Description

Technical Field

[0001] This invention relates to a recording device. Background Technology

[0002] Large-format inkjet printers have long been known as recording devices. In such recording devices, there exists a recording mechanism that uses a recording medium wound into a roll. For example, Patent Document 1 discloses a recording device that holds two rolls before and after recording.

[0003] However, the recording device described in Patent Document 1 presents the problem of requiring a relatively large installation space. Specifically, in this recording device, a foot supports the frame, and a roll body is positioned in front of and behind the foot. Therefore, it is relatively large in the front-to-back direction, requiring a relatively large installation space. Furthermore, space is needed for the user to work from behind when installing a new roll body. Moreover, there is a problem that the appearance has many irregularities, making it difficult to improve design flexibility.

[0004] In contrast, when the entire device is designed as a rectangular frame, housing the printing unit, feet, and roll body within this frame, the mechanical strength of the recording device can easily decrease. Specifically, in the aforementioned structure, the side frames extend downwards, resulting in insufficient frame rigidity. Therefore, a recording device that offers superior design and mechanical strength compared to conventional designs while reducing installation space is sought.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2021-133527 Summary of the Invention

[0017] In the embodiments described below, a large-format inkjet printer is exemplified as a recording device, and the description is based on the accompanying drawings. For ease of illustration, the sizes of the various components differ from the actual dimensions. In large-format inkjet printers, for example, recording media with a width of 297 mm or more can be used.

[0018] In the following figures, the XYZ axes are labeled as mutually orthogonal coordinate axes as needed, and the direction indicated by each arrow is designated as the + direction, and the direction opposite to the + direction is designated as the - direction. When the recording device is set on a horizontal plane, the Z-axis is along the vertical direction. Sometimes the +Y direction is referred to as forward and the -Y direction as backward, and sometimes the +Z direction is referred to as upward and the -Z direction as downward.

[0019] In this invention, the first direction is along the X-axis, the second direction intersecting the first direction is along the Y-axis, and the third direction intersecting both the first and second directions is along the Z-axis. The direction along the X-axis will be referred to simply as the X-direction, the direction along the Y-axis will be referred to simply as the Y-direction, and the direction along the Z-axis will be referred to simply as the Z-direction.

[0020] The recording medium is unwound from the roll and recorded. On the path of the recording medium that discharges the recording material from the recording device, the roll side is sometimes referred to as upstream, the side where the recording material is discharged is sometimes referred to as downstream, and the direction from upstream to downstream is sometimes referred to as the conveying direction.

[0021] like Figure 1 As shown, the recording device 10 according to this embodiment has a generally cuboid-shaped frame 12 that is longer in the X direction and taller in the Z direction. The frame 12 includes a front surface 13, a back surface 14, side surfaces 15 and 16, a top surface 17, and a bottom surface 18.

[0022] The recording device 10 has a recording section 30, a support section 31, and a recording medium holding section 20 inside the frame 12. Although not shown in the figure, the recording device 10 also has a transport path, a frame that serves as the skeleton of the recording device 10, and a control section. In addition, the recording device 10 has four feet 11 on its bottom surface 18.

[0023] The recording unit 30 is disposed above the interior of the housing 12. The recording unit 30 includes a carriage 33 and a recording head 34. The carriage 33 is disposed above the support 31. The recording head 34 is disposed below the carriage 33 and is opposite to the support 31 in the Z direction.

[0024] The recording head 34 has a nozzle surface (not shown) on the surface opposite the support portion 31. Multiple nozzle rows are arranged on the nozzle surface. Each of the multiple nozzle rows consists of multiple nozzles, which independently eject inks of colors such as blue-green, magenta, yellow, and black. These inks are supplied to the recording head 34 from the ink cartridge 35 via piping (not shown). In this specification, the liquid ejected by the recording unit 30 includes not only the various colors of inks mentioned above, but also transparent inks, processing liquids, etc., and is simply referred to as ink.

