Description

本発明は、遊技機の基板ケースなどに適用されるセキュリティ構造に関し、特に、連結ピンを用いて分離不能に連結された二つの部材に対する連結解除の痕跡を識別可能に残すセキュリティ構造に関する。 The present invention relates to a security structure applied to a board case or the like of a gaming machine, and more particularly to a security structure that leaves a trace of disconnection of two members that are connected inseparably using a connection pin.

一般に、スロットマシン、パチンコなどの遊技機では、遊技機の動作を制御するＩＣ、ＲＯＭなどの電子部品を実装した制御基板が備えられている。
近年、この種の遊技機の制御基板は、不正行為者によるＲＯＭなどの交換や改造、不正部品の追加、接続など、悪質な不正行為の標的となっており、その被害は深刻なものとなっている。 Generally, a gaming machine such as a slot machine or a pachinko machine is provided with a control board on which electronic components such as an IC and a ROM for controlling the operation of the gaming machine are mounted.
In recent years, the control board of this type of gaming machine has been a target of malicious fraud such as replacement and modification of ROMs, addition of illegal parts, and connection by fraudsters, and the damage becomes serious. ing.

このような遊技機の制御基板に対する不正行為を排除する手段として、従来から、制御基板全体を所定の基板ケース内に収納し、この基板ケースを開放不能に封印固定した状態で遊技機側に取り付けるという対策が講じられてきた。
そして、遊技機の制御基板を収納した基板ケースを開放不能に封印固定する方法としては、連結ピンを用いて二つの部材を分離不能に連結する連結構造が広く用いられていた。 Conventionally, as a means for eliminating fraudulent acts on the control board of such a gaming machine, the entire control board is housed in a predetermined board case, and the board case is attached to the gaming machine side in a state where it is sealed and fixed so that it cannot be opened. Measures have been taken.
And as a method of sealing and fixing the case that houses the control board of the gaming machine so that it cannot be opened, a connecting structure that connects the two members so as to be unseparable using a connecting pin has been widely used.

ところが、悪質な場合は、ニッパなどの剪断工具を用意し、その連結ピンを切断して、ケースを開封する不正行為者がいた。
そこで、連結ピンの切断によるケースの開封を困難にする技術が提案されている。
例えば、ケースカバーとケース本体を開封するために破断するとその痕跡が残る破断部と、ケース側部の突出部材に施された電気配線を遮断すると制御基板に痕跡が残る制御基板切断部位とを備えたものがある（例えば、特許文献１参照。）。
これによれば、破断部と制御基板切断部位の二箇所を切断しなければケースカバーを開封できないので、開封が困難となり、不正行為の意欲を減衰させることができる。 However, in the case of viciousness, there was a fraudster who prepared a shearing tool such as a nipper, cut the connecting pin, and opened the case.
Therefore, a technique for making it difficult to open the case by cutting the connecting pin has been proposed.
For example, the case cover and the case main body are provided with a broken portion that leaves a trace when the case body is broken and a control board cutting portion that leaves a trace on the control board when the electrical wiring applied to the protruding member on the case side is cut off. (For example, refer to Patent Document 1).
According to this, since the case cover cannot be opened unless two parts of the breakage part and the control board cutting part are cut, it is difficult to open the case cover, and the willingness of fraud can be attenuated.

また、連結ピンに関する技術としては、次のものがある。
例えば、外光を受けて発電する太陽電池と、この太陽電池からの電力の供給を受けて発光するＬＥＤと、これら太陽電池とＬＥＤとを接続する配線とを連結ピンに備え、ケースカバーとケース本体との封止状態を解除するために連結ピンの突起部を切断すると、この突起部に埋め込まれた配線も切断され、ＬＥＤが消灯するものがある（例えば、特許文献２参照。）。
これによれば、ＬＥＤが消灯していることを確認することで、ケースカバーとケース本体との封止状態が解除されたことを容易に発見できる。 Moreover, there exist the following as a technique regarding a connection pin.
For example, the connecting pin includes a solar cell that generates power by receiving external light, an LED that emits light by receiving power supplied from the solar cell, and a wiring that connects the solar cell and the LED. When the protruding portion of the connecting pin is cut to release the sealing state with the main body, the wiring embedded in the protruding portion is also cut to turn off the LED (for example, see Patent Document 2).
According to this, it can be easily found that the sealing state between the case cover and the case main body is released by confirming that the LED is turned off.

しかしながら、特許文献１に記載の技術は、ケースカバーを開封する際に、制御基板の一部を切断するので、この切断によって基板本体の回路や機器に悪影響を及ぼしていた。
また、同技術においては、各制御基板切断部位の電気配線に抵抗を設けて、切断時の抵抗による電圧変化で開封履歴を保持していた。このため、ＣＰＵ、記憶装置に負担がかかり、遊技機本来の演出制御を行う主制御基板に影響を及ぼしていた。
さらに、特許文献２に記載の技術は、太陽電池という高価な部品を搭載する必要があるので、コスト高となっていた。 However, since the technique described in Patent Document 1 cuts a part of the control board when opening the case cover, the cutting has had an adverse effect on the circuit and equipment of the board body.
Further, in this technology, a resistance is provided in the electric wiring of each control board cutting site, and the opening history is held by a voltage change due to the resistance at the time of cutting. For this reason, a load is imposed on the CPU and the storage device, which affects the main control board that performs the original effect control of the gaming machine.
Furthermore, since the technique described in Patent Document 2 needs to mount an expensive component called a solar cell, the cost is high.

しかも、特許文献１及び２に記載の技術は、ケースカバーとケース本体との封止状態が解除されたかどうかについては判断できるものの、連結ピンの係合によりケースカバーとケース本体が本当に分離不能な封止状態となったかどうかを判断することはできなかった。 Moreover, although the techniques described in Patent Documents 1 and 2 can determine whether or not the sealed state of the case cover and the case body has been released, the case cover and the case body cannot be really separated by the engagement of the connecting pins. It was not possible to determine whether the sealed state was reached.

本発明は、上記の事情にかんがみなされたものであり、制御基板や制御回路に負担をかけることなく、制御基板ケースの破断の痕跡を残すとともに、ケースカバーとケース本体が本当に封止状態となったかどうかを判断可能とするセキュリティ構造の提供を目的とする。 The present invention has been considered in view of the above circumstances, leaving a trace of the breakage of the control board case without imposing a burden on the control board and the control circuit, and the case cover and the case main body are truly sealed. The purpose is to provide a security structure that can determine whether or not

この目的を達成するため、本発明のセキュリティ構造は、分離不能に連結された二つの部材に対する連結解除の痕跡を識別可能に残すセキュリティ構造であって、一方の部材側から行われる押し込み操作に応じて、一方の部材及び他方の部材に形成された孔部を貫通するとともに、他方の部材に係合することによって二つの部材を連結する連結ピンと、電力を受けて所定の動作を行う報知部と、この報知部に電力を送る給電部と、を備え、連結ピンが、給電部から供給される電流の経路の一部を構成可能な導電部を有し、連結ピンによる二つの部材の連結前と連結後で報知部の動作態様が異なり、二つの部材に対する連結解除の前後で報知部の動作態様が異なる構成としてある。 In order to achieve this object, the security structure of the present invention is a security structure in which a trace of release of connection between two members that are connected inseparably is identifiable, and is in response to a push-in operation performed from one member side. A connecting pin that passes through the hole formed in one member and the other member and connects the two members by engaging with the other member, and a notifying unit that receives electric power and performs a predetermined operation A power feeding unit that sends power to the notification unit, and the connection pin has a conductive part that can form part of a path of a current supplied from the power supply unit, and before the two members are connected by the connection pin The operation mode of the notification unit is different after connection, and the operation mode of the notification unit is different before and after the connection between the two members is released.

