[0007] The present disclosure will be described below based on embodiments. The liquid ejection device 10 is, for example, a multifunction peripheral. The liquid ejection device 10 has multiple functions including a scanning function, a copying function, and a printing function. The liquid ejection device 10 may also have a facsimile function.

[0008] In each drawing, the same components are denoted by the same reference numerals, and redundant explanations are omitted. In this specification, the terms "same," "identical," and "simultaneous" not only refer to being completely the same, but also include being the same taking into account measurement errors, being the same taking into account manufacturing variations in components, and being the same to the extent that functionality is not impaired. For example, "their dimensions are the same" means that, taking into account measurement errors and manufacturing variations in components, the difference in dimensions between the two components is within ±10 percent of one dimension, more preferably within ±5 percent, and particularly preferably within ±3 percent.

[0009] In each figure, the liquid ejection device 10 is placed on a horizontal installation surface. Of the Z axis that is perpendicular to the installation surface of the liquid ejection device 10, the side of the liquid ejection device 10 relative to the installation surface is defined as the +Z direction side, and the opposite side is defined as the -Z direction side, and the two axes that are perpendicular to the Z axis are defined as the X axis and Y axis, respectively. Furthermore, the directions parallel to the X axis, Y axis, and Z axis are defined as the X axis direction, Y axis direction, and Z axis direction, respectively. The X-axis direction includes both the +X and -X directions, the Y-axis direction includes both the +Y and -Y directions, and the Z-axis direction includes both the +Z and -Z directions.

[0010] The X-axis direction is the depth direction when the liquid ejection device 10 is viewed from the front. The X-axis direction is the width direction of the medium M. The X-axis direction is the width direction of the recording unit 20, which will be described later. The front of the liquid ejection device 10 is the side on which the operation unit 14, which the user operates to give instructions to the liquid ejection device 10, is located.

[0011] 1. Embodiment 1 1, the liquid ejection device 10 is, for example, a multifunction peripheral. The liquid ejection device 10 includes a rectangular parallelepiped device main body 11. The liquid ejection device 10 includes a printing unit 12 configured by the device main body 11, and an image reading unit 13 disposed above the printing unit 12. The device main body 11 has a transport path T (see FIG. 2) along which a medium M such as paper is transported.

[0012] Image reading unit 13 is configured to be able to read an image of original document D. Image reading unit 13 includes reading unit 13A that reads original document D, and automatic document feeder 13B that is arranged above reading unit 13A. Automatic document feeder 13B feeds original document D placed on document tray 13C to reading unit 13A. Reading unit 13A reads original document D and discharges the read original document D to discharge tray 13D. Reading unit 13A also has a flatbed reading function that reads original document D set on a document table that is exposed when automatic document feeder 13B, which also serves as a document table cover, is opened.

[0013] The liquid ejection device 10 has an operation unit 14 on the device body 11. The operation unit 14 has a display unit 14A made up of a touch panel. A user can give instructions to the liquid ejection device 10 by touching the display unit 14A. The operation unit 14 may also have an operation button.

[0014] The liquid ejection device 10 is equipped with cassettes 15 that can store multiple media M. The cassettes 15 may be provided in one or multiple stages, for example, four stages. The cassettes 15 are inserted into the lower part of the device main body 11 in a detachable state by sliding in the X-axis direction. The multiple cassettes 15 store, for example, media M of different sizes or types. The cassettes 15 have handles 15A that the user can hook with their fingers when pulling out the cassettes 15.

[0015] The liquid ejection device 10 includes a front frame 11A at the end of the base frame in the +X direction, and a rear frame 11B at the end of the base frame in the -X direction, as a base frame. The front frame 11A and the rear frame 11B are formed of a metal material. A motion unit 30 (described later) is fixed to the front frame 11A and the rear frame 11B to form the base of the liquid ejection device 10. An exterior member is attached to the base of the liquid ejection device 10 to form the housing of the liquid ejection device 10.

[0016] The liquid ejection device 10 includes a first door 16 and multiple cover doors 17 on the side surface of the device body 11 on the -Y direction side. The first door 16 and the cover door 17 form part of an exterior member. The first door 16 and the cover door 17 can be opened and closed between an open state that exposes the transport path T (see FIG. 2) and a closed state that covers the transport path T. The first door 16 and the cover door 17 have handles 16A and 17A that allow the user to open and close them. The first door 16 includes a feed tray 16T on which the medium M can be placed. The feed tray 16T is attached to the first door 16 so as to be openable and closable. The feed tray 16T has a handle 16B that allows the user to open and close it.

[0017] As shown in FIGS. 1 and 2, the liquid ejection device 10 has a recording unit 20 in a device main body 11 that records on a medium M (see FIG. 2). The recording unit 20 records on, for example, a medium M fed from a cassette 15 and a medium M fed from a feed tray 16T. A liquid storage unit 98 (see FIG. 2) that stores ink, which is an example of a liquid, is housed within the device main body 11. The recording unit 20 records on the medium M using a liquid such as ink supplied from the liquid storage unit 98.

[0018] The liquid ejection device 10 has a second door 18D on the side surface on the +X direction side of the device body 11. The second door 18D constitutes a part of the exterior member. The second door 18D can be in an open state (see FIG. 14) that allows access to the liquid storage section 98, a waste liquid storage section 99 described below, a storage section 600 described below, or a regulating member 500 stored in the storage section 600, or a closed state (see FIG. 1) that covers the liquid storage section 98, the waste liquid storage section 99, the storage section 600, or the regulating member 500 stored in the storage section 600. The closed state of the second door 18D can also be said to be a state in which access to the liquid storage section 98, the waste liquid storage section 99, the storage section 600, or the regulating member 500 stored in the storage section 600 is not possible.

[0019] The liquid ejection device 10 includes a discharge unit 19 between the device body 11 and the image reading unit 13 . The discharge unit 19 has a discharge tray 19A that forms its bottom. The discharge tray 19A is a plate-shaped member and has a loading surface 19B on which the discharged medium M is placed. The discharge tray 19A is inclined at a predetermined angle so that the downstream side of the discharge direction in which the medium M is discharged after recording is higher than the upstream side. Furthermore, the discharge tray 19A is located in the +Z direction of the recording unit 20 in the Z direction.

[0020] As shown in FIG. 2, the liquid ejection device 10 includes a transport path T along which a medium M to be recorded by the recording unit 20 is transported. Note that FIG. 2 shows a simplified view of each component of the liquid ejection device 10. The medium M is transported through the transport path T indicated by the dashed line in FIG. 2. The AB coordinate system shown on the YZ plane is an orthogonal coordinate system. The A direction is a direction that intersects with the X-axis direction. The A direction is the transport direction of the medium M in the region of the transport path T that faces the recording head 20H of the recording unit 20. The upstream direction of the A direction is referred to as the -A direction, and the downstream direction is referred to as the +A direction.

[0021] In this embodiment, the A direction is inclined so that the +A direction is closer to the +Z direction than the -A direction. Specifically, it is inclined in the range of 50° to 70° with respect to the horizontal direction, and more specifically, it is inclined at approximately 60°. In this way, at the recording position PH4 where recording is performed by the recording unit 20, the transport direction of the medium M is inclined so as to intersect both the horizontal direction and the Z-axis direction.

[0022] A transport path T1 extending from an external device and a transport path T2 extending from a feed tray 16T provided in the device body 11 converge at the transport path T. As shown in FIGS. 2, 12, and 13, the liquid ejection device 10 includes a transport path forming member 105 at the position where the transport paths T1 and T2 converge. As shown in FIGS. 12 and 13, the transport path forming member 105 is disposed on the +Z direction side of a frame 121 extending in the X-axis direction. The frame 121 is disposed in the device body 11 and is a plate-shaped metal member that connects the front frame 11A and the rear frame 11B.

[0023] A storage section 300 that stores a restricting member 200, which will be described later, is disposed in the frame 121. From this, it can be said that the first door 16 can be in an open state that allows access to the storage section 300, and a closed state that makes the storage section 300 inaccessible.

[0024] The transport path forming member 105 is disposed in the device body 11 so as to be rotatable about a rotation axis (not shown) along the X-axis direction. The transport path forming member 105 is displaceable between a transport position TP when the first door 16 is in a closed state and a separated position SP when the first door 16 is in an open state.

[0025] 2, the transport position TP is a position where the transport path forming member 105 is located along the transport path T and can transport the medium M. The transport path forming member 105 at the transport position TP does not cover the storage section 300 or the regulating member 200 stored in the storage section 300.

[0026] The separated position SP is a position away from the transport position TP in the -Z direction. As shown in FIG. 12, the transport path forming member 105 at the separated position SP covers the storage unit 300 or the regulating member 200 stored in the storage unit 300. Therefore, when the first door 16 is opened, the transport path forming member 105 is located at the separated position SP. Therefore, the regulating member 200 stored in the storage unit 300 is not visible when the first door 16 is opened. For example, when a service technician needs to access the storage unit 300 or the regulating member 200 stored in the storage unit 300, the first door 16 is opened, and the transport path forming member 105 is displaced from the separated position SP to a position where it does not cover the storage unit 300 or the regulating member 200, for example, the transport position TP, as shown in FIG.

