DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine, a slot machine, a smart ball, and other front opening / closing doors for amusement machines.

2. Description of the Related Art For example, the front opening / closing door of a pachinko machine comprises a square door frame and a pair of front and rear transparent plates fitted in the frame, through which a player can see through the play board surface. I have. However, since the surface of the transparent plate causes a specular reflection phenomenon (glare) and a reflection phenomenon of external light, it is difficult for a player to see the play board surface. Therefore, for example, Japanese Patent Application Laid-Open No. H10-165600 proposes a method in which one antireflection filter is sandwiched between transparent plates or one antireflection film is adhered to the back surface of the transparent plate or the front surface of the transparent plate. However, since the reflection and reflection of light occur on each surface of the transparent plate, the method of sandwiching a filter between two glass plates or the method of attaching one antireflection film have insufficient effect of preventing reflection.

Films having an antireflection function are usually
Since a pair of transparent plates are used as the opening / closing door, two films are bonded to one transparent plate. When one film is bonded to one transparent plate, the antireflection effect is insufficient, and it is sufficient to bond at most four films to a pair of transparent plates. In addition to the anti-reflection effect, in order to prevent the player from being injured by the broken piece of the transparent plate when the transparent plate is damaged, the front of the opening / closing door (front side of the player) One anti-reflection film and at least one anti-reflection film on one side of the door at the back of the opening / closing door (of the transparent plate at the back of the player) are required.
