Description

本発明は、遊技用の制御基板と、該制御基板を内部に収納する基板ボックスとを備えてなる遊技機に関する。 The present invention relates to a gaming machine including a control board for gaming and a board box for housing the control board therein.

遊技球の入賞・非入賞で遊技を行うパチンコ機や、複数の数字や図柄の組み合わせで遊技を行うスロットマシン等の遊技機には、箱の身に相当するベース部と、箱の蓋に相当するカバー部とを組み合わせてなる四角い基板ボックスに、遊技用の制御基板を収納してなる制御装置が取り付けられている。
この制御装置の制御基板によって遊技の動作が制御されるようになっているため、例えばベース部からカバー部を外し、制御基板に実装されたＲＯＭ等の電子部品を不正な改造品に交換する、等の不正工作が行われていた。
かかる不正工作を防止するため、封止状態の解除に一部の破壊を要する封止部（例えば、アンカーリベット及びワンウェイネジ等）でベース部とカバー部を封止するようにしている。 A gaming machine such as a pachinko machine that plays a game by winning or not winning a game ball, a slot machine that plays a game by combining a plurality of numbers or symbols, a base corresponding to the body of a box and a lid of the box A control device formed by storing a control substrate for gaming is attached to a square substrate box formed by combining the cover unit and the cover unit.
Since the operation of the game is controlled by the control board of the control device, for example, the cover is removed from the base, and electronic parts such as ROM mounted on the control board are replaced with illegally modified products, And other illegal work has been carried out.
In order to prevent such an illegal work, the base portion and the cover portion are sealed by a sealing portion (for example, an anchor rivet, a one-way screw, etc.) which requires a partial destruction to release the sealing state.

ところで近年では、基板ボックスを構成するベース部とカバー部が、靭性の高い樹脂（例えば、ポリカーボネート）で形成されるようになっている。そして、その靱性の高さを利用して前記封止をかい潜るような不正行為が行われるようになっていた。
すなわち、殆どの基板ボックスは、直方体形状であって、通常、短辺側に前記封止部が設けられている。そこで、封止部のない長辺側のほぼ中央付近でベース部とカバー部の側壁同士の合わせ目からマイナスドライバの先端を挿入し、そのままこじて撓ませながら隙間を広げ、大きくなった隙間から制御基板に対し前記のような不正工作を行うのである。この場合、ベース部とカバー部がそれぞれ靭性の高い樹脂で形成されているため、封止を維持したまま大きく撓ませても割れや変形等の痕跡が残り難い。そして、不正後は元の形状に戻るため、基板ボックスの外観変化による不正発見が困難となっている。 By the way, in recent years, the base part and cover part which comprise a substrate box are formed by resin (for example, polycarbonate) with high toughness. Then, the high level of the toughness is utilized to perform a cheating act that goes under the seal.
That is, most of the substrate boxes have a rectangular parallelepiped shape, and the sealing portion is usually provided on the short side. Therefore, insert the tip of the flathead screwdriver from the joint between the side walls of the base and the cover near the approximate center of the long side without the seal, insert the tip of the flat screwdriver as it is, and widen the gap while bending it as it is. The above-described tampering is performed on the control board. In this case, since the base portion and the cover portion are each formed of a resin having high toughness, traces of cracks, deformation, and the like hardly remain even if the base is largely bent while maintaining the sealing. And since it returns to the original shape after fraud, fraud detection by appearance change of a substrate box is difficult.

そこで本出願人は、かかる不正工作への対抗策として、ベース部のベース側壁にカバー部のカバー側壁を外嵌させて嵌め合わせる基板ボックスに対して、内嵌側のベース側壁に、外嵌側のカバー側壁の外側に被さるように山部と谷部が交互に連設された歯状壁を立設し、上記のように封止を維持したままドライバー等の異物でベース部とカバー部をこじ開けようとした場合に、歯状壁の山部が折れて不正工作の痕跡が残る技術を開発し、特許を取得した（特許文献１）。 Therefore, as a countermeasure against such improper work, the present applicant applies the cover side wall of the cover portion to the base side wall of the base portion by fitting the cover side wall on the inner side with respect to the base side wall. A tooth-shaped wall in which peaks and valleys are alternately arranged is erected so as to cover the outside of the cover side wall of the cover, and the base and the cover are covered with foreign matter such as a driver while maintaining the seal as described above. In an attempt to break open, a technology was developed in which the ridges of the toothed wall were broken and traces of tampering remained, and a patent was obtained (Patent Document 1).

