[0007] 1. First embodiment First, there will be described the configuration of the recording device 10. The recording device 10 of this embodiment is a serial type inkjet printer that performs recording by ejecting ink as a liquid onto a medium P (for example, paper). 1 and 2 are perspective views showing the configuration of a recording apparatus 10. FIG. When the recording device 10 is installed on an XY plane (horizontal plane) parallel to the X and Y axes, the direction along the Z axis is the up-down direction, the +Z direction is the upward direction, and the -Z direction is the downward direction. The direction along the Y axis is the front-to-back direction, with the +Y direction side being the forward direction (front side) and the -Y direction side being the backward direction (rear side). The direction along the X axis is the left-to-right direction (width direction), with the +X direction side being the leftward direction and the -Y direction side being the rightward direction.

[0008] 1 and 2, the device main body 12 includes a housing 13 having a substantially rectangular parallelepiped shape, and a document reading device 14 disposed on the housing 13. The document reading device 14 includes a horizontal document placement surface 15 made of transparent glass or the like on which a document to be read is placed, and a document cover 16 capable of covering the document placement surface 15. The document cover 16 is provided so as to be capable of opening and closing about an X-axis along the width direction as a rotation center between a closed state (FIG. 1) in which the document placement surface 15 is covered from above, and an open state (FIG. 2) in which the document cover 16 opens from the closed state to expose the upper area of ​​the document placement surface 15.

[0009] On the outer surface of the housing 13, a discharge port 18 for discharging the medium P from inside is provided at the bottom of a front surface 17 which is the front surface of the device main body 12. A stacker 19 is provided inside the discharge port 18 for supporting the medium P discharged from inside the housing 13 toward the front side in a placed state.

[0010] An operation unit 20 operated by a user of the recording device 10 is provided at the upper part of the front surface 17 of the housing 13. The operation unit 20 is a horizontally long panel whose longitudinal direction is the width direction along the X-axis. The operation unit 20 is provided with a power button 21 which is operated when turning the recording device 10 on or off, and operation buttons 22 which are operated when inputting various types of operation information. In addition, a liquid crystal display 23 capable of displaying the operation status of the recording device 10, etc. is provided. The liquid crystal display 23 may be a touch panel.

[0011] An ink supply unit 25 is provided on the front surface 17 of the housing 13. The ink supply unit 25 supplies ink to the recording head 32 (FIG. 3). The ink supply unit 25 includes a plurality of ink tanks 26 and the like. The ink tanks 26 are containers capable of storing ink.

[0012] Next, the internal structure of the recording device 10 will be described. As shown in FIG. 3, the recording apparatus 10 includes a recording head 32 as a recording unit, and a carriage 30 on which the recording head 32 is mounted. The carriage 30 is supported by a guide rail 33 extending in the direction along the X-axis, and is configured to be capable of reciprocating in the direction along the X-axis by a drive mechanism (not shown). Below the recording head 32, a platen 34 that supports the medium P being transported is disposed. The recording head 32 includes a plurality of nozzles, and ejects ink as droplets onto the medium P supported by the platen 34. The platen 34 is in the shape of a plate. The recording device 10 includes a transport mechanism that transports the medium P from a paper feed unit (not shown) toward the discharge port 18 via a platen 34. Then, while the carriage 30 moves along the X-axis, a recording operation in which the recording head 32 ejects droplets to perform one pass of recording and a transport operation in which the medium P is transported to the next recording position are alternately performed, whereby an image, a document, or the like is recorded on the medium P. In this embodiment, the ink supply unit 25 and the ink tank 26 are of an off-carriage type arranged at a position separate from the carriage 30, but the ink supply unit 25 and the ink tank 26 may be of an on-carriage type detachably mounted on the carriage 30. Furthermore, the recording device 10 is not limited to a serial type, and may be of a line type in which the recording head 32 is an elongated line head arranged across the entire maximum width of the medium P and can eject droplets across the entire width of the medium P at once.

[0013] The recording device 10 further includes a cleaning unit 40. The cleaning unit 40 forcibly discharges ink and air from the recording head 32 (cleaning operation) in order to keep the recording head 32 in a normal state.

[0014] The cleaning unit 40 includes a cap 41. When the recording device 10 is not performing a recording operation, the carriage 30 is located at a home position that is outside the recording area during the recording operation.

