Abstract

PURPOSE:To provide an ink jetting head characterized in that the continuous formation of ink particles is stabilized since the voltages generated by two cylindrical electric-distortion ocillators are applied to the ink present in a nozzle communicating to an ink chamber made of the vibrators and the decrease of recording speed is prevented. CONSTITUTION:A proper potential is given to a conductive pin 20 by providing earth for example thereon, and voltage pulses with the same polarity as earth are simultaneously impressed to the electrodes 16a and 16b of electric distortion oscillators 13 and 16. Thus, the oscillators 13 is recessed inwardly, and the oscillator 16 is swollen outwardly. Thereby, an ink chamber 18 shrinks, strong pressure is applied to the ink present therein, and ink particles are jetted from a nozzle 15a at a high speed. In case ink is used for recording on on-demand basis, therefore, same- polarity voltage pulses are applied to the electrodes 13a and 16b when picture signal represents printing.
