Description of the Related Art Some recording devices, such as facsimiles and printers, are provided with a path for reversing a recording medium, such as recording paper, in order to perform recording on both sides of the recording medium. The inkjet recording device described in Patent Document 1 includes a first cassette and a second cassette for storing recording media, and a recording medium fed from either cassette is sent to a position facing the recording head located above each cassette, where recording is performed on the first side. After recording on the first side, the recording medium is transported vertically upward and then vertically downward, i.e., switched back, and sent to an inversion path for inversion. After being inverted in the inversion path so that the conveyance direction changes from downward to upward, the recording medium is again sent to a position facing the recording head, where recording is performed on the second side.

[0003] [Patent Document 1] Japanese Patent Publication No. 2019-14253 Summary of the Invention [Problem to be solved by the invention]

[0004] The longer the path length of the reversing path for reversing the recording medium, the more advantages there are, such as the ability to accommodate longer recording media and the ability to ensure drying time. However, in order to lengthen the reversing path for reversing the recording medium in the path layout described in Patent Document 1, it is necessary to move vertically upward a structure disposed vertically above the reversing path, or to move vertically downward a structure disposed vertically below the curved path portion that reverses the recording medium so that the conveyance direction changes from downward to upward, which increases the height dimension of the device. [Means for solving the problem]

[0005] In order to solve the above problem, the recording device of the present invention comprises a recording unit that records on a medium, at least one medium storage unit that is located vertically below the recording unit and stores the medium before recording, a supply path that reverses the medium fed from the medium storage unit via a first curved path that is convex upward into a conveying direction that includes a component in the opposite direction to the medium feed direction from the medium storage unit, and a reversal path that transports the medium that has passed a position opposite the recording unit in a conveying direction that includes a vertically downward component and reverses it via a second curved path that is convex downward into a conveying direction that includes a vertically upward component, and is characterized in that the supply path merges with the reversal path and at least a portion of the first curved path and at least a portion of the second curved path overlap when viewed horizontally. [Brief explanation of the drawings]

[0007] The present invention will be briefly described below. A recording device according to a first aspect includes a recording unit that records on a medium, at least one medium storage unit that is located vertically below the recording unit and stores the medium before recording, a supply path that reverses the medium fed from the medium storage unit via a first curved path that is convex upward into a conveying direction that includes a component in the opposite direction to the medium feed direction from the medium storage unit, and a reversal path that transports the medium that has passed a position opposite the recording unit in a conveying direction that includes a vertically downward component and reverses the medium via a second curved path that is convex downward into a conveying direction that includes a vertically upward component, and is characterized in that the supply path merges with the reversal path and at least a portion of the first curved path and at least a portion of the second curved path overlap when viewed horizontally.

[0008] According to this aspect, the supply path merges with the inversion path, and at least a portion of the first curved path and at least a portion of the second curved path overlap when viewed horizontally, so that even if the first curved path is positioned further downward to ensure the path length of the inversion path, the height dimension of the device can be reduced.

[0009] A second aspect is the first aspect, characterized in that the curvature of the second curved path is smaller than the curvature of the first curved path. According to this aspect, since the curvature of the second curved path is smaller than the curvature of the first curved path, the medium can be curved more gently when curved along the second curved path, i.e., when a medium with recording on its first side is curved, than when curved along the first curved path, i.e., when a medium with recording on its first side is curved. In other words, when a medium with recording on it is curved, the medium is curved more gently, so damage such as wrinkles is less likely to occur in the medium, and better recording results can be obtained.

[0010] A third aspect is characterized in that, in the first or second aspect, the recording unit is composed of a liquid ejection head that ejects liquid onto a medium, and has a liquid storage section that stores the liquid ejected from the liquid ejection head between the liquid ejection head and the medium storage section in the vertical direction, and at least a portion of the liquid storage section, at least a portion of the first curved path, and at least a portion of the second curved path overlap when viewed horizontally.

[0011] According to this aspect, at least a portion of the liquid storage portion, at least a portion of the first curved path, and at least a portion of the second curved path are configured to overlap when viewed horizontally, thereby making it possible to reduce the height dimension of the device.

[0012] The fourth aspect is characterized in that, in any of the first to third aspects, the transport path passing through a position opposite the recording unit is angled with respect to the horizontal and vertical directions and transports the medium upward. According to this aspect, the transport path passing through the position facing the recording unit is angled with respect to the horizontal and vertical directions, and transports the medium upward, so that the horizontal dimension of the device can be reduced.

