Abstract

PURPOSE: To detect a knifed mark automatically by obliquely applying a light ray to the surface of a plate to be checked through a cylindrical lens and by measuring the reflected ray received through another cylindrical lens.
CONSTITUTION: The light ray from a light source 1 such as a straight type halogen lamp is made a belt-shaped parallel ray through the cylindrical lens 2 and is obliquely applied to the surface of a sliced venner 7 to be checked. When the knifed mark 8 is present on the surface of the sliced venner 7, a stronger reflected ray is emitted upwards and applied to a screen 6 through a cylindrical lens 3, and the reflected ray through a slit 4 is photoelectrically converted to detect the knifed mark 8. Since the direction of the knifed mark is determined by the direction of the edge, the knifed mark and the cylindrical lens 2 are previously made parallel to each other. In this way, the knifed mark can automatically be detected.
