DETAILED DESCRIPTION

[0025] Hereinafter, the present invention will be briefly described.

[0026] The recording device according to the first aspect is characterized in that it includes: a recording unit that records on a medium by ejecting liquid from a discharge unit; a support unit that is arranged opposite to the recording unit and supports the medium; a moving mechanism unit that moves the recording unit to a recording position and a retreat position in which recording on the medium is possible along a moving direction that is a direction in which the recording unit advances and retreats relative to the support unit, the retreat position being farther from the support unit than the recording position; a cover unit that is movable in a first direction intersecting the moving direction relative to the recording unit and the support unit, the cover unit covering the discharge unit when the recording unit is in the retreat position; and a cleaning unit that is movable in a second direction intersecting both the moving direction and the first direction relative to the recording unit and the support unit, the cleaning unit cleaning the discharge unit when the recording unit is in the retreat position, at least a portion of a first moving area where the cover unit moves and at least a portion of a second moving area where the cleaning unit moves are arranged at the same position in the moving direction.

[0027] According to this aspect, at least a portion of the first movement area where the cover moves and at least a portion of the second movement area where the cleaning unit moves are arranged at the same position in the movement direction. Thus, compared to a configuration in which the first movement area and the second movement area are staggered in the movement direction, the area required for movement of the cover and the cleaning unit is reduced, thereby preventing the recording device from becoming larger in the direction of movement of the recording unit.

[0028] The recording device involved in the second aspect is characterized in that, in the first aspect, a group of side walls opposite to the second direction are provided, the recording unit moves between one of the side walls and the other side wall in the moving direction, and the second moving area penetrates one of the side walls in the second direction.

[0029] According to this aspect, the recording unit moves between the one side wall and the other side wall. Here, since the second movable area penetrates the one side wall in the second direction, the cleaning unit can be retracted outward relative to the one side wall, thereby preventing the movable area of the recording unit from being narrowed by the cleaning unit.

[0030] The recording device according to claim 3 is characterized in that, in the second aspect, a guide member for guiding the recording unit in the moving direction is provided on each of a set of the side walls, and one of the guide members is divided by the second moving area in the moving direction.

[0031] According to this aspect, since the second movement area is located at a position dividing one of the guide members, the guide member for guiding the recording unit and the cleaning unit can be arranged close to each other, thereby enabling the recording device to be miniaturized.

[0032] The recording device according to claim 4 is characterized in that, in the third aspect, the recording portion is provided with a protrusion protruding in the second direction, and the guide member has a longitudinal groove opening toward the recording portion and guiding the protrusion in the moving direction.

[0033] According to this aspect, the longitudinal groove surrounds the protrusion except for the opening portion. Therefore, when the moving mechanism moves the recording unit in the moving direction, the position of the recording unit can be prevented from shifting in the first direction or the second direction.

[0034] The recording device involved in the fifth aspect is characterized in that, in the fourth aspect, two or more protrusions are respectively arranged on one side and the other side of the second direction, and the protrusions have multiple rotating parts that rotate by contact with the longitudinal groove part. When one of the rotating parts is located in the second moving area, the other rotating parts are guided by the longitudinal groove part.

[0035] According to this aspect, when one of the rotating members is located in the space of the second movement area, the other rotating members are guided by the longitudinal grooves. This maintains the supported state of the recording unit regardless of the position of the second movement area, thereby preventing the recording unit from changing its posture during movement.

[0036] The recording device according to claim 6 is characterized in that, in the fourth or fifth aspect, a widened portion widened in the first direction is formed in a portion of the longitudinal groove of the guide member divided by the second movement area.

[0037] According to this aspect, during movement of the recording unit, at least one of the three or more rotating members is positioned in the widened portion. This prevents all of the rotating members from being simultaneously positioned in the narrowest portion of the longitudinal groove, reduces the load acting on the longitudinal groove from the rotating members, and thus prevents wear of a portion of the longitudinal groove due to movement of the rotating members.

[0038] The recording device involved in the seventh aspect is characterized in that, in any one of the fourth to sixth aspects, a transverse groove portion is provided on the one side wall and the other side wall, and the transverse groove portion intersects with the longitudinal groove portion and guides the cover portion in the first direction.

[0039] According to this aspect, since the longitudinal groove portion intersects the lateral groove portion, the recording portion and the cover portion can be arranged close to each other, and thus the recording device can be miniaturized.

[0040] The recording device according to the eighth aspect is characterized in that, in the seventh aspect, the depth of the longitudinal groove portion is deeper than the depth of the transverse groove portion, and the longitudinal groove portion is continuous in the moving direction at the intersection where the longitudinal groove portion and the transverse groove portion intersect.

[0041] According to this aspect, since the depth of the longitudinal groove is deeper than the depth of the lateral groove, the longitudinal groove is continuously arranged in the movement direction at the intersection, thereby preventing the rotating member from coming off the longitudinal groove.

[0042] The recording device involved in the ninth aspect is characterized in that, in the eighth aspect, a plurality of lateral protrusions are provided on the cover portion, each of which protrudes two or more toward one side and the other side of the second direction and is guided by the lateral groove portion, and when one of the lateral protrusions is located at the intersection portion, the other lateral protrusions are guided by the lateral groove portion.

[0043] According to this aspect, when one of the lateral protrusions is located in the space of the intersection, the other lateral protrusions are guided by the lateral groove. This maintains the supported state of the cover regardless of the position of the intersection, thereby preventing the cover from changing its posture during movement.

