PURPOSE:To enable disposition of specimens without receiving positional limitations by providing a driving mechanism which rotates a sampler by one turn plus one pitch at every one cycle. CONSTITUTION:Plural pieces of the specimens S1, S2,-Sn are imposed on the sampler 1 and an ID reader 2 and a sampling mechanism 3 are disposed to the desired positions around the sampler 1. The driving mechanism 4 is constituted of a pulse motor, etc., and drives the sampler 1 so as to rotate the same by one turn plus one pitch at every one cycle. Since all the specimens pass the ID reader at every one cycle, the IDs are read without fail. Sampling is, therefore, possible even if the specimens are disposed in any positions. Namely, the disposition of the ID reader 2 in any position is possible; in an extreme case, said reader can be disposed to the position one pitch before the sampling mechanism 3 and, therefore, the exchanging, adding, sampling, etc., of the specimens in any positions are enabled during the process of treatments; interruption is possible of course.
