A recording apparatus includes: a recording unit that records an image on a medium by ejecting a liquid onto the medium; a supply unit (67) that supplies a liquid to the recording unit; a substrate unit; and a frame on which the substrate unit is mounted, the frame being positioned between the supply unit and the substrate unit, and the substrate unit being mounted on the frame so as to define a flow space in which air flows between the substrate unit and the frame.

Description

Technical Field

[0001] The present invention relates to a recording device. Background Art

[0002] Patent Document 1 describes a recording device including a recording unit that records an image on a medium by ejecting liquid, a supply unit that supplies liquid to the recording unit, and a substrate unit. For example, the substrate unit includes a control substrate, a power supply substrate, and the like.

[0003] In such a recording device, there is a possibility that the heat of the substrate unit will spread to the supply unit. When the supply unit is heated by the substrate unit, the liquid will reach a high temperature. In this case, the viscosity of the liquid will change or bubbles will be generated in the liquid, so there is a possibility that the recording unit will not be able to eject the liquid normally.

[0036] 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.

[0037] Recording device

[0038] 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 other functions in addition to the function of recording an image on a medium M1.

[0039] The recording device 11 may also include a processing unit 13. The processing unit 13 is configured to process the medium M1 that has been recorded by the device body 12. The processing unit 13 performs, for example, stapling processing, punching processing, etc. on the recorded medium M1. The processing unit 13 is mounted on the device body 12. The processing unit 13 is mounted at the upper part of the device body 12. The processing unit 13 may hold the processed medium M1 or discharge it. The recording device 11 may also include a discharge tray that receives the processed medium M1.

[0040] The recording device 11 may also include a reading unit 14. The reading unit 14 is configured to read an image recorded on a manuscript. The reading unit 14 is a scanner. The reading unit 14 reads images sequentially by automatically feeding the placed manuscript. The reading unit 14 is mounted on the device body 12. The reading unit 14 is mounted at the upper part of the device body 12. The reading unit 14 is located above the processing unit 13. The reading unit 14 overlaps with the device body 12 when viewed from the vertical direction D3.

[0041] The recording device 11 includes an operation unit 15. The operation unit 15 is an interface for a user to operate the recording device 11. The operation unit 15 is, for example, a touch panel. The operation unit 15 may also include buttons, levers, switches, etc. The operation unit 15 is located in front of the device body 12, the processing unit 13, and the reading unit 14.

[0042] Device body

[0043] like Figure 2 as well as Figure 3 As shown, the device body 12 has a shell 16. The shell 16 accommodates various structures of the device body 12. The shell 16 is in the shape of a rectangular parallelepiped. The shell 16 has depth, width, and height. The depth of the shell 16 is the length of the shell 16 in the first direction D1. The width of the shell 16 is the length of the shell 16 in the second direction D2. The height of the shell 16 is the length of the shell 16 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 of the shell 16 toward the depth. The second direction D2 is a direction different from the vertical direction D3. The second direction D2 is a direction from left to right when the shell 16 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.

[0044] The housing 16 has a plurality of surfaces. The housing 16 has a front surface 17, a rear surface 18, and two side surfaces. Specifically, the housing 16 has a front surface 17, a rear surface 18, a first side surface 19, and a second side surface 20. The front surface 17 faces a direction opposite to the first direction D1. In one example, the front surface 17 faces the same direction as the operating unit 15. The front surface 17 is a surface facing a user who operates the recording device 11. The rear surface 18 is a surface opposite to the front surface 17. The rear surface 18 faces the first direction D1. The front surface 17 and the rear surface 18 extend in the second direction D2 and the vertical direction D3. The first side surface 19 faces a direction opposite to the second direction D2. The first side surface 19 faces a direction different from the front surface 17, the rear surface 18, and the second side surface 20. The second side surface 20 faces a direction opposite to the first side surface 19. The second side surface 20 faces the second direction D2. The first side surface 19 and the second side surface 20 extend in the first direction D1 and the vertical direction D3.

[0045] The housing 16 may also be formed with one or more through openings 21. The through openings 21 are opened on one surface of the housing 16. In one example, the through openings 21 are opened on the rear surface 18. The through openings 21 may also be formed as Figure 3 As shown by the dotted line in FIG. 2 , the first side surface 19 is opened. The inside and outside of the housing 16 are communicated through the through-hole 21. Through the through-hole 21, air flows into the housing 16 from the outside, or flows out from the inside.

[0046] The housing 16 may also have more than one cover. In one example, the housing 16 has a protective cover 22. The protective cover 22 is a cover for protecting a substrate unit described later. In one example, the protective cover 22 protects a first substrate unit 83 described later. The protective cover 22, for example, constitutes a portion of the rear surface 18 and the first side surface 19.

[0047] The protective cover 22 is configured to be openable and closable. By opening the protective cover 22, the inside of the housing 16 is exposed. By opening the protective cover 22, the substrate unit is exposed. The protective cover 22 may also be provided with a through hole 21. In this case, air flows from the outside of the housing 16 into the protective cover 22 through the through hole 21, or air flows from the inside of the protective cover 22 to the outside of the housing 16.

[0048] The housing 16 may also have a storage cover 23. The storage cover 23 is a cover for protecting the storage section 76 described later. In one example, the storage cover 23 constitutes the front surface 17. The storage cover 23 is constructed in a manner that can be opened and closed. By opening the storage cover 23, the inside of the housing 16 is exposed. In detail, by opening the storage cover 23, the storage section 76 is exposed.

[0049] like Figure 4 As shown, more than one shell opening 24 may be formed on the shell 16. In one example, two shell openings 24 are formed on the protective cover 22. The two shell openings 24 are arranged in the first direction D1. The shell opening 24 exposes the inside of the shell 16. In one example, the shell opening 24 exposes the inside of the protective cover 22. In detail, the shell opening 24 exposes the handle portion 38 located in the protective cover 22. The handle portion 38 will be described later. The shell opening 24 allows the inside and outside of the shell 16 to communicate. The air flows through the shell opening 24 across the inside and outside of the shell 16. Through the shell opening 24, air flows into the shell 16 from the outside of the shell 16, or air flows out from the inside of the shell 16 to the outside of the shell 16. In detail, through the shell opening 24, air flows into the protective cover 22 from the outside of the shell 16, or air flows out from the inside of the protective cover 22 to the outside of the shell 16.

[0050] like Figure 5 as well as Figure 6 As shown, the device body 12 has a frame portion 26. The frame portion 26 is accommodated in the housing 16. The frame portion 26 supports the processing portion 13. The frame portion 26 supports the reading portion 14. The frame portion 26 supports the operating portion 15. The frame portion 26 supports the housing 16. The frame portion 26 defines a frame space A1. The frame space A1 is a space surrounded by the frame portion 26. That is, the frame space A1 is a space within the frame portion 26. The frame space A1 is a space within the housing 16. Various structures provided in the device body 12 are located in the frame space A1. The frame portion 26 supports various structures accommodated in the housing 16.

[0051] The frame portion 26 has more than one frame. In one example, the frame portion 26 has a first frame 27, a second frame 28, and a third frame 29. The first frame 27, the second frame 28, and the third frame 29 define the frame space A1. The frame is made of metal, for example. Thus, the rigidity of the device body 12 can be ensured.

[0052] The first frame 27 is mounted on the second frame 28 and the third frame 29. The first frame 27 connects the second frame 28 and the third frame 29. The first frame 27 is located at the side of the device body 12. The first frame 27 is, for example, a side frame. The second frame 28 and the third frame 29 are arranged in one direction. In one example, the second frame 28 and the third frame 29 are arranged in the first direction D1. The second frame 28 is located at the rear of the device body 12. The second frame 28 is, for example, a rear frame. The second frame 28 is located closer to the first direction D1 than the first frame 27. The third frame 29 is located at the front of the device body 12. The third frame 29 is, for example, a front frame.

[0053] The frame has opposing surfaces. In one example, the first frame 27 and the second frame 28 each have an opposing surface. Specifically, the first frame 27 has a first opposing surface 30. The second frame 28 has a second opposing surface 31. The opposing surface is a surface that is opposed to the substrate unit. The first opposing surface 30 is a surface that is opposed to the first substrate unit 83. The second opposing surface 31 is a surface that is opposed to the second substrate unit 84 described later.

[0054] The opposing surfaces extend in one direction and in the vertical direction D3. In one example, the first opposing surface 30 extends in the first direction D1 and in the vertical direction D3. The second opposing surface 31 extends in the second direction D2 and in the vertical direction D3. The first opposing surface 30 faces in a direction opposite to the second direction D2. The first opposing surface 30 faces sideways. The first opposing surface 30 extends along the first side surface 19. The second opposing surface 31 faces in the first direction D1. The second opposing surface 31 faces rearward. The second opposing surface 31 extends along the rear surface 18.

