[0020] Hereinafter, an embodiment of a recording device will be described with reference to the drawings. The recording device is, for example, an inkjet printer that records images such as text and photos by ejecting ink, which is an example of liquid, onto a medium such as paper or cloth.

[0021] Recording device

[0022] like Figure 1 As shown, the recording device 11 includes a device body 12. The device body 12 is configured to record an image on a medium M1. The device body 12 will be described in detail later. The recording device 11 may be a multifunction device having not only a function of recording an image on a medium M1 but also other functions.

[0023] The recording device 11 may also include a reading unit 13. The reading unit 13 is configured to read an image recorded on a manuscript. The reading unit 13 is a scanner. The reading unit 13 reads images sequentially by automatically feeding the placed manuscript. The reading unit 13 is mounted on the device body 12. The reading unit 13 is mounted at the upper part of the device body 12. The reading unit 13 overlaps with the device body 12 when viewed from the vertical direction D3.

[0024] The recording device 11 includes an operation unit 14. The operation unit 14 is an interface for a user to operate the recording device 11. The operation unit 14 is, for example, a touch panel. The operation unit 14 may also include buttons, levers, switches, etc. The operation unit 14 is located in front of the device body 12 and the reading unit 13.

[0025] Device body

[0026] The device body 12 has a shell 15. The shell 15 accommodates various structures of the device body 12. The shell 15 is in the shape of a rectangular parallelepiped. The shell 15 has depth, width, and height. The depth of the shell 15 is the length of the shell 15 in the first direction D1. The width of the shell 15 is the length of the shell 15 in the second direction D2. The height of the shell 15 is the length of the shell 15 in the vertical direction D3. The first direction D1 is a direction different from the second direction D2 and the vertical direction D3. The first direction D1 is a direction from the front to the depth of the shell 15. The second direction D2 is a direction different from the vertical direction D3. The second direction D2 is a direction from the left to the right when the shell 15 is observed from the first direction D1. The first direction D1 and the second direction D2 indicate the directions in which the setting surface on which the device body 12 is set extends.

[0027] The housing 15 has a plurality of surfaces. The housing 15 has a front surface 16, a rear surface 17, and two side surfaces. Specifically, the housing 15 has a front surface 16, a rear surface 17, a first side surface 18, and a second side surface 19. The front surface 16 faces a direction opposite to the first direction D1. In one example, the front surface 16 faces the same direction as the operating unit 14. The front surface 16 is a surface facing a user who operates the recording device 11. The rear surface 17 is a surface opposite to the front surface 16. The rear surface 17 faces the first direction D1. The front surface 16 and the rear surface 17 extend in the second direction D2 and the vertical direction D3. The first side surface 18 faces a direction opposite to the second direction D2. The first side surface 18 faces a direction different from the front surface 16, the rear surface 17, and the second side surface 19. The second side surface 19 faces a direction opposite to the first side surface 18. The second side surface 19 faces the second direction D2. The first side surface 18 and the second side surface 19 extend in the first direction D1 and the vertical direction D3.

[0028] The housing 15 is shaped as if a portion is hollowed out from a rectangular parallelepiped. A recess 20 is formed on the housing 15. In one example, the recess 20 is provided in a manner that a corner of the housing 15 is hollowed out. The recess 20 is provided, for example, in a manner that the front surface 16 and the first side surface 18 are recessed. The recess 20 is located below the reading unit 13.

[0029] The housing 15 defines the discharge space S1. The discharge space S1 is a space for discharging the recorded medium M1. The discharge space S1 is formed by the recess 20. The discharge space S1 is a space outside the housing 15. The medium M1 discharged from the housing 15 is accumulated in the discharge space S1. In one example, the discharge space S1 is a space surrounded by the reading unit 13 and the housing 15. The discharge space S1 is exposed through the front surface 16 and the first side surface 18. Therefore, the user can approach the discharge space S1 from a position opposite to the front surface 16. The user can approach the discharge space S1 from a position opposite to the first side surface 18.

[0030] The housing 15 may have more than one cover. In one example, the housing 15 has a front cover 21. The front cover 21 forms the front surface 16. The front cover 21 is configured to be openable and closable. By opening the front cover 21, the inside of the housing 15 is exposed.

[0031] The housing 15 may include a side cover 22. The side cover 22 is a cover that constitutes the first side surface 18. The side cover 22 is configured to be openable and closable. By opening the side cover 22, the inside of the housing 15 is exposed.

[0032] One or more through-holes 23 may be formed on the housing 15. The through-holes 23 are open on one surface of the housing 15. In one example, the through-holes 23 are open on the first side surface 18. The through-holes 23 are open on the side cover 22, for example. The through-holes 23 are not limited to being opened on the first side surface 18, and may be opened on the rear surface 17, for example. The through-holes 23 allow the inside and outside of the housing 15 to be connected. The through-holes 23 allow air to flow into the housing 15 from outside the housing 15, or allow air to flow out of the housing 15 from inside the housing 15.

[0033] One or more vents 24 may be formed on the housing 15. The vent 24 opens on one surface of the housing 15. That is, the vent 24 opens on the first side surface 18. The vent 24 opens on the same surface as the through-hole 23. The vent 24 opens on the side cover 22, for example. The vent 24 is located below the through-hole 23. The vent 24 allows the inside and outside of the housing 15 to be connected. The air flows into the housing 15 from the outside through the vent 24, or the air flows out from the inside of the housing 15 to the outside. The air flows across the inside and outside of the housing 15 through the through-hole 23 and the vent 24.

[0034] like Figure 2 As shown, the through-hole 23 and the vent 24 allow the inside and outside of the housing 15 to communicate with each other, thereby cooling the substrate 81 described later. The uppermost end of the through-hole 23 is located above the uppermost end of the substrate 81. The lowermost end of the vent 24 is located below the lowermost end of the substrate 81. By causing the air to flow from the through-hole 23 toward the vent 24, or causing the air to flow from the vent 24 toward the through-hole 23, the air flows across the entire length of the substrate 81 in the vertical direction D3. Thus, the substrate 81 is effectively cooled.

[0035] The through-hole 23 overlaps with the flow channel 62 described later when viewed from the first direction D1. Thus, the flow channel 62 is effectively cooled. The vent 24 may overlap with the flow channel 62 when viewed from the first direction D1. In this case, the flow channel 62 is further cooled.

[0036] like Figure 3 As shown, an exposure port 25 may be opened on the housing 15. The exposure port 25 opens in the upper portion of the housing 15. The exposure port 25 opens in the recess 20. The exposure port 25 is defined by, for example, the front cover 21, the side cover 22, etc. The exposure port 25 exposes the inside of the housing 15. The user can perform maintenance on the device body 12 through the exposure port 25.

[0037] like Figure 4 As shown, the device body 12 has a frame portion 31. The frame portion 31 is housed in the housing 15. The frame portion 31 is covered by the housing 15, thereby defining the discharge space S1. Therefore, it can also be said that the frame portion 31 defines the discharge space S1.

