Abstract:
An electroluminescent display device is provided, in which a substrate of the display is comprised of character electrodes, external connecting means for facilitating connections to external apparatus and a plurality of interconnecting means between the character electrodes and external connecting means. The character electrodes, interconnecting means and external connecting means form one integral unit, with the display device itself being a monolithic structure.

Abstract:
Data indications arranged in rows and columns on a card or other information media are read by use of an arrangement of a plurality of light sources, fiber optic conductors, and light sensors. The light sources are energized to sequentially read one card row at a time activating a selected photocell through unmasked fiber optic conductors. The light sources and conductor ends are aligned such that an aperture in the card will be read as a continuous light beam by a photocell for that position. Means are also provided to insure that the card is properly inserted into the card chamber.
