ABSTRACT:
An information reader for optically reading information recorded in the form of an array of aligned embossments on a card, comprising a slit plate positioned over a card transport table having two slits, one for directing incident light toward the embossed card and the other for leading to a light-sensitive element series light which has passed past the first named slit and then reflected from a planar surface or raised surface of the embossed card. While the information containing card causes reciprocating motion on the card transport table at a fixed rate, light passed past the last named slit is detected in a storage mode by sequentially scanning the multiple light-sensitive elements so that pattern recognition for the recorded information is carried out by measuring the detection light.
