Detailed Implementation

[0038] 1. First Implementation Method

[0039] First, the configuration of the recording device 10 will be described. The recording device 10 of this embodiment is a serial inkjet printer that ejects liquid ink onto a medium P (e.g., paper) for recording.

[0040] Figure 1 and Figure 2 A perspective view showing the configuration of the recording device 10.

[0041] It should be noted that when the recording device 10 is positioned in the 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 up direction, and the -Z direction is the down direction. Similarly, the direction along the Y-axis is the front-back direction, with the +Y direction side being the front direction (front surface side) and the -Y direction side being the rear direction (back side). Furthermore, the direction along the X-axis is the left-right direction (width direction), with the +X direction side being the left direction and the -X direction side being the right direction.

[0042] like Figure 1 and Figure 2 As shown, the main body 12 of the device includes a generally rectangular shell 13 and a document reading device 14 disposed on the shell 13. The document reading device 14 includes a horizontal document mounting surface 15 made of transparent glass or the like for mounting the document to be read, and a document cover 16 that can cover the document mounting surface 15. The document cover 16 is configured to be able to be closed in the closed state ( Figure 1 ) and open state ( Figure 2The original document cover 16 opens and closes with a rotation axis (not shown) parallel to the X-axis along the width direction as the center of rotation. In the closed state, the original document cover 16 covers the original document placement surface 15 from above. In the open state, the original document cover 16 opens from the closed state to open the area above the original document placement surface 15.

[0043] On the outer surface of the housing 13, at the lower part of the front surface 17 which forms the front of the device body 12, a discharge port 18 is provided for discharging the medium P from the inside. Inside the discharge port 18, a stacker 19 is provided for supporting the medium P in a loading state as it is discharged from the housing 13 toward the front side.

[0044] An operation section 20, operated by the user of the recording device 10, is provided on the upper part of the front surface 17 of the housing 13. The operation section 20 is a panel that extends laterally upwards along the width direction of the X-axis. The operation section 20 includes a power button 21 operated when starting or stopping the recording device 10, and an operation button 22 operated when inputting various operation information. Additionally, a liquid crystal display 23 is provided that can display the operating status of the recording device 10, etc. The liquid crystal display 23 may also be a touch panel.

[0045] An ink supply section 25 is provided on the front surface 17 of the housing 13. The ink supply section 25 supplies ink to the recording head 32 ( Figure 3 The ink supply unit 25 includes multiple ink containers 26, etc. Each ink container 26 is a container capable of holding ink.

[0046] Next, the internal structure of the recording device 10 will be described.

[0047] like Figure 3 As shown, the recording device 10 includes a recording head 32 as a recording unit and a carriage 30 on which the recording head 32 is mounted.

[0048] The carriage 30 is supported by a guide rail 33 extending in the X-axis direction and is configured to move back and forth in the X-axis direction by a drive mechanism (not shown).

[0049] A platform 34 supporting the medium P being transported is disposed below the recording head 32.

[0050] The recording head 32 has multiple nozzles and sprays ink as droplets onto the medium P supported by the platform 34. The platform 34 is plate-shaped.

[0051] The recording device 10 has a conveyance mechanism that conveys the medium P toward the discharge port 18 from a non-illustrated paper supply section via the platen 34. Also, during movement of the carriage 30 along the X axis, an image, text, or the like is recorded on the medium P by alternately performing a recording operation in which the recording head 32 ejects droplets to perform one-pass recording and a conveyance operation in which the medium P is conveyed to the next recording position.

[0052] Note that in the present embodiment, the ink supply section 25 and the ink tank 26 are of a type that is disposed at a position different from the carriage 30, but the ink supply section 25 and the ink tank 26 can also be of a type that is detachably mounted on the carriage 30. Also, the recording device 10 is not limited to a serial type, and the recording head 32 can also be a long, line-type head that is disposed across the entire maximum width range of the medium P, and is of a line type that can eject droplets across the entire width range of the medium P.

[0053] The recording device 10 also has a maintenance section 40. The maintenance section 40 performs maintenance in order to maintain the recording head 32 in a normal state. For example, a cleaning operation in which ink and air are forcibly discharged from the recording head 32 is performed.

[0054] The maintenance section 40 has a cap 41. During a period in which the recording device 10 is not performing a recording operation, the carriage 30 is disposed at a position that deviates from a recording region during a recording operation, i.e., a home position.

[0055] The cap 41 is disposed at the home position, and is a bottomed box-shaped member. The cap 41 is movable in a direction along the Z axis by a lifting mechanism. The cap 41 is pushed against the lower surface side of the recording head 32 by rising. Thus, the cap 41 forms a closed space in a manner that covers nozzles formed in the lower surface of the recording head 32. Drying of ink within the nozzles of the recording head 32 is suppressed by the closed space.

