Zusammenfassung: | PURPOSE:To exactly detect the unit advance quantity, the azimuth to a running path or the present position to the left and right directions of the running path by providing the running path having a light projecting means installed at a predetermined distance and an angle. CONSTITUTION:Light beams projected from a pair of light projecting means 3, 3' are received by a pair of light receiving means 5 successively in accordance with the advance of a moving body 2. As the moving body 2 advances, a pulse generating means 8 loaded on the moving body 2 stores temporarily measured pulse information in a memory 11. Also, based on a distance of pair of light projecting means 3 installed at a prescribed interval from a constant ROM 10 in which a constant is stored in advance, an angle of the light projecting means 3' for projecting a light beam at a prescribed angle, and the distance between the light receiv ing means 5 loaded on the moving body, an operation 12 is executed by the number of pulses measured by the pulse generating means 8 being proportional to the advanced quantity and a light receiving timing of light beams from each light projecting means 3, 3', and the unit advanced quantity on the running path, or the position and the azimuth to the running path are outputted 13. |
