特開平11−000444号公報JP-A-11-000444

しかしながら、上記した上カバーに設けられたネジ保持部を封印ネジによって下カバーと螺着した制御装置は、ペンチ等の工具によって頭部を把持して封印ネジを緩める方向に回せば、当該封印ネジを外すことが可能となってしまうため、容易に上カバーを取り外すことができてしまう。このため、そのような制御装置を設けた遊技機においては、近年では、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できなくなっていた。   However, the control device in which the screw holding portion provided on the upper cover is screwed to the lower cover with a sealing screw can be used by grasping the head with a tool such as pliers and turning the sealing screw in the loosening direction. Since it becomes possible to remove, the upper cover can be easily removed. For this reason, in a gaming machine provided with such a control device, in recent years, it has been impossible to effectively prevent unauthorized replacement and unauthorized modification of control elements.

本発明の目的は、上記従来の遊技機の問題点を解消し、きわめて制度の高い封印機能を発揮する封印ネジによって制御装置の上下カバーが封印されており、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で実用的な遊技機を提供することにある。   The object of the present invention is to solve the above-mentioned problems of the conventional gaming machine, and the upper and lower covers of the control device are sealed with sealing screws that exhibit a very high sealing function. An object of the present invention is to provide a practical gaming machine that can be effectively prevented.

本発明は、遊技内容を制御するための制御装置を備えた遊技機であって、前記制御装置が、上カバー、およびその上カバーと合致する下カバーによって、制御素子を設置した基板が覆われているとともに、前記下カバーと螺合する封印ネジを保持したネジ保持部が、切断可能な取付片を介して前記上カバーの端縁に設けられており、そのネジ保持部に保持された前記封印ネジを前記下カバーと螺合することによって前記上カバーを前記下カバーに対して閉じた状態で保持するとともに、前記下カバーと螺合された前記ネジ保持部を前記上カバーから切断することによって、前記上カバーと前記下カバーとを分離するものであるとともに、前記封印ネジが、雄ネジ部にシャフトからなる回転部材を同一軸線上に設け、その回転部材の周囲に、その回転部材の外径よりもわずかに小さいコイル径を有するコイルスプリングを設け、このコイルスプリングを設けた回転部材を、袋ナット状の覆部を有する回転操作部材で覆うとともに、前記コイルスプリングの一端を前記回転操作部材の内面に止め、前記雄ネジ部を締め付ける方向に前記回転操作部材を回転させたとき前記コイルスプリングのコイル径を縮径して、前記コイルスプリングの内周を前記回転部材に圧接し、それらの前記回転部材と前記回転操作部材とを一体回転させる一方、前記回転操作部材を、前記雄ネジ部を緩める方向に回転させたとき、前記コイルスプリングの圧接力を小さくして、前記回転部材と前記回転操作部材とが相対回転するワンウェイクラッチ機構を備えており、前記雄ネジ部を締め付け対象にネジ結合させるとともに、前記回転操作部材を締め付け方向に回転させた場合に、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に、前記回転部材と前記回転操作部材とが、前記コイルスプリングの圧接力に抗して相対回転するものであることを特徴とするものである。上記予め定めた設定値は、当該封印ネジおよび締め付け対象の破壊強度などを基準に設定される。たとえば、回転操作部材を強引に回して、ネジ部を破壊したり、あるいは締め付け対象を破壊したりすれば、封印効果がなくなってしまう。したがって、上記設定値は、ネジをしっかり締め付けた後に、ネジ部や締め付け対象を破壊しない範囲で、回転操作部材が空転できる値ということになる。また、上記コイルスプリングのコイル径は、回転部材に対する圧入代が必要になるが、それはネジを締める方向に回転操作部材を回したとき、上記圧入代分の力を介して回転操作部材と回転部材とを一体化させなければならない。この締め代分を確保するコイル径が、当該回転部材の外径よりもわずかに小さいコイル径ということである。 The present invention is a gaming machine provided with a control device for controlling game content, wherein the control device covers a substrate on which a control element is installed by an upper cover and a lower cover that matches the upper cover. In addition, a screw holding portion that holds a sealing screw that is screwed to the lower cover is provided on an edge of the upper cover via a severable mounting piece, and the screw holding portion is held by the screw holding portion. The upper cover is held closed with respect to the lower cover by screwing a sealing screw with the lower cover, and the screw holding portion screwed with the lower cover is cut from the upper cover. The upper cover and the lower cover are separated from each other, and the sealing screw is provided with a rotating member made of a shaft on the male screw portion on the same axis, and around the rotating member. A coil spring having a coil diameter slightly smaller than the outer diameter of the rotating member is provided, the rotating member provided with the coil spring is covered with a rotating operation member having a cap nut-shaped cover, and one end of the coil spring is covered. stopped on the inner surface of the rotation operating member, the coil diameter of the coil spring and reduced in diameter when rotating the rotation operating member in a direction of tightening the male screw portion, the inner periphery of said coil spring to said rotary member While pressure-contacting and rotating the rotation member and the rotation operation member integrally, when rotating the rotation operation member in the direction of loosening the male screw portion, the pressure contact force of the coil spring is reduced, A one-way clutch mechanism in which the rotation member and the rotation operation member rotate relative to each other is provided, and the male screw portion is screw-coupled to a tightening target. In addition, when the rotation operation member is rotated in the tightening direction, when the tightening force of the screw connection reaches a predetermined set value, the rotation member and the rotation operation member are It is characterized in that it rotates relative to the pressing force. The predetermined set value is set based on the sealing screw and the breaking strength of the tightening target. For example, if the rotating operation member is forcibly turned to destroy the screw part or the target to be tightened, the sealing effect is lost. Therefore, the set value is a value that allows the rotation operation member to idle in a range in which the screw portion and the tightening target are not destroyed after the screw is firmly tightened. Moreover, the coil diameter of the coil spring requires a press-fitting allowance for the rotating member. When the rotating operation member is turned in the direction of tightening the screw, the rotating operation member and the rotating member are forced via the force for the press-fitting allowance. And must be integrated. The coil diameter that secures this tightening margin is a coil diameter slightly smaller than the outer diameter of the rotating member.

