PROBLEM TO BE SOLVED: To provide a liquid jetting device capable of controlling jetting middle microvibration corresponding to the characteristics and the kind of the liquid. SOLUTION: This liquid jetting device comprises a head member 8 having a nozzle opening 51, and a pressure fluctuating means 35 for fluctuating the pressure of the liquid at the nozzle opening 51 part. A main signal generating means 11 produces an ejection driving signal, and a main mode signal generating means produces a main mode signal based on jetting data and a liquid supplied to the nozzle opening 51. A signal fusing part produces a driving pulse signal based on the AND of the ejection driving signal and the main mode signal, and a control main body part drives the pressure fluctuating means 35 based on the driving pulse signal. |
