DETAILED DESCRIPTION

[0024] 1. Implementation Method 1

[0025] Hereinafter, a printer 1 according to Embodiment 1 will be described in detail as an example of a recording device according to the present invention.

[0026] Figure 1 2 shows a printer 1 as an example of a recording device. The printer 1 is configured as an inkjet device that performs recording by ejecting ink as an example of liquid onto a medium P represented by recording paper.

[0027] Assuming that the printer 1 is placed on a horizontal plane, the XYZ coordinate system shown in each figure is an orthogonal coordinate system with three mutually orthogonal spatial axes, namely, the X axis, the Y axis, and the Z axis. In addition, the directions along the X axis, the Y axis, and the Z axis are respectively referred to as the X direction, the Y direction, and the Z direction, and the positive directions along the X axis, the Y axis, and the Z axis toward the + side are respectively referred to as the +X direction, the +Y direction, and the +Z direction, and the negative directions along the X axis, the Y axis, and the Z axis toward the - side are respectively referred to as the -X direction, the -Y direction, and the -Z direction, and the Z direction is referred to as the vertical direction, and the direction toward the upper side along the vertical direction is referred to as the +Z direction, and the direction toward the lower side along the vertical direction is referred to as the -Z direction. The XY plane including the X axis and the Y axis is a horizontal plane. In addition, the AB coordinate system is an orthogonal coordinate system, which is included in the XZ plane including the X axis and the Z axis, and the two spatial axes that intersect with the X axis and the Z axis and are mutually orthogonal are referred to as the A axis and the B axis. In addition, the direction along the A axis is referred to as the A direction, the direction toward the upper side along the A axis is referred to as the +A direction, the opposite direction of the +A direction is referred to as the -A direction, the direction along the B axis is referred to as the B direction, the direction toward the lower side along the B axis is referred to as the +B direction, and the opposite direction of the +B direction is referred to as the -B direction.

[0028] The Y direction is the width direction of the medium P and the depth direction of the device, which intersects the conveying direction of the medium P, and is a horizontal direction. In addition, the Y direction is an example of the depth direction of the device, which intersects both the A direction and the B direction described later. The +Y direction is the direction toward the front of the Y direction, and the -Y direction is the direction toward the back of the Y direction.

[0029] The X direction is the width direction of the device and is horizontal. The +X direction is the direction to the left of the X direction when viewed from the operator of the printer 1 , and the −X direction is the direction to the right of the X direction.

[0030] The Z direction is the device height direction.

[0031] In the printer 1 , the medium P is transported through a transport path T indicated by a dotted line.

[0032] The AB coordinate system shown in the XZ plane is an orthogonal coordinate system. The A direction is an example of the conveying direction of the medium P in the area opposite to the line head 20 described later in the conveying path T. The direction of the A direction toward the upstream is called the -A direction, and the direction toward the downstream is called the +A direction. In the present embodiment, the A direction is a direction inclined in such a manner 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 conveying unit 10 described later. The direction of the line head 20 in the B direction that is closer to the conveying path T is called the +B direction, and the direction away from the conveying path T is called the -B direction. In the present embodiment, the B direction is a direction inclined in such a manner that the +B direction side is located closer to the +Z direction side than the -B direction side, and is orthogonal to the A direction.

[0033] Specifically, if Figure 2 As shown, when viewed from the Y direction, when the angle formed by the B direction and the X direction is taken as the first angle θ1, the first angle θ1 is greater than 0 degrees and equal to or less than 45 degrees, specifically, greater than 10 degrees and equal to or less than 40 degrees, and more specifically, 30 degrees. In addition, when the angle formed by the A direction and the X direction is taken as the third angle θ3, the third angle θ3 is equal to or greater than 45 degrees and less than 90 degrees, specifically, greater than 50 degrees and equal to or less than 80 degrees, and more specifically, 60 degrees. In this way, the moving direction of the line head 20 as the direction of advance and retreat relative to the conveying unit 10 described later is an inclined direction intersecting the horizontal direction and the vertical direction. In addition, the conveying direction of the medium P of the area including the conveying unit 10 recorded by the line head 20 is an inclined direction intersecting the horizontal direction and the vertical direction.

[0034] like Figure 1 As shown, the printer 1 has a housing 2 as an example of a device body. It is assumed that the housing 2 is placed on a horizontal plane. In the +Z direction of the housing 2, which is closer to the center in the Z direction, there is formed a discharge portion 3 that forms a space portion for discharging a medium P on which information is recorded. In addition, in the -Z direction of the housing 2, which is closer to the center in the Z direction, there are provided a plurality of medium boxes 4. The medium box 4 is an example of a medium storage portion. In addition, in the Z direction center of the housing 2, there is provided a manual feed tray 9 that protrudes from the housing 2 in the -X direction. In other words, the manual feed tray 9 is provided on the -X direction side relative to the conveying path T. In the case of recording on a medium P that cannot be provided in the medium box 4, the manual feed tray 9 on which the medium P can be provided is used.

[0035] A plurality of media P are stacked and stored in a plurality of media boxes 4. A pickup roller 6 is provided in the medium box 4 in a manner that is closer to the -X direction than the center thereof so as to be in contact with the upper surface of the medium P. The pickup roller 6 is located below the discharge portion 3. The medium P stored in each medium box 4 is sent out from the medium box 4 toward the conveying path T, which is the -X direction, by the pickup roller 6. The medium P sent out toward the conveying path T by the pickup roller 6 is conveyed along the conveying path T by the conveying roller pair 7 and the conveying roller pair 8. In the conveying path T, there are provided a conveying path T1 for conveying the medium P from an external device and a conveying path T2 that merges with the conveying path T from the -X direction side. The conveying path T2 can convey the medium P set in the manual feed tray 9 to the conveying path T. The position where the manual feed tray 9 merges with the conveying path T is located on the -X direction side relative to the conveying path T2. Thus, it is easy to form the conveying path T2 as a path with less curvature along the manual feed tray 9.

