[0007] 1. Embodiment 1 The printer 1 according to the first embodiment will be described in detail below as an example of a recording apparatus according to the present invention. A printer 1 is shown as an example of a recording device in Fig. 1. The printer 1 is configured as an inkjet type device that performs recording by ejecting ink, which is an example of a liquid, onto a medium P, which is typified by recording paper.

[0008] The printer 1 is assumed to be placed on a horizontal plane, and the XYZ coordinate system shown in each figure is an orthogonal coordinate system with three mutually orthogonal spatial axes as the X-axis, Y-axis, and Z-axis. The directions along the X-axis, Y-axis, and Z-axis are respectively the X-direction, Y-direction, and Z-direction, the positive directions toward the + side along the X-axis, Y-axis, and Z-axis are respectively the +X-direction, +Y-direction, and +Z-direction, the negative directions toward the - side along the X-axis, Y-axis, and Z-axis are respectively the -X-direction, -Y-direction, and -Z-direction, the Z-direction is the vertical direction, the upward direction along the vertical direction is the +Z-direction, and the downward direction along the vertical direction is the -Z-direction. The XY plane including the X-axis and Y-axis is a horizontal plane. The AB coordinate system, which is included in the XZ plane including the X-axis and Z-axis, and has two mutually orthogonal spatial axes as the A-axis and B-axis, is an orthogonal coordinate system. Additionally, the direction along the A axis is the A direction, the upward direction along the A axis is the +A direction, the opposite direction of the +A direction is the -A direction, the direction along the B axis is the B direction, the downward direction along the B axis is the +B direction, and the opposite direction of the +B direction is the -B direction.

[0009] The Y direction is the horizontal direction, which is the width direction of the medium P and the device depth direction that intersects with the transport direction of the medium P. The Y direction is also an example of the device depth direction that intersects with both the A direction and the B direction described below. The +Y direction is the direction toward the front in the Y direction, and the -Y direction is the direction toward the back in the Y direction. The X direction is the device width direction, and is horizontal. The +X direction is the direction toward the left in the X direction as seen by the operator of the printer 1, and the -X direction is the direction toward the right in the X direction. The Z direction is the height direction of the device.

[0010] In the printer 1, the medium P is transported through a transport path T indicated by a dashed line. The AB coordinate system shown on the XZ plane is an orthogonal coordinate system. The A direction is an example of the transport direction of the medium P in the area of ​​the transport path T facing the line head 20 described later. The direction toward the upstream of the A direction is called the -A direction, and the direction toward the downstream is called the +A direction. In this embodiment, the A direction is a direction inclined so that the +A direction side is located closer to the +Z direction side than the -A direction side. The B direction is an example of a moving direction, and is a moving direction in which the line head 20 described later moves forward and backward relative to the transport unit 10 described later. The direction in the B direction in which the line head 20 approaches the transport path T is called the +B direction, and the direction in which the line head 20 moves away from the transport path T is called the -B direction. In this embodiment, the B direction is a direction inclined so that the +B direction side is located closer to the +Z direction side than the -B direction side, and is perpendicular to the A direction.

[0011] Specifically, as shown in FIG. 2, when viewed from the Y direction, if the angle between the B direction and the X direction is the first angle θ1, the first angle θ1 is greater than 0 degrees and equal to or smaller than 45 degrees, specifically greater than 10 degrees and equal to or smaller than 40 degrees, more specifically 30 degrees. Also, if the angle between the A direction and the X direction is the third angle θ3, the third angle θ3 is equal to or greater than 45 degrees and smaller than 90 degrees, specifically greater than 50 degrees and equal to or smaller than 80 degrees, more specifically 60 degrees. Thus, the movement direction in which the line head 20 moves forward and backward relative to the transport unit 10 described later is an inclined direction intersecting both the horizontal and vertical directions. Also, the transport direction of the medium P in the area including the transport unit 10 where recording is performed by the line head 20 is an inclined direction intersecting both the horizontal and vertical directions.

[0012] As shown in FIG. 1, the printer 1 has a housing 2 as an example of a device main body. The housing 2 is placed on a horizontal plane. An ejection section 3 is formed in the +Z direction from the center of the housing 2 in the Z direction, forming a space into which the medium P on which information is recorded is ejected. In addition, a plurality of media cassettes 4 are provided in the -Z direction from the center of the housing 2 in the Z direction. The media cassettes 4 are an example of a media storage section. In addition, a manual feed tray 9 is provided in the center of the housing 2 in the Z direction so as to protrude from the housing 2 in the -X direction. In other words, the manual feed tray 9 is provided on the -X direction side of the transport path T. The manual feed tray 9, in which the medium P can be set, is used when recording on a medium P that cannot be set in the media cassette 4.

[0013] A plurality of media P are stacked and stored in the plurality of media cassettes 4. A pick roller 6 is provided in the media cassette 4 closer to the -X direction from the center so as to be able to contact the top surface of the media P. The pick roller 6 is located below the discharge unit 3. The media P stored in each media cassette 4 is sent from the media cassette 4 toward the transport path T in the -X direction by the pick roller 6. The media P sent by the pick roller 6 toward the transport path T is transported along the transport path T by the transport roller pair 7 and the transport roller pair 8. The transport path T includes a transport path T1 along which the media P is transported from an external device, and a transport path T2 that merges with the transport path T from the -X direction side. The transport path T2 can transport the media P set in the manual feed tray 9 to the transport path T. The manual feed tray 9 is located on the -X direction side of the position where the transport path T2 merges with the transport path T. This makes it easier to form the transport path T2 as a path with less curvature along the manual feed tray 9.

