Description

本発明は、遊技機における回路基板を収納する基板ケースに関する。 The present invention relates to a board case for storing a circuit board in a gaming machine.

従来、上記基板ケースとして、回路基板に対する改造等の不正行為を防止するために、ケースの隙間から工具が挿入されたとしても、回路基板に触れることができないような工夫を凝らしたものが知られている。このような基板ケースにおいては、ケース本体部材とケース蓋部材とを備え、これらを組み付けることにより内部に形成された収納空間に回路基板を収納する構成にされているものがある（例えば、特許文献１参照）。 Conventionally, as the above-mentioned board case, in order to prevent illegal acts such as modification to the circuit board, even if a tool is inserted from the gap of the case, an ingenuity that prevents touching the circuit board is known. ing. Such a substrate case includes a case main body member and a case lid member, and has a configuration in which a circuit board is stored in a storage space formed therein by assembling them (for example, Patent Documents). 1).

この基板ケースにおいて回路基板を収納空間に収納する際には、回路基板は、電子部品が実装された実装面側をケース蓋部材に向けた状態で、回路基板の裏面（実装面とは反対側の面）を覆う内部カバーとともに、例えば基板取付ネジ等の基板固定部材を用いてケース蓋部材に取り付けられる。そして、回路基板が備えられたケース蓋部材は、内部カバー側がケース本体部材に組み付けられた状態で、ケース固定部材によりケース本体部に対して固定される。 When the circuit board is stored in the storage space in this board case, the circuit board is placed on the back surface of the circuit board (opposite to the mounting surface) with the mounting surface side on which the electronic components are mounted facing the case lid member. Attached to the case lid member using a substrate fixing member such as a substrate mounting screw together with an inner cover covering The case lid member provided with the circuit board is fixed to the case main body by the case fixing member in a state where the inner cover side is assembled to the case main body member.

このような基板ケースによれば、回路基板が内部カバーに覆われた状態になるため、針金や工具等の道具がケース本体部とケース蓋部材との隙間から挿入されたとしても、回路基板上の電子部品に道具が到達することを防止することができる。
特開２００４−２８３４４３号公報 According to such a board case, since the circuit board is covered with the inner cover, even if a tool such as a wire or a tool is inserted from the gap between the case body and the case lid member, It is possible to prevent the tool from reaching the electronic component.
JP 2004-283443 A

ところで近年においては、回路基板に対する不正行為として、基板ケースを開封し、回路基板上の電子部品を交換するという大胆な手口が報告されている。ここで、上記基板ケースにおいて、基板ケースが開封された状態（つまり、ケース本体部材とケース蓋部材とを分離した状態）では、基板固定部材を取り外すだけで、内部カバー、回路基板、およびケース蓋部材が分離する構成にされている。 By the way, in recent years, as a fraudulent act against the circuit board, a bold technique of opening the board case and replacing electronic components on the circuit board has been reported. Here, in the above-mentioned substrate case, when the substrate case is opened (that is, in a state where the case main body member and the case lid member are separated), the internal cover, the circuit board, and the case lid are simply removed by removing the substrate fixing member. The members are separated.

このため、この基板ケースにおいては、基板ケースが開封されてしまえば、短時間で回路基板を取り外すことができ、電子部品の交換を容易に実施することができるという問題点があった。 For this reason, in this board case, once the board case is opened, the circuit board can be removed in a short time, and the electronic components can be easily replaced.

そこで、このような問題点を鑑み、遊技機における回路基板を収納する基板ケースにおいて、基板ケースが開封されたとしても、短時間で回路基板を取り外すことができないようにすることを本発明の目的とする。 Accordingly, in view of such problems, it is an object of the present invention to prevent a circuit board from being removed in a short time even when the board case is opened in a board case for storing a circuit board in a gaming machine.

即ち、請求項１に記載の基板ケースにおいては、基板被覆部材を取り外すことなく基板固定部材を取り外したとしても、基板被覆部材が回路基板の裏面側の全面を覆っているので回路基板を取り外すことができない。また、請求項２に記載の基板ケースにおいても、基板固定部材が基板被覆部材に覆われた状態になっているため、基板被覆部材を取り外すことなく回路基板を取り外すことができない。 That is, in the board case according to claim 1, even if the board fixing member is removed without removing the board covering member, the circuit board is removed because the board covering member covers the entire back surface of the circuit board. I can't. In the substrate case according to the second aspect, since the substrate fixing member is covered with the substrate covering member, the circuit board cannot be removed without removing the substrate covering member.

このため、基板ケースを不正に開封しようとする第三者が回路基板に触れるためには、ケース固定部材、基板固定部材、および基板被覆固定部材の全ての固定部材を取り外さなければならない。 For this reason, in order for a third party who tries to open the substrate case to touch the circuit board illegally, all the fixing members of the case fixing member, the substrate fixing member, and the substrate covering fixing member must be removed.

従って、この第三者が回路基板を触れるまでには時間が掛かるため、基板ケースを不正に開封しようとする第三者の気力を減退させることができる。よって、回路基板が電子部品の交換や改造等の不正行為を受け難くすることができる。 Therefore, since it takes time for the third party to touch the circuit board, it is possible to reduce the power of the third party who attempts to open the board case illegally. Therefore, it is possible to make the circuit board less susceptible to unauthorized acts such as replacement or modification of electronic components.

なお、「封止」とは、「開口を閉鎖すること」、「封じ込めること」を意味し、本発明において「回路基板を前記収納空間に封止する」とは、「第１ケース部材および第２ケース部材による開口を閉鎖すること」、「回路基板を収納空間に封じ込めること」を意味する。 Note that “sealing” means “closing the opening” and “containing”, and in the present invention, “sealing the circuit board in the storage space” means “first case member and first sealing member”. 2 means closing the opening by the case member, and “sealing the circuit board in the storage space”.

また、請求項１または請求項２に記載の基板ケースは、

At least one of the fixed member of said board fixing member and the substrate cover fixing member, that is configured as a sealing means can not be removed unless destroying the fixing member.

このような基板ケースによれば、封止手段を破壊しなければ電子部品に触れることができないので、封止手段の破壊に手間が掛かる分だけ電子部品が第三者に触れられ難くすることができる。また、仮に電子部品が触れられてしまった場合には、封止手段は破壊された状態になるので、当該基板ケースの管理者は電子部品が第三者によって触れられたことを容易に識別することができる。 According to such a substrate case, since the electronic component cannot be touched unless the sealing means is destroyed, the electronic component can be made difficult to be touched by a third party as much as it takes time to destroy the sealing means. it can. In addition, if the electronic component is touched, the sealing means is destroyed, so that the manager of the board case easily identifies that the electronic component has been touched by a third party. be able to.

