Abstract

PURPOSE:To increase the data transmission quantity by scanning an optical beam so as to follow driven vehicles arranged on a road or selecting a photodetector having the largest photodetection output of plural photodetectors arranged to the vehicle. CONSTITUTION:When a vehicle 14 approaches a vehicle sensor 20 and a vehicle sensing section 26 senses the approach, a vehicle sensing signal is generated. The signal is inputted to a control section 38 of a photodetector 18. On the other hand, a speed detection section 22 and a distance detection section 24 are operated by the signal and the detection data is inputted to a control section 38. The control section 35 calculates the angular velocity of a rotating body 44 and a timing of the vehicle 14 reaching the start point of the section A depending on the vehicle velocity and the distance data and the beam scanning section 34 drives the rotating body 44. Simultaneously, a light emitting element drive section 32 modulates the light emitting element 30 by voice information or the like and the modulated radiation beam is generated. The rotating body 44 is driven aud the radiated optical bream is scanned from the beam 56a to 56d directed to the location of the section A in matching with the drive of the vehicle 14 to send lots of data.
