AUTOMATIC ANALYZER

An automatic analyzer has a reagent carrying mechanism capable of reducing a burden on an operator, which can reduce degradation in throughput of the device and an installation area to be smaller compared to the related art. The automatic analyzer includes a plurality of reagent dispensing mechanisms that dispense a reagent from a reagent bottle into a reaction container. A plurality of reagent disks store the reagent bottles. The reagent carrying-in positions are provided in the respective reagent disks to put in the reagent bottles to the respective reagent disks. A carrying mechanism that carries the reagent bottles between the respective reagent carrying-in positions and a reagent bottle gripping position, in which when an automatic analyzer is viewed from a vertically upper side, the reagent bottle gripping position being positioned between the reagent carrying-in positions on a device front side of the automatic analyzer.
