AI Technical Summary
The existing configuration of image forming apparatuses, where the waste liquid tank and the carriage are located at different positions in the device width direction, leads to a potential increase in the device's width, making it larger than necessary.
The recording device is designed with a recording unit that moves in both horizontal and vertical directions, allowing it to overlap with a recovery unit positioned below it in the vertical direction. This configuration ensures that the movable region of the recording unit and at least a part of the recovery unit overlap in the device width direction when viewed from above, thereby reducing the device's width.
This design effectively reduces the width of the recording device by overlapping the movable regions and recovery units, preventing unnecessary expansion in the device width direction and allowing for a more compact form factor.

[0007] The present invention will now be briefly described. The recording device of the first aspect is movable in a first movement direction having a horizontal component and a device height component, and comprises a recording unit that performs recording by ejecting liquid onto a medium, and a recovery unit that recovers the liquid ejected from the recording unit, wherein the recovery unit is located lower than the recording unit in the device height direction, and when viewed from above to below in the device height direction, the movable area of the recording unit and at least a portion of the recovery unit overlap in the device width direction that intersects with the device height direction. According to this aspect, when viewed from above downward in the device height direction, the movable area and at least a portion of the collection section are arranged to overlap in the device width direction, so that the size of the recording device in the device width direction can be reduced compared to a configuration in which the movable area and the collection section do not overlap in the device width direction.
[0008] The recording device of the second aspect is characterized in that, in the first aspect, the recording device is movable in a second movement direction intersecting the first movement direction, and is provided with a maintenance unit that performs maintenance on the recording unit, the maintenance unit is located lower than the recording unit in the device height direction, and at least a portion of the recovery unit overlaps with the maintenance unit in the device height direction when viewed from the device width direction. According to this aspect, when viewed in the device width direction, the height of the recording device can be made lower than in a configuration in which the movable area of the recording unit and the recovery unit do not overlap in the device height direction.
[0009] The recording device of the third aspect is characterized in that, in the first or second aspect, it is provided with a movement mechanism that moves the recording unit in the first movement direction, and at least a part of the movement mechanism is provided at a position below the movable area and above the recovery unit in the device height direction. According to this aspect, the space between the movable area in the device height direction and the recovery section can be effectively utilized, so that the provision of the movement mechanism section can prevent the recording device from becoming larger in the device height direction.
[0010] The recording device of the fourth aspect is any one of the first to third aspects, and is characterized in that it is provided with a liquid supply section that supplies the liquid to the recording section, and when viewed from the device width direction, at least a portion of the liquid supply section and at least a portion of the recovery section overlap in the device height direction. According to this aspect, when viewed in the apparatus width direction, the height of the recording apparatus can be made lower than in a configuration in which the liquid supply section and the recovery section do not overlap in the apparatus height direction.
[0011] The recording apparatus of the fifth aspect is characterized in that, in the fourth aspect, at least a portion of the liquid supply section overlaps with at least a portion of the movable area in the apparatus height direction when viewed from the apparatus width direction. According to this aspect, when viewed from the apparatus width direction, the height of the recording apparatus can be made lower than in a configuration in which at least a part of the liquid supply portion and at least a part of the movable area do not overlap in the apparatus height direction.
[0012] The recording device of the sixth aspect is the recording device of the fourth or fifth aspect, characterized in that it is provided with a conveying belt that conveys the medium at a position opposite the recording unit, and at least a portion of the conveying belt overlaps with at least a portion of the liquid supply unit in the device height direction when viewed from the device width direction. According to this aspect, the height of the recording apparatus can be made lower than in a configuration in which at least a part of the liquid supply unit and at least a part of the transport belt do not overlap in the apparatus height direction when viewed in the apparatus width direction.
