DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate case sealing device used for a ball-and-ball game machine such as a pachinko machine and an arrangement ball machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a control board on which a ROM and other electronic parts are mounted is mounted in a board case which is openable and closable by a first case body and a second case body. An electronic control system is employed in which the board case is stored and mounted on a back cover or the like on the back side of the game board, and the game operation is controlled by electronic components such as a ROM on the control board side. In this type of ball game machine, the R mounted on the control board
At the same time, it is necessary to prevent unauthorized replacement of electronic components such as the OM, and at the time of inspection by an inspection agency such as a regulatory agency, it is necessary to open the substrate case to allow easy inspection. Therefore, conventionally, a seal sticking portion for a sealing seal is provided on the board case, and after the control board is stored in the board case, a sealing sticker is stuck to the sticking portion of the board case to seal. In this case, if there is any unauthorized modification such as breaking the seal seal and opening the board case and replacing the ROM, the fact can be easily recognized by the breakage of the seal seal, and at the time of inspection by the inspection organization, the seal seal must be replaced. The substrate case can be easily opened by breaking, and after the inspection, the sealing case can be easily sealed by attaching a sealing seal again to the seal attaching portion.

[0003]

The conventional sealing method using a sealing seal has a drawback that illegal alteration such as opening the board case and replacing the ROM cannot be reliably prevented. That is,
In the conventional sealing method using a sealing seal, a sealing seal with an adhesive is used, and this sealing seal is attached to the seal sticking portion, so if a special solvent that reduces the adhesive force of the adhesive is used, traces are not obtained. The seal can be peeled off relatively easily without leaving the seal, and the seal can be attached again to the seal attaching portion.

[0004] For this reason, it is not possible to prevent improper remodeling in which the board case is opened to replace the ROM or the like beforehand, and even if improper remodeling is performed, no trace is left on the sealing seal. Simply checking the board case from the outside does not make it easy to discover the fact, which encourages unauthorized modification. In view of such conventional problems, the present invention makes it impossible to open the board case unless the cutting portion is cut, and when the board case is opened by inspection, the fact of opening is easily recognized by the trace remaining on the board case side. It is an object of the present invention to provide a board case sealing device for a ball-and-ball game machine which can confirm and can easily seal the substrate case even when resealing after opening, and can prevent unauthorized modification by opening the substrate case. I do.

After setting the case lid 16, the substrate case 6 is sealed by the sealing device 19. When sealing is performed first, the sealing pin 37 corresponding to the number “1” is pressed toward the pin fitting portion 32 by a driver or the like. That is, the sealing pin 37
When the tip of a driver or the like is brought into contact with the engaging head 44 side of the sealing pin 37 and the sealing pin 37 is pressed in this state, the pressing force
Is destructively broken, and the engagement head 44 is separated from the annular portion 47. Since the breaking portion 49 is thin, it can be easily broken. When the engaging head 44 side is further pressed after the rupture portion 49 is broken, the engaging head 44 is pushed into the pin holding portion 33, and the engaging head 44 is completely inserted into the pin holding portion 33. In the state of being buried, it comes into contact with and engages with the engaging step portion 43 of the pin holding portion 33. on the other hand,
After the pair of legs 45 of the sealing pin 37 are elastically deformed inward and the engaging portions of the respective legs 45 pass through the pin locking portions 35 in the pin fitting portions 32, the engaging portions are The engagement part 35 is irremovably engaged from the opposite side. By pushing the two sealing pins 37 corresponding to the numeral "1" into the pin holding portion 33, the board case 6 can be sealed with the two sealing pins 37 spaced apart. , So that the substrate case 6
Is completed. Note that, when the breaking portion 49 is broken, the annular portion 47 remains in a fitted state on the pin holding portion 33 side, but this may be removed as appropriate.

