Abstract
A head unit is fixed to a main frame of a printhead. The head unit includes nozzles from which ink is ejected, pressure chambers each provided for a corresponding one of the nozzles, a common ink chamber that distributes the ink to the pressure chambers, an actuator that selectively applies ejection energy to the ink in the pressure chambers, an ink supply port connected to the common ink chamber, and a cylindrical member having a hollow and attached to the ink supply port. The main frame is provided with a through-hole toward which the cylindrical member is projecting. A coupling member is fixed to the main frame on a side opposite from the head unit such that the ink supply passage of the coupling member partially forms an ink path passing from an ink source, through the through-hole, to the hollow of the cylindrical member.
