PROBLEM TO BE SOLVED: To increase the number of reagent storage chambers, without causing increase in the installation area. SOLUTION: Reagent racks 22b, 22c are supported individually rotatably around a common axis, and arranged in parallel along the axis. The reagent racks 22b, 22c are rotated individually by a rotation mechanism. Dispensation probes 28a, 28b absorb a reagent from reagent bottles 21 stored in the reagent racks 22b, 22c. A rectilinear moving mechanism moves the dispensation probes 28a, 28b, respectively to change each relative position relation in the axial direction between the reagent racks 22b, 22c and the dispensation probes 28a, 28b. Each of the reagent racks 22b, 22c holds a plurality of reagent chambers, can store the reagent and having an opening on the upper part respectively, while being arranged along a circle centered at the axis. The reagent rack 22b on the upper side includes a notched part 221, which is used as a passing path for the dispensation probes 28a, 28b. COPYRIGHT: (C)2010,JPO&INPIT