When the inspection of the ROM or the like of the control board 7 is performed after the ball-and-ball game machine is installed in a hall or the like, "1" is set.
The cutting section 34 on the pin holding section 33 side holding the two sealing pins 37 in the sealed state corresponding to the numbers of above is cut and broken by a tool such as a nipper. When the cut section 34 is cut, the cut pin holding section 33 is separated from the case lid 16 and the sealing pin 37 is cut.
Therefore, the sealing of the board case 6 by the two sealing pins 37 can be released. Therefore, the control board 7 or the ROM or the like can be taken out by opening the board case 6 and easily inspected. When resealing after the inspection on the control board 7 side, the sealing pins 37 temporarily fixed to the two pin holding sections 33 corresponding to the number “2” are inserted from the pin holding section 33 side into the pin fitting sections. The board case 6 is sealed by the two sealing pins 37 by pushing it into the side 32. Therefore, the board case 6 can be easily resealed after the inspection.
After the inspection, the inspection history is written on an inspection history sticker attached to the seal attachment portion 51 of the case body 15.

Opening and resealing by inspection can be performed up to three times for one substrate case 6, and in any case, the cut section 34 on the sealing side is cut off and temporarily fixed to the adjacent side. In this case, the sealing pin 37 may be pushed in to reseal. In this embodiment, the engaging head 44 of the sealing pin 37 in the sealed state is completely immersed in the pin holding portion 33, and the engaging portion on the tip side is in the bottomed pin fitting portion 32. Since it is elastically engaged with the pin locking portion 35, once it is once sealed with the sealing pin 37, it is very difficult to remove the sealing pin 37 from the outside and release the sealed state. Yes, the sealing of the substrate case 6 cannot be released unless the cutting portion 34 is cut and broken by a tool or the like.
Also, if the cut portion 34 is broken and the substrate case 6 is opened, a trace of the break of the cut portion 34 remains on the case lid 16 side,
A pin holding part by a sealing pin 37 on the support side of the case bottom plate 14

Unauthorized modification such as opening the board case 6 and illegally replacing the ROM on the control board 7 becomes difficult, thereby preventing unauthorized modification.

In particular, traces of opening remain on the substrate case 6 side,
Since it is extremely difficult to completely hide the traces, an effect of psychological restraint on a fraudulently modified person can be expected, and it is possible to prevent rampant modification from occurring. Moreover, by comparing the trace on the substrate case 6 with the inspection history on the inspection history seal side, it is easy to identify whether or not the tampering has been completed. Also, a hole or the like is illegally drilled with a drill or the like in the back plate 38 on the side of the sealing base 22 at a portion corresponding to the pin fitting portion 32 to form an opening on the bottom side of the pin fitting portion 32, and from the opening side. Operate the sealing pins 37 to set the board case 6

Even if resin, adhesive, etc. are injected into the opening of 38 and closed,
Trace confirmation means composed of an irregular pattern on the back plate 38 side
Since there are 42, traces of perforations always remain on the side of the back plate 38, and the traces make it easy to find the fact of fraud.

Further, the pin holding portion 33 is separated from the case lid 16 by a cutting portion.
Since it protrudes through the pin 34, the cutting portion 34 can be easily cut by a nipper or the like at the time of opening, and since the cutting portion 34 is provided only on the pin holding portion 33 side, the pin fitting portion 32 and the pin holding
Compared to the case where the cutting portion 34 is provided in both the opening 33 and the opening 33, the cutting at the time of opening is easier and the opening can be easily performed. Pin fitting 3
2.Because the pin holding portion 33 protrudes outward, it does not become an obstacle even when resealing after inspection, the sealing pin 37 in the temporarily fixed state can be easily pressed by a driver etc., and the board case 6 can be easily resealed. In addition, since the sealing device 19 protrudes outward, the control device 7 in the substrate case 6 is not restricted by the sealing device 19, and the effective area of the control substrate 7 can be sufficiently secured.

A sealing base 22 is provided outside the case bottom plate 14,
Since the pin fitting portions 32 are formed on the sealing base 22, the strength of the pin fitting portions 32 can be increased as compared with the case where the pin fitting portions 32 are provided independently. In addition, the pin holder 33 on the case lid 16 abuts on the sealing base 22, and the respective pin holders
Since the tip of the sealing pin 37 in the temporarily fixed state at 33 is fitted to the pin fitting part 32 of the sealing base 22, each pin holding part 33 is cut into the cutting part 34.
Despite being provided on the case lid 16 via the pin, the state of the pin holding portion 33 is stable, and the sealing pin 37 is connected to the pin fitting portion 32.
There is no problem that the cut portion 34 is deformed or damaged when pressed to the side. As described above, the embodiment of the present invention has been described.
