Claims (1)

[Scope of utility model registration request] A weighing signal register that stores a weighing signal proportional to the weight of the object to be weighed; a proportionality constant register that stores a proportionality constant of the weighing signal to the weight of the object to be weighed; and a value stored in the weighing signal register and the proportionality constant. A first multiplier that multiplies the value stored in the register, a weight register that stores the multiplication result, a unit price register that stores the price per unit weight of the object to be weighed, and the value stored in the unit price register and the above. In a price scale comprising a second multiplier that multiplies the value stored in the weight register, and a price register that stores the multiplication result; a price register for verification that stores the value stored in the price register; and a price register that stores the value stored in the price register; and a first comparison which compares a divisor register that stores the stored value of one of the unit price registers with the stored value of the other of the verification price register and the unit price register, and issues a signal if the two comparison values are different. a weight register for verification that stores the value stored in the weight register; a second divider that divides the stored value by either the value stored in the weighing signal register or the value stored in the proportionality constant register; a second comparator that compares the division result with the other of the value stored in the measurement signal register and the value stored in the proportionality constant register and issues a signal if the two comparison values differ; and the first and second comparisons. A toll scale calculation verification device comprising an OR circuit which emits an output when the output of the toll scale is input and makes the toll scale inoperable.
