PROBLEM TO BE SOLVED: To eliminate spatial waste in a reagent injecting device and manage with a single driving system of a reagent storage so as to attain miniaturization and cost reduction. SOLUTION: A reagent injecting device is provided with only one reagent storage 32 and two reagent probes 10, 12. In a reagent tray 33 of the reagent storage 32, reagent containers are arranged double on concentric circles from the rotational center. A reagent container row arranged in an outer position 36 has mutual clearances 37 within the row, and the circumferential reagent container positions are shifted between the inner and outer reagent container rows so that the display faces of the reagent containers arranged in an inner position 34 can be identified from the clearances 37. In one cycle, the reagent tray 33 repeats rotation and stop twice so as to perform dispensation in regular order by two reagent probes 10, 12. |
