<P>PROBLEM TO BE SOLVED: To suppress an increase in the number of parts of a liquid ejection apparatus, while keeping pressure in a plurality of ejection heads properly. <P>SOLUTION: A liquid in a liquid storage part is supplied to the plurality of ejection heads through a pressure adjusting valve to thereby share use of the pressure adjusting valve by the plurality of ejection heads. The pressure adjusting valve is configured to be opened by ejecting the liquid by the ejection heads thereby reducing the pressure on an ejection head side, so that the liquid ejected on the ejection head side is supplied from the liquid storage part. Thus, even when the pressure adjusting valve is not provided in each ejection head, the pressure in the plurality of ejection heads can be kept sufficiently properly, so that the number of installed pressure adjusting valves can be reduced to suppress the increase in the number of parts of the whole apparatus. <P>COPYRIGHT: (C)2012,JPO&INPIT |
