Description

本発明は、内部に基板が保持されて遊技盤の裏面側に取り付けられる基板ケースに関する。 The present invention relates to a substrate case in which a substrate is held and attached to the back side of a game board.

パチンコ機やスロットマシン等の遊技機では、この遊技機の作動を制御する制御基板が設けられている。例えば、パチンコ遊技機では、外枠に対して開閉可能に組み付けられた前枠裏側の収容枠に遊技盤等が装備され、この遊技盤に制御基板が取り付けられている。スロットマシンにおいても同様に、開閉カバーの裏面に制御基板が取り付けられている。 In gaming machines such as pachinko machines and slot machines, a control board for controlling the operation of the gaming machine is provided. For example, in a pachinko gaming machine, a game board or the like is mounted on a storage frame on the back side of a front frame that is assembled to be openable and closable with respect to an outer frame, and a control board is attached to the game board. Similarly, in the slot machine, a control board is attached to the back surface of the opening / closing cover.

これらの制御基板は、賞球若しくはメダルの払出制御、電動役物の開閉制御、リールの回転制御、図柄組み合わせの発生確率制御等、パチンコ機若しくはスロットマシンの作動を制御する基板であり、遊技機の制御ソフトウェアが記録されたＲＯＭが搭載され、この遊技機の作動を制御する中枢制御装置としての役割を有している。このため、制御基板は、偽造ＲＯＭへの差し替え等の不正改造を防止するために、基板ケース内に収容されるとともに、この基板ケースはケースを開いたときにその痕跡が残るような不正開放（若しくは、不正着脱）の防止手段が設けられて構成されている（例えば、特許文献１参照）。 These control boards are boards that control the operation of pachinko machines or slot machines, such as prize ball or medal payout control, opening / closing control of electric accessories, reel rotation control, symbol combination occurrence probability control, etc. A ROM in which the control software is recorded is mounted and has a role as a central control device for controlling the operation of the gaming machine. For this reason, the control board is accommodated in a board case to prevent unauthorized modification such as replacement with a counterfeit ROM, and the board case is illegally opened so that its trace remains when the case is opened ( Alternatively, a means for preventing unauthorized attachment / detachment is provided (see, for example, Patent Document 1).

しかしながら、不正開放防止機構が設けられていたとしても、例えば、基板ケースが本体部材と蓋部材とから構成されている場合、この本体部材と蓋部材との結合部にクリアランス（隙間）があると、そこから、ドライバ等を差込んで、この基板ケースを不正に開放することや、内部に収容された基板を不正に操作することができるという課題がある。 However, even if the unauthorized opening prevention mechanism is provided, for example, when the substrate case is composed of a main body member and a lid member, there is a clearance (gap) at the joint between the main body member and the lid member. From there, there is a problem that a driver or the like is inserted to open the substrate case illegally or to illegally operate the substrate accommodated therein.

本発明はこのような課題に鑑みてなされたものであり、主基板ケースの結合部のクリアランスを小さくするようにした基板ケースを提供することを目的とする。 The present invention has been made in view of such problems, and an object of the present invention is to provide a substrate case in which the clearance of the coupling portion of the main substrate case is reduced.

前記課題を解決するために、本発明に係る基板ケース（例えば、実施形態における主基板ケース１００）は、開口部の側部（例えば、実施形態における第２壁部５３ｂ）に断面Ｌ字状の溝である蓋部材取付溝が形成された本体部材（例えば、実施形態におけるケース本体部材５０）と、開口部の側部（例えば、実施形態における側壁部６９）から外方に突出した突起である係止突起部が形成された蓋部材（例えば、実施形態におけるケース蓋部材６０）とから構成され、本体部材の開口部と蓋部材の開口部とを合わせるようにして係止突起部を蓋部材取付溝に挿入し、本体部材に対して蓋部材をスライド移動させて係止突起部と蓋部材取付溝とを係合させて、内部に基板（例えば、実施形態における主制御基板３１）を収容する。この基板ケースにおいて、本体部材が、蓋部材取付溝と対向する位置に、この蓋部材取付溝が形成された側部と略平行に延びる板状の蓋部材押圧壁を有し、蓋部材が、側部から内方に突出した突起であって係止突起部に対してスライド移動方向と反対方向にずれて形成された押圧突起部を有して構成される。そして、係止突起部を蓋部材取付溝に挿入するときは、蓋部材の側部を本体部材の側部と蓋部材押圧壁との間に挿入し、本体部材に対して蓋部材をスライド移動するときに、蓋部材押圧壁により押圧突起部が外方に押されて、本体部材の側部と蓋部材の側部とが当接するように構成される。 In order to solve the above problems, a substrate case according to the present invention (for example, the main substrate case 100 in the embodiment) has an L-shaped cross section on a side portion of the opening (for example, the second wall portion 53b in the embodiment). A main body member (for example, the case main body member 50 in the embodiment) in which a lid member mounting groove, which is a groove, is formed, and a protrusion protruding outward from a side portion of the opening (for example, the side wall portion 69 in the embodiment). And a lid member (for example, the case lid member 60 in the embodiment) in which the latching projection is formed, and the latching projection is configured as a lid member so that the opening of the main body member and the opening of the lid member are aligned. The board is inserted into the mounting groove, and the lid member is slid with respect to the main body member to engage the locking projection and the lid member mounting groove to accommodate the board (for example, the main control board 31 in the embodiment) inside. To do. In this substrate case, the main body member has a plate-like lid member pressing wall extending substantially parallel to the side portion where the lid member attachment groove is formed at a position facing the lid member attachment groove, and the lid member is A protrusion protruding inward from the side and having a pressing protrusion formed in a direction opposite to the sliding movement direction with respect to the locking protrusion . When inserting the locking projection into the lid member mounting groove, insert the side part of the lid member between the side part of the main body member and the lid member pressing wall, and slide the lid member relative to the main body member. In this case, the pressing protrusion is pushed outward by the lid member pressing wall, and the side portion of the main body member and the side portion of the lid member are in contact with each other.

