DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball and ball game machine such as a pachinko machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine, for example, a pachinko machine, an outer rail for guiding a game ball fired by a firing device to an upper side of a game board is provided with other obstacles such as nails, a ball entrance, and a prize winning device. The game board is mounted on the front of the game board together with the various game components, and the game board is removably mounted on the front frame pivotally attached to the machine frame from the back side corresponding to the window hole. Then, in the case of a game, the launching device on the front frame side fires the game ball to the outer rail side along the game board, and guides the game ball to the upper side of the game board via this outer rail, A game ball is dropped downward along a game board, and if the game ball enters a ball entrance, a prize winning device, or the like during the fall, the game ball is paid out as a prize ball. In a conventional pachinko machine, inner and outer rails are made of a thin stainless steel strip, which is mounted on a game board via mounting nails.

[0003]

The conventional pachinko machines are:
Since the inner and outer rails are mounted on the front of the game board along with various game parts such as obstacle nails, entrance holes, prize winning devices, etc. Also need to be replaced together. That is, in the case of changing the game content in the pachinko machine, the arrangement and combination of various game parts such as a ball entrance and a prize device, conditions for forming a winning combination, and the like are changed according to the game content. The position, shape, etc. of the rails do not change regardless of the content of the game, and are always the same for each game.

However, in the conventional pachinko machine, since the outer rail is mounted on the game board together with other game parts, if the game board is replaced, the outer rail must be replaced together. In particular, the outer rail is made of a strip-shaped thin stainless steel material, which is attached to the game board using mounting nails, so the curved shape of the outer rail itself is difficult to determine before mounting, so handling Is very complicated, and if handled carelessly, it is easily deformed and becomes unusable.

Further, since the outer rail itself does not have a fixed shape, even when mounted on a game board, the outer rail is bent to a predetermined curvature by using a special machine, and a mounting nail on the edge side is driven into the game board. The mounting method must be adopted, and the operation is very complicated as compared with the mounting of various game parts such as other entrances and winning devices. As described above, the conventional pachinko machine has a drawback that it takes a great deal of time and effort to attach the outer rail to the game board, and it also takes a lot of time and effort to change the game contents by replacing the game board. Since the outer rails attached to the game board are exchanged and discarded by spending time, there is a disadvantage that not only is the material wasted, but also the manufacturing cost of the replacement game board increases significantly. .

The present invention has been made in view of the above-mentioned problems, and makes it easy to manufacture and mount an outer rail, and separates the outer rail from a game board when changing a game by replacing a game board. The purpose is to be able to exchange. *

When a game ball falling from the upper portion of the game board 5 falls to the lower portion without winning the prize device 10 or the like, the out ball receiving portion 43 converts the game ball to a so-called out ball when the game ball falls to the lower portion.
It is for guiding to 41. As shown in FIG. 9, a wear-resistant material layer 46 such as hard plating is formed on the upper surface of the out-ball receiving portion 43 to prevent abrasion due to contact with the game ball. The lower inner rail 44 is provided on the left side portion on the lower edge side of the lower decorative body 18 so as to face the outer rail 28, and between the lower inner rail 44 and the outer rail 28 by the firing device 22. A predetermined interval is ensured so that the fired game balls pass. The reinforcing portion 45 reinforces the lower decorative body 18 at a portion other than the lower inner rail 44, and is provided on the lower edge side of the connecting portion 42 so as to be continuous with the lower inner rail 44.

As shown in FIG. 3, inside the lower decorative body 18, mounting pins 47 are provided integrally with the connecting portion 42 at three positions on the left, right, left and right sides of the center portion.
Is inserted into the mounting hole of the game board 5, whereby the lower decorative body 18 is detachably attached to the lower portion of the game board 5. Note that a lamp 49 is provided inside the lower decorative body 18 via a substrate 48. As shown in FIGS. 3, 8, and 10, the left and right decorative bodies 16 and 17 each include a plate-shaped main body 50 having an outer side formed in a circular arc, and an upper lamp cover mounted on the front surface of the main body 50. 51 and a lower lamp cover 52, and are disposed on the left and right sides at a substantially central portion in the vertical direction of the game board 5.

