Recording device

Abstract

The present application discloses a recording device. In a configuration in which a maintenance unit is pulled out straight and obliquely upward along the ink ejection surface, the space required to pull out the maintenance unit from the lower side of the line head increases, resulting in a larger device. The maintenance unit that performs maintenance on the recording unit includes: a first guided portion, which is guided by a guide unit; and a second guided portion, which is located in a direction from a retreat position toward a maintenance position, i.e., a first moving direction, relative to the first guided portion. The second guided portion is guided by the guide unit. The guide unit allows the maintenance unit to rotate. This rotation is the rotation of the maintenance unit with the first guided portion as the rotation axis when the maintenance unit moves from the maintenance position to the first moving direction. This rotation is accompanied by the second guided portion disengaging from the guide unit. After the maintenance unit is allowed to rotate, the first guided portion moves in the first moving direction, thereby being able to disengage from the guide unit.

DETAILED DESCRIPTION

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

[0026] The recording device involved in the first embodiment is characterized in that it comprises: a recording unit that ejects liquid onto a medium and records; a maintenance unit that can move along a moving path, the moving path including a maintenance position as a position when maintenance of the recording unit is performed and a retreat position retreated from the maintenance position; and a guide unit that guides the maintenance unit along the moving path, the maintenance unit comprising: a first guided portion that is guided by the guide unit; and a second guided portion that is located in a direction from the retreat position toward the maintenance position, i.e., a first moving direction, relative to the first guided portion, the second guided portion is guided by the guide unit, the guide unit allows the maintenance unit to rotate, the rotation being a rotation around the first guided portion as the rotation axis when the maintenance unit moves from the maintenance position to the first moving direction, and the rotation being a rotation accompanied by the second guided portion disengaging from the guide unit, the first guided portion moving in the first moving direction after the maintenance portion is allowed to rotate, thereby being able to disengage from the guide unit.

[0027] According to this embodiment, when the maintenance unit moves from the maintenance position in the first movement direction, it can rotate using the first guided portion as the rotation axis. This rotation first causes the second guided portion to detach from the guide unit, and then the first guided portion to move in the first movement direction, thereby detaching from the guide unit. This reduces the space required for removing the maintenance unit, compared to a configuration in which the first and second guided portions are detached from the guide unit by moving the maintenance unit straight in the first movement direction, thereby reducing the size of the device.

[0028] The second mode is characterized in that, in the first mode, the guide unit comprises: a lower guide portion, which supports the first guided portion and the second guided portion between at least the retreat position and the maintenance position in the moving path; and an upper guide portion, which is located on the upper side relative to the lower guide portion, and when the maintenance portion moves from the maintenance position to the first moving direction, the second guided portion is released from the constraint formed by the upper guide portion, allowing the rotation of the maintenance portion accompanied by the upward movement of the second guided portion.

[0029] According to this method, when the maintenance part moves from the maintenance position to the first moving direction, the second guided part is released from the constraint formed by the upper guiding part, allowing the rotation of the maintenance part accompanied by the upward movement of the second guided part. Therefore, the maintenance part can be rotated toward the upper side, that is, the maintenance part can be removed from the upper side, thereby facilitating the operation of removing the maintenance part.

[0030] It should be noted that the upward movement of the second guided portion does not necessarily mean that the second guided portion must move straight upward in the vertical direction, but only means that the second guided portion may move as long as a component in the vertical direction is included.

[0031] The third mode is characterized in that, in the second mode, the first guided portion is arranged on the side of the maintenance portion in a cross direction intersecting the moving direction of the maintenance portion and in a first direction serving as one direction of the cross direction, and on the side of the maintenance portion in a second direction serving as another direction of the cross direction, the second guided portion is arranged on the side of the first direction and the side of the second direction in the cross direction, and the guiding unit is arranged at a position in the first direction and the second direction relative to the maintenance portion in the cross direction.

[0032] According to this aspect, the first guided portion and the second guided portion are provided on both sides of the maintenance portion in the intersecting direction and are guided by the guide unit. Therefore, the maintenance portion can stably move along the movement path.

[0033] The fourth mode is characterized in that, in the third mode, the first guided portion arranged on the side of the first direction has a first contact portion that contacts the guiding unit, and the first guided portion arranged on the side of the second direction has a second contact portion that contacts the guiding unit, and when viewed from the cross direction, the first contact portion and the second contact portion are located in overlapping positions.

[0034] According to this embodiment, the first contact portion and the second contact portion are located at overlapping positions when viewed from the intersecting direction. Therefore, when the maintenance unit rotates with the first guided portion, that is, the first contact portion and the second contact portion, as fulcrums, it can rotate stably. In addition, the space required for the rotation of the first and second contact portions can be reduced, thereby preventing an increase in size.

[0035] The fifth mode is characterized in that, in the third or fourth mode, the second guided portion provided on the side of the first direction and the second guided portion provided on the side of the second direction have at least one contact portion that contacts the guide unit, and at least one of the second guided portion provided on the side of the first direction and the second guided portion provided on the side of the second direction has a plurality of the contact portions, and when viewed from the cross direction, the contact portion constituting the second guided portion provided on the side of the first direction and the contact portion constituting the second guided portion provided on the side of the second direction do not overlap.

[0036] According to this embodiment, when viewed from the intersecting direction, all contact portions constituting the second guided portion do not overlap. Consequently, the contact portions constituting the second guided portion are arranged at offset positions along the movement direction of the maintenance unit. In other words, the guide unit supports the maintenance unit over a wide range along the movement direction. Therefore, even if the maintenance unit is subjected to external force from the recording unit, the maintenance unit can maintain its posture stably.

[0037] The sixth mode is characterized in that, in the fifth mode, the lower guide portion is composed of a first lower guide portion and a second lower guide portion, the second lower guide portion is located at a position spaced apart from the first lower guide portion in the first moving direction, and when the maintenance portion is located at the maintenance position, the first guided portion is supported by the first lower guide portion, and a part of the second guided portion is supported by the second lower guide portion.