本発明のセキュリティ構造によれば、連結ピンを用いて二つの部材を分離不能に連結する連結構造において、制御基板を破断することなく二つの部材の連結が解除されるので、制御基板に負担をかけることがない。
また、制御回路を構成するＣＰＵや記憶装置を用いずに、封止状態の解除を検出するので、制御回路に負担をかけることがない。
さらに、連結ピンによる二つの部材の連結前と連結後で報知部の動作態様が異なるので、ケースカバーとケース本体が本当に分離不能な封止状態となったかどうかを判断できる。 According to the security structure of the present invention, in the connection structure in which the two members are connected to each other using the connection pins, the connection between the two members is released without breaking the control board. I don't spend it.
Further, since the release of the sealed state is detected without using the CPU and the storage device that constitute the control circuit, there is no burden on the control circuit.
Further, since the operation mode of the notification unit is different before and after the connection of the two members by the connection pin, it can be determined whether or not the case cover and the case main body are in a sealed state that cannot be separated.

以下、本発明の実施形態について、図面を参照して説明する。

これらの図に示すように、本発明の実施形態に係るセキュリティ構造が適用される制御基板ケース１０は、互に開閉可能に嵌合する上ケース２０及び下ケース３０を備えて構成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of a control board case to which a security structure according to an embodiment of the present invention is applied. FIG. 2 is a sealed state in which the security structure according to the embodiment of the present invention is applied and cannot be separated. It is the external appearance perspective view of a control board case.
As shown in these drawings, the control board case 10 to which the security structure according to the embodiment of the present invention is applied includes an upper case 20 and a lower case 30 that are fitted to each other so as to be openable and closable.

上ケース２０及び下ケース３０は、互に開閉可能に嵌合して遊技機用制御基板（図示せず）の収納ケースを構成するようになっており、全体が透明プラスチックからなる筐体構造となっている。
上ケース２０には、下ケース３０のヒンジ部（図示せず）と回動自在に係合するヒンジ部（図示せず）が設けられ、これらヒンジ部によって、上ケース２０と下ケース３０が開閉自在に組み立てられるようになっている。 The upper case 20 and the lower case 30 are fitted to each other so as to be openable and closable to form a storage case for a control board for a gaming machine (not shown). It has become.
The upper case 20 is provided with a hinge portion (not shown) that rotatably engages with a hinge portion (not shown) of the lower case 30, and the upper case 20 and the lower case 30 are opened and closed by these hinge portions. It can be assembled freely.

また、上ケース２０及び下ケース３０の開閉側（ヒンジ部と反対側の端部）には、互に上下に重合するように複数の封印固定部２１、３１（Ａ、Ｆ）が突出形成され、これらの封印固定部２１、３１同士が、連結ピン４０ａを介して分離不能に連結されるようになっている。 In addition, a plurality of sealing fixing portions 21 and 31 (A, F) are formed to protrude on the open / close side (end portion opposite to the hinge portion) of the upper case 20 and the lower case 30 so as to overlap each other. These sealing fixing portions 21 and 31 are connected to each other in a non-separable manner via a connecting pin 40a.

さらに、上ケース２０には、ケース側面側にも、複数の封印固定部２１（Ｂ〜Ｅ）が形成されている。
このケース側面側の封印固定部２１は、制御基板ケース１０が図示しない遊技機側に取り付けられた場合に、遊技機側に備えられる封印固定部（図示せず）と対応する位置に形成されており、これらの封印固定部同士を連結ピン４０ａを用いて連結させることで、制御基板ケース１０と遊技機とを分離不能に連結固定することができる。 Furthermore, the upper case 20 is also formed with a plurality of sealing fixing portions 21 (B to E) on the side surface of the case.
The case fixing portion 21 on the side of the case is formed at a position corresponding to a sealing fixing portion (not shown) provided on the gaming machine side when the control board case 10 is attached to the gaming machine side (not shown). In addition, the control board case 10 and the gaming machine can be connected and fixed so as not to be separated by connecting these seal fixing parts using the connection pins 40a.

次に、本実施形態に係る制御基板ケース１０の連結構造について、図３〜図５を参照して説明する。
図３の（ａ）は、連結ピンの構造を示す外観正面図、図３の（ｂ）は、連結ピンに嵌め込まれる導電部の構造を示す拡大斜視図、図４は、連結ピンが押し込み挿入される前の状態を示す封印固定部の縦方向断面図（図２のＩ−Ｉ断面図）、図５は、連結ピンが押し込み挿入された状態を示す封印固定部の縦方向断面図（図２のＩ−Ｉ断面図）である。 Next, the connection structure of the control board case 10 according to the present embodiment will be described with reference to FIGS.

本実施形態に係る制御基板ケース１０の連結構造では、上ケース２０及び下ケース３０に形成される封印固定部２１、３１同士が連結ピン４０ａを用いて分離不能に連結されるとともに、開封時に開封部２２の切断を要求し、この切断跡が開封の痕跡として残るように構成されている。
なお、ここでは、封印固定部２１、３１の連結構造について先に説明し、開封部２２の構造をその後に説明する。 In the connection structure of the control board case 10 according to the present embodiment, the seal fixing portions 21 and 31 formed on the upper case 20 and the lower case 30 are connected to each other using the connection pins 40a so as not to be separated and opened at the time of opening. The cutting of the part 22 is requested, and this cutting trace is configured to remain as an opening trace.
Here, the connection structure of the seal fixing parts 21 and 31 will be described first, and the structure of the opening part 22 will be described later.

封印固定部２１、３１同士は、連結ピン４０ａを用いて分離不能に連結される。連結ピン４０ａは、図３に示すように、押し込み操作される頭部４１と、この頭部４１に一体的に連続する軸部４２と、この軸部４２の先端外周部に一体的に形成される係合爪部４３とを有する樹脂製のもので、係合爪部４３は、先端側ほど細くなるテーパー形状になっている。
また、軸部４２（係合爪部４３）には、先端部から基端部にわたって切り込み状の溝部４４が形成されている。そのため、側方から押圧力を受けたとき、弾性変形によって係合爪部４３の径が縮小するようになっている。 The seal fixing portions 21 and 31 are connected to each other in a non-separable manner using a connecting pin 40a. As shown in FIG. 3, the connecting pin 40 a is integrally formed on a head portion 41 that is pushed in, a shaft portion 42 that is integrally continuous with the head portion 41, and a tip outer peripheral portion of the shaft portion 42. The engaging claw portion 43 has a tapered shape that becomes thinner toward the distal end side.
Further, the shaft portion 42 (engagement claw portion 43) is formed with a notched groove portion 44 extending from the distal end portion to the proximal end portion. Therefore, when a pressing force is received from the side, the diameter of the engaging claw portion 43 is reduced by elastic deformation.

さらに、連結ピン４０ａには、銅や鉄などの導電性材料で形成され、後述する検出回路５０に流れる電流を制御する導電部４５ａが外方から嵌め込まれている。導電部４５ａは、図３（ｂ）に示すように、導電性材料を用いて環状に形成した上部接点部４５ａ−１と、同じく導電性材料を用いて環状に形成した下部接点部４５ａ−２と、これらを上下に配置して環状内側同士を導電性材料で連接した連接部４５ａ−３とを有した構造となっている。 Furthermore, a conductive portion 45a that is formed of a conductive material such as copper or iron and that controls a current flowing in a detection circuit 50 described later is fitted into the connection pin 40a from the outside. As shown in FIG. 3B, the conductive portion 45a includes an upper contact portion 45a-1 formed in a ring shape using a conductive material and a lower contact portion 45a-2 formed in a ring shape using the same conductive material. And it has the structure which has these and the connection part 45a-3 which has arrange | positioned up and down and connected annular inner side with the electroconductive material.

