US 6,687,680 B1 · Electronic cash register system

Abstract

Weight data of articles for sale is stored and a total weight is calculated every order. Measured weight of the prepared articles in a package is compared with the calculated total weight. If the measured weight substantially disagrees with the calculated total weight, error information is provided to the operator to correctly package the articles. Comparison may be effected every order number. An addition flag may be further stored with weight data every article to indicate that the article is a target of weight measuring. A non-addition key indicating that the corresponding article is not packaged may be further provided. When the non-addition key is depressed, the weight of the corresponding article is not included in the total weight. The total weight may be printed on the receipt, so that the operator can compare the printed total weight with the measured weight. The total weight may be printed with bar codes. A balance has a bar code reader for comparison. The bar code reader may be provided to the electronic cash register. A controller communicating with the electronic cash register may be further provided at a kitchen for comparison. The order number may be printed on a receipt read by a bar code reader. The controller has a monitor display for informing the error. The difference in weight may be further displayed.
