Abstract: Provided is an automatic analyzer capable of simplifying control of a holding unit that holds a plurality of containers having access to an aspiration nozzle whose position is fixed and that rotates and moves up and down. The automatic analyzer includes an aspiration nozzle whose position is fixed and that aspirates reaction liquid or reagent, and a holding unit that holds a plurality of containers accommodating the reaction liquid or the reagent, and that rotates and moves t up and down. The holding unit holds at least three of the containers, and an angle between adjacent containers is an integer multiple of a predetermined angle. The angle between adjacent containers is an angle between adjacent containers in a circumferential direction and an angle around a rotation center of the holding unit.

Abstract: An automatic analyzer comprises a reagent storage unit, a reaction promotion unit, and an unused container providing unit. The reaction promotion unit is between the reagent storage unit and the unused container providing unit in a left-right direction, and is on a rear side from the reagent storage unit and the unused container providing unit in a front-rear direction. In the automatic analyzer, a cover covering the reaction promotion unit is with a first fitting portion, a second fitting portion, and a third fitting portion located between the first and the second fitting portion in the left-right direction and a handle that is between the first and the second fitting portion in the left-right direction and on a rear side of the third fitting portion in the front-rear direction. The first and the second fitting portion are high in positioning functionality. The third fitting portion is low in positioning functionality.
