Description

[Technical Field]

[0001] The present invention relates to a waste liquid container and a recording device. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as shown in Patent Document 1, a waste liquid pack is known that is configured to be detachable from a printer and that stores waste liquid discharged from the printer. The waste liquid pack includes a container, an opening communicating with the container, a sealing member that seals the opening, and a biasing member that biases the sealing member in the direction that closes the opening. When the waste liquid pack is attached to the printer, the printer's outlet pushes the sealing member into the waste liquid pack, allowing waste liquid discharged from the printer to be stored in the waste liquid pack. Meanwhile, when the waste liquid pack is removed from the outlet, the biasing force causes the sealing member to close the opening. This prevents waste liquid from leaking from the waste liquid pack.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-199012 Summary of the Invention [Problem to be solved by the invention]

[0004] In the waste liquid pack, when the waste liquid pack is attached to the printer, the inside of the container is in communication with the atmosphere, so it is possible to anticipate evaporation of the contained waste liquid. However, when the waste liquid pack is installed in the printer, leakage of waste liquid from the opening is considered, and it is difficult to make the opening large enough to allow communication with the atmosphere when the waste liquid pack is installed. As a result, the amount of waste liquid that evaporates from the opening is limited, resulting in low evaporation efficiency. [Means for solving the problem]

[0005] The waste liquid container is configured to be attachable to and detachable from a device having a discharge section that discharges waste liquid, and is capable of containing waste liquid discharged from the discharge section.The waste liquid container comprises a housing that contains the waste liquid and has an opening formed on its top surface, a receiving section that receives the waste liquid discharged from the discharge section, and a lid that can open and close the opening, and when the waste liquid container is attached to the device, the lid takes an open state that opens the opening, and when the waste liquid container is removed from the device, the lid takes a closed state that closes the opening.

[0006] The recording apparatus includes a main body, a recording head that performs recording by ejecting liquid onto a medium, a discharge unit that discharges waste liquid generated inside the main body, and the waste liquid container. [Brief explanation of the drawings]

[0008] 1. First embodiment First, we will explain the configuration of the recording device 10. The recording device 10 of this embodiment is a serial inkjet printer that performs recording by ejecting ink as a liquid onto a medium P (for example, paper). 1 and 2 are perspective views showing the configuration of a recording apparatus 10. FIG. When the recording device 10 is installed on an XY plane (horizontal plane) parallel to the X and Y axes, the direction along the Z axis is the up-down direction, the +Z direction is the upward direction, and the -Z direction is the downward direction. The direction along the Y axis is the front-to-back direction, with the +Y direction side being the forward direction (front side) and the -Y direction side being the backward direction (rear side). The direction along the X axis is the left-to-right direction (width direction), with the +X direction side being the leftward direction and the -X direction side being the rightward direction.

[0009] 1 and 2, the recording device 10 includes a device main body 12. The device main body 12 includes a substantially rectangular parallelepiped housing 13 and a document reading device 14 disposed on the housing 13. The document reading device 14 includes a horizontal document placement surface 15 made of transparent glass or the like on which a document to be read is placed, and a document cover 16 that can cover the document placement surface 15. The document cover 16 is provided so as to be able to open and close about a rotation shaft (not shown) that extends in a direction along the X-axis along the width direction, between a closed state (FIG. 1) in which the document placement surface 15 is covered from above, and an open state (FIG. 2) in which the document cover 16 opens from the closed state to expose the upper area of ​​the document placement surface 15.

[0010] On the outer surface of the housing 13, a discharge port 18 for discharging the medium P from the inside is provided at the bottom of the front surface 17, which is the front of the device main body 12. Inside the discharge port 18, a stacker 19 is provided for supporting the medium P in a placed state as it is discharged from inside the housing 13 toward the front side.

[0011] An operation unit 20 that is operated by the user of the recording device 10 is provided at the top of the front surface 17 of the housing 13. The operation unit 20 is a horizontally long panel whose longitudinal direction is the width direction along the X axis. The operation unit 20 is provided with a power button 21 that is operated to turn the recording device 10 on or off, and operation buttons 22 that are operated to input various types of operation information. In addition, a liquid crystal display 23 that can display the operating status of the recording device 10 is provided. The liquid crystal display 23 may be a touch panel.

[0012] An ink supply unit 25 is provided on the front surface 17 of the housing 13. The ink supply unit 25 supplies ink to the recording head 32 (FIG. 3). The ink supply unit 25 includes a plurality of ink tanks 26 and the like. The ink tanks 26 are containers that can store ink.

[0013] Next, the internal configuration of the recording device 10 will be described. As shown in FIG. 3, the recording apparatus 10 includes a recording head 32 and a carriage 30 on which the recording head 32 is mounted. The carriage 30 is supported by a guide rail 33 extending in the direction along the X axis, and is configured to be reciprocable in the direction along the X axis by a drive mechanism (not shown). A platen 34 that supports the transported medium P is disposed below the recording head 32. The platen 34 is plate-shaped. The recording head 32 has a plurality of nozzles and ejects ink as droplets onto the medium P supported by the platen 34. The recording device 10 includes a transport mechanism that transports the medium P from a paper feed unit (not shown) via a platen 34 toward the discharge port 18. Images, documents, etc. are recorded on the medium P by alternately performing a recording operation in which the recording head 32 ejects droplets to perform one pass of recording while the carriage 30 moves along the X axis, and a transport operation in which the medium P is transported to the next recording position. In this embodiment, the ink supply unit 25 and the ink tank 26 are of an off-carriage type, in which they are disposed at a position separate from the carriage 30, but the ink supply unit 25 and the ink tank 26 may also be of an on-carriage type, in which they are detachably mounted on the carriage 30. Furthermore, the recording device 10 is not limited to a serial type, and may be of a line type, in which the recording head 32 is a long line head disposed across the entire maximum width of the medium P and can eject droplets simultaneously across the entire width of the medium P.

[0014] The recording device 10 further includes a maintenance unit 40. The maintenance unit 40 performs maintenance to keep the recording head 32 in a normal state. For example, the maintenance unit 40 forcibly discharges ink and air from the recording head 32 (cleaning operation).

[0015] The maintenance unit 40 includes a cap 41. When the recording device 10 is not performing a recording operation, the carriage 30 is located at a home position that is outside the recording area during the recording operation.

[0016] The cap 41 is a box-shaped member with a bottom, and is located at the home position. The cap 41 can be moved in the direction along the Z axis by an elevation mechanism. When the cap 41 is elevated, it is pressed against the underside of the recording head 32. This causes the cap 41 to form a closed space that covers the nozzles formed on the underside of the recording head 32. This closed space can prevent the ink in the nozzles of the recording head 32 from drying out.

[0017] The cap 41 is connected to a suction pump via a suction tube. The suction pump is driven in a closed space state to suck ink and air from inside the recording head 32 via the suction tube. This sucks out deteriorated ink (ink that has dried and thickened) from inside the recording head 32, and maintains (restores) the recording head 32 in a normal state.

[0018] In addition, in order to keep the recording head 32 in a normal state, the maintenance unit 40 periodically performs a flushing operation in which ink is forcibly ejected from the recording head 32 toward the cap 41 to expel deteriorated ink from the recording head 32.

[0019] Ink (wastewater) discharged from the recording head 32 during maintenance such as cleaning and flushing is treated as waste liquid. Waste liquid is also generated during so-called borderless printing. Specifically, during recording by the recording head 32, ink (waste liquid) ejected from the recording head 32 to the outside of the edge of the medium P becomes waste liquid. As described above, waste liquid generated inside the apparatus main body 12 is collected by the waste liquid collection unit 50. The waste liquid collected by the waste liquid collection unit 50 is then discharged into the waste liquid container 60, and the discharged waste liquid is stored in the waste liquid container 60. Because waste liquid generated during cleaning operations, flushing operations, borderless printing, and the like is stored in the waste liquid container 60, contamination inside the apparatus main body 12 can be suppressed.

[0020] The recording device 10 also includes a control unit that controls each driving unit, such as the recording head 32 and maintenance unit 40. The control unit includes a CPU, memory, control circuit, I / F (interface), etc. The CPU is an arithmetic processing unit. The memory is a storage device that ensures an area for storing CPU programs or a working area, and includes memory elements such as RAM and EEPROM. When recording data, etc. is obtained from an external device such as an information processing terminal via the I / F, the CPU controls each driving unit, etc.

