1. A medium discharge device comprising:
a discharge unit configured to discharge, in a discharge direction, a medium on which recording is performed;
a pair of support portions configured to support the medium discharged by the discharge unit, the pair of support portions being configured to open and close by moving in mutually opposite directions in a width direction intersecting the discharge direction; and
a loading tray at which the medium dropped by opening the pair of support portions is loaded, the loading tray being configured to be displaced in a loading direction, wherein
a control unit configured to control an operation of opening and closing the pair of support portions and an operation of displacing the loading tray in the loading direction is configured to acquire curl information including information regarding a degree of curl of the medium, and
the control unit sets, based on the curl information,
a position of the loading tray in the loading direction when the pair of support portions are opened and closed to a first position in a case where a condition when the pair of support portions are opened and closed is a first condition, and
the position of the loading tray in the loading direction when the pair of support portions are opened and closed to a second position lower than the first position in a case where the condition when the pair of support portions are opened and closed is a second condition on which the medium curls more easily than on the first condition.
