[0085] like Figure 17 and Figure 18 As shown, in this embodiment, the upper surface / top surface 11a includes a main surface 11a4 and a second operating surface 11a5. At least a portion of the main surface 11a4 and at least a portion of the second operating surface 11a5 are located in the same plane. In the front-back direction, at least a portion of the second operating surface 11a5 is located behind the main surface 11a4. Unlike Embodiment 1 and Embodiment 2, in this embodiment, the upper surface / top surface 11a is preferably an inclined plane. Specifically, as shown in the figure, a dashed line Y1 is drawn along a direction parallel to the front-back direction. In the vertical direction, the distance from the upper surface / top surface 11a to the dashed line Y1 gradually increases from front to back. In other words, when viewed from left to right in the left-right direction, there is an angle Q1 between the upper surface / top surface 11a and the dashed line Y1. Alternatively, with the lower surface 11b parallel to the front-back direction as a reference, in the vertical direction, the distance from the upper surface / top surface 11a to the lower surface 11b gradually decreases from front to back.

[0086] In some embodiments, the upper surface / top surface 11a is preferably a plane inclined in another direction. Specifically, with the lower surface 11b parallel to the front-back direction as a reference, the distance between the upper surface / top surface 11a and the lower surface 11b gradually increases from front to back in the vertical direction.

[0087] As in Example 6, one end of the ink cartridge 10 can also be provided with the active portion 11g in this example.

Claims
