Automatic analyzer

An automatic analyzer comprising:

• a sample vessel transport mechanism for transporting sample vessels;
• a reagent vessel transport mechanism for transporting reagent vessels;
• a reaction vessel transport mechanism including a reaction bath and operative to transport reaction vessels;
• a sample dispensing mechanism for dispensing a sample in the reaction vessel;
• a reagent dispensing mechanism for dispensing a reagent in the reaction vessel;
• a display unit;
• an operation input portion;
• a memory;
• a plurality of analysis modules including the sample vessel transport mechanism, the reagent vessel transport mechanism, the reaction vessel transport mechanism, the sample dispensing mechanism, and the reagent dispensing mechanism;
• and
• an operation control unit that controls the operations of the plurality of analysis modules and the display unit, and that conduct an analysis of the sample placed in the reaction vessel,
• wherein the operation control unit stores, in the memory, an expiration date per maintenance item and execution time per maintenance item of the analysis module, displays, at the display unit, the execution time along with identification representation of execution priority based on the expiration date, displays, at the display unit, the individual maintenance items of each of the plurality of analysis modules with marks permitting the operator to identify whether or not a maintenance item in question can be executed, rearranges the display order of the maintenance items based on the execution priority according to an operator's instruction inputted via the operation input portion, and displays the rearranged maintenance items at the display unit.
