To provide an automated analyzer capable of shortening analysis time. The automated analyzer includes a vessel which contains a mixed solution of a specimen and a reagent; and a control unit which controls a first operation performed on the vessel, a second operation performed on the vessel after the first operation, and a third operation performed on a predetermined mechanism of the automated analyzer before the second operation, in which the control unit performs the first operation and the third operation in parallel. Alternatively, the automated analyzer includes a control unit which controls a first operation performed on the vessel, a second operation performed on the vessel after the first operation, and a third operation performed on a predetermined mechanism of the automated analyzer after the first operation, in which the control unit performs the second operation and the third operation in parallel.

An automatic analysis apparatus is capable of stirring a reagent without reducing the analysis processing capacity. The automatic analysis apparatus includes a reagent table that is rotatable and that holds reagent vessels, and a plurality of magnets are disposed below the reagent table, with orientations of magnetic poles of the magnets fixed, along a movement path of the reagent vessels moving on a circumference when the reagent table is rotationally driven. The plurality of magnets is disposed such that the fixed orientations of the magnetic poles of the magnets vary along the movement path, and act a magnetic force on a stirring bar in each of the reagent vessels. When the reagent table is rotated and the reagent vessels pass above the magnets, the stirring bar in each of the reagent vessels is rotated or oscillated by the magnetic force received from the magnets, to stir the reagent.

Provided is an automatic analyzer capable of further reducing carryover between specimens. The automatic analyzer includes a first dispensing unit for dispensing a specimen related to a first analysis item group having a high possibility of carryover, a second dispensing unit for dispensing a specimen related to a second analysis item group having a low possibility of carryover, an input unit for receiving an input of analysis information related to a plurality of analysis items for a specimen, a classification unit for classifying the analysis information into the first analysis item group and the second analysis item group, and a determination unit for determining a dispensing sequence for each specimen for the first analysis item group and determining a dispensing sequence for each analysis item for the second analysis item group.

A pretreatment device for performing pretreatment using a liquid sucked by a probe from an inside of a septum-attached container includes: a container holding unit which has a space for accommodating the septum-attached container and is provided with a hole into which the probe is inserted with respect to a septum of the septum-attached container to be stored; an installation unit in which the container holding unit is detachably installed; and a fixing unit which fixes the container holding unit to the installation unit in a state where the container holding unit is detachably installed in the installation unit, to solve the above-described problem.

A biological material measuring instrument is described. The biological material measuring instrument includes a rotating body and a main body. The rotating body includes one or more cartridge holders having cuvettes in which a reagent and an analyte in a sample react. The main body includes a pair of light-emitting parts and light-receiving parts to optically measure the analyte in the sample. The rotating body further includes a light-emitting optical waveguide for guiding the light of the light-emitting parts to the cuvette, and a light-receiving optical waveguide for guiding.