[0056] The cap 41 is connected to a suction pump by a suction pipe. The suction pump sucks ink and air within the recording head 32 through the suction pipe by being driven in a closed space state. Thus, deteriorated ink (ink that has dried and increased in viscosity) within the recording head 32 is sucked out, and the recording head 32 is maintained (restored) in a normal state.

[0057] Also, in the maintenance section 40, in order to maintain the recording head 32 in a normal state, a flushing operation in which ink is forcibly ejected from the recording head 32 toward the cap 41 to remove deteriorated ink within the recording head 32 is performed periodically.

[0058] Ink (discharged liquid) that is discharged from the recording head 32 by maintenance such as a cleaning operation and a flushing operation is treated as waste liquid.

[0059] In addition, waste liquid is also generated during so-called borderless printing. Specifically, during recording based on the recording head 32, the ink (drainage liquid) ejected from the recording head 32 to the outer side of the end of the medium P becomes waste liquid.

[0060] As described above, the drained liquid generated inside the device body 12 is recovered by the drained liquid recovery unit 50. Furthermore, the drained liquid recovered by the drained liquid recovery unit 50 is discharged into the drained liquid receiving body 60, and the discharged drained liquid is received by the drained liquid receiving body 60.

[0061] Next, the structure of the drain recovery unit 50 will be explained.

[0062] like Figure 4 As shown, a drain recovery section 50 is disposed below the platen 34. The drain recovery section 50 is plate-shaped and large enough to support the entire platen 34. A plurality of through holes 35 are provided on the platen 34. The through holes 35 are holes that extend in the vertical direction and are used during marginless printing to guide the drain liquid (waste liquid) discarded on the outer side of the end of the medium P to the drain recovery section 50 disposed below.

[0063] like Figure 5 As shown, the drain recovery unit 50 includes a receiving section 51 for receiving drained liquid discharged from the platform 34. The receiving section 51 includes a flat section 51a having a flat surface and a wall section 51b dividing the flat section 51a, and receives the drained liquid discharged from the platform 34 through the flat section 51a divided by the wall section 51b.

[0064] Furthermore, the drain recovery section 50 has a recess 52 that is recessed downwards compared to the flat surface of the flat section 51a. The recess 52 is located at the center of the drain recovery section 50 along the X-axis. As a result, the drained liquid from the flat section 51a can easily flow into the recess 52.

[0065] The waste liquid recovery unit 50 recovers the waste liquid generated during borderless printing as waste liquid. In addition, it is not limited to this, but can also recover the waste liquid discharged during cleaning based on the maintenance unit 40 and the waste liquid discharged during rinsing by means of the cap 41 as waste liquid.

[0066] The drainage recovery unit 50 has a discharge section 55 for discharging the recovered drainage into the drainage collection body 60. In this embodiment, the discharge section 55 protrudes in the -Y direction and is provided with a groove 56 for drainage flow. The groove 56 has an elongated recess along the Y-axis. The outer dimension of the discharge section 55 along the X-axis gradually decreases in the -Y direction. In addition, the outer dimension of the discharge section 55 along the Z-axis gradually decreases in the -Y direction. That is, the outer shape of the discharge section 55 is tapered in the -Y direction. The discharge section 55 protrudes from the bottom of the recess 52 in the -Y direction. In addition, the groove 56 slopes downward in the -Y direction. As a result, the drainage can easily flow from the recess 52 toward the drainage collection body 60.

[0067] It should be noted that although the discharge section 55 in this embodiment is disposed in the central part of the discharge recovery section 50 along the X-axis, it can be disposed on the +X direction side or the -X direction side of the discharge recovery section 50.

[0068] like Figure 6 As shown, the front end of the discharge section 55 in the -Y direction is inserted into the interior of the drain collection body 60 via the connecting part 64. Since the discharge section 55 is pointed in the -Y direction, it can be easily inserted into the interior of the drain collection body 60. By inserting the discharge section 55 into the drain collection body 60 via the connecting part 64, the drained liquid can flow accurately into the drain collection body 60. The connecting part 64 is provided on the first surface 101 of the housing 62. In this embodiment, the first surface 101 is the +Y direction end face of the housing 62 when the drain collection body 60 is installed on the device body 12. Furthermore, in this embodiment, since the housing 62 of the drain collection body 60 is filled with absorbent bodies 63 to absorb the drained liquid, the groove 56 of the discharge section 55 and the absorbent bodies 63 can easily come into contact. Therefore, the drained liquid discharged through the groove 56 of the discharge section 55 is absorbed by the absorbent bodies 63.

[0069] Next, the composition of the drain collection body 60 will be explained.

[0070] The drain collection body 60 collects the drain generated inside the main body 12 of the device through the drain recovery section 50.

[0071] The drain reservoir 60 can be detached from and attached to the recording device 10 (device body 12), which is a device equipped with a drain section 55. Since there is a limit to the amount of drained liquid that can be stored in the drain reservoir 60, it is necessary to replace it with a new drain reservoir 60. Therefore, when the drained liquid in the drain reservoir 60 reaches the prescribed storage amount, the drain reservoir 60 in use is removed from the device body 12, and a new drain reservoir 60 is installed on the device body 12.

