A liquid ejecting apparatus includes a recording head ejecting ink onto a paper; a tray which moves in a direction along a nozzle forming surface in a state where a plurality of units are displaceably supported in a direction approaching and separating from the nozzle forming surface of the recording head; and a cam which is disposed on a moving path of the tray and engages individually with at least two units while the tray moves in a direction along the nozzle forming surface, and makes the units engage individually to be displaced in the direction approaching and separating from the nozzle forming surface.