[0021] Next, the configuration of the waste liquid recovery section 50 will be described. As shown in Figure 4, a waste liquid collection unit 50 is disposed below the platen 34. The waste liquid collection unit 50 is plate-shaped and large enough to support the entire platen 34. The platen 34 is provided with a plurality of through-holes 35. The through-holes 35 are holes that penetrate in the vertical direction and are holes that guide waste liquid (waste liquid) that is discarded outside the edge of the medium P during borderless printing to the waste liquid collection unit 50 disposed below.

[0022] 5, the waste liquid recovery unit 50 includes a receiving portion 51 that receives the waste liquid guided from the platen 34. The receiving portion 51 has a flat portion 51a having a flat surface and a wall portion 51b that defines the flat portion 51a, and receives the waste liquid guided from the platen 34 in the flat portion 51a defined by the wall portion 51b.

[0023] Furthermore, the waste liquid collection unit 50 has a recessed portion 52 recessed below the plane of the flat portion 51a. The recessed portion 52 is disposed in the center of the waste liquid collection unit 50 in the direction along the X-axis. This allows the waste liquid from the flat portion 51a to easily flow into the recessed portion 52. The waste liquid collection unit 50 collects waste liquid generated during borderless printing as waste liquid. In addition, waste liquid discharged during cleaning by the maintenance unit 40 and waste liquid discharged during flushing can also be collected via the cap 41.

[0024] The waste liquid collection unit 50 has a discharge unit 55 that discharges the collected waste liquid into the waste liquid container 60. The discharge unit 55 of this embodiment protrudes in the -Y direction and is provided with a groove 56 through which the waste liquid flows. The groove 56 has an elongated depression along the Y axis. The outer shape of the discharge unit 55 gradually decreases in dimension along the X axis in the -Y direction. Furthermore, the outer shape of the discharge unit 55 gradually decreases in dimension along the Z axis in the -Y direction. In other words, the outer shape of the discharge unit 55 forms a pointed shape in the -Y direction. The discharge unit 55 protrudes in the -Y direction from the bottom of the recess 52. Furthermore, the groove 56 is inclined downward in the -Y direction. This allows the waste liquid to easily flow from the recess 52 toward the waste liquid container 60. In this embodiment, the discharge section 55 is positioned at the center of the drainage collection section 50 in the direction along the X axis, but it may also be positioned on the +X side or the -X side of the drainage collection section 50.

[0025] As shown in FIG. 6 , the tip of the discharge unit 55 in the −Y direction is inserted into the waste liquid container 60 via the receiving unit 64. The receiving unit 64 has an opening provided in the housing 62 of the waste liquid container 60 and receives the waste liquid discharged from the discharge unit 55. The receiving unit 64 is provided on a first surface 101 of the housing 62. In this embodiment, the first surface 101 is the end surface of the housing 62 in the +Y direction when the waste liquid container 60 is attached to the device main body 12. In this embodiment, an absorber 63 that absorbs the waste liquid is laid inside the housing 62 of the waste liquid container 60. The absorber 63 is, for example, a nonwoven fabric or a sponge material. Therefore, in this embodiment, the waste liquid collected by the waste liquid collection unit 50 is introduced into the housing 62 via the receiving unit 64, and the introduced waste liquid is absorbed and held by the absorber 63. Holding the waste liquid more effectively prevents the waste liquid from dripping. Furthermore, since the outer shape of the discharge portion 55 is pointed in the -Y direction, it can be easily inserted into the drained liquid receptacle 60. By inserting the discharge portion 55 into the drained liquid receptacle 60 via the receiving portion 64, the drained liquid can be reliably poured into the drained liquid receptacle 60. Furthermore, the groove portion 56 of the discharge portion 55 and the absorber 63 easily come into contact with each other. As a result, the drained liquid discharged through the groove portion 56 of the discharge portion 55 is absorbed by the absorber 63. Furthermore, leakage of the drained liquid from the receiving portion 64 can be suppressed.

[0026] Next, the configuration of the waste fluid container 60 will be described. The waste liquid container 60 collects waste liquid generated inside the device body 12 via the waste liquid collection section 50 . The drained liquid container 60 is detachable from the recording device 10 (device body 12) which is a device equipped with a discharge unit 55. Because there is a limit to the amount of drained liquid that can be stored in the drained liquid container 60, it is necessary to replace it with a new drained liquid container 60. Therefore, when the drained liquid in the drained liquid container 60 reaches a specified storage amount, the drained liquid container 60 in use is removed from the device body 12 and a new drained liquid container 60 is attached to the device body 12. In this case, the user removes the rear cover 11 attached to the rear side of the device body 12 from the device body 12, as shown in FIG. 7.

[0027] 8, the waste liquid receptacle 60 is exposed. The waste liquid receptacle 60 is disposed while being supported by the bottom plate portion 29. The waste liquid receptacle 60 has a grip portion 61 for being held with fingers. The grip portion 61 is provided on a second surface 102, which is the surface opposite to the first surface 101 on which the receiving portion 64 of the waste liquid receptacle 60 is disposed. In this embodiment, the second surface 102 is the end surface in the -Y direction of the housing 62 when the waste liquid receptacle 60 is attached to the device main body 12. The user can remove the waste liquid container 60 from the device main body 12 by pulling in the −Y direction with the fingers hooked on the grip portion 61. When attaching the drainage liquid receptacle 60 to the device main body 12, the drainage liquid receptacle 60 is inserted into the device main body 12 with the receiving portion 64 facing in the +Y direction, and the drainage liquid receptacle 60 is set on the bottom plate portion 29. Thereafter, the user attaches the rear cover 11 to the rear side of the device main body 12. By providing the grip portion 61 on the opposite side of the receiving portion 64, it becomes easy to attach and detach the receiving portion 64 to and from the discharge portion 55 while holding the grip portion 61.

[0028] The first surface 101 and the second surface 102 are surfaces that intersect with the attachment / detachment direction of the waste liquid container 60 relative to the device main body 12. In this embodiment, the attachment / detachment direction is along the Y axis, the mounting direction is the +Y direction, and the removal direction is the -Y direction. The first surface 101 on which the receiving portion 64 is arranged faces the discharge portion 55 in the attachment / detachment direction, making it easy to connect the receiving portion 64 to the discharge portion 55.

[0029] As described above, when the amount of drained liquid in the drained liquid container 60 reaches a specified amount, it is necessary to replace it with a new drained liquid container 60. However, if the replacement interval for the drained liquid container 60 is relatively short, the user will have to spend time on the replacement work, which will reduce user satisfaction. Therefore, it is conceivable to increase the size of the drained liquid container 60 to increase the capacity of the drained liquid that can be stored. However, if the size of the drained liquid container 60 is increased, the size of the recording device 10 will also increase. In this embodiment, the waste liquid contained in the waste liquid container 60 is efficiently evaporated without increasing the size of the waste liquid container 60, thereby increasing the apparent storage capacity of the waste liquid in the waste liquid container 60 and enabling the replacement period of the waste liquid container 60 to be extended. The detailed configuration of the waste fluid container 60 will be described below.

[0030] 9A and 9B, the waste liquid container 60 includes a housing 62 made of a resin material. The housing 62 is a container capable of storing waste liquid. The housing 62 has a substantially rectangular parallelepiped shape. In this embodiment, the housing 62 has a longer dimension along the X axis than the dimension along the Y axis, and a shorter dimension along the Z axis than the dimension along the X axis. A receiving section 64 that connects to the discharge section 55 is disposed in a part of the housing 62 of the waste liquid container 60. The receiving section 64 is provided on a first surface 101, which is the end surface in the +Y direction of the housing 62. The receiving section 64 in this embodiment has an opening (through-hole), and the waste liquid collected in the waste liquid collection section 50 is introduced into the housing 62 through the receiving section 64. Furthermore, the receiving portion 64 in this embodiment is disposed in the center in the direction along the X-axis of the first surface 101. However, the receiving portion 64 does not have to be disposed in the center in the direction along the X-axis of the first surface 101.

[0031] An opening 65 is formed on an upper surface 62a in the +Z direction of the housing 62. The opening 65 is an opening provided in the housing 62, and is a portion that exposes the inside of the housing 62. In addition, a lid 66 that can open and close the opening 65 is provided. The opening 65 is disposed closer to the receiving portion 64 than the gripping portion 61 of the housing 62. The opening 65 in this embodiment is formed from the end of the housing 62 in the +Y direction all the way along the X axis of the housing 62.

