Abstract
An ink cartridge in which on one surface of a cartridge case, there are provided a positioning means used in case that the ink cartridge is attached to a recording apparatus, an ink outlet port from an ink pack, an inlet port of the pressurized air and a connection terminal of a circuit board having a data storage means that stores ink information of the cartridge therein, and an ink jet recording apparatus provided with its ink cartridge are provided.
According to the ink cartridge of this mode, since the cartridge is exactly positioned and fixed to a holder three-dimentionally by the positioning means, mechanical positional adjustment and electrical connection can be exactly performed, so that operation reliability of the recording apparatus can be improved. Further, in the recording apparatus of this mode, in a state where the cartridge has been mounted on the recording apparatus by the positioning means, the connection terminal of the board is located at the upper portion of the ink outlet port. Hereby, even if ink leaks from the ink outlet port, the connection terminal can be prevented from being stained with the ink.
