本発明は、遊技機（パチンコ機等）の遊技内容を制御する制御基板を格納する制御箱であって、不正行為を阻止する制御箱に関する。
【０００２】
【従来の技術】
遊技機（パチンコ機等）には、遊技内容を制御する制御基板を配設の制御箱が着脱自在に取り付けてあり、遊技者に興趣を与えるために、遊技内容の変更を容易としている。
前記制御基板には、ＣＰＵ、ＲＯＭ等の制御素子が配置してあり、とりわけ制御ソフトが記録してあるＲＯＭが重要な役割を果たす。そこで、かかるＲＯＭを取り替えて、不正に異なるゲームとすることを禁止するため、制御箱には封印紙が貼着してあって、容易に不正ができないようになっている。
【０００３】
【発明が解決しようとする課題】
しかしながら、特殊な液体を使用して、封印紙を傷つけることなく、且つ封印紙が貼ってあった痕跡を残すことなく剥し、不正なＲＯＭと交換した後に、同じ封印紙を貼る不正改造を行う行為が行われている。
従って、かかる不正行為を容易に行わない対策が望まれ、本発明はかかる課題を解消する制御箱を提供するものである。
【０００４】
【課題を解決するための手段】
請求項１の制御箱は、遊技機の制御をなす制御素子等を搭載の制御基板を格納する表カバー体と裏カバー体で構成してあり、表カバー体と裏カバー体の何れか一方のカバー体の側部には薄板状の止着部材が曲折可能に一体成形してある。
又、前記止着部材には第１止着部材Ａと第２止着部材Ｂがあり、前記第１止着部材Ａにはネジ孔（１８ａ）が穿設してあると共に、切込み窓（１７ａ）が形成してあり、前記第２止着部材Ｂには第１係止爪（２０ａ）と第２係止爪（２０ｂ）及び切込み窓（１７ｂ）が形成してある。
他方のカバー体には、前記第１止着部材Ａに穿設のネジ孔（１８ａ）に対応するネジ孔（１８ｂ）が穿設してある。一方のカバー体には、前記第２止着部材Ｂに形成の第１係止爪（２０ａ）に対応する第１係止孔（２２ａ）が穿設されていると共に、前記他方のカバー体には前記第２止着部材Ｂに形成の第２係止爪（２０ｂ）に対応する第２係止孔（２２ｂ）が穿設されている。
そして、取り付けると抜くことが不可能なタイプのネジを、前記第１止着部材Ａに穿設のネジ孔（１８ａ）と前記他方のカバー体に穿設のネジ孔（１８ｂ）に挿通して、第１止着部材Ａを介して前記一方のカバー体と前記他方のカバー体を固定する。
そして、前記切込み窓（１７ａ）に沿って第１止着部材Ａを切断すると共に、前記切込み窓（１７ｂ）に沿って第２止着部材Ｂを切断することにより前記一方のカバー体と前記他方のカバー体を開くことができる。
その後、前記一方のカバー体に穿設の第１係止孔（２２ａ）に前記第２止着部材Ｂに形成の第１係止爪（２０ａ）を係止すると共に、前記他方のカバー体に穿設の第２係止孔（２２ｂ）に前記第２止着部材Ｂに形成の第２係止爪（２０ｂ）を係止することにより表カバー体と裏カバー体を再度固定可能である。
【０００５】
又、請求項２の遊技機の制御箱は、破断ネジで表カバー体と裏カバー体を固定するので、簡便な作業で表カバー体と裏カバー体を固定できるし、頭部が破断されるので、破断ネジを緩めて制御箱を開くことができない。
【０００６】
【発明の実施の形態】
遊技機としてパチンコ機を例にとって説明すると、パチンコ機は遊技球が特定箇所に入賞すると、図柄表示器を介して遊技者にとって有利な大当たり等を生起して多量の景品球を払い出す。このような、遊技内容を制御するために、パチンコ機の裏面には制御箱１内に、「ＲＯＭ等の制御素子」を搭載の制御基板（図示略）をビス等で固定して格納してある。
【０００７】
図１はよく知られたパチンコ機の裏面図であり、裏面中央には遊技盤の表側に配設の入賞口等に入賞した遊技球を集めて、入賞球処理装置６２に１球毎分離処理させる入賞球集合樋６１が設けてある。この入賞球集合樋６１の左下方には、入賞球や賞品球等のゲーム処理を行う制御素子を搭載の制御基板を内蔵の制御箱１が配設してあると共に、右下方には、球貸機７０からの信号に基づく貸球等の処理信号をパチンコ機と送受信するインターフェイス基板８０が設置してある。
【０００８】
又、パチンコ機の上部には、排出前の遊技球を貯留しておく貯留タンク６３が設けてあり、その貯留タンク６３から遊技球を二列に整列させて遊技球排出装置６５まで誘導する整列樋６４が設置してある。この整列樋６４には、遊技球の重なりを防止する球ならし６６が揺動自在に垂設してある。又、前記遊技球排出装置６５から排出の遊技球は流下樋６７を経て上皿に流出する。又、パチンコ機の上部右側にはターミナル基板６９が取り付けてあり、左下部には遊技球発射装置９１が設けてあって一球毎発射可能としている。