[0038] According to this embodiment, the lower guide portion is composed of a first lower guide portion and a second lower guide portion, so there is a possibility that the second guided portion may be inserted between the first and second lower guide portions. However, with the fifth embodiment described above, the contact portions constituting the second guided portion are arranged at offset positions along the movement direction of the maintenance portion, thereby preventing the second guided portion from being inserted between the first and second lower guide portions.

[0039] A seventh aspect is characterized in that, in the fifth or sixth aspect, the maintenance unit includes a pressed portion that receives a pressing force from a liquid ejection surface of the recording unit from which liquid is ejected, and when viewed from a direction normal to the liquid ejection surface, the pressed portion overlaps a line connecting one contact portion of the second guided portion disposed on the side portion in the first direction with one contact portion of the second guided portion disposed on the side portion in the second direction. Furthermore, the maintenance unit includes: a pressed portion that receives a pressing force from the liquid ejection surface from which liquid is ejected; and a main body portion that supports the pressed portion and includes the first and second guided portions, and when viewed from a direction normal to the liquid ejection surface, the pressed portion overlaps a line connecting one contact portion of the second guided portion disposed on the side portion in the first direction with one contact portion of the second guided portion disposed on the side portion in the second direction.

[0040] According to this method, when viewed from the normal direction with respect to the liquid ejection surface, the cover portion overlaps with a line connecting a contact portion of the second guided portion constituting the side portion provided in the first direction and a contact portion of the second guided portion constituting the side portion provided in the second direction. Therefore, when the pressed portion is subjected to pressing force from the liquid ejection surface, the pressing force can be properly borne by the multiple contact portions constituting the second guided portion, thereby stabilizing the posture of the pressed portion.

[0041] An eighth aspect is characterized in that, in the seventh aspect, the pressed portion is a cover portion that covers the liquid ejection surface.

[0042] According to this aspect, in a configuration in which the pressed portion is a cover portion that covers the liquid ejection surface, the effects of the seventh aspect can be obtained.

[0043] The ninth mode is characterized in that, in any one of the second to eighth modes, the moving path from the retreat position toward the maintenance position includes a vertically upward component, and the center of gravity position of the maintenance part in the moving direction of the maintenance part is located at a position closer to the first moving direction than the center position of the maintenance part in the moving direction.

[0044] According to this method, the moving path from the retreat position toward the maintenance position includes a vertically upward component, and the center of gravity of the maintenance part in the moving direction of the maintenance part is located at a position in the maintenance part close to the first moving direction. Therefore, when taking out the maintenance part from above, the heavier side is picked up first, which makes it easier to take out the maintenance part compared to the opposite situation.

[0045] A tenth aspect is characterized in that, in any one of the second to ninth aspects, a medium conveyance path for conveying the medium is curved downstream of the recording unit to intersect with the movement path when the movement path is extended in the first movement direction.

[0046] According to this method, the medium conveying path for conveying the medium is bent downstream of the recording part and intersects with the moving path when the moving path is extended in the first moving direction. Therefore, there is a possibility that the maintenance part and the medium conveying path will interfere with each other when the maintenance part is taken out. However, due to the effect of the above-mentioned first method, the maintenance part is taken out in a manner that the maintenance part rotates, so that the interference between the maintenance part and the medium conveying path can be avoided.

[0047] The eleventh mode is characterized in that, in any one of the second to tenth modes, it comprises: a medium receiving portion, which is located vertically above the recording portion, and receives the medium discharged after recording, and a part or all of the medium receiving portion is constructed to be detachable or openable and closable, and the maintenance portion can be taken out of the device by removing or opening a part or all of the medium receiving portion.

[0048] According to this embodiment, the maintenance unit can be taken out of the device by removing or opening part or all of the medium receiving unit. Therefore, an opening for taking the maintenance unit out of the device can be ensured, and the maintenance unit can be easily taken out and installed.

[0049] A twelfth aspect is characterized in that, in any one of the second to eleventh aspects, a conveyor belt is provided for conveying the medium to a position facing the recording unit, and the maintenance unit rotates so that the second guided portion moves in a direction away from the conveyor belt.

[0050] According to this embodiment, the conveyor belt is provided to convey the medium to a position opposite to the recording unit, and the maintenance unit rotates in such a manner that the second guided portion moves in a direction away from the conveyor belt. Therefore, the possibility of the maintenance unit colliding with the conveyor belt and causing damage to the conveyor belt can be reduced.

[0051] The thirteenth mode is characterized in that, in any one of the second to eleventh modes, the recording portion is capable of moving between a recording position and a separation position, the recording position being a position when recording is performed on a medium, the separation position being a position separated from the recording position to increase the distance from the medium, the recording position of the recording portion being limited by the recording portion abutting against a position limiting component, and the maintenance portion rotates in such a manner that the second guided portion moves in a direction away from the position limiting component.

[0052] According to this aspect, the maintenance unit rotates so that the second guided portion moves away from the position regulating member. Therefore, the possibility of the maintenance unit colliding with the conveyor belt and damaging the conveyor belt can be reduced.

[0053] Hereinafter, the present invention will be described in detail.

[0054] Hereinafter, an inkjet printer 1 will be described as an example of a recording device. The inkjet printer 1 performs recording by ejecting ink, an example of liquid, onto a medium represented by recording paper. Hereinafter, the inkjet printer 1 will be simply referred to as a printer 1.

[0055] It should be noted that the XYZ coordinate system shown in the figures is an orthogonal coordinate system. The Y-axis direction is the width of the medium, intersecting the medium's conveyance direction and also the depth direction of the device. The +Y direction, indicated by the arrow, is the direction from the front of the device toward the back. Furthermore, the -Y direction, which is opposite to the +Y direction, is the direction from the back of the device toward the front. Furthermore, the Y-axis direction intersects the direction of movement of the cover carriage 60, described later. The -Y direction is an example of a first direction, and the +Y direction is an example of a second direction.

