ABSTRACT:
A weighing device for handling sales transactions in a retail store, with several functional units, each one among the functional units being linked to at least another one among the functional units by a signal communications system. At least one of unit has a load cell for producing an electric signal proportional to the weight of an object placed on the load cell for weighing. At least one unit has an evaluation unit for forming a weight value expressed in a system of units from the weight signal supplied via the given signal communications system. At least one unit has a display unit for displaying the weight value and a total price of the object supplied via the given signal communications system. Also, at least one unit has a control unit for memorizing an article number and an associated unit price of the object and for controlling the operation of the weighing device so as to calculate the total price by multiplication of the unit price with the weight value after the article number is entered. At least two among the functional units having the load cell, the evaluation unit, the display unit, and the control unit are spatially separated from each other in the retail store, and their signal communications system, which serves to maintain the flow of signals connected with the handling of the sales transactions, is executed wirelessly.