[0014] In addition, the transport path T is provided with a transport unit 10 (described later), multiple transport roller pairs 11 that transport the medium P, a registration roller pair 11A that corrects the inclination of the medium P, a discharge roller pair 11B, multiple flaps 12 that switch the path along which the medium P is transported, and a medium width sensor 13 that detects the width of the medium P in the Y direction.

[0015] The transport path T is curved in the area facing the medium width sensor 13, and extends obliquely upward from the medium width sensor 13, i.e., in the +A direction. A pair of registration rollers 11A is provided upstream of the transport unit 10 on the transport path T. The pair of registration rollers 11A is disposed on the -A direction side of the transport unit 10. The pair of registration rollers 11A corrects skew of the medium P being transported. Note that skew of the medium P refers to a state in which the posture of the medium P is inclined with respect to the transport direction.

[0016] Downstream of the transport unit 10 on the transport path T, there are provided transport paths T3 and T4 leading to the discharge section 3, and a reversing path T5 which reverses the medium P. A discharge roller pair 11B which discharges the medium P onto which ink has been discharged towards the discharge section 3 is arranged on the transport paths T3 and T4. The discharge roller pair 11B is provided at a position on the -X direction side with respect to the discharge section 3. The discharge roller pair 11B discharges the medium P in the +X direction. The medium P onto which ink has been discharged is discharged to the discharge section 3 and stacked.

[0017] Also provided within the housing 2 are an ink storage section 23 that stores ink, a waste liquid storage section 16 that can store waste ink, and a control section 26 that controls the operation of each section of the printer 1. The ink storage section 23 supplies ink to the line head 20 via a tube (not shown). As shown in FIG. 2, the waste liquid storage section 16 is connected to a first maintenance unit 62 (described later) via a flexible waste liquid tube 16A. The waste liquid storage section 16 is located below the first maintenance unit 62. The waste liquid storage section 16 collects ink for maintenance discharged from the line head 20 toward the first maintenance unit 62 (described later) via the waste liquid tube 16A and stores it as waste liquid.

[0018] The control unit 26 is configured to include a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage (not shown), and controls the transportation of the medium P in the printer 1 and the recording operation of information on the medium P by the line head 20.

[0019] 2, the discharge section 3 is provided with a discharge tray 21 in line with the transport paths T3 and T4. The discharge tray 21 constituting the bottom of the discharge section 3 is a plate-shaped member as an example of a mounting member, and has a mounting surface 21A on which the discharged medium P is placed. The discharge tray 21 is provided downstream of a transport unit 10 (described later) in the transport path T of the medium P and in the +Z direction with respect to a line head 20 (described later) in the Z direction.

[0020] Specifically, discharge tray 21 extends in an oblique direction so that the portion on the +X side is located further in the +Z direction than the portion on the -X side. In other words, the downstream end of discharge tray 21 is located further in the +Z direction than the upstream end in the transport direction of medium P. Placement surface 21A has an inclination that slopes obliquely upward along the discharge direction of medium P.

[0021] 2, when viewed from the Y direction, the angle formed between the inclination direction of the placement surface 21A and the X direction is defined as a second angle θ2. The second angle θ2 is expressed as the angle formed between the placement surface 21A and a virtual plane K along the X direction. In this embodiment, the second angle θ2 is, for example, smaller than the first angle θ1.

[0022] The printer 1 has, as its essential parts, a transport unit 10 that transports the medium P, a line head 20 that records information on the medium P, and a head moving unit 30 that moves the line head 20 in the B direction.

[0023] As shown in FIG. 1 and FIG. 2, the transport unit 10 has two pulleys 14, an endless transport belt 15 wound around the two pulleys 14, and a motor (not shown) that drives the pulleys 14. The transport unit 10 is an example of a support unit. The support surface of the transport belt 15 that supports the medium P constitutes a part of the transport path T. As shown in FIG. 2, the outer dimension D1 in the X direction of the transport belt 15 wound around the two pulleys 14 is smaller than the dimension D2 in the A direction of the support surface of the transport belt 15 that supports the medium P. In other words, among the outer dimensions in the horizontal direction of the transport belt 15 wound around the two pulleys 14, the outer dimension D1 in the direction perpendicular to the width direction of the transport belt 15 is smaller than the dimension D2 in the A direction of the support surface of the transport belt 15 that supports the medium P. The medium P is transported to a position facing the line head 20 while being adsorbed to the support surface of the transport belt 15. For this reason, as shown in FIG. 2, a charging roller 17 for charging the transport unit 10 and a charge removing brush 18 for removing charge from the medium P supported by the transport unit 10 are provided within the housing 2.

[0024] The charging roller 17 is an example of a charging section. The charging roller 17 charges the conveyor belt 15 by contacting the conveyor belt 15. The charging roller 17 charges the conveyor belt 15, thereby attracting the medium P to the support surface of the conveyor belt 15. The charging roller 17 is provided at a position on the +B direction side of the endless conveyor belt 15 wound around two pulleys 14. The charging roller 17 may be provided at a position where the conveyor belt 15 is sandwiched between the charging roller 17 and the pulley 14 located on the -A direction side of the two pulleys 14.

[0025] The charging roller 17 is in contact with the support surface of the conveyor belt 15, and rotates in response to the operation of the conveyor belt 15. A power supply device (not shown) that applies a DC voltage to the charging roller 17 is connected to the charging roller 17, and this causes the charging roller 17 to supply charge to the portion in contact with the conveyor belt 15. The power supply device is controlled by a control unit 26, which switches on and off the application of voltage to the charging roller 17 and switches the voltage applied to the charging roller 17. In this embodiment, the charging roller 17 supplies a positive charge to the conveyor belt 15, and charges the support surface of the conveyor belt 15 to a positive polarity.

