A device in equipment for automatically receiving, scanning and handling containers ( 41 ) which are essentially rotationally symmetrical about their longitudinal axes, e.g. bottles or cans of any suitable type of material, the equipment being arranged in such a way that the containers are conveyed and/or rotated in a lying position, by means of a conveyor ( 30 ), through a recognizing chamber ( 10 ) past at least two detectors for scanning information on the properties of the container ( 41 ), from where the scanned information is transferred to a control unit, which decides the conveying path downstream and further handling of the container ( 41 ), the conveyor ( 30 ) being arranged in such a way that the container ( 41 ) is forced at an angle against a supporting device ( 40 ), whereby the container ( 41 ) is simultaneously carried along and rotated about its own longitudinal axis in a helical movement; the device being provided with an image processing system ( 60 ) comprising a camera which is arranged, in cooperation with backlighting from a light plate ( 50 ), to recognize the appearance of the container ( 41 ), a bar code reader ( 70 ) being arranged to scan essentially simultaneously a bar code located on the container ( 41 ), the helical motion of the container ( 41 ) being such that in one turn of the container a complete bar code will be readable to the bar code reader ( 70 ).