[0055] The frame is located between the substrate unit and the supply unit 67 described later. Specifically, the first frame 27 is located between the first substrate unit 83 and the supply unit 67. That is, the first frame 27 is located between the first substrate unit 83 and the supply unit 67 in the second direction D2. The first frame 27 is located between the first substrate unit 83 and the supply unit 67 when viewed from the first direction D1. The second frame 28 is located between the second substrate unit 84 and the supply unit 67. That is, the second frame 28 is located between the second substrate unit 84 and the supply unit 67 in the first direction D1. The second frame 28 is located between the second substrate unit 84 and the supply unit 67 when viewed from the second direction D2.

[0056] The first frame 27 has a plurality of frame parts. In one example, the first frame 27 has a first frame part 32 and a second frame part 33. The first frame part 32 and the second frame part 33 each have an opposing surface. That is, the first frame part 32 and the second frame part 33 each have a first opposing surface 30. The frame part connects the second frame 28 and the third frame 29. The frame part extends in the first direction D1. The frame part is a plate extending in the first direction D1 and the vertical direction D3.

[0057] A plurality of frame components are arranged so as to be separated from each other in the vertical direction D3. The first frame component 32 and the second frame component 33 are arranged so as to be spaced apart in the vertical direction D3. The first frame component 32 and the second frame component 33 are arranged so as to have a gap in the vertical direction D3. The first frame component 32 is located above the second frame component 33. That is, the second frame component 33 is located in the vertical direction D3 compared with the first frame component 32. Therefore, in the frame portion 26, an exposure opening 34 is formed between the first frame component 32 and the second frame component 33. The exposure opening 34 is a gap between the frame components. The exposure opening 34 exposes the inside of the frame portion 26. The exposure opening 34 exposes the frame space A1. Service personnel and users can pass through the exposure opening 34 and approach the frame space A1. In detail, service personnel and users can pass through the exposure opening 34 and approach the supply portion 67.

[0058] The frame components are mounted on the second frame 28 and the third frame 29. In one example, the first frame component 32 is welded to the second frame 28 and the third frame 29. Thus, the rigidity of the frame portion 26 is improved. On the other hand, the second frame component 33 is screwed to the second frame 28 and the third frame 29. Therefore, the second frame component 33 is freely detachable relative to the second frame 28 and the third frame 29. By removing the second frame component 33, it becomes easy for service personnel and users to approach the inside of the frame portion 26 from the exposure port 34. Thus, the maintainability of the device body 12 can be improved. The first frame component 32 can also be screwed to the second frame 28 and the third frame 29, and the second frame component 33 can also be welded to the second frame 28 and the third frame 29. Both the first frame component 32 and the second frame component 33 can be welded to the second frame 28 and the third frame 29, and can also be screwed to the second frame 28 and the third frame 29.

[0059] like Figure 7As shown, a frame opening 35 is formed in the first frame 27. Specifically, a frame opening 35 is formed in the first frame member 32. The frame opening 35 opens on the first opposing surface 30. The frame opening 35 allows the inside and outside of the frame portion 26 to communicate with each other. That is, the frame space A1 communicates with the outside of the frame space A1 through the frame opening 35. Air flows through the frame opening 35 across the inside and outside of the frame portion 26. That is, through the frame opening 35, air flows into the frame portion 26 from the outside of the frame portion 26, or air flows out from the frame portion 26 to the outside of the frame portion 26. In addition, the inside of the frame portion 26 communicates with the outside of the housing 16 through the through opening 21, the housing opening 24, and the frame opening 35. That is, through the through opening 21, the housing opening 24, and the frame opening 35, air flows into the frame portion 26 from the outside of the housing 16, or air flows out from the frame portion 26 to the outside of the housing 16.

[0060] like Figure 5 as well as Figure 6 As shown, the frame portion 26 has a support frame 36. The support frame 36 is a frame that supports the substrate unit. In detail, the support frame 36 supports the first substrate unit 83. The support frame 36 supports the first substrate unit 83 from below. The support frame 36 bears the load of the first substrate unit 83. The support frame 36 has a support surface 37. The support surface 37 is a surface that contacts the first substrate unit 83. The support surface 37 faces upward.

[0061] The support frame 36 connects the second frame 28 and the third frame 29. The support frame 36 is mounted on the second frame 28 and the third frame 29. The support frame 36 is located below the first frame 27. The support frame 36 is located outside the frame space A1. The support frame 36 is protected by the protective cover 22.

[0062] like Figure 4 as well as Figure 6 As shown, the frame portion 26 has more than one handle portion 38. In one example, the frame portion 26 has two handle portions 38. The two handle portions 38 are arranged in the first direction D1. The handle portion 38 is mounted on the support frame 36. The handle portion 38 is located at the lower portion of the support frame 36. The handle portion 38 has a recess that is recessed toward the inside of the housing 16. The recess is recessed toward the top of the housing 16. The handle portion 38 is arranged in a manner that blocks the housing port 24. Service personnel and users can put their hands on the handle portion 38 when carrying the recording device 11.

[0063] The handle portion 38 is not limited to the structure in which it is mounted on the support frame 36. For example, the handle portion 38 may be provided on the housing 16 such as the protective cover 22. Specifically, the handle portion 38 may be mounted at a position corresponding to the housing opening 24 with respect to the protective cover 22. In such a structure, the housing opening 24 exposes the inside of the housing 16 and the inside of the protective cover 22 via the handle portion 38.

[0064] One or more vents 39 are formed on the handle portion 38. Specifically, the vents 39 are opened on the handle portion 38. The inside and outside of the housing 16 are communicated through the housing port 24 and the vents 39. Air flows inside and outside the housing 16 through the housing port 24 and the vents 39. Air flows into the housing 16 from outside the housing 16, or air flows out from inside the housing 16 to outside the housing 16 through the housing port 24 and the vents 39. The vents 39 are not limited to opening on the handle portion 38, but may also be opened on the rear surface 18.

[0065] like Figure 8 As shown, one or more continuous openings 40 are formed on the support frame 36. In one example, a plurality of continuous openings 40 are formed on the support frame 36. The plurality of continuous openings 40 are arranged, for example, in the first direction D1. The continuous openings 40 open on the support surface 37. The continuous openings 40 communicate with the vents 39. Air flows through the continuous openings 40 and the vents 39 to cross the inside and outside of the housing 16.

[0066] like Fig. 9 As shown, the frame portion 26 has a mounting frame 41. The mounting frame 41 is mounted on the first frame 27. In detail, the mounting frame 41 is mounted on the first frame member 32. The mounting frame 41 is mounted on the substrate unit. In detail, the mounting frame 41 is mounted on the first substrate unit 83. Therefore, the first substrate unit 83 is mounted on the first frame 27 via the mounting frame 41.

[0067] like Fig.10 as well as Fig.11As shown, the frame portion 26 may also have a shielding plate 42. The shielding plate 42 is mounted on the frame. In detail, the shielding plate 42 is mounted on the first frame 27. The shielding plate 42 is mounted on the first frame part 32 and the second frame part 33. The shielding plate 42 is mounted in a manner to cover the gap between the first frame part 32 and the second frame part 33. That is, the shielding plate 42 is mounted in a manner to cover the exposure opening 34. The shielding plate 42 is mounted on the first opposing surface 30. The shielding plate 42 is freely removable relative to the first frame 27. In one example, the shielding plate 42 is screwed to the first frame 27. By removing the shielding plate 42, the exposure opening 34 is exposed. Since the shielding plate 42 is screwed to the first frame 27, it can be removed from the second frame 28 and the third frame 29 together with the second frame part 33.

[0068] The shielding plate 42 is located between the substrate unit and the supply portion 67. Specifically, the shielding plate 42 is located between the first substrate unit 83 and the supply portion 67. The shielding plate 42 demarcates the frame space A1 and the outside of the frame space A1 within the housing 16. The shielding plate 42 overlaps with the first substrate unit 83 when the first opposing surface 30 is viewed from the front, that is, when viewed from the second direction D2. The shielding plate 42 overlaps with the supply portion 67 when viewed from the second direction D2. In one example, the shielding plate 42 also overlaps with the storage body 69 described later when viewed from the second direction D2.

[0069] The shielding plate 42 shields the heat of the substrate unit. The shielding plate 42 shields the heat of the first substrate unit 83. Therefore, the shielding plate 42 is preferably made of a material with a low thermal conductivity. In one example, the shielding plate 42 is made of a resin material. In this case, the degree of freedom for the shape of the shielding plate 42 will be increased compared to the case where the shielding plate 42 is made of metal.