[0026] The static elimination brush 18 is an example of a static elimination section. The static elimination brush 18 comes into contact with the medium P supported by the conveyor belt 15 to eliminate static electricity from the medium P. The static elimination brush 18 is provided at a position on the -B direction side with respect to the endless conveyor belt 15 wound around two pulleys 14. The static elimination brush 18 is provided at a position on the -A direction side with respect to the ejection surface NA of the line head 20. The static elimination brush 18 may be provided at a position where the conveyor belt 15 is sandwiched between the static elimination brush 18 and the pulley 14 located on the -A direction side of the two pulleys 14.

[0027] The static electricity removal brush 18 removes the charge from the recording surface of the medium P, which is the ejection surface NA side. Alternatively, the static electricity removal brush 18 may remove the charge from the support surface of the transport belt 15. More specifically, when a charge is applied to the support surface of the transport belt 15 by the charging roller 17, a charge of the opposite polarity is generated on the surface of the medium P in contact with the support surface, and a charge of the opposite polarity is also generated on the opposite surface of the medium P, i.e., the recording surface. The charge on the recording surface side is removed by the static electricity removal brush 18. As a result, only the charge on the side of the medium P in contact with the transport belt 15 remains, and as a result, the medium P is attracted to the support surface.

[0028] The static electricity removal brush 18 may be made of any material that can remove electric charges from the medium P and the transport belt 15, and may be made of, for example, a resin material such as conductive nylon. The static electricity removal brush 18 is connected to a switching device (not shown), and the switching device is controlled by the control unit 26 to switch the static electricity removal brush 18 between a grounded state and a non-grounded state.

[0029] In this way, the conveyor belt 15 supports the medium P while adsorbing the medium P. The support surface of the conveyor belt 15 that supports the medium P constitutes an area of ​​the conveying path T that faces the line head 20. That is, the conveyor unit 10 rotates when the pulley 14 is driven, and conveys the medium P supported on the support surface of the conveyor belt 15 in the +A direction in the conveying direction. At this time, the downstream side in the conveying direction is higher than the upstream side in the conveying direction. The conveyor unit 10 is also disposed opposite the line head 20 in the B direction. As a method for adsorbing the medium P to the conveyor belt 15, an adsorption method such as an air suction method may be adopted.

[0030] The transport unit 10 may further include a driven roller 19 that suppresses the medium P from floating off the support surface of the transport belt 15. In this case, the driven roller 19 is provided at a position on the -B direction side with respect to the endless transport belt 15 wound around two pulleys 14. The driven roller 19 is provided at a position between the discharge surface NA of the line head 20 and the charge removal brush 18 in the A direction. The driven roller 19 is provided at a position where the medium P is sandwiched between the driven roller 19 and the transport belt 15, and is rotated in response to the movement of the medium P supported by the transport belt 15. The driven roller 19 may be made of a conductive material such as a metal and may be grounded.

[0031] The line head 20 is an example of a head unit. The line head 20 has nozzles N that eject ink, which is an example of liquid. The line head 20 is disposed opposite the transport unit 10 in the B direction at a recording position described later, and records information by ejecting ink from the nozzles N onto the medium P transported in the transport direction. The line head 20 is an ink ejection head configured so that the nozzles N that eject ink cover the entire area in the Y direction, which is the width direction of the medium P. The ejection surface NA on which the nozzles N are disposed is disposed along the A direction and the Y direction. As shown in FIG. 2, the ejection surface NA faces the +B direction. The dimension of the ejection surface NA in the Y direction is larger than the dimension of the ejection surface NA in the A direction. The ejection surface NA faces the +A direction side of the center of the support surface of the transport belt 15 that supports the medium P. That is, the line head 20 is located on the +A direction side of the center of the support surface of the transport belt 15 that supports the medium P in the A direction.

[0032] Moreover, the line head 20 is configured as an ink ejection head capable of recording over the entire width of the medium P without moving in the width direction of the medium P. However, the type of ink ejection head is not limited to this, and it may be a type that is mounted on a carriage and ejects ink while moving in the width direction of the medium P.

[0033] As shown in Fig. 4, the line head 20 extends in the Y direction. Plate portions 20A protrude in the +A direction from the +A direction sides of both ends of the line head 20 in the Y direction. Support frames 22 are attached to both ends of the line head 20 in the Y direction. A second maintenance unit 72 shown in Fig. 4 will be described later.

[0034] The support frame 22 is configured as a side plate along the AB surface, and extends in the -B direction with respect to the line head 20. Cylindrical support pins 24 extending in the +Y and -Y directions are provided on both ends in the B direction of the outer surface in the Y direction of the support frame 22. An annular roller 25 is rotatably provided on the support pin 24.

[0035] Further, a support pin 27, a rack 28, and a coil spring 29 are provided on the inner surface of the support frame 22 in the Y direction. The support pin 27 protrudes from the support frame 22 in the Y direction.

[0036] Rack 28 is a plate-like member whose thickness direction is in the Y direction, and extends in the B direction. A plurality of teeth 28A aligned in the B direction are formed at the end of rack 28 in the -A direction. Rack 28 also has a long hole 28B that penetrates in the Y direction and is long in the B direction. Support pin 27 is inserted into long hole 28B. This allows rack 28 to move in the B direction relative to support frame 22.

[0037] One end of the coil spring 29 is attached to the support frame 22. The other end of the coil spring 29 is attached to the rack 28. This allows the coil spring 29 to exert an elastic force on the rack 28 in the B direction.

[0038] The line head 20 can be detached from the head moving part 30 shown in Fig. 3 at an exchange position indicated by a two-dot chain line in Fig. 1. The exchange position is a position furthest from the transport unit 10 in the -B direction in the movement direction of the line head 20. Specifically, the line head 20 is detached from the head moving part 30 by the support frame 22 being moved in the -B direction along a guide rail 37 described later, and then being pulled up in the +Z direction along a guide rail 38.

