  • Patent number: 6536870
    Abstract: An ink jet recording cartridge mounted on a movable carriage comprises an ink jet recording head for recording by discharging ink from the discharge ports to a recording medium, and a housing for holding the ink jet recording head. For the housing of this cartridge, extrusions are arranged to abut upon the grooved portions arranged for the carriage, and the extrusions are made capable of adjusting the relative positions of the ink jet recording cartridge and the carriage. With the ink jet recording cartridge thus structured, it becomes possible to position the discharge ports of the recording head easily and exactly corresponding to the predetermined position in the carriage. Even if the precision varies when the recording head is installed on the housing of the cartridge, the extrusions are arranged to shift in accordance with such variation to serve the purpose.
