2. Description of the Related Art In the fields of chemistry, medicine, analytical chemistry and the like, the development of fluorescence detectors and the like for measuring characteristics of fluorescent substances and the like has been progressing. When measuring a plurality of samples using a fluorescence detector or the like, as generally called batch processing,
After the measurement of one sample is completed, the reaction container, which is a sample measurement unit of the fluorescence detection device, is removed from the holder, and after cleaning, the reaction container is re-attached to the holder and prepared for the analysis of the next sample. Also,
For the purpose of accelerating the reaction between the sample and the reagent, a stirring member for uniformly mixing the sample and the reagent solution is provided inside the reaction vessel, and a driving mechanism for driving the stirring member is used for the reaction. It is provided outside the container. Further, since the fluorescence intensity varies due to a temperature change in summer or winter, constant temperature water or the like is circulated from a constant temperature water tank to the reaction vessel to keep the temperature constant. In addition, since the amount of a sample to be measured at one time is as small as several millimeters at most, and the reaction container is also small, the stirrer that can be mounted inside the reaction container must be small. It is not possible to use one with a simple structure. Therefore, a stirring member (magnetic stirrer) provided independently inside the reaction vessel and a magnetic drive device (magnetic stirrer) provided at the lower part of the reaction vessel and rotating the stirring member by magnetic force are used. The device is used. The configuration of the conventional sample mixing apparatus as described above is well known or obvious, and therefore is not shown.

When a measurement is performed using a conventional sample mixing apparatus, the reaction vessel must be removed from the holder for each measurement of a sample, and washing must be performed. Was virtually impossible to do.
In addition, since the reaction vessel itself is small, a strong (large) magnetic drive device having a strong magnetic force cannot be used, and the distance between the stirring member inside the reaction vessel and the magnetic drive device is longer than a predetermined distance due to an installation error or the like. When the length of the stirrer becomes longer, the strength of the magnetic field acting on the stirrer becomes weaker, and there is a possibility that the rotation of the stirrer may be defective. Furthermore, when the temperature is kept constant, since the constant temperature water is circulated from the constant temperature water tank to the hollow reaction vessel holder, the apparatus becomes large, the structure becomes complicated, and maintenance is required.
