BEAN SORTER

To solve such a conventional problem that it was required that abnormality such as color change and so on could be detected in the whole region on an external surface of an object to be sorted.SOLUTION: A bean sorter comprises: transfer means 14 which transfers an object h to be sorted so that the object passes through a measurement object region KT; illumination means 15 which illuminates the measurement object region KT; light reception means 16 which receives light reflected by the object h to be sorted positioned in the measurement object region KT; quality determination means which determines quality of the object h to be sorted; and separation means 18 which separates the object h to be sorted. The quality of the object h to be sorted is determined on the basis of light reception information of one side light reception means positioned at an upper side outer position and the other side light reception means 32 positioned at a lower side outer position.SELECTED DRAWING: Figure 3 【課題】被選別物の外表面における全領域を対象として変色等の異常を検出できるようにすることが要望されていた。【解決手段】計測対象領域ＫＴを通過するように被選別物ｈを移送する移送手段１４と、計測対象領域ＫＴを照明する照明手段１５と、計測対象領域ＫＴに位置する被選別物ｈにて反射した光を受光する受光手段１６と、被選別物ｈの良否を判別する良否判別手段と、被選別物ｈを振り分ける分離手段１８と、が備えられ、上方側外方位置に位置する一方側受光手段と、下方側外方位置に位置する他方側受光手段３２との受光情報に基づいて被選別物ｈの良否を判別する。【選択図】図３
