Although the input and output signal levels of the induction coil 3 are the same and the output of the comparison unit 6 maintains, for example, an “H” level state, an object that is electromagnetically coupled to the induction coil 3 is generated and When the inductance greatly changes, a level difference occurs between the input and output signal levels of the induction coil 3, and the output of the comparison unit 6 is inverted to, for example, the “L” level. Sound generating device 7 as an output device controlled by the output of comparing section 6
When the output of the comparison unit 6 is inverted to the "L" level, the speaker 8 is driven to generate a prescribed voice message.

The frequency of the AC magnetic field C is set to 50 kHz so that the inductance of the induction coil 3 changes largely due to the proximity of the insole 2 to the induction coil 3 and the loss is not so large. ~ 120K
Hz is preferable, and in experiments, 80 KH
The operation was confirmed with an alternating magnetic field C of about z.

With this configuration, the user E who puts the insole 2 in which the material having high magnetic permeability is used in the footwear 1 is used.
When approaching the danger area B, the insole 2 is electromagnetically coupled to the induction coil 3 and the inductance of the induction coil 3 changes greatly. Is generated and the user can be made to recognize that he is approaching the dangerous place.
Therefore, the user E simply carries the insole 2 made of a material having a high magnetic permeability in the footwear 1 and does not need to carry a device in which the electronic circuit is incorporated. A reliable guidance operation can be expected.

The user guidance system shown in FIG. 2 automatically informs the management center when the user E approaches a dangerous place. The user can use the same insole 2 as in the embodiment shown in FIG. Is carried in the footwear 1. Those having the same functions as those in FIG. 1 are denoted by the same reference numerals. When the comparing unit 6 detects the approach of the user, the notifying device 9 as an output device whose operation is controlled by the comparing unit 6 notifies the management center 11 of the individual code of the dangerous place B via the line 10. The management center 11 which has received the report determines the pertinent danger area B from the received individual code, and, for example, dispatches a staff member to the danger area B promptly to guide the user E to a safe area. To process. As described above, the same effects as those of the embodiment of FIG. 1 can be expected in the embodiment shown in FIG.

The security of the user E is ensured by preventing the user E from accidentally entering the dangerous place B. Therefore, the user E simply carries the insole 2 made of a material having a high magnetic permeability in the footwear 1 and does not need to carry a device in which the electronic circuit is incorporated. A reliable protection operation can be expected.

In the user protection system shown in FIG. 3, the automatic door 12 driven by the opening / closing device 14 is described as an example.

Specific examples of the range of use by healthy persons include voice messages of exhibits in museums and exhibitions, and guidance on displays such as CRT displays.

As described above, according to the user guidance system of the present invention, the sensor carried by the user is made of an amorphous alloy having a high permeability of about 50,000 at a frequency of 10 KHz, and an induction coil. The proximity of the sensor is detected from the occurrence of a change in the inductance of the sensor, and the output device gives a guidance instruction to the user, so that an expensive device incorporating an electronic circuit as in the related art is provided to the user. It is not necessary to carry it, and even if a general metal object with low magnetic permeability is close to the above-mentioned sensor,
This can prevent occurrence of a situation in which a guidance instruction is erroneously given to the above-mentioned sensor, and differentiate the user from the above-mentioned sensor by distinguishing the above-mentioned sensor from a general metal object having low magnetic permeability. Thus, it is possible to reliably give the guidance instruction only to the user.
