Abstract
Abstract An electronic scale with a CRT display has an input means composed of a manual data input device, weighing means for measuring the weight of an article, a CRT display unit, and a control unit for effecting an arithmetic operation based on signals from the input means and the weighing means and for controlling the CRT display unit. The CRT display unit displays input data from the input means and a result of the arithmetic operation from the control unit. There may be added a timepiece function, a totalling function, or a mode selecting function to the above construction.
