Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basic structure of a gaming machine such as a pachinko gaming machine in which a game is played using a gaming medium.

[0002]

2. Description of the Related Art A pachinko gaming machine, which is an example of a gaming machine,
Members such as an upper plate panel with an upper plate at the bottom and a lower plate panel with a lower plate and a firing handle are held on the front part of the front frame, and a game board is attached to the opening part of the front frame. The gaming machine main body is attached to the outer frame from the front, and various mechanisms mounted on the back surface of the game board main body are surrounded by the outer frame. This front frame is used when trouble occurs inside the gaming machine.
By releasing the locking device, it can be opened to the outer frame.

[0003]

In the conventional structure,
The front frame is made of synthetic resin, and the upper plate panel and the lower plate panel to which various members are attached are fixed to the surface thereof as described above. Also, in the opening of the front frame, various game parts are mounted on the front surface, and on the back surface are a unit of the pattern display device, various boards for controlling the game machine, a drive source for driving the various game parts, and the like. The mounted game board is held. Therefore, a large load is applied to the front frame, and since it is made of a synthetic resin material and has no durability, it is easily deformed by a constant load, and opening and closing of the outer frame and opening and closing of the glass frame become difficult. There is a problem such as. Further, since the front frame is formed by a unique design, it cannot be reused for a new stand, and there is a drawback that resource recycling is impossible.

On the other hand, as disclosed in Japanese Unexamined Patent Publication No. 62-47382, there has been proposed a structure in which a front frame is constructed by assembling a rod material made of an aluminum extrusion mold material. However, in such a structure, it is necessary to connect the rods with bolts or the like, and there is a problem that assembly is troublesome. In particular, since it is an extruded aluminum material, its cross-sectional shape can secure some design characteristics, but it has limitations compared to those made of synthetic resin materials, and it is a high-quality pachinko machine that is currently oriented. As a gaming machine, it is not qualified. An object of the present invention is to provide a gaming machine, such as a pachinko gaming machine, which has a gaming machine main body rectangle that is robust, easy to assemble, and excellent in recycling.

[0005]

The present invention is provided with a game board holding base frame integrally formed by aluminum casting (aluminum die casting) and having an opening formed therein for mounting the game board. It is characterized by.

In such a structure, the game board holding base frame,
Since it is integrally formed by aluminum casting,
It is possible to hold a game board, which has a large load due to a mechanism plate or the like attached to its back surface, with sufficient strength. Further, the process of assembling the rod material is not necessary. Further, the game board holding base frame has high durability, can be reused several times, and can easily be converted to a new table by exchanging the game board, etc., and has high resource recycling property.

In such a structure, a game window hole facing the game board surface is formed on the front surface of the game board holding base frame which is integrally formed by aluminum casting and has an opening formed therein for mounting the game board. The synthetic resin decorative panel is provided, and at least the upper plate panel equipped with the upper plate is provided so as to cover the lower part of the opening of the game board holding base frame at a position directly below the decorative panel, and A configuration is proposed in which a lower plate panel attached with at least a lower plate is arranged so as to cover the lower front part of the game board holding base frame at a position directly below the upper plate panel. That is, it is a game board holding base frame made of an integrally molded aluminum product that is inferior in design but is easy to form, and is covered with a decorative panel made of synthetic resin or the like that can ensure high design.

In this structure, since the decorative panel made of synthetic resin is separately formed and adhered, the design is improved even though the aluminum cast base frame is used as the base material. Can be made. In particular, in order to reduce the weight of the game board holding base frame, the game board holding base frame is made thin,
Moreover, even if the outer edge is a wide edge and the front and back surfaces are concave (see FIG. 4), since it is covered by the decorative panel, the appearance does not deteriorate. That is, by using the decorative panel made of synthetic resin, there is no restriction on the form of the game board holding base frame, and as a result, it is possible to reduce the weight of the game board holding base frame made of an aluminum casting. Further, since it is configured only by disposing the decorative panel, the upper plate panel and the lower plate panel on the front surface of the game board holding base frame, the assembling becomes easy.

Here, the synthetic resin decorative panel, the upper plate panel and the lower plate panel, which are adjacent to each other in the vertical direction, may be integrally molded in an appropriate combination.

