CONSTITUTION:After the completion of an analysis, a specimen in a reacting container 11 is discharged by a suction nozzle, and then, the reacting container 11 is stopped in position A under a washing nozzle 15A, and cleaning operation is executed. And then, invisible dirt sticking to the inside wall surface of the reacting container is washed off by a squeezing member 23 is position B. And then, in position C, washing water is poured by a washing water nozzle 15B, and washing operation is conducted by sucking the water. Further, in position D, the inside surface of the reacting container is dried by a drying nozzle 24, and the washing operation is thus executed completely.
