As illustrated in FIG. 7, the wall portion 66 is provided in the body 21 in such a way as to extend in the +Z direction from a body frame 60 to be described later. As illustrated in FIG. 3, the wall portion 66 is provided at such a position that the +Y-directional end of the wall portion 66 is not exposed to the outside when the body 21 is located at the open position. In other words, of the body 21, an area portion located on the +Y-directional side with respect to the +Y-directional end of the wall portion 66 in FIG. 4 is not exposed to the outside when the body 21 is located at the open position. The wall portion 66 is provided on the −X-directional side with respect to +X-directional surface of the sliding portion 64R. The wall portion 66 is provided on the +X-directional side with respect to −X-directional surface of the sliding portion 64L.

As illustrated in FIG. 4, the wall portion 66 is provided along the Y-axis direction at a position that is on the +X-directional side with respect to the carriage 51 located at the standby position. The wall portion 66 is formed of a plate member made of metal having electric conductivity, which is an example of a metal member. The wall portion 66 is coupled to the recording-unit supporting portion 63 by means of a fastening screw 97 at a contact portion for contact with the recording-unit supporting portion 63. By this connection, the wall portion 66 is grounded via the recording-unit supporting portion 63 and the power unit 95.

The fastening screw 97 is a self-tap screw made of metal and capable of being screw-driven for fastening while producing female-screw threads in a fastening hole provided in the recording-unit supporting portion 63 by means of the own threads of the fastening screw 97. The fastening hole provided in the recording-unit supporting portion 63 is formed by burring. The fastening screw 97 is inserted into a through hole provided in the wall portion 66, and the fastening screw 97 is threadably driven into the fastening hole provided in the recording-unit supporting portion 63; as a result, the threads of the fastening screw 97 become electrically coupled to the fastening hole provided in the recording-unit supporting portion 63, and the +X-directional surface of the wall portion 66 becomes electrically coupled to the head portion of the fastening screw 97.

By this means, for example, even in a case where the wall portion 66 and the recording-unit supporting portion 63 are made of a zinc-coated steel plate having a galvanized surface, the wall portion 66 and the recording-unit supporting portion 63 are electrically coupled. The wall portion 66 may be made up of, for example, a metal member that is grounded and a member that is made of resin. In this case, the metal member of the wall portion 66 is grounded by being in contact with a grounded metal member of the recording-unit supporting portion 63.

An opening 67 is provided in the wall portion 66. The opening 67 is provided at, in the wall portion 66, a position of being exposed to the outside when the body 21 is located at the open position. The opening 67 is a rectangular through hole provided at, in the wall portion 66, a position that is on the −Z-directional side with respect to the center thereof. As illustrated in FIG. 11, in the present embodiment, the opening 67 is provided in the wall portion 66 such that its longer-side direction is along the Z-axis direction and such that its shorter-side direction is along the Y-axis direction.

As illustrated in FIGS. 3 and 4, the recording apparatus 11 includes the liquid-container-portion holding portion 65. The liquid-container-portion holding portion 65 holds the liquid container portion 40. The liquid-container-portion holding portion 65 is provided at, in the body 21, a position of being exposed to the outside when at the open position. The liquid-container-portion holding portion 65 is formed of a plate member made of metal having electric conductivity, which is an example of a metal member. As will be understood from a comparison of FIG. 4 and FIG. 8, which illustrates the body 21 with the wall portion 66 removed, the liquid-container-portion holding portion 65 has an extending portion that is along the Y-axis direction and extends from a position next to the liquid container portion 40 to a position of overlapping with the wall portion 66, which is located on the +Y-directional side. The extending portion of the liquid-container-portion holding portion 65 is located on the −X-directional side with respect to the most +X-directional surface of the wall portion 66.

The liquid-container-portion holding portion 65 is coupled to the wall portion 66 by means of a fastening screw 96 at, of the extending portion, the +Y-directional end of being in contact with the wall portion 66. By this connection, the liquid-container-portion holding portion 65 is grounded via the wall portion 66, the recording-unit supporting portion 63, and the power unit 95.

