Description

  The present invention provides a control board on which a control circuit for controlling a game operation is formed, and a board case formed in a box shape divided into at least a base part and a lid part in order to accommodate the control board inside. And an IC tag sticker attached to the board case and provided with an IC tag on which information unique to the gaming machine is recorded.

Conventionally, a gaming machine of a slot machine has a gaming device necessary for playing a game, a control board on which a control circuit for controlling the operation of the gaming device is formed, and a power supply device that supplies power to the gaming device and the control board Etc. are provided.
Among these, the control board includes a ROM that stores a program for controlling a game operation, and a CPU that includes an LSI having a high-speed calculation function, and the CPU stores the program stored in the ROM.
Such a control board is a transparent synthetic resin board case formed in a box shape to prevent illegal acts such as replacing the genuine ROM with an unauthorized ROM storing an unauthorized program that is easy to win. It is stored inside.

The substrate case for storing the control board has a box shape with one side opened, and a base part on which the control board is installed, and a cover part that covers the upper side of the control board installed on the base part. What is provided is common.
And these base parts and a cover part are couple | bonded together in the closed state, in order to protect the control board installed in the inside from an unauthorized act.

The base part and the lid part are joined by a special coupler, for example, a so-called “crimping” provided with a pair of nested cylinders so that one can be inserted into the other. Is used.
That is, of the pair of “caulking” cylinders, a claw portion having a hook-shaped return portion is formed on the outer peripheral surface of the inner cylinder, and the aforementioned claw is formed on the inner peripheral surface of the outer cylinder. A step portion for locking the portion is formed. When one of the pair of cylinders is inserted into the other, one claw is locked to the other stepped portion, thereby preventing one from coming off inside the other, and the pair of cylinders mutually It is supposed to be combined.

  In the gaming machine as described above, when the closed board case is illegally opened, a seal seal is pasted over both the base part and the lid part so that it can be immediately recognized that the case has been opened. It has become. When the substrate case is opened, the sealing seal is broken, so that it can be seen that it has been opened.

  Here, it is possible to deceive that the substrate case has been opened improperly by applying a sealed seal seal instead of the broken seal seal. In recent years, as a measure against this sealed seal of articles, an IC tag seal integrated with an IC tag in which unique information such as a serial number is electronically recorded is adopted as a seal seal, and this IC tag seal is affixed to a substrate case. Has been implemented.

If such an IC tag seal is adopted, reading of recorded contents and supply of driving power can be performed simultaneously by wireless communication by using a dedicated reader, so whether or not the attached seal sticker is genuine. Such a determination can be made easily and quickly.
Further, when the IC tag seal integrated with the IC tag is peeled off, the IC tag seal can be formed so that the wireless antenna of the IC tag is destroyed. If such an IC tag seal is used, the appearance is not damaged. Even if the IC tag seal can be peeled off from the substrate case, the wireless antenna of the IC tag is destroyed and the recorded content of the IC tag cannot be read, so it is easy to determine whether the substrate case has been opened illegally and Can be done quickly.

  However, even if the above-mentioned IC tag seal is used, if the IC tag seal is carefully peeled off from the substrate case using a sharp blade, for example, a razor, no damage will be caused to the wireless antenna or the appearance of the IC tag. The IC tag seal can be peeled off from the substrate case, which allows reuse of the peeled IC tag seal. Whether the substrate case is opened by re-applying the IC tag seal after opening the substrate case There is a problem that it is difficult to discriminate between them.

  In order to solve this problem, a base sheet provided with an IC tag chip, an adhesive layer made of an adhesive for adhering the base sheet to a substrate case, and between the base sheet and the adhesive layer A wireless antenna formed by etching a metal layer formed on the adhesive layer and an adhesive layer that is formed and bonds the base sheet and the adhesive layer to each other with an adhesive strength weaker than the adhesive strength of the adhesive layer And an IC tag seal in which the base sheet is broken with a force smaller than the adhesive force of the adhesive layer has been proposed (see, for example, Patent Document 1).

According to such an IC tag seal, even if the IC tag seal peeling process is carefully performed using a razor or the like, in order to peel the IC tag seal from the substrate case, the peeling force against the sticking force of the sticking layer is provided. When added to the IC tag seal, the base sheet is broken by this peeling force, and the appearance of the IC tag seal is impaired.
In addition, the peel strength against the sticking force of the sticking layer peels the adhesive layer from the base sheet and electrically separates the wireless antenna formed on the sticking layer from the IC tag formed on the base sheet. Therefore, it becomes impossible to read the recorded contents of the IC tag.
For this reason, even when the IC tag seal is peeled off using a razor or the like, the IC tag seal cannot be reused, and it is possible to effectively determine whether or not the substrate case has been opened.

JP 2009-50537 A

  In gaming machines such as those described above, if the adhesive force of the adhesive layer can be neutralized with chemicals, no force is applied to the IC tag seal when the IC tag seal is peeled off from the substrate case. Since the IC tag seal can be peeled off from the board case without causing any damage to the appearance, the peeled IC tag seal can be reused, and there is a risk that it will not be possible to reliably prevent fraudulent acts such as replacing it with an illegal ROM. is there. Therefore, there is a demand for a gaming machine in which the IC tag seal is reliably broken by opening the substrate case.

In this case, the cover member 60 functions as a detachable cover that covers the IC tag seal 12 without damaging the IC tag seal 12 when being removed from the substrate case 50.

