摘要： A liquid container which can precisely detects existence/absence of residual liquid at a low cost, a cartridge including the liquid container, and a printing apparatus using the cartridge. The lengthwise direction of a triangular prism provided on the bottom of the ink tank is along a direction of print medium conveyance in the printing apparatus, such that when an ink-jet head cartridge holding the ink tank is attached to the printing apparatus for performing printing, light emitted from an optical unit of the printing apparatus is precisely captured by the prism. Further, if two ink-jet head cartridges are mounted on the printing apparatus, the first and second ink-jet head cartridges are set in positions shifted from each other by a length shorter than the length in the lengthwise direction of the prism, such that the light emitted from the optical unit reaches the prisms provided in the ink tanks of the first and second ink-jet head cartridges.

摘要： An ink tank having a negative pressure generating member for retaining ink, a case for accommodating the negative pressure generating member, the case having an atmosphere communicating portion held in communication with the atmosphere and an ink supply portion through which the ink is led out to the exterior, and an ink holding member disposed near the ink supply portion and developing a higher capillary action than the negative pressure generating member, wherein a recess is formed in an inner surface of a side wall of the case adjacent to a wall provided with the ink supply portion, the recess extending in a direction from the side of a wall opposing the wall provided with the ink supply portion toward the ink supply portion. Alternatively, in an ink tank having no ink holding member, at least a part of inner surfaces of the case is subjected to pear-skin treatment. With those ink tanks, a satisfactory ink supply ability is obtained while achieving a reduction of the tank size.

摘要： An ink tank is to be held detachably on a tank holder provided with a movable lever having a first engaging pawl to engage with a first engagement hole provided for one side wall of the tank holder, and a second engaging pawl to engage with a second engagement hole provided for side wall opposite to the one side wall having the first engagement hole of the tank holder. For this ink tank, the distance S between the outer side face of the base portion of the movable lever of the ink tank and the leading end of the second engaging pawl is set to be larger than the distance between the inner wall faces of the side wall having the first engagement hole of the tank holder and the side wall having the second engagement hole. With the structure thus arranged, unless the ink tank is kept in the normal posture, the ink tank is not allowed to enter the tank holder, hence enabling the user to recognize it easily and prompt him to operate the installation of the ink tank correctly.

摘要： An ink tank is detachably held by a tank holder having an arc shape portion of a specific curvature. This ink tank has also an arc shape portion of a specific curvature, and the arc center of the arc shape portion of the ink tank is in the same position as the arc center of the arc shape portion of the tank holder only when the ink tank is correctly installed on the tank holder. The ink tank is provided with the movable lever having the engagement nail to engage with the tank holder, and the movable lever is provided with the tongue portion on the upper portion of the engagement nail to be operated when the ink tank is removed from the tank holder, and the arc shape portion of the ink tank is the portion of the arc shape formed for the tongue portion. With the structure thus arranged, it becomes possible to facilitate the user to install the ink tank on the tank holder correctly and reliably without exercising any extra force leading to the damage that may be caused to the ink tank.
