Abstract

PURPOSE: To stabilize the granule forming characteristics by adjusting the mechanical constant and drive frequency of an ink droplet forming mechanism so that the resonance of the mechanism may be prevented in the vicinity of the frequency of preset times of the drive frequency.
CONSTITUTION: If the masses the head 2A and fastening nut 5 of the nozzle of an ink injecting head constituting an ink droplet forming mechanism, the thickness and material of the electrodes 4 for piezoelectric oscillators 3A and 3B, and the whole length of the nozzle formed with a hole 2C are changed, the mechanical constant of the ink droplet forming mechanism is adjusted. By this adjustment and the adjustment of the oscillatory frequency of a driving electric signals source 6, the resonance of the mechanism is prevented at the frequency in the vicinity of natural number within the range from 2 to 10 of the driving frequency is prevented. As a result, in accordance with the oscillatory characteristics of invariable amplitude and oscillatory waveforms, the forming characteristics of the ink drop lets injected from the nozzle can be stabilized to accomplish the recording operation with the ink droplets