[0039] The head moving unit 30 moves the line head 20 along direction B to a recording position and a retracted position, which will be described later. In other words, the head moving unit 30 moves the line head 20 in direction B so that the moving direction of the line head 20 intersects with both the vertical and horizontal directions. The moving direction is an inclined direction that intersects with the horizontal plane at an angle greater than 0 degrees and equal to or less than 45 degrees, and specifically, the angle at which the moving direction intersects with the horizontal plane is 30 degrees.

[0040] 3 and 5, the head moving unit 30 has a main body frame 32 constituting a main body portion, a guide member 36 that guides the line head 20 in the B direction, and a drive unit 40 that drives the line head 20 in the B direction, which will be described later. The head moving unit 30 moves the line head 20 to one or more retracted positions, which will be described later, that are away from the transport unit 10 with respect to a recording position, which will be described later. Specifically, the head moving unit 30 is provided so as to be able to move the line head 20 to a first position, a second position, and a third position. The first position, the second position, and the third position will be described later.

[0041] The main body frame 32 is included in the housing 2. That is, the main body frame 32 is included in an example of the device main body. Specifically, the main body frame 32 has a side frame 33, a side frame 34, and a plurality of horizontal frames 35.

[0042] The side frame 33 and the side frame 34 are each configured as a side plate along the AB plane, and are disposed facing each other with a gap in the Y direction. The side frame 33 is disposed on the +Y direction side, and the side frame 34 is disposed on the -Y direction side. A through hole 34A is formed in the side frame 34 for movement of a second maintenance unit 72, which will be described later. A plurality of horizontal frames 35 connect the side frame 33 and the side frame 34 in the Y direction. A line head 20 is disposed in a space surrounded by the plurality of horizontal frames 35.

[0043] Guide member 36 is an example of a guide portion, and one guide member 36 is provided on each of side frames 33 and 34. The two guide members 36 are disposed approximately symmetrically with respect to the center in the Y direction of main body frame 32. For this reason, only guide member 36 in the -Y direction will be described, and a description of guide member 36 in the +Y direction will be omitted.

[0044] As shown in Fig. 5, guide member 36 is attached to the side surface of side frame 34 in the +Y direction. Guide member 36 is formed with guide rail 37 extending in the B direction and guide rail 38 branching off from a midpoint of guide rail 37 and extending in the Z direction. Both guide rail 37 and guide rail 38 are grooves that open in the +Y direction. Furthermore, guide rail 37 and guide rail 38 guide roller 25 in the B direction or the Z direction.

[0045] As shown in FIG. 5, the side frame 34 is provided with a guide rail 71 constituting a cap moving section 80 described later. The guide rail 71 is also provided on the side frame 33. That is, a set of guide rails 71 is provided between the side frame 33 and the side frame 34. The set of guide rails 71 is formed in a groove shape that opens toward the inside in the Y direction and extends along the A direction. The set of guide rails 71 also supports a plurality of rollers 73 described later so that the rollers 73 can move in the A direction. That is, the guide rails 71 guide the rollers 73 in the A direction, thereby enabling a first maintenance unit 62 described later to move in the A direction.

[0046] As shown in Fig. 5, the drive unit 40 includes a motor 41, a gear portion (not shown), a shaft 42, and a pinion 43, and the drive is controlled by the control portion 26. The shaft 42 extends in the Y direction. Both ends of the shaft 42 are rotatably supported by the side frames 33 and 34 shown in Fig. 3. The pinion 43 is attached to both ends of the shaft 42 in the Y direction. The pinion 43 has teeth 43A formed on its outer periphery to mesh with the teeth 28A.

[0047] The motor 41 rotates the shaft 42 and the pinion 43 in one direction or the opposite direction via a gear unit (not shown). In this manner, the drive unit 40 rotates the pinion 43 to move the line head 20 in the B direction.

[0048] As shown in FIG. 6, the printer 1 has a maintenance unit 60, a cap moving unit 80, a lid unit 90, and a rotation mechanism unit 100.

[0049] The maintenance unit 60 is an example of a storage section that stores the nozzles N and performs maintenance on the nozzles N. Specifically, the maintenance unit 60 has a first maintenance unit 62 that can cover the nozzles N, and a second maintenance unit 72 that cleans the ink ejection surface NA of the nozzles N by wiping it. The second maintenance unit 72 will be described later.

[0050] The first maintenance unit 62 is an example of a capping unit. The first maintenance unit 62 includes a capping unit main body 63, a cap 64 that covers the nozzle N, and a flushing unit 66 that faces the nozzle N and receives ink ejected from the nozzle N. The first maintenance unit 62 includes the cap 64 and the flushing unit 66 along the A direction, and moves in the A direction to switch between a state in which the cap 64 faces the nozzle N and a state in which the flushing unit 66 faces the nozzle N. The first maintenance unit 62 has a standby position on the -A direction side of the line head 20, and has a standby position, an ejection position, and a capping position in that order toward the +A direction.

[0051] The standby position is away from the cap position in the -A direction in the A direction. That is, the standby position is away from the line head 20 with respect to the cap position, and is located lower than the cap position. This makes it easy to arrange the waste liquid tube 16A connecting the first maintenance unit 62 and the waste liquid storage section 16 lower than the line head 20. Therefore, the waste liquid tube 16A is less likely to interfere with the line head 20 or the transport path T. Also, since the waste liquid tube 16A is less likely to be bent at the cap position, the waste liquid from the first maintenance unit 62 is easily collected in the waste liquid storage section 16.

