DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a slot machine, and more particularly, to a game machine provided for a game in a game arcade, for example, from alteration or alteration of the game machine. This makes it possible to take appropriate measures and measures that do not preserve them and can prevent them effectively.

[0002]

2. Description of the Related Art A gaming machine in a game arcade, for example, a slot machine or a pachinko machine in a slot machine hall or a pachinko hall, etc., is used for playing a game in a game arcade. It is a game machine installed in a game arcade for use in the game hall.

For example, in the case of a slot machine, for example, a player operates a rotating reel, and three reels are rotated simultaneously or individually and then stopped. This is a game machine for enjoying the success or failure of a required combination of pictures displayed on the reel at the time.

[0004] Specifically, after a special coin lent at a game arcade is inserted into a slot of a machine, the reels are rotated through operating tools such as levers for rotating three reels, and individual reels are rotated. The rotation is stopped through a means for stopping the rotation, and coins are obtained according to the combination of the reel patterns at the time of the stop. Usually, each reel is composed of, for example, seven types of patterns 21
There are (in some cases, 20) patterns, and several types of patterns that make up an effective combination are determined in advance, and the operation up to the stop of each reel while paying attention to those patterns is performed. This operation is performed by the player.

[0005] Most of such gaming machines installed in game arcades, such as slot machines, include the control of each mechanism, the winning probability (for a slot machine, the probability of establishing the above-mentioned effective combination), and the like. The whole control is performed under the control of the computer.

[0006] Therefore, in a gaming machine using a computer, a control circuit board (called a main board, hereinafter referred to as a main board, Computer board). Such a substrate
It is assumed that this is attached inside the gaming machine main body, and a gaming machine equipped with such a main board is shipped from a gaming machine manufacturer, delivered and installed in a gaming arcade, and provided with the above-described service in the gaming arcade. Served for

1 and a main board case F2).
The main board unit F cannot be removed unless the other internal mechanisms (such as the reel unit L) are attached to the machine main body T by attaching means P such as screws or disassembled. It is relatively easy to remove and attach without
The main board case F2 is a transparent plastic case, and the presence of a semiconductor device (CPU, ROM, etc.) inside the case is also visible from the outside.

However, such a situation is only as follows.
Such an act of unauthorized use of the control main board, for example, from the ideal use of a slot machine that aims to acquire more coins by originally exhibiting his own techniques such as “intuition” and “knack” of the player himself Deviates,
There is a possibility that the main board of the slot machine is taken out, and a change in the ROM or remodeling of the board is caused.

Desirably, it is possible to prevent or effectively prevent unauthorized or unlawful acts such as alteration or alteration of the main board. It is also desirable to be able to properly achieve this while meeting the above-mentioned regulations.

In order to eliminate such unauthorized use, the present invention has been improved and improved in view of the above points, and is intended to control a game machine installed in a game room for use by a player in a game room. It is an object of the present invention to provide a gaming machine which makes it possible to appropriately take countermeasures / measures which do not protect or effectively prevent illegal acts such as alteration or alteration of a main board for use.

In this case, in the slot machine 1 according to the present invention, FIG.
Unlike the above case, the one having the configuration shown in FIG.

In FIG. 3, reference numeral 50 denotes a base of the main body 1a (for example,
In the present embodiment, a main board case mounting table for mounting the main board case 60 in which the main board for control is arranged, which is provided inside the main body 1a. In the first state, a main board case mounting base 70 is provided, and the main board of the slot machine 1 is taken out, and an unauthorized use of the main board such as a ROM or a remodeling board is rejected. Storage of the main board case 60 in the main board case mounting table 70,
In the second state, a means (first means) for making the main board case 60 difficult to remove from the main board case mounting base 70 is provided. The table 70 is
It may be provided on the front panel 1b side.

Here, after the main board case 60 is stored in the main board case mount 70, it is locked with a key.
The main board case 60 cannot be taken out unless the key is opened.