[0044] The recording device according to claim 10 is characterized in that, in any one of claims 7 to 9, the lateral groove portion and the second movement area are arranged adjacent to each other in the movement direction.

[0045] According to this aspect, since the lateral groove portion and the second movement region are arranged adjacent to each other in the movement direction, the cover portion and the recording portion can be arranged close to each other, and the recording device can be miniaturized in the movement direction.

[0046] The recording device according to claim 11 is characterized in that, in any one of claims 1 to 10, the moving mechanism moves the recording unit so that the moving direction intersects both the vertical direction and the horizontal direction.

[0047] According to this aspect, the moving mechanism moves the recording unit in the moving direction that intersects both the vertical and horizontal directions. The gravity acting on the recording unit in the vertical direction is decomposed into a force component along the moving direction and a force component along a direction orthogonal to the moving direction. The force component acting on the recording unit in the moving direction is smaller than the gravity acting on the recording unit in the vertical direction, thereby reducing the force required to move the recording unit. This reduces the load on the moving mechanism compared to a configuration in which the recording unit is moved in the vertical direction.

[0048] Hereinafter, a printer 1 according to an embodiment of the present invention will be described in detail as an example of a recording device.

[0049] exist Figure 1 1 shows a printer 1 as an example of a recording device. The printer 1 is an inkjet device that performs recording by ejecting ink, an example of a liquid, onto a medium P, typically recording paper. The XYZ coordinate system shown in each figure is an orthogonal coordinate system.

[0050] The Y direction is the width of the medium P and the depth of the device, intersecting the conveyance direction of the medium P. As an example, it is the horizontal direction. Furthermore, the Y direction is an example of the depth of the device, intersecting both the A and B directions described later. The forward direction of the Y direction is referred to as the +Y direction, and the inward direction is referred to as the -Y direction. Furthermore, the Y direction is an example of a second direction.

[0051] The X direction is the width direction of the device, and is horizontal as an example. The leftward direction of the X direction, as viewed from the operator of the printer 1 , is referred to as the +X direction, and the rightward direction is referred to as the −X direction.

[0052] The Z direction is the height direction of the device, and is, for example, the vertical direction. The upward direction of the Z direction is referred to as the +Z direction, and the downward direction is referred to as the -Z direction.

[0053] In the printer 1 , the medium P is conveyed through a conveyance path T indicated by a dotted line.

[0054] The AB coordinate system shown in the XZ plane is an orthogonal coordinate system.

[0055] Direction A is the conveyance direction of the medium P in the area of the conveyance path T that faces the line head 40 (described later). The upstream portion of Direction A is referred to as the -A direction, and the downstream portion is referred to as the +A direction. Direction A is an example of a first direction. In this embodiment, Direction A is defined as being inclined further from the -A direction, such that it is located in the +Z direction. Specifically, Direction A is inclined within a range of 50° to 70° relative to the horizontal, more specifically, approximately 60°.

[0056] The B direction is an example of a moving direction and is the direction in which the line head 40, described later, moves forward and backward relative to the transport unit 10, described later. The direction in which the line head 40 approaches the transport path T in the B direction is referred to as the +B direction, and the direction in which the line head 40 moves away from the transport path T is referred to as the -B direction. In this embodiment, the -B direction is set to be a direction that is tilted further than the +B direction, located in the +Z direction, and is perpendicular to the A direction.

[0057] The printer 1 includes a housing 2 as an example of a main body. A discharge section 3 is formed in the +Z direction at the center of the housing 2 . This discharge section 3 forms a space for discharging information-recorded media P. Furthermore, the housing 2 is provided with a plurality of media cassettes 4 .

[0058] A plurality of media cassettes 4 contain media P. The media P contained in each media cassette 4 is conveyed along a conveyance path T by a pickup roller 6 and a pair of conveyance rollers 7 and 8. A conveyance path T1, which conveys the media P from an external device, merges with a conveyance path T2, which conveys the media P from a manual feed tray 9 provided in the housing 2.

[0059] The transport path T includes a transport unit 10 (described later), a plurality of transport roller pairs 11 for transporting the medium P, a plurality of flappers 12 for switching the path of the medium P, and a medium width sensor 13 for detecting the width of the medium P in the Y direction.

[0060] The conveyance path T curves in an area opposite the media width sensor 13 and extends diagonally upward from the media width sensor 13, i.e., in the +A direction. Downstream of the conveyance unit 10 in the conveyance path T, there are conveyance paths T3 and T4 leading to the discharge section 3, as well as a reversing path T5 for reversing the front and back of the medium P. The discharge section 3 is provided with an ejection tray (not shown) corresponding to the conveyance path T4.

[0061] A discharge tray 21 is provided at the bottom of the discharge section 3. The discharge tray 21 has a placement surface 21A on which the medium P discharged from the transport path T3 is placed.

[0062] Furthermore, the housing 2 includes an ink container 23 for storing ink, a waste liquid storage section 16 for storing waste liquid from the ink, and a control section 26 for controlling the operation of each component of the printer 1. The ink container 23 supplies ink to the line head 40 via a tube (not shown). The waste liquid storage section 16 stores waste liquid that is used for maintenance from the line head 40 to the flushing section 66 (see FIG. 1 ). Figure 2 )Ink of the waste liquid ejected.

[0063] 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, the recording of information on the medium P by the line head 40, etc.

[0064] like Figure 2 and Figure 4 As shown, in the housing 2 of the printer 1 (refer to Figure 1 ), a lateral frame 32 and a lateral frame 34 are provided inside as an example of a set of side walls.

