Description

[Technical field]

[0001] The present invention relates to a recording device for recording on a medium. [Background technology]

[0002] In a recording device, such as a printer, a cooling unit may be provided to cool an object that needs to be cooled. The recording device described in Patent Document 1 is provided with a cooling unit to cool a tank that contains ink. In the recording device described in Patent Document 1, an air intake port for taking in outside air and an exhaust port for discharging air from inside the device are provided on the same side of the device. The air intake port and the exhaust port are located in the central area in the height direction of the device, and the air intake port is located near the top of the exhaust port. When the exhaust fan is driven, the air that flows in from the air intake port advances horizontally toward the recording head, and when it hits the recording head, it advances downward with the recording head as a wall, then makes a U-turn toward the exhaust port and heads toward the exhaust port horizontally.

[0003] [Patent Document 1] JP 2020-26073 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the recording device described in Patent Document 1, it is necessary to form an air flow path that crosses the device in the horizontal direction. This makes it impossible to arrange large components at the positions where the air flow paths are formed, which not only reduces the degree of freedom in design but also may result in the device becoming larger in height. [Means for solving the problem]

[Figure 6] FIG. 4 is a cross-sectional view showing the inside of the head unit and the air intake guide. [Figure 7] FIG. 3 is an enlarged view of the main part of FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] The present invention will now be briefly described. The recording device of the first aspect comprises a recording unit which records on a medium, and a discharge tray which is located above the recording unit in the height direction of the device and supports the medium which has been recorded on and discharged, and is characterized in that an air flow path for cooling the recording unit is formed along the underside of the discharge tray.

[0008] According to this aspect, an air flow path for cooling the recording unit is formed along the underside of the discharge tray, i.e., the flow path is formed using the underside of the discharge tray, so there is no need to secure additional space inside the device for air to flow horizontally, resulting in improved design freedom and also preventing the device from becoming larger in height.

[0009] The second aspect is characterized in that, in the first aspect, an air intake is provided at the downstream end of the discharge tray in the media discharge direction, the recording unit is located upstream in the media discharge direction below the discharge tray, and the flow path runs from the air intake to the recording unit along the underside of the discharge tray. According to this aspect, an air intake port is provided at the downstream end of the discharge tray in the media discharge direction, the recording unit is located below the discharge tray and upstream in the media discharge direction, and the flow path runs from the air intake port toward the recording unit along the underside of the discharge tray, thereby achieving the effect of the first aspect described above.

[0010] A third aspect is characterized in that, in the second aspect, a protrusion that protrudes upward is formed on the discharge tray along the media discharge direction, and at least a portion of the air intake is formed in the protrusion.

[0011] According to this aspect, the ejection tray has a protrusion that protrudes the media upward along the media ejection direction, so that the media supported by the ejection tray bends in the width direction that intersects with the media ejection direction, improving the rigidity along the media ejection direction, thereby improving the alignment of the media on the ejection tray. Furthermore, since at least a portion of the air intake is formed in the protruding portion, an increase in size of the discharge tray that would otherwise be caused by providing the air intake can be suppressed, and thus an increase in size of the apparatus can be suppressed.

[0012] A fourth aspect is characterized in that, in the third aspect, the discharge tray has a first portion extending from the protrusion toward one end in a width direction intersecting the media discharge direction, and a second portion extending from the protrusion toward the other end in the width direction, and the air intake port extends toward one end in the width direction using the first portion.

[0013] According to this aspect, the air intake port extends toward one end in the width direction by utilizing the first portion, so that the air intake port can be formed over a wider range, and air intake efficiency can be improved.

[0014] A fifth aspect is characterized in that in any one of the first to fourth aspects, the air that has passed through the recording unit is exhausted from an exhaust port located above the discharge tray. If the exhaust port is located below the intake port, there is a risk that the hot air exhausted from the exhaust port will be taken in through the intake port. However, according to the present embodiment, the air that has passed through the recording section is exhausted from an exhaust port located above the discharge tray, thereby avoiding the above problem.

[0015] A sixth aspect is the fifth aspect, characterized in that the intake port and the exhaust port are provided at positions spaced apart from each other in the horizontal direction. According to this aspect, the intake port and the exhaust port are provided at positions spaced apart in the horizontal direction, thereby further reducing the risk of hot air discharged from the exhaust port being taken in through the intake port.