The main body 50 has a substantially arc shape as a whole so that the outer side is curved at substantially the same curvature as the lower inner rail 44 of the lower decorative body 18, and the outer shape of the main body 50 has an upper lamp cover. The upper lamp cover 51 and the lower lamp cover 52 are mounted on the upper and lower sides of the main body 50 so that the outer shapes of the 51 and the lower lamp cover 52 follow. Of the left and right decorative bodies 16, 17, the outer side of the left decorative body 16 corresponding to the outer rail 28 is a main body part.
The upper inner rail 57 is composed of the three members 50, the upper lamp cover 51 and the lower lamp cover 52. The left decorative body 16 is disposed at a predetermined interval inside the outer rail 28 so as to form a path for a game ball between the outer rail 28 and the upper inner rail 57. At the upper end of the left decorative body 16, an extended inner rail portion 58 which is continuous with the upper inner rail 57 on the main body 50 side and extends upward along the outer rail 28 is integrally formed. The extended inner rail portion 58 has a strip shape, and a ball return preventing member 59 for preventing a game ball from returning is attached to an upper end portion thereof so as to protrude upward.

In the pachinko machine having the above-described configuration, when playing a game, the operating handle 23 of the firing device 22 is operated to fire game balls one by one. Then, the game ball enters between the outer rail 28 and the lower inner rail 44 from the ball introduction port 31 side of the decorative board 4, and the outer rail 28, the lower inner rail 44, and the upper inner rail
Through the passage between the outer rail 28 and the inner rail section 58.
After reaching the upper part of the game board 5 while being guided by the rail main body 32, it falls down along the game board 5. The game ball entered from the ball inlet 31 hits the lower part of the outer rail 28 and rises along its curved shape while being guided by the rail main body 32. However, it is difficult for the game ball immediately after firing to determine its trajectory. Therefore, on the lower side of the outer rail 28, the trajectory of the game ball is corrected or stabilized by the trajectory correction rib 34 provided on the rail main body 32.

The game ball falls from the upper part of the game board 5 while hitting an obstacle nail or the like. If the game ball wins in the prize opening 7 or the prize winning device 10 during this fall, the game ball is raised as a prize ball accordingly. Dispensed to dish 19. The game balls that have fallen to the lower part of the game board 5 without winning the winning opening 7 and the prize device 10 fall on the out ball receiving portion 43, and are collected by the out ball receiving portion 43 from the left and right sides to the center side. And is collected to the back side of the game board 5 through the out port 41.

According to the configuration of this embodiment, the front plate 26 of the decorative board 4 is formed with the opening 27 for accommodating various game parts such as the winning opening 7 of the game board 5 and the winning apparatus 10, and the opening 27 is formed. While the outer rail 28 is integrally provided on the inner periphery of the part 27, the decorative board 4 is mounted on the game board 5, so that upon production,
After separately assembling the game board 5 side and the decorative board 4 side, the decorative board 4 can be mounted on the game board 5. That is, a game board
On the 5th side, as shown in FIG. 8, as long as it fits in the opening 27 of the decorative board 4, in addition to the obstacle nails on the front of the game board 5, the variable symbol display device 6, the winning openings 7 to 9, the left winning Device 1
0, right winning devices 11 and 12, passing gate 13, starting gate 14,
Each play component such as the lower winning device 15, the left and right decorative bodies 16, 17 and the lower decorative body 18 is mounted.

