PROBLEM TO BE SOLVED: To quickly and surely discharge a gas in a liquid supply channel to a gas discharge channel while inhibiting the gas in the gas discharge channel from flowing reversely into the liquid supply channel. SOLUTION: The inkjet printer discharges bubbles collected in ink storage parts 50a-50d formed in sub tanks 7a-7d which store the ink supplied to an inkjet head 6, by sucking by a suction pump from a gas discharge hole 42. At this time, a gas permeation film 45 with a bending part 45b is prepared between the ink storage parts 50a-50d and the gas discharge hole 42. A gas permeation film 57 discharges only the bubbles while preventing the ink from being discharged at the time of the suction action. Also the top surface of the gas permeation film 45 is filled with an oil 49. The gas permeation film 45 is sucked by the suction pump, thereby being displaced upward. COPYRIGHT: (C)2009,JPO&INPIT |
