INK CARTRIDGE AND RECORDING APPARATUS
First Claim
1. An ink cartridge adapted to be mounted on a recording apparatus including a cartridge storage portion which has an ink supply needle for supplying ink to a recording head and a rib for regulating a position in a widthwise direction of the ink cartridge, comprising:
- a top wall, a bottom wall, a first side wall intersecting the bottom wall, and a second side wall intersecting the bottom wall and facing the first side wall;
an ink supply port engageable with the ink supply needle and disposed on the bottom wall at an offset position closer to the first side wall than the second side wall;
a projecting portion disposed on the second side wall and located closer to the bottom wall than to the top wall, the projecting portion having two side portions which are adapted to be regulated by the rib in the widthwise direction and a top surface which is parallel to a loading direction that the ink cartridge is inserted into the cartridge storage portion, the projecting portion formed at a position offset to one side of the ink cartridge in the widthwise direction;
a circuit board fixed on the top surface;
a plurality of electrodes formed on the circuit board; and
a memory unit connected to at least some of the plurality of electrodes and mounted on the circuit board.
