AUTOMATIC ANALYSIS DEVICE

Provided is an automatic analysis device that automatically executes, while analysis is being performed, necessary maintenance without requiring an operator to stop analysis by the device in order toimplement maintenance of a reaction container. Maintenance for keeping the reaction container clean is necessary to secure the reliability of absorbance data, but since it takes 30 minutes or longer to implement the maintenance, a problem of longer operating time arises. This automatic analysis device includes a memory unit for memorizing, in units of days, reaction containers to be cleaned such that all of the reaction containers placed on a reaction disc in a plurality of days are to be cleaned. A control unit performs control such that, in an operation state after samples to be analyzed aredispensed to the reaction containers, the samples to be analyzed in the respective reaction containers are analyzed, and the samples are not dispensed to reaction containers to be cleaned on a day stored in the memory unit, b
