Zusammenfassung:The card reader is for reading informations about the testwill-be high pressure gas cylinder written on a punch card. The card contains n x n information bits and n trigger bits which are placed one by one to every n row on upper side of the card. Then, reverse insertion of the card whose side is turned over causes a misreading. The reader includes a discriminating cct. for determining the advance direction of the card, a reversible counter for counting the trigger bits up/downwardly according to the advance direction of the card, and a latch cct. for storing information bits sequentially in unit of row.
