<P>PROBLEM TO BE SOLVED: To provide a liquid ejecting device which can control a small variation among liquid ejecting heads of a flow rate of a liquid supplied to each liquid ejecting means during the ejection of the liquid, and can control a small variation of the pressure of the liquid of the liquid ejecting heads in a constitution in which each liquid ejecting head ejects the liquid while the liquid is circulated in a circulation passage via a plurality of the liquid ejecting heads from a tank. <P>SOLUTION: Inks are supplied to a plurality of recording heads 43 from a sub-tank 25 through a third ink supply pipe 47 when a fourth pump 50 is driven, and the inks are made to flow back from the recording heads 43 through an ink circulation pipe 55 to the sub-tank 25. The third ink supply pipe 47 has a thick common pipe 47b and a plurality of connecting pipes 48 branched in parallel from the common pipe 47b. The passage resistance R1 of the common pipe 47b, the passage resistance R2 of the connecting pipes 48 and the passage resistance R3 of the ink circulation pipe 55 have a relationship of R1<R3<R2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
