Patent ID: 8419148

Claim:
A liquid ejecting device comprising: a channel member formed with a liquid channel having an ejection port for ejecting droplets, the channel member having a surface formed with an opening through which a part of the liquid channel is exposed; an actuator including a layered body disposed on the surface of the channel member so as to confront the opening for applying energy to liquid in the opening, the layered body including a first piezoelectric layer and a second piezoelectric layer arranged from a side closer to the surface of the channel member in this order, each of the first and second piezoelectric layers including an active portion in a part in confrontation with the opening, the active portion being interposed between electrodes with respect to a thickness direction; a driving-signal generating section configured to generate driving signals for driving the actuator, the driving-signal generating section being configured to generate a first driving signal corresponding to a first voltage applied to the active portion of the first piezoelectric layer and a second driving signal corresponding to a second voltage applied to the active portion of the second piezoelectric layer; a voltage-set-information storing section that stores two or more kinds of voltage sets each including a combination of the first and second voltages for each number of droplets ejected from the ejection port within a single recording cycle, where the single recording cycle is a time period required for a recording medium to move relative to the channel member by a unit distance corresponding to a resolution of an image to be recorded on the recording medium; and a voltage applying section configured to apply the first voltage to the active portion of the first piezoelectric layer and to apply the second voltage to the active portion of the second piezoelectric layer based on image data of the image, the voltage applying section being configured to select one of the two or more kinds of voltage sets stored in the voltage-set-information storing section and to apply each voltage constituting the selected voltage set to the active portions of the first and second piezoelectric layers, wherein the voltage sets are classified by a degree of temporal overlapping of pulse-shaped voltages included in the first and second voltages.
