<p>An ink cartridge adapted to be inserted into a recording apparatus, the ink cartridge comprising:
a top wall, a bottom wall (3;103), a front wall (7;107) intersecting the bottom wall, a back wall (8;108) intersecting the bottom wall and facing the front wall, a first side and a second side facing the first side, wherein a distance between the first and second side defines the thickness of the ink cartridge;
an ink supply port (4;104) disposed on the bottom wall at an offset position closer to the front wall than to the back wall;
a first projecting portion (12;112) disposed on the back wall and located closer to the bottom wall than to the top wall;
a circuit board (15;115) fixed on the first projecting portion parallel to the back wall;
a plurality of electrodes (14;114) formed on the circuit board;
a memory unit (18) connected to at least some of the plurality of electrodes and mounted on the circuit board; and the first projecting portion having flat side surfaces (12b,c;112a,b) projecting from the back wall parallel to the first and second side, wherein the distance between the flat side surfaces in the thickness direction is smaller than the thickness of the ink cartridge, so that the flat side surfaces are located close to the respective end of the circuit board in the thickness direction of the ink cartridge, and one of the flat side surfaces is substantially flush with the first side.</p> |