このような本発明に係る基板ケースにおいて、押圧突起部のスライド移動する方向の面（例えば、実施形態における面取り部６１ａ）がテーパ状に形成されていることが好ましい。 In such a substrate case according to the present invention, it is preferable that the surface of the pressing protrusion in the sliding direction (for example, the chamfered portion 61a in the embodiment) is formed in a tapered shape.

また、本体部材の蓋部材取付溝が形成された側部の外側に、補強用のリブが形成されていることが好ましい。 Further, it is preferable that a reinforcing rib is formed outside the side portion of the main body member where the lid member mounting groove is formed.

本発明に係る主基板ケースを以上のように構成すると、係止突起部を蓋部材取付溝に挿入するときは、本体部材の側部と蓋部材押圧壁との間は、蓋部材の側部の厚さに比べて十分に広いので、本体部材の開口部と蓋部材の開口部をスムーズに合わせることができる。そして、本体部材に対して蓋部材をスライド移動すると、蓋部材押圧壁により押圧突起部が外方に押されて、本体部材の側部と蓋部材の側部とが当接するため、本体部材と蓋部材との結合部のクリアランスがほとんどなくなるため、この結合部から内部にドライバ等が挿入されるのを防止することができる。また、蓋部材の側部は、蓋部材押圧壁および押圧突起部により本体部材の側部に押しつけられているため、この蓋部材の側部を内側に押し込んで、係止突起部と蓋部材取付溝との係合を外す操作を防止することができる。 When the main board case according to the present invention is configured as described above, when the locking projection is inserted into the lid member mounting groove, the side portion of the lid member is between the side portion of the main body member and the lid member pressing wall. Therefore, the opening of the main body member and the opening of the lid member can be smoothly aligned. Then, when the lid member is slid relative to the main body member, the pressing protrusion is pushed outward by the lid member pressing wall, and the side portion of the main body member and the side portion of the lid member come into contact with each other. Since there is almost no clearance at the coupling portion with the lid member, it is possible to prevent a driver or the like from being inserted into the inside from the coupling portion. Moreover, since the side part of the lid member is pressed against the side part of the main body member by the lid member pressing wall and the pressing projection part, the side part of the lid member is pushed inward, and the locking projection part and the lid member are attached. The operation of releasing the engagement with the groove can be prevented.

このとき、押圧突起部のスライド移動する方向の面をテーパ状に形成することにより、押圧突起部は、蓋部材押圧壁に対してこの面で当接するため、テーパ状の面に沿って押圧突起部が外方に押し出されるので、本体部材に対して蓋部材をスムーズにスライド移動させることができる。 At this time, the surface of the pressing protrusion in the sliding direction is formed in a taper shape so that the pressing protrusion comes into contact with this surface against the lid member pressing wall, so that the pressing protrusion along the tapered surface. Since the portion is pushed outward, the lid member can be smoothly slid relative to the main body member.

また、本体部材の蓋部材取付溝が形成された側部の外側に補強用のリブを形成することにより、この本体部材の側部を外方に押し広げることができず、係止突起部と蓋部材取付溝との係合を外す操作を防止できる。 Further, by forming a reinforcing rib on the outside of the side portion of the main body member where the lid member mounting groove is formed, the side portion of the main body member cannot be spread outward, and the locking projection The operation of releasing the engagement with the lid member mounting groove can be prevented.

Further, a lid member pressing wall 52 is formed to extend rearward from the bottom 51 in a plate shape so as to face each of the lid member mounting grooves 54 in parallel with the inner wall surface of the first wall portion 53a. The lateral width of the lid member pressing wall 52 is formed to be approximately the same as the lateral width of the lid member mounting groove 54, and when viewed from above or below in the state of FIG. 52 and the lid member mounting groove 54 are arranged so as to overlap.