上部接点部４５ａ−１と下部接点部４５ａ−２のそれぞれの環状内側の径は、いずれも連結ピン４０ａの軸部４２の径とほぼ同じか僅かに大きくなっている。また、上部接点部４５ａ−１と下部接点部４５ａ−２は、一箇所に切込部４５ａ−４が形成されてＣ字形状となっており、この切込部４５ａ−４により分かれたＣ字形状の二つの端部の一方又は双方を上方又は下方へ弾性的に曲げることで、この導電部４５ａを連結ピン４０ａの外方から嵌合できるようになっている。 The diameters of the annular inner sides of the upper contact part 45a-1 and the lower contact part 45a-2 are both substantially the same as or slightly larger than the diameter of the shaft part 42 of the connecting pin 40a. Further, the upper contact portion 45a-1 and the lower contact portion 45a-2 are formed in a C shape with a cut portion 45a-4 formed at one place, and the C shape separated by the cut portion 45a-4. By electrically bending one or both of the two end portions of the shape upward or downward, the conductive portion 45a can be fitted from the outside of the connecting pin 40a.

この導電部４５ａの連接部４５ａ−３の長さは、連結ピン４０ａの軸部４２の長さとほぼ同じになっている。このため、導電部４５ａを連結ピン４０ａに嵌合した場合、上部接点部４５ａ−１は、連結ピン４０ａの頭部４１の底面４１−１に並接し、下部接点部４５ａ−２は、係合爪部４３の上面４３−１に並接し、連接部４５ａ−３は、軸部４２の側面に並接される。
なお、頭部４１の底面４１−１と上部接点部４５ａ−１、係合爪部４３の上面４３−１と下部接点部４５ａ−２、軸部４２と連接部４５ａ−３は、それぞれ接着剤などで固着してもよい。
また、連結ピン４０ａの軸部４２の表面に軸方向の溝部（図示せず）を形成し、ここに導電部４５ａの連接部４５ａ−３を嵌め込むようにしてもよい。 The length of the connecting portion 45a-3 of the conductive portion 45a is substantially the same as the length of the shaft portion 42 of the connecting pin 40a. Therefore, when the conductive portion 45a is fitted to the connecting pin 40a, the upper contact portion 45a-1 is in parallel with the bottom surface 41-1 of the head 41 of the connecting pin 40a, and the lower contact portion 45a-2 is engaged. The joint part 45 a-3 is juxtaposed to the side surface of the shaft part 42 in parallel with the upper surface 43-1 of the claw part 43.
The bottom surface 41-1 and the upper contact portion 45a-1 of the head 41, the upper surface 43-1 and the lower contact portion 45a-2 of the engaging claw portion 43, and the shaft portion 42 and the connecting portion 45a-3 are respectively adhesives. It may be fixed by, for example.
Alternatively, an axial groove (not shown) may be formed on the surface of the shaft portion 42 of the connecting pin 40a, and the connecting portion 45a-3 of the conductive portion 45a may be fitted therein.

上ケース２０の封印固定部２１は、上下方向を向く円筒形状に形成され、その内側に、連結ピン４０ａの頭部４１よりも僅かに径寸法が大きい丸孔２１−１を有している。丸孔２１−１の下側には、壁部２１−２を有しており、ここに挿通孔２１−３が形成されている。
挿通孔２１−３の径寸法は、連結ピン４０ａの頭部４１よりも小さく、軸部４２よりも僅かに大きく、また、係合爪部４３よりも僅かに小さく設定されている。 The sealing fixing portion 21 of the upper case 20 is formed in a cylindrical shape facing in the vertical direction, and has a round hole 21-1 having a slightly larger diameter than the head 41 of the connecting pin 40a. A wall 21-2 is provided below the round hole 21-1, and an insertion hole 21-3 is formed therein.
The diameter of the insertion hole 21-3 is set to be smaller than the head 41 of the connecting pin 40a, slightly larger than the shaft portion 42, and slightly smaller than the engaging claw portion 43.

また、壁部２１−２には、導電性材料で形成された環状の上部接触子（第一接触子）２１−４がその壁部２１−２の上面２１−５に沿って配置されている。この上部接触子２１−４の外周の一部には、突起部２１−４１が形成されており、壁部２１−２の上面２１−５から封印固定部２１の外周面に向かって穿設された貫通孔２１−６に挿入され、外周面から突出して、その先端が開封部２２付近に達し、上部配線２２−１を介して検出回路５０に接続されている。 In addition, an annular upper contact (first contact) 21-4 made of a conductive material is disposed on the wall 21-2 along the upper surface 21-5 of the wall 21-2. . A protruding portion 21-41 is formed on a part of the outer periphery of the upper contact 21-4, and is drilled from the upper surface 21-5 of the wall portion 21-2 toward the outer peripheral surface of the seal fixing portion 21. It is inserted into the through-hole 21-6, protrudes from the outer peripheral surface, its tip reaches the vicinity of the opening portion 22, and is connected to the detection circuit 50 via the upper wiring 22-1.

下ケース３０の封印固定部３１も、上下方向を向く円筒形状に形成され、その内側に丸孔３１−１を有している。丸孔３１−１の上側には、壁部３１−２を有しており、ここに係止孔３１−３が形成されている。
係止孔３１−３の径寸法は、連結ピン４０ａの軸部４２よりも僅かに大きく、また、係合爪部４３よりも僅かに小さく設定されている。 The sealing fixing portion 31 of the lower case 30 is also formed in a cylindrical shape facing the up and down direction, and has a round hole 31-1 inside thereof. A wall portion 31-2 is provided on the upper side of the round hole 31-1, and a locking hole 31-3 is formed therein.
The diameter of the locking hole 31-3 is set slightly larger than the shaft portion 42 of the connecting pin 40 a and slightly smaller than the engaging claw portion 43.

また、壁部３１−２には、導電性材料で形成された環状の下部接触子（第二接触子）３１−４がその壁部３１−２の下面３１−５に沿って配置されている。この下部接触子３１−４の外周の一部には、突起部３１−４１が形成されており、壁部３１−２の下面３１−５から封印固定部３１の外周面に向かって穿設された貫通孔３１−６に挿入され、その先端が下ケース３０の本体に向かって外周面から突出し、下部配線３２を介して検出回路５０に接続されている。 In addition, an annular lower contact (second contact) 31-4 formed of a conductive material is disposed on the wall 31-2 along the lower surface 31-5 of the wall 31-2. . A protrusion 31-41 is formed on a part of the outer periphery of the lower contact 31-4, and is drilled from the lower surface 31-5 of the wall 31-2 toward the outer peripheral surface of the sealing fixing portion 31. The distal end of the through hole 31-6 protrudes from the outer peripheral surface toward the main body of the lower case 30 and is connected to the detection circuit 50 via the lower wiring 32.