[0065] like Figure 3 As shown, the side frame 32 is composed of a metal plate as an example, and is arranged along the AB plane and the XZ plane (see Figure 1 ) is upright. The lateral frame 32 is an example of a side wall disposed in the -Y direction. A through hole 33 is formed in the lateral frame 32, extending in the Y direction. The size and shape of the through hole 33 are such that the wiper unit 74, described later, can pass through it in the Y direction.

[0066] like Figure 4 As shown, the side frame 34 is composed of a metal plate as an example, and is arranged along the AB plane and the XZ plane (see Figure 1 ) is upright. In addition, the lateral frame 34 is an example of another side wall arranged in the Y direction. The through hole 33 ( Figure 3 ). The lateral frame 34 and the lateral frame 32 (refer to Figure 3 ) are arranged opposite to each other with a gap in the Y direction. The side frame 32 and the side frame 34 are connected by the transverse frames 35A, 35B, and 35C (see Figure 2 A line head 40 is disposed in the space between the lateral frame 32 and the lateral frame 34.

[0067] like Figure 1 As shown, the printer 1 includes a line head 40 for recording on a medium, a transport unit 10 for transporting the medium P while supporting it, and a head moving unit 50 (see FIG. 1 ) for moving the line head 40 in a direction B. Figure 5 ) and a maintenance unit 60 for maintaining the line head 40 as main parts.

[0068] The conveyor unit 10 is an example of a support unit and includes two pulleys 14, an endless conveyor belt 15 wound around the pulleys 14, and a motor (not shown) that drives the pulleys 14. The medium P is conveyed in direction A at a position opposite the line head 40 while being attracted to the surface of the conveyor belt 15. Known adsorption methods such as air suction and electrostatic adsorption can be used to attract the medium P to the conveyor belt 15. In this way, the conveyor belt 15 supports the medium P while attracting it. The conveyor unit 10 and the line head 40 are arranged opposite each other in direction B.

[0069] The line head 40 is an example of a recording unit. Furthermore, the line head 40 includes nozzles N that eject ink, an example of a liquid. The nozzles N are an example of an ejection unit. Furthermore, the line head 40 is arranged opposite the transport unit 10 in the direction B at a recording position (described later). The line head 40 records information on the medium P by ejecting ink from the nozzles N.

[0070] The line head 40 is an ink ejection head configured so that the nozzles N ejecting ink cover the entire area in the Y direction, which is the width direction of the medium P. The nozzle surface on which the nozzles N are arranged extends along the A and Y directions. Furthermore, the line head 40 is configured to record across the entire width of the medium P without moving across the width of the medium P. However, the type of ink ejection head is not limited to this; a type that ejects ink while being mounted on a carriage and moving across the width of the medium P may also be used.

[0071] like Figure 2 As shown, the line head 40 extends in the Y direction. Support frames 42 are attached to both ends of the line head 40 in the Y direction. The support frames 42 are configured as side plates along the AB plane and extend in the -B direction relative to the line head 40.

[0072] The line head 40 and the support frame 42 are arranged between the side frame 32 and the side frame 34 (see Figure 4 That is, the line head 40 is provided to be movable in the B direction between the lateral frame 32 and the lateral frame 34.

[0073] like Figure 3 As shown, the support frame 42 in the -Y direction is provided with a protrusion 44 that protrudes outward in the -Y direction. The protrusion 44 includes rollers 45A and 45B, which are examples of rotating components rotatably mounted on the support frame 42. The rollers 45A and 45B are arranged at intervals in the B direction and aligned in the B direction. The roller 45A is located at the +B end of the support frame 42. The roller 45B is located at the -B end of the support frame 42.

[0074] like Figure 4 As shown, the support frame 42 in the +Y direction is provided with a protrusion 44 that protrudes outward in the +Y direction. The protrusion 44 includes rollers 45C and 45D, which are examples of rotating components rotatably mounted on the support frame 42. The rollers 45C and 45D are arranged at intervals in the B direction and aligned in the B direction. The roller 45C is located at the +B end of the support frame 42. The roller 45D is located at the -B end of the support frame 42.

[0075] Roller 45A, Roller 45B (refer to Figure 3 ) and roller 45C, roller 45D are taken as an example and are set to the same structure. Although the figure is omitted, when the rollers 45A, 45B, 45C, and 45D are not distinguished, they are referred to as multiple rollers 45. The multiple rollers 45 are connected to the guide rail 93 (see Figure 3 ) and the guide rail 104 and rotates, and is guided in the B direction. In addition, three or more rollers 45 may be respectively arranged on one side or the other side of the Y direction.

[0076] The roller 45A is an example of a rotating member. The rollers 45B, 45C, and 45D are examples of other rotating members. For example, the roller 45A is located in the second movement area S2 (see FIG. Figure 8 ), the configuration of the rollers 45A, 45B, 45C, 45D is predetermined in such a manner that the rollers 45B, 45C, 45D are guided by the guide rails 93 and 104 described later.

[0077] The length corresponding to the interval between the rollers 45A and 45B in the B direction and the length corresponding to the interval between the rollers 45C and 45D in the B direction are both longer than the length corresponding to the width of the through hole 33 in the B direction.

[0078] like Figure 5 As shown, a bracket 46 is provided on the support frame 42. The bracket 46 is a plate-shaped member with the Y direction as the thickness direction, and extends in the B direction. A plurality of teeth 46A arranged in the B direction are formed at the end of the bracket 46 in the -A direction.