ケース蓋部材６０は、ケース本体部材５０の開口を覆う矩形箱状の形状を有しており、ＡＢＳ樹脂やポリカーボネート（ＰＣ）等の透明な樹脂材料を用いて射出成形等の成形手段により一体的に成形される。図８に示すように、このケース蓋部材６０の上下方向縁部から前方に延びる側壁部６９には、外方（図４においては上下方向）に突出する係止突起部６２が複数形成されている。この係止突起部６２は、上述の蓋部材取付溝５４と同じ数だけ形成されており、その配置間隔も蓋部材取付溝５４と対応している。また、この側壁部６９の内側面には、各々の係止突起部６２と対応して、内方に突出する押圧突起部６１が形成されている。この押圧突起部６１は、係止突起部６２に対して、ケース本体部材５０にケース蓋部材６０を取り付けるときにスライド移動させる方向と反対方向にずれて形成されている。そして、図９に示すように、この押圧突起部６１のスライド方向側の面はテーパ状に形成された面取り部６１ａを有している。 The case lid member 60 has a rectangular box shape covering the opening of the case body member 50, and is integrally formed by a molding means such as injection molding using a transparent resin material such as ABS resin or polycarbonate (PC). To be molded. As shown in FIG. 8, a plurality of locking projections 62 projecting outward (upward and downward in FIG. 4) are formed on the side wall 69 extending forward from the vertical edge of the case lid member 60. Yes. The locking projections 62 are formed in the same number as the lid member mounting groove 54 described above, and the arrangement interval thereof also corresponds to the lid member mounting groove 54. Further, on the inner side surface of the side wall portion 69, a pressing projection portion 61 projecting inward is formed corresponding to each locking projection portion 62. The pressing protrusion 61 is formed so as to be shifted with respect to the locking protrusion 62 in a direction opposite to the direction of sliding when the case lid member 60 is attached to the case body member 50. As shown in FIG. 9, the surface on the slide direction side of the pressing protrusion 61 has a chamfered portion 61a formed in a tapered shape.

そのため、図１０（ｃ）に示すように、ケース本体部材５０に対してケース蓋部材６０を取り付けるときは、図３の状態で、後方から、蓋部材取付溝５４の挿入溝部５４ａに係止突起部６２を挿入し、その後、ケース蓋部材６０を左右方向（この実施例においては左方向）にスライド移動させて係止突起部６２を係止溝部５４ｂに挿入させることで、係止突起部６２と蓋部材取付溝５４とを嵌合させる。なお、挿入溝部５４ａに係止突起部６２を挿入すると、ケース蓋部材６０の側壁部６９の前面は、第１壁部５３ａの後端面（側壁部５３の段部）に支持される。 Therefore, as shown in FIG. 10 (c), when attaching the case lid member 60 to the case body member 50, in the state of FIG. 3, from the rear, the locking projection is inserted into the insertion groove portion 54a of the lid member attachment groove 54. After the portion 62 is inserted, the case lid member 60 is slid in the left-right direction (leftward in this embodiment) to insert the locking projection 62 into the locking groove 54b, whereby the locking projection 62 And the lid member mounting groove 54 are fitted. When the locking projection 62 is inserted into the insertion groove 54a, the front surface of the side wall 69 of the case lid member 60 is supported by the rear end surface of the first wall 53a (the step of the side wall 53).

このとき、図１１（ａ）に示すように、係止突起部６２を挿入溝部５４ａに挿入した状態では、押圧突起部６１は、蓋部材押圧壁５２の右方に位置するが、この状態から、ケース蓋部材６０をケース本体部材５０に対して左方にスライド移動させると、係止突起部６２が係止溝部５４ｂに挿入されるにしたがって、まず、押圧突起部６１の面取り部６１ａが蓋部材押圧壁５２の右端部に当接し、ケース蓋部材６０のスライド移動に伴って、この面取り部６１ａに沿って側壁部６９が外方に押し出される。そして、図１１（ｂ）に示すように、係止突起部６２が係止溝部５４ｂに完全に挿入された状態では、側壁部６９の外側面と第２壁部５３ｂの内側面とが密接し、押圧突起部６１は第２壁部５３ｂと蓋部材押圧壁５２とに挟持される。そのため、係止突起部６２を挿入溝部５４ａに挿入するときは、第２壁部５３ｂと壁部材押圧壁５２との間隔は、側壁部６９の厚さに比べて十分に広いので、ケース本体部材５０の開口部とケース蓋部材６０の開口部とをスムーズに合わせることができるが、ケース蓋部材６０をケース本体部材５０に対してスライド移動させて係止突起部６２と蓋部材取付溝５４とを係合させたときは、側壁部６９と第２壁部５３ｂとは密接してこれらの間のクリアランスを小さくする（ほとんどなくす）ことができる。 At this time, as shown in FIG. 11A, in a state where the locking projection 62 is inserted into the insertion groove 54a, the pressing projection 61 is located on the right side of the lid member pressing wall 52. When the case lid member 60 is slid to the left with respect to the case body member 50, the chamfered portion 61a of the pressing projection 61 is first covered as the locking projection 62 is inserted into the locking groove 54b. Abutting against the right end of the member pressing wall 52, the side wall 69 is pushed outward along the chamfered portion 61a as the case lid member 60 slides. As shown in FIG. 11B, in a state where the locking projection 62 is completely inserted into the locking groove 54b, the outer surface of the side wall 69 and the inner surface of the second wall 53b are in close contact. The pressing protrusion 61 is sandwiched between the second wall portion 53 b and the lid member pressing wall 52. Therefore, when the locking projection 62 is inserted into the insertion groove 54a, the distance between the second wall 53b and the wall member pressing wall 52 is sufficiently wider than the thickness of the side wall 69. 50 and the opening of the case lid member 60 can be smoothly aligned, but the case lid member 60 is slid with respect to the case main body member 50 so that the locking projection 62 and the lid member mounting groove 54 When the two are engaged, the side wall 69 and the second wall 53b are in close contact with each other, and the clearance between them can be reduced (almost eliminated).

