<p>Provided is a position detecting system using light, whereby configuration of a subject to be measured can be simplified. In a position detecting system (100), forklifts (20) are respectively provided with light source units (21) (light source units (A-E)) that radiate light having a wavelength (lambda). Fixed light receiving units (30) (I-XII) detect the light having the wavelength (lambda), and transmit signals by combining identification signals (S1) for identifying the light receiving units, and light receiving information (S2) that includes light quantity signals. The position calculating unit (64) calculates the positions of the light source units (21) on the basis of the identification signals (S1) and the light receiving information (S2).</p> |
