摘要： The liquid discharge device of the present invention comprises a piezoelectric actuator 11 and a flow passage member 21. The piezoelectric actuator 11 has a plurality of driving electrodes 15 formed on a piezoelectric ceramic layer 14, and a plurality of piezoelectric displacement elements 16 disposed longitudinally and laterally with regularity. In the flow passage member 21, a plurality of liquid compressing chambers 23 are formed with liquid outlet orifices 22. The piezoelectric actuator 11 is placed on the flow passage member 21, so that the driving electrodes 15 correspond in position to the liquid compressing chambers 23. A plurality of piezoelectric displacement elements 16 are disposed longitudinally in N lines (N≧4) and have dot density of not less than 300 dpi in lateral direction. The ratio (B/A) of arrangement interval B between the driving electrodes 15 in longitudinal direction to arrangement interval A between the driving electrodes 15 in lateral direction is 0.95 to 1.5. The minimum distance D between the neighboring driving electrodes 15 is 0.15A or more, D≧0.15A. This can suppress cross talk.

摘要： An actuator unit is driven with a voltage pulse supplied from a driver IC. The actuator unit can take two states of a first state wherein the volume of a pressure chamber is V1, and a second state wherein the volume of the pressure chamber is V2 larger than V1. A state of the actuator unit changes from the first state to the second state and then to the first state again so that ink is ejected through a nozzle connected to one end of the pressure chamber. A pulse width Tw of the voltage pulse to be supplied to the actuator unit is shorter than a pulse width Tmax at which a maximum ejection speed of ink ejected from the nozzle is obtained. Thus, with simplifying a waveform of the voltage pulse, two of large and small ink droplets can be successively ejected in the order of the large and small ink droplets.

摘要： A controller of an ink jet head includes a waveform information storage section for storing waveform patterns concerning a plurality of types of drive signals capable of making positions of dots formed on print paper by ejecting ink from nozzles different from each other with respect to a predetermined direction orthogonal to a relative moving direction between the print paper and the ink jet head. The controller further includes a waveform selection section for selecting one drive signal from among the plurality of drive signals stored in the waveform information storage section so that the same type of drive signal is not selected n or more successive times (where n is a natural number of two or more) for each nozzle.
