Abstract

In order to make it possible to image the surface of a workpiece from a plurality of directions without reducing the amount of light to be projected to the workpiece, a light projection device having light emitting surfaces opposite to the workpiece and formed with a slit allowing light reflected by the workpiece to pass from the light emitting surface side toward an opposite side thereof is adapted such that the slit is formed in a tapered shape whose width gradually increases from the light emitting surface side toward the opposite side.
