PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus capable of preventing the data destruction in a semiconductor storage means regardless of an improper attachment to or removal from of an ink cartridge, and an ink cartridge for the inkjet recording apparatus. SOLUTION: In the inkjet recording apparatus, an ink supply needle 6 is located near one side in a direction perpendicular to the reciprocated directions of a carriage 3. A circuit board 31 is mounted on a wall of an ink cartridge 40 in the vicinity of the side on which an ink supply port 44 is formed and a plurality of contacts for connecting to an external control means are formed on the exposed surface of the circuit board 31. Therefore, even if a clearance is present between the carriage 3 and the ink cartridge 40, the movement path is restricted by the ink supply needle 6 and the ink supply port 44, and the contacts are made to the external control means in a prescribed order. As a result, the data loss due to the application of signals in a wrong, careless order in the semiconductor storage means is prevented. COPYRIGHT: (C)2009,JPO&INPIT |
