<p>A volume of an ink-deliver chamber is efficiently utilized to damp the change of pressure of an ink present in the chamber, and air bubbles produced in the chamber are prevented from flowing into an ink-jet recording head. In addition, an ink-jet recording apparatus having a plurality of ink-deliver chambers in a small space, is provided. Two ink cases are stacked on each other, and each of the two ink cases has, in opposite surfaces thereof, two ink-deliver chambers, respectively, that accommodate different inks. Respective open sides of the four ink-deliver chambers are closed by respective flexible films. A yellow-ink deliver chamber 41 as one of the four ink-deliver chambers has an ink-flow inlet 41b through which a yellow ink is introduced, and an ink-flow outlet 41c through which the yellow ink flow into an ink-deliver passage 91Y communicating with the ink-jet recording head, and the ink-flow inlet and outlet are provided at respective positions that are substantially most distant from each other such that almost all portions of an inner space of the yellow-ink deliver chamber, where the ink flows, are located between the ink-flow inlet and outlet.</p> |
