Ink cartridge
First Claim
1. A structure holding a memory device for installation in an ink jet printer that has a holding portion with an ink supply needle, a projecting member and a plurality of printer electrodes, comprising:
- the memory device, the memory device including a semiconductor memory and a plurality of electrodes which, when the structure is installed in the ink jet printer, are respectively contacted by corresponding printer electrodes, the plurality of electrodes situated in an electrode region; and
a body having;
a first wall portion that comprises a first plane, and a second wall portion that comprises a second plane, the second wall portion being substantially orthogonal to the first wall portion and the first plane being substantially orthogonal to the second plane, the memory device being mounted to the first wall portion so that at least a portion of the electrode region is situated along the first plane and the plurality of electrodes face outward, the second wall portion having an aperture situated along the second plane and dimensioned and disposed to receive the projecting member when the structure is installed in the ink jet printer.