[0032] The lid portion 66 is a plate-shaped member and is disposed along the upper surface 62a. The lid portion 66 has the same shape and size as the opening 65 in a plan view. When the lid portion 66 is in the open state, the opening 65 is almost entirely open, and the absorber 63 inside the housing 62 is exposed. On the other hand, when the lid portion 66 is in the closed state, the opening 65 is entirely closed. Note that the lid portion 66 may be larger than the opening 65 as long as it covers the opening 65.

[0033] In this embodiment, when the waste liquid container 60 is attached to the device main body 12, the lid portion 66 takes an open state that opens the opening 65, and when the waste liquid container 60 is removed from the device main body 12, the lid portion 66 takes a closed state that blocks the opening 65. In the operation of attaching the waste liquid container 60 to the device main body 12, the timing at which the lid portion 66 is opened and closed may be arbitrary.

[0034] The opening 65 is provided at a position different from the receiving portion 64. Because the receiving portion 64 is the portion that connects to the discharge portion 55, it is necessary to consider leakage of the drained liquid, and it is difficult to make the opening portion of the receiving portion 64 larger. On the other hand, because the opening 65 is located on the upper surface 62a of the housing 62, it is possible to form the opening 65 relatively large. Therefore, while the lid portion 66 is in the open state and the opening 65 is open, the contact area between the inside of the housing 62 and the atmosphere is increased, which promotes evaporation of the drained liquid contained in the housing 62 and enables the drained liquid to dry more quickly. Accelerated drying of the waste liquid in the housing 62 increases the apparent storage capacity of the waste liquid receptacle 60, thereby extending the replacement interval of the waste liquid receptacle 60. In addition, the waste liquid receptacle 60 can be prevented from becoming large. Furthermore, when the waste liquid container 60 is removed from the device body 12, the lid 66 is closed and the opening 65 is blocked, so that leakage of the waste liquid inside the housing 62 can be suppressed.

[0035] The lid 66 is biased to the closed state. Specifically, the waste liquid container 60 includes a biasing member, and the lid 66 is maintained in the closed state by the biasing force of the biasing member. For example, one end of a coil spring serving as the biasing member is connected to the +Y direction end of the housing 62, and the other end is connected to the lid 66. When the lid 66 is in the closed state, the coil spring is in a compressed state, and when the lid 66 is in the open state, the coil spring is in an expanded state. Because the lid 66 is biased to the closed state, it is possible to prevent the lid 66 from opening unintentionally when the device is removed from the device main body 12. Furthermore, because the lid 66 closes by the biasing force, a drive mechanism for closing the lid 66 is not required, and the opening and closing mechanism for the lid 66 can be configured with a simple structure.

[0036] Furthermore, the lid portion 66 is displaced along the attachment / detachment direction of the effluent container 60. Specifically, when the effluent container 60 is moved in the attachment direction (+Y direction) relative to the device main body 12, the lid portion 66 is displaced to the open state. On the other hand, when the effluent container 60 is moved in the removal direction (-Y direction) relative to the device main body 12, the lid portion 66 is displaced to the closed state. A displacement mechanism of the lid portion 66 corresponding to the attachment / detachment direction of the effluent container 60 can be configured by installing the above-mentioned biasing member. By displacing the lid portion 66 along the attachment / detachment direction of the effluent container 60, only a small space is required to displace the lid portion 66 in the height direction intersecting the attachment / detachment direction of the housing 62, and the size of the effluent container 60 can be reduced. Furthermore, by displacing the lid portion 66 along the attachment / detachment direction of the effluent container 60, it is easy to link the attachment / detachment operation of the effluent container 60 with the opening / closing operation.

[0037] The lid portion 66 is displaceable along the top surface 62a. More specifically, the lid portion 66 is displaceable between an open state and a closed state in a direction along the Y axis of the top surface 62a. This reduces the space required to displace the lid portion 66 in the height direction of the housing 62, thereby reducing the size of the housing 62 in the height direction. Furthermore, the space required to displace the lid portion 66 in the recording device 10 is also reduced, thereby reducing the size of the recording device 10 in the height direction.

[0038] When viewed from above in the open state, lid portion 66 is displaced within the area of ​​top surface 62a. That is, lid portion 66, which is displaced between the closed state and the open state, does not protrude from housing 62 when viewed from above. Therefore, there is no need to ensure a displacement area for lid portion 66 outside housing 62 when viewed from above.

[0039] Next, the mechanism for opening and closing the lid 66 of the waste liquid container 60 relative to the device main body 12 will be described. 10A, the lid portion 66 has an abutment portion 67. The abutment portion 67 is a protrusion that protrudes in the +Z direction. In this embodiment, the abutment portion 67 is the end portion of the lid portion 66 in the +Y direction, and is provided in the center in the direction along the X axis (FIG. 9A). Furthermore, a contact portion 80 is disposed within the device main body 12. The contact portion 80 is a protrusion that contacts the contact portion 67 during the attachment operation of the waste liquid container 60. The -Z direction end of the contact portion 80 is located further in the +Z direction than the -Z direction end of the contact portion 67. In other words, the contact portion 80 contacts only the contact portion 67 of the waste liquid container 60 that moves in the attachment / detachment direction.

[0040] As shown in FIG. 10B , when the waste liquid receptacle 60 is moved in the mounting direction (+Y direction) and mounted on the device main body 12 (discharge unit 55), the abutting portion 67 and the abutted portion 80 come into contact with each other. Then, by further moving in the mounting direction while in abutting contact, the lid portion 66 moves in the −Y direction relative to the housing 62 against the biasing force and is displaced to the open state. This opens the opening 65, exposing the inside of the housing 62 and promoting drying of the waste liquid contained in the waste liquid receptacle 60. During the process of mounting the waste liquid receptacle 60 on the device main body 12, the abutting portion 67 and the abutted portion 80 come into contact with each other, thereby eliminating the need for a drive mechanism for opening the lid portion 66 and enabling a simple configuration for realizing an opening / closing mechanism for the lid portion 66.

[0041] On the other hand, when the waste liquid container 60 is moved in the removal direction (-Y direction), the lid part 66 moves in the +Y direction relative to the housing 62 due to the biasing force, and when the abutting part 67 and the abutted part 80 separate from each other, the lid part 66 is displaced to the closed state. Therefore, the opening 65 is closed, and leakage of the waste liquid from the opening 65 can be suppressed. In addition, when the waste liquid container 60 is attached to the device main body 12, the waste liquid container 60 is in a state of being repelled in the −Y direction by the biasing force in the +Y direction by the biasing member provided on the lid portion 66. For this reason, a protrusion 29a protruding in the +Z direction is formed on the bottom plate portion 29. In a state in which the waste liquid container 60 is attached to a specified position on the device main body 12, the protrusion 29a is disposed at a position that abuts the −Y direction end of the waste liquid container 60. As a result, in the attached state of the waste liquid container 60, movement of the waste liquid container 60 in the −Y direction is restricted, and the attached state of the waste liquid container 60 can be maintained. Furthermore, when the waste liquid container 60 is to be removed from the device main body 12, the waste liquid container 60 can be easily removed by lifting the waste liquid container 60 so as to climb over the protrusion 29a.

[0042] As described above, according to this embodiment, the opening 65 is provided at a position separate from the receiving portion 64, and the opening 65 can be formed large when the waste liquid receptacle 60 is attached. This promotes drying of the waste liquid, and increases the apparent capacity of the waste liquid receptacle 60 to store the waste liquid without increasing the size of the waste liquid receptacle 60. This also makes it possible to extend the replacement interval of the waste liquid receptacle 60. In this embodiment, the time to replace the waste liquid container 60 is determined, for example, by the cumulative amount of ink ejected from the recording head 32 during a cleaning operation or a flushing operation. Here, the cumulative amount of ink is reduced by the amount of ink that evaporates (dries) at predetermined time intervals, for example. When the cumulative amount of ink reaches a specified amount, a message is displayed on the liquid crystal display 23 indicating that the waste liquid container 60 needs to be replaced. Thereafter, the user removes the waste liquid container 60 and attaches a new waste liquid container 60. When the new waste liquid container 60 is attached, the cumulative amount of ink ejected from the recording head 32 is reset.

[0043] 2. Second embodiment Next, a second embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted.

