<p>A plurality of ink cartridges are detachably attached to a cartridge holder of an inkjet printer and are aligned in parallel. Each ink cartridge includes a projection or a recess formed at a side of the ink cartridge that faces the adjacent ink cartridge. A set of the projection and the matching recess of each pair of adjacent ink cartridges forms a matching set in which the projection engages with the recess to position the ink cartridges with respect to each other. Each matching set has a different shape. Thus, when the ink cartridges are attached to the cartridge holder, the ink cartridges are connected together as aligned in a predetermined order. <IMAGE></p> |