[0072] The prescribed amount of the discharge liquid in the discharge liquid storage body 60 is determined, for example, in accordance with the accumulated amount of the ink ejected from the recording head 32. If the accumulated amount of the ink ejected reaches the prescribed amount, the liquid crystal display 23 displays a message indicating that the discharge liquid storage body 60 needs to be replaced. In this case, as shown in FIG. 8, the user removes the back cover 11 attached to the back side of the device main body 12 from the device main body 12. Figure 7

[0073] Thus, as shown in FIG. 9, the discharge liquid storage body 60 is exposed. The discharge liquid storage body 60 is arranged in a state of being supported by the bottom plate portion 70. The discharge liquid storage body 60 has a grip portion 61 for being gripped by a finger. The grip portion 61 is provided on the second face 102, which is the opposite face of the first face 101 of the discharge liquid storage body 60 on which the connection portion 64 is arranged. The user can remove the discharge liquid storage body 60 from the device main body 12 by pulling it in the -Y direction in a state of having the finger hooked into the grip portion 61. Figure 8

[0074] Note that in the case of attaching the discharge liquid storage body 60 to the device main body 12, the discharge liquid storage body 60 is inserted into the device main body 12 in a state of having the connection portion 64 oriented in the +Y direction, and the discharge liquid storage body 60 is placed on the bottom plate portion 70. Then, the user attaches the back cover 11 to the back side of the device main body 12. If a new discharge liquid storage body 60 is replaced, the accumulated amount of the ink ejected from the recording head 32 is reset.

[0075] Here, the discharge liquid storage body 60 is detachable from the device main body 12. As described above, when removed from the discharge portion 55 in a state of gripping the grip portion 61 of the discharge liquid storage body 60, it is possible to grip it with the grip portion 61 on top. Since if gripped like this, the connection portion 64 becomes on the bottom, there is a concern that the discharge liquid in the discharge liquid storage body 60 will flow down from the connection portion 64 due to gravity. If the discharge liquid flows down from the connection portion 64, various problems such as contamination of the user's body, assets, and the like will occur.

[0076] Therefore, the discharge liquid storage body 60 of the present embodiment is provided with a configuration that, in a state of being removed from the device main body 12, suppresses the discharge liquid from flowing down from the connection portion 64 even in the case where the discharge liquid storage body 60 is held in any posture other than the posture in which the connection portion 64 is on the bottom.

[0077] The detailed configuration of the discharge liquid storage body 60 will be described below.

[0078] As shown in FIG. 10, the discharge liquid storage body 60 is provided with a case 62 formed of a resin material. The case 62 is a container that can store the discharge liquid. Figure 9

[0079] ​​​Furthermore, a connecting portion 64, which connects to the discharge portion 55, is disposed on a portion of the housing 62 of the drain collection body 60. The connecting portion 64 is provided on a first surface 101 that forms the end face of the housing 62 in the +Y direction. In this embodiment, the connecting portion 64 has an opening (through hole), through which the drained liquid recovered by the drain recovery portion 50 is introduced into the housing 62.

[0080] Furthermore, a cover 201 is provided on the connecting part 64.

[0081] In this embodiment, the connecting portion 64 is disposed at the center of the first surface 101 along the X-axis. It should be noted that the connecting portion 64 may not be disposed at the center of the first surface 101 along the X-axis.

[0082] Furthermore, in this embodiment, an absorbent 63 is disposed inside the housing 62. The absorbent 63 is a component that absorbs the drained liquid, such as non-woven fabric or sponge material. The absorbent 63 covers the entire interior of the housing 62. Therefore, in this embodiment, the drained liquid recovered by the drained liquid recovery unit 50 is introduced into the housing 62 through the connecting part 64, and the introduced drained liquid is absorbed and retained by the absorbent 63. By retaining the drained liquid, the flow of drained liquid can be more effectively suppressed.

[0083] like Figure 10A As shown, the drain collection body 60 includes a cover 201 that can be moved to a closed state covering the connection portion 64 and an open state opening the connection portion 64. This cover 201 can be in an open state while the housing 62 is mounted on the device body 12. Figure 10B ), and in the state of being removed from the main body 12 of the device, it is in a closed state. Figure 10C ).

[0084] In this embodiment, the cover 201 is rotatably mounted on the connecting portion 64. Specifically, it includes a plate-shaped opening / closing body 202 and a shaft 203 capable of rotating the opening / closing body 202. The opening / closing body 202 has the same size as the opening of the connecting portion 64. The shaft 203 is disposed at the -Z end of the opening / closing body 202 and extends in the direction along the X-axis. The opening / closing body 202 can be moved to open and close about the shaft 203. Thus, it is possible to move to an open state and a closed state with simple configuration.