The fastening screw 96 is a self-tap screw similar to the fastening screw 97. The fastening hole provided in the liquid-container-portion holding portion 65 is formed by burring. The fastening screw 96 is inserted into a through hole provided in the wall portion 66, and the fastening screw 96 is threadably driven into the fastening hole provided in the liquid-container-portion holding portion 65; as a result, the threads of the fastening screw 96 become electrically coupled to the fastening hole provided in the liquid-container-portion holding portion 65, and the +X-directional surface of the wall portion 66 becomes electrically coupled to the head portion of the fastening screw 96.

By this means, for example, even in a case where the liquid-container-portion holding portion 65 and the wall portion 66 are made of a zinc-coated steel plate having a galvanized surface, the liquid-container-portion holding portion 65 and the wall portion 66 are electrically coupled. The liquid-container-portion holding portion 65 may be made up of, for example, a metal member that is grounded and a member that is made of resin. In this case, the metal member of the liquid-container-portion holding portion 65 is grounded by being in contact with a grounded metal member of the wall portion 66.

As illustrated in FIG. 7, the body 21 includes the body frame 60 and a slide rail 61. The body frame 60 and the slide rail 61 are formed separately from each other. The body frame 60 is mounted on the slide rail 61. The body frame 60 is not in contact with the upper surface 22A of the bottom plate 22 of the housing 20.

The body frame 60 supports various members that constitute the body 21. That is, various members that constitute the body 21 are mounted on the body frame 60. As a specific example of them, the liquid container portion 40, the waste-liquid-container attachment portion 45, the recording unit 48, the sheet feeding tray 54, the transporting portion 55, the second waste liquid receiver 59, the recording-unit supporting portion 63, the liquid-container-portion holding portion 65, the wall portion 66, and the maintenance portion 70 are mounted on the body frame 60.

The slide rail 61 supports the body frame 60. The slide rail 61 is made of resin. As illustrated in FIG. 6, the slide rail 61 is configured to slide on the upper surface 22A of the bottom plate 22 of the housing 20. The slide rail 61 is configured to slide on the upper surface 22A of the bottom plate 22 without any contact of the body frame 60 with the upper surface 22A of the bottom plate 22.

More specifically, the slide rail 61 is configured to slide on the upper surface 22A of the bottom plate 22 of the housing 20 in a state in which a bottom surface 62 of the slide rail 61 is in contact with the upper surface 22A of the bottom plate 22 of the housing 20. That is, the body 21 is configured to be changed in position in the Y-axis direction in a state of being supported over the upper surface 22A of the bottom plate 22 of the housing 20.

As illustrated in FIG. 7, the slide rail 61 includes a plurality of slide rails 61A, 61B, and 61C. Each of the plurality of slide rails 61A, 61B, and 61C extends in the Y-axis direction. The slide rail 61B and the slide rail 61C are formed integrally with each other but may be formed separately from each other. The slide rail 61A is formed separately from the slide rail 61B and the slide rail 61C but may be formed integrally therewith.

The slide rail 61A, the slide rail 61B, and the slide rail 61C are arranged next to each other in the X-axis direction. The plural slide rails 61A, 61B, and 61C are arranged in the order of the slide rail 61A, the slide rail 61B, and the slide rail 61C in the +X direction.

The slide rail 61A is disposed at a position closer to the left side surface 14 of the recording apparatus 11 than to the right side surface 15 of the recording apparatus 11. The slide rail 61B and the slide rail 61C are disposed at a position closer to the right side surface 15 of the recording apparatus 11 than to the left side surface 14 of the recording apparatus 11.

The slide rail 61A is configured to slide on the upper surface 22A of the bottom plate 22 of the housing 20 in a state in which a bottom surface 62A of the slide rail 61A is in contact with the upper surface 22A of the bottom plate 22 of the housing 20. The slide rail 61B is configured to slide on the upper surface 22A of the bottom plate 22 of the housing 20 in a state in which a bottom surface 62B of the slide rail 61B is in contact with the upper surface 22A of the bottom plate 22 of the housing 20. The slide rail 61C is configured to slide on the upper surface 22A of the bottom plate 22 of the housing 20 in a state in which a bottom surface 62C of the slide rail 61C is in contact with the upper surface 22A of the bottom plate 22 of the housing 20.

