In each figure, the same members are given the same reference numerals, and duplicate explanations will be omitted. In addition, in this specification, "same", "identical", and "simultaneously" do not only mean completely the same, but also mean that they are the same taking into account measurement errors, taking into account manufacturing variations in the parts. This shall include cases where they are the same, and cases where they are the same to the extent that their functionality is not impaired. Therefore, for example, "the dimensions of both are the same" means that the dimensional difference between the two is within ±10% of one dimension, more preferably within ±5%, taking into account measurement errors and manufacturing variations of parts. Particularly preferably, it is within ±3%.

In each figure, it is assumed that the liquid ejection device 10 is placed on a horizontal installation surface. Of the Z-axes perpendicular to the installation surface of the liquid ejection device 10, the side of the liquid ejection device 10 with respect to the installation surface is the +Z direction side, the opposite side is the −Z direction side, and the two axes orthogonal to the Z axis are Let the axis be the Y axis. Further, directions parallel to each of the X-axis, Y-axis, and Z-axis are referred to as the X-axis direction, the Y-axis direction, and the Z-axis direction. The X-axis direction includes both the +X direction and the -X direction. The Y-axis direction includes both the +Y direction and the -Y direction. The Z-axis direction includes both the +Z direction and the -Z direction.

The user can give instructions to the liquid ejection device 10 by performing a touch operation on the display section 14A. Note that the operation unit 14 may have a configuration including operation buttons.

The liquid ejection device 10 includes a cassette 15 that can accommodate a plurality of media M. The cassette 15 is provided in one or more stages, for example, four stages. The cassette 15 is detachably inserted into the lower part of the apparatus main body 11 by sliding in the X-axis direction. The plurality of cassettes 15 accommodate, for example, media M of different sizes or types. The cassette 15 has a handle 15A on which the user can hook his or her fingers when pulling out the cassette.

The liquid ejection device 10 includes a front frame 11A as a base frame at an end in the +X direction of the base frame, and a rear frame 11B at an end in the -X direction of the base frame. The front frame 11A and the rear frame 11B are made of metal material. A base body of the liquid ejecting device 10 is configured by fixing a motion unit 30, which will be described later, to the front frame 11A and the rear frame 11B. The housing of the liquid ejecting device 10 is formed by attaching the exterior member to the base of the liquid ejecting device 10 .

The liquid ejection device 10 includes a first door 16 and a plurality of cover doors 17 on the side surface of the device main body 11 on the −Y direction side. The first door 16 and the cover door 17 constitute a part of the exterior member. The first door 16 and the cover door 17 can be opened and closed between an open state in which the transport path T (see FIG. 2) is exposed and a closed state in which the transport path T is covered. The first door 16 and the cover door 17 have handles 16A and 17A for the user to open and close. The first door 16 includes a feeding tray 16T on which the medium M can be placed. The feeding tray 16T is attached to the first door 16 so as to be openable and closable. The feeding tray 16T has a handle 16B for the user to open and close.

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

The liquid ejection device 10 includes a second door 18D on the side surface of the device main body 11 on the +X direction side. The second door 18D constitutes a part of the exterior member. The second door 18D has an open state (see FIG. 14) in which the liquid storage section 98, a waste liquid storage section 99 (described later), a storage section 600 (described later), or a regulating member 500 stored in the storage section 600 can be accessed (see FIG. 14), and a liquid storage section 99 (see FIG. 14). 98, the waste liquid storage section 99, the storage section 600, or a closed state that covers the regulating member 500 stored in the storage section 600 (see FIG. 1). The closed state of the second door 18D can also be said to be a state in which 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 cannot be accessed.

The liquid ejection device 10 includes a discharge section 19 between the device main body 11 and the image reading section 13. The ejection section 19 includes an ejection tray 19A forming the bottom thereof. The ejection tray 19A is a member formed in a plate shape, and has a placement surface 19B on which the ejected medium M is placed. The ejection tray 19A is inclined at a predetermined angle such that the downstream side in the ejection direction in which the recorded medium M is ejected is higher than the upstream side. Further, the ejection tray 19A is arranged at a position in the +Z direction of the recording section 20 in the Z direction.

As shown in FIG. 2, the liquid ejecting device 10 includes a transport path T along which a medium M to be recorded by the recording unit 20 is transported. Note that in FIG. 2, each component of the liquid ejection device 10 is shown in a simplified manner. The medium M is conveyed through a conveyance path T shown by a broken line in FIG. The AB coordinate system shown on the YZ plane is an orthogonal coordinate system. The A direction is a direction intersecting the X-axis direction. The direction A is the direction in which the medium M is transported in the region of the transport path T that faces the recording head 20H of the recording section 20. The upstream direction of the A direction is called the -A direction, and the downstream direction is called the +A direction.

