Abstract
A device is disclosed for translatorily moving a plate-shaped cup holder, equipped with cups arranged successively in the direction of movement for receiving liquid, to the processing station of an analyzer. The cups are used for mixing viscous body fluid, e.g. blood, with a diluent. Movement of the cup holder and exact positioning of the cups in the processing station are effected in that the cup holder frictionally rests on a driven endless belt, in that an incrementally driven indexing wheel is brought into engagement with the cups, and in that a sensor is arranged for detecting the passage of each cup and determining the indexing position of the indexing wheel in which a cup is located in its processing position.
