PROBLEM TO BE SOLVED: To provide a circuit of a liquid discharge device capable of reducing necessary voltage resistance performance or necessary current resistance performance.SOLUTION: A printing device 100A includes a plurality of piezoelectric elements 40, a plurality of drivers 30, and an auxiliary power supply part 50. Each of the plurality of piezoelectric elements 40 discharges droplets from nozzles by charge and discharge. The plurality of drivers 30 are installed in one-to-one correspondence with the plurality of piezoelectric elements 40. Each driver 30 selectively supplies a plurality of voltage for the piezoelectric elements 40. The auxiliary power supply part 50 generates the plurality of voltage and commonly supplies the plurality of voltage for the plurality of drivers 30.SELECTED DRAWING: Figure 1 |
