Patent attributes
An inkjet head is composed of a plurality of plates stacked on each other. The plurality of plates includes a cavity plate formed with a plurality of ink pressure chambers and a plurality of manifold plates for forming a manifold chamber being in fluid communication with the ink pressure chambers to distribute ink thereamong. Each manifold plate is provided with an opening formed therethrough with a portion thereof being left in the opening. When the manifold chambers are stacked on each other, the openings of the manifold plates formed as above constitute a manifold channel taking the form of a closed loop. The portions of the manifold plates left in the openings are supported by a plurality of beams formed on the manifold plates. The beams are thinner than respective manifold plates, and are arranged so as not to overlap each other when viewed in a direction the manifold plates are stacked.