[0070] The shielding plate 42 may also be formed by a frame member. The shielding plate 42 may be formed by the first frame member 32 or the second frame member 33. In this case, the first frame member 32 and the second frame member 33 are mounted on the second frame 28 and the third frame 29 without forming the exposure opening 34. In this case, the shielding plate 42 is made of metal.

[0071] like Fig.10 , Fig.11 as well as Fig.12As shown, the shielding plate 42 has a plate portion 43. The plate portion 43 extends in the first direction D1 and the vertical direction D3. The plate portion 43 is mounted on the first frame 27. The plate portion 43 has a shielding surface 44. The shielding surface 44 is a surface facing the substrate unit. In detail, the shielding surface 44 faces the first substrate unit 83. The shielding surface 44 faces the direction opposite to the second direction D2.

[0072] The shielding plate 42 may also have more than one dividing rib 45. In one example, the shielding plate 42 has two dividing ribs 45. The dividing rib 45 extends from the plate portion 43. The dividing rib 45 extends vertically from the shielding surface 44. That is, the dividing rib 45 extends from the plate portion 43 in the opposite direction of the second direction D2.

[0073] The dividing rib 45 extends on a portion of the shielding surface 44 that is opposite to the first substrate unit 83. In one example, the dividing rib 45 extends along the edge of the first substrate unit 83 when viewed from the second direction D2. The dividing rib 45 divides a flow space described later and an outside of the flow space within the housing 16. Specifically, the dividing rib 45 divides a first flow space S1 described later and an outside of the first flow space S1 within the housing 16. The dividing rib 45 guides the air flowing in the first flow space S1.

[0074] Two flow ports are formed on the shielding plate 42. Specifically, a first flow port 46 and a second flow port 47 are formed on the shielding plate 42. The flow port is an opening for air to enter and exit the flow space. The flow port is formed by the plate portion 43 and the two dividing ribs 45. The first flow port 46 is located closer to the vertical direction D3 than the second flow port 47. The first flow port 46 faces the vertical direction D3. The second flow port 47 faces the first direction D1. On the shielding plate 42, the air flows from the first flow port 46 to the second flow port 47, or the air flows from the second flow port 47 to the first flow port 46 through the two dividing ribs 45.

[0075] like Fig.13 As shown, the device body 12 has a storage section 51. The storage section 51 is configured to store the medium M1. In the storage section 51, a plurality of mediums M1 are stored, for example, in a stacked state. The storage section 51 is installed in the housing 16. The storage section 51 is located at the lower part of the housing 16. In one example, the storage section 51 is configured to be insertable and removable relative to the housing 16. The storage section 51 is, for example, a box. The storage section 51 is, for example, insertable and removable relative to the front surface 17. The user can replenish the medium M1 to the storage section 51 by pulling out the storage section 51 from the housing 16. The storage section 51 is not limited to a box, and can also be a tray.

[0076] The device body 12 has a conveying passage 52. The conveying passage 52 is a path for conveying the medium M1. The conveying passage 52 extends inside the housing 16. The conveying passage 52 extends from the inside of the housing 16 toward the outside of the housing 16. Specifically, the conveying passage 52 extends from the storage portion 51 toward the processing portion 13. The medium M1 is recorded with an image while being conveyed on the conveying passage 52.

[0077] The device body 12 includes a conveying unit 53. The conveying unit 53 is configured to convey the medium M1. The conveying unit 53 conveys the medium M1 stored in the storage unit 51. The conveying unit 53 conveys the medium M1 along the conveying path 52. The conveying unit 53 includes one or more rollers 54. In one example, the conveying unit 53 includes a plurality of rollers 54. The plurality of rollers 54 are disposed along the conveying path 52. The plurality of rollers 54 convey the medium M1 by rotating each.

[0078] The device body 12 has a support portion 55. The support portion 55 is configured to support the medium M1. The support portion 55 supports the medium M1 transported from the storage portion 51. The support portion 55 supports the medium M1 transported on the transport path 52. In one example, the support portion 55 supports the medium M1 in an inclined posture relative to the horizontal. The support portion 55 supports the medium M1 by adsorbing it. As a result, the posture of the medium M1 is relatively stable. The support portion 55 can also support the medium M1 in a horizontal posture.

[0079] The support portion 55 may also be configured to transport the medium M1. In one example, the support portion 55 includes a conveyor belt 56, a first pulley 57, and a second pulley 58. The conveyor belt 56 is wound around the first pulley 57 and the second pulley 58. The conveyor belt 56 adsorbs the medium M1, for example, by static electricity. Thus, the conveyor belt 56 supports the medium M1. The conveyor belt 56 may also be configured to adsorb the medium M1 by negative pressure generated by suction, for example. The conveyor belt 56 is rotated by rotating the first pulley 57 and the second pulley 58. As a result, the medium M1 supported on the conveyor belt 56 is transported. The conveyor belt 56 transports the medium M1, for example, diagonally upward. The support portion 55 may also be only a support table.

[0080] The device body 12 includes a recording unit 59. The recording unit 59 is configured to record an image on the medium M1. The recording unit 59 records an image on the medium M1 by ejecting liquid onto the medium M1. The recording unit 59 faces the support unit 55. The recording unit 59 records an image on the medium M1 supported by the support unit 55.

[0081] The recording unit 59 extends in one direction. Specifically, the recording unit 59 extends in the first direction D1. The recording unit 59 includes a line head capable of ejecting liquid all at once across the entire width of the medium M1. The recording unit 59 includes a head 60. The head 60 includes an ejection surface 62 opened by one or more nozzles 61. The head 60 ejects liquid from the nozzles 61. The ejection surface 62 is opposite to the medium M1. The ejection surface 62 is opposite to the support portion 55.

[0082] The recording unit 59 includes a head control unit 63. The head control unit 63 is configured to control the head 60. The head control unit 63 controls the ejection of the liquid by controlling the head 60. The head control unit 63 is located on the upper surface of the head 60. The upper surface of the head 60 is the surface opposite to the ejection surface 62 in the head 60. The head control unit 63 is connected to the substrate unit. The head control unit 63 is connected to the substrate unit, for example, by an electric wire, a signal line, or the like.

[0083] The head control unit 63 may also be composed of one or more processors that perform various processes according to a computer program. The head control unit 63 may also be composed of one or more dedicated hardware circuits such as an ASIC (Application Specific Integrated Circuit) that performs at least a portion of the various processes. The head control unit 63 may also be composed of a circuit that includes 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 performs processing. The memory, i.e., the computer-readable medium, includes all general or dedicated readable media that can be accessed by a computer.

[0084] The recording unit 59 has a joint 64. The joint 64 is connected to the supply unit 67. Liquid is supplied to the head 60 through the joint 64. The joint 64 is located above the head 60. In one example, the joint 64 is located on the side of the head 60. Specifically, the joint 64 is located on the side facing upward among the multiple side surfaces of the head 60.

[0085] The recording unit 59 is configured to move between the recording position P1 and the retreat position P2. The recording unit 59 is displaced between the recording position P1 and the retreat position P2 by moving in a direction perpendicular to the ejection surface 62. The recording unit 59 is displaced by a mechanism such as a rack and pinion, a ball screw, etc.

[0086] The recording position P1 is the position at which the recording unit 59 records on the medium M1. That is, the recording position P1 is the position at which an image is recorded on the medium M1 supported by the support unit 55. The recording position P1 is determined by Fig.13 The solid line in FIG. 5 shows the position of the recording section 59 . At the recording position P1 , the recording section 59 is close to the support section 55 .

[0087] The retreat position P2 is a position when the recording unit 59 retreats from the support unit 55. That is, the retreat position P2 is a position farther from the medium M1 supported by the support unit 55 than the recording position P1. Therefore, the distance between the recording unit 59 at the retreat position P2 and the support unit 55 is greater than the distance between the recording unit 59 at the recording position P1 and the support unit 55. The retreat position P2 is determined by Fig.13 The position of the recording section 59 is indicated by the double-dashed line in FIG.

[0088] The recording unit 59 overlaps with the support unit 55 when viewed from the second direction D2. Specifically, when viewed from the second direction D2, the head 60 overlaps with the conveyor belt 56. In one example, when viewed from the second direction D2, the head 60 at the recording position P1 overlaps with the conveyor belt 56. When viewed from the second direction D2, the head 60 at the retreat position P2 also overlaps with the conveyor belt 56.

[0089] The device body 12 has a maintenance unit 65. The maintenance unit 65 is configured to perform maintenance on the recording unit 59. The maintenance unit 65 performs maintenance on the head 60. Specifically, the maintenance unit 65 performs maintenance on the head 60 by flushing, capping, cleaning, and the like. Flushing is the action of the head 60 appropriately ejecting liquid from the nozzle 61. By flushing, clogging of the nozzle 61 is suppressed. The maintenance unit 65 receives the liquid generated by flushing. Capping is the action of moisturizing the nozzle 61. By capping, clogging of the nozzle 61 is suppressed. The maintenance unit 65 forms a space communicating with the nozzle 61 by contacting with the head 60. Cleaning is the action of discharging liquid from the nozzle 61. By cleaning, foreign matter is discharged from the head 60 together with the liquid. The maintenance unit 65 discharges the liquid from the nozzle 61 by suction.

