Abstract
PURPOSE:To greatly improve detection accuracy in comparison with the case of visual observation by detecting the difference in the detection time of the reference light from a reference light source and reflected light which are respectively projected to a photodetector by a slit and detecting the deviation between the collimated beams of light and the reflected light. CONSTITUTION:The degrees of the deviation of the focal point C on a photosensor 20 from the reference point A and point B in a Y-axis direction and X-axis direction are detected in a control circuit 54 if a mirror 18 deviates from the optical axis of a convex lens 14 with an inclination by theta deg.. A light emitting diode 72 or 82 is not lighted if the deviation exceeds a previously stored set value. Whether the deviation of the optical axis of the mirror 18 is permissible or not is, therefore, detected automatically. The detection accuracy is thereby greatly improved in comparison with the conventional case in which the deviation of the optical axis is detected visually.