[0013] A recording device according to a seventh aspect is any one of the first to sixth aspects, characterized in that it has a mounting section on which the medium recorded by the recording unit is placed, the mounting section extending in the first movement direction, and when viewed from the device height direction, at least a portion of the mounting section and at least a portion of the movable area overlap in the device width direction. According to this aspect, when viewed from the device height direction, the recording device can be made smaller in the device width direction than in a configuration in which at least a part of the placement section and at least a part of the movable area do not overlap in the device width direction. Furthermore, by extending the placement section in the first movement direction, it is possible to prevent the formation of a wasted space between the placement section and the movable area.
[0014] The recording device of the eighth aspect is characterized in that, in any one of the first to seventh aspects, the angle between the first movement direction and the device width direction is 10° or more and 40° or less. According to this aspect, the movable area of the recording unit is smaller in the device width direction compared to a configuration in which the angle between the first movement direction and the device width direction is smaller than 10°, so that the width of the recording device in the device width direction can be reduced.
[0015] The recording device of the 9th aspect is any one of the first to eighth aspects, characterized in that the recovery section is detachably arranged in a cross direction that intersects with the device width direction when viewed from the device height direction. According to this aspect, since there are fewer members in the attachment / detachment path of the collection unit compared to a configuration in which the collection unit is attached and detached in the height direction of the device, the collection unit can be easily collected.
[0016] The printer 10 will now be described in detail as an example of a recording device according to the present invention. 1, the printer 10 is an example of a recording device that performs recording by ejecting ink Q onto paper P. Note that the XYZ coordinate system shown in each drawing is an orthogonal coordinate system. The paper P is an example of a medium. The ink Q is an example of a liquid.
[0017] The X direction is the depth direction of the device and is also horizontal. The base end side of the arrow indicating the X direction is the -X direction, and the tip end side of the arrow indicating the X direction is the +X direction. The X direction is also the width direction of the paper P. The Y direction is an example of the device width direction and is a horizontal direction. The tip end of the arrow indicating the Y direction is the +Y direction, and the base end of the arrow indicating the Y direction is the -Y direction. The Z direction is an example of the device height direction, and is a direction perpendicular to both the X direction and the Y direction. The tip side of the arrow indicating the Z direction is the +Z direction, and the base side of the arrow indicating the Z direction is the -Z direction. In the following explanation, the +Z direction may be referred to as the upward direction, and the -Z direction may be referred to as the downward direction.
[0018] When viewed from the X direction, the A direction is a direction intersecting the Y direction, and is a diagonal direction in which the position in the -Y direction is lower in the -Z direction than the position in the +Y direction. In other words, the A direction is an example of a first movement direction having a horizontal component and a device height component. The tip side of the arrow indicating the A direction is the +A direction, and the base side of the arrow indicating the A direction is the -A direction. The +A direction is the direction in which the line head 40 described later approaches the conveyor belt 47. The -A direction is the direction in which the line head 40 retreats from the conveyor belt 47.
[0019] When viewed from the X direction, the B direction is a direction perpendicular to the A direction. In other words, the B direction is an example of a second movement direction intersecting the A direction. The tip side of the arrow indicating the B direction is the +B direction, and the base side of the arrow indicating the B direction is the -B direction. The +B direction is the transport direction of the paper P in the recording area between the line head 40 and the transport belt 47.
[0020] A transport path T, indicated by a dashed line, is provided in the device body 12 of the printer 10. Paper P is transported through the transport path T. The transport direction in which paper P is transported is a direction along the transport path T, and is therefore different at each portion of the transport path T. Note that, as an example of paper P, the printer 10 can use paper PA and paper PB, which have different lengths in the transport direction. The length of paper PA in the transport direction is shorter than the length of paper PB in the transport direction.
[0021] The printer 10 includes a device main body 12, a paper cassette unit 16 provided in the device main body 12, a line head 40, and a waste liquid tank 38. The printer 10 further includes a paper output tray 17, an ink supply unit 30, a conveyor belt 47, a cap unit 60, a wiper unit 64, a movement mechanism unit 44, an inverting unit 70, a feeding unit 80, and a control unit (not shown). The device body 12 includes a housing that is an outer shell. An opening 14 that opens in the Y direction is formed at the end of the device body 12 in the -Y direction. A part of a transport path T, which will be described later, can be exposed when the opening 14 is in an open state.
