Ink cartridge for use with recording apparatus and ink jet recording apparatus
First Claim
1. An ink cartridge that is inserted into to a cartridge holder of a recording apparatus and is attached to the cartridge holder during a recording operation to supply ink to the recording apparatus, comprising:
- an ink cartridge case having an ink chamber containing the ink;
an ink outlet port that is in fluid communication with the ink chamber and that is disposed at a first side of the ink cartridge case;
a first structure, which is at least partially formed at the first side of the ink cartridge case; and
a first positioning opening formed on the first side of the ink cartridge case, the first positioning opening receiving a first positioning pin formed on the cartridge holder when the ink cartridge is inserted into the cartridge holder;
wherein, when a first characteristic of the ink is compatible with a second compatible structure formed on the cartridge holder, the first structure is adapted to accept the second compatibility structure to enable the ink cartridge to be attached to the cartridge holder,wherein the second compatibility structure depends on the first characteristic of the ink.

Abstract
An ink cartridge including a cartridge case that contains an ink pack, on one surface of the cartridge case having an ink outlet port from the ink pack, a pressurized air inlet port and a connection terminal of a circuit board having a data storage means that stores ink information of the cartridge therein, a cartridge side compatibility detection mechanism and a positioning means used in case that the ink cartridge is attached to an ink jet recording apparatus. The cartridge is exactly positioned and fixed to a holder three-dimensionally by the positioning means, a mechanical positional adjustment and electrical connection can be exactly performed, so that operation reliability of the recording apparatus can be improved and even if ink leaks from the ink outlet port, the connection terminal can be prevented from being stained with the ink.