[0016] A seventh aspect is characterized in that, in any of the first to sixth aspects, the recording unit extends along a width direction intersecting the medium discharge direction and is provided with a heat dissipation member extending along the width direction, and air that has passed through the flow path to reach the recording unit is taken into the inside of the recording unit and flows in the width direction along the heat dissipation member.

[0017] According to this aspect, in a configuration in which the recording unit is extended along a width direction intersecting the medium discharge direction, air that reaches the recording unit through the flow path is taken inside the recording unit and flows in the width direction along the heat dissipation member, thereby improving the efficiency of heat dissipation from the heat dissipation member.

[0018] The eighth aspect is characterized in that, in the seventh aspect, the printer is provided with an opening for taking in air that passes through the flow path and reaches the recording unit into the interior of the recording unit, and at least a portion of the opening overlaps with the air intake in a normal direction relative to a support surface on which the discharge tray supports the medium.

[0019] According to this aspect, at least a portion of the opening overlaps with the air intake port in the normal direction to the support surface on which the discharge tray supports the medium, so that air taken in from the air intake port flows straight along the underside of the discharge tray toward the opening, improving the efficiency of air intake from the opening.

[0020] A ninth aspect is characterized in that, in any of the first to eighth aspects, the recording unit is arranged to be capable of moving forward and backward relative to a medium transport path formed in a position opposite the recording unit by moving along the underside of the discharge tray.

[0021] The recording unit may need to be configured to be able to advance and retreat with respect to the medium transport path for maintenance purposes. According to this aspect, the recording unit advances and retreats with respect to the medium transport path by moving along the underside of the discharge tray, so that the space required for the recording unit to advance and retreat can be reduced, and the size of the device can be reduced. Furthermore, since the recording portion can be prevented from being separated from the flow path, the recording portion can be efficiently cooled regardless of the position of the recording portion.

[0022] A tenth aspect is characterized in that, in the ninth aspect, the recording unit records on a medium by ejecting liquid from a liquid ejection head, and is provided with a liquid storage unit below the discharge tray for storing the liquid ejected from the recording unit, and the flow path faces the space in which the liquid storage unit is provided.

[0023] According to this aspect, the flow path faces the space in which the liquid storage portion is provided, so that part of the space in which the liquid storage portion is provided can be used as the flow path, thereby preventing the device from becoming large.

[0024] An eleventh aspect is the tenth aspect, characterized in that the liquid storage portion is detachable and is put into an attached state by moving in a direction retracting from the flow path. According to this aspect, the liquid storage unit is detachable and configured to be in the attached state by moving in a direction away from the flow path, so that a space for attaching and detaching the liquid storage unit is formed in the liquid storage unit at a position facing the flow path. Therefore, when the liquid storage unit is in the attached state, the area facing the flow path in the space where the liquid storage unit is provided increases, so that the flow path can be enlarged and the cooling target can be cooled more efficiently.

[0025] The present invention will be specifically described below. In the following, an inkjet printer 1 that performs recording by ejecting ink, which is an example of a liquid, onto a medium such as recording paper will be described as an example of a recording device. In the following, the inkjet printer 1 will be abbreviated to printer 1. The XYZ coordinate system shown in each figure is an orthogonal coordinate system, with the Y axis direction being the direction that intersects with the medium transport direction, i.e., the medium width direction, and also the device depth direction. The +Y direction of the Y axis direction is the direction from the front of the device to the rear of the device, and the -Y direction is the direction from the rear of the device to the front of the device.

[0026] The X-axis direction is the width direction of the device, with the +X direction being the left side and the -X direction being the right side as seen by the operator of the printer 1. The Z-axis direction is the vertical direction, or the height direction of the device, with the +Z direction being the upward direction and the -Z direction being the downward direction. In the following, the direction in which the medium is transported may be referred to as "downstream," and the opposite direction may be referred to as "upstream." In each figure, the medium transport path is indicated by a dashed line. In the printer 1, the medium is transported through the medium transport path indicated by the dashed line.

