Benefits of technology

The present invention provides an ink-jet recording head, recording element substrate, and methods for manufacturing them that can ensure accurate bonding and positioning of the recording element substrates when they are bonded, even when a plurality of discharge ports are densely arranged. This is achieved by subjecting the second surface of each recording element substrate to etching, which ensures corrosion-resistant surface accuracy and reduces the likelihood of misaligned or damaged discharge ports during bonding. Overall, the invention improves the accuracy and reliability of ink-jet recording heads for high-quality printing.

Problems solved by technology

That is, it becomes more difficult to reduce the variations in the accuracy in cutting the recording element substrates using the known method of changing the distance between the substrates in accordance with variations since the intervals between the discharge ports are being reduced.

Embodiment Construction

[0024]Exemplary embodiments of the present invention will now be described with reference to the drawings.

[0025]FIG. 1 is a perspective view of an ink-jet recording head 1 according to an exemplary embodiment of the present invention. FIG. 2 is a cross-sectional view of the ink-jet recording head 1 taken along line II-II in FIG. 1. The ink-jet recording head 1 includes a plurality of recording element substrates 3 and a supporting member 5, and each of the recording element substrates 3 is disposed in a corresponding depression formed in the supporting member 5 (see FIG. 1). Furthermore, the recording element substrates 3 each include flow channels (see FIG. 2) through which ink flows and ink discharge ports 7. Ink is supplied from ink supply ports 9 formed in the supporting member 5, and is ejected from the ink discharge ports 7 to a print material through the flow channels of the recording element substrates 3. Moreover, heat-curable adhesives 11 are disposed between the recording...

Abstract

An ink-jet recording head includes a plurality of recording element substrates each having an ejection pressure generating element configured to generate pressure for ejecting ink from an ink discharge port. The plurality of recording element substrates each include a first surface on which the corresponding ejection pressure generating element is disposed and a second surface, serving as an end surface intersecting with the first surface, being at least partially formed by etching.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 12 / 636,001 filed Dec. 11, 2009, which claims the benefit of Japanese Patent Application No. 2008-320928 filed Dec. 17, 2008, all of which are hereby incorporated by reference herein in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to ink-jet recording heads, recording element substrates, methods for manufacturing ink-jet recording heads, and methods for manufacturing recording element substrates.[0004]2. Description of the Related Art[0005]Known full-line ink-jet recording heads are manufactured by aligning a plurality of recording element substrates composed of, for example, silicon or glass such that the recording element substrates are brought into contact with each other at end surfaces thereof (European Patent No. 0376514). However, since the recording element substrates are aligned by being brought into...