[0038] The frame portion 31 supports the reading portion 13. The frame portion 31 supports the operation portion 14. The frame portion 31 supports the housing 15. The frame portion 31 defines a frame space A1. The frame space A1 is a space surrounded by the frame portion 31. That is, the frame space A1 is a space inside the frame portion 31. The frame space A1 is a space inside the housing 15. Various structures included in the device body 12 are located in the frame space A1. The frame portion 31 supports various structures housed in the housing 15.

[0039] The frame portion 31 has more than one frame. In one example, the frame portion 31 has a first frame 32, a second frame 33, and a third frame 34. The first frame 32, the second frame 33, and the third frame 34 define the frame space A1. The frame is made of metal, for example. Thus, the rigidity of the device body 12 can be ensured.

[0040] The first frame 32 and the second frame 33 are arranged in one direction. In one example, the first frame 32 and the second frame 33 are arranged in the first direction D1. The first frame 32 is located at the front in the device body 12. The first frame 32 is, for example, a front frame. The second frame 33 is located closer to the first direction D1 than the first frame 32. The second frame 33 is located at the rear in the device body 12. The second frame 33 is, for example, a rear frame. The third frame 34 connects the first frame 32 and the second frame 33. The third frame 34 is located at the side in the device body 12. The third frame 34 is, for example, a side frame. The third frame 34 is mounted on the first frame 32 and the second frame 33.

[0041] The second frame 33 has a frame wall 35. The frame wall 35 extends in the second direction D2 and the vertical direction D3. The frame wall 35 is a wall that divides the inside and outside of the frame portion 31. The frame wall 35 divides the inside and outside of the frame portion 31 in the housing 15. In the housing 15, a space closer to the first direction D1 than the frame wall 35 is a space outside the frame portion 31. In the housing 15, a space in the opposite direction of the first direction D1 than the frame wall 35 is a space inside the frame portion 31.

[0042] The third frame 34 has one or more frame parts. In one example, the third frame 34 has a first frame part 36, a second frame part 37, and a third frame part 38. The frame parts connect the first frame 32 and the second frame 33. The frame parts extend in the first direction D1. The frame parts are plates extending in the first direction D1 and the vertical direction D3.

[0043] The plurality of frame members may be provided in a manner that they are separated from each other in the vertical direction D3. In one example, the first frame member 36, the second frame member 37, and the third frame member 38 are provided in a manner that they are spaced apart in the vertical direction D3. For example, the first frame member 36, the second frame member 37, and the third frame member 38 are arranged in this order in the vertical direction D3.

[0044] The frame member is mounted on the first frame 32 and the second frame 33. The first frame member 36 may be welded to the first frame 32 and the second frame 33. In this case, the rigidity of the frame portion 31 can be improved. The frame member may be screwed to the first frame 32 and the second frame 33. In this case, the frame member is removable relative to the first frame 32 and the second frame 33. By removing the frame member, the user can approach the frame portion 31 from the side of the device body 12. Therefore, the maintainability of the device body 12 can be improved.

[0045] like Figure 5 As shown, the device body 12 has a storage section 41. The storage section 41 is configured to store the medium M1. In the storage section 41, a plurality of mediums M1 are stored, for example, in a stacked state. The storage section 41 is mounted on the housing 15. The storage section 41 is located at the lower part of the housing 15. In one example, the storage section 41 is configured to be pluggable relative to the housing 15. The storage section 41 is, for example, a box. The storage section 41 is, for example, pluggable relative to the front surface 16. The user can replenish the medium M1 to the storage section 41 by pulling out the storage section 41 from the housing 15. The storage section 41 is not limited to a box, and may also be a tray.

[0046] The device body 12 has a conveying passage 42. The conveying passage 42 is a path for conveying the medium M1. The conveying passage 42 extends inside the housing 15. The conveying passage 42 extends from inside the housing 15 toward outside the housing 15. Specifically, the conveying passage 42 extends from the storage portion 41 toward the discharge space S1. The medium M1 is recorded with an image while being conveyed on the conveying passage 42.

[0047] The device body 12 has a conveying unit 43. The conveying unit 43 is configured to convey the medium M1. The conveying unit 43 conveys the medium M1 stored in the storage unit 41. The conveying unit 43 conveys the medium M1 along the conveying path 42. The conveying unit 43 has one or more rollers 44. In one example, the conveying unit 43 has a plurality of rollers 44. The plurality of rollers 44 are arranged along the conveying path 42. The plurality of rollers 44 convey the medium M1 by rotating individually.

[0048] The device body 12 has a support portion 45. The support portion 45 is configured to support the medium M1. The support portion 45 supports the medium M1 transported from the storage portion 41. The support portion 45 supports the medium M1 transported in the transport path 42. In one example, the support portion 45 supports the medium M1 in an inclined posture relative to the horizontal. The support portion 45 supports the medium M1 by adsorbing it. As a result, the posture of the medium M1 is relatively stable. The support portion 45 can also support the medium M1 in a horizontal posture.

[0049] The support portion 45 may also be configured to transport the medium M1. In one example, the support portion 45 includes a conveyor belt 46, a first pulley 47, and a second pulley 48. The conveyor belt 46 is wound around the first pulley 47 and the second pulley 48. The conveyor belt 46 adsorbs the medium M1, for example, by static electricity. Thus, the conveyor belt 46 supports the medium M1. The conveyor belt 46 may also be configured to adsorb the medium M1 by negative pressure generated by suction, for example. The conveyor belt 46 is rotated by rotating the first pulley 47 and the second pulley 48. As a result, the medium M1 supported on the conveyor belt 46 is transported. The conveyor belt 46 transports the medium M1, for example, diagonally upward. The support portion 45 may also be only a support table.

[0050] The device body 12 includes a recording unit 49. The recording unit 49 is configured to record an image on the medium M1. The recording unit 49 records an image on the medium M1 by ejecting liquid onto the medium M1. The recording unit 49 faces the support unit 45. The recording unit 49 records an image on the medium M1 supported by the support unit 45.

[0051] The recording unit 49 extends in one direction. Specifically, the recording unit 49 extends in the first direction D1. The recording unit 49 includes a line head capable of ejecting liquid all at once across the entire width of the medium M1. The recording unit 49 includes a head 50. The head 50 includes an ejection surface 52 in which one or more nozzles 51 are opened. The head 50 ejects liquid from the nozzles 51. The ejection surface 52 is opposite to the medium M1. The ejection surface 52 is opposite to the support portion 45.

[0052] The recording unit 49 includes a head control unit 53. The head control unit 53 is configured to control the head 50. The head control unit 53 controls the ejection of the liquid by controlling the head 50. The head control unit 53 is located above the head 50. In one example, the head control unit 53 is located on the upper surface of the head 50. The upper surface of the head 50 is the surface opposite to the ejection surface 52 in the head 50. The head control unit 53 is connected to a substrate 81 described later. The head control unit 53 is connected to the substrate 81, for example, by an electric wire, a signal line, or the like.

