System for controlling a computing scale

Abstract

Abstract A controlling system for a computing scale. The system has a circulating register formed in a series having desired figure of desired bits. An input signal selecting and changing circuit is connected to the circulating register, and a decimal adding circuit is connected to the input signal selecting and changing circuit. The circulating register, input signal selecting and changing circuit and decimal adding circuit form an amount cost counting means which is operated according to input signals of weight and unit cost. The circulating register has an intermediate terminal at a predetermined position thereof, a zero weight discriminating circuit and a weight subtraction discriminating circuit which are connected to the intermediate terminal of the circulating register. A weight and packing discriminating circuit and a displaying means are provided, the operation of the weight and packing discriminating circuit being changed correspondingly to output signals from the zero weight discriminating circuit and from the weight subtraction discriminating circuit. The contents thereof are memorized in the circulating shift register. A calculating operation of the cost is performed within the circulating shift register synchronized with a timing pulse by the amount cost counting means, and the contents of a certain range of the circulating shift register are displayed by the displaying means.
