[0008] [First Embodiment] Hereinafter, a first embodiment of the recording apparatus will be described with reference to the drawings. The recording apparatus is, for example, an inkjet printer that records by ejecting ink, which is an example of a liquid, onto a medium such as paper, fabric, vinyl sheet, plastic parts, or metal parts.

[0009] In the drawings, it is assumed that the recording apparatus 11 is placed on a horizontal plane, and the direction of gravity is indicated by the Z-axis, and the directions along the horizontal plane are indicated by the X-axis and the Y-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other. In the following description, the direction parallel to the X-axis is also referred to as the width direction X, the direction parallel to the Y-axis is also referred to as the depth direction Y, and the direction parallel to the Z-axis is also referred to as the vertical direction Z.

[0010] <Recording apparatus> As shown in FIG. 1, the recording apparatus 11 may include an operation panel 12, a reading unit 13 which is an example of a second cover, and a recording unit 14. The reading unit 13 and the operation panel 12 may be provided above the recording unit 14.

[0011] <Operation panel> The operation panel 12 is for the user to operate the recording apparatus 11. The operation panel 12 is operated by the user. The operation panel 12 may have a monitor, buttons, a touch panel, etc.

[0012] <Reading unit> The reading unit 13 is configured to read an image of a document (not shown). The reading unit 13 of the present embodiment is provided adjacent to the operation panel 12 at a position behind the operation panel 12 in the depth direction Y. The reading unit 13 may be rotatable about a hinge (not shown) or a shaft (not shown) provided behind in the depth direction Y. The reading unit 13 may be provided so as to be openable and closable with respect to the recording unit 14. The reading unit 13 may be displaceable by rotation to a reading position PR1 which is an example of a second cover position shown in FIG. 1 and a non-reading position PR2 which is an example of a second non-cover position shown in FIG. 2.

[0013] When the user performs, for example, scanning a document, they position the reading unit 13 at the reading position PR1. When the user performs, for example, maintenance on the recording unit 14, they position the reading unit 13 at the non-reading position PR2. The reading position PR1 is a position that covers the inside of the device. When the reading unit 13 is located at the reading position PR1, it is aligned with the recording unit 14 and covers a portion of the recording unit 14 from above. The non-reading position PR2 is a position that does not cover the inside of the device. When the reading unit 13 is located at the non-reading position PR2, it leaves the inside of the recording unit 14 open.

[0014] As shown in Figure 1, the reading unit 13 may have a handle portion 16 and a reading portion 17. The handle portion 16 may be a recess located at the tip of the reading unit 13. In the width direction X, the size of the handle portion 16 may be about the same as the size of the operation panel 12, or it may be larger than the operation panel 12. By placing their hand on the handle portion 16, the user can easily move the reading unit 13, which is located at the reading position PR1, to the non-reading position PR2.

[0015] The reading unit 17 is configured to read an image of a document (not shown). The reading unit 17 may be able to read a document when the reading unit 13 is at the reading position PR1. The reading unit 17 may read a transported document while it is stationary. The reading unit 17 may read a stationary document while it is moving. The reading unit 17 generates image data by reading the document.

[0016] <Recording Unit> As shown in Figure 1, the recording unit 14 is configured to record on a medium 19. The recording unit 14 may include a housing 21, a control unit 22, and a detection unit 23. The recording unit 14 may also include a liquid container 24, a supply channel 25, a recording unit 26, a maintenance unit 27, and a mounting unit 28. A waste liquid container 29, which is an example of a member to be mounted, is mounted on the mounting unit 28.

[0017] The recording unit 14 may include a first maintenance cover 31 and a second maintenance cover 32. The first maintenance cover 31 is an example of a cover and a first cover. The first maintenance cover 31 and the second maintenance cover 32 are spaced apart from each other in the width direction X. The first maintenance cover 31 and the second maintenance cover 32 are provided adjacent to the operation panel 12 so as to sandwich the operation panel 12 in the width direction X. In other words, the operation panel 12 is located between the first maintenance cover 31 and the second maintenance cover 32 in the width direction X.

[0018] The housing 21 accommodates the various components of the recording unit 14. The housing 21 may have a front surface 21f and a first upper surface 21u as shown in Figure 2. The front surface 21f is located forward in the depth direction Y. The first upper surface 21u is located upward in the vertical direction Z. The first upper surface 21u faces the operation panel 12.

[0019] The control unit 22 comprehensively controls the driving of each mechanism in the recording unit 14 and controls the various operations performed in the recording unit 14. The control unit 22 may also comprehensively control the driving of each mechanism in the recording device 11 and control the various operations performed in the recording device 11.

[0020] The control unit 22 may be configured as a circuit including α: one or more processors that perform various processes according to a computer program, β: one or more dedicated hardware circuits that perform at least some of the various processes, or γ: a combination thereof. The hardware circuit is, for example, an application-specific integrated circuit. The processor includes a CPU and memory such as RAM and ROM, and the memory stores program code or instructions configured to cause the CPU to perform the processes. Memory, or computer-readable media, includes any readable media that can be accessed by a general-purpose or dedicated computer.

[0021] The detection unit 23 can detect the opening and closing of the reading unit 13. The detection unit 23 may also detect, for example, whether or not the reading unit 13 is located at the reading position PR1. The detection unit 23 is, for example, a contact sensor. The detection unit 23 is, for example, a photoelectric sensor having a light-emitting element and a light-receiving element.

