Description

  The present invention relates to a glass door of a gaming machine in which a glass plate is disposed in an opening of a resin door frame that is attached to the front side of the gaming machine body so as to be opened and closed.

  A glass door of a conventional general gaming machine (for example, a pachinko machine) is a glass for holding a glass plate on a resin door frame that is attached to the front side of the gaming machine body through a hinge mechanism or the like so as to be opened and closed. In many cases, the holding frame is provided integrally or separately, and the glass plate is disposed in the opening of the door frame by fitting the outer edge of the glass plate into the rail groove of the glass holding frame.

  In recent years, it has been required to increase the area of the glass window portion of the glass door (that is, the area of the opening portion of the door frame) in accordance with a request for expansion of the game area of the gaming machine. However, since the conventional glass door needs to ensure the strength of the door frame by forming the frame part surrounding the opening of the door frame to be somewhat wide, the width of the frame part of the door frame should be made too thin. There is a drawback that the area of the opening of the door frame (the area of the glass window portion) cannot be sufficiently expanded.

Therefore, as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-105522), the door frame is made of glass by fixing the outer edge portions of a plurality of glass plates to the resin door frame so as to be in pressure contact or in close contact with each other. There is a configuration in which the width of the frame portion of the door frame is reduced to increase the area of the opening portion of the door frame (the area of the glass window portion) by reinforcing the plate.
