<P>PROBLEM TO BE SOLVED: To prevent supply insufficiency of a liquid in a part of pressure chambers by reducing a difference in flow resistance from a liquid supply port of a common liquid chamber to the pressure chamber among two or more pressure chambers as much as possible. <P>SOLUTION: Two manifolds 47 are provided to two or more pressure chambers 44 which constitute an array of a pressure chamber array 51, and the two manifolds 47 are equipped respectively with ink supply ports 52. Moreover, ends where the ink supply ports 52 are formed are reverse in position between the two manifolds 47. The longer the length of a channel for the ink to flow from the ink supply port 52 of one manifold 47 to the pressure chamber 44 is, the shorter the length of a channel for the ink to flow from the ink supply port 52 of the other manifold 47 to the pressure chamber 44 is made for each of the two or more pressure chambers 44. <P>COPYRIGHT: (C)2012,JPO&INPIT |
