BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine and a slot machine game machine, and more particularly, to a plurality of control boards provided in these game machines in one case. The present invention relates to a gaming machine having a control board storage case structure capable of being stored in a game machine.

[0002]

2. Description of the Related Art Conventionally, a gaming machine such as a pachinko gaming machine, a slot machine gaming machine, etc., is provided with a plurality of control boards for controlling gaming machines and the like of the gaming machines. It is stored in a base storage case (one control base is stored in one control base storage case), and attached to a predetermined position of the gaming machine.

For example, in a conventional pachinko machine, 1
A plurality of control board cases accommodating two control boards are attached to the back of the pachinko machine main body, and are arranged in a substantially planar manner. The types of control bases tend to increase with the increase in electric game machines installed in pachinko machines, and the types of bases include main control base, display control base, relay base, voice control base, and lamp control base. Etc. are exemplified. In addition, at present, some of these control board cases are provided with countermeasures against fraud to avoid unauthorized modification of the control board.

[0004] Each of the control board storage cases is configured such that extra space remains after the control board is stored.

[0005]

The installation location of the control board is also limited, so it is almost impossible to mount multiple control board storage cases in a plane, and most of the space inside the gaming machine is occupied by the control board storage case (control board). It is the current situation.

Even if the control board storage cases are stacked in a plurality of stages (because the extra space of each control board storage case also overlaps), the control board storage cases are only increasing rearward, and the installation of the gaming machine requires a structure. The above inconvenience may occur. In addition, wiring and the like are becoming complicated with the number of control board storage cases. These factors have significantly reduced the efficiency of maintenance and production of gaming machines.

Further, if countermeasures are taken against each of these many control board storage cases, this may cause a reduction in productivity.

The problem to be solved by the present invention is that the storage space of the control board can be effectively used without increasing the space, and the wiring to a plurality of control boards arranged at various places on the back of the gaming machine is also required. The purpose of the present invention is to provide a gaming machine that can be concentrated on any of the control base storage cases, thereby simplifying the configuration of the entire gaming machine and improving the production efficiency during assembly and manufacturing of the gaming machine and the efficiency during maintenance. It is to plan.

Another object of the present invention is to simplify the connection relationship between the control boards in the control board storage case.

According to this gaming machine, a plurality of control bases are stored in a single control base storage case, and these control bases are electrically connected by the connection means of the control base storage case. Despite the fact that many control boards are provided in the gaming machine, the wiring between the control boards is simplified, and the efficiency during the production and maintenance of the gaming machine is improved.

In this case, the connecting means includes:
For example, use of a lead wire or connection with a connector is conceivable. However, as described in claim 2, a printed wiring circuit is formed on the wall surface of the control board storage case, and each control circuit is connected via the printed wiring circuit. If the boards are electrically connected, the wiring work can be further simplified. In this case, the printed wiring circuit may be provided on the inner wall surface of the control board storage case, or may be double-sided printed wiring provided on the inner and outer wall surfaces. Alternatively, a printed wiring circuit may be provided on the outer wall surface (single-sided printed wiring), and each control board in the case may be electrically connected to the printed wiring circuit by a lead wire or the like.

According to a third aspect of the present invention, the control board storage case includes a base case having an open side and a cover attached to the base case. By adopting a configuration in which a plurality of support guide members having guide grooves for inserting the control boards in the same oblique direction on the wall surface are arranged side by side, storage of each control board is facilitated and orderly storage is also possible. A state will be obtained.

According to a fourth aspect of the present invention, at least one edge of one of the control boards is protruded from an exposed opening groove formed in a wall surface of the control board storage case, and the control board has a protruding surface on the outside thereof. If the wiring connector for the connection is provided, the wiring connection with other control bases, gaming machines, and the like provided on the back surface of the gaming machine can be smoothly performed without difficulty.

Still further, as described in claim 5, each of the control boards stored in the board storage case is at least partially overlapped when viewed from a direction perpendicular to the row direction. If provided, the control board storage space can be further downsized.

