Method and device for inspecting a string of packs. Each of the packs containsdrugs, and consumer data such as patient data are provided on the packs.Specific characteristics of the drugs to be scanned are fed into a centralprocessing unit. These characteristics are compared with the drugs present inthe actual pack. According to the invention, a graphic image of the pack, thedrugs and the patient data is produced and stored. To optimise scanning of agroup of drugs spreading is proposed by means of a resilient cam which rotatesin a plane essentially parallel with the plane of the carrier. Such cam ismounted in a bush and can move resiliently in said bush at right angles to theplane of the carrier and said bush is caused to rotate. It is possible toprovide a number of such constructions adjacent to one another.
