The space for interposing the rotating body is configured to change from the wide part to the narrow part in the rotational direction for tightening the screw part, and the maximum wide part is the rotating part. It is larger than the diameter of the body, and the minimum narrow width portion is smaller than the diameter of the rotating body.

請求項６に記載された発明は、請求項５に記載された発明において、前記封印ネジの回転伝達機構が、上記回転伝達機構が、上記最小幅狭部よりも、上記ネジ部の締め付け方向前方部位における回転操作部材の円筒部内周あるいは回転部材の外周のいずれか一方もしくは双方に段部を形成し、この段部を境にして上記ネジ部の締め付け方向前方部位に、回転体の直径よりも大きな空間からなる拡幅部を形成したものであることを特徴とするものである。   The invention described in claim 6 is the invention described in claim 5, wherein the rotation transmission mechanism of the sealing screw is more forward in the tightening direction of the screw portion than the minimum width narrow portion. A step portion is formed on one or both of the inner periphery of the cylindrical portion of the rotation operation member and the outer periphery of the rotation member in the region, and the screw portion is tightened in front of the screw portion in the tightening direction from the step portion. It is characterized by forming a widened portion consisting of a large space.

請求項７に記載された発明は、請求項１〜６のいずれかに記載された発明において、前記封印ネジが、上記回転部材の外周と回転操作部材の内周とのそれぞれに抜止め用突部を設け、これら抜止め用突部が、直接または間接的に引っ掛かり合い、回転操作部材が抜けて回転部材が露出するのを防止するものであることを特徴とするものである。   The invention described in claim 7 is the invention described in any one of claims 1 to 6, wherein the sealing screw is provided on each of an outer periphery of the rotating member and an inner periphery of the rotating operation member. The retaining protrusions are directly or indirectly hooked to prevent the rotation operation member from coming off and the rotation member from being exposed.

請求項１〜６に記載された遊技機の制御装置に用いられる封印ネジは、ネジ部を締める方向に回転操作部材を回すと、回転操作部材と回転部材とが一体回転してネジ部がその締め付け方向に回って締め付け対象を封印する。一方、ネジ部を緩める方向に回転操作部材を回すと、この回転操作部材が空回りするので、当該封印ネジを緩めることができない。しかも、上記回転操作部材の円筒部と覆い部によってネジ部と直結している回転部材の外周を覆うので、上記回転部材をペンチなどで直接摘んでそれを回すことはできない。したがって、当該封印ネジは、ほぼ完璧な封印機能を発揮することができる。それゆえ、当該封印ネジを利用した制御装置は、取付片を切断することなく上カバーが不正に取り外される事態を効果的に防止することができる。したがって、請求項１に記載された遊技機によれば、制御装置の内部に搭載された制御素子の不正取り替え、不正改造を効果的に防止することが可能となる。   The sealing screw used in the control device for a gaming machine according to any one of claims 1 to 6 is configured such that when the rotation operation member is rotated in a direction in which the screw portion is tightened, the rotation operation member and the rotation member rotate integrally, and the screw portion is Turn in the tightening direction and seal the object to be tightened. On the other hand, when the rotation operation member is turned in the direction of loosening the screw portion, the rotation operation member rotates idle, and thus the sealing screw cannot be loosened. Moreover, since the outer periphery of the rotating member directly connected to the screw portion is covered by the cylindrical portion and the covering portion of the rotating operation member, the rotating member cannot be directly picked with pliers or the like and turned. Therefore, the sealing screw can exhibit an almost perfect sealing function. Therefore, the control device using the sealing screw can effectively prevent the situation where the upper cover is illegally removed without cutting the attachment piece. Therefore, according to the gaming machine described in claim 1, it is possible to effectively prevent unauthorized replacement and unauthorized modification of the control element mounted in the control device.

請求項２に記載された遊技機の制御装置に用いられる封印ネジは、回転伝達機構としてコイルスプリングを用いたので、その構成を簡単にでき、そのコストを大幅に軽減させることができる。したがって、請求項１に記載された遊技機は、安価に製造することができる。   Since the sealing screw used in the control device of the gaming machine according to the second aspect uses a coil spring as the rotation transmission mechanism, the configuration can be simplified and the cost can be greatly reduced. Therefore, the gaming machine described in claim 1 can be manufactured at low cost.

請求項３に記載された遊技機の制御装置に用いられる封印ネジは、ネジ結合の締め付け力が、予め定めた設定値に達したとき、回転部材と回転操作部材とが、上記スプリングの圧接力に抗して相対回転するので、当該封印ネジを必要以上に締め付けて、そのネジ部をねじ切ったりすることができない。このように、ネジ部を緩めることもできなければ、ねじ切ったりすることもできないので、封印状態を解除できず、完璧な封印機能を発揮させることができる。それゆえ、当該封印ネジを利用した制御装置は、取付片を切断することなく上カバーが不正に取り外される事態をより効果的に防止することができる。したがって、請求項３に記載された遊技機によれば、制御装置の内部に搭載された制御素子の不正取り替え、不正改造を非常に効果的に防止することが可能となる。   The sealing screw used in the control device for a gaming machine according to claim 3 is configured such that when the tightening force of the screw connection reaches a predetermined set value, the rotating member and the rotating operation member are pressed against each other. Therefore, the sealing screw cannot be tightened more than necessary and the threaded portion cannot be threaded. As described above, since the threaded portion cannot be loosened and cannot be threaded, the sealed state cannot be released and a perfect sealing function can be exhibited. Therefore, the control device using the sealing screw can more effectively prevent the situation where the upper cover is illegally removed without cutting the attachment piece. Therefore, according to the gaming machine described in claim 3, it is possible to very effectively prevent unauthorized replacement and unauthorized modification of the control element mounted inside the control device.

請求項５に記載された遊技機の制御装置に用いられる封印ネジは、ネジ部を締め付ける方向に回転操作部材を回転させるときには、回転体が幅狭部に食い込むようになるので、回転操作部材と回転部材とが一体回転して、ネジ部を強い力で締め付けることができる。しかも、ネジ部を緩める方向に回転操作部材を回転させるときには、回転体が幅広部側に移動し、回転操作部材が回転部材に対して自由回転するので、ネジ部を緩めることができない。特に、回転体が幅狭部に食い込むので、回転操作部材の回転力が回転部材に確実に伝達されることになる。それゆえ、当該封印ネジを利用した制御装置は、取付片を切断することなく上カバーが不正に取り外される事態をより効果的に防止することができる。したがって、請求項５に記載された遊技機によれば、制御装置の内部に搭載された制御素子の不正取り替え、不正改造を非常に効果的に防止することが可能となる。   The sealing screw used in the control device for a gaming machine according to claim 5 is configured such that when the rotary operation member is rotated in a direction in which the screw portion is tightened, the rotating body bites into the narrow portion. The rotating member integrally rotates, and the screw portion can be tightened with a strong force. In addition, when the rotation operation member is rotated in the direction of loosening the screw portion, the rotating body moves to the wide portion side and the rotation operation member freely rotates with respect to the rotation member, so that the screw portion cannot be loosened. In particular, since the rotating body bites into the narrow portion, the rotational force of the rotating operation member is reliably transmitted to the rotating member. Therefore, the control device using the sealing screw can more effectively prevent the situation where the upper cover is illegally removed without cutting the attachment piece. Therefore, according to the gaming machine described in the fifth aspect, it is possible to very effectively prevent unauthorized replacement and unauthorized modification of the control element mounted inside the control device.

請求項６に記載された遊技機の制御装置に用いられる封印ネジは、ネジ結合の締め付け力が、予め定めた設定値に達したとき、回転体が段部を乗り越えて拡幅部に移動し、回転操作部材が回転部材に対して自由回転するので、当該封印ネジを必要以上に締め付けて、そのネジ部をねじ切ったりすることができない。それゆえ、当該封印ネジを利用した制御装置は、取付片を切断することなく上カバーが不正に取り外される事態をより効果的に防止することができる。したがって、請求項６に記載された遊技機によれば、制御装置の内部に搭載された制御素子の不正取り替え、不正改造を非常に効果的に防止することが可能となる。   The sealing screw used for the control device of the gaming machine according to claim 6, when the tightening force of the screw connection reaches a predetermined set value, the rotating body moves over the stepped portion and moves to the widened portion, Since the rotation operation member freely rotates with respect to the rotation member, the sealing screw cannot be tightened more than necessary and the screw portion cannot be threaded. Therefore, the control device using the sealing screw can more effectively prevent the situation where the upper cover is illegally removed without cutting the attachment piece. Therefore, according to the gaming machine described in claim 6, it is possible to very effectively prevent unauthorized replacement and unauthorized modification of the control element mounted inside the control device.

