An ink cartridge includes a first signal blocking portion, and a second signal blocking portion, in which a first plane intersects each of the first signal blocking portion and the second signal blocking portion. The ink cartridge also includes a third signal blocking portion, in which a second plane intersects each of the second signal blocking portion and the third signal blocking portion. Moreover, the second plane is perpendicular to the first plane, and the first signal blocking portion and the second signal blocking portion are aligned in a particular direction which is perpendicular to the second plane, and the second signal blocking portion and the third signal blocking portion are unaligned in the particular direction. In addition, each of the first signal blocking portion, the second signal blocking portion, and the third signal blocking portion are configured to either prevent a signal from passing therethrough or to alter a path of the signal.