[0027] The F-axis direction is the medium transport direction between a line head 51 and the transport belt 13, which will be described later, i.e., in the recording area, with the +F direction being the downstream transport direction and the opposite -F direction being the upstream transport direction. The V-axis direction is the movement direction of the head unit 50, which will be described later, with the +V direction being the direction in which the head unit 50 moves away from the transport belt 13 and the -V direction being the direction in which the head unit 50 moves closer to the transport belt 13. In this embodiment, the +V direction is the medium ejection direction. In this embodiment, the V axis direction is also the direction along the inclination of the ejection tray 8, which will be described later.

[0028] As shown in FIG. 1, the printer 1 is configured as a multifunction device equipped with a scanner unit 9, which is an example of an image reading device, on top of a device main body 2 that records on a medium such as recording paper. An operation panel 7 is disposed on the front side of the device body 2, and part of the front and part of the left side at the top of the device body 2 are open structures formed as areas for removing the medium that has been recorded on and ejected. Reference numeral 8 denotes an ejection tray that supports the ejected medium.

[0029] The discharge tray 8 has a protrusion 8a that protrudes upward along the V-axis direction, i.e., the medium discharge direction. The protrusion 8a is provided in approximately the center of the discharge tray 8 in the Y-axis direction, i.e., the medium width direction. This protrusion 8a causes the medium supported by the discharge tray 8 to bend in the medium width direction, thereby improving rigidity along the medium discharge direction, suppressing curling of the medium on the discharge tray 8, and improving alignment.

[0030] In the discharge tray 8, on the upstream side in the -V direction, ie, in the medium discharge direction, support surfaces 8b for supporting the medium are formed on both sides of the protruding portion 8a in the medium width direction. In addition, in the +V direction of the discharge tray 8, i.e., downstream in the medium discharge direction, the first portion 8c extends from the protruding portion 8a in the +Y direction, and the second portion 8d extends from the protruding portion 8a in the -Y direction. The first portion 8c forms a surface higher than the second portion 8d and extends at an angle along the V axis direction. In this embodiment, the second portion 8d is a surface parallel to the horizontal direction. By forming the second portion 8d in this manner, the downstream end of the discharged medium in the medium discharge direction rises above the second portion 8d, making it easier to remove the medium.

[0031] An intake port 45 for taking in outside air is formed at the downstream end of the discharge tray 8 in the medium discharge direction. Additionally, an exhaust port 46 for discharging air from inside the device is formed behind the operation panel 7. The printer 1 can take in air from the intake port 45 into the device, and the taken-in air passes through flow paths Fa, Fb, and Fc before being discharged as shown by arrow Fd. In the manner described above, an air flow path for cooling the head unit 50, which will be described later, is formed, and this will be explained again later.

[0032] Next, the medium transport path in the printer 1 will be described with reference to Fig. 2. The printer 1 is configured so that an add-on unit 6 can be connected to the bottom of the device main body 2, and Fig. 2 shows the state in which the add-on unit 6 is connected. The device main body 2 is provided with a first media cassette 3 for storing media at the bottom, and when an extension unit 6 is connected, a second media cassette 4 and a third media cassette 5 are provided further below that.

[0033] A pick roller that feeds the stored medium in the -X direction is provided for each medium cassette. Pick rollers 21, 22, and 23 are provided for the first medium cassette 3, the second medium cassette 4, and the third medium cassette 5, respectively. Further, a pair of feed rollers is provided for each medium cassette, which feeds the medium sent in the -X direction in an upward diagonal direction. Feed roller pairs 25, 26, and 27 are provided for the first medium cassette 3, the second medium cassette 4, and the third medium cassette 5, respectively. In the following, unless otherwise specified, a "roller pair" is defined as consisting of a drive roller driven by a motor (not shown) and a driven roller that rotates in contact with the drive roller.

[0034] The medium sent out from the third media cassette 5 is sent to the reversing roller 39 by the transport roller pair 29, 28. The medium sent out from the second media cassette 4 is sent to the reversing roller 39 by the transport roller pair 28. The medium is nipped between the reversing roller 39 and the driven roller 40, and sent to the transport roller pair 31. The medium sent out from the first medium cassette 3 is sent to the transport roller pair 31 without passing through the reversing roller 39 . The supply roller 19 and separation roller 20 provided near the reversing roller 39 are a pair of rollers that feed the medium from a supply tray not shown in FIG.

