Abstract

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.

Claims

1. A point-of-sale register system, comprising:

an electronic cash register connected to a central inventory control unit to serve as a terminal device of a point-of-sale system;

a substantially free standing electronic weighing machine electrically connected to said electronic cash register including measuring means for weighing a product, said measuring means being electrically connected to said electronic cash register for supplying to the electronic cash register an electrical signal corresponding to the measured weight of the product, said weighing machine being separate from said cash register and being separable from and removably mounted on an outer surface of a check-out counter;

optical scanner means mounted on top of said weighing machine, in a direction in which gravity acts, said optical scanner means including;

receiving means for receiving a product to be weighed thereon, said receiving means transmitting a weight of a product placed on said receiving means to said measuring means of said weighing machine for measuring the weight of the product placed on said receiving means; and

optical scanning means electrically connected to said electronic cash register for optically scanning a bar code on a product placed on said receiving means and for providing to the electronic cash register an electrical signal corresponding to the scanned bar code; and

wherein the weight of the product placed on said receiving means of said optical scanner means is measured by said measuring means of said weighing machine, and the bar code on the product placed on said receiving means of said optical scanner means is scanned by said optical scanning means.

2. A point-of-sale register system according to claim 1, wherein said weighing machine comprises a weighing pan which is connected to said measuring means, and said optical scanner means is mounted on said weighing pan of said weighing machine, whereby a product placed on said optical scanner means is weighed.

3. A point-of-sale register system according to claim 1, wherein said weighing machine has no weighing pan for receiving a product to be weighed, and wherein said optical scanner means includes a housing means at least part of which is directly supported on said measuring means of said weighing machine, said housing means of said optical scanner means including a receiving portion for receiving thereon a product to be weighed.

4. A point-of-sale register system, comprising:

an electronic cash register connected to a central inventory control unit to serve as a terminal device of a point-of-sale system;

a substantially free standing electronic weighing machine electrically connected to said electronic cash register including measuring means for weighing a product, said measuring means being electricallyconnected to said electronic cash register for supplying to the electronic cash register an electrical signal corresponding to the measured weight of the product, said weighing machine being separate from said cash register and being separable from and removably mounted on an outer surface of a check-out counter, said weighing machine including;

an outer housing means;

said measuring means retained in said outer housing means; and

a weight transmitting member coupled to said measuring means and which has a free end which protrudes from said outer housing means; and

optical scanner means connected to said free end of said weight transmitting member, said optical scanner means including;

receiving means for receiving a product to be weighed thereon, such that a weight of a product placed on said receiving means is transmitted through said weight transmitting member to said measuring means of said weighing machine for measuring the weight of the product placed on said receiving means; and

optical scanning means electrically connected to said electronic cash register for optically scanning a bar code on a product placed on said receiving means and for providing to the electronic cash register an electrical signal corresponding to the scanned bar code; and

wherein the weight of the product placed on said receiving means of said optical scanner means is measured by said measuring means of said weighing machine, and the bar code on the product placed on said receiving means of said optical scanner means is scanned by said optical scanning means.

5. A point-of-sale register system according to claim 4, wherein said weighing machine comprises a weighing pan which is connected to said free end of said weight transmitting member, and said optical scanner means is mounted to said weighing pan of said weighing machine, whereby a product placed on said optical scanner means is weighed.
