Abstract:
A liquid ejecting head includes an ejecting section including a pressure chamber filled with liquid, a communicating flow channel communicating with a nozzle which ejects the liquid filling the pressure chamber, and a piezoelectric element driven with a drive signal, a circuit substrate provided above the ejecting section, a switch circuit which is provided on the circuit substrate, and a reserve chamber which reserves the liquid to be supplied to the pressure chamber. The piezoelectric element is provided in a sealed space defined by a plurality of members including the circuit substrate, the pressure chamber includes an inlet port allowing the liquid within the reserve chamber to flow into the pressure chamber, an outlet port allowing the liquid within the pressure chamber to flow to the reserve chamber, and a supply port allowing the liquid within the pressure chamber to be supplied to the communicating flow channel.

Claim (Index 14):
A liquid ejecting head comprising:\n a first pressure chamber filled with liquid; a second pressure chamber filled with the liquid; a reserve chamber which reserves the liquid to be supplied to the first pressure chamber and the second pressure chamber; a first connecting flow channel which has one end communicating with the first pressure chamber and the other end communicating with the reserve chamber; a second connecting flow channel which has one end communicating with the second pressure chamber and the other end communicating with the reserve chamber; a link flow channel which has one end communicating with the first pressure chamber and the other end communicating with the second pressure chamber; a nozzle which ejects the liquid filling the first pressure chamber; a vibration plate constituting the wall surface of the first pressure chamber; a piezoelectric element driven with a drive signal; a circuit substrate provided on the vibration plate; and a switch circuit which is provided on the circuit substrate and switches between supply and shut-off of the drive signal to the piezoelectric element, wherein the piezoelectric element is provided in a sealed space defined by a plurality of members including the circuit substrate.
