A liquid ejection apparatus including: a first casing; a second casing; and a controller, wherein the first casing is movable between a close position close to the second casing and a distant position farther from the second casing than the close position, the first casing accommodating a head having an ejection face. The second casing accommodates: a support portion having a support face for supporting a recording medium while facing the ejection face; and a moving device configured to move the support portion, such that the support face selectively takes a first state to face the ejection face and a second state not to face the ejection face. A restraining portion restrains movement of the first casing located at the close position, and the controller controls the moving device, such that the support face takes the second state when the controller has received a restraint releasing signal.
