As described above, the ink storage bodies 28 of the respective colors attached to the mounting portions 32 a and 32 b in the storage units 18 a and 18 b and the carriage 22 having the recording head 20 are connected to the ink tube 30 and the ink tube via the ink relay portion 29. 31, the ink of each color can be supplied to the recording head 20.

<About storage unit>
Next, the configuration of the storage unit 18a and the storage unit 18b described above will be described below.
First, the storage unit 18b provided on the left side as viewed from the front side of the apparatus main body 12, that is, on the side surface 13b (FIG. 5) on the −X side will be described with reference to FIGS.
The storage unit 18 b is an exterior cover 34 that forms the −X side surface 13 b of the apparatus main body 12.
It is attached to b so that attachment or detachment is possible.
As shown in FIG. 4, the storage unit 18b includes a storage case body 36b, a partition member 38b that divides the space in the storage case body 36b, and a case cover 40b that opens and closes the storage unit 18b. In FIG. 4, the ink container 28 and the ink tube 30b are omitted.

As described above, the black ink container 28 is accommodated in the storage unit 18b (FIG. 6). Normally (when the printer 10 is used or not used), the storage unit 18b
The case cover 40b is closed (FIG. 5), and the case cover 40b is opened when the ink container 28 is exchanged or when maintenance inside the apparatus main body 12 is performed.

The case cover 40b that opens and closes includes a hinge portion 41, and is configured to open and close the storage case body 36b. The case cover 40b can be removed from the storage case main body 36b by removing a screw (not shown) that connects the hinge portion 41 and the case cover 40b.

4 and 10, the storage case main body 36b has a mounting portion 32 for the ink storage body 28.
b is provided. Further, in the storage case main body 36b, the side surface 13b of the apparatus main body 12 is used.
A tube insertion portion 42b is formed on the surface facing the exterior cover 34b constituting the.
Further, on the exterior cover 34b of the apparatus main body 12, a main body side tube insertion portion 44b (FIG. 4) leading to the inside of the apparatus main body 12 at a position corresponding to the tube insertion portion 42b of the storage case main body 36b.
Is provided.

As shown in FIG. 10, an ink tube 30b corresponding to black ink extends from below the attachment portion 32b of the ink container 28 to the tube insertion portion 42b across the storage unit 18b, and the ink tube 30b is inserted into the tube. Portion 42b and main body side tube insertion portion 4
It is guided into the apparatus main body 12 through 4b (FIG. 4).

In the storage unit 18b, an ink storage portion 46b (first space: see FIGS. 3 and 4) for storing the ink storage body 28 and a device main body 12 side with respect to the ink storage portion 46b by a partition member 38b. It is divided into a tube storage portion 48b (second space: see FIGS. 3 and 4) that is positioned and stores the ink tube 30b.
The case cover 40b is configured to open and close the ink storage portion 46b. The space between the case cover 40b and the partition member 38 shown in FIG. 4 serves as the ink storage portion 46b, and the exterior cover in the partition member 38 and the storage case body 36b. The space between the surface facing 34b is the tube storage portion 48b.

The attachment portion 32b of the ink container 28 is exposed in the ink storage portion 46b (FIGS. 3 and 6), and the ink tube 30b drawn from below the attachment portion 32b is connected to the tube storage portion 48b (FIG. 3) It is designed to fit within. Therefore, when the case cover 40b is opened (for example, FIG. 7), the ink tube 30b is hidden.
With this configuration, for example, when the case cover 40b is opened at the time of replacing the ink container 28, the possibility that the user touches the ink tube 30b can be reduced. In addition, since at least a part of the drawn ink tube 30b can be hidden by the partition member 38, the appearance can be improved.

Here, the storage unit 18b includes a first opening 50 and a second opening 52 that are accessible from the storage unit 18b into the apparatus main body 12 (FIG. 8). In this embodiment, the apparatus main body 12 can be accessed from the ink storage portion 46b. Specific configurations of the first opening 50 and the second opening 52 will be described below.

Yes. The lock of the carriage 22 is configured to be released by moving the gear 60. That is, the gear 60 is connected to the carriage 2.
This is for releasing the carriage lock that locks the movement 2. Accordingly, the second opening 52 is located in the storage unit 1 provided on the side surface of the apparatus main body 12 close to the home position.
8b.

Here, when the printer 10 is continuously used, maintenance such as component replacement is performed. At this time, as a component that is frequently replaced, the recording head 20 and components related to ink supply to the recording head 20 (ink relay) Part 29, ink tubes 30 and 31, and tube connecting part 33). Maintenance work such as parts replacement is for the safety of workers.
Usually, the printer 10 is turned off. At this time, when the above-described recording head 20 and the constituent members relating to the ink supply to the recording head 20 are replaced, the carriage 22
Therefore, it is necessary to unlock the carriage 22. Further, when the constituent members related to the recording head 20 are replaced, it is necessary to perform PG adjustment after the parts replacement operation.

In such a case, since the printer 10 includes the second opening 52 that can access the gear 60 in the apparatus main body 12 from within the storage unit 18b, maintenance can be performed without removing the storage unit 18b from the apparatus main body 12. The carriage 22 can be unlocked by manually rotating the gear 60 (including a case where a jig or the like is used in addition to direct contact with a hand). Further, since the cam mechanism 54 in the apparatus main body 12 is accessible from the first opening 50, the PG adjustment of the recording head 20 can be performed without removing the storage unit 18b from the apparatus main body 12. That is, the maintenance in the apparatus main body 12 can be easily performed from the storage unit 18b.

The gear 60 that can be operated from the second opening 52 is not limited to a gear that constitutes the carriage drive mechanism, and may be a gear of another component that operates by the gear. Further, the “operation unit” provided in the apparatus main body 12 is not limited to a gear, and may be a lever, a switch, or the like that operates other mechanisms provided in the apparatus main body 12.