請求項７に記載された遊技機の制御装置に用いられる封印ネジは、回転操作部材と回転部材とに抜止め用突部を設けたので、回転操作部材を抜き取って回転部材を露出させ、それを回すようなこともできない。それゆえ、当該封印ネジを利用した制御装置は、取付片を切断することなく上カバーが不正に取り外される事態を一層効果的に防止することができる。したがって、請求項７に記載された遊技機によれば、制御装置の内部に搭載された制御素子の不正取り替え、不正改造をきわめて効果的に防止することが可能となる。   Since the sealing screw used for the control device of the gaming machine according to claim 7 is provided with a protrusion for preventing the rotation on the rotation operation member and the rotation member, the rotation member is extracted to expose the rotation member. You can't even turn. Therefore, the control device using the sealing screw can more effectively prevent the situation where the upper cover is illegally removed without cutting the attachment piece. Therefore, according to the gaming machine described in claim 7, it is possible to prevent tampering and tampering of the control element mounted inside the control device very effectively.

［封印ネジの構造］
図６は、封印ネジ１３を示したものであり、当該封印ネジ１３は、金属製の雄ネジ部６１とこの雄ネジ部６１の軸線上に一体に設けた金属製の回転部材６２とを備えるとともに、この回転部材６２の先端すなわち雄ネジ部６１とは反対端にフランジ部６２ａを形成している。そして、上記回転部材６２の周囲には、この発明の回転伝達機構を構成するコイルスプリング６３をはめているが、このコイルスプリング６３の内径は回転部材６２の外径よりも多少小さくして、コイルスプリング６３に圧入代を確保している。このようにしたコイルスプリング６３の上端すなわち上記フランジ部６２ａに隣接する端部には、外径方向に突出する突出部６３ａを設けている。 [Structure of sealed screw]
FIG. 6 shows the sealing screw 13, and the sealing screw 13 includes a metal male screw part 61 and a metal rotating member 62 provided integrally on the axis of the male screw part 61. In addition, a flange portion 62 a is formed at the tip of the rotating member 62, that is, the end opposite to the male screw portion 61. A coil spring 63 constituting the rotation transmission mechanism of the present invention is fitted around the rotating member 62. The inner diameter of the coil spring 63 is slightly smaller than the outer diameter of the rotating member 62, and A press-fitting allowance is secured in the spring 63. At the upper end of the coil spring 63 thus formed, that is, at the end adjacent to the flange portion 62a, a protruding portion 63a protruding in the outer diameter direction is provided.

上記のようにコイルスプリング６３を圧入した回転部材６２は、金属製の回転操作部材６４で覆うが、この回転操作部材６４は、円筒部６４ａとこの円筒部６４ａの一方の開口をふさぐ覆い部６４ｂとによって袋ナット状にしている。このようにした円筒部６４ａの内壁面には軸線に平行にした掛け止溝６４ｃを形成するとともに、この掛け止溝６４ｃの下端を円筒部６４ａの下端開口縁に開放している。そして、コイルスプリング６３を圧入した回転部材６２の上方から、回転操作部材６４をかぶせるときには、上記掛け止溝６４ｃに、コイルスプリング６３の突出部６３ａを挿入する。ただし、この突出部６３ａは、何らかの形で回転操作部材６４に固定されていればよい。   The rotary member 62 into which the coil spring 63 is press-fitted as described above is covered with a metal rotary operation member 64. The rotary operation member 64 includes a cylindrical portion 64a and a cover portion 64b that covers one opening of the cylindrical portion 64a. And is made into a cap nut shape. A retaining groove 64c parallel to the axis is formed on the inner wall surface of the cylindrical portion 64a thus configured, and the lower end of the retaining groove 64c is opened to the lower end opening edge of the cylindrical portion 64a. Then, when the rotation operation member 64 is covered from above the rotation member 62 into which the coil spring 63 is press-fitted, the protruding portion 63a of the coil spring 63 is inserted into the retaining groove 64c. However, this protrusion 63a may be fixed to the rotation operation member 64 in some form.

上記のようにして回転操作部材６４を回転部材６２にかぶせたら、回転操作部材６４の下端における開口をリングからなる抜止め用突部６５でふさぐ。この抜止め用突部６５は、その外周を円筒部６４ａの内側に圧入して固定するとともに、回転部材６２には相対回転自在にしている。そして、この抜止め用突部６５と、上記回転部材６２の抜止め用突部６２ａとの間にコイルスプリング６３が介在し、回転操作部材６４を回転部材６２から引き抜く方向の力が作用したとき、コイルスプリング６３を介して両抜止め用突部６２ａ，６５が引っ掛かり合って、回転操作部材６４を回転部材６２から抜き取るのを防止する。したがって、上記のように引き抜く方向の力が作用したとしても、抜止め用突部６５が回転操作部材６４から抜けないようにするために十分な強度が確保できれば、抜止め用突部６５は圧入で十分である。しかし、その強度を維持できないときには、たとえば、抜止め用突部６５と回転操作部材６４とを溶接したり、あるいは抜止め用突部６５と回転操作部材６４とをネジではめ合わたりしてもよい。   When the rotation operation member 64 is placed on the rotation member 62 as described above, the opening at the lower end of the rotation operation member 64 is closed by the retaining projection 65 made of a ring. The retaining projection 65 is press-fitted and fixed to the inner side of the cylindrical portion 64 a and is rotatable relative to the rotating member 62. When the coil spring 63 is interposed between the retaining protrusion 65 and the retaining protrusion 62 a of the rotating member 62, and a force in the direction of pulling the rotating operation member 64 from the rotating member 62 is applied. Further, the protrusions 62 a and 65 for retaining both are caught through the coil spring 63, and the rotation operation member 64 is prevented from being extracted from the rotation member 62. Therefore, even if a force in the pulling direction is applied as described above, the retaining protrusion 65 is press-fitted if sufficient strength can be secured to prevent the retaining protrusion 65 from coming off the rotation operation member 64. Is enough. However, when the strength cannot be maintained, for example, the retaining projection 65 and the rotation operation member 64 may be welded, or the retention projection 65 and the rotation operation member 64 may be fitted with screws. Good.

上記のようにリング部材６５をはめることによって、コイルスプリング６３が上記フランジ部６２ａとリング部材６５間に介在して、たとえば搬送時などに、回転部材６２が回転操作部材６４ から抜けるのを防止できる。なお、図中符号６６はワッシャーで、雄ネジ部６１と回転部材６２との境界部分に形成される段部に接触させるようにしている。   By fitting the ring member 65 as described above, the coil spring 63 is interposed between the flange portion 62a and the ring member 65, so that the rotation member 62 can be prevented from coming off from the rotation operation member 64 during conveyance, for example. . In addition, the code | symbol 66 is a washer in the figure, and it is made to contact the step part formed in the boundary part of the external thread part 61 and the rotation member 62. FIG.

上記のようにした封印ネジ１３を使用するときには、雄ネジ部６１をたとえばケースなどの締め付け対象の雌ネジ部にはめるとともに、回転操作部材６４を、上記雄ネジ部６１を締め付ける方向に回す。このとき、コイルスプリング６３の圧入代分の力が作用しているので、雄ネジ部６１のネジ締め付け時の回転トルクが小さければ、回転操作部材６４の回転力で雄ネジ部６１を回すことができる。雄ネジ部６１がねじ込まれてその回転トルクが大きくなれば、回転操作部材６４と、雄ネジ部６１および回転部材６２とがわずかではあるが相対回転する。このときにコイルスプリング６３はその圧入代分の力で回転部材６２側と一体回転するとともに、突出部６３ａは回転操作部材６４と一体回転する。これによって、コイルスプリング６３が縮径して回転部材６２をその縮径力で保持し、回転操作部材６４の回転力を、コイルスプリング６３および回転部材６２を介して雄ネジ部６１に伝達する。したがって、雄ネジ部６１は回転操作部材６４の強い力で締め付けられることになる。   When using the sealing screw 13 as described above, the male screw portion 61 is fitted into a female screw portion to be tightened such as a case, and the rotation operation member 64 is rotated in a direction in which the male screw portion 61 is tightened. At this time, since the force for the press-fitting allowance of the coil spring 63 is acting, if the rotational torque at the time of screw tightening of the male screw portion 61 is small, the male screw portion 61 can be rotated by the rotational force of the rotation operation member 64. it can. When the male screw portion 61 is screwed and its rotational torque increases, the rotation operation member 64, the male screw portion 61, and the rotation member 62 relatively slightly rotate. At this time, the coil spring 63 rotates integrally with the rotating member 62 side by the force of the press-fitting allowance, and the protrusion 63 a rotates integrally with the rotation operation member 64. As a result, the coil spring 63 is reduced in diameter to hold the rotating member 62 with the reduced diameter force, and the rotational force of the rotation operation member 64 is transmitted to the male screw portion 61 via the coil spring 63 and the rotating member 62. Therefore, the male screw portion 61 is tightened by the strong force of the rotation operation member 64.

