ABSTRACT:
Each item in a transaction has a card or ticket having markings signifying its price and category in machine readable form. As each item is purchased, the ticket is inserted into an automatic read-out system. The price and category markings are transduced into signals stored in a first and second buffer storage, respectively. A code converter connected to the second buffer storage operates to furnish a pulse to a corresponding one of a plurality of counters in response to each category signal. The signals in the first buffer storage are added, in turn, by a price adder whose final output therefor shows the total price of all items in the transaction. A grand total adder operates in parallel with the price adder and is cleared after predetermined time periods rather than after each transaction. The signals from the price adder and the grand total adder are supplied through multiplexers to series display and printout devices. A switch is furnished to convert the system to a computer only by disabling the print-out, display, and grand total circuits.