以下に本発明にかかる実施の形態を図面と共に説明する。

[Example 1]
FIG. 1 is a perspective view of a board case (hereinafter simply referred to as “board case”) of the gaming machine according to the present embodiment, and FIG. 2 is an exploded perspective view of the board case. The board case is attached to the center of the back side of the board surface of a gaming machine (not shown) such as a pachinko machine, and the circuit board in the board case is connected to the image control board, the prize ball control board, etc. via a connector. It is.

図１に示すように、基板ケース１は、遊技機に直接取り付けられる略長方形状のベース部材１０（第１ケース部材）と、ベース部材１０に組み付けられる長方形状のカバー部材２０（第２ケース部材）とを備えている。これらベース部材１０およびカバー部材２０は、共に透明の合成樹脂から形成されている。 As shown in FIG. 1, the substrate case 1 includes a substantially rectangular base member 10 (first case member) that is directly attached to the gaming machine, and a rectangular cover member 20 (second case member) that is assembled to the base member 10. ). Both the base member 10 and the cover member 20 are made of a transparent synthetic resin.

まず、カバー部材２０について説明する。図２に示すように、カバー部材２０は無蓋箱状の本体２１を有し、その内部には、遊技機を制御する電子部品が実装された回路基板６１が螺合固定される。そして、この状態からカバー部材２０をベース部材１０に組み付けた状態で、後に詳述する固定部材５０（ケース固定部材）によりこれらを固定することにより、カバー部材２０とベース部材１０との間に形成される収納空間に回路基板６１が封止されるように構成されている。なお、「封止」とは、「開口を閉鎖すること」、「封じ込めること」を意味する。 First, the cover member 20 will be described. As shown in FIG. 2, the cover member 20 has an uncovered box-shaped main body 21 in which a circuit board 61 on which electronic components for controlling the gaming machine are mounted is screwed and fixed. Then, in a state where the cover member 20 is assembled to the base member 10 from this state, these are fixed by a fixing member 50 (case fixing member) which will be described in detail later, thereby forming between the cover member 20 and the base member 10. The circuit board 61 is sealed in the storage space. “Sealing” means “closing the opening” and “containing”.

ここで、カバー部材２０の詳細について図２および図３（ａ）を用いて説明する。なお、図３（ａ）は、カバー部材２０を示す背面図である。カバー部材２０は上下対称かつ左右対称に構成されており、本体２１の左右側面に上下方向に等間隔に設けられ外方に延出する複数の補強リブ２２を介して、本体２１の側面に平行に延びる平板状の透明な合成樹脂からなる側壁部材２３が設けられている。 Here, the detail of the cover member 20 is demonstrated using FIG. 2 and FIG. 3 (a). FIG. 3A is a rear view showing the cover member 20. The cover member 20 is configured to be vertically and horizontally symmetrical, and is parallel to the side surface of the main body 21 via a plurality of reinforcing ribs 22 provided at equal intervals in the vertical direction on the left and right side surfaces of the main body 21 and extending outward. A side wall member 23 made of a transparent transparent resin plate is provided.

そして、隣接する補強リブ２２の間に位置する側壁部材２３の内面からは、本体２１に向かって支持リブ２４が延設されており、その先端に円筒状の筒状部材２５が連設されている。この筒状部材２５は、内部にベース部材１０側に小径化する段差部を有し（後述する）、カバー部材２０において左右対称に４個ずつ計８個設けられている。 And from the inner surface of the side wall member 23 located between the adjacent reinforcement ribs 22, the support rib 24 is extended toward the main body 21, and the cylindrical cylindrical member 25 is continuously provided at the tip. Yes. The cylindrical member 25 has a stepped portion with a reduced diameter on the side of the base member 10 inside (described later), and a total of eight cylindrical members 25 are provided in the cover member 20, four in a symmetrical manner.

また、本体２１の上下側面からは、外方に延びるフランジ部２６がそれぞれ設けられ、このフランジ部２６の先端縁には、ベース部材１０との重合方向に延出した側壁部２７が連設されている。そして、この側壁部２７の外面の左右方向に等間隔に設けられ外方に延出する複数の補強リブ２８を介して、本体２１の側面に平行に延びる平板状のガイド部材２９が設けられている。なお、フランジ部２６には、回路基板６１に設けられたコネクタ群を外部に露出させるための複数のコネクタ窓２６ａが形成されている。 Further, outwardly extending flange portions 26 are respectively provided from the upper and lower side surfaces of the main body 21, and a side wall portion 27 extending in the overlapping direction with the base member 10 is connected to the front end edge of the flange portion 26. ing. A flat guide member 29 extending in parallel with the side surface of the main body 21 is provided via a plurality of reinforcing ribs 28 provided at equal intervals in the left-right direction of the outer surface of the side wall portion 27 and extending outward. Yes. The flange portion 26 is formed with a plurality of connector windows 26a for exposing a connector group provided on the circuit board 61 to the outside.

そして、側壁部２７とガイド部材２９との間には、互いに隣接する一方の補強リブ２８の側壁部２７側から当該側壁部２７に沿って延びる４つの係合部３１が突設され、隣接する他方の補強リブ２８とこの係合部３１との間に、後述するベース部材１０側の係合部を挿入してスライドさせるための鈎状の開口部３２が形成されている。なお、この係合部３１は、隣接する補強リブ２８に対し一つおきに設けられ、係合部３１が設けられてない補強リブ２８間は、板状の架橋部材３３により閉口されている。 And between the side wall part 27 and the guide member 29, the four engaging parts 31 extended along the said side wall part 27 from the side wall part 27 side of the mutually adjacent one of the reinforcement ribs 28 protrude, and are adjacent. Between the other reinforcing rib 28 and the engaging portion 31, a hook-shaped opening portion 32 is formed for inserting and sliding an engaging portion on the base member 10 side described later. In addition, this engaging part 31 is provided every other reinforcement rib 28, and between the reinforcing ribs 28 where the engaging part 31 is not provided is closed by a plate-like bridging member 33.