[0027] As shown in FIG. 2, along the transport path T, there are arranged a plurality of pickup rollers 21 that transport the medium M stored in a plurality of cassettes 15, a plurality of transport roller pairs 22, 23, and 26, a transport unit 25, a plurality of flaps 27, and a sensor SE4 that detects the width of the medium M in the X direction. The transport unit 25 supports a portion of the medium M that is in a recording position facing the recording unit 20 and transports the medium M. The flap 27 has the function of switching the path along which the medium M is transported. The pickup roller 21 is driven by a feed motor (not shown). Furthermore, the transport roller pairs 22, 23, and 26 and the transport unit 25 are driven by one or more transport motors (not shown).

[0028] The transport path T forms a curved portion in the area facing the sensor SE4, and extends in the direction A in the area downstream of this curved portion. On the transport path T, downstream of the transport unit 25, there are provided transport paths T3 and T4 leading to the discharge section 19, and a reversing path T5 that turns the medium M over. A discharge tray (not shown) is provided in the discharge section 19 in line with the transport path T4. When double-sided recording is performed, the medium M that has completed recording on its first side is transported into the reversing path T5 before recording on its second side. The medium M is reversed at the reversing path T5, and, as with recording on the first side, is sent back to the recording position via the transport path T, where recording on the second side is performed.

[0029] The transport unit 25 supports the medium M during transport. The transport unit 25 has two pulleys 25A and an endless transport belt 25B wound around the two pulleys 25A. The medium M is transported to a position facing the recording unit 20 while being attracted to the belt surface of the transport belt 25B. Methods for attracting the medium M to the transport belt 25B include air suction and electrostatic attraction. In this way, the transport belt 25B supports the medium M while attracting it. The transport unit 25 is disposed opposite the recording unit 20 in the B direction.

[0030] The recording unit 20 moves in the direction B, which is the direction facing the transport unit 25. The recording unit 20 of this embodiment moves back and forth in the direction B, which is inclined at a predetermined angle with respect to the horizontal plane. The recording unit 20 is an example of a moving unit MP that can move in the direction B. The direction B is an example of a moving direction MD in which the recording unit 20 moves. The direction B is the moving direction when the recording unit 20 moves forward and backward relative to the transport unit 25. In the direction B, the direction in which the recording head 20H approaches the transport path T is called the +B direction, and the direction in which it moves away from the transport path T is called the -B direction. The -B direction is the direction in which the recording head 20H moves diagonally upward along the direction in which it moves away from the transport unit 25.

[0031] The B direction is a direction in which the recording unit 20 is displaced, and is a direction that includes a component of the Z direction, which is the height direction. In this embodiment, the B direction is inclined so that the -B direction is closer to the +Z direction than the +B direction, and is perpendicular to the A direction. The B direction also intersects with the X-axis direction.

[0032] The recording unit 20 is configured to be movable between a retracted position PH1, indicated by a two-dot chain line in FIG. 2, and a recording position PH4, indicated by a solid line in FIG. 2. By moving in the direction B, the recording unit 20 can be moved to a plurality of positions including at least the retracted position PH1 and the recording position PH4. The movement direction of the recording unit 20 is accompanied by displacement of the recording unit 20 in the Z-axis direction, and is also referred to as the lifting / lowering direction, since this movement involves both upward and downward movement. Note that the movement direction of the recording unit 20 is not limited to a direction forming a predetermined angle with respect to the horizontal, but may also be the horizontal direction or the Z-axis direction.

[0033] In this embodiment, the recording unit 20 rises in the -B direction and falls in the +B direction. The B direction is perpendicular to the nozzle surface 20N. In other words, the direction perpendicular to the nozzle surface 20N, which is the surface where the nozzles N (see FIG. 9) of the recording head 20H open, is the direction in which the recording head 20H rises and falls.

[0034] When the recording unit 20 is at recording position PH4, the recording head 20H ejects liquid such as ink onto the portion of the medium M supported by the transport unit 25. In this way, the recording unit 20 records information such as an image on the medium M. The liquid ejection device 10 is equipped with a sensor SE1 that can detect the recording unit 20 at the retracted position PH1. The sensor SE1 is configured to be able to detect the recording unit 20 when it is at the retracted position PH1. The retracted position PH1 detected by the sensor SE1 is also the origin position when measuring the position of the recording unit 20 on the movement path.

[0035] The recording unit 20 has a recording head 20H that ejects ink, which is an example of a liquid. The recording head 20H is disposed opposite the transport unit 25 in the B direction at a recording position PH4, and records information on the medium M by ejecting ink from the recording head 20H. The recording unit 20 is a line head configured so that the recording head 20H that ejects ink covers the entire area in the X-axis direction, which is the width direction of the medium M.

[0036] Furthermore, the recording unit 20 records using a line recording method that allows recording across the entire width of the medium M without movement in the X-axis direction, which is the width direction of the medium M. The X-axis direction is an example of the width direction of the medium M, and is also an example of the width direction of the recording unit 20. However, the recording unit 20 is not limited to this, and may also be a serial recording type that is mounted on a carriage and ejects ink while moving in the X-axis direction. In other words, as long as the liquid ejection device 10 is configured to include the first maintenance unit 60, the recording unit 20 may use either recording method.

[0037] The liquid ejection device 10 is provided with a first maintenance unit 60 in the device body 11 that performs maintenance on the nozzle surface 20N of the recording unit 20. As shown in FIGS. 5 to 8, the first maintenance unit 60 is movable between a capping position PC2 (see FIG. 8) and a non-capping position PC1 (see FIG. 5) that is retracted from the capping position PC2 in the -A direction. The recording unit 20 is movable to a maintenance position PH3 (see FIG. 8) that is a predetermined distance away from the recording position PH4 in the -B direction. The first maintenance unit 60 performs maintenance on the recording head 20H that is in the maintenance position PH3.

[0038] The first maintenance part 60 is configured to be movable between a non-capping position PC1 and a capping position PC2 by moving in the direction A. The first maintenance part 60 of this embodiment moves back and forth in the direction A, which is inclined at a predetermined angle with respect to the horizontal plane. The first maintenance part 60 is an example of a moving part MP that can move in the direction A. The direction A is an example of a moving direction MD in which the first maintenance part 60 moves. The first maintenance part 60 is a cap part 62, which will be described later.

[0039] The first maintenance unit 60 moves from the uncapping position PC1 in the +A direction to the capping position PC2 to perform maintenance on the recording head 20H. When the liquid ejection device 10 is in the middle of a recording operation, the first maintenance unit 60 waits at the uncapping position PC1.

[0040] The liquid ejection device 10 is equipped with a sensor SE2 capable of detecting the first maintenance part 60 at the uncapping position PC1. The sensor SE2 is configured to be able to detect the first maintenance part 60 when at the uncapping position PC1. The first maintenance part 60 is detected by the sensor SE2 when it retreats from the capping position PC2 in the -A direction. The uncapping position PC1 detected by the sensor SE2 is also the origin position when measuring the position on the movement path of the first maintenance unit 60. The maintenance performed by the first maintenance unit 60 will be described in detail later.

[0041] 2, the liquid ejection device 10 includes, within the device body 11, a control unit 95 that controls the operation of each unit of the liquid ejection device 10, a liquid storage unit 98 that stores liquid such as ink, and a waste liquid storage unit 99 that stores ink or the like as waste liquid. The liquid storage unit 98 supplies ink to the recording head 20H via a tube (not shown).

[0042] Next, the configuration of the motion unit 30 will be described. As shown in Fig. 3, the liquid ejection device 10 includes a motion unit 30 inside the device main body 11. The motion unit 30 is a unit in which a first movement mechanism 31 (see Figs. 5 to 8) that moves the recording unit 20, a second movement mechanism 70 (see Figs. 4 to 8) that moves the first maintenance unit 60, and a third movement mechanism 83 (see Figs. 10 and 11) that moves the second maintenance unit 80 are integrally assembled.

[0043] The first movement mechanism 31 moves the recording unit 20 in direction B, which intersects with the nozzle surface 20N (see FIG. 4). The nozzle surface 20N is the surface of the recording head 20H that faces the transport path T. The second movement mechanism 70 moves the first maintenance unit 60 in direction A along the nozzle surface 20N. The control unit 95 controls the operations of the first movement mechanism 31 and the second movement mechanism 70. The motion unit 30 supports the recording unit 20 to be movable in direction B, supports the first maintenance unit 60 to be movable in direction A, and further supports the second maintenance unit 80 to be movable in the X-axis direction.

[0044] That is, the first maintenance unit 60 is movable in the A direction and performs a first maintenance on the recording head 20H. The second maintenance unit 80 is movable in the X axis direction and performs a second maintenance on the recording head 20H that is different from the first maintenance. Note that although the movement direction of the second maintenance unit 80 in this embodiment is the X axis direction, it may be in a direction other than the X axis direction as long as the second maintenance can be performed without interfering with the first maintenance unit 60.

[0045] The motion unit 30 has a main body frame 33 that constitutes the main body portion. The main body frame 33 has a pair of side frames 34 that face each other at a predetermined distance in the X-axis direction, and a plurality of horizontal frames 35 that connect the pair of side frames 34.

