ABSTRACT:
An apparatus for liquid-jet recording comprises an electro-thermal transducer and discharge openings for jetting a liquid by thermal action of the electrothermal transducer. The electro-thermal transducer is connected directly to a lower potential side of a power source and is connected to a higher potential side of the power source through a switch element. Thermal action of the thermal transducer occurs upon the application of a positive voltage of a high potential from the power source through the switch element.