ケース本体部材５０とケース蓋部材６０とを以上のように構成すると、このケース本体部材５０にケース蓋部材６０を取り付けたときに、係止突起部６２が蓋部材取付溝５４と嵌合するため、ケース蓋部材６０はケース本体部材５０に対して後方への移動（ケース本体部材５０からケース蓋部材６０を外すための移動）が規制される。また、ケース蓋部材６０の側壁部６９は、押圧突起部６１と蓋部材押圧壁５２とによりケース本体部材５０の第２壁部５３ｂの内側面に押しつけられて密接しているため、側壁部６９を内側に押し込むことができず、係止突起部６２を蓋部材取付溝５４から外すことができない。また、側壁部６９と第２壁部５３ｂとの間のクリアランスがほとんどないため、ドライバ等を挿入して内部の主制御基板３１を操作することや、係止突起部６２または蓋部材取付溝５４を削ることもできない。さらに、上述のように、ケース本体部材５０の側壁部５３の外側面には、蓋部材取付溝５４の側壁部５４ｄと補強用のリブ５４ｅとが形成されているため、この側壁部５３を外側に押し広げることができず、係止突起部６２を蓋部材取付溝５４から外すことや、上記クリアランスを大きくしてドライバ等を挿入することもできない。 When the case body member 50 and the case lid member 60 are configured as described above, the locking projection 62 is fitted into the lid member mounting groove 54 when the case lid member 60 is attached to the case body member 50. The case lid member 60 is restricted from moving backward with respect to the case body member 50 (movement for removing the case lid member 60 from the case body member 50). Further, since the side wall 69 of the case lid member 60 is pressed against and closely contacts the inner surface of the second wall 53 b of the case body member 50 by the pressing protrusion 61 and the lid member pressing wall 52, the side wall 69. Cannot be pushed inward, and the locking projection 62 cannot be removed from the lid member mounting groove 54. Moreover, since there is almost no clearance between the side wall part 69 and the 2nd wall part 53b, a driver etc. are inserted and the internal main control board 31 is operated, and the latching protrusion part 62 or the lid member attachment groove 54 is inserted. You can't even shave. Furthermore, as described above, the side wall portion 54d of the lid member mounting groove 54 and the reinforcing rib 54e are formed on the outer surface of the side wall portion 53 of the case body member 50. The locking projection 62 cannot be removed from the lid member mounting groove 54, and the driver cannot be inserted with the clearance increased.

ここで、ケース本体部材５０の左端側には本体側仮止部５５が形成されており、ケース蓋部材６０の左端側には蓋側仮止部６３が形成されている。ケース本体部材５０にケース蓋部材６０が取り付けられたとき、すなわち、ケース本体部材５０に対してケース蓋部材６０が左方向にスライド移動して取り付けられたときに、これらの本体側仮止部５５と蓋側仮止部６３との位置は一致して係合し、ケース蓋部材６０がケース本体部材５０に対して右方向にスライド移動するのを規制する。なお、ケース本体部材５０およびケース蓋部材６０は、上述のように、樹脂材料で形成されており、これらの本体側仮止部５５および蓋側仮止部６３は薄く形成されているため、容易に撓めることができる。そのため、蓋側仮止部６３の左端側を本体側仮止部５５から離すように撓めることにより本体側仮止部５５と蓋側仮止部６３との係合は解除され、ケース本体部材５０に対して、ケース蓋部材６０を右方にスライド移動して、このケース蓋部材６０をケース本体部材５０から取り外すことができる。 Here, a main body side temporary fixing portion 55 is formed on the left end side of the case main body member 50, and a lid side temporary fixing portion 63 is formed on the left end side of the case lid member 60. When the case lid member 60 is attached to the case body member 50, that is, when the case lid member 60 is slid and attached to the case body member 50 in the left direction, these body side temporary fixing portions 55 are attached. And the lid-side temporary fixing portion 63 are engaged with each other, and the case lid member 60 is restricted from sliding to the right with respect to the case body member 50. Note that the case body member 50 and the case lid member 60 are formed of a resin material as described above, and the body side temporary fixing portion 55 and the lid side temporary fixing portion 63 are formed thin, so that it is easy. Can be bent. Therefore, by bending the left end side of the lid side temporary fixing part 63 away from the main body side temporary fixing part 55, the engagement between the main body side temporary fixing part 55 and the lid side temporary fixing part 63 is released, and the case body The case lid member 60 can be detached from the case body member 50 by sliding the case lid member 60 to the right with respect to the member 50.

