Abstract
An ink cartridge, including a casing, an ink container provided in the casing, an ink absorbing material provided in the casing, and an ink supply port in communication with the ink container to supply ink from the ink container to an outside of the case. An ink receiving port is provided in communication with the ink absorbing material and a projection from the casing adjacent the supply port prevents erroneous loading of the cartridge. The projection also allows an operator to quickly understand the inserting direction of the cartridge and allows the cartridge to be placed on a surface without ink from the cartridge contaminating the surface.