[0056] The X-axis direction is the width of the printer. When viewed from the printer 1 operator, the +X direction (arrowed direction) is the left side, and the -X direction (opposite to it) is the right side. The Z-axis direction is the vertical direction, or the height of the printer. The +Z direction (arrowed direction) is the upward direction, and the -Z direction (opposite to it) is the downward direction. Unless otherwise specified, "up" refers to the +Z direction, and "down" refers to the -Z direction.

[0057] In addition, the G-axis direction is the normal direction of the ink ejection surface 102 of the line head 101 described later, and the direction indicated by the arrow, i.e., the +G direction, is the direction in which the head unit 100 described later is separated from the conveyor belt 13, and the opposite -G direction is the direction in which the head unit 100 and the conveyor belt 13 are approaching each other.

[0058] The F-axis direction is parallel to the ink ejection surface 102 and represents the direction in which the medium is transported at a position opposite the ink ejection surface 102. The direction indicated by the arrow, i.e., the +F direction, represents the downstream transport direction, while the opposite direction, i.e., the -F direction, represents the upstream transport direction. It should be noted that, hereinafter, the direction in which the medium is transported may be referred to as "downstream," and the opposite direction may be referred to as "upstream."

[0059] The F-axis direction is a moving direction of a cover carriage 60 serving as a maintenance portion described later. The +F direction is a first moving direction, and the −F direction is a second moving direction.

[0060] In addition, in some drawings, for ease of viewing, an FGY coordinate system is shown instead of an XYZ coordinate system.

[0061] exist Figure 1 In FIG, a medium conveyance path is shown by a dotted line. In the printer 1, the medium is conveyed through the medium conveyance path shown by the dotted line.

[0062] The printer 1 includes multiple media cassettes arranged vertically below the main body 2. In this embodiment, the media cassettes are arranged in descending order from the topmost first media cassette 3: a second media cassette 4, a third media cassette 5, and a fourth media cassette 6. Reference symbol P indicates the media stored in each media cassette.

[0063] Each media cassette is provided with a pickup roller for feeding out the stored media. The pickup rollers are denoted by reference numerals 21 , 22 , 23 , and 24 .

[0064] Each media cassette is provided with a feed roller pair that feeds the delivered media diagonally upward. These feed roller pairs are indicated by reference numerals 25, 26, 27, and 28. Furthermore, the second media cassette 4, the third media cassette 5, and the fourth media cassette 6 are provided with a conveying roller pair that conveys the media upward. These conveying roller pairs are indicated by reference numerals 16, 17, and 18.

[0065] In the following, unless otherwise specified, a “roller pair” is constituted by a driving roller driven by a motor (not shown) and a driven roller that rotates in contact with the driving roller.

[0066] The media fed from each media cassette reaches the transport roller pair 29, where it is fed diagonally upward, with both a +X and +Z component, by a transport force applied thereto. The media transport path downstream from the transport roller pair 29 curves upwardly convexly, and the media passes through this curved path before reaching the transport roller pair 30. The media, receiving the transport force from the transport roller pair 30, is fed in the +X direction and reaches the transport roller pair 31 via the curved path, which curves downwardly concavely.

[0067] The medium, receiving a conveying force from the conveyor roller pair 31, is conveyed between a line head 101, an example of a recording unit, and the conveyor belt 13, i.e., to a position opposite the line head 101. The line head 101 performs recording by ejecting ink, an example of a liquid, onto the surface of the medium. The line head 101 is an inkjet head configured so that its nozzles (not shown) ejecting ink cover the entire width of the medium. This allows recording across the entire width of the medium without requiring movement across the width of the medium.

[0068] Reference numeral 10 denotes an ink container for storing ink. Ink ejected by the line head 101 is supplied from the ink container 10 to the line head 101 via a tube (not shown). The ink container 10 is composed of a plurality of ink tanks arranged along the X-axis direction.

[0069] The conveyor belt 13 is an endless belt wound around pulleys 14 and 15. At least one of the pulleys 14 and 15 is driven to rotate by a motor (not shown). The medium is attracted by the surface of the conveyor belt 13 and conveyed to a position facing the line head 101. The medium is attracted to the conveyor belt 13 using known methods such as air suction and electrostatic attraction.

[0070] Here, the medium conveying path passing through the position opposite to the line head 101 is configured to intersect both the horizontal direction and the vertical direction, and convey the medium obliquely upward. Figure 1 The direction includes the −X direction component and the +Z direction component. With this configuration, the horizontal size of the printer 1 can be suppressed.

[0071] Note that, in this embodiment, the medium transport path passing through a position facing the line head 101 is set at an inclination angle of 50° to 70° with respect to the horizontal direction, more specifically, at an inclination angle of 60°.

[0072] The medium on the first surface of which recording has been performed by the line head 101 is further transported obliquely upward by the transport roller pair 32 located downstream of the transport belt 13 .

[0073] A flapper 41 is provided downstream of the conveyor roller pair 32, which switches the media's conveying direction. When directly discharging the media, flapper 41 switches the media's conveying path toward the upward conveyor roller pair 37. A flapper 42 is also provided downstream of the conveyor roller pair 37, which switches the media's conveying path to either discharge from discharge position A1 or to convey to the conveyor roller pair 38 located vertically above. When the media is conveyed toward the conveyor roller pair 38, it is discharged from discharge position A2.

[0074] Media discharged from discharge position A1 is received by discharge tray 8, which is tilted upward with both a +X and +Z component. Discharge tray 8 is located vertically above head unit 100. Media discharged from discharge position A2 is received by an optional tray (not shown).

[0075] When recording is performed on the second side of the medium in addition to the first side, the medium is fed diagonally upward, including both a -X and +Z component, by the baffle 41, passes through the branch position K1, and is then fed from there to the upward turning path. A conveyor roller pair 39 is provided on this turning path. Once the medium enters the turning path, it is conveyed upward by the conveyor roller pair 39. When the rear end of the medium passes the branch position K1, the direction of rotation of the conveyor roller pair 39 is switched, and the medium is then fed downward.

