Abstract
A medium stack tray comprises a stacking member that stacks a sheet medium and is configured to be wound in a roll, a winding mechanism that winds the stacking member, a regulating mechanism that regulates the stacking member being pulled out to be wound by the winding mechanism, and a releasing mechanism that releases regulation for winding the stacking member by the regulating mechanism. In the stacking member being pulled out, at least a portion of a cross section thereof, in a perpendicular direction to a pull-out direction of the stacking member, has a curved shape. Alternatively, the stacking member is configured to have greater minimum area moment of inertia of a cross section when pulled out, than when wound up.
