Abstract: An electric paper tray includes a base, a paper holding element pivotally mounted to at least one side of the base, a power unit arranged at the base, and a lifting module connected between the paper holding element and the power unit. The lifting module is movably mounted under the paper holding element. When the lifting module is driven by the power unit to move to a first position, with respect to the base, the lifting module drives the paper holding element to make the paper holding element rotate to a closed position, when the lifting module is driven by the power unit to move to a second position, with respect to the base, the lifting module drives the paper holding element to make the paper holding element rotate to an opened position.
