  Here, the cutting portions 21 provided on both sides of the light guide plate 2 have the positions provided on the both sides alternately, so that the light L1 and L2 and the like incident on the light guide plate 2 are cut. When the light is scattered and emitted to the outside of the light guide plate 2, the cutting portion 21 on the opposite surface is prevented from interfering with smooth light emission of the guidance display portion 3.

  FIG. 3 is a cross-sectional view showing a BB cross section of the solar cell precursor shown in FIG. 1. The solar cell drive unit 20 is provided with a solar cell 4 having solar cells on the upper surface of the frame W2, and further, the storage means 5, which is an electric double layer capacitor, the seismic sensor 6 and the brightness in the frame W2.

  FIG. 4 is a block diagram showing a series of operations of the self-luminous guidance device 100. Normally, when the brightness sensor 71 of the control unit 7 detects that it is nighttime, an internally illuminated sign S emits light to provide information drawn to the surroundings. Here, the induction light emitter 1 does not need to emit light, but may be in a light emitting state. When an earthquake occurs and the seismic sensor 6 detects a seismic intensity greater than a threshold value that may turn into darkness due to a power failure, for example, an earthquake with a seismic intensity of 3 or greater, a signal is emitted from the seismic sensor 6 to the control unit 7, The control unit 7 that receives the signal starts or maintains the power supply to the induction light emitter 1 and causes the induction display unit 3 to emit light.
