DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cereal grain observation apparatus, and more particularly to a cereal grain observation apparatus which transmits light to cereal grains such as rice grains to detect a torso crack or the like from a dark shadow seen in the cereal grains. About.

[0002]

2. Description of the Related Art Cracking of cereal grains such as rice grains is a factor of deteriorating the quality of cereals, and it is required to find and eliminate cracked cereal grains. For this reason, conventionally, a method has been adopted in which cereal grains are arranged in a large number of through-holes to transmit light, and the presence or absence of dark shadows in the cereal grains is examined to find cereal grains having a broken body.

[0003]

However, in the case of the above-described conventional example, since the transmitted light of the cereal grains is observed, for example, cereal grains which do not transmit light, such as rice and beans. Could not be observed. Therefore, the present invention is not only capable of observing rice grains such as brown rice and polished rice, but also observable of grains that do not transmit light such as rice, beans, etc., and can determine the quality of the grains, and can easily be used outdoors. It is an object of the present invention to provide a grain observation device.

[0004]

According to a first aspect of the present invention, there is provided a cereal grain observation apparatus comprising: a sample dish having a transparent bottom plate on which cereal grains are placed; and a transparent window on which the sample dish is placed.

And a lid provided with an upper illumination means for irradiating. According to this invention, the cereal grains on the sample dish are provided with lower illuminating means for irradiating lower illuminating light for transmission, and upper illuminating means for irradiating upper illuminating light for reflection on the cereal grains. Therefore, it is possible to perform both observation of transmitted light from rice grains and the like using lower illumination means and observation of transmitted light from rice grains and the like using upper illumination means. It is also possible to observe cereal grains that do not transmit light, such as beans, and determine the quality of the grains. The cereal grain observation device according to the invention according to claim 2, a sample dish provided with a transparent bottom plate on which cereal grains are placed, and an apparatus main body provided with a transparent window on which the sample dish is placed at an upper portion,
