Abstract

PURPOSE: To lower the power voltage and then reduce the power consumption by connecting the signal to be applied to one of the electrodes holding the electro- mechanical coversion element between to the one input of the exclusive logic sum circuit of the opposing electrodes and then carrying out the phase control for the square wave signal to be applied.
CONSTITUTION: The voltage is applied to the piezoelectric room via the electro- mechanical conversion element featuring the accumulation effect. Then the ink is jetted through the nozzle linking to the piezoelectric room to drive the printer. In this case, voltage 13 plus input signal 15 are connected to common electrode 16 of the conversion element via driving circuit 14. At the same time, input signals 27W31 are applied to opposing electrodes 17W21 via drivers 22W26 along with application of the printing cycle of one dot in division of signals 27W31. Then the phase control is given to signals 27W31 to be supplied to electrodes 17W21, and voltage 13 to be applied to electrodes 16 plus 17W21 is set half of the ink jet voltage of the piezoelectric element. Thus the easiness of the boosting current is increased to reduce both the power consumption and the voltage to be used by the component parts.