[0053] The head control unit 53 may also be composed of one or more processors that execute various processes according to a computer program. The head control unit 53 may also be composed of one or more dedicated hardware circuits such as an ASIC (Application Specific Integrated Circuit) that executes at least a part of the various processes. The head control unit 53 may also be composed of a circuit including a combination of a processor and a hardware circuit. The processor includes a CPU (Central Processing Unit) and memories such as RAM (Random Access Memory) and ROM (Read-Only Memory). The memory stores program codes or instructions that are configured in such a way that the CPU executes the process. The memory, i.e., the computer-readable medium, includes all general or dedicated readable media that can be accessed by a computer.

[0054] The recording unit 49 has a joint 54. The joint 54 is connected to the supply unit 57. Liquid is supplied to the head 50 through the joint 54. The joint 54 is located above the head 50. In one example, the joint 54 is located on a side surface of the head 50. Specifically, the joint 54 is located on a side surface facing upward among a plurality of side surfaces of the head 50.

[0055] The recording unit 49 is accommodated in the housing 15. The recording unit 49 is supported by the frame portion 31. Specifically, the recording unit 49 is supported by the first frame 32 and the second frame 33. The recording unit 49 is mounted on the first frame 32 and the second frame 33, for example.

[0056] The recording unit 49 is located below the discharge space S1 in the housing 15. The space located at the same height as the discharge space S1 in the housing 15 has a small volume due to the recess 20. On the other hand, the space located below the discharge space S1 in the housing 15 has a large volume. The recording unit 49 is located in the large space, so that it is easy to record an image on the medium M1.

[0057] The recording unit 49 is configured to be displaced between the recording position P1 and the retreat position P2. The recording unit 49 is displaced between the recording position P1 and the retreat position P2 by moving in a direction perpendicular to the ejection surface 52. The recording unit 49 is displaced by a mechanism such as a rack and pinion, a ball screw, etc.

[0058] The recording position P1 is the position at which the recording unit 49 performs recording on the medium M1. That is, the recording position P1 is the position at which the liquid is ejected onto the medium M1 supported by the support unit 45. Figure 5The solid line in FIG. 4 shows the position of the recording section 49 . At the recording position P1 , the recording section 49 is close to the support section 45 .

[0059] The retreat position P2 is a position where the recording unit 49 is retreated from the support unit 45. That is, the retreat position P2 is a position further away from the support unit 45 than the recording position P1. Therefore, the distance between the recording unit 49 at the retreat position P2 and the support unit 45 is greater than the distance between the recording unit 49 at the recording position P1 and the support unit 45. The retreat position P2 is Figure 5 The position of the recording section 49 is indicated by the double-dashed line in FIG.

[0060] The retreat position P2 may include a position when the user replaces the recording unit 49 and a position when maintenance is performed by the maintenance unit 55 described later. In this case, the position when the recording unit 49 is replaced may be closer to the exposure port 25 than the position when maintenance is performed.

[0061] The recording unit 49 is provided so as to be exposed from the exposure opening 25 when the loading unit 71 described later is set to an open state. In one example, the recording unit 49 is exposed from the exposure opening 25 at both the recording position P1 and the retreat position P2. The head control unit 53 and the connector 54 in the recording unit 49 can be exposed from the exposure opening 25. In this case, it is easy for a user to pass through the exposure opening 25 and approach the head control unit 53 and the connector 54. This is because the head control unit 53 and the connector 54 are located above the head 50. The user can easily replace the recording unit 49.

[0062] The recording unit 49 overlaps with the support unit 45 when viewed from the second direction D2. Specifically, when viewed from the second direction D2, the head 50 overlaps with the conveyor belt 46. In one example, when viewed from the second direction D2, the head 50 at the recording position P1 overlaps with the conveyor belt 46. When viewed from the second direction D2, the head 50 at the retreat position P2 also overlaps with the conveyor belt 46.

[0063] The device body 12 has a maintenance unit 55. The maintenance unit 55 is configured to perform maintenance on the recording unit 49. The maintenance unit 55 performs maintenance on the head 50. Specifically, the maintenance unit 55 performs maintenance on the head 50 by flushing, capping, cleaning, and the like. Flushing is the action of the head 50 appropriately ejecting liquid from the nozzle 51. By flushing, clogging of the nozzle 51 is suppressed. The maintenance unit 55 receives the liquid generated by flushing. Capping is the action of moisturizing the nozzle 51. By capping, clogging of the nozzle 51 is suppressed. The maintenance unit 55 forms a space communicating with the nozzle 51 by contacting with the head 50. Cleaning is the action of discharging liquid from the nozzle 51. By cleaning, foreign matter is discharged from the head 50 together with the liquid. The maintenance unit 55 discharges the liquid from the nozzle 51 by performing suction.

[0064] The maintenance unit 55 is configured to be displaceable. The maintenance unit 55 is displaced, for example, by a rack and pinion, a ball screw, etc. When the recording unit 49 is to be maintained, the maintenance unit 55 is located at the maintenance position. The maintenance position is a position between the support unit 45 and the recording unit 49. In the maintenance position, the maintenance unit 55 is opposite to the ejection surface 52. When the recording unit 49 is not to be maintained, the maintenance unit 55 is located at the standby position. The standby position is a position retreated from between the support unit 45 and the recording unit 49. Figure 5 The maintenance section 55 is shown in a standby position.

[0065] A waste liquid tank 56 may also be installed on the device body 12. The waste liquid tank 56 is a tank for storing liquid discharged due to maintenance. The waste liquid tank 56 is connected to the maintenance unit 55. The waste liquid tank 56 stores liquid received by the maintenance unit 55 due to flushing, cleaning, etc. In one example, the waste liquid tank 56 is a replaceable tank.

[0066] The waste liquid tank 56 overlaps with the maintenance unit 55 when viewed from the second direction D2. Specifically, the waste liquid tank 56 overlaps with the maintenance unit 55 at the standby position when viewed from the second direction D2. The waste liquid tank 56 may overlap with the maintenance unit 55 at the maintenance position when viewed from the second direction D2. The waste liquid tank 56 is mounted on the device body 12 so that the waste liquid tank 56 overlaps with the maintenance unit 55 when viewed from the second direction D2.

[0067] The device body 12 includes a supply unit 57. The supply unit 57 is configured to supply liquid to the recording unit 49. The supply unit 57 is connected to the recording unit 49. The supply unit 57 is connected to the joint 54. The supply unit 57 is located between the third frame 34 and the conveying unit 43 when viewed from the first direction D1. That is, in the first direction D1, the distance between the third frame 34 and the supply unit 57 is smaller than the distance between the third frame 34 and the conveying unit 43. Therefore, the conveying unit 43 is close to the second side surface 19, and the supply unit 57 is close to the first side surface 18.

