POS register system with combined optical scanner and weighing machine

摘要

A point-of-sale register system includes an electronic cash register connected to a central inventory control unit to serve as a terminal device of a point-of-sale system: an optical scanner, which is electrically connected to the cash register, for optically scanning a bar code mounted on a product; and a weighing machine for weighing a product. The optical scanner includes a receiving section for receiving a product to be weighed thereon. The optical scanner is connected to the weighing machine so that the weight of the product placed on the optical scanner is transmitted to a measuring device of the weighing machine for measurement of the weight of the product. If a bar code is on the product which is placed on the receiving section of the optical scanner, the optical scanner scans the bar code of the product.
