PURPOSE:To apply required communication to a truck traveling on a passage. CONSTITUTION:This equipment is provided with a truck 3 traveling on a passage 2, infrared transmitters 6 provided opposed to the truck passage 2, and two opposite reflection boards 4 and 5 provided along this passage at least. Then, infrared rays added control information are projected from the infrared transmitters 6, and a required distance is irradiated while repeatedly reflecting the projected infrared rays with the opposite reflection boards 4 and 5. On the other hand, the truck 3 is provided with an infrared receiver 8. Therefore, a required command is applied to the truck 3 by the infrared transmitters 6. Thus, the infrared rays with added signals are projected to the truck at any position on the passage so as to enable communication. |
