PROBLEM TO BE SOLVED: To provide a fluid ejection device running by a compact pump.SOLUTION: A fluid ejection device 100 includes: a pulsation generation section 30 changing a volume of a fluid chamber and ejecting pulsation flow; a fluid supply section 10 supplying fluid to the pulsation generation section 30; a drive control section 50 inputting a driving signal to individual sections; and an operation command input section 40. A fluid supply driving signal driving the fluid supply section 10 for supplying the fluid to the pulsation generation section 30 and a pulsation flow driving signal driving volume change means for ejecting the fluid as pulsation flow are input in operative association with input of an operation command. More specifically, ejection and a stop of the fluid can be in the operative association with pulsation flow generation, a stop thereof and feeding water to a pump. Accordingly, necessary and sufficient continuous ejection can be obtained even when a fluid amount secured in the fluid supply section 10 is small and the pump is compact by causing the fluid supply driving signal and the pulsation flow driving signal to be in the operative association with each other and narrowing down the continuous ejection to a necessary and sufficient range. |
