  FIG. 6 is a schematic explanatory diagram of the guide sign 1 of the present example. As shown in this figure, the guide sign 1 can be generated by the solar cell 4 when the solar cell 4 is exposed to light. The electric power thus obtained is direct-current power, and can be supplied to the storage battery 7. Further, the guide sign 1 can be generated by the generator 6 when the vertical axis wind turbine 5 rotates by receiving wind. Since the electric power thus obtained is AC power, it is converted into DC power by the power conversion means 30. And it can be supplied to the storage battery 7 after conversion.

  In this way, the light source 8 can emit light by the electric power stored in the storage battery 7. The light source 8 is controlled by the control means 31. The control means 31 is a means for controlling the light source 8 based on a detection signal from the illuminance sensor 32 and the like. Specifically, the light source 8 is controlled based on ambient brightness detected by the illuminance sensor 32. That is, the light source 8 is turned on when the surroundings are dark, such as at night or when fog is generated. Then, when the night dawns or the fog clears and the surroundings become bright, the light source 8 that has been turned on is turned off.

  As described above, since the light guide 8 of the guidance sign 1 is turned on when the surroundings become dark, the driver of the vehicle can be surely visually recognized at night or the like, and the vehicle can be safely passed. In addition, in the guidance sign 1 of the present embodiment, since it is controlled based on the ambient brightness detected by the illuminance sensor 32, power is not consumed wastefully and power is stably supplied to the light source 8 when necessary. Can be supplied.

  In addition, the inductive sign 1 of the present embodiment has a configuration in which electric power obtained by wind power generation and solar power generation is stored in the storage battery 7. In the case of only wind power generation, the necessary power cannot be stored if the windless period lasts for a long time, and in the case of only solar power generation, it is not possible to generate power at night, in cloudy sky or in the rain. Therefore, the inductive sign 1 of the present embodiment can be reliably charged as compared with either the wind power generation or the solar power generation.

  In addition, the guidance sign 1 of the present embodiment does not need to be supplied with electric power from the outside, and can therefore be used in depopulated areas and mountainous areas where there is no power supply facility near the road. In addition, in the guidance sign 1 of the present embodiment, it is not necessary to perform construction for supplying power from the power supply facility, so the cost for installation can be reduced, road regulation is not required during construction, and traffic There is no risk of disruption. Furthermore, since the inductive sign 1 of the present embodiment generates power using natural energy, it can suppress the emission of carbon dioxide and contribute to environmental problems.

  The guide sign of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. For example, in the above-described embodiment, the case 2 is formed in a substantially rectangular hollow box shape, but the outer shape can be appropriately changed as long as it is hollow. Moreover, in the said Example, a pair of opening parts 12 and 12 formed in case 2 are the substantially rectangular front-and-rear opening parts 13 and 14 formed in the center of the left-right direction of the front-back wall, and the front-back direction of a left-right wall Although the left and right openings 15 and 16 are formed in a substantially rectangular shape at substantially the center, the formation position, shape, and number of the openings can be appropriately changed as long as they are formed apart from each other in the horizontal direction. In this case, the vertical axis wind turbine 5 is appropriately disposed in the case 2 corresponding to the opening 12. Moreover, in the said Example, although the vertical axis windmill 5 was made into the crossflow type, it is not limited to this, A gyromill type etc. may be sufficient.

  Moreover, in the said Example, although the display part 9 was formed in the substantially rectangular shape elongated in the left-right direction, the shape can be changed suitably. The display unit 9 is provided on the upper wall of the case 2, but may be provided on the front wall, the lower wall, or the like of the case 2 instead of or in addition to this. For example, the display unit 9 may be formed in an arrow shape indicating one of the left and right directions and provided on the front wall of the case 2.

  Further, in the embodiment, as shown in FIG. 4, the guide sign 1 is continuously attached to the support column 27 of the guard rail 26. However, the present invention is not limited to this. Every other one may be attached.