[0079] The head moving unit 50 is an example of a moving mechanism. Furthermore, the head moving unit 50 moves the line head 40 to a recording position and a retracted position, described later, along the B direction, which is the direction in which the line head 40 advances and retreats relative to the transport unit 10. In other words, the head moving unit 50 moves the line head 40 in the B direction so that the moving direction intersects both the vertical and horizontal directions.

[0080] The head moving unit 50 includes, for example, a driving unit 52 for driving the line head 40 in the B direction and an adjusting unit 56 for adjusting the position of the line head 40 in the B direction (see FIG. Figure 4 ) and is constituted. Furthermore, the head moving unit 50 moves the line head 40 away from the transport unit 10 relative to the recording position (refer to Figure 1 The recording position and the retracted position of the line head 40 will be described later.

[0081] The drive unit 52 is composed of a motor 53 and a pinion 54, and is controlled by the control unit 26 (see Figure 1 ) controls the drive. The pinion 54 has a plurality of teeth 54A. The plurality of teeth 54A mesh with the plurality of teeth 46A.

[0082] The motor 53 rotates the pinion 54 in one direction or in the reverse direction. Thus, the driving unit 52 drives the pinion 54 by rotating it, thereby moving the line head 40 in the B direction.

[0083] like Figure 6 As shown, the adjustment unit 56 is provided on the side frame 32. In addition, the adjustment unit 56 is, for example, composed of an eccentric cam and a main shaft 59 (see Figure 4 ) of the motor 57 and the automatic adjustment portion 56A provided on the side frame 34 (see Figure 4 ) of the manual adjustment portion 56B (see Figure 4 ) In the automatic adjustment section 56A, an eccentric cam (not shown) contacts a portion of the line head 40, thereby adjusting the recording position of the line head 40. In the manual adjustment section 56B, the inclination of the line head 40 is adjusted by rotating an adjustment screw (not shown) that adjusts the position of the main shaft 59.

[0084] like Figure 2 As shown, the maintenance unit 60 includes a cap unit 62 as an example of a cap portion and a wiper unit 74 as an example of a cleaning portion. The cap unit 62 functions as a first maintenance unit for covering the nozzle N. The wiper unit 74 functions as a second maintenance unit for cleaning the ejection surface of the nozzle N.

[0085] The cover unit 62 is provided so as to be movable by a drive unit 70 (see Figure 5 ) and moves in the direction A. Specifically, the cap unit 62 includes a unit body 63, a cap portion 64 that covers the nozzles N, and a flushing portion 66 that covers the nozzles N and receives ink ejected from the nozzles N.

[0086] The cap unit 62 includes a cap portion 64 and a flushing portion 66 along the A direction, and switches between a state where the cap portion 64 faces the nozzle N and a state where the flushing portion 66 faces the nozzle N by moving in the A direction.

[0087] The cap unit 62 has a standby position upstream of the line head 40 in direction A, and has a standby position, a discharge position, and a covering position in order from upstream to downstream in direction A. The discharge position is the position of the cap unit 62 when the flushing section 66 faces the nozzle N. The covering position is the position of the cap unit 62 when the cover plate section 64 covers the nozzle N.

[0088] The unit body 63 is formed into a box shape that is long in the Y direction and short in the A direction. The unit body 63 has an opening 68 that opens in the -B direction. The unit body 63 also has a side plate 63A located in the -Y direction (see Figure 3 ) and the side plate 63B located in the +Y direction (refer to Figure 4 ). The side plate 63A and the side plate 63B are opposed to each other in the Y direction.

[0089] A partition plate 67 is provided inside the unit body 63. The partition plate 67 divides the space inside the unit body 63 into a space in the +A direction and a space in the -A direction. The cover plate 64 is disposed in the -A direction space of the partition plate 67, and the flushing section 66 is disposed in the +A direction space of the partition plate 67.

[0090] The size and shape of the cover portion 64 are designed to cover the ejection surface NA of the nozzles N. Furthermore, the cover portion 64 is positioned opposite the ejection surface NA in the direction B, thereby covering the ejection surface NA. Covering the ejection surface NA with the cover portion 64 prevents drying of the nozzles N and increases in ink viscosity. Furthermore, the cover portion 64 is designed to cover the nozzles N when the line head 40 is in the retracted position, described below.

[0091] The flushing section 66 is an example of a receiving section and is provided within the opening 68. Furthermore, the flushing section 66 is positioned downstream of the cover section 64 in the A direction. In other words, when the cover unit 62 is in the standby position, the flushing section 66 is positioned closer to the line head 40 in the A direction than the cover section 64. Furthermore, the flushing section 66 is configured as a flushing box that opens in the -B direction and includes porous fibers such as felt. Furthermore, the flushing section 66 receives ink ejected from the nozzle N. In the nozzle N, if the viscosity of the ink increases, the ink is ejected toward the flushing section 66, thereby maintaining the viscosity of the ink within a set range. This suppresses defective ink ejection from the nozzle N.

[0092] like Figure 5 As shown in FIG. 1 , a bracket 65 extending in the A direction is formed on the unit body 63 . The bracket 65 has a plurality of teeth 65A arranged in the A direction.

[0093] like Figure 3As shown, rollers 69A, 69B, and 69C are rotatably mounted on side plate 63A in the -Y direction, with the Y direction as their axial direction. Rollers 69A, 69B, and 69C protrude from side plate 63A in the -Y direction. Rollers 69A, 69B, and 69C have the same structure, differing only in their placement. Furthermore, rollers 69A, 69B, and 69C are arranged sequentially from downstream to upstream in the A direction. As an example, the spacing between rollers 69A and 69B is narrower than the spacing between rollers 69B and 69C.