[0022] The paper cassette unit 16 stores paper P. The paper cassette unit 16 includes a first cassette 22, a second cassette 24, and a third cassette 26, for example. The paper P used in the printer 10 includes, for example, paper PA and paper PB that is larger in size than paper PA. The first cassette 22 stores paper sheets PA. The second cassette 24 and the third cassette 26 each store paper sheets PB. The paper sheets P are sent to the transport path T by the rotation of the pickup roller 19 and the roller pair 21.
[0023] The paper discharge tray 17 is provided in a position in the +Z direction from the center in the Z direction of the device body 12. The paper discharge tray 17 is an example of a placement section on which paper P recorded by the line head 40 and discharged is placed. As an example, the paper discharge tray 17 has a bottom wall 17A extending in the A direction, and a vertical wall 17B standing upright in the +B direction at the end of the bottom wall 17A in the +A direction. The multiple sheets of paper P are placed on the bottom wall 17A in a state where they are overlapped in the +B direction. Furthermore, the ends of the multiple sheets of paper P in the +A direction are aligned along the B direction by contacting the vertical wall 17B.
[0024] The transport path T extends from the paper cassette unit 16 to the paper discharge tray 17, and is a path along which the paper P is transported. On the transport path T, a pickup roller 19, roller pairs 21, 23, 25, a transport belt 47, a drive roller 48, a driven roller 49, a roller pair 27, and a discharge roller pair 29 are arranged. Each roller pair is provided so as to be rotatable around an axis along the X direction. The drive roller 48 and the driven roller 49 are arranged at an interval in the B direction, and are rotatable around an axis along the X direction. The drive roller 48 is rotated by a motor (not shown).
[0025] The conveyor belt 47 is formed in a cylindrical shape and is wound around a drive roller 48 and a driven roller 49. The conveyor belt 47 is located in the +A direction relative to the line head 40. The conveyor belt 47 is rotated by the drive roller 48 being rotated by a motor (not shown). The paper P is conveyed in the +B direction by the conveyor belt 47 being rotated while in contact with the outer circumferential surface of the conveyor belt 47. In this manner, the conveyor belt 47 conveys the paper P at a position facing the line head 40.
[0026] The ink supply unit 30 is an example of a supply unit that supplies ink Q to a line head 40 described later. Specifically, the ink supply unit 30 includes, as an example, four ink cartridges 32, a sub-tank 35, a reservoir tank 36, a transport mechanism unit 50 (FIG. 4), and tubes (not shown) that connect each unit. The four ink cartridges 32 store ink Q of different colors.
[0027] As shown in FIG. 4, the ink cartridge 32 is located in the -X direction and +Z direction with respect to the center of the device main body 12 when viewed from the Y direction. The sub-tank 35 is located in the -Z direction relative to the ink cartridge 32. The sub-tank 35 is a tank that temporarily stores the ink Q supplied from the ink cartridge 32. The ink Q in the sub-tank 35 is sent to the ejection unit 42 (FIG. 1), which will be described later. The reservoir tank 36 is located in the +X direction relative to the subtank 35. The reservoir tank 36 stores the ink Q, similar to the subtank 35. The reservoir tank 36 is used to maintain the meniscus of the ejection portion 42 in the line head 40 (FIG. 1) described later.
[0028] The transport mechanism 50 is located inside the device body 12 in the +X direction relative to the ink cartridge 32 and in the +Z direction relative to the reservoir tank 36. The transport mechanism 50 includes a switching valve 52 and a pump motor (not shown). The transport mechanism 50 transports the ink Q in the subtank 35 and the ink Q in the reservoir tank 36 to the line head 40 (FIG. 1) using a tube and a pump (not shown).
