High speed data display and recording apparatus

Claim 1

IN A HIGH SPEED RECORDER FOR PRESENTING CHARACTERS IN LINE FORMATION ON AN IMAGE RECEIVING MEDIUM, THE COMBINATION OF A MATRIX PLATE WITH LIGHT TRANSMITTING CHARACTERS OR SIGNS ARRANGED IN ROW AND COLUMN FORMATION, EACH ROW CONTAINING THE SAME CHARACTER REGULARLY SPACED AND REPEATED AS MANY TIMES AS THERE MAY BE CHARACTERS IN THE LINE AND EACH COLUMN CONTAINING DIFFERENT CHARACTERS, A LENS POSITIONED TO MAKE AN IMAGE OF SAID PLATE ON THE IMAGE RECEIVING MEDIUM, A PAIR OF PARALLEL REFLECTING SURFACES BETWEEN SAID LENS AND SAID IMAGE RECEIVING MEDIUM POSITIONED SO THAT THE OPTICAL AXIS OF THE LENS IS SUBSTANTIALLY AT EQUAL DISTANCES FROM SAID REFLECTING SURFACES, SASID REFLECTING SURFACES BEING SUBSTANTIALLY PERPENDICULAR TO THE COLUMNS OF THE SAID MATRIX AND SPACED IN RELATION TO THE DISTANCE BETWEEN CONSECUTIVE CHARACTERS IN EACH COLUMN, A SINGLE SOURCE OF LIGHT COMPRISED OF A CATHODE RAY OSCILLOSCOPE WITH A CONTROL CIRCUIT PRODUCING A LIGHT SPOT OT APPROPRIATE DIMENSION TO ILLUMINATE A SELECTED LIGHT TRANSMITTING CHARACTER IN EACH OF THE VARIOUS COLUMNS IN SUCCESSION, WHEREBY THROUGH THE ACTION OF THE LENS AND OF MULTIPLE REFLECTIONS BETWEEN THE REFLECTING SURFACES, THE ILLUMINATED CHARACTERS ARE PROJECTED ON THE IMAGE RECEIVING MEDIUM ON A FIXED LINE AT POSITIONS DETERMINED BY THE COLUMNS CONTAINING THE SELECTED LIGHT TRANSMITTING CHARACTERS, AND MEANS TO MOVE THE IMAGE RECEIVING MEDIUM CONTINUOUSLY IN A DIRECTION TRANSVERSE TO SAID LINE.