[0015] The cap 41 is disposed at a home position and is a box-shaped member with a bottom. The cap 41 can be moved in a direction along the Z axis by an elevation mechanism. When the cap 41 is elevated, it is pressed against the lower surface of the recording head 32. This causes the cap 41 to form a closed space so as to cover the nozzles formed on the lower surface of the recording head 32. This closed space can prevent the ink in the nozzles of the recording head 32 from drying out.

[0016] The cap 41 is connected to a suction pump via a suction tube. The suction pump is driven in a closed space state to suck ink and air from inside the recording head 32 via the suction tube. This sucks out deteriorated ink (ink that has dried and thickened) from inside the recording head 32, and the recording head 32 is maintained (recovered) in a normal state.

[0017] In addition, in order to keep the recording head 32 in a normal state, a flushing operation is periodically performed in which ink is forcibly ejected from the recording head 32 toward the cap 41 to expel deteriorated ink from within the recording head 32 .

[0018] The ink discharged from the recording head 32 by the cleaning operation or flushing operation is treated as waste liquid. Waste liquid is also generated during so-called borderless printing. Specifically, during recording by the recording head 32, ink ejected from the recording head 32 to the outside of the edge of the medium P becomes waste liquid. As described above, the waste liquid generated inside the apparatus body 12 is collected by the waste liquid collection section 50. The waste liquid collected by the waste liquid collection section 50 is then discharged into the waste liquid storage section 60, and the discharged waste liquid is stored in the waste liquid storage section 60.

[0019] Next, the configuration of the waste liquid storage section 60 will be described. The waste liquid storage section 60 stores the waste liquid generated inside the apparatus body 12 via the waste liquid recovery section 50 . The waste liquid storage section 60 is detachable from the device body 12. Since there is a limit to the amount of waste liquid that can be stored in the waste liquid storage section 60, it is necessary to replace it with a new waste liquid storage section 60. Therefore, when the waste liquid in the waste liquid storage section 60 reaches a specified storage amount, the waste liquid storage section 60 in use is removed from the device body 12, and a new waste liquid storage section 60 is attached to the device body 12. The specified amount of waste liquid in the waste liquid storage unit 60 is determined, for example, by the cumulative amount of ink ejected from the recording head 32. When the cumulative amount of ejected ink reaches the specified amount, a message is displayed on the liquid crystal display 23 indicating that the waste liquid storage unit 60 needs to be replaced. In this case, the user removes the rear cover 11 attached to the rear side of the device body 12 from the device body 12 as shown in FIG. 4. This exposes the waste liquid storage unit 60 as shown in FIG. 5. The waste liquid storage unit 60 is disposed in a state in which it is supported by the bottom plate portion 70. The waste liquid storage unit 60 is formed with a handle portion 61 for hooking fingers. The user can remove the waste liquid storage unit 60 from the device body 12 by pulling in the -Y direction while hooking fingers on the handle portion 61.

[0020] 6 is a partially cutaway view showing the configuration of the waste liquid storage section 60. As shown in FIG. 6, the waste liquid storage section 60 is a substantially rectangular parallelepiped and includes a frame body 62 made of a resin material, and a first absorbent body 63 housed inside the frame body 62. The first absorbent body 63 is, for example, a nonwoven fabric, and absorbs the waste liquid. The first absorbent body 63 is spread all over the inside of the frame body 62. As a result, the waste liquid is held in a state where it is absorbed by the first absorbent body 63, and when the waste liquid storage section 60 is removed from the device body 12, the waste liquid stored in the frame body 62 can be prevented from leaking out to the outside.

[0021] An opening 64 (through hole) is formed in a part of the frame 62 of the waste liquid storage section 60. In this embodiment, the opening 64 is provided on the end surface in the +Y direction of the frame 62. The waste liquid collected in the waste liquid collection section 50 is introduced into the first absorbent body 63 through the opening 64.

[0022] When attaching the waste liquid storage unit 60 to the device body 12, the waste liquid storage unit 60 is inserted into the device body 12 with the opening 64 facing the +Y direction, and the waste liquid storage unit 60 is set on the bottom plate portion 70. After that, the user attaches the rear cover 11 to the rear side of the device body 12. When a new waste liquid storage unit 60 is replaced, the accumulated amount of ink ejected from the recording head 32 is reset.

[0023] Next, the configuration of the waste liquid recovery section 50 will be described. As shown in Fig. 7, the waste liquid collection unit 50 is disposed below the platen 34. The waste liquid collection unit 50 is plate-shaped and large enough to support the entire platen 34. The platen 34 is provided with a plurality of through holes 35. The through holes 35 are holes that penetrate in the vertical direction and are used to guide waste liquid that is discarded outside the edge of the medium P during borderless printing to the waste liquid collection unit 50 disposed below.

