Abstract

PURPOSE:To prevent the decrease of the quality of a printing by arranging a flight rate of an ink particle and a volume of its particle from each nozzle uniformly in respective of a wave shape of a driving voltage which is adjustable the value of the driving voltage of each piezo oscillator independently using the above printer. CONSTITUTION:A printing signal and a driving signal voltage of each piezo oscillator 7 are given to an input side of an analogue switch 17 of a driving signal source 13, and then the driving signal voltage is gated with the printing signal to actuate to an amplfier 15 as an input. By changing the setting value of the rate of the amplification with a variable resistance 14, the driving voltage applied to the piezoelectric oscillator 7 is allowed to change, thereby adjusting the voltage value so that the flight velocity of an ink particle in each nozzle may be constant. Then, by changing the driving signal voltage Vs simultaneously with a variable resistance 19, the flight velocity and the volume of the particles in all nozzles are allowed to change uniformly corresponding to the changes of the outer conditions in a state that the flight velocity in each nozzle is arranged.