In this embodiment, the A direction is a direction inclined such that the +A direction is located in the +Z direction more 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 manner, at the recording position PH4 where recording is performed by the recording unit 20, the transport direction of the medium M is an inclined direction that intersects both the horizontal direction and the Z-axis direction.

In the conveyance path T, a conveyance path T1 extending from an external device and a conveyance path T2 extending from a feed tray 16T provided in the apparatus main body 11 merge. As shown in FIGS. 2, 12, and 13, the liquid ejecting device 10 includes a conveyance path forming member 105 at a position where the conveyance path T1 and the conveyance path T2 join. As shown in FIGS. 12 and 13, the conveyance path forming member 105 is arranged on the +Z direction side of the frame 121 extending in the X-axis direction. The frame 121 is a plate-shaped metal member that is disposed on the device main body 11 and connects the front frame 11A and the rear frame 11B.

Note that a storage section 300 that stores a regulating member 200, which will be described later, is arranged in the frame 121. From this, it can be said that the first door 16 can take an open state that allows access to the storage section 300 and a closed state that makes the storage section 300 inaccessible.

The conveyance path forming member 105 is arranged in the apparatus main body 11 so as to be rotatable about a rotation axis (not shown) along the X-axis direction. The conveyance path forming member 105 is movable between a conveyance position TP when the first door 16 is in a closed state and a remote position SP when the first door 16 is in an open state.

As shown in FIG. 2, the transport position TP is a position where the transport path forming member 105 is along the transport path T and is a position where the medium M can be transported. 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.

The remote position SP is a position away from the transport position TP in the −Z direction. As shown in FIG. 12, the conveyance path forming member 105 located at the remote position SP covers the storage section 300 or the regulating member 200 stored in the storage section 300. Therefore, when the first door 16 is opened, the conveyance path forming member 105 is located at the remote position SP. Therefore, the regulating member 200 stored in the storage section 300 cannot be visually recognized when the first door 16 is in the open state. For example, when a service person accesses the storage section 300 or the regulating member 200 stored in the storage section 300, the first door 16 is opened and the conveyance path forming member 105 is moved to a remote position as shown in FIG. The storage unit 300 and the regulating member 200 are moved from SP to a position where they are not covered, for example, a transport position TP.

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

The transport path T forms a curved portion in a region facing the sensor SE4, and extends in the direction A in a region downstream from this curved portion. Downstream of the transport unit 25 in the transport path T, a transport path T3 and a transport path T4 heading toward the discharge section 19, and a reversing path T5 for reversing the medium M from front to back are provided. The discharge section 19 is provided with a discharge tray (not shown) in line with the transport path T4. Note that, when double-sided recording is performed, the reversing path T5 is a path into which the medium M that has finished recording on the first side is carried in before recording on the second side is performed. At this reversing path T5, the medium M is reversed, and as in the case of recording on the first side, it is again sent through the transport path T to the recording position, thereby performing recording on the second side.

The transport unit 25 supports the medium M being transported. The transport unit 25 includes 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. As a method for attracting the medium M to the conveyor belt 25B, an air suction method, an electrostatic adsorption method, or the like can be adopted. In this way, the conveyor belt 25B supports the medium M while adsorbing it. The transport unit 25 is arranged to face the recording section 20 in the B direction.

The recording unit 20 moves in the B direction, which is the direction facing the transport unit 25. The recording unit 20 of this embodiment reciprocates in direction B, which is inclined by 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 B direction. The B direction is an example of the moving direction MD in which the recording section 20 moves. The B direction is the direction in which the recording section 20 moves forward and backward relative to the transport unit 25. The direction in which the recording head 20H approaches the transport path T in the B direction is referred to as the +B direction, and the direction away from the transport path T is referred to as the -B direction. The -B direction is a direction in which the recording head 20H moves diagonally upward along the direction away from the transport unit 25.

The B direction is a direction in which the recording unit 20 is displaced, and is a direction that includes a component in the Z direction, which is the height direction. In this embodiment, the B direction is a direction that is inclined so that the -B direction is located in the +Z direction rather than the +B direction, and is orthogonal to the A direction. Further, the B direction is a direction intersecting the X-axis direction.

The recording unit 20 is configured to be movable between a retreat position PH1 indicated by a chain double-dashed line in FIG. 2 and a recording position PH4 indicated by a solid line in FIG. By moving in the B direction, the recording unit 20 can move to a plurality of positions including at least the retreat position PH1 and the recording position PH4. The moving direction of the recording section 20 is also referred to as the ascending/descending direction because the movement causes the recording section 20 to be displaced in the Z-axis direction, and is accompanied by upward and downward movements. Note that the moving direction of the recording unit 20 is not limited to a direction that makes a predetermined angle with respect to the horizontal, but may be the horizontal direction or the Z-axis direction.