[0085] Then, as Figure 10B As shown, when the drain collection body 60 with the cover 201 in the closed state is installed onto the device body 12, the discharge part 55 presses the opening and closing body 202 of the cover 201 in the -Y direction. As a result, the opening and closing body 202 rotates about the axis 203, and the cover 201 is opened.

[0086] Then, as Figure 10CAs shown, when the drain collection body 60 is removed from the device body 12 and the first surface 101 is facing downwards, the cover 201 is in a closed state. A weight portion 204 is provided on the side of the opening / closing body 202 opposite to the shaft 203. The weight portion 204 is thicker than the other parts of the opening / closing body 202. As a result, the weight portion 204 promotes rotational force around the shaft 203, and the cover 201 smoothly closes.

[0087] That is, in this embodiment, the cover 201 is displaced from the open state to the closed state by its own weight. As a result, no special configuration for displacing the cover 201 is required, and the configuration can be simplified.

[0088] It should be noted that during the process of moving from the open state to the closed state, the opening and closing body 202 is restricted from rotating and moving by abutting the -Z direction end of the opening and closing body 202 against the protrusion 205 provided inside the housing 62, and the closed state is maintained.

[0089] In addition, such as Figure 11 As shown, the housing 62 has a third surface 103 that intersects with the first surface 101. Furthermore, when loaded onto the device body 12 with the third surface 103 facing downwards, the inner side of the third surface 103 slopes downwards in a direction away from the connection point between the first surface 101 and the third surface 103 (in the -Y direction). Therefore, since the connecting portion 64 faces upwards compared to the other parts, when the drain collection body 60 is placed, the connecting portion 64 is positioned so as not to face downwards, thus suppressing the flow of drain fluid to the connecting portion 64.

[0090] In this embodiment, the third surface 103 is a flat surface, and a protrusion 130 is provided on the side of the third surface 103 closer to the center than the first surface 101. Specifically, a convex protrusion 130 is provided at the +Y direction end of the third surface 103 facing downward. Furthermore, when the drain receiver 60 is installed to the device body 12, the top surface of the protrusion 130 abuts against the base plate portion 70. As a result, since the drain receiver 60 is inclined downward in the -Y direction, it is possible to suppress the flow of drain liquid to the connecting portion 64. It should be noted that the drain receiver 60 can also be placed on a table or floor with the protrusion 130 facing downward. Even so, since the housing 62 is inclined downward from the first surface 101 toward the second surface 102, it is possible to suppress the flow of drain liquid to the connecting portion 64.

[0091] According to this embodiment, by providing a cover 201 on the connection portion 64, it is possible to suppress the flow of liquid from the connection portion 64.

[0092] Furthermore, when the connecting portion 64, which is likely to drain, is facing downwards, the cover portion 201 is closed, thus suppressing the draining. It should be noted that "facing downwards" refers not only to the case directly below, but also includes the case with a downward component. Additionally, the closed state is not limited to completely blocking the connecting portion 64; blocking at least a portion of the connecting portion 64 is sufficient.

[0093] It should be noted that in this embodiment, a torsion spring can also be configured to be arranged on the shaft 203 and apply force to the opening / closing body 202 towards the closed state. In this case, when the discharge part 55 is connected to the connecting part 64, the discharge part 55 overcomes the applied force of the torsion spring to move the cover part 201 from the closed state to the open state. Furthermore, when the discharge part 55 is separated from the connecting part 64, the cover part 201 moves from the open state to the closed state due to the applied force of the torsion spring. Even so, the cover part 201 can be moved with a simple configuration.

[0094] 2. Second Implementation Method

[0095] Next, the second embodiment will be described. It should be noted that the same reference numerals are used for configurations that are the same as those in the first embodiment, and repeated descriptions are omitted.

[0096] In this embodiment, the structure of the drain collection body 60A having a cover portion 211 in the connecting portion 64 will be described.

[0097] like Figure 12A and Figure 12B As shown, the drain receiver 60A has a cover 211 that can be moved to a closed state covering the connection 64 and an open state opening the connection 64. The cover 211 can be in an open state when the housing 62 is installed on the device body 12, and in a closed state when it is removed from the device body 12.

[0098] The cover portion 211 is an elastic body that covers the connecting portion 64. Furthermore, a slit 212 is provided on this elastic body. The slit 212 is a cut provided from the center point 212a of the cover portion 211 toward the outer periphery of the cover portion 211. Multiple slits 212 are formed from the center point 212a.

[0099] Since the cover 211 is an elastic body, it applies force towards the closed state. Furthermore, when the drain receiver 60A with the cover 211 in the closed state is installed onto the device body 12 (connecting the drain portion 55 to the connecting portion 64), the drain portion 55 overcomes the applied force in the cover 211 and presses the cover 211 in the -Y direction. As a result, the cover 211 deforms, displacing from the closed state to the open state. Therefore, no special structure is needed to control the opening and closing of the cover 211, simplifying the configuration.

[0100] Furthermore, when the drain collection body 60A is removed from the device body 12, the cover 211 is in a closed state. That is, by applying force based on the elastic body of the cover 211, it is moved from the open state to the closed state in conjunction with the movement of the discharge part 55.

