The liquid ejecting apparatus according to the present embodiment is an ink jet printer that prints characters or images by ejecting ink, which is one example of a liquid, onto a medium such as paper. In the following description, for the sake of easy understanding of the description, some of the components are not illustrated in the drawings or the same kind of hatching is used.
As shown in fig. 1, the multifunction device 10 includes: a liquid ejecting apparatus 11 that ejects liquid onto the medium M; and a reading device 12 that reads characters or images written on a document. In the present embodiment, in a state where the multifunction peripheral 10 is placed on a horizontal plane, the width direction of the multifunction peripheral 10 is defined as a "scanning direction X", the front-back direction of the multifunction peripheral 10 is defined as a "depth direction Y", and the height direction of the multifunction peripheral 10 is defined as a "vertical direction Z". The scanning direction X, the depth direction Y, and the vertical direction Z are different (orthogonal) directions from each other. Further, one end in the scanning direction X is also referred to as "first end X1", and the other end in the scanning direction X is also referred to as "second end X2".
As shown in fig. 1 and 2, the liquid ejecting apparatus 11 includes: a frame 21 that constitutes an exterior of the liquid ejecting apparatus 11; a medium storage unit 22 that stores the medium M; a mounting portion 24 to which a liquid container 23 for containing liquid is mounted; an operation unit 25 that receives an input from a user; and a hinge portion 26 that rotatably supports the reading device 12. As shown in fig. 3 and 4, the liquid ejecting apparatus 11 includes: a feeding unit 30 that feeds the medium M from the medium storage unit 22; a conveying unit 40 that conveys the medium M; a support portion 50 that supports the medium M: and a liquid ejecting unit 60 that ejects liquid to the medium M. The liquid ejecting apparatus 11 further includes: a maintenance device 70 that performs maintenance on the liquid ejecting unit 60; and a holding portion 90 that holds the waste liquid container 80 that contains the liquid (waste liquid) discharged from the liquid ejecting unit 60.
The structure of the liquid ejecting apparatus 11 according to the external appearance will be described with reference to fig. 1 and 2.
As shown in fig. 2, the frame 21 has a box shape opened upward. The housing 21 houses components of the liquid ejecting apparatus 11 such as the feeding unit 30, the conveying unit 40, the support unit 50, the liquid ejecting unit 60, the maintenance device 70, and the holding unit 90. A discharge port 211 for discharging the medium M is provided on the front surface of the frame 21. The discharge port 211 is formed in the longitudinal direction X and opens between the operation unit 25 and the medium accommodating unit 22 in the vertical direction Z.
The medium storage 22 is disposed at a lower portion of the housing 21. The medium storage section 22 is provided to be attachable to and detachable from the housing 21 in the depth direction Y. The medium storage unit 22 is a tray or a cassette that stores a plurality of media M stacked in the vertical direction Z.
The mounting portion 24 is provided so as to protrude forward on the first end X1 side of the frame 21 in the scanning direction X. The mounting portion 24 is mounted with a plurality of liquid containers 23 for containing different types of liquids, arranged in the scanning direction X. The liquid container 23 may be a replaceable cartridge or a tank capable of being replenished with liquid.
The operation unit 25 is disposed at an upper portion of the front surface of the housing 21 so as to be spaced apart from the medium accommodating unit 22 in the vertical direction Z. The operation portion 25 has a rectangular plate shape. The operation unit 25 includes: a power button 251 for operating the liquid ejecting apparatus 11; and a display screen 252 that displays various information of the liquid ejecting apparatus 11. The display screen 252 may be a touch panel type liquid crystal screen, for example. The operation unit 25 receives an input from the outside by a user of the liquid ejecting apparatus 11 when various settings of the liquid ejecting apparatus 11 are changed or the liquid ejecting apparatus 11 is operated.
The hinge 26 is disposed on the upper back of the frame 21. The hinge portion 26 allows the reading apparatus 12 to rotate relative to the housing 21 about a rotation axis extending along the scanning direction X. Specifically, the hinge portion 26 rotates the reader 12 between a "first position" in which the reader 12 covers the opening 212 in the upper portion of the housing 21 as shown in fig. 1, and a "second position" in which the opening 212 of the housing 21 is opened as shown in fig. 2.
