摘要： A piezoelectric actuator is deformed from an initial condition for a time (T1) in a direction, in which an inner volume of an ink chamber is increased, to supply ink to the ink chamber. Subsequently, the piezoelectric actuator is deformed for a time (T2) at a considerably slow speed as compared with the time (T1) for the preceding supply of ink to gradually increase the inner volume of the ink chamber to supply ink to the ink chamber. During the time (T2), free oscillation having generated in ink in the piezoelectric actuator and the ink chamber attenuates. Subsequently, the piezoelectric actuator is rapidly deformed to compress the ink chamber, thereby jetting ink in the ink chamber via nozzle holes.

A diaphragm (115) is bonded to the upper end surface of the laminated piezoelectric actuator unit, and a flow path plate (118) is bonded to the upper surface of the diaphragm (115). Here, a plurality of pressurizing chambers (116) and an ink flow path (117) are formed in the flow path plate (118) such that each pressurizing chamber (116) is disposed corresponding to each laminated piezoelectric actuator (111). Moreover, a nozzle plate (120) having nozzle holes (119) is connected to the upper surface of the flow path plate (118). Each laminated piezoelectric actuator (111) is deformed in the direction of thickness by applying voltage thereto for ejecting ink inside each pressurizing chamber (116) via each nozzle hole (119) in a direction perpendicular to the base plate (110).
