Abstract:
Detection of contained metal contained in an article can be carried out with a high sensitivity with a simple operation in a limited space. A transmission coil  42  that generates a magnetic field for inspection from an upper surface side through a lower surface side of a placing table  21  and a plurality of magnetic sensors  43  for detecting the magnetic field are provided in a head  40  disposed on a lower surface side of the placing table  21  for placing an article which is an inspection object. When the head  40  is scanned so as to cover the entire lower surface-side region of the placing table  21 , metal being contained in the article placed on the placing table  21  is detected on the basis of a change in the magnetic field being detected by the magnetic sensors  43.

Claim (Index 1):
A metal detection apparatus for detecting foreign metal being contained in an article which is an inspection object, the metal detection apparatus comprising:\n a table for placing the article; magnetic field generation means for generating a magnetic field for inspection over an upper surface with a predetermined largeness of the table on which the article is placed from a lower region of the table which overlaps the upper surface; a magnetic sensor portion which is disposed in the lower region of the table and detects a near magnetic field with a sensing area narrower than the lower region; scanning means for moving a location of the magnetic sensor portion so that the sensing area of the magnetic sensor portion covers the entire lower region of the table; and determination means for determining presence or absence of the foreign metal being contained in the article placed on the table on the basis of a change in a magnetic field being detected by the magnetic sensor portion being moved by the scanning means.
