Abstract:
A liquid discharging apparatus includes: a channel member formed with an individual channel, the individual channel including a nozzle and a pressure chamber; a piezoelectric element arranged in the channel member and facing the pressure chamber, the piezoelectric element being configured to apply pressure to liquid in the individual channel; and a driver configured to apply a driving signal to the piezoelectric element, the driving signal being constructed of a plurality of pulse waveforms, wherein the piezoelectric element is driven in a pull-strike system by one piece of the pulse waveforms such that the pressure chamber is depressurized and then pressurized.