特許第５０９７９５６号公報Patent No. 5097956

上記技術は、不正工作の発見に効果を発揮したが、従来の構成では、比較的小さい痕跡で且つ封止を維持したままベース部とカバー部をこじ開けることができる、という新たな問題点を発見した。 Although the above-mentioned technology has been effective in finding tampering , in the conventional configuration , a new problem has been found that the base part and the cover part can be opened with relatively small marks and maintaining the seal. did.

以上の構成である封止部１６Ｈ，１６Ｌのうち、高位置の封止部１６Ｈは、図７（ｂ）のようにカバー部１５のカバー側封止部１６Ｈｂをベース部１４のベース側封止部１６Ｈａに内嵌させて封止穴２５内のワンウェイネジ２８を締め込むと、図７（ａ）に示したようにアンカーリベット２７の端部が拡径してその力でベース側封止部１６Ｈａとカバー側封止部１６Ｈｂが接合される。そして、その状態で封止穴２５に封止キャップ２９を嵌め込んで塞ぐと、その封止キャップ２９が嵌め殺し状態に嵌って外れないため、ワンウェイネジ２８に触れることすらできなくなる。
また、もう一方の低位置の封止部１６Ｌも同様であって、カバー部１５のカバー側封止部１６Ｌｂをベース部１４のベース側封止部１６Ｌａに外嵌させて封止穴２５内のワンウェイネジ２８を締め込むと、アンカーリベット２７の端部が拡径してその力でベース側封止部１６Ｌａとカバー側封止部１６Ｌｂが接合される。そして、その状態で封止穴２５に封止キャップ２９を嵌め込んで塞ぐと、その封止キャップ２９が嵌め殺し状態に嵌って外れないため、ワンウェイネジ２８に触れることすらできなくなる。
したがって、ベース部１４とカバー部１５は、二つの封止部１６Ｈ，１６Ｌで封止されて開くことができない状態になっている。 Among the sealing portions 16H and 16L having the above configuration, the sealing portion 16H at the high position seals the cover-side sealing portion 16Hb of the cover portion 15 to the base side of the base portion 14 as shown in FIG. When the one-way screw 28 in the sealing hole 25 is tightened by being fitted inside the portion 16Ha, the end of the anchor rivet 27 is expanded as shown in FIG. The 16Ha and the cover-side sealing portion 16Hb are joined. And if the sealing cap 29 is inserted in the sealing hole 25 and closed in that state, since the sealing cap 29 will not be inserted and removed in the inserted state, it can not even touch the one-way screw 28.
The same applies to the other low position sealing portion 16L, and the cover side sealing portion 16Lb of the cover portion 15 is externally fitted to the base side sealing portion 16La of the base portion 14 so that the inside of the sealing hole 25 is formed. When the one-way screw 28 is tightened, the diameter of the end of the anchor rivet 27 is increased, and the base side sealing portion 16La and the cover side sealing portion 16Lb are joined by the force. And if the sealing cap 29 is inserted in the sealing hole 25 and closed in that state, since the sealing cap 29 will not be inserted and removed in the inserted state, it can not even touch the one-way screw 28.
Accordingly, the base portion 14 and the cover portion 15 are sealed by the two sealing portions 16H and 16L and can not be opened.

