Ink catridge for ink jet recording apparatus

摘要

An ink cartridge (8) employable for an ink jet type recording apparatus includes a fitting portion (4b) at the central part of a front plate (4a) of a case (4) so as to allow an ink outlet piece (2) secured to an ink bag (1) to be engaged with the fitting portion (4b). Once the ink outlet piece (2) is engaged with the fitting portion (4b), the ink bag (1) is located and received in the case (4). In addition, when two position determining shafts projecting from the innermost end of the cartridge holder are inserted through position determining holes (4g) and (4h) on the front plate (4a) of the case (4), an ink feeding needle projection from the innermost end of the cartridge holder is correctly located in alignment with the ink outlet piece (2) while the front plate (4) of the case serves as a reference. <IMAGE>