さらに、上述したフランジ部２６は本体２１の左右にも延出し、上記補強リブ２２のうち上下の両端に配置されたものにそれぞれ連設してフランジ部３４を構成する。そして、図２に示すように、この左右に延出した上下のフランジ部３４の部分をそれぞれ架橋する態様で一対の被覆部材３５が装着されている。 Further, the flange portion 26 described above also extends to the left and right of the main body 21, and the flange portion 34 is configured to be connected to the reinforcing ribs 22 disposed at both the upper and lower ends. And as shown in FIG. 2, a pair of coating | coated member 35 is mounted | worn with the aspect which bridge | crosslinks the part of the up-and-down flange part 34 extended to this right and left, respectively.

これら被覆部材３５は、ベース部材１０側に開口する無蓋箱状に形成され、上記フランジ部３４に対向して立設された二つの支持部３６に挟持される態様で、当該フランジ部３４に螺合固定される。そして、その各々が上記４つの筒状部材２５を被覆してこれらを外部から遮蔽している。 These covering members 35 are formed in a lidless box shape that opens to the base member 10 side, and are screwed into the flange portion 34 in such a manner that the covering members 35 are sandwiched between two support portions 36 erected facing the flange portion 34. Fixed. And each of them covers the four cylindrical members 25 to shield them from the outside.

さらに、被覆部材３５の上壁部３５ａ（図７参照）において各固定部材５０に対向する位置には、所定の棒状部材を挿通可能な小孔３５ｃが穿設されており、この小孔３５ｃに棒状部材を挿通して、いずれかの固定部材５０をベース部材１０側へ押圧することができるようになっている。 Further, a small hole 35c through which a predetermined rod-shaped member can be inserted is formed in a position facing the fixing member 50 in the upper wall portion 35a (see FIG. 7) of the covering member 35. One of the fixing members 50 can be pressed toward the base member 10 by inserting the rod-shaped member.

また、図３（ａ）に示すように、カバー部材２０の本体２１の隅部には、４つの基板固定ボス３７および４つのカバー固定ボス３８が設けられており、図２に示すように、基板固定ボス３７に回路基板６１が固定されるとともに、カバー固定ボス３８に内部カバー６０（基板被覆部材）が固定される。なお、カバー固定ボス３８は、基板固定ボス３７よりもカバー部材２０の外周側に配置されており、回路基板６１は４つのカバー固定ボス３８に囲まれた領域の内側に収納されることになる。 3A, four substrate fixing bosses 37 and four cover fixing bosses 38 are provided at the corners of the main body 21 of the cover member 20. As shown in FIG. The circuit board 61 is fixed to the board fixing boss 37, and the inner cover 60 (board covering member) is fixed to the cover fixing boss 38. The cover fixing boss 38 is disposed on the outer peripheral side of the cover member 20 with respect to the substrate fixing boss 37, and the circuit board 61 is accommodated inside an area surrounded by the four cover fixing bosses 38. .

ここで、内部カバー６０は、その形状は略長方形に形成されている。また、内部カバー６０は、万一、内部の回路基板６１に不正が施された場合に、その不正を基板ケース１を開封することなく外部から視認することができるように、カバー部材２０と同様に、例えばアクリル板等の透明な素材から構成されている。 Here, the inner cover 60 is formed in a substantially rectangular shape. Also, the internal cover 60 is similar to the cover member 20 so that in the unlikely event that the internal circuit board 61 is cheated, the cheating can be seen from the outside without opening the board case 1. Further, it is made of a transparent material such as an acrylic plate.

次に、回路基板６１の取付の詳細について図４および図５を用いて説明する。図４（ａ）は図１のＡ−Ａ断面図であってベース部材１０とカバー部材２０との組み付け状態を示す説明図、図４（ｂ）はその分解図である。また、図５は回路基板６１を固定する際に使用される特殊ネジ７１（基板固定部材）を表す説明図である。 Next, details of mounting the circuit board 61 will be described with reference to FIGS. 4 and 5. 4A is an AA cross-sectional view of FIG. 1 and is an explanatory view showing an assembled state of the base member 10 and the cover member 20, and FIG. 4B is an exploded view thereof. FIG. 5 is an explanatory view showing a special screw 71 (substrate fixing member) used when fixing the circuit board 61.

回路基板６１は、図４（ａ）に示すように、自身に特殊ネジ７１が挿通された状態で、この特殊ネジ７１をカバー部材２０の基板固定ボス３７に螺合することによって固定される。この際、回路基板６１は、図示しない電子部品群が設けられた側の面（実装面）がカバー部材２０における内側（図４（ａ）では上側）を向くように固定される。 As shown in FIG. 4A, the circuit board 61 is fixed by screwing the special screw 71 to the board fixing boss 37 of the cover member 20 with the special screw 71 inserted therethrough. At this time, the circuit board 61 is fixed so that the surface (mounting surface) on which the electronic component group (not shown) is provided faces the inner side (upper side in FIG. 4A) of the cover member 20.

また、内部カバー６０は、図４（ａ）に示すように、回路基板６１がカバー部材２０に取り付けられた状態で、回路基板６１の全面（特殊ネジ７１が装着された部位を含む）を覆うように固定される。具体的には、内部カバー６０は、自身に通常ネジ７２（基板被覆固定部材）が挿通された状態で、この通常ネジ７２をカバー部材２０のカバー固定ボス３８に螺合することによって固定される。 Further, as shown in FIG. 4A, the inner cover 60 covers the entire surface of the circuit board 61 (including a portion where the special screw 71 is attached) in a state where the circuit board 61 is attached to the cover member 20. To be fixed. Specifically, the inner cover 60 is fixed by screwing the normal screw 72 into the cover fixing boss 38 of the cover member 20 with the normal screw 72 (substrate covering fixing member) inserted therein. .

ここで、回路基板６１を固定するための特殊ネジ７１と、内部カバー６０を固定するための通常ネジ７２とは、異なるヘッド形状を有する。つまり、通常ネジ７２のヘッド形状が、例えば通常のマイナスドライバによって回動可能な−形状（一直線状）の溝部を備えているのに対して、特殊ネジ７１のヘッド形状は、図５に示すように、通常のプラスドライバによって回動可能な＋形状の溝部７１ａに加えて、この溝部７１ａの中央にこの溝部から突出する突起部７１ｂを備えている。 Here, the special screw 71 for fixing the circuit board 61 and the normal screw 72 for fixing the inner cover 60 have different head shapes. That is, the head shape of the special screw 71 includes a minus-shaped (straight line) groove portion that can be rotated by, for example, a normal minus driver, whereas the head shape of the special screw 71 is as shown in FIG. In addition to a + -shaped groove 71a that can be rotated by a normal Phillips screwdriver, a protrusion 71b that protrudes from the groove is provided at the center of the groove 71a.