[0036] In addition, the conveying path T is provided with a conveying unit 10 described later, a plurality of conveying roller pairs 11 for conveying the medium P, a registration roller pair 11A for correcting the inclination of the medium P, a discharge roller pair 11B, a plurality of baffles 12 for switching the path of the conveying medium P, and a medium width sensor 13 for detecting the width of the medium P in the Y direction.

[0037] The conveying path T is curved in the area opposite to the medium width sensor 13, and extends from the medium width sensor 13 obliquely upward, that is, in the +A direction. A registration roller pair 11A is provided upstream of the conveying unit 10 in the conveying path T. The registration roller pair 11A is arranged on the -A direction side of the conveying unit 10. The registration roller pair 11A corrects the skew of the conveyed medium P. In addition, the skew of the medium P refers to a state in which the posture of the medium P is inclined relative to the conveying direction.

[0038] In the conveying path T, there are provided a conveying path T3 and a conveying path T4 toward the discharge section 3, and a reversing path T5 for reversing the front and back of the medium P. In the conveying path T3 and the conveying path T4, there are provided a discharge roller pair 11B for discharging the medium P with the ink ejected toward the discharge section 3. 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 with the ink ejected is discharged to the discharge section 3 and stacked.

[0039] In addition, the housing 2 includes an ink storage unit 23 for storing ink, a waste liquid storage unit 16 for storing waste liquid of ink, and a control unit 26 for controlling the operation of each part of the printer 1. The ink storage unit 23 supplies ink to the line head 20 via a tube (not shown). Figure 2As shown, the waste liquid storage section 16 is connected to a first maintenance unit 62 described later via a flexible waste liquid pipe 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 pipe 16A and stores it as waste liquid.

[0040] The control unit 26 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and memory (not shown), and controls the conveyance of the medium P in the printer 1 and the recording of information on the medium P using the line head 20 .

[0041] like Figure 2 As shown, in the discharge section 3, a discharge tray 21 is provided corresponding to the conveying path T3 and the conveying path T4. The discharge tray 21 constituting the bottom of the discharge section 3 is a plate-shaped member as an example of a loading member, and has a loading surface 21A on which the discharged medium P is loaded. In addition, the discharge tray 21 is provided in the conveying path T of the medium P, downstream of the conveying unit 10 described later, and is provided in the +Z direction relative to the line head 20 described later in the Z direction.

[0042] Specifically, the discharge tray 21 extends obliquely in such a manner that the portion on the +X direction side is located closer to the +Z direction than the portion on the -X direction side. In other words, in the conveying direction of the medium P, the downstream end of the discharge tray 21 is located closer to the +Z direction than the upstream end. The loading surface 21A has an upward inclination along the discharge direction of the medium P.

[0043] exist Figure 2 In the embodiment, when viewed from the Y direction, the angle between the tilt direction of the mounting surface 21A and the X direction is referred to as the second angle θ2. The second angle θ2 is represented as the angle between the mounting surface 21A and the virtual plane K along the X direction. In the present embodiment, as an example, the second angle θ2 is smaller than the first angle θ1.

[0044] The printer 1 mainly includes 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.

[0045] like Figure 1 , Figure 2As shown in FIG. 1 , the conveying unit 10 includes two pulleys 14, an endless conveying belt 15 hung on the two pulleys 14, and a motor (not shown) for driving the pulleys 14. The conveying unit 10 is an example of a supporting portion. The supporting surface of the conveying belt 15 supporting the medium P constitutes a part of the conveying path T. Figure 2 As shown, the outer dimension D1 of the conveyor belt 15 hung on the two pulleys 14 in the X direction is smaller than the outer dimension D2 of the support surface of the conveyor belt 15 supporting the medium P in the A direction. In other words, the outer dimension D1 in the horizontal direction of the conveyor belt 15 hung on the two pulleys 14 in the direction orthogonal to the width direction of the conveyor belt 15 is smaller than the outer dimension D2 of the support surface of the conveyor belt 15 supporting the medium P in the A direction. The medium P is sucked onto the support surface of the conveyor belt 15 and conveyed to a position opposite to the line head 20. Therefore, as Figure 2 As shown, a charging roller 17 for charging the transport unit 10 and a destaticizing brush 18 for destaticizing the medium P supported by the transport unit 10 are provided in the housing 2 .

[0046] The charging roller 17 is a part of the 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 so that the medium P is adsorbed on the supporting surface of the conveyor belt 15. The charging roller 17 is set at a position on the +B direction side relative to the endless conveyor belt 15 hung on the two pulleys 14. The charging roller 17 can also be set at a position to clamp the conveyor belt 15 between the pulley 14 located on the -A direction side of the two pulleys 14.

[0047] The charging roller 17 is in contact with the supporting surface of the conveyor belt 15, and is driven to rotate according to the operation of the conveyor belt 15. A power supply device (not shown) for applying a DC voltage to the charging roller 17 is connected to the charging roller 17, whereby the charging roller 17 supplies electric charge to the portion in contact with the conveyor belt 15. The power supply device is controlled by the control unit 26 to turn on and off the voltage applied to the charging roller 17 and to switch the voltage applied to the charging roller 17. In addition, in the present embodiment, the charging roller 17 supplies positive electric charge to the conveyor belt 15, so that the supporting surface of the conveyor belt 15 is charged with positive polarity.

