Are provided so as to be spaced apart from each other, and are connected so as to send a detection signal from the thermal spray coating F to the conversion device 34 when the grounding portion 6c contacts the thermal spray coating F. The sensor 37 is a sensor for detecting the thermal spray coating F of the guide path 5 and the special display portion of the specific guide path 8, and the sensor 38 is a sensor for detecting information of the ground element S. The sensor 38 of the sensors 7 (movers) reads the stored information of the ground element S using radio waves by a frequency modulation method. In this embodiment, an example in which a plurality of sensors are used as described above is shown. However, in the case of using one sensor, the sprayed coating F gives signals of the same kind in the special display portion, for example, in the form of a bar code. This is possible if the sensor 37 is attached so that it can be detected. Also, a plurality of different kinds of signals set in the thermal spray coating F may be detected in one sensor 37.

Reference numeral 31a is a waterproof cover for covering the upper portion of the alarm button 31, and reference numeral 39 shown by a dotted line is a roller-type grounding tool, which can be provided by being replaced with the ring-shaped grounding portion 6c. For example, the user can walk with the cane 6 slidably contacting the sprayed coating F, and the sprayed coating F can be detected accurately, which is convenient.

When the cane 6 is used, the lid 6f is opened and the adjusting portion 34a is operated to set the detection signal pattern of the thermal spray coating F or the ground element S, or the sound of the speaker 32 is adjusted appropriately, and then the lid 6f is closed to grasp the grip portion. 6a is gripped and used for walking. User attaches cane 6 to sidewalk 1
When walking on the ground, if the ground portion 6c is brought into contact with the guideway 5 or the tip is directed downward, the walking stick 6 causes the sensors 37, (38) to be sprayed with the spray coating every time the ground portion 6c contacts the guideway 5. F is detected, and the detection signal is converted into an audio signal by the conversion device 34, and the speaker 32 informs the user of the existence of the sprayed coating F and the ground element S as an audio to make the information recognized. It should be noted that while the switch is ON, the notification may be made only when the pedestrian is out of the sprayed coating.

Therefore, if the user walks forward while listening to the sound, the user will not be separated from the guideway 5
Is a heat-resistant material W capable of discriminating and detecting the road surface derivative by the sensor 7 and sprayed and formed on the road surface as a road surface guiding film to easily perform the construction and to walk safely without a road surface with few irregularities. I am able to Further, when the vehicle reaches the specific guideway 8 along with the movement, the sensor 3
8 (or the sensor 37 itself) reads a pattern that causes a special reaction from the special display portion of the thermal spray coating F, and the detection signal is voiced from the speaker 32 via the conversion device 34, for example, close to the intersection or the pedestrian crossing 3. It is possible to inform the user of the fact that the road is the specific guideway 3a of the pedestrian crossing, the target building, and the road surface information such as the environmental information.

As a result, the user uses the tip of the cane 6 on the road surface 1a.
If the user simply walks so that the ground contact portion 6c abuts on the guide path 5 without tracing the user, it is possible to easily recognize the guide path 5 without error and walk safely. Therefore, even a user such as a blind person who is unfamiliar with walking can safely and easily walk with the cane 6 of this embodiment. Also, when it is necessary to call out to the surroundings when walking, it is convenient to press the alarm button 31 so that the speaker 32 can emit a sound at any time.
