Detailed implementation mode

[0024] Hereinafter, an embodiment of a liquid ejection system including a liquid ejection device will be described with reference to the accompanying Figure 1 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 cloth.

[0025] As Figure 1 shown, the liquid ejection system 11 includes a liquid ejection device 12 and an assembly unit 13. The liquid ejection device 12 is configured to eject liquid. The assembly unit 13 is configured to be connectable to the liquid ejection device 12. In Figure 1 this case, the assembly unit 13 is connected to the liquid ejection device 12. The assembly unit 13 is configured to assemble a later-described liquid container 63. By connecting the assembly unit 13 to the liquid ejection device 12, liquid can be supplied from the assembly unit 13 to the liquid ejection device 12.

[0026] Liquid ejection device

[0027] First, the liquid ejection device 12 will be described.

[0028] The liquid ejection device 12 includes a device housing 14. The device housing 14 is, for example, elongated in one direction. In one example, the device housing 14 is elongated in the scanning direction D1. The device housing 14 has a first housing portion 15, a second housing portion 16, and a central housing portion 17. The first housing portion 15 and the second housing portion 16 are portions located at the ends of the device housing 14 in the scanning direction D1. The central housing portion 17 is a portion adjacent to the first housing portion 15 and the second housing portion 16. The central housing portion 17 is sandwiched between the first housing portion 15 and the second housing portion 16 in the scanning direction D1. The first housing portion 15, the central housing portion 17, and the second housing portion 16 are arranged in this order in the scanning direction D1.

[0029] The liquid ejection device 12 includes legs 18. The legs 18 support the device housing 14. In one example, the legs 18 extend downward from the first housing portion 15 and the second housing portion 16. The legs 18 have a first leg portion 19 and a second leg portion 20. The first leg portion 19 is a portion that extends downward from the first housing portion 15. The second leg portion 20 is a portion that extends downward from the second housing portion 16.

[0030] The liquid ejection device 12 may also be configured to house the assembly unit 13 in its bottom space. For example, the liquid ejection device 12 may define a placement space A1. In one example, the device housing 14 and the legs 18 define the placement space A1. The placement space A1 is an area for housing the assembly unit 13 connected to the liquid ejection device 12. The placement space A1 is an area that overlaps the device housing 14 when viewed from the vertical direction D2. In one example, the placement space A1 is an area vertically below the first housing portion 15. Therefore, when viewed from the vertical direction D2, the device housing 14 overlaps the assembly unit 13. Specifically, when viewed from the vertical direction D2, the first housing portion 15 overlaps the assembly unit 13. By having the assembly unit 13 located in the placement space A1, the possibility of the bottom space of the liquid ejection system 11 increasing is reduced.

[0031] As Figure 2 shown, the liquid ejection device 12 includes an ejection unit 21. The ejection unit 21 is configured to eject liquid. The ejection unit 21 ejects liquid onto a medium M1. For example, the ejection unit 21 ejects liquid onto the medium M1 conveyed within the device housing 14. In the liquid ejection device 12, the medium M1 is conveyed in the conveying direction D3. The conveying direction D3 is a direction different from the vertical direction D2. In one example, the conveying direction D3 is also a direction different from the scanning direction D1. For example, the conveying direction D3 is a direction from the rear of the device housing 14 toward the front. The medium M1 is discharged from the front surface of the device housing 14 after printing. The ejection unit 21 prints an image on the medium M1 by ejecting liquid onto the medium M1.

[0032] The ejection unit 21 is configured to scan the medium M1. The ejection unit 21 is configured to move in the scanning direction D1. Specifically, the ejection unit 21 moves in the scanning direction D1 and its opposite direction within the device housing 14. Thereby, the ejection unit 21 can eject liquid over the entire width of the medium M1. Thus, in one example, the ejection unit 21 is a serial head. The ejection unit 21 may also be a line head capable of simultaneously ejecting liquid over the entire width of the medium M1.

[0033] The liquid ejection device 12 includes a device flow path 22. The device flow path 22 is configured to allow liquid to flow. The device flow path 22 extends from the ejection unit 21. The device flow path 22 is connected to the ejection unit 21 and the assembly unit 13. Liquid is supplied from the assembly unit 13 to the ejection unit 21 through the device flow path 22.

[0034] The device flow path 22 has one or more flow portions 23. The flow portion 23 is a portion through which liquid flows. The flow portion 23 is connected to the ejection unit 21. The flow portion 23 extends within the device housing 14. The flow portion 23 includes, for example, a tube. The device flow path 22 has the same number of flow portions 23 as the liquid storage body 63. Thereby, the device flow path 22 can supply liquid from a plurality of liquid storage bodies 63 to the ejection unit 21.

