Abstract
Official abstract text for this publication.
A recording apparatus including an ink tank and a recording head having a flow path forming portion that has an ejection orifice plate having plural ink ejection orifices and a liquid chamber provided for each orifice to supply ink to the orifices, and an energy generating element for ejecting ink in the chamber. A surface layer of the flow path forming portion opposes to the outside of the plate. An opening is provided opposing to the orifices in the surface layer. An ink reservoir is provided between the plate and the opening. A circulation flow path communicating with the ink reservoir is provided. The area of the opening is larger than that of the orifice. Both ends of the circulation flow path are respectively connected to inlet and outlet portions connected to the circulation flow path. The inlet and outlet portions and liquid chamber are connected to the ink tank.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid ejection head comprising: a substrate having an element that generates energy utilized for ejecting liquid and having a lead-in port that is a through-hole and a lead-out port that is a through-hole; and a member having an ejection orifice that ejects the liquid, wherein the liquid that is supplied from the lead-in port to the lead-out port through a flow path portion where the element is arranged flows through a flow path from an opening of the…