Next, the internal structure of the liquid ejecting apparatus 11 will be described with reference to fig. 3 and 4.
As shown in fig. 4, the feeding unit 30 includes a pickup roller 31, and the pickup roller 31 feeds the uppermost medium M among the plurality of media M stacked in the medium storage unit 22 to the conveying unit 40. The pickup roller 31 is biased downward toward the medium M stacked in the medium storage 22.
As shown in fig. 4, the conveying unit 40 includes: a first conveying roller 41 and a first driven roller 42 disposed behind the support portion 50; and a second conveying roller 43 and a second driven roller 44 disposed in front of the support portion 50. The first conveying roller 41 and the second conveying roller 43 are disposed below the conveyance path FP of the medium M, and the first driven roller 42 and the second driven roller 44 are disposed above the conveyance path FP of the medium M. The transport unit 40 rotates the transport rollers 41 and 43 with the transport rollers 41 and 43 and the driven rollers 42 and 44 sandwiching the medium M fed from the feeding unit 30. In this way, the conveying unit 40 conveys the medium M toward the support unit 50. The second conveying roller 43 and the second driven roller 44 disposed in front of the support portion 50 may be a pressing mechanism for suppressing the lifting of the medium M.
As shown in fig. 3 and 4, the support portion 50 has a rectangular plate shape with the scanning direction X as the longitudinal direction and the depth direction Y as the short direction. The support portion 50 is disposed below the liquid ejecting unit 60, and constitutes a part of the conveying path FP of the medium M. The support portion 50 may have a structure for sucking and adsorbing the medium M in order to stabilize the posture of the supported medium M.
Here, in the liquid ejecting apparatus 11 of the present embodiment, the "conveying path FP" as a passage of the medium M from the medium accommodating portion 22 to the discharge port 211 is reversed in the depth direction Y. That is, the medium M stored in the medium storage 22 is moved backward by the feeder 30, and the medium M on the support 50 is moved forward by the feeder 40. In the following description, the moving direction of the medium M conveyed on the support portion 50 by the conveying portion 40 is referred to as "conveying direction F". That is, the upstream side in the transport direction F becomes the rear side of the liquid ejecting apparatus 11, and the downstream side in the transport direction F becomes the front side of the liquid ejecting apparatus 11.
As shown in fig. 3 and 4, the liquid ejecting unit 60 includes: a liquid ejection head 62 having nozzles 61 that eject liquid; a carriage 63 on which the liquid ejecting head 62 is mounted; a guide shaft 64 that guides movement of the carriage 63 in the scanning direction X: and a supply flow path 65 that connects the liquid ejecting head 62 and the liquid container 23.
The liquid ejecting head 62 is mounted on the carriage 63 so that an opening surface of the nozzle 61 faces the direction of the support portion 50. The carriage 63 is disposed above the conveying path FP (the support portion 50). The carriage 63 is configured to be capable of reciprocating in the scanning direction X by a movement mechanism, not shown. The supply flow path 65 is a tube having elasticity and capable of deforming in accordance with the movement of the carriage 63. The supply flow path 65 is disposed between the carriage 63 and the holding portion 90 in the conveying direction F.
The liquid ejecting unit 60 ejects ink from the liquid ejecting head 62 toward the medium M while moving the carriage 63 in the scanning direction X. In the following description, a path through which the carriage 63 moves in the scanning direction X will also be referred to as a "moving path". The position of the liquid ejecting head 62 mounted on the carriage 63 facing the support portion 50 on the moving path is also referred to as an "ejecting position". The ejection position is a position of the carriage 63 at which the liquid ejection head 62 can eject the liquid toward the medium M.
As shown in fig. 3, the maintenance device 70 is disposed on the first end X1 side of the support portion 50 in the scanning direction X and behind the mounting portion 24 in the conveying direction F. That is, the maintenance device 70 is disposed adjacent to the support portion 50 in the scanning direction X. The maintenance device 70 includes: a lid 71 opened upward; a waste liquid channel 72 whose upstream end is connected to the lid 71; a suction portion 73 provided in the middle of the waste liquid flow passage 72; a wiping member 74 capable of wiping an opening surface of the liquid ejecting head 62; a slider 75 that holds the cover 71; and a base 76 that supports the slider 75 so as to be relatively movable. The suction unit 73 is configured to be capable of performing a suction operation for sucking the inside of the cover 71. The slider 75 has an engagement projection 751 projecting upward at a first end X1 in the scanning direction X.
