[0009] An embodiment of a liquid ejection device including a storage device will be described below with reference to the drawings. The liquid ejection device is, for example, an inkjet printer that prints images such as characters and photographs by ejecting ink, which is an example of a liquid, onto a medium such as paper or fabric.

[0010] <Liquid discharge device> As shown in Fig. 1, the liquid ejection device 11 includes a storage device 12. The storage device 12 stores various components. In one example, the storage device 12 is a printing device that prints an image. The storage device 12 will be described in detail later.

[0011] The liquid ejection device 11 may include a reading device 13. The reading device 13 is configured to read an image recorded on a document. The reading device 13 is a scanner. The reading device 13 sequentially reads images, for example, by automatically feeding a document set thereon. The reading device 13 is mounted on the storage device 12. The reading device 13 is mounted on the upper part of the storage device 12, for example.

[0012] The liquid ejection device 11 includes an operation unit 14. The operation unit 14 is an interface that allows a user to operate the liquid ejection device 11. The operation unit 14 is, for example, a touch panel. The operation unit 14 may include a button, a lever, a switch, and the like. The operation unit 14 is located, for example, in front of the storage device 12 and the reading device 13.

[0013] <Containment Device> The storage device 12 will now be described. 1 and 2, the storage device 12 has a housing 15. The housing 15 houses various components of the storage device 12. The housing 15 has a rectangular parallelepiped shape. The housing 15 has a depth, a width, and a height. The housing 15 has multiple surfaces, such as a front surface, a rear surface, and side surfaces.

[0014] The housing 15 has a frame 16. The frame 16 is made of, for example, metal. The housing 15 has one or more covers 17. The covers 17 are attached to the frame 16. The covers 17 are made of, for example, resin. The covers 17 are attached to the frame 16 so as to cover the frame 16.

[0015] An attachment opening 18 opens in the housing 15. In one example, the attachment opening 18 opens on the front surface of the housing 15. The attachment opening 18 opens toward the front. The attachment opening 18 may open on the rear surface of the housing 15 or on a side surface. In one example, the attachment opening 18 opens in the frame 16. Therefore, the attachment opening 18 is exposed by removing the cover 17 from the frame 16. The attachment opening 18 may open in the cover 17. The housing 15 is configured so that a mounting unit 31, which will be described later, can be removed from the housing 15 through the attachment opening 18. The housing 15 is configured so that the mounting unit 31 can be attached to the housing 15 through the attachment opening 18.

[0016] A maintenance port 19 opens in the housing 15. In one example, the maintenance port 19 opens in a side surface of the housing 15. The maintenance port 19 opens toward the side. The maintenance port 19 may open in the front surface, rear surface, or top surface of the housing 15. In one example, the maintenance port 19 opens in the frame 16. Therefore, the maintenance port 19 is exposed by removing the cover 17 from the frame 16. The maintenance port 19 may open in the cover 17. The housing 15 is configured to be accessible to the connection body through the maintenance port 19. The maintenance port 19 may be a common opening with the mounting port 18. In other words, the housing 15 may be configured to be accessible to the connection body through the mounting port 18. The connection body is connected to the mounting unit 31. At least a portion of the connection body has flexibility. Therefore, the connection body can follow the mounting unit 31. The connection body will be described later.

[0017] As shown in FIG. 3, the storage device 12 has a storage section 21. The storage section 21 is configured to store the medium M1. For example, a plurality of media M1 are stored in a stacked state in the storage section 21. The storage section 21 is attached to the housing 15. The storage section 21 is located at a lower part within the housing 15. In one example, the storage section 21 is configured to be insertable and removable from the housing 15. The storage section 21 is, for example, a cassette. The storage section 21 is insertable and removable from, for example, the front surface of the housing 15. A user can refill the storage section 21 with media M1 by pulling the storage section 21 out of the housing 15. The storage section 21 is not limited to a cassette, and may be a tray.

[0018] The storage device 12 has a transport path 22. The transport path 22 is a path along which the medium M1 is transported. The transport path 22 extends within the housing 15. The transport path 22 extends from the storage unit 21 toward the outside of the housing 15. An image is printed on the medium M1 while it is transported along the transport path 22.

[0019] The storage device 12 has a transport unit 23. The transport unit 23 is configured to transport the medium M1. The transport unit 23 transports the medium M1 stored in the storage unit 21. The transport unit 23 transports the medium M1 along the transport path 22. The transport unit 23 has one or more rollers 24. In one example, the transport unit 23 has a plurality of rollers 24. The plurality of rollers 24 are located along the transport path 22. The plurality of rollers 24 transport the medium M1 by rotating respectively.

[0020] The storage device 12 has a support section 25. The support section 25 is configured to support the medium M1. The support section 25 supports the medium M1 transported from the storage section 21. The support section 25 supports the medium M1 transported on the transport path 22. In one example, the support section 25 supports the medium M1 in a position that is oblique to the horizontal. The support section 25 supports the medium M1 by adsorbing it. This stabilizes the position of the medium M1. The support section 25 may support the medium M1 in a horizontal position.

[0021] The support unit 25 may be configured to transport the medium M1. In one example, the support unit 25 has a conveyor belt 26, a first pulley 27, and a second pulley 28. The conveyor belt 26 is wound around the first pulley 27 and the second pulley 28. The conveyor belt 26 attracts the medium M1 by, for example, electrostatic force. As a result, the conveyor belt 26 supports the medium M1. The conveyor belt 26 may be configured to attract the medium M1 by, for example, negative pressure due to suction. The first pulley 27 and the second pulley 28 rotate, and the conveyor belt 26 rotates. As a result, the medium M1 supported by the conveyor belt 26 is transported. The conveyor belt 26 transports the medium M1, for example, obliquely upward. The support unit 25 may be a simple support stand.

