Abstract
A liquid ejecting head includes: a nozzle plate provided with nozzle openings; an actuator unit including a flow channel formation substrate in which pressure generation chambers are provided and piezoelectric actuators that cause a change in the pressure of the liquid within respective pressure generation chambers; a communication substrate in which communication channels that communicate between the pressure generation chambers and corresponding nozzle openings are provided; a first case member that is a frame member affixed to the communication substrate so that the actuator unit is disposed within the first case member and that, along with the actuator unit, forms a manifold that holds the liquid to be supplied to the pressure generation chambers; and a second case member that is affixed to the first case member and in which is formed an introduction channel that sends the liquid from the exterior to the manifold.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
