LIQUID DISCHARGE HEAD, METHOD FOR MANUFACTURING SUCH HEAD, HEAD CARTRIDGE AND LIQUID DISCHARGING APPARATUS |
摘要 |
<p>The present invention provides a method for manufacturing a liquid discharge head comprising a top plate including a plurality of ink discharge ports for discharging ink droplet, a plurality of first liquid passages for supplying ink in correspondence to the plurality of ink discharge ports and a common liquid chamber for supplying the ink to the first liquid passages, a liquid discharge head substrate obtained by forming second liquid passages arranged adjacent to the first liquid passages and including bubble generating areas on a substrate on which a plurality of heat generating elements for causing the ink discharge port to discharge the ink droplets and including drivers for driving the heat generating elements, and a movable diaphragm for completely isolating the first liquid passages and the second liquid passages from each other and displaceable by a bubble generated on the heat generating element, wherein the method comprises a movable diaphragm forming step for providing the movable diaphragm in such a manner that a portion for fixing the movable diaphragm is covered. The present invention further provides such a liquid discharge head and a liquid discharging apparatus having such a liquid discharge head.</p> |