Further, a ball discharge port communicating with the lower plate and a ball passage provided on the back side of the game plate are provided at a position where the lower plate of the game board holding base frame communicates with the lower plate. The discharge port receiving portion communicating with the ball discharge port may be integrally formed with the game board holding base frame by aluminum casting. In this case, since the discharge port receiving part is also integrally formed by aluminum casting,
Since it is not necessary to separately form and attach the discharge port receiving portion, the number of parts is reduced and the number of assembling steps is reduced.

On the other hand, a positioning hole may be formed in a fixing member that holds the upper plate panel, and a positioning protrusion that fits into the positioning hole may be formed integrally with the game board holding base frame. That is, since the positioning protrusion is integrally molded with the game board holding base frame by aluminum die casting, it can always be accurately formed at the same position with respect to the game board holding base frame. In this respect, in the conventional configuration, since the front frame is made of a synthetic resin material, a load is applied when opening and closing the upper plate panel, and therefore the fixing member cannot be directly fixed to the front frame having low strength. The metal peripheral frame fitted around the opening is bent or welded in the lower part, and is disposed by welding. Therefore, the machining of the metal peripheral frame is troublesome, and in the case of retrofitting, the position adjustment at the time of assembly is troublesome due to deformation or error during the formation. With such a configuration, these problems will be solved.

[0027]

As described above, the present invention is provided with a game board holding base frame integrally formed by aluminum casting (aluminum die cast) and having an opening formed therein for mounting the game board. (Structure of claim 1) Therefore, it is possible to hold a game board having a large load by attaching a mechanism plate or the like to the back surface with sufficient strength. That is, the game board holding base frame is integrally formed of an aluminum cast product and can be robust and retain sufficient strength. Even if various members are attached and a large load is constantly applied, it is deformed. It is possible to stably connect and open each member and to open and close the outer frame and the glass frame without difficulty. Further, since the durability is improved, it can be reused several times, and it becomes easy to convert to a new stand by exchanging the game board and the like, and the resource recyclability is high. Further, the process of assembling the rod material is not necessary.

In such a structure, a synthetic resin decorative panel having a game window hole facing the game board surface is provided on the front surface of the game board holding base frame made of aluminum casting, and at a position directly below the decorative panel. In the structure (the structure of claim 2) in which the upper plate panel is arranged and the lower plate panel is arranged directly below the upper plate panel, a synthetic resin decorative panel is used to form an aluminum cast base as a base material. High designability can be maintained despite the use of the frame. In particular, in order to reduce the weight of the game board holding base frame, the game board holding base frame is made thin, and the outer edges are wide edges. It doesn't get bad. That is, it is easy to reduce the weight of the gaming machine body. Also, because the game board holding base frame is provided with a separate synthetic resin decorative panel, it is easy to attach functional parts such as speakers to the panel itself, and the game machine main body is made highly functional. Can be planned. Furthermore, since the decorative panel, the upper plate panel and the lower plate panel are simply provided on the front surface of the game board holding base frame, the assembly is easy.

At the portion where the lower plate of the lower plate of the game board holding base frame is arranged, a ball discharge port communicating with the lower plate and the ball discharge port are covered from the back side and are arranged on the back side of the game plate. When the discharge port receiving portion that connects the ball passage to the ball discharge port is integrally formed with the game board holding base frame by aluminum casting (configuration of claim 4), the discharge port receiving portion is separately formed. Moreover, it is not necessary to attach it, the number of parts is reduced, and the assembling becomes easy.

In the case where the positioning member is formed with a positioning hole in the fixing member for holding the upper plate panel, and the positioning protrusion that fits into the positioning hole is formed integrally with the game board holding base frame (claim 5). In addition, since the positioning protrusion is integrally molded with the game board holding base frame by aluminum die casting, it can always be accurately formed at the same position with respect to the game board holding base frame. In this respect, in the conventional configuration, since the gaming machine body is made of a synthetic resin material, a load is applied when opening and closing the upper plate panel, so it is not possible to directly fix the fixing member to the gaming machine body with low strength. Since this is not possible, the metal peripheral frame fitted around the opening is bent or welded in the lower part, and is disposed by welding. Therefore, the machining of the metal peripheral frame is troublesome, and in the case of retrofitting, the position adjustment at the time of assembly is troublesome due to deformation or error during the formation. In such a configuration, there is an advantage that the processing is not troublesome and the assembling is not troublesome.