[0035] The medium receiving the feeding force from the transport roller pair 31 is sent between the line head 51, which is an example of a recording head, and the transport belt 13, that is, to a recording position facing the line head 51. Note that hereinafter, the medium transport path from the transport roller pair 31 to the transport roller pair 32 is referred to as a transport path T1 during recording.

[0036] The line head 51 constitutes the head unit 50. The line head 51 performs recording by ejecting ink, which is an example of liquid, onto the surface of the medium. The line head 51 is an ink ejection head configured so that the nozzles that eject ink cover the entire area in the width direction of the medium, and is configured as an ink ejection head that can perform recording over the entire width of the medium without moving in the width direction of the medium. However, the ink ejection head is not limited to this, and may be a type that is mounted on a carriage and ejects ink while moving in the width direction of the medium.

[0037] The head unit 50 is provided so as to be able to advance and retreat with respect to the transport path T1 during recording, and is provided so as to be displaceable between a recording position shown by a solid line in Fig. 2 and a retracted position where it is retracted furthest from the transport belt 13 as shown by a two-dot chain line and reference symbol 50-1 in Fig. 2. When the head unit 50 is in the retracted position, maintenance of the line head 51 is performed by a maintenance means (not shown). In this embodiment, the displacement direction of the head unit 50 is the V-axis direction along the inclination of the discharge tray 8. The head unit 50 is located below the discharge tray 8 and upstream in the medium discharge direction, and displaces along the lower surface 8e of the discharge tray 8.

[0038] Reference numerals 61, 62, 63, and 64 denote ink storage units serving as liquid storage units. Ink to be ejected from the line head 51 is supplied from each ink storage unit to the line head 51 via a tube (not shown). Each ink storage unit is provided so as to be detachable. Reference numeral 11 denotes a waste liquid storage section that stores ink as waste liquid discharged from the line head 51 toward a flushing cap (not shown) for maintenance purposes.

[0039] The conveyor belt 13 is an endless belt that is wound around pulleys 14 and 15, and rotates when at least one of the pulleys 14 and 15 is driven by a motor (not shown). The medium is conveyed to a position facing the line head 51 while being attracted to the belt surface of the conveyor belt 13. The medium can be attracted to the conveyor belt 13 by a known attraction method such as an air suction method or an electrostatic attraction method.

[0040] Here, the transport path T1 during recording, which passes through a position facing the line head 51, is configured to transport the medium upward at an angle to the horizontal and vertical directions. This upward transport direction is a direction that includes a -X direction component and a +Z direction component in Figure 1, and this configuration makes it possible to reduce the horizontal dimension of the printer 1. In this embodiment, the recording transport path T2 is set at an inclination angle in the range of 65° to 85° with respect to the horizontal direction, and more specifically, is set at an inclination angle of approximately 75°.

[0041] The medium on whose first side recording has been performed by the line head 51 is then conveyed further upward by a pair of conveyor rollers 32 positioned downstream of the conveyor belt 13. A flap 41 is provided downstream of the transport roller pair 32, and the transport direction of the medium is switched by this flap 41. When the medium is to be discharged as is, the transport path of the medium is switched by the flap 41 to face the upper transport roller pair 35, and the medium is discharged by the transport roller pair 35 toward the discharge tray 8.

[0042] When recording is to be performed on the second side of the medium in addition to the first side, the transport direction of the medium is directed to branch position K1 by flap 41. The medium then passes through branch position K1 and enters switchback path T2. In this embodiment, switchback path T2 is the medium transport path above branch position K1. A pair of transport rollers 36, 37 is provided on switchback path T2. The medium that enters switchback path T2 is transported upward by the pair of transport rollers 36, 37, and when the bottom edge of the medium passes branch position K1, the rotation direction of the pair of transport rollers 36, 37 is switched, thereby transporting the medium downward.

[0043] The switchback path T2 is connected to a reversing path T3. In this embodiment, the reversing path T3 is a medium transport path that extends from the branch position K1 to a reversing roller 39 through a pair of transport rollers 33 and 34. The medium conveyed downward from the branch position K1 receives a feeding force from the pair of conveying rollers 33 and 34 and reaches the reversing roller 39, where it is curved and reversed by the reversing roller 39 and conveyed toward the pair of conveying rollers 31.