[0094] like Figure 4 As shown, the rollers 69D, 69E, and 69F are rotatably provided on the side plate 63B in the +Y direction with the Y direction as the axial direction. The rollers 69D, 69E, and 69F protrude from the side plate 63B in the +Y direction. The rollers 69D, 69E, and 69F are arranged in the same manner as the rollers 69A, 69B, and 69C (see FIG. Figure 3 ) have the same structure, differing only in their arrangement. Furthermore, rollers 69D, 69E, and 69F are arranged sequentially from downstream to upstream in the A direction. As an example, the spacing between rollers 69D and 69E is narrower than the spacing between rollers 69E and 69F. As an example, the positions of rollers 69D and 69E in the A direction differ from the positions of rollers 69A and 69B in the A direction.

[0095] Although not shown in the figure, rollers 69A, 69B, 69C, 69D, 69E, and 69F are referred to as rollers 69 unless otherwise specified. Rollers 69 are an example of lateral protrusions. Rollers 69 rotate by contact with guide rails 98 and 106 (described later) and are guided in the A direction. Alternatively, three or more rollers 69 may be arranged on one side and three on the other side in the Y direction.

[0096] In addition, roller 69A is an example of a lateral protrusion. Rollers 69B, 69C, 69D, 69E, and 69F are examples of other lateral protrusions. As an example, roller 69A is located at the intersection 99 (see Figure 3 ) when rollers 69A, 69B, 69C, 69D, 69E, 69F are pre-determined in such a way that rollers 69B, 69C, 69D, 69E, 69F are guided by guide rails 98 and 106 described later.

[0097] like Figure 5 As shown, the drive unit 70 includes a pinion 72 and a motor (not shown) for rotating the pinion 72. The drive unit 70 is controlled by the control unit 26 (see Figure 1 ) is performed. The pinion 72 has a plurality of teeth 72A. The plurality of teeth 72A mesh with the plurality of teeth 65A.

[0098] When the line head 40 is located at a retracted position described later, the driving unit 70 moves the cover unit 62 into the gap between the line head 40 and the transport unit 10 (see FIG. Figure 1 ). In addition, the drive unit 70 retracts the cap unit 62 from between the line head 40 and the transport unit 10 in the −A direction before the line head 40 is located at a recording position described later.

[0099] Thus, the cap unit 62 is provided to be able to advance and retreat in the direction A intersecting the direction B between the line head 40 and the transport unit 10 , and is configured to cover the nozzles N when the line head 40 is located at a retracted position described later.

[0100] like Figure 6 As shown, the wiper unit 74 includes a main body 75 and a scraper 76 as an example of a cleaning member. In addition, the wiper unit 74 is configured to be able to pass through the through hole 33. The main body 75 is formed into a box shape that opens in the -B direction. The scraper 76 is, for example, made of a rectangular plate of rubber. In addition, the wiping nozzle N of the scraper 76 (see Figure 1 ) portion protrudes from the main body 75 in the -B direction and is provided on the main body 75 in a state inclined relative to the A direction and the Y direction.

[0101] The wiper unit 74 can be advanced, extended, and retracted in the Y direction by the drive unit 80. The position where the wiper unit 74 stops in the -Y direction relative to the lateral frame 32 is referred to as the retracted position of the wiper unit 74. Furthermore, the position where the wiper unit 74 moves in the +Y direction relative to the lateral frame 32 is referred to as the advanced and extended position of the wiper unit 74. The wiper unit 74 retracts in the -Y direction relative to the lateral frame 32 when the cover unit 62 covers the line head 40 and when the line head 40 is recording.

[0102] The driving unit 80 includes, for example, a motor 82 and a belt 84 to which the wiper unit 74 is attached. The belt 84 circulates due to the rotation of the motor 82 , thereby moving the wiper unit 74 in the Y direction.

[0103] Thus, the wiper unit 74 is provided so as to be able to move the wiper to the line head 40 and the transport unit 10 (see Figure 1 ) between the line head 40 and the direction B and the direction A and move forward and backward in the Y direction intersecting the direction B and the direction A, and cleans the line head 40 when the line head 40 is located in the retracted position described later.

[0104] like Figure 3 As shown, the side frame 32 is provided with a guide member 91 as an example of a guide member for guiding the line head 40 in the B direction.

[0105] The guide member 91 is divided in the B direction by the through hole 33. In other words, the guide member 91 is divided into the second movement area S2 (see Figure 8 ), and is divided in the direction B. Specifically, the guide member 91 is composed of a first guide member 92 and a second guide member 96 .

[0106] The first guide member 92 is provided at a portion of the side frame 32 facing the through hole 33 in the -B direction. The first guide member 92 includes a guide rail 93 as an example of a longitudinal groove portion.

[0107] The guide rail 93 is formed in a U-shaped cross section that opens in the +Y direction toward the line head 40 and extends substantially linearly with the B direction as the guide direction. The guide rail 93 guides the rollers 45A and 45B of the protrusion 44 in the B direction.

[0108] Specifically, the guide rail 93 includes a bottom wall 93A arranged along the XZ plane and a pair of side walls 93B extending from both ends of the bottom wall 93A in the A direction toward the Y direction. The ends of the guide rail 93 in the -B direction are open toward the +Z direction. The ends of the guide rail 93 in the +B direction are located at the edge of the through-hole 33 and open toward the through-hole 33. A restrictor 94 is formed between the center and the ends of the guide rail 93 in the +B direction.