[0044] 11A and 11B, the waste liquid container 60A includes a housing 62 capable of storing waste liquid. The receiving portion 64 is provided on a first surface 101, which is the end surface of the housing 62 in the +Y direction.

[0045] A plurality of openings 121 are formed in the upper surface 62a of the housing 62 in the +Z direction. The openings 121 are openings provided in the housing 62, and are portions through which the inside of the housing 62 is exposed. The openings 121 in this embodiment are slit-shaped openings extending along the X-axis. A plurality of openings 121 are arranged from the +Y-direction end of the upper surface 62a toward the -Y-direction. The openings 121 are arranged at regular intervals in the direction along the Y-axis.

[0046] Also provided is a lid portion 122 that can open and close the multiple openings 121. The lid portion 122 is a plate-shaped member. Slits 122a are formed in the lid portion 122 in areas that correspond to the multiple openings 121 when the lid portion 122 is in the open state. The slits 122a are through holes that extend along the X-axis. A plurality of slits 122a are arranged from the +Y-direction end of the lid portion 122 toward the -Y-direction. Each slit 122a has the same shape and size as each opening 121. The number of slits 122a is the same as the number of openings 121. The slits 122a are arranged at regular intervals in a direction along the Y-axis.

[0047] When the lid portion 122 is in the closed state, the slit 122a is located between adjacent openings 121. When the waste liquid container 60A is attached to the device body 12, the slit 122a is located in an area corresponding to the opening 121, and the lid portion 122 is in the open state. This exposes the absorber 63 inside the housing 62, and the drying of the waste liquid inside the housing 62 can be promoted. On the other hand, when the waste liquid container 60A is removed from the device body 12, the openings 121 are closed by the areas of the cover 122 other than the slits 122a, and the cover 122 is in a closed state. This makes it possible to prevent the waste liquid from leaking from inside the housing 62.

[0048] The cover 122 is biased to the closed position. The biasing mechanism for the cover 122 is the same as that in the first embodiment.

[0049] The lid portion 122 is displaced along the attachment / detachment direction of the waste liquid container 60A. Specifically, when the waste liquid container 60A is moved in the attachment direction (+Y direction) relative to the device body 12, the lid portion 122 is displaced to the open state. On the other hand, when the waste liquid container 60A is moved in the removal direction (-Y direction) relative to the device body 12, the lid portion 122 is displaced to the closed state. The lid portion 122 is also displaced along the upper surface 62a. Furthermore, the lid portion 122 is displaced within the area of ​​the upper surface 62a when viewed from above in the open state.

[0050] Next, the mechanism for opening and closing the lid 122 of the waste liquid container 60A relative to the device main body 12 will be described. The lid portion 122 includes an abutment portion 123. The abutment portion 123 is a protrusion that protrudes in the +Z direction. In this embodiment, the abutment portion 123 is an end portion of the lid portion 122 in the +Y direction, and is provided in the center in the direction along the X axis. Furthermore, a contact portion 124 is disposed inside the device main body 12. The contact portion 124 is a protrusion that contacts the contact portion 123 during the attachment operation of the waste liquid container 60A. The -Z direction end of the contact portion 124 is located further in the +Z direction than the -Z direction end of the contact portion 123. In other words, the contact portion 124 contacts only the contact portion 123 of the waste liquid container 60A that moves in the attachment / detachment direction.

[0051] 11B, when the waste liquid container 60A is moved in the mounting direction (+Y direction) and mounted to the device main body 12 (discharge unit 55), the abutting portion 123 and the abutted portion 124 come into contact with each other. Then, by further moving in the mounting direction while in contact, the lid portion 122 moves in the -Y direction relative to the housing 62 against the biasing force and is displaced to the open state. As a result, the opening 121 is opened to expose the inside of the housing 62, which can promote drying of the waste liquid contained in the waste liquid container 60A.

[0052] 11A, when the waste liquid container 60A is moved in the removal direction (-Y direction), the lid portion 122 moves in the +Y direction relative to the housing 62 due to the biasing force, and when the abutting portion 123 and the abutted portion 124 separate from each other, the lid portion 122 is displaced to the closed state. Therefore, the opening 121 is closed, and leakage of the waste liquid from the opening 121 can be suppressed.

[0053] As described above, according to this embodiment, the plurality of openings 121 can be opened and closed with a short movement distance of the lid portion 122, and therefore the opening area of ​​the openings 121 can be effectively increased.

[0054] 3. Third embodiment Next, a third embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted.

[0055] 12A and 12B, the waste liquid container 60B includes a housing 62 capable of storing waste liquid. The receiving portion 64 is provided on a first surface 101, which is the end surface of the housing 62 in the +Y direction.

[0056] An opening 131 is formed in an upper surface 62a in the +Z direction of the housing 62. The opening 131 is an opening provided in the housing 62, and is a portion through which the inside of the housing 62 is exposed. The opening 131 in this embodiment is a fan-shaped opening with arc-shaped ends, and is located in the center of the upper surface 62a.

[0057] In addition, a lid portion 132 that can open and close the opening 131 is provided. The lid portion 132 is a plate-like member. The lid portion 132 has the same shape and size as the opening 131. When the waste liquid container 60B is attached to the device main body 12, the lid portion 132 moves to an area other than the opening 131, and the lid portion 132 is in an open state. This exposes the absorber 63 inside the housing 62, and can promote drying of the waste liquid inside the housing 62. Note that the lid portion 132 may be larger than the opening 131 as long as it covers the opening 131. On the other hand, when the waste liquid container 60B is removed from the device body 12, the opening 131 is closed by the lid 132, and the lid 132 is in a closed state. This makes it possible to prevent the waste liquid from leaking from inside the housing 62.

[0058] The lid portion 132 is biased to the closed state. Specifically, the waste liquid container 60B includes a biasing member, and the lid portion 132 is maintained in the closed state by the biasing force of the biasing member. For example, one end of a coil spring serving as the biasing member is connected to the +X direction end and the -Y direction end of the lid portion 132, and the other end is connected to the upper surface 62a of the lid portion 132 on the -Y direction side. When the lid portion 132 is in the closed state, the coil spring is in a compressed state, and when the lid portion 132 is in the open state, the coil spring is in an expanded state. Therefore, by biasing the lid portion 132 to the closed state, it is possible to prevent the lid portion 132 from opening unintentionally when removed from the device main body 12.

[0059] The lid portion 132 is displaced along the attachment / detachment direction of the waste liquid container 60B. Specifically, when the waste liquid container 60B is moved in the attachment direction (+Y direction) relative to the device body 12, the lid portion 132 is displaced to the open state. On the other hand, when the waste liquid container 60B is moved in the removal direction (-Y direction) relative to the device body 12, the lid portion 132 is displaced to the closed state. The lid portion 132 is also displaced along the upper surface 62a. Furthermore, the lid portion 132 is displaced within the area of ​​the upper surface 62a when viewed from above in the open state.

[0060] Next, the mechanism for opening and closing the lid 132 of the waste liquid container 60B relative to the device main body 12 will be described. The lid portion 132 includes an abutment portion 133. The abutment portion 133 is a protrusion that protrudes in the +Z direction. In this embodiment, the abutment portion 133 is disposed at the end of the lid portion 132 opposite the end where the arc is formed. Furthermore, a rotation shaft 138 that can rotate the lid portion 132 is provided on the top surface 62a of the housing 62 between the arc end of the lid portion 132 and the abutment portion 133. The rotation shaft 138 is an axis that extends in the +Z direction from the top surface 62a. The rotation shaft 138 penetrates the lid portion 132 in the height direction. The lid portion 132 rotates about the rotation shaft 138 to be displaced between a closed state and an open state.

[0061] Furthermore, a contact portion 134 is disposed inside the device main body 12. The contact portion 134 is a protrusion that contacts the contact portion 133 during the attachment operation of the waste liquid container 60B. The -Z direction end of the contact portion 134 is located further in the +Z direction than the -Z direction end of the contact portion 133. In other words, the contact portion 134 contacts only the contact portion 133 of the waste liquid container 60B that moves in the attachment / detachment direction.

[0062] 12B, when the waste liquid container 60B is moved in the mounting direction (+Y direction) and mounted to the device main body 12 (discharge unit 55), the abutting portion 133 and the abutted portion 134 come into contact with each other. Then, by further moving in the mounting direction while in contact, the abutting portion 133 rotates counterclockwise around the rotation shaft 138. As a result, the lid portion 132 moves counterclockwise against the biasing force and is displaced to the open state. This opens the opening 131, exposing the inside of the housing 62 and facilitating drying of the waste liquid contained in the waste liquid container 60B.