[0029] As shown in FIG. 1, the waste ink QW sent from the cap unit 60 and the waste ink QW sent from the wiper unit 64 are transported by a transport mechanism 50 (FIG. 4) to a waste liquid tank 38, which will be described later. The waste liquid tank 38 is replaceably provided at approximately the center of the device body 12 in the Y and Z directions. The waste liquid tank 38 is located below the line head 40 in the Z direction, which will be described later. The waste liquid tank 38 is an example of a recovery section that recovers the ink Q ejected from the line head 40. The ink Q ejected from the line head 40 refers to the ink Q ejected from the line head 40 that did not adhere to the paper P and was not used for recording. In other words, the ink Q ejected from the line head 40 is waste ink QW. As described above, in the waste liquid tank 38, the ink Q recovered in the cap unit 60 and the ink Q recovered in the wiper unit 34 are collected.
[0030] 2, the waste liquid tank 38 is provided so as to be detachable in the X direction, which is an example of a cross direction that crosses the Y direction when viewed from the Z direction. Specifically, the waste liquid tank 38 is removed from the device body 12 by being moved in the -X direction. The waste liquid tank 38 is attached to the device body 12 by being moved in the +X direction relative to the device body 12. The ink cartridge 32, the first cassette 22, the second cassette 24, and the third cassette 26 are also provided detachably in the X direction, which is an example of a cross direction that crosses the Y direction, when viewed from the Z direction.
[0031] 1, the line head 40 is located at a home position before operation. The home position of the line head 40 is, for example, a position in the -Y direction relative to the ink cartridge 32 in the device main body 12, a position below the paper discharge tray 17 in the Z direction, and a position above the paper cassette unit 16 and the waste liquid tank 38 in the Z direction.
[0032] The line head 40 is an example of a recording unit that performs recording by ejecting ink Q onto paper P transported from the paper cassette unit 16 along a transport path T. The line head 40 is driven by a movement mechanism unit 44, which will be described later, and is thus movable in the +A direction and the -A direction, i.e., the A direction. Specifically, the line head 40 includes a carriage 41 driven by the movement mechanism unit 44 and an ejection unit 42 supported by the carriage 41. The ejection unit 42 has a plurality of nozzles (not shown), and ejects the ink Q supplied from the ink supply unit 30 toward the paper P.
[0033] The movement mechanism 44 is a mechanism that moves the line head 40 in the A direction. The movement mechanism 44 is provided in a position in the Z direction below a movable area SA (FIG. 3) described below and above the waste liquid tank 38. The movement mechanism 44 includes, for example, a rack unit 45, a pinion 46, and a motor (not shown). The rack portion 45 is attached to the bottom in the -Z direction of the carriage 41. The rack portion 45 has a plurality of teeth (not shown). The pinion 46 is rotated in a forward or reverse direction by a motor (not shown). A plurality of teeth (not shown) that mesh with a plurality of teeth of the rack portion 45 are formed on the outer periphery of the pinion 46.
[0034] The cap unit 60 is driven by a drive mechanism (not shown) to be capable of reciprocating in the direction B. The cap unit 60 is an example of a maintenance unit that performs maintenance on the line head 40. When the cap unit 60 is located at the home position, it is located lower than the line head 40 in the Z direction. The home position of the cap unit 60 is set in the -B direction with respect to the wiper unit 64 when viewed from the X direction.
[0035] The cap unit 60 is configured in a box shape that opens in the -A direction. When maintenance of the line head 40 is performed, the cap unit 60 moves in the +B direction to cover the ejection portion 42 and suck the ink Q from the ejection portion 42. When recording is performed by the line head 40, the cap unit 60 is retreated to the home position.
[0036] The wiper unit 64 has a unit body 66 capable of containing the ink Q, and a wiper blade 68 that is provided in the unit body 66 and wipes off the ink Q adhering to the ejection portion 42. The wiper unit 64 is capable of reciprocating movement along the X direction by being driven by a drive mechanism (not shown). When maintenance of the line head 40 is performed, the wiper unit 64 collects the ink Q by wiping the surface of the ejection portion 42 while being moved in the +X direction. When recording is performed by the line head 40, the wiper unit 64 is retracted to a home position in the -X direction.
