Droplet Discharge Device And Method Of Driving The Same

A method of driving a droplet discharge device comprising:

• inputting an amount of liquid to be discharged to a target position;
• storing a plurality of sequential patterns of signals;
• selecting one of the sequential patterns depending the inputted amount;
• and
• transmitting signals according to the selected sequential pattern to an actuator for discharging droplets sequentially from the droplet discharge device toward the target position;
• wherein the sequential patterns of the signals are prepared by the following conditions:
• (1) the signals are transmitted sequentially at intervals, the interval being substantially equal to a product of an integer and a cycle time of a pressure wave generated within a pressure chamber by applying the signal to an actuator, wherein the integer is one or more;
• and
• (2) in a case that a number of the signals transmitted within the period is equal to or more than a predetermined number, at least one interval is substantially equal to a product of an integer and the cycle time, wherein the integer is two or more.