As illustrated in FIGS. 4 and 8 to 12, the recording apparatus 11 includes the maintenance portion 70. In FIG. 12, the wall portion 66 has been removed from the body 21, and the contour of the wall portion 66 is indicated by dot-dot-dash-line illustration. In addition, in FIG. 12, the position of the housing 20 when the body 21 is located at the open position is shown by the contour of the housing frame 26 indicated by dot-and-dash-line illustration.

The maintenance portion 70 performs maintenance on the liquid ejecting head 52 of the recording unit 48. The maintenance portion 70 is provided in the body 21. The maintenance portion 70 is provided between the recording area RA and the wall portion 66 in the X-axis direction. The maintenance portion 70 is provided between the liquid container portion 40 and the power unit 95 of the housing 20 in the Y-axis direction. The maintenance portion 70 includes a cap 71 and a pump unit 72.

As illustrated in FIG. 12, when the body 21 is located at the open position with removal of the wall portion 66 from the body 21, the maintenance portion 70 is exposed, and, for example, the user is able to access the maintenance portion 70 from the +X-directional side. In other words, the wall portion 66 is provided at a position where it hides at least a part of the maintenance portion 70 including the pump unit 72 as viewed in the direction along the X axis. When the body 21 is located at the open position, the +Z-directional side above the maintenance portion 70 is covered by the carriage 51 located at the standby position and by the recording-unit supporting portion 63.

Driven by a non-illustrated cap movement mechanism, the cap 71 is configured to move between a capping position where it forms a capping space, toward which the nozzles are open, by being in contact with the nozzle surface of the liquid ejecting head 52 and a distanced position, which is located on the −Z-directional side with respect to the capping position. As illustrated in FIGS. 9 and 10, the cap 71 has a recessed portion open in the +Z direction and forming the capping space when at the capping position. A porous member configured to retain ink is provided in the recessed portion of the cap 71. As illustrated in FIG. 12, the cap 71 is provided at a position where it is hidden by the wall portion 66 as viewed in the direction along the X axis.

The maintenance portion 70 performs capping by movement of its cap 71 to the capping position when recording operation is not performed by the recording unit 48. By performing the capping, the maintenance portion 70 suppresses evaporation of solvent components of ink from the nozzles of the liquid ejecting head 52 and adhesion of foreign objects to the nozzle surface, thereby performing maintenance on the liquid ejecting head 52.

In addition, when flushing, in which ink is ejected from the nozzles of the liquid ejecting head 52, is performed for the purpose of a maintenance on the liquid ejecting head 52, the maintenance portion 70 causes the cap 71 to move to a position between the capping position and the distanced position so that the ink discharged as a waste liquid by the flushing will be collected into the cap 71. The flushing is operation of ejecting ink from the nozzles of the liquid ejecting head 52 at a timing different from that of ink ejection for recording, thereby discharging any of foreign objects, air bubbles, and thickened ink that are present inside the liquid ejecting head 52 and might cause poor ejection.

Moreover, the maintenance portion 70 performs suction cleaning of discharging ink from the nozzles by causing negative pressure to act on the nozzles via the pump unit 72 in a state in which the cap 71 is located at the capping position. The maintenance portion 70 performs the suction cleaning to discharge any of foreign objects, air bubbles, and thickened ink that are present inside the liquid ejecting head 52 and inside supply flow passages providing connection between the liquid ejecting head 52 and the liquid container portion 40, thereby performing maintenance on the liquid ejecting head 52 and the supply flow passages.

