Patent ID: 8657400

Claim:
A liquid discharging apparatus comprising: a pressure chamber communicating with a liquid supply portion and one or more nozzles; an element that performs an operation for providing change of pressure to liquid within the pressure chamber; and a pulse generating section that generates a pulse of which a voltage is changed to operate the element, wherein the pulse generating section generates a first discharge pulse that causes the element to perform an operation for discharging liquid droplets from the nozzles, a non-discharge pulse, generated later than the first discharge pulse, that produces pressure vibration with an amplitude less than an amplitude required for the liquid droplets to be discharged from the nozzles, in the liquid within the pressure chamber, which has a phase different from pressure vibration produced in the liquid within the pressure chamber by applying the first discharge pulse to the element, and a second discharge pulse, generated later than the non-discharge pulse, that causes the element to perform the operation for discharging the liquid droplets from the nozzles, while using constructive interference between the pressure vibrations caused by the second discharge pulse and the non-discharge pulse, and wherein an amount of the ink drops discharged by the second discharge pulse is larger than an amount of the ink drops discharged by the first discharge pulse.
