摘要: Apparatus and method for detecting removing foreign substances 2' mixed with manufactured articles 2 by comparing the infrared rays reflected each product 2,2' a predetermined reference value to identify actuating an ejection mechanism 10 remove based upon comparison result. In embodiment illustrated, filter 6 passing only radiation is interposed in path of light. Alternatively, (Fig. 2), such may be incident further modification, wanted instead substance separated from stream. A plurality assemblies positioned around observation station.