[0052] The ejection position is the position of the first maintenance unit 62 when the flushing unit 66 faces the nozzle N. The ejection position is away from the standby position in the +A direction in the A direction. The cap position is the position of the first maintenance unit 62 when the cap 64 covers the ejection surface NA. The first maintenance unit 62 in the cap position is located between the line head 20 and the transport unit 10 in the B direction. The cap position is away from the ejection position in the -A direction in the A direction.

[0053] As shown in FIG. 7, the cap body 63 is formed in a box shape whose dimension in the Y direction is larger than its dimension in the A direction. The cap body 63 has an opening 65 that opens in the -B direction. A rack 69 extending in the A direction is provided on each of the side walls 63A of the cap body 63 in the +Y direction and the -Y direction. The rack 69 has a plurality of teeth 69A aligned in the A direction. In addition, both side walls 63A are provided with a plurality of rollers 73 that are rotatable about the Y direction as their axial direction. A partition wall 67 is provided on the inside of the cap body 63. The partition wall 67 divides the space in the cap body 63 into a space in the +A direction and a space in the -A direction. The cap 64 is disposed in the space in the -A direction of the partition wall 67, and the flushing part 66 is disposed in the space in the +A direction of the partition wall 67.

[0054] The cap 64 of the first maintenance unit 62 has a cap surface 64A that covers the ejection surface NA. The cap 64 has a recessed portion 64B that opens into the cap surface 64A. The size and shape of the cap surface 64A are set to cover the ejection surface NA. Therefore, when the cap surface 64A at the cap position is viewed from the -B direction side, the dimension D3 of the cap surface 64A in the Y direction is larger than the dimension D4 of the cap surface 64A in the A direction. Also, when the first maintenance unit 62 at the cap position is viewed from the B direction, the dimension of the first maintenance unit 62 in the Y direction is larger than the dimension of the first maintenance unit 62 in the A direction. Here, the standby position of the first maintenance unit 62 is provided at a position spaced apart from the cap position in the A direction. This allows the distance between the standby position and the cap position to be narrower than when the standby position is provided at a position spaced apart from the cap position in the Y direction, making it easier to reduce the installation area of ​​the printer 1.

[0055] Furthermore, the cap 64 covers the ejection surface NA by arranging the cap surface 64A facing the ejection surface NA in the direction B. That is, in the cap position, the first maintenance unit 62 covers the ejection surface NA, thereby suppressing drying of the nozzles N and suppressing an increase in the viscosity of the ink. Note that the cap 64 is capable of covering the nozzles N when the line head 20 is located in the retracted position. That is, the first maintenance unit 62 does not cover the ejection surface NA in the standby position and the ejection position.

[0056] The flushing part 66 is an example of a receiving part, and is provided inside the opening 65. The flushing part 66 is disposed on the +A direction side of the cap 64 in the A direction. In other words, when the first maintenance unit 62 is disposed in the standby position, the flushing part 66 is disposed at a position closer to the line head 20 than the cap 64 in the A direction.

[0057] The flushing section 66 is configured as a flushing box that is open in the -B direction and has porous fibers such as felt. The flushing section 66 captures the ink ejected from the nozzle N. When the viscosity of the ink increases in the nozzle N, the ink is ejected toward the flushing section 66, thereby maintaining the viscosity of the ink within a set range. This prevents poor ink ejection from the nozzle N.

[0058] The second maintenance unit 72 is an example of a cleaning unit. The second maintenance unit 72 includes a main body 74 and a blade 76. The main body 74 is formed in a box shape that opens in the -B direction. The blade 76 is, for example, made of a rectangular plate-like rubber. The blade 76 is provided on the main body 74 with a portion that wipes the nozzle N protruding from the main body 74 in the -B direction and inclined with respect to the A direction and the Y direction.

[0059] The second maintenance unit 72 can be advanced and retreated in the Y direction between a retreat position in the -Y direction with respect to the side frame 34 and a cleaning position for cleaning the ejection surface NA by a blade movement unit (not shown). The Y direction is an example of a second direction in which the blade movement unit advances and retreats the second maintenance unit 72. The maximum movement amount D12 of the second maintenance unit 72 in the Y direction is the distance in the Y direction between the retreat position shown by the solid line in FIG. 4 and the position shown by the two-dot chain line that is the furthest from the retreat position. The second maintenance unit 72 in the cleaning position is located between the line head 20 and the transport unit 10 in the B direction. The drive unit (not shown) is configured to include, as an example, a motor and a belt to which the second maintenance unit 72 is attached, and the second maintenance unit 72 is moved in the Y direction by the belt being moved in a circular motion by the rotation of the motor. Note that the second maintenance unit 72 is retreated to the retreat position when the first maintenance unit 62 covers the line head 20 and when the line head 20 performs recording.

[0060] The cap moving part 80 moves the first maintenance unit 62 in the A direction between the cap position and the standby position. The A direction is an example of a first direction in which the cap moving part 80 moves the first maintenance unit 62 forward and backward. The first direction is an inclined direction that intersects with the horizontal plane at an angle of 45 degrees or more and less than 90 degrees, and specifically, the angle at which the first direction intersects with the horizontal plane is 60 degrees. Therefore, the first direction has a larger inclination than the moving direction. As shown in FIG. 2, the cap moving part 80 moves the first maintenance unit 62 on the -B direction side with respect to the charge removal brush 18. This makes it possible to narrow the gap in the A direction between the registration roller pair 11A and the line head 20. Therefore, it is possible to perform recording by the line head 20 on the medium P with less skew after passing through the registration roller pair 11A. In addition, the cap moving part 80 moves the first maintenance unit 62 in the A direction on the -B direction side with respect to the registration roller pair 11A. The cap moving part 80 supports the first maintenance unit 62 in a state in which the cap surface 64A of the cap 64 faces the -B direction. The state in which the cap surface 64A faces the -B direction is an example of a state in which the cap surface 64 faces a direction between the X direction and the +Z direction. Specifically, the cap moving part 80 has a gear 82 having teeth 82A that mesh with teeth 69A of the rack 69, a motor 84 that rotates the gear 82, and a guide rail 71 shown in FIG. 6 that supports the roller 73 of the first maintenance unit 62. The drive control of the cap moving part 80 is performed by the control part 26.