[0013] A fifth aspect is characterized in that, in any of the first to fourth aspects, a downward conveying path in the inversion path, which is upstream of the second curved path and conveys the medium in a conveying direction that includes a vertically downward component, is inclined in a direction from the outer surface of the device toward the center of the device, and is provided above the first curved path in the vertical direction with a supply roller that sends the medium into the inside of the device via a supply tray that protrudes from the side of the device to the outside, and at least a portion of the downward conveying path and at least a portion of the supply roller overlap when viewed vertically.

[0014] According to this aspect, the downward transport path is inclined, and at least a portion of the supply roller is inserted into a space formed by the inclination, so that the horizontal dimension of the device can be reduced.

[0015] A sixth aspect is the fifth aspect, characterized in that the medium fed into the inside of the device through the supply tray enters the reversing path. According to this aspect, in a configuration in which the medium fed into the inside of the device via the supply tray enters the reversing path, the effects of the fifth aspect described above can be obtained.

[0016] 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 as printer 1. The XYZ coordinate system shown in each figure is a Cartesian coordinate system, with the Y axis direction being the width direction that intersects with the media transport direction and also the depth direction of the device. 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, i.e., 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 will be referred to as "downstream," and the opposite direction will be referred to as "upstream." In each diagram, 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.

[0017] The printer 1 has multiple media cassettes arranged vertically at the bottom of the device main body 2. In this embodiment, the media cassettes are arranged in order from the top, the first media cassette 3, downwards, as follows: second media cassette 4, third media cassette 5, and fourth media cassette 6. The symbol P indicates the media stored in each media cassette. Each media cassette is an example of a media storage section.

[0018] Each media cassette is provided with a pick roller that feeds the stored media in the -X direction. Pick roller 21 is provided for first media cassette 3, pick roller 22 is provided for second media cassette 4, pick roller 23 is provided for third media cassette 5, and pick roller 24 is provided for fourth media cassette 6.

[0019] Each medium cassette is provided with a pair of feed rollers that feeds the medium sent in the -X direction in an upward diagonal direction that includes both a -X and +Z component. A pair of feed rollers 25 is provided for the first medium cassette 3, a pair of feed rollers 26 is provided for the second medium cassette 4, a pair of feed rollers 27 is provided for the third medium cassette 5, and a pair of feed rollers 28 is provided for the fourth medium cassette 6. In the following description, 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.

[0020] The medium fed from the first medium cassette 3 and sent diagonally upward by the feeding roller pair 25 receives a feeding force from the transport roller pair 29 and is sent diagonally upward including a +X direction component and a +Z direction component. The medium is fed from the second medium cassette 4 and sent diagonally upward by the feeding roller pair 26 , and is sent upward by the feeding force of the transport roller pair 30 until it reaches the transport roller pair 29 . The medium is sent out from the third medium cassette 5 and sent diagonally upward by the feeding roller pair 27 , and is then sent upward by the transport roller pair 31 and the transport roller pair 30 , and reaches the transport roller pair 29 . The medium is sent out from the fourth medium cassette 6 and sent diagonally upward by the feed roller pair 28 , then sent upward by the transport roller pair 32 , the transport roller pair 31 , and the transport roller pair 30 , and reaches the transport roller pair 29 . As described above, the transport roller pair 29 transports the medium in an obliquely upward direction including a +X direction component and a +Z direction component.

[0021] The media transport path downstream from the transport roller pair 29 is curved so as to be convex upward, and the media reaches the transport roller pair 30 through this curved path portion. Hereinafter, the media transport path from each media cassette until it reaches the transport roller pair 30 will be referred to as the "supply path T1." The portion of the supply path T1 that is curved so as to be convex upward between the transport roller pair 29 and the transport roller pair 30 will be referred to as the "first curved path R1." The supply path T1 reverses the media delivered from each media cassette to a transport direction that includes a +X-direction component, which is the opposite direction to the media delivery direction from each media cassette, i.e., the -X-direction. This supply path T1 then merges with the reversing path T4, described below, near the upstream side of the transport roller pair 30.

[0022] The external transport roller pair 18 shown near the transport roller pair 29 and outside the device main body 2 is a roller pair provided in an add-on unit not shown in Fig. 1. This add-on unit is configured to be able to store media, and is configured so that media sent out from a feed roller (not shown) can be supplied into the printer 1 by the external transport roller pair 18.