[0025] When recording is performed by the recording head 34 on a recording medium (not shown), the support portion 31 supports the recording medium. The support portion 31 has a generally rectangular shape that is elongated in the X direction. The recording head 34 is supported on a part of a frame described later and moves in the X direction within a range corresponding to the support portion 31.

[0026] On the front surface 13 of the frame 12, there is a paper discharge port 53 and a roll body storage port 27. The paper discharge port 53 is a narrow slit located in front of the support portion 31 and elongated in the X direction corresponding to the width of the recording medium. In the paper discharge port 53, the recorded material, which is the recording medium to be recorded, is discharged from the inside of the frame 12 to the front outside.

[0027] The roll body storage opening 27 is a generally rectangular opening corresponding to the two roll bodies 25a and 25b. The roll body storage opening 27 extends in the Z direction from near the bottom surface 18 of the frame 12 to approximately the middle of the height of the frame 12, and is longer than the length of the roll bodies 25a and 25b in the X direction. The roll bodies 25a and 25b can be visually identified from the +Y direction via the roll body storage opening 27.

[0028] In roll 25a, a recording medium 22 is wound on the core member 23a before recording. In roll 25b, a recording medium 22 is wound on the core member 23b before recording. Rolls 25a and 25b are generally cylindrical, with the height of the cylinder along the X direction. Roll 25b is positioned near the bottom surface 18 of the frame 12, and roll 25a is positioned above roll 25b. Examples of recording media 22 include coated paper, resin films such as vinyl chloride, and fabric.

[0029] The recording medium holding unit 20 holds the roll bodies 25a and 25b, and supplies the recording medium 22 before recording from the roll bodies 25a and 25b to the transport path.

[0030] An input section 59 is disposed on the upper surface 17 in the -X and +Y directions. The input section 59 is, for example, a touch-screen liquid crystal display device. The input section 59 is electrically connected to the control section. Inputs for various operations of the recording device 10 are performed in the input section 59, and various information of the recording device 10 is displayed.

[0031] The control unit includes a CPU (Central Processing Unit), system bus, ROM (Read-Only Memory), RAM (Random Access Memory), etc. The control unit is electrically connected to each component of the recording device 10 and provides comprehensive control over the operation of the recording device 10. The recording device 10 can also be operated by an information device such as a personal computer via the control unit.

[0032] like Figure 2 As shown, in the recording device 10, the main structure is arranged around the base frame 67. The base frame 67 extends in the X direction. Here, Figure 2 The cross-section is a division of the pipe 73 along the YZ plane. Four feet 11 are arranged on the lower frame 65 that forms the bottom surface 18. Furthermore, the structure of the frame in the recording device 10, including the base frame 67, will be described later.

[0033] The recording device 10 is mounted on the mounting surface S via four feet 11 that support the lower frame 65. The feet 11 are, for example, casters, adjusters, or other components capable of supporting and securing weights. The number of feet 11 is not limited to four; five or more may be included. Furthermore, both casters and adjusters may be included.

[0034] In the recording apparatus 10, the recording medium 22 is transported from the recording medium holding part 20 through the transport path 40 and the position opposite the recording part 30 and the support part 31 to the paper discharge port 53.

[0035] Although not shown in the diagram, the recording medium holding section 20 has a recording medium 22 delivery mechanism corresponding to each of the roll bodies 25a, 25b. The user selects which recording medium 22 from the roll bodies 25a, 25b to use. The recording medium 22 is delivered rearward and upward from the recording medium holding section 20 and proceeds along the transport path 40.

[0036] The transport path 40 transports the recording medium 22 to the support portion 31. The transport path 40 is formed by lower surface side path forming members 41a and 41b, inclined surfaces 44a and 44b, rear surface side path forming member 45, and upper surface side path forming member 47, etc. Regarding these members forming the transport path 40, since the recording medium 22 slides, materials such as resin with a low coefficient of friction are used. In addition, the lower surface side path forming member 41a is an example of the lower surface side path forming member of the present invention.

