Abstract: An automatic analysis device improves the uniformity of a mixed liquid by noise agitation by a dispensing mechanism. The dispensing mechanism agitates a mixed liquid by suctioning the mixed liquid into a reaction vessel by a nozzle and then re-discharging the suctioned mixed liquid into the reaction vessel. When the mixed liquid is re-discharged into the reaction vessel, the nozzle is moved upward at a speed higher than a speed at which the liquid surface of the mixed liquid rises due to the re-discharging of the mixed liquid from the nozzle during a first period and lowers the speed of moving the nozzle upward than the speed during the first period while maintaining or reducing the speed at which the liquid surface of the mixed liquid rises due to re-discharging of the mixed liquid from the nozzle during a second period following the first period.

When it is determined that the activation determination operation unit 15B has properly performed the activation determination, the control of the controlled object 16 based on the activation determination is permitted. When it is determined that the activation determination operation unit 15B has not properly performed the activation determination, the control of the controlled object 16 based on the activation determination is not permitted.

Abstract: In the past, when centering the center of a liquid surface and fixation thereof proved difficult during mounting a container into an automatic analytical apparatus, there was sometimes the possibility that the accuracy of checking the liquid surface conditions and the pipetting precision could not be ensured. When this problem occurred, there was the possibility that the reliability of the analysis results would be diminished. Accordingly, an automatic analytical apparatus is provided with a probe for suctioning a liquid to be used in analysis, wherein the apparatus is provided with a transport apparatus for transporting a container accommodating the liquid, and a container-clamping apparatus for clamping the container transported by the transport apparatus. The container-clamping apparatus has a vibration suppression mechanism for retaining the clamped container with an elastic body, and a centering retention mechanism with which centering of the container center can be fixed.
