Abstract

L'invention porte sur un dispositif d'analyse, qui comporte un boîtier qui renferme le dispositif d'analyse, et un récipient disposé dans une position prédéterminée dans le boîtier. Le dispositif d'analyse comporte également : un mécanisme de transfert, qui, du fait qu'il est associé au fonctionnement effectué par la section fonctionnelle disposée dans le boîtier, transfère le récipient de la position prédéterminée à une position où le récipient doit être retiré ; et un mécanisme de changement de vitesse qui transmet la quantité de fonctionnement de la section fonctionnelle au mécanisme de transfert par l'augmentation de la vitesse.
