PURPOSE:To make grouping control easy by using >=2 kinds of sample racks, using a different sample rack for each different specimen group, and providing a read means capable of identifying the first rack to each group. CONSTITUTION:A sample rack 1, for example, is colored yellow and magnets 2, 2' and 2'' are provided below the first holes 3-1, 3-2 and 3-3 for holding sample test tubes 4 among the holes 3-1, 3-2-3-n. Thus seven different kinds of samples can be shown with the combination of number and position of the magnets. Another sample rack 10 is colored white, and the combination of color and position is made in the same way. In this way, a sample of the same group is charged into the test tubes 4 in the holding holes of each rock from a dispenser 11 until the color of the rack and the combination of magnets are changed. A magnetic sensor or lead switches 8, 8' and 8'' are provided to a belt 6 for carrying the racks 1 and 10 to the dispenser 11 in order to enable the identification. Thus the control of the specimen groups in a multi-item automatic analytical apparatus can be simplified. |