そして、上ケース２０及び下ケース３０の封印固定部２１、３１が重合した状態で、上ケース２０の封印固定部２１（丸孔２１−１）に連結ピン４０ａを押し込むと、先端部のテーパーガイドにより係合爪部４３が縮径状態で挿通孔２１−３を通過する。この通過後、係合爪部４３は、一旦弾性復元して封印固定部２１の壁部２１−２の底面に係合する（図４参照）。
この係合により、連結ピン４０ａが上ケース２０の封印固定部２１から抜けるのを防止できる。 Then, when the connecting pin 40a is pushed into the sealing and fixing part 21 (round hole 21-1) of the upper case 20 in a state where the sealing and fixing parts 21 and 31 of the upper case 20 and the lower case 30 are overlapped, a taper guide at the tip part. Thus, the engaging claw portion 43 passes through the insertion hole 21-3 in a reduced diameter state. After this passage, the engaging claw portion 43 is once elastically restored and engaged with the bottom surface of the wall portion 21-2 of the seal fixing portion 21 (see FIG. 4).
By this engagement, it is possible to prevent the connecting pin 40a from coming off from the sealing fixing portion 21 of the upper case 20.

また、上ケース２０及び下ケース３０の封印固定部２１、３１が重合した状態で、さらに連結ピン４０ａを下ケース３０の封印固定部３１（丸孔３１−１）に押し込むと、先端部のテーパーガイドにより係合爪部４３が縮径状態で係止孔３１−３を通過する。このとき、頭部４１は、挿通孔２１−３の通過が規制され、また、係合爪部４３は、係止孔３１−３を通過後、弾性復元して封印固定部３１の壁部３１−２の下面３１−５に係合する（図５参照）。
これにより、上ケース２０及び下ケース３０の封印固定部２１、３１が連結ピン４０ａを介して一体的に連結固定される。 Further, when the connecting pin 40a is further pushed into the sealing and fixing portion 31 (round hole 31-1) of the lower case 30 in a state where the sealing and fixing portions 21 and 31 of the upper case 20 and the lower case 30 are overlapped, the taper at the tip end portion is tapered. With the guide, the engaging claw portion 43 passes through the locking hole 31-3 in a reduced diameter state. At this time, the head 41 is restricted from passing through the insertion hole 21-3, and the engaging claw 43 is elastically restored after passing through the locking hole 31-3, and the wall portion 31 of the seal fixing portion 31. -2 is engaged with the lower surface 31-5 (see FIG. 5).
As a result, the sealing fixing portions 21 and 31 of the upper case 20 and the lower case 30 are integrally connected and fixed via the connecting pin 40a.

そして、これら封印固定部２１、３１が連結固定された状態においては、連結ピン４０ａの導電部４５ａの上部接点部４５ａ−１が封印固定部２１の上部接触子２１−４に接合し、導電部４５ａの下部接点部４５ａ−２が封印固定部３１の下部接触子３１−４に接合する。ここで、上部接点部４５ａ−１と下部接点部４５ａ−２は、連接部４５ａ−３を介して連接しており、これらは導電性材料で形成されているため、上部接触子２１−４と下部接触子３１−４が導電部４５ａを介して電気的に導通可能となる。 And in the state where these sealing fixing parts 21 and 31 are connected and fixed, the upper contact part 45a-1 of the conductive part 45a of the connecting pin 40a is joined to the upper contactor 21-4 of the sealing fixing part 21, and the conductive part The lower contact portion 45a-2 of 45a is joined to the lower contact 31-4 of the seal fixing portion 31. Here, the upper contact portion 45a-1 and the lower contact portion 45a-2 are connected via a connecting portion 45a-3, and these are formed of a conductive material. The lower contact 31-4 can be electrically connected via the conductive portion 45a.

このように連結ピン４０ａが押し込み挿入される封印固定部２１は、上ケース２０との間が開封部２２によって結合されている。開封部２２は、意識的に切断容易な板状に形成されており、ニッパなどの剪断工具を用いて切断することにより、封印固定部２１が上ケース２０から分離され、制御基板ケース１０の開閉が可能になっている。開封部２２の切断跡は、開封の痕跡として残り、これを確認することで開封の有無が判定される。 Thus, the sealing fixing part 21 into which the connecting pin 40a is pushed and inserted is joined to the upper case 20 by the opening part 22. The opening part 22 is formed in a plate shape that is consciously easy to cut, and the sealing fixing part 21 is separated from the upper case 20 by cutting with a shearing tool such as a nipper, and the control board case 10 is opened and closed. Is possible. The cutting trace of the opening part 22 remains as an opening trace, and the presence or absence of opening is determined by confirming this.

なお、本実施形態では、封印固定部２１が、二つの開封部２２を介して上ケース２０に結合されている。
これにより、上ケース２０の開封に際し、一つの封印固定部２１につき、二つの開封部２２を切断することが要求され、痕跡を残さない開封や、痕跡の隠蔽が更に困難になる。 In the present embodiment, the seal fixing part 21 is coupled to the upper case 20 via the two opening parts 22.
As a result, when opening the upper case 20, it is required to cut the two opening portions 22 for one sealing fixing portion 21, and it becomes more difficult to open and leave no traces.

また、開封部２２には、極細裸リード線などで形成された上部配線２２−１が配設されており、図６に示すように、開封部２２が切断されると、上部配線２２−１も一緒に切断されるようになっている。上部配線２２−１が切断されると、後述する検出回路５０ａに流れる電流の経路も変わるため、報知部の動作を切替制御することができる。この上部配線２２−１の切断による報知部の動作の切替制御については、後記の「検出回路及びその動作」にて詳述する。 Further, an upper wiring 22-1 formed of an ultrafine bare lead wire or the like is disposed in the unsealed portion 22, and when the unsealed portion 22 is cut as shown in FIG. Are designed to be cut together. When the upper wiring 22-1 is disconnected, the path of a current flowing in a detection circuit 50a described later is also changed, so that the operation of the notification unit can be switched. The switching control of the operation of the notification unit by cutting the upper wiring 22-1 will be described in detail in “Detection circuit and operation thereof” described later.

なお、このような連結構造を構成する封印固定部２１、３１は、上ケース２０及び下ケース３０にそれぞれ複数形成されている。これは、遊技機の認証確認を受ける際に必要となるからである。すなわち、遊技機の認証確認を受ける前は、一部の封印固定部２１、３１において連結ピン４０ａを押し込み挿入して上ケース２０と下ケース３０を分離不能に連結しておく。認証確認を受ける際、その連結ピン４０ａが押し込み挿入された封印固定部２１、３１に連続する開封部２２が切断され、上ケース２０が開封可能となって、認証確認が行われる。認証確認が終了すると、今度は、複数用意された封印固定部２１、３１のうち、連結ピン４０ａが未だ押し込まれていない封印固定部２１、３１にて連結ピン４０ａを押し込み挿入する。これにより、上ケース２０と下ケース３０を再度分離不能に連結することができる。 Note that a plurality of seal fixing portions 21, 31 constituting such a connection structure are formed in the upper case 20 and the lower case 30, respectively. This is because it is necessary when receiving authentication confirmation of the gaming machine. That is, before receiving the authentication confirmation of the gaming machine, the upper case 20 and the lower case 30 are connected to each other in a separable manner by pressing and inserting the connecting pin 40a in some of the seal fixing portions 21 and 31. When receiving the authentication confirmation, the opening portion 22 continuing to the sealing fixing portions 21 and 31 into which the connecting pin 40a is pushed and inserted is cut, and the upper case 20 can be opened, and the authentication confirmation is performed. When the authentication confirmation is completed, the connecting pin 40a is pushed and inserted at the sealing fixing portions 21 and 31 where the connecting pin 40a is not yet pushed out of the plurality of prepared seal fixing portions 21 and 31. Thereby, the upper case 20 and the lower case 30 can be connected again inseparably.

