PROBLEM TO BE SOLVED: To ensure printability with high image quality and high gradation by averting the waveform distortion of a drive pulse, inhibiting/preventing the weight fluctuations of a liquid from occurring or averting a lag in the jet timing of the liquid. SOLUTION: Only one actuator 22 is made available for connection with a drive circuit by installing the same number of transistor pairs for amplifying electric power for a drive waveform signal WCOM as the number of actuators, and interposing a smoothing filter 26 between the transistor pair and the actuator 22. Thus, the waveform distortion of the drive pulse can be averted. In addition, the generation of the drive waveform signal WCOM complying with the actuator 22 and a nozzle, can be achieved by providing the same number of modulation circuits 24 for the drive waveform signal WCOM and gate drive circuits 34 for driving the transistor pair as the number of the transistor pairs. Consequently, the weight fluctuations of the liquid between the nozzles are inhibited and prevented from occurring. Besides, a lag in the jet timing of the liquid can be averted by simultaneously generating the drive waveform signal WCOM to the actuators 22 for jetting the liquid. COPYRIGHT: (C)2008,JPO&INPIT |
