Abstract
A recessed portion is formed in an ink cartridge 1 to define a three-dimensional space. Each of axes in the three-dimensional space containing one side surface of the ink cartridge in which an ink supply port 14 is formed is divided into a plurality of sections to obtain a plurality of coordinate points. Identification protruded portions 31-1 to 31-3 which serve as. identification pieces are disposed selectively at the coordinate points in accordance with identification items.
Claims30
An ink-jet recording device for supplying ink to a recording head from at least one ink cartridge having an ink supply port, the recording device comprising:
- at least one identification member protruded in a direction parallel to an insertion direction of the ink cartridge into the recording device, wherein:
- the identification member has a shape corresponding to the ink cartridge, the identification member reaching one of a plurality of threedimensionally arranged coordinate points, which is selected in accordance with the ink cartridge;
- and
- the coordinate points are defined by dividing each of the three-dimensional space axes into a plurality of sections.
An ink cartridge comprising:
- a container for storing ink;
- an ink supply port disposed on one surface of the container;. at least one identification fitting portion shaped to identify a property of the ink cartridge, wherein:
- the identification fitting portion is located proximate one of a plurality of three-dimensionally arranged coordinate at points, which is selected in accordance with an identification item;
- and
- the coordinate points are defined by dividing each of the three-dimensional space axes containing the surface into a plurality of sections.
An ink-jet recording device, adapted for mounting of an ink cartridge in an ink cartridge mounting region, for supplying ink to a recording head from the ink cartridge having an ink supply port, the recording device comprising:
- at least one identification member disposed on the ink cartridge mounting region, and protruded in a first direction parallel to a cartridge insertion direction and in a second direction parallel to a cartridge depth direction,
- wherein a position of an end portion of the identification member in the first direction, a position of an end portion of the identification member in the second direction and a location where the identification member is formed in a third direction perpendicular to the cartridge insertion direction are defined in accordance with identification items.
An ink cartridge comprising:
- an ink container:
- an ink supply port disposed on the container;
- and
- at least one identification fitting portion, wherein:
- a location of the identification fitting portion is determined with respect to a first direction parallel to a cartridge insertion direction, a second direction perpendicular to the first direction and a third direction perpendicular to both of the first and second directions, in accordance with identification items.