The recording unit 20 of this embodiment ascends in the −B direction and descends 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 nozzle N (see FIG. 9) of the recording head 20H opens, is the vertical direction of the recording head 20H.

In the recording section 20, the recording head 20H discharges a liquid such as ink onto the portion of the medium M supported by the transport unit 25 while the recording head 20H is at the recording position PH4. Thereby, the recording unit 20 records information such as images on the medium M. The liquid ejecting device 10 includes a sensor SE1 that can detect the recording section 20 at the retracted position PH1. The sensor SE1 is configured to be able to detect the recording unit 20 when it is in the retracted position PH1. The retreat position PH1 detected by the sensor SE1 is also the origin position when measuring the position of the recording unit 20 on the movement route.

The recording unit 20 includes a recording head 20H that discharges ink, which is an example of liquid. The recording head 20H is arranged to face the transport unit 25 in the B direction at the 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 such that a recording head 20H that discharges ink covers the entire area in the X-axis direction, which is the width direction of the medium M.

Further, the recording unit 20 performs recording using a line recording method that allows recording over the entire width of the medium M without moving 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 an example of the width direction of the recording section 20. However, the recording unit 20 is not limited to this, and may be of a serial recording type in which it is mounted on a carriage and discharges ink while moving in the X-axis direction. That is, as long as the liquid ejecting apparatus 10 includes the first maintenance section 60, the recording method of the recording section 20 may be used in either manner.

The liquid ejecting device 10 includes a first maintenance section 60 in the device main body 11 that performs maintenance on the nozzle surface 20N of the recording section 20. As shown in FIGS. 5 to 8, the first maintenance section 60 moves to a capping position PC2 (see FIG. 8) and a non-capping position PC1 (see FIG. 5), which is evacuated from the capping position PC2 in the -A direction. It is possible. The recording unit 20 is movable from the recording position PH4 to a maintenance position PH3 (see FIG. 8) which is a predetermined distance away from the recording position PH4 in the -B direction. The first maintenance section 60 performs maintenance on the recording head 20H located at the maintenance position PH3.

The first maintenance section 60 is configured to be movable to a non-capping position PC1 and a capping position PC2 by moving in the A direction. The first maintenance unit 60 of this embodiment reciprocates in the direction A that is inclined at a predetermined angle with respect to the horizontal plane. The first maintenance section 60 is an example of a moving section MP that is movable in the A direction. The A direction is an example of the moving direction MD in which the first maintenance section 60 moves. The first maintenance section 60 is a cap section 62 that will be described later.

The first maintenance section 60 moves in the +A direction from the non-capping position PC1 and performs maintenance on the recording head 20H at the capping position PC2. When the liquid ejecting device 10 is in a recording operation, the first maintenance section 60 stands by at the non-capping position PC1.

The liquid ejection device 10 includes a sensor SE2 that can detect the first maintenance section 60 in the non-capping position PC1. The sensor SE2 is configured to be able to detect the first maintenance section 60 when it is in the non-capping position PC1. The first maintenance section 60 is detected by the sensor SE2 by retreating from the capping position PC2 in the -A direction. The non-capping position PC1 detected by the sensor SE2 is also the origin position when measuring the position of the first maintenance section 60 on the movement route. Note that details of the maintenance performed by the first maintenance section 60 will be described later.

Further, as shown in FIG. 2, the liquid ejection device 10 includes a control section 95 that controls the operation of each part of the liquid ejection device 10, and a liquid storage section 98 that stores liquid such as ink, in the device main body 11. , and a waste liquid storage section 99 that stores ink and the like as waste liquid. The liquid storage section 98 supplies ink to the recording head 20H via a tube (not shown).

Next, the configuration of the motion unit 30 will be explained. As shown in FIG. 3, the liquid ejection device 10 includes a motion unit 30 within the device main body 11. The motion unit 30 includes a first moving mechanism 31 (see FIGS. 5 to 8) that moves the recording section 20, a second moving mechanism 70 (see FIGS. 4 to 8) that moves the first maintenance section 60, and a first moving mechanism 31 (see FIGS. 5 to 8) that moves the recording section 20. This unit is integrally assembled with a third moving mechanism 83 (see FIGS. 10 and 11) that moves the second maintenance section 80.

The first moving mechanism 31 moves the recording unit 20 in the B direction intersecting the nozzle surface 20N (see FIG. 4). The nozzle surface 20N is a surface facing the conveyance path T in the recording head 20H. The second moving mechanism 70 moves the first maintenance section 60 in the direction A along the nozzle surface 20N. The control unit 95 controls the operations of the first moving mechanism 31 and the second moving mechanism 70. The motion unit 30 supports the recording section 20 movably in the B direction, supports the first maintenance section 60 so as to be movable in the A direction, and further supports the second maintenance section 80 so as to be movable in the X-axis direction.

