Device for registering goods
First Claim
1. A device for registering goods at a self-service cash register system comprising:
- a conveying device configured to convey goods in a predefined conveying direction, the conveying device including a first conveyor belt and a third conveyor belt each having a support surface, a second conveyor belt at least partially arranged over the support surface of the first and third conveyor belts, the second conveyor belt configured to support goods seated thereon for conveying the goods in the conveying direction, the second conveyor belt surrounds both the first and the third belts; and
at least one scanning device locally fixed at the conveying device configured to register machine-readable codes furnished for the goods and affixed thereto, the scanning device arranged after the first belt and before the third belt in the conveying direction, and including at least one source for emitting optical radiation towards the conveying device, and at least one detector for both receiving the radiation reflected from the goods lying on the conveying device and generating a signal matching the intensity of the reflected radiation;
wherein the second conveyor belt is a net with openings extending in directions orthogonal to each other with individual opening sizes smaller than the machine-readable codes and is configured to permit the passage of optical radiation therethrough from the source;
wherein the first and the third conveyor belts are configured to circulate around rollers to guide the second belt around the scanning device;
wherein the first, second, and third conveyor belts are configured to move at identical speeds and are in a common plane extending in the conveying direction; and
wherein the device is operable to register the goods by reading the machine-readable codes affixed to the goods by the scanning device through the net as the goods are conveyed in the conveying direction.

Abstract
A device for registering goods in a self-service cash register system is proposed, comprising a conveying device (2) for conveying goods in a predefined conveying direction (3), with at least one conveying means (4, 5, 10) of the conveying device onto which the goods can be placed for conveying, with at least one scanning device (1) arranged in a locally fixed manner at the conveying device (2) for registering machine-readable codes with which the goods are equipped, with at least one source for emitting optical radiation in the direction of the conveying device and at least one detector for receiving the radiation reflected by the goods lying on the conveying device and for generating a signal that corresponds to the intensity of the reflected radiation, wherein the conveying means (10) is pervious to the optical radiation from the source at least in some sections.
