<P>PROBLEM TO BE SOLVED: To provide a liquid jet device solving problems related to an FFC (Flexible Flat Cable) or an electric cable for outputting a drive signal to a nozzle actuator, and especially preventing waveform distortion of the drive signal. <P>SOLUTION: This liquid jet device is provided with: a plurality of nozzles for jetting a liquid in a liquid jet head 2; and the nozzle actuator 22 in each nozzle. The liquid jet head 2 is provided with: a smoothing filter 29; and a digital power amplifier 28 power-amplifying a control signal from a control circuit 23 and outputting it to the nozzle actuator 22 as the drive signal COM, both correspondingly to each nozzle actuator 22, when jetting the liquid toward a print medium 1 from the corresponding nozzle by driving each nozzle actuator 22 of the liquid jet head 2 by the drive signal COM. <P>COPYRIGHT: (C)2009,JPO&INPIT |