[0035] The device flow path 22 has a connection portion 24. The connection portion 24 is configured to be connected to the assembly unit 13. In one example, the connection portion 24 is configured to be connected to the assembly unit 13 located vertically below. For example, since the assembly unit 13 is located directly below the connection portion 24, the connection portion 24 can be connected to the assembly unit 13.

[0036] The connection portion 24 forms the upstream end of the device flow path 22. Specifically, the connection portion 24 forms the upstream end of the device flow path 22 in the direction of liquid flow. The connection portion 24 is connected to the flow portion 23. The connection portion 24 is, for example, a joint.

[0037] As Figure 3 shown, the connection portion 24 is located at a position exposed from the device housing 14. In one example, the connection portion 24 is exposed in a manner that can be visually confirmed from below the device housing 14. Specifically, the connection portion 24 is exposed in a manner that can be visually confirmed from below the first housing portion 15. The connection portion 24 is fixed to the device housing 14.

[0038] The connection portion 24 has a connection body 25. The connection body 25 holds the flow portion 23. The connection body 25 is, for example, a resin housing. The connection body 25 extends in the vertical direction D2. The connection body 25 has a connection surface 26. The connection surface 26 is a surface facing the assembly unit 13. In one example, the connection surface 26 faces downward.

[0039] The connector 25 has one or more pressure-receiving portions 27. In one example, the connector 25 has two pressure-receiving portions 27. The pressure-receiving portion 27 is a portion that receives pressure from the assembly unit 13 when the connecting portion 24 is detached from the assembly unit 13. The pressure-receiving portion 27 protrudes from the connection surface 26. The pressure-receiving portion 27 protrudes in a manner close to the assembly unit 13. For example, the pressure-receiving portion 27 protrudes downward from the connection surface 26.

[0040] One or more guide holes 28 may be formed in the connector 25. In one example, two guide holes 28 are formed in the connector 25. The guide holes 28 are formed in the connection surface 26. The guide holes 28 penetrate the connector 25. For example, the guide holes 28 penetrate the connector 25 in the vertical direction D2. The assembly unit 13 is inserted into the guide holes 28. Thereby, the assembly unit 13 is guided to the liquid ejection device 12. By inserting the assembly unit 13 into the guide holes 28, the position of the assembly unit 13 relative to the connecting portion 24 is adjusted. Therefore, the connecting portion 24 can be easily connected to the assembly unit 13.

[0041] The connector 25 may also have one or more insertion portions 29. In one example, the connector 25 has two insertion portions 29. The insertion portion 29 is a portion into which the assembly unit 13 is inserted. A portion of the assembly unit 13 different from the portion inserted into the guide holes 28 is inserted into the insertion portion 29. The insertion portion 29 protrudes from the connection surface 26. The insertion portion 29 protrudes in a manner close to the assembly unit 13 from the connection surface 26. For example, the insertion portion 29 protrudes downward from the connection surface 26.

[0042] An insertion opening 30 is formed in the insertion portion 29. The insertion opening 30 is formed in a direction different from that of the guide holes 28. The insertion opening 30 is formed in the insertion portion 29 in a direction parallel to the connection surface 26. In one example, the insertion opening 30 is formed in the conveying direction D3. The insertion opening 30 penetrates the insertion portion 29 in the conveying direction D3. By inserting the assembly unit 13 into the insertion opening 30, the possibility of the connecting portion 24 being detached from the assembly unit 13 is reduced.

[0043] The connecting portion 24 has one or more connecting pipes 31. The connecting portion 24 has the same number of connecting pipes 31 as the flow portion 23. In one example, the connecting portion 24 has six connecting pipes 31. The connecting pipes 31 are mounted on the connector 25. The connecting pipes 31 are located at positions protruding from the connection surface 26. In one example, the connecting pipes 31 face downward. The six connecting pipes 31 are located at positions avoiding the pressure-receiving portions 27.

[0044] The connecting pipe 31 is connected to the flow part 23. The connecting part 24 is connected to the fitting unit 13 by inserting the connecting pipe 31 into the fitting unit 13 or inserting the fitting unit 13 into the connecting pipe 31. In one example, the connecting pipe 31 is connected to the fitting unit 13 by being inserted into the fitting unit 13. When the connecting pipe 31 is connected to the fitting unit 13, the liquid flows through the connecting pipe 31 to the flow part 23.

[0045] As Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the connecting part 24 can also be configured to move between a connection position P1 and a separation position P2. In one example, the connecting part 24 moves between the connection position P1 and the separation position P2 by moving in the vertical direction D2 and the opposite direction thereof.