[0037] The control unit (not shown) is configured to include a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage (not shown), and controls the transport of paper P in the printer 10 and the operation of each part including the line head 40.
[0038] The reversing unit 70, for example, has a reversing path R, four roller pairs 72, and a motor (not shown) that drives the four roller pairs 72. The reversing unit 70 then reverses the paper P recorded by the line head 40, and sends the paper P back into the transport path T.
[0039] The feeding unit 80 includes, for example, a feeding tray 82, a feeding roller 84, and a separation roller 86. The feeding unit 80 has a feeding path K in which the feeding roller 84 and the separation roller 86 are arranged. The feeding unit 80 feeds the paper P from the feeding tray 82 to the transport path T via the feeding path K.
[0040] 3, the area through which the line head 40 passes when it moves back and forth in the direction A is defined as the movable area SA of the line head 40. The outline of the movable area SA is indicated by a two-dot chain line SA. In addition, a line passing through the center of the line head 40 and extending in the direction A is defined as a center line CL, which is indicated by a dashed dot line CL. The angle θ between the dashed dotted line CL and the line segment CA along the Y direction is preferably set to be 10° or more and 40° or less. In other words, the angle θ between the A direction and the Y direction is preferably set to be 10° or more and 40° or less. In this embodiment, as an example, the angle θ is set to approximately 15°.
[0041] When viewed from the Z direction, the movable area SA of the line head 40 and part of the waste liquid tank 38 overlap in the Y direction. The range in which the movable area SA and part of the waste liquid tank 38 overlap is a range L1 [mm] in the Y direction. Note that in this embodiment, when viewed from the Z direction means when the object is viewed in the Z direction while facing the -Z direction at a position in the +Z direction relative to the printer 10. Also, when viewed from the Z direction can be said to be when the printer 10 is viewed from above, from the +Z direction toward the -Z direction, that is, when viewed from above. When the line head 40 is located at the home position, a part of the line head 40 and a part of the waste liquid tank 38 overlap in a range L1 in the Y direction when viewed from the Z direction.
[0042] When viewed from the Y direction, a portion of the waste liquid tank 38 overlaps with the cap unit 60 in the Z direction. The range in which a portion of the waste liquid tank 38 overlaps with the cap unit 60 is a range H1 [mm] in the Z direction. As an example, the position of the bottom end of the range H1 corresponds to position Z1, which is the position of the bottom end of the waste liquid tank 38 in the Z direction. As an example, the position of the top end of the range H1 corresponds to position Z2, which is the position of the top end of the waste liquid tank 38 in the Z direction.
[0043] In this embodiment, a view from the Y direction refers to a view of an object in the Y direction while facing the -Y direction at a position in the +Y direction relative to the printer 10, or while facing the +Y direction at a position in the -Y direction relative to the printer 10. A view from the Y direction can also be referred to as a view of the printer 10 from the side, from the +Y direction toward the -Y direction, or from the -Y direction toward the +Y direction, i.e., a side view.
[0044] When viewed from the Y direction, a portion of the ink supply unit 30 and the waste liquid tank 38 overlap in the Z direction. The range in which a portion of the ink supply unit 30 and the waste liquid tank 38 overlap is a range H2 [mm] in the Z direction. As an example, the position of the lower end of the range H2 corresponds to the position Z1 described above. As an example, the position of the upper end of the range H2 corresponds to the position Z2 described above. In this embodiment, as an example, the lower ends of the ranges H1 and H2 are at approximately the same height in the Z direction. Also, in this embodiment, as an example, the ranges H1 and H2 are ranges of approximately the same size.
