4. The liquid consumption device according to claim 1, [ A liquid consumption device, comprising:
a tank having an inner space, the inner space defined by a plurality of outer walls including a lower outer wall and an upper outer wall opposite to the lower outer wall, the inner space being externally accessible via an inlet, in the upper outer wall of the plurality of outer walls, and via an outlet; and
a liquid consumption part connected to the outlet,
wherein, in a usage attitude, the upper outer wall is a top wall of the tank,
wherein the tank has a first inner wall which extends, in a first direction, in a state where the tank takes the usage attitude, from a first outer wall of the plurality of outer walls toward a second outer wall, ]
wherein, in a state where the liquid consumption device [ tank ] takes the usage attitude, the first inner wall has an upper surface tilted downward toward the one direction from the outer wall [ that is inclined away from the upper outer wall as distance from the first outer wall increases,
wherein the first inner wall partitions the inner space into a first space in which the inlet is located and a second space in which the outlet is located, the first inner wall unobstructedly facing the inlet and spaced from the upper outer wall via the first space, the first inner wall at least partially defining a first communication hole through which the first space and the second space communicate with each other,
wherein, the second space comprises a third space, which is defined in part by the first inner wall and the first outer wall and is located below a lowermost portion of the first communication hole when the tank is positioned in a first non-usage attitude, which is defined as a first counterclockwise orientation of the tank having been rotated counterclockwise about a horizontal axis by an angle from larger than 0 degree to 90 degrees from the usage attitude, wherein the horizontal axis is perpendicular to a vertical direction,
wherein the second space further comprises, when in the usage attitude, a fourth space partially overlapping the third space and extending between the lower outer wall and the first inner wall,
wherein, when in the first counterclockwise orientation rotated counterclockwise from the usage attitude, the third space is configured to store a particular amount of liquid, and
wherein, when in the usage attitude, the fourth space is configured to store the particular amount of liquid] .
