Abstract
PURPOSE: To ensure an accurate reading of the marks, etc. written by the pencil featuring the regular reflection properties, by selecting the positional relation between the projector, receiver and slit so that the orthogonal projection onto the surface to be read may not be on the same line and then eliminating the effect of the regular reflection light caused by the mirror surface.
