Abstract

PURPOSE:To prevent air bubbles mingling in an ink from staying in an ink path. CONSTITUTION:Air holes 6, 10, 14 of plates 4, 8, 12 are formed to be sequentially shifted outward from a front end of a pressure chamber 17 so as to connect the pressure chamber 17 with a nozzle 2. An ink path from the pressure chamber 17 to the nozzle 2 is moderately curved, so that the ink flows smoothly, and at the same time, air bubbles mixed in the ink are prevented from staying in the path.
