First claim

Opening claim text (preview).

What is claimed is: 1. A light guide plate unit, comprising: a first light guide plate, having: a first light guide plate body, formed by a transparent resin and having a light exit surface, wherein a surface on a side opposite to the light exit surface is provided with a prism; a glass layer, disposed on a side of the light exit surface; and an adhesive layer, disposed between the first light guide plate body and the glass layer, a first light source, located on a side surface of the first light guide plate and supplying light into the first light guide plate body; a housing, supporting the first light guide plate and the first light source; and a second light guide plate, disposed in parallel with the first light guide plate, wherein the housing has an opening, and the first light guide plate is disposed so that a side of the glass layer faces the opening to block the opening. 2. The light guide plate unit as claimed in claim 1 , wherein the adhesive layer is provided throughout an entirety between the first light guide plate body and the glass layer. 3. The light guide plate unit as claimed in claim 1 , wherein a surface on a periphery of the opening in the housing and a surface of the first light guide plate on the side of the glass layer are flush with each other. 4. The light guide plate unit as claimed in claim 1 , wherein a plurality of the second light guide plates is provided, being disposed in parallel with the first light guide plate on a side opposite to the glass layer of the first light guide plate; and a second light source is provided, supplying light into each of the plurality of the second light guide plates. 5. The light guide plate unit as claimed in claim 1 , wherein the first light guide plate has a through hole, and the light guide plate unit further comprises a switch part located at the through hole and receiving an operation. 6. A gaming machine, comprising the light guide plate unit as claimed in claim 1 .