[0048] The de-staticizing brush 18 is an example of a de-staticizing unit. The de-staticizing brush 18 de-staticizes the medium P by contacting the medium P supported by the conveyor belt 15. The de-staticizing brush 18 is disposed at a position on the -B direction side relative to the endless conveyor belt 15 hung on the two pulleys 14. The de-staticizing brush 18 is disposed at a position on the -A direction side relative to the ejection surface NA of the line head 20. The de-staticizing brush 18 may also be disposed at a position where the conveyor belt 15 is sandwiched between the pulley 14 located on the -A direction side of the two pulleys 14.

[0049] The de-staticizing brush 18 removes the charge of the recording surface on the ejection surface NA side of the medium P. Alternatively, the de-staticizing brush 18 may also remove the charge of the support surface of the conveyor belt 15. More specifically, when the support surface of the conveyor belt 15 is charged by the charging roller 17, in the medium P in contact with the support surface, a charge of the opposite polarity is generated on the surface in contact with the support surface, and further, a charge of the opposite polarity to the charge is also generated on the surface on the opposite side of the medium P, that is, the recording surface. The charge on the recording surface side is removed by the de-staticizing brush 18. As a result, only the charge on the side in contact with the conveyor belt 15 remains in the medium P, and as a result, the medium P is adsorbed relative to the support surface.

[0050] The anti-static brush 18 may be made of any material as long as it can remove charges from the medium P and the conveyor belt 15, and may be made of a resin material such as conductive nylon, for example. The anti-static brush 18 is connected to a switching device (not shown), which is controlled by the control unit 26 to switch between a state where the anti-static brush 18 is grounded, i.e., connected to the earth, and a state where it is not grounded.

[0051] 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 in the conveying path T that is opposite to the line head 20. That is, the pulley 14 is driven to rotate, so that the conveying unit 10 conveys the medium P supported by 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. In addition, the conveying unit 10 and the line head 20 are arranged opposite to each other in the B direction. As a method of adsorbing the medium P to the conveyor belt 15, an adsorption method such as an air suction method can also be used.

[0052] The conveying unit 10 may further include a driven roller 19 for suppressing the medium P from floating from the supporting surface of the conveyor belt 15. In this case, the driven roller 19 is provided at a position on the -B direction side relative to the endless conveyor belt 15 hung on the two pulleys 14. The driven roller 19 is provided at a position between the ejection surface NA of the line head 20 and the static removal brush 18 in the A direction. The driven roller 19 is provided at a position where the medium P is clamped between the conveyor belt 15, and is driven to rotate according to the movement of the medium P supported by the conveyor belt 15. In addition, the driven roller 19 may be made of a conductive material such as metal, for example, and be grounded.

[0053] The line head 20 is an example of a head. The line head 20 has nozzles N that eject ink as an example of liquid. The line head 20 is arranged opposite to the conveying unit 10 in the B direction at a recording position described later, and records information by ejecting ink from the nozzles N to the medium P conveyed in the conveying direction. The line head 20 is an inkjet 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 arranged is arranged along the A direction and the Y direction. Figure 2 As shown, the ejection surface NA faces the +B direction. The size of the ejection surface NA in the Y direction of the ejection surface NA is larger than the size of the ejection surface NA in the A direction. The ejection surface NA is located on the +A direction side relative to the center of the support surface of the support medium P in the conveyor belt 15 in the A direction. That is, the line head 20 is located on the +A direction side relative to the center of the support surface of the support medium P in the conveyor belt 15 in the A direction.

[0054] The line head 20 is configured as an inkjet head that can record on the entire width direction of the medium P without moving the medium P in the width direction. However, the type of inkjet head is not limited to this, and may be a type that is mounted on a carriage and ejects ink while moving in the width direction of the medium P.

[0055] like Figure 4 As shown, the line head 20 extends in the Y direction. At the sides of the two ends of the line head 20 in the Y direction, a plate portion 20A protrudes toward the +A direction. In addition, support frames 22 are respectively installed at the two ends of the line head 20 in the Y direction. Figure 4 The second maintenance unit 72 shown will be described later.

[0056] The support frame 22 is formed as a side plate along the AB plane, and extends in the -B direction relative to the line head 20. Columnar support pins 24 extending in the +Y direction and the -Y direction are respectively provided at both ends of the Y-direction outer side surface of the support frame 22. An annular roller 25 is rotatably provided on the support pin 24.

[0057] In addition, 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.

[0058] The rack 28 is a plate-shaped member with the Y direction as the thickness direction and extending in the B direction. A plurality of teeth 28A arranged in the B direction are formed at the end of the rack 28 in the -A direction. In addition, a long hole 28B is formed in the rack 28 that penetrates in the Y direction and is long in the B direction. The support pin 27 is inserted through the long hole 28B. Thus, the rack 28 can be relatively moved in the B direction relative to the support frame 22.

[0059] 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. Thus, the coil spring 29 applies elastic force in the B direction to the rack 28.

[0060] Make the line head 20 Figure 1 The replacement position shown by the two-dot chain line can be disengaged Figure 3The head moving unit 30 is shown. The replacement position is the position farthest from the conveying unit 10 in the -B direction in the moving direction of the line head 20. Specifically, the support frame 22 moved in the -B direction along the guide rail 37 described later is further lifted in the +Z direction along the guide rail 38, so that the line head 20 is separated from the head moving unit 30.

