Abstract
Abstract APPARATUS FOR GENERATING PATTERNS ON A RECEIVING MEDIUM COMPRISES A BEAM SOURCE ASSEMBLY WHEREIN THE PATTERNS TO BE GENERATED ARE "PAINTED" AS COMBINATIONS OF SUCCESSIVE STROKES BY THE BEAM. THE BEAM FROM EACH STROKE IS SPLIT TO FOLLOW TWO PATHS, ONE TOWARD THE RECEIVING MEDIUM AND THE OTHER TOWARD A TRANSDUCER ASSEMBLY, WHICH GENERATES SIGNALS AS THE BEAM MOVES OVER IT. THESE SIGNALS, WHICH EFFECTIVELY INDICATE THE INSTANTANEOUS POSITION OF THE BEAM, ARE COMPARED WITH CODED COMBINATIONS OF SIGNALS SPECIFYING THE DESIRED TERMINAL POSITIONS OF THE BEAM TO GENERATE CONTROL SIGNALS WHICH CONTROL THE DEFLECTION OF THE BEAM WHICH CONTROL THE DEFLECTION OF THE ELECTRON BEAM OF THE CATHODE RAY TUBE. FURTHER MEANS ARE SHOWN WHEREIN THE LIGHT DIRECTED TOWARD THE RECORD CAN BE SELECTIVELY EXPOSED.