[0090] The maintenance unit 65 is configured to be displaceable. The maintenance unit 65 is displaced, for example, by a rack and pinion, a ball screw, etc. When the maintenance unit 65 is performing maintenance on the recording unit 59, the maintenance unit 65 is located at the maintenance position. The maintenance position is a position between the support unit 55 and the recording unit 59. In the maintenance position, the maintenance unit 65 is opposite to the ejection surface 62. When the maintenance unit 59 is not being maintained, the maintenance unit 65 is located at the standby position. The standby position is a position retreated from between the support unit 55 and the recording unit 59. Fig.13 The maintenance section 65 is shown in a standby position.

[0091] A waste liquid tank 66 may also be installed on the device body 12. The waste liquid tank 66 is a tank for storing liquid discharged due to maintenance. The waste liquid tank 66 is connected to the maintenance unit 65. The waste liquid tank 66 stores liquid received by the maintenance unit 65 due to flushing, cleaning, etc. In one example, the waste liquid tank 66 is a replaceable tank.

[0092] The waste liquid tank 66 overlaps with the maintenance unit 65 when viewed from the second direction D2. Specifically, the waste liquid tank 66 overlaps with the maintenance unit 65 at the standby position when viewed from the second direction D2. The waste liquid tank 66 may overlap with the maintenance unit 65 at the maintenance position when viewed from the second direction D2. The waste liquid tank 66 is mounted on the device body 12 in such a manner that the waste liquid tank 66 overlaps with the maintenance unit 65 when viewed from the second direction D2.

[0093] The device body 12 includes a supply unit 67. The supply unit 67 is configured to supply liquid to the recording unit 59. The supply unit 67 is connected to the recording unit 59. The supply unit 57 is connected to the joint 54. The supply unit 67 is located between the first frame 27 and the conveying unit 53 when viewed from the first direction D1. That is, in the first direction D1, the distance between the first frame 27 and the supply unit 67 is smaller than the distance between the first frame 27 and the conveying unit 53. Therefore, the conveying unit 53 is close to the second side surface 20, and the supply unit 67 is close to the first side surface 19. Therefore, the supply unit 67 is close to the first substrate unit 83.

[0094] The supply unit 67 has a mounting unit 68. The mounting unit 68 is configured to mount one or more storage bodies 69. In one example, four storage bodies 69 are mounted on the mounting unit 68. Specifically, four storage bodies 69 are mounted on the mounting unit 68 in a state of being arranged in the second direction D2. The storage body 69 is configured to store liquid. The storage body 69 is, for example, an ink cartridge. The four storage bodies 69 store different types of liquids, respectively. The four storage bodies 69 store liquids of different colors, respectively.

[0095] The storage body 69 overlaps with the recording unit 59 when viewed from the second direction D2. Specifically, the storage body 69 overlaps with the head 60 located at the recording position P1 when viewed from the second direction D2. The storage body 69 also overlaps with the head 60 located at the retreat position P2 when viewed from the second direction D2. The storage body 69 is mounted on the mounting portion 68 so that the storage body 69 overlaps with the recording unit 59 when viewed from the second direction D2.

[0096] The storage body 69 overlaps with the support portion 55 when viewed from the second direction D2. That is, the storage body 69 is attached to the attachment portion 68 so that the storage body 69 overlaps with the support portion 55 when viewed from the second direction D2.

[0097] The mounting portion 68 has a storage portion 70. The storage portion 70 is configured to mount the storage body 69. The storage portion 70 is configured to store the liquid supplied from the storage body 69. The storage portion 70 separately stores a plurality of liquids supplied from the plurality of storage bodies 69. The storage portion 70 is located below the storage body 69.

[0098] The storage part 70 stores the liquid in such a manner that the liquid level is located at the reference position L1. The storage part 70 receives the liquid from the storage body 69 so that the liquid level is maintained at the reference position L1. In one example, the inside of the storage part 70 is opened to the atmosphere. The liquid is automatically supplied from the storage body 69 to the storage part 70 by the atmospheric pressure. For the storage part 70, when the liquid level is lower than the reference position L1, the liquid is supplied from the storage body 69 to the storage part 70. When the liquid level reaches the reference position L1, the supply of the liquid from the storage body 69 to the storage part 70 is stopped.

[0099] The reference position L1 is located below the head 60. Specifically, the reference position L1 is located below the ejection surface 62. The storage portion 70 supplies liquid according to the water level difference with the recording portion 59. Therefore, since the reference position L1 is located below the ejection surface 62, negative pressure is generated in the head 60. As a result, a meniscus can be formed in the nozzle 61. Therefore, the head 60 can appropriately eject liquid.

[0100] The mounting portion 68 has a relay component 71. The relay component 71 is a component that relays the storage portion 70 and the recording portion 59. The relay component 71 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 71 is connected to the storage portion 70. The liquid stored in the storage portion 70 flows in the relay component 71. The relay component 71 extends below the storage portion 70. The relay component 71 extends in the first direction D1. The relay component 71 extends below the storage portion 70 toward the rear of the storage portion 70.

[0101] The supply unit 67 has a flow channel 72. Liquid flows in the flow channel 72. The flow channel 72 is a flexible tube. In one example, the flow channel 72 is a multi-tube for flowing multiple liquids. The flow channel 72 can also be composed of multiple tubes that are pulled and aligned. The flow channel 72 is connected to the mounting unit 68 and the recording unit 59. In detail, the flow channel 72 is connected to the relay component 71 and the connector 64.

[0102] The flow channel 72 has a first end 73 and a second end 74. The first end 73 is connected to the mounting portion 68. Specifically, the first end 73 is connected to the relay component 71. The second end 74 is connected to the recording portion 59. Specifically, the second end 74 is connected to the connector 64. Therefore, the distance between the first end 73 and the mounting portion 68 is smaller than the distance between the first end 73 and the recording portion 59. The distance between the second end 74 and the recording portion 59 is smaller than the distance between the second end 74 and the mounting portion 68.

[0103] The first end 73 and the second end 74 are arranged so as to sandwich the center of the mounting portion 68 when viewed from the first direction D1. In one example, the first end 73 is located in the opposite direction of the second direction D2 compared to the center line L2. The center line L2 is an imaginary line that divides the mounting portion 68 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 68 in the second direction D2. The second end 74 is located in the second direction D2 compared to the center line L2. That is, the first end 73 and the second end 74 are arranged so as to sandwich the center line L2 in the second direction D2. As a result, the curvature of the flow channel 72 can be reduced. Assuming that both the first end 73 and the second end 74 are located in the second direction D2 compared to the center line L2, the curvature of the flow channel 72 will become stronger. In this case, there is a possibility that the flow channel 72 is bent into an acute angle. When the flow channel 72 is constituted by a plurality of tubes, the first end 73 and the second end 74 of at least one of the plurality of tubes may be provided so as to sandwich the center line L2.

[0104] The flow channel 72 has an upper portion 75. The upper portion 75 is a portion including the top of the flow channel 72. That is, the upper portion 75 includes a portion located at the vertex of the flow channel 72. The upper portion 75 is a portion located between the first end 73 and the second end 74. The upper portion 75 includes a portion that is curved in a convex manner upward. The upper portion 75 is a portion that overlaps with the storage portion 76 described later when viewed from the first direction D1. The upper portion 75 is located in the flow channel space A3 described later.

[0105] The flow channel 72 overlaps with the mounting portion 68 when viewed from the first direction D1. Specifically, a portion of the flow channel 72 including the first end 73 overlaps with the storage portion 70 when viewed from the first direction D1. The flow channel 72 extends upward from the relay member 71. The flow channel 72 extends straight upward from the rear of the storage portion 70. The flow channel 72 extends upward from the first end 73 toward the second end 74, and then extends in the second direction D2. The flow channel 72 extends from the first end 73 to the second end 74 along the second frame 28. Therefore, the flow channel 72 is close to the second substrate unit 84.

[0106] The flow channel 72 overlaps with the housing body 69 when viewed from the first direction D1. That is, the housing body 69 is mounted on the mounting portion 68 in such a manner that the flow channel 72 overlaps with the housing body 69 when viewed from the first direction D1. In one example, a portion of the flow channel 72 between the first end 73 and the upper portion 75 overlaps with the housing body 69 when viewed from the first direction D1.

