Maintenance of each device on the back of the main body 2 is facilitated. A game board 5 is disposed in the game window hole of the front frame 3 of the gaming machine body 2, and a ball tray 6, a launch handle 7, and the like are provided below the front frame 3.
[0011]
As described above, the rectangular outer frame 10 is to which the gaming machine main body 2 including the gaming board of the pachinko gaming machine is attached, and relates to the main part of the present invention. The configuration of the rectangular outer frame 10 will be described with reference to FIGS.
The rectangular outer frame 10 is configured by assembling left and right vertical frame rods 11a and 11b and upper and lower horizontal frame rods 20a and 20b. Here, the vertical frame rods 11a and 11b are made of an aluminum casting (aluminum die cast), and connecting ribs 12 and 12 projecting inward are formed at the upper and lower ends. The connecting ribs 12 and 12 have a flat tube shape having a square cross section, and connecting holes 13 and 13 are formed on the side surfaces thereof. Further, the inner surface of the vertical frame ridges 11a and 11b is formed with a molding groove surface 14 in order to make the thickness dimension the same as that of a conventional wooden frame and to keep the substantial thickness uniform and thin, and In order to maintain the strength, reinforcing ribs 15 in the lateral and oblique directions are formed. In addition, a hinge portion 16 provided with a shaft hole 17 is formed on one vertical frame rod 11a so as to pivotally support the gaming machine main body 2 so as to be freely opened and closed. Furthermore, a locking projection piece 18 that links the gaming machine main body 2 projects inwardly on the inner surface of the vertical frame rod 11b.
[0012]
On the other hand, the horizontal frame rods 20a and 20b are made of a synthetic resin material, and fitting projections 21 and 21 that are fitted into the connecting ribs 12 and 12 are formed at both ends thereof. Screw holes 22, 22 into which fixing screws are screwed from the connection holes 13, 13 of the connection ribs 12, 12 are formed on the side portions of the fitting protrusions 21, 21. Moreover, the nail holes 23 and 23 for assembling | attaching to an installation island in the left-right position are formed along the longitudinal direction. Thus, since the horizontal frame rods 20a and 20b are formed of a synthetic resin molded body, the nail holes 23 and 23 can be easily formed.
[0013]
In this configuration, the fitting protrusions 21 and 21 formed at both ends of the upper and lower horizontal frame rods 20a and 20b are fitted into the upper and lower coupling ribs 12 and 12 of the vertical frame rods 11a and 11b, and the coupling holes 13 are inserted. The rectangular outer frame 10 is assembled by screwing attachment screws into the screw holes 22 and 22 from the screw holes 13 and 13. In this assembled state, the gaming machine main body 2 is supported so as to be openable and closable by a linkage shaft that is inserted into the shaft hole 17 of the hinge portion 16 formed in the vertical frame rod 11a. Further, as shown in FIG. The provided movable hook 9 is engaged with the locking protrusion 18. As a result, the gaming machine main body 2 is mounted on the front portion of the rectangular outer frame 10 and various members provided on the back surface of the gaming board surface 5 face the rectangular outer frame 10.
[0014]
Thus, the rectangular outer frame 10 is assembled by fitting the fitting protrusions 21 and 21 into the connecting ribs 12 and 12 and screwing, and does not require a separate member such as a metal fitting. The number of parts is reduced, and the rectangular outer frame 10 can be made inexpensive, and the assembly is facilitated.
[0015]
And the rectangular outer frame 10 assembled | attached in this way will be juxtaposed on an installation island using each nail hole 23 formed in the horizontal frame collars 20a and 20b.
[0016]
In the rectangular outer frame 10 having such a configuration, since the vertical frame rods 11a and 11b are formed by an aluminum casting (aluminum die cast), the rigidity is strong. Moreover, the rectangular outer frame 10 supports the entire weight of the gaming machine main body 2 by the reinforcing ribs 15 and the hinge portions 16, but the reinforcing ribs 15 and the hinge portions 16 are vertical frames as cast aluminum products. Since it is integrally formed with the flanges 11a and 11b, the required holding strength can be ensured without using a separate L-shaped bracket.
[0017]
On the other hand, the horizontal frame rods 20a and 20b are formed of a synthetic resin material.
For this reason, the whole rectangular outer frame 10 can be made lightweight. Further, the nail holes 23, 23, etc. can be easily formed.
[0018]

The vertical frame の and the upper and lower horizontal frame ridges that are passed between the upper and lower connecting ribs and fixed to the connecting ribs at both ends are made into aluminum frame cast (aluminum die cast). By connecting the horizontal frame rods via the integrally formed connecting ribs, sufficient assembly strength can be maintained.
[0019]
Further, as a means for connecting the vertical frame rod and the horizontal frame rod, the connecting ribs of the vertical frame rod are formed in a cross-sectional shape, and insertion protrusions are formed at both ends of the horizontal frame rod. When it is configured by being fitted and fixed, it can be easily assembled by internal fitting work and screwing.
[0020]
Here, when the horizontal frame cage is made of synthetic resin, it is possible to prevent the outer frame from becoming heavy, and it is possible to prevent the outer frame from becoming heavy, and by forming a long hole-like nail hole, etc., the optimum shape can be easily assembled to the installation island It becomes easy to mold into.
[0021]
In addition, when a locking projection piece that links the main body of the gaming machine is formed on the inner surface of the vertical frame rod by integral molding using an aluminum casting (aluminum die cast), the metal L-shaped locking projection piece is fixed. Therefore, high strength capable of supporting the load of the gaming machine main body can be realized.
[0022]
Furthermore, when a hinge portion that pivotally supports the gaming machine main body so as to pivot is integrally formed at the upper end of one of the vertical frame rods, the hinge portion will be inserted into the main body when the gaming machine main body is opened. However, since it is formed integrally with a vertical frame made of an aluminum casting (aluminum die cast), sufficient holding strength can be guaranteed.