In the maintenance device 70, when the carriage 63 moving toward the first end X1 engages with the engagement projection 751, the slider 75 moves obliquely upward in accordance with the movement of the carriage 63. Thereby, the cap 71 comes into contact with the opening surface of the liquid ejecting head 62, and the space opened by the nozzle 61 becomes a closed space. The operation of forming the closed space by the cap 71 is referred to as "capping". In fig. 3, the positions of the cap 71 and the slider 75 when capping are indicated by two-dot chain lines.
The position of the carriage 63 at which the liquid jet head 62 mounted on the carriage 63 faces the maintenance device 70 in the movement path is also referred to as a "maintenance position". The maintenance position is a position of the carriage 63 when the liquid ejecting head 62 is capped by the cap 71, and is a position closer to the first end X1 in the scanning direction X of the moving path of the carriage 63.
Further, if the suction unit 73 is driven at the time of capping, the interior of the liquid ejecting head 62 is sucked through the nozzle 61. In this way, the operation of sucking the liquid in the liquid ejecting head 62 by the suction unit 73 through the nozzle 61 is referred to as "suction cleaning". In the present embodiment, an example of the "suction mechanism" is configured to include the cover 71 and the suction portion 73.
As shown in fig. 3, the holding portion 90 is disposed above the conveying path FP and the discharge port 211 (medium accommodating portion 22) in the vertical direction Z. The holding portion 90 is disposed on the downstream side of the movement path of the carriage 63 and on the upstream side of the operation portion 25 in the conveying direction F. The holding portion 90 includes: a holder 91 that holds a waste liquid container 80 capable of containing waste liquid generated by suction cleaning or the like; a connecting portion 92 communicating with a downstream end of the waste liquid flow passage 72; and a substrate connection portion 93 electrically connectable to the waste liquid container 80.
The bracket 91 has: a first wall portion 911 and a second wall portion 912 that are arranged at intervals in the conveying direction F; and a third wall portion 913 and a fourth wall portion 914 that connect the first wall portion 911 and the second wall portion 912 in the conveying direction F. The first wall portion 911 is disposed on the upstream side in the conveying direction F, and the second wall portion 912 is disposed on the downstream side in the conveying direction F. The third wall part 913 connects the first end X1 in the scanning direction X of the first wall part 911 and the first end X1 in the scanning direction X of the second wall part 912 to each other. The fourth wall portion 914 connects the lower end of the first wall portion 911 and the lower end of the second wall portion 912 to each other. In this way, the first wall portion 911, the second wall portion 912, and the third wall portion 913 constitute the side walls of the bracket 91, and the fourth wall portion 914 constitutes the bottom wall of the bracket 91. In the present embodiment, the first wall portion 911 and the second wall portion 912 are shorter than the fourth wall portion 914 in the scanning direction X, but the first wall portion 911 and the second wall portion 912 may be made to have a length similar to that of the fourth wall portion 914.
The connecting portion 92 has a needle shape. The connecting portion 92 extends from the first end X1 in the scanning direction X toward the second end X2 on the third wall portion 913 located near the first end X1 of the holding portion 90. The connecting portion 92 is provided at a position closer to the first wall portion 911 than the second wall portion 912 in the conveying direction F. In other words, the connection portion 92 is provided at a position closer to the end portion on the upstream side than the end portion on the downstream side in the conveyance direction F of the holding portion 90 (the bracket 91). The connection portion 92 is inserted into the waste liquid container 80, thereby introducing the waste liquid supplied from the maintenance device 70 into the waste liquid container 80.
The substrate connection portion 93 is provided on the second wall portion 912 so as to electrically contact the first wall portion 911. That is, the substrate connection portion 93 is provided on the second wall portion 912 close to the operation portion 25, out of the first wall portion 911 and the second wall portion 912.
