ABSTRACT:
An inspection apparatus is provided to permit an inspector to easily inspect a face plate which has passed through a grinding process for flaws, an alien substance or an unground portion on the face plate surface. The apparatus includes a gate conveyor on which the face plate is conveyed. When the face plate is stopped on the gate conveyor, the sides of the face plate are engaged via padded piston rods and the gate conveyor swung open so as to permit the engaged face plate to be rotated for inspection purposes. Light sources may be positioned above and below the gate conveyor to aid in the inspection of a face plate.