[0046] 3, the pair of side frames 34 are configured as side plates along the AB plane. One side frame 34 is disposed on the +X direction side, and the other side frame 34 is disposed on the -X direction side. For example, the other side frame 34 is formed with a through-hole 34A through which the second maintenance part 80 moves.

[0047] A guide member 36 that guides the recording unit 20 movably in direction B is attached to each of the two opposing inner surfaces of the pair of side frames 34. The two guide members 36 are disposed approximately symmetrically with respect to the center of the main body frame 33 in the X direction.

[0048] 3 and 5, the guide member 36 has a guide rail 37 extending in the B direction, and guide rails 38 and 39 branching off from a midpoint on the guide rail 37 and extending in the Z direction. The guide rails 37, 38, and 39 are all grooved rails that open toward the center of the main body frame 33 in the X direction, and the guide rollers 29 (see FIGS. 5 to 8 and 19) of the recording unit 20 are inserted into the grooves. The guide rail 37 is an example of a guide unit that guides the recording unit 20 in the B direction.

[0049] The recording unit 20 is guided by the guide rail 37 to move to one or more positions away from the transport unit 25 with respect to the recording position PH4. Specifically, by moving along the guide rail 37, the recording unit 20 can move to multiple stop positions such as the retracted position PH1, the recording position PH4, the standby position PH2, and the maintenance position PH3.

[0050] When the recording unit 20 is in the retracted position PH1, it can be guided to replacement guide rails 38, 39. In the liquid ejection device 10, a user or an operator such as a serviceman can remove the recording unit 20 from the device body 11 for maintenance and replace it with a new one. When the user operates the operation unit 14 (see FIG. 1) to notify the liquid ejection device 10 that the recording unit 20 needs to be replaced, the control unit 95 moves the recording unit 20 to the retracted position PH1, which is also the replacement position. This allows the operator to replace the recording unit 20 through the insertion port that is exposed when the discharge tray 19A is removed.

[0051] The first maintenance unit 60 performs cleaning of the recording head 20H as the first maintenance. As shown in FIGS. 4, 8, and 9, the first maintenance unit 60 in this embodiment is a cap unit 62 that cleans the recording head 20H. The cap unit 62 has a cap 64 that can cover the nozzles N of the recording head 20H. As shown in FIGS. 8 and 9, the cap unit 62 comes into contact with the recording head 20H and, in a capping state in which the cap 64 covers the nozzles N, forcibly discharges waste liquid such as thickened ink and ink containing air bubbles from within the nozzles N. In this way, the nozzles N are cleaned by the cap unit 62. This cleaning prevents or eliminates clogging of the nozzle N.

[0052] The second maintenance unit 80 performs maintenance on the recording head 20H. As shown in Figures 10 and 11, the second maintenance unit 80 of this embodiment is a wiper unit 82 that performs wiping to wipe the nozzle surface 20N of the recording head 20H as second maintenance. The wiper unit 82 has a wiper member 81, and the wiper member 81 wipes the nozzle surface 20N of the recording head 20H.

[0053] 4, the recording head 20H is configured with a plurality of unit heads 20U lined up in the X-axis direction. The cap section 62 includes a plurality of caps 64 arranged in the X-axis direction at positions facing the plurality of unit heads 20U, and a cap holder 66 that holds the plurality of caps 64. The caps 64 are open on the -B side facing the recording head 20H.

[0054] The cap portion 62 has a pair of racks 71 fixed to both longitudinal sides of the cap holder 66, which mesh with the pinion 72. In other words, the cap portion 62 has a pair of racks 71. A plurality of guide rollers 74 are attached to both longitudinal sides of the cap holder 66. The guide rollers 74 on both sides are engaged with guide rails 73 on both sides. The guide rollers 74 rotate and are guided by the guide rails 73, allowing the cap portion 62 to move in direction A. When the cap portion 62 is in the uncapping position PC1 shown in FIG. 4, it is detected by the sensor SE2.

[0055] A pair of engagement portions 69 for positioning protrude from the cap holder 66 of the cap unit 62 at positions on both sides of the caps 64 in the X-axis direction. The pair of engagement portions 69 protrude to a position higher in the -B direction than the top surfaces of the caps 64. As the cap unit 62 moves from the uncapping position PC1 shown in FIG. 4 to the capping position PC2 in the +A direction indicated by the arrow in the figure, the pair of engagement portions 69 engage with a pair of pin portions 20G on the recording unit 20 side. This positions the cap unit 62 at the capping position PC2 (see FIG. 8) in the A direction.

[0056] Next, the movement paths and movement operations of the recording unit 20 and the cap unit 62 will be described with reference to Figures 5 to 8. Note that the second maintenance unit 80 is omitted from Figures 5 to 8.

[0057] The recording unit 20 moves in the B direction to be positioned at the recording position PH4 (see FIG. 5), the standby position PH2 (see FIG. 6), the maintenance position PH3 (see FIG. 8), and the retracted position PH1 (see FIG. 2).

[0058] The recording position PH4 is the position of the recording unit 20 when recording on the medium M. The maintenance position PH3 is the position of the recording unit 20 when the nozzle surface 20N is covered with the cap 64. That is, this is the position of the recording unit 20 when capping is performed with the cap 64. When not recording, the recording unit 20 waits while being capped with the cap 64. The standby position PH2 is located in the -B direction from the maintenance position PH3, and is a position retreated from the movement path of the cap unit 62.

[0059] The retract position PH1 is a position where the recording unit 20 performs origin search to detect the origin position on the movement path. The retract position PH1 is located on the -B direction side, where the recording unit 20 rises, from the standby position PH2. In this embodiment, the retract position PH1 is also a replacement position when replacing the recording unit 20.

[0060] 5, the liquid ejection device 10 includes a first movement mechanism 31 that moves the recording unit 20 in direction B, which intersects with the nozzle surface 20N. The first movement mechanism 31 is, for example, a rack and pinion system. In this example, the first movement mechanism 31 includes, for example, a pinion 43 that is a drive gear, a rack 28 that is arranged in the recording unit 20, and an elevation drive unit 41 that is a drive source that rotates a rotation shaft (not shown) to which the pinion 43 is attached.

[0061] The length of the rack 28 is set to be longer than the length of one revolution of the pinion 43. When the lifting / lowering drive unit 41 is driven, the recording unit 20 moves in the direction B via the first movement mechanism 31. The recording unit 20 moves in the direction B while being guided by a guide rail 37 extending in the direction B. The first movement mechanism 31 raises and lowers the recording unit 20 along the direction B.

[0062] The lifting / lowering drive unit 41 is configured, for example, with a worm gear mechanism including a worm wheel attached to a rotation shaft to which the pinion 43 is attached and a worm gear that rotates the worm wheel, and a drive motor having the worm gear attached to an output shaft. The lifting / lowering drive unit 41 in this embodiment is disposed on the −X direction side of the rear frame 11B, at a position on the +X direction side of an exterior member (not shown) that is disposed on the −X direction side of the rear frame 11B.

[0063] A plurality of guide rollers 29 made of rollers are rotatably arranged on the side of the recording unit 20. The guide rollers 29 are made of, for example, metal. The plurality of guide rollers 29 are guided by a guide rail 37, causing the recording unit 20 to move in direction B along the guide rail 37. The guide rollers 29 are an example of a guided portion guided by the guide rail 37.

[0064] The cap portion 62 is provided so as to be movable in the direction A, which is the movement direction MD of the cap portion 62. The cap portion 62 moves back and forth in the direction A while being guided by a guide rail 73 extending in the direction A.

[0065] The liquid ejection device 10 includes a second movement mechanism 70 that moves the cap portion 62 in direction A along the nozzle surface 20N. The second movement mechanism 70 is a rack and pinion system. As shown in FIGS. 4 to 9 and 19, the second movement mechanism 70 includes a rack 71 provided on the cap portion 62, rack and pinion mechanisms 70A, 70B (see FIGS. 4 and 9) with a pinion 72 serving as a drive gear, and a first slide drive unit 75 that serves as the drive source for the pinion 72. In this embodiment, the first slide drive unit 75 is disposed on the +X direction side of the front frame 11A and on the -X direction side of an exterior member (not shown) disposed on the +X direction side of the front frame 11A. For this reason, the first slide drive unit 75 is indicated by a two-dot chain line in FIGS. 5 to 8.

[0066] The rack 71 may be made of metal or may be formed of a resin material. Examples of resin materials that can be used to form the rack 71 include POM (Polyoxymethylene) and PBT (Poly Butylene Terephthalate). The length of the rack 71 is set to be longer than the length of one circumference of the pinion 72. The second moving mechanism 70 moves the cap portion 62 in the direction A in which the rack 71 extends. The first slide driving unit 75 is composed of, for example, a worm gear mechanism including a worm wheel attached to a rotating shaft 76 (see FIG. 4) to which the pinion 72 is attached and a worm gear that rotates the worm wheel, and a drive motor with the worm gear attached to its output shaft.

[0067] The cap part 62 can be moved back and forth in the direction A by the second moving mechanism 70. The cap part 62 moves to a non-capping position PC1 (see FIGS. 5 and 6) and a capping position PC2 (see FIGS. 8 and 9) where the cap part 62 faces the recording head 20H. The non-capping position PC1 is a position where the cap part 62 waits when the recording unit 20 is recording. The capping position PC2 is a position of the cap part 62 when capping is performed to cover the nozzles N opening in the nozzle surface 20N of the recording head 20H.