上記のように雄ネジ部６１が回転操作部材６４の回転力で締め付けられて、それがネジ終端に達し、それ以上雄ネジ部６１が回転できなくなった状態で、回転操作部材６４をさらに回転させようとしたときには、回転操作部材６４の回転トルクが、コイルスプリング６３のロックトルクに打ち勝ち、コイルスプリング６３が回転部材６２と相対回転し始める。この状態では 回転操作部材６４をどのように強い力で回しても、それが空回転することになる。したがって、回転操作部材６４を強く回しても雄ネジ部６１がねじ切れたりしない。   As described above, the male screw portion 61 is tightened by the rotational force of the rotary operation member 64, reaches the screw terminal end, and the male screw portion 61 cannot be rotated any further. When trying to do so, the rotational torque of the rotational operation member 64 overcomes the lock torque of the coil spring 63, and the coil spring 63 starts to rotate relative to the rotational member 62. In this state, no matter how strong the rotation operation member 64 is rotated, it will idle. Therefore, even if the rotation operation member 64 is rotated strongly, the male screw portion 61 is not broken.

上記のように回転操作部材６４が空回転するためには、上記ロックトルクの大きさを設定値内に収める必要があるが、このロックトルクの大きさは、次の式で表すことができる。
ＴＬ＝（ＥＩδ／ＲＡ ２）×ｅ２πμＮ−１） ・・・・・・・ （１）
ＴＳ＝（ＥＩδ／ＲＡ ２）×｛１−（１／ｅ２πμＮ）｝ ・・・・ （２）
上記（１）式のＴＬはロックトルクであり、（２）式のＴＳはスリップトルクである。また、上記両式の記号は、次のとおりである。
Ｅ・・・・コイルスプリングの縦弾性係数
Ｉ・・・・コイルスプリングの断面２次モーメント
δ・・・・コイルスプリングの圧入代
ＲＡ・・・・コイルスプリングが嵌合する回転部材の半径
μ・・・・コイルスプリングと回転部材との間の摩擦係数
Ｎ・・・・コイルスプリングの有効巻き数 In order for the rotation operation member 64 to idle, as described above, it is necessary to keep the magnitude of the lock torque within a set value. The magnitude of the lock torque can be expressed by the following equation.
T L = (EIδ / R A 2 ) × e 2πμN −1) (1)
T S = (EI δ / R A 2 ) × {1− (1 / e 2π μN )} (2)
T L in the above equation (1) is a lock torque, and T S in the equation (2) is a slip torque. Moreover, the symbols of both the above formulas are as follows.
E ··· Longitudinal elastic modulus of coil spring I ···· Secondary moment of section of coil spring δ ··· Press-fit allowance of coil spring R A ··· Radius of rotating member with which coil spring is fitted µ .... Coefficient of friction N between coil spring and rotating member ... Effective number of turns of coil spring

したがって、回転操作部材６４を締め付け方向に回転して雄ネジ部６１に作用させる最大トルクは、上記ロックトルクＴＬによって決めればよいことになる。また、ネジ結合の締め付け力が、予め定めた設定値に達したとき、回転部材と回転操作部材とが、上記スプリングの圧接力に抗して相対回転するといったときの設定値は、スリップトルクＴＳによって決めることができる。いずれにしても、上記ロックトルクおよびスリップトルクは、コイルスプリング６３の特性および回転部材６２の材質に応じて決まる相対的なものである。 Therefore, the maximum torque for rotating the rotation operation member 64 in the tightening direction and acting on the male screw portion 61 may be determined by the lock torque TL . Further, when the tightening force of the screw connection reaches a predetermined set value, the set value when the rotation member and the rotation operation member rotate relative to the pressure contact force of the spring is the slip torque T It can be determined by S. In any case, the lock torque and the slip torque are relative values determined according to the characteristics of the coil spring 63 and the material of the rotating member 62.

また、雄ネジ部６１を締める方向に回転操作部材６４を回転させたとき、コイルスプリング６３の内径が縮径する条件は、コイルスプリング６３の巻き方向が雄ネジ部６１のつる巻き線の方向と同じで、しかも、上記突出部６３ａがコイルスプリング６３の上端において外側に突出していることである。ただし、コイルスプリング１の巻き方向を雄ネジ部６１のつる巻き線の方向と逆にしたときには、上記突出部６３ａをコイルスプリング６３の下端に位置させればよい。したがって、上記突出部６３ａの位置関係も相対的なものとなる。   Further, when the rotation operation member 64 is rotated in the direction in which the male screw portion 61 is tightened, the condition that the inner diameter of the coil spring 63 is reduced is that the winding direction of the coil spring 63 is the direction of the winding of the male screw portion 61. In addition, the protrusion 63 a protrudes outward at the upper end of the coil spring 63. However, when the winding direction of the coil spring 1 is reversed from the direction of the helical winding of the male screw portion 61, the protrusion 63a may be positioned at the lower end of the coil spring 63. Therefore, the positional relationship of the protrusion 63a is also relative.

上記のように回転操作部材６４を回して雄ネジ部６１を完全に締め付けたとき、回転操作部材６４の円筒部６４ａおよび覆い部６４ｂで、回転部材６２の外周ほぼ全域が覆われる。もし、回転部材６２が露出していれば、この回転部材６２の露出している部分をペンチなどの工具を使って回すことができてしまう。したがって、回転部材６２の外周ほぼ全域を覆うとは、ペンチなどの工具を利用して回転部材６２を直接回すことができないようにすることであって、必ずしも全域を完全に覆わなくてもよい。   As described above, when the rotation operation member 64 is rotated and the male screw portion 61 is completely tightened, the entire outer periphery of the rotation member 62 is covered with the cylindrical portion 64a and the cover portion 64b of the rotation operation member 64. If the rotating member 62 is exposed, the exposed portion of the rotating member 62 can be turned using a tool such as pliers. Therefore, covering almost the entire outer periphery of the rotating member 62 means that the rotating member 62 cannot be directly rotated using a tool such as pliers, and the entire region does not necessarily have to be completely covered.

さらに、上記回転操作部材６４は、それが破壊されないようにするために、金属製であることが望ましいが、破壊されないだけの強度を維持できるなら、特に、その材質は問わない。また、雄ネジ部６１および回転部材６２の材質も、締め付け対象との相対的な関係において一定の強度を維持できれば、その材質は問わない。   Further, the rotational operation member 64 is preferably made of metal in order to prevent it from being destroyed. However, the material of the rotation operation member 64 is not particularly limited as long as the strength can be maintained without being destroyed. Moreover, the material of the external thread part 61 and the rotation member 62 will not be ask | required if a fixed intensity | strength can be maintained in the relative relationship with the clamping | tightening object.

上記の如く、ワンウェイクラッチ機構を利用した封印ネジ１３は、回転操作部材６４を時計回りに回転させた場合には、その回転力が雄ネジ部６１に伝達されて雄ネジ部６１が回転し、回転操作部材６４を反時計回りに回転させた場合には、その回転力が雄ネジ部６１に伝達されず、雄ネジ部６１が回転しない状態を保持する。   As described above, when the rotation operation member 64 is rotated clockwise, the sealing screw 13 using the one-way clutch mechanism is transmitted to the male screw portion 61 and the male screw portion 61 rotates. When the rotation operation member 64 is rotated counterclockwise, the rotational force is not transmitted to the male screw portion 61, and the state where the male screw portion 61 does not rotate is maintained.

［遊技機に設置された制御装置の作動内容］
上記の如くパチンコ機８１の裏面側の機構板に設置された制御装置１は、搭載されたＲＯＭ８やＣＰＵ等の種々の制御素子によって、パチンコ機の作動内容を制御する。 [Operation details of the control device installed in the gaming machine]
As described above, the control device 1 installed on the mechanism plate on the back surface side of the pachinko machine 81 controls the operation content of the pachinko machine by various control elements such as the ROM 8 and CPU mounted therein.