On the other hand, as shown in FIG. 5, on the decorative plate 4 side, an outer rail 28 is provided in advance on the inner periphery of the opening 27 of the front plate 26.
Are integrally formed, and required parts such as an upper left decorative body 36, an upper right decorative body 37, and a lower right decorative body 38 are mounted outside the opening 27, respectively. Then, when the game board 5 side and the decorative board 4 side are assembled, respectively, the game board 5 is fitted to the back side of the decorative board 4 and fixed with mounting screws or the like to integrate them. As a result, as shown in FIG. 3, the game board 5 is inserted into the opening 27 of the front plate 26.
Side variable symbol display device 6, winning openings 7-9, left winning device 1
0, right winning devices 11 and 12, passing gate 13, starting gate 14,
Each play component such as the lower winning device 15, the left and right decorative bodies 16, 17 and the lower decorative body 18 can be accommodated. Next, this is fitted into the game board mounting frame 74 of the front frame 71 from the back side, and is fixed by the lock lever 76 with the back holding plate 75 applied thereto.

By using the decorative board 4 having the openings 27 in this way, it is possible to make a variety of novel designs such as making the decorative board 4 itself a good-looking shape. The overall design, including the board 5, is significantly improved.
In addition, since the decorative plate 4 has an outer rail 28 integrally on the inner periphery of the opening 27, the shape of the decorative plate 4 side including the outer rail 28,
The design design of both can be determined integrally while giving a change to the structure and the like, and a harmonious design is easy. In addition, since the decorative plate 4 is made of synthetic resin and the outer rail 28 is integrated with the decorative plate 4, the outer rail 28 can be easily formed at the time of forming the decorative plate 4, and a special machine can be used. This eliminates the need to attach the outer rail 28 alone, thereby improving workability during assembly and greatly improving work efficiency. Of course, the number of parts is also reduced.

In particular, the outer rail 28 has a very long rail body 32 in the form of a strip, but since it is integral with the front plate 26 of the decorative panel 4, it is handled like a conventional stainless steel. It is not necessary to pay special attention to this, and it can be handled relatively easily like other game parts, and the workability is also improved in this respect. Since the rail body 32 is provided with the wear-resistant material layer 35 on the guide surface for guiding the game ball, the rail body 32 is formed by the game ball despite the fact that the rail body 32 is made of synthetic resin integral with the decorative board 4. Damage can be prevented, and the durability of the decorative panel 4 and the rail body 32 can be improved.

FIG. 11 illustrates a second embodiment of the present invention, in which a decorative board 4 is fixed to a game board 5 and the two are not integrated, but a decorative board is provided.
The game board 4 and the game board 5 are separated from each other and are individually mounted on the game board mounting frame 74. That is, in this embodiment, when assembling, first, the decorative board 4 is fitted into the game board mounting frame 74 from the back side, and then the game board 5 is fitted into the portal frame portion 24 of the decorative board 4. Then, after that, the back holding plate 75 is applied and fixed by the lock lever 76. Also in this case, each game component is accommodated in the opening 27 of the decorative board 4, and the outer rail 28 is disposed around the game component. In addition, since the game board 5 is fitted into the gate-shaped frame portion 24 of the decorative board 4, the positioning of the outer rail 28 with respect to the game board 5 is very reliable, and the positional variation can be minimized.

When changing the game contents by replacing the game board 5, the fixing by the lock lever 76 is released, the back holding plate 75 is removed, and the game board 5 is removed from the portal frame portion 24 of the decorative board 4. I just need to extract it. Therefore, the decorative board 4 having the outer rail 28
Can be used as it is, which is very economical and rational without waste as in the prior art. If the decorative board 4 is soiled or damaged after long-term use, the decorative board 4 may be removed from the game board mounting frame 74 and replaced with a new one, and in such a case, the decorative board 4 may be replaced with the game board mounting frame. Can be easily removed from 74.

FIG. 12 illustrates a third embodiment of the present invention, in which the decorative board 4 is fixed to the game board mounting frame 74 of the front frame 71 with mounting screws 77. That is, the decorative board 4 has a mounting hole formed in the portal frame portion 24, and is fixed to the game board mounting frame 74 on the front frame 71 side by the mounting screw 77 inserted into the mounting hole. The game board 5 is detachably fitted into the portal frame portion 24 of the decorative board 4 from the back side.