That is, the first maintenance section 60 is movable in the A direction and performs the first maintenance on the recording head 20H. The second maintenance section 80 is movable in the X-axis direction, and performs second maintenance on the recording head 20H, which is different from the first maintenance. Note that the moving direction of the second maintenance section 80 in this embodiment is the X-axis direction, but as long as the second maintenance can be performed without interfering with the first maintenance section 60, it may be moved in a direction other than the X-axis direction. It may be a direction.

The motion unit 30 has a main body frame 33 that constitutes a main body portion. The main body frame 33 includes 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.

As shown in FIG. 3, each of the pair of side frames 34 is configured as a side plate along the AB plane. One side frame 34 is arranged on the +X direction side, and the other side frame 34 is arranged on the −X direction side. For example, the other side frame 34 is formed with a through hole 34A through which the second maintenance section 80 moves.

One guide member 36 for movably guiding the recording section 20 in the B direction is assembled on two opposing inner surfaces of each of the pair of side frames 34. The two guide members 36 are arranged approximately symmetrically with respect to the center of the main body frame 33 in the X direction.

As shown in FIGS. 3 and 5, the guide member 36 includes a guide rail 37 extending in the B direction, and guide rails 38 and 39 branching from a midway portion of the guide rail 37 and extending in the Z direction. The guide rails 37, 38, and 39 are all groove-type rails that open toward the center of the main body frame 33 in the inserted within. The guide rail 37 is an example of a guide section that guides the recording section 20 in the B direction.

The recording unit 20 is guided by the guide rail 37 and moves 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 be moved to a plurality of stop positions, such as a retreat position PH1, a recording position PH4, a standby position PH2, and a maintenance position PH3.

When the recording unit 20 is in the retracted position PH1, it can be guided to the guide rails 38 and 39 for replacement. In the liquid ejection apparatus 10, a user or an operator such as a service person can remove the recording unit 20 from the apparatus main body 11 for maintenance or replace it with a new one. When the user operates the operation unit 14 (see FIG. 1) to notify the liquid ejection device 10 of replacing the recording unit 20, the control unit 95 moves the recording unit 20 to the evacuation position PH1, which is also the replacement position. move it to This allows the operator to replace the recording unit 20 through the input port that is exposed when the output tray 19A is removed.

The first maintenance section 60 performs cleaning of the recording head 20H as first maintenance. As shown in FIGS. 4, 8, and 9, the first maintenance section 60 of this embodiment is a cap section 62 that cleans the recording head 20H. The cap portion 62 has a cap 64 that can cover the nozzle N of the recording head 20H. As shown in FIGS. 8 and 9, when the cap 64 is in contact with the recording head 20H and covers the nozzle N, the cap portion 62 removes thickened ink, ink containing air bubbles, etc. in the nozzle N. Force the waste liquid out. As a result, the nozzle N is cleaned by the cap portion 62. This cleaning prevents or eliminates clogging of the nozzle N.

The second maintenance section 80 maintains the recording head 20H. As shown in FIGS. 10 and 11, the second maintenance section 80 of this embodiment is a wiper section 82 that performs wiping to wipe the nozzle surface 20N of the recording head 20H as second maintenance. The wiper section 82 includes a wiper member 81, and the wiper member 81 wipes the nozzle surface 20N of the recording head 20H.

As shown in FIG. 4, the recording head 20H includes a plurality of unit heads 20U arranged in the X-axis direction. The cap portion 62 includes a plurality of caps 64 arranged in line 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.

It is configured to include a lifting drive section 41.

The length of the rack 28 is set longer than the length of one circumference of the pinion 43. By driving the elevating drive unit 41, the recording unit 20 moves in the B direction via the first moving mechanism 31. The recording unit 20 moves in the B direction while being guided by a guide rail 37 extending in the B direction. The first moving mechanism 31 moves the recording section 20 up and down along the B direction.

The elevating drive unit 41 includes, for example, a worm gear mechanism including a worm wheel attached to a rotating shaft to which a pinion 43 is attached and a worm gear that rotates the worm wheel, and a drive motor having a worm gear attached to an output shaft. The lift drive unit 41 of this embodiment is arranged at a position on the -X direction side of the rear frame 11B and on the +X direction side of an exterior member (not shown) arranged on the -X direction side of the rear frame 11B. Ru.

A plurality of guide rollers 29 made of rollers are rotatably arranged on the side surface of the recording section 20. The guide roller 29 is made of metal, for example. The plurality of guide rollers 29 are guided by the guide rail 37, so that the recording section 20 moves in the B direction along the guide rail 37. The guide roller 29 is an example of a guided portion guided by the guide rail 37.