[0068] The supply unit 57 has a mounting unit 58. The mounting unit 58 is configured to mount one or more storage bodies 59. In one example, four storage bodies 59 are mounted on the mounting unit 58. Specifically, four storage bodies 59 are mounted on the mounting unit 58 in a state of being arranged in the second direction D2. The storage body 59 is configured to store liquid. The storage body 59 is, for example, an ink cartridge. The four storage bodies 59 store different types of liquids, respectively. The four storage bodies 59 store different colors of liquids, respectively.

[0069] The storage body 59 overlaps with the recording unit 49 when viewed from the second direction D2. Specifically, the storage body 59 overlaps with the head 50 located at the recording position P1 when viewed from the second direction D2. The storage body 59 also overlaps with the head 50 located at the retreat position P2 when viewed from the second direction D2. The storage body is mounted on the mounting portion 58 so that the storage body 59 overlaps with the recording unit 49 when viewed from the second direction D2.

[0070] The storage body 59 overlaps with the support portion 45 when viewed from the second direction D2. That is, the storage body 59 is attached to the attachment portion 58 so that the storage body 59 overlaps with the support portion 45 when viewed from the second direction D2.

[0071] The mounting portion 58 has a storage portion 60. The storage portion 60 is configured to mount the storage body 59. The storage portion 60 is configured to store the liquid supplied from the storage body 59. The storage portion 60 individually stores a plurality of liquids supplied from the plurality of storage bodies 59. The storage portion 60 is located below the storage body 59.

[0072] The storage part 60 stores the liquid in such a manner that the liquid level is located at the reference position L1. The storage part 60 receives the liquid from the storage body 59 so that the liquid level is maintained at the reference position L1. In one example, the inside of the storage part 60 is opened to the atmosphere. The liquid is automatically supplied from the storage body 59 to the storage part 60 by the atmospheric pressure. When the liquid level is lower than the reference position L1, the liquid is supplied from the storage body 59 to the storage part 60. When the liquid level reaches the reference position L1, the supply of the liquid from the storage body 59 to the storage part 60 stops.

[0073] The reference position L1 is located below the head 50. Specifically, the reference position L1 is located below the ejection surface 52. The storage portion 60 supplies liquid according to the water level difference with the recording portion 49. Therefore, since the reference position L1 is located below the ejection surface 52, negative pressure is generated in the head 50. As a result, a meniscus can be formed in the nozzle 51. Therefore, the head 50 can eject liquid appropriately.

[0074] The mounting portion 58 has a relay component 61. The relay component 61 is a component that relays the storage portion 60 and the recording portion 49. The relay component 61 is, for example, a flow channel component in which a resin plate is attached to a resin base having grooves formed thereon. The relay component 61 is connected to the storage portion 60. The liquid stored in the storage portion 60 flows in the relay component 61. The relay component 61 extends below the storage portion 60. The relay component 61 extends in the first direction D1. The relay component 61 extends below the storage portion 60 toward the rear of the storage portion 60.

[0075] The supply unit 57 has a flow channel 62. Liquid flows in the flow channel 62. The flow channel 62 is a flexible tube. In one example, the flow channel 62 is a multi-tube for flowing multiple liquids. The flow channel 62 can also be composed of multiple tubes that are pulled and aligned. The flow channel 62 is connected to the mounting unit 58 and the recording unit 49. In detail, the flow channel 62 is connected to the relay component 61 and the connector 54.

[0076] The flow channel 62 has a first end 63 and a second end 64. The first end 63 is connected to the mounting portion 58. Specifically, the first end 63 is connected to the relay component 61. The second end 64 is connected to the recording portion 49. Specifically, the second end 64 is connected to the connector 54. Therefore, the distance between the first end 63 and the mounting portion 58 is smaller than the distance between the first end 63 and the recording portion 49. The distance between the second end 64 and the recording portion 49 is smaller than the distance between the second end 64 and the mounting portion 58.

[0077] The first end 63 and the second end 64 are arranged so as to sandwich the center of the mounting portion 58 when viewed from the first direction D1. In one example, the first end 63 is located in the opposite direction of the center line L2 and closer to the second direction D2. The center line L2 is an imaginary line that divides the mounting portion 58 into two parts in the second direction D2. The center line L2 extends in the vertical direction D3. The center line L2 is an imaginary line that passes through the center position of the mounting portion 58 in the second direction D2. The second end 64 is located closer to the second direction D2 than the center line L2. That is, the first end 63 and the second end 64 are arranged so as to sandwich the center line L2 in the second direction D2. As a result, the curvature of the flow channel 62 can be reduced. Assuming that both the first end 63 and the second end 64 are located closer to the second direction D2 than the center line L2, the curvature of the flow channel 62 will increase. In this case, the flow channel 62 may be bent into an acute angle. When the flow channel 62 is constituted by a plurality of tubes, the first end 63 and the second end 64 of at least one of the plurality of tubes may be provided so as to sandwich the center line L2 .

[0078] The flow channel 62 has an upper portion 65. The upper portion 65 is a portion including the top of the flow channel 62. That is, the upper portion 65 includes a portion located at the vertex of the flow channel 62. The upper portion 65 is a portion located between the first end 63 and the second end 64. The upper portion 65 includes a portion that is curved in a convex manner upward.

[0079] The flow channel 62 overlaps with the discharge space S1 when viewed from the first direction D1. Specifically, the upper portion 65 overlaps with the discharge space S1 when viewed from the first direction D1. The upper portion 65 is located in the flow channel space A3 described later. Since the flow channel 62 overlaps with the discharge space S1 when viewed from the first direction D1, the curvature of the flow channel 62 can be reduced compared with a case where the flow channel 62 and the discharge space S1 do not overlap, for example, a case where the flow channel 62 is accommodated below the discharge space S1. In order to reduce the curvature of the flow channel 62 when the flow channel 62 is accommodated below the discharge space S1, it is considered to increase the frame space A1 in the vertical direction D3. In this case, although it is possible to enlarge the device body 12 in the vertical direction D3, by arranging the flow channel 62 in a manner overlapping with the discharge space S1, the possibility of enlarging the device body 12 in the vertical direction D3 can be reduced.

[0080] The flow channel 62 overlaps with the mounting portion 58 when viewed from the first direction D1. Specifically, a portion of the flow channel 62 including the first end 63 overlaps with the storage portion 60 when viewed from the first direction D1. The flow channel 62 extends upward from the relay member 61. The flow channel 62 extends straight upward from the rear of the storage portion 60. The flow channel 62 extends upward from the first end 63 toward the second end 64, and then extends in the second direction D2. The flow channel 62 extends along the second frame 33. Specifically, the flow channel 62 extends along the frame wall 35 from the first end 63 to the second end 64.

[0081] The flow channel 62 overlaps with the housing 59 when viewed from the first direction D1. That is, the housing 59 is mounted on the mounting portion 58 in such a manner that the flow channel 62 overlaps with the housing 59 when viewed from the first direction D1. In one example, a portion of the flow channel 62 between the first end 63 and the upper portion 65 overlaps with the housing 59 when viewed from the first direction D1.

