LIQUID EJECTION HEAD, LIQUID EJECTING METHOD AND LIQUID EJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a novel liquid ejection principle by suppressing generated bubbles and liquid on the ejection opening side and the supply side through the structure of a movable member and the entire liquid channel. SOLUTION: When a displaced movable member 31 touches a stopper 64, a liquid channel 10 having a bubble generating region 11 provides a substantially closed space except an ejection opening 18 and suppression of bubbles is started under closed space state. In such a liquid ejection head, the movable member 31 is displayed by bubbles generated in the bubble generating region 11 while being displaced by a piezoelectric element 34 about a fulcrum part 33.