[0022] The storage device 12 has a stacker 29. The stacker 29 receives the medium M1 that is discharged outside the housing 15 through the transport path 22. The medium M1 on which an image is printed is stacked on the stacker 29. The stacker 29 is attached to the housing 15.

[0023] The storage device 12 has a main body 61. The main body 61 is located inside the housing 15. The main body 61 is connected to a connector. The main body 61 is connected to the mounting unit 31 through the connector. The main body 61 will be described later.

[0024] 4 and 5, the storage device 12 has a mounting unit 31. The mounting unit 31 is mounted to the housing 15. The mounting unit 31 is attached to and detached from the housing 15 through the mounting port 18. In one example, the mounting unit 31 is inserted and detached from the front surface of the housing 15.

[0025] The mounting unit 31 is configured to move in one direction. The one direction is a direction from inside the housing 15 to outside the housing 15 through the mounting opening 18. The mounting unit 31 is removed from the housing 15 through the mounting opening 18 by moving in one direction. In one example, the mounting unit 31 is configured to move in a first direction D1. The first direction D1 is a direction from the rear to the front of the housing 15.

[0026] The mounting unit 31 is configured to move in the opposite direction. The opposite direction is a direction opposite to the one direction. The opposite direction is a direction from outside the housing 15 toward inside the housing 15 through the mounting opening 18. The mounting unit 31 is mounted in the housing 15 through the mounting opening 18 by moving in the opposite direction. In one example, the mounting unit 31 is configured to move in a second direction D2. The second direction D2 is a direction from the front to the rear of the housing 15.

[0027] The mounting unit 31 has a storage section 32. The storage section 32 is configured to store liquid. The storage section 32 stores liquid supplied from a liquid container 33, which will be described later. The storage section 32 is connected to a connector. The liquid is supplied from the storage section 32 to the main body section 61 through the connector.

[0028] One or more liquid containers 33 are attached to the mounting unit 31. In one example, four liquid containers 33 are attached to the mounting unit 31. The liquid containers 33 are attached to the storage portion 32. This allows liquid to be supplied from the liquid containers 33 to the storage portion 32. The liquid containers 33 are located above the storage portion 32.

[0029] The four liquid containers 33 are aligned in a third direction D3. The third direction D3 is different from the first direction D1 and the second direction D2. The third direction D3 is different from the vertical direction. In one example, the third direction D3 is a direction from the outside of the housing 15 toward the inside of the housing 15 through the maintenance port 19.

[0030] The mounting unit 31 may have a waste liquid container 34. The waste liquid container 34 contains waste liquid. The waste liquid container 34 is connected to the connector. The waste liquid container 34 is connected to the main body 61 through the connector. The waste liquid container 34 collects liquid discharged from the main body 61. The waste liquid container 34 is aligned with the storage section 32 in the third direction D3. In one example, the storage section 32 and the waste liquid container 34 are aligned in this order in the third direction D3.

[0031] As shown in Figures 6 and 7, the mounting unit 31 has a receiving tray 35. The receiving tray 35 receives liquid. In the mounting unit 31, there is a risk of liquid leaking or dripping from the storage section 32, the liquid container 33, the waste liquid container 34, and the like. The receiving tray 35 receives such liquid. The receiving tray 35 is located below the storage section 32 and the waste liquid container 34. When viewed vertically, the receiving tray 35 is located so as to overlap with the storage section 32, the liquid container 33, and the waste liquid container 34.

[0032] 8 and 9, the receiving tray 35 has a main tray 36. The main tray 36 is a portion that receives liquid from the storage section 32, the liquid container 33, the waste liquid container 34, etc. The main tray 36 is located directly below the storage section 32 and the waste liquid container 34.

[0033] The main tray 36 has a receiving wall 37 and a peripheral wall 38. The receiving wall 37 is a wall that receives liquid. The receiving wall 37 is a bottom wall of the main tray 36. The peripheral wall 38 extends from the receiving wall 37. More specifically, the peripheral wall 38 extends from the periphery of the receiving wall 37. The peripheral wall 38 is a side wall of the main tray 36.

[0034] The receiving tray 35 has a sub-tray 39. The sub-tray 39 is connected to the main tray 36. The sub-tray 39 protrudes from the main tray 36. The sub-tray 39 has a protruding wall 40. The protruding wall 40 extends from the peripheral wall 38 in one direction and in a direction different from the vertical direction. In one example, the protruding wall 40 extends from the peripheral wall 38 in a third direction D3. More specifically, the protruding wall 40 extends from the outer circumferential surface of the peripheral wall 38 in the third direction D3. The sub-tray 39 increases the area in which the receiving tray 35 can receive liquid. The sub-tray 39 receives liquid from the main body portion 61. The liquid received by the sub-tray 39 flows to the main tray 36.

[0035] The mounting unit 31 has a guide body 41. When the mounting unit 31 moves in the first direction D1, the guide body 41 is guided by a guide portion 53 described later. When the mounting unit 31 is removed, the guide body 41 is guided by the guide portion 53. The guide body 41 may also be guided by the guide portion 53 when the mounting unit 31 moves in the second direction D2, i.e., when the mounting unit 31 is mounted in the housing 15.

[0036] The guide body 41 is a protrusion. The guide body 41 protrudes from the receiving tray 35. In one example, the guide body 41 protrudes from the main tray 36. The guide body 41 protrudes from the peripheral wall 38 in the third direction D3. More specifically, the guide body 41 protrudes from the outer circumferential surface of the peripheral wall 38 in the third direction D3. The guide body 41 is aligned with the sub-tray 39 in the first direction D1. The sub-tray 39 and the guide body 41 are aligned in this order in the first direction D1.

