AUTOMATED ANALYZER

In an analyzer provided with a reagent container with a reagent lid in which there is a dispensing hole for dispensing a reagent, the upper space in a reagent container storage apparatus tends to easily warm up because of outside air flowing in through the dispensing hole. Furthermore, an automated analyzer having a mechanism to handle a reagent container or a mechanism to open and close a lid of the reagent container provided in a reagent container storage apparatus has a large number of motors which become a source of heat in the reagent container, and the upper space in the reagent container storage apparatus tends to easily warm up. Therefore it is desirable to equalize the temperature inside the reagent container storage apparatus. In view of the above problem, the present invention provides an automated analyzer provided with a reagent container storage apparatus that cools a reagent container, the reagent container storage apparatus being characterized in being provided with: a reagent storage chamber for storing the reagent container, the reagent storage chamber having at least one of the bottom surface and the side surface thereof cooled by a first cooling source; and a transfer member which is arranged to cover the reagent container stored in the reagent storage chamber, and which is thermally connected to the reagent storage chamber.