従って、この特殊ネジ７１を通常のプラスドライバによって回動しようとすると、プラスドライバの先端部分が突起部７１ｂに衝突し、プラスドライバを溝部７１ａと良好に係合させることができないので、通常のプラスドライバ（通常のマイナスドライバも同様）によってはこの特殊ネジ７１を回動させることはできない。 Therefore, if the special screw 71 is rotated by a normal plus driver, the tip of the plus driver collides with the protrusion 71b, and the plus driver cannot be engaged well with the groove 71a. The special screw 71 cannot be rotated depending on the driver (same for a normal minus driver).

このため、この特殊ネジ７１を回動させるためには、図５に示すように、通常のプラスドライバの先端部分の形状に加えて、この先端部分の中央が突起部７１ｂと係合可能に陥没した孔部７３を有する特殊工具７４が用いられることになる。 Therefore, in order to rotate the special screw 71, as shown in FIG. 5, in addition to the shape of the tip portion of a normal Phillips screwdriver, the center of the tip portion is depressed so that it can be engaged with the protrusion 71b. The special tool 74 having the hole 73 formed is used.

なお、通常のプラスドライバ等の工具を用いて特殊ネジ７１が確実に回動されないようにするためには、突起部７１ｂの高さを、この溝部７１ａの深さと同じかこの溝部７１ａの深さよりも高く設定すればよい。 In order to prevent the special screw 71 from being reliably rotated using a normal tool such as a Phillips screwdriver, the height of the protrusion 71b is equal to the depth of the groove 71a or from the depth of the groove 71a. Can be set higher.

また、回路基板６１をカバー部材２０の基板固定ボス３７に固定する際には、回路基板６１とカバー部材２０との間に上下一対のコネクタカバー６２が介装される。このコネクタカバー６２は、図２に示すように、回路基板６１上に設けられた図示しないコネクタ群の各コネクタの形状に対応した穴６３が形成された枠状部材であり、回路基板６１をカバー部材２０に固定すると、コネクタ群が穴６３およびコネクタ窓２６ａを介してカバー部材２０から露出されるようになっている。 When the circuit board 61 is fixed to the board fixing boss 37 of the cover member 20, a pair of upper and lower connector covers 62 are interposed between the circuit board 61 and the cover member 20. As shown in FIG. 2, the connector cover 62 is a frame-like member in which holes 63 corresponding to the shape of each connector of a connector group (not shown) provided on the circuit board 61 are formed. When fixed to the member 20, the connector group is exposed from the cover member 20 through the hole 63 and the connector window 26a.

次に、ベース部材１０について図３（ｂ）を用いて説明する。図３（ｂ）は、ベース部材１０を示す背面図である。
ベース部材１０は上下対称かつ左右対称に構成されており、図３（ｂ）に示すように、無蓋箱状の本体１１の左右側面に上下方向に等間隔に設けられ外方に延出する複数の補強リブ１２を介して、本体１１の側面に平行に延びる平板状の側壁部材１３が設けられている。そして、隣接する補強リブ１２間の空間に、本体１１の側面から延設された支持リブ１４と側壁部材１３の内面から延設された支持リブ１６とにより筒状部材１５が支持されている。この筒状部材１５は、上記筒状部材２５と同様の形状を有し、ベース部材１０において左右対称に４個ずつ計８個設けられている。 Next, the base member 10 will be described with reference to FIG. FIG. 3B is a rear view showing the base member 10.
The base member 10 is vertically and horizontally symmetrical, and as shown in FIG. 3 (b), a plurality of base members 10 are provided on the left and right side surfaces of the lidless box-like main body 11 at equal intervals in the vertical direction and extend outward. A plate-like side wall member 13 extending in parallel with the side surface of the main body 11 is provided via the reinforcing ribs 12. The cylindrical member 15 is supported in a space between the adjacent reinforcing ribs 12 by a support rib 14 extending from the side surface of the main body 11 and a support rib 16 extending from the inner surface of the side wall member 13. The cylindrical member 15 has the same shape as the cylindrical member 25, and four base members 10 are provided in a symmetrical manner on the base member 10.

そして、さらにこれら筒状部材１５の開口部には、図２（および後述する図７）に示すように、逆止リング１７が同軸状に装着されている。この逆止リング１７は、固定部材５０の後述する逆止片を係止するためのものであり、その外径が筒状部材１５の内径に一致し、内径が筒状部材２５の小径部２５ｂの内径にほぼ一致する筒状体からなる。 Further, as shown in FIG. 2 (and FIG. 7 described later), a check ring 17 is coaxially attached to the openings of these cylindrical members 15. The check ring 17 is for locking a check piece, which will be described later, of the fixing member 50. The outer diameter of the check ring 17 matches the inner diameter of the cylindrical member 15, and the inner diameter is the small diameter portion 25 b of the cylindrical member 25. It consists of a cylindrical body that substantially coincides with the inner diameter.

そして、その一端に設けられたフランジ部１７ａが筒状部材１５の開口部に係止されるようになっている。逆止リング１７は、そのフランジ部１７ａが筒状部材１５に接着されて固定される。そして、ベース部材１０にカバー部材２０が組み付けられた際には、筒状部材２５と筒状部材１５とが同軸状に配置されるように構成されている（図７参照）。 And the flange part 17a provided in the end is latched by the opening part of the cylindrical member 15. As shown in FIG. The check ring 17 is fixed with its flange portion 17 a bonded to the tubular member 15. And when the cover member 20 is assembled | attached to the base member 10, the cylindrical member 25 and the cylindrical member 15 are comprised so that it may arrange | position coaxially (refer FIG. 7).

また、本体１１の上下の側壁部１１ａからは、カバー部材２０の４つの係合部３１にそれぞれ係合可能な４つの鈎状の係合部１８がカバー部材２０側に向かって突設されている（図２および図３（ｂ）参照）。この係合部１８は、図４（ａ）に示すように、側壁部１１ａに沿って左右に延びると共にカバー部材２０側に延出した突出部１８ａと、この突出部１８ａの左右方向の一端から内方に延びると共にカバー部材２０側に延出した突出部１８ｂの先端に、これら両突出部の端縁を二辺とする長方形状の小片部１８ｃが連設された形状を有する。 Further, from the upper and lower side wall portions 11 a of the main body 11, four hook-like engaging portions 18 that can be engaged with the four engaging portions 31 of the cover member 20 are provided so as to project toward the cover member 20 side. (See FIG. 2 and FIG. 3 (b)). As shown in FIG. 4A, the engaging portion 18 extends from the left and right along the side wall portion 11a and extends to the cover member 20 side, and from one end in the left-right direction of the protruding portion 18a. It has a shape in which a rectangular small piece portion 18c having two sides extending from the ends of the projecting portions 18b extending inward and extending toward the cover member 20 is provided.

