ABSTRACT:
Any numeric display (0-9) can be obtained by rotating the three endless belts to position the indicia on each to combine with the others to form the desired numeral. Each belt has a plurality of faces or display areas along its length and is driven by a separate motor until a sensing means determines the proper face is in display position. The belts follow a serpentine path to permit the belts to be housed in a frame about as high as the numeric readout. A change in the readout can be programmed and initiated at a remote location.
