Title:

LIQUID-JET HEAD AND LIQUID-JET DEVICE USING THE HEAD

Document Type and Number:

WIPO Patent Application WO/2004/082943

Kind Code:

A1

Abstract:

A liquid jet head in which the direction of jet of ink is controlled by means of heating resistors. A liquid jet head has, on a semiconductor substrate (101), heating resistors (102a, 102b) provided near to each other in an ink chamber (105) and adapted to produce a bubble in the ink supplied into the ink chamber (105) so as to jet ink from a nozzle (104a), a switch element (121a) for supplying powers to the heating resistors, and switch elements (121b, 121c) for supplying different powers to the respective heating resistors or supplying a power to them at different times so as to control the direction of jet of ink. On the semiconductor substrate (101), a power supply wiring pattern (224) for supplying powers to the heating resistors and a control wiring pattern (236) for controlling the switch elements (121a, 121b, 121c) are provided in the respective conductive layers.