そして、上カバー６のネジ保持部９，９と下カバー５のネジ係合体２０，２０とが、ワンウェイクラッチ機構を備え、かつ、ワンウェイタイプのネジ突起７，７を設けた封印ネジ１３，１３によって螺着されているため、封印ネジ１３，１３を螺着時と反対方向（左回り）に回転させることができず、ネジ保持部９とネジ係合体２０との螺着状態を解除することができない。それゆえ、上カバー６を取り外す場合には、ネジ係合体２０，２０と螺着したネジ保持部９，９の前方に設けられた２つの取付片１０，１０・・を、ニッパ等の工具で切断し、かかるネジ保持部９，９を上カバー６から切り離すことによって、上カバー６と下カバー５とを分離しなければならない。   The screw holding portions 9 and 9 of the upper cover 6 and the screw engaging bodies 20 and 20 of the lower cover 5 are provided with a one-way clutch mechanism, and sealing screws 13 and 13 provided with one-way type screw projections 7 and 7. Since the sealing screws 13 and 13 cannot be rotated in the opposite direction (counterclockwise) to the time of screwing, the screw holding portion 9 and the screw engaging body 20 are released from the screwed state. I can't. Therefore, when the upper cover 6 is to be removed, the two attachment pieces 10, 10... Provided in front of the screw holding portions 9, 9 screwed to the screw engaging bodies 20, 20 can be removed with a tool such as a nipper. The upper cover 6 and the lower cover 5 must be separated by cutting and separating the screw holding portions 9 and 9 from the upper cover 6.

また、再度 上カバー６を下カバー５に合着させる場合には、左側の最上方のネジ係合体２０および右側の最下方のネジ保持部９以外のネジ保持部９，９（すなわち、未だネジ係合体２０と螺着していない同じ番号を付したネジ保持部９，９同士）を、それぞれ、封印ネジ１３，１３により同位置のネジ係合体２０，２０と螺着すれば良い。それゆえ、一旦、上カバー６と下カバー５とを分離した後でも、再度、上カバー６を下カバー５に合着させることができ、そのような上カバー６、下カバー５の分離、合着を４回繰り返すことができる。   When the upper cover 6 is reattached to the lower cover 5, the screw holding portions 9 and 9 other than the left uppermost screw engaging body 20 and the rightmost lowermost screw holding portion 9 (that is, still screw The screw holding portions 9 and 9 having the same numbers that are not screwed to the engaging body 20 may be screwed to the screw engaging bodies 20 and 20 at the same position by the sealing screws 13 and 13, respectively. Therefore, even after the upper cover 6 and the lower cover 5 are once separated, the upper cover 6 can be attached to the lower cover 5 again. Wearing can be repeated four times.

制御装置１は、上記の如く、上カバー６を下カバー５と分離するためには、取付片１０，１０・・を切断することによりネジ係合体２０，２０と螺着されたネジ保持部９，９を上カバー６から切り離さなければならないため、上カバー６が取り外された場合には、必ずその痕跡が残る。それゆえ、上カバー６の開閉の有無を容易に把握することができる。それにも拘わらず、各取付片１０，１０が容易に切断可能な構造を有しているため、それらの取付片１０，１０をニッパ等の工具で切断することによって、上カバー６を容易に取り外して、基板８上に設置された制御素子の内容をチェックすることができる。   As described above, in order to separate the upper cover 6 from the lower cover 5, the control device 1 cuts the attachment pieces 10, 10... So as to be screwed to the screw engaging bodies 20, 20. , 9 must be separated from the upper cover 6, so that the trace remains whenever the upper cover 6 is removed. Therefore, it is possible to easily grasp whether the upper cover 6 is opened or closed. Nevertheless, since the mounting pieces 10 and 10 have a structure that can be easily cut, the upper cover 6 can be easily removed by cutting the mounting pieces 10 and 10 with a tool such as a nipper. Thus, the contents of the control elements installed on the substrate 8 can be checked.

［パチンコ機の効果］
パチンコ機８１の制御装置１に用いられる封印ネジ１３は、ネジ部（雄ネジ部６１）を有する回転部材６２の内周または外周に、円筒部６４ａとこの円筒部６４ａの一方の開口をふさぐ覆い部６４ｂとを有する回転操作部材６４を設け、この回転操作部材６４で、上記回転部材６２の外周および上方を覆う一方、回転部材６２と回転操作部材６４との間に、上記ネジ部を締め付ける方向にはそれら回転部材６２と回転操作部材６４とを一体回転させ、上記ネジ部を緩める方向にはそれら回転部材６２と回転操作部材６４とを自由回転させる回転伝達機構（ワンウェイクラッチ機構）を設けたものである。それゆえ、ネジ部を締める方向に回転操作部材６４を回すと、回転操作部材６４と回転部材６２とが一体回転してネジ部がその締め付け方向に回って締め付け対象を封印する。一方、ネジ部を緩める方向に回転操作部材６４を回すと、この回転操作部材６４が空回りするので、当該封印ネジ１３を緩めることができない。しかも、上記回転操作部材６４の円筒部６４ａと覆い部６４ｂによってネジ部と直結している回転部材６２の外周を覆うので、上記回転部材６２をペンチなどで直接摘んでそれを回すことはできない。また、接着剤によってドライバ等の工具を封印ネジのヘッド部に固着させて当該ヘッド部を緩める方向に回転させても、当該封印ネジを取り外すことができない。したがって、当該封印ネジ１３は、ほぼ完璧な封印機能を発揮することができる。それゆえ、当該封印ネジ１３を利用した制御装置１は、取付片１０，１０・・を切断することなく上カバー６が不正に取り外される事態を効果的に防止することができる。したがって、パチンコ機８１によれば、制御装置１の内部に搭載されたＲＯＭ８の不正取り替え、不正改造を効果的に防止することができる。 [Effect of pachinko machine]
The sealing screw 13 used in the control device 1 of the pachinko machine 81 covers the cylindrical portion 64a and one opening of the cylindrical portion 64a on the inner or outer periphery of the rotating member 62 having a screw portion (male screw portion 61). A rotation operation member 64 having a portion 64 b is provided, and the rotation operation member 64 covers the outer periphery and the upper side of the rotation member 62, while tightening the screw portion between the rotation member 62 and the rotation operation member 64. Is provided with a rotation transmission mechanism (one-way clutch mechanism) that rotates the rotation member 62 and the rotation operation member 64 integrally and freely rotates the rotation member 62 and the rotation operation member 64 in the direction of loosening the screw portion. Is. Therefore, when the rotation operation member 64 is rotated in the direction in which the screw portion is tightened, the rotation operation member 64 and the rotation member 62 rotate together, and the screw portion rotates in the tightening direction to seal the object to be tightened. On the other hand, when the rotation operation member 64 is rotated in the direction of loosening the screw portion, the rotation operation member 64 rotates idle, and thus the sealing screw 13 cannot be loosened. Moreover, since the outer periphery of the rotating member 62 directly connected to the screw portion is covered by the cylindrical portion 64a and the covering portion 64b of the rotating operation member 64, the rotating member 62 cannot be directly picked with pliers or the like and turned. Further, even if a tool such as a driver is fixed to the head portion of the sealing screw with an adhesive and is rotated in the direction of loosening the head portion, the sealing screw cannot be removed. Therefore, the sealing screw 13 can exhibit a substantially perfect sealing function. Therefore, the control device 1 using the sealing screw 13 can effectively prevent a situation in which the upper cover 6 is illegally removed without cutting the attachment pieces 10, 10. Therefore, according to the pachinko machine 81, unauthorized replacement and unauthorized modification of the ROM 8 mounted inside the control device 1 can be effectively prevented.

また、封印ネジ１３は、回転伝達機構が、上記回転部材６２と回転操作部材６４との間に介在させたコイルスプリング６３からなり、このコイルスプリング６３の一端を上記回転部材６２あるいは回転操作部材６４のいずれか一方に止め、上記ネジ部を締め付ける方向に回転操作部材６４を回転させたときコイルスプリング６３のコイル径を縮径もしくは拡径して、コイルスプリング６３の内周もしくは外周を回転部材６２または回転操作部材６４に圧接し、これら回転部材６２と回転操作部材６４とを一体回転させる一方、上記回転操作部材６４を、上記ネジ部を緩める方向に回転させたとき、上記コイルスプリング６３の圧接力を小さくして、回転部材６２と回転操作部材６４とを相対回転するものである。したがって、請求項１に記載された遊技機は、封印ネジ１３の回転伝達機構の構成が簡単であり、封印ネジ１３の製造コストが低いため、安価に製造することができる。   The sealing screw 13 includes a coil spring 63 having a rotation transmission mechanism interposed between the rotation member 62 and the rotation operation member 64, and one end of the coil spring 63 is connected to the rotation member 62 or the rotation operation member 64. When the rotation operation member 64 is rotated in the direction in which the screw portion is tightened, the coil diameter of the coil spring 63 is reduced or increased, and the inner periphery or outer periphery of the coil spring 63 is set to the rotation member 62. Alternatively, when the rotary operation member 64 is rotated in the direction of loosening the screw portion while the rotary member 62 and the rotary operation member 64 are integrally rotated while being pressed against the rotary operation member 64, the coil spring 63 is pressed. The force is reduced and the rotating member 62 and the rotating operation member 64 are relatively rotated. Therefore, the gaming machine described in claim 1 can be manufactured at low cost because the structure of the rotation transmission mechanism of the sealing screw 13 is simple and the manufacturing cost of the sealing screw 13 is low.

