Automatic analyzer and probe washing method

An automatic analyzer comprising:

• a dispensing mechanism which is equipped with a probe which performs liquid aspiration and discharge;
• a syringe pump which is connected to the probe and performs the liquid aspiration and discharge;
• a feed pump which feeds washing water for washing the inside of the probe to the probe via the syringe pump;
• a detergent storage part which stores a detergent which washes the probe;
• a washing tank which is adapted to wash the probe;
• and
• a controller which controls the dispensing mechanism and the syringe pump, wherein
• the controller,
• in a case of washing the probe by sucking the detergent by the probe a plurality of times, controls the syringe pump so as to discharge the detergent in the washing tank after sucking the detergent in the detergent storage part and to suck the next detergent in the detergent storage tank without feeding the washing water to the probe by the feed pump.
