LIGHT GUIDE PLATE AND INDICATING INSTRUMENT WITH THE SAME
First Claim
1. A light guide plate comprising:
- a light emitting section that is arranged so as to overlap a dial which is provided with translucent designs;
a light guide section that is connected to the light emitting section and has a light incidence surface on which light of a light source is incident; and
a reflective section that reflects light, which is guided to the light emitting section by the light guide section, toward a first surface facing the dial of the light emitting section, and is provided on a second surface facing the first surface of the light emitting section,wherein, in the reflective section provided on the second surface, a plurality of striated convex or concave portions are formed so as to be arranged in a direction intersecting a traveling direction in which the light travels through the light emitting section, and be in contact with each other, and furthermore a plurality of reflective bodies formed of the plurality of striated portions are provided at intervals, andthe plurality of striated portions are formed so as to cause incident light to pass therethrough while refracting the light toward the first surface and then reflect the light in a direction perpendicular to the dial.

Abstract
A light guide plate includes a light emitting section having an arc shape in plan view which is arranged to overlap a dial. On a rear surface of the light guide plate, a reflective section which reflects light traveling through the light emitting section toward a front surface is provided. In addition, in the reflective section, plural reflective bodies formed of plural ridges, which are arranged in a direction intersecting the traveling direction of light traveling through the light emitting section so as to be in contact with each other in a width direction thereof and are provided to be convex on the rear surface, are provided at intervals. The plural ridges are formed so as to cause incident light to pass therethrough while refracting the light toward the front surface and reflect the light in a direction perpendicular to the dial.