[0068] When capping is performed, as shown in Figure 7, in order to ensure a movement path for the cap section 62 when it moves from the non-capping position PC1 to the capping position PC2, the recording section 20 moves to a standby position PH2, which is retreated a predetermined distance in the -B direction from the recording position PH4.

[0069] As shown in FIG. 6, when the recording unit 20 is in the standby position PH2, the cap unit 62 moves in the +A direction from the uncapping position PC1 shown in FIGS. 5 and 6 to the capping position PC2 shown in FIG. 7. The cap 64 at the capping position PC2 faces the recording head 20H at the standby position PH2 in the +B direction. As the recording unit 20 moves in the +B direction from the standby position PH2, the recording head 20H and the cap 64 at the capping position PC2 come into contact with each other at a predetermined pressure. The position where the recording head 20H comes into contact with the cap 64 is the maintenance position PH3 shown in FIG. 8. The cap 64 at the capping position PC2 covers the nozzles N (see FIG. 9) of the recording head 20H at the maintenance position PH3.

[0070] As shown in FIGS. 8 and 9, when the cap portion 62 is at the capping position PC2, the cap portion 62 is separated from the transport path T along which the medium M to be recorded by the recording unit 20 is transported.

[0071] 9, the cap unit 62 performs maintenance on the recording head 20H in a capping state in which the cap 64 covers the nozzles N of the recording head 20H. The cap unit 62 creates a negative pressure inside the cap 64 in the capping state by driving a pump motor 79, which is the drive source of a pump 78 connected to the cap 64 through a pipe 77. Then, the cap unit 62 forcibly discharges liquid such as ink from the nozzles N of the recording head 20H into the cap 64.

[0072] The liquid forcibly discharged from the recording head 20H by the cap section 62, and the liquid such as ink discharged for maintenance from the recording head 20H at the standby position PH2 toward the cap 64 at the capping position PC2 (see Figure 7), are collected from the cap 64 as waste liquid in the waste liquid storage section 99 shown in Figure 2.

[0073] Next, the detailed configuration of the cap unit 62 will be described. Figure 9 shows the recording unit 20 and the cap unit 62 in a capped state. The cap unit 62 includes a cap 64 that can come into contact with the nozzle surface 20N, a cap holder 66 for holding the cap 64, and a spring 65 as an example of a biasing unit provided between the cap 64 and the cap holder 66. The spring 65 biases the cap 64 toward the nozzle surface 20N. The spring 65 biases the cap 64 in the -B direction. The cap 64 is supported by the spring 65.

[0074] 9 are arranged in the X-axis direction. The cap section 62 includes a plurality of caps 64 arranged in the X-axis direction, which is the width direction of the medium M, at positions facing the plurality of unit heads 20U. The cap 64 is open on the -B direction side facing the recording head 20H, and has a seal portion (not shown) made of a rubber-elastic material around the opening. When the cap 64 is pressed against the nozzle surface 20N of the unit head 20U by the biasing force of the spring 65, at least a portion of the seal portion is elastically compressed. The cap portion 62 presses the cap 64 against the nozzle surface 20N with a predetermined pressure due to the biasing force of the spring 65 in the -B direction and the restoring force of the elastically compressed seal portion.

[0075] The cap 64 has a shape and size that allows it to cover all of the nozzles N in the nozzle surface 20N of the unit head 20U. When the cap portion 62 is at the capping position PC2, the cap 64 is disposed at a position that faces the nozzle surface 20N of each unit head 20U in the direction B. The cap 64 comes into contact with the nozzle surface 20N of the recording head 20H with a predetermined pressure, thereby covering the multiple nozzles N that open to the nozzle surface 20N.

[0076] Covering the nozzle surface 20N with the cap 64 suppresses an increase in viscosity due to drying of liquid such as ink in the nozzles N of the recording head 20H. When the recording unit 20 moves downward from the retracted position PH1 (see FIG. 2) in direction B to a predetermined maintenance position PH3, the recording head 20H and the cap 64 come into contact with each other at a predetermined pressure, and the capping state is established.

[0077] The cap 64 is attached to the cap holder 66 via a slide portion 67 so as to be movable in the direction B relative to the cap holder 66. The elastic force of a spring 65 interposed between the bottom surface of the cap 64 and the upper surface of the cap holder 66 biases the cap 64 in the -B direction, which is the upward direction, relative to the cap holder 66. Note that the spring 65 may be an elastic member such as a tension spring or a torsion coil spring, as long as it can bias the cap 64 in the -B direction.

[0078] The second movement mechanism 70 includes a pair of rack and pinion mechanisms 70A and 70B. A pair of racks 71 constituting the rack and pinion mechanisms 70A and 70B are fixed to both side surfaces of the cap holder 66 in the X-axis direction. Pinions 72, which are a pair of drive gears constituting the rack and pinion mechanisms 70A and 70B, are rotatably disposed on the +B direction side opposite the toothed portions 71A of the pair of racks 71. The toothed portions 71A of the racks 71 mesh with the toothed portions 72A of the pinions 72. The pair of pinions 72 are attached to both ends of the rotation shaft 76 from the center. In addition, guide rollers 74, each consisting of a plurality of rollers rotatable about the X-axis direction, are provided on both side walls of the cap portion 62 in the X-axis direction. The guide rollers 74 are made of, for example, metal. The guide rollers 74 are guided along the A direction (see FIGS. 8, 19, etc.) in which a guide rail 73 with a C-shaped cross section extends.

[0079] When the rotary shaft 76 rotates due to the power of the first slide drive unit 75 (see Figures 4, 9, 19, etc.), which is the drive source of the cap unit 62, the pair of pinions 72 rotates. When the first slide drive unit 75 is driven in the forward direction, the cap unit 62 moves in the +A direction via the meshing of the pinion 72 and the rack 71. On the other hand, when the first slide drive unit 75 is driven in the reverse direction, the cap unit 62 moves in the -A direction via the meshing of the pinion 72 and the rack 71.

[0080] Next, the configuration of the wiper unit 82 will be described. As shown in Fig. 10, the wiper unit 82 is movable in the X-axis direction, which is perpendicular to the B and A directions, and performs maintenance on the recording head 20H of the recording unit 20. The wiper unit 82 includes a wiper member 81 and a slider 82A that supports the wiper member 81.

[0081] The liquid ejection device 10 includes a sensor SE3 that can detect the wiper unit 82 when it is in the retracted position PW1, and a third movement mechanism 83 that moves the wiper unit 82 back and forth in the X-axis direction. The sensor SE3 is configured to be able to detect the wiper unit 82 when it is in the retracted position PW1. The third movement mechanism 83 includes a guide rail 84 that guides the slider 82A, an endless belt 86 that is wound around a pair of pulleys 85, and a second slide motor 87 that is a drive source that rotates one of the pulleys 85.

[0082] The guide rail 84 guides the slider 82A movably along the X-axis direction. The pair of pulleys 85 are disposed at positions spaced a predetermined distance apart in the X-axis direction. The belt 86 is wound around the pair of pulleys 85, and is disposed in a state parallel to the nozzle surface 20N over a range wider than the movement range of the wiper member 81. The control unit 95 can also control the third movement mechanism 83. More specifically, the control unit 95 drives the second slide motor 87 forward and reverse to move the wiper member 81 back and forth along a path from the retracted position PW1 to the wiping start position.

[0083] The slider 82A is fixed to a part of the belt 86. The position of the wiper portion 82 indicated by the solid line in FIG. 10 is the retracted position PW1. The retracted position PW1 detected by the sensor SE3 is also the origin position when measuring the position of the wiper portion 82 on the movement path. When wiping the nozzle surface 20N, the recording head 20H is positioned at the standby position PH2. The standby position PH2 is a position away from the movement path of the wiper member 81, and is a position where the wiper portion 82 and the nozzle surface 20N cannot come into contact with each other. When the second slide motor 87 is driven forward while the wiper portion 82 is at the retracted position PW1, the wiper portion 82 moves in the +X direction from the retracted position PW1 and reaches the wiping start position indicated by the two-dot chain line in FIG. 10.

[0084] After the wiper unit 82 reaches the wiping start position, the recording unit 20 moves down a predetermined amount in the +B direction, and is thereby positioned at the wiping position PH5 shown in Fig. 11. This wiping position PH5 is located closer to the retracted position PH1 than the recording position PH4 and the maintenance position PH3.

[0085] 11, the wiper section 82, which is at the wiping start position located at the left end, moves in the -X direction as the second slide motor 87 is driven in the reverse direction. During this movement in the -X direction, the wiper member 81 wipes the nozzle surface 20N. The wiper section 82 can be positioned at wiping position PW2, and wipes the nozzle surface 20N at wiping position PW2.

[0086] Liquid such as ink adhering to the nozzle surface 20N can cause the flight direction of the liquid such as ink ejected from the nozzle N to bend. Furthermore, a meniscus of the liquid such as ink is formed inside the nozzle N, and if the shape of this meniscus is unstable, it can cause variations in the amount of droplets ejected from the nozzle N. The wiper unit 82 wipes the nozzle surface 20N with the wiper member 81, thereby removing liquid adhering to the nozzle surface 20N and adjusting the shape of the meniscus formed by the liquid inside the nozzle N. By performing the wiping operation of the wiper unit 82 on the nozzle surface 20N with the wiper member 81, the deflection of the flight direction of droplets ejected from the nozzle N and variations in the ejection amount are suppressed.