[0109] The restricting portion 94 is a portion that protrudes from the side wall 93B in the -A direction toward the inside of the guide rail 93. The restricting portion 94 is located in the +B direction relative to the roller 45B and restricts movement of the roller 45B relative to the restricting portion 94 in the +B direction.

[0110] A widened portion K is formed in a portion of the guide rail 93 in the -B direction relative to the restricting portion 94, which is wider in the A direction than the rest of the portion. The width of the guide rail 93 in the A direction in the widened portion K is referred to as width WA. Furthermore, the width of the guide rail 93 in the +B direction relative to the restricting portion 94 is referred to as width WB. Here, width WA is wider than width WB. Furthermore, the lengths in the A direction corresponding to widths WA and WB are longer than the lengths corresponding to the diameters of rollers 45A and 45B, respectively.

[0111] A notch is formed in a portion of the side wall 93B in the +A direction, which is located closer to the +B direction than the restricting portion 94. One end portion of the guide rail 95 is connected to the notch portion of the side wall 93B.

[0112] The guide rail 95 is formed in a U-shaped cross section that opens in the +Y direction, and has the same width as the guide rail 93. The guide rail 95 extends from a merging portion with the guide rail 93 in the +Z direction.

[0113] Here, the roller 45B is guided in the −B direction by the guide rail 93 and then in the +Z direction, and the roller 45A is guided in the +Z direction by the guide rail 95 , so that the line head 40 is separated from the first guide member 92 in the +Z direction.

[0114] The second guide member 96 is provided at a position in the +B direction relative to the through hole 33 of the lateral frame 32. The second guide member 96 includes a guide rail 97 as an example of a longitudinal groove portion that guides the line head 40 in the B direction, and a guide rail 98 as an example of a transverse groove portion that intersects the guide rail 97 and guides the cover unit 62 in the A direction.

[0115] Guide rail 97 extends in the B direction. Guide rail 98 extends in the A direction. As an example of an intersection, guide rails 97 and 98 are orthogonal. The intersection of guide rails 97 and 98 is referred to as intersection 99. Intersection 99 is located at the end of guide rail 97 in the -B direction. In other words, guide rails 97 and 98 are arranged in a T-shape.

[0116] Guide rail 97 is formed in a U-shaped cross section that opens in the +Y direction toward line head 40 and extends linearly with the B direction as the guide direction. The central axis of guide rail 97 is substantially aligned with the central axis of guide rail 93. The length of guide rail 97 in the B direction is shorter than the length of guide rail 93 in the B direction. Therefore, guide rail 97 is formed to guide roller 45A only in the B direction.

[0117] Specifically, guide rail 97 includes a bottom wall 97A arranged along the XZ plane and a pair of side walls 97B extending from both ends of bottom wall 97A in the A direction toward the Y direction. The ends of guide rail 97 in the -B direction are open toward the +Z direction. The ends of guide rail 97 in the +B direction are closed. Furthermore, the width of guide rail 97 in the A direction is substantially the same as width WB. The height of side wall 97B in intersection 99 is lower than the height of side wall 97B in the +B direction relative to intersection 99. In other words, the depth of guide rail 97 in the Y direction is deeper than the depth of guide rail 98 in the Y direction.

[0118] Guide rail 98 is formed into a U-shaped cross-section that opens in the +Y direction toward cover unit 62 and extends linearly with direction A serving as the guide direction. Guide rail 98 is also divided at intersection 99. The length of guide rail 98 in the +A direction relative to intersection 99 is shorter than the length of guide rail 98 in the -A direction relative to intersection 99. Therefore, guide rail 98 in the +A direction relative to intersection 99 is formed to guide only roller 69A in the A direction.

[0119] Specifically, guide rail 98 includes a bottom wall 98A arranged along the XZ plane and a pair of side walls 98B extending from both ends of bottom wall 98A in the B direction in the Y direction. Both ends of guide rail 98 in the A direction are open. The length corresponding to the width of guide rail 98 in the B direction is longer than the length corresponding to the diameter of rollers 69A, 69B, and 69C. The height of side wall 98B in the Y direction is lower than the height of side wall 97B in the Y direction.

[0120] like Figure 4 As shown, the side frame 34 is provided with a guide member 102 as an example of a guide member.

[0121] The guide member 102 includes a guide rail 104 that guides the line head 40 in the B direction, a guide rail 105 that extends from a portion of the guide rail 104 in the Z direction, and a guide rail 106 that intersects the guide rail 104 and guides the cover unit 62 in the A direction. The guide rail 104 is an example of a longitudinal groove, and the guide rail 106 is an example of a transverse groove.

[0122] The guide rail 104 extends in the direction B. The guide rail 106 extends in the direction A. As an example of intersection, the guide rail 104 and the guide rail 106 are perpendicular to each other. The portion where the guide rail 104 and the guide rail 106 intersect is referred to as an intersection 107 .

[0123] The guide rail 104 is formed into a U-shaped cross section that opens in the +Y direction toward the line head 40 and extends linearly with the B direction as the guide direction. The guide rail 104 is not divided by the intersection 107. That is, the guide rail 104 is continuous in the B direction at the intersection 107. The length of the guide rail 104 in the B direction is longer than that of the guide rail 93 (see FIG. Figure 3 ) in the B direction and the guide rail 97 (see Figure 3 ) is longer than the total length of the length in the B direction.

[0124] Specifically, the guide rail 104 includes a bottom wall 104A arranged along the XZ plane and a pair of side walls 104B extending from both ends of the bottom wall 104A in the A direction toward the Y direction. The ends of the guide rail 104 in the -B direction are open toward the +Z direction. The ends of the guide rail 104 in the +B direction are closed.