[0063] 12A , when the waste liquid container 60B is moved in the removal direction (−Y direction), the lid portion 132 moves clockwise around the rotation axis 138 due to the biasing force, and when the abutting portion 133 and the abutted portion 134 separate from each other, the lid portion 132 is displaced to the closed state. Therefore, the opening 131 is closed, and leakage of the waste liquid from the opening 131 can be suppressed.

[0064] As described above, according to this embodiment, the cover part 132 can be opened and closed with a simple configuration provided with the rotation shaft 138.

[0065] 4. Fourth embodiment Next, a fourth embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted.

[0066] 13A and 13B, the waste liquid container 60C includes a housing 62 capable of storing waste liquid. The receiving portion 64 is provided on the end of an upper surface 62a of the housing 62 in the +Y direction.

[0067] An opening 141 is formed in the upper surface 62a of the housing 62. The opening 141 is an opening provided in the housing 62, and is a portion through which the interior of the housing 62 is exposed. In this embodiment, the opening 141 is provided on the +Y direction side of the upper surface 62a. In a plan view, the opening 141 has a rectangular shape.

[0068] Also provided is a lid 142 that can open and close the opening 141. The lid 142 is a plate-like member, and has the same shape and size as the opening 141. When the waste liquid container 60C is attached to the device main body 12, the lid 142 is in an open state. This exposes the absorber 63 inside the housing 62, and can promote drying of the waste liquid inside the housing 62. Note that the lid 142 may be larger than the opening 141 as long as it covers the opening 141. On the other hand, when the waste liquid container 60C is removed from the device body 12, the opening 141 is closed by the lid 142, and the lid 142 is in a closed state. This makes it possible to prevent the waste liquid from leaking from inside the housing 62.

[0069] A rotation shaft 148 extending along the X axis is disposed at the −Y end of the lid 142, and the lid 142 rotates about the rotation shaft 148, and is displaceable between a closed state and an open state. Lid 142 is biased to the closed state. For example, the torsion portion of a torsion spring serving as a biasing member is fitted onto pivot shaft 148, with one end of the torsion spring connected to lid 142 and the other end connected to housing 62. By biasing lid 142 to the closed state, it is possible to prevent lid 142 from opening unintentionally when removed from device body 12.

[0070] Next, the mechanism for opening and closing the lid 142 of the waste liquid container 60C relative to the device main body 12 will be described. The lid part 142 is displaced in association with the attachment / detachment operation of the effluent liquid receptacle 60C. Specifically, when the effluent liquid receptacle 60C is moved in the attachment direction (+Y direction) relative to the device main body 12, the +Y direction end of the lid part 142 abuts against the discharge part 55. When the effluent liquid receptacle 60C is further moved in the +Y direction, the discharge part 55 is inserted between the lid part 142 and the housing 62. Then, by further moving in the attachment direction, the lid part 142 moves clockwise around the rotation shaft 148 against the biasing force, and the lid part 142 is displaced to the open state. Therefore, the opening part 141 is opened, exposing the inside of the housing 62, and drying of the effluent liquid contained in the effluent liquid receptacle 60C can be promoted.

[0071] On the other hand, when the drainage liquid container 60C is moved in the removal direction (-Y direction), the urging force causes the lid portion 142 to move counterclockwise around the rotation axis 148, and when the discharge portion 55 and the lid portion 142 are separated, the lid portion 142 is displaced to the closed state. As a result, the opening 141 is closed, and leakage of the drainage liquid from the opening 141 can be suppressed. Note that the closed state is maintained when the +Y direction end of the lid portion 142 abuts against the restriction surface 147 at the +Y direction end of the housing 62.

[0072] As described above, according to this embodiment, the cover part 142 can be opened and closed with a simple configuration provided with the rotation shaft 148.

[0073] 5. Fifth embodiment Next, a fifth embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted. In the first embodiment, the attachment and detachment direction of the waste liquid container 60 is along the Y axis, but in this embodiment, the attachment and detachment direction of the waste liquid container 60D is along the Z axis. A specific configuration will be described below.

[0074] 14 is a perspective view showing the configuration of a recording apparatus 10A of this embodiment. The waste liquid container 60D of this embodiment is disposed at the −Y direction end of the apparatus main body 12, and at the −X direction end. When the drained liquid container 60D is attached to or detached from the device main body 12, the document reading device 14 is displaced to the open state. The document reading device 14 is provided so as to be capable of opening and closing around a rotation axis (not shown) extending parallel to the X-axis. By opening the document reading device 14, the inside of the device main body 12 is exposed, and the waste liquid receptacle 60D becomes accessible. The waste liquid receptacle 60D attached to the device main body 12 can be removed from the device main body 12 by pulling it upward. The waste liquid receptacle 60D can also be attached to the device main body 12 by inserting it downward.

[0075] 15A and 15B, the waste liquid container 60D includes a housing 150 capable of storing waste liquid. The housing 150 is a box-shaped container with a bottom and an opening 151 that opens in the +Z direction. An absorber 63 is stored inside the housing 150.

[0076] The waste liquid container 60D is provided with a lid 152 that can open and close the opening 151. The lid 152 is a plate-shaped member that is larger than the opening 151 in a plan view. In the closed state, the lid 152 is supported by the end of the housing 150 in the +Z direction. Furthermore, guides 159 are provided on the underside of lid portion 152 at the four corners of opening 151 of housing 150 to guide lid portion 152. Guides 159 move along the side walls, allowing lid portion 152 to be displaced smoothly.

[0077] The lid 152 is provided with a receiving portion 64 that receives the drainage liquid discharged from the drainage portion 55. The receiving portion 64 is an opening formed in the lid 152. In this embodiment, the tip of the drainage portion 55 is inserted into the housing 150 from the receiving portion 64. Note that the receiving portion 64 may receive the drainage portion 55 in any manner that allows the receiving portion 64 to receive the drainage liquid. In addition to the manner in which the drainage portion 55 is inserted into the receiving portion 64, the drainage portion 55 may be in contact with the receiving portion 64, or the drainage portion 55 and the receiving portion 64 may be spaced apart from each other.

[0078] When the waste liquid container 60D is attached to the device main body 12, the lid 152 is opened. This exposes the absorber 63 inside the housing 150, facilitating drying of the waste liquid inside the housing 150. On the other hand, when the waste liquid container 60D is removed from the device body 12, the lid 152 is in the closed state. This makes it possible to prevent the waste liquid from leaking from inside the housing 150.

[0079] The lid portion 152 is biased to the closed state. Specifically, the waste liquid container 60D includes a biasing member, and the lid portion 152 is maintained in the closed state by the biasing force of the biasing member. For example, one end of a coil spring serving as the biasing member is connected to the +Z direction end of the housing 150, and the other end is connected to the lid portion 152. When the lid portion 152 is in the closed state, the coil spring is in a compressed state, and when the lid portion 152 is in the open state, the coil spring is in an expanded state. Therefore, by biasing the lid portion 152 to the closed state, it is possible to prevent the lid portion 152 from opening unintentionally when the device is removed from the device main body 12. Furthermore, because the lid portion 152 closes by the biasing force, a drive mechanism for closing the lid portion 152 is not required, and the opening and closing mechanism for the lid portion 152 can be configured with a simple structure.

[0080] The lid portion 152 is displaced along the attachment / detachment direction of the waste liquid container 60D. Specifically, when the waste liquid container 60D is moved in the attachment direction (-Z direction) relative to the device body 12, the lid portion 152 is displaced to the open state. On the other hand, when the waste liquid container 60D is moved in the removal direction (+Z direction) relative to the device body 12, the lid portion 152 is displaced to the closed state.

[0081] Next, the mechanism for opening and closing the lid 152 of the waste liquid container 60D relative to the device main body 12 will be described. 15A and 15C, lid portion 152 includes abutment portion 153. Abutment portion 153 is an outer peripheral end portion of lid portion 152 in a plan view, and is a canopy portion that protrudes from both ends in the +X direction and the −X direction from housing 150 in the closed state. Furthermore, contact portions 154 are disposed within the device main body 12. The contact portions 154 are ribs that come into contact with the contact portions 153 during the attachment operation of the waste liquid container 60D. The contact portions 154 are disposed in the −Z direction of the contact portions 153. The contact portions 154 are disposed in the +X direction and the −X direction with respect to the housing 150 so as to correspond to the positions of the contact portions 153. Furthermore, the dimension between the contact portions 154 is longer than the dimension of the housing 150 in the direction along the X axis, and therefore the contact portions 154 come into contact only with the contact portions 153 without coming into contact with the housing 150 of the waste liquid container 60D that moves in the attachment / detachment direction.

