    Abstract: An ink tank includes an ink containing portion for containing ink, a bottom surface provided with three projections for supporting the ink tank, an ink supply portion for leading ink out of the ink containing portion to the exterior a top surface opposing to said bottom surface, and a plurality of lateral surfaces adjacent to the bottom and top surfaces. The plurality of lateral surfaces include one set of opposing surfaces extended in a lengthwise direction of the ink tank. A grip portion is provided at one end of the ink tank in the lengthwise direction of insertion thereof. Two of the three projections are provided on the bottom surface in an opposed relation in areas near the opposing surfaces of the plurality of lateral surfaces, the ink supply portion being provided in an area of the top surface opposed to an area located on or within lines connecting the three projections.

    Abstract: Disclosed is an ink tank (1) for use in an ink jet recording apparatus comprising a recording head, an ink supply needle, a moving unit for moving the ink supply needle to a predetermined position, and a movement preventing unit which prevents movement of the ink supply needle caused by the moving unit, the recording apparatus being able to detachably mount the ink tank (1). The ink tank (1) comprises an ink containing portion (11) for containing ink, a projected portion (3) having an ink communicating portion (13) for communicating the ink containing portion (11) with the ink supply needle, a lock release portion (4) provided at a front end of the ink tank (1) in a direction of insertion thereof for releasing the movement preventing unit, a grip portion (7) provided at a rear end of the ink tank (1) in the direction of insertion thereof, and a vertical surface portion (6) extending upward from the grip portion (7) perpendicularly to a bottom surface of the ink tank (1) in an opposed relation to the projected portion (3). The vertical surface portion (6) has an upper end at a higher level from the bottom surface than an end face of the ink communicating portion (13) of the projected portion (3), and a lower end at a lower level from the bottom surface than a lower end of a lateral surface of the projected portion (3).