[0125] The width of the guide rail 104 in the A direction is set to be equal to the width WB (see Figure 3 ) have almost the same width. The height of sidewall 104B in intersection 107 is lower than the height of sidewall 104B outside intersection 107. In other words, the depth of guide rail 104 in the Y direction is deeper than the depth of guide rail 106 in the Y direction.

[0126] Furthermore, the guide rail 104 is provided with a restriction bracket 108 for preventing the roller 45D from falling off the guide rail 104 as an example.

[0127] Guide rail 106 has a U-shaped cross-section that opens in the +Y direction toward cover unit 62 and extends linearly with direction A serving as the guide direction. Guide rail 106 is also divided at intersection 107. The length of guide rail 106 in the +A direction relative to intersection 107 is shorter than the length of guide rail 106 in the -A direction relative to intersection 107. However, guide rail 106 in the +A direction relative to intersection 107 can guide rollers 69D and 69E in the A direction.

[0128] Specifically, guide rail 106 includes a bottom wall 106A arranged along the XZ plane and a pair of side walls 106B extending from both ends of bottom wall 106A in the B direction in the Y direction. Both ends of guide rail 106 in the A direction are open. The length corresponding to the width of guide rail 106 in the B direction is longer than the length corresponding to the diameter of rollers 69D, 69E, and 69F. The height of side wall 106B in the Y direction is lower than the height of side wall 104B in the Y direction.

[0129] Furthermore, the guide rail 106 is provided with a restriction bracket 109 for preventing the rollers 69D, 69E, and 69F from falling off the guide rail 106 as an example.

[0130] like Figure 7 As shown in FIG. 1 , the bottom wall 93A and the bottom wall 97A are located at almost the same position in the +Y direction.

[0131] In the Y direction, the depths of guide rails 93 and 97 are both greater than the depth of guide rail 98. Furthermore, bottom wall 98A is located higher in the +Y direction than bottom wall 93A. The length corresponding to the depth from the surface of bottom wall 93A to the surface of bottom wall 98A is longer than the length corresponding to the width of roller 45 in the Y direction. This prevents roller 45A from becoming misaligned relative to guide rail 97 when roller 45A is guided by side wall 97B at intersection 99.

[0132] right Figure 2 The following describes each position in the B direction when the line head 40 shown is moved by the head moving unit 50 .

[0133] like Figure 9 As shown, the recording position of the line head 40 refers to the stop position of the line head 40 when the line head 40 becomes capable of recording information on the medium P. In addition, the recording position can be adjusted by the adjustment unit 56 ( Figure 6 ) adjustment, so there is more than one.

[0134] The retracted position of the line head 40 is the position where the line head 40 stops when it moves away from the transport unit 10 in the −B direction from the recording position. The retracted positions of the line head 40 include the first position, the second position, the third position, the standby position, and the replacement position described below.

[0135] like Figure 10 As shown, the first position of the line head 40 refers to the position of the line head 40 when the cover portion 64 covers the nozzles N in the B direction.

[0136] like Figure 11As shown, the second position of the line head 40 is a position of the line head 40 when the flushing section 66 orients the nozzles N in the direction B and is spaced apart from the first position.

[0137] like Figure 14 As shown, the third position of the line head 40 is a position of the line head 40 when the wiper unit 74 is capable of cleaning the ejection surface NA of the nozzle N in the B direction.

[0138] Although not shown in the figure, the standby position of the line head 40 is a position farther from the transport unit 10 in the B direction than the first, second, and third positions described above. This is the standby position where the line head 40 waits until the movement of the cover unit 64, rinse unit 66, and wiper unit 74 is complete before moving. Furthermore, the replacement position of the line head 40 is a position farther from the transport unit 10 in the B direction than the standby position. In other words, the replacement position of the line head 40 is the position furthest from the transport unit 10 in the B direction.

[0139] like Figure 12 As shown, when the line head 40 is in the first position and the cover portion 64 (see Figure 10 ) Covering nozzle N (refer to Figure 10 ), roller 45A is located at the +B end of guide rail 93. Roller 45B is located in the -B direction at the center of guide rail 93 in the B direction. Furthermore, rollers 69A and 69B are located in the +A direction of guide rail 98 relative to intersection 99. Roller 69C is located in the -A direction of guide rail 98 relative to intersection 99.

[0140] like Figure 13 As shown, when the line head 40 is in the second position and the flushing section 66 (refer to Figure 11 ) and nozzle N (refer to Figure 11 ), roller 45A is located at the +B direction end of guide rail 93. Roller 45B is located in the -B direction at the B direction center of guide rail 93. Furthermore, rollers 69A, 69B, and 69C are located in the -A direction of guide rail 98 relative to intersection 99.

[0141] like Figure 15 As shown, when the line head 40 is in the replacement position and the cover unit 62 is in the retracted position, the roller 45A is located in contact with the restriction portion 94 of the guide rail 93. The roller 45B is located at the -B direction end of the guide rail 93. The rollers 69A and 69B are located in the -A direction of the intersection 99 of the guide rail 98. The roller 69C is located at the -A direction end of the guide rail 98.

[0142] Note that description of the positions of the rollers 45C and 45D and the rollers 69D, 69E, and 69F in the guide member 102 will be omitted.

[0143] As described above, the head moving unit 50 moves the line head 40 so that the moving direction of the line head 40 intersects both the vertical direction and the horizontal direction.