この小片部１８ｃは、上記カバー部材２０側の開口部３２に挿通可能な大きさに形成されており、当該係合部１８がカバー部材２０側の係合部３１に沿ってスライドすると、その突出部１８ｂが係合部３１の端縁に当接して係止されるようになっている。また、本体１１の側壁部１１ａよりも内側の位置には、４つの係合部１８と対向するように、左右方向に延びる防護リブ１９がカバー部材２０側に突設されており、図４（ａ）のようにカバー部材２０がベース部材１０に組み付けられた際には、カバー部材２０の側壁部２７が、係合部１８と防護リブ１９とにより挟持されつつ支持されるようになっている。 The small piece portion 18c is formed in a size that can be inserted into the opening portion 32 on the cover member 20 side, and protrudes when the engagement portion 18 slides along the engagement portion 31 on the cover member 20 side. The part 18b is brought into contact with and locked to the end edge of the engaging part 31. Further, a protective rib 19 extending in the left-right direction is provided on the cover member 20 side so as to face the four engaging portions 18 at a position inside the side wall portion 11a of the main body 11, and FIG. When the cover member 20 is assembled to the base member 10 as in a), the side wall portion 27 of the cover member 20 is supported while being sandwiched between the engaging portion 18 and the protective rib 19. .

そしてさらに、このガイド部材２９と側壁部２７から延設された係合部３１とにより、カバー部材２０の係合部１８を挟持する態様で、カバー部材２０とベース部材１０とが固定されている。このため、第三者が外方から側壁部２７を内方に押し込んでカバー部材２０をベース部材１０から脱離させる等の不正行為が有効に防止される。 Further, the cover member 20 and the base member 10 are fixed in such a manner that the engaging portion 18 of the cover member 20 is sandwiched between the guide member 29 and the engaging portion 31 extending from the side wall portion 27. . For this reason, an illegal act such as a third party pushing the side wall portion 27 inward from the outside to remove the cover member 20 from the base member 10 is effectively prevented.

次に、基板ケース１におけるカバー部材２０とベース部材１０との組み付けについて説明する。カバー部材２０とベース部材１０との組み付けの際には、上述のように回路基板６１が組み付けられたカバー部材２０を、ベース部材１０に組み付ける。この際、カバー部材２０の開口部３２とベース部材１０の小片部１８ｃとを突き合わせて、その係合部１８を開口部３２に挿入する。そして、カバー部材２０の係合部３１とベース部材１０の係合部１８とを係合させる方向に、カバー部材２０をベース部材１０に対してスライドさせる。そして、係合部３１の先端がベース部材１０の係合部１８に係止されることにより重合状態となる。 Next, assembly of the cover member 20 and the base member 10 in the substrate case 1 will be described. When the cover member 20 and the base member 10 are assembled, the cover member 20 on which the circuit board 61 is assembled as described above is assembled to the base member 10. At this time, the opening portion 32 of the cover member 20 and the small piece portion 18 c of the base member 10 are brought into contact with each other, and the engaging portion 18 is inserted into the opening portion 32. Then, the cover member 20 is slid with respect to the base member 10 in a direction in which the engaging portion 31 of the cover member 20 and the engaging portion 18 of the base member 10 are engaged. Then, the leading end of the engaging portion 31 is engaged with the engaging portion 18 of the base member 10 to be in a superimposed state.

このようにすることによって、カバー部材２０とベース部材１０とは組み付けられる。ただし、カバー部材２０に配置された固定部材５０の全てが後述する待機空間に保持されている状態においては、カバー部材２０はベース部材１０に対して完全には固定されていない。よって、この状態においては、カバー部材２０とベース部材１０とは、そのスライド方向に動作されることにより分離可能である。 By doing so, the cover member 20 and the base member 10 are assembled. However, the cover member 20 is not completely fixed to the base member 10 in a state where all of the fixing members 50 arranged on the cover member 20 are held in a standby space described later. Therefore, in this state, the cover member 20 and the base member 10 can be separated by being operated in the sliding direction.

次に、カバー部材２０とベース部材１０とを完全に固定する際に使用される固定部材５０について図６を用いて説明する。図６は固定部材５０を表す説明図である。
固定部材５０は、図６に示すように、下方にやや縮径した円柱状の本体５１の上端部にフランジ状の係止部５２が形成され、その中央から下端にかけて軸線に沿った所定幅のスリット５３が形成されている。このため、固定部材５０の下部はスリット５３の幅方向に所定量弾性変形できるようになっている。 Next, the fixing member 50 used when completely fixing the cover member 20 and the base member 10 will be described with reference to FIG. FIG. 6 is an explanatory view showing the fixing member 50.
As shown in FIG. 6, the fixing member 50 has a flange-like locking portion 52 formed at the upper end portion of a cylindrical main body 51 that is slightly reduced in diameter, and has a predetermined width along the axis from the center to the lower end. A slit 53 is formed. Therefore, the lower part of the fixing member 50 can be elastically deformed by a predetermined amount in the width direction of the slit 53.

また、本体５１の下端には、外径方向に突出した逆止片５４が設けられている。この逆止片５４は、固定部材５０の下端側から上方に向かってその断面が大きくなるテーパ状に形成され、その下端部が挿入部５４ａを、上端部が係止部５４ｂをそれぞれ形成している。 Further, a check piece 54 protruding in the outer diameter direction is provided at the lower end of the main body 51. The check piece 54 is formed in a tapered shape whose cross section increases from the lower end side of the fixing member 50 upward, and the lower end portion forms an insertion portion 54a and the upper end portion forms a locking portion 54b. Yes.

従って、固定部材５０が所定の孔に挿入される際には、挿入部５４ａがテーパ状になっていることから孔入口にスムーズに導入され、さらに固定部材５０がその下部で撓みながら孔内にスムーズに挿入される。そして、逆止片５４が孔を貫通すると、固定部材５０の下端部が弾性復帰して係止部５４ｂが係止されるため、固定部材５０を挿入方向とは逆方向に引き抜くことは不可能となる。 Therefore, when the fixing member 50 is inserted into the predetermined hole, the insertion portion 54a is tapered, so that the fixing member 50 is smoothly introduced into the hole inlet. Inserts smoothly. When the check piece 54 penetrates the hole, the lower end portion of the fixing member 50 is elastically restored and the locking portion 54b is locked. Therefore, the fixing member 50 cannot be pulled out in the direction opposite to the insertion direction. It becomes.