[0045] When viewed from the Y direction, a portion of the ink supply unit 30 overlaps with the movable area SA in the Z direction. The range in which a portion of the ink supply unit 30 overlaps with the movable area SA is a range H3 [mm] in the Z direction. As an example, the position of the lower end of the range H3 corresponds to a position Z4 which is the position of the lower end of the movable area SA in the Z direction. As an example, the position of the upper end of the range H3 corresponds to a position Z6 which is the position of the upper end of the movable area SA in the Z direction. As an example, the range H3 is wider than both the range H1 and the range H2.
[0046] When viewed from the Y direction, the conveyor belt 47 overlaps with a part of the ink supply unit 30 in the Z direction. The range in which the conveyor belt 47 and the ink supply unit 30 overlap is a range H4 [mm] in the Z direction. As an example, the lower end position of the range H4 corresponds to a position Z3 which is the lower end position of the conveyor belt 47 in the Z direction. As an example, the upper end position of the range H4 corresponds to a position Z5 which is the upper end position of the conveyor belt 47 in the Z direction. Note that the larger the number attached to Z for the positions Z1, Z2, Z3, Z4, Z5, and Z6, the higher the position. As an example, the range H4 is narrower than the range H3. When viewed from the Z direction, a part of the discharge tray 17 and a part of the movable area SA overlap in the Y direction. The range in which the part of the discharge tray 17 and a part of the movable area SA overlap is a range L2 [mm] in the Y direction. The range L2 is wider than the range L1.
[0047] Next, a description will be given of the operation of the printer 10. Note that for the configuration of each part of the printer 10, please refer to Figures 1 to 4, and the description of individual figure numbers will be omitted. According to the printer 10, when viewed from the Z direction, the movable area SA and a portion of the waste liquid tank 38 overlap in the Y direction, so the size of the printer 10 in the Y direction can be made smaller than in a configuration in which the movable area SA and the waste liquid tank 38 do not overlap in the Y direction.
[0048] According to the printer 10, when viewed from the Y direction, the height of the printer 10 can be made lower than in a configuration in which the movable area SA of the line head 40 and the waste liquid tank 38 do not overlap in the Z direction. According to the printer 10, the space between the movable area SA in the Z direction and the waste liquid tank 38 can be effectively utilized, so providing the movement mechanism 44 can prevent the printer 10 from becoming large in size in the Z direction.
[0049] According to the printer 10, when viewed from the Y direction, the height of the printer 10 can be made lower than in a configuration in which the ink supply unit 30 and the waste liquid tank 38 do not overlap in the Z direction. According to the printer 10, when viewed from the Y direction, the height of the printer 10 can be made lower than in a configuration in which a portion of the ink supply unit 30 and the movable area SA do not overlap in the Z direction.
[0050] According to the printer 10, when viewed from the Y direction, the height of the printer 10 can be made lower than in a configuration in which a portion of the ink supply unit 30 and the transport belt 47 do not overlap in the Z direction. According to the printer 10, when viewed from the Z direction, the printer 10 can be made smaller in the Y direction compared to a configuration in which a part of the paper output tray 17 and a part of the movable area SA do not overlap in the Y direction. Furthermore, by extending the paper output tray 17 in the A direction, it is possible to prevent the formation of wasted space between the paper output tray 17 and the movable area SA.
[0051] According to the printer 10, the movable area SA of the line head 40 is smaller in the Y direction compared to a configuration in which the angle between the A direction and the Y direction is less than 10°, so the width of the printer 10 in the Y direction can be reduced. With this configuration, the horizontal and vertical sizes of the spaces required for the movement of the line head 40 can be balanced, and the device can be prevented from becoming extremely large in both the horizontal and vertical directions. According to the printer 10, compared to a configuration in which the waste liquid tank 38 is attached and detached in the Z direction, there are fewer members in the attachment and detachment path of the waste liquid tank 38, making it easier to collect the waste liquid tank 38.
[0052] The printer 10 according to the embodiment of the present invention is based on the configuration described above, but it is of course possible to modify or omit parts of the configuration without departing from the spirit of the present invention.