[0046] The connection position P1 is the position where the connecting part 24 is connected to the fitting unit 13. The connection position P1 is a position close to the fitting unit 13. Figure 4 and Figure 6 shown, the connecting part 24 is located at the connection position P1. The connecting part 24 is displaced from the separation position P2 to the connection position P1 by moving in the vertical direction D2.

[0047] The separation position P2 is the position where the connecting part 24 is separated from the fitting unit 13. The separation position P2 is the position where the connecting part 24 is separated from the fitting unit 13. At the separation position P2, the connecting part 24 is not connected to the fitting unit 13. Figure 5 and Figure 7 shown, the connecting part 24 is located at the separation position P2. The separation position P2 is a position higher than the connection position P1. The connecting part 24 is displaced from the connection position P1 to the separation position P2 by moving in the direction opposite to the vertical direction D2.

[0048] The connecting part 24 may also have a contact member 32. The contact member 32 is a member that contacts a holding part 36 described later. Specifically, the contact member 32 contacts the holding part 36 when the connecting part 24 is located at the separation position P2. The contact member 32 is mounted on the connecting body 25. In one example, the contact member 32 is configured to extend from the rear surface of the connecting body 25.

[0049] The contact member 32 has an extension part 33. The extension part 33 is a part that extends along the connecting body 25. After the extension part 33 extends rearward from the rear surface of the connecting body 25, it extends upward along the rear surface of the connecting body 25. The base end of the extension part 33 is mounted on the connecting body 25.

[0050] The contact member 32 has an operation portion 34. The operation portion 34 is configured to be grippable. The operation portion 34 is gripped by a user, for example. The operation portion 34 extends from the extension portion 33. Specifically, the operation portion 34 extends rearward from the front end of the extension portion 33. While gripping the operation portion 34, the user moves the connecting portion 24 between the connection position P1 and the separation position P2.

[0051] The contact member 32 has a protrusion 35. The protrusion 35 is a portion that is hooked to the holding portion 36. The protrusion 35 protrudes from the extension portion 33. Specifically, the protrusion 35 protrudes forward from the front end of the extension portion 33. The protrusion 35 is located between the extension portion 33 and the connector 25.

[0052] The liquid ejection device 12 may also include a holding portion 36. The holding portion 36 is configured to hold the connecting portion 24. Specifically, the holding portion 36 holds the connecting portion 24 located at the separation position P2. By holding the connecting portion 24 with the holding portion 36, the possibility that the connecting portion 24 accidentally displaces from the separation position P2 to the connection position P1 is reduced. For example, if the assembly unit 13 is arranged in the arrangement space A1 in a state where the connecting portion 24 is located at the connection position P1, there is a possibility that the connecting portion 24 collides with the assembly unit 13.

[0053] The holding portion 36 has a base member 37. The base member 37 is configured to surround the connecting portion 24. The base member 37 surrounds the connector 25. In one example, the base member 37 surrounds the connector 25 regardless of the position of the connector 25. Specifically, when the connecting portion 24 is located at the connection position P1, the base member 37 surrounds the upper portion of the connector 25. When the connecting portion 24 is located at the separation position P2, the base member 37 surrounds the lower portion of the connector 25. The connecting portion 24 is displaced in a state where the connector 25 is surrounded by the base member 37.

[0054] The base member 37 has a guide surface 38. The guide surface 38 is a surface that faces the contact member 32. Specifically, the guide surface 38 faces the extension portion 33 when the connecting portion 24 is located at the separation position P2. In one example, the guide surface 38 faces rearward.

[0055] The holding portion 36 has a holding member 39. The holding member 39 is a member that contacts the contact member 32. The holding member 39 extends from the base member 37. The holding member 39 extends from the upper end of the base member 37. The holding member 39 extends rearward from the guide surface 38. The holding member 39 contacts the protrusion 35. Specifically, the protrusion 35 is hooked to the holding member 39. Thereby, the holding member 39 holds the contact member 32. As a result, the holding portion 36 holds the connecting portion 24.

[0056] The holding portion 36 has one or more guide members 40. In one example, the holding portion 36 has two guide members 40. The guide member 40 is a member that guides the contact member 32. Specifically, the guide member 40 guides the extension portion 33. The guide member 40 extends from the base member 37. The guide member 40 extends rearward from the guide surface 38. The two guide members 40 are located at positions sandwiching the contact member 32 in the scanning direction D1.

[0057] The guide member 40 has a first guide piece 41 and a second guide piece 42. The first guide piece 41 extends vertically from the guide surface 38. The two first guide pieces 41 are located at positions sandwiching the extension portion 33 in the scanning direction D1. The second guide piece 42 extends from the first guide piece 41. The second guide piece 42 extends vertically from the front end of the first guide piece 41 and is perpendicular to the first guide piece 41. The two second guide pieces 42 extend in a manner approaching each other.