【０００９】
図２は制御箱１の部品分解図であって、この制御箱１は箱状の表カバー体１０と裏カバー体１１、制御素子を取付の制御基板１２とその制御基板を固定するシャーシ１３とで構成する。
また、止着部材Ａ、Ｂについては、拡大図を示す図３（Ａ）、図３（Ａ）のＡ〜Ａ断面を示す図３（Ｂ）、図３（Ａ）のＢ〜Ｂ断面を示す図３（Ｃ）、図３（Ｄ）の止着部材Ｂの斜視図を参照して説明する。
表カバー体１０は合成樹脂等で裏カバー体１１に装着可能に製作され、表カバー体１０の内側には凹部４０ａが、一方、裏カバー体１１には前記凹部４０ａに対応する位置に突部４０ｂが形成してあって位置決めをなす。
又、表カバー体１０の両側面１０ａには、後述する切込み窓１７ａ、１７ｂの部分まで０．５〜１．０ｍｍの薄板状の止着部材Ａ、Ｂが、容易に曲折可能に一体成形してある。
又、止着部材Ａには、切込み窓１７ａがハサミ等で容易に切断可能に適宜の間隔で形成してあると共にネジ孔１８ａが穿設してある。一方、裏カバー体１１の側面１１ａには、止着部材Ａのガイド堤１９が形成してあると共に前記ネジ孔１８ａに対応する位置にネジ孔１８ｂが穿設してある。
【００１０】
一方、第２止着部材Ｂも同様に、切込み窓１７ｂがハサミ等で容易に切断可能に適宜の間隔で形成してある。又、第２止着部材Ｂには、前記切込み窓１７ｂから先端部の間に、一対の係止爪（第１係止爪）２０ａ、係止爪（第２係止爪）２０ｂが互いに異なる向きに設けてある。尚、この係止爪２０ａ、２０ｂの向きは、図３（Ｃ）に示す方向の他、各々反対方向に形成してもよい。
又、裏カバー１１の側面１１ａには、前記係止爪２０ｂに対しては係止可能な大きさの係合孔２１ｂが形成してある一方、係止爪２０ａに対しては、装着しても係止しない大孔２１ａが表カバー体１０の側面１０ａに形成してある。
【００１１】
又、表カバー体１０と裏カバー体１１の側面１０ａ、１１ａには、後記で詳述する、前記係止爪２０ａ、２０ｂに係止可能な係止孔（第１係止孔）２２ａ、係止孔（第２係止孔）２２ｂが各々穿設してあると共に、第２止着部材Ｂの両縁のガイド堤２３ａ、２３ｂが形成してある。
【００１２】
次に、前記構成の止着部材Ａ、Ｂによって表カバー体１０と裏カバー体１１を固定する方法について説明する（図４参照）。
先ず、制御素子を取付の制御基板１２をシャーシ１３にビス等で固定し、そのシャーシ１３を裏カバー体にビス等で固定する。そして、表カバー体１０を裏カバー体１１に装着し、止着部材Ａを折り曲げて、ネジ孔１８ａをネジ孔１８ｂに合わせて、そのネジ孔に破断ネジ１６を取り付ける。この破断ネジ１６は所定トルク以上かかると頭部が切断されるため、止着部材Ａは頭部が欠落した状態で固定されるため、破断ネジ自体を引き抜くことは不可能となる。従って、表カバー体１０と裏カバー体１１を開くためには、止着部材Ａを切断する必要がある。
【００１３】
一方、止着部材Ｂを折り曲げて、係止爪２０ｂを係合孔２１ｂに装着すると、係止爪２０ｂは係合孔２１ｂに係止状態となる。しかし、係止爪２０ａは大孔２１ａとは係止状態とならない。即ち、係止爪２０ｂは係合孔２１ｂとで係止状態となるが、係止爪２０ａは大孔２１ａに対しては何等影響ない状態となる（図４（Ｂ））が、この止着部材Ｂによって表カバー体１０と裏カバー体１１は固定される。
【００１４】
以上のように、制御箱１は表カバー体１０と裏カバー体１１を止着部材Ａ、Ｂによって固定されるため、制御箱１を開くには、特に止着部材Ａを切断しない限り困難であり、開いたときにはその痕跡が残って不正行為が判る。
【００１５】
次に、前記制御箱１内「ＲＯＭ等の制御素子」を点検するために制御箱を開く操作と再度組み立てる操作について説明する（図５参照）。
先ず、ハサミ等で、止着部材Ａ、Ｂに形成の切込み窓１７ａ、１７ｂに沿って切断すると、表カバー体１０と裏カバー体１１は分離可能となる。そこで、制御素子（図示略）を取り出して、点検をした後に再度取り付ける。
そして、表カバー体１０と裏カバー体１１を突き合わせて装着するが、止着部材Ａは切込み窓１７ａで切断されて、端部Ａ１は表カバー体１０に、他端部は裏カバー体１１に破断ネジ１６で固定した状態のままとなる。従って、この止着部材Ａは表カバー体１０と裏カバー体１１を固定しない。
【００１６】
一方、止着部材Ｂは切込み窓１７ｂで切断されて残部Ｂ１は表カバー体１０に残る一方、切断止着部材Ｂ’の係止爪２０ａは大孔２１ａと係止状態でないため、係止爪２０ｂを動かすことによって、容易にその切断止着部材Ｂ’を係合孔２１ｂから抜くことができる。
