Abstract
An automatic paper feed device includes a mechanical frame, a paper supply tray mounted to the mechanical frame, at least one motor mounted to one side of the mechanical frame, an upper cover, a stopper mechanism, a paper pressing mechanism, a transmission mechanism, a feed mechanism and a control mechanism. The stopper mechanism includes a blocking element and a torsion spring. The paper pressing mechanism includes a pressing board, at least one pressing roller and an elastic element. The feed mechanism is pivotally mounted to the paper supply tray. The control mechanism controls the motor to rotate, the rotation of the motor drives the transmission mechanism to support or break away from the pressing board to make the pressing board slide upward or downward with respect to the paper supply tray and further abut against or break away from the blocking element.