[0058] When the connecting portion 24 is displaced from the connection position P1 to the separation position P2, the extension portion 33 is inserted between the base member 37 and the second guide piece 42. At this time, the guide member 40 guides the contact member 32. When the connecting portion 24 is located at the separation position P2, the protrusion 35 is hooked on the holding member 39. Thus, the holding portion 36 holds the connecting portion 24 at the separation position P2. When the protrusion 35 is detached from the holding member 39 by pulling the operation portion 34, the connecting portion 24 can be displaced from the separation position P2 to the connection position P1.

[0059] The liquid ejecting device 12 includes a receiving portion 43. The receiving portion 43 is configured to receive liquid. The receiving portion 43 receives the liquid dripping from the connecting portion 24. When the connecting portion 24 is detached from the assembling unit 13, there is a possibility that liquid drips from the connecting portion 24. Specifically, there is a possibility that liquid drips from the connecting tube 31. In particular, since the connecting tube 31 faces downward, it is easy for the liquid to drip from the connecting tube 31. By receiving the liquid dripping from the connecting tube 31 with the receiving portion 43, the possibility of the surroundings of the liquid ejecting device 12 being soiled is reduced.

[0060] The receiving portion 43 is located vertically below the connecting portion 24. That is, the receiving portion 43 is located directly below the connecting portion 24. Thus, the receiving portion 43 receives the liquid from the connecting portion 24. Since the receiving portion 43 is located vertically below the connecting portion 24, it sometimes hinders the connection between the connecting portion 24 and the assembling unit 13. This is because the connecting tube 31 faces downward. For example, when the connecting tube 31 faces rearward, even if the receiving portion 43 is located below the connecting portion 24, the connecting portion 24 can be connected to the assembling unit 13 without being hindered by the receiving portion 43.

[0061] The receiving unit 43 is configured to move between a receiving position Q1 and a retracted position Q2. In one example, the receiving unit 43 moves between the receiving position Q1 and the retracted position Q2 by moving in the conveying direction D3 and the opposite direction thereof. The receiving unit 43 can be displaced either by moving in the scanning direction D1 or by rotating.

[0062] The receiving position Q1 is the position where the receiving unit 43 receives the liquid from the connecting portion 24. The receiving position Q1 is a position vertically below the connecting portion 24. The receiving position Q1 is a position directly below the connecting portion 24. The receiving position Q1 is a position that overlaps the connecting portion 24 when viewed from the vertical direction D2. Figure 5 and Figure 7 The receiving unit 43 shown is located at the receiving position Q1. When located at the receiving position Q1, the receiving unit 43 is located on the movement trajectory of the connecting portion 24 that moves between the connection position P1 and the separation position P2. Therefore, if the connecting portion 24 is displaced from the separation position P2 to the connection position P1 while in the state of being located at the receiving position Q1, the receiving unit 43 interferes with the connecting portion 24.

[0063] The retracted position Q2 is the position where the receiving unit 43 retracts from the connecting portion 24. The retracted position Q2 is a position retracted from vertically below the connecting portion 24. The retracted position Q2 is a position where the receiving unit 43 does not receive the liquid from the connecting portion 24. The retracted position Q2 is a position where the receiving unit 43 does not overlap the connecting portion 24 when viewed from the vertical direction D2. Figure 4 and Figure 6 The receiving unit 43 shown is located at the retracted position Q2. When located at the retracted position Q2, the receiving unit 43 is located outside the movement trajectory of the connecting portion 24 that moves between the connection position P1 and the separation position P2. Therefore, when located at the retracted position Q2, the receiving unit 43 does not interfere with the connecting portion 24. When located at the retracted position Q2, the receiving unit 43 does not hinder the connection between the connecting portion 24 and the assembling unit 13.

[0064] The receiving unit 43 has a receiving part 44. The receiving part 44 is, for example, a tray. The receiving part 44 is vertically directly below the connecting portion 24 at the receiving position Q1. The receiving part 44 has a receiving surface 45. The receiving surface 45 is the surface that receives the liquid from the connecting portion 24. The receiving surface 45 faces the connecting portion 24 at the receiving position Q1. In one example, the receiving surface 45 faces the connecting surface 26 at the receiving position Q1. The receiving unit 43 may also have an absorbent material. The absorbent material may also be arranged on the receiving surface 45.

[0065] The receiving portion 44 has more than one convex portion 46. In one example, the receiving portion 44 has four convex portions 46. The convex portions 46 protrude from the side surface of the receiving portion 44. Among the four convex portions 46, two convex portions 46 protrude from the receiving portion 44 in the scanning direction D1. Among the four convex portions 46, the other two convex portions 46 protrude from the receiving portion 44 in the direction opposite to the scanning direction D1. The four convex portions 46 are symmetrically located in the scanning direction D1, for example.

