Abstract (en)

An ink-jet printer comprising: a plurality of ink cartridges (11) formed as pillar-shaped ink tanks integrated with one another by a retention mechanism; and a recording head (16) ejecting color inks supplied from the ink cartridges (11). Since each of the ink tanks corresponding to each of colors can be individually replaced with a new ink tank, only the depleted ink tank can be replaced to improve the economical efficiency. Further, the incorporation of the plurality of the ink tanks enables the whole ink cartridge (11) more compact. <IMAGE>