[0044] The medium is again sent to a position facing the line head 51, and the second side, which is opposite to the first side on which recording has already been performed, faces the line head 51. This makes it possible for the line head 51 to record on the second side of the medium.

[0045] Next, a description will be given of a means for cooling the head unit 50. As described above, the air intake port 45 is formed at the downstream end of the discharge tray 8 in the medium discharge direction, and as described with reference to Figure 1, air taken in from the air intake port 45 passes through the flow paths Fa, Fb, and Fc, and is exhausted from the exhaust port 46 as shown by the arrow Fd. The flow path Fa is a flow path along the lower surface 8e of the discharge tray 8 as shown in FIGS.

[0046] 4 and 5, flow path Fb is a flow path parallel to the Y-axis direction that passes through the inside of head unit 50. More specifically, as shown in Fig. 7, head unit 50 has head control board 52 in the +V direction relative to line head 51, and further has a heat sink 53 in the +V direction relative to head control board 52. Heat sink 53 is an example of a heat dissipation member, and in particular dissipates heat generated in head control board 52, which is a heat-generating part of head unit 50.

[0047] The heat sink 53 has many fins and extends along the Y-axis direction as shown in Fig. 6. The head unit 50 has a cover member 54 that covers the heat sink 53 as also shown in Fig. 5, and an opening 54a for taking in air is formed at the end of the cover member 54 in the +Y direction.

[0048] An intake guide 48 is provided at the end in the -Y direction, which is the opposite direction to the +Y direction in which the opening 54a is formed, and a suction fan 47 is connected to an air passage 48a formed in the intake guide 48. The suction fan 47 generates negative pressure in the air passage 48a and, by extension, inside the head unit 50, which causes air to be taken in from the intake port 45. The taken-in air then passes through the flow path Fa to reach the opening 54a of the head unit 50, is taken into the head unit 50 from the opening 54a, and passes through the flow path Fa to reach the suction fan 47.

[0049] An exhaust guide 49 is provided above the suction fan 47 as shown in FIG. 5. The air exhausted from the suction fan 47 is guided in the +Z direction by the exhaust guide 49 and then exhausted in the direction of the arrow Fd as shown in FIG. 1.

[0050] As described above, an air flow path Fa for cooling the head unit 50, which is an example of an object to be cooled, is formed along the underside 8e of the discharge tray 8, so there is no need to secure additional space inside the device for air to flow horizontally, resulting in improved design freedom and also preventing the device from becoming larger in height. In this embodiment, the cooling target is the head unit 50, which is an example of a heat generating part, but the cooling target is not limited to this, and may be other heat generating parts such as a main board, a power supply unit, etc. Also, the cooling target is not limited to one, and may be multiple.

[0051] In addition, in this embodiment, the air flow path for cooling the head unit 50 includes a flow path Fa that runs from an intake port 45 formed at the downstream end of the discharge tray 8 in the medium discharge direction toward the head unit 50 along the underside 8e of the discharge tray 8. Of course, the exhaust port 46 in this embodiment may be an intake port and the intake port 45 may be an exhaust port, so that the air flow is reversed from that in this embodiment.

[0052] Furthermore, the discharge tray 8 is formed with a protruding portion 8a that protrudes upward along the media discharge direction, and as shown in Fig. 3, a part of the intake port 45 is formed in the protruding portion 8a. This makes it possible to prevent the discharge tray 8 from becoming larger due to the provision of the intake port 45, and thus to prevent the device from becoming larger. The intake port 45 can also be formed only in the formation range Wa of the protruding portion 8a.

[0053] The discharge tray 8 also includes a first portion 8c extending from the protruding portion 8a in the +Y direction and a second portion 8d extending from the protruding portion 8a in the -Y direction, with the first portion 8c forming a surface higher than the second portion 8d, and the intake port 45 extending from the protruding portion 8a in the +Y direction using the first portion 8c. That is, the intake port 45 is formed not only in the formation range Wa using the protruding portion 8a, but also in the formation range Wb of the first portion 8c. This allows the intake port 45 to be formed over a wider range, improving intake efficiency.