[0061] When the line head 20 is located at a retracted position, which will be described later, the cap moving section 80 advances the first maintenance unit 62 between the line head 20 at the retracted position and the transport unit 10. In addition, before the line head 20 is located at a recording position, which will be described later, the cap moving section 80 retracts the first maintenance unit 62 in the -A direction from between the line head 20 at the retracted position and the transport unit 10.

[0062] The lid unit 90 is an example of a lid portion. The lid unit 90 is formed in a rectangular parallelepiped shape that is long in the Y direction as a whole, and is rotatable around a rotation axis that extends in the Y direction. At the ejection position, the lid unit 90 is located on the +A direction side of the line head 20 in the A direction. When the cap 64 covers the nozzle N, the lid unit 90 takes a closed position that covers the flushing portion 66.

[0063] The rotation mechanism 100 is a mechanism that rotates the lid unit 90 around a rotation axis. When the head moving unit 30 moves the line head 20 from a recording position to a retracted position, the rotation mechanism 100 rotates the lid unit 90 so that the lid unit 90 assumes a closed position.

[0064] Next, each position in direction B when the line head 20 shown in FIG. 2 is moved by the head moving unit 30, and the position of the maintenance unit 60 will be described.

[0065] 8, the recording position of the line head 20 means the stopping position of the line head 20 when the line head 20 is capable of recording information on the medium P. When the line head 20 is in the recording position, the first maintenance unit 62 is in the standby position, and the second maintenance unit 72 is in the retracted position.

[0066] The retreat position of the line head 20 means a stop position of the line head 20 when the line head 20 moves away from the recording position in the -B direction from the transport unit 10. The retreat positions of the line head 20 include a first position, a second position, a third position, a head standby position, and a replacement position, which will be described later.

[0067] 9, the first position of the line head 20 refers to the position of the line head 20 in the B direction when the first maintenance unit 62 covers the nozzles N. When the line head 20 is in the first position, the first maintenance unit 62 is in the cap position, and the second maintenance unit 72 is in the retracted position. When viewed from the Z direction, the line head 20 in the first position and the first maintenance unit 62 in the cap position at least partially overlap. Also, when viewed from the Z direction, the first maintenance unit 62 in the cap position and the transport unit 10 at least partially overlap.

[0068] 10, the second position of the line head 20 refers to a position of the line head 20 when the flushing unit 66 faces the nozzles N at a greater distance in direction B than at the first position. Note that in the second position, the flushing unit 66 may be spaced apart from the nozzles N. When the line head 20 is in the second position, the first maintenance unit 62 is in the ejection position, and the second maintenance unit 72 is in the retracted position.

[0069] 11, the third position of the line head 20 refers to the position of the line head 20 in the direction B when the second maintenance unit 72 is able to clean the ejection surface NA of the nozzle N. When the line head 20 is in the third position, the first maintenance unit 62 is in the standby position, and the second maintenance unit 72 is able to move in the Y direction between the retracted position and the cleaning position.

[0070] As shown in FIG. 12 and FIG. 13, the head standby position of the line head 20 means a position in the B direction where the line head 20 is farther away from the transport unit 10 in the −B direction than the first position, the second position, and the third position. This is a position where the line head 20 waits until the first maintenance unit 62 and the second maintenance unit 72 complete their movement when they move. When the line head 20 is in the head standby position and the first maintenance unit 62 moves in the A direction, the second maintenance unit 72 is in the retracted position. Also, when the second maintenance unit 72 moves in the Y direction, the first maintenance unit 62 is in the standby position. Note that, as shown in FIG. 12, the movement amount D5 in the B direction by the head moving unit 30 to move the line head 20 from the recording position indicated by the ejection surface NA indicated by the two-dot chain line to the head standby position indicated by the solid line is set to be larger than the sum of the dimension D6 of the first maintenance unit 62 in the B direction and the dimension D7 of the charge removal brush 18 in the B direction.

[0071] As shown in FIG. 14, the replacement position of the line head 20 means a position where the line head 20 is further away from the transport unit 10 in the -B direction than the head standby position in the B direction. In other words, the replacement position of the line head 20 is the farthest position from the transport unit 10 in the B direction. When the line head 20 is attached to or detached from the head moving part 30 at the replacement position, the first maintenance unit 62 is at the standby position, and the second maintenance unit 72 is at the retracted position. At this time, the first maintenance unit 62 at the standby position is located vertically below the ejection surface NA of the line head 20 at the replacement position. This makes it possible to prevent the dropped ink from adhering to the transport path T, for example, when ink falls from the ejection surface NA when the line head 20 is attached or detached.

[0072] In this way, the head moving unit 30 is provided so as to be able to move the line head 20 to any one of the positions of the recording position, the retracted position, the first position, the second position, the third position, the head standby position, and the replacement position, for example. Also, the head moving unit 30 is configured to position the line head 20 at the head standby position before positioning the line head 20 at any one of the first position, the second position, and the third position.