次に、本発明の実施形態に係るセキュリティ構造を構成する、検出回路及びその動作について、図７〜図９を参照して説明する。
図７は、検出回路の構成と、連結ピンが押し込み挿入される前の状態における検出回路の動作を示す回路図、図８は、連結ピンが押し込み挿入された状態における検出回路の動作を示す回路図、図９は、開封部が切断された状態における検出回路の動作を示す回路図である。 Next, a detection circuit and its operation constituting the security structure according to the embodiment of the present invention will be described with reference to FIGS.
FIG. 7 is a circuit diagram showing the configuration of the detection circuit and the operation of the detection circuit in a state before the connecting pin is pushed and inserted, and FIG. 8 is a circuit showing the operation of the detection circuit in the state where the connecting pin is pushed and inserted. FIG. 9 and FIG. 9 are circuit diagrams showing the operation of the detection circuit in a state where the opening portion is cut.

本実施形態に係るセキュリティ構造は、上ケース２０及び下ケース３０に形成される封印固定部２１、３１同士が連結ピン４０ａを用いて分離不能に連結されるとともに、開封部２２の切断により該開封部２２に切断の痕跡を残すように構成されている。また、本実施形態に係るセキュリティ構造は、連結ピン４０ａによる封印固定部２１、３１の連結前と連結後で検出回路５０ａに設けられた報知部の動作態様が異なることで、上ケース２０と下ケース３０が分離不能に連結されたことを確認でき、さらに、上ケース２０と下ケース３０の連結解除の前後で報知部の動作態様が異なることで、その連結解除を管理者に報知できるように構成されている。 In the security structure according to the present embodiment, the sealing fixing portions 21 and 31 formed on the upper case 20 and the lower case 30 are connected to each other using a connecting pin 40a in an inseparable manner, and the opening portion 22 is cut to open the opening portion. The section 22 is configured to leave a trace of cutting. Further, the security structure according to the present embodiment is different from the upper case 20 and the lower case in that the operation mode of the notification unit provided in the detection circuit 50a before and after the connection of the seal fixing units 21 and 31 by the connection pin 40a is different. It can be confirmed that the case 30 is connected inseparably, and the operation of the notification unit is different before and after the connection between the upper case 20 and the lower case 30 is released, so that the connection can be notified to the administrator. It is configured.

この本実施形態に係るセキュリティ構造を構成する検出回路５０ａは、制御基板ケース１０の内部（分離不能に連結された二つの部材（上ケース２０と下ケース３０）により形成される閉空間内、例えば、制御基板上など）に設けられており、図７に示すように、給電部Ｖ１からの電力の供給を受けて点灯するＬＥＤなどの発光素子（報知部）と、この発光素子が点灯可能な電流を流すための抵抗Ｒ１とを有して、これら発光素子と抵抗Ｒ１が直列に接続されており、さらに、上部接触子２１−４及び下部接触子３１−４が発光素子に並列に接続されている。
そして、上部接触子２１−４と下部接触子３１−４は、封印固定部２１、３１の内部で離間して配置されており、連結ピン４０ａが封印固定部２１、３１に押し込み挿入されると、導電部４５ａがそれら上部接触子２１−４と下部接触子３１−４との両方に接合して、上部接触子２１−４→導電部４５ａ→下部接触子３１−４の経路を形成するようになっている。つまり、導電部４５ａも、給電部から供給される電流の経路の一部を構成可能となっており、上記経路が形成されたか否かで検出回路５０ａにおける電流の流れる経路も異なることから、報知部の動作を制御でき、これにより、連結ピン４０ａによる封印固定部２１、３１の連結状態を検出できる。 The detection circuit 50a constituting the security structure according to the present embodiment has an inside of a control board case 10 (in a closed space formed by two members (an upper case 20 and a lower case 30) that are connected inseparably), for example, And a light emitting element (notification part) such as an LED that is turned on when power is supplied from the power supply unit V1, and the light emitting element can be lit as shown in FIG. The light emitting element and the resistor R1 are connected in series, and the upper contact 21-4 and the lower contact 31-4 are connected in parallel to the light emitting element. ing.
The upper contact 21-4 and the lower contact 31-4 are spaced apart from each other in the sealing fixing portions 21 and 31, and the connecting pin 40a is pushed into the sealing fixing portions 21 and 31 and inserted. The conductive portion 45a is joined to both the upper contact 21-4 and the lower contact 31-4 to form a path of the upper contact 21-4 → the conductive portion 45a → the lower contact 31-4. It has become. That is, the conductive part 45a can also constitute a part of the path of the current supplied from the power supply part, and the path through which the current flows in the detection circuit 50a differs depending on whether the path is formed. The operation of the parts can be controlled, and thereby the connection state of the seal fixing parts 21 and 31 by the connection pin 40a can be detected.

具体的には、検出回路５０ａは、次のように動作する。
例えば、連結ピン４０ａが封印固定部２１、３１に押し込まれる前の状態では、図７に示すように、連結ピン４０ａの導電部４５ａが上部接触子２１−４や下部接触子３１−４に接合していない。このため、上部接触子２１−４と下部接触子３１−４との間が電気的に接続されておらず、開放状態にあるので、発光素子に電流が流れて点灯動作する。このように点灯している発光素子を視認することで、連結ピン４０ａが未だ押し込まれておらず封印固定部２１、３１が連結されていないものと判断できる。 Specifically, the detection circuit 50a operates as follows.
For example, in a state before the connecting pin 40a is pushed into the seal fixing portions 21 and 31, the conductive portion 45a of the connecting pin 40a is joined to the upper contact 21-4 or the lower contact 31-4 as shown in FIG. Not done. For this reason, the upper contact 21-4 and the lower contact 31-4 are not electrically connected and are in an open state, so that a current flows through the light emitting element and the lighting operation is performed. By visually recognizing the light emitting element thus lit, it can be determined that the connecting pin 40a has not been pushed in yet and the sealing fixing portions 21 and 31 are not connected.

連結ピン４０ａが封印固定部２１、３１に押し込まれて封印固定部２１、３１が分離不能に連結されると、図８に示すように、連結ピン４０ａの導電部４５ａが上部接触子２１−４と下部接触子３１−４に接合し、これら上部接触子２１−４と下部接触子３１−４が導電部４５ａを介して電気的に接続される。つまり、上部接触子２１−４と下部接触子３１−４が電気スイッチの固定端子に相当し、導電部４５ａが移動端子に相当して、移動した導電部４５ａが上部接触子２１−４と下部接触子３１−４の両方に接合することにより、上部接触子２１−４→導電部４５ａ→下部接触子３１−４の経路が形成される。そして、この経路に給電部Ｖ１からの電流が流れるので、発光素子に電流が流れなくなり消灯動作する。 When the connecting pin 40a is pushed into the sealing fixing portions 21, 31, and the sealing fixing portions 21, 31 are connected inseparably, the conductive portion 45a of the connecting pin 40a is connected to the upper contact 21-4 as shown in FIG. Are joined to the lower contact 31-4, and the upper contact 21-4 and the lower contact 31-4 are electrically connected via the conductive portion 45a. That is, the upper contact 21-4 and the lower contact 31-4 correspond to the fixed terminal of the electric switch, the conductive portion 45a corresponds to the moving terminal, and the moved conductive portion 45a corresponds to the upper contact 21-4 and the lower contact. By joining both of the contacts 31-4, a path of the upper contact 21-4 → the conductive portion 45a → the lower contact 31-4 is formed. Since the current from the power supply unit V1 flows through this path, the current does not flow through the light emitting element, and the light is turned off.

