Laminated liquid-jetting head capable of recording in a plurality of colors, a method of producing the head and an apparatus having the head

A liquid-jetting recording head capable of recording in a plurality of colors, the head comprising a base member having a plurality of heaters thereon and a plurality of perforations therethrough, at least one plate member having at least one perforation therethrough surrounded on all sides by said plate member, and an orifice plate having holes therethrough, wherein:

• said base member, said plate member and said orifice plate are laminated together to provide a laminated liquid-jetting recording head having a plurality of substantially identically shaped, separate liquid supply paths, each being in communication with an associated perforation in said base member for supplying different color recording liquids to said liquid supply paths;
• each said liquid supply path includes a main liquid path and a plurality of said branched liquid paths branched off from said main liquid path, said liquid supply paths, said main liquid paths and said branched liquid paths being formed by said perforation through said plate member;
• and
• liquid can be ejected from the liquid-jetting head through said holes in said orifice plate by the action of heat energy applied to the liquid in the branched paths by said heater.

A multi-color image recording apparatus comprising a liquid-jetting recording head, means for supplying different color recording liquid to said liquid-jetting head and means for controlling deposition of recording liquid by said liquid-jetting recording head on a recording medium, said recording head including a base member having a plurality of heaters thereon and a plurality of perforations therethrough, at least one plate member having at least one perforation therethrough surrounded on all sides by said plate member, and an orifice plate having holes therethrough, wherein:

• said base member, said plate member and said orifice plate are laminated together to provide a laminated liquid-jetting recording head having a plurality of substantially identically shaped, separate liquid supply paths, each being in communication with an associated perforation in said base member for supplying different color recording liquids to said liquid supply paths;
• each said liquid supply path includes a main liquid path and a plurality of said branched liquid paths branched off from said main liquid path, said liquid supply paths, said main liquid paths and said branched liquid paths being formed by said perforation through said plate member;
• and
• liquid can be ejected from the liquid-jetting head through said holes in said orifice plate by the action of heat energy applied to the liquid in the branched paths by said heater.