[0022] The liquid container 24 contains the liquid to be supplied to the recording unit 26. The recording unit 14 may have one or more liquid containers 24. Multiple liquid containers 24 may be arranged in a line in the width direction X. Multiple liquid containers 24 may contain different types of liquid. Different types of liquids are, for example, inks of different colors. The liquid containers 24 may be fixed to the recording unit 14. The liquid containers 24 may be refillable. The liquid containers 24 may be configured separately from the recording unit 14 and may be cartridges, packs, etc., that are detachable from the recording unit 14. In other words, the recording unit 14 may be configured without liquid containers 24.

[0023] The second maintenance cover 32 is positioned over one or more liquid containers 24. The second maintenance cover 32 is openable and closable relative to the housing 21. The second maintenance cover 32 may be opened and closed by rotation, sliding, or the like. When the second maintenance cover 32 is in the closed position shown in Figure 1, it covers the liquid containers 24. When the second maintenance cover 32 is in the open position (not shown), it exposes a portion of the liquid containers 24. By positioning the second maintenance cover 32 in the open position, it becomes possible to replenish the liquid in the liquid containers 24 or replace the liquid containers 24.

[0024] The recording device 11 may have one or more supply channels 25. The recording device 11 may have the same number of supply channels 25 as the liquid container 24. The supply channels 25 may be made of deformable tubes. The supply channels 25 are capable of supplying liquid to the recording unit 26. The upstream end of the supply channel 25 is connected to the liquid container 24, and the downstream end is connected to the recording unit 26.

[0025] As shown in Figure 2, the recording unit 26 records on the medium 19. The recording unit 26 in this embodiment is a liquid dispensing unit capable of dispensing liquid. The recording unit 26 has a nozzle surface 35 with one or more nozzles 34 opening. The recording unit 26 dispenses liquid supplied from the liquid container 24 through the nozzles 34. The recording unit 26 performs recording by dispensing the liquid onto the medium 19. The recording unit 26 may be reciprocally movable in the scanning direction. The scanning direction may be parallel to the X-axis.

[0026] As shown in Figure 1, the maintenance unit 27 performs maintenance on the recording unit 26. Maintenance may include, for example, flushing, cleaning, and wiping. The maintenance unit 27 may also forcibly discharge liquid from the nozzle 34. By discharging liquid with increased viscosity, foreign matter, air bubbles, etc., along with the liquid from the nozzle 34, the maintenance unit 27 suppresses a decrease in the performance of the nozzle 34 in discharging liquid. The maintenance unit 27 collects the discharged liquid as waste liquid. The maintenance unit 27 sends the collected waste liquid to the waste liquid container 29.

[0027] The waste liquid container 29 is capable of containing waste liquid discharged from the recording unit 26. The waste liquid container 29 also contains waste liquid collected by the maintenance unit 27. The waste liquid container 29 is detachable from the recording device 11.

[0028] As shown in Figure 2, the recording unit 14 may include a media storage section 37, a feeding section 38, a transport section 39, a support section 40, and an output tray 41. The media storage section 37 can accommodate multiple media 19 stacked on top of each other.

[0029] The feeding unit 38 feeds out the media 19 stored in the media storage unit 37 one sheet at a time. The feeding unit 38 may also include a feeding roller 43 and a separation unit 44. The feeding roller 43 rotates in contact with the media 19 stored in the media storage unit 37, thereby sending the media 19 to the separation unit 44. The separation unit 44 separates the multiple sheets of media 19 that have been fed in stacks into individual sheets.

[0030] The transport unit 39 transports the medium 19 along the transport path 46 shown by the dashed line in Figure 2. The transport unit 39 transports the medium 19 supplied by the feeding unit 38 to the discharge tray 41 located downstream in the transport direction. The transport direction is along the transport path 46.

[0031] The support section 40 supports the medium 19 being transported. The support section 40 constitutes part of the transport path 46. The support section 40 faces the recording section 26 across the transport path 46. The discharge tray 41 receives the recorded medium 19. The discharge tray 41 may be retractable. The discharge tray 41 may be reciprocally movable in the depth direction Y. In this embodiment, the discharge tray 41 is movable between a position shown in Figure 1 where it is housed in the housing 21 and a position shown in Figure 2 where it protrudes forward from the front surface 21f.

[0032] <Mounting part> As shown in Figure 3, the mounting portion 28 may be adjacent to the operation panel 12 in the width direction X. The mounting portion 28 has a mounting space on which the waste liquid container 29 can be mounted. The mounting portion 28 may include an engaging portion 48 and a pressing portion 49. In this embodiment, the engaging portion 48 opens into the rear wall surface of the mounting portion 28.

[0033] As shown in Figure 4, the mounting portion 28 may have a first spring 51. The first spring 51 biases the pressing portion 49 in the direction opposite to the first direction D1. Biasing means pushing back or pulling back an object against a force applied to it. In this embodiment, the first direction D1 is parallel to the Y-axis. In this embodiment, the first direction D1 is the same direction as the depth direction Y and is a direction toward the rear. The first spring 51 pushes the pressing portion 49 forward, which is the direction opposite to the first direction D1.

