RAN 4090/214 Abstract A device for identifying a container carrier (11) for an automatic analytical apparatus, the carrier having an array of fields (21-28) on a flange (12), some of the fields being transparent and the other fields being opaque, the device also containing an electro- optical arrangement to detect whether each of the fields is transparent or opaque. In order to increase the reliability of the device in the identification of the container carriers, it is characterized in that the electro-optical arrangement comprises the following components: (a) a light source (14), (b) a plurality of light receivers (31-38) each associated with one of the fields (21 28), (c) a light guide (15) apt to receive a light beam generated by the light source and to derive from said beam a plurality of rays of light (41-48) each directed towards one of the fields (21- 28) and reaching their associated light receivers through the transparent fields.
