  The hinge 26 is disposed on the upper back of the housing 21. The hinge 26 rotates the reading device 12 relative to the housing 21 around a rotation axis extending in the scanning direction X. Specifically, the hinge 26 opens the “first position” where the reading device 12 covers the upper opening 212 of the housing 21 as shown in FIG. 1 and the opening 212 of the housing 21 as shown in FIG. The reader 12 is rotated between the “second position”.

Next, the internal configuration of the liquid ejecting apparatus 11 will be described with reference to FIGS. 3 and 4.
As shown in FIG. 4, the feeding unit 30 includes a pickup roller 31 that feeds the uppermost medium M among the plurality of media M stacked on the medium storage unit 22 toward the transport unit 40. The pickup roller 31 is urged downward toward the medium M stacked on the medium accommodation unit 22.

  As shown in FIG. 4, the transport unit 40 includes a first transport roller 41 and a first driven roller 42 that are disposed behind the support unit 50, and a second transport roller 43 and a second transport roller that are disposed in front of the support unit 50. 2 driven rollers 44. The first transport roller 41 and the second transport roller 43 are disposed below the transport path FP of the medium M, and the first driven roller 42 and the second driven roller 44 are disposed above the transport path FP of the medium M. . The transport unit 40 rotates the transport rollers 41 and 43 with the medium M fed from the feed unit 30 sandwiched between the transport rollers 41 and 43 and the driven rollers 42 and 44. Thus, the transport unit 40 transports the medium M toward the support unit 50. Note that the second transport roller 43 and the second driven roller 44 disposed in front of the support unit 50 may be a pressing mechanism that suppresses the medium M from being lifted.

  As shown in FIGS. 3 and 4, the support portion 50 has a rectangular plate shape in which the scanning direction X is the longitudinal direction and the depth direction Y is the short direction. The support unit 50 is disposed below the liquid ejecting unit 60 and constitutes a part of the transport path FP of the medium M. The support unit 50 may have a configuration for sucking and adsorbing the medium M in order to stabilize the posture of the medium M to be supported.

  Here, in the liquid ejecting apparatus 11 according to the present embodiment, the “conveyance path FP” that is the path of the medium M from the medium accommodating unit 22 to the discharge port 211 is reversed in the depth direction Y. That is, the medium M stored in the medium storage unit 22 moves rearward by the feeding unit 30, and the medium M on the support unit 50 moves forward by the transport unit 40. In the following description, the moving direction of the medium M transported on the support unit 50 by the transport unit 40 is referred to as “transport direction F”. That is, the upstream side in the transport direction F is the rear side of the liquid ejecting apparatus 11, and the downstream side in the transport direction F is the front side of the liquid ejecting apparatus 11.

  As shown in FIGS. 3 and 4, the liquid ejecting unit 60 includes a liquid ejecting head 62 having a nozzle 61 for ejecting liquid, a carriage 63 on which the liquid ejecting head 62 is mounted, and a scanning direction X of the carriage 63. A guide shaft 64 that guides the movement, and a supply flow path 65 that connects the liquid ejecting head 62 and the liquid container 23 are provided.

  The liquid ejecting head 62 is mounted on the carriage 63 so that the opening surface where the nozzle 61 opens is directed toward the support portion 50. The carriage 63 is disposed above the transport path FP (support unit 50). The carriage 63 can be reciprocated in the scanning direction X by a moving mechanism (not shown). The supply channel 65 is an elastic tube that can be deformed as the carriage 63 moves. The supply flow path 65 is disposed between the carriage 63 and the holding unit 90 in the transport 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 that passes when the carriage 63 moves in the scanning direction X is also referred to as a “movement path”. In addition, a position where the liquid ejecting head 62 mounted on the carriage 63 faces the support portion 50 in the movement path is also referred to as an “ejection position”. The ejection position is the position of the carriage 63 when the liquid ejection head 62 can eject 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 transport direction F. That is, the maintenance device 70 is disposed at a position adjacent to the support unit 50 in the scanning direction X. The maintenance device 70 includes a cap 71 that opens upward, a waste liquid channel 72 that has an upstream end connected to the cap 71, a suction unit 73 that is provided in the middle of the waste liquid channel 72, and an opening surface of the liquid ejecting head 62. A wiping member 74 that can be wiped off, a slider 75 that holds the cap 71, and a base 76 that supports the slider 75 so as to be relatively movable are provided. The suction unit 73 is configured to perform a suction operation for sucking the inside of the cap 71. The slider 75 has an engaging protrusion 751 protruding upward at a first end X1 in the scanning direction X.

  In the maintenance device 70, when the carriage 63 that moves toward the first end X <b> 1 engages with the engagement protrusion 751, the slider 75 moves obliquely upward as the carriage 63 moves. As a result, the cap 71 comes into contact with the opening surface of the liquid ejecting head 62, and the space where the nozzle 61 opens is a closed space. The operation in which the cap 71 forms a closed space in this way is called “capping”. In FIG. 3, the positions of the cap 71 and the slider 75 at the time of capping are indicated by two-dot chain lines.