[0101] According to this embodiment, since the cover 211 always becomes closed once the drain collection body 60A is removed from the main body 12 of the device, it is possible to suppress the flow of drain from the connection part 64.

[0102] It should be noted that the cover portion 211 of this embodiment and the rotating cover portion 201 of the first embodiment can also be used together. Specifically, the cover portion 211 is disposed on the outside of the rotating cover portion 201. This further suppresses the flow of liquid.

[0103] 3. Third Implementation Method

[0104] Next, the third embodiment will be described. It should be noted that the same reference numerals are used for configurations that are the same as those in the first embodiment, and repeated descriptions are omitted.

[0105] In this embodiment, the structure of the drain collection body 60B having a cover portion 221 in the connecting portion 64 will be described.

[0106] like Figure 13A and Figure 13B As shown, the drain collection body 60B includes a cover 221 that can be moved to a closed state covering the connection portion 64 and an open state opening the connection portion 64. This cover 221 can be in the open state while the housing 62 is mounted on the device body 12. Figure 13C ), while in the state of being removed from the main body 12 of the device, it is in the closed state.

[0107] In this embodiment, the first surface 101 of the drain collection body 60B becomes the upper surface of the housing 62 when the housing 62 is installed on the main body 12 of the device. That is, the connecting part 64 is disposed on the first surface 101, which becomes the upper surface.

[0108] In this embodiment, the cover 221 is rotatably disposed on the connecting portion 64. Specifically, it includes a plate-shaped opening / closing body 222 and a shaft 223 capable of rotating the opening / closing body 222. The opening / closing body 222 has the same size as the opening of the connecting portion 64. The shaft 223 is disposed at the -Y direction end of the opening / closing body 222 and extends in the direction along the X axis. The opening / closing body 222 can be moved to open and close about the shaft 223. Thus, it is possible to move to an open state and a closed state with simple configuration.

[0109] In addition, such as Figure 13CAs shown, when the drain liquid storage body 60B in which the lid portion 221 is in the closed state is attached to the device main body 12, the front end portion of the discharge portion 55 abuts against the lower end portion of the +Y direction of the opening and closing body 222. Thereby, the +Y direction end portion of the opening and closing body 222 moves upward around the shaft 223, and the lid portion 221 becomes in the open state. In other words, when the discharge portion 55 is connected to the connection portion 64, the discharge portion 55 overcomes the weight of the lid portion 221 to displace the lid portion 221 from the closed state to the open state. Thereby, the opening and closing operation of the lid portion 221 can be performed by a simple configuration.

[0110] In addition, as shown in FIG. 6, when the drain liquid storage body 60B is detached from the device main body 12, the lid portion 221 is in the closed state. Specifically, the closed state of the opening and closing body 222 is maintained by the lower end portion of the +Y direction of the opening and closing body 222 abutting against the abutting portion 224 disposed at the lower end portion of the +Y direction of the opening and closing body 222. That is, in the present embodiment, the lid portion 221 is displaced from the open state to the closed state by the weight thereof. Thereby, a special configuration for displacement is not needed, and the configuration can be simplified. Figure 13A Figure 13B In addition, as shown in FIG. 6, when the drain liquid storage body 60B is detached from the device main body 12, the lid portion 221 is in the closed state. Specifically, the closed state of the opening and closing body 222 is maintained by the lower end portion of the +Y direction of the opening and closing body 222 abutting against the abutting portion 224 disposed at the lower end portion of the +Y direction of the opening and closing body 222. That is, in the present embodiment, the lid portion 221 is displaced from the open state to the closed state by the weight thereof. Thereby, a special configuration for displacement is not needed, and the configuration can be simplified.

[0111] In the above, according to the present embodiment, by providing the connection portion 64 on the upper surface of the drain liquid storage body 60B, when the drain liquid storage body 60B is detached, the user is less likely to make the connection portion 64 face downward, and the dripping of the drain liquid from the connection portion 64 can be suppressed.

[0112] Note that, in the present embodiment, the configuration in which the torsion spring is disposed at the shaft 223 to apply a force to the opening and closing body 222 toward the abutting portion 224 can also be employed. In this case, when the discharge portion 55 is connected to the connection portion 64, the discharge portion 55 overcomes the applied force of the torsion spring to displace the lid portion 221 from the closed state to the open state. In addition, when the discharge portion 55 is separated from the connection portion 64, the lid portion 221 is displaced from the open state to the closed state by the applied force of the torsion spring. Even so, the lid portion 221 can be displaced by a simple configuration.

[0113] 4. Fourth Embodiment

[0114] Next, the fourth embodiment will be described. Note that the same reference numerals are assigned to the same configurations as those of the first embodiment, and the repeated description will be omitted.