[0037] The conveying path 40 includes an intermediate roller 42 and a conveying roller 43, which are used to convey the recording medium 22 in the conveying direction. In the intermediate roller 42 and the conveying roller 43, materials with a high coefficient of friction, such as rubber or resin elastomers, are used on the surfaces that contact the recording medium 22.

[0038] The conveying path 40 extends from below, through the rear, to above the base frame 67. Along the conveying path 40, from upstream to downstream, the support portion 31 is provided with, in sequence, a lower surface side path forming member 41a and an inclined surface 44a or a lower surface side path forming member 41b and an inclined surface 44b, a rear surface side path forming member 45, an intermediate roller 42, an upper surface side path forming member 47, and a conveying roller 43.

[0039] Lower surface side path forming components 41a and 41b, and inclined surfaces 44a and 44b are disposed below the base frame 67. Lower surface side path forming components 41a and inclined surfaces 44a are disposed corresponding to the roll body 25a. Lower surface side path forming components 41b and inclined surfaces 44b are disposed corresponding to the roll body 25b. Lower surface side path forming components 41a and 41b correspond to the back side of the recording surface of the recording medium 22, and inclined surfaces 44a and 44b correspond to the recording surface of the recording medium 22.

[0040] The rear surface side path forming component 45 is positioned behind the base frame 67. The recording medium 22 is conveyed upward along the rear surface side path forming component 45.

[0041] The transport direction of the recording medium 22 changes approximately in the +Y direction at the intermediate roller 42. In the transport direction of the recording medium 22 being transported to the support surface 31s of the support portion 31, the intermediate roller 42, the upper surface side path forming member 47, and the transport roller 43 are located on the upstream side and are arranged above and behind the base frame 67.

[0042] The intermediate roller 42 and the conveyor roller 43, driven by a motor (not shown), rotate counterclockwise when viewed from the side in the -X direction, thereby conveying the recording medium 22 downstream. An upper surface path forming member 47 is located between the intermediate roller 42 and the conveyor roller 43 and guides the recording medium 22.

[0043] A support portion 31 is disposed downstream of the conveyor roller 43 and above the base frame 67. A recording head 34 of the recording unit 30 is disposed above the support portion 31. The support portion 31 has a negative pressure chamber 31r, a support surface 31s, and multiple openings described later. The support surface 31s supports the recording medium 22 at a position opposite to the recording unit 30. Recording is performed on the recording medium 22 at this position.

[0044] The negative pressure chamber 31r is disposed below the support surface 31s. Multiple openings are provided on the support surface 31s and communicate from the interior of the negative pressure chamber 31r to the support surface 31s. The support surface 31s is disposed above the negative pressure chamber 31r opposite the recording unit 30 in the Z direction.

[0045] The recording device 10 includes a negative pressure mechanism 75 and a conduit 73. The negative pressure mechanism 75 is positioned in front of the base frame 67. The conduit 73 is located inside the base frame 67 and is curved. One end of the conduit 73 is connected to the rear of the negative pressure mechanism 75, and the other end protrudes upwards from the base frame 67 and communicates with the negative pressure chamber 31r.

[0046] The conduit 73 connects the negative pressure chamber 31r to the negative pressure mechanism 75. The negative pressure mechanism 75 includes, for example, a suction fan and sets the negative pressure chamber 31r to a negative pressure. That is, the negative pressure generated by the negative pressure mechanism 75 causes the recording medium 22 to be adsorbed onto the support surface 31s. As a result, wrinkles and positional shifts of the recording medium 22 at the support portion 31 can be suppressed.

[0047] The recording head 34 is located below the carriage 33 and is positioned opposite the support surface 31s. Although not shown in the figure, the recording head 34 includes an actuator that serves as a drive unit for ink ejection. Examples of actuators include piezoelectric elements, electromechanical conversion elements that displace the diaphragm by electrostatic adsorption, and electrothermal conversion elements that eject ink droplets by bubbles generated by heating.

[0048] The carriage 33 is supported on a guide rail (not shown) of the main frame 61. The main frame 61 is a quadrangular prism with a generally rectangular cross-section. The main frame 61 is positioned above the intermediate roller 42 with the height of the quadrangular prism along the X direction.