[0087] As shown in FIG. 2, the control unit 95 is provided in the device main body 11. The control unit 95 has a CPU 96 (Central Processing Unit 96) and a memory 97. The CPU 96 can execute various programs stored in the memory 97, and can, for example, make various decisions and issue various commands. The memory 97 stores various programs, such as a program for transporting the medium M, a program for recording information on the medium M by the recording unit 20, and a program related to a display method for displaying the status of the liquid ejection device 10 on the display unit 14A of the operation unit 14. The memory 97 also stores various counter values, such as the number of times the medium M is transported along the transport path T.

[0088] The control unit 95 controls the entire liquid ejection device 10. For example, the control unit 95 controls the recording head 20H to perform ejection control for ejecting liquid such as ink from the nozzles N of the recording head 20H. Also, for example, the control unit 95 controls the elevation drive unit 41 to perform movement control for moving the recording unit 20 along direction B via the first movement mechanism 31. Also, for example, the control unit 95 controls the first slide drive unit 75 to perform movement control for moving the cap unit 62 along direction A via the second movement mechanism 70.

[0089] Furthermore, for example, the control unit 95 controls the second slide motor 87 to perform movement control to move the wiper unit 82 along the X-axis direction via the third movement mechanism 83. Furthermore, for example, the control unit 95 controls the pump motor 79, which is the drive source of the pump 78, to control cleaning that is performed by creating a negative pressure inside the cap 64 in the capped state. Furthermore, for example, the control unit 95 controls the feed motor to rotate the pickup roller 21, thereby feeding the media M stored in the cassette 15 one sheet at a time.

[0090] Furthermore, for example, the control unit 95 controls the transport motor to drive the transport roller pairs 22, 23, 26 and the transport unit 25, thereby performing transport control to transport the medium M fed from the cassette 15 along the transport path T. Furthermore, for example, the control unit 95 controls the image reading unit 13 to read the image of the document D using the reading unit 13A. Furthermore, for example, the control unit 95 notifies the display unit 14A of the operation unit 14 to display information regarding the state of the liquid ejection device 10.

[0091] Furthermore, for example, the control unit 95 controls the components of the printing unit 12 based on detection signals output from sensors SE1, SE2, SE3, and SE4. When the recording unit 20 and cap unit 62 are no longer able to recognize their own positions, the control unit 95 performs movement control to retract the recording unit 20 along direction B away from the first maintenance unit 60, and then retract the cap unit 62 along direction A. Furthermore, for example, the control unit 95 detects that the recording unit 20 is in retracted position PH1 and that the cap unit 62 is in uncapping position PC1 based on the detection results of sensors SE1 and SE2.

[0092] Next, the regulating member 200 will be described. The liquid ejection device 10 includes the regulating member 200 that can regulate the movement of the cap portion 62 in direction A, a storage section 300 that can store the regulating member 200 when the regulating member 200 is not regulating the movement of the cap portion 62, and a fitting section 400 into which the regulating member 200 is fitted when the regulating member 200 is regulating the movement of the cap portion 62. The regulating member 200 is used to regulate the movement of the cap portion 62 when the liquid ejection device 10 is being transported, etc. The regulating member 200 is handled by a service technician.

[0093] First, the fitting portion 400 will be described. As shown in FIGS. 4, 9, and 19, the fitting portion 400 is disposed on the -X direction side of the side frame 34 adjacent to the front frame 11A. The fitting portion 400 is also located on the +B direction side of the rack 71 of the cap portion 62. As shown in FIG. 19, the fitting portion 400 has a space HK into which the regulating member 200 is fitted. When the direction in which the regulating member 200 is fitted into the space HK is defined as the fitting direction, the space HK of the regulating member 200 opens toward the -X direction, which is the front side of the fitting direction of the space HK. In this embodiment, the fitting direction is the +X direction, which is along the X-axis direction.

[0094] The fitting portion 400 has inner surfaces 403, 404, 405, and 406 that define the contour of the space HK. The inner surfaces 404, 405, and 406 are arranged along the X-axis. The inner surface 403 defines the contour of the +X direction side, which is the rear side of the fitting direction of the space HK. The inner surface 404 defines the contour of the +A direction side of the space HK along the B direction. The inner surface 405 defines the contour of the -A direction side of the space HK along the B direction. The inner surface 406 defines the contour of the +B direction side of the space HK along the A direction. The inner surface 406 faces the tooth portion 71A of the rack 71 (see FIG. 9 ). The inner surface 406 is an example of an opposing surface that faces the rack 71 of the cap portion 62. The position of the contour of the -B direction side of the space HK is determined by the rack 71 of the cap portion 62.

[0095] The restricting member 200 is fitted into the fitting portion 400 to restrict movement of the cap portion 62 at the capping position PC2 in the direction A. The restricting member 200 is fitted into the fitting portion 400 when the cap portion 62 is at the capping position PC2. As shown in FIGS. 15 to 17, 20 and 21, the restricting member 200 is box-shaped and has outer surfaces 202, 203, 204, 205, 206 and 208.

[0096] The regulating member 200 also has a regulating portion 201 on its outer surface 202. The regulating portion 201 has a sawtooth shape with multiple protrusions arranged at equal intervals in one direction. The regulating member 200 regulates movement of the cap portion 62 in direction A by the regulating portion 201 engaging with a rack 71 of the cap portion 62. The rack 71 is an example of a part of the cap portion 62. The protrusion that constitutes the regulating portion 201, when the regulating member 200 is in the fitting portion 400, on the +X side of the position where it engages with the rack 71 is inclined in a direction that moves away from the rack 71 in the +B direction as it moves in the +X direction.

[0097] The regulating member 200 may be formed of a material having lower rigidity than the material forming the rack 71 with which the regulating portion 201 engages. With this, for example, if the regulating portion 201 of the regulating member 200 and the rack 71 of the cap portion 62 are engaged and receive vibrations or impacts greater than expected, the regulating portion 201 or the regulating member 200 will deform to absorb the vibrations or impacts, thereby preventing a decrease in the performance of the rack 71 or the cap portion 62. The regulating member 200 of this embodiment is formed of PP (Polypropylene).

[0098] As shown in FIGS. 20 and 21 , when the regulating member 200 is fitted into the fitting portion 400, the outer surface 203 comes into contact with the inner surface 403 of the fitting portion 400, thereby defining the position of the regulating member 200 in the X-axis direction. Furthermore, the outer surface 204 comes into contact with the inner surface 404 of the fitting portion 400, thereby restricting movement of the regulating member 200 in the +A direction. Furthermore, the outer surface 205 comes into contact with the inner surface 405 of the fitting portion 400, thereby restricting movement of the regulating member 200 in the -A direction. Furthermore, the outer surface 206 comes into contact with the inner surface 406 of the fitting portion 400, thereby restricting movement of the regulating member 200 in the +B direction. The outer surface 206 is an example of a contact surface that faces the inner surface 406 of the fitting portion 400 when the regulating member 200 is fitted into the fitting portion 400 and is in the space HK.

[0099] When the regulating member 200 is fitted into the fitting portion 400 and is in the space HK, the protrusions of the regulating portion 201 come into contact with the multiple tooth portions 71A of the rack 71, thereby restricting movement of the cap portion 62 in the A direction. In this embodiment, the shape of the protrusions forming the regulating portion 201 and the spacing between the protrusions are set to be the same as the shape of the teeth forming the tooth portion 71A of the rack 71 and the spacing between the teeth so that the multiple protrusions of the regulating portion 201 engage with the rack 71 of the cap portion 62 when the regulating member 200 is fitted into the fitting portion 400. Note that when the regulating member 200 is fitted into the fitting portion 400 and is in the space HK, the center of the recording head 20H in the A direction is located between both ends of the regulating portion 201 in the A direction and between both ends of the inner surface 406 in the A direction.

[0100] 16 and 17, the regulating member 200 has a protrusion 212. The protrusion 212 is disposed closer to the outer surface 204 than the center of the regulating member 200. The protrusion 212 is a plate-shaped protrusion extending along the outer surfaces 202 and 206. As shown in FIG. 21, when the regulating member 200 is fitted into the fitting portion 400 and the regulating portion 201 is engaged with the rack 71, the protrusion 212 protrudes from the fitting portion 400 in the −X direction. This allows a service technician, for example, to remove the regulating member 200 from the fitting portion 400 by grasping the protrusion 212 and pulling it in the −X direction.

[0101] Furthermore, the regulating member 200 has an outer surface 207 on the side facing the inner surface 406 of the fitting portion 400 when the regulating member 200 is fitted into the fitting portion 400 and is in the space HK. The outer surface 207 is a rounded surface that continues from the outer surface 206 in the +X direction, which is the rear side of the fitting direction in the space HK, and that moves away from the inner surface 406 as it moves in the +X direction. By providing the outer surface 207, the rear side of the fitting direction of the regulating member 200 is less likely to get caught on the fitting portion 400, making it easier to fit the regulating member 200 into the fitting portion 400. The outer surface 207 is an example of a non-contact surface.