[0037] As shown in Figs. 10 and 11, the fitting unit 31 has a protrusion 42. The protrusion 42 comes into contact with a contact portion 51, which will be described later, as the fitting unit 31 moves in the first direction D1. In detail, the protrusion 42 comes into contact with the contact portion 51 when the fitting unit 31 attached to the housing 15 is removed from the housing 15. When the protrusion 42 comes into contact with the contact portion 51, the fitting unit 31 is restricted from moving in the first direction D1. In one example, the receiving tray 35 has the protrusion 42. The protrusion 42 is located at the bottom of the receiving tray 35. The protrusion 42 is, for example, a step formed in the receiving tray 35.

[0038] The convex portion 42 has a restricting surface 43. When the restricting surface 43 comes into contact with the contact portion 51, the movement of the fitting unit 31 in the first direction D1 is restricted. The restricting surface 43 constitutes the bottom surface of the fitting unit 31. In one example, the restricting surface 43 constitutes the bottom surface of the receiving tray 35. More specifically, the restricting surface 43 constitutes the bottom surface of the main tray 36.

[0039] The protrusion 42 has a first surface 44 and a second surface 45 in addition to the regulating surface 43. The first surface 44 and the second surface 45 form the bottom surface of the receiving tray 35. More specifically, the first surface 44 and the second surface 45 form the bottom surface of the main tray 36. The first surface 44 and the second surface 45 have an extension in the first direction D1 and the third direction D3. The first surface 44, the regulating surface 43, and the second surface 45 are arranged in this order in the second direction D2. The second surface 45 is located below the first surface 44. The regulating surface 43 is connected to the first surface 44 and the second surface 45. The regulating surface 43 is inclined with respect to the first surface 44 and the second surface 45. The regulating surface 43 may be perpendicular to the first surface 44 and the second surface 45. A step is formed in the receiving tray 35 by the regulating surface 43, the first surface 44, and the second surface 45.

[0040] The fitting unit 31 is displaced between a first position P1 and a second position P2 by moving in the first direction D1 and the second direction D2. The first position P1 is a position where the fitting unit 31 is attached to the housing 15. That is, the first position P1 is a position where the fitting unit 31 is pushed into the housing 15. The second position P2 is a position where the fitting unit 31 contacts the contact portion 51. In one example, the second position P2 is a position where the convex portion 42 contacts the contact portion 51. More specifically, the second position P2 is a position where the restriction surface 43 contacts the contact portion 51. That is, the second position P2 is a position where the fitting unit 31 is restricted from moving in the first direction D1. The second position P2 is a position shifted from the first position P1 in the first direction D1. The fitting unit 31 shown in FIG. 10 is located at the first position P1. The fitting unit 31 shown in FIG. 11 is located at the second position P2.

[0041] When the mounting unit 31 is in contact with the contact portion 51, the mounting unit 31 is located at a position where the connecting body can be removed from at least one of the main body 61 and the mounting unit 31. That is, the second position P2 is a position where the connecting body can be removed. In the second position P2, the mounting unit 31 is pulled out slightly in the first direction D1. This creates a space behind the mounting unit 31. In one example, the connecting body can be removed by accessing this space through the maintenance port 19.

[0042] The attachment unit 31 may be removed from the housing 15 with the connecting body still connected. For example, the user may forget to remove the connecting body. In this case, the connecting body may be pulled and damaged. Therefore, it is preferable that the connecting body be removed from at least one of the attachment unit 31 and the main body 61 before the attachment unit 31 is removed from the housing 15. In other words, it is preferable that the connecting body be removed from the attachment unit 31, the main body 61, or both before the attachment unit 31 is removed from the housing 15.

[0043] The accommodation device 12 has a contact portion 51. The contact portion 51 comes into contact with the fitting unit 31 when the fitting unit 31 attached to the housing 15 moves in the first direction D1. In one example, the contact portion 51 comes into contact with the protrusion 42 when the fitting unit 31 moves in the first direction D1. In more detail, the contact portion 51 comes into contact with the restriction surface 43 when the fitting unit 31 moves in the first direction D1. The contact portion 51 comes into contact with the fitting unit 31 located at the second position P2.

[0044] The contact portion 51 restricts the movement of the mounting unit 31 in the first direction D1 by contacting the restricting surface 43. When the mounting unit 31 is removed from the housing 15, the contact portion 51 generates resistance by contacting the restricting surface 43. When the mounting unit 31 is removed from the first position P1, the mounting unit 31 temporarily stops at the second position P2 due to the resistance. Therefore, there is little risk that the mounting unit 31 will be removed from the housing 15 only by moving in the first direction D1. The user can attempt to remove the connection body due to the resistance to the removal of the mounting unit 31. This reduces the risk that the mounting unit 31 will be removed from the housing 15 with the connection body connected. In addition, the resistance to the removal of the mounting unit 31 reduces the risk that the mounting unit 31 will be forcefully pulled out in the first direction D1. This reduces the risk that a large tension will act on the connection body. After the connection body is removed, the mounting unit 31 will climb over the contact portion 51, and the mounting unit 31 will be removed from the housing 15.

[0045] As shown in FIG. 12, the contact portion 51 has a contact plate 52. The contact plate 52 is a plate extending in the third direction D3. The contact plate 52 is attached to the housing 15. When the fitting unit 31 is removed from the housing 15, the contact plate 52 comes into contact with the protrusion 42. When the fitting unit 31 is attached to the housing 15, the contact plate 52 may come into contact with the protrusion 42. When the fitting unit 31 is removed from the housing 15, the contact plate 52 comes into contact with the restriction surface 43. In detail, when the fitting unit 31 is removed, the contact plate 52 comes into contact with the first surface 44, the restriction surface 43, and the second surface 45 in this order. As a result, the fitting unit 31 climbs over the contact plate 52.