[0024] 8, the waste liquid recovery unit 50 includes a receiving portion 51 that receives the waste liquid discharged from the platen 34. The receiving portion 51 has a flat portion 51a having a flat surface and a wall portion 51b that partitions the flat portion 51a, and receives the waste liquid discharged from the platen 34 at the flat portion 51a partitioned by the wall portion 51b.

[0025] Moreover, the waste liquid collecting section 50 has a recessed section 52 recessed below the plane of the flat section 51a. The recessed section 52 is disposed in the center of the waste liquid collecting section 50 in the direction along the X-axis. This allows the waste liquid in the flat section 51a to easily flow into the recessed section 52. The waste liquid recovery section 50 is not limited to recovering waste liquid generated during borderless printing, but can also recover, via the cap 41, waste liquid discharged during cleaning by the cleaning section 40 and waste liquid discharged during flushing.

[0026] The waste liquid collecting section 50 has a discharge section 100 that discharges the collected waste liquid to the waste liquid storage section 60. The discharge section 100 of this embodiment is provided with a groove section 101 that protrudes in the -Y direction and through which the waste liquid flows. The groove section 101 has a long and narrow recess along the Y axis. The outer shape of the discharge section 100 is gradually reduced in the dimension along the X axis toward the -Y direction. Also, the outer shape of the discharge section 100 is gradually reduced in the dimension along the Z axis toward the -Y direction. That is, the outer shape of the discharge section 100 forms a pointed shape toward the -Y direction. The discharge section 100 protrudes in the -Y direction from the bottom of the recessed section 52. Also, the groove section 101 is inclined downward toward the -Y direction. This allows the waste liquid to easily flow from the recessed section 52 toward the waste liquid storage section 60. In this embodiment, the discharge section 100 is disposed in the center of the waste liquid collection section 50 in the direction along the X-axis, but it may be disposed on the +X side or the -X side of the waste liquid collection section 50.

[0027] As shown in FIG. 9, the tip portion of the discharge part 100 in the -Y direction is inserted into the inside of the waste liquid storage part 60 through the opening 64. Since the outer shape of the discharge part 100 is pointed in the -Y direction, it can be easily inserted into the inside of the waste liquid storage part 60. By inserting the discharge part 100 into the waste liquid storage part 60, the waste liquid can be reliably poured into the waste liquid storage part 60. Since the inside of the waste liquid storage part 60 is covered with the first absorbent body 63, the groove part 101 of the discharge part 100 and the first absorbent body 63 easily come into contact with each other. As a result, the waste liquid discharged through the groove part 101 of the discharge part 100 is absorbed by the first absorbent body 63.

[0028] As described above, the waste liquid storage unit 60 is detachable from the device body 12. That is, the waste liquid storage unit 60 of the present embodiment is detachable from the discharge unit 100 of the waste liquid recovery unit 50. For this reason, for example, when the waste liquid storage unit 60 is removed from the discharge unit 100, the discharge unit 100 is exposed, and therefore, ink may drip from the discharge unit 100 until a new waste liquid storage unit 60 is attached, which may cause the inside of the device body 12 to become dirty with waste liquid. 10A, the discharge unit 100 of this embodiment has a damming unit 110 that blocks the waste liquid. As a result, while the waste liquid storage unit 60 is detached from the device body 12, the waste liquid flowing through the discharge unit 100 is temporarily stored by the damming unit 110, and dripping of the waste liquid from the discharge unit 100 can be suppressed. As a result, contamination of the inside of the device body 12 due to the waste liquid can be suppressed.

[0029] The damming portion 110 of this embodiment is provided in the groove portion 101. This allows the waste liquid to be efficiently dammed. The damming portion 110 is disposed on the tip side of the discharge portion 100 in the -Y direction. In other words, the damming portion 110 is disposed at a portion where the discharge portion 100 is inserted into the waste liquid storage portion 60.

[0030] The blocking portion 110 of this embodiment is an openable and closable valve 120. The valve 120 is composed of a first opening / closing plate 121a and a second opening / closing plate 121b. The first opening / closing plate 121a and the second opening / closing plate 121b are plate-shaped. The first opening / closing plate 121a and the second opening / closing plate 121b are flexible and are made of, for example, a rubber material or a film material. When the waste liquid storage section 60 is detached from the waste liquid collection section 50, the valve 120 is in a closed state (Figure 10A) in which the waste liquid is blocked, and when the waste liquid storage section 60 is attached to the waste liquid collection section 50, the valve 120 is in an open state (Figure 10B) in which the waste liquid is not blocked.