次に、回路基板１０の検査を行うために封止部１６Ｈ，１６Ｌによる封止を解除する場合は、例えば図７（ａ）の想像線Ｖ１と図８（ａ）の想像線Ｖ２で示したように、ベース側封止部１６Ｈａ，１６Ｌａ及びカバー側封止部１６Ｈｂ，１６Ｌｂの基端部（ベース部１４及びカバー部１５側の端部）とアンカーリベット２７との間の位置をカッター等の工具で破断する。これによりベース側封止部１６Ｈａ，１６Ｌａとカバー側封止部１６Ｈｂ，１６Ｌｂのアンカーリベット２７やワンウェイネジ２８で接合されていた部分が切り離されるから、封止が解けてベース部１４からカバー部１５を外すことができる。
このように封止部１６Ｈ，１６Ｌを破断した後のベース部１４とカバー部１５は、もはや再利用できないため、必要な検査を実施した後、回路基板１０を新しい基板ボックス８に付け替えてパチンコ機Ｐに戻す。 Next, when the sealing by the sealing portions 16H and 16L is released in order to inspect the circuit board 10, for example, the imaginary line V1 in FIG. 7A and the imaginary line V2 in FIG. 8A are shown. As described above, the position between the base end sealing portions 16Ha and 16La and the base end portions of the cover side sealing portions 16Hb and 16Lb (the end portions on the base portion 14 and the cover portion 15 side) and the anchor rivet 27 Break with a tool. As a result, the portions of the base side sealing portions 16Ha, 16La and the cover side sealing portions 16Hb, 16Lb joined by the anchor rivets 27 and the one-way screw 28 are separated, so the sealing is released and the base portion 14 to the cover portion 15 Can be removed.
As described above, since the base portion 14 and the cover portion 15 after breaking the sealing portions 16H and 16L can no longer be reused, the circuit board 10 is replaced with a new board box 8 and a pachinko machine after performing the necessary inspection. Return to P.

なお、実施形態１のように二つの封止部１６Ｈ，１６Ｌを設けて前側と後側の双方向から別々に封止するようにすれば、二つの封止部を同方向から封止する場合に比べて、より優れた防犯効果を発揮させることができる。
すなわち、例えば封止部１６Ｈ，１６Ｌのアンカーリベット２７を封止キャップ２９の反対側からドリル等で破壊して封止を解除するような手口に対し、そのような破壊痕が前後両面に残るため、どちらの向きからでも発見が容易になる。これがもし二つの封止部１６Ｈ，１６Ｌを同方向から封止する向きに並べた場合には、例えばカバー部１５側からドリルによる破壊痕が見えずに発見が遅れる、という事態が起こり得る。 In the case where two sealing portions 16H and 16L are provided as in the first embodiment and sealing is performed separately from the front and rear directions, the two sealing portions are sealed from the same direction. Compared with, you can make the crime prevention effect more excellent.
That is, for example, such destruction marks remain on both the front and rear sides with respect to a method such as breaking the anchor rivet 27 of the sealing portions 16H and 16L from the opposite side of the sealing cap 29 with a drill or the like to release the sealing. , It will be easier to find from either direction. When this arranges two sealing parts 16H and 16L in the direction which seals from the same direction, for example, the situation that a discovery is delayed without seeing the breakage mark by a drill from the cover part 15 side may occur.

また、実施形態１ではさらに防犯効果を高めるために、カバー側封止部１６Ｈａの端部に、該カバー側封止部１６Ｈａと同じ封止穴２５ｘと連通穴２６ｘを備えた連結部３０が、破断しやすくした易破断部３１を介して連設されている。
そして、図示を省略するが、他の制御装置や機構盤３側の部品等にベース側封止部１６Ｈａと同構造の受け側連結部を形成し、その受け側連結部と前記連結部３０を封止部１６Ｈと同じくアンカーリベット２７とワンウェイネジ２８と封止キャップ２９で連結すれば、そもそも基板ボックス８をパチンコ機Ｐから外す作業が容易でなくなるため、不正のための作業に時間が掛かる。犯罪者は、時間が掛かる作業を心理的に敬遠するため、より高い防犯効果を得ることができる。 Further, in the first embodiment, in order to further enhance the security effect, the connecting portion 30 provided with the same sealing hole 25x and communication hole 26x as the cover-side sealing portion 16Ha at the end of the cover-side sealing portion 16Ha It is continuously provided via the easily breakable portion 31 which is easily broken.
And although illustration is omitted, the receiving side connection part of the same structure as the base side sealing part 16Ha is formed in other control devices, parts by the side of the mechanism board 3, etc., and the receiving side connection part and the connection part 30 As in the case of the sealing portion 16H, if the anchor rivet 27, the one-way screw 28, and the sealing cap 29 are connected, the work of removing the substrate box 8 from the pachinko machine P is not easy in the first place. Offenders can avoid the time-consuming task psychologically, so they can achieve higher security effects.