The pump unit 72 collects the waste liquid discharged from the recording unit 48 in the maintenance of the recording unit 48. The pump unit 72 includes a suction pump 73 and a tube T. As illustrated in FIG. 12, the suction pump 73 is provided at a position where a part of it is hidden by the wall portion 66 as viewed in the direction along the X axis. The suction pump 73 according to the present embodiment is a so-called tube pump that sucks ink into the tube T and discharges the ink out of the tube T by rotating on its axial center in a state in which the tube T is compressed by a roller. The tube T includes a first tube 74 and a second tube 75 that are illustrated in FIG. 10. As illustrated in FIG. 10, the pump unit 72 includes a waste liquid tube 76 and a tube joint 77.

As illustrated in FIG. 10, the first tube 74 provides connection between the cap 71 and the tube joint 77. The first tube 74 includes a first flowing-in portion 74h, through which, by driving of the suction pump 73, ink received by the cap 71 flows toward the suction pump 73, and a first flowing-out portion 74d, through which the ink flows from the suction pump 73 toward the tube joint 77. The cap 71 is an example of a first waste liquid receiver.

The second tube 75 provides connection between the second waste liquid receiver 59 and the tube joint 77. The second tube 75 includes a second flowing-in portion 75h, through which, by driving of the suction pump 73, ink received by the second waste liquid receiver 59 flows toward the suction pump 73, and a second flowing-out portion 75d, through which the ink flows from the suction pump 73 toward the tube joint 77.

In FIG. 10, each of the +Y-directional edge position and the −Y-directional edge position of the opening 67 in the Y-axis direction is indicated by a dot-dot-dash line. Between these two dot-dot-dash lines, the second tube 75 is located between the wall portion 66 and the first tube 74 in the X-axis direction. In addition, between these two dot-dot-dash lines, the first flowing-in portion 74h, the first flowing-out portion 74d, the second flowing-in portion 75h, and the second flowing-out portion 75d are provided along the Y-axis direction.

Moreover, between these two dot-dot-dash lines, the first flowing-in portion 74h, the first flowing-out portion 74d, the second flowing-in portion 75h, and the second flowing-out portion 75d are arranged in the order of the second flowing-in portion 75h, the second flowing-out portion 75d, the first flowing-in portion 74h, and the first flowing-out portion 74d as viewed in the −X direction from the wall portion 66. In this case, the second flowing-in portion 75h of the second tube 75 is provided next to the wall portion 66 in the X-axis direction. Moreover, as illustrated in FIG. 12, the wall portion 66 is provided at a position where it hides at least a part of the first tube 74 and the second tube 75 constituting the pump unit 72 as viewed in the direction along the X axis.

Moreover, as illustrated in FIG. 11, when viewed in the direction along the X axis from the +X-directional side of the wall portion 66, the second flowing-in portion 75h of the second tube 75 is visible through the opening 67. In other words, of the second tube 75, an area portion located inside the opening 67 as viewed in the direction along the X axis is provided next to the wall portion 66 in the X-axis direction. Furthermore, of the second flowing-in portion 75h of the second tube 75, an area portion located inside the opening 67 as viewed in the direction along the X axis extends substantially along the Y-axis direction.

For example, a tool for pinching and closing the second tube 75, a so-called pair of tube forceps, is inserted through the opening 67 in the processes of manufacturing the recording apparatus 11 and at the time of maintenance performed by the maintenance portion 70. For this reason, for easier insertion of the pair of tube forceps, for easier grasping of the second tube 75 between the tube forceps, and with ease of the user's accessing the maintenance portion 70 including the pump unit 72 and other factors considered, the opening 67 is provided in the wall portion 66 such that its longer-side direction is along the Z-axis direction and such that its shorter-side direction is along the Y-axis direction. That is, the opening 67 is provided in the wall portion 66 at a position of overlapping with the second tube 75 as viewed in the direction along the X axis and in an orientation in which the longer-side direction of the opening 67 intersects with the direction in which the second tube 75 extends. In the present embodiment, for example, the size Dn of the opening 67 in the longer-side direction is set to be 25 mm and the size Dm thereof in the shorter-side direction is set to be 10 mm.

