Title
(EN) LIGHT EMITTING DISPLAY DEVICE, METHOD OF MANUFACTURING LIGHT GUIDE PLATE, AND GAME MACHINE
(JA) 発光表示装置、導光板の製造方法および遊技機
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a light emitting display device and a game machine capable of reliably preventing interference fringes from being visually recognized in a visible area even when a warp occurs in a light guide plate.

SOLUTION: A first light guide plate 11 and a second light guide plate 12 are arranged to face each other, and a visible area of a surface of the second light guide plate 12 facing the first light guide plate 11 is provided with a microprojection group comprised of a plurality of microprojections 17. The plurality of microprojections 17 have such an arrangement and a height that ensure a distance, by which interference fringes are prevented from becoming visible, between the first light guide plate 11 and the second light guide plate 12 by coming into contact with the second light guide plate 12. Further, the microprojection group and dimples 16, the dimples being formed on the second light guide plate 12 to constitute a pattern portion, are formed on the same surface.

【課題】導光板に反りが発生しても視認領域において干渉縞が視認されることを確実に防止することができる発光表示装置および遊技機を提供する。
【解決手段】対向して配置された第1導光板11および第2導光板12のうち、第2導光板12における第1導光板11との対向面の視認領域に、複数の微小突起17からなる微小突起群が設けられている。複数の微小突起17は、第2導光板12と接触して第1導光板11と第2導光板12との間に干渉縞が視認されない距離を確保する高さおよび配置を有する。そして、微小突起群と第2導光板12に形成された図柄部を構成するディンプル16とは同じ面に形成されている。
