Abstract
A liquid cartridge includes a liquid supply port configured to provide communication between an interior and an exterior of the liquid cartridge, a first wall having the liquid supply port, and a second wall spaced from the first wall. A first storage chamber is between the first and second walls, and a second storage chamber is between the first and second walls communicating with both the liquid supply port and the first storage chamber. A prism is in the second storage chamber, and the prism has an inclined surface configured to change the state of received light in response to a level of liquid contained in the second storage chamber. The prism is positioned between the first and second walls and above the first storage chamber.
