Claim 0:
1. An automatic analyzer comprising:
a housing unit which is capable of housing a plurality of rectangular parallelepiped reagent bottles, each reagent bottle having an integrated chip IC tag on one surface thereof;
an antenna which is used to communicate with the integrated chip IC tag;
a detector configured to detect the presence or absence of the reagent bottles; and
a control unit programmed to execute a reagent registration operation on a reagent bottle housed in the housing unit every time when the housing unit is opened and closed, wherein
the housing unit includes a housing container which is capable of being cooled by a cooling machine, a heat insulating material which covers a periphery of the housing container, a reagent tray which is provided with a plurality of reagent bottle holding portions holding the reagent bottles, a disk which rotatably holds the reagent tray, and a driving unit configured to drive the disk wherein the control unit is programmed such that in performing the reagent registration operation, when the detector detects a reagent bottle at a read position, the control unit performs a communication operation with the integrated chip IC tag of the reagent bottle installed in the reagent bottle holding portion located at the read position, and when no reagent bottle is detected, the control unit does not perform the communication operation, and
when the control unit is unable to communicate with the IC integrated chip tag of a first reagent bottle installed in the reagent bottle holding portion where the reagent bottles can be detected by the detector, the control unit determines that the first reagent bottle is installed in a reverse direction.
