Nucleic acid analyzer, automatic analyzer, and analysis method

An automatic analyzer configured to execute an analytical reaction requiring two or more temperature changes in the process of preparing reaction samples, said analyzer comprising:

• a plurality of reaction containers, each of the plurality of reaction containers containing one of the reaction samples;
• a plurality of incubation mechanisms, each of the plurality of incubation mechanisms configured to control the temperatures of the plurality of reaction containers;
• a transport mechanism configured to transport each of the plurality of reaction containers;
• a control mechanism configured to control the transport mechanism;
• a rotary disc configured to rotate the plurality of the reaction containers;
• a detector disposed around a circumference of the rotary disc and configured to detect fluorescence emitted from each of the plurality of reaction containers rotating by the rotary disc;
• and
• an analytical mechanism configured to perform an analysis of each of the reaction samples based on the emission of the fluorescence,
• wherein:
• the control mechanism is configured to control the transport mechanism to continuously transport each of the plurality of reaction containers within a given period of time and in a given order from one of the plurality of incubation mechanisms to another one of the plurality of incubation mechanisms in which two or more different temperature levels are set, and
• the transport mechanism is configured to transport each one of the plurality of reaction containers to the rotary disc continuously, after the given period of time.
