Abstract: An automatic analysis apparatus includes: a driving rotor configured such that a rotational center extends vertically; a reaction disk mounted on the driving rotor; a plurality of reaction cells installed in the reaction disk and configured to form a circular row concentric with the driving rotor; a circular reaction chamber configured to accommodate the reaction cells; and a guide configured to guide an elevation trajectory of the reaction disk with respect to the driving rotor.

Abstract: A maintenance method in an automatic analysis apparatus includes: a recognition step of recognizing an integrated rack 301A, 301B, 301C mounted with a cleaning solution container containing a cleaning solution, and a calibrator container containing a calibrator or a QC specimen container containing a QC specimen containing a sample having a known concentration; a cleaning solution supply step of aspirating a cleaning solution; and a supply step of aspirating the calibrator or aspirating the QC specimen, in which the cleaning solution supply step and the supply step are continuously performed from the cleaning solution container and the calibrator container or the QC specimen container mounted on the integrated rack 301A, 301B, 301C. Accordingly, an automatic analysis apparatus and a maintenance method in the automatic analysis apparatus that can reduce a burden on a user in calibration and the like during maintenance are provided.

Abstract: To save a space and to reduce a burden of a user due to an exchange work of a reagent having large capacitance. A reagent mounting mechanism (14) including a reagent mounting part (15) serving as an installation location of containers (9a, 9b, 9c, and 19) for holding a solution such as a reagent is provided in a side surface of an analysis unit (100) to be drawable. An RFID reader (10) for reading an RFID tag (13) installed in the containers (9a, 9b, 9c, and 19) is arranged in a position matching the RFID tag (13) when the containers (9a, 9b, 9c, and 19) are placed on the reagent mounting part (15) of the drawn reagent mounting mechanism (14).

Abstract: A detergent reservoir reserves detergent for cleaning of a sample probe and includes a cleaning liquid supply port, a detergent supply port, and a waste liquid port When a predetermined condition for execution of cleaning of the detergent reservoir is not satisfied, and a remaining amount of the detergent reserved in the detergent reservoir is a predetermined amount or less, a pump is operated to increase the remaining amount of the detergent to the predetermined amount; and when the predetermined condition for execution of cleaning of the detergent reservoir is satisfied, a solenoid valve is opened to dispose of the detergent in the detergent reservoir. Then, after the detergent in the detergent reservoir is disposed of, the solenoid valve is closed, and a pump is operated to supply cleaning liquid to the detergent reservoir.