The cap portion 62 is provided so as to be movable in the direction A, which is the moving direction MD of the cap portion 62. The cap portion 62 is guided by a guide rail 73 extending in the A direction and reciprocates in the A direction.

The liquid ejection device 10 includes a second moving mechanism 70 that moves the cap portion 62 in the direction A along the nozzle surface 20N. The second moving mechanism 70 is a rack and pinion system. As shown in FIGS. 4 to 9 and 19, the second moving mechanism 70 includes rack and pinion mechanisms 70A and 70B (see FIGS. 4 and 9) that include a rack 71 included in the cap portion 62 and a pinion 72 that is a driving gear. ) and a first slide drive section 75 that is a drive source for the pinion 72. The first slide drive unit 75 of the present embodiment is arranged at a position on the +X direction side of the front frame 11A and on the -X direction side of an exterior member (not shown) arranged on the +X direction side of the front frame 11A. be done. Therefore, in FIGS. 5 to 8, the first slide drive section 75 is indicated by a two-dot chain line.

The rack 71 may be made of metal or a resin material. As the resin material forming the rack 71, POM (polyoxymethylene), PBT (poly butylene terephthalate), etc. can be adopted. The length of the rack 71 is set 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 drive unit 75 includes, for example, a worm gear mechanism including a worm wheel attached to a rotating shaft 76 (see FIG. 4) to which a pinion 72 is attached and a worm gear that rotates the worm wheel, and a drive unit in which a worm gear is attached to an output shaft. Consists of a motor.

The cap portion 62 can be moved back and forth in the A direction by the second moving mechanism 70. The cap portion 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 portion 62 faces the recording head 20H. The non-capping position PC1 is a position where the cap section 62 is on standby when the recording section 20 is recording. The capping position PC2 is the position of the cap portion 62 when capping is performed to cover the nozzle N opening on the nozzle surface 20N of the recording head 20H.

When capping is performed, as shown in FIG. 7, in order to secure the moving path of the cap part 62 when the cap part 62 moves from the non-capping position PC1 to the capping position PC2, the recording part 20: It moves to a standby position PH2 which is evacuated by a predetermined distance in the -B direction from the recording position PH4.

As shown in FIG. 6, when the recording section 20 is at the standby position PH2, the cap section 62 moves in the +A direction from the non-capping position PC1 shown in FIGS. 5 and 6 to the capping position PC2 shown in FIG. do. 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 located at the capping position PC2 come into contact with a predetermined pressure. The position where the recording head 20H contacts the cap 64 is a maintenance position PH3 shown in FIG. The cap 64 located at the capping position PC2 covers the nozzle N (see FIG. 9) of the recording head 20H located at the maintenance position PH3.

As shown in FIGS. 8 and 9, when the cap section 62 is at the capping position PC2, the cap section 62 is away from the conveyance path T along which the medium M to be recorded by the recording section 20 is conveyed.

As shown in FIG. 9, the cap section 62 performs maintenance of the recording head 20H in a capping state in which the cap 64 covers the nozzles N of the recording head 20H. The cap portion 62 creates a negative pressure inside the cap 64 in the capped state by driving a pump motor 79 that is a drive source of a pump 78 connected to the cap 64 through a pipe 77 . The cap portion 62 forcibly discharges liquid such as ink from the nozzles N of the recording head 20H into the cap 64.

The cap portion 62 is used to empty liquid that has been forcibly discharged from the recording head 20H and for maintenance purposes from the recording head 20H at the standby position PH2 to the cap 64 at the capping position PC2 (see FIG. 7). Liquid such as ink is stored as waste liquid from the cap 64 in a waste liquid storage section 99 shown in FIG. 2 .

Next, the detailed configuration of the cap portion 62 will be explained. FIG. 9 shows the recording section 20 and the cap section 62 in a capped state. The cap part 62 is an example of a cap 64 capable of contacting the nozzle surface 20N, a cap holder 66 for holding the cap 64, and a biasing part provided between the cap 64 and the cap holder 66. A spring 65 is provided. The spring 65 biases the cap 64 toward the nozzle surface 20N. The spring 65 biases the cap 64 in the -B direction. Cap 64 is supported by spring 65.

In this embodiment, the recording head 20H includes a plurality of unit heads 20U shown in FIG. 9 arranged in the X-axis direction. The cap portion 62 includes a plurality of caps 64 arranged in a line along the X-axis direction, which is the width direction of the medium M, at a position 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 sealing 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 urging force of the spring 65 in the −B direction and the restoring force of the elastically compressed seal portion.