[0049] The main frame 61 supports the carriage 33 of the recording unit 30 via guide rails in a manner that allows it to move in the X direction. That is, while supported by the main frame 61, the carriage 33 scans in the X direction by being driven by a motor (not shown). By feeding the recording medium 22 while the carriage 33 is scanning and applying ink from the recording head 34 to the recording medium 22, images, colors, text, etc., are recorded on the recording medium 22, thereby creating a recorded object.

[0050] The recording device 10 includes a maintenance tank 83 for recovering ink discarded on the support surface 31s during borderless printing or similar processes. The maintenance tank 83 is positioned above and in front of the base frame 67. Although not shown in the figure, a guide section is connected to the maintenance tank 83 from the support surface 31s. Ink is guided from the support surface 31s into the maintenance tank 83 via this guide section. Inside the maintenance tank 83, an absorbent material is disposed to absorb and retain the ink.

[0051] A cutting section 50 is disposed downstream of the support section 31. The cutting section 50 cuts the recording medium 22 at the desired position along the X direction. Then, the recording medium 22 is discharged forward from the paper discharge port 53 as a recording material.

[0052] like Figure 3 As shown, the frame 60 of the recording device 10 includes a main frame 61, a base frame 67, a lower frame 65, a pair of side frames 62 and 63, a sub-frame 69, and a sub-base frame 68. These frames are assembled to form the frame 60. The frame 60 holds the recording unit 30, the support unit 31, the transport path 40, and the recording medium holding unit 20.

[0053] The lower frame 65 is located at the bottom of the frame 60. The lower frame 65 is a longer component in the X direction, extending along both the X and Y directions. Although not shown in the figure, the lower frame 65 has multiple ribs and bends extending along the X direction. In the X direction, the length of the lower frame 65 is approximately equal to the length of the frame 12 of the recording device 10.

[0054] A pair of side frames 62 and 63 are respectively fixed at their lower ends to the surface above the lower frame 65 and are erected in the Z direction. When viewed from the Y direction, side frame 62 is positioned in the +X direction, and side frame 63 is positioned in the -X direction. Side frame 62 has a first portion 62a and a second portion 62b. Side frame 63 has a first portion 63a and a second portion 63b.

[0055] The first portions 62a and 63a extend in the Z and Y directions. The second portion 62b bends and extends from the first portion 62a in the X direction, specifically in the -X direction. The second portion 63b bends and extends from the first portion 63a in the X direction, specifically in the +X direction. A pair of side frames 62 and 63 are arranged opposite each other in the X direction at a predetermined interval. The predetermined interval refers to, for example, a distance longer than the length in the X direction of the aforementioned roll body 25a.

[0056] The four feet 11 are configured such that, when viewed from the Z direction, they overlap with any one of the first portions 62a, 63a and the second portions 62b, 63b, respectively. Specifically, the front foot 11 in the -X direction overlaps with the first portion 63a, and the rear foot 11 in the -X direction overlaps with the second portion 63b. Furthermore, the front foot 11 in the +X direction overlaps with the first portion 62a, and the rear foot 11 in the +X direction overlaps with the second portion 62b.

[0057] Therefore, feet 11 are provided at the positions where the lower frame 65 is fixed to the side frames 62 and 63, thus strengthening the lower frame 65 and suppressing deformation of the lower frame 65. In addition, the recording device 10 can be stably mounted by means of the four feet 11.

[0058] The base frame 67 is a roughly prismatic box shape, with the height of the prism along the X-axis. The base frame 67 is held between the pair of side frames 62 and 63 in the Z-direction, slightly above their center. The base frame 67 holds a portion of the main structure of the recording device 10.

[0059] The aforementioned recording medium holding section 20 is disposed between a pair of side frames 62 and 63 in the X direction, and between the base frame 67 and the lower frame 65 in the Z direction.

