Abstract: An automatic analyzer includes a sample dispensing unit that dispenses a sample into a reaction vessel, a reagent dispensing unit that dispenses a reagent, a sample nozzle cleaning tank that cleans a nozzle of the sample dispensing unit, a reagent nozzle cleaning tank that cleans a nozzle of the reagent dispensing unit, a compressor that supplies compressed air, and cleaning water supply means that supplies cleaning water. The tanks each have an upper vent that allows a nozzle to have access for cleaning, a lower vent that drains the cleaning water, a cleaning water jet port that sprays the cleaning water to the nozzle, and a compressed air jet port that removes residual cleaning water left on the nozzle. The lower vent has an opening area wider than that of the upper vent.