[0061] The head moving unit 30 moves the line head 20 to a recording position and a retreat position described later along the B direction. In other words, the head moving unit 30 moves the line head 20 to the B direction in such a manner that the moving direction of the line head 20 intersects both the vertical direction and the horizontal direction. In addition, the moving direction is an inclined direction intersecting the horizontal plane at an angle greater than 0 degrees and less than 45 degrees. Specifically, the angle at which the moving direction intersects the horizontal plane is 30 degrees.

[0062] like Figure 3 , Figure 5 As shown, the head moving unit 30 includes a main frame 32 constituting a main body portion, a guide member 36 for guiding the line head 20 in the B direction, and a drive unit 40 for driving the line head 20 described later in the B direction. Furthermore, the head moving unit 30 moves the line head 20 to one or more retreat positions described later that are away from the conveying unit 10 relative to the recording position described later. Specifically, the head moving unit 30 is configured to enable the line head 20 to move to a first position, a second position, and a third position. In addition, the first position, the second position, and the third position will be described later.

[0063] The main frame 32 is included in the housing 2. That is, the main frame 32 is included in an example of the device body. Specifically, the main frame 32 includes a side frame 33, a side frame 34, and a plurality of horizontal frames 35.

[0064] The side frame 33 and the side frame 34 are respectively formed as side plates along the AB plane and are arranged opposite to each other at intervals in the Y direction. The side frame 33 is arranged on the +Y direction side, and the side frame 34 is arranged on the -Y direction side. A through hole 34A for movement of the second maintenance unit 72 described later is formed in the side frame 34. A plurality of horizontal frames 35 connect the side frames 33 and the side frames 34 in the Y direction. In addition, the line head 20 is arranged in a space surrounded by the plurality of horizontal frames 35.

[0065] The guide member 36 is an example of a guide portion, and one guide member is provided on each of the side frames 33 and 34. The two guide members 36 are arranged substantially symmetrically with respect to the center in the Y direction of the main frame 32. Therefore, the guide member 36 in the -Y direction will be described, and the description of the guide member 36 in the +Y direction will be omitted.

[0066] like Figure 5As shown in FIG. 1 , the guide member 36 is mounted on the side surface of the side frame 34 in the +Y direction. The guide member 36 includes a guide rail 37 extending in the B direction and a guide rail 38 branching from the middle of the guide rail 37 and extending in the Z direction. The guide rails 37 and 38 are grooves that open in the +Y direction. In addition, the guide rails 37 and 38 guide the roller 25 in the B direction or the Z direction.

[0067] like Figure 5 As shown, the side frame 34 is provided with a guide rail 71 constituting the cover moving portion 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 into a groove shape that opens inward toward the Y direction and extends along the A direction. In addition, the set of guide rails 71 supports a plurality of rollers 73 described later so as to be movable in the A direction. That is, the guide rails 71 guide the plurality of rollers 73 in the A direction, thereby enabling the first maintenance unit 62 described later to move in the A direction.

[0068] like Figure 5 As shown, the drive unit 40 includes a motor 41, a gear unit (not shown), a shaft 42, and a pinion 43, and is driven by the control unit 26. The shaft 42 extends in the Y direction. Both ends of the shaft 42 are supported so that they can Figure 3 The pinion gear 43 is mounted on the side frame 33 and the side frame 34 shown. The pinion gear 43 is mounted on both ends of the shaft 42 in the Y direction. The pinion gear 43 has a tooth portion 43A formed on the outer periphery thereof to mesh with the tooth portion 28A.

[0069] The motor 41 rotates the shaft 42 and the pinion gear 43 in one direction or in the opposite direction via a gear unit (not shown). In this way, the drive unit 40 drives the pinion gear 43 to rotate, thereby moving the line head 20 in the B direction.

[0070] like Figure 6 As shown, the printer 1 includes a maintenance unit 60 , a cover moving portion 80 , a cap unit 90 , and a rotating mechanism portion 100 .

[0071] The maintenance unit 60 is an example of a storage unit that stores the nozzle N and performs maintenance on the nozzle N. Specifically, the maintenance unit 60 includes a first maintenance unit 62 that can cover the nozzle N and a second maintenance unit 72 that cleans the ejection surface NA of the ink in the nozzle N by wiping. The second maintenance unit 72 will be described later.

[0072] The first maintenance unit 62 is an example of a cover. In addition, the first maintenance unit 62 includes a cover body 63, a cover 64 covering the nozzle N, and a flushing portion 66 facing the nozzle N and receiving the ink ejected from the nozzle N. In addition, the first maintenance unit 62 includes the cover 64 and the flushing portion 66 along the A direction, and switches the state where the cover 64 faces the nozzle N and the state where the flushing portion 66 faces the nozzle N by moving in the A direction. Furthermore, the first maintenance unit 62 has a standby position on the -A direction side relative to the line head 20, and has a standby position, an ejection position, and a covering position in sequence toward the +A direction.

[0073] The standby position is away from the covering position in the direction of -A in the direction of A. That is, the standby position is away from the line head 20 relative to the covering position and is located below the covering position. As a result, it is easy to arrange the waste liquid pipe 16A connecting the first maintenance unit 62 and the waste liquid storage part 16 below the line head 20. Therefore, the waste liquid pipe 16A is not easy to interfere with the line head 20 and the conveying path T. In addition, in the covering position, since the waste liquid pipe 16A is not easy to be bent, it is easy to collect the waste liquid from the first maintenance unit 62 in the waste liquid storage part 16.

