an extending section that extends in a second direction that is a direction in parallel with the ejection surface and perpendicular to the first direction; and

a protruding section that protrudes upward from one end of the extending section; and

wherein the second tank overlaps the protruding section in the second direction in a state where the first and second casings take the first position.

5. The liquid ejecting device according to claim 3 , wherein the waste-liquid tank has an L-shape formed by a horizontal section and a vertical section, as viewed from the first direction; and

wherein the second tank overlaps the vertical section in a second direction in a state where the first and second casings take the first position, the second direction being a direction in parallel with the ejection surface and perpendicular to the first direction.

6. The liquid ejecting device according to claim 2 , wherein the second tank and the liquid ejecting head are arranged in the first direction, as viewed from a vertical direction; and

wherein the first tank is elongated in the first direction and, at an end at the second tank side, has a connection section that is configured to be connected with the liquid conveying section.

7. The liquid ejecting device according to claim 6 , wherein the first tank and the liquid ejecting head are arranged in a second direction as viewed from the vertical direction, the second direction being a direction in parallel with the ejection surface and perpendicular to the first direction.

8. The liquid ejecting device according to claim 1 , wherein the liquid conveying section comprises:

a hollow needle; and

a hollow-needle moving mechanism configured to move the hollow needle in the first direction between a connection position at which the hollow needle is connected with a connection section of the first tank and a separation position at which the hollow needle is separated from the connection section;

wherein the hollow-needle moving mechanism and the first tank are arranged in the first direction; and

wherein at least part of the hollow-needle moving mechanism overlaps the waste-liquid tank in a vertical direction.

9. The liquid ejecting device according to claim 1 , wherein the first casing comprises a discharge section that is arranged at a position higher than the liquid ejecting head and that is configured to receive a recording medium on which an image has been formed by the liquid ejecting head;

wherein the second casing comprises a medium tray that is arranged at a position lower than the receiving section and that is configured to accommodate a recording medium;

wherein a conveying path is defined within the casing from the medium tray to the discharge section via a space between the supporting section and the ejection surface, the casing accommodating a conveying mechanism configured to convey a recording medium along the conveying path; and

wherein each of the medium tray, the supporting section, the liquid ejecting head, and the discharge section at least partially overlaps the remaining three in a vertical direction.

10. The liquid ejecting device according to claim 9 , wherein the medium tray and the waste-liquid tank are arranged in the first direction.

11. The liquid ejecting device according to claim 9 , wherein the supporting section comprises:

a platen; and

a platen moving mechanism configured to move the platen between a confronting position at which the platen confronts the ejection surface and a retracted position at which the platen fails to confront the ejection surface;

wherein the receiving section comprises:

a confronting member configured to confront the ejection surface when the platen is at the retracted position; and

a confronting-member moving mechanism configured to move the confronting member in the vertical direction between a receiving position at which the receiving section receives liquid from the liquid ejecting head and a standby position that is located lower than the receiving position; and

wherein the platen and the confronting member are arranged between the medium tray and the ejection surface.

12. The liquid ejecting device according to claim 9 , wherein the discharge section has a supporting surface configured to support a recording medium, the supporting surface has one end and another end with respect to a second direction that is a direction in parallel with the ejection surface and perpendicular to the first direction, the one end being located at a position lower than the another end, the one end being located between the first-tank mount section and the ejection surface with respect to the vertical direction; and