[0066] The convex portion 46 is inserted into the housing portion 48 described later. By inserting the convex portion 46 into the housing portion 48, the receiving portion 44 is held at the receiving position Q1, or the receiving portion 44 is held at the retracted position Q2.

[0067] The receiving portion 43 has a gripping portion 47. The gripping portion 47 is configured to be grippable. The gripping portion 47 is gripped by a user, for example. The gripping portion 47 extends from the receiving portion 44. Specifically, the gripping portion 47 extends rearward from the front end of the receiving portion 44. The user moves the receiving portion 43 between the receiving position Q1 and the retracted position Q2 while gripping the gripping portion 47.

[0068] The liquid ejection device 12 includes a housing portion 48. The housing portion 48 is configured to house the receiving portion 43. The housing portion 48 is configured to be able to insert and remove the receiving portion 43, for example. The housing portion 48 is located at a position that does not overlap with the connecting portion 24 when viewed from the vertical direction D2. The receiving portion 43 is displaced to the receiving position Q1 by being pulled out from the housing portion 48. The receiving position Q1 is the position where the receiving portion 43 protrudes from the housing portion 48. The receiving portion 43 is displaced to the retracted position Q2 by being pushed into the housing portion 48. The retracted position Q2 is the position where the receiving portion 43 is housed in the housing portion 48.

[0069] The housing portion 48 has a housing frame 49. The housing frame 49 is a frame that houses the receiving portion 43 located at the retracted position Q2. Specifically, the housing frame 49 houses the receiving portion 44. In a state where the receiving portion 44 is housed in the housing frame 49, the gripping portion 47 protrudes from the housing frame 49. Therefore, it is easy for the user to grip the gripping portion 47.

[0070] The liquid ejection device 12 may also include a guide frame 50. The guide frame 50 is a frame that guides the receiving portion 43. Specifically, the guide frame 50 guides the receiving portion 43 protruding from the housing portion 48. A guide slit 51 is formed in the guide frame 50. The edge of the receiving portion 44 is inserted into the guide slit 51. The receiving portion 44 moves along the guide slit 51. Thereby, it is easy for the receiving portion 44 to move between the receiving position Q1 and the retracted position Q2.

[0071] One or more receiving ports 52 may also be formed in the receiving portion 48 and the guide frame 50. In one example, a plurality of receiving ports 52 are formed in the receiving portion 48. A plurality of receiving ports 52 are formed in the guide frame 50. The receiving port 52 is an opening into which the convex portion 46 is inserted. By inserting the convex portion 46 into the receiving port 52, the receiving portion 43 is held. As a result, the posture of the receiving portion 43 is stabilized.

[0072] The receiving port 52 is formed in the receiving frame 49. In one example, four receiving ports 52 are formed in the receiving frame 49. The four receiving ports 52 are located at positions corresponding to the four convex portions 46 when the receiving portion 43 is in the retracted position Q2. Therefore, by fitting the four convex portions 46 into the four receiving ports 52 formed in the receiving frame 49 respectively, the receiving portion 43 is held in the retracted position Q2.

[0073] In one example, two receiving ports 52 are formed in the guide frame 50. The two receiving ports 52 are located at positions corresponding to the two convex portions 46 when the receiving portion 43 is in the receiving position Q1. When the receiving portion 43 is in the receiving position Q1, the four convex portions 46 are fitted into the two receiving ports 52 formed in the receiving frame 49 and the two receiving ports 52 formed in the guide frame 50. As a result, the receiving portion 43 is held in the receiving position Q1.

[0074] Assembly unit

[0075] Next, the assembly unit 13 will be described.

[0076] As Figure 1 shown, the assembly unit 13 is connected to the liquid ejection device 12. The assembly unit 13 is located adjacent to the liquid ejection device 12. Specifically, the assembly unit 13 is located adjacent to the connection portion 24. In one example, the assembly unit 13 is located below the connection portion 24.

[0077] The assembly unit 13 includes a unit housing 61. The assembly unit 13 is connected to the liquid ejection device 12 by being located in the arrangement space A1. When the assembly unit 13 is connected to the liquid ejection device 12, the surface of the unit housing 61 and the surface of the device housing 14 are in the same plane. For example, the front surface of the unit housing 61 and the front surface of the device housing 14 are in the same plane. The side surface of the unit housing 61 and the side surface of the device housing 14 are in the same plane. The back surface of the unit housing 61 and the back surface of the device housing 14 are in the same plane. As a result, the assembly unit 13 is housed in the bottom space of the liquid ejection device 12.

