To detect a line position described on a surface by a simple structure, the line position detecting apparatus comprises a light beam generator including a laser diode, a collimator, a prism, and a mirror; a motor for rotating a laser beam to describe a circular locus on the surface; an encoder for detecting a laser beam angular position; a photosensor for detecting a laser beam reflected from the surface; and a calculator for detecting an angular position at which light beam intensity changes due to the presence of the line at at least one point of intersection between the line and the circular locus and for calculating the point indicated by x-y coordinates on the basis of the diameter of the circular locus and the detected angular position of a line to be detected.