[0076] The medium conveyed downward by the conveying roller pair 39 receives conveying force from the conveying roller pair 33 and the conveying roller pair 34 and reaches the conveying roller pair 30 . Thereafter, the medium is conveyed again by the conveying roller pair 30 to a position facing the line head 101 .

[0077] When the medium is transported again to a position facing the line head 101, the second side opposite to the first side already recorded on is placed opposite the line head 101. Thus, the second side of the medium can be recorded on by the line head 101. The medium with recorded content on the second side is discharged from the aforementioned discharge position A1 or discharge position A2.

[0078] Next, refer to Figure 2 、 Figure 3 、 Figure 4 The operations of the head unit 100 , the cover carriage 60 , and the wiper carriage 110 will be described.

[0079] The head unit 100 is a unit including a line head 101, and is provided so as to be capable of being moved by a head moving motor 117 (see Figure 6 ) and moves in the G-axis direction. It should be noted that the power of the head moving motor 117 is transmitted to the head unit 100 via a rack and pinion mechanism (not shown). Of course, the mechanism for moving the head unit 100 is not limited to the rack and pinion mechanism, and may also be a belt drive mechanism, a screw mechanism, etc.

[0080] In addition, in this embodiment, the head unit 100 is configured to be movable along the G-axis direction, but is not limited to this and may be fixed. In this case, for example, the conveyor belt 13 may be retracted from a position opposite the line head 101, and instead, the cover carriage 60 and wiper carriage 110 (described later) may be moved to a position opposite the line head 101.

[0081] The cap carriage 60 is a unit including a cap 71 that covers the line head 101 and is an example of a maintenance unit for maintaining the line head 101. The cap 71 is an example of a pressed portion that receives a pressing force from the ink ejection surface 102 of the line head 101. The cap carriage 60 is provided so as to be driven by the cap drive motor 67 (see FIG. Figures 11 to 14 ) to move in the F-axis direction. The movement path of the cover carriage 60 includes a retracted position and a maintenance position. The +F direction of the F-axis is the direction from the retracted position toward the maintenance position, i.e., the first movement direction, which will be described in detail later. Furthermore, the -F direction is the direction from the maintenance position toward the retracted position, i.e., the second movement direction.

[0082] The power of the cover drive motor 67 is transmitted to the cover carriage 60 via the rack and pinion mechanism. The rack and pinion mechanism is composed of a rack portion 63b provided on the -Y direction side surface of the cover carriage 60 and a pinion 66A meshing therewith (see Figure 11 、 Figure 13 ) and the rack portion 64b provided on the +Y direction side surface of the cover carriage 60 and the pinion 66B meshing therewith (see Figure 12 、 Figure 14The pinions 66A and 66B are rotated by the power of the cover drive motor 67.

[0083] Of course, the mechanism for moving the cover carriage 60 is not limited to the rack and pinion mechanism, and may be a belt drive mechanism, a screw mechanism, or the like.

[0084] The wiper carriage 110 is a unit in which a wiper 112 for wiping the ink ejection surface 102 of the line head 101 is provided, and is arranged to be driven by a wiper moving motor 116 (see FIG. Figure 6 ) and moves in the Y-axis direction. It should be noted that the power of the wiper moving motor 116 is transmitted to the wiper carriage 110 via a belt drive mechanism (not shown). Of course, the mechanism for moving the wiper carriage 110 is not limited to a belt drive mechanism, and may also be a rack and pinion mechanism, a screw mechanism, etc.

[0085] As described above, the head unit 100 , the cap carriage 60 , and the wiper carriage 110 are provided so as to be movable in directions orthogonal to each other.

[0086] Figure 2 The figure shows the positions of the various units when the line head 101 is recording on a medium. Hereinafter, the position of the head unit 100 in this state is referred to as the ink ejection position. When the head unit 100 is in the ink ejection position, the cap carriage 60 is in a retracted position relative to the head unit 100 in the -F direction, and the wiper carriage 110 is in its initial position set in the +Y direction.

[0087] Figure 3 1 shows the positions of the units when the ink ejection surface 102 is covered by the cover 71. Figure 3 In order to avoid the complexity of the drawings, the wiper slide 110 is omitted. However, in this state, the wiper slide 110 and Figure 2 Similarly, it is located at the initial position set in the +Y direction.

[0088] Next, Figure 3 The position of the head unit 100 shown is referred to as a capping position, and the position of the cover carriage 60 is referred to as a maintenance position.

[0089] When the head unit 100 Figure 2 The ink ejection position moves to Figure 3 When the head unit 100 is in the covering position, Figure 2 The ink ejection position moves to Figure 3The capping position is closer to the +G direction. The position of the head unit 100 at this time is called the cap standby position. When the head unit 100 is in the cap standby position, the cap carriage 60 moves from the retreat position to the maintenance position, whereby the ink ejection surface 102 faces the cap 71. Thereafter, the head unit 100 moves slightly in the -G direction to become Figure 3 In the illustrated covering position, the ink ejection surface 102 is covered by the cover 71 .

[0090] exist Figure 3 In the figure, reference numeral 60-1 indicates the cover carriage 60 before it moves to the maintenance position, that is, the cover carriage 60 in the retracted position. Reference numeral Rt denotes the movement path of the cover carriage 60 when it moves between the retracted position and the maintenance position. Movement path Rt extends along the F-axis at a position in the -G direction relative to the head unit 100 in the cover standby position.

[0091] It should be noted that when the line head 101 performs the flushing operation, the head unit 100 is located at Figure 3 The state shown is slightly moved toward the +G direction, where the ink ejection surface 102 is slightly separated from the cap 71. The position of the head unit 100 at this time is called the flushing position. The flushing position is between the capping position and the cap standby position.

[0092] Figure 4 The position of each unit when the ink ejection surface 102 is wiped by the wiper 112 is shown. Hereinafter, the position of the head unit 100 in this state is referred to as the wiping position. When the head unit 100 is in the wiping position, the cover carriage 60 is as shown in FIG. Figure 2 The position shown is retracted in the −F direction relative to the head unit 100 .

