Ink jet print head for ink jet printer

摘要

Several print chambers (2a,2b) are offset from each other in an outer region and an inner region. The print chambers in the outer region have a circumferential length which is the same as or is larger than that of the point chambers in the inner region and a radial length which is the same as or is less than that of the point chambers in the inner region. Alternatively the print chambers in the outer region and piezoelectric elements have a circumferential length which is the same as or is greater than the radial length. Alternatively the print chambers in the inner region and piezoelectric elements have a radial length which is the same as or is greater than the circumferential length.
