摘要

PURPOSE: An ink-jet recording device and an ink cartridge are provided to increase the number of shape for the decision of the suitability by using a narrow space. CONSTITUTION: A recessed portion is formed in an ink cartridge to define a three-dimensional space. Each of axes in the three-dimensional space containing one side surface of the ink cartridge in which an ink supply port is formed is divided into a plurality of sections to obtain a plurality of coordinate points. Identification protruded portions(31-1 - 31-3) which serve as identification pieces are disposed selectively at the coordinate points in accordance with identification items. Thereby, various kinds of ink cartridges are installed to be suitable for a recording device without any mistakes. Moreover, the number of the shapes for the decision of the suitability by using a narrow space is increased.
