PROBLEM TO BE SOLVED: To enable to maintain the consistency of liquid taken out to a value close to the initial consistency even when contents of liquid to be stored such as pigments sediment with an elapse of time, and to enable the maintenance of the predetermined printing consistency by preventing consistency changes of the print material, even when a printing device is to be used over a long period of time. SOLUTION: A tube 107 prolonged into liquid enclosure from a liquid ejection section prepared on the bottom of a liquid enclosure 200 is formed, and liquid indraft orifices 107a-107g which lead to the inside of the liquid enclosure are formed in many positions in vertical direction. Among the many liquid indraft orifices, the indraft resistance of the liquid indraft orifice 107a, which is positioned in a lower layer domain, is made larger than indraft resistance of other liquid indraft orifices. Or, the orifice size of the many liquid indraft orifices is designed so that the liquid indraft amount to the inside of the tube via each indraft orifice is equal. COPYRIGHT: (C)2005,JPO&NCIPI |