また、固定部材５０の上端部には、ワッシャ５５を介してワンウェイねじ５６が螺入されている。このワッシャ５５には、その外径が係止部５２の上端面の外径と同一のものが使用されているため、固定部材５０の係止部５２の表面は、金属部材により覆われるようになっている。なお、このワンウェイねじ５６は、周知のように、締結方向にのみ回動可能に構成されたねじであり、一旦係止部５２に螺入されると、工具を用いてこれをリバースさせることは極めて困難となる。 A one-way screw 56 is screwed into the upper end portion of the fixing member 50 via a washer 55. Since the outer diameter of the washer 55 is the same as the outer diameter of the upper end surface of the locking portion 52, the surface of the locking portion 52 of the fixing member 50 is covered with a metal member. It has become. As is well known, the one-way screw 56 is a screw configured to be rotatable only in the fastening direction, and once screwed into the locking portion 52, it is possible to reverse this using a tool. It becomes extremely difficult.

次に、基板ケース１の封止方法について図７を用いて説明する。図７は図１のＢ−Ｂ断面であって基板ケース１の封止構造を表す説明図である。
図７に示すように、カバー部材２０における被覆部材３５の上壁部３５ａにおいて４つの筒状部材２５に対応する位置には、これら筒状部材２５と同様の形状を有する４つの筒状部３５ｂが重合方向に延設され、これら筒状部３５ｂの孔と対応する筒状部材２５の孔とが連通するように構成されている。そして、固定部材５０は、図７において最も左側の固定部材５０のように、その逆止片５４が筒状部材２５の段差部２５ａに支持され、係止部５２が筒状部３５ｂの内壁に支持される態様で、被覆部材３５と筒状部材２５との間に形成される待機空間に一時的に保持される。 Next, a method for sealing the substrate case 1 will be described with reference to FIG. FIG. 7 is an explanatory diagram showing a sealing structure of the substrate case 1 taken along the line BB of FIG.
As shown in FIG. 7, four cylindrical portions 35 b having the same shape as those of the cylindrical members 25 are located at positions corresponding to the four cylindrical members 25 in the upper wall portion 35 a of the covering member 35 in the cover member 20. Are extended in the superposition direction, and the holes of the cylindrical portions 35b and the corresponding holes of the cylindrical member 25 are configured to communicate with each other. Then, as in the leftmost fixing member 50 in FIG. 7, the fixing member 50 has its check piece 54 supported by the step portion 25a of the cylindrical member 25, and the locking portion 52 on the inner wall of the cylindrical portion 35b. In a supported manner, the holding space is temporarily held in a standby space formed between the covering member 35 and the tubular member 25.

そして、基板ケース１の封止の際には、カバー部材２０とベース部材１０とが組み付けられた重合状態において、所定の棒状部材をカバー部材２０の小孔３５ｃに挿通し、上述した待機空間にて待機状態にある固定部材５０のいずれかを押圧して、これを筒状部材２５および筒状部材１５により形成される連通孔５８内に挿入する。すると、図７において左から２番目の固定部材５０のように、固定部材５０が筒状部材２５の小径部２５ｂと逆止リング１７内部により形成される連通孔５８内に挿通される。 When the substrate case 1 is sealed, in a superposed state in which the cover member 20 and the base member 10 are assembled, a predetermined rod-shaped member is inserted into the small hole 35c of the cover member 20, and the above-described standby space is inserted. Then, one of the fixed members 50 in the standby state is pressed and inserted into the communication hole 58 formed by the cylindrical member 25 and the cylindrical member 15. Then, like the second fixing member 50 from the left in FIG. 7, the fixing member 50 is inserted into the communication hole 58 formed by the small diameter portion 25 b of the tubular member 25 and the inside of the check ring 17.

このとき、固定部材５０の逆止片５４が逆止リング１７の端面に、係止部５２が筒状部材２５の段差部２５ａにそれぞれ係止されることにより、固定部材５０がベース部材１０とカバー部材２０とを挟持する態様でこれらを互いに固定して基板ケース１を封止する。このとき、固定部材５０は連通孔５８に対して遊嵌されているため、自軸周りに回動可能となっている。 At this time, the check piece 54 of the fixing member 50 is locked to the end surface of the check ring 17, and the locking portion 52 is locked to the step portion 25 a of the cylindrical member 25. These are fixed to each other so as to sandwich the cover member 20, and the substrate case 1 is sealed. At this time, since the fixing member 50 is loosely fitted into the communication hole 58, the fixing member 50 can rotate around its own axis.

なお、この封止作業においては、左右に４対（計８個）配設された固定部材５０のうち、左右対称に配置された一対（２個）が使用されるため、本実施例の場合、遊技機の出荷時を含めて計４回の封止が可能となっている。また、封止状態を解除する際には、このとき用いられた固定部材５０を保持する筒状部材２５の支持リブ２４および筒状部材１５の支持リブ１４、１６をニッパ等の工具により切断して取り除き、上述した操作を逆に行なえば、カバー部材２０をベース部材１０から離脱させることができる。 In this sealing operation, since a pair (two) of the fixing members 50 arranged in the left and right (a total of eight) are used symmetrically, a pair (two) of the fixing members 50 is used. A total of four times of sealing is possible including when the gaming machine is shipped. When releasing the sealing state, the support rib 24 of the cylindrical member 25 and the support ribs 14 and 16 of the cylindrical member 15 that hold the fixing member 50 used at this time are cut with a tool such as a nipper. The cover member 20 can be detached from the base member 10 if the above-described operation is reversed.