[0046] When the fitting unit 31 is attached to the housing 15, the convex portion 42 does not come into contact with the contact plate 52. That is, when the fitting unit 31 is located at the first position P1, the first surface 44 does not come into contact with the contact plate 52. When the fitting unit 31 moves in the first direction D1 from the first position P1, the first surface 44 comes into contact with the contact plate 52. Specifically, the contact plate 52 is located on the first surface 44. When the fitting unit 31 further moves in the first direction D1, the restricting surface 43 comes into contact with the contact plate 52. That is, the fitting unit 31 is displaced to the second position P2. When the fitting unit 31 is located at the second position P2, the movement of the fitting unit 31 in the first direction D1 is restricted. At this time, the user moves the fitting unit 31 in the first direction D1 while lifting it up. This causes the convex portion 42 to climb over the contact plate 52. As a result, the second surface 45 comes into contact with the contact plate 52. Specifically, the contact plate 52 is located on the second surface 45. When the fitting unit 31 further moves in the first direction D1, the fitting unit 31 is removed from the housing 15. In this manner, when removing the fitting unit 31, it is necessary to lift it up midway through moving it in the first direction D1.

[0047] The storage device 12 has a guide portion 53. The guide portion 53 is configured to guide the mounting unit 31. More specifically, the guide portion 53 guides the guide body 41. The guide portion 53 guides the mounting unit 31 when the mounting unit 31 is removed from the housing 15. The guide portion 53 may also guide the mounting unit 31 when the mounting unit 31 is mounted in the housing 15. In one example, the guide portion 53 guides the mounting unit 31 when the mounting unit 31 is attached to or detached from the housing 15.

[0048] The guide portion 53 extends from the contact plate 52. More specifically, the guide portion 53 extends from the tip of the contact plate 52 in the third direction D3. It can also be said that the contact portion 51 has the guide portion 53. The guide portion 53 may be configured independent of the contact portion 51. In other words, the containing device 12 may have the guide portion 53 in addition to the contact portion 51.

[0049] The guide portion 53 has a restricting portion 54 and a allowing portion 55. The restricting portion 54 is a portion that restricts the mounting unit 31 from moving upward. The allowing portion 55 is a portion that allows the mounting unit 31 to move upward. The restricting portion 54 extends, for example, upward from the contact plate 52 and then in the first direction D1. The allowing portion 55 extends, for example, upward from the restricting portion 54 and in the first direction D1. In the guide portion 53, a groove in which the guide body 41 is guided is formed by the restricting portion 54, the allowing portion 55, and the contact plate 52.

[0050] The fitting unit 31 is preferably lifted with the restricting surface 43 in contact with the contact portion 51. For example, if the fitting unit 31 is lifted with the first surface 44 in contact with the contact portion 51, the contact portion 51 may not contact the restricting surface 43. That is, the movement of the fitting unit 31 in the first direction D1 is not restricted, and the fitting unit 31 may be removed from the housing 15. The guide portion 53 guides the guide body 41 to limit the timing at which the fitting unit 31 is lifted.

[0051] As shown in FIG. 10 and FIG. 11, the guide portion 53 is configured such that the restricting portion 54 is located above the guide body 41 when the fitting unit 31 is attached to the housing 15. That is, when the fitting unit 31 is located at the first position P1, the restricting portion 54 is located above the guide body 41. The restricting portion 54 restricts the fitting unit 31 from moving upward when the fitting unit 31 is located at the first position P1. The guide portion 53 is configured such that the allowing portion 55 is located above the guide body 41 when the contact portion 51 is in contact with the restricting surface 43. That is, when the fitting unit 31 is located at the second position P2, the allowing portion 55 is located above the guide body 41. The allowing portion 55 allows the fitting unit 31 to move upward when the fitting unit 31 is located at the second position P2.

[0052] The vertical distance between the restricting portion 54 and the guide body 41 is smaller than the vertical distance between the permitting portion 55 and the guide body 41. In one example, the vertical distance between the restricting portion 54 and the contact plate 52 is smaller than the vertical distance between the permitting portion 55 and the contact plate 52. Therefore, when the fitting unit 31 located at the first position P1 moves upward, the guide body 41 is likely to come into contact with the restricting portion 54. The restricting portion 54 restricts the fitting unit 31 from moving upward by contacting with the guide body 41. Therefore, at the first position P1, lifting of the fitting unit 31 is restricted. On the other hand, even if the fitting unit 31 located at the second position P2 moves upward, the guide body 41 is unlikely to come into contact with the permitting portion 55. Therefore, at the second position P2, lifting of the fitting unit 31 is permitted.

[0053] The vertical distance between the restricting portion 54 and the guide body 41 is smaller than the distance required for the fitting unit 31 to overcome the contact portion 51. Specifically, the vertical distance between the restricting portion 54 and the guide body 41 is smaller than the vertical distance between the first surface 44 and the second surface 45. This reduces the risk that the fitting unit 31 will be removed from the housing 15 without the restricting surface 43 coming into contact with the contact portion 51. The guide portion 53 guides the fitting unit 31 located at the first position P1 in the first direction D1 by the restricting portion 54.

[0054] The vertical distance between the tolerance portion 55 and the guide body 41 is greater than the distance required for the fitting unit 31 to climb over the contact portion 51. More specifically, the vertical distance between the tolerance portion 55 and the guide body 41 is greater than the vertical distance between the first surface 44 and the second surface 45. This allows the fitting unit 31 to climb over the contact portion 51. The guide portion 53 guides the fitting unit 31 located at the second position P2 upward by the tolerance portion 55. The guide portion 53 also guides the lifted fitting unit 31 in the first direction D1 by the tolerance portion 55.

