Moreover, a table 14 is advanced and the test piece is made to drop thereon. With the advance of the table 14, it comes into contact with a sensor case 15 and a back box is formed of the two. A prescribed urine inspection analysis is executed by a light-emitting element 15a and a photodetector 15b provided in the case 15. After completion of the analysis, the table 14 is moved backward with the test piece held by the slider 21. According to this constitution, it is made easy to attain precision in positioning when the black box is formed, and a structure can be made simple.