[0082] 15B and 15D, when the waste liquid receptacle 60D is moved in the mounting direction (-Z direction) and mounted on the apparatus main body 12, the lower surface of the abutting portion 153 and the upper surface of the abutted portion 154 come into contact with each other. Then, by further moving in the mounting direction while in contact, the housing 150 moves in the -Z direction relative to the lid portion 152 against the biasing force, and the lid portion 152 is displaced to the open state. As a result, the opening 151 is opened to expose the inside of the housing 150, which can promote drying of the waste liquid stored in the waste liquid receptacle 60D.

[0083] 15A and 15C, when the waste liquid container 60D is moved in the removal direction (+Z direction), the lid portion 152 moves in the -Z direction due to the biasing force, and when the abutting portion 153 and the abutted portion 154 separate from each other, the lid portion 152 is displaced to the closed state. Therefore, the opening 151 is closed, and leakage of the waste liquid from the opening 151 can be suppressed. When the waste liquid container 60D is moved in the removal direction, the discharge part 55 is first retracted from the receiving part 64. When the waste liquid container 60D is attached, the discharge part 55 is inserted into the housing 150 via the receiving part 64.

[0084] As described above, according to this embodiment, the opening 151 is provided at a position separate from the receiving portion 64, and it is possible to form the opening 151 large when the waste liquid receptacle 60D is attached. This promotes drying of the waste liquid, and it is possible to increase the apparent storage capacity of the waste liquid receptacle 60D for the waste liquid, without increasing the size of the waste liquid receptacle 60D.

[0085] 6. Sixth embodiment Next, a sixth embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted. In the waste liquid container 60E of this embodiment, the attachment / detachment direction is along the Z axis, similar to the fifth embodiment.

[0086] 16A and 16B, the waste liquid container 60E includes a housing 160 capable of storing waste liquid. The housing 160 is a box-shaped container with a bottom that has an opening 161 in a portion in the +Z direction. An absorber 63 is stored inside the housing 160.

[0087] The waste liquid container 60E is provided with a lid 162 that can open and close the opening 161. The lid 162 is a plate-shaped member that is larger than the opening 161 in a plan view. In the closed state, the lid 162 is supported by the end of the housing 160 in the +Z direction.

[0088] A rotation shaft 168 extending along the X axis is disposed at the −Y end of the lid 162, and the lid 162 rotates about the rotation shaft 168, and is displaceable between a closed state and an open state. Lid 162 is biased to the closed state. For example, the torsion portion of a torsion spring serving as a biasing member is fitted onto pivot shaft 168, with one end of the torsion spring connected to lid 162 and the other end connected to top surface 160a of housing 160. By biasing lid 162 to the closed state, it is possible to prevent lid 162 from opening unintentionally when removed from device body 12. Furthermore, because lid 162 closes due to the biasing force, no drive mechanism for closing lid 162 is required, and the opening and closing mechanism for lid 162 can be configured with a simple structure.

[0089] A receiving portion 64 that receives the drainage liquid discharged from the discharge portion 55 is provided on the upper surface portion 160a of the housing 160, which is disposed in the -Y direction of the lid portion 162. The receiving portion 64 is an opening formed in the upper surface portion 160a. The tip of the discharge portion 55 is inserted into the housing 160 via the receiving portion 64.

[0090] When the waste liquid container 60E is attached to the device body 12, the lid 162 is opened, thereby exposing the absorber 63 inside the housing 160 and promoting drying of the waste liquid inside the housing 160 (FIG. 16B). On the other hand, the lid 162 is closed when the waste liquid container 60E is removed from the device body 12. This makes it possible to prevent the waste liquid from leaking from inside the housing 160 (FIG. 16A).

[0091] The lid portion 162 is displaced in accordance with the attachment / detachment direction of the waste liquid container 60E. Specifically, when the waste liquid container 60E is moved in the attachment direction (-Z direction) relative to the device body 12, the lid portion 162 is displaced to the open state. On the other hand, when the waste liquid container 60E is moved in the detachment direction (+Z direction) relative to the device body 12, the lid portion 162 is displaced to the closed state.

[0092] Next, the mechanism for opening and closing the lid 162 of the waste liquid container 60E relative to the device main body 12 will be described. The lid portion 162 includes an abutment portion 163. The abutment portion 163 is an end portion of the lid portion 162 in the +Y direction, and is a visor portion that protrudes from both ends in the +X direction and the -X direction from the housing 160 in the closed state. The abutment portion 163 is provided on the opposite side to the position where the rotation shaft 168 of the lid portion 162 is disposed. Furthermore, contact portions 164 are disposed within the device main body 12. The contact portions 164 are ribs that come into contact with the contact portions 163 during the attachment operation of the waste liquid container 60E. The contact portions 164 are disposed in the −Z direction of the contact portions 163. The contact portions 164 are disposed in the +X and −X directions of the housing 160 so as to correspond to the positions of the contact portions 163. Furthermore, since the dimension between the contact portions 164 is longer than the dimension of the housing 160 in the direction along the X axis, the contact portions 164 come into contact only with the contact portions 163 without coming into contact with the housing 160 of the waste liquid container 60E that moves in the attachment / detachment direction.

[0093] 16B, when the waste liquid container 60E is moved in the mounting direction (-Z direction) and mounted on the apparatus main body 12, the lower surface of the abutting portion 163 and the upper surface of the abutted portion 164 come into contact with each other. Then, by further moving in the mounting direction while in contact, the lid portion 162 moves clockwise around the rotation shaft 168 against the biasing force, and the lid portion 162 is relatively displaced to the open state. As a result, the opening 161 is opened to expose the inside of the housing 160, which can promote drying of the waste liquid contained in the waste liquid container 60E.

[0094] 16A, when the waste liquid container 60E is moved in the removal direction (+Z direction), the lid portion 162 moves counterclockwise around the rotation axis 168 due to the biasing force, and when the abutting portion 163 and the abutted portion 164 separate from each other, the lid portion 162 is displaced to the closed state. Therefore, the opening 161 is closed, and leakage of the waste liquid from the opening 161 can be suppressed. When the waste liquid container 60E is moved in the removal direction, the discharge part 55 is first retracted from the receiving part 64. When the waste liquid container 60E is attached, the discharge part 55 is inserted into the housing 160 via the receiving part 64.

[0095] As described above, according to this embodiment, the drying of the waste liquid is promoted when the waste liquid container 60E is attached to the device main body 12, and the apparent storage capacity of the waste liquid container 60E can be increased without increasing the size of the waste liquid container 60E.

[0096] 7. Seventh embodiment Next, a seventh embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted. In the waste liquid container 60F of this embodiment, the attachment / detachment direction is along the Z axis, similar to the fifth embodiment.

[0097] 17A and 17B, the waste liquid container 60F includes a housing 170 capable of storing waste liquid. The housing 170 is a box-shaped container with a bottom and an opening 171 that opens in the +Z direction. An absorber 63 is stored inside the housing 170.

[0098] The waste liquid container 60F is provided with a lid 172 that can open and close the opening 171. The lid 172 is a plate-shaped member that is larger than the opening 171 in a plan view. In the closed state, the lid 172 is supported by the end of the housing 170 in the +Z direction. Furthermore, guides 179 are provided on the underside of lid portion 172 at the four corners of opening 171 of housing 170 to guide lid portion 172. Guides 179 move along the side walls, allowing lid portion 172 to be displaced smoothly.

[0099] The lid portion 172 is provided with a receiving portion 64 that receives the drainage liquid discharged from the discharge portion 55. The receiving portion 64 is an opening formed in the lid portion 172. The tip of the discharge portion 55 is inserted into the housing 170 through the receiving portion 64.

[0100] When the waste liquid container 60F is attached to the device main body 12, the lid 172 is opened. This exposes the absorber 63 inside the housing 170, facilitating drying of the waste liquid inside the housing 170. On the other hand, when the waste liquid container 60F is removed from the device main body 12, the lid 172 is in the closed state. This makes it possible to prevent the waste liquid from leaking from inside the housing 170.

