PURPOSE:To attain the satisfactory unmanned services for a person inside a room, by stopping a truck after detecting that the truck arrives in front of the room door and knocking the door with a knocker provided to the truck to inform the arrival of the truck to the person inside the room. CONSTITUTION:A guide line 2 is buried into a floor 1, and a position bar 3 is buried at the position of a door 5 of a room. The traveling of an unmanned truck 6 is controlled by detecting the line 2 through a detector 8. In case the truck 6 is guided to a room number 5 of ''1234'', the truck 6 is driven after detecting the line 2. When the truck 6 arrives at the corresponding room, the bar 3 is detected by a position detector 9. Thus the truck 6 can stop accurately in front of the door 4. While the signal of the detector 9 drives a relay by prescribed times via a knocking command circuit, and a knocker 20 knocks the door 4. Thus the person inside the room can know the arrival of the truck 6. Then the person of the room takes goods out of a store box of the truck 6. |
