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.
In a control system for a computing scale: a. a counting means for the total cost of an article by use of the input weight and unit price, said counting means including a serial circulating register divided into three input portions for the unit price, the weight and the total price, a transfer portion for the weight of an adding portion for the unit price; said counting means further including a switching circuit for selecting either the circulating operation of said register, an input operation for weight addition or weight subtraction, an input operation for setting the unit price, a shift operation of the register and a clearance operation of the register; and a decimal adder connected to the output of said switching circuit; b. said register having an intermediate terminal, and c. a zero weight discriminator connected to said intermediate terminal for discriminating whether the weight contents at the predetermined portion in said register is zero; d. a circuit for discriminating between a weight and tare condition based on the logic of the zero weight discriminator and the condition of the input weight; and e. a display means for displaying a predetermined range of said register.

Claim 3
Dependent Claim
74 words
A control system as claimed in claim 1 wherein means are provided for supplying two outputs having a certain phase difference from signals detected by a pair of detectors through dark and light striped patterns provided on a pendulum of said computing scale, and a means for forming weight pulses synchronously with timing pulses from a master control circuit, said weight pulses corresponding to the number of stripes which move relative to the pendulum.
Claim 4
Dependent Claim
41 words
A control system as claimed in claim 1 wherein means are provided for electronically memorizing a condition of weight or tare depending on the conditions where addition signals or subtraction signals are supplied when the content of the register is zero.
Claim 5
Dependent Claim