[0115] In the drain liquid storage body 60C of the present embodiment, the first face 101 of the housing 62 is different in form. Specifically, as shown in FIG. 9, the first face 101 of the housing 62 is formed in a substantially rectangular shape. Figure 14A Figure 14B ​​As shown, the first surface 101 of the housing 62 in this embodiment has a first portion 111 where a connecting portion 64 and a cover portion 201 are provided, and a second portion 112 that is closer to the front than the first portion 111 when viewed from the top view of the first surface 101. That is, the first portion 111 is located in a recessed portion relative to the second portion 112, and the second portion 112 is formed as a convex shape that protrudes relative to the first portion 111. In this embodiment, the second portion 112 is provided in the +X direction and the -X direction of the connecting portion 64. As a result, since the drain fluid in the housing 62 flows towards the second portion 112, which is located further down than the connecting portion 64, even if the connecting portion 64 is held downward, the drain fluid can be suppressed from flowing down from the connecting portion 64.

[0116] Furthermore, the first surface 101 has a third portion 113 that obliquely connects the first portion 111 and the second portion 112. Specifically, with the third surface 103 of the housing 62 above and the first surface 101 below, the third portion 113 has an inclined surface that slopes downward from the first portion 111 toward the second portion 112. This allows the drain fluid to flow smoothly from the first portion 111 toward the second portion 112.

[0117] It should be noted that the third part 113 can also be a shape that connects the first part 111 and the second part 112 at right angles.

[0118] Furthermore, the drain reservoir 60C has a shape that makes it difficult to place (vertically erect) on a table or floor, for example, with the connecting portion 64 facing downwards. Specifically, the second portion 112 has a rounded corner shape. In this embodiment, when the drain reservoir 60C is viewed from the +X direction, the second portion 112 has a curved surface protruding towards the +Y direction. As a result, it becomes impossible to place it with the first surface 101 facing downwards. Therefore, since it is not placed with the connecting portion 64 facing downwards, when the drain reservoir 60 is placed, the connecting portion 64 becomes a non-downward-facing posture, which can suppress the flow of drain fluid from the connecting portion 64.

[0119] like Figure 15 As shown, the absorbent 63 is disposed within the housing 62 in a first region 121 opposite to the connecting portion 64 and a second region 122 separated from the connecting portion 64 compared to the first region 121. Furthermore, the liquid retention force of the absorbent 63 configured in the first region 121 is smaller than that of the absorbent 63 in the second region 122. The first region 121 includes a region opposite to the first portion 111, and the second region 122 includes regions opposite to the second portion 112 and the third portion 113. Therefore, in the first region 121, the fluidity of the drained liquid is increased, promoting the flow of the drained liquid from the first region 121 to the second region 122.

[0120] The liquid retention force of the absorber 63 is set according to the bubble density of the absorber 63. Specifically, the bubble density of the absorber 63 in the first region 121 is set to be lower than the bubble density of the absorber 63 in the second region 122. As a result, the lower bubble density in the first region 121 promotes the flow of liquid from the first region 121 to the second region 122 due to capillary force.

[0121] It should be noted that in this embodiment, the first absorber 63a is disposed in the first region 121, and the second absorber 63b is disposed in the second region 122. Furthermore, the bubble density of the first absorber 63a is lower than that of the second absorber 63b. By disposing of multiple absorbers 63 (first absorber 63a, second absorber 63b) with different bubble densities, the bubble density can be easily adjusted according to the region. It should also be noted that other absorbers can be disposed between the first absorber 63a and the second absorber 63b. In this case, the bubble density of the other absorber is higher than that of the first absorber 63a and lower than that of the second absorber 63b. Even so, the drained liquid can flow from the first region 121 towards the second region 122.

[0122] Next, the function and effect of the drain collection body 60 when the drain collection body 60C is removed from the main body 12 of the device will be explained.

[0123] like Figure 8 As shown, when the drain reservoir 60C is removed from the device body 12, the user pulls the drain reservoir 60C in the -Y direction while the user's finger is inserted into the handle 61. This causes the drain reservoir 60C to move in the -Y direction, disengaging the discharge portion 55 from the connecting portion 64, and the drain reservoir 60C is removed from the device body 12.

[0124] Here, when the user moves the drain collection body 60C while holding the handle 61, if the handle 61 of the drain collection body 60C is facing upwards and the connecting part 64 is facing downwards, the drain fluid inside the housing 62 may flow down from the connecting part 64 in the direction of gravity. It should be noted that the first posture is a posture in which the orientation of the connecting part 64 is not limited to the direction of gravity but includes the downward component.

[0125] However, according to this embodiment, in the first posture of the drain collection body 60C, since the second part 112 is located lower than the first part 111 where the connecting part 64 is provided, the drain fluid inside the housing 62 moves from the first part 111 to the second part 112. As a result, it is possible to suppress the drain fluid from flowing out of the connecting part 64.

[0126] Furthermore, since the first part 111 and the second part 112 are connected at an angle through the third part 113, the drain can move smoothly from the first part 111 toward the second part 112, that is, from the first region 121 toward the second region 122.