[0101] The lid portion 172 is displaced along the attachment / detachment direction of the waste liquid container 60F. Specifically, when the waste liquid container 60F is moved in the attachment direction (-Z direction) relative to the device body 12, the lid portion 172 is displaced to the open state. On the other hand, when the waste liquid container 60F is moved in the removal direction (+Z direction) relative to the device body 12, the lid portion 172 is displaced to the closed state.

[0102] Next, a description will be given of the opening and closing mechanism of the lid part 172 of the waste liquid container 60F relative to the device main body 12. Specifically, the opening and closing mechanism of the lid part 172 of the waste liquid container 60F is configured by a rack and pinion mechanism. The lid portion 172 includes an abutment portion 173. The abutment portion 173 is an outer peripheral end portion of the lid portion 172 in a plan view, and is an eave portion that protrudes from the housing 170 in the +Y direction in the closed state. The waste liquid container 60F also includes a first rack 174 that can come into contact with the lid portion 172, and a gear portion 175 that meshes with the first rack 174. The first rack 174 is a rod-shaped member on which a plurality of teeth are formed. The first rack 174 is disposed to extend in a direction along the Z axis. Specifically, the +Z direction end of the first rack 174 is disposed so as to be able to abut against the abutment portion 173 of the cover portion 172. The first rack 174 is configured to be movable in a direction along the Z axis. A guide plate 178a is provided to guide the first rack 174 along the movement direction of the first rack 174. Furthermore, a support portion 178b is provided to support the first rack 174 from below at the bottom dead center of the movement direction of the first rack 174 in the -Z direction. This ensures that the first rack 174 moves in a direction along the Z axis.

[0103] The gear unit 175 includes a first gear 175a and a second gear 175b. The first gear 175a and the second gear 175b rotate about shafts 176a and 176b, respectively. The first gear 175a is disposed in the +X direction of the first rack 174 and meshes with the first rack 174. The second gear 175b is disposed in the +X direction of the first gear 175a and meshes with the first gear 175a.

[0104] The device body 12 also includes a second rack 177 that meshes with the gear part 175. Specifically, the second rack 177 is disposed in the +X direction of the second gear 175b and meshes with the second gear 175b. The second rack 177 is a plate-like member on which a plurality of teeth are formed. The second rack 177 is fixedly disposed in a direction along the Z axis.

[0105] When the waste liquid container 60F is attached to the apparatus main body 12, the second rack 177 and the second gear 175b are engaged with each other while the waste liquid container 60F is moved in the attachment direction (-Z direction). As a result, the second gear 175b rotates clockwise around the shaft 176b. The first gear 175a, which engages with the second gear 175b, rotates counterclockwise around the shaft 176a. The first rack 174, which engages with the first gear 175a, moves in the +Z direction. As a result, the +Z direction end of the first rack 174 abuts against the abutment portion 173, pushing the lid portion 172 upward relative to the housing 170, and the lid portion 172 is displaced to the open state. As a result, the opening 171 is opened, exposing the interior of the housing 170, and drying of the waste liquid contained in the waste liquid container 60F can be promoted.

[0106] On the other hand, when the waste liquid container 60F is moved in the removal direction (+Z direction), the second gear 175b rotates counterclockwise around the shaft 176b. The first gear 175a rotates clockwise around the shaft 176a. The first rack 174 then moves in the -Z direction due to the biasing force or gravity, and the lid 172 is displaced to the closed state. This closes the opening 171, making it possible to prevent leakage of the waste liquid. The biasing force can be achieved by a biasing member. Specifically, the waste liquid container 60F includes a biasing member, and the lid 172 is maintained in the closed state by the biasing force of the biasing member. For example, one end of a coil spring serving as the biasing member is connected to the end of the housing 170 in the +Z direction, and the other end is connected to the lid 172. When the lid 172 is in the closed state, the coil spring is in a compressed state, and when the lid 172 is in the open state, the coil spring is in an expanded state. Therefore, by biasing the lid 172 to the closed state, it is possible to prevent the lid 172 from opening unintentionally when the device is removed from the device main body 12. When the waste liquid container 60F is moved in the removal direction, the discharge part 55 is first retracted from the receiving part 64. When the waste liquid container 60F is attached, the discharge part 55 is inserted into the housing 170 via the receiving part 64.

[0107] As described above, according to this embodiment, the lid portion 172 is opened by the rack and pinion mechanism during the process of attaching the waste liquid container 60F, so no drive source for opening the lid portion 172 is required, and the opening and closing mechanism for the lid portion 172 can be realized with a simple configuration. The rack and pinion mechanism may be provided on the −Y direction side of the housing 170 in addition to the +Y direction side of the housing 170. In this way, the opening and closing operation of the lid part 172 can be performed more smoothly. The number of gears constituting the gear portion 175 is arbitrary within the range of matching with the displacement direction of the first rack 174. Also, the first rack 174 may be configured to be fixed to the −Z direction end surface of the lid portion 172. In this case, the support portion 178b becomes unnecessary.

[0108] 8. Eighth embodiment Next, an eighth embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted. In the fifth embodiment, the installation direction of the waste liquid container 60D is the -Z direction, and the removal direction is the +Z direction, but this is not limiting. In the present embodiment, the installation direction of the waste liquid container 60G is the +Z direction, and the removal direction is the -Z direction. A specific configuration will be described below.

[0109] 18A is a perspective view showing the configuration of a recording apparatus 10B of this embodiment. The waste liquid container 60G of this embodiment is disposed at the −Y direction end and −X direction end in the apparatus main body 12. When the waste liquid container 60G is to be attached to or detached from the device body 12, the bottom cover 200 attached to the bottom surface of the device body 12 is displaced to the open state.

[0110] 18B, the effluent receptacle 60G is exposed, making it possible to access the effluent receptacle 60G. Then, as shown in Fig. 18C, by pulling the effluent receptacle 60G attached to the device main body 12 downward, the effluent receptacle 60G can be removed from the device main body 12. Also, by inserting the effluent receptacle 60G upward, the effluent receptacle 60G can be attached to the device main body 12.

[0111] 19A and 19B, the waste liquid container 60G includes a housing 180 capable of storing waste liquid. The housing 180 is a box-shaped container with a bottom and an opening 181 that opens in the +Z direction. An absorber 63 is stored inside the housing 180.

[0112] The waste liquid container 60G is provided with a lid 182 that can open and close the opening 181. The lid 182 is a plate-shaped member that is larger than the opening 181 in a plan view. In the closed state, the lid 182 is supported by the end of the housing 180 in the +Z direction.

[0113] A rotation shaft 188 extending along the X axis is disposed at the -Y end of the lid 182, and the lid 182 rotates around the rotation shaft 188, and is displaceable between a closed state and an open state. Lid 182 is biased to the closed state. For example, the torsion portion of a torsion spring serving as a biasing member is fitted onto pivot shaft 188, with one end of the torsion spring connected to lid 182 and the other end connected to the top surface of housing 180. By biasing lid 182 to the closed state, it is possible to prevent lid 182 from opening unintentionally when removed from device body 12. Furthermore, because lid 182 closes due to the biasing force, no drive mechanism for closing lid 182 is required, and the opening and closing mechanism for lid 182 can be configured with a simple structure.

[0114] The lid portion 182 is provided with a receiving portion 64 that receives the drainage liquid discharged from the discharge portion 55. The receiving portion 64 is an opening formed in the lid portion 182. The tip of the discharge portion 55 is inserted into the housing 180 via the receiving portion 64.

[0115] When the waste liquid container 60G is attached to the device main body 12, the lid 182 is opened, thereby exposing the absorber 63 inside the housing 180 and promoting drying of the waste liquid inside the housing 180 (FIG. 19B). On the other hand, the lid 182 is closed when the waste liquid container 60G is removed from the device body 12. This makes it possible to prevent the waste liquid from leaking from inside the housing 180 (FIG. 19A).

[0116] The lid portion 182 is displaced in accordance with the attachment / detachment direction of the waste liquid container 60G. Specifically, when the waste liquid container 60G is moved in the attachment direction (+Z direction) relative to the device body 12, the lid portion 182 is displaced to the open state. On the other hand, when the waste liquid container 60G is moved in the removal direction (-Z direction) relative to the device body 12, the lid portion 182 is displaced to the closed state.

