Claims

[Scope of utility model registration request]

A large number of marking grooves are formed close to each other on the back surface between the opposing side walls, substantially parallel to the center line between the two side walls,
and the large number of marking grooves formed in close proximity to each other,
As the opposing side walls get closer to the center line, the depth gradually increases in a stepwise manner,
The shape of the groove bottom according to a cutting plane perpendicular to the core axis of the groove is formed by a transparent plate having an arcuate concave curve, a shape-retaining substrate applied to the back surface of the transparent plate, and a shape-retaining substrate applied to the transparent plate and its back surface. an outer enclosure having a channel-shaped cross section, which sandwiches the outer peripheral edge of the shape-retaining substrate from the front and back, and forms and surrounds a space for installing a light emitter between the walls of both sides of the plates; Several light emitters are installed along the wall surfaces of the opposing side walls in the light emitting body arrangement installation space, each of which allows irradiation light to enter the transparent plate through the wall surface, and the incident irradiation light A light-emitting sign board characterized in that light is diffusely reflected to the outside of the surface of the transparent plate by an arcuate concave curved surface for forming the bottom of the marking groove formed by the arcuate concave curve.
