Automatic analyzer

An automatic analyzer configured to dispense a sample and a reagent to each of a plurality of reaction containers to react the sample and the reagent, the automatic analyzer configured to measure a liquid that has reacted, the automatic analyzer comprising:

• a reagent disk configured to store a reagent bottle that has housed the reagent;
• a reagent mounting unit configured to be provided with the reagent bottle in loading the reagent bottle into the automatic analyzer;
• and
• a reagent conveying unit including a gripper unit that holds the reagent bottle and a reagent bottle lid opening unit that makes a hole in a lid of the reagent bottle, the reagent conveying unit configured to convey the reagent bottle that has been provided to the reagent mounting unit, into the reagent disk,
• wherein a gripper unit and reagent bottle lid opening unit drive unit is configured to coordinate and drive the gripper unit and the reagent bottle lid opening unit in the reagent conveying unit, so that when the reagent bottle opening unit moves in an upper or lower direction, the gripper unit simultaneously moves in the lower or upper direction reversely to the reagent bottle lid opening unit.
