Abstract: A paper feeding tray includes a base body, two through holes, two paper guiding elements pivotally disposed in the two through holes, and two elastic elements. The two through holes penetrate through the base body along an up-down direction. An inner portion of a shaft hole of a front inner wall of each through hole extends inward and then expands transversely to form an eccentric hole. Two sides of an inner portion of a shaft which is protruded from a front surface of each paper guiding element transversely extend oppositely to form an eccentric element. The two eccentric elements of the two paper guiding elements are rotatably accommodated in the two eccentric holes of the two through holes. The two elastic elements abut against the two eccentric elements.