[0074] The ejection position is the position of the first maintenance unit 62 when the flushing section 66 is opposed to the nozzle N. The ejection position is away from the standby position in the +A direction in the A direction. The covering position is the position of the first maintenance unit 62 when the cover 64 covers the ejection surface NA. The first maintenance unit 62 in the covering position is located between the line head 20 and the conveying unit 10 in the B direction. The covering position is away from the ejection position in the -A direction in the A direction.

[0075] like Figure 7 As shown, the cover body 63 is formed into a box shape in which the dimension in the Y direction is larger than the dimension in the A direction. An opening portion 65 opening in the -B direction is formed on the cover body 63. Racks 69 extending in the A direction are respectively provided on the side walls 63A in the +Y direction and the side walls 63A in the -Y direction of the cover body 63. The rack 69 has a plurality of teeth 69A arranged in the A direction. In addition, a plurality of rollers 73 capable of rotating with the Y direction as the axial direction are provided on the two side walls 63A. A partition wall 67 is provided on the inner side of the cover body 63. The partition wall 67 divides the space in the cover body 63 into a space in the +A direction and a space in the -A direction. A cover 64 is arranged in the space in the -A direction of the partition wall 67, and a flushing portion 66 is arranged in the space in the +A direction of the partition wall 67.

[0076] The cover 64 of the first maintenance unit 62 has a cover surface 64A that covers the ejection surface NA. The cover 64 has a recess 64B that opens to the cover surface 64A. The size and shape of the cover surface 64A are the size and shape that cover the ejection surface NA. Therefore, when the cover surface 64A in the covering position is observed from the -B direction side, the size D3 of the cover surface 64A in the Y direction is larger than the size D4 of the cover surface 64A in the A direction. In addition, when the first maintenance unit 62 in the covering position is observed from the B direction, the size of the first maintenance unit 62 in the Y direction is larger than the size of the first maintenance unit 62 in the A direction. Here, the standby position of the first maintenance unit 62 is set at a position separated from the covering position in the A direction. As a result, compared with the case where the standby position is set at a position separated from the covering position in the Y direction, the interval between the standby position and the covering position can be narrowed, and the loading area of ​​the printer 1 can be easily reduced.

[0077] In addition, the cover 64 covers the ejection surface NA by arranging the cover surface 64A opposite to the ejection surface NA in the B direction. That is, the first maintenance unit 62 covers the ejection surface NA in the covering position, thereby suppressing the nozzle N from drying and suppressing the increase in the viscosity of the ink. In addition, the cover 64 can cover the nozzle N when the line head 20 is in the retreat position. That is, the first maintenance unit 62 does not cover the ejection surface NA in the standby position and the ejection position.

[0078] The flushing section 66 is an example of a receiving section, and is provided in the opening 65. The flushing section 66 is arranged on the +A direction side of the cover 64 in the A direction. In other words, when the first maintenance unit 62 is arranged in the standby position, the flushing section 66 is arranged at a position closer to the line head 20 than the cover 64 in the A direction.

[0079] The flushing section 66 is configured as a flushing box that opens in the -B direction and has porous fibers such as felt. The flushing section 66 captures the ink ejected from the nozzle N. In the nozzle N, when the viscosity of the ink increases, the ink is ejected toward the flushing section 66, so that the viscosity of the ink is maintained within a set range. Thus, poor ejection of the ink from the nozzle N is suppressed.

[0080] The second maintenance unit 72 is an example of a cleaning unit. The second maintenance unit 72 includes a main body 74 and a scraper 76. The main body 74 is formed into a box shape that opens in the -B direction. As an example, the scraper 76 is made of a rectangular plate-shaped rubber. In addition, the scraper 76 protrudes from the main body 74 in the -B direction at a location where the nozzle N is wiped, and is provided on the main body 74 in a state inclined relative to the A direction and the Y direction.

[0081] The second maintenance unit 72 can move forward and backward in the Y direction between a retreat position in the -Y direction relative to the side frame 34 and a cleaning position for cleaning the ejection surface NA by a blade moving portion (not shown). The Y direction is an example of a second direction in which the blade moving portion moves the second maintenance unit 72 forward and backward. The maximum movement amount D12 of the second maintenance unit 72 in the Y direction is Figure 4 The distance in the Y direction between the retreat position shown by the solid line and the position shown by the double-dotted line farthest from the retreat position. The second maintenance unit 72 in the cleaning position is located between the line head 20 and the conveying unit 10 in the B direction. As an example, the driving unit not shown includes a motor and a belt to which the second maintenance unit 72 is mounted, and the belt is moved around by the rotation of the motor, thereby moving the second maintenance unit 72 in the Y direction. In addition, the second maintenance unit 72 retreats to the retreat position when the first maintenance unit 62 covers the line head 20 and the line head 20 is recording.

[0082] The cover moving part 80 moves the first maintenance unit 62 in the direction A between the covering position and the standby position. The direction A is an example of the first direction in which the cover moving part 80 moves the first maintenance unit 62 forward and backward. The first direction is an inclined direction that intersects the horizontal plane at an angle of more than 45 degrees and less than 90 degrees. Specifically, the angle of the first direction intersecting the horizontal plane is 60 degrees. Therefore, the inclination of the first direction is greater than the moving direction. Figure 2 As shown, the cover moving portion 80 moves the first maintenance unit 62 in the -B direction side relative to the static-eliminating brush 18. As a result, the interval between the registration roller pair 11A and the line head 20 in the A direction can be narrowed. Therefore, the medium P with a small skew after passing through the registration roller pair 11A can be recorded using the line head 20. In addition, the cover moving portion 80 moves the first maintenance unit 62 in the A direction on the -B direction side relative to the registration roller pair 11A. The cover moving portion 80 supports the first maintenance unit 62 in a state where the cover surface 64A of the cover 64 is facing the -B direction. The state facing the -B direction is an example of a state facing a direction between the X direction and the +Z direction. Specifically, the cover moving portion 80 includes: a gear 82 having a tooth portion 82A meshing with the tooth portion 69A of the rack 69; a motor 84 that rotates the gear 82; and Figure 6 The guide rail 71 shown supports the roller 73 of the first maintenance unit 62. The driving control of the cover moving unit 80 is performed by the control unit 26.

