<p>Three ink storage chambers (68) stored into a main body case of an ink cartridge (44) are isolated from four surfaces of this main case body by way of a partition (66) and depressing partition portions projected from this portion (76). Also, these ink storage chambers are isolated from a bottom portion of the main body case by a stepped portion (79) of a lower cylindrical portion (77), and are arranged by forming space between a lid and the own ink chambers. Only refilling hole portions of an upper cylindrical portion are communicated with an external portion via holes of the lid. A label on which a trademark 'ABC' is printed is attached onto the upper portions of the three refilling hole portions (72). A label reading apparatus (31) is provided on the side of an ink-jet printer, and a printing operation by any ink cartridge other than the genuine-labeled ink cartridge is not carried out. As a genuine ink refilling member, at least ink bottles and a label are employed as a set of such a genuine ink refilling member. The ink cannot be refilled via a hole formed in any portion of an ink cartridge, except for the refilling hole portion.</p> |
