DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine, and more particularly, to a board storage mounted in a state in which a control board for controlling a game is stored on the back of a game board of a gaming machine such as a pachinko gaming machine or a throttle machine. The present invention relates to a mechanism provided with a box, which is provided with a countermeasure for preventing fraudulent opening of the board storage box.

[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 204, the pressing pin 2 previously inserted and locked into the cover-side sealing portion 203a 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 pressing 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 pressing pin 205 is pushed. If you destroy the part, the trace will surely remain.
As a result, an act of unauthorized opening can be found, so that the wrongful act by the wrongdoer is suppressed and prevented.

Further, a plurality of sealing portions 201 having a pressing pin 205 as the sealing means and a connecting portion 203b as the unsealing means are provided at a plurality of locations, for example, four locations on the left and right side surfaces of the substrate storage box 200, respectively. If the sealing portion 201 at the diagonal position viewed from the cover 203 side is sealed by pressing the pressing pins of the sealing portion at a total of two locations, one each for the left and right sides, sealing and unsealing are performed four times. be able to. 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, as in the structure of the substrate storage box 200 shown in FIGS. 9 and 10, the distal end portion 205a of the pressing pin 205 is connected to the sealing portion 201.
Fixing plate 2 fixed inside case-side sealing portion 204a
It is not impossible to remove even if it is fixed so that it cannot be pulled out by pushing it into the fitting hole 206a of No. 06. For example, by using a special tool, or by applying inconspicuous processing to the sealed portion of the box, the pressing pin 205 may be forcibly pulled out without breaking the sealed portion, the box, and other portions. In this way, after the pressing pin 205 is removed and the ROM provided on the control board 82 is exchanged for a so-called back ROM, or the like, unauthorized modification is performed, the pressing pin 205 is re-opened as if it were in a sealed state. If stored, there was a problem that the act of unauthorized opening was hardly discovered.

SUMMARY OF THE INVENTION An object of the present invention is to make it difficult to open a substrate storage box for storing a control substrate provided on the back surface of a game machine main body or the back surface of a game board without leaving a trace.

The procedure for sealing the inside is similarly described with reference to FIG.

FIG. 8A shows the substrate storage box 9 before sealing.
0 shows the state of the cross section of the sealing portion 110, and the tip 111a of the pressing pin 111 previously mounted on the pressing pin mounting base 115 of the cover body 92 is fixed to the fixing base 1 of the case body 91.
12 is located above a fitting hole 113a formed in the pressing pin fixing plate 113 housed and fixed in the pressing pin 12.

In this state, using a tool such as a screwdriver, the pressing pin 1 is pressed by pressing the upper surface of the head 111e of the pressing pin 111 from above.
11 penetrates further down from the fitting hole 113a of the pressing pin fixing plate 113, and the leading end of a fitting piece 113b formed in the groove 111b and inclined downward at the inner peripheral edge of the fitting hole 113a fits. At the same time, the tip 111a of the pressing pin 111 abuts on the upper wall 141a of the fixing chamber 141 further below the fitting hole 113a to break the upper wall 141a, and is immersed in the adhesive 135.

When the upper wall 141a is destroyed, the adhesive 1
Since 35 is exposed to the outside air, it hardens in a state where the tip 111a of the pressing pin 111 is immersed in the fixing chamber 141 (FIG. 8).
(B)). Accordingly, the tip 111 a of the pressing pin 111 is integrally fixed to the fixing table 112 in the fixing chamber 141 by the cured adhesive 135.

Furthermore, the groove 111b of the pressing pin 111 is also fitted and fixed in the fitting hole 113a of the pressing pin fixing plate 113, so that the pressing pin 111 is fixed to the fixing base 112 doubly. Further, since the pressing pin 111 operated for sealing has its flange-shaped head 111 e restricted from moving downward from the bottom surface of the pin head housing chamber 115 a of the pressing pin mounting base 115, the cover is not covered. The main control board 82 is sealed in the board storage box 90 because the press pin mounting base 115 of the body 92 and the fixing base 112 of the case body 91 are integrally connected by the press pins 111. Also in this case, the pressing pin fixing plate 113 is
Needless to say, the main control board 82 can be sealed in the board storage box 90 even if it is not provided on the board storage box 90.

In order to open the substrate storage box 90 according to the above-described two embodiments, the connecting portion 118 connecting the pressing pin mounting table 115 and the cover body 92 at the portions used for sealing is used. It can be easily opened by cutting with a tool such as a nipper. It is also possible to open the package by other methods, for example, by forcibly pulling out or breaking the pressing pin 111 fitted to the pressing pin fixing plate 113, in which case the pressing pin can be opened without breaking the pressing pin mounting base 115. It is very difficult to extract 111, and even if the pressing pin 111 is extracted without breaking other members, traces of the extracted pin are clearly left by the adhesive 135 hardened in the fixing chamber. In other words, if the pressing pin 111 is extracted from the adhesive 135 that has been hardened integrally with the tip 111a, an unnatural portion is surely formed, and it is extremely difficult to erase the trace.

Further, the pressing pin fixing plate 113 is
It is possible to open the cover by removing the tapping screws 106 and 106 that fix the pressing pin fixing plate 113 to the fixing base 112.
It is very difficult to remove the pressing pin fixing plate 113 without destroying it because the screw hidden pieces 117, 117 provided in the above are obstructive. Even if the pressing pin fixing plate is skillfully removed, Since the tip 111a of the pressing pin 111 is integrally fixed in the fixing chamber of the fixing base 112 by the adhesive 135, the trace of the adhesive 135 hardened in the fixing chamber is also obtained in this case.
Clearly remain.

That is, even if the pressing pin 111 used for sealing in such a configuration is skillfully withdrawn without destroying other members or parts, the trace of the removal is surely left by the adhesive, Moreover, it is almost impossible to repair it so that no trace can be seen at a glance.

Further, if at least the fixing base 112 is formed of a transparent resin material or the like, the adhesive 13 in the fixing chamber is formed.
Since the state of No. 5 can be visually recognized from the outside, the pressing pin 1
If 11 is taken out, the trace becomes clear. That is, it is possible to easily determine whether or not the substrate storage box 90 has been opened by checking only the state of the cured adhesive 135 (unnatural shape or the like) in the fixing chamber. Easy to find cases.

In this way, if the information is illegally opened to perform the illegal operation on the main control board 82 for controlling the contents of the gaming machine, it can be detected at an early stage, and the trace of the illegally opened operation can be erased. It ’s extremely difficult,
Such fraudulent acts by fraudsters will be suppressed.

The above-mentioned 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”. Tapping the pressing pin 111 at the portion marked with “” seals it. 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 can be performed by hitting the pressing pins 111 of the portions to which the left and right numbers “2” are attached. Since the main control board 82 housed in this manner can be opened and sealed a plurality of times for regular reasons such as ROM inspection and repair, the maintenance property 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, in the above-described structure for restricting the movement of the pressing pin in the sealing direction in the pressing pin mounting table, the flange-shaped head of the pressing pin and the pin head storage chamber of the pressing pin mounting table cause downward movement. Although the structure in which the movement is restricted is shown, the structure is not limited as in the above-described embodiment. In short, the movement of the cover body in the opening direction is surely restricted by the pressing pin used for sealing (that is, Any structure can be used as long as the structure cannot be opened.

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.

[0064]

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.
