Patent ID: 7681987

Claim:
An inkjet recording head comprising: a first plate formed with a plurality of nozzles arranged in a row for ejecting ink droplets, and a plurality of connecting channels each having a first end in fluid communication with a corresponding one of the plurality of nozzles, the plurality of the connecting channels extending from the first ends alternately in opposite directions that are angularly shifted from a direction orthogonal to the row of the nozzles, each of the plurality of connecting channels extending in a channel direction orthogonal to a nozzle direction that each of the plurality of nozzles extends; and a second plate formed with a plurality of pressure chambers in fluid communication with second ends opposite the first ends of the connecting channels in a one-on-one correspondence to the nozzles, the pressure chambers being formed in two rows parallel to the row of nozzles, one row of the pressure chambers being on one side of the row of nozzles and the other row of pressure chambers being on the other side of nozzles, at least a region of each of the pressure chambers in one row being aligned with one of the pressure chambers in the other row in the direction orthogonal to the row of nozzles; a third plate having a vibration plate that seals the pressure chambers; and a pressure generating member having a plurality of drive elements that contact portions of the vibration plate opposing the regions of the pressure chambers.