[0060] The main frame 61 is supported on the upper ends of a pair of side frames 62 and 63. The main frame 61 extends in the +X direction relative to the side frames 62 and in the -X direction relative to the side frames 63. In the X direction, the length of the main frame 61 is approximately equal to the length of the lower frame 65. Since the main frame 61 and the lower frame 65 are fixed together relative to the pair of side frames 62 and 63 in the X direction, the rigidity of the frame 60 is further improved.

[0061] Subframe 69 and subbase frame 68 are configured in the -X direction, which is one side of the X direction. Subframe 69 and subbase frame 68 are not limited to being configured in the -X direction, but can also be configured in the X direction on both sides or one side of the -X direction on one side and the +X direction on the other side.

[0062] The lower end of the sub-frame 69 is fixed to the surface above the lower frame 65 and is erected along the Z direction. The side frame 63 and the sub-frame 69 are positioned opposite each other in the X direction, separated by the sub-base frame 68. The upper end of the sub-frame 69 supports the main frame 61.

[0063] The sub-base frame 68 has three walls 68a, 68c, and 68d extending in the X direction. Wall 68a is along the XY plane, and walls 68c and 68d are along the XZ plane. The ink cartridge 35 is mounted on top of the sub-base frame 68. This increases the rigidity of the frame 60 and allows for efficient and flexible use of the space inside the frame 60. Additionally, an ink container with a larger capacity than the ink cartridge 35 can be mounted between the sub-base frame 68 and the lower frame 65.

[0064] When viewed from the Y direction, the base frame 67 and the sub-base frame 68 are located at different positions in the Z direction. Therefore, the rigidity of the frame 60 is further improved.

[0065] Side frames 62 and 63, lower frame 65, base frame 67, sub-base frame 68, and sub-frame 69 are constructed from flat plates made of iron, aluminum, alloys, etc., and are shaped through processes such as drilling and bending. In the assembly of frame 60, assembly, fastening with screws, rivets, etc., and joining methods are used individually or in combination. In addition to the aforementioned frames, frame 60 may also have additional structural components.

[0066] like Figure 4 As shown, the base frame 67 has an upper wall 67a, a lower wall 67b, a front wall 67c, and a rear wall 67d, which extend in the X direction. In the following description, these four walls are sometimes collectively referred to as the four walls 67w.

[0067] The four walls 67w are approximately rectangular in shape and elongated in the X direction. The upper wall 67a and the lower wall 67b are along the XY plane and are opposite each other in the Z direction. The front wall 67c and the rear wall 67d are along the XZ plane and are opposite each other in the Y direction.

[0068] In the upper wall surface 67a, the end in the +X direction is designated as end 67a1, and the end in the -X direction is designated as end 67a2. In the lower wall surface 67b, the end in the +X direction is designated as end 67b1, and the end in the -X direction is designated as end 67b2. In the front wall surface 67c, the end in the +X direction is designated as end 67c1, and the end in the -X direction is designated as end 67c2. In the rear wall surface 67d, the end in the +X direction is designated as end 67d1, and the end in the -X direction is designated as end 67d2.

[0069] On the upper wall surface 67a, a through hole 67h1 is provided at an end 67a2 relative to the center in the X direction. On the front wall surface 67c, a through hole 67h2 is provided at an end 67c2 relative to the center in the X direction. The through holes 67h1 and 67h2 correspond to the pipe 73 shown in dashed lines. The pipe 73 protrudes upward from the through hole 67h1 and connects to the aforementioned negative pressure chamber 31r. Furthermore, the pipe 73 is connected to the aforementioned negative pressure mechanism 75 via the through hole 67h2.

[0070] like Figure 5 As shown, the four walls 67w of the base frame 67, at the -X direction (which is one side of the X direction), have ends 67a2, 67c2, and 67d2 fixed from the +X direction to one of the pair of side frames 62 and 63, namely side frame 63. Furthermore, although all four ends 67a2, 67b2, 67c2, and 67d2 of the four walls 67w could be fixed relative to the side frame 63, it is sufficient that at least two of the four ends 67a2, 67b2, 67c2, and 67d2 are fixed.