  In addition, the position of the carriage 63 when the liquid ejecting head 62 mounted on the carriage 63 faces the maintenance device 70 in the movement path is also referred to as “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 near the first end X1 in the scanning direction X of the movement path of the carriage 63.

  When the suction unit 73 is driven during capping, the inside of the liquid ejecting head 62 is sucked through the nozzle 61. Thus, the operation in which the suction unit 73 performs suction through the nozzle 61 and sucks the liquid in the liquid ejecting head 62 is referred to as “suction cleaning”. In the present embodiment, an example of a “suction mechanism” is configured including the cap 71 and the suction unit 73.

  As illustrated in FIG. 3, the holding unit 90 is disposed above the transport path FP and the discharge port 211 (medium storage unit 22) in the vertical direction Z. The holding unit 90 is disposed on the downstream side of the movement path of the carriage 63 and on the upstream side of the operation unit 25 in the transport direction F. The holding unit 90 can be electrically connected to the holder 91 that holds the waste liquid container 80 that can store the waste liquid generated by suction cleaning, the connection part 92 that communicates with the downstream end of the waste liquid channel 72, and the waste liquid container 80. Board connecting portion 93.

  The holder 91 includes a first wall portion 911 and a second wall portion 912 that are arranged at intervals in the transport direction F, and a third wall portion that connects the first wall portion 911 and the second wall portion 912 in the transport direction F. 913 and a fourth wall portion 914. The first wall portion 911 is disposed on the upstream side in the transport direction F, and the second wall portion 912 is disposed on the downstream side in the transport direction F. The third wall portion 913 connects the first ends X1 of the first wall portion 911 and the second wall portion 912 in the scanning direction X to each other. The fourth wall portion 914 connects the lower ends of the first wall portion 911 and the second wall portion 912. Thus, the first wall portion 911, the second wall portion 912, and the third wall portion 913 constitute the side wall of the holder 91, and the fourth wall portion 914 constitutes the bottom wall of the holder 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 are the fourth wall. The length may be approximately the same as the 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 in 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 transport direction F. In other words, the connecting portion 92 is provided at a position closer to the upstream end than the downstream end in the transport direction F of the holding portion 90 (holder 91). The connecting portion 92 is inserted into the waste liquid container 80 to introduce the waste liquid supplied from the maintenance device 70 into the waste liquid container 80.

  The board connecting portion 93 is provided in the second wall portion 912 so that the electrical contact faces the first wall portion 911. That is, the board connecting portion 93 is provided on the second wall portion 912 near the operation portion 25 in 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 that stores waste liquid (for example, waste ink) discharged by the suction operation of the maintenance device 70. It is preferable to arrange an absorber capable of absorbing the waste liquid inside the waste liquid container 80.

  An introduction portion 81 to which the connection portion 92 is connected is provided on the side surface that intersects the longitudinal direction of the waste liquid container 80. The introduction part 81 is preferably sealed with an O-ring or the like so that the waste liquid does not leak when the connection part 92 is inserted and removed.

  A circuit board 82 connected to the board connecting part 93 of the holding part 90 is provided on a side surface extending in the longitudinal direction of the waste liquid container 80. The circuit board 82 is a thin plate-like IC chip and is provided so that the electrical contacts face outward. For example, the circuit board 82 may store in advance information related to the specifications of the waste liquid container 80, or may sequentially store the amount of waste liquid stored in the waste liquid container 80. That is, the liquid ejecting apparatus 11 can determine whether or not the waste liquid container 80 attached to the holding unit 90 is an appropriate waste liquid container 80 based on the information stored in the circuit board 82.

  When the waste liquid container 80 is moved in the direction from the second end X2 in the scanning direction X toward the first end X1 with respect to the holding unit 90, the waste liquid container 80 is attached to the holding unit 90. That is, the introduction part 81 and the connection part 92 are connected, and the tip of the connection part 92 is located inside the waste liquid container 80. In addition, the circuit board 82 is connected to the board connecting portion 93, and the liquid ejecting apparatus 11 can obtain information on the waste liquid container 80. On the other hand, when the waste liquid container 80 is moved in the direction from the first end X1 in the scanning direction X toward the second end X2 with respect to the holding unit 90, the waste liquid container 80 is removed from the holding unit 90. Thus, the holding unit 90 holds the waste liquid container 80 in a detachable manner.

  The holding unit 90 and the waste liquid container 80 are preferably provided with a structure for defining the mounting relationship of the waste liquid container 80 with respect to the holding unit 90. For example, by providing a concave portion in one of the holding unit 90 and the waste liquid container 80 and providing a convex portion in the other, the waste liquid container 80 is mounted on the holding unit 90 in the direction different from the original in the vertical direction Z. This may be prevented.

  As shown in FIGS. 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. The document table 121 is formed of a glass plate that transmits light at least at a portion where the document is placed. An image scanner (not shown) that reads a document placed on the document table 121 is provided below the document table 121. The document cover 122 is rotated relative to the document table 121 by the hinge 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 reading device 12 rotates with respect to the liquid ejecting device 11 between the first position that covers the opening 212 of the housing 21 and the second position that opens the opening 212 of the housing 21. To do. That is, in the present embodiment, the reading device 12 corresponds to an example of a “cover” in that the opening 212 of the housing 21 is opened and closed. As shown in FIG. 2, when the reading device 12 is disposed at the second position, the holding unit 90 and the waste liquid container 80 attached to the holding unit 90 are exposed through the opening 212 of the housing 21. To do.

