クジエツトプリンタのインク噴射駆動回路。 An ink ejection drive circuit for an inkjet printer that outputs the drive voltage in an inkjet printer that ejects ink by the electrostrictive action of the piezoelectric element generated by applying a drive voltage between both electrodes of the piezoelectric element. When the print command signal is not input, a voltage of zero volts is output as the drive voltage, and when the print command signal is input, the drive voltage is a first voltage having a predetermined value and a predetermined time width. An inkjet printer characterized in that after outputting a voltage, a second voltage having a smaller value than the first voltage is output, and when the input of the print command signal disappears, a voltage of zero volts is output again as the drive voltage. ink jet drive circuit.