[0071] Although the illustration is omitted, similarly to the above, the four walls 67w, at the +X direction (which is the opposite side of the X direction), have their ends 67a1, 67c1, and 67d1 fixed from the -X direction to the other side of the pair of side frames 62 and 63, namely the side frame 62. Furthermore, although all four ends 67a1, 67b1, 67c1, and 67d1 of the four walls 67w could be fixed relative to the side frame 62, it is sufficient that at least two of the four ends 67a1, 67b1, 67c1, and 67d1 are fixed.

[0072] Based on the above, at least two of the four wall surfaces 67w are clamped and fixed by a pair of side frames 62, 63. Therefore, the rigidity of the frame 60 can be further improved.

[0073] The ends of the shafts of the intermediate roller 42 and the conveyor roller 43 in the -X direction are rotatably held on the side frame 63. Although not shown in the figure, the ends of the shafts of the intermediate roller 42 and the conveyor roller 43 in the +X direction are rotatably held on the side frame 62.

[0074] When viewed from the Y direction, the main frame 61 is positioned rearward and above the base frame 67. This ensures the movable area of ​​the recording section 30 (not shown), which is supported on the main frame 61 and moves in the X direction.

[0075] When viewed from the Z direction, the recording medium holding part 20 is located on the front wall surface 67c side of the base frame 67 in the Y direction. Furthermore, when viewed from the Z direction, the recording medium holding part 20 is configured to overlap with the base frame 67 in at least a portion in the Y direction. Therefore, the length in the front-to-back direction is shortened, thereby enabling miniaturization of the recording device 10.

[0076] like Figure 6 As shown, conduits 73, serving as functional components related to recording in the recording unit 30, are arranged on the inner sides of the four walls 67w of the base frame 67. Therefore, the interior of the base frame 67 is utilized effectively and flexibly, enabling miniaturization of the recording device 10. Furthermore, the aforementioned functional components arranged on the inner sides of the four walls 67w are not limited to the conduits 73. Here, "functional components" refers to all structures mounted on the base frame 67, such as the negative pressure chamber 31r, the negative pressure mechanism 75, and the maintenance tank 83.

[0077] A negative pressure chamber 31r is maintained above the upper wall 67a of the four walls 67w of the base frame 67. Therefore, multiple openings (not shown) communicating with the negative pressure chamber 31r from the support surface 31s are arranged on the outside of the base frame 67. This eliminates the need for holes corresponding to the multiple openings in the base frame 67, thereby improving the rigidity of the base frame 67. Furthermore, since the negative pressure chamber 31r is located on the outside of the base frame 67, its integrity is improved.

[0078] Part or all of the negative pressure chamber 31r can also be configured inside the base frame 67. That is, for example, the negative pressure chamber 31r can also be held below the upper wall 67a. Thus, the interior of the base frame 67 is effectively and flexibly utilized, thereby enabling the recording device 10 to be miniaturized.

[0079] The negative pressure mechanism 75 is positioned in the +Y direction of the front wall 67c, one of the four walls 67w of the base frame 67. Therefore, air can flow from the negative pressure mechanism 75 to the front of the recording device 10 via the front wall 67c.

[0080] Part or all of the negative pressure mechanism 75 can also be configured inside the base frame 67. That is, for example, the negative pressure mechanism 75 can also be held in the -Y direction of the front wall surface 67c. Thus, the interior of the base frame 67 is effectively and flexibly utilized, thereby enabling the recording device 10 to be miniaturized.

[0081] The maintenance tank 83 is positioned between the upper wall 67a of the base frame 67 and the negative pressure chamber 31r.

[0082] The lower surface side path forming component 41a is held at the lower wall surface 67b of the four walls 67w of the base frame 67. The rear surface side path forming component 45 is held at the rear wall surface 67d of the four walls 67w of the base frame 67. The upper surface side path forming component 47 is held at the upper wall surface 67a of the four walls 67w of the base frame 67.

[0083] As mentioned above, the various components are maintained on the four walls 67w of the basic frame 67, thereby making effective and flexible use of the four walls 67w.

