摘要： In order to preserve good droplet discharge efficiency in a droplet discharge device, a plurality of timings are set within a period in which a plurality of droplets are to be discharged to a target position. Consecutive timings are divided by a cycle time of pressure wave that is generated inside a pressure chamber by transmitting a signal to an actuator. When a plurality of signals are applied to the actuator at consecutive timings, the peak of the pressure wave and the application of the signals are synchronous, and the droplet discharge efficiency will be improved. However, the consecutive number of timings at which the consecutive signals are transmitted is limited to a predetermined number. In this way, the pressure inside the pressure chamber can be prevented from becoming too high.

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.