The cap 64 has a shape and size that can cover all the nozzles N of the nozzle surface 20N of the unit head 20U. Further, when the cap portion 62 is at the capping position PC2, the cap 64 is arranged at a position facing the nozzle surface 20N of each unit head 20U in the B direction. The cap 64 covers the plurality of nozzles N opening on the nozzle surface 20N by contacting the nozzle surface 20N of the recording head 20H with a predetermined pressure.

By covering the nozzle surface 20N with the cap 64, increase in viscosity due to drying of liquid such as ink in the nozzle N of the recording head 20H is suppressed. Note that by moving the recording unit 20 from the retracted position PH1 (see FIG. 2) in the descending direction B direction to a predetermined maintenance position PH3, the recording head 20H and the cap 64 come into contact with a predetermined pressure, and the capping state is established. It is said that

The cap 64 is attached to the cap holder 66 via a slide portion 67 so as to be movable relative to the cap holder 66 in the B direction. Due to the elastic force of the spring 65 interposed between the bottom surface of the cap 64 and the top surface of the cap holder 66, the cap 64 is biased toward the −B direction, which is the upward direction with respect 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 toward the −B direction.

The second moving mechanism 70 includes a pair of rack and pinion mechanisms 70A and 70B. A pair of racks 71 constituting rack and pinion mechanisms 70A and 70B are fixed to both side surfaces of the cap holder 66 in the X-axis direction. On the +B direction side facing the tooth portions 71A of the pair of racks 71, pinions 72, which are a pair of drive gears forming the rack and pinion mechanisms 70A and 70B, are rotatably arranged. The tooth portion 71A of the rack 71 and the tooth portion 72A of the pinion 72 mesh with each other. A pair of pinions 72 are attached to both ends of the rotating shaft 76 from the center. Furthermore, guide rollers 74 made of a plurality of rollers rotatable with the X-axis direction as the axial direction are provided on both side walls of the cap portion 62 in the X-axis direction. The guide roller 74 is made of metal, for example. The guide roller 74 is guided along the A direction (see FIGS. 8, 19, etc.) in which the guide rail 73 having a C-shaped cross section extends.

When the rotary shaft 76 is rotated by the power of the first slide drive section 75 (see FIGS. 4, 9, 19, etc.) which is the drive source of the cap section 62, the pair of pinions 72 are rotated. When the first slide drive section 75 is driven to rotate normally, the cap section 62 moves in the +A direction through the engagement between the pinion 72 and the rack 71. On the other hand, when the first slide drive section 75 is driven in the reverse direction, the cap section 62 moves in the -A direction through the engagement between the pinion 72 and the rack 71.

Next, the configuration of the wiper section 82 will be explained. As shown in FIG. 10, the wiper section 82 is movable in the X-axis direction perpendicular to the B direction and the A direction, and performs maintenance of the recording head 20H of the recording section 20. The wiper section 82 includes a wiper member 81 and a slider 82A that supports the wiper member 81.

The liquid ejecting device 10 includes a sensor SE3 that can detect the wiper section 82 in the retracted position PW1, and a third moving mechanism 83 that reciprocates the wiper section 82 in the X-axis direction. The sensor SE3 is configured to be able to detect the wiper section 82 when it is in the retracted position PW1. The third moving mechanism 83 includes a guide rail 84 that guides the slider 82A, an endless belt 86 wrapped around a pair of pulleys 85, and a second slide motor 87 that is a drive source that rotates one of the pulleys 85. , is provided.

The guide rail 84 guides the slider 82A movably along the X-axis direction. The pair of pulleys 85 are placed a predetermined distance apart in the X-axis direction. By being wound around the pair of pulleys 85, the belt 86 is arranged parallel to the nozzle surface 20N over a wider range than the movement range of the wiper member 81. The control unit 95 can also control the third moving mechanism 83. Specifically, the control unit 95 drives the second slide motor 87 in forward and reverse directions to reciprocate the wiper member 81 along a path from the retracted position PW1 to the wiping start position.

The slider 82A is fixed to a part of the belt 86. The position of the wiper portion 82 indicated by a 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 section 82 on the movement path. When wiping the nozzle surface 20N is performed, the recording head 20H is placed at the standby position PH2. The standby position PH2 is a position away from the moving path of the wiper member 81, and a position where the wiper portion 82 and the nozzle surface 20N cannot come into contact. When the second slide motor 87 is driven to rotate normally with the wiper section 82 at the retracted position PW1, the wiper section 82 moves in the +X direction from the retracted position PW1 and starts wiping as indicated by the two-dot chain line in FIG. reach the position.

After the wiper section 82 reaches the wiping start position, the recording section 20 is lowered by a predetermined amount in the +B direction, thereby being placed at the wiping position PH5 shown in FIG. 11. This wiping position PH5 is located closer to the retreat position PH1 than the recording position PH4 and the maintenance position PH3.