さらに、封印ネジ１３は、上記ネジ部を締め付け対象にネジ結合させるとともに、ネジ部を締め付ける方向に回転操作部材６４を回転したときのネジ結合の締め付け力が、予め定めた設定値に達した場合に、回転部材６２と回転操作部材６４とが、上記コイルスプリング６３の圧接力に抗して相対回転するものである。それゆえ、封印ネジ１３を必要以上に締め付けて、そのネジ部をねじ切ったりすることができない。このように、ネジ部を緩めることもできなければ、ねじ切ったりすることもできないので、封印状態を解除できず、完璧な封印機能を発揮させることができる。それゆえ、当該封印ネジ１３を利用した制御装置１は、取付片１０，１０・・を切断することなく上カバー６が不正に取り外される事態をより効果的に防止することができる。したがって、パチンコ機８１によれば、制御装置１の内部に搭載されたＲＯＭ８の不正取り替え、不正改造を非常に効果的に防止することができる。   Further, when the sealing screw 13 is screw-coupled to the tightening target and the rotational force of the rotating operation member 64 is rotated in the direction of tightening the screw part, the screwing tightening force reaches a predetermined set value. In addition, the rotation member 62 and the rotation operation member 64 rotate relative to each other against the pressure contact force of the coil spring 63. Therefore, the sealing screw 13 cannot be tightened more than necessary and the threaded portion cannot be threaded. As described above, since the threaded portion cannot be loosened and cannot be threaded, the sealed state cannot be released and a perfect sealing function can be exhibited. Therefore, the control device 1 using the sealing screw 13 can more effectively prevent a situation in which the upper cover 6 is illegally removed without cutting the attachment pieces 10, 10. Therefore, according to the pachinko machine 81, unauthorized replacement and unauthorized modification of the ROM 8 mounted inside the control device 1 can be prevented very effectively.

加えて、封印ネジ１３は、上記回転部材６２の外周と回転操作部材６４の内周とのそれぞれに抜止め用突部６２ａ，６５を設け、これら抜止め用突部６２ａ，６５が、直接または間接的に引っ掛かり合い、回転操作部材６４が抜けて回転部材６２が露出するのを防止するものである。それゆえ、封印ネジ１３によれば、回転操作部材６４を抜き取って回転部材６２を露出させ、それを回すようなこともできない。それゆえ、当該封印ネジ１３を利用した制御装置１は、取付片１０，１０・・を切断することなく上カバー６が不正に取り外される事態を一層効果的に防止することができる。したがって、パチンコ機８１によれば、制御装置１の内部に搭載されたＲＯＭ８の不正取り替え、不正改造をきわめて効果的に防止することができる。   In addition, the sealing screw 13 is provided with retaining protrusions 62a and 65 on the outer periphery of the rotating member 62 and the inner periphery of the rotating operation member 64, respectively. It indirectly catches and prevents the rotation operation member 64 from coming off and the rotation member 62 from being exposed. Therefore, according to the sealing screw 13, it is not possible to extract the rotation operation member 64 to expose the rotation member 62 and rotate it. Therefore, the control device 1 using the sealing screw 13 can more effectively prevent a situation in which the upper cover 6 is illegally removed without cutting the attachment pieces 10, 10. Therefore, according to the pachinko machine 81, unauthorized replacement and unauthorized modification of the ROM 8 mounted in the control device 1 can be prevented very effectively.

［遊技機の変更例］
なお、本発明の遊技機の構成は、上記実施形態の態様に何ら限定されるものではなく、制御装置（基板、上カバー、下カバー、ワンウェイタイプの封印ネジ等）の形状、構造等の構成を本発明の趣旨を逸脱しない範囲内で適宜変更することができる。 [Examples of game machine changes]
Note that the configuration of the gaming machine of the present invention is not limited to the aspect of the above embodiment, and the configuration, configuration, etc., of the control device (substrate, upper cover, lower cover, one-way type sealing screw, etc.) Can be changed as appropriate without departing from the spirit of the present invention.

たとえば、制御装置の上カバーの各上固着翼に設けるネジ保持部の個数や、下カバーの左右の各下固着翼に設ける取付タブの個数は、４個に限定されず、３個以下あるいは５個以上でも良い。また、各上固着翼とネジ保持部とを連結する取付片の個数も、２個に限定されず、１個でも良いし、３個以上でも良い。さらに、上固着翼や下固着翼の設置位置は、上下カバーの左右両端縁に限定されず、上下カバーの上下両端縁でも良い。   For example, the number of screw holding portions provided on each upper fixing wing of the upper cover of the control device and the number of mounting tabs provided on each of the lower fixing wings on the left and right of the lower cover are not limited to four, but three or less or five. It may be more than one. Further, the number of attachment pieces for connecting each upper fixing blade and the screw holding portion is not limited to two, and may be one or three or more. Furthermore, the installation positions of the upper fixing wing and the lower fixing wing are not limited to the left and right end edges of the upper and lower covers, but may be the upper and lower end edges of the upper and lower covers.

また、ワンウェイタイプの封印ネジは、上記実施形態の如く、回転部材の周囲に設けられたコイルスプリングの一端を回転操作部材の内面に止めたものに限定されず、雄ネジ部、回転部材、コイルスプリング、回転操作部材、リング部材、ワッシャー等の形状、構造等の構成を必要に応じて適宜変更することができる。   Further, the one-way type sealing screw is not limited to the one in which one end of the coil spring provided around the rotating member is fixed to the inner surface of the rotating operation member as in the above embodiment, but the male screw portion, the rotating member, the coil The configuration of the shape, structure, etc. of the spring, the rotation operation member, the ring member, the washer, etc. can be appropriately changed as necessary.

図７は、封印ネジの変更例を示したものであり、この封印ネジ５１は、この発明の回転伝達機構を構成するコイルスプリング６３を回転操作部材６４の内側に、一定の圧入代をもってはめ込み、回転操作部材６４を回転させたとき、当該コイルスプリング６３が拡径するようにしたもので、以下にはさらに詳しく説明する。この封印ネジ５１の回転部材６２の外側には、軸線に平行にした掛け止溝６２ｂを形成するとともに、この掛け止溝６２ｂの下端を回転部材６２の下端に開放している。一方、コイルスプリング６３は、その外径を回転操作部材６４の内径よりも多少大きくして、コイルスプリング６３に圧入代を確保している。このようにしたコイルスプリング６３の上端すなわち上記抜止め用突部６２ａに隣接する端部には、内径方向に突出する突出部６３ａを設けている。   FIG. 7 shows a modified example of the sealing screw. This sealing screw 51 is fitted with the coil spring 63 constituting the rotation transmission mechanism of the present invention inside the rotation operation member 64 with a certain press-fitting allowance, When the rotary operation member 64 is rotated, the coil spring 63 expands in diameter, and will be described in more detail below. A retaining groove 62 b that is parallel to the axis is formed outside the rotating member 62 of the sealing screw 51, and the lower end of the retaining groove 62 b is open to the lower end of the rotating member 62. On the other hand, the outer diameter of the coil spring 63 is slightly larger than the inner diameter of the rotation operation member 64 to secure a press-fitting allowance for the coil spring 63. A protrusion 63a protruding in the inner diameter direction is provided at the upper end of the coil spring 63 thus configured, that is, at an end adjacent to the retaining protrusion 62a.

