[0002]

2. Description of the Related Art Conventionally, a frame structure of a pachinko machine has an outer frame and an outer frame provided with an inner frame on which a game board and other mechanisms are mounted so as to be openable and closable. A glass frame was attached to the front of the board. However, recently, instead of a metal glass frame to illuminate the front of the pachinko machine, one made of synthetic resin has been proposed,
Since this single synthetic resin frame has problems in security and strength, a configuration in which a synthetic resin decorative resin frame 2 is attached to the front side of a metal glass frame 1 as shown in FIG. In order to attach the decorative resin frame 2 to the glass frame 1,
Several other screw holes 3 are penetrated, and on the back side of the decorative resin frame 2, other several screw receiving recesses 4 are formed corresponding to the screw holes 3 of the glass frame 1. 3 and screw receiving recess 4
Are screwed into each hole 3 from the glass frame 1 side in a state where
Threaded.

[0003]

However, in order to assemble the decorative resin frame 2 to the conventional glass frame 1, it is necessary to fix the glass frame 1 with a large number of screws 5. When trying to discard the glass frame 1 on which the glass frame 2 is mounted, there are many places where the screws 5 are fixed, so that it is extremely difficult to separate the glass frame 1, and there is a problem that if the glass frame 1 is left as it is, it causes pollution. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has an attachment / detachment structure of a glass frame and a front decorative resin frame in a pachinko machine capable of easily attaching and detaching the decorative resin frame to / from the glass frame. The purpose is to provide.
