Abstract
Disclosed is a computing scale system utilizing an integrated circuit microcomputer for computing the value of a product being weighed and for controlling the operation of a label printer associated therewith. The microcomputer operates with 4-bit words, and there is provided a multiplexing network for multiplexing weight, price, and status information into the microcomputer. Weight readings are made by a bank of photosensors, which read the position of a chart moveable in response to weight on the scale platter. Means are provided for performing a parity check on the data read by the weight photocells, and the data so read is converted from Gray code to BCD code by a table lookup routine. The scale system may print labels having weight and computed value, zero weight and fixed value, or weight and fixed value. The scale has both selectable price and weight dead zone capability with adjustable range. There is a motion detection routine employing a variable settling time.
