Known devices for the opto-electrical scanning of individual cubic or cuboid-shaped packets 10, 19, transported at a distance from one another, have the disadvantage that they do not permit simultaneous scanning of all the packet walls. In the device according to the invention, the conveying distance 26 for transporting the packets is interrupted in the region of a testing station 27. The packets 10, 19 to be examined are moved in this region along an aerodynamic trajectory or falling distance. Consequently, all the walls of the packets 10, 19 to be scanned may be scanned simultaneously on all sides.
