<p>PURPOSE:To eliminate automatically noise by providing a circuit that removes a route pattern having no adjoining route pattern and a circuit that removes an oblique branch route pattern to orthogonally crossing coordinate. CONSTITUTION:Coded graphic information stored in a memory 25 is read out by a CPU 24 and inputted to a conditional noise eliminating circuit 26. Noise shown by arrows A, B, G, and H is eliminated first by the conditional noise eliminating circuit 26, and this is further inputted to an unconfitional noise eliminating circuit 27. Noise shown by arrows C, F is eliminated by the unconditional noise eliminating circuit 27. Then, it is again inputted to a conditional noise eliminating circuit 28, and noise show by arrows D, E is eliminated.</p> |