[0107] The supply portion 67 overlaps with the waste liquid tank 66 when viewed from the second direction D2. Specifically, the mounting portion 68 overlaps with the waste liquid tank 66 when viewed from the second direction D2. More specifically, the storage portion 70 overlaps with the waste liquid tank 66 when viewed from the second direction D2. That is, the waste liquid tank 66 is mounted on the device body 12 in such a manner that the storage portion 70 overlaps with the waste liquid tank 66.

[0108] The supply portion 67 overlaps with the maintenance portion 65 when viewed from the second direction D2. Specifically, the mounting portion 68 overlaps with the maintenance portion 65 when viewed from the second direction D2. In further detail, the storage portion 70 overlaps with the maintenance portion 65 when viewed from the second direction D2. In one example, the storage portion 70 overlaps with the maintenance portion 65 at the standby position when viewed from the second direction D2. The storage portion 70 may also overlap with the maintenance portion 65 at the maintenance position when viewed from the second direction D2.

[0109] The supply portion 67 may overlap with the recording portion 59 when viewed from the second direction D2. The supply portion 67 may overlap with the recording portion 59 at the recording position P1 or at the retreat position P2 when viewed from the second direction D2. The mounting portion 68 may overlap with the recording portion 59 when viewed from the second direction D2. The storage portion 70 may overlap with the recording portion 59 when viewed from the second direction D2. The storage portion 70 may overlap with the head 60 when viewed from the second direction D2, in a state where the reference position L1 is located below the ejection surface 52.

[0110] like Fig.14As shown, the supply portion 67 overlaps with the shielding plate 42 indicated by the double-dashed line when viewed from the second direction D2. In detail, the mounting portion 68 and the flow channel 72 overlap with the shielding plate 42 when viewed from the second direction D2. In further detail, the storage portion 70 and the flow channel 72 overlap with the shielding plate 42 when viewed from the second direction D2. Although in one example, the relay component 71 does not overlap with the shielding plate 42, it is possible to overlap. In addition, in addition to the supply portion 67, the storage body 69 also overlaps with the shielding plate 42 when viewed from the second direction D2.

[0111] like Fig.13 As shown, the device body 12 has a storage section 76. The storage section 76 is configured to store items. The storage section 76 stores, for example, a user manual of the recording device 11. In one example, the storage section 76 is exposed by opening the storage cover 23. Therefore, the user approaches the storage section 76 from the front surface 17.

[0112] The storage section 76 is stored in the housing 16. The storage section 76 is located at the upper part in the housing 16. The storage section 76 is located above the recording section 59. The storage section 76 is located above the mounting section 68. The storage section 76 overlaps with the processing section 13 when viewed from the vertical direction D3. The storage section 76 is located directly below the processing section 13. The storage section 76 is mounted in the housing 16 in a manner in which the processing section 13 is loaded. The storage section 76 is mounted on the frame section 26. In one example, the storage section 76 is mounted on the second frame 28 and the third frame 29.

[0113] like Fig.15 As shown, the storage section 76 is a component for demarcating the storage space A2. The storage section 76 stores items in the storage space A2. The storage space A2 is a space within the frame space A1. The storage section 76 has a rear plate 77, a top plate 78, a bottom plate 79, a first side plate 80, and a second side plate 81. The storage space A2 is a space surrounded by the rear plate 77, the top plate 78, the bottom plate 79, the first side plate 80, and the second side plate 81.

[0114] The rear plate 77 is a plate located at the rear in the storage section 76. The rear plate 77 extends in the second direction D2 and the vertical direction D3. The top plate 78 is a plate located at the top in the storage section 76. The top plate 78 extends in the first direction D1 and the second direction D2. The top plate 78 supports the processing section 13. The bottom plate 79 is a plate located at the bottom in the storage section 76. The bottom plate 79 extends in the first direction D1 and the second direction D2. The first side plate 80 is a plate located at the left when the device body 12 is observed from the first direction D1. The first side plate 80 extends in the first direction D1 and the vertical direction D3. The second side plate 81 is a plate located at the right when the device body 12 is observed from the first direction D1. The second side plate 81 extends in the first direction D1 and the vertical direction D3.

[0115] The storage portion 76 has a storage opening 82 formed therein. The storage opening 82 is an opening for a user to approach the storage space A2. The storage opening 82 is formed by the rear plate 77, the top plate 78, the bottom plate 79, the first side plate 80, and the second side plate 81.

[0116] like Fig.16 as well as Fig.17 As shown, the storage portion 76 defines the flow channel space A3. In detail, the rear plate 77 and the top plate 78 define the flow channel space A3. The flow channel space A3 is the space within the frame space A1. The flow channel space A3 is the space where the upper portion 75 is located. That is, the portion that is bent in the flow channel 72 is located in the flow channel space A3. The rear plate 77 and the top plate 78 protect the flow channel 72. The flow channel space A3 is defined by the second frame 28. The flow channel space A3 is defined by the storage portion 76 and the second frame 28. The flow channel space A3 is a space sandwiched by the storage portion 76 and the second frame 28. The flow channel space A3 is located between the storage portion 76 and the second frame 28 in the first direction D1. By locating the flow channel 72 in the flow channel space A3, the degree of curvature of the flow channel 72 can be reduced compared to the case where the flow channel 72 is only accommodated in the storage space A4 described later. When the flow channel 72 is accommodated only in the storage space A4, it is considered to enlarge the storage space A4 in order to reduce the curvature of the flow channel 72. In this case, although there is a possibility that the device body 12 is enlarged, the possibility of enlargement of the device body 12 can be reduced by locating the flow channel 72 in the flow channel space A3.

[0117] The flow channel space A3 is communicated with the space outside the frame through the frame opening 35. That is, the flow channel space A3 is communicated with the outside of the frame space A1 through the frame opening 35. Therefore, air flows into the flow channel space A3 from outside the shell 16, or air flows out of the flow channel space A3 to outside the shell 16 through the through opening 21, the shell opening 24, and the frame opening 35. The present invention is not limited to this, and the air may also enter and exit the flow channel space A3 through the gap between the frames, the gap between the frame portion 26 and the shell 16, and the like.

[0118] The storage section 76 defines the storage space A4. In detail, the bottom plate 79 defines the storage space A4. The storage space A4 is a space within the frame space A1. In one example, the storage section 76 divides the frame space A1 into a storage space A2, a flow channel space A3, and a storage space A4. The storage space A4 is a space for storing the recording section 59, the mounting section 68, etc. In one example, the storage space A4 is a space below the storage section 76. The storage space A4 is a space surrounded by the storage section 76, the first frame 27, and the second frame 28. The storage space A4 is connected to the flow channel space A3. Therefore, through the through-port 21, the shell port 24, and the frame port 35, air flows into the storage space A4 from outside the shell 16, or air flows out from the storage space A4 to outside the shell 16. The present invention is not limited thereto, and the air may enter and exit the storage space A4 through gaps between the frames, gaps between the frame portion 26 and the housing 16, and the like.

[0119] like Fig.17 as well as Fig.18 As shown, the device body 12 includes one or more substrate units. Specifically, the device body 12 includes a first substrate unit 83 and a second substrate unit 84. In one example, the first substrate unit 83 is a substrate unit that controls the power supplied to the device body 12. The second substrate unit 84 is a substrate unit that controls the driving of the device body 12.

[0120] The substrate unit is mounted on the frame portion 26. Specifically, the substrate unit is mounted on the frame. In one example, the substrate unit is fixed to the frame so as not to be displaced. The substrate unit may also be mounted to open and close relative to the frame, for example.

[0121] The first substrate unit 83 is mounted on the first frame 27. Specifically, the first substrate unit 83 is mounted on the support frame 36 and the mounting frame 41. The first substrate unit 83 is mounted on the first frame 27 via the support frame 36 and the mounting frame 41. The first substrate unit 83 faces the first opposing surface 30. The first substrate unit 83 is close to the supply portion 67. Specifically, the first substrate unit 83 is close to the storage portion 70, the relay member 71, and the flow path 72.

[0122] like Fig.16 As shown, when viewed from the second direction D2, the first substrate unit 83 indicated by the two-dot chain line overlaps the reservoir 70, the relay member 71, and the flow path 72. When viewed from the second direction D2, the first substrate unit 83 overlaps the storage space A4.

[0123] like Fig.17 as well as Fig.18 As shown, the second substrate unit 84 is mounted on the second frame 28. The second substrate unit 84 faces the second facing surface 31. The second substrate unit 84 is close to the supply portion 67. Specifically, the second substrate unit 84 is close to the storage portion 70, the relay member 71, and the flow channel 72.

