PROBLEM TO BE SOLVED: To reduce stray radiation leaking out around a tablet. ;SOLUTION: A sample pan 20 is provided with a pit with a diameter a little larger than that of a sample tablet, and a tablet 24 is housed in the pit. On bottom surfaces 28 and 36 of the pit, a central hole with a diameter smaller than that of the tablet 24 is formed, and the tablet 24 is assigned between a light source 10 and a detector 22, and an annular shielding body 30 with a central hole which has the same diameter, substantially, as an exit hole of the bottom surfaces 28 and 36 of the pit, is assigned between the light source 10 and the tablet 24, the range of light beam with which the tablet 24 is irradiated from the light source 10 is converged.;COPYRIGHT: (C)1997,JPO
