Description of the Related Art As is well known, the basic structure of a pachinko machine has not changed much since its birth, and it has a frame-like frame with a wooden outer frame fitted with a glass plate so that the inside can be seen through. The front frame is hinged so that it can be opened and closed, and a game board having an accessory, a winning opening and an outlet, and an obstacle nail is formed behind the window. And conventional pachinko machines are wood (plywood)
Is used as a structural material. However, in recent pachinko machines, there is a tendency to prefer large-sized accessories, and electric parts are often used for accessories, and these are controlled by a microcomputer. There is a shortage. In addition, pachinko machines in recent years have been able to win a large amount of prize balls when a big hit occurs, so there is no end to illegal games that illegally aim for prize balls. Moreover, the damage amount of the game store when the illegal game is played is large. Further, in recent years, there has been a demand for conservation of nature and there is a tendency to reduce the amount of wood used. Therefore, a pachinko machine using a structural material instead of wood is desired. Then, for example, Japanese Patent Laid-Open No. 62-53679.
The Japanese Patent Laid-Open Publication proposes that the front frame is made of an extruded aluminum material. In addition, JP-A-63-5
Japanese Patent No. 774 proposes a conventional glass frame and a glass plate formed of a synthetic resin.
