no. 1 approach
[0077] figure 1 It is a block diagram showing the functional configuration of the automatic analyzer 1 of the first embodiment. The automatic analyzer 1 measures indexes related to the reaction between a sample inserted into a reaction tube and a reagent, and calculates physical property values of the sample based on the measured indexes.
[0078] The automatic analysis device 1 includes an analysis mechanism 2 , an analysis circuit 3 , a drive mechanism 4 , an input interface 5 , an output interface 6 , a communication interface 7 , a storage circuit 8 , a control circuit 9 and an adjustment mechanism 16 .
[0079]The analysis mechanism 2 supports a reaction tube for holding a mixed solution of a sample and a reagent, and measures an index related to the mixed solution in the reaction tube. Hereinafter, an example of using the test tube 70 as a reaction tube will be described. The index related to the liquid mixture is, for example, the physical property value of the samp...
no. 2 approach
[0177] A second embodiment will be described. This embodiment modifies the configuration of the first embodiment as follows. In the present embodiment, the gain of the light receiving unit 62 is adjusted using the light emitting unit 163 for adjustment provided instead of the light receiving unit 162 for adjustment. Description of the same configuration, operation, and effect as those of the first embodiment will be omitted.
[0178] The control circuit 9 uses the adjustment function 92 to adjust the gains of the plurality of light receiving units 62 . The control circuit 9 that realizes the adjustment function 92 is an example of an adjustment unit.
[0179] Figure 11 It is a figure which shows an example of the structure of the adjustment mechanism 16. FIG. Figure 11 It shows a cross section substantially parallel to the rotation axis R of the reaction disk 201 and substantially parallel to the radial direction centered on the rotation axis R. The adjustment mechanism...
no. 3 approach
[0213] A third embodiment will be described. This embodiment modifies the configuration of the first embodiment as follows. In this embodiment, instead of using an adjustment mechanism including an adjustment light receiving unit and an adjustment test tube that guides the light emitted from the light emitting unit 61 to the adjustment light receiving unit, an adjustment test tube 80 incorporating an adjustment light receiving unit 88 is used. . Description of the same configuration, operation, and effect as those of the first embodiment will be omitted.
[0214] Figure 14 It is a figure which shows an example of the structure of the test tube 80 for adjustment of this embodiment. Figure 14 One of the adjustment test tubes 80 disposed in each of the grooves 2011 is shown as a cross section substantially parallel to the rotation axis R of the reaction disk 201 and substantially parallel to a radial direction centered on the rotation axis R.
[0215] The test tube 80 for a...
