Sample measuring apparatus and method of circulating air in reagent storage

A sample measuring apparatus comprising:

• a measuring unit that measures a sample by using a reagent stored in a reagent container;
• a reagent storage that includes a case defining an inner space that stores the reagent container;
• a reagent container holder arranged in the inner space of the reagent storage and that holds the reagent container;
• a rotation table that is arranged in the inner space of the reagent storage;
• a fin that is provided in the inner space of the reagent storage and is provided as attached to an underside of the rotation table and that circulates air in the reagent storage;
• and
• a driving unit, wherein
• the reagent container holder comprises a first reagent container holder and a second reagent container holder that is arranged around the first reagent container holder, wherein the rotation table supports the second reagent container holder,
• the driving unit comprises a first driving unit comprising a first motor that drives the first reagent container holder to rotate and a second driving unit comprising a second motor that drives the rotation table that supports the second reagent container holder and the fin to rotate so as to circulate, by the fin, the air in the reagent storage, and
• the rotation table includes multiple openings such that the air passes through the multiple openings between a region below the rotation table and a region above the rotation table.