[0073] 14, the distance in direction B between the recording position indicated by the ejection surface NA of the line head 20 in the two-dot chain line and the replacement position indicated by the solid line is the maximum movement amount D9 of the line head 20 in the direction B. The distance in direction A between the standby position indicated by the solid line of the first maintenance unit 62 and the cap position indicated by the end of the rack 69 in the two-dot chain line is the maximum movement amount D8 of the first maintenance unit 62 in the direction A. In this embodiment, the maximum movement amount D8 of the first maintenance unit 62 in the direction A is the same as or greater than the maximum movement amount D9 of the line head 20 in the direction B.

[0074] 12 is greater than the sum of the outer dimension D11 of the line head 20 in the B direction and the maximum movement amount D9 of the line head 20 in the B direction shown in FIG. 12. The maximum movement amount D12 of the second maintenance unit 72 in the Y direction is the same as or greater than the maximum movement amount D8 of the first maintenance unit 62 in the A direction. The mass of the first maintenance unit 62 is the same as or smaller than the mass of the line head 20. The mass of the second maintenance unit 72 is the same as or smaller than the mass of the first maintenance unit 62.

[0075] As described above, the printer 1 according to the first embodiment can provide the following advantages.

[0076] The printer 1 includes a transport unit 10 having a support surface that constitutes a transport path T and that transports a medium P supported on the support surface in a transport direction, a line head 20 having an ejection surface NA that faces the +B direction and is provided with nozzles N that eject ink onto the medium P transported in the transport direction, a first maintenance unit 62 that is capable of covering the ejection surface NA, a head moving section 30 that moves the line head 20 in the movement direction, and a cap 64A that supports the first maintenance unit 62 and has a cap surface 64A of the first maintenance unit 62 that covers the ejection surface NA. and a cap moving section 80 that moves the first maintenance unit 62 between a cap position and a standby position where the cap surface 64A does not cover the ejection surface NA, and when the cap surface 64A at the cap position is viewed from the B direction, a dimension D3 of the cap surface 64A in the Y direction is larger than a dimension D4 of the cap surface 64A in the A direction, the standby position is away from the cap position in the transport direction, and the cap moving section 80 supports the first maintenance unit 62 with the cap surface 64A facing an inclined direction between the X direction and the +Z direction. According to this, since the cap surface 64A faces an inclined direction between the X direction and the +Z direction, the horizontal dimension of the cap surface 64A can be made smaller than when the cap surface 64A faces vertically upward. Therefore, the installation area of ​​the printer 1 can be made smaller.

[0077] The transport direction is direction A, the movement direction is direction B, and the cap movement part 80 supports the first maintenance unit 62 with the cap surface 64A facing the -B direction and moves it in the A direction. According to this, since the first maintenance unit 62 moves in the A direction with the cap surface 64A facing the -B direction, the first maintenance unit 62 can cover the ejection surface NA while the ejection surface NA remains facing the +B direction. Therefore, it is easy to stabilize the meniscus formed in the nozzle N.

[0078] The printer 1 further includes a charging roller 17 that charges the support surface of the transport unit 10, and a static electricity removal brush 18 that is disposed on the -B direction side of the transport unit 10 and removes static electricity from the medium P supported by the transport unit 10, and the cap moving section 80 moves the first maintenance unit 62 on the -B direction side of the static electricity removal brush 18. As a result, the first maintenance unit 62 moves on the -B direction side of the static electricity removal brush 18, and therefore there is no need to move the static electricity removal brush 18 to avoid interference between the static electricity removal brush 18 and the first maintenance unit 62.

[0079] The amount of movement in direction B by the head moving part 30 to move the line head 20 is greater than the sum of the dimension of the first maintenance unit 62 in direction B and the dimension of the static electricity removal brush 18 in direction B. As a result, the ejection surface NA can be covered by the cap surface 64A by the movement of the line head 20 in direction B and the movement of the first maintenance unit 62 in direction A.

[0080] The first maintenance unit 62 is connected to the waste liquid storage section 16 capable of storing waste liquid via a waste liquid tube 16A, and the standby position is lower than the cap position, and the waste liquid storage section 16 is lower than the first maintenance unit 62. This makes it easy to collect the waste liquid from the first maintenance unit 62 in the waste liquid storage section 16.

[0081] The transport unit 10 transports the medium P in the +A direction and further includes a pair of registration rollers 11A arranged on the -A direction side of the transport unit 10, and the cap moving section 80 moves the first maintenance unit 62 in the A direction on the -B direction side of the pair of registration rollers 11A. This makes it possible to narrow the gap in the A direction between the pair of registration rollers 11A and the line head 20. Therefore, recording can be performed by the line head 20 on the medium P with little skew after passing through the pair of registration rollers 11A.

[0082] The printer 1 further includes a pick roller 6 that sends the medium P stored in the medium cassette 4 out of the medium cassette 4 in the -X direction, and a discharge roller pair 11B that discharges the medium P in the +X direction toward the discharge section 3 that stacks the medium P on which ink has been ejected. This makes it easy to concentrate the transport path of the medium P from the medium cassette 4 to the discharge section 3 on the -X direction side of the housing 2. This makes it easy to arrange the line head 20 and the first maintenance unit 62 on the +X direction side of the housing 2, making it easy to make the printer 1 smaller.

[0083] The printer 1 further includes a manual tray 9 provided on the -X side of a transport path T along which the medium P sent to the pick roller 6 is transported via the transport unit 10 towards the discharge unit 3, and a transport path T2 that merges with the transport path T from the -X side and is capable of transporting the medium P set in the manual tray 9 to the transport path T. This makes it easy to concentrate the transport path to the discharge unit 3, including the transport of the medium P from the manual tray 9, on the -X side of the housing 2. This makes it easy to make the printer 1 more compact.

