1. A sheet sorting apparatus comprising:
a first tray detachable from an apparatus main body;
a second tray arranged below the first tray in a vertical direction;
a discharge unit configured to discharge a sheet toward a first discharge port or a second discharge port, wherein the first discharge port is provided at a position corresponding to the first tray and the second discharge port is provided at a position corresponding to the second tray;
a tray detecting unit configured to detect that the first tray is attached to the apparatus main body; and
a control unit configured to:
receive information about a sheet discharge destination designated by a user, and
determine a discharge port to which the sheet is discharged, based on the received information and a result of the detection made by the tray detecting unit,
wherein the control unit determines the second discharge port to be the discharge port in a case where the second tray is designated in the received information and the first tray is attached, and determines the first discharge port to be the discharge port in a case where the second tray is designated in the received information and the first tray is not attached, and
wherein, upon detecting an attachment of the first tray during discharge of the sheet from the first discharge port to the second tray, the control unit controls the discharge unit to discharge a subsequent sheet from the first discharge port to the first tray regardless of the sheet discharge destination designated by the user.
