<P>PROBLEM TO BE SOLVED: To prevent precipitation in a sub-tank provided in a channel for supplying liquid to an ejection head. <P>SOLUTION: Inside of a sub-tank is agitated using a planar agitation member. A plurality of through-holes are provided over one surface of the agitation member at substantially equal intervals. The liquid passes through the through-holes when the inside of the sub-tank is agitated, and liquid flow is generated uniformly at a plurality of positions in the sub-tank. Consequently, the inside of the sub-tank is fully agitated and the components in the liquid precipitated in the sub-tank are diffused in the whole sub-tank. <P>COPYRIGHT: (C)2012,JPO&INPIT |
