Abstract: Provided is an automated analysis device with which sufficient reaction process data can be acquired irrespective of the scale of the device, and with which it is possible to ensure freedom of the device configuration. An automated analysis device 100 is provided with: a reaction disk 1 which circumferentially accommodates a plurality of reaction vessels 2; a specimen dispensing mechanism 11 which dispenses a specimen into the reaction vessels 2; a reagent dispensing mechanism 7 which dispenses a reagent into the reaction vessels 2; a measuring unit 4 which measures a reaction process of a mixture of the specimen and the reagent in the reaction vessels 2; and a cleaning mechanism 3 which cleans the reaction vessels 2 after measurement. Further, the automated analysis device 100 includes a controller 21 which controls the drive of the reaction disk 1 such that in one cycle the reaction vessels 2 move by an amount A in the circumferential direction in such a way that N and A are mutually prime, B and C are mutually prime, and the relationship A×B=N×C±1 holds, where N is the total number of reaction vessels 2 accommodated in the reaction disk 1, the reaction disk 1 moves through C (where C>1) rotations+an amount equivalent to one reaction vessel after B (where B>2) cycles, and the number of reaction vessels 2 moved in one cycle is A (where N>A>N/B+1).

Abstract: The present invention comprises: an incubator disk 22 upon which a plurality of reaction containers holding a reaction solution being an analyte and a reagent that have been mixed and reacted are mounted; a immunoassay unit 23 that measures the physical properties of the reaction solution; and a planning unit 103 that determines the order for measurement of analyte requested to be executed by the immunoassay unit 23. Measurement by the immunoassay unit 23 includes items having different measurement times. When measurement of sequence items having the longest measurement time will occur at least a prescribed number of times in a row, said prescribed number being at least two, the planning unit 103 provides at least one empty cycle after measurement has occurred at least the prescribed number of times.

Abstract: An automatic analyzer is capable of transporting a sample at an optimum timing and a method of transporting the sample. An automatic analyzer includes an analysis unit which measures a sample, a transport unit which transports the sample to the analysis unit, and a control unit which controls the analysis unit and the transport unit. A sample is transported to the analysis unit by a time of starting an aspirating operation on the sample by allowing the analysis unit to perform a pre-measurement operation for each measuring method which needs to be performed before aspirating the sample even when the sample is still in the transport unit.
