Abstract:
An ink-jet recording apparatus, for recording an image onto a recording medium by flying an ink-droplet from an ink surface by a pressure of an ultrasonic beam, comprising:first converging means having an ultrasonic generating element array which has ultrasonic generating elements arranged in a linear array for emitting ultrasonic beams by applying a plurality of pulses having different phases from each other to converge said ultrasonic beams, in a first direction along a linear array direction of said ultrasonic generating elements, by interfering said ultrasonic beams with each other; emitted from said ultrasonic generating elements of a part of said ultrasonic generating element array, which are simultaneously driven, by sequentially shifting said ultrasonic generating elements simultaneously driven in the array direction; andsecond converging means for converging each of said ultrasonic beams to a predetermined point in a direction parallel to said first direction.