[0124] like Fig.17 as well as Fig.19 As shown, when viewed from the first direction D1, the second substrate unit 84 overlaps with the storage portion 70, the relay member 71, and the flow channel 72. When viewed from the first direction D1, the second substrate unit 84 overlaps with the flow channel space A3. Therefore, when viewed from the first direction D1, the second substrate unit 84 overlaps with the upper portion 75. When viewed from the first direction D1, the second substrate unit 84 overlaps with the storage space A4. In addition, Fig.19 In FIG. 8 , the second substrate unit 84 is indicated by a dotted line.

[0125] The substrate unit generates heat. Since the substrate unit is mounted on the frame, the heat of the substrate unit easily spreads to the frame space A1. In particular, the heat of the substrate unit easily spreads to the supply unit 67. This is because the distance between the substrate unit and the supply unit 67 is relatively close. When the heat spreads to the supply unit 67, there is a possibility that the liquid is heated. In this case, there is a possibility that the recording unit 59 cannot eject the liquid normally.

[0126] The heat of the first substrate unit 83 easily spreads to the storage portion 70, the relay component 71, and the flow channel 72 located in the storage space A4. The heat of the second substrate unit 84 easily spreads to the storage portion 70, the relay component 71, and the flow channel 72 located in the storage space A4. Since the second substrate unit 84 is arranged along the second frame 28, the heat of the second substrate unit 84 easily spreads to the flow channel 72 located in the flow channel space A3. In other words, the heat of the second substrate unit 84 easily spreads to the upper portion 75.

[0127] The substrate unit is provided on the frame in such a manner as to define a flow space between the substrate unit and the frame. The substrate unit is installed on the frame in such a manner as to define a flow space between the substrate unit and the frame. The first substrate unit 83 is installed on the first frame 27 in such a manner as to define a first flow space S1 between the substrate unit and the first frame 27. The second substrate unit 84 is installed on the second frame 28 in such a manner as to form a second flow space S2 between the substrate unit and the second frame 28.

[0128] The flow space is a space for air to flow. The flow space is a space inside the shell 16 and outside the frame portion 26. The flow space is a space between the substrate unit and the opposing surface. That is, the first flow space S1 is a space between the first substrate unit 83 and the first opposing surface 30. The second flow space S2 is a space between the second substrate unit 84 and the second opposing surface 31. By allowing air to flow in the flow space, the substrate unit is cooled, and the heat transferred from the substrate unit to the supply portion 67 via the frame portion 26 is reduced. For example, air flows into the flow space from outside the shell 16 through a gap, an opening, etc. in the shell 16, or air flows out of the flow space to outside the shell 16, thereby allowing air to flow in the flow space.

[0129] like Fig.19 As shown, the first flow space S1 is communicated with the vent 39, the continuous port 40 and the first flow port 46. That is, the first flow space S1 is communicated with the outside of the shell 16 through the handle portion 38. Therefore, through the handle portion 38, air flows into the first flow space S1, or air flows out of the first flow space S1. The first flow space S1 is communicated with the second flow port 47 and the through-port 21. Therefore, through the through-port 21, air flows into the first flow space S1, or air flows out of the first flow space S1. At this time, since the dividing ribs 45 guide the air, the air is easy to flow in the first flow space S1. Through the gaps, openings, etc. of the shell 16 including the through-port 21 and the shell port 24, air flows into the second flow space S2 from the outside of the shell 16, or air flows out of the second flow space S2 to the outside of the shell 16.

[0130] like Fig.18 as well as Fig.19As shown, the first substrate unit 83 is mounted on the first frame member 32 and the second frame member 33. The first substrate unit 83 is mounted so as to cover the gap between the first frame member 32 and the second frame member 33. The first substrate unit 83 is mounted so as to straddle the first frame member 32 and the second frame member 33. The first substrate unit 83 is mounted on the first frame member 32 and the second frame member 33 so as to cover the exposure opening 34. The first substrate unit 83 may also be mounted so as to be opened and closed relative to the frame portion 26.

[0131] The first substrate unit 83 is provided in a manner that does not extend from the processing section 13 in the second direction D2. That is, the first substrate unit 83 is located closer to the second direction D2 than the end surface of the processing section 13 when viewed from the first direction D1. The end surface of the processing section 13 is a surface that becomes the top in the opposite direction of the second direction D2. In one example, the first side surface 19 is provided in a manner that is flush with the end surface of the processing section 13. Therefore, the possibility of the lower edge space of the device body 12 becoming larger can be reduced by the first substrate unit 83.

[0132] The first substrate unit 83 is provided so as to overlap with the shielding plate 42 when viewed from the second direction D2. The first substrate unit 83 is opposite to the shielding surface 44. The shielding plate 42 makes it difficult for the heat of the first substrate unit 83 to reach the supply portion 67. In one example, a portion of the first substrate unit 83 overlaps with the shielding plate 42. Preferably, a portion of the first substrate unit 83 with a larger heat generation overlaps with the shielding plate 42.

[0133] like Fig. 20 As shown, the first substrate unit 83 has a power supply housing 85 and a power supply substrate 86. The power supply housing 85 accommodates the power supply substrate 86. The power supply substrate 86 has one or more heating elements 87. The heating element 87 includes an element that generates heat through electricity. The heating element 87 is, for example, a circuit such as a converter or an inverter. The heating element 87 overlaps with the shielding plate 42 when viewed from the second direction D2. As a result, the heat of the heating element 87 is not easy to spread to the supply portion 67. Therefore, the heat of the first substrate unit 83 is effectively shielded by the shielding plate 42. The second substrate unit 84 has a control housing and a control substrate in the same manner as the first substrate unit 83.

[0134] The first substrate unit 83 has one or more exhaust parts 88. In one example, the first substrate unit 83 has two exhaust parts 88. The exhaust part 88 is mounted on the power supply housing 85. The exhaust part 88 is configured to exhaust air from the power supply housing 85. The exhaust part 88 includes, for example, a fan. In one example, the exhaust part 88 exhausts air from the power supply housing 85 in a first direction D1. The air exhausted from the power supply housing 85 passes through a gap, an opening, etc. of the housing 16 and is exhausted to the outside of the housing 16. The exhaust part 88 can suppress the temperature rise of the first substrate unit 83.

[0135] The device body 12 has a duct 90. The duct 90 is mounted on the first frame 27. Specifically, the duct 90 is mounted on the first frame member 32. The duct 90 communicates with the through-port 21. The duct 90 communicates with the frame port 35. The duct 90 communicates with the second flow port 47.

[0136] The duct 90 communicates the flow space with the outside of the shell 16. Specifically, the duct 90 communicates the first flow space S1 with the outside of the shell 16. The duct 90 communicates the first flow space S1 with the outside of the shell 16 via the second flow port 47 and the through port 21. The duct 90 communicates the flow channel space A3 with the outside of the shell 16 via the frame port 35 and the through port 21. The duct 90 communicates the first flow space S1 with the flow channel space A3 via the frame port 35 and the second flow port 47. Therefore, the duct 90 separates the air flowing in from the outside of the shell 16 into the flow channel space A3 and the first flow space S1, or discharges the air flowing through the flow channel space A3 to the outside of the shell 16 after merging the air flowing through the first flow space S1.

[0137] like Fig.21 As shown, a plurality of pipe openings are formed on the pipe 90. In one example, a first pipe opening 91, a second pipe opening 92, and a third pipe opening 93 are opened on the pipe 90. In the pipe 90, the first pipe opening 91, the second pipe opening 92, and the third pipe opening 93 are connected to each other. The first pipe opening 91 opens in the opposite direction of the first direction D1. The second pipe opening 92 opens in the second direction D2. The third pipe opening 93 opens in the first direction D1.

[0138] like Fig.10 as well as Fig.19 As shown, the first duct opening 91 is communicated with the second flow opening 47. The first duct opening 91 is opposite to the second flow opening 47. Therefore, the duct 90 is communicated with the first flow space S1.

[0139] The duct 90 is located at a position overlapping with the flow space when viewed from the first direction D1. Specifically, the duct 90 is located at a position overlapping with the first flow space S1 when viewed from the first direction D1. Thus, the duct 90 becomes easy to communicate with the first flow space S1. That is, the first duct port 91 becomes easy to face the second flow port 47.

[0140] like Figure 7 as well as Fig. 22 As shown, the second duct opening 92 is communicated with the frame opening 35. The second duct opening 92 is opposite to the frame opening 35. Therefore, the duct 90 is communicated with the flow channel space A3.

[0141] like Fig.17 As shown, the duct 90 is arranged side by side with the flow channel space A3 in the second direction D2. The duct 90 is located at a position overlapping with the flow channel space A3 when viewed from the second direction D2. As a result, the duct 90 becomes easy to communicate with the flow channel space A3. That is, the second duct port 92 becomes easy to be opposite to the frame port 35.