そして、その切断止着部材Ｂ’に形成の係止爪２０ａ、２０ｂを係止孔２２ａ、２２ｂに装着すると、係止爪２０ａ、２０ｂは各々係止孔２２ａ、２２ｂに係止状態となる。これらの係止爪２０ａ、２０ｂは互いに異なる向きに形成してあるため、切断止着部材Ｂ’を抜くためには、前後（上下）に動かすことを要するが、かかる動作をしても係止爪２０ａ、２０ｂの向きによって抜くことは困難である。従って、表カバー体１０と裏カバー体１１は切断止着部材Ｂ’によって固定され、この切断止着部材Ｂ’を切断しない限り開くことは困難となる。
【００１７】
次に、図６に示すように、止着部材Ａ、Ｂの変更例を示す。
図６（Ａ）は止着部材Ｂの変更例であり、この止着部材Ｂ1に形成の係止爪２０ａ、２０ｂは３片で構成し、両側の係止爪部２５ａ、２６ａの向きは、図３（Ｃ）に示すと同じであるが、中央の係止爪部２５ｂ、２６ｂは相互に逆向きに形成する。尚、係合孔２１Ａは係止爪２０ａ（係止爪部２５ａ、２５ｂ）に係止できない大きさの孔に形成し、係合孔２１Ｂは係止爪２０ｂ（係止爪部２６ａ、２６ｂ）に係止可能とするので、係止爪２０ｂを係合孔２１Ｂに装着すると、前記両側に形成の係止爪２６ａ、２６ｂによって、前記図３（Ｃ）に示す係止爪２０ｂに比べて引き抜くことが困難となる。
【００１８】
図６（Ｂ）は止着部材Ａの変更例を示す。この止着部材Ａ1は端部を表カバー体に固定しない独立の片体であり、端部に貫通孔３０を穿設してある。又、その貫通孔３０に対応する位置の表カバー体１０にネジ孔（図示略）を明けておく。そして、止着部材Ａ1は、表カバー体１０と裏カバー体１１に当てて、ネジ孔１８ａと貫通孔３０の双方に破断ネジ１６を介して固定する。このように固定することによって、表カバー体１０と裏カバー体１１は固定され、止着部材Ａ1を切断しない限り開くことができない。
このように、止着部材Ａ1を構成することもでき、必ずしも、図３に示すように端部を表カバー体１０に固着して構成する必要はない。
【００１９】
図６（Ｃ）（Ｄ）は止着部材Ｂの変更例であり、何れも端部を表カバー体１０に固着しなくて独立した片体で構成するものである。
図６（Ｃ）は貫通孔３５を明けると共にその位置にあわせて表カバー体１０に孔を穿設して置く。そして、この止着部材Ｂ1を破断ネジ１６を介して表カバー体１０と裏カバー体１１に固定する方法である。
又、図６（Ｄ）は係止爪３６を新たに形成すると共に、この係止爪３６に係止可能な係合孔を表カバー体１０に穿設する構成であってもよい。
以上のように、止着部材Ａ、Ｂは、図３に示すように、表カバー体１０に端部を固定して曲折可能とする必要はなく独立片で構成してもよい。
尚、止着部材Ａ、Ｂが固定してあるのは、図３に示すように表カバー体１０側であるが、裏カバー体１１側に固定してもよいことはいうまでもない。
【００２０】
【発明の効果】
請求項１の制御箱は、固定された表カバー体と裏カバー体を開くときには、第１止着部材Ａと第２止着部材Ｂに形成の切込み窓をハサミ等で切断することによってできる。そして、再度、表カバー体と裏カバー体を固定するには、第２止着部材Ｂに形成の係止爪を、表カバー体と裏カバー体に穿設の係止孔に係止することによって行うことができる。
又、請求項２の遊技機の制御箱は、破断ネジを使用することによって、簡便な作業で表カバー体と裏カバー体を固定できるし、頭部が破断されるので、破断ネジを緩めて制御箱を開くことができない。

Moreover, about the fastening members A and B, FIG. 3 (A) which shows an enlarged view, FIG. 3 (B) which shows the AA cross section of FIG. 3 (A), and the BB cross section of FIG. 3 (A). It demonstrates with reference to the perspective view of the fastening member B of FIG.3 (C) and FIG.3 (D) which show.
The front cover body 10 is made of synthetic resin or the like so that it can be attached to the back cover body 11. A recess 40 a is formed on the inner side of the front cover body 10, while a protrusion is formed on the back cover body 11 at a position corresponding to the recess 40 a. 40b is formed for positioning.