[0034] <First Maintenance Cover> As shown in Figure 3, the first maintenance cover 31 can be positioned in the uncovered position PC2. The uncovered position PC2 is an example of the first uncovered position. The uncovered position PC2 is the position where it is detached from the housing 21. The uncovered position PC2 is the position where the mounting portion 28 is not closed. When the first maintenance cover 31 is in the uncovered position PC2, it does not cover the mounting space of the mounting portion 28. By displacing the first maintenance cover 31 to the uncovered position PC2, the mounting portion 28 is exposed. When the first maintenance cover 31 is in the uncovered position PC2, the waste liquid container 29 is detachable from the mounting portion 28.

[0035] As shown in Figures 3 and 5, the first maintenance cover 31 is slidable in a first direction D1 and in the direction opposite to the first direction D1. By sliding in the first direction D1, the first maintenance cover 31 is displaced from the uncovered position PC2 shown in Figure 3 to the covered position PC1 shown in Figure 5. When the first maintenance cover 31 is in the covered position PC1, it covers the mounting space of the mounting portion 28. When the first maintenance cover 31 is in the covered position PC1, it closes the mounting portion 28 from above. The covered position PC1 is the position that closes the mounting portion 28. By sliding in the direction opposite to the first direction D1, the first maintenance cover 31 is displaced from the covered position PC1 to the uncovered position PC2.

[0036] As shown in Figures 6 and 7, the first maintenance cover 31 has an operating portion 53 and an engaging portion 54. The operating unit 53 can be moved in the first direction D1 and the direction opposite to the first direction D1 by external operation. The operating unit 53 is slidable. The operating unit 53 can move to the locked position PL1 shown in Figure 7 and the unlocked position PL2 shown in Figure 6.

[0037] The engaging portion 54 may have an arm portion 55 and a claw portion 56. The arm portion 55 may extend in a first direction D1. The arm portion 55 may be deformable to flex. The claw portion 56 is provided at the tip of the arm portion 55, protruding from the arm portion 55. In this embodiment, the engaging portion 54 has a pair of arm portions 55 and claw portions 56. The pair of claw portions 56 face outward from each other.

[0038] The engaging portion 54 is attached to the operating portion 53. The engaging portion 54 moves in conjunction with the movement of the operating portion 53. The engaging portion 54 is movable in the first direction D1 and in the direction opposite to the first direction D1. The engaging portion 54 is slidable. By moving in the first direction D1 and in the direction opposite to the first direction D1, the engaging portion 54 moves to the engaged position PE1 shown in Figure 7 and the unengaged position PE2 shown in Figure 6. The engaged position PE1 is a position in which the engaged portion 48 can engage. The unengaged position PE2 is a position in which the engaged portion 48 cannot engage.

[0039] As shown in Figure 6, when the operating part 53 is in the release position PL2, the engaging part 54 is in the disengaged position PE2. When the operating part 53 is in the release position PL2, it moves in the first direction D1 to the locked position PL1 shown in Figure 7. When the operating part 53 moves in the first direction D1, the engaging part 54 moves to the engaged position PE1. When the operating part 53 is in the locked position PL1, the engaging part 54 is in the engaged position PE1. When the operating part 53 moves in the direction opposite to the first direction D1, the engaging part 54 moves to the disengaged position PE2.

[0040] As shown in Figures 5 and 8, when the first maintenance cover 31 is in the cover position PC1 and the operating part 53 is in the locked position PL1, the engaging part 54 engages with the engaged part 48.

[0041] As shown in Figure 8, the engaging portion 54 engages with the engaged portion 48 such that a pair of claws 56 catch on it. The first maintenance cover 31 is restricted from moving forward when the engaging portion 54 engages with the engaged portion 48.

[0042] As shown in Figure 1, the first maintenance cover 31 may overlap with the reading unit 13 in the depth direction Y. The rear end of the first maintenance cover 31 located at cover position PC1 may be located behind the front end of the reading unit 13 located at reading position PR1. At least a portion of the first maintenance cover 31 may be submerged beneath the reading unit 13. In other words, the reading unit 13 may be above the first maintenance cover 31. At least a portion of the first maintenance cover 31 located at cover position PC1 may overlap with at least a portion of the reading unit 13 located at reading position PR1. When the first maintenance cover 31 is located at cover position PC1 and the reading unit 13 is located at reading position PR1, at least a portion of the operating section 53 may overlap with the reading unit 13. The reading unit 13 located at reading position PR1 may conceal at least a portion of the operating section 53. When the reading unit 13 is at reading position PR1, the operation of the operating section 53 may be restricted. When the reading unit 13 is positioned in the non-reading position PR2, the operation unit 53 becomes operational. When the reading unit 13 is positioned in the non-reading position PR2, the first maintenance cover 31 becomes detachable.

[0043] <Operation of the First Embodiment> The operation of this embodiment will now be described. As shown in Figure 8, the pressing part 49 can press the first maintenance cover 31 when it is in cover position PC1. The pressing part 49 pushes the first maintenance cover 31 forward. The force with which the pressing part 49 presses the first maintenance cover 31 is weaker than the force exerted by the engaging part 54 and the engaged part 48 to restrict the movement of the first maintenance cover 31. Therefore, when the operating part 53 is in the locked position PL1, the first maintenance cover 31 is held in cover position PC1.

[0044] When the operating part 53 is moved in the direction opposite to the first direction D1, the engagement between the engaging part 54 and the engaged part 48 is released. The first maintenance cover 31 is displaced from its cover position PC1 in the direction opposite to the first direction D1 by the force exerted by the user moving the operating part 53 in the direction opposite to the first direction D1 and the force exerted by the pressing part 49. The user can remove the first maintenance cover 31 by further displacing it in the direction opposite to the first direction D1.

