ABSTRACT:
An opaque foreign article sorting apparatus which can sort an opaque foreign article during dropping from a conveyor precisely with a high degree of accuracy. Objects including transparent bodies in which opaque foreign articles may mix are scanned, during dropping, horizontally linearly with a laser beam, and reflected light is detected by a CCD image sensor. Whether an object scanned is a transparent body or an opaque foreign article is judged at each CCD block including N CCDs, and when an opaque foreign article is judged at a CCD block, air is jetted from a corresponding nozzle block and adjacent nozzle blocks to blow off the object.