[0053] When viewed from the Z direction in the printer 10, the movable area SA may overlap the entire waste liquid tank 38. When viewed from the Y direction, the entire waste liquid tank 38 may overlap the cap unit 60. A part of the movement mechanism 44 may be provided at a position below the movable area SA and above the waste liquid tank 38 in the Z direction. When viewed from the Y direction, the entire ink supply unit 30 and the waste liquid tank 38 may overlap in the Z direction.
[0054] In the printer 10, when viewed from the Y direction, a part of the ink supply unit 30 may overlap a part of the movable area SA in the Z direction. Also, when viewed from the Y direction, the entire ink supply unit 30 may overlap the entire movable area SA in the Z direction. When viewed from the Y direction, a part of the transport belt 47 may overlap a part of the ink supply unit 30 in the Z direction. Also, when viewed from the Y direction, the entire transport belt 47 may overlap the entire ink supply unit 30 in the Z direction. When viewed from the Z direction, a part of the discharge tray 17 and the entire movable area SA, or the entire discharge tray 17 and a part of the movable area SA may overlap in the Y direction. Alternatively, when viewed from the Z direction, the entire discharge tray 17 and the entire movable area SA may overlap in the Y direction.
[0055] In the printer 10, when viewed from the Y direction, a portion of the waste liquid tank 38 does not have to overlap with the cap unit 60 in the Z direction. The movement mechanism 44 does not have to be provided in a position below the movable area SA and above the waste liquid tank 38. In this case, when viewed from the Y direction in the printer 10, a part of the waste liquid tank 38 may overlap with the movable area SA in the Z direction. For example, when the line head 40 is located at the recording position, a part of the waste liquid tank 38 may overlap with the line head 40 in the Z direction when viewed from the Y direction. When viewed from the Y direction, a part of the ink supply unit 30 and the waste liquid tank 38 do not have to overlap in the Z direction. A part of the ink supply unit 30 does not have to overlap with the movable area SA in the Z direction.
[0056] In the printer 10, when viewed from the Y direction, the conveyor belt 47 does not have to overlap with a part of the ink supply unit 30 in the Z direction. When viewed from the Z direction, a part of the paper output tray 17 and a part of the movable area SA do not have to overlap with each other in the Y direction. The angle θ is preferably set to be greater than or equal to 10° and less than or equal to 40°. With this configuration, it is possible to ensure the space required for movement of the line head 40 while also ensuring the space required for disposing the waste liquid tank 38 below the line head 40 in the Z direction. As a result, the size of the printer 10 in the Y direction can be made smaller. The angle θ may be greater than 0° and less than 10°, or greater than 40° and equal to or less than 80°. The waste liquid tank 38 does not have to be provided detachably in the X direction. The recovery section is not limited to a tank-shaped one like the waste liquid tank 38, but may be configured as a box-shaped or dish-shaped member with a portion open.
[0057] As shown in Fig. 3, when the line head 40 is located at the furthest position in the +Y direction in the movable area SA, the line head 40 is configured to be able to be pulled out upward. This allows the line head 40 to be replaced. Hereinafter, the furthest position of the line head 40 in the +Y direction will be referred to as the replacement position of the line head 40. The paper discharge tray 17 is detachably provided on the device body 12. By removing the paper discharge tray 17, the line head 40 in the replacement position can be exposed, and the line head 40 can be removed and replaced. Here, when replacing the line head 40, there is a risk that the ink Q will flow down from the line head 40, but as shown in Fig. 3, a waste liquid tank 38 is located directly below the line head 40 in the replacement position. This allows the ink Q that has flowed down from the line head 40 to be received and collected in the waste liquid tank 38. For example, by forming the upper surface of the waste liquid tank 38 into a tray shape and providing a hole for guiding the ink Q from the upper surface of the waste liquid tank 38 into the waste liquid tank 38, the ink Q that has flowed down from the line head 40 can be collected in the waste liquid tank 38.