[0031] As shown in FIG. 10A, the first opening / closing plate 121a is disposed from one wall of the groove 101 to the center of the groove 101 in the direction along the X-axis. The second opening / closing plate 121b is disposed from the other wall of the groove 101 to the center of the groove 101 in the direction along the X-axis. A part (free end) of the first opening / closing plate 121a and a part (free end) of the second opening / closing plate 121b overlap at the center of the groove 101. As a result, the valve 120 is disposed along the X-axis with respect to the groove 101 formed along the Y-axis. Therefore, when the waste liquid storage section 60 is removed from the waste liquid recovery section 50, the valve 120 provided in the groove 101 is closed, and the waste liquid is blocked.

[0032] 10B, when the discharge part 100 is inserted into the waste liquid storage part 60, it is pressed by the first absorber 63, and the free ends of the first opening / closing plate 121a and the second opening / closing plate 121b are displaced in the +Y direction. As a result, when the waste liquid storage part 60 is attached to the waste liquid recovery part 50, the valve 120 provided in the groove part 101 is opened, allowing the waste liquid to flow. Therefore, by disposing the valve 120 in the groove 101, the flow of the waste liquid can be smoothly carried out without being impeded when the waste liquid storage unit 60 is attached. On the other hand, when the waste liquid storage unit 60 is removed, the valve 120 is in a closed state, so that the waste liquid can be reliably blocked. The opening and closing mechanism of the valve 120 may be a mechanism that utilizes the biasing force of a spring or the like.

[0033] Next, the configuration of the waste liquid holding section 71 will be described. As shown in FIG. 11, the recording device 10 includes a waste liquid holding section 71 that holds the waste liquid that has dropped from the discharge section 100 into the device body 12 when the waste liquid storage section 60 is detached from the device body 12. The waste liquid holding section 71 is provided in an area of ​​the device body 12 that faces the waste liquid storage section 60 when the waste liquid storage section 60 is attached. The waste liquid holding section 71 of this embodiment is provided on the bottom plate section 70. Thereby, for example, when the waste liquid storage section 60 is detached, the waste liquid that flows out beyond the damming section 110 and drops from the discharge section 100 to the bottom of the device body 12 can be held.

[0034] The waste liquid holding section 71 is disposed in the device body 12 so as to include a region vertically below the free end (-Y direction end) of the discharge section 100. This makes it possible to hold the waste liquid that flows out beyond the damming section 110 and drops from the free end of the discharge section 100 into the device body 12. Furthermore, the waste liquid holding section 71 is disposed so as to include a region vertically below the damming section 110. This makes it possible to hold the waste liquid that flows out beyond the damming section 110 and falls from the discharge section 100 into the device body 12 at the position where the damming section 110 is provided.

[0035] The waste liquid holding portion 71 is a recess 73 surrounded by a standing wall 72. The standing wall 72 is a wall formed in a convex shape extending upward from the upper surface of the bottom plate portion 70. This allows the waste liquid that has flowed out beyond the damming portion 110 to be held in the recess 73.

[0036] 12, the waste liquid holding section 71 may include a second absorbent body 74 that absorbs the waste liquid. The second absorbent body 74 is, for example, a nonwoven fabric. The second absorbent body 74 is disposed in a recess 73 surrounded by a standing wall 72. This allows the waste liquid that has fallen from the discharge section 100 to be absorbed by the second absorbent body 74, so that the fallen waste liquid can be more reliably held. The second absorbent body 74 can be replaced as needed.

[0037] 13, the waste liquid storage section 60 may have a third absorbent body 65 that absorbs the waste liquid held in the waste liquid holding section 71 in a region facing the waste liquid holding section 71 when the waste liquid storage section 60 is attached. The third absorbent body 65 is, for example, a nonwoven fabric. By absorbing the waste liquid in the waste liquid holding part 71 on the waste liquid storage part 60 side, the waste liquid in the waste liquid holding part 71 can be dried during the time until the waste liquid storage part 60 is attached, and the amount of waste liquid that can be absorbed by the third absorbent body 65 can be increased. In addition, the waste liquid absorbed in the third absorbent body 65 can be dried during the time from when the waste liquid storage part 60 is attached to when it is replaced. This makes it possible to prevent the waste liquid adhering to the outer surface of the waste liquid storage part 60 when the waste liquid storage part 60 is attached or detached from contaminating the bottom plate part 70, the user's fingers, the surface on which the waste liquid storage part is placed, and the like. Furthermore, since the waste liquid in the waste liquid storage part 71 can be collected by replacing the waste liquid storage part 60, maintenance such as cleaning of the waste liquid storage part 71 can be simplified.

