Abstract
The invention concerns an automatic analysis apparatus wherein the liquid sample to be analysed is arranged in a cup (C) containing a ferromagnetic ball (BE) driven in a periodic motion under the effect of a magnetic field. In order to detect the ball (BE) movements representing the physical state of the sample, an electronic camera (CM1 to CM3) is oriented towards the cup (C) while a processor (P) determines, from the cup (C) image, the modifications in the ball (BE) movements. The invention is useful for producing small-size and medium-size automatic appliances.
