The front surface is formed as a vertical flat surface. An attachment frame 31 for fixing the game board 5 is integrally provided on the back surface of the front frame 2 so as to surround the window opening 4. The mounting frame 31 has a rectangular shape, and the game board 5 is placed and fitted on the upper surface of the lower shelf 31a. In addition, the game board 5 has the mounting frame 3
By a fixture (not shown) so that it does not fall off from 1,
It will be fixed firmly. The cover plate 30 inside the mounting frame 31 has an upper projecting plate portion 30a in which a portion surrounding the upper portion of the window opening 4 bulges rearward, and a portion surrounding one side of the window opening 4 is rearward. It is formed as a side projecting plate portion 30b that bulges out to the side. Therefore, the front surfaces of the upper overhanging plate 30a and the side overhanging plate 30b are recessed. The inner peripheral surface of the window opening 4, that is, the inner peripheral surfaces of the upper overhanging plate portion 30a and the side overhanging plate portion 30b, and on the back surface of the arcuate edge 4a, along the arcuate edge 4a. A rail guide groove 32 is formed. This rail guide groove 32
In the longitudinal direction of the front edge portion, an arc-shaped support step 33 having a width approximately one third of the rail width of the outer guide rail 18 and protruding from the surface of the rail guide groove 32 is formed. Have been. Also, the upper overhanging plate portion 30a and the side overhanging plate portion 30b are provided separately from each other without being continuous, and the lower end of one side of the upper overhanging plate portion 30a and the upper end of the side overhanging plate portion 30b. And a curvature adjustment space M having a predetermined width is formed. As a result, the rail guide groove 32 and the support step 33 are also cut at a substantially intermediate position in the longitudinal direction. Also,
Protrusions 35 having screw holes 34 projecting from the starting end and the end of the rail guide groove 32 are respectively located on the back surface of the cover plate 30. The outer guide rail 18 has a start end bent outward in a U-shape and a screw hole 36 at the end thereof.
A mounting piece 37 having an elongated hole 38 extending in parallel with the longitudinal direction of the outer guide rail 18 is integrally provided at the end portion. Then, the outer guide rail 18 is made to extend along the rail guide groove 32, and the screw hole 36 of the mounting piece 37 at the start end portion is formed into a screw hole 34 of a projection 35 provided at the start end side of the rail guide groove 32. The screw 40 is screwed into the screw hole 34 via the screw hole 36 as shown in FIG. Next, the rear edge of the outer guide rail 18 is brought into contact with the supporting step portion 33, and the long hole 38 of the mounting piece 39 on the terminal end is directly provided on the terminal 3 of the rail guide groove 32.

The screw 40 is screwed into the screw hole 34 via. As a result, the outer guide rail 18 is attached between the arc-shaped edge portion 4a slightly projecting from the rail guide groove 32 and the front surface of the game board 5. The surface forms an arc surface that forms a predetermined trajectory trajectory. Further, the outer guide rail 18 is connected to the firing rail 44 via a return ball discharge port 69 for guiding a pachinko ball which is fired once but returns due to a weak flying power or the like to the lower ball receiving tray 12. It becomes. As described above, the outer guide rail 18 is
Since it can be fixed at only two points, the start end and the end, it can be easily attached. As shown in FIG. 8, the outer guide rail 18 is supported only by contacting with the supporting step portion 33 only on the front edge side, and the unsupported portion is formed on the back surface by the entirety between the start end portion and the end portion. A space S is formed along at least the center in the rail width direction. As a result, the required elasticity is imparted to the outer guide rail 18, and the impact of the flying pachinko ball is absorbed particularly when the pachinko ball jumps out of the firing rail 44 and lands on the surface of the outer guide rail 18. Thus, the pachinko ball does not rebound unnecessarily during the flight, and the ball flying state becomes extremely good. In the present embodiment, the supporting step 33 is provided only on the front edge side of the rail guide groove 32. However, it may be provided on both the front and rear edge sides, and the outer guide rail 18 in the rail width direction may be provided. It is sufficient that the space S is formed at least along the rear surface of the central portion, so that the impact of the flying pachinko ball can be absorbed. The outer guide rail 18 is provided with a long hole 38 in a mounting piece 39 at the end thereof so that the mounting position can be freely adjusted. This naturally causes a dimensional error in forming the outer guide rail 18. However, if the length of the outer guide rail 18 is short with respect to the rail guide groove 32, the outer guide rail 18 is This is to prevent the mounting from being hindered even if an error occurs because the rear surface of the device does not come into contact with the rear surface and mounting becomes impossible. The upper overhanging plate portion 30a and the side overhanging plate portion 3
0b, a curvature adjustment space M is formed.
Inner peripheral surfaces of the upper overhanging plate portion 30a and the side overhanging plate portion 30b,
That is, the radius of curvature of the rail guide groove 32 is different. Therefore, when the outer guide rail 18 having a fixed radius of curvature is attached to the rail guide groove 32 at the time of manufacture, the curvature is different between the upper side and the lower side of the outer guide rail 18 so that distortion is reduced. As a result, the surface swells, and as a result, the ball flying state becomes unstable. Then, the surface of the outer guide rail 18 is smoothed by releasing the distortion in the curvature adjusting space M that can freely bend, and a stable ball flying state is to be ensured. FIG. 9 shows a front frame 2A according to another embodiment. It should be noted that since the front portion 2 has substantially the same structure as the front frame 2 according to the present embodiment, the same portions are denoted by the same reference numerals and a detailed description thereof will be omitted. In this front frame 2A,
The upper overhanging plate portion 30a and the side overhanging plate portion 30b are interchangeably attached to the front frame 2A. For this reason, a projection 42 having a screw hole 41 is provided at a predetermined location on the inner peripheral edge of the window opening 4A of the front frame 2A. On the other hand, screw holes 43 are formed at predetermined positions on the back surface of the upper overhanging plate portion 30a and the side overhanging plate portions 30b so as to correspond to the screw holes 41. Then, the upper overhanging plate portion 30a and the side overhanging plate portion 30b are arranged on the front surface of the window opening 4A, respectively, and the screw holes 41 are matched with the screw holes 43, respectively.
The screw 14 is inserted into each screw hole 43 through the screw hole 41 from the back side of the screw.
The upper overhanging plate portion 30a and the side overhanging plate portion 30b are attached by screwing. As described above, the upper overhanging plate portion 30a and the side overhanging plate portion 30b are interchangeably attached to the front frame 2A because of the inner peripheral surface of the upper overhanging plate portion 30a, that is, This is because the radius of curvature of the rail guide groove 32 is different depending on each ball game machine manufacturer, so that they can be dealt with. Further, if the front frame 2A is divided in this way, not only the members can be reduced in size and the design can be easily changed, but also the molding can be facilitated and the production cost can be reduced.
Further, it is conceivable to mount a lens member or a display device for a decorative effect or a display effect on the front surface of the upper overhanging plate portion 30a. This is because a model change is possible only by replacement, and it is also efficient when discarding. In addition, also about this front frame 2A, the end portion of the outer guide rail 18 is fixed to the rail guide groove 32 so that the mounting position can be freely adjusted.
At a substantially intermediate position in the longitudinal direction of the rail guide groove 32, a curvature adjusting space M in which the support step portion 33 is cut away and does not support the outer guide rail 18 is formed. Next, the firing rail 44 and the firing device 45 will be described.
