ABSTRACT:
When an ink stream spouting from a nozzle is subjected to mechanical vibrations of a certain magnitude, the fore end of the ink stream alternately separates into larger and smaller ink droplets in synchronism with the vibrations. This invention varies the flight velocity of the small-diameter ink droplets relative to that of the large-diameter ink droplets according to information to-be-recorded and thus controls the union between the large- and small-diameter ink droplets. By exploiting the difference between the amounts of deflection of the large-diameter ink droplet and a united ink droplet created by the union of the large- and small-diameter ink droplets, the information is recorded on a recording medium.
