PURPOSE:To return a sample container, of which analysis work is completed, to any vacant position of a turn table after picking a desired sample container from multiple sample containers placed on the turn table and performing the analysis work, and place a new sample container in the case that a temporary vacant position exists because of the during the analysis work, and reduce the radiation exposure in the analysis work of sample including the radiation material. CONSTITUTION:Multiple pan housing holes 17a are provided in a turn table supported by a fixed base 11 freely to turn, and sample containers 7 housed in the pans 14 made of the shielding material are place in these pan housing holes 17a. An identification mark 23 formed with multiple concentric channels is provided in the lower surface of the pan 14, and a sensor 15 for optically detecting the discrimination mark 23 at an automatic delivery position 12a and a sensor 16 for optically detecting the existence of the sample container 17 in the pan 14 are provided in the fixed base 11.