[0054] In addition, since the air that has passed through the head unit 50 is exhausted from the exhaust port 46 located above the discharge tray 8 as described with reference to Figure 1, there is little risk of hot air exhausted from the exhaust port 46 being taken in through the intake port 45, and an appropriate cooling effect can be obtained.

[0055] In addition, since the intake port 45 and the exhaust port 46 are provided at positions spaced apart in the horizontal direction, the risk of hot air exhausted from the exhaust port 46 being taken in through the intake port 45 can be further reduced.

[0056] The head unit 50 extends in the Y-axis direction, i.e., the medium width direction, and includes a heat sink 53 extending in the medium width direction, and the air that reaches the head unit 50 through the flow path Fa is taken into the head unit 50 and flows in the medium width direction along the heat sink 53 (flow path Fb). This makes it possible to improve the efficiency of heat dissipation from the heat sink 53.

[0057] Furthermore, the air that reaches the head unit 50 through the flow path Fa is taken into the head unit 50 from the opening 54a, and it is also preferable to arrange at least a part of the opening 54a so as to overlap with the intake port 45 in the normal direction to the support surface 8b of the discharge tray 8, i.e., in the F-axis direction. In Fig. 7, the range H1 is the range that overlaps with the intake port 45 in the F-axis direction. By positioning the opening 54a so that at least a portion of it is included in the range H1, the air taken in through the air intake 45 flows straight along the underside of the discharge tray 8 toward the opening 54a, improving the efficiency of air intake through the opening 54a.

[0058] In addition, the head unit 50 is arranged so that it can move forward and backward relative to the medium transport path opposite the line head 51 by moving along the underside 8e of the discharge tray 8, so that the space required for the head unit 50 to move forward and backward can be reduced, and the size of the device can be prevented from increasing. Furthermore, since the head unit 50 can be prevented from moving away from the flow path Fa in the F-axis direction, the head unit 50 can be efficiently cooled regardless of the position of the head unit 50.

[0059] 7, ink containing sections 61, 62, 63, and 64 that contain ink ejected from the line head 51 are provided below the discharge tray 8, and the flow path Fa faces the containing space D that contains the ink containing sections 61, 62, 63, and 64. This makes it possible to use a part of the containing space D as the flow path Fa, thereby preventing the device from becoming large in size.

[0060] Also, in FIG. 7, reference numeral 65 denotes a mounting portion for mounting the ink containing portion 61. Similarly, reference numerals 66, 67, and 68 denote mounting portions corresponding to the ink containing portions 62, 63, and 64, respectively. Each ink containing portion is detachable from its corresponding mounting portion, and is placed in a mounted state by moving in the -Z direction, which is a direction in which the ink containing portion is retracted from the flow path Fa. In FIG. 7, the two-dot chain line indicated by reference numeral 61-1 denotes the ink containing portion 61 before movement. Similarly, the two-dot chain line indicated by reference numeral 62-1 denotes the ink containing portion 62 before movement, the two-dot chain line indicated by reference numeral 63-1 denotes the ink containing portion 63 before movement, and the two-dot chain line indicated by reference numeral 64-1 denotes the ink containing portion 64 before movement. The user can place each ink containing portion in a mounted state by pushing it downward, i.e., in the -Z direction, relative to each mounting portion. In other words, space is provided above each ink storage unit for attaching and detaching the ink storage unit, and since the flow path Fa faces this space, when each ink storage unit is attached, the flow path Fa expands in the Z-axis direction, thereby making it possible to cool the head unit 50 more efficiently.

[0061] In addition, a wall portion 70 for partitioning the storage space D is provided in the -X direction with respect to the storage space D, and a wall portion 71 for partitioning the storage space D is provided in the +Z direction with respect to the storage space D. Here, the wall portion 71 is provided extending along the X-axis direction, and the wall portion 71 has the effect of straightening the air flowing through the flow path Fa. Furthermore, since the wall portion 70 extends in the Z-axis direction so as to obstruct the flow path Fa, it is also preferable to form a hole in the wall portion 70 and configure it so that the air flowing through the flow path Fa passes through the wall portion 70 in the -X direction.
