DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine, and more particularly, to a game machine such as a pachinko game machine or a throttle machine. The present invention relates to a gaming machine provided with a board storage box in which a prohibited fraud prevention measure is taken.

[0002]

2. Description of the Related Art In recent years, the mainstream of gaming machines such as pachinko gaming machines and throttle machines have been to control various prize devices and symbol variation display devices provided on the gaming board to excite the interest of the game. The control of the prize winning device and the symbol variation device is performed by a logic-controlled circuit board on which a number of electronic components such as ICs and LSIs are provided, or a control board including a microcomputer. A control board for controlling the game content of such a gaming machine is generally stored in a board storage box attached to the back side of the game board.

[0003] The board storage box is made of resin or metal. A control board or the like on which various electronic components such as ICs and resistors are mounted is housed in the box, and a printed circuit on the board is short-circuited. In order to prevent this, dust and other dust are protected from intrusion and are mainly attached to a mechanism plate or the like on the back of the gaming machine. For example, in the accessory control device, a CPU, a ROM, a RAM, and the like are provided in a control circuit,
The gaming machine is controlled in accordance with a control program stored in the ROM, and a jackpot or the like is also controlled here.

A board storage box for housing such a control board has a box structure in which a cover body and a case body are overlapped, and a connector portion of the control board electrically connected to other various electric devices is provided. It is provided so as to be exposed from the box. By inserting various wires into the connector section, it is possible to control each of the electric devices.

[0005] An illegal act on the board storage box for housing the control board is to remove the cover body serving as the upper lid,
By replacing electronic components such as ROM provided on the opened control board or rewriting data contents, illegal game control such as frequent jackpots can be performed as compared with normal game control. It's like having it done.

A conventional structure for sealing a control board in a board storage box is such that once the seal is opened, a cover body and a case body are screwed together so that a trace of the opening remains. After that, a sealing seal is put on the joint between them, and the board storage box is made of a transparent synthetic resin material such as acrylic so that the state of the control board housed inside can be visually recognized from the outside. Although the act was confirmed, it is not effective for fraudsters who use a genuine seal seal or special release agent.

[0007] In order to prevent such misconduct, it is conceivable to make the substrate storage box impossible to open or extremely difficult to open so that there is no other way but to destroy the box itself. It is not realistic considering maintainability such as ROM inspection and repair by a public organization. Therefore, as a countermeasure against these problems, a substrate storage box having a sealing structure as shown in FIGS. 9 and 10 has been proposed. FIG. 9 is a top view of the substrate storage box 200, and FIG. 10 is a cross-sectional view taken along the line AA of the sealing portion 201 provided on the side surface of the substrate storage box 200.

As shown in the figure, the board storage box 200 has four sealing portions 201 on each of the left and right sides (only three on one side are shown), and a resin case housing and fixing the control board 202. After covering the same resin cover 203 from above the sealing member 204, the sealing pin 2 previously inserted and locked into the cover-side sealing portion 203 a of the sealing portion 201 is locked.
05 into the fitting hole 2 of the fixing plate 206 fixed inside the case-side sealing portion 204a of the sealing portion 201.
06a, it is fixed so that it cannot be pulled out. Thus, the cover-side sealing portion 203a and the case-side sealing portion 204a
Is fastened by the sealing pin 205 so that the control board 2
02 is sealed in the substrate storage box 200.

In this case, the cover 203 is attached to the case 20.
In order to open the substrate box 200 by detaching it from the cover 4, the severable connecting portion 203 b connecting the side wall of the cover body 203 and the cover-side sealing portion 203 a is cut with a nipper or the like. It can be easily opened. In other words, the connecting portion 203b cannot be opened except by cutting the connecting portion 203b or breaking the sealing portion 201 or the box itself into which the sealing pin 205 is pressed. Destruction of other parts will surely leave traces.
As a result, an act of unauthorized opening can be found, so that the wrongful act by the wrongdoer is suppressed and prevented.

A plurality of sealing portions 201 having a sealing pin 205 as a sealing means and a connecting portion 203b as an unsealing means, for example, four at the left and right sides of the substrate storage box 200 are provided. If the sealing portion 201 at a diagonal position viewed from the cover 203 side is sealed by pushing the sealing pins of the sealing portion at two locations, one each at the left and right sides, sealing and unsealing four times It can be performed. Therefore, at the time of opening the ROM provided on the control board for a valid reason such as inspection or repair, the connecting portion 2 of the sealed portion is not opened.
03b can be opened simply by cutting, so every time the box is opened, it must be replaced with a new box, as in the case of adopting a structure that cannot be opened unless the box itself is destroyed. Thus, the opening and sealing operations can be performed a plurality of times, and the maintainability such as the ROM inspection of the control board is also good.