[0055] Next, the main body 61 will be described. 3, the main body 61 has a discharge unit 62. The discharge unit 62 is configured to discharge liquid onto the medium M1. The discharge unit 62 prints an image on the medium M1 by discharging the liquid onto the medium M1. The discharge unit 62 faces the support unit 25. The discharge unit 62 prints an image on the medium M1 supported by the support unit 25.

[0056] The ejection section 62 has a nozzle surface 63. One or more nozzles 64 are opened in the nozzle surface 63. The ejection section 62 ejects liquid from the nozzles 64. In one example, the ejection section 62 is positioned such that the nozzle surface 63 is oblique to the horizontal and vertical. The nozzle surface 63 faces, for example, obliquely downward.

[0057] The ejection unit 62 is elongated in one direction. For example, the ejection unit 62 is elongated in the first direction D1. This allows the ejection unit 62 to eject liquid across the width of the medium M1. In one example, the ejection unit 62 is a line head that can eject liquid simultaneously across the width of the medium M1. The ejection unit 62 may be a serial head that ejects liquid while scanning the medium M1.

[0058] The ejection portion 62 is configured to move in a direction perpendicular to the nozzle surface 63. The ejection portion 62 moves toward and away from the support portion 25 by moving in this direction.

[0059] The discharge portion 62 is connected to the connector. The liquid is supplied to the discharge portion 62 from the storage portion 32 through the connector. The connector follows the movement of the discharge portion 62. The main body 61 has a maintenance unit 65. The maintenance unit 65 maintains the discharge unit 62. More specifically, the maintenance unit 65 maintains the discharge unit 62 by flushing, capping, cleaning, and the like. Flushing is an operation in which the discharge unit 62 appropriately discharges liquid from the nozzle 64. Flushing prevents clogging of the nozzle 64. The maintenance unit 65 receives the liquid from the flushing. Capping is an operation in which the nozzle 64 is moisturized. Capping prevents clogging of the nozzle 64. The maintenance unit 65 contacts the discharge unit 62 to form a space communicating with the nozzle 64. Cleaning is an operation in which liquid is discharged from the nozzle 64. Foreign matter is discharged from the nozzle 64 together with the liquid by cleaning. The maintenance unit 65 discharges the liquid from the nozzle 64 by suction.

[0060] 4 and 5, the maintenance unit 65 has one or more caps 66. In one example, the maintenance unit 65 has a plurality of caps 66. The plurality of caps 66 are aligned in one direction. In one example, the plurality of caps 66 are aligned in the longitudinal direction of the discharge unit 62.

[0061] The cap 66 comes into contact with the ejection portion 62. In one example, the cap 66 comes into contact with the nozzle surface 63. In this way, the cap 66 caps the ejection portion 62. The cap 66 receives liquid from the ejection portion 62. The cap 66 may receive liquid ejected from the ejection portion 62 by flushing, or may receive liquid discharged from the ejection portion 62 by cleaning.

[0062] The maintenance unit 65 has a holder 67. The holder 67 holds the cap 66. The cap 66 is attached to the holder 67. The holder 67 may receive liquid that leaks or drips from the discharge unit 62, the cap 66, and the like.

[0063] The holder 67 may be configured to move in a direction perpendicular to the nozzle face 63. The holder 67 may move closer to or away from the ejection portion 62 by moving in this direction.

[0064] The holder 67 is configured to move between a contact position where the cap 66 contacts the discharge portion 62 and a retracted position where the cap 66 retracts from the discharge portion 62. The contact position is a position between the discharge portion 62 and the support portion 25. The contact position is a position where the cap 66 faces the discharge portion 62. At the contact position, the discharge portion 62 and the cap 66 approach each other, so that the cap 66 contacts the discharge portion 62. The retracted position is a position retracted from between the discharge portion 62 and the support portion 25. In one example, the retracted position is a position lower than the contact position. The holder 67 moves to the contact position when performing maintenance on the discharge portion 62. The holder 67 may move between the contact position and the retracted position by a rack and pinion or a ball screw.

[0065] The holder 67 is connected to the connecting body. The cap 66 is connected to the connecting body through the holder 67. Liquid is collected from the cap 66 to the waste liquid container 34 through the connecting body. The connecting body follows the movement of the holder 67.

[0066] The holder 67 has one or more guide plates 68. In one example, the holder 67 has two guide plates 68. The guide plates 68 guide the connecting body. This stabilizes the posture of the connecting body. Furthermore, by the guide plates 68 guiding the connecting body, the connecting body can easily follow the movement of the holder 67. The guide plates 68 are, for example, located further in the first direction D1 than the cap 66.

[0067] The main body 61 has one or more gutters. In one example, the main body 61 has a first gutter 69 and a second gutter 70. The second gutter 70 and the first gutter 69 are arranged in this order in the first direction D1, for example. The gutter is configured to drain liquid from the maintenance unit 65. Specifically, the gutter extends to drain liquid from the maintenance unit 65 to the receiving tray 35. Specifically, the gutter drains liquid from the holder 67 to the receiving tray 35. The gutter drains liquid received by the holder 67 to the receiving tray 35. The gutter is attached to the housing 15. The gutter is positioned to receive liquid dripping from the holder 67, for example. The gutter is positioned to drain liquid into the receiving tray 35.