[0127] Furthermore, since absorbers 63 (first absorber 63a and second absorber 63b) are disposed inside the housing 62, the drain can move smoothly from the first region 121 toward the second region 122, and by absorbing and retaining the drain introduced through the connecting part 64, the drain can be prevented from flowing out of the connecting part 64.

[0128] Furthermore, since the second part 112 of the drain reservoir 60C has rounded corners, it becomes difficult to place the drain reservoir 60C with the first surface 101 facing downwards. Therefore, since the connecting part 64 is not placed in a downward-facing position, when the drain reservoir 60 is placed, the connecting part 64 is in a non-downward-facing position, which can prevent drain fluid from flowing out of the connecting part 64.

[0129] 5. Fifth Implementation Method

[0130] Next, the fifth embodiment will be described. It should be noted that the same reference numerals are used for configurations that are the same as those in the first embodiment, and repeated descriptions are omitted.

[0131] In the fourth embodiment of the drain collection body 60C, the second part 112 is designed with rounded corners, but it is not limited to this. In this embodiment, the second part 112 of the drain collection body 60D has an inclined surface, making it difficult to place (erect) on a table or the ground.

[0132] Specifically, such as Figure 16A As shown, when the drain reservoir 60D is viewed in the +X direction, it has an inclined surface that slopes from the -Z direction end of the second part 112 toward the +Z direction end. This makes it impossible to mount the drain reservoir 60D with the first surface 101 facing downwards. Therefore, since the connecting part 64 is not mounted downwards, when the drain reservoir 60D is mounted, the connecting part 64 is in a non-downward orientation, which can suppress the flow of drain fluid from the connecting part 64.

[0133] In addition, such as Figure 16B As shown, it can also be configured with two inclined surfaces that slope towards the +Y direction from the -Z and +Z directions of the second part 112, causing the second part 112 to protrude in the +Y direction. Even so, the same effect can be obtained.

[0134] 6. Sixth Implementation Method

[0135] Next, the sixth embodiment will be described. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and repetitive description will be omitted.

[0136] In the above-described embodiments, the protrusion 130 is provided to the third face 103, but the present application is not limited thereto. As shown in FIG. 17, for example, the liquid discharge-receiving body 60E of the present embodiment is provided with an inclined surface 131 inclined downward from the +Y direction end toward the -Y direction inside the case 62. Thereby, the inner side of the third face 103 is inclined downward, and the flow of the liquid discharge to the connection portion 64 side can be suppressed. Figure 17

[0137] Note that in the liquid discharge-receiving body 60E of the present embodiment, the inclined surface 131 inclined downward from the +Y direction end toward the -Y direction and the horizontal surface 132 provided further to the -Y direction from the -Y direction end of the inclined surface 131 are constituted, and for example, the inclined surface 131 can be formed to the -Y direction end inside the case 62 without the horizontal surface 132. Further, a recessed portion inclined downward from the first face 101 side and the third face 103 side toward the central portion can be formed.

[0138] Note that in the first to sixth embodiments, the liquid-repellent agent can be applied to the outer surface and the periphery of the lid portions 201, 211, 221 and the connection portion 64 (opening) periphery of the first face 101 of the case 62. Further, the liquid-repellent treatment can be applied. If so, since the liquid discharge seeping from the connection portion 64 spreads wet on the first face 101, the liquid discharge can be easily suppressed from falling as droplets.

[0139] Further, the shape of the grip portion 61 in the first to sixth embodiments is not limited. For example, a through-hole, a concave-convex portion, a protrusion portion, a recessed portion, or the like can be used. Further, as long as at least a portion of the shape capable of being gripped is formed in the second face 102.

[0140] Further, the liquid discharge-receiving body 60 of the above-described embodiments has been described as a configuration for receiving the liquid discharge of the waste liquid generated at the time of marginless printing and at the time of maintenance, but the present application is not limited thereto. For example, the liquid discharge-receiving body 60 can be a member capable of receiving the usable liquid discharge (for example, ink), such as an ink cartridge or the like.

[0141] The absorbent body 63 is not limited to the configuration in which the first absorbent body 63a and the second absorbent body 63b are provided and the bubble density difference is formed by the first absorbent body 63a and the second absorbent body 63b.

[0142] For example, Figure 14B ​The absorbent body 63 of the drain liquid storage body 60C shown can also be formed so that, when mounted in the case 62, the portion disposed in the second region 122 has a size in the first direction that is larger than the internal dimension of the case 62 in the first direction. Note that the first direction can be the direction along the X axis, the direction along the Y axis, or the direction along the Z axis.