According to the present invention, one of the control bases is a main control base for controlling at least the game contents of the gaming machine as a whole, and the control base storage case is provided in the control base storage case. If a means for preventing fraud is provided to prevent the cover from being opened fraudulently, the measures for preventing fraud will also be thorough.

According to the gaming machine provided with the “0”, the first
Since the fourth to fourth control boards 121a to 121d are arranged in a row at a small interval in the same direction and inclined, the space in the control board storage case 100 is effectively used without wasting. Since the control boards 121a to 121d are arranged in a state where they are slightly shifted from each other and are partially overlapped with each other, a compact storage space can be achieved.

In the control board storage case 100, the connection between each control board (first control board 121 a to fourth control board 121 d) is connected to the lower wall plate 1 of the storage board 100.
Since this is performed via the wiring circuit 141 printed on the thirteenth surface, the trouble and trouble of wiring connection between the control boards can be saved, and the wiring connection work between the control boards can be made more efficient.

Further, the control bases 121a to 121d stored in the control base storage case 100 are stopped by stopper pieces 127 provided on the respective base surfaces by the support guide members 123a to 123d, and the cover 130
Is not accidentally moved in the storage case by being pressed by the fitting convex surface 133, and the connection between the respective control boards becomes reliable.

When each of the control boards 121 a to 121 d is stored in the control board storage case 100, each control board is connected to each of the support guide members 123 a to 123 a of the base housing 110.
It suffices to insert the cover 130 into the insertion guide groove 122 of 123d and 124a to 124d and screw the cover 130 to the base housing 110, so that there is also an advantage that the work of storing the control board can be performed easily.

The size of the storage case varies depending on the degree of inclination and the degree of overlap of each of the control substrate storage cases 121a to 121d stored in the control substrate storage case. 9 (a) and 9 (b) show the comparison and illustration of the control board storage case 10 shown in FIG. 9 (a).
0A is obtained by increasing the degree of inclination of each of the control boards 121a to 121d inserted into the base housing 110a and increasing the degree of overlap between the control boards as viewed from the opening side of the base housing 110a. On the other hand, the control board storage case 100B of FIG. 9B reduces the inclination of each of the control boards 121a to 121d in the base case 110b,
Also, the degree of overlap between the control boards was not so close.

9A, the control board storage case 100A can be made thinner, and in the case of FIG. 9B, the control board storage case 100B itself becomes bulky. There is an advantage that the dimension in the direction can be slightly reduced (the width can be further reduced by reducing the interval between the control boards 121a to 121d).

The present invention is not limited to the above-described embodiment at all, and it goes without saying that various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the printed wiring circuit is provided on the inner wall surface of the control board storage case, but it may be a double-sided printed wiring having printed wiring circuits provided on both surfaces of the inner and outer walls. In addition, a single-sided printed wiring in which a printed wiring circuit is provided only on the outer wall surface is used. You may make it electrically connect.

The shape of the connection terminal provided on the control board side and the connection terminal provided on the control board storage case side;
The number, the mounting position, and the like are not particularly limited. In short, any connection terminal that can electrically connect the control board and the control board storage case side may be used. Moreover, in a specific example, the control board storage case side (base housing) is an example of the connection means.
Although the printed wiring is provided on the substrate, the present invention is not limited to this. For example, a lead wire, a connector, or the like may be used.
In short, any means capable of indirectly connecting the control boards is sufficient.

In the above embodiment, the support guide member for inserting the control board is provided in the base housing, and the control board is inserted along the guide groove of the support guide member. Even if no member is provided, a guide groove is formed on the lower wall surface of the base housing, and a slit-shaped exposed opening groove for exposing the wiring connector of each control board is formed on the upper wall surface. The configuration, method, position, and the like are not particularly limited.

The control board may be attached to the cover instead of the base casing, or may be attached to both the cover and the base casing. Further, the shape, position, and the like (for example, communicating with the control guide groove, providing the base housing, and the like) of the exposure opening that exposes a part of the control board (and eventually exposes the connector) are not limited. What is necessary is just to improve suitably.
