Abstract:
According to one embodiment, a driving device includes a head driver configured to generate and apply a driving signal to an actuator for ejecting a liquid from a pressure chamber connected to a nozzle, the driving signal including a contraction pulse, the contraction pulse causing the actuator to contract a volume of the pressure chamber, and end application of the contraction pulse when a flow rate of the liquid from the nozzle has a negative value in a liquid ejection direction from the nozzle.

Claim (Index 6):
The driving device according to  claim 5 , wherein a pulse length of the contraction pulse is greater than the half time of the inherent oscillation period of the liquid and less than the inherent oscillation period of the liquid.