[0045] <Effects of the First Embodiment> The effects of this embodiment will now be explained. (1-1) When the operating part 53 moves in the direction opposite to the first direction D1, the engaging part 54 moves to the disengaged position PE2. That is, when the operating part 53 moves in the direction opposite to the first direction D1, the engagement between the engaging part 54 and the engaged part 48 is released, and the first maintenance cover 31 becomes movable. The first maintenance cover 31 is displaced to the uncovered position PC2 by sliding in the direction opposite to the first direction D1. By aligning the direction in which the user operates the operating part 53 with the direction in which the first maintenance cover 31 slides, user operability can be improved.

[0046] (1-2) The engaging portion 54 moves in the same direction as the operating portion 53. Therefore, the force applied by the user to operate the operating portion 53 can be used directly to move the engaging portion 54. Thus, the loss of operating force can be reduced.

[0047] (1-3) The reading unit 13 located at reading position PR1 is positioned on top of the first maintenance cover 31 and overlaps with the first maintenance cover 31. Therefore, the risk of the first maintenance cover 31 coming off unintentionally can be reduced.

[0048] (1-4) The reading unit 13 located at reading position PR1 overlaps with the operating section 53 of the first maintenance cover 31 located at cover position PC1. Therefore, the risk of unintentionally moving the operating section 53 can be reduced.

[0049] (1-5) The reading unit 13 has a reading section 17. Therefore, the device can be made smaller compared to the case where the reading section 17 is provided separately. (1-6) The first maintenance cover 31 covers the waste liquid container 29. The first maintenance cover 31 has improved operability. Therefore, for example, the risk of a user having trouble removing the first maintenance cover 31 and inadvertently touching the waste liquid container 29 is reduced.

[0050] [Second Embodiment] Next, a second embodiment of the recording device will be described with reference to the figures. Note that the configuration of the mounting section and the first maintenance cover in this second embodiment differs from that of the first embodiment. However, since it is almost identical to the first embodiment in other respects, the same reference numerals are used for identical components, and redundant explanations will be omitted.

[0051] <Mounting part> As shown in Figure 9, the mounting portion 28 may include an engaged portion 48 and a pressing portion 49. In this embodiment, the engaged portion 48 protrudes forward from the rear wall surface of the mounting portion 28. The pressing portion 49 is biased in the direction opposite to the first direction D1 and is capable of pressing the first maintenance cover 31 at the cover position PC1.

[0052] <First Maintenance Cover> As shown in Figures 9 and 10, the first maintenance cover 31 is slidable in a first direction D1 and in the direction opposite to the first direction D1. By sliding in the first direction D1, the first maintenance cover 31 is displaced from the uncovered position PC2 shown in Figure 9 to the covered position PC1 shown in Figure 10. By sliding in the direction opposite to the first direction D1, the first maintenance cover 31 is displaced from the covered position PC1 to the uncovered position PC2.

[0053] The first maintenance cover 31 may have a mark 58. The mark 58 may indicate the direction of operation when removing the first maintenance cover 31. The mark 58 may be an arrow pointing towards the uncovered position PC2 when the first maintenance cover 31 is in the cover position PC1. The mark 58 may be an arrow pointing towards the unlocked position PL2 shown in Figure 11 when the operating part 53 is in the locked position PL1 shown in Figure 12.

[0054] As shown in Figures 11 and 12, the operating unit 53 can be moved in a second direction D2 and in the direction opposite to the second direction D2 by external operation. The operating unit 53 is slidable. The second direction D2 is a different direction from the first direction D1. In this embodiment, the second direction D2 is parallel to the X-axis. The second direction D2 is the same direction as the width direction X. The operating unit 53 can move to a locked position PL1 shown in Figure 12 and an unlocked position PL2 shown in Figure 11. The operating unit 53 moves to the locked position PL1 by moving in the second direction D2. The operating unit 53 moves to the unlocked position PL2 by moving in the direction opposite to the second direction D2.

[0055] The engaging portion 54 is attached to the operating portion 53. The engaging portion 54 moves in conjunction with the movement of the operating portion 53. The engaging portion 54 is movable in the second direction D2 and in the direction opposite to the second direction D2. The engaging portion 54 is slidable. By moving in the second direction D2 and in the direction opposite to the second direction D2, the engaging portion 54 moves between the engaged position PE1 shown in Figure 12 and the disengaged position PE2 shown in Figure 11.

[0056] As shown in Figure 11, when the operating part 53 is in the release position PL2, the engaging part 54 is in the disengaged position PE2. When the operating part 53 is in the release position PL2, it moves in the second direction D2 to the locked position PL1 shown in Figure 12. When the operating part 53 moves in the second direction D2, the engaging part 54 moves to the engaged position PE1. When the operating part 53 is in the locked position PL1, the engaging part 54 is in the engaged position PE1. When the operating part 53 moves in the direction opposite to the second direction D2, the engaging part 54 moves to the disengaged position PE2.

[0057] As shown in Figure 12, when the first maintenance cover 31 is in the cover position PC1 and the operating part 53 is in the locked position PL1, the engaging part 54 engages with the engaged part 48. At this time, the engaging part 54 is located behind the engaged part 48. Therefore, the forward movement of the first maintenance cover 31 is restricted.