これらのように、連結ピン４０ａを封印固定部２１、３１に押し込む前と押し込んだ後で、発光素子が点灯から消灯へ変化する（報知部の動作態様が異なる）ので、この変化を視認することで、連結ピン４０ａが押し込まれて封印固定部２１、３１が確実に分離不能に連結されたか否かを判断できる。 As described above, the light emitting element changes from lighting to extinguishing before and after the connecting pin 40a is pushed into the seal fixing parts 21 and 31 (the operation mode of the notification part is different). Thus, it can be determined whether or not the connecting pin 40a is pushed in and the sealing and fixing portions 21 and 31 are securely connected in a non-separable manner.

さらに、図９に示すように、開封部２２の切断に伴い上部配線２２−１が切断されると、上部接触子２１−４、導電部４５ａ、下部接触子３１−４に電流が流れなくなり、発光素子に電流が流れて点灯動作する。
このように、開封部２２が切断される前と切断された後で、発光素子が消灯から点灯へ変化する（報知部の動作態様が異なる）ことにより、開封部２２が切断された痕跡を残すことができ、その変化を視認することで開封部２２が切断されたか否かを判断できる。 Furthermore, as shown in FIG. 9, when the upper wiring 22-1 is cut along with the cutting of the opening portion 22, no current flows through the upper contact 21-4, the conductive portion 45a, and the lower contact 31-4. A current flows through the light emitting element and the lighting operation is performed.
Thus, after the opening part 22 is cut and after it is cut, the light emitting element changes from extinguishing to lighting (the operation mode of the notification part is different), thereby leaving a trace of the opening part 22 being cut. It is possible to determine whether or not the opening portion 22 has been cut by visually recognizing the change.

また、検出回路５０ａや給電部Ｖ１が制御基板ケース１の内部閉空間内に設けられているので、制御基板ケース１が開封されない限り、それら検出回路５０ａ等に対して、断線や回路変更といった不正行為を行うことができない。このことからも、報知部の動作態様の変化による制御基板ケース１の連結解除の痕跡を確実に残すことができる。 Further, since the detection circuit 50a and the power supply unit V1 are provided in the internal closed space of the control board case 1, unless the control board case 1 is opened, the detection circuit 50a and the like are illegally connected such as disconnection or circuit change. I can't act. Also from this, it is possible to reliably leave the trace of the connection release of the control board case 1 due to the change in the operation mode of the notification unit.

なお、図７〜図９に示す検出回路５０ａにおいては、発光素子を報知部として使用した。ただし、報知部は、発光素子に限るものではなく、例えば、所定の音声を発する音声出力手段や、所定の信号を他の装置へ送信する信号送信手段などを使用することもできる。 In addition, in the detection circuit 50a shown in FIGS. 7-9, the light emitting element was used as an alerting | reporting part. However, the notification unit is not limited to the light emitting element, and for example, an audio output unit that emits a predetermined sound, a signal transmission unit that transmits a predetermined signal to another device, or the like can be used.

また、検出回路５０ａの構成は、図７〜図９に示す構成に限るものではなく、例えば、図１０に示すように、インバータを用いたロジック回路で構成することもできる。
この検出回路ｂは、次のように動作する。例えば、連結ピン４０ａの押し込み挿入前は、検出回路ｂの入力がＬとなり、抵抗Ｒ１側にＨが出力されて、発光素子（ＬＥＤ）が点灯する。連結ピン４０ａが押し込み挿入されると、検出回路ｂの入力がＨとなり、抵抗Ｒ１側にＬが出力されて、発光素子が消灯する。開封部２２が切断されると、検出回路ｂの入力がＬとなり、抵抗Ｒ１側にＨが出力されて、発光素子が点灯する。
このように、検出回路ｂも、図７〜図９に示す検出回路ａと同様の動作をするため、封印固定部２１、３１が分離不能に連結されたことを検出したり、開封部２２が切断された痕跡を残したりすることができる。 Further, the configuration of the detection circuit 50a is not limited to the configuration illustrated in FIGS. 7 to 9, and may be configured with a logic circuit using an inverter as illustrated in FIG. 10, for example.
The detection circuit b operates as follows. For example, before the insertion of the connecting pin 40a, the input of the detection circuit b becomes L, H is output to the resistor R1 side, and the light emitting element (LED) is lit. When the connecting pin 40a is pushed in and inserted, the input of the detection circuit b becomes H, L is output to the resistor R1 side, and the light emitting element is turned off. When the opening part 22 is cut, the input of the detection circuit b becomes L, H is output to the resistor R1 side, and the light emitting element is turned on.
Thus, since the detection circuit b also operates in the same manner as the detection circuit a shown in FIGS. 7 to 9, it is detected that the seal fixing parts 21 and 31 are connected inseparably, or the opening part 22 is The cut trace can be left.

さらに、図７〜図９に示す検出回路５０ａにおいては、連結ピン４０ａを封印固定部２１、３１に押し込む前と押し込んだ後で発光素子を点灯から消灯へ変化させ、開封部２２が切断される前と切断された後で発光素子を消灯から点灯へ変化させるようにしたが、発光素子の動作態様は、これに限るものではなく、例えば、図１１に示す検出回路５０ｃを用いることにより、連結ピン４０ａを封印固定部２１、３１に押し込む前と押し込んだ後で発光素子を消灯から点灯へ変化させ、開封部２２が切断される前と切断された後で発光素子を点灯から消灯へ変化させるようにすることもできる。 Further, in the detection circuit 50a shown in FIGS. 7 to 9, the light emitting element is changed from lighting to extinguishing before and after the connecting pin 40a is pushed into the sealing fixing parts 21 and 31, and the opening part 22 is cut. Although the light emitting element is changed from the off state to the on state after being cut off before and after being disconnected, the operation mode of the light emitting element is not limited to this. For example, by using the detection circuit 50c shown in FIG. Before and after the pin 40a is pushed into the seal fixing parts 21 and 31, the light emitting element is changed from light-off to lighting, and before the opening part 22 is cut and after it is cut, the light-emitting element is changed from lighting to light-off. It can also be done.

また、発光素子は、図７〜図９においては、検出回路５０ａに設けたが、これに限るものではなく、例えば、図１２に示すように、連結ピン４０ｂの内部に設けることができる。
この場合、導電部４５ｂの構成としては、発光素子４５ｂ−５の一方の端子と上部接点部４５ｂ−１との間をジャンパ線４５ｂ−６で接続し、発光素子４５ｂ−５の他方の端子と下部接点部４５ｂ−２との間を極細裸リード線４５ｂ−７で接続することで、上部接点部４５ｂ−１と発光素子４５ｂ−５と下部接点部４５ｂ−２との間を電気的に導通可能とすることができる。 7 to 9, the light emitting element is provided in the detection circuit 50a. However, the present invention is not limited to this. For example, as shown in FIG. 12, the light emitting element can be provided in the connection pin 40b.
In this case, as a configuration of the conductive portion 45b, one terminal of the light emitting element 45b-5 and the upper contact portion 45b-1 are connected by a jumper wire 45b-6, and the other terminal of the light emitting element 45b-5 is connected. By electrically connecting the lower contact portion 45b-2 with the bare bare lead wire 45b-7, the upper contact portion 45b-1, the light emitting element 45b-5, and the lower contact portion 45b-2 are electrically connected. Can be possible.

