ABSTRACT:
In an apparatus and a method for optically determining the position of products by means of light-sensitive sensors on a background moving relative thereto such as a conveyor belt, at least one light source radiating light onto the conveyor belt is arranged along at least one scanning line extending transversely with respect to the direction of movement. At least one row of light-sensitive sensors, which row is arranged along at least one scanning line, is operable to register a light effect caused by products passing between the light source and the sensors.
