The invention of claim 5, storing the sample or reagent is displayed identification information container
Or while moving the storage means in which the container is arranged sequentially photographed images of the container,
Before a first step of obtaining the images of Kiyo device, for the container arranged in said storage means, so that light impinges on the identification information, is irradiated toward the container, the contents a second step of obtaining the images of the vessel, and a third step of calculating a difference image obtained in the second step as the first step, the third
Based on the difference image obtained in the step, a fourth step of determining the presence or absence of sequences containers in the storage unit, with respect to the container to confirm the presence by said fourth step, the first step Gain in
A fifth step of the images read the identification information displayed on the container, a method for reading identification information attached to the container in the automatic analyzer, characterized in that it comprises a.

請求項１に記載の発明によれば、試薬庫の回転、停止を繰り返すことなく、容器に貼付

ことができるので、正確な分析結果を得ることにも寄与することができる。 According to the fifth aspect of the present invention, the identification information reading time can be shortened by reading the identification information affixed to the reagent container without repeating the rotation and stop of the reagent storage. Further, the liquid level of the reagent in the container can be largely shaken to prevent foaming and the reagent from jumping out. Therefore, since an accurate amount of reagent can be sucked with a probe and dispensed into a sample at the time of reagent dispensing, it can contribute to obtaining an accurate analysis result.