請求項1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、回転操作部材を締める方向に回したときには、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。この状態から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、上記回転操作部材に設けた覆部は、ネジ部と直結している回転部材の外周ほぼ全域を覆うので、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ができない。したがって、かかる封印ネジによれば、ネジ部を締める方向に回すときには、通常のネジと同様に締め付け力を発揮させることができる。また、ネジ部を緩める方向に回転操作部材を回そうとしても、それが空回りしてしまう。しかも、その回転部材は空回りする回転操作部材の覆部に覆われているので、回転部材を直接回すこともできない。結局、当該封印ネジは、それを締めることはできるが、緩めることができないということになり、ほぼ完璧な封印機能を発揮することができる。また、請求項1に記載された遊技機の制御装置に用いられる封印ネジによれば、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より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、不正改造を非常に効果的に防止することが可能となる。 When the sealing screw used in the control device of the gaming machine described in claim 1 is rotated in the direction in which the rotary operation member is tightened, the male screw portion rotates in the tightening direction to seal the object to be tightened. If the rotation operation member is turned in this direction to loosen the male screw portion, the rotation operation member rotates idle, so that the sealing screw cannot be loosened. In addition, since the cover provided on the rotation operation member covers almost the entire outer periphery of the rotation member directly connected to the male screw portion, the rotation member cannot be directly picked with pliers or the like and turned. Therefore, according to such a sealing screw, when turning the male screw portion in the tightening direction, the tightening force can be exerted in the same manner as a normal screw. Moreover, even if it is going to rotate a rotation operation member in the direction which loosens a male screw part, it will idle. Moreover, since the rotating member is covered with the cover of the rotating operation member that rotates idly, the rotating member cannot be directly rotated. Eventually, the sealing screw can be tightened but cannot be loosened, and can exhibit a nearly perfect sealing function. Moreover, according to the sealing screw used for the control device of the gaming machine according to claim 1, when the tightening force of the screw connection reaches a predetermined set value, the rotating member and the rotating operation member are Since it rotates relative to the pressure of the spring, the sealing screw cannot be tightened more than necessary and the threaded portion cannot be threaded. As described above, since the male 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 1, it is possible to very effectively prevent unauthorized replacement and unauthorized modification of the control element mounted inside the control device.

また、請求項1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、回転部材の周囲に設けられたコイルスプリングの一端が回転操作部材の内面に止められているため、より一層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一層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、不正改造をきわめて効果的に防止することが可能となる。 In addition, the sealing screw used in the control device for a gaming machine according to claim 1 is more perfect because one end of a coil spring provided around the rotating member is fixed to the inner surface of the rotating operation member. The sealing function can be demonstrated. 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 1 , 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、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 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 to secure a press-fitting allowance for the coil spring 63. Yes. 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の覆部64aで覆うが、この回転操作部材64は袋ナット状にして、回転操作部材64そのものが覆部64aとなる構成にしている。このようにした覆部64aの内壁面には軸線に平行にした掛け止溝64bを形成するとともに、この掛け止溝64bの下端を覆部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64b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 the cover portion 64a of the metal rotary operation member 64. The rotary operation member 64 is formed into a cap nut shape, and the rotary operation member 64 itself is covered. The configuration is 64a. A latching groove 64b parallel to the axis is formed on the inner wall surface of the cover part 64a thus configured, and the lower end of the latching groove 64b is opened to the lower end opening edge of the cover part 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 64b. 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部材65でふさぐ。このリング部材65は、その外周を覆部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。なお、このリング部材65は、回転操作部材64を回転部材62から引き抜く方向の大きな力が作用したとしてもそれが抜けないようにするためのものである。したがって、上記のように力が作用したとしても、リング部材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、圧入で十分であるが、その強度を維持できないときには、たとえば、リング部材65と回転操作部材64とを溶接したり、あるいはリング部材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 with the ring member 65. The outer periphery of the ring member 65 is press-fitted and fixed inside the cover portion 64a, and the rotation member 62 is relatively rotatable. The ring member 65 is provided so that it does not come out even when a large force in the direction of pulling out the rotation operation member 64 from the rotation member 62 is applied. Therefore, even if a force is applied as described above, press-fit is sufficient if sufficient strength can be secured to prevent the ring member 65 from coming off the rotation operation member 64, but when the strength cannot be maintained, For example, the ring member 65 and the rotation operation member 64 may be welded, or the ring member 65 and the rotation operation member 64 may be fitted with screws.