この導電部４５ｂを連結ピン４５ｂに嵌め込んだ場合、発光素子４５ｂ−５は、軸部４２の側面から頭部４１の上面中央にかけてＬ字形状に穿設された収納孔４６にジャンパ線４５ｂ−６とともに収納され、極細裸リード線４５ｂ−７は、外傷を防ぐために、軸部４２の側面に形成された溝部（図示せず）に埋め込むように配置される。そして、頭部４１の上面中央に位置する収納孔４６の開口には透光性材料で形成された窓部材４７が装着されており、発光素子４５ｂ−５の発光を外部から視認可能になっている。 When the conductive portion 45b is fitted into the connecting pin 45b, the light emitting element 45b-5 is jumpered into the storage hole 46 formed in an L shape from the side surface of the shaft portion 42 to the center of the upper surface of the head portion 41. 6 and the bare bare lead wire 45b-7 is disposed so as to be embedded in a groove (not shown) formed on the side surface of the shaft portion 42 in order to prevent trauma. A window member 47 made of a translucent material is attached to the opening of the housing hole 46 located in the center of the upper surface of the head 41, so that the light emitted from the light emitting element 45b-5 can be visually recognized from the outside. Yes.

さらに、発光素子４５ｂ−５を内蔵した連結ピン４０ｂを用いる場合、検出回路５０ｄは、図１３に示すように、給電部Ｖ１と上部接触子２１−４との間に抵抗Ｒ１を直列に接続し、下部接触子３１−４を接地する構成としている。
この構成において、例えば、連結ピン４０ｂが封印固定部２１、３１に押し込まれる前の状態では、導電部４５ｂが上部接触子２１−４及び下部接触子３１−４に接合せず、これら上部接触子２１−４と導電部４５ｂとの間、及び、導電部４５ｂと下部接触子３１−４との間がそれぞれ開放状態にあるので、発光素子４５ｂ−５に電流が流れず消灯する。 Further, when the connecting pin 40b incorporating the light emitting element 45b-5 is used, the detection circuit 50d connects a resistor R1 in series between the power feeding portion V1 and the upper contact 21-4 as shown in FIG. The lower contact 31-4 is grounded.
In this configuration, for example, in a state before the connecting pin 40b is pushed into the seal fixing portions 21 and 31, the conductive portion 45b is not joined to the upper contact 21-4 and the lower contact 31-4, and these upper contacts. 21-4 and the conductive portion 45b and between the conductive portion 45b and the lower contact 31-4 are in an open state, so that no current flows through the light emitting element 45b-5 and the light is turned off.

また、連結ピン４０ｂが封印固定部２１、３１に押し込まれて封印固定部２１、３１が分離不能に連結されると、上部接触子２１−４と下部接触子３１−４が導電部４５ｂを介して電気的に接続され、発光素子４５ｂ−５に電流が流れて点灯する（図１３、図１４参照）。
このように、連結ピン４０ｂを封印固定部２１、３１に押し込む前と押し込んだ後で、発光素子が消灯から点灯へ変化する（報知部の動作態様が異なる）ので、この変化を視認することで、連結ピン４０ｂが押し込まれて封印固定部２１、３１が確実に分離不能に連結されたか否かを判断できる。 Further, when the connecting pin 40b is pushed into the sealing fixing portions 21 and 31 and the sealing fixing portions 21 and 31 are connected inseparably, the upper contact 21-4 and the lower contact 31-4 are connected via the conductive portion 45b. Are electrically connected, and a current flows through the light emitting element 45b-5 to light it (see FIGS. 13 and 14).
As described above, the light emitting element changes from being turned off to being lit before and after the connecting pin 40b is pushed into the seal fixing parts 21 and 31 (the operation mode of the notification part is different). Thus, it can be determined whether or not the connecting pin 40b is pushed in and the sealing and fixing portions 21 and 31 are securely connected to each other.

さらに、開封部２２の切断により上部配線２２−１が切断されると、上部接触子２１−４、導電部４５ｂ、下部接触子３１−４に電流が流れなくなり、発光素子４５ｂ−５に電流が流れなくなり消灯する。
このように、開封部２２が切断される前と切断された後で、発光素子が点灯から消灯へ変化する（報知部の動作態様が異なる）ので、開封部２２が切断された痕跡を残すことができ、その変化を視認することで開封部２２が切断されたか否かを判断できる。 Further, when the upper wiring 22-1 is cut by cutting the unsealed portion 22, no current flows through the upper contact 21-4, the conductive portion 45b, and the lower contact 31-4, and no current flows through the light emitting element 45b-5. No longer flows and turns off.
Thus, since the light emitting element changes from lighting to extinguishing before and after the opening part 22 is cut (the operation mode of the notification part is different), leaving a trace of the opening part 22 being cut. It is possible to determine whether or not the opening portion 22 has been cut by visually recognizing the change.

なお、連結ピン４０ｂの頭部４１や軸部４２、あるいは連結ピン４０ｂの全体を透光性の材料で形成することにより、発光素子４５ｂ−５の点灯を外部から容易に視認することができる。 It should be noted that the lighting of the light emitting element 45b-5 can be easily visually recognized from the outside by forming the head 41 and the shaft portion 42 of the connecting pin 40b or the entire connecting pin 40b with a light-transmitting material.

以上説明したように、本実施形態のセキュリティ構造によれば、連結ピンによる上ケースと下ケースの連結前と連結後で報知部の動作態様が異なるので、それら上ケースと下ケースが本当に分離不能な封止状態となったかどうかを判断できる。
また、開封部の切断に伴い、この開封部に配設された上部配線も切断されて、発光素子が点灯又は消灯するので、この発光素子の動作態様の変化によって不正行為の痕跡を残し、遊技機点検の際の目視検査を容易に行うことができる。 As described above, according to the security structure of the present embodiment, the operation mode of the notification unit is different before and after the connection between the upper case and the lower case by the connection pin, so that the upper case and the lower case are not really separable. It can be determined whether or not the sealed state has been achieved.
Further, as the opening portion is cut, the upper wiring disposed in the opening portion is also cut and the light emitting element is turned on or off, so that a change in the operation mode of the light emitting element leaves a trace of fraud, and the game Visual inspection during machine inspection can be easily performed.

さらに、検出回路の構成を、発光素子などの報知部への給電を制御する簡単な構成としたので、制御基板を破断してこの制御基板に負担をかけることがなく、さらに、ＣＰＵや記憶装置を搭載した制御回路に負担をかけることがない。
しかも、連結ピンを完全に封印固定部に押し込み挿入したときにのみ発光素子への導通（又は非導通）を可能にしているので、誤動作がほとんどない。 Furthermore, since the configuration of the detection circuit is a simple configuration for controlling the power supply to the notification unit such as a light emitting element, the control board is not broken and does not place a burden on the control board. There is no burden on the control circuit equipped with
In addition, since the connection (or non-conduction) to the light emitting element is enabled only when the connecting pin is completely pushed into and inserted into the seal fixing portion, there is almost no malfunction.

また、開封部の切断ではなく、連結ピンを軸芯方向からドリルなどで破壊したり、又は、連結ピンの軸部を剪断したりするなどして、上ケースを開封する不正行為があった場合でも、連結ピンの導電部と各接触子との導通が断たれるので、発光素子の動作態様が変化する。これにより、不正の痕跡を容易に目視確認することができる。 In addition, when there is an illegal act of opening the upper case, such as by breaking the connecting pin with a drill from the axial direction, or by shearing the connecting pin shaft, instead of cutting the opening part However, since the conduction between the conductive portion of the connecting pin and each contactor is interrupted, the operation mode of the light emitting element changes. Thereby, the trace of fraud can be easily visually confirmed.

