Abstract: PURPOSE:To obtain sufficient insulation through a simple insulating treatment, by driving a recording electrode at a predetermined period, and generating a potential difference sufficient for causing an ink at a tip part of the recording electrode to fly, between the recording electrode and an opposing electrode according to a printing signal when the recording electrode approaches the opposing electrode. CONSTITUTION:When a motor 47 is rotated to rotate a rotary body 45, each angular part 45b deforms a leaf spring 44. As a result, a recording electrode 43 is repeatedly moved toward and away from an opposing electrode 34 at a predetermined period. When a printing signal is selectively supplies to a switching circuit 50 when the recording electrode 43 approaches the opposing electrode 34, an ink 39 is caused to fly from a tip part of the recording electrode 43, resulting in printing. To vary the pitch of dots, the rotating speed of the rotary body 45 or the velocity of a carrier is varied. In addition, the quantity of the ink caused to fly can be changed by shifting the timing of supplying the printing signal. Since there is not need for applying a high voltage between the recording electrode 43 and the opposing electrode 34 so as to cause the ink 39 at the tip part of the recording electrode 43 to fly, an insulating treatment is facilitated.
