Claim:
A liquid ejection apparatus, comprising: a platen configured to support a recording medium; a recording head having at least one ejection opening through which liquid is ejected, the recording head being configured to eject the liquid through the at least one ejection opening to record an image on the recording medium supported by the platen; a main tank configured to store the liquid; a sub-tank configured to temporarily store the liquid stored in the main tank, before the liquid is supplied to the recording head; a liquid amount detector configured to detect an amount of the liquid in the sub-tank; a supplier configured to supply the liquid stored in the main tank, to the sub-tank; a first housing configured to hold at least the platen; a second housing configured to hold at least the sub-tank and the recording head and connected to the first housing such that the second housing is pivotable with respect to the first housing so as to be selectively positioned at one of (i) a close position at which the recording head is close to the first housing and (ii) a distant position at which the recording head is farther from the first housing than the recording head located at the close position; a housing position detector configured to detect whether the second housing is located at the close position or the distant position; and a controller configured to, when the housing position detector detects that the second housing is located at the close position, control the supplier to supply the liquid to the sub-tank based on the amount of the liquid which has been detected by the liquid amount detector.
