Filed: 1966-12-22
Abstract: 1,113,880. Card readers. TATEISI ELECTRONICS CO. 22 Dec., 1966 [29 Dec., 1965], No. 57419/66. Heading G4M. A card has a series of guide marks h, data marks H and distinguishing marks H 1'  H 2 , the latter enabling the orientation of the card (four possibilities) as it is inserted in reader P to be identified, and the reader includes means for routing signals derived from phototransistors P 1 -P 6  to the correct inputs of collating circuit M irrespectively of the orientation of the card. Phototransistor P 0  holds F 1  set until a card is inserted, AND gates A 2'  A 4 -A 12  being enabled. With the card oriented as shown, P 2  senses hole H 1  and a pulse passes via A 4 , OR gate R 3  and AND gate A 13  to reset F 2 , whereby AND gate A 14  is enabled to pass subsequent pulses generated by P 1  sensing holes h to counter C 1  which energizes inputs 1R to 7R in turn prior to each data column on the card being sensed. The data holes H in 2-out-of-5 are sensed by P 2 -P 6  and the resulting signals are passed by A 4 , A 6 -A 12  and R 3 -R 7  respectively to circuit M. If the card is inserted with edge ED uppermost and edge EL leading, H 1  is sensed by P 5  and this resets F 1  via D 2  and inhibit gate INH, the latter being open except when C 1  or C 2  is not in the zero state. Gates A 1 -A 11  are thereby enabled, holes h sensed by P 6  step C 1  via A 11 , R 2  and A 14 , the latter being enabled by the sensing of H 1  as before, and the signals derived by P 1 -P 5  sensing holes H are transposed to R 7 -R 3  respectively. If the card is inserted with EU uppermost but ER leading, H 2  is sensed by P 4  and F 3  is reset via A 8 , R 5  and A 15  so that subsequently, when holes h are sensed by P 1 , counter C 2  is stepped via A 2 , R 2  and A 16 . The data columns are sensed in reverse order in this case, so counter C 2  energizes the inputs 1R-7R in the reverse order. In the remaining case, ED uppermost and ER leading, H 2  is sensed by P 3 , so that F 1  is reset to transpose the data signals to R 7 -R 3  respectively and C 2  is made active va A 5 , R 5 , A 15  and F 3 . The card may be a credit card and be used for operating an automatic barrier at a railway station, circuit M producing an output U if the card is valid and an output V if it is invalid.