そして、上記回転部材６２に回転操作部材６４をかぶせるときには、まず、ワッシャー６６を外した状態で、コイルスプリング６３に回転部材６２を挿入するが、このときには上記突出部６３ａを掛け止溝６２ｂに挿入する。次に、コイルスプリング６３の下端、すなわち突出部６３ａとは反対端をペンチなどで摘んで、このコイルスプリング６３を縮径する方向に回すとともに、この縮径状態を保ったまま、回転操作部材６４を回転部材６２の上からかぶせる。回転操作部材６４を上記のようにしてかぶせたら、コイルスプリング６３の縮径力を開放する。縮径力を開放されたコイルスプリング６３は、その外周を回転操作部材６４の内壁面に圧接させる。つまり、コイルスプリング６３は回転操作部材６４に対して所定の圧入代を確保した状態で圧入された状態を保つ。なお、図７中、符号６１は雄ネジ部、６２ａはフランジからなる抜止め用突部、６４ａは円筒部、６４ｂは覆い部、６５はリングからなる抜止め用突部であって、それらは上記実施形態の封印ネジ１３と全く同様に機能するものである。   When the rotation operation member 64 is put on the rotation member 62, first, the rotation member 62 is inserted into the coil spring 63 with the washer 66 removed. At this time, the protrusion 63a is inserted into the latching groove 62b. To do. Next, the lower end of the coil spring 63, that is, the end opposite to the protruding portion 63a is picked with pliers or the like, and the coil spring 63 is rotated in the direction of reducing the diameter, and the rotating operation member 64 is maintained while maintaining the reduced diameter state. Is put on the rotating member 62. When the rotation operation member 64 is covered as described above, the diameter reducing force of the coil spring 63 is released. The coil spring 63 whose diameter reducing force is released presses the outer periphery thereof against the inner wall surface of the rotation operation member 64. That is, the coil spring 63 keeps being pressed into the rotational operation member 64 in a state where a predetermined press-fitting allowance is secured. In FIG. 7, reference numeral 61 is a male threaded portion, 62a is a retaining projection made of a flange, 64a is a cylindrical portion, 64b is a covering portion, and 65 is a retaining projection made of a ring. It functions in exactly the same way as the sealing screw 13 of the above embodiment.

上記のようにした封印ネジ５１を使用するときには、上記実施形態の場合と同様に、回転操作部材６４を、上記雄ネジ部６１を締め付ける方向に回す。このとき、コイルスプリング６３の圧入代分の力が作用しているので、雄ネジ部６１の回転トルクが小さければ、回転操作部材６４の回転力で雄ネジ部６１を回すことができる。雄ネジ部６１がねじ込まれてその回転トルクが大きくなれば、回転操作部材６４と、雄ネジ部６１および回転部材６２とがわずかではあるが相対回転する。このときにコイルスプリング６３はその圧入代分の力で回転操作部材６４側と一体回転するとともに、突出部６３ａは回転部材６２と一体回転する。これによって、コイルスプリング６３が拡径して、回転操作部材６４をその拡径力で保持し、回転操作部材６４の回転力を、コイルスプリング６３および回転部材６２を介して雄ネジ部６１に伝達する。したがって、雄ネジ部６１は回転操作部材６４の強い力で締め付けられることになる。   When using the sealing screw 51 as described above, the rotation operation member 64 is rotated in the direction in which the male screw portion 61 is tightened, as in the case of the above embodiment. At this time, since the force for the press-fitting allowance of the coil spring 63 is acting, if the rotational torque of the male screw portion 61 is small, the male screw portion 61 can be rotated by the rotational force of the rotary operation member 64. When the male screw portion 61 is screwed and its rotational torque increases, the rotation operation member 64, the male screw portion 61, and the rotation member 62 relatively slightly rotate. At this time, the coil spring 63 rotates integrally with the rotation operation member 64 side by the force of the press-fitting allowance, and the protrusion 63 a rotates integrally with the rotation member 62. As a result, the diameter of the coil spring 63 is increased, the rotation operation member 64 is held by the increased diameter force, and the rotation force of the rotation operation member 64 is transmitted to the male screw portion 61 via the coil spring 63 and the rotation member 62. To do. Therefore, the male screw portion 61 is tightened by the strong force of the rotation operation member 64.

上記のように雄ネジ部６１が回転操作部材６４の回転力で締め付けられて、それがネジ終端に達し、それ以上雄ネジ部６１が回転できなくなった状態で、回転操作部材６４をさらに回転させようとしたときには、回転操作部材６４の回転トルクが、コイルスプリング６３のロックトルクに打ち勝ち、コイルスプリング６３が回転操作部材６４と相対回転し始める。この状態では、回転操作部材６４をどのように強い力で回しても、それが空回転することになる。上記以外の構成および作用効果は、上記実施形態の封印ネジ１３と全て同じである。また、コイルスプリング６３の巻き方向や突出部６３ａの位置、および各部材の材質に関しても上記実施形態の封印ネジ１３について説明したことと同じである。   As described above, the male screw portion 61 is tightened by the rotational force of the rotary operation member 64, reaches the screw terminal end, and the male screw portion 61 cannot be rotated any further. When trying to do so, the rotational torque of the rotation operation member 64 overcomes the lock torque of the coil spring 63, and the coil spring 63 starts to rotate relative to the rotation operation member 64. In this state, no matter how strong the rotation operation member 64 is rotated, it rotates idly. Other configurations and operational effects are the same as those of the sealing screw 13 of the above embodiment. Further, the winding direction of the coil spring 63, the position of the protrusion 63a, and the material of each member are the same as those described for the sealing screw 13 of the above embodiment.

図８は、封印ネジの別の変更例を示したものであり、この封印ネジ５２の雄ネジ部６１に一体に設けた回転部材６２は、上方に向けて開口する凹部６２ｃを形成するとともに、この凹部６２ｃの内面には、軸線に平行な掛け止溝６２ｂを形成している。一方、回転操作部材６４は円筒部６４ａおよび覆い部６４ｂを形成するとともに、この円筒部６４ａの内側に雄ネジ部６１と軸心を同じにした円柱部６４ｄを形成している。そして、上記円柱部６４ｄに、この発明の回転伝達機構を構成するコイルスプリング６３を前記したと同様の圧入代を確保してはめるとともに、このコイルスプリング６３の下端に外径方向に突出させた突出部６３ａを設け、この突出部６３ａを上記掛け止溝６２ｂに挿入している。   FIG. 8 shows another modified example of the sealing screw. The rotating member 62 provided integrally with the male screw portion 61 of the sealing screw 52 forms a concave portion 62c that opens upward, A retaining groove 62b parallel to the axis is formed on the inner surface of the recess 62c. On the other hand, the rotation operation member 64 forms a cylindrical part 64a and a cover part 64b, and forms a cylindrical part 64d having the same axial center as the male screw part 61 inside the cylindrical part 64a. Then, the coil spring 63 constituting the rotation transmission mechanism of the present invention is fitted to the cylindrical portion 64d with the same press-fitting allowance as described above, and the protrusion protruded in the outer diameter direction at the lower end of the coil spring 63. A portion 63a is provided, and the protruding portion 63a is inserted into the retaining groove 62b.

なお、図８中、６１は雄ネジ部、６５はリングからなる抜止め用突部、６６はワッシャー、６７は回転部材６２の下端に設けた段部からなる抜止め用突部であって、それらは上記実施形態の封印ネジ１３と全く同様に機能するものである。このようにした封印ネジ５２においては、雄ネジ部６１を締める方向に回転操作部材６４を回したとき、コイルスプリング６３は縮径するものである。なお、上記以外の構成および作用効果は、上記実施形態の封印ネジ１３と全て同じである。また、コイルスプリング６３の巻き方向や突出部６３ａの位置、および各部材の材質に関しても上記実施形態の封印ネジ１３について説明したことと同じである。   In FIG. 8, 61 is a male screw portion, 65 is a retaining projection made of a ring, 66 is a washer, and 67 is a retaining projection made of a step provided at the lower end of the rotating member 62. They function in exactly the same way as the sealing screw 13 of the above embodiment. In the sealing screw 52 thus configured, the coil spring 63 is reduced in diameter when the rotation operation member 64 is rotated in a direction in which the male screw portion 61 is tightened. In addition, all the configurations and operational effects other than those described above are the same as those of the sealing screw 13 of the above embodiment. Further, the winding direction of the coil spring 63, the position of the protrusion 63a, and the material of each member are the same as those described for the sealing screw 13 of the above embodiment.