このように、主制御基板３１が収容される主基板ケース１００を、互いに分離できるケース本体部材５０とケース蓋部材６０とに分けて構成することにより、主制御基板３１をケース蓋部材６０に取り付けるときは、このケース蓋部材６０の開口部を上方に向けて作業机等に載置した状態で行うことができるので、取り付け作業が容易になり組み立ての作業効率が向上する。また、ケース蓋部材６０をケース本体部材５０に取り付けるときも、スライド移動だけで取り付けることができるので、この作業も容易である。また、このようにケース本体部材５０にケース蓋部材６０をスライドして取り付ける構成にすると、ケース本体部材５０側に蓋部材取付溝５４を形成し、ケース蓋部材６０に係止突起部６２を形成することで取り付け構造ができるため、主基板ケース１００の構造を簡単にすることができる。 In this way, the main board case 100 in which the main control board 31 is accommodated is divided into the case main body member 50 and the case lid member 60 that can be separated from each other, thereby attaching the main control board 31 to the case lid member 60. At this time, since the opening of the case lid member 60 can be mounted on a work desk or the like with the opening facing upward, the mounting work is facilitated and the assembly work efficiency is improved. Also, when attaching the case lid member 60 to the case main body member 50, the case lid member 60 can be attached only by sliding movement, so this operation is also easy. Further, when the case lid member 60 is slid and attached to the case body member 50 in this manner, the lid member attachment groove 54 is formed on the case body member 50 side, and the locking projection 62 is formed on the case lid member 60. By doing so, the mounting structure can be made, so that the structure of the main board case 100 can be simplified.

以上のように、主制御基板３１は、主基板ケース１００（ケース本体部材５０およびケース蓋部材６０）内に格納されているため、主制御基板３１に対する不正行為を防止することができる。しかしながら、ケース本体部材５０に対してケース蓋部材６０が取り付けられた状態にあるときは、本体側仮止部５５と蓋側仮止部６３とが係合しているだけであり、ケース本体部材５０からケース蓋部材６０を取り外すことは容易である。そこで、閉止状態にあるケース蓋部材６０をケース本体部材５０に対してスライド移動できなくして不正操作を防止するために、主基板アッセンブリ３０の主基板ケース１００には不正開放防止機構７０が設けられている。そこで、図１２〜図１９を追加参照して主基板アッセンブリ３０に設けられた不正開放防止機構７０について以下に詳しく説明する。 As described above, since the main control board 31 is stored in the main board case 100 (the case main body member 50 and the case lid member 60), an illegal act on the main control board 31 can be prevented. However, when the case lid member 60 is attached to the case body member 50, the body side temporary fastening portion 55 and the lid side temporary fastening portion 63 are merely engaged, and the case body member It is easy to remove the case lid member 60 from 50. Therefore, in order to prevent the case lid member 60 in the closed state from slidingly moving with respect to the case body member 50 and preventing unauthorized operation, the main substrate case 100 of the main substrate assembly 30 is provided with an unauthorized opening prevention mechanism 70. ing. Therefore, the unauthorized opening prevention mechanism 70 provided in the main board assembly 30 will be described in detail below with reference to FIGS.

不正開放防止機構７０は、図４等に示すように、ケース本体部材５０の左端側に連結して一体に形成された４つの本体側係合部５６と、ケース蓋部材６０の左端側に連結して形成された４つの蓋側係合部６４と、蓋側係合部６４に挿入されて、ケース本体部材５０にケース蓋部材６０を固定保持する４つのストッパ部材７１とから構成される。 As shown in FIG. 4 and the like, the unauthorized opening prevention mechanism 70 is connected to the left end side of the case lid member 60 and the four main body side engaging portions 56 integrally formed by connecting to the left end side of the case main body member 50. The four lid-side engaging portions 64 are formed, and the four stopper members 71 are inserted into the lid-side engaging portion 64 and hold the case lid member 60 on the case body member 50.

