Claim 3:
4. An automated analyzer comprising:
a probe configured to dispense an object into a plurality of reaction vessels for reacting a sample with a reagent;
a measurement unit configured to measure a reaction liquid mixture of the sample and the reagent in the reaction vessel;
a cleaning tank configured to clean the probe; and
a control device configured to control an operation of the probe, an operation of the measurement unit, and an operation of the cleaning tank, wherein the cleaning tank includes:
a cleaning pool configured to store an amount of cleaning water for immersing and cleaning the probe by inserting the probe from above;
a supply valve configured to supply cleaning water from a pump to the cleaning pool by switching between a shut off state where a first supply of cleaning water to the cleaning pool is shut off by the supply valve to a flow state where the first supply of cleaning water is supplied to the cleaning pool by the supply valve;
a drying tank provided apart from a side of the cleaning pool and configured to suction cleaning water adhering to a surface of the probe in a tip end direction of the probe by inserting the probe from above; and wherein
the control device is configured to
insert the probe into the cleaning pool, to immerse the probe and to clean the probe in the first supply of cleaning water in the shut off state,
to pull the probe out of the cleaning pool after immersing and cleaning the probe in the first supply of cleaning water, and
to move the probe and to insert the probe into the drying tank after pulling the probe out of the cleaning pool, and to suction cleaning water on the surface of the probe,

wherein in the cleaning pool of the cleaning tank, a pump for supplying cleaning water is configured to supply cleaning water from a position lower than a liquid level of cleaning water stored in the cleaning pool.