[0093] When the head unit 100 Figure 2 The ink ejection position moves to Figure 4 When the ink ejection surface 102 is wiped, the head unit 100 is moved from the wiping position. Figure 2 The ink ejection position moves to Figure 4 The wiping position is closer to the +G direction. The position of the head unit 100 at this time is called the wiping standby position. When the head unit 100 is in the wiping standby position, the wiper slide 110 moves from the initial position in the +Y direction to the end position in the -Y direction. Thereafter, the head unit 100 moves slightly in the -G direction to become Figure 4 The wiper carriage 110 is shown in the wiping position. In this state, the wiper carriage 110 moves in the +Y direction, and the wiper 112 wipes the ink ejection surface 102 .

[0094] It should be noted that the head unit 100 can be further moved in the +G direction from the wiping position. By moving the head unit 100 further in the +G direction from the wiping position, the head unit 100 can be replaced. In other words, the head unit 100 can be moved between a replacement position closest to the +G direction and an ink ejection position closest to the -G direction.

[0095] Below, refer to Figure 5 The following figures will further explain the cover slide 60 in particular.

[0096] like Figure 5 As shown, the apparatus body 2 includes a frame 43A at the end in the -Y direction and a frame 43B at the end in the +Y direction. The moving unit 45 is fixed to the frames 43A and 43B. The moving unit 45 includes the head unit 100, the cover carriage 60, and the wiper carriage 110.

[0097] like Figure 6 、 Figure 7 As shown, the motion unit 45 includes a front frame 47 and a rear frame 48 located in the +Y direction relative to the front frame 47. The front frame 47 and the rear frame 48 form a frame surface along the XZ plane. The front frame 47 and the rear frame 48 are formed of metal plates.

[0098] The front frame 47 and the rear frame 48 are connected by a first connecting frame 50, a second connecting frame 51, and a third connecting frame 52 extending in the Y-axis direction. The first connecting frame 50, the second connecting frame 51, and the third connecting frame 52 are formed by bending a metal plate.

[0099] In this embodiment, the first connecting frame 50, the second connecting frame 51 and the third connecting frame 52 are joined to the front frame 47 and the rear frame 48 by welding. Figure 7 The frame assembly 46 is shown. It should be noted that, below, for the sake of convenience, the area between the front frame 47 and the rear frame 48 is sometimes referred to as the "inside", and the -Y direction relative to the front frame 47 or the +Y direction relative to the rear frame 48 is sometimes referred to as the "outside".

[0100] like Figures 2 to 4 As shown, the first connecting frame 50 , the second connecting frame 51 and the third connecting frame 52 are bent so that part or all of the cross section becomes square, thereby improving the overall rigidity of the frame assembly 46 , ie, the motion unit 45 .

[0101] It should be noted that if Figures 2 to 4As shown, the first connecting frame 50 is bent in a manner that it extends from a square portion in the -G direction, then extends in the +F direction, and then extends again in the -G direction, thereby forming a state in which the third guide portion 45c is formed integrally. The third guide portion 45c guides the wiper slide 110 in the Y-axis direction. In addition, a fourth guide portion 45d is attached to the second connecting frame 51, and the fourth guide portion 45d is formed in a shape that extends from the second connecting frame 51 in the +G direction and then bends in the -F direction. The fourth guide portion 45d is formed by bending a metal plate in the same manner as other frames, and together with the third guide portion 45c, guides the wiper slide 110 in the Y-axis direction. It should be noted that in Figure 7 In the figure, the fourth guide portion 45d is omitted.

[0102] like Figure 7 As shown, the third guide portion 45c is extended to the outside of the rear frame 48. That is, the main body of the first connecting frame 50 is extended between the front frame 47 and the rear frame 48, but only the third guide portion 45c is extended to the outside of the rear frame 48. As a result, the wiper carriage 110 can move to the outside of the rear frame 48. It should be noted that the fourth guide portion 45d is also similar to the third guide portion 45c. Figure 6 The illustrated extension is provided to the outside of the rear frame 48 .

[0103] In addition, if Figure 6 and Figure 7 As shown, an opening 48a is formed in the rear frame 48. The opening 48a is formed in a shape that conforms to the outer shape of the wiper carriage 110 when viewed from the Y-axis direction, and is formed larger than the outer shape of the wiper carriage 110. Thus, the wiper carriage 110 can pass through the opening 48a and move between the inside and outside of the rear frame 48.

[0104] A head guide unit is provided inside the front frame 47 and the rear frame 48 along the G-axis direction. Figure 6 and Figure 7 4 , the head guide unit provided on the front frame 47 is indicated by reference numeral 45a, and the head guide unit provided on the rear frame 48 is not visible. The head guide unit 45a guides the head unit 100 in the G-axis direction.

[0105] Furthermore, a cover guide unit is provided inside the front frame 47 and the rear frame 48 along the F-axis direction. Figure 7 In the figure, the cover guide unit provided on the front frame 47 is indicated by reference numeral 90, and the cover guide unit provided on the rear frame 48 is not visible. The cover guide unit 90 guides the cover carriage 60 in the F-axis direction.

[0106] The cover guide unit 90 will be described in detail later.

[0107] Next, the structure of the cover carriage 60 will be described in detail.

[0108] exist Figure 8 In the figure, the cover carriage 60 comprises a main body 61 as its base. The main body 61 is open in the +F and +G directions. Covers 71a, 71b, 71c, 71d, and 71e are provided along the Y-axis relative to the main body 61. In this specification, these multiple covers are referred to as cover 71 unless otherwise specified.

[0109] With respect to the main body 61, a first side frame 63 is erected at the end in the -Y direction, and a second side frame 64 is erected at the end in the +Y direction. Figure 9 As shown, a rack portion 63b is formed along the F-axis direction on the -G direction surface, that is, the bottom surface of the first side frame 63. As described above, the pinion 66A (see Figure 11 、 Figure 13 ) meshes with the rack portion 63b to form a rack and pinion mechanism.

[0110] In addition, if Figure 10 As shown, a rack portion 64b is formed along the F-axis direction on the -G direction surface, that is, the bottom surface of the second side frame 64. As described above, the pinion 66B (see Figure 12 、 Figure 14 ) meshes with the rack portion 64b to form a rack and pinion mechanism.