Next, the operation of the liquid ejecting apparatus 11 of this 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. Subsequently, the user moves the used waste container 80 in the direction from the first end X1 to the second end X2 in the scanning direction X. Thus, the used waste liquid container 80 is removed from the holding unit 90. Thereafter, the user moves in a direction from the second end X2 to the first end X1 in the scanning direction X in a state where the unused waste liquid container 80 is housed in the holder 91 of the holding unit 90, as shown in FIG. Let Then, the waste liquid container 80 is attached to the holding unit 90. Thus, according to the present embodiment, since the holding unit 90 for mounting the waste liquid container 80 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 mentioned here refers to exchanging the waste liquid container 80, confirming whether the waste liquid container 80 can normally store the waste liquid, or confirming the amount of waste liquid stored in the waste liquid container 80. Say work.

According to the embodiment described above, the following effects can be obtained.
(1) The holding unit 90 is disposed above the transport path FP of the medium M and downstream (front) in the transport direction F from the movement path of the carriage 63. Therefore, the user of the liquid ejecting apparatus 11 can easily access the waste liquid container 80 from above the liquid ejecting apparatus 11 and the downstream side in the transport direction F. As a result, the maintainability of the waste liquid container 80 is improved.

  (2) The waste liquid container 80 is held by the holding unit 90 above the discharge port 211 for the medium M. For this reason, the maintainability of the waste liquid container 80 becomes better. Further, when the medium M is clogged in the vicinity of the discharge port 211 of the transport path FP, the clogging of the medium M can be eliminated without being obstructed by the waste liquid container 80.

  (3) Since the waste liquid container 80 can be disposed in a region that tends to be a dead space between the movement path of the carriage 63 and the operation unit 25, the liquid ejecting apparatus 11 can be prevented from being enlarged. Further, the area between the movement path and the operation unit 25 tends to be a long area in the scanning direction X, and the length of the waste liquid container 80 in the longitudinal direction can be made close to the movement path. That is, it becomes easy to increase the capacity of the waste liquid container 80.

  (4) Since the connecting portion 92 is provided at a position near the first end X1 in the scanning direction X of the holding portion 90, the cap 71 (suction mechanism) and The distance between the connection portion 92 is shortened. That is, the waste liquid flow path 72 from the cap 71 to the connection portion 92 is shortened, and the risk of waste liquid leakage can be reduced. In addition, the maintainability of the waste liquid channel 72 can be improved.

  (5) By extending the connecting part 92 in the scanning direction X, the waste liquid container 80 and the connecting part 92 are moved by moving the waste liquid container 80 in the direction opposite to the extending direction of the connecting part 92. Can connect. Further, as compared with the case where the connecting portion 92 extends in the vertical direction Z, the waste liquid is less likely to leak downward from the connecting portion 92 or the waste liquid container 80 when the waste liquid container 80 is attached or detached.

  (6) Since the connecting portion 92 is provided at a position near the moving path of the holding portion 90 in the transport direction F, the connecting portion 92 is separated from the operating portion 25 as compared with the case where it is provided near the operating portion 25. Placed in a different position. For this reason, even if a liquid leaks from the connection part 92, it can suppress that such a liquid reaches | attains the electric system of the operation part 25. FIG.

  (7) By providing the board connecting portion 93 at a position near the operation section 25 of the holding section 90 in the transport direction F, the distance between the board connecting section 93 and the operation section 25 is shortened. As a result, electrical wiring for the operation unit 25 and the board connection unit 93 can be performed collectively. In addition, the maintainability of the wiring is improved.

  (8) The multifunction machine 10 includes the reading device 12 that rotates between the first position and the second position. For this reason, when the reading device 12 is arranged at the first position, the constituent members in the housing 21 can be protected. On the other hand, when the reading device 12 is arranged at the second position, the waste liquid container 80 exposed through the opening 212 can be maintained.

  (9) The reading device 12 rotates around a hinge 26 provided behind the liquid ejecting device 11. For this reason, the front of the liquid ejecting apparatus 11 is largely opened by disposing the reading device 12 at the second position. Therefore, the maintainability of the waste liquid container 80 disposed on the front side of the liquid ejecting apparatus 11 becomes better.

In addition, you may change the said embodiment as shown below.
The liquid ejecting apparatus 11 may include a liquid receiving unit that receives liquid ejected periodically 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 store the liquid (waste liquid) received by the liquid receiving unit.

The holding unit 90 may not include the board connecting unit 93. In this case, the waste liquid container 80 may not include the circuit board 82.
The multifunction device 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 with respect to the housing 21, or may open and close the opening 212 by sliding with respect to the housing 21.

  The mounting direction of the waste liquid container 80 with respect to the holding unit 90 may not be the scanning direction X.