本体側係合部５６は、図６および図１２（ａ）に示すように、ケース本体部材５０にケース蓋部材６０が取り付けられたときに蓋側係合部６４の各々に覆われる係合底部５６ａと、この係合底部５６ａの上下方向縁部および左方向縁部から前方に延び、ケース本体部材５０にケース蓋部材６０が取り付けられたときに蓋側係合部６４の開口部の周りを外側から覆う係合壁部５６ｂとから構成され、係合底部５６ａの略中央部には凹状の第１係合凹部５６ｃと凹状の第１爪待避凹部５６ｆが左右方向に並んで形成されている。また、第１係合凹部５６ｃおよび第２爪待避凹部５６ｆを挟むように、２つの第２係合凹部５６ｄ，５６ｄおよび第２爪待避凹部５６ｈ，５６ｈの組がそれぞれ左右方向に延びて形成されている。さらに、係合壁部５６ｂの右方先端部には、右方に開口し、ケース本体部材５０にケース蓋部材６０が取り付けられたときに蓋側係合部６４を抑える係合保持部５６ｅが形成されている。 As shown in FIGS. 6 and 12A, the main body side engaging portion 56 is an engagement bottom portion that is covered with each of the lid side engaging portions 64 when the case lid member 60 is attached to the case main body member 50. 56a and the front and left edges of the engagement bottom portion 56a extend forward and around the opening of the lid-side engagement portion 64 when the case lid member 60 is attached to the case body member 50. The engaging wall portion 56b covers from the outside, and a concave first engaging concave portion 56c and a concave first claw retracting concave portion 56f are formed side by side in the left-right direction at a substantially central portion of the engaging bottom portion 56a. . Further, a pair of two second engagement recesses 56d and 56d and second claw recesses 56h and 56h are formed to extend in the left-right direction so as to sandwich the first engagement recess 56c and the second claw retracting recess 56f. ing. Furthermore, an engagement holding portion 56e that opens to the right at the right end portion of the engagement wall portion 56b and holds the lid side engagement portion 64 when the case lid member 60 is attached to the case body member 50. Is formed.

一方、蓋側係合部６４は、前方側（図３に示す状態で、ケース本体部材５０にケース蓋部材６０が取り付けられたときに、本体側係合部５６と対向する側）が開口した矩形箱状に形成され、内部にストッパ挿入空間６４ａが形成されている。なお、図８および図１３に示すように、ケース蓋部材６０において主制御基板３１を収納する領域を形成する左側の側壁部６５と蓋側係合部６４との間は、２本の蓋側連結部６６で連結されている。この蓋側連結部６６は切断可能に構成されており、ケース蓋部材６０から蓋側係合部６４を分離可能である。また、上下方向両側部には外方に突出して上述の係合保持部５６ｅと嵌合する係合突起部６４ｂが左右方向に延びて形成されている。この係合突起部６４ｂの右端には、後方に折曲して延びるカバー部６４ｅが形成されている。さらに、左側側面と上下の側面から外方にフランジ状に突出するフランジ部６４ｄが形成されている。このフランジ部６４ｄは薄い板状に形成されている。 On the other hand, the lid side engaging portion 64 is opened on the front side (the side facing the main body side engaging portion 56 when the case lid member 60 is attached to the case main body member 50 in the state shown in FIG. 3). It is formed in a rectangular box shape, and a stopper insertion space 64a is formed inside. As shown in FIGS. 8 and 13, there are two lid sides between the left side wall portion 65 and the lid side engaging portion 64 that form a region for housing the main control board 31 in the case lid member 60. They are connected by a connecting part 66. The lid side connecting portion 66 is configured to be cuttable, and the lid side engaging portion 64 can be separated from the case lid member 60. In addition, on both side portions in the vertical direction, engagement protrusions 64b that protrude outward and fit with the above-described engagement holding portion 56e are formed extending in the left-right direction. At the right end of the engaging protrusion 64b, a cover portion 64e is formed that bends and extends rearward. Further, a flange portion 64d is formed to protrude outwardly from the left side surface and the upper and lower side surfaces in a flange shape. The flange portion 64d is formed in a thin plate shape.

