Patent ID: 7712885

Claim:
A liquid-droplet jetting apparatus which has a body and which jets liquid droplets of a liquid, comprising: a plurality of first pressure chambers; a first pressure-chamber row in which the first pressure chambers are arranged in a first direction; a plurality of second pressure chambers; a second pressure-chamber row in which the second pressure chambers are arranged in the first direction; a first common liquid chamber which extends in the first direction and which communicates with each of the first pressure chambers; a second common liquid chamber which extends in the first direction and which communicates with each of the second pressure chambers; and a damper which extends in the first direction and which is located between the first common liquid chamber and the second common liquid chamber in a thickness direction of the body; wherein the first common liquid chamber has a width in a second direction, which is orthogonal to the first direction, so as to overlap with the second common liquid chamber in the thickness direction; wherein the damper has a width in the second direction so as to overlap with each of the first common liquid chamber and the second common liquid chamber in the thickness direction; wherein each of the first common liquid chamber, the second common liquid chamber, and the damper has the width in the second direction so as to overlap in the thickness direction with the first pressure-chamber row and the second pressure-chamber row; and wherein the first pressure-chamber row and the second pressure-chamber row are arranged in the second direction with respect to each other.
