Claims (1)

[Scope of Claim for Utility Model Registration] (1) A rice grain quality determination device comprising the following configuration. A: a light source that moves along the sample plate and irradiates light onto the rice grains on the sample plate; B: an optical system capable of condensing reflected light or transmitted light from the rice grains on the sample plate for each grain; C: the optical system. a photoelectric conversion unit that photoelectrically converts the light collected by the system and generates a signal corresponding to a predetermined spectral component; D a drive control unit that drives and controls a scanner unit that integrates the light source, optical system, and photoelectric conversion unit; , E A calculation control unit that A/D converts the signal from the photoelectric conversion unit into color data and determines the rice grain quality by calculating the color data and comparing it with the set value; F The set value and the value obtained by the calculation control unit A storage section for storing data, etc.; G. A display section capable of displaying at least the quality determination result output from the arithmetic and control section; H. A predetermined number of concave portions arranged in a predetermined number on the sample dish and shaped to follow the outer shape of rice grains. . (2) The rice grain quality determination device according to claim (1), comprising the following configuration. I. A first member that constitutes the sample dish and that is capable of covering at least the concave portion and a second member that can cover the sample fitted into the concave portion and the entire concave portion. . (3) The rice grain quality determination device according to claim (1), comprising the following configuration. J. An indication provided on or inside the sample dish that can be detected by the optical system. (4) The rice grain quality determination device according to claim (1), comprising the following configuration. K. A box body that houses the scanner section, the control section, the calculation section, and the display section, and has an insertion opening and a guide for inserting the sample dish at a position along the scanner section.
