Abstract:
A driving signal generation circuit generates a main driving signal including, in each of driving periods, at least a first sub driving signal including a first driving pulse and a second driving pulse, and a second sub driving signal including a third driving pulse and provided before the first sub driving signal. A driving signal supply circuit includes a first dot generator supplying the first sub driving signal but not supplying the second sub driving signal to an actuator coupled with a vibration plate defining a portion of a pressure chamber, and a second dot generator supplying the first sub driving signal and the second sub driving signal to the actuator.

Claim (Index 1):
A liquid injection device, comprising:\n a liquid injection head that injects a liquid; and a controller that controls the liquid injection head; wherein: the liquid injection head includes:\n a case that includes a pressure chamber provided therein, the pressure chamber storing a liquid; \n a vibration plate provided in the case, the vibration plate defining a portion of the pressure chamber; \n an actuator coupled with the vibration plate, the actuator being deformed when supplied with an electric signal; and \n a nozzle provided in the case and in communication with the pressure chamber; \n the controller includes:\n a driving signal generation circuit that generates a main driving signal that includes, in each of driving periods, at least a first sub driving signal and a second sub driving signal, the first sub driving signal including one or at least two driving pulses, and the second sub driving signal including one or at least two driving pulses and provided before the first sub driving signal; and \n a driving signal supply circuit that supplies the actuator with a portion of, or an entirety of, the main driving signal generated by the driving signal generation circuit; and \n the driving signal supply circuit includes:\n a first dot generator that supplies the actuator with the first sub driving signal but does not supply the actuator with the second sub driving signal; and \n a second dot generator that supplies the actuator with the first sub driving signal and the second sub driving signal.
