Abstract
A paper tray includes a first plate and an extension mechanism. The first plate includes a receiving space and a guiding groove. The extension mechanism includes a second plate, a paper stopper, and an elastic element. When the extension mechanism is moved to a first position in a direction opposite to the first plate and the paper stopper is rotated relative to the second plate in a first direction, the elastic element is pushed by an end of the paper stopper. Consequently, the elastic element generates an elastic potential energy. When the paper stopper is rotated relative to the second plate in a second direction, the elastic potential energy drives movement of the elastic element in a direction facing the first plate, so that the second plate is moved to a second position and the extension mechanism is automatically restored to the receiving space.
