Abstract
Three ink storage chambers stored into a main body case of an ink cartridge is isolated from four surfaces of this main case body by way of a partition and depressing partition portions projected from this portion. Also, these ink storage chambers are isolated from a bottom portion of the main body case by a stepped portion of a lower cylindrical portion, and is 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. A label reading apparatus is provided on the side of an ink-jet printer, and a printing operation by any ink cartridge other than the genuine-labeled in 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.
