=================================
The present invention relates to a set of ink cartridges which are filled with a plurality of kinds of inks, ink cartridges included in the set, a method for producing the set of ink cartridges, and an ink jet printer which forms an image with the inks contained in these ink cartridges.
BACKGROUND OF THE INVENTION
In general, an ink jet printer (ink jet recording apparatus) has a construction in which an ink cartridge filled with an ink are adopted to be installed to or mounted on a cartridge case. In such a printer, the ink contained in the ink cartridge mounted on the cartridge case is supplied to a recording head main body through an ink supply needle. (See, for example, Japanese Patent Application Laid-open No. 2000-218813.)
Japanese Patent Application Laid-open No. 2000-218813 discloses an ink jet printer having a cartridge case divided into a larger compartment and a smaller compartment. The larger compartment of the ink cartridge case are provided with three projections in the periphery of respective ink supply needles in an upstanding manner, and the height of the projections is greater than that of ink supply needles. A ink cartridge has three recesses formed in the lower surface thereof for engaging with the three projections of the ink cartridges cases. Accordingly, when the ink cartridges are mounted on the ink cartridge case, it is necessary that the positions of three projections and the positions of three recesses coincide with each other. Otherwise, the ink cartridge cannot be mounted on the ink cartridge case.
Accordingly, by changing the positions in which the projections and recesses are formed or the shape of the projections and recesses per each model of printer, it is possible to ensure that an ink cartridge is mountable only to a cartridge case included in the model of printer to which the ink cartridge corresponds. As a result, it is possible to prevent the ink cartridge from being mounted by mistake on a model of printer to which the ink cartridge does not correspond to.