[0068] The gutter has a base end and a tip end. The first gutter 69 has a first base end 71 and a first tip end 72. The second gutter 70 has a second base end 73 and a second tip end 74. The gutter extends so that liquid flows from the base end to the tip end. When viewed vertically, the base end overlaps with the holder 67. Specifically, when viewed vertically, the base end overlaps with at least the holder 67 located at the contact position. When the holder 67 is located at the retracted position, the gutter may receive liquid from the holder 67 at a portion between the base end and the tip end. When viewed vertically, the tip end overlaps with the receiving tray 35. Specifically, when the mounting unit 31 located at the first position P1 is viewed vertically, the tip end overlaps with the receiving tray 35. When the mounting unit 31 located at the second position P2 is viewed vertically, the tip end does not overlap with the receiving tray 35.

[0069] 8, when the fitting unit 31 is located at the first position P1 and viewed vertically, the first tip 72 overlaps with the protruding wall 40. Therefore, the first gutter 69 allows liquid to flow into the sub-tray 39. When the fitting unit 31 is located at the first position P1 and viewed vertically, the second tip 74 overlaps with the receiving wall 37. Therefore, the second gutter 70 allows liquid to flow into the main tray 36.

[0070] As shown in FIG. 9, when the fitting unit 31 located at the second position P2 is viewed from the vertical direction, the first tip 72 does not overlap with the protruding wall 40. That is, at the second position P2, the first tip 72 does not overlap with the receiving tray 35. More specifically, when the fitting unit 31 located at the second position P2 is viewed from the vertical direction, the first tip 72 is positioned so as to be adjacent to the protruding wall 40. When the fitting unit 31 located at the second position P2 is viewed from the vertical direction, the second tip 74 does not overlap with the receiving wall 37. More specifically, when the fitting unit 31 located at the second position P2 is viewed from the vertical direction, the second tip 74 is positioned so as to be adjacent to the peripheral wall 38. This reduces the risk that the fitting unit 31 lifted at the second position P2 will interfere with the gutter. That is, the risk that the gutter will hinder the removal of the fitting unit 31 is reduced. If the first gutter 69 extends to allow liquid to flow into the main tray 36, the first tip 72 is less likely to retract from the receiving tray 35 even if the fitting unit 31 is displaced from the first position P1 to the second position P2. In this regard, by allowing the first gutter 69 to extend to allow liquid to flow into the sub-tray 39, the first tip 72 is more likely to retract from the receiving tray 35 when the fitting unit 31 is displaced from the first position P1 to the second position P2.

[0071] Next, the connector will be described. As shown in FIG. 3, the storage device 12 has a connector. The connector is connected to the main body 61 and the mounting unit 31. The connector can follow the movement of the mounting unit 31 or the movement of the main body 61 due to its flexibility. In one example, the storage device 12 has a first connector 81 and a second connector 82. The first connector 81 is connected to the storage section 32 and the discharge section 62. The second connector 82 is connected to the waste liquid storage body 34 and the maintenance section 65. The first connector 81 and the second connector 82 form a flow path through which the liquid flows. The connector has, for example, a tube, a joint, or the like. The tube is flexible.

[0072] 4 and 5, the first connector 81 has a supply tube 83. The supply tube 83 is connected to the storage portion 32. The supply tube 83 is connected to the storage portion 32 behind the liquid container 33. The supply tube 83 extends from the rear of the liquid container 33. The supply tube 83 extends from the storage portion 32 to the discharge portion 62 while curving in an arc. This is because the supply tube 83 follows the movement of the discharge portion 62.

[0073] The first connector 81 has a supply joint 84. The supply joint 84 is connected to the discharge portion 62. The supply joint 84 is attached to, for example, the housing 15. The supply joint 84 is connected to a supply tube 83. Liquid is supplied from the storage portion 32 to the discharge portion 62 through the supply tube 83 and the supply joint 84.

[0074] The first connector 81 is removed from at least one of the attachment unit 31 and the main body 61 through the maintenance port 19. The supply tube 83 may be removed from the storage portion 32, and the supply fitting 84 may be removed from the discharge portion 62. The first connector 81 is removed through the maintenance port 19, for example. The first connector 81 may be removed through the attachment port 18.

[0075] 6 and 7, the second connector 82 has a flow path member 85. The flow path member 85 is a member formed by, for example, welding a resin film, a resin cover, or the like to a resin base material having grooves engraved thereon. The flow path member 85 is located behind the mounting unit 31. The flow path member 85 is attached to the housing 15. The flow path member 85 is connected to the waste liquid container 34, for example, through a tube (not shown).

[0076] The second connector 82 has one or more waste liquid tubes and one or more waste liquid joints. The second connector 82 has, for example, two first waste liquid tubes 86, one first waste liquid joint 87, two second waste liquid tubes 88, one second waste liquid joint 89, two third waste liquid tubes 90, and one third waste liquid joint 91. The second connector 82 has two each of the first waste liquid tubes 86, the second waste liquid tubes 88, and the third waste liquid tubes 90, so that the flow path area of ​​the second connector 82 is increased. This makes it easier for liquid to flow through the second connector 82.

[0077] As shown in Figures 13 and 14, the first waste liquid tube 86 is connected to the flow path member 85 and the first waste liquid joint 87. The second waste liquid tube 88 is connected to the first waste liquid joint 87 and the second waste liquid joint 89. The third waste liquid tube 90 is connected to the second waste liquid joint 89 and the third waste liquid joint 91. The third waste liquid tube 90 is guided by the guide plate 68. The first waste liquid joint 87, the second waste liquid joint 89 and the third waste liquid joint 91 are attached to the holder 67. The third waste liquid joint 91 is connected to the holder 67 so as to be able to recover liquid from the cap 66.