しかして実施形態１の基板ボックス８には、カバー部１５の長手辺を構成するカバー側壁２１ａ，２１ｃの外側に歯状壁３２ａ，３２ｂが突設されている。
該歯状壁３２ａ，３２ｂは、略台形状の山部３３と略台形状の谷部３４が交互に連設された平歯車状であり、カバー部１５のカバー側壁２１ａ，２１ｃの後端から、ベース側壁１８ａ，１８ｃの後端を乗り越えてその外側に被さるようになっている。 In the substrate box 8 of the first embodiment, toothed walls 32a and 32b are provided on the outside of the cover side walls 21a and 21c that constitute the longitudinal sides of the cover portion 15.
The toothed walls 32a and 32b have a spur gear shape in which substantially trapezoidal ridges 33 and substantially trapezoidal valleys 34 are alternately provided, and from the rear end of the cover side walls 21a and 21c of the cover 15 , Over the rear end of the base side walls 18a and 18c and cover the outside.

一方、下側のベース側壁１８ｃには、図１、図５に示したように、前記歯状壁３２ｂの谷部３４を横断する横断突部３５ａと、該横断突部３５ａから反山部３３側に向けて折り返す立設部３５ｂと、からなる断面略Ｌ字状のガード部３５が形成されている。
実施形態１のガード部３５は、全ての立設部３５ｂが繋がって帯板状に連続しており、したがって形態上は、ベース側壁１８ｃの外面に、前記歯状壁３２ｂの谷部３４を横断する向きの横断突部３５ａと反山部３３側に向かう立設部３５ｂとからなる断面略Ｌ字状のガード部３５を突設し、該ガード部３５の横断突部３５ａに歯状壁３２ｂの山部３３を通す貫通孔を破線状に形成すると共に貫通孔同士の間の横断突部３５ａを歯状壁３２ｂの谷部３４に整合させるようにした、と見てもよい。
このように実施形態１のガード部３５は、立設部３５ｂが帯板状に連続しているため、該立設部３５ｂの強度が増すことはもちろん、点在する横断突部３５ａ，３５ａ…同士が互いに連結されることで相乗的に強度が増す。 On the other hand, as shown in FIGS. 1 and 5, on the lower side wall 18c of the lower side, a cross projection 35a crossing the valley 34 of the toothed wall 32b, and an anti-peak portion 33 from the cross projection 35a. A guard portion 35 having a substantially L-shaped cross section is formed, which includes an erected portion 35b that is folded back toward the side.
In the guard portion 35 of the first embodiment, all the erected portions 35b are connected and continuous in the form of a strip, and therefore the configuration crosses the valleys 34 of the toothed wall 32b on the outer surface of the base side wall 18c. The guard portion 35 having a substantially L-shaped cross section is formed by protruding the cross projection 35a in the same direction and the standing portion 35b toward the anti-peak portion 33, and the toothed wall 32b is formed on the cross projection 35a of the guard portion 35. It can be seen that the through holes passing through the ridges 33 are formed in a broken line and the cross projections 35a between the through holes are aligned with the valleys 34 of the toothed wall 32b.
As described above, in the guard portion 35 of the first embodiment, since the standing portion 35b is continuous in a band plate shape, it is needless to say that the strength of the standing portion 35b is increased, and the cross projections 35a, 35a ... The strength is increased synergistically by connecting each other.

なお、ガード部３５の立設部３５ｂは、その端部が、図６に示したようにベース部１４のベース側壁１８ｃの端部より後方に突出している。このようにガード部３５の立設部３５ｂの端部とベース側壁１８ｃの端部の位置を揃えることなく前後方向に段違い状にしておけば、後方に突出した要素、つまり実施形態１では立設部３５ｂが、該立設部３５ｂとベース側壁１８ｃの間に歯状壁３２ｂを円滑に導き入れるガイドの役割を果たす。 The end of the standing portion 35b of the guard portion 35 protrudes rearward from the end of the base side wall 18c of the base portion 14 as shown in FIG. If the end of the erected portion 35b of the guard portion 35 and the end of the base side wall 18c are thus staggered in the front-rear direction without aligning them, an element protruding rearward, that is, erected in the first embodiment The portion 35b serves as a guide for guiding the toothed wall 32b smoothly between the standing portion 35b and the base side wall 18c.