ストッパ部材７１は、樹脂等からなり矩形箱状に形成されており、図１４に示すように、矩形箱状の外側部材８０と矩形箱状の内側部材９０とが組み合わされて構成されている。外側部材８０は、一方の面が開口した箱状に形成されている。そして、この開口部と対向する底面８１には、第１係合爪部８３が形成されている。この第１係合爪部８３は、底面８１から外方に突出するように形成されており、この第１係合爪部８３を挟むように、底面８１を貫通する切れ込み部８２，８２が形成されている。第１係合爪部８３は、切れ込み部８２に沿って、底面８１から外側になだらかに傾斜する傾斜面８３ａを有し、先端側は、底面８１に対して略垂直な係合面８３ｂを有している。また、この底面８２には、第１係合爪部８３を挟むように外方に突出し、第１係合爪部８３ａと同様の形状を有した第２係合爪部８４，８４が形成されている。なお、第２係合爪部８４の幅方向大きさは、第１係合爪部８３の幅方向大きさより小さく形成されている。一方、内側部材９０は、一方の面が開口した箱状に形成されており、側面９１には、外方に突出する係止突起部９２が形成されている。以上のように構成された外側部材８０の開口部に対して、内側部材９０を、開口部側から挿入して組み立てると、第１および第２係合爪部８３，８４，８４および係止突起部９２が外方に突出する。 The stopper member 71 is made of a resin or the like and is formed in a rectangular box shape. As shown in FIG. 14, the stopper member 71 is configured by combining a rectangular box-shaped outer member 80 and a rectangular box-shaped inner member 90. The outer member 80 is formed in a box shape with one surface opened. A first engaging claw portion 83 is formed on the bottom surface 81 facing the opening. The first engaging claw portion 83 is formed so as to protrude outward from the bottom surface 81, and notches 82 and 82 penetrating the bottom surface 81 are formed so as to sandwich the first engaging claw portion 83. Has been. The first engaging claw portion 83 has an inclined surface 83 a that gently slopes outward from the bottom surface 81 along the cut portion 82, and the distal end side has an engaging surface 83 b that is substantially perpendicular to the bottom surface 81. is doing. Further, the bottom surface 82 is formed with second engagement claw portions 84 and 84 that protrude outward and sandwich the first engagement claw portion 83 and have the same shape as the first engagement claw portion 83a. ing. The size in the width direction of the second engagement claw portion 84 is smaller than the size in the width direction of the first engagement claw portion 83. On the other hand, the inner member 90 is formed in a box shape in which one surface is opened, and a locking projection 92 that protrudes outward is formed on the side surface 91. When the inner member 90 is inserted into the opening of the outer member 80 configured as described above and assembled from the opening side, the first and second engaging claws 83, 84, 84 and the locking projection The part 92 protrudes outward.

ストッパ部材７１は、図１５および図１６に示すように、蓋側係合部６４のストッパ挿入空間６４ａ内に挿入されて用いられる。まず、ケース本体部材５０に取り付けられたケース蓋部材６０の右方向へのスライド移動を規制するため（これを「係止状態」と呼ぶ）には、図１５に示すように、ストッパ部材７１の第１係合爪部８３および第２係合爪部８４，８４（図１４，図１５においては、第１係合爪部８３のみを示す）が下方に向き、かつ、この第１係合爪部８３（および第２係合爪部８４，８４）の傾斜面８３ａが左方（ケース蓋部材６０をケース本体部材５０に取り付けるときにスライド移動させる方向）に位置するように蓋側係合部６４に挿入する（このストッパ部材７１の状態を「ロック状態」と呼ぶ）。なお、ストッパ部材７１が蓋側係合部６４に挿入されると、ストッパ部材７１の係止突起部９２が蓋側係合部６４のストッパ挿入空間６４ａを形成する内側の壁に押しつけられて弾性で付勢するため、この蓋側係合部６４の開口部が下方を向けられても、ストッパ部材７１は容易に脱落しない。 As shown in FIGS. 15 and 16, the stopper member 71 is used by being inserted into the stopper insertion space 64 a of the lid side engaging portion 64. First, in order to restrict the sliding movement of the case lid member 60 attached to the case main body member 50 in the right direction (this is referred to as “locking state”), as shown in FIG. The first engagement claw portion 83 and the second engagement claw portions 84 and 84 (only the first engagement claw portion 83 is shown in FIGS. 14 and 15) are directed downward, and the first engagement claw The lid-side engaging portion so that the inclined surface 83a of the portion 83 (and the second engaging claw portions 84, 84) is located to the left (the direction in which the case lid member 60 is slid when the case lid member 60 is attached to the case body member 50). (The state of the stopper member 71 is referred to as “locked state”). When the stopper member 71 is inserted into the lid-side engagement portion 64, the locking projection 92 of the stopper member 71 is pressed against the inner wall forming the stopper insertion space 64a of the lid-side engagement portion 64 to be elastic. Therefore, even if the opening of the lid side engaging portion 64 is directed downward, the stopper member 71 does not easily fall off.