[0082] The supply portion 57 overlaps with the waste liquid tank 56 when viewed from the second direction D2. Specifically, the mounting portion 58 overlaps with the waste liquid tank 56 when viewed from the second direction D2. More specifically, the storage portion 60 overlaps with the waste liquid tank 56 when viewed from the second direction D2. That is, the waste liquid tank 56 is mounted on the device body 12 in such a manner that the storage portion 60 overlaps with the waste liquid tank 56.

[0083] The supply portion 57 overlaps with the maintenance portion 55 when viewed from the second direction D2. Specifically, the mounting portion 58 overlaps with the maintenance portion 55 when viewed from the second direction D2. In further detail, the storage portion 60 overlaps with the maintenance portion 55 when viewed from the second direction D2. In one example, the storage portion 60 overlaps with the maintenance portion 55 at the standby position when viewed from the second direction D2. The storage portion 60 may also overlap with the maintenance portion 55 at the maintenance position when viewed from the second direction D2.

[0084] The supply portion 57 may overlap with the recording portion 49 when viewed from the second direction D2. The supply portion 57 may overlap with the recording portion 49 at the recording position P1 or at the retreat position P2 when viewed from the second direction D2. For example, the mounting portion 58 may overlap with the recording portion 49 when viewed from the second direction D2. In one example, the storage portion 60 overlaps with the recording portion 49 when viewed from the second direction D2. Specifically, when viewed from the second direction D2, the storage portion 60 overlaps with the head 50 in a state where the reference position L1 is located below the ejection surface 52.

[0085] like Figure 1 As shown, the device body 12 has a loading section 71. The loading section 71 receives the medium M1 discharged from the housing 15. Therefore, the loading section 71 is loaded with the medium M1 on which recording is performed. The loading section 71 receives the medium M1 discharged into the discharge space S1. That is, the loading section 71 is loaded with the medium M1 discharged into the discharge space S1. The loading section 71 is, for example, a stacker.

[0086] The loading portion 71 is mounted on the housing 15. The loading portion 71 is supported by the frame portion 31. The loading portion 71 is accommodated in the recess 20. In one example, the loading portion 71 is mounted on the housing 15 so as to close the exposure opening 25.

[0087] The loading portion 71 may also be configured to be displaced between an open state and a closed state. The open state is a state in which the exposure opening 25 is exposed. The closed state is a state in which the exposure opening 25 is closed. In one example, the loading portion 71 is freely detachable relative to the housing 15. The loading portion 71 is detachable relative to the housing 15 to open or close the exposure opening 25. The loading portion 71 closes the exposure opening 25 to separate the inside of the housing 15 from the outside of the housing 15. The loading portion 71 may also be opened and closed or slid relative to the housing 15, for example, to open or close the exposure opening 25.

[0088] The loading section 71 is located above the recording section 49. The loading section 71 is located above the mounting section 58. The loading section 71 overlaps the reading section 13 when viewed from the vertical direction D3. The loading section 71 is located directly below the reading section 13.

[0089] like Figure 6As shown, the loading portion 71 defines the storage space A2 and the flow channel space A3. The storage space A2 and the flow channel space A3 are part of the frame space A1. The storage space A2 is a space that stores various structures of the device body 12. The flow channel space A3 is a space that stores the flow channel 62. The storage space A2 and the flow channel space A3 are connected to each other. The storage space A2 is defined by the loading portion 71, the first frame 32 and the second frame 33. The flow channel space A3 is defined by the loading portion 71 and the second frame 33. In one example, the flow channel space A3 is defined by the loading portion 71, the second frame 33 and the reading portion 13. The flow channel space A3 is a space sandwiched by the loading portion 71 and the second frame 33. The flow channel space A3 is located between the loading portion 71 and the second frame 33 in the first direction D1. When viewed from the first direction D1, the flow channel space A3 overlaps with the discharge space S1.

[0090] The storage space A2 communicates with the vent 24. Therefore, air flows into the storage space A2 from outside the housing 15 through the vent 24, or air flows out of the storage space A2 to outside the housing 15. The present invention is not limited thereto, and air may also enter and exit the storage space A2 through a gap in the housing 15.

[0091] The flow channel space A3 communicates with the through-hole 23. Therefore, air flows into the flow channel space A3 from outside the housing 15 through the through-hole 23, or air flows out of the flow channel space A3 to outside the housing 15. The present invention is not limited to this, and air may also enter and exit the flow channel space A3 through a gap in the housing 15.

[0092] The flow channel space A3 is a space where the flow channel 62 is located. Specifically, the flow channel space A3 is a space where the upper portion 65 is located. That is, in the flow channel space A3, a curved portion is provided on the flow channel 62. Therefore, the loading unit 71, the second frame 33, and the reading unit 13 surround the upper portion 65. Thus, the flow channel 62 is protected. By locating the flow channel 62 in the flow channel space A3, the curvature of the flow channel 62 can be reduced compared to the case where the flow channel 62 is accommodated only in the storage space A2.

[0093] like Figure 7As shown, the loading portion 71 has a loading plate 72. The loading plate 72 is a portion for receiving the medium M1 discharged to the discharge space S1. In one example, the loading plate 72 is inclined in a downward direction in the second direction D2. The loading plate 72 separates the storage space A2 and the discharge space S1. In detail, the loading plate 72 separates the storage space A2 and the discharge space S1 in the vertical direction D3. The discharge space S1 is located above the loading plate 72. The storage space A2 is located below the loading plate 72. Therefore, by making the flow channel 62 located in the flow channel space A3, the loading plate 72 is located below the upper portion 65.

[0094] The loading portion 71 has a loading surface 72A. The loading surface 72A is a surface of the loading plate 72 that receives the medium M1. The loading surface 72A is a surface facing upward in the loading plate 72. The loading plate 72 is not limited to being composed of a single plate, but may also be composed of a plurality of components. In this case, the loading surface 72A is also the upper surface of the loading plate 72.

[0095] The loading portion 71 has a calibration plate 73. The calibration plate 73 extends upward from the loading plate 72. Specifically, the calibration plate 73 extends upward from the end of the loading plate 72 in the second direction D2. The calibration plate 73 extends in the first direction D1 and the vertical direction D3. The calibration plate 73 separates the storage space A2 and the discharge space S1. Specifically, the calibration plate 73 separates the storage space A2 and the discharge space S1 in the second direction D2.

[0096] The calibration plate 73 calibrates the medium M1 loaded on the loading plate 72 by contacting the medium M1. Specifically, when the medium M1 is discharged to the loading portion 71, it slides in the second direction D2 along the inclined loading plate 72. As a result, the base end of the medium M1 contacts the calibration plate 73. As a result, the base ends of the plurality of media M1 are aligned. Thus, the medium M1 is calibrated.

