发明名称 Ink-jet recording apparatus and ink tank cartridge therefor
摘要 An ink tank cartridge is provided removably mountable onto an ink supply needle of the ink-jet type recording apparatus body. The cartridge has a housing provided with an ink supply port extending through and projecting from a wall of the housing and into the chamber of the housing. A porous member having ink impregnated thereon is positioned inside the chamber of the housing abutting against the ink supply port. A filter is mounted on the inner end opening of the ink supply port. The ink tank cartridge is further provided with a packing member for resiliently abutting against the outer periphery of the ink supply needle and is positioned adjacent one end of the ink supply port. The outer opening of the ink supply port is sealed with a sealing member through which the ink supply needle penetrates. A further porous member may be positioned in the ink supply port between the packing member and the filter to prevent a false ink end indication caused by air reaching an electrode of an ink end sensor positioned between the filter and the further porous member when the ink tank cartridge is removed from the recording apparatus.