As illustrated in FIGS. 10 and 12, the tube joint 77 is a so-called three-pronged joint to which three tubes can be coupled. The first flowing-out portion 74d of the first tube 74, the second flowing-out portion 75d of the second tube 75, and the waste liquid tube 76 are coupled to the tube joint 77, and this enables the ink received by the cap 71 and the ink received by the second waste liquid receiver 59 to be collected via the waste liquid tube 76 into the waste liquid container 46 attached to the waste-liquid-container attachment portion 45.

For example, when the body 21 is located at the open position with removal of the wall portion 66 from the body 21, the tube joint 77 is exposed, and, for example, the user is able to access the tube joint 77 from the +X-directional side. In the present embodiment, as illustrated in FIG. 12, a top edge 66t, which is the +Z-directional edge, of the wall portion 66 is located on the +Z-directional side, which is above the tube joint 77. In other words, the wall portion 66 is provided at a position where it hides the tube joint 77, which is a component of the pump unit 72, as viewed in the direction along the X axis. Therefore, the tube joint 77 is not exposed when the body 21 is located at the open position. For this reason, for example, it is possible to prevent the user from accessing the tube joint 77 from the +X-directional side. The tube joint 77 is an example of a coupler.

As illustrated in FIGS. 9, 10, and 12, the waste liquid tube 76 provides connection between the tube joint 77 and an inlet provided on the waste-liquid-container attachment portion 45. Ink flows through the inlet into the waste liquid container 46 attached to the waste-liquid-container attachment portion 45. Therefore, by driving of the suction pump 73, the ink received by the cap 71 is collected through the first tube 74, the tube joint 77, the waste liquid tube 76, and the inlet into the waste liquid container 46 as a waste liquid. In addition, by driving of the suction pump 73, the ink received by the second waste liquid receiver 59 is collected through the second tube 75, the tube joint 77, the waste liquid tube 76, and the inlet into the waste liquid container 46 as a waste liquid. As illustrated in FIG. 12, the waste liquid tube 76 is provided at a position where a part of it is hidden by the wall portion 66 as viewed in the direction along the X axis.

As illustrated in FIG. 7, the recording apparatus 11 includes a circuit board 90. The circuit board 90 is provided in the body 21. A control unit 91 is provided on the circuit board 90. The control unit 91 includes a non-illustrated central processing unit (CPU) and a non-illustrated memory. The CPU is capable of running various programs stored in the memory, and, for example, is capable of making various kinds of determination and giving various instructions. Various programs such as, for example, a program for transporting a medium and a program regarding a display method of displaying the status of the recording apparatus 11 on the display unit 35 of the operation panel 33 are stored in the memory. In addition, various tables of setting values to be used for calculating an amount of the waste liquid contained in the waste liquid container 46, various counter values, and the like are stored in the memory.

The control unit 91 controls the entire operation of the recording apparatus 11. For example, when recording is performed on a medium, the control unit 91 controls the recording unit 48 and the transporting portion 55 and cause them to execute the recording by ejecting ink from the nozzles of the liquid ejecting head 52 onto the medium transported on the medium supporting portion 53. In addition, for example, the control unit 91 performs maintenance on the liquid ejecting head 52 of the recording unit 48 by controlling either the cap movement mechanism or the suction pump 73 of the maintenance portion 70. Moreover, the control unit 91 causes the operation panel 33 to display information about the status of the recording apparatus 11 on the display unit 35.

As described above, the following effects can be obtained from the recording apparatus 11 according to the first embodiment.

The pump unit 72 includes a tube T through which the waste liquid flows. The wall portion 66 has an opening 67 at a position of overlapping with at least a part of the pump unit 72 as viewed in the direction along the X axis intersecting with the Y-axis direction. The opening 67 is located at a position of overlapping with the tube T as viewed in the direction along the X axis. With this structure, it is possible to prevent the user from touching the pump unit 72 while making it possible to perform maintenance on the pump unit 72 by making it easier to access the tube T through the opening 67.

