In the figure, three levels of each character are schematically shown. This one query element must be five interrogation devices Al to AS indicated, so that inevitably in a relatively central position with which three different rotational positions of the pneumatic tube post and thus offers a criterion for bushing should be marked at the interrogation location.

Claims (2)

Patent claims: 1. Target identification device for transport containers, in particular pneumatic tube rifles, only with respect to a fixed reference identifier displaceable label and a number of the number of possible displacement positions of the label corresponding to the number of interrogation locations and a small width compared to the label having interrogation devices for the label, ™ characterized gekennz-eUhnet that the Be -, ^ mark (M) in a manner dependent on the Emstelltoleranzen the shift positions and the relative position shifts of the Fördertehälter on passage at the sample location measurements, ₅ is greater than half and less than the entire ride the movable indicator is bernessen, and that the determination of the position of the transport container serving interrogation device (A 1 to AS) each have two interrogation elements (Al Ia Il γ to A 5 /, _M A Sr) for the reference identifier (M) whose distance from one another is less than the width of the reference identifier (M) and larger a ls the difference between the width of the sliding label and the width of the reference label (M) is measured. 2. Target identification device according to claim 1, characterized in that the interrogation devices for the movable mark each contain two query elements at the same distance as that of the query elements door the reference mark from each other and that the query elements for the reference mark via an evaluation circuit in such a way with the query elements for the mark verc · A rhanfferilaeen the conveyor belt is not exactly in Forderbandanla £ «^ aas ^ ^ a fcDene | _Incuding device attached to . ®% XL _stbBchse arranged target magnets and a ^pipe P? ^s "" \ _markers serving markers ais dc β query locations arranged ^ma ^ ^e f ¹ .. ^ '":""has Abfraeeelemente, has"«^""^ possibilities at least partially through these se ^QWl c K _query elements per characteristic Vorsehenije ζ ^ query elements characters bypassed > ™ bitten _{by a} ^ er ^ en.
