Abstract
A liquid ejecting device is provided. A main tank stores liquid. A sub-tank includes a variable volume liquid chamber that stores the liquid supplied from the main tank. A head ejects the liquid supplied from the sub-tank. A carriage is movable to reciprocate the sub-tank and the head. A first engagement member is provided in the sub-tank and is movable to expand the volume of the liquid chamber. A second engagement member engages with the first engagement member and moves the first engagement member. The liquid is supplied from the main tank to the sub-tank when the first engagement member is moved by the second engagement member to expand the volume of the liquid chamber.