[0083] When the line head 20 is located at the retracted position described later, the cover moving section 80 moves the first maintenance unit 62 into between the line head 20 at the retracted position and the transport unit 10. In addition, before the line head 20 is located at the recording position described later, the cover moving section 80 moves the first maintenance unit 62 away from between the line head 20 at the retracted position and the transport unit 10 in the -A direction.

[0084] The cap unit 90 is an example of a cap portion. The cap unit 90 is formed as a rectangular parallelepiped shape that is long in the Y direction and can rotate around a rotation axis that extends in the Y direction. The cap unit 90 is located closer to the +A direction side than the line head 20 in the A direction at the ejection position. When the cap 64 covers the nozzle N, the cap unit 90 takes a closed posture covering the flushing portion 66.

[0085] The rotation mechanism 100 rotates the cap unit 90 about the 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 cap unit 90 so that the cap unit 90 is in a closed position.

[0086] Next, Figure 2 The positions of the line head 20 in the B direction when it is moved by the head moving unit 30 and the position of the maintenance unit 60 will be described.

[0087] like Figure 8 As shown, the recording position of the line head 20 refers to the stop position of the line head 20 when the line head 20 can record information on the medium P. When the line head 20 is at the recording position, the first maintenance unit 62 is at the standby position, and the second maintenance unit 72 is at the retracted position.

[0088] The retracted position of the line head 20 is a stop position of the line head 20 when the line head 20 moves away from the transport unit 10 in the -B direction from the recording position. The retracted position of the line head 20 includes a first position, a second position, a third position, a head standby position, and a replacement position described below.

[0089] like Fig. 9 As shown, the first position of the line head 20 refers to the position of the line head 20 when the first maintenance unit 62 covers the nozzle N in the B direction. When the line head 20 is in the first position, the first maintenance unit 62 is in the covering position, and the second maintenance unit 72 is in the retreat position. When viewed from the Z direction, the line head 20 in the first position overlaps at least a portion with the first maintenance unit 62 in the covering position. In addition, when viewed from the Z direction, the first maintenance unit 62 in the covering position overlaps at least a portion with the conveying unit 10.

[0090] like Fig.10 As shown, the second position of the line head 20 refers to the position of the line head 20 when the distance between the flushing section 66 and the nozzle N in the B direction is farther than that in the first position and they are opposite to each other. In addition, in the second position, the flushing section 66 may be separated from the nozzle 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 retreat position.

[0091] like Fig.11 As shown, the third position of the line head 20 refers to the position of the line head 20 when the second maintenance unit 72 can clean the ejection surface NA of the nozzle N in the B direction. 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 can move between the retreat position and the cleaning position in the Y direction.

[0092] like Fig.12 as well as Fig.13 As shown, the head standby position of the line head 20 refers to a position in the B direction where the line head 20 is farther away from the conveying 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 stands by until the movement is completed when the first maintenance unit 62 and the second maintenance unit 72 move. When the line head 20 is in the head standby position, and when the first maintenance unit 62 moves in the A direction, the second maintenance unit 72 is in the retracted position. In addition, when the second maintenance unit 72 moves in the Y direction, the first maintenance unit 62 is in the standby position. In addition, as Fig.12 As shown, the head moving unit 30 is set to move the line head 20 in the B direction from the recording position shown by the double-dotted line ejection surface NA to the head standby position shown by the solid line, and the movement amount D5 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 destaticizing brush 18 in the B direction.

[0093] like Fig.14 As shown, the replacement position of the line head 20 refers to a position in the B direction where the line head 20 is further away from the conveying unit 10 in the -B direction than the head standby position. In other words, the replacement position of the line head 20 is a position farthest from the conveying unit 10 in the B direction. When the line head 20 is detached from the head moving part 30 at the replacement position, the first maintenance unit 62 is in the standby position and the second maintenance unit 72 is in the retreat position. At this time, the first maintenance unit 62 in the standby position is located vertically below the ejection surface NA of the line head 20 in the replacement position. Thus, for example, when the line head 20 is detached, in the case where ink falls from the ejection surface NA, it is possible to prevent the fallen ink from adhering to the conveying path T.

[0094] Thus, as an example, the head moving unit 30 is configured to move the line head 20 to any one of the recording position, the retreat position, the first position, the second position, the third position, the head standby position, and the replacement position. In addition, the head moving unit 30 is configured to place the line head 20 at the head standby position before placing the line head 20 at any one of the first position, the second position, and the third position.

[0095] In addition, if Fig.14As shown, the distance in the B direction between the recording position indicated by the double-dashed line of the ejection surface NA of the line head 20 and the replacement position indicated by the solid line is the maximum movement amount D9 of the line head 20 in the B direction. In addition, the distance in the A direction between the standby position indicated by the solid line of the first maintenance unit 62 and the covering position indicated by the end of the double-dashed line of the rack 69 is the maximum movement amount D8 of the first maintenance unit 62 in the A direction. In the present embodiment, the maximum movement amount D8 of the first maintenance unit 62 in the A direction is equal to or greater than the maximum movement amount D9 of the line head 20 in the B direction.