[0097] The loading portion 71 has a partition plate 74. The partition plate 74 extends from the loading plate 72. In one example, the partition plate 74 extends from the loading plate 72 and the calibration plate 73. The partition plate 74 extends upward from the loading plate 72. In detail, the partition plate 74 extends upward from the end of the loading plate 72 in the first direction D1. The partition plate 74 extends in the second direction D2 and the vertical direction D3. The partition plate 74 defines the flow channel space A3. The partition plate 74 separates the flow channel space A3 and the discharge space S1. In detail, the partition plate 74 separates the flow channel space A3 and the discharge space S1 in the first direction D1. The discharge space S1 is located in the opposite direction of the first direction D1 compared to the partition plate 74. The flow channel space A3 is located in the first direction D1 compared to the partition plate 74. Therefore, by positioning the flow channel 62 in the flow channel space A3 , the partition plate 74 overlaps the upper portion 65 when viewed from the first direction D1 .

[0098] A partition opening 75 may also be formed on the loading portion 71. The partition opening 75 opens on the partition plate 74. Through the partition opening 75, the inside and outside of the shell 15 are communicated. In detail, the exhaust space S1 and the flow channel space A3 in the shell 15 are communicated through the partition opening 75. Through the partition opening 75, air flows into the flow channel space A3 from the outside of the shell 15, or air flows out of the flow channel space A3 to the outside of the shell 15. Through the through-port 23, the vent 24 and the partition opening 75, the air flows across the inside and outside of the shell 15. It is not limited to the through-port 23, the vent 24 and the partition opening 75, and the air may also flow to the inside and outside of the shell 15 through the gap of the shell 15.

[0099] The loading portion 71 does not overlap with the flow channel 62 when viewed from the vertical direction D3. Specifically, the loading plate 72 does not overlap with the upper portion 65 when viewed from the vertical direction D3. That is, the loading surface 72A does not overlap with the upper portion 65 when viewed from the vertical direction D3. Thus, the possibility of interference between the flow channel 62 and the medium M1 loaded on the loading plate 72 can be reduced.

[0100] like Figure 8 as well as Fig. 9 As shown, the device body 12 includes a substrate 81. The substrate 81 may be a power substrate for controlling power supplied to the device body 12 or a control substrate for controlling driving of the device body 12.

[0101] The substrate 81 is mounted on the frame portion 31. Specifically, the substrate 81 is mounted on the second frame 33. In one example, the substrate 81 is fixed to the second frame 33 so as not to be displaced. For example, the substrate 81 is mounted to the second frame 33 so as to be opened and closed.

[0102] like Fig.10 As shown, the substrate 81 is arranged along the frame wall 35. The substrate 81 can be arranged in a manner close to the frame wall 35 or in a manner separated from the frame wall 35. The substrate 81 is located outside the frame space A1. The substrate 81 is located closer to the first direction D1 than the frame wall 35. The substrate 81 and the supply portion 57 are arranged in a manner of sandwiching the frame wall 35 in the first direction D1. That is, the frame wall 35 is located between the substrate 81 and the supply portion 57 when viewed from the second direction D2. In other words, the frame wall 35 is located between the substrate 81 and the supply portion 57 when viewed from the vertical direction D3. Therefore, the substrate 81 is close to the supply portion 57. In particular, the substrate 81 is close to the flow channel 62.

[0103] The substrate 81 is located closer to the first direction D1 than the loading portion 71, the flow channel 62, and the second frame 33. Specifically, the partition plate 74, the flow channel 62, the second frame 33, and the substrate 81 are arranged in this order in the first direction D1. More specifically, the partition plate 74, the flow channel 62, the frame wall 35, and the substrate 81 are arranged in this order in the first direction D1.

[0104] like Fig.11 as well as Fig.12 As shown, the substrate 81 overlaps with the second frame 33 when viewed from the first direction D1. Specifically, the substrate 81 overlaps with the frame wall 35 when viewed from the first direction D1.

[0105] The substrate 81 overlaps with the supply portion 57 when viewed from the first direction D1. In one example, the substrate 81 is not limited to overlapping with the supply portion 57, but also overlaps with the storage body 59. For example, the substrate 81 overlaps with the storage portion 60, the relay member 61, and the flow channel 62 when viewed from the first direction D1.

[0106] like Fig.13 as well as Fig.14As shown, the substrate 81 overlaps with the loading portion 71 when viewed from the first direction D1. Specifically, the substrate 81 overlaps with the partition plate 74 when viewed from the first direction D1. Therefore, the substrate 81 overlaps with the discharge space S1 when viewed from the first direction D1. That is, the substrate 81 overlaps with the flow channel space A3 when viewed from the first direction D1. In one example, the substrate 81 also overlaps with the storage space A2 when viewed from the first direction D1.

[0107] The substrate 81 generates heat. Since the substrate 81 is mounted on the frame, the heat of the substrate 81 easily spreads to the frame space A1. In particular, the heat of the substrate 81 easily spreads to the supply portion 57. This is because the distance between the substrate 81 and the supply portion 57 is relatively close. When the heat spreads to the supply portion 57, the liquid may be heated. In this case, there is a possibility that the recording portion 49 cannot eject the liquid normally.

[0108] The heat of the substrate 81 easily spreads to the storage part 60, the relay component 61, the flow channel 62, etc. located in the storage space A2. In particular, since the substrate 81 is arranged along the frame wall 35, the heat of the substrate 81 easily spreads to the flow channel 62 along the frame wall 35. In particular, since the heated air is easily retained above, the heat of the substrate 81 is easily retained in the flow channel space A3. That is, the heat of the substrate 81 easily spreads to the upper part 65. In this regard, the flow channel space A3 is connected to the outside of the shell 15 through the through-hole 23. Thereby, the possibility of the heat of the substrate 81 being retained in the flow channel space A3 can be reduced. Therefore, the possibility of the supply part 57 being heated can be reduced. In addition, in the frame space A1, by flowing through the through-hole 23 and the vent 24, or flowing through the through-hole 23 and the partition 75, the possibility of heat retention can be reduced. In this way, by allowing air to flow through the flow channel space A3 and the frame space A1, the flow channel 62 and the second frame 33 can be cooled. By cooling the second frame 33, heat transfer from the substrate 81 to the flow channel 62 via the second frame 33 can be suppressed. In addition, by cooling the second frame 33, the substrate 81 can be cooled.

[0109] like Figure 3 As shown, the device body 12 has a fan 82. The fan 82 is mounted on the frame portion 31. The fan 82 is mounted on the second frame 33, for example. The fan 82 is located in the flow channel space A3. The fan 82 is arranged in a manner that communicates with the through-port 23. In one example, the fan 82 overlaps with the through-port 23 when viewed from the second direction D2. Thus, by driving the fan 82, air becomes easy to flow in the flow channel space A3.

