1. liquid discharge device,Described liquid discharge device possesses:

  • Liquid discharging head, it has nozzle, the pressure generating chamber that is communicated with this nozzle and makes the liquid in this pressure generating chamber produce the components of stres of pressure oscillation, can discharge liquid from nozzle by the action of this components of stres;

    AndDrive signal generation unit, it produces repeatedly and comprises the driving signal of discharging driving pulse, this discharge driving pulse driving pressure producing component so that liquid discharge from nozzle,It is characterized in that,Described discharge driving pulse forms the impulse waveform that comprises following key element;

    the first pressure generating chamber expansion key element, and expansion is drawn in pressure generating chamber side with meniscus thereby it makes pressure generating chamber;

    Key element is shunk by pressure generating chamber, thereby it makes by the pressure generating chamber contraction after this first pressure generating chamber expansion key element expansion meniscus is gone out to discharging thruster;

    And the second pressure generating chamber expansion key element, thereby it makes and shrinks pressure generating chamber after key element is shunk by this pressure generating chamber and expand and once more meniscus is drawn in pressure generating chamber side,Described each pressure generating chamber expansion key element has a plurality of different potential change rates.
