Abstract: The object of the invention is to avoid a decrease in dispensing accuracy of a sample, a reagent, or the like as a temperature changes. In an automatic analyzer, a dispensing nozzle sucks the sample from a sample container holding the sample and discharges the sample to a reaction container. A syringe pump controls an amount of change in a volume of water. A first pipe connects the dispensing nozzle and the syringe pump. An electromagnetic valve flows or stops the water. A second pipe connects the electromagnetic valve and the syringe pump. A branch pipe branches the water. A third pipe connects the electromagnetic valve and the branch pipe. A case accommodates at least the syringe pump, the first pipe, the electromagnetic valve, the second pipe, the branch pipe, and the third pipe. Further, the third pipe includes a heat exchange unit that performs heat exchange of the water.

Abstract: To provide a technique that is related to a cleaning mechanism of an automatic analyzer and which is adapted to reduce variability of a cleaning range in a reaction vessel so that blank value measurement and the like are less affected by the variability of the cleaning range. The automatic analyzer controls a sequence including optical measurement and cleaning and includes a discharge mechanism including a discharge nozzle for discharging a liquid into a reaction vessel; and an overflow suction mechanism including an overflow suction nozzle for sucking an overflow amount of the liquid in the reaction vessel. In a liquid discharge step included in a cleaning process and interposed between a preceding step using a detergent and a succeeding blank value measurement step, the automatic analyzer establishes a first state where a lower end of the discharge nozzle is located at a first position in a heightwise lower part of the reaction vessel and a lower end of the overflow suction nozzle is located at a second position in an upper part of the reaction vessel, and provides control so as to carry out the discharge of liquid from the discharge nozzle and the suction of the overflow amount of liquid through the overflow suction nozzle.

Abstract: In the prior art, in transport lines equipped with multiple stages of transport lines driven in different directions, it was necessary that drive power sources for driving the belts of the transport lines be provided in a number equal to the number of transport lines. This led to an increased number of drive power sources and to an unavoidable increase in the power consumed by the device as a whole. In the present invention, there is adopted a mechanism for the parallel driving of a plurality of transport lines by a single drive power source, whereby the number of drive power sources needed to drive the transport lines can be reduced, as can the power consumed by the system.

Abstract: Provided is a technique related to an automatic analyzer and capable of ensuring cleaning performance of a reaction container by a cleaning process including a tip suction step, and preventing decrease in analysis accuracy or improving the analysis accuracy. The automatic analyzer includes a control apparatus, a block suction mechanism that moves a suction nozzle and a suction block for suctioning a liquid in the reaction container up and down and suctions the liquid, and a block cleaning mechanism for cleaning the suction block. After receiving an analysis request, the control apparatus causes, in a tip suction step that is provided before an analysis step and is a last step of a cleaning step, both suction of the liquid by the block suction mechanism and cleaning of the suction block by the block cleaning mechanism to be performed in a first step, and then only the suction of the liquid by the block suction mechanism to be performed in a second step including one or more cycles; and causes the analysis step to be performed using the reaction container in which the second step is performed.