[0023] Also, near the first curved path R1, a supply tray 7 is provided that protrudes from the side of the device body 2 to the outside of the device. The supply tray 7 is a tray for manually feeding media, and the media is supplied from the supply tray 7 into the printer 1 by a supply roller 19 and a separation roller 20. Note that the media sent into the device via the supply tray 7 enters the supply path T1 and then the reversal path T4, which will be described later.

[0024] Next, the medium receiving the feeding force from the transport roller pair 29 passes through a curved path that is curved downward to reach the transport roller pair 31. Note that, hereinafter, the curved path that is curved downward between the transport roller pair 34 and the transport roller pair 31, which will be described later, is referred to as the "second curved path R2." The second curved path R2 is a path that constitutes the reversing path T4, which will be described later.

[0025] The medium receiving the feeding force from the transport roller pair 31 is sent to a position between the line head 12, which is an example of a recording unit and a liquid ejection head, and the transport belt 13, that is, a recording position facing the line head 12. Note that, hereinafter, the medium transport path from the transport roller pair 31 to the transport roller pair 32 is referred to as the "transport path T2 during recording." The line head 12 performs recording by ejecting ink, which is an example of a liquid, onto the surface of the medium. The line head 12 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 record across 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 of a type that is mounted on a carriage and ejects ink while moving in the width direction of the medium.

[0026] The reference numeral 10 denotes an ink storage unit serving as a liquid storage unit that stores ink. Ink ejected from the line head 12 is supplied from the ink storage unit 10 to the line head 12 via a tube (not shown). The ink storage unit 10 is composed of multiple ink tanks arranged along the X-axis direction. Reference numeral 11 denotes a waste liquid storage section that stores ink as waste liquid that is ejected from the line head 12 toward a flushing cap (not shown) for maintenance purposes.

[0027] 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 12 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.

[0028] The transport path T2 during recording, which passes through a position facing the line head 12, is configured to transport the medium upward at an angle relative to the horizontal and vertical directions. This upward transport direction 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 50° to 70° with respect to the horizontal direction, and more specifically, is set at an inclination angle of approximately 60°.

[0029] The medium on whose first side has been recorded by the line head 12 is further sent in an obliquely upward direction including a −X direction component and a +Z direction component by a pair of transport rollers 32 located downstream of the transport belt 13. A flap 41 is provided downstream of the transport roller pair 32, and this flap 41 switches the transport direction of the medium. When the medium is to be discharged as is, the flap 41 switches the transport path of the medium toward the upper transport roller pair 37. A further flap 42 is provided downstream of the transport roller pair 37, and this flap 42 switches the transport path to either discharge from discharge position A1 or transport to the transport roller pair 38 located further vertically above. When the medium is sent toward the transport roller pair 38, it is discharged from discharge position A2. The medium discharged from discharge position A1 is received by discharge tray 8, which is inclined diagonally upward including a +X direction component and a +Z direction component. The medium discharged from discharge position A2 is received by an optional tray (not shown).

[0030] When recording is to be performed on the second side of the medium in addition to the first side, the medium is sent by the flap 41 in a diagonally upward direction including a -X direction component and a +Z direction component, passes through the branch position K1, and enters the switchback path T3. In this embodiment, the switchback path T3 is the media transport path above the branch position K1. A transport roller pair 39 is provided on the switchback path T3. The medium that enters the switchback path T3 is transported upward by the transport roller pair 39, and when the rear end of the medium passes the branch position K1, the rotation direction of the transport roller pair 39 is switched, causing the medium to be transported downward.

[0031] A reverse path T4 is connected to the switchback path T3. In this embodiment, the reverse path T4 is a medium transport path that runs from the branch position K1 through the transport roller pairs 33, 34, and 30 to the transport roller pair 31. The reverse path T4 includes the second curved path R2 described above. The medium transported downward by the transport roller pair 33 receives a feeding force from the transport roller pair 33 and the transport roller pair 34, reaches the transport roller pair 30, and is again sent by the transport roller pair 30 to a position facing the line head 12. That is, the reversing path T4 is a path that transports the medium in a transport direction that includes a vertically downward component, and reverses the medium to a transport direction that includes a vertically upward component via the second curved path R2 that is convex downward.

[0032] The medium is sent again to a position facing the line head 12, with the second side, opposite to the first side on which recording has already been performed, facing the line head 12. This makes it possible to record on the second side of the medium by the line head 12. The medium with recording on the second side is discharged from the above-mentioned discharge position A1 or discharge position A2.