[0144] In addition, the head moving unit 50 (see Figure 5 ), for example, the line head 40 is configured to be movable to any one of the recording position, the retracted position, the first position, the second position, the third position, the standby position, and the replacement position. Furthermore, the head moving unit 50 is configured to position the line head 40 at the standby position before positioning the line head 40 at any one of the first position, the second position, and the third position.

[0145] like Figure 8 As shown, the cover unit 62 (refer to Figure 2 ) is set as the first moving area S1. In addition, the wiper unit 74 (refer to Figure 6 ) is set as the second moving area S2. Figure 8 In FIG, the first movement area S1 and the second movement area S2 are simplified and represented by rectangular areas.

[0146] In this embodiment, as an example, a portion of the first movement area S1 and the second movement area S2 are arranged at the same position in direction B. In other words, a portion of the first movement area S1 and the second movement area S2 overlap in a range G in direction B when viewed from the Y direction.

[0147] The second movement area S2 penetrates the lateral frame 32 in the Y direction.

[0148] The guide rail 98 is arranged to be offset from the second movement area S2 in the B direction. Specifically, the guide rail 98 is arranged to be offset from the second movement area S2 in the +B direction. In this embodiment, as an example, the guide rail 98 is arranged adjacent to the second movement area S2.

[0149] like Figure 8 As shown, according to the printer 1, the cover unit 62 (refer to Figure 2 ) and at least a portion of the second movement area S2 where the wiper unit 74 moves are arranged at the same position in the direction B. Thus, compared to a configuration in which the first movement area S1 and the second movement area S2 are arranged with the first movement area S1 and the second movement area S2 offset in the direction B, the area required for movement of the cover unit 62 and the wiper unit 74 is reduced, thereby preventing the printer 1 from increasing in size in the direction of movement of the line head 40.

[0150] According to the printer 1, the line head 40 is aligned with the side frame 32 and the side frame 34 in the B direction (see FIG. Figure 4 Here, since the second moving area S2 penetrates the lateral frame 32 in the Y direction, the wiper unit 74 can be retracted outward relative to the lateral frame 32, thereby preventing the moving area of the line head 40 from being narrowed by the wiper unit 74.

[0151] like Figure 3 and Figure 8 As shown, according to the printer 1, since the second movable area S2 is located at a position that divides the first guide member 92 and the second guide member 96, the first guide member 92 and the second guide member 96 that guide the line head 40 can be arranged close to the wiper unit 74 that cleans the nozzle N, thereby miniaturizing the line head 40.

[0152] like Figure 3 and Figure 4 As shown, according to the printer 1, the guide rails 93, 97, 104 surround the rollers 45A, 45B, 45C, 45D except for the opening portion, so that the head moving unit 50 (see Figure 5 ) When the line head 40 is moved in the B direction, the position of the line head 40 can be prevented from being shifted in the A direction or the Y direction.

[0153] like Figure 16 As shown, according to the printer 1, when the roller 45A is located in the second movement area S2 (refer to Figure 8 ), that is, between the guide rails 93 and 97, the roller 45B is guided by the guide rail 93, and the rollers 45C and 45D are guided by the guide rail 104. Thus, the line head 40 is maintained in a supported state regardless of the position of the second movement area S2, thereby preventing the posture of the line head 40 from changing during movement.

[0154] like Figure 3 As shown, according to the printer 1, during the movement of the line head 40 in the -B direction, the roller 45B is located at the widened portion K. As a result, all the rollers 45A, 45B, 45C, and 45D (see FIG. 4 ) are suppressed. Figure 4 ) is located at the narrowest part of the guide rails 93, 97, 104, reducing the load acting on the guide rails 93, 97, 104 from the rollers 45A, 45B, 45C, 45D, thereby preventing a portion of the guide rails 93, 97, 104 from being worn due to the movement of the rollers 45A, 45B, 45C, 45D.

[0155] like Figure 3 and Figure 4As shown, according to the printer 1 , since the guide rails 97 and 98 intersect, and the guide rails 104 and 106 intersect, the line head 40 and the cover unit 62 can be arranged close to each other, and the printer 1 can be miniaturized.

[0156] like Figure 4 As shown, according to the printer 1 , the guide rail 104 is deeper than the guide rail 106 , so that the guide rail 104 is continuously arranged in the B direction at the intersection 107 . This prevents the roller 45C from coming off the guide rail 104 .

[0157] like Figure 17 As shown, according to printer 1, when roller 69A is located in the space of intersection 99, rollers 69B and 69C are guided by guide rail 98, and rollers 69D, 69E, and 69F are guided by guide rail 106. Thus, the cover unit 62 is maintained in a supported state regardless of the position of intersections 99 and 107, thereby preventing the cover unit 62 from changing its posture during movement.

[0158] like Figure 8 As shown, according to the printer 1, since the guide rail 98 is arranged adjacent to the second movement area S2 in the B direction, the cover unit 62 (see Figure 2 ) is arranged close to the line head 40, so that the printer 1 can be miniaturized in the B direction.

[0159] like Figure 1 As shown, according to the printer 1, the head moving unit 50 (refer to Figure 5 ) moves the line head 40 in a direction B that intersects both the vertical and horizontal directions. The gravity acting on the line head 40 in the vertical direction is decomposed into a component force in the +B direction and a component force in the -A direction. The component force acting on the line head 40 in the B direction is smaller than the gravity acting on the line head 40 in the vertical direction, thereby reducing the force required to move the line head 40. Therefore, compared to a configuration in which the line head 40 is moved in the vertical direction, an increase in the load acting on the head moving unit 50 can be suppressed.