[0096] in addition, Fig.12 The sum of the outer dimension D10 of the first maintenance unit 62 in the A direction and the maximum movement amount D8 of the first maintenance unit 62 in the A direction is greater than Fig.12 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 is shown. In addition, the maximum movement amount D12 of the second maintenance unit 72 in the Y direction is equal to or greater than the maximum movement amount D8 of the first maintenance unit 62 in the A direction. In addition, the mass of the first maintenance unit 62 is equal to or less than the mass of the line head 20. In addition, the mass of the second maintenance unit 72 is equal to or less than the mass of the first maintenance unit 62.

[0097] As described above, according to the printer 1 of the first embodiment, the following effects can be obtained.

[0098] The printer 1 comprises: a conveying unit 10 having a support surface constituting a conveying path T and conveying a medium P supported on the support surface in a conveying direction; a line head 20 having a discharge surface NA, the discharge surface NA being a discharge surface NA facing the +B direction and provided with a nozzle N for discharging ink to the medium P conveyed in the above-mentioned conveying direction; a first maintenance unit 62 capable of covering the discharge surface NA; a head moving unit 30 for moving the line head 20 in a moving direction; and a cover moving unit 80 for supporting the first maintenance unit 62 and moving the first maintenance unit 62. The cover moving unit 80 moves between a covering position where the cover surface 64A of the first maintenance unit 62 covers the ejection surface NA and a standby position where the cover surface 64A does not cover the ejection surface NA. When the cover surface 64A in the covering position is viewed from the B direction, a dimension D3 of the cover surface 64A in the Y direction is larger than a dimension D4 of the cover surface 64A in the A direction. The standby position is away from the covering position in the conveying direction. The cover moving unit 80 supports the first maintenance unit 62 in a state where the cover surface 64A faces an inclined direction between the X direction and the +Z direction. Thus, since the cover surface 64A faces an inclined direction between the X direction and the +Z direction, the horizontal dimension of the cover surface 64A can be reduced compared to a case where the cover surface 64A faces vertically upward. Therefore, the installation area of ​​the printer 1 can be reduced.

[0099] The conveying direction is the A direction, the moving direction is the B direction, and the cover moving part 80 supports the first maintenance unit 62 and moves it in the A direction in a state where the cover surface 64A faces the -B direction. Thus, in a state where the cover surface 64A faces the -B direction, since the first maintenance unit 62 moves in the A direction, the ejection surface NA is always kept facing the +B direction and the first maintenance unit 62 can cover the ejection surface NA. Therefore, it is easy to stabilize the meniscus formed in the nozzle N.

[0100] The printer 1 further includes a charging roller 17 for charging the support surface of the transport unit 10, and a de-staticizing brush 18 that is arranged on the -B direction side relative to the transport unit 10 and de-staticizes the medium P supported by the transport unit 10, and the cover moving unit 80 moves the first maintenance unit 62 on the -B direction side relative to the de-staticizing brush 18. Thus, since the first maintenance unit 62 is moved on the -B direction side relative to the de-staticizing brush 18, it is not necessary to move the de-staticizing brush 18 in order to avoid interference between the de-staticizing brush 18 and the first maintenance unit 62.

[0101] The head moving unit 30 moves the line head 20 in the B direction by a larger amount than the sum of the size of the first maintenance unit 62 in the B direction and the size of the static removing brush 18 in the B direction. Thus, the discharge surface NA can be covered by the cover surface 64A according to the movement of the line head 20 in the B direction and the movement of the first maintenance unit 62 in the A direction.

[0102] The first maintenance unit 62 is connected to the waste liquid storage unit 16 capable of storing waste liquid via the waste liquid pipe 16A, and the standby position is located below the covering position, and the waste liquid storage unit 16 is located below the first maintenance unit 62. Thus, the waste liquid from the first maintenance unit 62 can be easily collected in the waste liquid storage unit 16.

[0103] The transport unit 10 transports the medium P in the +A direction, and further includes a registration roller pair 11A disposed on the -A direction side relative to the transport unit 10, and the cover moving unit 80 moves the first maintenance unit 62 on the -B direction side relative to the registration roller pair 11A in the A direction. As a result, the interval between the registration roller pair 11A and the line head 20 in the A direction can be narrowed. Therefore, the line head 20 can record on the medium P with a small skew after passing through the registration roller pair 11A.

[0104] The printer 1 further includes: a pickup roller 6 for feeding the medium P stored in the medium box 4 from the medium box 4 in the -X direction; and a discharge roller 11B for discharging the medium P in the +X direction toward the discharge unit 3 on which the medium P with ink ejected is stacked. Thus, it is easy to concentrate the conveying path of the medium P from the medium box 4 to the discharge unit 3 on the -X direction side of the housing 2. Therefore, it is easy to arrange the line head 20 and the first maintenance unit 62 on the +X direction side of the housing 2, and it is easy to miniaturize the printer 1.

[0105] The printer 1 further includes: a manual feed tray 9 provided on the -X direction side with respect to a conveying path T for conveying the medium P fed to the pickup roller 6 toward the discharge unit 3 via the conveying unit 10; and a conveying path T2 which merges with the conveying path T from the -X direction side and can convey the medium P set in the manual feed tray 9 toward the conveying path T. Thus, it is easy to concentrate the conveying path to the discharge unit 3 including the conveying of the medium P from the manual feed tray 9 on the -X direction side of the housing 2. Therefore, it is easy to miniaturize the printer 1.

