PURPOSE: A device for automatically supplying packing box boards is provided to reduce the size of a packing box board supply device, to adjust the distance between two board stacking racks depending on the sort of a packing box board, and to smoothly supply the packing box boards by periodically hitting the packing box boards. CONSTITUTION: Two board stacking racks(10) are placed at both sides of a packing box board. A drum(18) is used as a middle supporter. The drum is driven by a motor(19). The drum periodically aligns the packing box boards by using a hitting bar. Thus, two-step divided stacking of packing box boards is possible and the packing box boards are supplied in the lengthwise direction. A distance adjusting motor drives a screw bar(15) combined to the lower end portions of the board stacking racks. A guide bar(17) is placed parallel to the screw bar. By using the screw motion, the distance between the board stacking racks is adjusted.
