Claims

[Claims for Utility Model Registration] 1. A transparent plate 2 is provided on the front side of an opaque substrate 1 on which a predetermined marking 11 is applied.
A sign 21 corresponding to the sign 11 is carved on the back side of the transparent plate 2 by V-grooving or roughening, and a plurality of light emitters 3, 3... are arranged around the transparent plate 2 so as not to face each other, A light-emitting sign board in which light from a light-emitting body 3 is irradiated into the transparent plate 2 from an end face of the transparent plate 2, so that the sign 21 emits light. 2. Transparent plates 2, 2 are provided on both sides of the opaque substrate 1, which has predetermined markings 11, 12 on the front and back surfaces, respectively, with the substrate 1 in between, and the back surface of each transparent plate 2, 2 faces the substrate 1. Signs 21 and 2 corresponding to the above signs 11 and 12 are formed by machining V-shaped grooves or roughening the surface.
2 is engraved, and a plurality of light emitters 3, 3... are arranged around the three-layer plate-like body of the substrate 1 and transparent plates 2, 2 so as not to face each other, and the light from the light emitters 3 is engraved on the transparent plate. 2,
A light-emitting sign board in which the signs 21 and 22 emit light by irradiating light into the transparent plates 2 and 2 from the end surfaces of the signs 2 and 2.