[0117] Next, the mechanism for opening and closing the lid 182 of the waste liquid container 60G relative to the device main body 12 will be described. Lid 182 includes abutment 183. Abutment 183 is the −Y direction end of lid 182, and is an eave portion that protrudes from the −Y direction end from housing 180 in the closed state. Abutment 183 is located on the −Y direction side of the position where rotation shaft 188 is located. Furthermore, a contact portion 184 is disposed within the device main body 12. The contact portion 184 is a rib that contacts the contact portion 183 during the attachment operation of the waste liquid container 60G. The contact portion 184 is disposed in the +Z direction of the contact portion 183. Furthermore, the contact portion 164 is disposed in the -Y direction of the rotation shaft 188 in plan view. Therefore, the contact portion 184 contacts only the contact portion 183.

[0118] 19B, when the waste liquid container 60G is moved in the mounting direction (+Z direction) and mounted to the device main body 12, the upper surface of the abutting portion 183 and the lower surface of the abutted portion 184 come into contact with each other. Then, by further moving in the mounting direction while in contact, the lid portion 182 moves clockwise around the rotation shaft 188 against the biasing force, and the lid portion 182 is displaced to the open state relative to the housing 180. Then, the waste liquid container 60G is mounted to the device main body 12. As a result, the opening 181 is opened to expose the inside of the housing 180, which can promote drying of the waste liquid contained in the waste liquid container 60G.

[0119] 19A, when the drained liquid container 60G is moved in the removal direction (-Z direction), the lid portion 182 moves counterclockwise around the rotation axis 188 due to the biasing force, and when the abutting portion 183 and the abutted portion 184 move away from each other, the lid portion 182 is displaced to the closed state. Since the drained liquid container 60G is removed from the device body 12 with the opening 181 closed, leakage of the drained liquid from the opening 181 can be suppressed. When the waste liquid container 60G is moved in the removal direction, the discharge part 55 is first retracted from the receiving part 64. When the waste liquid container 60G is attached, the receiving part 64 is attached to the discharge part 55.

[0120] As described above, according to this embodiment, the drying of the waste liquid is promoted when the waste liquid container 60G is attached to the device main body 12, and the apparent storage capacity of the waste liquid container 60G can be increased without increasing the size of the waste liquid container 60G.

[0121] 9. Ninth embodiment Next, a ninth embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and redundant explanations will be omitted. In the waste liquid container 60H of this embodiment, the mounting direction is the +Z direction, and the removal direction is the −Z direction, similar to the eighth embodiment.

[0122] 20A and 20B, the waste liquid container 60H includes a housing 190 capable of storing waste liquid. The housing 190 is a box-shaped container with a bottom and an opening 191 that opens in the +Z direction. An absorber 63 is stored inside the housing 190.

[0123] The waste liquid container 60H is provided with a lid 192 that can open and close the opening 191. The lid 192 is a plate-shaped member that is larger than the opening 191 in a plan view. In the closed state, the lid 192 is supported by the end of the housing 190 in the +Z direction. Furthermore, guides 199 are provided on the underside of lid portion 192 at the four corners of opening 191 of housing 190 to guide lid portion 192. Guides 199 move along the side walls, allowing lid portion 192 to be displaced smoothly.

[0124] The lid portion 192 is provided with a receiving portion 64 that receives the drainage liquid discharged from the discharge portion 55. The receiving portion 64 is an opening formed in the lid portion 192. The tip of the discharge portion 55 is inserted into the housing 190 via the receiving portion 64.

[0125] When the waste liquid container 60H is attached to the device main body 12, the lid 192 is opened. This exposes the absorber 63 inside the housing 190, facilitating drying of the waste liquid inside the housing 190. On the other hand, when the waste liquid container 60H is removed from the device main body 12, the lid portion 192 is in the closed state. This makes it possible to prevent the waste liquid from leaking from inside the housing 190.

[0126] The lid portion 192 is displaced along the attachment / detachment direction of the waste liquid container 60H. Specifically, when the waste liquid container 60H is moved in the attachment direction (+Z direction) relative to the device body 12, the lid portion 192 is displaced to the open state. On the other hand, when the waste liquid container 60H is moved in the removal direction (-Z direction) relative to the device body 12, the lid portion 192 is displaced to the closed state.

[0127] Next, a description will be given of the opening and closing mechanism of the lid portion 192 of the waste liquid container 60H relative to the device main body 12. Specifically, the opening and closing mechanism of the lid portion 192 of the waste liquid container 60H is configured by a rack and pinion mechanism. The lid portion 192 includes an abutment portion 193. The abutment portion 193 is the outer peripheral edge of the lid portion 192 in a plan view, and is a canopy portion that protrudes from the +Y direction end of the housing 190 in the closed state. The waste liquid container 60H also includes a first rack 194 that can come into contact with the lid portion 192, and a gear 195 that meshes with the first rack 194 and serves as a gear portion. The first rack 194 is a rod-shaped member on which a plurality of teeth are formed. The first rack 194 is disposed to extend in a direction along the Z axis. Specifically, the +Z direction end of the first rack 194 is disposed so as to be able to abut against the abutment portion 193 of the cover portion 192. The first rack 194 is configured to be movable in a direction along the Z axis. A guide plate 198a is provided to guide the first rack 194 along the movement direction of the first rack 194. Furthermore, a support portion 198b is provided to support the first rack 194 from below at the bottom dead center of the movement direction of the first rack 194 in the -Z direction. This ensures that the first rack 194 moves in a direction along the Z axis.

[0128] The gear 195 meshes with the first rack 194. The gear 195 is disposed in the +X direction of the first rack 194. The gear 195 rotates around a shaft 196.

[0129] The device body 12 also includes a second rack 197 that meshes with the gear 195. The second rack 197 is a plate-like member on which a plurality of teeth are formed. The second rack 197 is disposed in the +X direction of the gear 195. The second rack 197 is fixedly disposed in a direction along the Z axis.

[0130] When the waste liquid container 60H is attached to the apparatus main body 12, the waste liquid container 60H is moved in the attachment direction (+Z direction) while the second rack 197 and the gear 195 are engaged with each other. This causes the gear 195 to rotate counterclockwise around the shaft 196. The first rack 194, which engages with the gear 195, moves in the +Z direction. As a result, the +Z-direction end of the first rack 194 abuts against the abutment portion 193, pushing the lid portion 192 upward relative to the housing 190, and the lid portion 192 is displaced to the open state ( FIG. 20B ). This opens the opening 191, exposing the interior of the housing 190 and facilitating drying of the waste liquid contained in the waste liquid container 60H.

[0131] On the other hand, when the waste liquid container 60H is moved in the removal direction (-Z direction), the gear 195 rotates clockwise around the shaft 196. Then, the first rack 194 moves in the -Z direction due to the biasing force or gravity, and the lid 192 is displaced to the closed state (FIG. 20A). This closes the opening 191, making it possible to prevent leakage of the waste liquid. The biasing force can be achieved by a biasing member. Specifically, the waste liquid container 60H includes a biasing member, and the lid 192 is maintained in the closed state by the biasing force of the biasing member. For example, one end of a coil spring serving as the biasing member is connected to the end of the housing 190 in the +Z direction, and the other end is connected to the lid 192. When the lid 192 is in the closed state, the coil spring is in a compressed state, and when the lid 192 is in the open state, the coil spring is in an expanded state. Therefore, by biasing the lid 192 to the closed state, it is possible to prevent the lid 192 from opening unintentionally when the device is removed from the device main body 12. When the waste liquid container 60H is moved in the removal direction, the discharge part 55 is first retracted from the receiving part 64. When the waste liquid container 60H is attached, the receiving part 64 is attached to the discharge part 55.

[0132] As described above, according to this embodiment, the lid portion 192 is opened by the rack and pinion mechanism during the process of attaching the waste liquid container 60H, so no drive source is required to open the lid portion 192, and the opening and closing mechanism for the lid portion 192 can be realized with a simple configuration. The rack and pinion mechanism may be provided on the −Y direction side of the housing 190 in addition to the +Y direction side of the housing 190. In this way, the opening and closing operation of the lid part 192 can be performed more smoothly. The number of gears constituting the gear portion is arbitrary within the range of matching with the displacement direction of the first rack 194. Also, the first rack 194 may be fixed to the −Z direction end surface of the lid portion 192. In this case, the support portion 198b becomes unnecessary. The first to ninth embodiments may be combined as appropriate. [Explanation of symbols]
