Patent ID: 7874652

Claim:
A liquid transporting apparatus which transports a liquid from a liquid supply port to a plurality of liquid jetting ports, comprising: a plurality of pressure chambers which are formed, corresponding to the plurality of liquid jetting ports respectively, in channels each from the liquid supply port up to one of the liquid jetting ports; a channel unit in which the pressure chambers open; and a piezoelectric actuator which changes a volume of each of the pressure chambers individually; wherein the piezoelectric actuator includes a vibration plate, a piezoelectric body which provided on one surface of the vibration plate, a first electrode provided on a surface, of the piezoelectric body, on a side of the vibration plate, and a second electrode provided, on the piezoelectric body, on the other surface not facing the vibration plate, and which is joined to the channel unit such that the other surface of the vibration plate closes openings of the pressure chambers, and the one surface of the vibration plate has an uncovered area which is not covered by the piezoelectric body, and a heater is provided in the uncovered area, the heater generating heat by being applied with an electric current, and an electrode for applying the electric current to the heater is provided independently of the first electrode and the second electrode of the piezoelectric actuator.