以上の構成である実施形態１の基板ボックス８は、歯状壁３２ｂの谷部３４がガード部３５で保護されるため、そこにドライバー等の異物を差し込むことが困難になる。したがって、歯状壁３２ｂの谷部３４に異物を差し込んで隙間をこじ開けようとする不正を封じることができる。
また、仮に不正者が、歯状壁３２ｂの谷部３４への異物の差込みを諦め、その異物を山部３３とベース側壁１８ｃの間に差し込んでこじた場合でも、その力で山部３３が折れる（完全に破断する場合と折れ曲がる場合の何れをも含む。）ため、事後の発見が容易になる。もっとも、実施形態１のベース側壁１８ｃは、突設したガード部３５が補強リブの役割を果たして強度が向上しているため、異物で隙間を開けることも容易でない。
なお、実施形態１では、ガード部３５がベース側壁１８ｃのみに形成されていて、もう一方のベース側壁１８ａには形成されていないため、不正者がカバー側壁２１ａの歯状壁３２ａの谷部３４を狙う可能性もある。
しかし、カバー側壁２１ａとＲＯＭ１１ｘとの間には回路基板１０のコネクター１２，１２…に対応するコネクタ凹部２３があってその領域が障害になるため、敢えてガード部３５を設けなくともＲＯＭ１１ｘへの到達は容易でない。もっとも、カバー側壁２１ａの歯状壁３２ａに対応するベース側壁１８ａに、上記と同様のガード部を設けてももちろんよい。
また、図１０に示したように、制御装置７をパチンコ機Ｐに設置した状態で、カバー側壁２１ａの直上に制御装置７０があって不正を行う作業空間が殆どないため、カバー側壁２１ａへの不正工作は容易でない。 In the substrate box 8 according to Embodiment 1 having the above-described configuration, the valley portion 34 of the toothed wall 32b is protected by the guard portion 35, so that it is difficult to insert foreign matter such as a driver into the valley portion 34. Therefore, it is possible to seal foreign matters which are inserted into the valley portion 34 of the toothed wall 32b and try to open the gap.
Also, even if the injustice gives up the insertion of the foreign matter into the valley 34 of the toothed wall 32b, and inserts the foreign matter between the ridge 33 and the base side wall 18c and pricks up, the ridge 33 Because it is broken (including both the case of complete breakage and the case of bending), subsequent detection is facilitated. However, in the base side wall 18c of the first embodiment, since the protruding guard portion 35 plays the role of a reinforcing rib and the strength is improved, it is not easy to make a gap with foreign matter.
In the first embodiment, since the guard portion 35 is formed only on the base side wall 18c and not formed on the other base side wall 18a, an unauthorized person may form the valley portion 34 of the toothed wall 32a of the cover side wall 21a. There is also the possibility of aiming for
However, since there is a connector recess 23 corresponding to the connector 12, 12 ... of the circuit board 10 between the cover side wall 21a and the ROM 11x and the area becomes an obstacle, even if the guard portion 35 is not provided, reaching the ROM 11x Is not easy. Of course, a guard portion similar to the above may be provided on the base side wall 18a corresponding to the toothed wall 32a of the cover side wall 21a.
Further, as shown in FIG. 10, with the control device 7 installed on the pachinko machine P, since the control device 70 is right above the cover side wall 21a and there is almost no work space for performing fraud, to the cover side wall 21a Tampering is not easy.

