<P>PROBLEM TO BE SOLVED: To provide self-light-emitting guidance equipment which maintains a guidance function over a long period of time by enabling escape guiding using light emission to be performed with low power consumption, and an in-disaster guidance system. <P>SOLUTION: Light is introduced into a light guide plate 2 by making a guidance light-emitting part 1 emit the light, so that a guidance display part 3 with a large area emits the light. This enables the escape guidance on occurrence of an earthquake at night to be surely performed by using a small quantity of light, and enables the guidance function to be maintained over a long period of time by suppressing the power consumption when a guidance light emitter 1 emits the light. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