[0111] like Figure 8 As shown, a first positioning portion 68 is provided on the inner side of the first side frame 63, and a second positioning portion 69 is provided on the inner side of the second side frame 64. The first positioning portion 68 and the second positioning portion 69 respectively abut against abutment pins (not shown) provided on the head unit 100, thereby determining the position of the cover 71 relative to the head unit 100. It should be noted that the engagement between the abutment pins and the first positioning portion 68 and the second positioning portion 69 can be released by moving the head unit 100 to the replacement position.

[0112] It should be noted that if Figure 11 and Figure 12 As shown, the first positioning portion 68 and the second positioning portion 69 are portions that protrude most in the +G direction in the cover carriage 60 .

[0113] like Figure 9 、 Figure 10 As shown, a first guided portion 75 and a second guided portion 80 are provided on the side surface of the first side frame 63 in the -Y direction and the side surface of the second side frame 64 in the +Y direction. The first guided portion 75 and the second guided portion 80 are provided by referring to Figure 7 The outlined cover guide unit 90 is guided to a portion in the F-axis direction.

[0114] Thus, in the Y-axis direction, which intersects the F-axis direction, the first guided portion 75 and the second guided portion 80 are provided on the side surface of the cover carriage 60 that is in the first direction, i.e., the -Y-direction, and on the side surface of the cover carriage 60 that is in the second direction, i.e., the +Y-direction. Thus, the cover carriage 60 can stably move along the F-axis direction.

[0115] It should be noted that the second guided portion 80 may be provided only on one of the side surface in the −Y direction and the side surface in the +Y direction of the cover carriage 60 .

[0116] In the present embodiment, the first guided portion 75 is composed of a first contact portion 76 provided on the first side frame 63 and a second contact portion 77 provided on the second side frame 64 .

[0117] Furthermore, in the present embodiment, the second guided portion 80 is composed of the third contact portion 81 and the fourth contact portion 82 provided on the first side frame 63 , and the fifth contact portion 83 provided on the second side frame 64 .

[0118] The first contact portion 76, the second contact portion 77, the third contact portion 81, the fourth contact portion 82, and the fifth contact portion 83 are areas of contact with the cover guide unit 90 (described later). In this embodiment, they are formed by rotatable follower rollers. The centerline of the follower roller's rotation axis is parallel to the Y-axis. However, the contact portions are not limited to follower rollers and may also be non-rotating areas.

[0119] like Figure 15 As shown, the first contact portion 76 and the second contact portion 77 constituting the first guided portion 75 are arranged so that their positions in the F-axis direction coincide. In other words, the first contact portion 76 and the second contact portion 77 are located at overlapping positions when viewed from the Y-axis direction. Line L1 is a line passing through the first contact portion 76 and the second contact portion 77 and parallel to the Y-axis direction.

[0120] In other words, the third contact portion 81 , the fourth contact portion 82 , and the fifth contact portion 83 are located at positions that do not overlap when viewed from the Y axis.

[0121] Next, the cover guide unit 90 that guides the first guided portion 75 and the second guided portion 80 in the F-axis direction will be described in detail.

[0122] The cover guide unit 90 includes a lower guide portion that supports the first guided portion 75 and the second guided portion 80 at least between the retreat position and the maintenance position in the movement path Rt of the cover carriage 60 , and an upper guide portion that is located above the lower guide portion.

[0123] The lower guide part is composed of Figure 11 、 Figure 13 The front lower guide portion 91 shown in FIG. 1 is located in the -Y direction (the front side of the device) relative to the cover slide 60 and Figure 12 、 Figure 14 The rear lower guide portion 92 shown is located in the +Y direction (on the rear side of the device) relative to the cover carriage 60.

[0124] like Figure 11 、 Figure 13 As shown, the front lower guide portion 91 is composed of a front first lower guide portion 91-1 and a front second lower guide portion 91-2 located at a distance d from the front first lower guide portion 91-1 in the +F direction. Figure 12 、 Figure 14 As shown, the rear lower guide portion 92 is composed of a rear first lower guide portion 92-1 and a rear second lower guide portion 92-2 located at a distance d from the rear first lower guide portion 92-1 in the +F direction. The distance d is for the head guide unit 45a (refer to Figure 7 ) is a gap set across the cover guide unit 90.

[0125] It should be noted that in this embodiment, the front first lower guide portion 91-1 and the front second lower guide portion 91-2 are completely separated and separated by a gap d. However, the front first lower guide portion 91-1 and the front second lower guide portion 91-2 may be connected, and a recess or hole may be formed on the support surface supporting the first guided portion 75 and the second guided portion 80. The relationship between the rear first lower guide portion 92-1 and the rear second lower guide portion 92-2 is similar.

[0126] The upper guide portion is composed of Figure 11 、 Figure 13 The front upper guide portion 93 shown in FIG. 1 is located in the -Y direction (the front side of the device) relative to the cover slide 60 and Figure 12 、 Figure 14 The rear upper guide portion 94 shown is located in the +Y direction (on the rear side of the device) relative to the cover carriage 60. The rear upper guide portion 94 is composed of a rear first upper guide portion 94-1 and a rear second upper guide portion 94-2 located at a distance d from the rear first upper guide portion 94-1 in the +F direction.

[0127] like Figure 11 、 Figure 13 As shown, the first guided portion 75 and the second guided portion 80 arranged on the side surface in the -Y direction relative to the cover slide 60 are supported by the front lower guide portion 91, and, in the configuration area of ​​the front upper guide portion 93, are guided in the F-axis direction while being clamped by the front lower guide portion 91 and the front upper guide portion 93.

[0128] Likewise, if Figure 12 、 Figure 14 As shown, the first guided portion 75 and the second guided portion 80 arranged on the side surface in the +Y direction relative to the cover slide 60 are supported by the rear lower guide portion 92 and are guided in the F-axis direction while being clamped by the rear lower guide portion 92 and the rear upper guide portion 94 in the configuration area of ​​the rear upper guide portion 94.