As shown in fig. 3, the waste liquid container 80 has a substantially rectangular parallelepiped shape. The waste liquid container 80 is a container for containing waste liquid (for example, waste ink) discharged by the suction operation of the maintenance device 70. Preferably, an absorber capable of absorbing the waste liquid is disposed inside the waste liquid container 80.
An introduction portion 81 connected to the connection portion 92 is provided on a side surface of the waste liquid container 80 intersecting the longitudinal direction. Preferably, the introduction portion 81 is sealed with an O-ring or the like so that the waste liquid does not leak when the connection portion 92 is inserted and removed.
A circuit board 82 connected to the board connection portion 93 of the holding portion 90 is provided on a side surface of the waste liquid container 80 extending in the longitudinal direction. The circuit board 82 is a sheet-like IC chip, and is provided with electrical contacts facing outward. The circuit board 82 may store information relating to the specification of the waste liquid container 80, for example, or may sequentially store the amount of waste liquid contained in the waste liquid container 80. That is, the liquid ejecting apparatus 11 can determine whether or not the waste liquid container 80 mounted on the holding portion 90 is an appropriate waste liquid container 80 based on the information stored in the circuit board 82.
The waste liquid container 80 is attached to the holding portion 90 when moving in a direction from the second end X2 toward the first end X1 in the scanning direction X with respect to the holding portion 90. That is, the introduction portion 81 is connected to the connection portion 92, and the distal end of the connection portion 92 is positioned inside the waste liquid container 80. The circuit board 82 and the board connection portion 93 are connected to each other, and the liquid ejecting apparatus 11 can acquire information of the waste liquid container 80. On the other hand, the waste liquid container 80 is detached from the holding unit 90 when moving in the direction from the first end X1 to the second end X2 in the scanning direction X with respect to the holding unit 90. In this manner, the holding portion 90 detachably holds the waste liquid container 80.
Further, it is preferable that the holding portion 90 and the waste liquid container 80 are provided with a structure for limiting the attachment relationship of the waste liquid container 80 to the holding portion 90. For example, a configuration may be adopted in which a concave portion is provided on one of the holding portion 90 and the waste liquid container 80 and a convex portion is provided on the other, thereby preventing the waste liquid container 80 from being attached to the holding portion 90 in a direction different from the original direction in the vertical direction Z.
As shown in fig. 1 and 2, the reading device 12 includes: a document table 121 on which a document is placed; and a document cover 122 that covers the document table 121. At least a portion of the document table 121 on which a document is placed is formed of a transparent glass plate. An image scanner (not shown) for reading a document placed on the document table 121 is provided below the document table 121. The document cover 122 is relatively rotated with respect to the document table 121 by the hinge portion 26. Specifically, the document cover 122 rotates between a position covering the document table 121 and a position exposing the document table 121.
As described above, the reader 12 rotates with respect to the liquid ejecting apparatus 11 between the first position covering the opening 212 of the housing 21 and the second position opening the opening 212 of the housing 21. That is, in the present embodiment, the reader 12 corresponds to an example of a "cover" in that it opens and closes the opening 212 of the housing 21. As shown in fig. 2, when the reading device 12 is disposed at the second position, the holding portion 90 and the waste liquid container 80 attached to the holding portion 90 are exposed through the opening 212 of the housing 21.
Next, an operation of the liquid ejecting apparatus 11 of the present embodiment will be described.
In the liquid ejecting apparatus 11 according to the present embodiment, when the waste liquid container 80 is replaced, the user places the reading device 12 at the second position to expose the components of the liquid ejecting apparatus 11. Next, the user moves the used waste liquid container 80 in a direction from the first end X1 toward the second end X2 in the scanning direction X. In this way, the used waste liquid container 80 is detached from the holding portion 90. Thereafter, as shown in fig. 5, in a state where the unused waste liquid container 80 is loaded on the carriage 91 of the holding section 90, the user moves the waste liquid container 80 in a direction from the second end X2 in the scanning direction X toward the first end X1. Then, the waste liquid container 80 is attached to the holding portion 90. As described above, according to the present embodiment, since the holding portion 90 to which the waste liquid container 80 is attached is provided on the front side of the liquid ejecting apparatus 11, the user can easily perform maintenance of the waste liquid container 80. The maintenance as referred to herein is an operation of replacing the waste liquid container 80, confirming whether the waste liquid container 80 can normally contain waste liquid, or confirming the amount of waste liquid contained in the waste liquid container 80.
