    摘要: The present invention relates to an ink cartridge detachably mounted on an ink jet printing apparatus for supplying ink to a printhead (5; 6) of the printing apparatus through an ink supply needle (6, 7), the ink cartridge comprising:
    a housing (4', 5') containing in therein having a first external wall and a second external wall intersecting said first external wall;
    an ink supply port (44, 54) formed on said first wall of said housing for receiving the ink supply needle and directing ink in said housing to the printhead;
    a circuit board (31) mounted on said second wall of said housing; and
    a semiconductor storage device (61) disposed on said circuit board for storing information about the ink carried by the ink cartridge; and
    a plurality of contact electrodes (60) arranged on said circuit board for electrically connecting said semiconductor storage device to the ink jet printing apparatus, said electrodes comprising at least one electrode (60-2) for contacting and grounding at least two contact forming members (29) of the printing apparatus when the ink cartridge is installed on the printing apparatus.

    摘要: Ink cartridge (43) for detachably mounting on a carriage (4) of an ink jet printing apparatus, the carriage having an ink supply needle (6) communicating with a print head (5), the ink cartridge comprising:
    a bottom wall and side walls in parallel with an insertion direction of the ink cartridge, the insertion direction being preferably vertical,
    an ink supply port (44) formed in the bottom wall to be engaged with the ink supply needle of the ink jet printing apparatus by moving the ink cartridge in the insertion direction,
    a circuit board (31) formed on a side wall adjacent to the bottom wall and being located in the vicinity of the ink supply port,
    a plurality of contacts (60) divided into plural rows, the contacts being disposed on the circuit board and a contact (60-1, 60-2) located in the center of one of the rows being disposed on the central line of the ink supply port,
    a semiconductor storage means (61) located on the circuit board and being connected to the contacts, and
    an overhang portion (46) on the side wall on which the circuit board is formed.