[0129] As described above, in the Y-axis direction, which intersects the direction of movement of the cover carriage 60, the first guided portion 75 and the second guided portion 80 are provided on the +Y-direction side and -Y-direction side of the cover carriage 60. Furthermore, the cover guide unit 90 is also provided in the -Y-direction and +Y-direction relative to the cover carriage 60 in the Y-axis direction. This configuration allows the cover carriage 60 to stably move along the movement path Rt.

[0130] It should be noted that in this embodiment, the first guided portion 75 and the second guided portion 80 are provided on the side surfaces of the cover carriage 60 in the Y-axis direction. However, for example, they may be provided so as to protrude in the Y-axis direction from the bottom surface (the surface in the -G direction) of the cover carriage 60. In other words, the first guided portion 75 and the second guided portion 80 only need to be provided on both sides of the cover carriage 60 in the Y-axis direction.

[0131] Figure 11 、 Figure 12 The cover carriage 60 is shown in the maintenance position (corresponding to Figure 3 ). In this state, if Figure 11 As shown, the first contact portion 76 constituting the first guided portion 75 and the third contact portion 81 constituting the second guided portion 80 are sandwiched between the front first lower guide portion 91-1 and the front upper guide portion 93. The fourth contact portion 82 constituting the second guided portion 80 is offset from the front upper guide portion 93 in the +F direction and supported by the front second lower guide portion 91-2.

[0132] In addition, if Figure 12 As shown, the second contact portion 77 constituting the first guided portion 75 and the fifth contact portion 83 constituting the second guided portion 80 are in a state of being sandwiched between the rear lower guide portion 92 and the rear upper guide portion 94 .

[0133] As described above, when the cover carriage 60 is located at the maintenance position, the cover carriage 60 is unable to rotate when viewed from the Y-axis direction.

[0134] From this state, the head unit 100 moves to the replacement position in the +G direction, and then the cover carriage 60 moves in the +F direction. Figure 11 It is clear that the third contact portion 81 deviates from the front upper guide portion 93 in the +F direction. Figure 12It is clear that the fifth contact portion 83 deviates from the rear upper guide portion 94 (the rear second upper guide portion 94-2) in the +F direction. As a result, the cover slide 60 can use the first guided portion 75, that is, the first contact portion 76 and the second contact portion 77 as the rotation axis. Figure 13 、 Figure 14 As shown, the cover carriage 60 rotates in the direction of arrow a. The rotation of the cover carriage 60 in the direction of arrow a is accompanied by the second guided portion 80 being separated from the cover guide unit 90.

[0135] When the cover carriage 60 is rotated in the direction of arrow a and further moved in the +F direction, Figure 13 It is clear that the first contact portion 76 deviates from the front upper guide portion 93 in the +F direction, and Figure 14 It is clear that the second contact portion 77 is offset from the rear upper guide portion 94 (rear second upper guide portion 94-2) in the +F direction. This allows the cover carriage 60 to be pulled out upward.

[0136] It should be noted that when installing the cover slide 60 , the installation can be performed in the reverse order of the above-mentioned extraction.

[0137] As described above, the cover carriage 60 includes the first guided portion 75 guided by the cover guide unit 90 and the second guided portion 80 located in the direction from the retracted position toward the maintenance position relative to the first guided portion 75 , that is, in the +F direction, and guided by the cover guide unit 90 .

[0138] The cover guide unit 90 is configured to allow the cover carriage 60 to rotate about the first guided portion 75 as a rotation axis when the cover carriage 60 moves in the +F direction from the maintenance position. This rotation is accompanied by the second guided portion 80 being disengaged from the cover guide unit 90. After the cover carriage 60 is allowed to rotate, the first guided portion 75 moves in the +F direction, thereby disengaging from the cover guide unit 90.

[0139] That is, compared with a configuration in which the first and second guided portions 75 and 80 are separated from the cover guide unit 90 by moving the cover carriage 60 straight in the +F direction, the space required for removing the cover carriage 60 can be reduced, thereby suppressing an increase in the size of the device.

[0140] Furthermore, when the cover carriage 60 moves from the maintenance position in the +F direction, the second guided portion 80 is released from the restraint formed by the front upper guide portion 93 and the rear upper guide portion 94. This allows the cover carriage 60 to rotate as the second guided portion 80 moves upward, allowing the cover carriage 60 to be rotated upward, that is, the cover carriage 60 can be removed from the upper side, thereby facilitating removal of the cover carriage 60.

[0141] Furthermore, since the first contact portion 76 and the second contact portion 77 are located at overlapping positions when viewed in the Y-axis direction, the cover carriage 60 can stably rotate about the first contact portion 76 and the second contact portion 77. Furthermore, the space required for the rotation of the first contact portion 76 and the second contact portion 77 can be reduced, thereby preventing an increase in size.

[0142] Furthermore, since the third contact portion 81, the fourth contact portion 82, and the fifth contact portion 83 constituting the second guided portion 80 are located so as not to overlap when viewed in the Y-axis direction, that is, they are arranged at offset positions along the F-axis direction, they are supported by the cover guide unit 90 over a wide range along the F-axis direction. Consequently, even if the cover carriage 60 is subjected to external force from the head unit 100, the posture of the cover carriage 60 can be stably maintained.

[0143] It should be noted that in this embodiment, the second guided portion 80 is composed of three contact portions, but it may also be composed of two contact portions, or may be composed of four or more contact portions. In the case where the second guided portion 80 is composed of two contact portions, when viewed in the Y-axis direction, the contact portion on the side surface in the -Y direction and the contact portion on the side surface in the +Y direction may or may not overlap.

[0144] Furthermore, when the second guided portion 80 is composed of three or more contact portions, a plurality of contact portions may be provided on one or both of the side surfaces in the −Y direction and the side surfaces in the +Y direction.

