PURPOSE:To provide a guiding tape for guiding an automated guided vehicle hardly influenced by diffused external light or the like for which guiding accuracy is not lowered even by dirt of the like. CONSTITUTION:An infrared ray emitting coating material whose main component is an infrared ray emitting phosphor is printed on one surface of a base material 2 by screen printing, gravure printing and offset printing, etc., for instance and an infrared ray emitting layer 3 is formed. Also, an adhesive material layer 4 is formed on a tape base material, it is covered with a peeling sheet 5 and this guiding tape 1 is stuck to a travelling surface such as a floor surface or the like by peeling off the peeling sheet 5. Then, the infrared ray emitting layer 3 is irradiated with infrared rays from the side of the automated guided vehicle and the infrared rays of a different wavelength are emitted from the infrared ray emitting layer 3 by excitation based on it. They are detected by a detector such as a photodiode or the like and the automated guided vehicle is guided based on the light emission signals. |