[0142] like Figure 3 as well as Fig.18 As shown, the third duct opening 93 is communicated with the through opening 21. The third duct opening 93 is opposite to the through opening 21. Therefore, the duct 90 is communicated with the outside of the housing 16. In the case where the through opening 21 is opened on the first side surface 19, the third duct opening 93 is formed in a manner of opening in the duct 90 in the opposite direction to the second direction D2.

[0143] The uppermost end of the duct 90 is located above the uppermost end of the first substrate unit 83. The air heated by the first substrate unit 83 is likely to be retained above the housing 16. For example, the air heated by the first substrate unit 83 is likely to be retained above the first flow space S1 or in the flow channel space A3. Therefore, the air heated by the first substrate unit 83 is likely to flow together with the air flowing into the housing 16 from the duct 90 or the air flowing out of the housing 16 from the duct 90. As a result, the possibility of the air heated by the first substrate unit 83 being retained in the housing 16 can be reduced.

[0144] The uppermost end of the duct 90 is located above the uppermost end of the second substrate unit 84. The air heated by the second substrate unit 84 is likely to be retained at the upper part of the housing 16. For example, the air heated by the second substrate unit 84 is likely to be retained in the flow channel space A3. Therefore, the air heated by the second substrate unit 84 is likely to flow together with the air flowing into the housing 16 from the duct 90 or the air flowing out of the housing 16 from the duct 90. As a result, the possibility of the air heated by the second substrate unit 84 being retained in the housing 16 can be reduced.

[0145] like Fig.18 As shown, the device body 12 has a fan 95. The fan 95 is mounted on the duct 90. The fan 95 is located in the duct 90. The fan 95 is driven so that the air can easily flow in the flow channel space A3 and the first flow space S1.

[0146] The fan 95 is driven so that air flows out of the duct 90 to the outside of the recording device 11. That is, the fan 95 is driven so that air is exhausted from the inside of the housing 16 to the outside of the housing 16. The fan 95 is driven so that air flowing in from the first duct port 91 and the second duct port 92 is discharged from the third duct port 93. Thus, for the first flow space S1, air flows in through the housing port 24, the vent port 39, the continuous port 40, and the first flow port 46, and air flows out through the second flow port 47, the first duct port 91, the third duct port 93, and the through port 21. For the flow channel space A3, air flows in through the gap, opening, etc. of the housing 16, and air flows out through the frame port 35, the second duct port 92, the third duct port 93, and the through port 21.

[0147] The fan 95 may be driven so that air flows from the duct 90 into the recording device 11. That is, the fan 95 may be driven so that air is sucked from the outside of the housing 16 toward the inside of the housing 16. The fan 95 may be driven so that air flowing in from the third duct port 93 is discharged from the first duct port 91 and the second duct port 92. Thus, for the first flow space S1, air flows in through the through port 21, the third duct port 93, the first duct port 91, and the second flow port 47, and air flows out through the first flow port 46, the continuous port 40, the vent port 39, and the housing port 24. For the flow channel space A3, air flows in through the through port 21, the third duct port 93, the second duct port 92, and the frame port 35, and air flows out through the gap, opening, etc. of the housing 16.

[0148] Function and effect

[0149] Next, the operation and effects of the above-described embodiment will be described.

[0150] (1) The substrate unit is provided in a manner that defines a flow space for air flow between the substrate unit and the frame. The substrate unit is mounted on the frame in a manner that defines a flow space for air flow between the substrate unit and the frame. That is, the first substrate unit 83 is mounted on the first frame 27 in a manner that defines a first flow space S1. The second substrate unit 84 is mounted on the second frame 28 in a manner that defines a second flow space S2. According to the above structure, by making the air flow in the flow space, the heat of the substrate unit becomes less likely to spread to the supply portion 67. As a result, the possibility of the supply portion 67 being heated by the substrate unit can be reduced.

[0151] (2) The housing 16 is provided with a through hole 21 that allows the first flow space S1 to communicate with the outside of the housing 16. According to the above structure, air flows into the first flow space S1 through the through hole 21, or flows out of the first flow space S1 through the through hole 21, so that air can flow easily in the first flow space S1. As a result, the possibility that the supply portion 67 is heated by the first substrate unit 83 can be reduced.

[0152] (3) The shielding plate 42 is attached to the first frame member 32 and the second frame member 33 to cover the exposure opening 34. According to the above structure, the possibility that the heat of the first substrate unit 83 passes through the exposure opening 34 and reaches the supply portion 67 can be reduced.

[0153] (4) The shielding plate 42 is provided between the supply portion 67 and the first substrate unit 83. The shielding plate 42 overlaps the supply portion 67 when the first facing surface 30 is viewed from the front. According to the above structure, the heat from the first substrate unit 83 to the supply portion 67 is effectively shielded by the shielding plate 42.

[0154] (5) The supply unit 67 is located between the first frame 27 and the conveying unit 53 when viewed from the first direction D1. According to the above configuration, the heat of the first substrate unit 83 is less likely to reach the conveying unit 53.

[0155] (6) The duct 90 connects the first flow space S1 and the flow channel space A3. According to the above structure, the first flow space S1 and the flow channel space A3 are connected to the outside of the recording device 11 through the duct 90. As a result, the structure of the recording device 11 becomes simpler than when the first flow space S1 and the flow channel space A3 are connected to the outside of the recording device 11 separately. By air flowing through the first flow space S1 and the flow channel space A3, the possibility of the supply part 67 being heated by the substrate unit can be reduced.

[0156] (7) The duct 90 communicates with the through-port 21. According to the above configuration, the first flow space S1 and the flow path space A3 communicate with the outside of the recording device 11 through the through-port 21 and the duct 90. This reduces the possibility that heat from the substrate unit is retained in the housing 16.

[0157] (8) The through-port 21 opens on the rear surface 18. Normally, the user operates the recording device 11 from the front surface 17. Therefore, according to the above structure, the possibility that the air flowing into the housing 16 through the through-port 21 or the air flowing out of the housing 16 through the through-port 21 will affect the user can be reduced.

[0158] (9) The duct 90 is located at a position overlapping the first flow space S1 when viewed from the first direction D1 and at a position overlapping the flow channel space A3 when viewed from the second direction D2. With the above structure, the duct 90 can easily communicate with the first flow space S1 and the flow channel space A3.

[0159] (10) The flow path space A3 is defined by the second frame 28 and the storage portion 76. According to the above configuration, the flow path 72 can be protected by the second frame 28 and the storage portion 76.

[0160] (11) The processing unit 13 is located above the storage unit 76 and overlaps the storage unit 76 when viewed from the vertical direction D3. According to the above configuration, the processing unit 13 can reduce the possibility that the space below the recording device 11 becomes larger.

[0161] (12) The uppermost end of the duct 90 is located above the uppermost end of the first substrate unit 83 and above the uppermost end of the second substrate unit 84 in the vertical direction D3. The air heated by the substrate unit is likely to be retained at the upper part. Therefore, according to the above structure, the air heated by the substrate unit is likely to flow together with the air flowing into the device from the duct 90 or the air flowing out of the device from the duct 90. As a result, the possibility of the air heated by the substrate unit being retained in the device can be reduced.

[0162] (13) The recording device 11 includes the fan 95 that causes air to flow out of the housing 16 from the duct 90. According to the above configuration, the possibility that the supply portion 67 is heated by the substrate unit can be reduced.

[0163] (14) The recording device 11 includes the fan 95 that causes air to flow from the duct 90 into the housing 16. According to the above configuration, the possibility that the supply portion 67 is heated by the substrate unit can be reduced.

[0164] Change Example

[0165] 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.

[0166] ·like Fig.23 As shown, the shielding plate 42 may also have more than one guide rib 97. In this modification, the shielding plate 42 has two guide ribs 97. The guide rib 97 extends vertically from the shielding surface 44. The two guide ribs 97 are located between the dividing ribs 45. The guide rib 97 extends from the first flow port 46 toward the second flow port 47. As a result, air becomes easier to be guided. Therefore, the cooling efficiency will be improved.

[0167] ·like Fig.24 As shown in FIG. 1 , the exhaust section 88 may also include a fan 95. In this modification, one of the two exhaust sections 88 included in the first substrate unit 83 also serves as the fan 95. Therefore, the exhaust section 88 also serves as the duct 90. In other words, it can be said that the duct 90 and the fan 95 constitute the exhaust section 88. In this modification, the duct 90 also serving as the exhaust section 88 is referred to as a duct 90A.

[0168] like Fig.25 As shown, a first duct opening 91A, a second duct opening 92A, and a third duct opening 93A are formed on the duct 90A. The first duct opening 91A communicates with the second flow opening 47. The first duct opening 91A also communicates with the inside of the power supply housing 85. Therefore, when the exhaust unit 88 is driven, air passes through the duct 90A and flows out of the power supply housing 85 to the outside of the recording device 11.

