Abstract:
An inkjet printer includes a head, a drive voltage generating circuit, a carriage, and a magnet array. The head includes a nozzle and an ejection element. The ejection element is configured to be driven, when applied with a drive voltage, to eject ink from the nozzle. The drive voltage generating circuit is configured to generate the drive voltage to be applied to the ejection element. The carriage is configured to move in a moving direction to move the head and the drive voltage generating circuit in the moving direction. The magnet array includes a plurality of magnets arrayed in the moving direction. The drive voltage generating circuit includes a coil configured to produce an electromotive force by interlining with magnetic flux of the magnet array in accordance with movement of the carriage. The drive voltage generating circuit generates the drive voltage using the electromotive force produced by the coil.