[0011]

However, even with a structure such as the substrate storage box 200 shown in FIGS. 9 and 10, the connecting portion 203b is cut well so that it can be repaired, and is provided on the control substrate 82. After performing unauthorized modification such as replacing the ROM with a so-called back ROM, the connecting part 203b may be cleverly restored and the trace of the cut may become inconspicuous. There has been a problem that the act of opening a fraudulently is not discovered or delayed.

In other words, the outer diameter of the connecting portion is limited to some extent in order to enable easy cutting with good workability by using a nipper or the like. In this case, the box cannot be easily cut, and the opening workability is deteriorated. In addition, if the opening is formed thick, the stress at the time of cutting is large and the box itself may be broken. Therefore, in such a connecting portion that needs to be formed to be thin or thin so that it can be easily cut with a nipper or the like, there is a high possibility that the connecting portion will be repaired to an inconspicuous degree.

The problem to be solved by the present invention is to make it difficult to restore the substrate storage box provided on the back of the game machine main body and the control board provided on the back of the game board so as to erase the trace of opening the board storage box. It is to prevent fraudulent acts against a gaming machine.

[0014]

According to a first aspect of the present invention, there is provided a gaming machine, comprising: a case body accommodating a control board for controlling a game;
In a gaming machine provided with a substrate storage box including a cover body attached to the case body, the case body and the cover body are provided with sealing portions that are fastened to each other in a sealed state, At least one sealing portion of the cover-side sealing portion and the case-side sealing portion is connected via a severable connecting portion, and a cavity is formed in a cutting region of the connecting portion,
The gist is that a liquid is sealed in the cavity so as to be leaked by cutting.

The case body and the cover body of the substrate storage box having the above structure are provided with a sealing portion which is fastened in a sealed state to each other, and at least one of the cover side sealing portion and the case side sealing portion. Since the seals are connected via a severable connection, the box can be easily opened only by cutting the severable connection to open it without breaking the box itself and the seals. In addition to the above structure, a liquid is sealed in a cavity formed in a severable region of the connection portion to be cut so as to be leaked by cutting.

In order to easily open the substrate storage box assembled and sealed once without breaking the box itself or the portion where the sealing portions are fastened, the connecting portion is cut. Not only is there a way to open it, but also the liquid is sealed in the cavity formed in the cut portion so that it can be leaked by cutting. When the liquid leaks out, a trace of a reliable cut due to a change in the state of the liquid in the cavity, for example, the presence or absence of the liquid or adhesion to the substrate storage box or the like remains.

That is, it is possible to easily determine whether or not the substrate storage box has been opened simply by checking whether or not there is a change in the state of sealing the liquid in the cavity formed in the connection portion that is cut at the time of opening. This makes it easier to detect unauthorized opening. In addition, in order to restore the cut connection portion to its original state, the same liquid as the sealed liquid must be sealed again in the cavity in a liquid-tight state, so that restoration is almost impossible. In this way, when an illegal act on a gaming machine is performed, it is found early and the trace of the illegal act cannot be erased, so that the act of unauthorized opening by such an illegal actor can be suppressed. .

In this case, as described in claim 2, if the sealed liquid is a colored liquid that is visible, traces of cutting due to the presence or absence of the liquid and adhesion of the leaked liquid to the substrate storage box are generated. Since it is easy to visually recognize, it can be more easily determined whether or not the substrate storage box has been illegally opened.

Further, as described in claim 3, since the state of the liquid sealed in the cavity can be visually recognized from the outside, the state of the liquid, for example, the presence or absence of the liquid or the discoloration, may cause the liquid to be illegally acted. The trace of whether the connection has been destroyed becomes clearer. It is easy to check the state of the liquid by making the state of the liquid sealed in this way visible from the outside, for example, by forming the connecting portion with a transparent material or the like so that the liquid in the cavity can be seen through. Therefore, it is possible to easily determine whether or not the wrongdoing has been performed.

In this case, as described in claim 4, the case-side sealing portion and the cover-side sealing portion are each formed with a plurality of fastening portions corresponding to each other, and are provided in the cavity of each connecting portion. If the liquid is sealed, the substrate storage box can be opened and sealed a plurality of times. Therefore, even if the control board is opened for a legitimate reason such as ROM inspection or repair by a public organization, the control board can be resealed, and the maintainability is improved.

Further, when the cutting region of the connecting portion to be cut is formed of a transparent resin material, the liquid sealed in the cavity can be visually recognized from the outside and the cutting can be performed. Not only is it easier, but also it is extremely difficult to repair the illegal act of sealing the liquid in the cavity again in a liquid-tight manner.

Further, as described in claim 6, the member having at least the connecting portion between the case body and the cover body is formed by integrally molding the main body portion, the connecting portion connected thereto and the sealing portion with a transparent resin material. With this configuration, in addition to the above-described functions and effects, the manufacturing is easy and the cost is low, and the state of the accommodated control board can be visually recognized from the outside.

