ABSTRACT:
Fiber optic cables are employed to convert punched card type of input infation to an alpha-numeric visual display. Separate groups of the fiber optic cables have first terminal ends positioned in an aperture area corresponding to the punched card aperture area. The second terminal ends of each group of fiber optic cables defines a single segment of an alpha-numeric character in a uniform multi-segment format. When a punched card or punched tape type of input information is inserted between a suitable source of light energy and the first terminal ends of the groups of fiber optic cables, those aperture areas which are punched out permit the transmission of light from the light source to the visual display, thereby illuminating corresponding segments of characters in the uniform multi-segment format at a display plane and converting the punched card information to alpha-numeric visual display.
