Abstract
There is provided an ultrasonic printer in which convergent ultrasounds are radiated to emit an ink near a convergent point of the convergent ultrasounds in the form of an ink droplet and deposit the ink droplet on a recording medium such as a paper sheet, thereby performing a recording on the recording medium with multiple ink dots, with higher resolution. The ultrasonic printer has a plurality of ultrasonic transducers which transmit phase-controlled ultrasonic waves to form an convergent ultrasonic acoustic beam.
