11. An automatic analyzing apparatus comprising:
a reagent storage configured to contain a plurality of reagent containers; and
a reagent dispensing probe configured to aspirate a reagent contained in at least one of the reagent containers, wherein
the reagent storage comprises:
a housing including a first hole connecting an inside and an outside of the housing;
a placement table provided in the housing on which the reagent containers are placed, the placement table dividing a space in the housing into a first space which is below the placement table and a second space which is above the placement table, the first hole being provided to face the first space;
a cover having a probe second hole through which the reagent dispensing probe is inserted and configured to cover an opening of the housing;
a fan arranged above the placement table and configured to send air upward thereat;
a first convection separating plate arranged so as to surround the fan; and
a second convection separating plate connected to the first convection separating plate and retaining the reagent containers,
the fan is configured to cause air outside of the housing to:
flow into the first space through the first hole;
pass through the first space and the second space;
be brought into direct contact with the reagent containers, via a space defined by the first convection separating plate and the placement table and a space defined by the second convection separating plate and the placement table; and
flow out of the housing through the second hole.
