PURPOSE: To provide only the person desirous of having information with the information and to reduce the cost of an information acquiring means for obtaining such information by operating a voice generating section by a driving signal from a driving section when a software magnetic material passes a magnetic field region.
CONSTITUTION: A road side device 1 consists of an AC current generating section 2, a coil 3 for generating a magnetic field of a specified range by an AC signal, a driving section 7 which outputs a driving signal by a change in the magnetic field when the software magnetic material carried by a person enters the magnetic field region, a voice information section 9 which is operated by the driving signal from the driving section 7 and a voice generating section 11. The magnetic field is changed by the software magnetic material disposed within a stick when the sight handicapped person approaches a crossing or pedestrians' crossing, etc., and passes the magnetic field region. The driving section 7 outputs the driving section by such change in the magnetic field. The driving signal from the driving section 7 turns on the voice information section 9 and the information from the voice information section 9 is outputted as voices from the voice generating section 11. The person is thus able to obtain the desired information.