[0078] The assembly unit 13 includes one or more assemblies 62. In one example, the assembly unit 13 includes a plurality of assemblies 62. The assemblies 62 are assembled to the unit housing 61. The plurality of assemblies 62 are assembled to the unit housing 61 in a manner of being stacked in the vertical direction D2. The assembly 62 is, for example, a box body.

[0079] A liquid container 63 is assembled to the assembly 62. The assembly 62 houses the liquid container 63. The liquid container 63 houses liquid. The liquid container 63 is, for example, an ink pack. The liquid container 63 is detachable from the assembly 62. By assembling the assembly 62 to the unit housing 61, the liquid container 63 is assembled to the assembly unit 13. Thus, the assembly unit 13 can supply liquid from the liquid container 63. The plurality of liquid containers 63 may respectively house the same type of liquid or different types of liquid.

[0080] As Figure 2 shown, the assembly unit 13 includes a unit flow path 64. The unit flow path 64 is configured to allow liquid to flow. The unit flow path 64 is connected to the liquid container 63. Specifically, the unit flow path 64 is connected to the liquid container 63 through the assembly 62. The unit flow path 64 is connected to the assembly 62 and the liquid ejection device 12. The unit flow path 64 is connected to the connection portion 24. Through the unit flow path 64, liquid is supplied from the liquid container 63 to the ejection portion 21.

[0081] The unit flow path 64 has one or more supply portions 65. The supply portion 65 is a portion through which liquid flows. The supply portion 65 is connected to the assembly 62. The supply portion 65 extends within the unit housing 61. The supply portion 65 includes, for example, a tube. The unit flow path 64 has the same number of supply portions 65 as the liquid containers 63. Thus, the unit flow path 64 can supply liquid from the plurality of liquid containers 63 to the ejection portion 21.

[0082] The unit flow path 64 has a connection portion 66. The connection portion 66 is configured to be connected to the liquid ejection device 12. The connection portion 66 is connected to the connection portion 24. The connection portion 66 forms the downstream end of the unit flow path 64. Specifically, the connection portion 66 forms the downstream end of the unit flow path 64 in the direction of liquid flow. The connection portion 66 is connected to the supply portion 65. The connection portion 66 is, for example, a joint.

[0083] As Figure 8 shown, the connection portion 66 is located at a position exposed from the unit housing 61. In one example, the connection portion 66 is exposed in a manner that can be visually confirmed from above the unit housing 61. The connection portion 66 faces the connection portion 24. In one example, the connection portion 66 is vertically opposed to the connection portion 24 when the assembly unit 13 is disposed in the arrangement space A1. The connection portion 66 is fixed to the unit housing 61.

[0084] AsFigure 8 , Figure 9 and Figure 10 As shown in Figure 10 , the connecting portion 66 has a connecting body 67. The connecting body 67 holds the supply portion 65. The connecting body 67 is, for example, a resin housing. The connecting body 67 contacts the connecting portion 24 by being connected to the connecting portion 24. Specifically, the connecting body 67 contacts the connecting body 25.

[0085] The connecting body 67 has a connecting surface 68. The connecting surface 68 is a surface facing the liquid ejecting device 12. The connecting surface 68 faces the connecting portion 24. Specifically, the connecting surface 68 faces the connecting surface 26 when the connecting portion 66 is connected to the connecting portion 24. In one example, the connecting surface 68 faces upward.

[0086] The connecting body 67 may have one or more guide pins 69. In one example, the connecting body 67 has two guide pins 69. The guide pins 69 extend perpendicularly from the connecting surface 68. For example, the guide pins 69 extend upward. The guide pins 69 are inserted into the guide holes 28. Specifically, the guide pins 69 are inserted into the guide holes 28 by the connecting portion 24 being displaced to the connection position P1.

[0087] The connecting portion 66 has one or more connecting tubes 70. The connecting portion 66 has the same number of connecting tubes 70 as the supply portion 65. In one example, the connecting portion 66 has six connecting tubes 70. The connecting tubes 70 are mounted on the connecting body 67. The connecting tubes 70 are located at positions protruding from the connecting surface 68. In one example, the connecting tubes 70 face upward.

[0088] The connecting tubes 70 are connected to the supply portion 65. The connecting portion 66 is connected to the connecting portion 24 by inserting the connecting tubes 70 into the connecting tubes 31, or by inserting the connecting tubes 31 into the connecting tubes 70. In one example, the connecting tubes 31 are inserted into the connecting tubes 70. The connecting tubes 70, for example, have a sealing rubber for sealing the connecting tubes 31. Therefore, when the connecting portion 24 is connected to the connecting portion 66, the connecting tubes 31 are sealed relative to the connecting tubes 70. When the connecting portion 66 is connected to the connecting portion 24, the liquid flows through the connecting tubes 70 to the connecting portion 24.