[0078] The two first waste liquid tubes 86 extend from the flow path member 85 to the first waste liquid joint 87 while curving in an arc. This is because the two first waste liquid tubes 86 follow the movement of the holder 67. When the holder 67 is located at the retracted position, the curvature of the first waste liquid tube 86 is larger than when the holder 67 is located at the contact position. The two curved first waste liquid tubes 86 extend while being pulled together. Therefore, of the two first waste liquid tubes 86, the first waste liquid tube 86 located on the inside and the first waste liquid tube 86 located on the outside have different curvatures. Of the two first waste liquid tubes 86, the first waste liquid tube 86 located on the inside is shorter than the first waste liquid tube 86 located on the outside. This makes it easier for the two first waste liquid tubes 86 to fit into a specified space.

[0079] The second connector 82 is removed from at least one of the mounting unit 31 and the main body 61 through the maintenance port 19. The flow path member 85 may be removed from the waste liquid container 34, and the third waste liquid joint 91 may be removed from the holder 67. The second connector 82 is removed through the maintenance port 19, for example. The second connector 82 may be removed through the mounting port 18.

[0080] As shown in FIG. 15, the second connector 82 may have a band member 92. The band member 92 is a member that connects the waste liquid joints to each other. In one example, the band member 92 is attached to the second waste liquid joint 89 and the third waste liquid joint 91. When removing the third waste liquid joint 91 from the holder 67, the user may pull the third waste liquid joint 91 out of the holder 67 with force. In this case, the third waste liquid joint 91 may be lifted with force, causing the third waste liquid tube 90 to come off from the third waste liquid joint 91, or the second waste liquid joint 89 to come off from the third waste liquid tube 90. In this regard, the band member 92 protects the connection between the third waste liquid joint 91 and the third waste liquid tube 90, and the connection between the third waste liquid tube 90 and the second waste liquid joint 89. Therefore, the risk of the third drainage tube 90 becoming detached from the third drainage joint 91 or the second drainage joint 89 becoming detached from the third drainage tube 90 is reduced.

[0081] <Action and Effects> Next, the operation and effects of the above embodiment will be described. (1) The contact portion 51 comes into contact with the fitting unit 31 as the fitting unit 31 attached to the housing 15 moves in the first direction D1. According to the above configuration, the fitting unit 31 comes into contact with the contact portion 51, thereby restricting the movement of the fitting unit 31 in the first direction D1. This reduces the risk that the fitting unit 31 will be removed from the housing 15 simply by moving in the first direction D1. This reduces the risk that the fitting unit 31 will be removed from the housing 15 with the connecting body connected to the main body 61 and the fitting unit 31. This reduces the risk that the connecting body will be damaged.

[0082] (2) The fitting unit 31 has the protrusion 42 that moves in the first direction D1 to come into contact with the contact portion 51. The protrusion 42 is located at the bottom of the fitting unit 31. With the above-described configuration, it is possible to restrict the movement of the fitting unit 31 in the first direction D1 with a simple configuration.

[0083] (3) When the mounting unit 31 is in contact with the contact portion 51, the mounting unit 31 is located at a position where the connecting body can be removed from at least one of the main body 61 and the mounting unit 31. According to the above configuration, the connecting body can be easily removed in the process of removing the mounting unit 31.

[0084] (4) The guide portion 53 has a restricting portion 54 and a permitting portion 55. When the fitting unit 31 is located at the second position P2, the vertical distance between the guide body 41 and the permitting portion 55 is greater than the vertical distance required for the fitting unit 31 to overcome the contact portion 51. According to the above configuration, the guide portion 53 guides the fitting unit 31 so that it cannot move upward at the first position P1, and guides the fitting unit 31 so that it can move upward at the second position P2. The fitting unit 31 overcomes the contact portion 51 by moving upward. As a result, the fitting unit 31 is removed from the housing 15. In this manner, the guide portion 53 guides the fitting unit 31, so that the fitting unit 31 is smoothly removed.

[0085] (5) When viewed vertically, the tip of the gutter overlaps with the receiving tray 35. According to the above configuration, liquid flows through the gutter from the maintenance part 65 to the receiving tray 35. By removing the mounting unit 31, the liquid received by the receiving tray 35 can be collected.

[0086] (6) When the fitting unit 31 located at the first position P1 is viewed vertically, the first tip 72 overlaps with the protruding wall 40. When the fitting unit 31 located at the first position P1 is viewed vertically, the second tip 74 overlaps with the receiving wall 37. According to the above configuration, when the fitting unit 31 is displaced from the first position P1 to the second position P2, the first gutter 69 and the second gutter 70 are easily retracted from the receiving tray 35. Therefore, when the fitting unit 31 is removed, the first gutter 69 and the second gutter 70 are less likely to come into contact with the receiving tray 35.

[0087] <Example of change> The above embodiment can be modified as follows: The above embodiment and the following modified examples can be combined with each other to the extent that there is no technical contradiction.

[0088] The storage device 12 is not limited to the liquid ejection device 11 and may be applied to other devices having a mounting unit 31 and a main body portion 61 . The connector is not limited to a tube, but may include wiring such as a flexible flat cable or a signal line.

[0089] The liquid ejected by the ejection unit 62 is not limited to ink, and may be, for example, a liquid in which particles of a functional material are dispersed or mixed in a liquid. For example, the ejection unit 62 may eject a liquid containing, in a dispersed or dissolved form, a material such as an electrode material or a pixel material used in the manufacture of liquid crystal displays, electroluminescence displays, and surface-emitting displays.

[0090] <Technical philosophy> The technical ideas and effects obtained from the above-mentioned embodiment and modified examples will be described below.