[0058] As shown in Figure 13, when the engaging portion 54 is in the engaging position PE1, the first maintenance cover 31 moves from the uncovered position PC2 in the first direction D1, but interferes with the mounting portion 28 before it reaches the cover position PC1. Specifically, the engaging portion 54 of the first maintenance cover 31, located in the engaging position PE1, comes into contact with the engaged portion 48. Therefore, the movement of the first maintenance cover 31 in the first direction D1 is restricted before it reaches the cover position PC1.

[0059] As shown in Figure 10, the reading unit 13 may be located above the first maintenance cover 31. At least a portion of the first maintenance cover 31 located at cover position PC1 may overlap with at least a portion of the reading unit 13 located at reading position PR1. When the first maintenance cover 31 is located at cover position PC1 and the reading unit 13 is located at reading position PR1, at least a portion of the operating section 53 may overlap with the reading unit 13.

[0060] As shown in Figure 14, the reading unit 13 may have a relief groove 59. When the first maintenance cover 31 is in the cover position PC1 and the reading unit 13 is in the reading position PR1, a portion of the operating unit 53, which is in the locked position PL1, is located within the relief groove 59. However, if the operating unit 53 is not in the locked position PL1, but for example in the unlocked position PL2, the operating unit 53 will come out of the relief groove 59 and interfere with the reading unit 13. Therefore, when the first maintenance cover 31 is in the cover position PC1 and the operating unit 53 is in the unlocked position PL2, the reading unit 13 moving from the non-reading position PR2 to the reading position PR1 will interfere with the operating unit 53 before moving to the reading position PR1. When the detection unit 23 detects that the reading unit 13 is not in the reading position PR1, the control unit 22 may, for example, notify the operation panel 12 that the first maintenance cover 31 is not fixed.

[0061] <Operation of the second embodiment> The operation of this embodiment will now be described. As shown in Figure 12, the pressing portion 49 is biased by the first spring 51 and pushes the first maintenance cover 31, which is in cover position PC1, in the direction opposite to the first direction D1. The pressing portion 49 may also push the engaging portion 54 forward.

[0062] When the operating part 53, located in the locked position PL1, is moved in the direction opposite to the second direction D2, the engagement between the engaging part 54 and the engaged part 48 is released. The first maintenance cover 31 is displaced from the cover position PC1 in the direction opposite to the first direction D1 by the force of the pressing part 49. The user can remove the first maintenance cover 31 by further displacing the first maintenance cover 31 in the direction opposite to the first direction D1.

[0063] <Effects of the second embodiment> The effects of this embodiment will now be explained. (2-1) The pressing part 49 pushes the first maintenance cover 31, which is located in the cover position PC1, toward the uncovered position PC2. As a result, when the engagement between the engaging part 54 and the engaged part 48 is released, the first maintenance cover 31 moves in the opposite direction to the first direction D1. Therefore, the direction in which to remove the first maintenance cover 31 becomes clearer, thereby improving user operability.

[0064] (2-2) The pressing part 49 presses the first maintenance cover 31, making it easier to understand the direction in which to remove the first maintenance cover 31. Therefore, even if the direction in which the operating part 53 is moved and the direction in which the first maintenance cover 31 is slid are different, the risk of the user becoming confused about how to remove the first maintenance cover 31 can be reduced. Thus, the degree of freedom of the operating part 53 can be increased.

[0065] (2-3) When the engaging portion 54 is in the engaging position PE1, the engaging portion 54 interferes with the mounting portion 28. Therefore, the first maintenance cover 31 cannot be displaced to the cover position PC1. Thus, the risk of the cover being mounted in an incorrect state can be reduced.

[0066] (2-4) The detection unit 23 detects the opening and closing of the reading unit 13. Therefore, the risk of the reading unit 13 being used when it is not positioned at the reading position PR1 can be reduced. [Third Embodiment] Next, a third embodiment of the recording device will be described with reference to the figures. Note that the configuration of the mounting section and the first maintenance cover in this third embodiment differs from that of the first embodiment. However, since it is almost identical to the first embodiment in other respects, the same reference numerals are used for identical components, and redundant explanations will be omitted.

[0067] <Mounting part> As shown in Figure 15, the mounting portion 28 includes an engaging portion 48. In this embodiment, the engaging portion 48 opens into the lateral wall surface of the mounting portion 28. The engaging portion 48 may be located between the first maintenance cover 31, which is located at cover position PC1, and the operation panel 12 in the width direction X.

[0068] <First Maintenance Cover> As shown in Figure 15, the first maintenance cover 31 is slidable in a first direction D1 and in the direction opposite to the first direction D1. By sliding in the first direction D1, the first maintenance cover 31 is displaced from the uncovered position PC2, shown by the dashed line in Figure 15, to the covered position PC1. By sliding in the direction opposite to the first direction D1, the first maintenance cover 31 is displaced from the covered position PC1 to the uncovered position PC2.

[0069] The first maintenance cover 31 has an operating section 53. The operating section 53 is movable in a first direction D1 and in the direction opposite to the first direction D1 by being operated from the outside. The operating section 53 is slidable. The operating section 53 is movable between a locked position PL1 and an unlocked position PL2.

