Abstract
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.