[0145] Furthermore, the front lower guide portion 91 is composed of a front first lower guide portion 91-1 and a front second lower guide portion 91-2 located at a distance d from the front first lower guide portion 91-1 in the +F direction. Furthermore, the rear lower guide portion 92 is composed of a rear first lower guide portion 92-1 and a rear second lower guide portion 92-2 located at a distance d from the rear first lower guide portion 92-1 in the +F direction. While there is a possibility that the second guided portion 80 may fit within the distance d, the contact portions constituting the second guided portion 80 are arranged with their positions offset along the F-axis, preventing this from happening.

[0146] Note that, since the space d is provided, the space d can be used as a passage area for other components. In the present embodiment, the space d can be used as a passage area for a portion of the head unit 100 , thereby improving design flexibility.

[0147] The cap carriage 60 includes a cap 71 and a main body 61 including a first guided portion 75 and a second guided portion 80 as a portion supporting the cap 71. When viewed from the G-axis direction, which is the normal direction to the ink ejection surface 102, as shown in FIG. Figure 15 As shown, the cover 71 overlaps with a line L2 connecting the third contact portion 81 of the second guided portion 80 disposed on the side in the −Y direction and the fifth contact portion 83 of the second guided portion 80 disposed on the side in the +Y direction.

[0148] Thus, when the cap 71 receives a pressing force in the −G direction from the ink ejection surface 102 , the pressing force can be appropriately received by the plurality of contact portions constituting the second guided portion 80 , thereby stabilizing the posture of the cap 71 .

[0149] It should be noted that in this embodiment, the cap 71 is an example of a pressed portion that receives a pressing force from the ink ejection surface 102 of the line head 101. However, another example of a pressed portion that receives a pressing force from the ink ejection surface 102 is the wiper 112. In other words, the structure of the cap carriage 60 can also be applied to the wiper carriage 110.

[0150] It should be noted that in Figure 15 In FIG, line L3 connects fourth contact portion 82 and fifth contact portion 83. Cover 71 may overlap line L3 instead of line L2, or may overlap both line L2 and line L3. Furthermore, a portion or all of cover 71 may be within the triangular region formed by lines L2 and L3.

[0151] Furthermore, when the third contact portion 81 is not provided, the line L4 connecting the fifth contact portion 83 and the first contact portion 76 may overlap the cover 71. Furthermore, a portion or all of the cover 71 may be within the triangular region formed by the lines L3 and L4.

[0152] Furthermore, in this embodiment, the movement path Rt of the cover carriage 60 from the retreat position toward the maintenance position includes a vertically upward component, as shown in FIG. Figure 11 、 Figure 12 As shown, the center of gravity G of the cover carriage 60 in the movement direction of the cover carriage 60 is closer to the +F direction in the cover carriage 60. Closer to the +F direction means that it is closer to the +F direction than the center position Fc of the cover carriage 60 in the F-axis direction.

[0153] With this configuration, when removing the cover slide 60 from the top, the heavier side is lifted first, and the cover slide 60 can be removed more easily than in the opposite case.

[0154] It should be noted that the movement path Rt of the cover slide 60 may also be along the horizontal direction.

[0155] Note that the first positioning portion 68 and the second positioning portion 69, which are the portions of the cover carriage 60 that protrude most in the +G direction, are also positioned closer to the +F direction. This reduces the area within the device required to remove the cover carriage 60. Furthermore, the cover carriage 60 can be rotated at an early stage when removing it, thereby reducing the space required to remove the cover carriage 60 and preventing an increase in the size of the device.

[0156] In addition, the reference Figure 1 The medium conveying path at the discharge positions A1 and A2 described above bends upward downstream of the line head 101. Figure 3 In FIG. 1 , reference numeral Tr denotes a medium conveyance path that curves upward, and this medium conveyance path Tr intersects with the movement path Rt of the cover carriage 60 when the movement path Rt is extended in the +F direction.

[0157] In such a configuration, there is a possibility that the cover carriage 60 may interfere with the medium conveyance path Tr when the cover carriage 60 is removed. However, as described above, since the cover carriage 60 is removed while rotating, interference between the cover carriage 60 and the medium conveyance path Tr can be avoided.

[0158] In addition, as referenced Figure 1 As described above, the discharge tray 8 serving as a medium receiving portion is provided vertically above the head unit 100. The medium receiving portion receives the medium discharged after recording. Figure 16 and Figure 17 As shown, the discharge tray 8 is detachable from the apparatus body 2. In this embodiment, the entire discharge tray 8 is detachable from the apparatus body 2. In addition, by removing the discharge tray 8 from the apparatus body 2, the cover slide 60 is exposed and can be removed.

[0159] With this configuration, an opening for taking the cover slider 60 out of the device can be ensured, and the cover slider 60 can be easily taken out and attached.

[0160] It should be noted that in this embodiment, the discharge tray 8 is detachable from the device main body 2, but it can also be configured to be openable and closable relative to the device main body 2. In addition, in this embodiment, the entire discharge tray 8 is detachable from the device main body 2, but it can also be configured so that a portion of the discharge tray 8 is detachable from the device main body 2, and further, it can be configured so that a portion of the discharge tray 8 is openable and closable relative to the device main body 2.

[0161] In addition, in this embodiment, Figure 13 、 Figure 14Clearly, the cap carriage 60 can rotate so that the second guided portion 80 moves away from the conveyor belt 13. This reduces the possibility of the cap carriage 60 colliding with the conveyor belt 13 and damaging the conveyor belt 13 when the cap carriage 60 is removed.

[0162] In addition, Figures 11 to 14 In the figure, reference numeral 103 denotes a position adjustment cam, which serves as a position regulating member that regulates the ink ejection position of the head unit 100. The ink ejection position is regulated by the contact between the head unit 100 and the position adjustment cam 103. The position adjustment cam 103 is an eccentric cam that can finely adjust the ink ejection position of the head unit 100 by rotating it.

[0163] Furthermore, the cover carriage 60 rotates so that the second guided portion 80 moves away from the position adjustment cam 103. This configuration prevents the cover carriage 60 from colliding with the position adjustment cam 103 and damaging the position adjustment cam 103 when the cover carriage 60 is removed.
