ABSTRACT:
An ink cartridge includes a case, an ink supply portion positioned at the case, an air intake portion positioned at the case, and a movable member configured to move between a first position and a second position relative to the case. The ink cartridge also includes a resilient member having a first end which is coupled to the case and a second end which is coupled to the movable member. Moreover, the resilient member is configured to expand in an expansion direction and to contract in a contraction direction opposite the expansion direction to move the movable member relative to the case between the first position and the second position, and a shape of the case in the expansion and contraction directions is unaltered when the resilient member expands and contracts. In addition, the entire moveable member is configured to substantially simultaneously move in a first direction relative to the case when the resilient member expands, and the entire moveable member is configured to substantially simultaneously move in a second direction opposite the first direction when the resilient member contracts.
