INKJET HEAD AND INKJET APPARATUS HAVING THE SAME

摘要

An inkjet head includes a substrate having plural ink inlet holes arranged along a first direction and plural ink outlet holes arranged generally along the first direction such that adjacent ink outlet holes are offset along the first direction, a plurality of partitioning walls made of piezoelectric material that define pressure chambers therebetween, each of the partitioning walls disposed on the substrate and generally extending in a second direction that crosses the first direction between the ink inlet holes and the ink outlet holes, and a nozzle plate disposed on the partitioning walls and having a plurality of nozzles, each of the nozzles being arranged on one of the pressure chambers.