［その他］
実施形態１の基板ボックス８には、封止部１６Ｈ，１６Ｌのベース部１４とカバー部１５側の端部を基端部としたとき、図７（ａ）、図８（ａ）に示したように、中空状の封止部１６Ｈ，１６Ｌ内であって封止解除のための破断領域３６の前記基端部側に、破断時に破断領域３６に発生する屑類の、ベース部１４とカバー部１５の内部空間８ｓ内への侵入を防止する隔壁部３７が設けられている。
低位置の封止部１６Ｌの隔壁部３７は、ベース部１４のベース側封止部１６Ｌａに一体成形された衝立であって、その突出部分がカバー部１５のカバー側封止部１６Ｌｂ内に嵌まるようになっている。なお、隔壁部３７は、カバー部１５のカバー側封止部１６Ｌｂに一体成形して突出部分をベース部１４のベース側封止部１６Ｌａに嵌めるか、或はベース部１４のベース側封止部１６Ｌａと、カバー部１５のカバー側封止部１６Ｌｂに隔壁部３７をほぼ１／２ずつ成形して中間で継ぎ合わせるようにしてもよい。
また、高位置の封止部１６Ｈの隔壁部３７は、図７（ａ）に示したようにカバー外壁２１０によって代用されており、該隔壁部３７がベース部１４のベース側壁１８ｂに浅く当接して前記屑類の回路基板１０側への移動を遮断する。
上記のように実施形態１の制御装置７は、回路基板１０の検査を行うために封止部１６Ｈ，１６Ｌの封止を解除（封止部を破断）するのであるが、封止部１６Ｈ，１６Ｌを破断する作業で発生する樹脂の切り屑等が回路基板１０の電子部品１１，１１…等に付着すると後々故障の原因になる。
言うまでもなく中空状の封止部１６Ｈ，１６Ｌと、ベース部１４及びカバー部１５の内部空間８ｓとの間にはベース側壁１８ｂとカバー側壁２１ｂの嵌め合わせ部が存在するのであるが、両側壁１８ｂ，２１ｂの間にはベース部１４とカバー部１５を嵌め合わせる際の遊び、つまり隙間が不可欠であるため、隔壁部３７で屑類の移動を遮断する効果は大きい。 [Others]
In the substrate box 8 of the first embodiment, when the end portions on the base portion 14 and the cover portion 15 side of the sealing portions 16H and 16L are used as the base end portions, they are shown in FIGS. 7A and 8A. As described above, the base portion 14 and the cover of scraps generated in the fracture area 36 at the time of fracture, on the base end side of the fracture area 36 for breaking the seal within the hollow sealing parts 16H and 16L. The partition part 37 which prevents the penetration | invasion in the interior space 8s of the part 15 is provided.
The partition 37 of the low sealing portion 16L is a partition integrally formed on the base-side sealing portion 16La of the base portion 14, and the projecting portion thereof is fitted in the cover-side sealing portion 16Lb of the cover portion 15. It is supposed to be full. The partition 37 may be formed integrally with the cover-side sealing portion 16Lb of the cover portion 15 and the projecting portion may be fitted to the base-side sealing portion 16La of the base portion 14, or the base-side sealing portion of the base 14 The partition wall portion 37 may be formed into approximately half each on the cover-side sealing portion 16Lb of the cover portion 15 and 16La, and may be joined in the middle.
Further, as shown in FIG. 7A, the partition wall 37 of the sealing portion 16H at the high position is substituted by the cover outer wall 210, and the partition wall 37 abuts on the base side wall 18b of the base portion 14 shallowly. Thus, the movement of the wastes to the circuit board 10 side is blocked.
As described above, the control device 7 of the first embodiment releases the sealing of the sealing portions 16H and 16L (breaks the sealing portion) in order to inspect the circuit board 10. However, the sealing portion 16H, If resin chips or the like generated in the work of breaking 16 L adhere to the electronic components 11, 11 ... etc. of the circuit board 10, it will cause a later failure.
Needless to say, a fitting portion of the base side wall 18b and the cover side wall 21b exists between the hollow sealing portions 16H and 16L and the internal space 8s of the base portion 14 and the cover portion 15, but both side walls 18b , 21b, the gap between the base portion 14 and the cover portion 15 is indispensable. Therefore, the partition wall 37 has a great effect of blocking the movement of debris.