以上のように詳述した基板ケース１は、遊技機に固定されるベース部材１０と、このベース部材１０に組み付けられ、このベース部材１０との間に所定の収納空間を形成するカバー部材２０と、ベース部材１０とカバー部材２０とを組み付けた状態で固定する固定部材５０と、を備え、この遊技機を制御する電子部品が実装された回路基板６１を収納空間に封止する遊技機の基板ケース１であって、回路基板６１における電子部品が実装された実装面側に位置するカバー部材２０に対して、この回路基板６１を固定する特殊ネジ７１と、収納空間において回路基板６１における実装面の裏面側の全面を覆って配置される内部カバー６０と、回路基板６１が固定されたカバー部材２０に対して、内部カバー６０を固定する通常ネジ７２と、を備えている。 The board case 1 described in detail above includes a base member 10 fixed to a gaming machine, and a cover member 20 that is assembled to the base member 10 and forms a predetermined storage space between the base member 10 and the base member 10. And a fixing member 50 for fixing the base member 10 and the cover member 20 in an assembled state, and a circuit board 61 on which an electronic component for controlling the gaming machine is mounted is sealed in a storage space. A special screw 71 for fixing the circuit board 61 to the cover member 20 located on the mounting surface side of the circuit board 61 on which the electronic components are mounted, and the mounting surface of the circuit board 61 in the storage space. An inner cover 60 disposed so as to cover the entire back surface side of the cover, and a normal screw 72 for fixing the inner cover 60 to the cover member 20 to which the circuit board 61 is fixed. To have.

即ち、この基板ケース１においては、基板ケース１を不正に開封しようとする第三者が回路基板６１に触れるためには、固定部材５０、特殊ネジ７１、および通常ネジ７２の全ての固定部材を取り外さなければならない。 That is, in this board case 1, all the fixing members of the fixing member 50, the special screw 71, and the normal screw 72 are used in order for a third party who attempts to open the board case 1 illegally to touch the circuit board 61. Must be removed.

従って、特殊ネジ７１または通常ネジ７２のうちの一方のみで回路基板６１および内部カバー６０を固定した従来の基板ケースと比較して、第三者が回路基板６１を触れるまでには時間が掛かるため、基板ケース１を不正に開封しようとする第三者の気力を減退させることができる。よって、回路基板６１が電子部品の交換や改造等の不正行為を受け難くすることができる。 Therefore, compared to the conventional board case in which the circuit board 61 and the inner cover 60 are fixed with only one of the special screw 71 and the normal screw 72, it takes time until the third party touches the circuit board 61. The power of a third party who attempts to open the substrate case 1 illegally can be reduced. Therefore, the circuit board 61 can be made less susceptible to fraudulent acts such as replacement or modification of electronic components.

また、基板ケース１において、特殊ネジ７１および通常ネジ７２には、所定形状の溝部が形成されているとともに、溝部と係合する特定の工具を用いて特殊ネジ７１および通常ネジ７２が操作されることにより特殊ネジ７１および通常ネジ７２がカバー部材２０から取り外されるよう構成されており、特殊ネジ７１に形成された溝部７１ａの形状と、通常ネジ７２に形成された溝部の形状とは、異なる形状に設定されている。 In the substrate case 1, the special screw 71 and the normal screw 72 are formed with a groove having a predetermined shape, and the special screw 71 and the normal screw 72 are operated using a specific tool that engages with the groove. Thus, the special screw 71 and the normal screw 72 are configured to be removed from the cover member 20, and the shape of the groove portion 71 a formed in the special screw 71 is different from the shape of the groove portion formed in the normal screw 72. Is set to

従って、このような基板ケース１によれば、特殊ネジ７１と通常ネジ７２とを同一の工具で取り外すことができないので、各固定部材に対応した複数の工具を所持していない第三者には回路基板６１の電子部品に触れさせないようにすることができる。よって、回路基板６１が改造等の不正行為をより受け難くすることができる。 Therefore, according to such a substrate case 1, the special screw 71 and the normal screw 72 cannot be removed with the same tool, so that a third party who does not have a plurality of tools corresponding to each fixing member is used. The electronic components of the circuit board 61 can be prevented from touching. Therefore, the circuit board 61 can be made more difficult to receive illegal acts such as remodeling.

［実施例２］
次に、別形態の基板ケース２について説明する。本実施例（実施例２）では、実施例１の基板ケース１と異なる箇所のみを詳述し、実施例１の基板ケース１と同様の箇所については、同一の符号を付して説明を省略する。 [Example 2]
Next, another form of the substrate case 2 will be described. In the present embodiment (embodiment 2), only portions different from the substrate case 1 of the embodiment 1 will be described in detail, and the same portions as those of the substrate case 1 of the embodiment 1 will be denoted by the same reference numerals and description thereof will be omitted. To do.

図８は、本実施例の基板ケース２におけるベース部材１０とカバー部材２０との組み付け状態を示す説明図である。
実施例１の基板ケース１におけるカバー部材２０において、カバー固定ボス３８は、基板固定ボス３７よりもカバー部材２０の外周側に配置されていたが、本実施例のカバー部材２０において、カバー固定ボス３８は、基板固定ボス３７の内側に配置されている。このため、本実施例の回路基板６１には、カバー固定ボス３８を挿通するための挿通孔６１ａが形成されている。つまり、内部カバー６０は、回路基板６１とともに特殊ネジ７１も覆う構成にされている。 FIG. 8 is an explanatory diagram showing an assembled state of the base member 10 and the cover member 20 in the substrate case 2 of the present embodiment.
In the cover member 20 in the substrate case 1 of the first embodiment, the cover fixing boss 38 is disposed on the outer peripheral side of the cover member 20 with respect to the substrate fixing boss 37. However, in the cover member 20 of the present embodiment, the cover fixing boss 38 is disposed. 38 is disposed inside the substrate fixing boss 37. For this reason, the circuit board 61 of the present embodiment is formed with an insertion hole 61 a for inserting the cover fixing boss 38. That is, the inner cover 60 is configured to cover the special screw 71 together with the circuit board 61.

また、本実施例の内部カバー６０においては、それぞれの基板固定ボス３７の近傍においてベース部材１０側（図８では下側）に突出した突出部６０ａが形成されており、この突出部６０ａが形成されたことにより生じた空間（回路基板６１と内部カバー６０との間の間隙）に不透明な樹脂等の部材からなる隠蔽部材６０ｂを備えている。 Further, in the inner cover 60 of the present embodiment, a protruding portion 60a protruding to the base member 10 side (lower side in FIG. 8) is formed in the vicinity of each substrate fixing boss 37, and this protruding portion 60a is formed. A concealing member 60b made of a member such as an opaque resin is provided in a space (gap between the circuit board 61 and the inner cover 60) generated as a result.