図９は、封印ネジの別の変更例を示したものであり、この封印ネジ５３の雄ネジ部６１に一体に設けた回転部材６２は、上方に向けて開口する凹部６２ｃを形成している。一方、回転操作部材６４は円筒部６４ａを形成するとともに、この円筒部６４ａの内側に雄ネジ部６１と軸心を同じにした円柱部６４ｄを形成している。そして、上記円柱部６４ｄの外側には軸線に平行な掛け止溝６４ｃを形成している。また、上記凹部６２ｃには、この発明の回転伝達機構を構成するコイルスプリング６３をはめるが、このコイルスプリング６３には、前記したと同様の圧入代を確保して、その外周を凹部６２ｃの内壁に圧接させるとともに、このコイルスプリング６３の下端に内径方向に突出させた突出部６３ａを設け、この突出部６３ａを上記掛け止溝６４ｃに挿入している。   FIG. 9 shows another modified example of the sealing screw, and the rotating member 62 provided integrally with the male screw portion 61 of the sealing screw 53 forms a concave portion 62c that opens upward. . On the other hand, the rotation operation member 64 forms a cylindrical portion 64a, and forms a cylindrical portion 64d having the same axial center as the male screw portion 61 inside the cylindrical portion 64a. A retaining groove 64c parallel to the axis is formed outside the cylindrical portion 64d. The recess 62c is fitted with a coil spring 63 that constitutes the rotation transmission mechanism of the present invention. The coil spring 63 has a press-fitting allowance similar to that described above, and its outer periphery is provided on the inner wall of the recess 62c. And a projecting portion 63a projecting in the inner diameter direction is provided at the lower end of the coil spring 63, and the projecting portion 63a is inserted into the retaining groove 64c.

なお、図９中、６１は雄ネジ部、６５はリングからなる抜止め用突部、６６はワッシャー、６７は回転部材６２の下端に設けた段部からなる抜止め用突部であって、それらは上記実施形態の封印ネジ１３と全く同様に機能するものである。このようにした封印ネジ５３においては、雄ネジ部６１を締める方向に回転操作部材６４を回したとき、コイルスプリング６３は拡径するものである。なお、上記以外の構成および作用効果は、上記実施形態の封印ネジ１３と全て同じである。また、コイルスプリング６３の巻き方向や突出部６３ａの位置、および各部材の材質に関しても上記実施形態の封印ネジ１３について説明したことと同じである。   In FIG. 9, 61 is a male screw part, 65 is a retaining protrusion made of a ring, 66 is a washer, and 67 is a retaining protrusion made of a step provided at the lower end of the rotating member 62. They function in exactly the same way as the sealing screw 13 of the above embodiment. In the sealing screw 53 configured as described above, when the rotation operation member 64 is rotated in the direction in which the male screw portion 61 is tightened, the coil spring 63 is expanded in diameter. In addition, all the configurations and operational effects other than those described above are the same as those of the sealing screw 13 of the above embodiment. Further, the winding direction of the coil spring 63, the position of the protrusion 63a, and the material of each member are the same as those described for the sealing screw 13 of the above embodiment.

図１０は、封印ネジの別の変更例を示したものであり、この封印ネジ５４は、雌ネジ部６８と回転部材６９とを一体化したものである。言い換えると、回転部材６９に雌ネジ部６８を形成したものである。そして、回転部材６９とコイルスプリング６３および回転操作部材６４との関係は、上記実施形態の封印ネジ１３と全く同じである。加えて、コイルスプリング６３がこの発明の回転伝達機構を構成することも上記実施形態と同様である。また、封印ネジ５４は、上記実施形態の封印ネジ１３における雄ネジ部６１の代わりに、これを雌ネジ部６８としたものであるが、前記した封印ネジ５１〜５３のそれぞれについても、その雄ネジ部６１に代えて雌ネジ部としてもよいものである。   FIG. 10 shows another modified example of the sealing screw, and this sealing screw 54 is obtained by integrating a female screw portion 68 and a rotating member 69. In other words, the internal thread portion 68 is formed on the rotating member 69. The relationship between the rotation member 69, the coil spring 63, and the rotation operation member 64 is exactly the same as that of the sealing screw 13 of the above embodiment. In addition, the coil spring 63 constitutes the rotation transmission mechanism of the present invention as in the above embodiment. In addition, the sealing screw 54 is a female screw portion 68 instead of the male screw portion 61 in the sealing screw 13 of the above embodiment, but each of the sealing screws 51 to 53 described above also has its male screw portion. Instead of the screw part 61, a female screw part may be used.

なお、図１０中、６３ａは突出部、６４ａは円筒部、６４ｂは覆い部、６４ｃは掛け止溝、６５はリングからなる抜止め用突部、６９ａはフランジからなる抜止め用突部であって、それらは上記実施形態の封印ネジ１３と全く同様に機能するものである。また、上記以外の構成および作用効果は、上記実施形態の封印ネジ１３と全て同じである。また、コイルスプリング６３の巻き方向や突出部６３ａの位置、および各部材の材質に関しても上記実施形態の封印ネジ１３について説明したことと同じである。   In FIG. 10, 63a is a projecting portion, 64a is a cylindrical portion, 64b is a covering portion, 64c is a retaining groove, 65 is a retaining projection made of a ring, and 69a is a retaining projection made of a flange. These function in the same manner as the sealing screw 13 of the above embodiment. In addition, the configuration and operational effects other than those described above are all the same as those of the sealing screw 13 of the above embodiment. Further, the winding direction of the coil spring 63, the position of the protrusion 63a, and the material of each member are the same as those described for the sealing screw 13 of the above embodiment.

図１１，１２は、封印ネジの別の変更例を示したものであり、この封印ネジ５５は、金属製の雄ネジ部６１とこの雄ネジ部６１の軸線上に一体に設けた金属製の回転部材６２とを備えるとともに、この回転部材６２の先端すなわち雄ネジ部６１とは反対端にフランジからなる抜止め用突部６２ａを形成している。上記のようにした回転部材６２は、金属製の回転操作部材６４で覆うが、この回転操作部材６４は、円筒部６４ａとこの円筒部６４ａの一方の開口をふさぐ覆い部６４ｂとによって袋ナット状にしている。   FIGS. 11 and 12 show another modified example of the sealing screw. The sealing screw 55 is made of a metal male screw 61 and a metal screw integrally provided on the axis of the male screw 61. A rotation member 62 is provided, and a protrusion protrusion 62 a made of a flange is formed at the tip of the rotation member 62, that is, the end opposite to the male screw portion 61. The rotary member 62 configured as described above is covered with a metal rotary operation member 64. The rotary operation member 64 is formed in a cap nut shape by a cylindrical portion 64a and a cover portion 64b that closes one opening of the cylindrical portion 64a. I have to.

そして、回転部材６２の外周と上記回転操作部材６４の円筒部６４ａ内面との間に空間７０を形成するとともに、この空間７０に円柱状の回転体７１を組み入れている。そして、空間７０は、図１２に示すように、上記雄ネジ部６１を締め付ける回転方向（矢印方向）に向かって幅広部７０ａから徐々に幅狭部７０ｂに変化する構成にしている。そして、幅広部７０ａのうち最大の幅を保持した部分は、上記回転体７１の直径よりも大きくし、この部分に位置する回転体７１が自由回転できるようにしている。したがって、上記雄ネジ部６１を緩める方向に回転操作部材６４を回して、回転体７１が上記最大幅広部に位置したときには、回転操作部材６４と回転部材６２とが相対回転し、回転操作部材６４が回転部材６２に対して自由回転することになる。   A space 70 is formed between the outer periphery of the rotating member 62 and the inner surface of the cylindrical portion 64 a of the rotating operation member 64, and a columnar rotating body 71 is incorporated in the space 70. As shown in FIG. 12, the space 70 is configured to gradually change from the wide portion 70a to the narrow portion 70b in the rotation direction (arrow direction) in which the male screw portion 61 is tightened. The portion of the wide portion 70a that holds the maximum width is made larger than the diameter of the rotator 71 so that the rotator 71 located in this portion can freely rotate. Therefore, when the rotation operation member 64 is rotated in the direction of loosening the male screw portion 61 and the rotating body 71 is positioned at the maximum wide portion, the rotation operation member 64 and the rotation member 62 are relatively rotated, and the rotation operation member 64 is rotated. Will rotate freely with respect to the rotating member 62.

また、上記幅狭部７０ｂのうち、最小の幅を保持した部分は、上記回転体７１の直径よりも小さくし、この部分に回転体７１がはまり込んだとき、この回転体７１の自由回転が阻止されるとともに、この回転体７１を介して、回転操作部材６４の回転力が回転部材６２に伝達されるようにしている。したがって、上記雄ネジ部６１を締め付ける回転方向に回転操作部材６４を回して、回転体７１が上記最少幅狭部に位置したときには、回転操作部材６４と回転部材６２とが一体回転することになる。   In addition, the portion of the narrow portion 70b that holds the minimum width is made smaller than the diameter of the rotating body 71, and when the rotating body 71 is caught in this part, the rotating body 71 is free to rotate. While being blocked, the rotational force of the rotation operation member 64 is transmitted to the rotation member 62 through the rotating body 71. Therefore, when the rotation operation member 64 is rotated in the rotation direction for tightening the male screw portion 61 and the rotating body 71 is positioned at the minimum width narrow portion, the rotation operation member 64 and the rotation member 62 rotate integrally. .