0 In the preferred embodiment, the key box (key BO
X) 80, which is provided with a switchable lever (locking means; locking body) 81 (for example, a metal rod or the like) which can be rotated and locked by a key operation, for example, as shown by an arrow in the figure. Have. And in the unlocked state,
The lever 81 is in a first switching (rotational position, a sliding position when linearly sliding as described later) state in which the main substrate case 60 can be attached to and detached from (in and out of) the main substrate case mounting base 70. In the locked state, the lever 81 locks the main board case 60 in a state housed in the main board case mounting base 70 in a second switching (rotating position or sliding position) state, that is, a state as shown in FIG. To

Here, a key hole 82 is provided in the key box 80.
, A key can be inserted into this, and locking and unlocking can be directly performed by turning the key. Therefore, a key lock device having such a key operation can be used. In addition, the key is different from the case of opening and closing the front panel 1b of the slot machine 1 (in this case, for the maintenance of each slot machine during opening of a trouble, etc., a clerk targets many slot machines, It is necessary to open and close the front panel, and when requested by the player, it is necessary to respond promptly, so it is common to use a lock common to each slot machine for the same manufacturer and model.) , One for each slot machine 1 to which it applies
It is possible to adopt a mode in which different things are used on the table.

In this way, even if the front panel 1b is opened by a person who intends to commit wrongdoing, the main board cannot be taken out unless the key is opened as described above. The case 60 can be made difficult to take out.

It should be noted that one or more keys may be used, that is, the key lock device may be provided not only at one location but also at two or more locations, which may be implemented even more effectively.
In addition, such a key box 80 may be provided on the base 50 near the main board case mounting base 70, or may be provided so as to be fixed to the main board case mounting base 70 itself. Furthermore, the displacement of the lever 81 is not limited to the rotation,
A configuration (sliding type) that moves sideways to lock may be used (these points are the same in each example described later).

In the illustrated example, the main board case mounting base 70 has an upper surface 70a and a lower surface 70b, and a left side 70c and a right side so that four surrounding sides have two sets of opposing frame portions. While forming 70d, a partial front surface portion 71 is further provided on one side (right side in the figure) to form a bag-shaped portion 72. The remaining front side is open, and this is used as a detachable opening of the main board case 60 so that the main board case 60 can be taken out to the front side, that is, the front side in the direction intersecting the case surface. It can be configured so that it can be put in and out later (open arrows in the figure).

As shown in FIG. 4, one example of the main board case 60 is a transparent plastic case made of an upper case body 60a and a lower case body 60b (the upper case portion may be made transparent). In the bosses at the four corners, the upper case body 60a is
It is attached and fixed to the 0b body with screws 61 and closed. A main board 63 on which semiconductor devices 62a and 62b constituting the CPU 20, the ROM, and the like are mounted is mounted inside the case.
A connector portion 64 for connection is provided.

The main board case 60 has a short side surface 60m or 60n and a long side surface 60m.
In p or 60q, in the illustrated example, the seal 60t of the inspection certificate is attached to the upper case body 60a and the lower case body 60 at two places of the side surface 60m and the side 60q.
b, which serve as a seal.

In the present embodiment, the main board case 60 can be made into a cassette-like one as described above, and there is no need to provide a mounting bracket as shown in FIG. Just store it. As shown in FIG. 3, the main board case 60 can be put in and taken out of the frame of the main board case mounting base 70 from the front side in the direction of an arrow.
The main board case 60 in the housed state can be seen from the outside of the main board case mount 70, and the housed main board case 60 can be seen from the outside of the main board case mount 70 in the case. (This point is the same in each example described later), but in the second switching state in which the lever 81 is locked as shown, the front side of the main board case 60 in the housed state. (Upper case body 60a side) can be locked.
If the key is not unlocked, this can be reliably prevented.

Therefore, after assembling the main board case 60 into the slot machine main body 1a, it is locked with a key,
If the key is not opened, the main board case 60 cannot be taken out, and therefore the main board 63 cannot be taken out. Even if the main board of the slot machine is taken out, the ROM is changed or the board is remodeled, and the slot machine is to be returned to the main body again and the illegal use is attempted, the main machine is not changed. The substrate case 60 can be made difficult to take out, and it is possible to effectively cope with such squid prevention.

In the event that such an action is performed, it is difficult to determine such a change in the ROM in the case of FIG. 12, but if the key box 80 or the lever 81
If the main board case 60 is forcibly taken out, for example, by deforming, etc., in the present embodiment, it can be immediately found out by its traces. As a result, this point is also useful for preventing such rumbling, and this action can be suppressed beforehand. It is also an effective countermeasure against fraud and tort.