[0106] 2. Implementation Method 2

[0107] Next, a printer 501 according to Embodiment 2 as an example of a recording device of the present invention is described. The same reference numerals are used for the parts common to the printer 1 according to Embodiment 1, and the description thereof is omitted. The same functions and effects as those of Embodiment 1 are also omitted.

[0108] like Fig.15 As shown, the printer 501 replaces the maintenance unit 60 and the cover moving unit 80 in the first embodiment with a maintenance unit 560 and a cover moving unit 580 .

[0109] 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 cover body 63 of the first maintenance unit 62 in the first embodiment with a cover body 563, and removing the flushing unit 66 from the first maintenance unit 62. Therefore, the printer 501 does not include the cover unit 90 and the rotating mechanism unit 100 in the first embodiment.

[0110] The cover body 563 replaces the rack 69 of the cover body 63 in the first embodiment with a rack 569. Therefore, a plurality of teeth 69A (not shown) on the rack 569 are arranged in an arc shape. Fig.15 At the capping position indicated by the two-dot chain line, the cap 64 catches the ink ejected from the nozzle N. Therefore, the ejection position of the first maintenance unit 562 is the same as the capping position.

[0111] The cover moving unit 580 is obtained by replacing the guide rail 71 of the cover moving unit 80 in the first embodiment with a guide rail 571. Fig.15 As shown, the guide rail 571 supports the rollers 73 of the first maintenance unit 562 so that they can move. The guide rail 571 is in an arc shape. Therefore, the guide rail 571 guides the plurality of rollers 73, so that the first maintenance unit 562 can move with the same Fig.15 The device rotates around a rotation axis SC parallel to the Y axis shown.

[0112] Therefore, in the standby position, the direction in which the mask surface 64A in the first maintenance unit 562 faces is an inclined direction between the X direction and the +Z direction, but is different from the -B direction. Fig.15 In the case of the fourth angle θ4 shown, the fourth angle θ4 is greater than the first angle θ1 formed by the B direction and the X direction. In addition, the angle formed by the direction facing the cover surface 64A in the first maintenance unit 562 and the X direction changes from the fourth angle θ4 to the first angle θ1 during the movement from the standby position to the covering position.

[0113] As described above, the printer 501 of the second embodiment includes: a conveying unit 10, which has a conveying path T and conveys the medium P in the conveying direction between the X direction and the A direction; a line head 20, which has a discharge surface NA, which is a discharge surface NA facing the +B direction and is provided with a nozzle N for discharging ink to the medium P conveyed in the above-mentioned conveying direction; a first maintenance unit 562, which can cover the discharge surface NA; a head moving unit 30, which moves the line head 20 in the moving direction; and a cover moving unit 580, which supports the first maintenance unit 562 and The first maintenance unit 562 is moved between a covering position in which the cover surface 64A of the first maintenance unit 562 covers the ejection surface NA and a standby position in which the cover surface 64A does not cover the ejection surface NA, when the cover surface 64A in the covering position is observed from the B direction, a dimension D3 of the cover surface 64A in the Y direction is larger than a dimension D4 of the cover surface 64A in the A direction, the standby position is separated from the covering position in the conveying direction, and the cover moving part 580 supports the first maintenance unit 562 when the cover surface 64A is in a state of being inclined in a direction between the X direction and the +Z direction.

[0114] The printer 1 of the first embodiment and the printer 501 of the second embodiment of the present invention are based on the above-described configuration, but of course, some configurations can be changed or omitted without departing from the gist of the present invention. In addition, the above-described embodiment and other embodiments described below can be combined and implemented with each other within the scope of technical non-contradiction. Other embodiments are described below.

[0115] The first angle θ1 may be equal to the second angle θ2, or may be smaller than the second angle θ2.

[0116] The printer 1 may not include the second maintenance unit 72. In addition, the printer 1 may not include the cover unit 90.

[0117] The printer 1 can also attach and detach the line head 20 in the Y direction.

[0118] In the printer 1 , the flushing section 66 of the first maintenance unit 62 may be arranged on the −A direction side of the A direction relative to the cover 64 .

[0119] The head moving unit 30 may not place the line head 20 at the standby position before placing the line head 20 at any one of the first position, the second position, and the third position.

[0120] In the printer 1, the direction of the cover surface 64A may be changed while the first maintenance unit 62 moves in the direction A. In this case, the cover moving unit 80 may support the first maintenance unit 62 and move it in the direction A while the cover surface 64A faces an inclined direction between the X direction and the +Z direction.

[0121] In the printer 1, the first direction may not be orthogonal to the moving direction. For example, when the moving direction is the B direction and the first angle θ1 formed between the B direction and the X direction is 30 degrees, the angle formed between the first direction and the X direction may be 70 degrees. In addition, in this case, the conveying direction may be the A direction or may not be the A direction. When the conveying direction is not the A direction, the conveying direction may be along the first direction and the angle formed between the conveying direction and the X direction may be 70 degrees.

[0122] In the printer 1, the first maintenance unit 62 may also move on an arc. In this case, the cover moving unit 80 may also support the first maintenance unit 62 via a link mechanism. In addition, the cover moving unit 80 may drive the link mechanism, so that the rack 69 is not provided on the cover body 63 when the first maintenance unit 62 is moved.

[0123] In the printer 1, the conveying direction may not be orthogonal to the +B direction in which the ejection surface NA faces. For example, the conveying direction of the medium P in the area where the line head 20 and the conveying unit 10 face each other may be the X direction. In this case, the cover moving part 80 may support the first maintenance unit 62 and move it in the X direction in a state in which the cover surface 64A faces an inclined direction between the X direction and the +Z direction.
