Abstract

PURPOSE:To enable to perform a temperature compensation of an ink jet amount and jet speed in reaction to an ambient temperature change without the need for complicated regulation of a circuit, by mounting a heat sensitive resistance element at a path where charging and discharging currents flow to a piezo-electric element. CONSTITUTION:A heat sensitive resistance element Th of a negative property is mounted on a discharge path of a piezo-electric element Pi. Before a drive pulse signal Vs rises, transistors Q3 and Q1 are in an OFF state and a Q2 is in an ON state, and a voltage Vp applied to the opposite ends of the piezo-electric element Pi is brought to naught. When the pulse signal Vs rises, the transistors Q3 and Q1 are brought to ON in sequence, and simultaneously, the Q2 to OFF. Charge is accumulated in the piezo-electric element Pi and the voltage Vp applied to the opposite ends is equalized with a potential difference at a+ and a- side. Then, if the pulse signal Vs falls, the transistor Q3 is broughnt to OFF again, and the voltage Vp applied to the opposite ends of the piezo-electric element Pi changes. Since, however, a resistance element Th has a negative property, a width of a drive pulse Dp applied to the piezo-electric element Pi changes so as to perform a compensation in reaction to an ambient temperature.