[0070] As shown in Figures 16 and 17, the first maintenance cover 31 may have an engaging portion 54, a first link 61, and a second link 62. The first link 61 connects the operating unit 53 to the second link 62. The second link 62 connects the first link 61 to the engaging unit 54. The engaging unit 54 moves in conjunction with the movement of the operating unit 53. The engaging unit 54 is movable in the second direction D2 and in the direction opposite to the second direction D2. The engaging unit 54 is slidable. By moving in the second direction D2 and in the direction opposite to the second direction D2, the engaging unit 54 moves to the engaged position PE1 shown in Figure 17 and the unengaged position PE2 shown in Figure 16.

[0071] When the operating part 53 is in the release position PL2, the engaging part 54 is in the disengaged position PE2. When the operating part 53 is in the release position PL2, it moves to the locked position PL1 by moving in the first direction D1. When the operating part 53 moves in the first direction D1, the engaging part 54 moves to the engaged position PE1. When the operating part 53 is in the locked position PL1, the engaging part 54 is in the engaged position PE1. When the operating part 53 moves in the direction opposite to the first direction D1, the engaging part 54 moves to the disengaged position PE2.

[0072] As shown in Figure 15, when the first maintenance cover 31 is in the cover position PC1 and the operating part 53 is in the locked position PL1, the engaging part 54 engages with the engaged part 48. The first maintenance cover 31 is restricted from moving forward when the engaging part 54 engages with the engaged part 48.

[0073] As shown in Figure 17, the engaging portion 54 located at the engaging position PE1 protrudes from the first maintenance cover 31. When the engaging portion 54 is located at the engaging position PE1, the first maintenance cover 31 moves from the uncovered position PC2 in the first direction D1 and interferes with the mounting portion 28 before moving to the cover position PC1. The first maintenance cover 31 may also interfere with the member through which the mounting portion 28 opens. The movement of the first maintenance cover 31 in the first direction D1 is restricted before it reaches the cover position PC1.

[0074] <Operation of the Third Embodiment> The operation of this embodiment will now be described. As shown in Figure 15, when the operating part 53 is moved in the direction opposite to the first direction D1, the engagement between the engaging part 54 and the engaged part 48 is released. The user can remove the first maintenance cover 31 by displacing it in the direction opposite to the first direction D1.

[0075] <Effects of the Third Embodiment> The effects of this embodiment will now be explained. (3-1) The engaging portion 54 moves in a direction different from the direction in which the first maintenance cover 31 slides. Therefore, even if force is applied to the first maintenance cover 31 while the engaging portion 54 is engaged with the engaged portion 48, the first maintenance cover 31 can be made difficult to move.

[0076] [Fourth Embodiment] Next, a fourth embodiment of the recording device will be described with reference to the figures. Note that the configuration of the first maintenance cover in this fourth embodiment differs from that of the first embodiment. However, since it is almost identical to the first embodiment in other respects, the same reference numerals are used for identical components, and redundant explanations will be omitted.

[0077] <First Maintenance Cover> As shown in Figures 18 and 19, the first maintenance cover 31 may have an operating part 53, an engaging part 54, and a second spring 64. In the width direction X, the operating part 53 may be located at one end and the engaging part 54 may be located at the other end. The operating part 53 is movable in a first direction D1 and in the direction opposite to the first direction D1 by being operated from the outside. The operating part 53 is movable between a locked position PL1 and an unlocked position PL2.

[0078] The engaging portion 54 is integrally formed with the operating portion 53. The engaging portion 54 moves in conjunction with the movement of the operating portion 53. The operating portion 53 and the engaging portion 54 are rotatable about an axis. Rotation refers to a rotation about an axis where the rotatable angle is less than 360 degrees. By rotating, the engaging portion 54 moves between an engaged position PE1 and an unengaged position PE2. The second spring 64 pushes the engaging portion 54, which is in the unengaged position PE2, toward the engaged position PE1.

[0079] As shown in Figure 19, when the operating part 53 is in the release position PL2, the engaging part 54 is in the disengaged position PE2. The operating part 53, in the release position PL2, moves to the locked position PL1 by moving in the first direction D1 due to the biasing force of the second spring 64. When the operating part 53 moves in the first direction D1, the engaging part 54 moves to the engaged position PE1. When the operating part 53 is in the locked position PL1, the engaging part 54 is in the engaged position PE1. When the operating part 53 moves in the direction opposite to the first direction D1, the engaging part 54 moves to the disengaged position PE2.

[0080] <Operation of the 4th Embodiment> The operation of this embodiment will now be described. As shown in Figure 19, when the operating part 53 is moved in the direction opposite to the first direction D1, the engagement between the engaging part 54 and the engaged part 48 is released. The user can remove the first maintenance cover 31 by displacing it in the direction opposite to the first direction D1.

[0081] <Effects of the 4th Embodiment> The effects of this embodiment will now be explained. (4-1) The engaging portion 54 rotates. Therefore, compared to, for example, sliding the engaging portion 54, the engaging portion 54 can be moved with less force.

[0082] [Example of changes] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0083] If the detection unit 23 detects that the reading unit 13 is not located at the reading position PR1, the control unit 22 may prohibit recording. - At least a portion of the second maintenance cover 32 in the closed position may overlap with the reading unit 13 in the reading position PR1. When the reading unit 13 is in the reading position PR1, the displacement of the second maintenance cover 32 from the closed position to the open position may be restricted. When the reading unit 13 is in the non-reading position PR2, the displacement of the second maintenance cover 32 from the closed position to the open position may be permitted.