Also in this case, when changing the game content, the game board 5 can be easily replaced. In particular, since the decorative board 4 is located on the game board mounting frame 74 side of the front frame 71, even when the lock lever 76 is released and the game board 5 is removed, the decorative board 4 does not move. With decorative board 4
The work at the time of replacement is very easy without being detached. If the decorative board 4 is soiled or damaged, it can be easily replaced simply by removing the mounting screw 77.

FIG. 13 illustrates a fourth embodiment of the present invention. The outer rail 28 is formed of a metal plate such as a stainless steel plate so that the rail main body 32 and the mounting base 33 have an L-shaped cross section. The outer rail 28 is insert-molded on the decorative panel 4 so as to match the inner peripheral edge of the opening 27 of the front panel 26. The mounting base 33 may be provided over the entire length of the outer peripheral side of the rail main body 32, or may be provided at regular intervals. In this case, when forming the decorative plate 4, the outer rail 28
Can be made relatively easily,
In addition, the game board 5 can be used in the same manner as in the above-described embodiments. Therefore, the outer rail 28 does not necessarily need to be formed integrally with the front plate 26 of the decorative panel 4.

The present invention is not limited to each embodiment, and it goes without saying that various modifications are possible. For example, the gate-shaped frame portion 24 of the decorative board 4 may be formed in a rectangular shape over the entire circumference of the front plate portion 26, or in the case of a structure in which the decorative board 4 is fixed to the game board mounting frame 74 of the front frame 71, The decorative panel 4 may be constituted only by the front panel 26 having the outer rail 28 on the side of the opening 27 by omitting the gate-shaped frame 24 entirely. The game board 5 may be attached to and detached from the window hole 73 of the front frame 71 from the front side of the front frame 71. Furthermore, the wear-resistant material layer 35, 4 on the guide surface
For 6, a thin metal plate such as stainless steel may be used.
In this case, if a metal plate is inserted during molding, the outer rail 28 and the like can be easily manufactured.
Further, the present invention can be similarly applied to various types of ball game machines other than pachinko machines.

[0029]

According to the present invention, at the center of the lower end of the decorative board 4,
A ball introduction port 31 for introducing a game ball from the firing device 22 into the game area is provided, and an outer rail 28 for guiding the game ball from the ball introduction port 31 to the upper side of the game area is formed integrally with the decorative board 4. Therefore, it is not necessary to provide the outer rail 28 on the game board 5 as in the related art, and the outer rail 28 can be integrally attached to and detached from the decorative board 4. Therefore, the outer rail 28 is made of a synthetic resin
It can be manufactured as required, such as by being integrally formed with the mold or by insert molding, and its manufacture and mounting are easy. In addition, since the frame portion 24 on which the game board 5 is detachably fitted from the back side is provided integrally on the outer peripheral side of the decorative plate 4, the decorative plate 4 can be reinforced by the frame portion 24, and the strength of the decorative plate 4 can be reduced. Larger and easier to handle. Moreover, since the game board 5 is detachably fitted to the frame portion 24, the positioning of the decorative board can be easily performed. Furthermore, since the decorative plate 4 is integrally provided with the outer rail 28 in addition to the outer peripheral side frame portion 24, the decorative plate can be reinforced by the outer rail 28.

Also, in the present invention, the decorative board 4 is provided on the front frame 71 side, and the game board 5 is detachable from the front frame 71. Therefore, when the game board 5 is replaced to change the game content. In this case, the game board 5 side can be replaced by being separated from the outer rail 28, which is less wasteful and more economical than before. Further, in the present invention, the decorative plate 4 includes a front plate portion 26 having an opening 27 corresponding to the game area, and a frame portion 24 integrally formed on the outer peripheral side of the front plate portion 26. The game board 5 is made to be detachable from the decorative board 4 so that the game board 5 fits into the frame section 24 on the back side of the face plate section 26, so that the positioning of the outer rail 28 with respect to the game board 5 is ensured. Can be.