さらに、上記幅狭部７０ｂの最も幅が狭い位置よりも、上記雄ネジ部６１の締め付け方向前方部位における回転操作部材６４の円筒部６４ａの内周に段部７２を形成し、この段部７２を境にして上記雄ネジ部６１の締め付け方向前方部位に、回転体７１の直径よりも大きな空間からなる拡幅部７３を形成している。   Further, a stepped portion 72 is formed on the inner periphery of the cylindrical portion 64a of the rotary operation member 64 at the front portion in the tightening direction of the male threaded portion 61 rather than the position where the narrowest portion 70b is the narrowest. A widened portion 73 having a space larger than the diameter of the rotating body 71 is formed at a front portion in the tightening direction of the male screw portion 61 with the above as a boundary.

したがって、雄ネジ部６１が回転操作部材６４の回転力で締め付けられて、それがネジ終端に達し、それ以上雄ネジ部６１が回転できなくなった状態で、回転操作部材６４をさらに回転させようとしたときには、回転体７１は段部７２を乗り越えて拡幅部７３に至る。したがって、回転体７１はこの拡幅部７３において自由回転ができることになる。拡幅部７３において回転体７１が自由回転できる状態では、回転操作部材６４をどのように強い力で回しても、それが空回転することになる。したがって、回転操作部材６４を強く回しても雄ネジ部６１がねじ切れたりしない。   Therefore, when the male screw portion 61 is tightened by the rotational force of the rotation operation member 64 and reaches the screw end, and the male screw portion 61 cannot be rotated any more, the rotation operation member 64 is further rotated. When doing so, the rotating body 71 gets over the stepped portion 72 and reaches the widened portion 73. Therefore, the rotating body 71 can freely rotate at the widened portion 73. In a state in which the rotating body 71 can freely rotate in the widened portion 73, no matter how strong the rotating operation member 64 is rotated, it rotates idly. Therefore, even if the rotation operation member 64 is rotated strongly, the male screw portion 61 is not broken.

なお、図中符号７４はリテーナー７５に保持されたスプリングで、上記回転体７１を幅狭部７０ｂの方向に押し付けるものである。また、符号７６は回転操作部材６４の覆い部６４ｂに形成した溝で、この溝７６に図示していないドライバーを差し込んで回転操作部材６４を回転させるものである。特に、この溝７６は、回転操作部材６４を締め付け対象の表面から理没させるような場合に有効に機能するものである。なお、この溝７６は、上記実施形態の封印ネジ１３、封印ネジ５１〜５４の覆い部６４ｂに形成すれば、同様の機能を発揮することは当然である。さらに、上記封印ネジ５５においては、回転体７１、空間７０の幅広部７０ａおよび幅狭部７０ｂが相まって、この発明の回転伝達機構を構成するものである。   In the figure, reference numeral 74 denotes a spring held by the retainer 75, which presses the rotating body 71 in the direction of the narrow portion 70b. Reference numeral 76 denotes a groove formed in the cover portion 64b of the rotation operation member 64, and a rotation driver 64 is inserted into the groove 76 to rotate the rotation operation member 64. In particular, the groove 76 functions effectively when the rotary operation member 64 is retracted from the surface to be tightened. In addition, if this groove | channel 76 is formed in the cover part 64b of the sealing screw 13 and the sealing screws 51-54 of the said embodiment, it is natural that the same function is exhibited. Further, in the sealing screw 55, the rotary body 71, the wide portion 70a and the narrow portion 70b of the space 70 are combined to constitute the rotation transmission mechanism of the present invention.

図１３は、封印ネジの別の変更例を示したものであり、この封印ネジ５６は、上記封印ネジ５５の段部７２および拡幅部７３を設けていないもので、その他は封印ネジ５５とまったく同じである。ちなみに、符号６２は回転部材、６４は回転操作部材、７０は空間、７０ａは幅広部、７０ｂは幅狭部、７１は円柱状の回転体、７４はスプリング、７５はリテーナーで、このほかに抜止め用突部およびドライバーを差し込む溝を備えていることは封印ネジ５５と同じである。   FIG. 13 shows another modified example of the sealing screw. This sealing screw 56 does not have the stepped portion 72 and the widened portion 73 of the sealing screw 55, and the rest is completely the same as the sealing screw 55. The same. Incidentally, reference numeral 62 is a rotating member, 64 is a rotating operation member, 70 is a space, 70a is a wide part, 70b is a narrow part, 71 is a cylindrical rotating body, 74 is a spring, 75 is a retainer. It is the same as the sealing screw 55 that it has a stop projection and a groove into which a screwdriver is inserted.

加えて、遊技機に搭載する制御装置は、上記実施形態の如く、上カバーと下カバーとを合着させて、それらのカバーの両端を封印ネジで螺着するものに限定されず、下カバーの上面において上カバーをスライドさせることによって上カバーと下カバーとを重ね合わせ、その状態で、封印ネジによって上カバーと下カバーとを一箇所あるいは複数箇所で螺着するもの等に変更することも可能である。   In addition, the control device mounted on the gaming machine is not limited to the one in which the upper cover and the lower cover are joined together and the both ends of these covers are screwed together with sealing screws as in the above embodiment. The upper cover and the lower cover can be overlapped by sliding the upper cover on the upper surface of the cover, and in that state, the upper cover and the lower cover can be screwed together at one place or a plurality of places with a sealing screw. Is possible.

たとえば、制御装置は、下カバーの矩形の底板の左右に側壁を上向きに垂設し、それらの側壁の上端際を内向きに折り返して、長尺帯状のスライドガイドを形成するとともに、上カバーの矩形の表面板の左右に側壁を下向きに垂設し、それらの側壁に、下カバーのスライドガイドと当接し合う長尺帯状の水平突起体を設け、かつ、下カバーの片方（あるいは両方）の側壁に沿ってネジ螺着体を設けるとともに、そのネジ螺着体と同側の上カバーの側壁に沿って、切断可能な取付片を介してネジ螺着部を設けたもの等に変更することが可能である。かかる制御装置は、下カバーの上に上カバーを載置し、下カバーのスライドガイドに上カバーの水平突起体を噛み合わせて、上カバーをスライドさせることによって、上カバーと下カバーとを重ね合わせ、その状態で、ネジ保持部内の封印ネジをネジ螺着部に螺着することによって、制御素子を搭載した基板を上カバーおよび下カバーによって覆った状態で保持することが可能である。   For example, the control device hangs the side walls upward on the left and right sides of the rectangular bottom plate of the lower cover, and folds the upper ends of the side walls inward to form a long belt-like slide guide. Side walls are hanged downward on the left and right sides of the rectangular surface plate, and a long band-shaped horizontal protrusion that comes into contact with the slide guide of the lower cover is provided on the side walls, and one (or both) of the lower cover is provided. A screw screwed body is provided along the side wall, and the screw screwed part is provided along the side wall of the upper cover on the same side as the screw screwed body through a cutable mounting piece. Is possible. Such a control apparatus places the upper cover on the lower cover, engages the horizontal protrusions of the upper cover with the slide guides of the lower cover, and slides the upper cover to overlap the upper cover and the lower cover. In addition, in this state, the sealing screw in the screw holding portion is screwed onto the screw screwing portion, whereby the substrate on which the control element is mounted can be held in a state covered with the upper cover and the lower cover.

制御装置を上記の如く構成した場合には、上カバーと下カバーとを単純に合着させる場合の如く２つのカバーを複数箇所において封印ネジで固着するものとする必要がなくなり、２つのカバーを一箇所のみにおいて封印ネジで固着することによって開放不能（痕跡を残すことなく開放不能）なものとすることが可能となる。   When the control device is configured as described above, it is not necessary to fix the two covers with sealing screws at a plurality of positions as in the case where the upper cover and the lower cover are simply joined together. It becomes impossible to open (cannot open without leaving a trace) by fixing with a sealing screw only at one place.

なお、上記実施形態においては遊技機がパチンコ機である場合の一例について説明したが、本発明の遊技機は、スロットマシーンやテレビゲーム等のパチンコ機以外の遊技機でも良い。   In the above embodiment, an example in which the gaming machine is a pachinko machine has been described. However, the gaming machine of the present invention may be a gaming machine other than a pachinko machine such as a slot machine or a video game.
