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

摘要

The present invention relates to a liquid discharge head that controls ink discharge direction using a plurality of heating elements.

<Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">The liquid discharge head comprises, on a single semiconductor substrate (101), a plurality of heating elements (102a) (102b) that are adjacently disposed to each other in an ink liquid chamber (105) and generates bubbles in the ink supplied to the ink liquid chamber to discharge the ink from a nozzle (104a), a switching element (121a) that supplies power to the heating elements, and switching elements (121b) (121c) that control the ink discharge direction while supplying different levels of power to the heating elements or changing the timing of giving power thereto. On the semiconductor substrate, an energy supply wiring pattern (224) for supplying power to the heating elements and a control wiring pattern (236) for controlling the switching element (121a) and switching elements (121b) (121c) are provided in different conductive layers.