さらに実施形態１の基板ボックス８には、図１、図２、図３、図５、図６に示したようにカバー部１５のカバー面板２０に、回路基板１０のＲＯＭ１１ｘを着脱するのに必要なスペース以下の隙間Ｓを開けて該ＲＯＭ１１ｘの後面に対接するＲＯＭ用ガード部３８が設けられている。
実施形態１のＲＯＭ用ガード部３８は、図１、図２、図３、図５、図６に示したように、カバー部１５のカバー面板２０を凹状に窪ませて成形したもので、ＲＯＭソケット１３を含むＲＯＭ１１ｘの全体をカバーする大きさであり、該ＲＯＭ用ガード部３８に当たってＲＯＭソケット１３の解除が出来ないようになっている。
また、ＲＯＭ用ガード部３８には、ＲＯＭ１１ｘの両側に該ＲＯＭ１１ｘの移動を規制する脚状のストッパー３９が突設されており、仮にＲＯＭソケット１３が不正に解除されたとしてもＲＯＭ１１ｘが抜けないように二重のロックが設けられている。 Furthermore, as shown in FIGS. 1, 2, 3, 5, and 6, the board box 8 of the first embodiment is required for attaching and detaching the ROM 11 x of the circuit board 10 to the cover surface plate 20 of the cover portion 15. A ROM guard portion 38 is provided in contact with the rear surface of the ROM 11x with a space S smaller than the above space.
The ROM guard portion 38 according to the first embodiment is formed by recessing the cover face plate 20 of the cover portion 15 into a concave shape as shown in FIG. 1, FIG. 2, FIG. 3, FIG. It has a size that covers the whole of the ROM 11x including the socket 13, and can not be released from the ROM socket 13 by hitting the ROM guard portion 38.
Further, leg-like stoppers 39 for restricting the movement of the ROM 11x are provided on both sides of the ROM 11x in the guard portion 38 for ROM so that the ROM 11x is not removed even if the ROM socket 13 is released illegally. There is a double lock on the

また、実施形態１のパチンコ機Ｐは、図１０に示したように、制御装置７の下側、つまりガード部３５を設けた側に、少なくとも手持ち可能な鏡（図示せず）を差し入れてガード部３５沿いに移動させ得る点検空間ＣＳが設けられている。
この点検空間ＣＳに鏡を差し入れて鏡像で歯状壁３２ｂをチェックするようにすれば、作業者が一々しゃがんで歯状壁３２ｂを下から見上げなくとも、立ったままの楽な姿勢で効率良く点検を実施することができる。
もちろんこのような点検空間ＣＳは、不正を行おうとする者にとっても格好の作業空間になり得るが、実施形態１の基板ボックス８は、ガード部３５によって不正に対する防御力が向上しているため、総合的に利益の方が上回る。 Further, as shown in FIG. 10, the pachinko machine P of the first embodiment inserts at least a mirror (not shown) which can be held on the lower side of the control device 7, that is, the side provided with the guard portion 35. An inspection space CS which can be moved along the portion 35 is provided.
By inserting a mirror in this inspection space CS and checking the toothed wall 32b in a mirror image, the worker can efficiently stand in a comfortable posture as it stands, without looking up from the bottom of the toothed wall 32b. You can carry out an inspection.
Of course, such an inspection space CS can be a suitable work space also for those who intend to conduct fraud, but the board box 8 of the first embodiment has an improved protection against fraud by the guard portion 35, Overall, the profit outweighs.

［実施形態２］
図１１〜図１３は、実施形態２の制御装置７を示したものである。
この実施形態２の制御装置７は、ベース側壁１８ｃのガード部３５の立設部３５ｂが、各横断突部３５ａごとに独立している。この場合、実施形態１に比べて立設部３５ｂの強度が低下するものの、立設部３５ｂが破壊されればその痕跡が明瞭に残るため不正の発見は容易である。
なお、図１１〜図１３において実施形態１と同一又は同機能の要素に同じ符合を付して説明を省略する。 Second Embodiment
11 to 13 show a control device 7 of the second embodiment.
In the control device 7 of the second embodiment, the standing portion 35b of the guard portion 35 of the base side wall 18c is independent for each of the cross projections 35a. In this case, although the strength of the erected portion 35b is reduced compared to the first embodiment, if the erected portion 35b is destroyed, the trace of the erected portion 35b is clearly left, so that it is easy to find fraud.
In FIGS. 11 to 13, elements that are the same as or have the same functions as in Embodiment 1 are given the same reference numerals, and descriptions thereof will be omitted.

