Abstract

There is provided a liquid discharge apparatus which includes a tank including a liquid storage chamber, an inlet, a liquid lead-out channel, and an atmosphere communication channel, a conveyance mechanism, a carriage, and a head. A lower end of the inlet is positioned at a lower side of the nozzles, and the liquid storage chamber is arranged at a position shifted from the nozzles, in a first-direction side of the front-rear direction, and shifted from the conveyance route, to a second-direction side of the left-right direction. The liquid storage chamber is connected to the liquid outflow channel at a position on a lower side of a center in a up-down direction of the liquid storage chamber, and in the first direction from a center in the front-rear direction of the liquid storage chamber, and on the second-direction side of a center in the left-right direction of the liquid storage chamber.

Claims (14)

1. A tank, comprising:

a liquid storage chamber configured to store a liquid; and

an outlet configured to flow out the liquid stored in the liquid storage chamber,

wherein the liquid storage chamber includes a base portion and a protruding portion, the base portion includes a first lateral wall and a second lateral wall which faces the first lateral wall in a left-right direction, the protruding portion protrudes from the second lateral wall of the base portion in a direction away from the first lateral wall in the left-right direction, and the left-right direction is defined based on a usable posture in which the tank is disposed such that a lower surface of the liquid storage chamber is located below an upper surface of the liquid storage chamber, and

wherein a distance between the outlet and the second lateral wall in the left-right direction is smaller than a distance between the outlet and the first lateral wall in the left-right direction.

2. The tank according to claim 1 , wherein a volume of one side of a center in the left-right direction of the liquid storage chamber is smaller than a volume of an other side of the center in the left-right direction of the liquid storage chamber, wherein the second lateral wall is located at the one side with respect to the first lateral wall in the left right direction.

3. The tank according to claim 1 , wherein the protruding portion of the liquid storage chamber is configured to store a part of the liquid.

4. The tank according to claim 1 , further comprises an inlet configured to flow in the liquid into the liquid storage chamber,

wherein the protruding portion is located below the inlet in an up-down direction.

5. The tank according to claim 2 , wherein the protruding portion includes a third lateral wall defining the liquid storage chamber in the left-right direction,

wherein a volume of the one side, of the liquid storage chamber, from a center between the first lateral wall and the third lateral wall in the left-right direction is smaller than a volume of the other side, of the liquid storage chamber, from the center between the first lateral wall and the third lateral wall in the left-right direction.

6. The tank according to claim 1 , wherein the tank comprises a plurality of other liquid storage chambers arranged side by side in the left-right direction, wherein the liquid storage chamber is located at one side of the plurality of other liquid chambers in the left-right direction, wherein the second lateral wall is located at the one side with respect to the first lateral wall in the left right direction,

wherein the protruding portion of the liquid storage chamber protrudes toward the one side in the left-right direction such that the protruding portion does not face one of the plurality of other liquid storage chambers in the left-right direction.

7. The tank according to claim 1 , wherein the outlet is located on the second lateral wall of the base portion of the liquid storage chamber.
