ABSTRACT:
A liquid jetting device includes a plurality of nozzles provided in a liquid jetting head, a charge-discharge actuator provided in correspondence with each nozzle, and a driving section for applying a driving signal to the charge-discharge actuator to jet liquid from the corresponding nozzle. The liquid jetting device includes a driving wave-form signal generating section configured to generate a driving wave-form signal as a basis of a signal for controlling a drive state of the actuator. A driving signal generating section is configured to amplify the driving wave-form signal generated by the driving wave-form signal generating section using a charge-use transistor and a discharge-use transistor connected in a push-pull configuration, and output a driving signal.
