  • Publication number: 20160375690
    Abstract: There is provided a liquid consuming apparatus including a casing, a liquid consuming section, and a tank. The tank includes a box-shaped body having a light-transmitting property and having five walls and a partition wall; a film adhered to rear end portions of the walls; and a positioning section disposed at least on an outer surface of each of the upper and lower walls, or of each of the right and left walls. In a state that the liquid consuming apparatus is placed on a horizontal plane, the box-shaped body is positioned at a posture at which the positioning section is brought into contact with the casing to thereby allow the front wall to be exposed from a side surface of the casing which extends in a direction crossing the horizontal plane, and at which the rear end portions are located inside the casing.
