Automatic analyzer and sample storage device

An automatic analyzer comprising:

• an analyzation unit;
• a transportation line, including a belt and a motor driving the belt, that executes carrying-in/out of a rack, among a plurality of racks, in which a sample is mounted from/to the analyzation unit;
• a cold storage that cools the plurality of the racks in which the sample having been measured in the analyzation unit is mounted;
• a control unit configured to execute operation control for carrying-in of the rack from the transportation line to the cold storage and operation control for carrying-out of the rack from the cold storage to the transportation line;
• a front chamber that is disposed between the cold storage and the transportation line, an inner space of the front chamber being shielded from the outside, and the front chamber having a first entry/exit and a second entry/exit;
• and
• a temperature control unit that controls a temperature of the inside of the front chamber to a temperature between that of the outside of the cold storage and that of the inside of the cold storage,
• wherein the transportation line is adjacent to only one of the first entry/exit and the second entry/exit of the front chamber, and
• wherein the automatic analyzer further comprises:
• a partition plate formed a deformable material disposed between the front chamber and the cold storage which shields an inside space between the front chamber and the cold storage from outside of the inside space to keep the inside space a same temperature as the cold storage.
