ABSTRACT:
An ink cartridge includes a movable member which includes a sliding member and a float portion. The sliding member includes a signal blocking portion, and the signal blocking portion is configured to move in a first direction from a first position within a translucent portion to a second position based on the amount of ink within the ink chamber. Moreover, the float portion is operationally coupled to the sliding member, and the float portion is disposed within the ink chamber. The float portion is configured to move independent of the first portion in a second direction from a third position to a fourth position based on the amount of ink within the ink chamber. For example, the second direction may be substantially perpendicular to the first direction or may be slanted with respect to the first direction.
