PURPOSE:To obtain a position detecting apparatus simple in constitution and receiving no regulation of the Wireless Telegraphy Act, by detecting the position of a moving object by receiving the reflected beams from three known places of laser beam generated from the laser beam means of the moving object. CONSTITUTION:The laser beam from the semiconductive laser 10 mounted to a moving body is emitted to the reflection means at three known points through the slit 6 of a rotor 3 and the reflected beams are scanned to the rotary direction by the rotor 3 to be received by the light receiving elements 6, 7 of the rotor 3. Whereby, registers are successively selected through a ring counter and reflected beam detecting angle directions are stored by a rotary encoder 9. CPU calculates the open angles between three known points on the basis of these stored valves and the position of the moving object is determined by these calculated values and the positional informations of three known points. By this beam utilizing system, the position detecting apparatus of the moving object receiving no regulaton of the Wireless Telegraphy Act is obtained in simple constitution. |
