PROBLEM TO BE SOLVED: To provide an autoanalyzer, equipped with a stirring means using acoustic waves, which can drive a plurality of stirring means when the plurality of stirring means are used or when a new stirring means is added so as to be expanded and in which a control means capable of dealing with the miniaturization and the low cost of the autoanalyzer can be established by solving the problem that, in a conventional control means, piezoelectric elements and drive circuits in the same number are required when the plurality of stirring means are used and that there is a fear when the autoanalyzer is miniaturized and made low-cost. SOLUTION: The autoanalyzer is provided with a stirring means by which a specimen and a reagent are mixed inside a reaction container in a noncontact manner by using the acoustic waves. The autonanalyzer is achieved in such a way that a drive sequence which can drive the plurality of stirring means by one drive circuit is provided at the control means.