以上、本発明を実施形態１、２について説明したが、もちろん本発明は、上記実施形態１、２に限定されるものではない。例えば、実施形態１，２では、主として図柄表示装置や音響装置或は照明装置等を制御する副制御装置７について説明したが、封止構造を備えていることを条件として主制御装置７０でも同様に適用可能である。
また、実施形態１，２では、ベース部１４のベース側壁１８ａ〜１８ｄにカバー部１５のカバー側壁２１ａ〜２１ｄを内嵌させるようにしたが、逆にカバー側壁２１ａ〜２１ｄをベース側壁１８ａ〜１８ｄに外嵌させて嵌め合わせるようにしてもよい。その場合、内嵌側のベース側壁１８ｃに、外嵌側のカバー側壁２１ｃの外側に被さるように歯状壁３２ｂが形成され、一方、外嵌側のカバー側壁２１ｃにガード部３５が形成される。
また、実施形態１，２では、ガード部３５を断面Ｌ字状に形成したが、ガード部３５を構成する横断突部３５ａと立設部３５ｂが、例えば断面Ｃ字状のカーブを描いて連続するようになっていてもよい。
また、実施形態１，２では一回分の封止部１６Ｈ，１６Ｌを設けて検査のたびに基板ボックス８を使い捨てるようにしたが、複数回分の封止部を設けてそれを使い分けることにより、基板ボックス８を複数回開閉封止し得るようにしてもよい。 The present invention has been described above with reference to the first and second embodiments, but the present invention is of course not limited to the first and second embodiments. For example, in the first and second embodiments, the sub control device 7 mainly controlling the symbol display device, the sound device, the lighting device, etc. has been described, but the main control device 70 may also be the same as long as the sealing structure is provided. Applicable to
Further, in the first and second embodiments, the cover side walls 21a to 21d of the cover unit 15 are internally fitted to the base side walls 18a to 18d of the base portion 14. Conversely, the cover side walls 21a to 21d are the base side walls 18a to 18d. It may be fitted on the outside. In that case, the toothed wall 32b is formed on the inner fitting side base wall 18c so as to cover the outside of the outer fitting side cover sidewall 21c, while the guard portion 35 is formed on the outer fitting side cover sidewall 21c. .
Further, in the first and second embodiments, the guard portion 35 is formed to have an L-shaped cross section, but the cross projection 35 a and the standing portion 35 b constituting the guard portion 35 draw a curve having a C-shaped cross section, for example, and are continuous. You may come to
In the first and second embodiments, the sealing portions 16H and 16L for one time are provided, and the substrate box 8 is disposable each time the inspection is performed. However, by providing sealing portions for a plurality of times and using them separately, The substrate box 8 may be closed and sealed several times.

また、実施形態１，２では、歯状壁３２ｂとガード部３５が、長手辺を構成するカバー側壁２１ｃとベース側壁１８ｃに設けられている構成を例示したが、ベース部１４とカバー部１５の間をこじ開けて隙間を作る不正を防止するという観点からは、歯状壁３２ｂとガード部３５を設ける位置として、ベース部１４とカバー部１５を固定する複数の固定部（例えばヒンジ受部とヒンジ掛け部による結合部や封止部）の間隔が、ベース部１４とカバー部１５の間をこじ開ける力を受けて不正可能な隙間が生じ得る程度に離れている領域、としてもよい。そのような領域として、ベース部１４とカバー部１５の封止部が設けられていない辺、或は、封止部が設けられている辺であって封止部と隣の辺との間がある。 In the first and second embodiments, the toothed wall 32b and the guard portion 35 are illustrated as being provided on the cover side wall 21c and the base side wall 18c forming the longitudinal side. From the point of view of preventing irregularities by opening the gap, a plurality of fixing portions (for example, a hinge receiving portion and a hinge) for fixing the base portion 14 and the cover portion 15 as a position where the toothed wall 32b and the guard portion 35 are provided.