[0110] The fan 82 is driven in such a manner that air flows out of the housing 15 from the through-port 23. That is, the fan 82 exhausts air from the inside of the housing 15 to the outside of the housing 15. The fan 82 exhausts air from the flow channel space A3 to the outside of the housing 15 through the through-port 23. Thus, air flows into the flow channel space A3 through the vent 24 and the storage space A2. In addition, air flows into the flow channel space A3 through the partition 75. By driving the fan 82, air can also flow into the flow channel space A3 through the gap of the housing 15. In one example, when the fan 82 is driven, air flows from the partition 75 to the through-port 23 in a manner from the recording portion 49 toward the mounting portion 58. In this case, since the recording portion 49 is actively cooled, it is easy for the recording portion 49 to spray liquid normally.

[0111] The fan 82 may also be driven in such a manner that air flows into the housing 15 from the through-port 23. The fan 82 draws air from the outside of the housing 15 into the housing 15. The fan 82 draws air from the outside of the housing 15 into the flow passage space A3 through the through-port 23. Thus, the air flows out of the flow passage space A3 through the vent 24 and the storage space A2. In addition, the air flows out of the flow passage space A3 through the partition 75. By driving the fan 82, the air may also flow out of the flow passage space A3 through the gap of the housing 15.

[0112] Function and effect

[0113] Next, the operation and effects of the above-described embodiment will be described.

[0114] (1) The flow channel 62 overlaps with the discharge space S1 when viewed from the first direction D1. According to the above structure, the housing 15 can be miniaturized in the vertical direction D3 compared to the case where the flow channel 62 is accommodated below the discharge space S1. Therefore, the possibility of the housing 15 being enlarged in the vertical direction D3 can be reduced.

[0115] (2) The recording unit 49 is located below the discharge space S1. Generally, in the housing 15, the space below the discharge space S1 is larger than the space overlapping the discharge space S1 when viewed from the first direction D1. According to the above structure, since the recording unit 49 is located in the larger space, it becomes easier for the recording unit 49 to record an image on the medium M1.

[0116] (3) When viewed from the first direction D1, the center of the mounting portion 58 is located between the first end 63 and the second end 64. According to the above structure, the possibility of the curvature of the flow channel 62 becoming larger can be reduced compared to the case where the center of the mounting portion 58 is not located between the first end 63 and the second end 64 when viewed from the first direction D1.

[0117] (4) The flow channel 62 overlaps the mounting portion 58 when viewed from the first direction D1. According to the above configuration, the flow channel 62 is less likely to bend more than when the flow channel 62 and the mounting portion 58 do not overlap when viewed from the first direction D1.

[0118] (5) The recording unit 49 is configured to be displaced between the recording position P1 and the retreat position P2. According to the above configuration, by positioning the recording unit 49 at the retreat position P2, it becomes easier for the user to approach the recording unit 49.

[0119] (6) The liquid level in the storage portion 60 is located at a lower position than the ejection surface 52. According to the above configuration, the pressure difference between the liquid level in the storage portion 60 and the ejection surface 52 maintains a negative pressure in the recording portion 49. Thus, the recording portion 49 can eject liquid in a stable state.

[0120] (7) The upper portion 65 does not overlap with the loading surface 72A when viewed from the vertical direction D3. According to the above structure, the possibility of interference between the medium M1 loaded on the loading surface 72A and the flow channel 62 can be reduced compared to the case where the upper portion 65 overlaps with the loading surface 72A when viewed from the vertical direction D3.

[0121] (8) The upper portion 65 is located closer in the first direction D1 than the partition plate 74. According to the above configuration, the possibility of interference between the medium M1 loaded on the loading surface 72A and the flow channel 62 can be reduced.

[0122] (9) The head control unit 53 and the connector 54 are located above the head 50 and exposed from the exposure port 25. According to the above structure, the user can approach the head control unit 53 and the connector 54 from the exposure port 25. The head control unit 53 is connected to electric wires, signal wires, etc. The connector 54 is connected to the flow channel 62. The user can remove these components to take out the recording unit 49 from the housing 15. Therefore, the user can easily replace the recording unit 49 from the exposure port 25.

[0123] (10) The through-hole 23 overlaps with the flow channel 62 when viewed from the front on the first side surface 18. The heat of the substrate 81 may reach the flow channel 62 via the second frame 33. In this regard, according to the above-mentioned structure, the possibility of heating the flow channel 62 can be reduced by allowing air to flow into the housing 15 through the through-hole 23 or by allowing air to flow out of the housing 15 through the through-hole 23.

[0124] (11) The uppermost end of the through-port 23 is located above the uppermost end of the substrate 81. The air heated by the substrate 81 tends to flow upward. Therefore, according to the above structure, the air heated by the substrate 81 flows together with the air flowing into the housing 15 from the through-port 23 or flowing out of the housing 15 from the through-port 23. Thus, the possibility of the air heated by the substrate 81 stagnating in the housing 15 can be reduced. Therefore, the possibility of the flow channel 62 being heated by the substrate 81 can be reduced.

[0125] (12) The partition plate 74 has a partition opening 75 communicating with the exhaust space S1. With the above configuration, air flows through the partition opening 75 and the through opening 23 to flow inside and outside the housing 15, thereby reducing the possibility that the flow path 62 is heated by the substrate 81.

[0126] (13) The recording device 11 includes the fan 82 that causes air to flow out of the housing 15 from the through-port 23. According to the above configuration, the possibility that the flow path 62 is heated by the substrate 81 can be reduced.

[0127] (14) The recording device 11 includes the fan 82 that causes air to flow into the housing 15 from the through-port 23. According to the above configuration, the possibility that the flow path 62 is heated by the substrate 81 can be reduced.

[0128] (15) A portion of the flow path 62 is surrounded by the reading section 13, the second frame 33, and the partition plate 74. According to the above configuration, a portion of the flow path 62 is protected by the reading section 13, the second frame 33, and the partition plate 74.

[0129] (16) Ventilation port 24 is located below through-port 23 on first side surface 18. With the above configuration, air flows through through-port 23 and ventilation port 24 to flow inside and outside housing 15, thereby reducing the possibility that flow path 62 may be heated by substrate 81.

[0130] (17) The uppermost end of the through-hole 23 is located above the uppermost end of the substrate 81. The lowermost end of the vent 24 is located below the lowermost end of the substrate 81. According to the above structure, the air flowing from the through-hole 23 toward the vent 24 or the air flowing from the vent 24 toward the through-hole 23 will spread over the entire length of the substrate 81. Therefore, the air can easily cool the entire substrate 81. Therefore, the possibility of the flow channel 62 being heated by the substrate 81 can be reduced.

[0131] Change Example

[0132] The above-mentioned embodiment can be modified as follows: The above-mentioned embodiment and the following modified examples can be implemented in combination with each other within the scope of no technical contradiction.

[0133] The loading portion 71 may be formed integrally with the housing 15. For example, the housing 15 may include a loading plate 72, an alignment plate 73, and a partition plate 74. The housing 15 defines the discharge space S1 by the loading plate 72, the alignment plate 73, and the partition plate 74.

[0134] The liquid ejected by the recording unit 49 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.