[0102] Furthermore, by providing the outer surface 207, it is possible to remove the regulating member 200 from the fitting portion 400 while rotating it around the regulating portion 201 side of the regulating member 200 as the center of rotation, as shown by the hollow arrow in FIG. 21 . When the regulating member 200 is fitted into the fitting portion 400 and is in the space HK, the range in which the outer surface 206 of the regulating member 200 contacts the inner surface 406 of the fitting portion 400 is set on the −X-direction side in the X-axis direction with respect to the range in which the regulating portion 201 of the regulating member 200 engages with the rack 71 of the cap portion 62. Therefore, for example, when a service technician pushes or pulls the protrusion 212 of the regulating member 200 in the −B direction, a moment that rotates the regulating member 200 as shown by the hollow arrow in FIG. 21 can be generated.

[0103] As shown in FIGS. 16 to 18 , the regulating member 200 has a deformation portion 210, engaged portions 209 and 213, and a gripping portion 211. For ease of explanation, the gripping portion 211 is also indicated by a two-dot chain line in FIG. 18 . The deformation portion 210 is integrally formed with the regulating member 200. The deformation portion 210 has a thin plate shape that extends toward the outer surface 205, with the fixed end located closer to the outer surface 204 than the center of the regulating member 200. Therefore, the deformation portion 210 is elastically deformable. The engaged portion 209 is provided on the tip side of the deformation portion 210, closer to the outer surface 205 than the center of the regulating member 200. The engaged portion 209 is a cylindrical protrusion that protrudes from the deformation portion 210 toward the outer surface 208, on the same side as the protrusion 212. Elastic deformation of the deformation portion 210 causes displacement of the engaged portion 209.

[0104] The gripping portion 211 is a plate-like protrusion located on the tip side of the deforming portion 210, extending from the deforming portion 210 toward the outer surface 203. For example, when the gripping portion 211 is gripped and pulled toward the outer surface 203, the deforming portion 210 elastically deforms, and the engaged portion 209 is displaced in a direction that reduces the amount by which the engaged portion 209 protrudes from the outer surface 208. The engaged portion 213 is a plate-like protrusion extending from the protruding portion 212 toward the outer surface 204. A gap is provided between the engaged portion 213 and the outer surface 208.

[0105] Next, the storage unit 300 will be described. As shown in FIGS. 12, 13, and 18, the storage unit 300 is provided on the frame 121 so as to be able to store the regulating member 200 when the regulating member 200 is not regulating the movement of the cap unit 62. The storage unit 300 is disposed in a position on the frame 121 that is covered by the transport path forming member 105 in the separated position SP. The storage unit 300 is also disposed in a position on the +X side of the center of the frame 121 in the X axis direction. This makes it easy to attach and detach the regulating member 200 to and from the storage unit 300 and the fitting portion 400, as the storage unit 300 is close to the fitting portion 400 and the storage unit 300 and the fitting portion 400 are located in positions that are accessible from the -Y side when the first door 16 is open.

[0106] 18, the storage section 300 has engaging sections 309 and 312. The engaging section 309 engages with the engaged section 209 of the regulating member 200. The engaging section 312 engages with the engaged section 213 of the regulating member 200. The engaging section 309 is a circular through-hole disposed in the frame 121. The diameter of the engaging section 309 is set to a size that allows the engaged section 209 of the regulating member 200 to be inserted therein. The engaging section 312 is a through-hole that is disposed in the frame 121 at a position away from the engaging section 309 in the −X direction. The engaging section 312 is an elongated hole that is long in the X-axis direction and into which the protrusion 212 and the engaged section 213 of the regulating member 200 can be inserted.

[0107] 18 , when the regulating member 200 is in the storage unit 300, the engaged portions 209, 213 engage with the engaging portions 309, 312 of the storage unit 300, thereby fixing the regulating member 200 to the storage unit 300. For example, when storing the regulating member 200 in the storage unit 300, the service technician opens the first door 16 and displaces the transport path forming member 105 from the separated position SP to the transport position TP. Then, the service technician moves the regulating member 200 from a position that is in the +Z direction and on the +X direction side with respect to the position of the regulating member 200 in FIG. 18 toward the frame 121, and inserts the protrusion 212 and the engaged portion 213 into the engaging portion 312.

[0108] Then, with outer surface 208 of regulating member 200 in contact with frame 121, regulating member 200 is slid in the -X direction. As a result, engaged portion 209 of regulating member 200 fits into and engages with engaging portion 309 of storage section 300. As a result, frame 121 fits into the gap between engaged portion 213 of regulating member 200 and outer surface 208, and engaged portion 213 and engaging portion 312 engage with each other.

[0109] Furthermore, when removing the regulating member 200 fixed to the storage unit 300 from the storage unit 300, the service technician opens the first door 16 and displaces the transport path forming member 105 from the separated position SP to the transport position TP. Then, from the state shown in FIG. 18 , the service technician grips the knob 211 of the regulating member 200 and pulls it in the +Z direction, thereby displacing the engaged portion 209 in the +Z direction and releasing the engagement with the engaging portion 309. Then, the service technician slides the regulating member 200 in the +X direction to release the engagement between the engaged portion 213 and the engaging portion 312. Then, by moving the regulating member 200 in the +Z direction, the regulating member 200 is removed from the storage unit 300.

[0110] When fitting the regulating member 200 into the fitting portion 400, the service technician moves the transport unit 25 and other components of the transport path T located on the -Y direction side of the fitting portion 400 to their retracted positions. The service technician then confirms that the cap portion 62 is at the capping position PC2. If the cap portion 62 is not at the capping position PC2, the service technician moves the cap portion 62 to the capping position. The service technician then fits the regulating member 200 into the fitting portion 400. This causes the regulating portion 201 of the regulating member 200 to engage with the rack 71 of the cap portion 62, and the regulating member 200 restricts the cap portion 62 from moving in the direction A at the capping position PC2. In this case, the position at which the regulating member 200 is fitted into the fitting portion 400 is the position at which the regulating portion 201 contacts the rack 71 of the cap portion 62. That is, the regulating member 200 is detachable at the position at which the regulating portion 201 contacts the rack 71 of the cap portion 62.

[0111] Next, the regulating member 500 will be described. The liquid ejection device 10 includes a regulating member 500 that can regulate movement of the recording unit 20 in direction B, and a storage section 600 that can store the regulating member 500 when the regulating member 500 is not regulating movement of the recording unit 20. The regulating member 500 is used to regulate movement of the recording unit 20 when the liquid ejection device 10 is being transported, etc. The regulating member 500 is handled by a service technician.

[0112] First, the storage unit 600 will be described. As shown in Fig. 14 and Fig. 26, the storage unit 600 is provided in a position of the storage exterior 18C that is covered by the second door 18D in the closed state so that the regulating member 500 can be stored when the regulating member 500 does not regulate the movement of the recording unit 20. As shown in Fig. 27, the storage unit 600 includes a storage space AK, engagement portions 609A and 609B, an insertion space SK, and a bottom surface 603.

[0113] The storage space AK is a space that stores the regulating member 500 and is open toward the +X direction. The engaging portions 609A and 609B engage with engaged portions 509A and 509B of the regulating member 500, which will be described later. The engaging portion 609A is a recess that opens into a side surface that defines the outline of the storage space AK on the +Z direction side of the inner surface of the storage section 600. The engaging portion 609B is a recess that opens into a side surface that defines the outline of the storage space AK on the -Z direction side of the inner surface of the storage section 600.

[0114] The insertion space SK is a space into which a regulating portion 501 of the regulating member 500, which will be described later, is inserted when the regulating member 500 regulates the movement of the recording unit 20. The insertion space SK is provided on the -X direction side of the storage space AK, and opens toward the +X direction, which is the storage space AK side. The bottom surface 603 is a surface that defines the outline of the insertion space SK on the -X direction side, and is the surface located at the innermost part of the storage unit 600.

[0115] Holes 601A and 601B are provided in the bottom surface 603. As shown in Fig. 28, the holes 601A and 601B are through-holes spaced apart in the direction B so that regulating portions 501A and 501B of the regulating member 500, which will be described later, can pass through when the regulating member 500 is inserted into the insertion space SK. Then, as shown in Fig. 29, the regulating portions 501A and 501B that have passed through the holes 601A and 601B protrude toward the guide rail 37, which is the -X direction side of the storage unit 600. Then, the regulating portions 501A and 501B protruding toward the guide rail 37 come into contact with the guide roller 29 of the recording unit 20 at the maintenance position PH3, causing the regulating member 500 to restrict movement of the recording unit 20 in the direction B.

[0116] 27, the holes 601A and 601B are provided at positions overlapping with the guide rail 37 when viewed from the direction along the X-axis. Furthermore, the holes 601A and 601B are arranged at an interval in the direction B so that the guide roller 29 of the recording unit 20 at the maintenance position PH3 is located between the holes 601A and 601B in the direction B. Therefore, the insertion space SK and the storage unit 600 including the insertion space SK are provided at positions overlapping with the guide rail 37 when viewed from the direction along the X-axis.

