BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
The invention relates to a weighing device for the registration of goods in stores, in which each purchased article is identified, subsequently weighed for weight-registration purposes in a weighing receptacle and then taken up, where appropriate, by a carrying container.
2. Description of the Related Art
It is already known to register goods purchased in department stores at self-service goods-registration points and to draw up automatic statements. For this purpose, the customer brings the goods which he/she has purchased, generally in a shopping cart, to a goods-registration point and guides them through a scanning procedure by which bar-coded labels attached to the goods are scanned. Afterwards, the goods are placed into a depositing container, which can also be a further shopping cart and is coupled to a balance. In identifying the goods by the scanning of their labels, the price and weight of the goods are determined. The price of the goods is reported to a till system, the weight information is fed to a comparison device. When the goods are then subsequently weighed, their weight can be compared to the weight information obtained in the identification procedure. If the comparison values agree, then a faulty evaluation or attempted deception can be ruled out.
In the case of this self-service registration of goods, inaccuracies and delays can occur. The balances normally have a weighing accuracy of just a few grams. In the weighing procedure, the time it takes for the balance to settle is often substantially prolonged by different types of external influences, for example accidental nudging, drafts etc.. Moreover, the depositing of the goods, following weighing, in a depositing container belonging to the goods-registration device entails a time loss, since the goods can only thereafter be packed.
It is also already known, instead of a depositing container, to provide carrier bags directly alongside the goods-registration device. However, these have to be taken by the customer from a special storage bay and placed onto the balance. The registered goods can then be filled directly into such a carrier bag. In this case however, the carrier bag has first to be unfolded and erected, thereby substantially prolonging the time spent, particularly where a plurality of carrier bags is used.


SUMMARY OF THE INVENTION

The object of the invention is to define a weighing device for the registration of goods which is insensitive to external influences and avoids delays of the above-described type following weighing, so that the customer is able to leave the goods-registration area directly after the weighing.
This object is achieved by the invention which is a weighing device for the registration of goods in stores, in which each purchased article is identified, subsequently weighed for weight-registration purposes by a floor scale and then taken up, where appropriate, by a carrying container, the floor scale being connected to a support which projects approximately to the waist level and which, close to its upper end, is provided with a suspension device for at least one carrying container which is removable from it.
The weighing receptacle of the weighing device, in one embodiment, is a receiving container filling the interior of a standing container and yet free of the standing container to allow weighing movement therebetween, the suspension device being fitted to the wall of the receiving container. In another embodiment, the weighing receptacle is a shopping container which can be pushed into the interior of the standing container and onto the floor scale, above which shopping container the suspension device is disposed.
The suspension device has at least one cantilever bar from which the carrying container, which is a carrier bag, hangs. Preferably, the suspension device supports a carrier bag pack comprising a plurality of carrier bags connected to one another at predetermined breaking points. In an exemplary embodiment, the suspension device has two b