The wiper section 82 at the wiping start position located at the left end in FIG. 11 is moved in the -X direction by the second slide motor 87 being driven in reverse. In the process of moving in the −X direction, the wiper member 81 wipes the nozzle surface 20N. Note that the wiper portion 82 can be positioned at the wiping position PW2, and wipes the nozzle surface 20N at the wiping position PW2.

The liquid such as ink adhering to the nozzle surface 20N causes the flying direction of the liquid such as ink ejected from the nozzle N to be bent. Furthermore, a meniscus of liquid such as ink is formed within the nozzle N, but if the shape of this meniscus is unstable, it causes variations in the amount of droplets ejected from the nozzle N. By wiping the nozzle surface 20N with the wiper member 81, the wiper section 82 removes the liquid adhering to the nozzle surface 20N and adjusts the shape of the meniscus formed by the liquid inside the nozzle N. When the wiper unit 82 performs a wiping operation of the nozzle surface 20N with the wiper member 81, bending in the flight direction of droplets discharged from the nozzle N and variation in the discharge amount are suppressed.

As shown in FIG. 2, the control section 95 is provided in the device main body 11. The control unit 95 includes 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, perform various judgments and various commands. The memory 97 includes, for example, a program for transporting the medium M, a program for recording information on the medium M by the recording section 20, and a display method for displaying the status of the liquid ejecting device 10 on the display section 14A of the operation section 14. Various programs such as programs related to the above are stored. The memory 97 also stores various counter values such as the number of times the medium M is transported along the transport path T.

The control unit 95 controls the entire liquid ejection device 10 . For example, the control unit 95 performs ejection control to eject liquid such as ink from the nozzles N of the print head 20H by controlling the print head 20H. Further, for example, the control unit 95 performs movement control to move the recording unit 20 along the B direction via the first movement mechanism 31 by controlling the elevation drive unit 41 . Further, for example, the control section 95 controls the first slide drive section 75 to perform movement control to move the cap section 62 along the A direction via the second movement mechanism 70.

Further, for example, the control unit 95 performs movement control to move the wiper unit 82 along the X-axis direction via the third movement mechanism 83 by controlling the second slide motor 87 . For example, the control unit 95 controls the pump motor 79 that is the drive source of the pump 78 to control cleaning performed by creating a negative pressure inside the cap 64 in the capped state. Further, for example, the control unit 95 controls the feeding motor to rotate the pickup roller 21 to feed the media M accommodated in the cassette 15 one by one.

Further, 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 moving the medium M fed from the cassette 15 along the transport path T. Performs transport control. Further, for example, the control unit 95 controls the image reading unit 13 so that the image of the document D is read by the reading unit 13A. Further, for example, the control unit 95 performs notification to display information regarding the state of the liquid ejection device 10 on the display unit 14A of the operation unit 14.

Further, for example, the control unit 95 controls the components of the printing unit 12 based on detection signals output from the sensors SE1, SE2, SE3, and SE4. When the recording section 20 and the cap section 62 are unable to recognize their own positions, the control section 95 retracts the recording section 20 away from the first maintenance section 60 side along the B direction, and then moves the recording section 20 away from the first maintenance section 60 side. Movement control is performed to retreat along the A direction. Further, for example, the control unit 95 detects that the recording unit 20 is at the retracted position PH1 and that the cap unit 62 is at the non-capping position PC1, based on the detection results of the sensors SE1 and SE2.

Next, the regulating member 200 will be explained. The liquid ejection device 10 includes a regulating member 200 that can regulate the movement of the cap portion 62 in the direction A, and a storage portion 300 that can accommodate the regulating member 200 when the regulating member 200 does not regulate the movement of the cap portion 62. A fitting part 400 into which the regulating member 200 is fitted when the regulating member 200 regulates movement of the cap part 62 is provided. The regulating member 200 is used to regulate the movement of the cap portion 62 when the liquid ejecting device 10 is transported. The regulating member 200 is handled by a service person.

First, the fitting portion 400 will be explained. As shown in FIGS. 4, 9, and 19, the fitting portion 400 is arranged on the −X direction side of the side frame 34 adjacent to the front frame 11A. Further, the fitting portion 400 is located on the +B direction side of the rack 71 of the cap portion 62. As shown in FIG. 19, the fitting part 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 side, which is the near side in the fitting direction of the space HK. In this embodiment, the fitting direction is the +X direction, which is along the X-axis direction.

