked into the exhaust portion 91 . As a result, if the air is sucked from one side of the moisture evaporation promoting section 90, the air on the other side that has not been sucked in can be sucked into the exhaust section 91 and discharged to the outside of the machine.

The liquid ejecting device 11 is arranged at a position on the opposite side of the absorbing member 60 from the moisture evaporation promoting part 90 and the first exhaust part arranged at a position aligned with the moisture evaporation promoting part 90 along the movement direction D. and a second exhaust section. Air containing a large amount of moisture in the vicinity of the surface of the absorbing member 60 may be sucked from both surfaces of the absorbing member 60 by the first exhaust section and the second exhaust section. As a result, more air containing a large amount of moisture near the surface of the absorbing member 60 can be sucked by the two exhaust portions 91 and discharged to the outside of the machine.

- With respect to the absorbent member 60, the receiving portion A1 and the moisture evaporating portion A2 may be arranged adjacent to each other. In other words, the moisture evaporation promotion section 90 may be arranged side by side with the liquid ejection section 20 that ejects the liquid to the receiving section A1. When the controller 29 positions the portion not receiving the waste liquid in the receiving portion A1 after the flushing, the moisture evaporation accelerating portion 90 accelerates the evaporation of the portion which has just received the liquid by the flushing. can be located in the moisture evaporating section A2.

- With respect to the absorbent member 60, the receiving portion A1 and the moisture evaporating portion A2 may be arranged apart from each other by the receiving portion length LA1. When the control unit 29 positions the portion not receiving the waste liquid in the receiving portion A1 after the flushing, the moisture evaporation promoting unit 90 accelerates the evaporation of the water in the portion receiving the liquid by the flushing before the last time. can be located in the moisture evaporating section A2.

- The receiving portion A1 and the moisture evaporating portion A2 may be spaced apart by a length that is an integral multiple of the receiving portion length LA1. After the flushing, when the control unit 29 positions the portion that has not received the waste liquid in the receiving portion A1, the moisture evaporation promoting unit 90 accelerates the evaporation of the water in the portion that received the liquid by the previous flushing. It can be located in the moisture evaporating section A2 where it can be carried out.

- The control section 29 may control the position of the absorbing member 60 so that the portion of the absorbing member 60 used for wiping the nozzle surface 40 is not located in the receiving portion A1 during flushing.
The control unit 29 positions the portion of the absorbing member 60 that has been used for wiping the nozzle surface 40 in the moisture evaporating portion A2 so that the moisture evaporation promoting unit 90 wipes the nozzle surface 40 and absorbs the moisture into the absorbing member 60 . You may accelerate the water evaporation of the liquid.

The receiving device 43 is configured such that the distance between the downstream end of the receiving portion A1 and the upstream end of the wiping portion A3 is longer than the distance between the upstream end of the receiving portion A1 and the upstream end of the moisture evaporating portion A2. good too. In order to reuse the absorbent member 60, when the absorbent member 60 positioned in the moisture evaporating portion A2 is positioned in the receiving portion A1, the absorbent member 60 positioned in the receiving portion A1 is moved to the position of the wiping portion A3. can be prevented from reaching That is, even when the absorbent member 60 is reused, it is possible to prevent the liquid absorbed by the absorbent member 60 from adhering to the wiping portion A3.