[0169] ·like Fig.26 as well as Fig. 27As shown, the device body 12 may also include a loading portion 99. The recorded medium M1 is loaded on the loading portion 99. The loading portion 99 is, for example, a tray. The loading portion 99 is located at the upper portion of the housing 16. The loading portion 99 is located above the recording portion 59. The loading portion 99 is located above the mounting portion 68. The loading portion 99 overlaps with the recording portion 59 when viewed from the vertical direction D3. Specifically, the loading portion 99 overlaps with the head 60 located at the recording position P1 when viewed from the vertical direction D3. The loading portion 99 overlaps with the head 60 located at the retreat position P2 when viewed from the vertical direction D3. In addition, the loading portion 99 overlaps with the mounting portion 68 when viewed from the vertical direction D3. Specifically, the loading portion 99 overlaps with the storage portion 70 when viewed from the vertical direction D3. The loading portion 99 overlaps with the relay member 71 when viewed from the vertical direction D3. In addition, in this modification example, the storage section 76 and the processing section 13 may be provided, or the storage section 76 and the processing section 13 may not be provided.

[0170] The flow channel space A3 may be defined by the mounting portion 99. Specifically, the flow channel space A3 may be defined by the second frame 28 and the mounting portion 99. In this case, the flow channel 72 is protected by the second frame 28 and the mounting portion 99.

[0171] ·like Fig.28 as well as Fig.29 As shown, the flow channel space A3 may also be defined by the processing section 13. Specifically, the flow channel space A3 may also be defined by the second frame 28 and the processing section 13. In this case, the flow channel 72 is protected by the second frame 28 and the processing section 13.

[0172] ·like Fig.30 As shown in FIG. 1 , the device body 12 may include a loading portion 99 above the storage portion 76. In this modification, the loading portion 99 overlaps with the storage portion 76 when viewed from the vertical direction D3.

[0173] The liquid ejected by the recording unit 59 is not limited to ink, and may be, for example, a liquid in which particles of a functional material are dispersed or mixed in a liquid. For example, the recording unit 59 may eject a liquid containing a material such as an electrode material or a pixel material used in the manufacture of a liquid crystal display, an electroluminescent display, or a surface-emitting display in a dispersed or dissolved form.

[0174] The user may store arbitrary items in the storage section 76 , that is, not only the manual for use of the recording device 11 but also the replacement storage body 69 , the replacement waste liquid tank 66 , the medium M1 , and the like.

[0175] Technical Thought

[0176] Hereinafter, the technical ideas and effects grasped from the above-mentioned embodiments and modified examples will be described.

[0177] (A) The recording device comprises: a recording unit that records an image on a medium by ejecting liquid onto the medium; a supply unit that supplies liquid to the recording unit; a substrate unit; and a frame on which the substrate unit is mounted, the frame being located between the supply unit and the substrate unit, and the substrate unit being mounted on the frame in a manner that defines a flow space for air to flow between the substrate unit and the frame. According to the above structure, by allowing air to flow in the flow space, the heat of the substrate unit becomes less likely to spread to the supply unit. As a result, the possibility of the supply unit being heated by the substrate unit can be reduced.

[0178] (B) The recording device may also be provided with a housing, the housing accommodating the recording unit, the supply unit, the substrate unit, and the frame, the frame having an opposing surface opposed to the substrate unit, the opposing surface extending in a vertical direction and a direction intersecting the vertical direction, the housing having a surface extending along the opposing surface, and a through hole opening on the surface for connecting the flow space with the outside of the housing. According to the above structure, air can flow into the flow space through the through hole, or flow out of the flow space through the through hole, thereby making it easier for air to flow in the flow space. Thus, the possibility of the supply unit being heated by the substrate unit can be reduced.

[0179] (C) The recording device may also be provided with a shielding plate, the shielding plate being mounted on the frame and being located between the supply section and the substrate unit, the frame having a plurality of frame members, the frame members being arranged so as to have gaps in the vertical direction, the shielding plate being mounted on the plurality of frame members so as to cover the gaps between the frame members. According to the above structure, the possibility that the heat of the substrate unit passes through the gaps between the frame members and spreads to the supply section can be reduced.

[0180] (D) In ​​the above recording device, the plurality of frame members may each have an opposing surface opposed to the substrate unit, the opposing surface extending in one direction and in a vertical direction, the shielding plate being mounted on the opposing surface, and the shielding plate overlapping the supply unit when the opposing surface is viewed from the front. According to the above structure, the heat spreading from the substrate unit to the supply unit is effectively shielded by the shielding plate.

[0181] (E) The recording device may also be provided with a conveying unit that conveys the medium, the frame having an opposing surface that is opposed to the substrate unit, the opposing surface extending in one direction and in a vertical direction, and the supply unit being located between the frame and the conveying unit when viewed from the one direction. According to the above structure, the heat of the substrate unit is less likely to spread to the conveying unit.

[0182] (F) In the above-mentioned recording device, it can also be set that the substrate unit is a first substrate unit, the frame is a first frame, and the recording device includes: a second substrate unit; a second frame on which the second substrate unit is installed; a pipe that connects the flow space to the outside of the recording device, the supply part has a flow channel connected to the recording part, the second frame is located between the supply part and the second substrate unit, and defines the flow channel space where the flow channel is located, and the pipe connects the flow space to the flow channel space. According to the above-mentioned structure, both the flow space and the flow channel space are connected to the outside of the recording device through the pipe. As a result, the structure of the recording device becomes simpler compared to the case where the flow space and the flow channel space are separately connected to the outside of the recording device.

[0183] (G) The recording device may also be provided with a housing, the housing accommodating the recording portion, the supply portion, the first substrate unit, the second substrate unit, the first frame, and the second frame, the first frame having a first opposing surface opposed to the first substrate unit, the first opposing surface extending in a first direction and a vertical direction, the second frame having a second opposing surface opposed to the second substrate unit, the second opposing surface extending in a second direction and a vertical direction, the second direction being a direction different from the first direction, the housing having a surface extending along the second opposing surface, a through-port opening being opened on the one surface for connecting the flow space to the outside of the housing, the pipe being connected to the through-port opening. According to the above structure, the flow space and the flow channel space are connected to the outside of the recording device through the through-port opening and the pipe. Thus, the possibility of heat from the substrate unit being retained in the housing can be reduced.

[0184] (H) In the above recording device, the one surface may be the rear surface of the housing. Usually, the user operates the recording device from the front surface of the housing. Therefore, according to the above structure, the possibility of the air flowing into the housing through the through-hole or the air flowing out of the housing through the through-hole affecting the user can be reduced.

[0185] (I) In the above-mentioned recording device, the duct may be located at a position overlapping with the flow space when viewed from the first direction, and at a position overlapping with the flow channel space when viewed from the second direction. According to the above-mentioned structure, the duct becomes easy to communicate with the flow space and the flow channel space.

[0186] (J) The recording device may also include a storage portion, the storage portion is configured to store items, the storage portion is located above the recording portion, and the flow channel space is defined by the second frame and the storage portion. According to the above structure, the flow channel can be protected by the second frame and the storage portion.

[0187] (K) The recording device may also include a processing unit that processes the medium recorded by the recording unit, the processing unit being located above the storage unit and overlapping the storage unit when viewed from a vertical direction. According to the above structure, the possibility of the lower edge space of the recording device becoming larger can be reduced by the processing unit.

[0188] (L) The recording device may also include a processing unit that processes the medium recorded by the recording unit, the processing unit being located above the recording unit, and the flow channel space being defined by the second frame and the processing unit. According to the above configuration, the flow channel can be protected by the second frame and the processing unit.

[0189] (M) The recording device may also include a loading unit for loading the medium recorded by the recording unit, the loading unit being located above the recording unit, and the flow channel space being defined by the second frame and the loading unit. According to the above structure, the flow channel can be protected by the second frame and the loading unit.

[0190] (N) In the above-mentioned recording device, it is also possible to set the uppermost end of the duct to be located at a position above the uppermost end of the first substrate unit and above the uppermost end of the second substrate unit in the vertical direction. The air heated by the substrate unit is likely to be retained at the upper part. Therefore, according to the above-mentioned structure, the air heated by the substrate unit is likely to flow together with the air flowing into the device from the duct or the air flowing out of the device from the duct. As a result, the possibility of the air heated by the substrate unit being retained in the device can be reduced.

[0191] (O) The recording device may include a fan that causes air to flow out of the recording device from the duct. According to the above configuration, the possibility that the supply unit is heated by the substrate unit can be reduced.

[0192] (P) The recording device may include a fan that causes air to flow from the duct into the recording device. According to the above configuration, the possibility that the supply unit is heated by the substrate unit can be reduced.
