PURPOSE:To decrease the white portions of a picture without zigzag arranging nozzles, by mounting vibrating means for printing paper, and by conforming the period of vibration to the spacing of dots in the travelling direction of printing paper or by forming the period in plural times. CONSTITUTION:An electrostriction vibrator 20 is fastened to one end of a head while the other end of the vibrator 20 is fast sticked to a fixed wall. Since a multinozzle-head is contacted by means of a bearing 23 pushed by means of a spring 24, the head largely moves in the vertical direction by means of a vibrator 3 using a big electrostriction vibrator while it shifts in the horizontal direction (the arrow head B direction) by means of the small electrostriction vibrator 20. when the AC frequency of a signal feed circuit 21 applied to the electric distortion trembler 20 is made to be half the number of vibration of the vibrator 3, particles injected from one nozzle are each let reach to different two locations, and paper is printed. |
