Data processing system with remote input-output device

Claim 1

IN A DATA PROCESSING SYSTEM WHEREIN THERE ARE A PLURALITY OF INPUT-OUTPUT DEVICES EACH OPERABLE BY A DIFFERENT TICKET AGENT TO COMMUNICATE WITH A CENTRAL COMPUTER, AN INPUT-OUTPUT DEVICE COMPRISING A CARTRIDGE, A PLURALITY OF FILM SLIDES IN SAID CARTRIDGE, EACH SLIDE HAVING DIFFERENT PREDETERMINED INFORMATION THEREON INCLUDING PRINTED INFORMATION AND CODED INFORMATION IN THE FORM OF A PLURALITY OF AREAS ENCODED OPAQUE OR TRANSPARENT IN ACCORDANCE WITH A PREDETERMINED CODE, MEANS FOR SELECTING ONE OF SAID SLIDES INCLUDING MEANS FOR REMOVING A SELECTED SLIDE FROM SAID CARTRIDGE AND PLACING THE SELECTED SLIDE IN A PREDETERMINED POSITION, MEANS FOR PROJECTING LIGHT THROUGH A SELECTED SLIDE, SCREEN MEANS FOR RECEIVING THE PROJECTED PRINTED INFORMATION AND VISUALLY DISPLAYING SAME, EACH OF SAID SLIDES INCLUDING AN OPAQUELY OUTLINED TRANSPARENT SPOT DISPOSED IN A PREDETERMINED LOCATION ON SAID SLIDE, A DIFFERENT LIGHT SENSITIVE DEVICE FOR EACH OF SAID ENCODED AREAS AND ONE FOR SAID TRANSPARENT SPOT, THE LATTER DEVICE RECEIVING LIGHT ONLY WHEN A SELECTED SLIDE IS CORRECTLY POSITIONED, A PLURALITY OF RELAYS THE COILS OF WHICH ARE RESPECTIVELY SERIALLY CONNECTED WITH SAID LIGHT SENSITIVE DEVICES SO AS TO OPERATE THE RESPECTIVE RELAYS WHEN THE ASSOCIATED LIGHT SENSITIVE DEVICE RECEIVES PROJECTED LIGHT, EACH RELAY HAVING A SWITCH OPERATED BY THE RESPECTIVE RELAY COIL, THE TOTAL NUMBER OF RELAY SWITCHES EXCEPT THE ONE ASSOCIATED WITH THE CORRECT POSITIONING LIGHT SENSITIVE DEVICE BEING DIVIDED INTO GROUPS THEREOF WITH EACH SAID GROUP HAVING THE SAME NUMBER OF SAID RELAY SWITCHES, A PLURALITY OF OUTPUT LINES, ONE SWITCH IN EACH OF SAID GROUPS THEREOF BEING CONNECTED TO A DIFFERENT ONE OF SAID OUTPUT LINES, MEANS FOR SEQUENTIALLY ENERGIZING SAID GROUPS OF RELAY SWITCHES TO PROVIDE GIVEN SEQUENTIAL GROUPS OF BINARY SIGNALS ON SAID OUTPUT LINES IN ACCORDANCE WITH WHETHER THE CONNECTED RELAY SWITCH IS OPERATED OR NOT BY THE ASSOCIATED LIGHT SENSITIVE DEVICE, SAID OUTPUT LINES BEING COUPLED TO SAID COMPUTER WHEREBY THE SEQUENTIAL GROUPS OF BINARY SIGNALS ARE OPERATIVE TO IDENTIFY A GIVEN PROGRAM WHICH THE COMPUTER IS TO FOLLOW, SAID PRINTED INFORMATION BEING IN THE FORM OF A TIMETABLE AND DESIGNATING A PLURALITY OF DIFFERENTLY NUMBERED TRIPS AS BETWEEN A PLURALITY OF DIFFERENT ORIGIN AND DESTINATION DESIGNATIONS, A COLUMN OF MANUALLY OPERABLE ORIGIN SWITCH MEANS AND A COLUMN OF MANUALLY OPERABLE DESTINATION SWITCH MEANS ADJACENT SAID SCREEN MEANS, A ROW OF MANUALLY OPERABLE TRIP NUMBER SWITCH MEANS DISPOSED ADJACENT SAID SCREEN MEANS, A GROUP OF MANUALLY OPERABLE TRANSACTION SWITCH MEANS, A GROUP OF MANUALLY OPERABLE SEAT INDICATING SWITCH MEANS, A GROUP OF MANUALLY OPERABLE UNITS DATE INDICATING SWITCH MEANS, A GROUP OF MANUALLY OPERABLE TENS DATE INDICATING SWITCH MEANS, EACH OF SAID SWITCH MEANS INCLUDING AT LEAST FIRST AND SECOND SWITCHES, CODING MEANS COUPLED TO SAID OUTPUT LINES AND HAVING A PLURALITY OF INPUT LINES, ONE SWITCH OF EACH OF SAID SWITCH MEANS IN EACH GROUP THEREOF BEING CONNECTED TO A DIFFERENT ONE OF THE INPUT LINES OF SAID CODING MEANS, SAID SEQUENTIAL ENERGIZING MEANS BEING COUPLED TO SAID FIRST SWITCHES OF EACH GROUP OF SWITCH MEANS FOR SEQUENTIALLY ENERGIZING SAME THEREBY CAUSING OTHER BINARY SIGNALS ON SAID OUTPUT LINES IN ACCORDANCE WITH WHICH OF THE SWITCH MEANS IS OPERATED IN EACH GROUP THEREOF AND IN ACCORDANCE WITH THE CODE PREDETERMINED BY SAID CODING MEANS, THE SECOND SWITCHES OF EACH GROUP OF SWITCH MEANS BEING CONNECTED IN PARALLEL TO FORM GROUPS OF PARALLEL CONNECTED SECOND SWITCHES, EACH GROUP OF SECOND SWITCHES BEING CONNECTED IN SERIES, MEANS INCLUDING THIRD SWITCHES FOR A PREDETERMINED NUMBER OF THE TRANSACTION INDICATING SWITCH MEANS FOR BRIDGING AT LEAST TWO OF THE PARALLEL CONNECTED GROUPS OF SECOND SWITCHES, THE ARRANGEMENT BEING SUCH THAT MANUAL OPERATION OF A PREDETERMINED NUMBER OF SWITCH MEANS EFFECTS A LINE OF CONTINUITY, SAID LINE OF CONTINUITY BEING CONNECTED TO THE RELAY SWITCH ASSOCIATED WITH THE LIGHT SENSITIVE DEVICE RECEIVING LIGHT VIA SAID TRANSPARENT SPOT, AND MEANS COUPLING SAID LAST MENTIONED RELAY SWITCH TO SAID SEQUENTIAL MEANS FOR STARTING OPERATION THEREOF, THE ARRANGEMENT BEING SUCH THAT THE BINARY GROUPS OF SIGNALS SEQUENTIALLY APPEARING ON SAID OUTPUT LINES AS THE RESULT OF MANUAL OPERATION OF GIVEN ONES OF SAID SWITCH MEANS ARE EFFECTIVE AS ADDRESSES FOR SELECTING INFORMATION STORED IN THE COMPUTER, WHILE THE SO SELECTED INFORMATION BEING THEN PROCESSED BY THE COMPUTER IN ACCORDANCE WITH SAID GIVEN PROGRAM, MEANS FOR RECEIVING AND DECODING INFORMATION FROM SAID COMPUTER, AND MEANS FOR INDICATING THE DECODED INFORMATION.