According to the embodiments described above, the following effects can be obtained.
(1) The holding portion 90 is disposed above the conveyance path FP of the medium M and downstream (forward) in the conveyance direction F from the movement path of the carriage 63. Therefore, the user of the liquid ejecting apparatus 11 becomes easy to load and unload the waste liquid container 80 from above the liquid ejecting apparatus 11, the downstream side in the conveying direction F, and the like. As a result, the waste liquid container 80 can be maintained well.
(2) The waste liquid container 80 is held by the holding portion 90 at a position above the discharge port 211 of the medium M. Therefore, the waste liquid container 80 is more easily maintained. Further, when the medium M is clogged in the vicinity of the discharge port 211 of the conveying path FP, the clogging of the medium M can be released without interfering with the waste liquid container 80.
(3) The waste liquid container 80 can be disposed in a region that is likely to become a dead space (dead space) between the movement path of the carriage 63 and the operation portion 25, and thus, the liquid ejecting apparatus 11 can be prevented from being increased in size. Further, the region between the movement path and the operation unit 25 is easily a region long in the scanning direction X, and the length of the waste liquid container 80 in the longitudinal direction can be set to be close to the movement path length. That is, the waste liquid container 80 can be easily increased in capacity.
(4) By providing the connecting portion 92 at a position closer to the first end X1 in the scanning direction X of the holding portion 90, the distance between the cover 71 (suction mechanism) and the connecting portion 92 is shortened as compared with the case of providing the connecting portion at a position closer to the second end X2. That is, the waste liquid flow path 72 from the lid 71 to the connection portion 92 is shortened, and the risk of leakage of waste liquid can be reduced. Further, the maintainability of the waste liquid channel 72 can be improved.
(5) The connection portion 92 is extended along the scanning direction X, and the waste liquid container 80 is moved in the direction opposite to the direction in which the connection portion 92 is extended, whereby the waste liquid container 80 and the connection portion 92 can be connected to each other. Further, compared to the case where the connection portion 92 extends along the vertical direction Z, when the waste liquid container 80 is attached and detached, the waste liquid is less likely to leak downward from the connection portion 92 or the waste liquid container 80.
(6) Since the connecting portion 92 is provided at a position of the holding portion 90 closer to the moving path in the conveying direction F, the connecting portion 92 is disposed at a position farther from the operation portion 25 than in the case of being provided at a position closer to the operation portion 25. Therefore, even if liquid leaks from the connection portion 92, such liquid can be suppressed from reaching the electrical system of the operation portion 25.
(7) By providing the substrate connection portion 93 at a position of the holding portion 90 close to the operation portion 25 in the conveying direction F, the distance between the substrate connection portion 93 and the operation portion 25 is shortened. As a result, the electric wiring to operation unit 25 and substrate connection unit 93 can be collectively implemented. Further, the maintainability of the wiring becomes good.
(8) The mfp 10 includes a reading device 12, and the reading device 12 is rotatable between a first position and a second position. Therefore, when the reader 12 is disposed at the first position, the components inside the housing 21 can be protected. On the other hand, when the reader 12 is disposed at the second position, the waste liquid container 80 exposed through the opening 212 can be maintained.
(9) The reading device 12 rotates about a hinge portion 26 provided behind the liquid ejecting apparatus 11. Therefore, by disposing the reading device 12 at the second position, the front of the liquid ejecting apparatus 11 is opened greatly. Therefore, the waste liquid container 80 disposed on the front side of the liquid ejecting apparatus 11 is more excellent in maintainability.
The above embodiment may be modified as follows.
The liquid ejecting apparatus 11 may include a liquid storage unit that stores liquid that is periodically ejected from the liquid ejecting head 62 in order to maintain the liquid ejecting performance of the liquid ejecting head 62. In this case, the waste liquid container 80 may contain the liquid (waste liquid) contained in the liquid containing section.
The holding portion 90 may not include the substrate connecting portion 93. In this case, the waste liquid container 80 may not include the circuit board 82.