以上、本発明のセキュリティ構造の好ましい実施形態について説明したが、本発明に係るセキュリティ構造は上述した実施形態にのみ限定されるものではなく、本発明の範囲で種々の変更実施が可能であることは言うまでもない。
例えば、上述した実施形態では、遊技機に設けられる制御基板用のケースを対象としたセキュリティ構造について説明したが、遊技機に限るものではなく、例えば、遊技に使用されるパチンコ玉やメダルなどの遊技媒体を遊技者に貸出す遊技媒体貸出機、遊技媒体の数量を計数する計数機、遊技機ごとに設置され遊技機からの信号を中継する台コンピュータ、複数の遊技機で構成される遊技機島に設置され台コンピュータとホールコンピュータとの間で信号の中継を行う島コンピュータ、遊技機ごとに設置され遊技に関する各種データを表示する呼出しランプなど、遊技場に設置される各種装置において、これら各種装置に設けられた制御基板を、装置内の固定部材に連結ピンを介して分離不能（取り外し不能）に連結（固定）する連結構造にも、本発明のセキュリティ構造を適用することができる。 The preferred embodiment of the security structure of the present invention has been described above, but the security structure according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. Needless to say.
For example, in the above-described embodiment, the security structure for the case for the control board provided in the gaming machine has been described. However, the security structure is not limited to the gaming machine, for example, a pachinko ball or a medal used for gaming. A game media lending machine that rents game media to a player, a counter that counts the number of game media, a stand computer that is installed in each game machine and relays signals from the game machine, and a game machine composed of a plurality of game machines These various types of devices installed in the game hall, such as island computers installed on the island that relay signals between the base computer and the hall computer, and call lamps installed on each gaming machine that display various data relating to games A connection structure for connecting (fixing) a control board provided in the device to a fixing member in the device in a non-separable (non-removable) manner via a connection pin. Also, it is possible to apply the security structure of the present invention.

また、本発明のセキュリティ構造は、上述した実施形態のように、所定の基板を収納する上ケース２０と下ケース３０を分離不能に連結する連結構造だけでなく、例えば、孔部を有する所定の基板を、孔部を有する所定の固定部材に連結ピンを介して直接固定する連結構造にも適用可能である。つまり、本発明のセキュリティ構造は、連結ピンを介して二つの部材を分離不能に連結する連結構造であれば、全てに適用できる。 In addition, the security structure of the present invention is not limited to a connection structure in which the upper case 20 and the lower case 30 that store a predetermined substrate are connected to each other in a non-separable manner, as in the above-described embodiment. The present invention is also applicable to a connection structure in which the substrate is directly fixed to a predetermined fixing member having a hole via a connection pin. That is, the security structure of the present invention can be applied to any connection structure in which two members are connected in a non-separable manner via a connection pin.

さらに、連結ピンに搭載された発光素子の色を連結ピンごとに変えることにより、上ケースの開封履歴を明確にすることができる。例えば、第一の連結ピンに搭載された発光素子の色を白色、第二の連結ピンに搭載された発光素子の色を赤色とする。遊技機の認証確認前（出荷時）は、第一の連結ピンにより上ケースと下ケースを連結封印し、認証確認終了後（不正検査後）、遊技機へ取り付ける際には、第二の連結ピンにより上ケースと下ケースを連結封印する。これにより、白色の発光素子が点灯していれば認証確認前であることがわかり、赤色の発光素子が点灯していれば認証確認後であることがわかり、すべての発光素子が消灯していれば不正行為により開封部が切断されたことがわかる。 Furthermore, the opening history of the upper case can be clarified by changing the color of the light emitting element mounted on the connection pin for each connection pin. For example, the color of the light emitting element mounted on the first connecting pin is white, and the color of the light emitting element mounted on the second connecting pin is red. Before confirming the gaming machine (when shipped), the upper case and the lower case are connected and sealed with the first connecting pin, and after the confirmation is confirmed (after the fraud inspection), when attaching to the gaming machine, the second connection The upper case and the lower case are connected and sealed with pins. Thus, if the white light-emitting element is lit, it indicates that the authentication has not been confirmed, and if the red light-emitting element is lit, it indicates that the authentication has been confirmed, and all the light-emitting elements are turned off. For example, it can be seen that the unsealed part has been cut by fraud.

また、上述した実施形態では、連結ピンは、樹脂製としたが、樹脂製に限るものではなく、導電性材料で形成することができる。この場合、導電部は不要となり、この連結ピン本体により、上部接触子と下部接触子とを電気的に接続することができる。 In the above-described embodiment, the connection pin is made of resin, but is not limited to resin, and can be formed of a conductive material. In this case, the conductive portion is not necessary, and the upper contact and the lower contact can be electrically connected by the connecting pin body.

さらに、発光素子を下ケースの封印固定部の丸孔の底部に設けるとともに、連結ピン本体を透光性材料で形成し、さらに、検出回路の構成を、図１１に示すように、連結ピンによる封印固定部の連結により発光素子が点灯し、開封部の切断により消灯するようにする。このようにすれば、複数の連結ピンのうち、封印固定部に押し込まれた連結ピンの先端は、発光素子に接近するので、透光性を有する連結ピン自体が明るく光る。これに対し、封印固定部に押し込まれていない連結ピンは、発光素子が点灯しないため、連結ピン自体も光らない。これにより、連結ピンが上ケースと下ケースを分離不能に連結しているか否かを判断できる。しかも、開封部が切断されると、発光素子が消灯し、連結ピン自体も光らなくなるので、開封部が切断された痕跡を残すことができる。 Further, the light emitting element is provided at the bottom of the round hole of the sealing fixing portion of the lower case, the connecting pin main body is formed of a translucent material, and the configuration of the detection circuit is based on the connecting pin as shown in FIG. The light emitting element is turned on by the connection of the seal fixing part, and is turned off by cutting the opening part. If it does in this way, since the front-end | tip of the connection pin pushed into the sealing fixing | fixed part among several connection pins will approach a light emitting element, the connection pin itself which has translucency will shine brightly. On the other hand, since the light emitting element does not light the connection pin which is not pushed into the seal fixing part, the connection pin itself does not shine. Accordingly, it can be determined whether or not the connecting pin connects the upper case and the lower case inseparably. In addition, when the opening portion is cut, the light emitting element is turned off and the connecting pin itself does not shine, so that a trace of the opening portion being cut can be left.

そして、上ケースの封印固定部の壁部に配置される上部接触子の上面には、内周に沿って凸部を連続的又は間歇的に形成することができる。この凸部を有することで、連結ピンの導電部の上部接点部との接合がより確実なものとなる。
同様に、下ケースの封印固定部の壁部に配置される下部接触子の下面には、内周に沿って凸部を連続的又は間歇的に形成することができる。この凸部を有することで、連結ピンの導電部の下部接点部との接合をより確実なものとすることができる。 And a convex part can be continuously or intermittently formed in the upper surface of the upper contact arranged on the wall part of the sealing fixing part of the upper case along the inner periphery. By having this convex part, joining with the upper contact part of the electroconductive part of a connection pin becomes more reliable.
Similarly, a convex portion can be formed continuously or intermittently along the inner periphery on the lower surface of the lower contact arranged on the wall portion of the seal fixing portion of the lower case. By having this convex part, joining with the lower contact part of the electroconductive part of a connection pin can be made more reliable.

本発明は、遊技機に取り付けられる遊技機用基板ケースに広く利用することができる。 The present invention can be widely used for gaming machine board cases attached to gaming machines.