[0117] The regulating member 500 is inserted into the insertion space SK of the storage unit 600 to regulate movement of the recording unit 20 at the maintenance position PH3 in direction B. The regulating member 500 is inserted into the insertion space SK when the recording unit 20 is at the maintenance position PH3. As shown in FIGS. 22 to 25, the regulating member 500 has a regulating portion 501, an extending portion 502, a base portion 503, and deformation portions 510A and 510B.

[0118] The restricting portion 501 includes a pair of restricting portions 501A and 501B. The restricting portions 501A and 501B are rectangular pillar-shaped protrusions protruding from the base portion 503. The restricting portions 501A and 501B are arranged at an interval, and the base portion 503 is located between the restricting portions 501A and 501B. The extending portion 502 is a plate-shaped protrusion extending from the base portion 503 in the direction opposite to the direction in which the restricting portions 501A and 501B protrude from the base portion 503. When the restricting member 500 is stored in the storage portion 600, the outer surface of the restricting member 500 seen from the +X direction side of the storage portion 600 is formed by the extending portion 502, the base portion 503, and the restricting portion 501.

[0119] As shown in FIGS. 14 and 26 , when the regulating member 500 is stored in the storage unit 600, the outer surface of the regulating member 500 covers the opening on the +X direction side of the storage space AK of the storage unit 600. Furthermore, when the regulating member 500 is stored in the storage unit 600, the outer surface of the regulating member 500 is flush with the outer surface on the +X direction side of the storage exterior 18C. This makes it difficult for a user to remove the regulating member 500 from the storage unit 600. Furthermore, the regulating member 500 is configured so that the outer surface of the regulating member 500 is the same color as the outer surface on the +X direction side of the storage exterior 18C. This makes it difficult for a user to recognize that the regulating member 500 is a separate member from the storage exterior 18C when the regulating member 500 is stored in the storage unit 600, as it blends in with the storage exterior 18C.

[0120] 22 to 25, engaged portion 509 includes a pair of engaged portions 509A and 509B. Engaged portion 509A is a protrusion disposed on the tip side of deforming portion 510A. Engaged portion 509B is a protrusion arranged on the tip side of deforming portion 510B. Deforming portions 510A and 510B are thin plate-like protrusions protruding from the surface of regulating member 500 opposite the outer surface formed by extending portion 502. Therefore, deforming portions 510A and 510B are elastically deformable. Engaged portions 509A and 509B are displaced as a result of elastic deformation of deforming portions 510A and 510B. Engaged portion 509A and engaged portion 509B are arranged with a gap between them so that, when regulating member 500 is housed in storage portion 600, engaged portion 509A engages with engaging portion 609A of storage portion 600 and engaged portion 509B engages with engaging portion 609B of the storage portion.

[0121] 26 , when the regulating member 500 is in the storage space AK of the storage unit 600, the engaged portions 509A, 509B engage with the engaging portions 609A, 609B of the storage unit 600, thereby fixing the regulating member 500 to the storage unit 600. For example, when storing the regulating member 500 in the storage unit 600, a service technician opens the second door 18D, aligns the engaged portions 509A, 509B of the regulating member 500 with the positions of the engaging portions 609A, 609B of the storage unit 600, and inserts the engaged portions 509A, 509B into the storage space AK of the storage unit 600. As a result, the engaged portions 509A, 509B engage with the engaging portions 609A, 609B of the storage unit 600, and the regulating member 500 is fixed to the storage unit 600.

[0122] Furthermore, when removing the regulating member 500 fixed to the storage unit 600 from the storage unit 600, the service technician opens the second door 18D, inserts tweezers or the like into the gap between the regulating member 500 and the storage unit 600 from the +X direction side, and deforms the deformation portion 510A of the regulating member 500 in the +Z direction and deforms the deformation portion 510B in the -Z direction. This disengages the engaged portions 509A, 509B of the regulating member 500 from the engaging portions 609A, 609B of the storage unit 600. Then, the regulating member 500 is removed from the storage unit 600 by moving the regulating member 500 in the +X direction.

[0123] When inserting the regulating member 500 into the insertion space SK, the service technician opens the second door 18D. Then, as shown in FIG. 27 , the service technician confirms that the guide roller 29 is positioned between the holes 601A and 601B in the direction B. If the guide roller 29 is not positioned between the holes 601A and 601B, the service technician moves the recording unit 20 to the maintenance position PH3. Then, the service technician inserts the regulating member 500 into the insertion space SK with the regulating portion 501A facing the hole 601A and the regulating portion 501B facing the hole 601B. The regulating member 500 is inserted into the storage unit 600 until the base 503 of the regulating member 500 contacts the bottom surface 603 of the storage unit 600, causing the regulating portions 501A and 501B to protrude toward the guide rail 37.

[0124] This allows the regulating portions 501A and 501B to come into contact with the guide roller 29 of the recording unit 20 at the maintenance position PH3. The regulating member 500 can then regulate movement of the recording unit 20 in the B direction. Specifically, the +B side of the regulating portion 501A comes into contact with the guide roller 29, causing the regulating member 500 to regulate movement of the recording unit 20 in the -B direction, and the -B side of the regulating portion 501B comes into contact with the guide roller 29, causing the regulating member 500 to regulate movement of the recording unit 20 in the +B direction. In this case, the position where the base 503 of the regulating member 500 comes into contact with the bottom surface 603 of the storage unit 600 is the position where the regulating portion 501 comes into contact with the guide roller 29 of the recording unit 20. That is, the regulating member 500 is detachable to a position where the regulating portion 501 comes into contact with the guide roller 29 of the recording unit 20.

[0125] The regulating member 500 may be formed of a material with lower rigidity than the material constituting the guide roller 29 with which the regulating portion 501 comes into contact. With this, for example, if the regulating portion 501 of the regulating member 500 and the guide roller 29 of the recording unit 20 are subjected to vibrations or impacts greater than expected while they are in contact, the regulating portion 501 or the regulating member 500 will deform to mitigate the vibrations or impacts, thereby preventing a decrease in the performance of the guide roller 29 or the recording unit 20. The regulating member 500 of this embodiment is formed of PP (Polypropylene).

[0126] 27, a rib 615 protruding in the +B direction is arranged on the inner surface of the storage portion 600 that defines the outline of the insertion space SK on the -B direction side. 23 to 25, a groove 515 through which the rib 615 can pass when the restriction member 500 is inserted into the insertion space SK is arranged in the restriction portion 501A of the restriction portion 501 of the restriction member 500. 23 to 25, this prevents the restriction member 500 from being inserted into the insertion space SK in a state where the restriction portion 501B faces the hole 601A and the restriction portion 501A faces the hole 601B.

[0127] As described above, the liquid ejection device 10 according to the first embodiment can provide the following effects.

[0128] The liquid ejection device 10 includes a moving part MP that is movable in a movement direction MD that intersects the horizontal direction, and a regulating member 200, 500 that has a regulating part 201, 501 and is detachable at a position where the regulating part 201, 501 contacts a part of the moving part MP. The regulating member 200, 500 regulates the movement of the moving part MP in the movement direction MD by the regulating part 201, 501 contacting a part of the moving part MP. Thus, since the liquid ejection device 10 includes the regulating member 200, 500 that regulates the movement of the moving part MP, it is possible to prevent the moving part MP from shifting position due to vibration, impact, or the like. Furthermore, because the regulating part 201, 501 of the regulating member 200, 500 is not fixed to the moving part MP with a screw or the like, the movement of the moving part MP can be regulated with a simple configuration, making it easy to reduce the size of the liquid ejection device 10.

[0129] The liquid ejection device 10 includes a storage unit 300, 600 that can store the regulating member 200, 500 when the regulating member 200, 500 is not regulating the movement of the moving part MP. As a result, the regulating member 200, 500 can be stored in the storage unit 300, 600 when not in use, so the regulating member 200, 500 is less likely to be lost.

[0130] When the regulating member 200, 500 is in the storage section 300, 600, it is fixed to the storage section 300, 600. In this way, when the regulating member 200, 500 is not in use, the regulating member 200, 500 is stored in the storage section 300, 600 and fixed thereto, making it difficult to lose the regulating member 200, 500.

[0131] The storage section 300, 600 has engaging sections 309, 312, 609A, 609B, and the regulating member 200, 500 has engaged sections 209, 213, 509A, 509B that engage with the engaging sections 309, 312, 609A, 609B. With this, when the regulating member 200, 500 is not in use, the regulating member 200, 500 is stored in the storage section 300, 600 and fixed by the engagement, making it difficult to lose the regulating member 200, 500.

[0132] The restricting members 200, 500 have engaged portions 209, 509A, 509B on elastically deformable deformation portions 210, 510A, 510B. By deforming the deformation portions 210, 510A, 510B, the engaged portions 209, 509A, 509B are displaced, and the engaged portions 209, 213, 509A, 509B can be engaged with and disengaged from the engaging portions 309, 312, 609A, 609B.

[0133] The cap part 62 has a rack 71, and the movement of the cap part 62 in the direction A is restricted by the engagement of the restricting part 201 of the restricting member 200 with the rack 71. This provides a suitable configuration for restricting the movement of the cap part 62 when the liquid ejection device 10 is being transported, for example.