The tube T includes a first tube 74 coupled to a cap 71 that receives the waste liquid when the maintenance of the recording unit 48 is performed and a second tube 75 coupled to a second waste liquid receiver 59 that receives the waste liquid when the recording is performed. The first tube 74 and the second tube 75 are coupled by a tube joint 77. The wall portion 66 extends from the body 21 in a +Z direction. A top edge 66t of the wall portion 66 is on a +Z-directional side with respect to the tube joint 77. With this structure, it is possible to prevent the user from touching the tube joint 77. Therefore, it is possible to prevent the occurrence of a problem such as the leakage of the waste liquid.

The tube T includes a first tube 74 coupled to a cap 71 that receives the waste liquid when the maintenance of the recording unit 48 is performed and a second tube 75 coupled to a second waste liquid receiver 59 that receives the waste liquid when the recording is performed. Of the second tube 75, an area portion located inside the opening 67 as viewed in the direction along the X axis is provided next to the wall portion 66 in the X-axis direction. With this structure, it is possible to prevent the user from touching the maintenance portion 70 while making it possible to discharge the waste liquid from the pump unit 72 in a state in which the second tube 75 is closed by means of a tool or the like by making it easier to access the second tube 75 through the opening 67.

The tube T includes a first tube 74 coupled to a cap 71 that receives the waste liquid when the maintenance of the recording unit 48 is performed and a second tube 75 coupled to a second waste liquid receiver 59 that receives the waste liquid when the recording is performed. The opening 67 is provided in the wall portion 66 at a position of overlapping with the second tube 75 as viewed in the direction along the X axis and in an orientation in which a longer-side direction of the opening 67 intersects with a direction in which the second tube 75 extends. With this structure, it is possible to make it easier to close the second tube 75 by means of a tool or the like and prevent the user from touching the maintenance portion 70.

The body 21 includes a sliding portion 64R, 64L configured to slide on the housing 20 when changed in position in the Y-axis direction. This structure makes it easier to change the position of the body 21 in the Y-axis direction.

Although the recording apparatus 11 according to the foregoing embodiment of the present disclosure has basically the structure described above, of course, partial changes in structure, omission, etc. can be made within a range of not departing from the gist of the present disclosure. The foregoing embodiment and other embodiments described below may be combined with one another as long as they are not technically contradictory to one another. Other embodiments will now be explained.

In the foregoing embodiment, the opening 67 of the wall portion 66 does not necessarily have to be a rectangular through hole, as long as a tool, etc. for putting the second tube 75 into a closed state can be inserted through it. For example, the opening 67 may be a round through hole, an elliptical through hole, or a polygonal through hole such as a triangular through hole.

In the foregoing embodiment, of the second flowing-in portion 75h of the second tube 75, an area portion located inside the opening 67 as viewed in the direction along the X axis does not necessarily have to extend along the Y-axis direction. For example, it may extend along the Z-axis direction, or in an oblique direction intersecting with the Y-axis direction and the Z-axis direction.

In the foregoing embodiment, the maintenance portion 70 may include an on-off valve configured to switch the second flowing-in portion 75h of the second tube 75 between a closed state and an open state, for example, an on-off valve configured to switch it between a closed state and an open state with a screwdriver. In this case, the opening 67 of the wall portion 66 may have any size as long as it is large enough for insertion of the screwdriver. For example, the opening 67 of the wall portion 66 may be a round through hole having a diameter of 5 mm.

In the foregoing embodiment, the wall portion 66 does not necessarily have to have the opening 67. In this case, for example, a through hole through which a tool, etc. for putting the second tube 75 into a closed state can be inserted may be provided in the body frame 60 of the body 21 at a position located on the −Z-directional side with respect to the second flowing-in portion 75h of the second tube 75.

In the foregoing embodiment, the wall portion 66 does not necessarily have to be grounded via the recording-unit supporting portion 63. For example, the wall portion 66 may be grounded by coupling the wall portion 66 and the power unit 95 by using a different grounding member as done via the recording-unit supporting portion 63.

In the foregoing embodiment, the liquid-container-portion holding portion 65 does not necessarily have to be grounded via the wall portion 66. For example, the liquid-container-portion holding portion 65 may be grounded by coupling the liquid-container-portion holding portion 65 and the power unit 95 by using a different grounding member as done via the recording-unit supporting portion 63.