[0091] (A) The storage device includes a housing with an opening for mounting, a main body located in the housing, a mounting unit mounted on the housing, a connecting body connected to the main body and the mounting unit, and a contact part that contacts the mounting unit, and the mounting unit is configured to move in one direction from inside the housing to outside the housing through the mounting opening, and the contact part contacts the mounting unit when the mounting unit mounted on the housing moves in the one direction. According to the above configuration, the mounting unit is restricted from moving in the one direction by contacting the contact part. Therefore, the risk of the mounting unit being removed from the housing by moving only in the one direction is reduced. This reduces the risk of the mounting unit being removed from the housing with the connecting body connected to the main body and the mounting unit. Therefore, the risk of the connecting body being damaged is reduced.

[0092] (B) In the above-mentioned storage device, the fitting unit may have a protrusion that contacts the contact portion by moving in the one direction, and the protrusion may be located on a bottom of the fitting unit. With the above-mentioned configuration, it is possible to restrict the fitting unit from moving in the one direction with a simple configuration.

[0093] (C) In the above-described storage device, the attachment unit may be located at a position where the connection body can be removed from at least one of the main body and the attachment unit when in contact with the contact portion. According to the above-described configuration, the connection body can be easily removed in the process of removing the attachment unit.

[0094] (D) The storage device includes a guide portion that guides the mounting unit when the mounting unit moves in the one direction, and the mounting unit has a guide body that is guided by the guide portion, and the guide portion has a restricting portion that restricts the mounting unit from moving upward when the mounting unit is located at a first position, and a permitting portion that permits the mounting unit to move upward when the mounting unit is located at a second position, the first position being a position where the mounting unit is mounted on the housing, the second position being a position where the mounting unit contacts the contact portion, and the vertical distance between the guide body and the permitting portion when the mounting unit is located at the second position may be greater than the vertical distance required for the mounting unit to overcome the contact portion. According to the above configuration, the guide portion guides the mounting unit so that it cannot move upward in the first position, and guides the mounting unit so that it can move upward in the second position. The mounting unit overcomes the contact portion by moving upward. This allows the mounting unit to be removed from the housing. In this manner, the guide portion guides the fitting unit, so that the fitting unit can be smoothly removed.

[0095] (E) In the above-mentioned storage device, the contact portion has a guide portion that guides the mounting unit when the mounting unit moves in the one direction, and the mounting unit has a guide body that is guided by the guide portion, and the guide portion has a restricting portion that restricts the mounting unit from moving upward when the mounting unit is located at a first position, and a permitting portion that permits the mounting unit to move upward when the mounting unit is located at a second position, the first position being a position where the mounting unit is mounted on the housing, the second position being a position where the mounting unit contacts the contact portion, and the vertical distance between the guide body and the permitting portion when the mounting unit is located at the second position may be greater than the vertical distance required for the mounting unit to get over the contact portion. According to the above-mentioned configuration, the guide portion guides the mounting unit so that it cannot move upward in the first position, and guides the mounting unit so that it can move upward in the second position. The mounting unit gets over the contact portion by moving upward. This allows the mounting unit to be removed from the housing. In this manner, the guide portion guides the fitting unit, so that the fitting unit can be smoothly removed.

[0096] (F) A liquid ejection device includes the above-mentioned storage device, the main body having a nozzle surface where a nozzle opens, an ejection section that ejects liquid from the nozzle, a maintenance section that maintains the ejection section, and a gutter through which liquid flows from the maintenance section, the mounting unit having a receiving tray that receives liquid, and a tip of the gutter overlaps with the receiving tray when viewed vertically. According to the above configuration, liquid flows from the maintenance section to the receiving tray through the gutter. The liquid received by the receiving tray can be collected by removing the mounting unit.

[0097] (G) A liquid ejection device includes the above-mentioned storage device, the main body having a nozzle surface where a nozzle opens, an ejection section that ejects liquid from the nozzle, a maintenance section that maintains the ejection section, and a gutter through which liquid flows from the maintenance section, the mounting unit having a receiving tray that receives liquid, and a tip of the gutter overlaps with the receiving tray when viewed vertically. According to the above configuration, liquid flows from the maintenance section to the receiving tray through the gutter. The liquid received by the receiving tray can be collected by removing the mounting unit.

[0098] (H) In the liquid ejection device, the gutter is a first gutter, the main body has a second gutter, the second gutter and the first gutter are arranged in this order in the one direction, the receiving tray has a receiving wall that receives liquid, a peripheral wall extending from the periphery of the receiving wall, and a protruding wall extending from the peripheral wall in a direction different from the one direction and the vertical direction, and when the fitting unit located at the first position is viewed from the vertical direction, the tip of the first gutter overlaps with the protruding wall, and when the fitting unit located at the first position is viewed from the vertical direction, the tip of the second gutter overlaps with the receiving wall. According to the above configuration, when the fitting unit is displaced from the first position to the second position, the first gutter and the second gutter are easily retracted from the receiving tray. Therefore, when the fitting unit is removed, the risk of the first gutter and the second gutter coming into contact with the receiving tray is reduced.

[0099] (I) In the above liquid ejection device, the gutter is a first gutter, the main body has a second gutter, the second gutter and the first gutter are arranged in this order in the one direction, the receiving tray has a receiving wall for receiving liquid, a peripheral wall extending from the periphery of the receiving wall, and a protruding wall extending from the peripheral wall in a direction different from the one direction and the vertical direction, and when the fitting unit located at the first position is viewed from the vertical direction, the tip of the first gutter overlaps with the protruding wall, and when the fitting unit located at the first position is viewed from the vertical direction, the tip of the second gutter overlaps with the receiving wall. According to the above configuration, when the fitting unit is displaced from the first position to the second position, the first gutter and the second gutter are easily retracted from the receiving tray. Therefore, when the fitting unit is removed, the risk of the first gutter and the second gutter coming into contact with the receiving tray is reduced. [Explanation of symbols]
