Description

  The present invention relates to an automatic analyzer for qualitative and quantitative analysis of biological samples such as blood and urine.

  Automatic analyzers that perform qualitative and quantitative analysis of biological samples such as blood and urine are required to perform analysis of multiple items in multiple samples in a shorter time, and perform analysis processing in parallel using multiple analyzers. Analysis time is shortened by adopting a module assembly method. In addition, some maintenance is manually performed by an operator, but from the viewpoint of reducing the time of the entire analysis process, the maintenance time is similarly required to be reduced.

  In manual maintenance by an operator or the like, it is necessary for the operator himself to check various information about the analysis processing in the automatic analyzer, and to perform maintenance based on the information. It becomes very complicated.

  As a conventional technique for confirming such information, for example, Patent Document 1 discloses the same arrangement as the actual physical arrangement of at least one of a sample rack on which a sample container is installed and a reagent disk on which a reagent container is installed. A technique is disclosed in which a state is displayed on a display device provided in a control device, a type of a specimen or reagent classified in advance is designated, and the designated specimen or reagent is distinguished from other things and displayed.
