US Patent 7399042 Head driving device

A head driving device of a liquid ejecting apparatus includes a pressure generating element, a bias voltage applying unit which applies a bias voltage to the pressure generating element, a driving voltage generating unit which generates and outputs a driving voltage to the pressure generating element for ejecting a liquid droplet from a nozzle of a liquid ejecting head, and a cutoff unit which cuts off the bias voltage applied to the pressure generating element based on an outputting of a drive stopping signal.