In this case, the sealing pin mounting base 115 is broken. It is very difficult to remove the sealing pin 111 without
The sealing pin fixing plate 113 can be opened by removing the sealing pin fixing plate 113 from the fixing base 112.
Since the screw concealing pieces 117 and 117 provided on the cover body 92 hinder removal of the sealing pins 6 and 106, it is also very difficult to remove the sealing pin fixing plate 113 without breaking them. In other words, there is no other way to remove the sealing pin 111 or the sealing pin fixing plate 113 except for destroying other members and parts, and if it is destroyed, the traces are surely left, and at a glance Then it is almost impossible to repair it so that its traces cannot be seen.

Therefore, a person who intends to open the substrate storage box 90 in order to perform such misconduct cuts the connecting portion 118 which is relatively easy to repair even if it is broken, and is cut at first glance. It is conceivable that the trace may be made inconspicuous and the trace may be inconspicuous. However, as described above, the liquid 119 is contained in the liquid enclosing chamber 118a formed inside the connecting portion 118. The liquid sealing chamber 118a is sealed while maintaining the tight state.
The liquid enclosing chamber 118a is formed over the entirety of the connecting portion 118 so that the connecting portion 118 cannot be cut without destroying the liquid, so that if the cutting is performed, the liquid 119 sealed inside leaks out to the outside without fail. Scattered into the outside air, and a trace of the cutting by the connecting portion 118 in a state where the liquid has disappeared clearly remains. Connecting part 11 cut to eliminate this trace
8 to restore it to its original state,
Must be sealed again, and the cut portion must be sealed so that the liquid 119 does not leak out.
Restoration is extremely difficult and will surely leave traces.

Further, if only the state of the liquid 119 sealed in the liquid sealing chamber 118a is confirmed, it can be easily determined that the base end storage box has been opened. In this case, if the state of the sealed liquid 119 is configured to be visible from the outside, it becomes easier to check the presence or absence of the liquid 119, and further, if the liquid 119 is a colored liquid, the trace is more remarkable. It becomes clear. That is, the connecting portion 118
By checking the change in the state of the liquid 119 (the presence or absence of liquid, discoloration, etc.), it is possible to easily determine whether or not the substrate storage box 90 has been opened. Easy to do.

In this way, if an unauthorized opening is performed in order to perform an illegal act on the main control board 82 for controlling the contents of the gaming machine, the unauthorized opening can be detected at an early stage, and the trace of the unauthorized opening can be erased. Since it is extremely difficult, such fraudulent acts by fraudulent persons will be suppressed.

The above-described sealing of the substrate storage box 90
The opening can be performed four times. As shown in FIG. 4, numbers are displayed diagonally (in this case, 1 to 4) on the left and right sides of the upper surface of the cover body 92. For example, when sealing is performed for the first time, the left and right numbers are “1”. The sealing pin 111 at the portion marked with “” is beaten to fit into the fitting hole 113 a of the fixing plate 113 and sealed. When inspecting the ROM or the like of the main control board 82, it can be opened by cutting the connecting portion 118 of the portion with the number “1” on the left and right. Then, in order to seal again, the sealing pin 111 in the portion to which the number “2” on the left and right is attached is beaten to seal. ROM of main control board 82 housed in this way
Since opening / sealing can be performed a plurality of times for regular reasons such as inspection and repair, maintenance is good. Needless to say, in this case, it is necessary to separately record and manage the history such as the number of times of opening / sealing. Unauthorized opens that do not match the history can be found.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the spirit of the present invention. For example, the liquid sealed in the connecting portion is described using a colored ink or the like in the above embodiment, but in addition to this, a liquid or the like that changes color or discolors when exposed to an adhesive or oxygen is used. However, the present invention is not limited to this. It is desirable to ensure that traces of these liquids leaked at the time of cutting the connecting portion adhere to the substrate storage box and are opened,
If it is possible to confirm that the substrate storage box has been opened due to changes in the state of the liquid in the liquid filling chamber (the presence or absence of liquid, the characteristics of the liquid, the amount of liquid), etc., even if such traces do not remain. good.

Further, the sealing structure of the substrate storage box is not limited as in the above-described embodiment. In short, the substrate storage box assembled once destroys the box itself and the closed sealing portion. Needless to say, any structure that can be easily opened only by cutting the connecting portion for opening so as not to be able to open the package without opening is required.

In the above-described embodiment, an example is shown in which the present invention is applied to the board storage box of the main control board which is the main control board for controlling the game content of the gaming machine. It is needless to say that the present invention can be applied to a box for storing a board or the like.

[0061]

According to the gaming machine of the present invention, it is impossible to take out the control board unless the board storage box is partially broken, and it is impossible to cheat without leaving a trace. In addition, it is very difficult to restore the traces and erase them. As a result, it is possible to prevent improper activities against the gaming machine beforehand, which can further contribute to the development of a sound gaming industry.