Then, after removing the substrate case 50 to the housing 2, the substrate case 50 can be opened by pulling the cover member 60 out of the sandwiched portions 54 and 55.
At this time, when the cover member 60 starts to move in the direction of being pulled out from the sandwiched portions 54 and 55, the blade portion 72 of the breaking member 70 breaks in conjunction with the cover member 60 as shown in FIG. The movement starts from the start position α, the blade edge of the blade portion 72 tears the IC tag seal 12 attached to the tag attaching surfaces 56A and 56B, and the wireless antenna connected to the IC tag chip is cut and destroyed.

(Effect of embodiment)
According to this embodiment as described above, the following effects can be obtained.
That is, a pair of sandwiched portions 54 and 55 are provided in mutually corresponding portions of the base portion 52 and the lid portion 53 that form the substrate case 50, and when these sandwiched portions 54 and 55 are combined with each other, a box shape And tag attachment surfaces 56A and 56B that straddle both of the sandwiched portions 54 and 55, and the IC tag seal 12 is attached to the tag attachment surfaces 56A and 56B. Since the cover member 60 having a pair of arm portions 61A, 61B formed in a plate shape that covers the entire surface of the sandwiched portions 54, 55 is provided while sandwiching the portions 54, 55 from both sides, the sandwiched portion 54, If the IC tag seal 12 is affixed to the tag affixing surfaces 56A and 56B provided in 55 and the cover member 60 is attached to the substrate case 50 in this state, the IC tag seal 12 is sealed inside the cover member 60, and the IC tag seal 12 is attached. Razor when removing from the substrate case 50 Therefore, it is impossible to use the blade of the IC tag seal 12 and chemicals cannot be applied to the IC tag seal 12. Therefore, the IC chip seal, the wireless antenna and the appearance of the IC tag seal 12 are not damaged and the IC is removed from the substrate case 50. It becomes impossible to peel off the tag seal 12.
In addition, since the pair of sandwiched portions 54 and 55 provided on the base portion 52 and the lid portion 53 are sandwiched between the pair of arm portions 61A and 61B of the cover member 60, the arm portions 61A and 61B of the cover member 60 are provided. If the cover member 60 is placed in a closed position that sandwiches the pair of sandwiched portions 54 and 55, the substrate case 50 cannot be opened, and the cover member 60 must be pulled out of the closed position to open the substrate case 50. There is.

Here, the cover member 60 is pushed toward the sandwiched portions 54 and 55 and disposed at the closed position of the substrate case 50. In this state, the blade portion of the breaking member 70 is inserted into the blade insertion hole 60A provided in the cover member 60. When 72 is inserted, the blade portion 72 is set at the break start position α without damaging the IC tag seal 12.
Thereafter, when the cover member 60 is pulled out from the closed position in order to open the substrate case 50, the blade portion 72 of the breaking member 70 moves along the slits 58A and 58B as the cover member 60 is pulled out. With the moving blade portion 72, the IC tag seal 12 affixed to the tag affixing surfaces 56A and 56B can be reliably broken.
For this reason, when the substrate case 50 is opened, the IC tag seal 12 is surely broken, and the reuse of the peeled IC tag seal 12 can be reliably prevented.

Further, of the caulking member 81 and the caulking receiving portion 82 that couple the base portion 52 and the lid portion 53 to each other, the caulking member 81 is protected by covering the back surface and side surfaces of the base portion 81A with a metal protective cover member 83. The lid 53 is protected by covering the side with a metal protection plate 85. Therefore, when replacing the ROM etc. provided in the substrate case 50 with an unauthorized one, Even if an attempt is made to destroy the caulking member 81 and the caulking receiving portion 82 from the side surface or the back surface of the substrate case 50 using a drilling tool such as the above, the metal protective cover member 83 and the protective plate 85 block the caulking member 81. In addition, it is possible to prevent the caulking receiving portion 82 from being destroyed, and thus to prevent unauthorized exchange of the ROM or the like.
It is rare that the inner caulking member 81 and the caulking receiving portion 82 are destroyed from the front surface of the substrate case 50. This is because when the inner caulking member 81 and the caulking receiving portion 82 are destroyed from the front of the substrate case 50, the traces of destruction formed on the front surface of the substrate case 50 are conspicuous, and the front door 3 of the slot machine 1 is opened. This is because cheating is discovered.

  Further, when the notch portions 83D and 83E are formed in the side walls 83B and 83C of the protective cover member 83, and the caulking member 81 is attached to the base portion 52 in a state where the protective cover member 83 is attached to the back portion, the side walls 83B and 83C Since the notches 83D and 83E formed in the 83C are locked to the flanges 84C formed on both sides of the opening 84B, the side wall of the base 52 facing the back surface of the caulking member 81 is improperly used. Even if the hole corresponding to the size of the back surface of the protective cover member 83 is opened, the cutout portions 83D and 83E of the side walls 83B and 83C are locked to the flange portions 84C on both sides of the opening 84B, and the protective cover member 83 cannot be removed. Therefore, even if a hole is formed in the back surface of the protective cover member 83 in order to destroy the caulking member 81 and the caulking receiving portion 82, the protective cover member 83 cannot be removed, whereby the caulking member 81 and the caulking receiving portion 82 can be prevented from being destroyed, and as a result, illegal exchange of ROM or the like can be prevented.