[0134] The liquid discharger 10 includes a fitting portion 400 into which the regulating member 200 is fitted, and when the regulating member 200 is fitted into the fitting portion 400, the regulating portion 201 engages with the rack 71, and the regulating member 200 has a protrusion 212 that protrudes from the fitting portion 400 when the regulating portion 201 is engaged with the rack 71. This makes it easy to remove the regulating member 200 from the fitting portion 400 because the protrusion 212 can be grasped.

[0135] The fitting portion 400 has an inner surface 406 that defines a space HK into which the regulating member 200 is fitted. The inner surface 406 faces the rack 71 along the direction in which the regulating member 200 is fitted into the fitting portion 400. The regulating member 200 has an outer surface 206 that contacts the inner surface 406 and an outer surface 207 that does not contact the inner surface 406 on the side that faces the inner surface 406 when the regulating member 200 is in the space HK. The outer surface 207 continues from the outer surface 206 to the back side of the space HK and is a rounded surface that moves away from the inner surface 406 as it gets further back. This makes it easy to fit the regulating member 200 into the fitting portion 400. It also makes it easy to remove the regulating member 200 from the fitting portion 400.

[0136] The liquid ejection device 10 includes a recording unit 20 capable of ejecting ink from nozzles N, and a cap unit 62 having a cap 64 that covers the nozzles N and that is movable between a capping position PC2 where the cap 64 covers the nozzles N and an uncapping position PC1 where the cap 64 is spaced from the capping position PC2, and the movable unit MP is the cap unit 62. This makes it possible to realize a suitable configuration for restricting the movement of the cap unit 62.

[0137] The liquid discharge device 10 includes a storage section 300 that can store the regulating member 200 when the regulating member 200 is not restricting the movement of the cap section 62, and a first door 16 that can take an open state that allows access to the storage section 300 and a closed state that prevents access, and the regulating member 200 is stored in the storage section 300 so as not to be visible when the first door 16 is in the open state. In this way, the regulating member 200 is stored in a position that cannot be seen when the first door 16 is in the open state, and therefore, it is possible to prevent the user from handling the regulating member 200.

[0138] The liquid ejection device 10 includes a transport path forming member 105 that forms a transport path T1 along which a medium M, on which recording is performed by ejecting ink from the recording unit 20, is transported, and the transport path forming member 105 is displaceable between a separated position SP when the first door 16 is in an open state and a transport position TP when the first door 16 is in a closed state, the separated position SP being a position where the transport path forming member 105 covers the storage unit 300, and the transport position TP being a position where the transport path forming member 105 can transport the medium M but does not cover the storage unit 300. This allows the regulating member 200 to be stored in a position that cannot be seen when the first door 16 is in an open state, without the need to provide a separate cover member that covers the storage unit 300.

[0139] The liquid ejection device 10 includes a guide rail 37 extending in the direction B, and the moving part MP has a guide roller 29 guided by the guide rail 37, and the restricting member 500 restricts the movement of the moving part MP in the direction B by bringing the restricting part 501 into contact with the guide roller 29. This provides a suitable configuration for restricting the movement of the moving part MP when the liquid ejection device 10 is being transported, for example.

[0140] The liquid ejection device 10 includes a recording unit 20 capable of ejecting ink from the nozzles N, and the moving unit MP is the recording unit 20. This makes it possible to realize a suitable configuration for restricting the movement of the recording unit 20.

[0141] The liquid ejection device 10 includes a storage unit 600 that can store the regulating member 500 when the regulating member 500 is not restricting the movement of the recording unit 20. The storage unit 600 has holes 601A and 601B in a bottom surface 603 and is provided at a position that overlaps with the guide rail 37 when viewed from the X-axis direction. The regulating member 500 restricts the movement of the recording unit 20 when the regulating member 501 contacts the guide roller 29 through the holes 601A and 601B. This allows the regulating member 500 to be easily changed from a state where it is stored in the storage unit 600 to a state where it restricts the movement of the recording unit 20. Furthermore, the holes 601A and 601B of the storage unit 600 can be hidden by the regulating member 500 stored in the storage unit 600.

[0142] The liquid discharger 10 is provided with a second door 18D that can be in an open state that allows access to the storage unit 600 and a closed state that prevents access, and the restricting member 500 in the storage unit 600 becomes visible when the second door 18D is in the open state, and becomes invisible when the second door 18D is in the closed state. In this way, the restricting member 500 is stored in a position that cannot be seen when the second door 18D is in the closed state, and therefore, the user can be prevented from handling the restricting member 500.

[0143] The liquid ejection device 10 according to the above embodiment of the present disclosure is basically configured as described above, but it is of course possible to modify or omit parts of the configuration without departing from the spirit of the present disclosure. Furthermore, the above embodiment and other embodiments described below can be combined with each other within the scope of technical compatibility. Other embodiments will be described below.

[0144] In the above embodiment, the regulating member 200, 500 may not be fixed to the storage section 300, 600 when it is in the storage section 300, 600. In this case, the engaged portions 209, 213 of the regulating member 200, the engaged portions 509A, 509B of the regulating member 500, the engaging portions 309, 312 of the storage section 300, and the engaging portions 609A, 609B of the storage section 600 may be omitted.

[0145] In the above embodiment, the storage unit 300 does not have to be arranged on the frame 121. For example, the storage unit 300 may be arranged in a position that is accessible when the first door 16 is in an open state and is hidden by the components that make up the transport path T when viewed from the -Y direction side. Also, for example, the storage unit 300 may be arranged on the first door 16. Also, for example, the storage unit 300 may be arranged in a position of the storage exterior 18C that is covered by the second door 18D in a closed state, similar to the storage unit 600.

[0146] In the above embodiment, as long as the insertion space SK is positioned so as to overlap with the guide rail 37 when viewed from the X-axis direction, the storage unit 600 does not have to be positioned so as to overlap with the insertion space SK when viewed from the X-axis direction. For example, the storage unit 600 may be positioned in a position of the storage exterior 18C that is covered by the second door 18D in the closed state and is on the -Z direction side of the insertion space SK.

[0147] In the above embodiment, the storage units 300, 600 do not have to be provided in the device main body 11. For example, the storage units 300, 600 may be provided in a storage box included in the liquid ejection device 10, and the regulating members 200, 500 may be stored in the storage box when not regulating the movement of the moving unit MP.

[0148] In the above embodiment, the restricting portion 201 of the restricting member 200 does not have to have a sawtooth shape with multiple protrusions arranged at equal intervals in one direction. For example, the multiple protrusions arranged in one direction on the restricting portion 201 do not have to be spaced at equal intervals as long as they engage with the rack 71 of the cap portion 62. Also, for example, the restricting portion 201 may have only one protrusion that engages with the rack 71 of the cap portion 62.

[0149] In the above embodiment, the outer surface 207 of the regulating member 200 does not have to be a rounded surface that continues from the outer surface 206 in the +X direction when the regulating member 200 is in the fitting portion 400 and moves away from the inner surface 406 as it moves in the +X direction. For example, the outer surface 207 may be a slope that continues from the outer surface 206 in the +X direction when the regulating member 200 is in the fitting portion 400 and moves away from the inner surface 406 as it moves in the +X direction.

[0150] In the above embodiment, the restricting member 200 does not have to restrict movement of the cap portion 62 in the direction A by engaging the restricting portion 201 with the rack 71 of the cap portion 62. For example, the restricting portion 201 may have a configuration similar to the restricting portion 501 of the restricting member 500, and the restricting member 200 may restrict movement of the cap portion 62 in the direction A by bringing the restricting portion 201 into contact with a guide roller 74 of the cap portion 62. In this case, the guide roller 74 of the cap portion 62 is an example of a part of the moving portion MP.

[0151] In the above embodiment, the regulating member 500 does not have to regulate the movement of the recording unit 20 in the direction B by the regulating portion 501 contacting the guide roller 29 of the recording unit 20. For example, the regulating portion 501 may have a configuration similar to the regulating portion 201 of the regulating member 200, and the regulating member 500 may regulate the movement of the recording unit 20 in the direction B by the regulating portion 501 engaging with the rack 28 of the recording unit 20.

[0152] In the above embodiment, the liquid ejection device 10 may include a restricting member that restricts movement of the wiper portion 82 in the X-axis direction during transportation of the liquid ejection device 10, and a storage portion that can store the restricting member when the restricting member is not restricting movement of the wiper portion 82. For example, the restricting portion of the restricting member may have a configuration similar to the restricting portion 501 of the restricting member 500, and the restricting portion may restrict movement of the wiper portion 82 in the X-axis direction by contacting the slider 82A of the wiper portion 82 that is in the retracted position PW1. In this case, the wiper portion 82 is an example of a moving portion MP, and the slider 82A of the wiper portion 82 is an example of a part of the moving portion MP.

[0153] In the above embodiment, when the liquid ejection device 10 is first started, the control unit 95 may control the first movement mechanism 31 and the second movement mechanism 70 to move the recording unit 20 to the retracted position PH1 and the cap unit 62 to the uncapping position PC1. If the sensor SE1 does not detect the recording unit 20, the control unit 95 may cause the display unit 14A of the operation unit 14 to display a message indicating that the regulating member 500 may be inserted into the insertion space SK. If the sensor SE2 does not detect the cap unit 62, the control unit 95 may cause the display unit 14A of the operation unit 14 to display a message indicating that the regulating member 200 may be fitted into the fitting portion 400.