[0084] like Figure 7 As shown, the support portion 31 has an elongated shape in the X direction. The upper part of the pipe 73 communicates with the negative pressure chamber 31r. Additionally, in Figure 7 In the middle, it indicates that the pipe 73 is cut off along the YZ plane by a surface that is equally divided in the X direction.

[0085] The negative pressure chamber 31r is a narrow, elongated chamber-shaped space in the X direction. Above the negative pressure chamber 31r, a support surface 31s is disposed. In the negative pressure chamber 31r, except for the area communicating with the pipe 73 and the multiple openings of the support surface 31s (described later), the portion is blocked.

[0086] A guide section 85 is connected to the support surface 31s in the +Y direction. The surface above the guide section 85 slopes downward in the +Y direction. As a result, the guide section 85 guides the ink discarded on the support surface 31s to the aforementioned maintenance tank 83.

[0087] like Figure 8 As shown, a plurality of openings 31h communicating with the negative pressure chamber 31r are arranged on the support surface 31s. When the negative pressure chamber 31r is set to negative pressure, air is drawn into the negative pressure chamber 31r through the plurality of openings 31h. As a result, the recording medium 22 (not shown) is adsorbed onto the support surface 31s.

[0088] In the support surface 31s, a groove 31g is provided next to the area where multiple openings 31h are configured. The groove 31g includes multiple grooves extending in the Y direction. In the groove 31g, the ink sprayed onto the support surface 31s is guided in the +Y direction by a guide portion 85.

[0089] like Figure 9 As shown, a plurality of shaft support components 91 and a pair of support support components 93 are arranged on the base frame 67.

[0090] Two shaft support members 91 are arranged on the upper wall 67a of the base frame 67, relatively inward from both ends in the X direction relative to the axes of the intermediate roller 42 and the conveyor roller 43. The shaft support members 91 are located below the intermediate roller 42 and the conveyor roller 43, and support the aforementioned axes in a rotatable manner. Because the shaft support members 91 support the aforementioned axes at two points, the occurrence of deflection in the intermediate roller 42 and the conveyor roller 43 can be suppressed, thereby improving the transportability of the recording medium 22. The number of shaft support members 91 is not limited to two; three or more may also be used.

[0091] A pair of support members 93 correspond to two shaft support members 91 and are positioned above, in the Z direction, of the negative pressure chamber 31r (not shown). Figure 10 As shown, each support member 93 is supported by the upper wall 67a of the base frame 67 and extends in the Y direction, supporting the shaft support member 91 near its end in the -Y direction. Furthermore, a support member 31 (not shown) is located above and supported below by the pair of support members 93. That is, the pair of support members 93 support the support member 31 and the two shaft support members 91.

[0092] Return to Figure 9 Three upper surface side path forming members 47 are arranged in the X direction. The three upper surface side path forming members 47 are held on the upper wall surface 67a of the base frame 67 in the X direction, outside the positions where the shaft support member 91 and the support member 93 are arranged. As a result, interference between the upper surface side path forming members 47 and the shaft support member 91 and the support member 93 can be prevented.

[0093] As mentioned above, the various components are maintained on the upper wall 67a of the base frame 67, thereby making effective and flexible use of the upper wall 67a.

[0094] According to this embodiment, the following effects can be obtained.

[0095] In the recording device 10, mechanical strength can be improved and installation space can be reduced. Specifically, the frame 60 is assembled from a lower frame 65, a pair of side frames 62 and 63, and a base frame 67. The base frame 67 has excellent rigidity due to its four walls 67w. The pair of side frames 62 and 63 sandwich and support the base frame 67 in the middle. The lower frame 65 supports the lower ends of the pair of side frames 62 and 63. Thus, a compact and highly rigid frame 60 is formed.

[0096] The frame 60 is assembled, and the main structure is held on the frame 60. Therefore, the irregularities in the shape can be reduced, thereby improving the design aesthetics of the recording device 10. Based on the above, a recording device 10 with excellent design and mechanical strength while reducing installation space can be provided.
