<P>PROBLEM TO BE SOLVED: To easily secure capacity for flowing air bubbles off from a filter according to an environmental change. <P>SOLUTION: A main flow passage M through which ink flows when foreign matter stored upstream of a filter 72 is removed and a sub flow passage S branched from the main flow passage M are formed in a head 1. A plurality of extension parts 26b are formed in the sub flow passage S and a pressure loss is configured to increase compared with the main flow passage M and a ratio of the flow rate of the main flow passage M to the flow rate of the sub flow passage S is configured to increase when flow rate of the ink increases. <P>COPYRIGHT: (C)2012,JPO&INPIT |