[0084] The recording device 11 may include a second cover separate from the reading unit 13. The second cover may not include a reading unit 17. For example, the recording device 11 may include a second cover that is opened and closed when removing a jammed medium 19 during transport. The second cover may overlap at least a part of the first maintenance cover 31 or at least a part of the operation unit 53. The second cover may be located in front of the first maintenance cover 31 in the depth direction Y.

[0085] The detection unit 23 may detect the position of the operating unit 53. The detection unit 23 may also detect that the engaging unit 54 is engaged with the engaged unit 48. When the first maintenance cover 31 is in cover position PC1 and the reading unit 13 is in reading position PR1, the operating unit 53 may be positioned in a location that does not overlap with the reading unit 13.

[0086] The first maintenance cover 31 located at cover position PC1 does not have to overlap with the reading unit 13 located at reading position PR1. The first maintenance cover 31 may be displaceable between cover position PC1 and uncovered position PC2 while the reading unit 13 remains at reading position PR1.

[0087] In the third and fourth embodiments, the pressing portion 49 may press the first maintenance cover 31 in a direction opposite to the first direction D1. In the first embodiment, the mounting portion 28 may be configured without a pressing portion 49.

[0088] The recording device 11 may include multiple mounting sections 28. The recording device 11 may include a mounting portion 28 to which a liquid container 24 can be attached. The liquid container 24 may be an example of a member to be attached. The second maintenance cover 32 may be an example of a cover and a first cover. The second maintenance cover 32 may include an operating portion 53 and an engaging portion 54.

[0089] The media storage section 37 may be an example of a member to be mounted. The recording device 11 may be provided with a cover that covers the media storage section 37. Multiple members to be attached may be attached to a single attachment portion 28. For example, a liquid container 24 and a waste liquid container 29 may be attached to the attachment portion 28.

[0090] • The mounting section 28 may be capable of mounting an example of a component to be mounted, such as a toner cartridge. The toner cartridge may contain toner used for recording. • A toner box, which is an example of a component to be mounted, may be mounted in the mounting section 28. The toner box may contain the collected toner.

[0091] The recording device 11 is not limited to an inkjet printer; it may also be a laser printer, thermal printer, dot matrix printer, digital printing press, etc. The recording device may be a liquid ejection device that performs recording by spraying or ejecting liquids other than ink. The state of the liquid ejected from the liquid ejection device as minute droplets may include granular, teardrop-shaped, or thread-like forms. The liquid referred to here may be any material that can be ejected from a liquid ejection device. For example, the liquid may be any state in which a substance is in the liquid phase, and may include highly or low viscosity liquids, sols, gel water, other inorganic solvents, organic solvents, solutions, liquid resins, liquid metals, and other fluids. The liquid may include not only liquids as a state of matter, but also functional materials consisting of particles of solids such as pigments and metal particles dissolved, dispersed, or mixed in a solvent. Typical examples of liquids include inks and liquid crystals as described in the above embodiments. Here, ink refers to general water-based inks and oil-based inks, as well as various liquid compositions such as gel inks and hot-melt inks. Specific examples of liquid spraying devices include devices that spray liquids containing materials such as electrode materials and colorants in the form of dispersion or solution, used in the manufacture of liquid crystal displays, electroluminescent displays, surface-emitting displays, and color filters. Liquid spraying devices may also be devices that spray bio-organic materials used in biochip manufacturing, devices that spray liquid samples used as precision pipettes, printing devices, microdispensers, etc. Liquid spraying devices may also be devices that spray lubricating oil with pinpoint accuracy onto precision machinery such as watches and cameras, or devices that spray transparent resin liquids such as ultraviolet-curing resins onto substrates to form minute hemispherical lenses, optical lenses, etc., used in optical communication elements. Liquid spraying devices may also be devices that spray etching solutions such as acids or alkalis to etch substrates.

[0092] [Definition] As used herein, the expression "at least one" means "one or more" of the desired options. For example, as used herein, if there are two options, the expression "at least one" means "only one option" or "both of the two options." As another example, as used herein, the expression "at least one" means "only one option," "a combination of two arbitrary options," or "a combination of three or more arbitrary options" if there are three or more options.

[0093] [Note] The technical concepts and their effects that can be understood from the embodiments and modifications described above are described below.

[0094] [1] The recording device comprises a recording unit for recording on a medium, a mounting unit having a mounting space on which a member to be mounted can be mounted, and a cover that, by sliding in a first direction, is displaced from an uncovered position that does not cover the mounting space to a covered position that covers the mounting space, and by sliding in a direction opposite to the first direction, is displaced from the covered position to the uncovered position, wherein the cover has an operating unit that can move in the first direction and in the direction opposite to the first direction by being operated from the outside, and an engaging unit that can engage with an engaging portion provided on the mounting unit, wherein when the operating unit moves in the first direction, the engaging unit moves to an engaging position that can engage with the engaging portion, and when the operating unit moves in the direction opposite to the first direction, it moves to an unengaged position that cannot engage with the engaging portion.

[0095] In this configuration, the engaging portion moves to the disengaged position when the operating portion moves in the direction opposite to the first direction. That is, when the operating portion moves in the direction opposite to the first direction, the engagement between the engaging portion and the engaged portion is released, and the cover becomes movable. The cover is displaced to the uncovered position by sliding in the direction opposite to the first direction. By aligning the direction in which the user operates the operating portion with the direction in which the cover slides, user operability can be improved.

