AUTOMATIC ANALYZING DEVICE

PROBLEM TO BE SOLVED: To enable the preliminary treatment of samples in a simple mechanism. SOLUTION: A sample is sucked from the sample cup 24 of an outer circumferential turntable 14 by a probe 34 and dispensed to the reaction tube 4 of an inner circumferential turntable 2. A reagent is also dispensed to the reaction tube 4 from the reagent container 26 of the outer circumferential turntable 14 by the probe 34. After that, by the repeated rotation of the inner turn table 2 at high speed in regular and reverse direction, the reaction solution in the reaction tube 4 is stirred. After the predetermined time of stirring, the reaction solution in the reaction tube 4 is dispensed to an analyzing part 28 and measurement starts.