The mfp 10 may not include the reading device 12. In this case, the liquid ejecting apparatus 11 preferably includes a cover that covers the opening 212 of the housing 21. The cover may open and close the opening 212 by rotating relative to the housing 21, or may open and close the opening 212 by sliding relative to the housing 21.
The mounting direction of the waste liquid container 80 to the holding portion 90 may not be the scanning direction X. For example, the waste liquid container 80 may be attached to the holding portion 90 in a downward direction. In this case, it is preferable that the holding portion 90 (fourth wall portion 914) has a connecting portion extending upward, and the waste liquid container 80 has an introduction portion on a lower surface thereof. Accordingly, the waste liquid container 80 is attached to the holding portion 90 only by moving the waste liquid container 80 downward.
The holding portion 90 may hold the waste liquid container 80 in a non-detachable manner. Even in such a case, the maintenance of the waste liquid container 80 is improved by making it easy for the user to load and unload the waste liquid container 80 held by the holding portion 90. The maintenance referred to herein is an operation of confirming whether the waste liquid container 80 can normally contain the waste liquid, or confirming the amount of the waste liquid contained in the waste liquid container 80.
The liquid ejecting apparatus 11 may be a so-called carriage-mounted liquid ejecting apparatus 11 in which the liquid container 23 is mounted on the carriage 63. In this case, the holding portion 90 may be provided in the region where the mounting portion 24 is provided in the present embodiment. Accordingly, the liquid container 23 can be increased in capacity by utilizing the fact that the range in which the liquid container 23 can be arranged in the scanning direction X is increased.
The shape of the waste liquid container 80 may not be substantially rectangular parallelepiped. The waste liquid container 80 may be appropriately changed in shape according to the internal space of the liquid ejecting apparatus 11.
The holding unit 90 may include a detection unit that detects the amount of liquid discharged from the waste liquid container 80. Accordingly, the replacement timing of the waste liquid container 80 becomes easy to know. Preferably, the detection unit is provided at the second end X2 of the holding unit 90 opposite to the first end X1 at which the connection unit 92 is provided.
The liquid ejecting apparatus 11 may include a shielding portion that covers only the waste liquid container 80 attached to the holding portion 90. In this case, the shielding portion is preferably detachable from the housing 21. Accordingly, even in a state where the reading device 12 is disposed at the second position, the user can be prevented from inadvertently touching the waste liquid container 80.
Preferably, the connection portion 92 is provided at a position above the holding portion 90 in the vertical direction Z. Accordingly, the waste liquid already stored in the waste liquid storage body 80 can be suppressed from flowing back through the connection portion 92.
Preferably, a portion of the waste liquid container 80 that becomes a bottom portion in the attached state to the holding portion 90 is inclined downward in the longitudinal direction as being apart from the introduction portion 81. Accordingly, the liquid introduced into the waste liquid container 80 through the introduction portion 81 is made to easily flow to the second end X2. That is, it is possible to suppress absorption of the waste liquid by only a part of the absorber provided inside the waste liquid container 80.
The waste liquid container 80 may include a grip portion at an upper portion thereof. Accordingly, the user can easily attach and detach the waste liquid container 80 to and from the holding portion 90 by gripping the gripping portion. When the waste liquid container 80 is provided with the grip, it is preferably provided at a position close to the first end X1 of the holding portion 90 in the scanning direction X. Accordingly, when the waste liquid container 80 detached from the holding portion 90 is conveyed, the liquid can be prevented from leaking from the introducing portion 81 by the point that the introducing portion 81 is easily directed upward.
The liquid ejected by the liquid ejecting head 62 is not limited to ink, and may be, for example, a liquid material obtained by dispersing or mixing particles of a functional material in a liquid. For example, the liquid ejecting head 62 may be configured to eject a liquid material containing, in a dispersed or dissolved form, a material such as an electrode material or a color material (pixel material) used for manufacturing a liquid crystal Display, an organic EL (Electro Luminescence) Display, or a Field Emission Display (FED).
The medium M is not limited to paper, and may be a plastic film or a thin plate material, or may be a fabric used in a printing apparatus or the like. The medium M may be clothes having any shape such as T-shirts, or may be a three-dimensional object having any shape such as tableware or stationery.
