Abstract
Improved electronic apparatus for weighing, computing a value and printing a label showing the weight, the price per unit weight and the computed value of each of a plurality of successive commodities. An integrated circuit microcomputer is supplied with the article weight from a load cell scale and with the price per unit weight either from a manual keyboard or automatically from a commodity plate in a label printer. The microcomputer includes an arithmetic logic unit, data registers and a sequence controller which is programmed to cause the microcomputer to correct for scale errors, to check for no motion of the scale, to compensate the measured gross weight for any tare weight, to check various interlocks, to compute an article value and to cause a label to be printed for the article. Input data to the microcomputer and output data from the microcomputer is multiplexed through interface circuitry. Weight data from the microcomputer is supplied to a digital indicator and weight, price per unit weight and value data from the microcomputer is supplied to the printer. The keyboard includes a lock switch which must be manually actuated after new price data is supplied to the microcomputer to enable the microcomputer to supply the calculated value data for the weighed commodities to the printer.
