<p>PURPOSE:To enable raw unhulled rice grains to be subjected to spectral analysis by cutting upper and lower edge portions of unhulled rice grain which is retained by a placement portion with a blade which moves horizontally and then emitting a flux of rays for measurement. CONSTITUTION:Upper and lower edges of a sample S which is separated and placed for each placement portion 9 are cut by traveling in horizontal direction along the placement portion 9 of upper and lower pair of blades 10C and 11C. The upper and lower cutting pieces are eliminated from the placement portion 9 by traveling in horizontal direction along the placement portion 9 of exclusion portions 10D and 11D as in the blade 10C, 10C and the sample S whose upper and lower edges are cut remains on the placement portion 9. A flux of light for measurement is emitted from a light-projecting portion 2 at the upper portion of the placement portion 9. The flux of light passing through the sample S is received by light-reception portion 3 which are provided separately at a bottom portion of the placement portion 9, thus enabling constituent analysis to be made immediately.</p> |
