Next, regarding the operation of the liquid supply unit 30 configured as described above, the carriage 24
A description will be given focusing on the case where the liquid container 28 is attached to and detached from the upper mounting portion 27 via the adapter 29.

As shown in FIG. 3, when the liquid container 28 is attached to the attachment portion 27 via the adapter 29, there are the following two types of attachment methods. That is, after the liquid container 28 is integrally assembled with the adapter 29 to form the liquid supply unit 30, the unit 29 is mounted in units, and only the adapter 29 is first mounted on the mounting portion 27 and then mounted. There is a method of separately attaching the liquid container 28 to the adapter 29. Although it can be mounted by any method, in the following, the former method of mounting in units will be described as an example.

When mounting in units, the liquid container 28 is first inserted into the adapter 29, and the liquid container 28 and the adapter 29 are combined. When the liquid container 28 is inserted into the adapter 29, the movable engagement member 56 is pressed against the second opposing wall portion 62 of the adapter 29 to be elastically deformed and displaced in the −X direction. At substantially the same time as the −X direction convex portion 57 of the liquid container 28 engages with the −X direction concave portion 67 of the adapter 29, the movable engagement member 56 returns to the + X direction by the elastic force, and the + X direction convex portion The portion 56a engages with the concave portion 66 on the + X direction side of the adapter. In this way, the assembly of the liquid container 28 to the adapter 29 is completed, and the liquid supply unit 30 is configured.

Next, the liquid supply unit 30 configured as described above is mounted on the mounting portion 27.
When the liquid supply unit 30 is attached to the attachment portion 27, the liquid supply unit 30 is held so that the end portion on the −X direction side is inclined to the −Z direction side, and the −X direction of the adapter 29 is held.
The direction-side protrusion 70 is moved obliquely downward so that the direction-side protrusion 70 is inserted into the hole-shaped −X direction side engaged portion 33 of the mounting portion 27 obliquely from above.

Then, from this state, the liquid supply unit 30 is rotated from the inclined posture to the horizontal posture with reference to the insertion position of the -X direction side protrusion 70 with respect to the -X direction side engaged portion 33. Then, in the liquid supply unit 30, the + X direction protrusion 69 of the adapter 29 comes into contact with the inclined portion 39 having a downward slope toward the −X direction below the axis 34 of the rotation lever 35 from above. When the liquid supply unit 30 is further rotated from that state to a horizontal posture, the + X direction-side protrusion 69 of the adapter 29 slides over the inclined portion 39 of the rotation lever 35 in the −Z direction. After that, the state returns to the state shown in FIG. 3, and the state is engaged with the + X direction side engaged portion 37 at the lower end of the rotation lever 35 from the −Z direction side.

On the other hand, on the −X direction side, the −X direction side protrusion 70 of the adapter 29 maintains the insertion state with respect to the −X direction side engaged portion 33. At this time, the liquid supply part 55 exposed from the opening 65 of the adapter 29 is connected to the liquid introduction part 43 provided on the bottom part 40 of the mounting part 27 from above. Further, the terminal of the circuit board 68 provided on the slope portion 64 of the adapter 29 comes in close contact with the electrical connection portion 42 provided on the slope portion 41 of the mounting portion 27 from above and is electrically connected. . In this way, the mounting of the liquid supply unit 30 to the mounting portion 27 is completed, and the liquid is supplied to the head 25 from the liquid supply portion 55 of the liquid container 28 via the liquid introducing portion 43 of the mounting portion 27. Become.

Then, in the liquid supply unit 30 mounted in this way, when vibration is applied, for example, when the carriage 24 is reciprocated, it moves in the direction in which the adapter 29 is removed from the mounting portion 27 (in this case, the + Z direction). try to. Then, as shown in FIG. 3, in the liquid supply unit 30, the −X direction side engaged portion 33 and the + X direction side engaged portion 37 of the mounting portion 27 are
Since the -X direction side protrusion 70 and the + X direction side protrusion 69 of the adapter 29 are in contact with each other from the -Z direction side, the movement in the direction to be removed from the mounting portion 27 is restricted.
In this regard, in the present embodiment, the mounting portion 27 can regulate the movement of the −X direction side protrusion 70 and the + X direction side protrusion 69 provided on the adapter 29 in the direction in which the adapter 29 is removed from the mounting portion 27. Functions as a first engaging portion that engages with a part of the first engaging portion.