[0135] Technical Thought

[0136] Hereinafter, the technical ideas and effects grasped from the above-mentioned embodiments and modified examples will be described.

[0137] (A) The recording device comprises: a recording portion extending in one direction and capable of spraying liquid all at once across the entire width of a medium; a mounting portion mounted with a storage body for storing liquid; a flow channel connected to the recording portion and the mounting portion; a housing for storing the recording portion, the mounting portion, and the flow channel, the housing defining a discharge space for discharging the medium recorded by the recording portion, the discharge space being a space outside the housing, and the flow channel overlapping the discharge space when viewed from the one direction. According to the above structure, the housing can be miniaturized in the vertical direction compared to a case where the flow channel is accommodated below the discharge space. Therefore, the possibility of the housing being enlarged in the vertical direction can be reduced.

[0138] (B) In the above-mentioned recording device, the recording unit may be located below the discharge space. Generally, in the housing, the space below the discharge space is larger than the space overlapping the discharge space when viewed from one direction. According to the above-mentioned structure, since the recording unit is located in a larger space, it becomes easier for the recording unit to record an image on the medium.

[0139] (C) In the recording device, the flow channel may have a first end and a second end, the first end is connected to the mounting portion, the second end is connected to the recording portion, and the center of the mounting portion is located between the first end and the second end when viewed from the one direction. According to the above structure, the possibility of the flow channel being greatly curved can be reduced compared to a case where the center of the mounting portion is not located between the first end and the second end when viewed from the one direction.

[0140] (D) In ​​the recording device, the flow channel may overlap with the mounting portion when viewed from the one direction. According to the above structure, the possibility of the flow channel being bent more greatly can be reduced compared to a case where the flow channel and the mounting portion do not overlap when viewed from the one direction.

[0141] (E) In the above recording device, it is also possible to provide a support portion, the support portion being opposite to the recording portion, the support portion supporting the medium, and the recording portion being configured to move to a recording position for ejecting liquid to the medium supported by the support portion and to a retreat position further away from the support portion than the recording position. According to the above configuration, by placing the recording portion at the retreat position, it becomes easier for a user to approach the recording portion.

[0142] (F) In the above-mentioned recording device, the recording unit may include a discharge surface from which liquid is discharged, and the mounting unit may include a storage unit for storing the liquid supplied from the storage body, wherein the storage unit stores the liquid in such a manner that the liquid level is located at a lower position than the discharge surface. According to the above-mentioned structure, the pressure difference between the liquid level in the storage unit and the discharge surface can maintain the recording unit at a negative pressure. Thus, the recording unit can discharge the liquid in a stable state.

[0143] (G) The recording device may also be provided with a loading portion, the loading portion being mounted on the housing and loading the medium discharged into the discharge space, the loading portion having a loading surface for receiving the medium, the flow channel having an upper portion located above the loading surface, the upper portion not overlapping the loading surface when viewed from a vertical direction. According to the above configuration, the possibility of interference between the medium loaded on the loading surface and the flow channel can be reduced compared to a case where the upper portion overlaps the loading surface when viewed from a vertical direction.

[0144] (H) In the above recording device, the loading section may include a partition plate extending upward from the loading surface, the partition plate extending in a direction perpendicular to the one direction and in a vertical direction, the discharge space being located in a direction opposite to the one direction relative to the partition plate, and the upper portion being located in a direction relative to the partition plate. According to the above structure, the possibility of interference between the medium loaded on the loading surface and the flow channel can be reduced.

[0145] (I) In the above-mentioned recording device, it can also be set that an exposure port for exposing the interior is opened on the shell, and the loading part is constructed to be displaced between an open state in which the exposure port is exposed and a closed state in which the exposure port is closed, and the recording part has: a head having a nozzle in its opening; a head control part that controls the head; a connector to which the flow channel is connected, and the head control part and the connector are located above the head and exposed from the exposure port. According to the above-mentioned structure, the user can approach the head control part and the connector from the exposure port. Electric wires, signal lines, etc. are connected to the head control part. The flow channel is connected to the connector. The user can remove these components to remove the recording part from the shell. Therefore, the user can easily replace the recording part from the exposure port.

[0146] (J) The recording device may also be configured to include: a first frame that supports the recording unit; a second frame that supports the recording unit; a substrate that is mounted on the second frame, the substrate overlapping the second frame when viewed from the one direction, the partition plate, the flow channel, the second frame, and the substrate being arranged in this order in the one direction, the shell having a surface that extends in the one direction and a vertical direction, a through hole that allows the inside of the shell to communicate with the outside of the shell being opened on the one surface, and the through hole overlapping the flow channel when the one surface is viewed from the front. The heat of the substrate may spread to the flow channel via the second frame. In this regard, according to the above structure, the possibility of the flow channel being heated can be reduced by allowing air to flow into the shell through the through hole, or allowing air to flow out of the shell through the through hole.

[0147] (K) In the above-mentioned recording device, it can also be set that the uppermost end of the through-hole is located at a position above the uppermost end of the substrate. The air heated by passing through the substrate tends to flow upward. Therefore, according to the above-mentioned structure, the air heated by passing through the substrate will flow together with the air flowing into the shell from the through-hole or flowing out of the shell from the through-hole. Thereby, the possibility of the air heated by passing through the substrate stagnating in the shell can be reduced. Therefore, the possibility of the flow channel being heated by the substrate can be reduced.

[0148] (L) In the recording device, the partition plate may have a partition opening communicating with the exhaust space. According to the above structure, air flows inside and outside the housing through the partition opening and the through opening, thereby reducing the possibility of the flow channel being heated by the substrate.

[0149] (M) The recording device may include a fan that causes air to flow out of the housing from the through-hole. According to the above configuration, the possibility that the flow channel is heated by the substrate can be reduced.

[0150] (N) The recording device may include a fan that causes air to flow into the housing from the through-hole. According to the above configuration, the possibility that the flow channel is heated by the substrate can be reduced.

[0151] (O) The recording device may also include a reading unit, the reading unit being supported by the first frame and the second frame and configured to read an image of a manuscript, and a portion of the flow path being surrounded by the reading unit, the second frame, and the partition plate. According to the above configuration, a portion of the flow path is protected by the reading unit, the second frame, and the partition plate.

[0152] (P) In the above recording device, a vent may be opened on one surface, and the vent is located below the through hole on the one surface. According to the above structure, air flows inside and outside the housing through the through hole and the vent, thereby reducing the possibility of the flow channel being heated by the substrate.

[0153] (Q) In the above-mentioned recording device, the uppermost end of the through-hole may be located above the uppermost end of the substrate, and the lowermost end of the vent may be located below the lowermost end of the substrate. According to the above-mentioned structure, the air flowing from the through-hole toward the vent or the air flowing from the vent toward the through-hole will spread over the entire length of the substrate. Therefore, the air can easily cool the entire substrate. Therefore, the possibility of the flow channel being heated by the substrate can be reduced.
