Abstract

An inkjet printer head including: (a) a front head unit having (a-i) an outside surface which is to be opposed to a print media, (a-ii) an inside surface opposite to the outside surface, (a-iii) a plurality of nozzles opening in the outside surface and arranged in row, and (a-iv) an ink inlet opening in the inside surface; (b) an ink-channel defining unit supplying an ink into the front head unit through the ink inlet; (c) a head holder holding the front head unit; and (d) a reinforcement member fixed to the inside surface of the front head unit. The front head unit and the head holder are fixed to each other, with the reinforcement member being interposed therebetween. The ink-channel defining unit is fixed to one of opposite side surfaces of the reinforcement member that is remote from the front head unit. Also disclosed is an inkjet printer including the above-described inkjet printer head, a carriage, a heat dissipater and a bubble discharger, wherein the heat dissipater, bubble discharger and front head unit are mounted on the carriage, and are arranged in a direction of movement of the carriage.

Description

[0001] The present invention is based on Japanese Patent Application No.2003-405972 and No.2003-405973 filed on December 4, 2003 and Japanese Patent Application No.2003-424453 filed on December 22, 2003, the contents of which are incorporated herein Reference. technical field [0002] The present invention relates to an inkjet printhead provided with a head unit and an ink passage defining unit connected to each other, and to an inkjet printer equipped with such an inkjet printhead. Background technique [0003] There is known an inkjet printer that performs a printing operation by ejecting ink droplets to a printing medium (such as paper) through nozzles in accordance with an input signal. Conventionally, such printers include a head unit including a nozzle-formed member, and the nozzle-formed member provides an outer surface of the head unit, which is opposed to a printing medium. For example, U.S. Patent No. 5,748,214 (corresponding to JP-A-H08-276586) discloses an inkje...
