ABSTRACT:
An ink-jet recording apparatus records an image onto a recording medium by flying an ink-droplet from an ink surface by a pressure of an ultrasonic beam. The apparatus including an ultrasonic generating element array having a plurality of ultrasonic elements arranged in an array for emitting ultrasonic beams, a driving device for applying a plurality of pulses having different phases from each other, and a converging device for converging the ultrasonic beams by interfering the ultrasonic beams with each other. The generating elements are simultaneously driven and sequentially shifted in an array direction, and the converging device converging the ultrasonic beams in a direction perpendicular to the array direction.