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。
=(EIδ/R )X(e2πμN−1) ・・・・・・・ (1)
=(EIδ/R )X{1−(1/e2πμN)} ・・・・ (2)
上記(1)式のTはロックトルクであり、(2)式のT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
・・・・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 = (EI δ / R A 2 ) X (e 2πμN −1) (1)
T S = (EIδ / R A 2 ) X {1- (1 / e 2πμN )} (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T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T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の覆部64aで、回転部材62の外周ほぼ全域が覆われていなければならない。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。   When the rotation operation member 64 is rotated and the male screw portion 61 is completely tightened as described above, the entire outer periphery of the rotation member 62 must be covered with the cover portion 64a 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, 9 other than the uppermost screw engaging body 20 on the left side and the lowermost screw holding portion 9 (i.e., 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 traces always remain when 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、回転操作部材64を締める方向に回したときには、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。この状態から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、回転操作部材64に設けた覆部64bは、ネジ部と直結している回転部材62の外周ほぼ全域を覆うので、回転部材62をペンチなどで直接摘んでそれを回すことができない。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、かかる封印ネジ13によれば、ネジ部を締める方向に回すときには、通常のネジと同様に締め付け力を発揮させることができる。また、ネジ部を緩める方向に回転操作部材64を回そうとしても、それが空回りしてしまう。しかも、その回転部材62は空回りする回転操作部材64の覆部64bに覆われているので、回転部材62を直接回すこともできない。したがって、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、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制御素子(ROM8)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。
[Effect of pachinko machine]
When the sealing screw 13 used in the control device 1 of the pachinko machine 81 is rotated in the direction in which the rotation operation member 64 is tightened, the screw portion rotates in the tightening direction to seal the object to be tightened. If the rotation operation member 64 is rotated in the direction of loosening the screw portion from this state, the rotation operation member 64 rotates idle, and thus the sealing screw 13 cannot be loosened. In addition, the cover portion 64b provided on the rotation operation member 64 covers almost the entire outer periphery of the rotation member 62 that is directly connected to the screw portion. Therefore, the rotation 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, according to the sealing screw 13, when the screw portion is turned in the tightening direction, the tightening force can be exerted in the same manner as a normal screw. Moreover, even if it tries to rotate the rotation operation member 64 in the direction which loosens a screw part, it will rotate idly. Moreover, since the rotating member 62 is covered with the cover portion 64b of the rotating operation member 64 that rotates idly, the rotating member 62 cannot be directly rotated. 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 and 10. Therefore, according to the pachinko machine 81, it is possible to effectively prevent unauthorized replacement and unauthorized modification of the control element (ROM 8) mounted inside the control device 1.

また、封印ネジ13によれば、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62と回転操作部材64とが、コイルスプリング63の圧接力に抗して相対回転するので、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。したがって、封印ネジ13は、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することができる。それゆえ、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制御素子(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可能となる。   Further, according to the sealing screw 13, when the tightening force of the screw connection reaches a predetermined set value, the rotating member 62 and the rotating operation member 64 rotate relative to 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. Accordingly, since the sealing screw 13 cannot be loosened or threaded, the sealing 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 and 10. Therefore, according to the pachinko machine 81, it is possible to very effectively prevent unauthorized replacement and unauthorized modification of the control element (ROM 8) mounted inside the control device 1.

さらに、封印ネジ13は、回転部材62の周囲に設けられたコイルスプリング63の一端が回転操作部材64の内面に止められているため、より一層完璧な封印機能を発揮することができる。それゆえ、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制御素子(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可能となる。   Furthermore, since the seal screw 13 has one end of a coil spring 63 provided around the rotation member 62 being stopped by the inner surface of the rotation operation member 64, a more 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 and 10. Therefore, according to the pachinko machine 81, it is possible to extremely effectively prevent unauthorized replacement and unauthorized modification of the control element (ROM 8) mounted inside the control device 1.

[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71は、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71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フランジ部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 modification example of the sealing screw. When the sealing screw 71 is inserted into the rotation operation member 64 with a certain press-fitting margin, the rotation operation member 64 is rotated. The coil spring 63 has a larger diameter, and will be described in more detail below. A retaining groove 62 b parallel to the axis is formed outside the rotating member 62 of the sealing screw 71, 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. 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 inner diameter direction is provided.

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2中、符号61は雄ネジ部、62aはフランジ部、64aは覆部、65はリング部材であって、それらは第1実施形態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. 2, reference numeral 61 denotes a male screw portion, 62a denotes a flange portion, 64a denotes a cover portion, and 65 denotes a ring member, which function in the same manner as in the first embodiment.

上記のようにした封印ネジ71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 the sealing screw 71 configured as described above is used, the rotation operation member 64 is rotated in the direction in which the male screw portion 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.