[0089] As Figure 10 , Figure 11 and Figure 12 shown, the connecting portion 66 has a locking member 71. The locking member 71 is a member that maintains the connecting portion 24 and the connecting portion 66 in a connected state. The locking member 71 is mounted on the connecting body 67. The locking member 71 is mounted on the connecting body 67 so as to be displaceable relative to the connecting body 67. The locking member 71 is configured to move in one direction relative to the connecting body 67.

[0090] The locking member 71 is configured to move between a locking position R1 and a release position R2. In one example, the locking member 71 moves between the locking position R1 and the release position R2 by moving in the conveying direction D3 and the opposite direction thereof. The locking member 71 may also be displaced by moving in the scanning direction D1.

[0091] The locking position R1 is the position where the locking connection portion 24 and the connecting portion 66 are connected. The locking member 71 is displaced to the locking position R1 by moving in the conveying direction D3. The release position R2 is the position where the connection between the connection portion 24 and the connecting portion 66 is released. The locking member 71 is displaced to the release position R2 by moving in the direction opposite to the conveying direction D3. Figure 10 and Figure 11 The locking member 71 shown is in the release position R2. Figure 12 The locking member 71 shown is in the locking position R1.

[0092] The locking member 71 has a locking cover 72. The locking cover 72 is configured to be holdable. For example, the locking cover 72 is held by the user. The user displaces the locking member 71 while holding the locking cover 72.

[0093] The locking cover 72 is located at a position covering a later-described rod 75 at the locking position R1. Therefore, when the locking cover 72 is in the locking position R1, it is difficult for the user to access the rod 75. When the locking cover 72 is displaced to the release position R2, the locking cover 72 separates from the rod 75. Thereby, it becomes easy for the user to access the rod 75. By covering the rod 75, the locking cover 72 can induce the user to operate the rod 75 after operating the locking member 71.

[0094] The locking member 71 has one or more locking pins 73. The locking member 71 has the same number of locking pins 73 as the insertion portion 29. In one example, the locking member 71 has two locking pins 73. The locking pins 73 extend from the locking cover 72. The locking pins 73 extend in one direction. The locking pins 73 extend in the direction in which the locking member 71 moves. In one example, the locking pins 73 extend in the conveying direction D3. The locking pins 73 are inserted into the connecting body 67.

[0095] As Figure 13 shown, the locking pin 73 is inserted into the insertion portion 29. Specifically, the locking pin 73 is inserted into the insertion port 30. The locking pin 73 is on the same axis as the insertion port 30 when the connecting portion 66 is connected to the connecting portion 24. In other words, the insertion portion 29 is on the extension line of the locking pin 73 when the connecting portion 24 is connected to the connecting portion 66. Therefore, the locking pin 73 is inserted into the insertion port 30 by moving in the conveying direction D3 in a state where the connecting portion 66 is connected to the connecting portion 24. By inserting the locking pin 73 into the insertion port 30, the connection between the locking connection portion 24 and the connecting portion 66 is achieved.

[0096] When the locking member 71 is in the locking position R1 before the connecting portion 24 is connected to the connecting portion 66, the locking pin 73 obstructs the connection between the connecting portion 24 and the connecting portion 66. The locking pin 73 interferes with the insertion portion 29 when the connecting portion 24 is displaced to the connection position P1. Therefore, the connecting portion 24 cannot be displaced to the connection position P1. By interfering with the insertion portion 29, the locking pin 73 can induce the user to displace the connecting portion 24 to the connection position P1 while the locking member 71 is in the release position R2.

[0097] The connecting portion 66 has a shaft 74. The shaft 74 is mounted on the connecting body 67. The shaft 74 extends, for example, in the scanning direction D1. The shaft 74 extends, for example, in the scanning direction D1 between the connecting pipe 70 and the guide pin 69 in the conveying direction D3. The shaft 74 supports the rod 75.

[0098] As Figure 14 and Figure 15 shown, the connecting portion 66 has a rod 75. The rod 75 is mounted on the connecting body 67. Specifically, the rod 75 is mounted on the shaft 74. The rod 75 is mounted on the connecting body 67 by being mounted on the shaft 74.

[0099] The rod 75 rotates about the shaft 74. The rod 75 is sandwiched between the connecting portion 24 and the connecting body 67 in a state where the connecting portion 24 is connected to the connecting portion 66. The rod 75 contacts the connecting portion 24 by rotating to separate the connecting portion 24 and the connecting body 67 from each other. Specifically, the rod 75 contacts the connecting body 25 by rotating to separate the connecting body 25 and the connecting body 67 from each other. In one example, the rod 75 acts by rotating to apply a force that displaces the connecting body 25 upward to separate the connecting body 25 from the connecting body 67. When the connecting body 25 and the connecting body 67 are separated from each other, the connection between the connecting portion 24 and the connecting portion 66 is released.