[0143] In Figure 18A The example of the drain liquid storage body 60F shown is formed with an absorbent body 63 disposed in a portion of the second region 122 that has a volume in the direction along the X axis that is larger than the case 62. Note that the bubble density of the absorbent body 63 is uniformly formed. Also, as Figure 18B shown, the absorbent body 63 is stored in the case 62. Since the portion corresponding to the second region 122 is larger than the internal dimension of the case 62, if the absorbent body 63 is stored in the case 62, the portion of the absorbent body 63 corresponding to the second region 122 is pressed against the case 62. Thus, it is possible to make the bubble density in the second region 122 higher than the bubble density in the first region 121. Therefore, since it is possible to configure only one absorbent body 63 having the same bubble density, the manufacture of the drain liquid storage body 60F becomes easy.

[0144] Also, for example, as Figure 19 shown, in the drain liquid storage body 60G, the case 62 having the first face 101 extending in the X axis direction is provided with the absorbent body 63. The absorbent body 63 has a first absorbent portion 66a opposite the connection portion 64, and a second absorbent portion 66b closer to the front than the first absorbent portion 66a when viewed from the first face 101 side. Even so, since the drain liquid flows from the first absorbent portion 66a to the second absorbent portion 66b even if the connection portion 64 is made lower, it is possible to prevent the drain liquid from flowing down from the connection portion 64.

[0145] The drain liquid storage body has a case that stores drain liquid, a connection portion provided in a first face of the case and connected to the drain portion, and an absorbent body that absorbs the drain liquid, the first face having a first portion in which the connection portion is provided, and a second portion that protrudes more than the first portion in a direction intersecting the first face.

[0146] Thus, even if the connection portion is held in a downward direction, since the drain liquid in the case flows toward the second portion disposed lower than the connection portion, it is possible to prevent the drain liquid from flowing down from the connection portion.

[0147] Also, the first face can further have a third portion that connects the first portion and the second portion obliquely.

[0148] Thus, it is possible to make the drain liquid flow smoothly from the first portion to the second portion.

[0149] Also, the second portion can be a slanted surface.

[0150] Thus, the placement in a manner that the first surface is downward is suppressed. Therefore, since the connection portion is not placed in a state of facing downward, when the liquid discharge container is placed, the connection portion becomes a posture not facing downward, and the flow of the liquid discharge from the connection portion downward can be suppressed.

[0151] Also, the second portion can be a slanted surface.

[0152] Thus, the placement in a manner that the first surface is downward is suppressed. Therefore, since the connection portion is not placed in a state of facing downward, when the liquid discharge container is placed, the connection portion becomes a posture not facing downward, and the flow of the liquid discharge from the connection portion downward can be suppressed.

[0153] The housing can have a third surface intersecting the first surface, and when placed in a manner that the third surface is downward, the third surface of the inside of the housing becomes downwardly slanted as it faces a direction away from a connection position of the first surface and the third surface.

[0154] Thus, the inside of the third surface becomes downwardly slanted, and the flow of the liquid discharge to the connection portion side can be suppressed.

[0155] The third surface can have a protrusion provided on the first surface side than the center.

[0156] Thus, since the liquid discharge container is inclined toward the -Y direction downward, the flow of the liquid discharge to the connection portion side can be suppressed. Note that the liquid discharge container can be placed on a table or a floor with the protrusion of the liquid discharge container facing downward. Even so, since the housing is inclined toward the second surface downward from the first surface, the flow of the liquid discharge to the connection portion side can be suppressed.

[0157] The liquid retention force of a first region of the absorbent opposite the connection portion can be lower than a second region of the absorbent at a position separated from the connection portion than the first region.

[0158] For example, the first region includes a region opposite the first portion, and the second region includes a region opposite the second portion and the third portion. Thus, in the first region, the flowability of the liquid discharge becomes high, and the flow of the liquid discharge from the first region to the second region is promoted.

[0159] The bubble density of the first region of the absorbent can be lower than the bubble density of the second region.

[0160] The liquid retention force of the absorbent is set in accordance with the bubble density of the absorbent. Thus, by the bubble density being low in the first region, the flow of the liquid discharge from the first region to the second region side by the capillary force can be promoted.

[0161] Also, the absorbent can have a first absorbent disposed in the first region and a second absorbent disposed in the second region, the first absorbent having a lower bubble density than the second absorbent.

[0162] By disposing a plurality of absorbents (the first absorbent, the second absorbent) having different bubble densities, the bubble density difference can be easily made by region. Note that another absorbent can be disposed between the first absorbent and the second absorbent. In this case, the bubble density of the other absorbent is made higher than the bubble density of the first absorbent and lower than the bubble density of the second absorbent. In this way, the flow of the discharged liquid from the first region toward the second region can be made.

[0163] On the other hand, the absorbent can also be formed such that, when mounted in the case, the size in the first direction of the portion disposed in the second region is larger than the internal dimension of the case in the first direction.

[0164] Since the portion corresponding to the second region is larger than the internal dimension of the case, if the absorbent is housed in the case, the portion of the absorbent corresponding to the second region is pressed against the case. Thus, the bubble density in the second region can be made higher than the bubble density in the first region. Therefore, since the discharged liquid container can be constituted with only one absorbent having the same bubble density, the manufacture of the discharged liquid container becomes easy.
