Provided is an automatic analyzing device including a sample container 2 for accommodating a sample 1 to be assayed, a dispensing probe 5 for dispensing the sample 1, and an electroconductive tip 11 removably mounted on a portion of the dispensing probe 5, the portion being to be dipped in the sample 1; wherein this analyzing device detects capacitance between the tip 11 of the dispensing probe 5 and a region having a ground potential 9 predefined as a reference electric potential in the analyzing device, and on the basis of a result of the detection, determines a mounted state of the tip 11 on the dispensing probe 5. A fall of the tip from the probe is thus immediately detected. |