[0100] The rod 75 has a first end portion 76 and a second end portion 77. The first end portion 76 is located between the connecting portion 24 and the connecting body 67. Specifically, the first end portion 76 is located between the connecting body 25 and the connecting body 67. The first end portion 76 is the portion sandwiched between the connecting portion 24 and the connecting body 67. Specifically, the first end portion 76 is the portion sandwiched between the connecting body 25 and the connecting body 67. In one example, the first end portion 76 contacts the pressure receiving portion 27. The first end portion 76 extends so as to avoid the connecting pipe 70. The second end portion 77 is the portion protruding from between the connecting portion 24 and the connecting body 67. The second end portion 77 is not sandwiched between the connecting body 25 and the connecting body 67. Therefore, the second end portion 77 is easily gripped by the user. The second end portion 77 is covered by the locking cover 72 located in the locking position R1.

[0101] The user rotates the rod 75 while holding the second end portion 77. In one example, the user presses the second end portion 77. As a result, the first end portion 76 is lifted. The first end portion 76 pushes up the pressed portion 27 upward. The rod 75 pushes up the connecting portion 24 in such a way that the connecting portion 24 is separated from the connecting portion 66. As a result, the connection between the connecting portion 24 and the connecting portion 66 is released.

[0102] When the connection between the connecting portion 24 and the connecting portion 66 is released, it is sometimes difficult for the connecting portion 24 to disengage from the connecting portion 66. This is because, for example, the sealing rubber of the connecting pipe 70 sometimes adheres closely to the connecting pipe 31. In this regard, the connecting portion 24 can be easily disengaged from the connecting portion 66 by the rod 75.

[0103] As Figure 10 shown, the assembling unit 13 may also include a detection unit 80. The detection unit 80 is configured to detect the connection between the connecting portion 24 and the connecting portion 66. The detection unit 80 is, for example, a contact sensor. The detection unit 80 is mounted on the connecting body 67. When the connecting portion 24 is connected to the connecting portion 66, the detection unit 80 is pressed against the connecting body 25. Thereby, the detection unit 80 detects the connection between the connecting portion 24 and the connecting portion 66. The detection unit 80 may also send a signal indicating the connection between the connecting portion 24 and the connecting portion 66 to the liquid ejecting device 12 by detecting the connection between the connecting portion 24 and the connecting portion 66. The detection unit 80 may also light up a display indicating the connection between the connecting portion 24 and the connecting portion 66 by detecting the connection between the connecting portion 24 and the connecting portion 66.

When the receiving portion 43 is in the receiving position Q1, it is located vertically below the connecting portion 24, thus obstructing the connection between the assembling unit 13 and the connecting portion 24. According to the above structure, when the assembling unit 13 is connected to the connecting portion 24, it can prompt the user to displace the receiving portion 43 to the retracted position Q2.

[0110] (5) The receiving portion 43 has a gripping portion 47 that can be gripped. According to the above structure, it is easy for the user to move the receiving portion 43.

[0111] (6) The holding portion 36 holds the connecting portion 24 in the separated position P2. According to the above structure, it reduces the possibility that the connecting portion 24 accidentally displaces from the separated position P2 to the connecting position P1 due to vibration, impact, etc. It reduces the possibility of collision between the connecting portion 24 and the assembling unit 13.

[0112] (7) The rod 75 contacts the connecting portion 24 by rotation to separate the connecting portion 24 and the connecting body 67 from each other. According to the above structure, the user can easily release the connection between the connecting portion 24 and the connecting portion 66 by rotating the rod 75.

[0113] (8) The first end portion 76 is located between the connecting portion 24 and the connecting body 67. The second end portion 77 protrudes from between the connecting portion 24 and the connecting body 67. According to the above structure, it is easy for the user to grip the second end portion 77. Therefore, it is easy for the user to release the connection of the connecting portion 24 and the connecting portion 66.

[0114] (9) The connecting portion 24 has a connecting body 25, and an insertion port 30 into which the locking pin 73 is inserted is opened on the connecting body 25. According to the above structure, by inserting the locking pin 73 into the insertion port 30, the connecting portion 24 and the connecting portion 66 are maintained in a connected state. Thereby, it reduces the possibility that the connection between the connecting portion 24 and the connecting portion 66 is accidentally released.

[0115] (10) The liquid ejection system 11 includes a detection unit 80 that detects the connection between the connecting portion 24 and the connecting portion 66. According to the above structure, it reduces the possibility of a defect occurring in the connection between the connecting portion 24 and the connecting portion 66.