Further, on both side surfaces 10a of the front cover body 10, thin plate-like fastening members A and B having a thickness of 0.5 to 1.0 mm are integrally formed so as to be easily bent up to the later-described cut windows 17a and 17b. It is.
Further, the fastening member A is formed with cutting windows 17a formed at appropriate intervals so as to be easily cut by scissors or the like and screw holes 18a. On the other hand, a guide bank 19 for the fastening member A is formed on the side surface 11a of the back cover body 11, and a screw hole 18b is formed at a position corresponding to the screw hole 18a.
[0010]
On the other hand, in the second fastening member B, similarly, the cut windows 17b are formed at appropriate intervals so that they can be easily cut with scissors or the like. The second fastening member B has a pair of locking claws (first locking claws) 20a and locking claws (second locking claws) 20b between the cut window 17b and the tip. It is provided in the direction. In addition, you may form the direction of this latching claw 20a, 20b in each other direction other than the direction shown in FIG.3 (C).
Further, the side surface 11a of the back cover 11 is formed with an engagement hole 21b having a size capable of being locked with the locking claw 20b, while being attached to the locking claw 20a. A large hole 21 a that is not locked is formed in the side surface 10 a of the front cover body 10.

Further, the side surfaces 10a and 11a of the front cover body 10 and the back cover body 11 have locking holes (first locking holes) 22a that can be locked to the locking claws 20a and 20b, which will be described in detail later. Stop holes (second locking holes) 22b are respectively formed, and guide ridges 23a and 23b on both edges of the second fixing member B are formed.