Further, according to the present invention, as shown in FIGS. 3 and 5, the main board case mounting base 70 is attached to the base 50 of the slot machine body 1a to be mounted, for example, by a stop screw 75 (screw fitting). ), The rear surface portion 73 is attached via the screw hole 73a, and the main board case mounting base fixing screw 75 is attached to the main board case 60.
Is stored in the main board case mounting base 70, the main board case 60 itself (and the main board 63) covers and is hidden (stowed). (This point,
The same applies to each example described later.) This will be more effective. In the case of FIG. 12, the exposed screw P or the like can be easily removed with a driver or the like. On the other hand, in the present embodiment, the main board case 60
Is not taken out of the main board case mounting base 70, the main board case mounting base fixing screw 75 itself cannot be removed. Therefore, even if it is attempted to take out the main board case 60 together with the main board case mounting base 70, it becomes more difficult to take out the main board case 60, and this can be more reliably prevented.

Such a configuration can be applied to the key box 50. In this example, the key box 50 is attached to a counterpart (the base 50 in the example of FIG. 3) to which the box is to be attached by a key box fixing screw 85 (screw attachment) in the box ( This is the same in an example described later.) Further, in a mode in which the key box 50 is fixed to the main board case mounting base 70 itself, for example, to the left side surface part 70c itself, a key box fixing screw is screwed from inside the left side surface part 70c. The function of the hidden screw (75) similar to that shown in FIG. 5 (the screw is stuck inside, so that it is difficult for the driver to enter) can be exhibited, and the embodiment may be implemented in this manner.

FIG. 6 shows a second embodiment of the present invention, which can be regarded as a modification of the above-described embodiment (first embodiment). The same or similar elements as those in the first embodiment are denoted by the same reference numerals (this point is the same in the examples described later). Hereinafter, the main part of the second embodiment will be described.

In this embodiment, the main board case mount 70
Is configured such that the main board case 60 can be slid in and out of the main board case 60 in the direction along the case surface (open arrows in the drawing). Therefore, front edge portions 71a, 71b connected to the front portion 71 of the bag-shaped portion 72 are provided on the upper surface portion 70a and the lower surface portion 70b of the main board case mounting base 70, respectively.
(Folded portion), and in the illustrated example, a portion corresponding to the left side surface portion 70c in FIG.
This is the opening of the main board case 60.

On the key box 80 side, the lever 8
In the second switching state (rotational position or sliding position) of the locked state, the side 1 is located on the side surface 60m side of the main board case 60 so as to rotate and lock (or move sideways to lock). So that the slide in and out can be prevented.

According to this embodiment, the same operation and effect as those of the first embodiment can be obtained. Main board 63 of slot machine 1
It is possible to make it difficult to take out the main board case 60 properly in order to prevent the change of the ROM and the remodeling of the board by taking out the main board case 60. After the main board case 60 is assembled,
If the key is locked and the key is not opened, the main board 63 cannot be taken out, so that it effectively functions to prevent such fuss.

In the above description, the key operation uses a key that is inserted into a key hole, and the lever is operated (movable) by turning the key by hand to lock and unlock the key. However, the present invention is not limited to this. Instead of such a key, for example, a method of electrically opening and closing with a magnetic card, a mark card, a punch card or the like may be used.

FIG. 7 shows an example of an electronic key lock device to which the present invention can be applied, and shows a configuration of a main part of a modification of the first and second embodiments. In the drawing, reference numeral 86 denotes a personal identification number key switch (card reader or key switch), 87 denotes an output unit, and 88 denotes an operating unit (movable unit), which can use, for example, a solenoid 88A. The present invention
A system that opens and closes with such a key lock device that can be electrically locked and unlocked may be used, and can be implemented in this way.

FIG. 8 shows a third embodiment of the present invention. This is an example of a method basically similar to that of the first embodiment with respect to the method of taking the main board case 60 in and out, the main board case mounting table 70, and the like. In this respect, a modification of the first embodiment. But also. Hereinafter, the main part of the third embodiment will be described.

In this embodiment, the main board case mount 7
As the reference numeral 0, a main board case mount 70 whose part is illustrated in FIG. 9 is used as an example, and a locking means (a locking body) for the main board case 60 is used as illustrated in FIG. ) Is used. As shown in FIGS.
