  In the present embodiment, the handle 84 is rotatable with respect to the base member 91 in the ink container 51. Therefore, for example, as shown in FIG. 17, the protrusion amount of the handle 84 can be suppressed by rotating the handle 84 toward the ink containing portion 82. Thereby, the size of the ink container 51 can be reduced. Therefore, for example, when the ink container 51 is stored, the volume of the space required for storage can be reduced by rotating the handle 84 toward the ink container 82. Further, for example, if the handle 84 is rotated toward the ink storage portion 82 side, the volume in physical distribution can be easily reduced, so that the cost can be easily reduced.

  Further, as shown in FIG. 18, the rotation stop position of the handle 84 when the handle 84 is rotated toward the ink outlet 101 (when rotated in the second rotation direction R2) is the K1 direction. When viewed from the above, it is preferable that the handle 84 overlaps the ink lead-out portion 101 and the circuit board 105. At this position, for example, when the ink container 51 falls from a state where the ink container 51 is raised on the floor or the like with the Z-axis direction of the ink container 51 directed vertically upward, It is easy to avoid the circuit board 105 from colliding with the floor. That is, it is easy to protect the ink outlet 101 and the circuit board 105 with the handle 84.

  In the present embodiment, in the ink container 51, the engaging portion 155A and the engaging portion 155B of the handle 84 are slidable along the engaging groove 125. For this reason, as shown in FIG. 19, the handle 84 can be raised and lowered with respect to the base member 91. Thereby, for example, when the ink container 51 is stored, if the handle 84 is lowered to the ink storage part 82 side, the volume of the space required for storage can be reduced. On the other hand, when the ink container 51 is moved, if the handle 84 is raised (a two-dot chain line in the figure), the gap between the handle 84 and the base member 91 can be widened, so that it is easy to grip. Thus, the handle 84 can be raised and lowered according to the storage and movement of the ink container 51, which is convenient.

  In the present embodiment, the detachable unit 171 employs a configuration in which the holder 172 is fixed to the printer 3. For this reason, the movable member 177 is displaced in the detachable unit 171. However, the configuration of the detachable unit 171 is not limited to this. As the detachable unit 171, a configuration in which the movable member 177 is fixed to the printer 3 can be employed. In this configuration, the holder 172, the ink introduction part 173, and the contact mechanism 175 are displaced. That is, in the configuration in which the movable member 177 is fixed to the printer 3, when the handle 84 is rotated after the engaging portion 123 of the ink container 51 is supported by the support portion 183, as shown in FIG. The support member 181, the ink introduction part 173, and the contact mechanism 175 are displaced in the K1 direction. Also in this configuration, by rotating the handle 84, the ink lead-out part 101 and the ink introduction part 173 can be connected, and the connection between the ink lead-out part 101 and the ink introduction part 173 can be released.

  In the present embodiment, the receiving portion 203 is formed on the support portion 202, and the protruding portion 157 is formed on the handle 84. However, the configuration of the handle 84 and the support portion 202 is not limited to this. As the configuration of the handle 84 and the support portion 202, for example, a configuration in which the protrusion portion 157 is formed on the support portion 202 and the receiving portion 203 is formed on the handle 84 may be employed. In this configuration, the same effect can be obtained.

  In the present embodiment, the ink containing portion 82 is configured by joining the sheet member 82A, the sheet member 82B, and the sheet member 82C. However, the configuration of the ink containing portion 82 is not limited to this. As a configuration of the ink containing portion 82, for example, as shown in FIG. 20, a flexible container formed by blow molding may be employed. In this configuration, the same effect can be obtained.