[0012]
Next, a method of fixing the front cover body 10 and the back cover body 11 with the fastening members A and B having the above-described configuration will be described (see FIG. 4).
First, the control board 12 to which the control element is attached is fixed to the chassis 13 with screws or the like, and the chassis 13 is fixed to the back cover body with screws or the like. Then, the front cover body 10 is attached to the back cover body 11, the fastening member A is bent, the screw hole 18a is aligned with the screw hole 18b, and the fracture screw 16 is attached to the screw hole. Since the head of the breaking screw 16 is cut when a predetermined torque or more is applied, the fastening member A is fixed in a state in which the head is missing, so that the breaking screw itself cannot be pulled out. Therefore, in order to open the front cover body 10 and the back cover body 11, it is necessary to cut the fastening member A.
[0013]
On the other hand, when the fastening member B is bent and the locking claw 20b is attached to the engagement hole 21b, the locking claw 20b is locked to the engagement hole 21b. However, the locking claw 20a is not locked with the large hole 21a. That is, the locking claw 20b is locked with the engagement hole 21b, but the locking claw 20a has no influence on the large hole 21a (FIG. 4B). The front cover body 10 and the back cover body 11 are fixed by the member B.
[0014]
As described above, since the control box 1 has the front cover body 10 and the back cover body 11 fixed by the fastening members A and B, it is difficult to open the control box 1 unless the fastening member A is cut. Yes, when it opens, the trace remains and the cheating is known.
[0015]
Next, an operation of opening the control box and reassembling to inspect the “control elements such as ROM” in the control box 1 will be described (see FIG. 5).
First, the front cover body 10 and the back cover body 11 can be separated by cutting along the cut windows 17a and 17b formed in the fastening members A and B with scissors or the like. Therefore, the control element (not shown) is taken out, inspected, and attached again.
Then, the front cover body 10 and the back cover body 11 are attached to each other, but the fastening member A is cut by the cut window 17a, the end A1 is the front cover body 10, and the other end is the back cover body 11. It remains fixed with the breaking screw 16. Therefore, the fastening member A does not fix the front cover body 10 and the back cover body 11.
[0016]
On the other hand, the fastening member B is cut by the cutting window 17b and the remaining portion B1 remains in the front cover body 10, while the locking claw 20a of the cutting fastening member B ′ is not locked to the large hole 21a. By moving 20b, the cutting and fastening member B ′ can be easily pulled out from the engagement hole 21b.
Then, when the locking claws 20a and 20b formed on the cutting and fastening member B ′ are mounted in the locking holes 22a and 22b, the locking claws 20a and 20b are locked in the locking holes 22a and 22b, respectively. Since these locking claws 20a and 20b are formed in different directions, it is necessary to move them back and forth (up and down) in order to remove the cutting fastening member B '. It is difficult to remove depending on the direction of the claws 20a and 20b. Therefore, the front cover body 10 and the back cover body 11 are fixed by the cutting and fastening member B ′, and it is difficult to open unless the cutting and fastening member B ′ is cut.
[0017]
Next, as shown in FIG. 6, a modified example of the fastening members A and B is shown.
FIG. 6 (A) is a modified example of the fastening member B. The locking claws 20a, 20b formed on the fastening member B1 are composed of three pieces, and the directions of the locking claw portions 25a, 26a on both sides are as follows. Although the same as shown in FIG. 3C, the central locking claws 25b and 26b are formed in opposite directions. The engaging hole 21A is formed as a hole that cannot be locked to the locking claw 20a (locking claw portions 25a, 25b), and the engaging hole 21B is formed into the locking claw 20b (locking claw portions 26a, 26b). Therefore, when the locking claw 20b is mounted in the engagement hole 21B, the locking claw 26a, 26b formed on both sides is pulled out as compared with the locking claw 20b shown in FIG. It becomes difficult.
[0018]
FIG. 6B shows a modified example of the fastening member A. The fastening member A1 is an independent piece that does not have its end fixed to the front cover body, and has a through hole 30 formed in the end. A screw hole (not shown) is opened in the front cover body 10 at a position corresponding to the through hole 30.
