A board turning apparatus is provided with a conveyor for transporting a board through an inspection station; the inspection station includes an array of photocells located below the conveyor and which operate to detect and scan the facing surface of a board as it passes over the photocell or is held in the inspection station by a detent arm; the output of the scan by the photocell array is delivered to a computer having an analyzing program for detecting discoloration in the surface or edges of the board that are scanned by comparing the scan to a set of conditions stored in the computer; a turning arm is connected to the computer and is actuated to engage an edge of the board and turn the board over by rotating it about its opposite edge on the conveyor to turn over the board to facilitate and optimize subsequent operations on the board such as edging of the board.
