- a reagent holding unit is installed next to the analysis unit as a separate unit from the automatic analyzer, and after the RFID tag information is read by the reagent information reading mechanism, the reagent bottle is read by the reagent It is described that the reagent is carried out to the analyzing section side by a reagent discharging mechanism capable of changing the transport direction of the reagent.
- two reagent disks are installed side by side in the analysis section, a reagent bottle is gripped by a reagent transport mechanism, passes near the center of the two reagent disks, and the reagent transport mechanism discharges the reagent.
- a reagent bottle ejected from the mechanism is transported by movement in the X direction or the XY direction with respect to a predesignated reagent disk.
- the reagent transport mechanism is installed on the right side of the analysis section, and the reagent bottle is transported on a straight line connecting the reagent gripping position in front of the analysis section and two reagent disks arranged vertically in the analysis section.

- Patent Literature 1 since the reagent holding unit is provided separately from the analysis section, the installation area of the device is large. Furthermore, since the reagent transport mechanism passes through the vicinity of the center of the reagent disk, when transporting the reagent bottle, the dispensing mechanism installed in the analysis unit is stopped to secure a path through which the reagent transport mechanism can pass before the reagent is transported. Since the bottle needs to be transported, the waiting time of the dispensing mechanism for loading and unloading becomes long, so there is room for improvement.
- the reagent transport mechanism is installed on the right side where interference with the pipetting mechanism in the analysis unit does not occur. There is the problem of growing up. Furthermore, since the reagent gripping position and the transport distance to the two reagent disks are different, transporting to the reagent disk on the long distance side (back side of the analysis unit) takes a long time.