[0038] 2. Second embodiment Next, a second embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals and the duplicated description will be omitted. In the above embodiment, the damming portion 110 is the valve 120, but the damming portion 110A in this embodiment is a blocking wall 122.

[0039] As shown in FIG. 14, the blocking wall 122 is a wall that blocks the flow of waste liquid in the discharge section 100. Specifically, the blocking wall 122 is a wall formed in a part of the groove section 101. The blocking wall 122 is formed from the bottom of the groove section 101 toward the +Z direction. The blocking wall 122 of this embodiment has a height dimension equivalent to the depth dimension of the groove section 101. The blocking wall 122 may be formed integrally with the discharge section 100, or may be formed, for example, by applying a resin material to the groove section 101. The blocking wall 122 is disposed at the -Y direction end of the discharge section 100. As a result, the flow of waste liquid flowing in the -Y direction is stopped by the blocking wall 122. Therefore, even when the waste liquid storage section 60 is detached from the device body 12, the waste liquid can be reliably blocked with a simple structure.

[0040] The position of the blocking wall 122 is not limited to the -Y end of the discharge section 100, and for example, as shown in Fig. 15, the blocking wall 122 may be located in the +Y direction from the -Y end of the discharge section 100. In this case, the same effect as above can be obtained. Furthermore, the height position of the blocking wall 122 may be lower than the top of the groove portion 101. Furthermore, a plurality of blocking walls 122 may be disposed in the groove portion 101.

[0041] 3. Third embodiment Next, a third embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals and the duplicated description will be omitted. In the second embodiment, the blocking portion 110A is the blocking wall 122, and is fixed to the groove portion 101, but is not limited to this. The blocking wall 123 of the blocking portion 110B in this embodiment is configured to be deformable. The blocking wall 123 is a plate member made of a resin material. The blocking wall 123 is formed in a part of the groove portion 101. The blocking wall 123 is disposed from the bottom of the groove portion 101 toward the +Z direction. The blocking wall 123 has a height dimension equal to the depth dimension of the groove portion 101. In addition, the lower part of the blocking wall 123 and the bottom part of the groove portion 101 are connected by a torsion spring. This allows the blocking wall 123 to deform with respect to the groove portion 101. The blocking wall 123 is biased so as to maintain a position along the Z axis.

[0042] As shown in Fig. 16A, when the waste liquid storage section 60 is removed from the device body 12, the blocking wall 123 assumes a position along the Z axis and assumes a first state in which the waste liquid is blocked. On the other hand, as shown in Fig. 16B, when the waste liquid storage section 60 is attached to the device body 12 (waste liquid recovery section 50), the blocking wall 123 is pressed in the +Y direction by the first absorber 63 of the waste liquid storage section 60, so that the tip portion of the blocking wall 123 moves in the +Y direction relative to the bottom portion of the blocking wall 123, the groove portion 101 is opened, and the blocking wall 123 assumes a second state in which the waste liquid is not blocked. As a result, since the blocking wall 123 is deformable, the flow of the waste liquid can flow smoothly without being hindered when the waste liquid storage unit 60 is attached. Also, when the waste liquid storage unit 60 is removed, the waste liquid can be reliably blocked. In addition, when the waste liquid storage section 60 is removed from the device main body 12, the posture of the blocking wall 123 is not limited to a posture along the Z axis, but may be a posture that intersects with the direction along the Z axis, i.e., a configuration in which it stands at an angle.

[0043] In the above embodiment, the discharge part 100 is provided with the groove part 101, but the present invention is not limited to this. For example, the discharge part 100 may be a pipe for discharging waste liquid. In this case, a damming part 110 or the like is disposed in the pipe. Even in this case, the same effect as above can be obtained.

[0044] In the above embodiment, the discharge part 100 of the waste liquid recovery part 50 is inserted into the waste liquid storage part 60, but this is not limiting. For example, an opening 64 may be provided in the upper part of the waste liquid storage part 60, and the discharge part 100 may be disposed at a position corresponding to the upper part of the opening 64, so that the waste liquid dripping down from the discharge part 100 is stored. Even in this case, the same effect as above can be obtained. [Explanation of symbols]