Moreover, in this case, the adapter 29 of the liquid supply unit 30 is connected in the direction (X direction) intersecting the direction (+ Z direction) in which the adapter 29 is removed from the mounting portion 27 at the connection portion between the liquid introduction unit 43 and the liquid supply unit 55. The protrusions 69 and 70 constituting the first engaging portion are located at a position on the −X direction side (first position) and a position on the + X direction side (second position) sandwiched from both sides.
For this reason, the adapter 29 is attached to the attachment portion 27 with a good balance.

Further, the liquid container 28 also tends to move in the direction away from the adapter 29 (+ Z direction) when the vibration described above is applied. Then, as shown in FIG. 3, in the liquid supply unit 30, the + X direction side convex portion 56 a of the liquid container 28 contacts and engages with the + X direction side concave portion 66 of the adapter 29 from the −Z direction side. The liquid container 28 is restricted from moving away from the adapter 29. Further, on the −X direction side, the −X direction convex portion 5
7 maintains the insertion state with respect to the −X direction side recess 67, and therefore has a function of restricting the liquid container 28 when it is about to move in the + Z direction. In this respect, in the present embodiment, the −X direction convex portion 57 and the + X direction convex portion 56a provided on the liquid container 28 can be restricted from moving in a direction in which the liquid container 28 moves away from the adapter 29. Adapter 29
It functions as a second engagement portion that engages with a part of the first engagement portion.

In addition, in this case, the liquid container 28 of the liquid supply unit 30 is a direction (+ Z direction) in which the liquid container 28 separates the connection portion between the liquid introduction part 43 and the liquid supply part 55 from the adapter 29.
Convex portions 56a constituting the second engaging portion at a position (first position) on the −X direction side (first position) and a position (second position) on the + X direction side sandwiched from both sides in the direction (X direction) intersecting , 57 are located. Therefore, the liquid container 28 is assembled to the adapter 29 with a good balance.

When the liquid in the liquid container 28 is low, the liquid container 28 is removed from the mounting portion 27.
May be taken out and replaced with a new liquid container 28. From the mounting portion 27 to the liquid container 28
In the case of taking out only the first portion, first, the upper end portion (the end portion on the + Z direction side) of the movable engagement member 56 is set to -X
The engagement between the + X direction side convex portion 56a and the + X direction side concave portion 66 of the adapter 29 is released. In this state, the liquid container 28 can be taken out by removing the −X direction convex portion 57 from the −X direction concave portion 67 of the adapter 29. And the new liquid container 28 is
If the adapter 29 is attached, the exchange of the liquid container 28 is completed.

According to the first embodiment, the following effects can be obtained.
(1) The second engagement portion (the −X direction convex portion 57, the + X direction convex portion 56a) is the adapter 29.
The liquid container 28 is fixed so as not to be separated from the adapter 29 by engaging with a part of the (-X direction side recess 67, + X direction side recess 66). In addition, the first engaging portion (−X direction side protrusion 70, + X direction side protrusion 69) is a part of the mounting portion 27 (−X direction side engaged portion 33, + X direction side engaged portion 37). By engaging, the adapter 29 is fixed so as not to be detached from the mounting portion 27. Therefore, even when vibration is applied to the liquid container 28 attached to the attachment part 27 via the adapter 29, the liquid supply part 55 and the attachment part 2 of the liquid container 28 are provided.
The possibility that liquid leaks from the connection portion with the liquid introducing portion 43 of 7 can be reduced.

(2) Second engagement portion (+ X direction convex portion 5) urged from the engagement release position toward the engagement position
The liquid container 28 can be firmly fixed to the adapter 29 by 6a). On the other hand, the second engaging portion (+ X direction convex portion 56 a) in the engaging position is moved to the −X direction side disengaging position against the urging force based on the elastic deformation of the movable engaging member 56. If the liquid container 28 is displaced, the liquid container 28 can be easily detached from the adapter 29 when the liquid container 28 is replaced.
