  • Publication number: 20140022316
    Abstract: A cartridge includes N number of printing material supply ports, N being a natural number of 2 or more, a printing material containing section, and a negative pressure generating member. The N printing material supply ports are arranged along the Y axis in a surface. The printing material containing section is provided between a pair of side surfaces opposing each other in a direction along a Y axis, and contains a printing material. The negative pressure generating member is provided between the side surfaces, and generates negative pressure in the printing material containing section. A relationship between a length W1 along the Y axis from one of the side surfaces to the other and a length W2 along the Y axis of the negative pressure generating member between the one side surface and the other side surface satisfies W2<W1/N.

  • Patent number: 8534812
    Abstract: A cartridge loading/unloading device includes a cartridge holding mechanism 154 which holds a liquid cartridge 80 when a liquid cartridge 80 is inserted by a first predetermined stroke, and a power transmission converting mechanism 153 which ensures a push-in force required for loading of the ink cartridge 80 using the principle of the lever by the rotational motion of a lever arm 160, and which converts the rotational motion of the lever arm 160 into a second predetermined stroke S of movement required for loading of the ink cartridge 80 in a state in which it is held by the cartridge holding mechanism 154. The cartridge holding mechanism 154 includes an integral engaging member 155 which is engaged with the front side of one surface of the ink cartridge 80 in its loading direction across the center of the one surface.
