Abstract: 1,255,521. Keyboard entry machine. AMERICAN TOTALISATOR CO. Inc. 25 April, 1969 [26 April, 1968], No. 21377/69. Heading G4T. An apparatus for recording transactions (e.g. a point of sale machine) comprises a keyboard having an array of keys 6-26, each of which is selectable for entry of information in more than one step of a transaction, means 54 to 70 for effecting recording of information entered in said keyboard, visual indicating means (e.g. lamps behind keys 54 to 70 and area 28) for sequentially identifying classes of information to be entered in said keyboard, and means controlled by the operation of keys 16, 27 in one of said steps for controlling the sequence of identification by said visual indicating means in subsequent steps of a transaction. Also provided is a calculator for adding, subtracting, sub-totalling, and totalling numerical data entered in different steps, a printer for issuing duplicated sales slips having transaction data thereon, and a cash drawer. Operation.-An area 30 is illuminated if a supply of sales slips is present (Fig. 1) and the clerk presses any key in column 26 to indicate the type of transaction. All the keys on the board are connected through a D.C. electric circuit composed mainly of relays with some diodes and one SCR, the circuitry lighting lamps behind the buttons 54 to 70 and the area 28 and controlling operations. The key 58 is illuminated, the clerk's number entered on columns 6 to 14, and key 58 then pressed to effect recording of the number. The printer then prints data, store number, register number and transaction number on the sales slips. Depending on the transaction, the clerk has a number of alternatives as shown on Fig. 9. If it is a credit sale, the appropriate key in column 26 will have been pressed at the beginning, and now the customer's account number is entered in columns 6 to 14, key 60 pressed and then the unit control number and/or merchandise number entered in sequence on any combination of columns 6 to 26. The last operation is repeated for each item as indicated by the closed loop on Fig. 9 returning to the enter unit control number or merchandise box. For each cycle the printer and calculator operate and the appropriate keys are lit up in sequence. At the end of sales unit entries, subtotal key 66 may be pressed in order to add on sales tax, state tax, employees' rebate &c. The calculator adds the sales items then the entered tax. Alternatively, if the customer tenders a deposit, subtraction occurs in the calculator. At the end a total is taken and a sales slip issues having full sales data thereon (Fig. 8, not shown). Numerous alternatives are provided on the flow chart of Fig. 9, and in each ease the appropriate sequence of keys is lit up. At the end of a day a cash count is needed and key 4 in column 26 is pressed. The keys in column 6 now have different meanings corresponding to coins, currency, checks &c. The amounts of each in the case drawer are entered on columns 6 to 14 and the appropriate key in column 6 depressed. At the end, depression of total key 72 causes a sales and cash drawer account slip to be issued. The calculator and printer are of the modified Clary type and may be linked to a central computer, the computer holding lists of unacceptable credit account numbers.