The fitting part 400 has inner surfaces 403, 404, 405, 406 that define the contour of the space HK. Inner surfaces 404, 405, and 406 are provided along the X axis. The inner surface 403 defines a contour on the +X direction side, which is the inner side in the fitting direction of the space HK. The inner surface 404 defines the contour of the space HK on the +A direction side along the B direction. The inner surface 405 defines the outline of the space HK on the −A direction side along the B direction. The inner surface 406 defines the contour of the space HK on the +B direction side along the A direction. Further, the inner surface 406 faces the tooth portion 71A of the rack 71 (see FIG. 9). The inner surface 406 is an example of the opposing surface of the cap portion 62 that faces the rack 71. Note that the position of the contour of the space HK on the −B direction side is defined by the rack 71 of the cap portion 62.

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

Further, the regulating member 200 has a regulating portion 201 on the outer surface 202. The regulating portion 201 has a sawtooth shape in which a plurality of protrusions are arranged at equal intervals in one direction. The regulating member 200 regulates movement of the cap portion 62 in the A direction by the regulating portion 201 engaging with the rack 71 of the cap portion 62 . The rack 71 is an example of a portion of the cap portion 62. In the protrusions constituting the regulating part 201, when the regulating member 200 is in the fitting part 400, the side that is in the +X direction from the position where it engages with the rack 71 is further away from the rack 71 in the +B direction as it goes in the +X direction. It is sloping.

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. According to this, for example, when the regulating part 201 of the regulating member 200 and the rack 71 of the cap part 62 are engaged with each other, if a vibration or impact larger than expected is received, the regulating part 201 or the regulating member 200 By deforming, vibrations and shocks can be alleviated, and the performance of the rack 71 or the cap portion 62 can be prevented from deteriorating. Note that the regulating member 200 of this embodiment is formed of PP (Polypropylene).

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

When the regulating member 200 is fitted into the fitting part 400 and is in the space HK, the protrusion of the regulating part 201 comes into contact with the plurality of teeth 71A of the rack 71, thereby regulating the movement of the cap part 62 in the A direction. The shape of the protrusions forming the regulating part 201 of this embodiment and the spacing between the protrusions are such that when the regulating member 200 is fitted into the fitting part 400, the plurality of protrusions of the regulating part 201 engage with the rack 71 of the cap part 62. The shape of the teeth forming the tooth portion 71A of the rack 71 and the spacing between the teeth are set to be the same. Note that when the regulating member 200 is fitted into the fitting part 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 part 201 in the A direction, and It is located between both ends in the A direction.

As shown in FIGS. 16 and 17, the regulating member 200 has a protrusion 212. As shown in FIG. The protrusion 212 is arranged closer to the outer surface 204 than the center of the regulating member 200 . The protrusion 212 is a plate-shaped protrusion that extends along the outer surfaces 202 and 206. As shown in FIG. 21, when the regulating member 200 is fitted into the fitting part 400 and the regulating part 201 is engaged with the rack 71, the projection part 212 projects from the fitting part 400 in the -X direction. Thereby, for example, a service person can remove the regulating member 200 from the fitting part 400 by pinching the protrusion 212 and pulling it in the -X direction.

Further, 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 far side in the fitting direction of the space HK, and becomes further away from the inner surface 406 as it goes toward the +X direction. By providing the outer surface 207, the rear side of the regulating member 200 in the fitting direction is less likely to be caught in the fitting portion 400, so that the regulating member 200 can be easily fitted into the fitting portion 400. Outer surface 207 is an example of a non-contact surface.

Further, by providing the outer surface 207, as shown by the white arrow in FIG. 21, the regulating member 200 can be removed from the fitting part 400 while being rotated with the regulating part 201 side of the regulating member 200 as the center of rotation. It becomes possible. Note that when the regulating member 200 is fitted into the fitting part 400 and is in the space HK, the range in which the outer surface 206 of the regulating member 200 of this embodiment comes into contact with the inner surface 406 of the fitting part 400 is within the range of the regulating member in the X-axis direction. The restriction portion 201 of the cap portion 200 is set on the −X direction side with respect to the range in which the restriction portion 201 of the cap portion 62 engages with the rack 71 of the cap portion 62. Therefore, for example, when a service person pushes or pulls the protrusion 212 of the regulating member 200 in the -B direction, a moment is generated that causes the regulating member 200 to rotate as shown by the white arrow in FIG. can be generated.

As shown in FIGS. 16 to 18, the regulating member 200 includes a deformable portion 210, engaged portions 209 and 213, and a knob portion 211. In addition, for explanation, the knob 211 is also shown in FIG. 18 by a chain double-dashed line. The deformable portion 210 is integrally formed with the regulating member 200. The deformable portion 210 has a fixed end on the outer surface 204 side from the center of the regulating member 200 and has a thin plate shape extending toward the outer surface 205. Therefore, the deformable portion 210 is elastically deformable.