[0096] [2] The recording device comprises a recording unit for recording on a medium, a mounting unit having a mounting space on which a member to be mounted can be mounted, and a cover that, by sliding in a first direction, is displaced from an uncovered position that does not cover the mounting space to a covered position that covers the mounting space, and by sliding in a direction opposite to the first direction, is displaced from the covered position to the uncovered position, wherein the cover has an operating unit that can move to a locked position and an unlocked position by being operated from the outside, and an engaging unit that can engage with an engaging portion provided on the mounting unit, wherein the engaging unit is in an engaging position that can engage with the engaging portion when the operating unit is in the locked position, and is in an unengaged position that cannot engage with the engaging portion when the operating unit is in the unlocked position, and the mounting unit has a pressing unit that is biased in a direction opposite to the first direction and can press the cover when it is in the cover position.

[0097] In this configuration, the pressing part pushes the cover, which is in the covered position, toward the uncovered position. Therefore, when the engagement between the engaging part and the engaged part is released, the cover moves in the opposite direction to the first direction. Thus, the direction in which to remove the cover becomes clearer, improving user operability.

[0098] [3] In the recording device described in [2] above, the operating unit may move to the locked position by moving in a second direction different from the first direction, and move to the unlocked position by moving in the direction opposite to the second direction.

[0099] With this configuration, the direction in which the cover is removed is made clear because the pressing part presses against the cover. Therefore, even if the direction in which the operating part is moved and the direction in which the cover is slid are different, the risk of the user getting confused about how to remove the cover is reduced. Consequently, the degree of freedom of the operating part can be increased.

[0100] [4] In the recording device described in [1] or [2] above, the engaging portion may move between the engaged position and the disengaged position by moving in the first direction and in the direction opposite to the first direction.

[0101] In this configuration, the engaging part moves in the same direction as the operating part. Therefore, the force the user applies to operating the operating part can be directly used to move the engaging part. Consequently, the loss of operating force can be reduced.

[0102] [5] In the recording device described in [1] or [2] above, the engaging portion may move between the engaged position and the disengaged position by moving in a second direction different from the first direction and in a direction opposite to the second direction.

[0103] With this configuration, the engaging portion moves in a direction different from the direction in which the cover slides. Therefore, even if force is applied to the cover while the engaging portion is engaged with the engaged portion, the cover can be made less likely to move.

[0104] [6] In the recording device described in [1] or [2] above, the engaging portion may move between the engaged position and the disengaged position by rotation. In this configuration, the engaging part rotates. Therefore, compared to, for example, sliding the engaging part, it can be moved with less force.

[0105] [7] In the recording device described in [1] or [2] above, the cover, which moves from the non-covered position in the first direction while the engaging portion is in the engaging position, may interfere with the mounting portion before moving to the cover position.

[0106] In this configuration, when the engaging portion is in the engaged position, it interferes with the mounting portion. Therefore, the cover cannot be displaced to the cover position. Consequently, the risk of the cover being mounted incorrectly can be reduced.

[0107] [8] In any one of the recording devices described in [1] to [7] above, if the cover is designated as a first cover, the cover position as a first cover position, and the uncovered position as a first uncovered position, the device further comprises a second cover, the second cover being displaceable between a second cover position that covers the inside of the device and a second uncovered position that does not cover the inside of the device, at least a portion of the first cover located in the first cover position overlaps with at least a portion of the second cover located in the second cover position, and the second cover may be located above the first cover.

[0108] In this configuration, the second cover, located in the second cover position, is positioned above the first cover and overlaps it. Therefore, the risk of the first cover accidentally coming off is reduced.

[0109] [9] In the recording device described in [8] above, when the first cover is in the first cover position and the second cover is in the second cover position, at least a part of the operating section may overlap with the second cover.

[0110] In this configuration, the second cover, located in the second cover position, overlaps the operating section of the first cover, which is located in the first cover position. Therefore, the risk of unintentionally moving the operating section can be reduced.

[0111]

[10] In the recording device described in [8] or [9] above, when the first cover is in the first cover position and the operating unit is in the release position, the second cover, which moves from the second uncovered position to the second cover position, may interfere with the operating unit before moving to the second cover position.

[0112] With this configuration, when the operating part is in the release position, the second cover interferes with the operating part; therefore, the second cover cannot be displaced to the second cover position. Thus, the risk of the operating part being used while in the release position is reduced.

[0113]

[11] Any one of the recording devices described in [8] to

[10] above may be equipped with a detection unit capable of detecting the opening and closing of the second cover. With this configuration, the detection unit detects the opening and closing of the second cover. Therefore, the risk of the device being used when the second cover is not in the second cover position can be reduced.

[0114]

[12] In any one of the recording devices described in [8] to

[11] above, the second cover may have a reading unit for reading an image of the original document. In this configuration, the second cover has a reading unit. Therefore, the device can be made smaller compared to a case where the reading unit is provided separately.

[0115]

[13] Any one of the recording devices described in [1] to

[12] above is equipped with a maintenance unit for performing maintenance on the recording unit, the recording unit being a liquid discharge unit capable of discharging liquid, and the mounted member being a waste liquid container for storing waste liquid collected by the maintenance unit.

[0116] In this configuration, the cover encloses the waste liquid container. The cover offers improved operability. Therefore, for example, it reduces the risk of a user having trouble removing the cover and inadvertently touching the waste liquid container. [Explanation of Symbols]
