<P>PROBLEM TO BE SOLVED: To reduce a variation in droplet speed due to a drive frequency while preventing an increase in a waveform length by adding a pulse other than a fine drive pulse for preventing thickening, in a droplet discharge device. <P>SOLUTION: In a droplet discharge device, a drive control part 100 selects a discharge drive waveform for droplet discharge or a fine drive waveform for imparting micro vibration for each time period element to perform discharge control of a droplet, wherein the drive control part 100 adjusts a time interval between the rising of the fine drive waveform and the rising of the discharge drive waveform in one time period element immediately thereafter so that a droplet discharge speed at a low frequency is approximately equal to a droplet discharge speed at a high frequency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