ここで、この隠蔽部材６０ｂは、特殊ネジ７１のヘッドを覆うように配置されており、内部カバー６０が取り付けられた状態では、外部から特殊ネジ７１のヘッドの形状を視認することができない。このため、特殊ネジ７１のヘッドの形状を知らない第三者には、特殊ネジ７１を取り外すために必要となる工具を事前に準備することができない。 Here, the concealing member 60b is arranged so as to cover the head of the special screw 71, and when the inner cover 60 is attached, the shape of the head of the special screw 71 cannot be visually recognized from the outside. For this reason, a third party who does not know the shape of the head of the special screw 71 cannot prepare in advance a tool necessary for removing the special screw 71.

また、特殊ネジ７１の存在を不透明な部材である隠蔽部材６０ｂによって隠蔽することにより、このカバー部材２０を見る角度によっては、このカバー部材２０を一見しただけでは、回路基板６１および内部カバー６０が通常ネジ７２のみによって共締めされているように見える。このため、第三者が当該基板ケース２を容易に開封できるものと思い開封作業を開始したとしても、内部カバー６０を取り外した後でさらに特殊な工具を必要とする特殊ネジ７１の存在に気付くことになる。 Further, by concealing the presence of the special screw 71 by the concealing member 60b, which is an opaque member, depending on the angle at which the cover member 20 is viewed, the circuit board 61 and the inner cover 60 can be removed only by looking at the cover member 20. It seems that it is usually fastened together with only the screw 72. For this reason, even if a third party thinks that the board case 2 can be easily opened and starts the opening operation, he notices the presence of the special screw 71 that requires a special tool after the inner cover 60 is removed. It will be.

つまり、第三者は、容易に開封できるものと思っていたにもかかわらず、開封作業を開始してから開封に時間が掛かることに気付くので、第三者は精神的な打撃を受け、開封作業に対する気力がそがれることになる。よって、このような基板ケース２においても、基板ケース２が開封され難くすることができる。 In other words, even though the third party thought that it could be opened easily, it noticed that it would take some time to open after opening, so the third party suffered a mental blow and opened it. The energy for work will be distracted. Therefore, even in such a substrate case 2, the substrate case 2 can be made difficult to open.

［実施例３］
次に、さらに別形態の基板ケース３について説明する。本実施例（実施例３）では、実施例１，２の基板ケース１，２と異なる箇所のみを詳述し、実施例１，２の基板ケース１，２と同様の箇所については、同一の符号を付して説明を省略する。 [Example 3]
Next, another form of the substrate case 3 will be described. In the present embodiment (third embodiment), only portions different from the substrate cases 1 and 2 of the first and second embodiments will be described in detail, and the same portions as those of the substrate cases 1 and 2 of the first and second embodiments are the same. The reference numerals are attached and the description is omitted.

図９は、本実施例の基板ケース３におけるベース部材１０とカバー部材２０との組み付け状態を示す説明図である。
実施例１，２のカバー部材２０においては、カバー固定ボス３８を備えていたが、本実施例のカバー部材２０においては、カバー固定ボス３８を備えていない。このため、本実施例の基板ケース３においては、内部カバー６０が収納空間において回路基板６１における実装面の裏面側の全面、および特殊ネジ７１を覆って配置され、カバー固定ボス３８に螺合される通常ネジ７２に換えて、図９に示すように、内部カバー６０と回路基板６１とを結合した状態で封止する封止部材７５（封止手段）を備えている。 FIG. 9 is an explanatory diagram showing an assembled state of the base member 10 and the cover member 20 in the substrate case 3 of the present embodiment.
In the cover members 20 of the first and second embodiments, the cover fixing boss 38 is provided. However, the cover member 20 of the present embodiment does not include the cover fixing boss 38. For this reason, in the substrate case 3 of the present embodiment, the inner cover 60 is disposed so as to cover the entire back surface side of the mounting surface of the circuit board 61 and the special screw 71 in the storage space, and is screwed to the cover fixing boss 38. In place of the normal screw 72, a sealing member 75 (sealing means) for sealing the inner cover 60 and the circuit board 61 in a coupled state is provided as shown in FIG.

この封止部材７５は、前述の固定部材５０と同様に、スリット７６、逆止片７７を備え、この逆止片７７には挿入部７７ａ、係止部７７ｂが形成されている。
従って、封止部材７５が所定の孔に挿入される際には、テーパ状に形成された挿入部７７ａが孔入口にスムーズに導入され、さらに封止部材７５がその下部で撓みながら孔内にスムーズに挿入される。そして、逆止片７７が孔を貫通すると、封止部材７５の下端部が弾性復帰して係止部７７ｂが係止されるため、封止部材７５を挿入方向とは逆方向に引き抜くことは不可能となる。この構成によって内部カバー６０と回路基板６１との結合関係が維持される。 The sealing member 75 includes a slit 76 and a check piece 77 as in the case of the fixing member 50 described above, and the check piece 77 is formed with an insertion portion 77a and a locking portion 77b.
Therefore, when the sealing member 75 is inserted into the predetermined hole, the insertion portion 77a formed in a tapered shape is smoothly introduced into the hole inlet, and further, the sealing member 75 is bent in the lower portion thereof and is inserted into the hole. Inserts smoothly. When the check piece 77 penetrates the hole, the lower end portion of the sealing member 75 is elastically restored and the locking portion 77b is locked, so that the sealing member 75 cannot be pulled out in the direction opposite to the insertion direction. It becomes impossible. With this configuration, the coupling relationship between the inner cover 60 and the circuit board 61 is maintained.

なお、回路基板６１は、カバー部材２０に対して固定されているため、内部カバー６０は、封止部材７５によってカバー部材２０に対して固定されているとも言える。
このような基板ケース３によれば、封止部材７５を破壊しなければ電子部品に触れることができないので、封止部材７５の破壊に手間が掛かる分だけ電子部品が第三者に触れられ難くすることができる。また、仮に電子部品が触れられてしまった場合には、封止部材７５は破壊された状態になるので、この基板ケース３の管理者は電子部品が第三者によって触れられたことを容易に識別することができる
［その他の実施形態］
本発明の実施の形態は、上記の実施例に何ら限定されることはなく、本発明の技術的範囲に属する限り種々の形態を採りうる。 Since the circuit board 61 is fixed to the cover member 20, it can be said that the inner cover 60 is fixed to the cover member 20 by the sealing member 75.
According to such a substrate case 3, since the electronic component cannot be touched unless the sealing member 75 is destroyed, the electronic component is hardly touched by a third party as much as it takes time to destroy the sealing member 75. can do. Further, if the electronic component has been touched, the sealing member 75 is in a broken state, so that the administrator of the board case 3 can easily confirm that the electronic component has been touched by a third party.
