Patent ID: 7686426

Claim:
A liquid transporting apparatus which transports a liquid having an electroconductivity, comprising: a liquid transporting head which includes: a plurality of common channels, a plurality of individual channel groups each of which corresponds to the common channels, each of which has a plurality of individual channels branched from one of the common channels, a plurality of common electrodes each of which is arranged on a channel forming surface of one of the common channels, and is in direct contact with the liquid in one of the common channels, a plurality of individual electrodes each of which is arranged on a channel forming surface of one of the individual channels, and an insulating layer which is arranged to cover each of the individual electrodes, and in which a wetting angle of the liquid on a surface of the insulating layer is decreased to be not more than a critical wetting angle at which the liquid is remainable on the surface thereof, when an electric potential difference between the liquid in the individual channel and the individual electrode is not less than a predetermined critical electric potential difference; and a control mechanism which controls a liquid transporting operation of the liquid transporting head, wherein an individual electrode among the individual electrodes provided to one of the individual channels of an individual channel group among the individual channel groups corresponds to another individual electrode provided to one of the individual channels of another individual channel group, and the corresponding individual electrodes are mutually conducted.
