Filed: 2003-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To prevent bubbles from remaining by solving stagnation brought about by a constriction part set at an ink supply passage, and improving the discharge capability for the bubbles.  <P>SOLUTION: The constriction part 14A is set at a first common ink channel 14. In a process while ink is filled in the first common ink channel 14, the stagnation of slowing down a flow of the ink is brought about by effects of the constriction part 14A, and the bubbles tend to remain. If the bubbles move and flow into a pressure chamber 12, discharge characteristics of ink droplets are worsened, and non-discharge is brought about in the worst case. However, the stagnation is eliminated by arranging an opening part 20 of an ink supply channel 18 of each ejector 60 in the vicinity of the downstream side of the constriction part 14A. The discharge capability for the bubbles of the first common ink channel 14 is thus improved, and the bubbles are prevented from remaining. Worsening of the discharge characteristics of ink droplets or non-discharge which is caused by an entry of the bubbles remaining in the first common ink channel 14 into the ejector 60 is prevented accordingly.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