[0084] 2. Embodiment 2 Next, a printer 501 according to a second embodiment will be described as an example of a recording apparatus according to the present invention. Note that parts common to the printer 1 according to the first embodiment will be given the same reference numerals and their description will be omitted. Furthermore, description of the same functions and effects as those of the first embodiment will also be omitted.

[0085] As shown in FIG. 15, in a printer 501, the maintenance unit 60 and the cap moving unit 80 in the first embodiment are changed to a maintenance unit 560 and a cap moving unit 580.

[0086] The maintenance unit 560 is obtained by replacing the first maintenance unit 62 of the maintenance unit 60 in the first embodiment with a first maintenance unit 562. The first maintenance unit 562 is obtained by replacing the cap part main body 63 of the first maintenance unit 62 in the first embodiment with a cap part main body 563, and removing the flushing part 66 from the first maintenance unit 62. For this reason, the printer 501 does not include the lid unit 90 and the rotation mechanism part 100 in the first embodiment.

[0087] The cap part main body 563 is obtained by changing the rack 69 of the cap part main body 63 in the first embodiment to a rack 569. Therefore, a plurality of teeth 69A (not shown) of the rack 569 are arranged in an arc shape. Furthermore, in this embodiment, the cap 64 captures ink ejected from the nozzle N at the cap position shown by the two-dot chain line in Fig. 15. Therefore, the ejection position of the first maintenance unit 562 is the same as the cap position.

[0088] The cap moving part 580 is obtained by changing the guide rail 71 of the cap moving part 80 in the first embodiment to a guide rail 571. As shown in Fig. 15, the guide rail 571 movably supports the rollers 73 of the first maintenance unit 562. The guide rail 571 has an arc shape. Therefore, the guide rail 571 guides the rollers 73, so that the first maintenance unit 562 can rotate about a rotation axis SC parallel to the Y axis shown in Fig. 15.

[0089] Therefore, at the standby position, the direction in which the cap surface 64A of the first maintenance unit 562 faces is an inclined direction between the X direction and the +Z direction, but different from the -B direction. If the angle between the direction in which the cap surface 64A faces and the X direction at the standby position is set to a fourth angle θ4 shown in FIG. 15, the fourth angle θ4 is greater than the first angle θ1 which is the angle between the B direction and the X direction. In addition, the angle between the direction in which the cap surface 64A of the first maintenance unit 562 faces and the X direction changes from the fourth angle θ4 to the first angle θ1 during the process of moving from the standby position to the cap position.

[0090] As described above, the printer 501 according to the second embodiment includes a transport unit 10 that configures a transport path T and transports a medium P in a transport direction between the X direction and the A direction, a line head 20 having an ejection surface NA facing the +B direction and provided with nozzles N that eject ink onto the medium P transported in the transport direction, a first maintenance unit 562 that is capable of covering the ejection surface NA, a head moving section 30 that moves the line head 20 in the movement direction, and a cap surface 64A of the first maintenance unit 562 that supports the first maintenance unit 562 and covers the ejection surface NA. and a cap moving section 580 which moves the first maintenance unit 562 between a cap position where it covers the ejection surface NA and a standby position where the cap surface 64A does not cover the ejection surface NA, wherein when the cap surface 64A in the cap position is viewed from direction B, a dimension D3 of the cap surface 64A in the Y direction is larger than a dimension D4 of the cap surface 64A in the A direction, the standby position is away from the cap position in the transport direction, and the cap moving section 580 supports the first maintenance unit 562 with the cap surface 64A facing in an inclined direction between the X direction and the +Z direction.

[0091] The printer 1 according to the first embodiment and the printer 501 according to the second embodiment of the present invention are basically configured as described above, but it is of course possible to modify or omit parts of the configuration without departing from the scope of the present invention. Furthermore, the above embodiment and the other embodiments described below can be combined with each other as long as they are not technically inconsistent. The other embodiments will be described below.

[0092] The first angle θ1 may be the same as the second angle θ2, or may be smaller than the second angle θ2.

[0093] The printer 1 does not necessarily have to have the second maintenance unit 72. Also, the printer 1 does not necessarily have to have the lid unit 90.

[0094] The printer 1 may be one in which the line head 20 is attached and detached in the Y direction.

[0095] In the printer 1, the flushing part 66 of the first maintenance unit 62 may be disposed on the -A direction side of the cap 64 in the A direction.

[0096] The head moving section 30 may not position the line head 20 at the standby position before positioning the line head 20 at any one of the first position, the second position, and the third position.

[0097] In the printer 1, the direction in which the cap surface 64A faces may change during the process in which the first maintenance unit 62 moves in the A direction. In this case, the cap moving section 80 may support the first maintenance unit 62 with the cap surface 64A facing in an inclined direction between the X direction and the +Z direction, and move it in the A direction.

[0098] In the printer 1, the first direction does not have to be perpendicular to the movement direction. For example, when the movement direction is direction B, and the first angle θ1 between direction B and direction X is 30 degrees, the angle between the first direction and direction X may be 70 degrees. In this case, the transport direction may or may not be direction A. If the transport direction is not direction A, the transport direction may be along the first direction, and the angle between the transport direction and direction X may be 70 degrees.

[0099] In the printer 1, the first maintenance unit 62 may move on a circular arc. In this case, the cap moving part 80 may support the first maintenance unit 62 by a link mechanism. Furthermore, when the cap moving part 80 moves the first maintenance unit 62 by driving the link mechanism, the rack 69 does not need to be provided on the cap part main body 63.

[0100] In the printer 1, the transport direction does not have to be perpendicular to the +B direction in which the ejection surface NA faces. For example, the transport direction of the medium P in the region where the line head 20 and the transport unit 10 face each other may be the X direction.