[0033] The configuration of the medium transport path will be further described below with reference to FIG. In Figure 2, position H1 is the upper end position of the first curved path R1 in the vertical direction, and position H2 is the lower end position of the second curved path R2 in the vertical direction. Position H1 in the vertical direction is above position H2. In other words, at least a portion of the first curved path R1 and at least a portion of the second curved path R2 overlap when viewed from the X-axis direction, which is the horizontal direction. In other words, the first curved path R1 and the second curved path R2 are configured to overlap in the vertical direction. Therefore, even if the second curved path R2 is disposed further downward in order to ensure the path length of the reversing path T4, the height dimension of the device can be reduced. In this embodiment, when viewed from the X-axis direction, a portion of the first curved path R1 and a portion of the second curved path R2 overlap, but the entire first curved path R1 may overlap a portion of the second curved path R2, or the entire second curved path R2 may overlap a portion of the first curved path R1.

[0034] Furthermore, in this embodiment, the curvature of the second curved path R2 is smaller than the curvature of the first curved path R1. This allows the medium to be curved more gently when curved along the second curved path R2 than when curved along the first curved path R1, i.e., when curving a medium on which no recording has been performed on either the first or second side. In other words, when a medium that has already been recorded on and has reduced rigidity is curved more gently, damage such as wrinkles is less likely to occur in the medium, and better recording results can be obtained.

[0035] In this embodiment, the ink containing unit 10 is located between the line head 12 and the first medium cassette 3 in the vertical direction. In FIG. 2, position H3 is the upper end position of the ink containing unit 10 in the vertical direction, and position H4 is the lower end position of the ink containing unit 10 in the vertical direction. Positions H1 and H2 are located between positions H3 and H4 in the vertical direction. In other words, at least a portion of the ink containing unit 10, at least a portion of the first curved path R1, and at least a portion of the second curved path R2 overlap when viewed from the X-axis direction, which is the horizontal direction. In other words, at least a portion of the ink containing unit 10, at least a portion of the first curved path R1, and at least a portion of the second curved path R2 are configured to overlap in the vertical direction. This configuration allows the height dimension of the device to be reduced.

[0036] Further, in the reverse path T4, a downward conveyance path T5 is located upstream of the second curved path R2 and conveys the medium in a conveyance direction that includes a vertically downward component, and is inclined in a direction from the outer surface of the device toward the center of the device. The downward conveyance path T5 is part of the reverse path T4 and is a linear path that extends from the vicinity of the upstream side of the conveyance roller pair 33 to the conveyance roller pair 34. Because this linear downward transport path T5 is inclined, a space is formed below the downward transport path T5. The supply roller 19 fits into this space. In FIG. 2, position W1 is the end position of the supply roller 19 in the -X direction, and position W2 is the end position of the supply roller 19 in the +X direction. As is clear from FIG. 2, at least a portion of the downward transport path T5 and at least a portion of the supply roller 19 overlap when viewed vertically. In other words, at least a portion of the downward transport path T5 and at least a portion of the supply roller 19 overlap in the horizontal direction. This configuration allows the horizontal dimension of the device to be reduced. In this embodiment, a portion of the downward conveying path T5 overlaps with a portion of the supply roller 19 when viewed vertically, but the entire downward conveying path T5 may overlap with a portion of the supply roller 19, or the entire supply roller 19 may overlap with a portion of the downward conveying path T5.

[0037] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these modifications are also included in the scope of the present invention. For example, in this embodiment, the transport path T2 during printing is inclined upward, but it may be along the vertical direction or along the horizontal direction. Furthermore, in this embodiment, the downward transport path T5 is inclined downward, but it may be along the vertical direction if overlap with the supply roller 19 in the horizontal direction is not taken into consideration. Furthermore, the means for supplying the medium via the supply tray 7 and the means for supplying the medium from the expansion unit using the external transport roller pair 18 may be omitted. Furthermore, the medium supplied from the supply tray 7 into the printer 1 by the supply roller 19 and separation roller 20 may be configured to enter the reversal path T4 as shown in Fig. 3. By configuring it in this way, the supply tray indicated by reference numeral 7A, the supply roller indicated by reference numeral 19A, and the separation roller indicated by reference numeral 20A in Fig. 3 can be arranged further vertically above. This means that the degree of freedom in the placement of the supply tray, supply roller, and separation roller can be improved. [Explanation of symbols]
