<P>PROBLEM TO BE SOLVED: To avoid the clogging of a jet head caused by the generation of air bubbles in a halfway flow passage or the like when a liquid is supplied from a liquid tank to the jet head. <P>SOLUTION: The liquid tank including a first liquid storage chamber and a second liquid storage chamber in which a liquid inflows from the first liquid storage chamber through a communication passage and which is connected to the jet head and varies in capacity is provided with a restrictor at a place where the communication passage is opened to the first liquid storage chamber. When the second liquid storage chamber increases in capacity, negative pressure is generated at the place of the restrictor, and thereby, air in the liquid becomes a bubble. Thereby, the deaerated liquid flows in the second liquid storage chamber, and then, supplied to the jet head. Also, the air bubble rises in the first liquid storage chamber by buoyancy, and thereby, does not flow out to a downstream side. Thereby avoiding the clogging of the jet head caused by the air bubbles. <P>COPYRIGHT: (C)2013,JPO&INPIT |