このような状態で、ケース蓋部材６０の係止突起部６２をケース本体部材５０の蓋部材取付溝５４に挿入すると、ストッパ部材７１の第１係合爪部８３は、第１爪待避凹部５６ｆに位置し、第２係合爪部８４，８４は第２爪待避凹部５６ｈ，５６ｈに位置するため、これらの第１係合爪部８３および第２係合爪部８４，８４が上方に押し上げられることがなく、その結果として、蓋側係合部６４も押し上げられず、蓋側係合部６４の前端面（開口部）と本体側係合部５６の係合底部５６ａとは当接している。そして、ケース蓋部材６０をケース本体部材５０に対して左方にスライド移動すると、ストッパ部材７１の第１係合爪部８３が、傾斜面８３ａに沿って第１爪待避凹部５６ｆの左端側に形成された傾斜面５６ｋにより押し上げられながら第１係止爪部８３が左方に移動する。同様に、第２係合爪部８４，８４も第２爪待避凹部５６ｈの左端側に形成された傾斜面５６ｍにより上方に押し上げられながら左方に移動する。このとき、図１７および図１８に示すように、第１および第２係合爪部８３，８４，８４が押し上げられる前に、蓋側係合部６４に形成された係合突起部６４ｂが、その左端部から本体側係合部５６に形成された係合保持部５６ｅに挿入されるため、第１および第２係止爪部８３，８４，８４が押し上げられても係合保持部５６ｅおよび係合突起部６４ｂにより上方への移動が規制され、蓋側係合部６４が押し上げられることはない。 In this state, when the locking projection 62 of the case lid member 60 is inserted into the lid member mounting groove 54 of the case main body member 50, the first engagement claw portion 83 of the stopper member 71 becomes the first claw retracting recess 56f. Since the second engagement claw portions 84 and 84 are located in the second claw retracting recesses 56h and 56h, the first engagement claw portion 83 and the second engagement claw portions 84 and 84 are pushed upward. As a result, the lid side engaging portion 64 is not pushed up, and the front end surface (opening) of the lid side engaging portion 64 and the engaging bottom portion 56a of the main body side engaging portion 56 are in contact with each other. Yes. When the case lid member 60 is slid to the left with respect to the case body member 50, the first engaging claw portion 83 of the stopper member 71 is moved to the left end side of the first claw retracting recess 56f along the inclined surface 83a. The first locking claw portion 83 moves to the left while being pushed up by the formed inclined surface 56k. Similarly, the second engaging claw portions 84 and 84 also move to the left while being pushed upward by the inclined surface 56m formed on the left end side of the second claw retracting recess 56h. At this time, as shown in FIGS. 17 and 18, before the first and second engaging claws 83, 84, 84 are pushed up, the engaging protrusion 64 b formed on the lid side engaging portion 64 is Since the left end portion is inserted into the engagement holding portion 56e formed on the main body side engagement portion 56, the engagement holding portion 56e and the first and second locking claws 83, 84, 84 are pushed up. The upward movement is restricted by the engaging protrusion 64b, and the lid side engaging portion 64 is not pushed up.

そして、蓋側係合部６４と本体側係合部５６とが重なった位置になると、第１係合爪部８３と第１係合凹部５６ｃとの位置が一致し、また、第２係合爪部８４，８４と第２係合凹部５６ｄ，５６ｄとの位置が一致して押し上げられていた第１係合爪部８３および第２係合爪部８４，８４が弾性で第１係合凹部５６ｃおよび第２係合凹部５６ｄ，５６ｄに入り込み、第１および第２係合凹部５６ｃ，５６ｄ，５６ｄと第１および第２係合爪部８３，８４，８４とが係合し、さらに、係合突起部６４ｂと係合保持部５６ｅとが嵌合して、本体側係合部５６と蓋側係合部６４とが係合する。この状態になると、ケース蓋部材６０を右方にスライド移動させようとしても、第１係合爪部８３の係合面８３ｂが第１係合凹部５６ｃと係合しており（第２係合爪部８４，８４も同様）、この係合面８３ｂは第１係合凹部５６の壁に沿って延びているため（第２係合爪部８４，８４も同様）、第１および第２係合爪部８３，８４，８４が上方に押し上げられることはなく、また、係合突起部６４ｂと係合保持部５６ｅとが嵌合されているため蓋側係合部６４を本体側係合部５６から引き離すことができず、第１および第２係合凹部５６ｃ，５６ｄ，５６ｄから第１および第２係合爪部８３，８４，８４が外れることはない。そのため、本体側係合部５６と蓋側係合部６４とは固定され、ケース本体部材５０に対してケース蓋部材６０を固定保持する（係止状態にする）ことができる。 When the lid side engaging portion 64 and the main body side engaging portion 56 are overlapped, the positions of the first engaging claw portion 83 and the first engaging concave portion 56c coincide with each other, and the second engaging portion is engaged. The first engagement claw portion 83 and the second engagement claw portions 84, 84 that have been pushed up with the positions of the claw portions 84, 84 and the second engagement recesses 56 d, 56 d aligned are elastic and the first engagement recess 56c and the second engagement recesses 56d and 56d, the first and second engagement recesses 56c, 56d and 56d engage with the first and second engagement claws 83, 84 and 84, and the engagement The mating protrusion 64b and the engagement holding part 56e are fitted, and the main body side engaging part 56 and the lid side engaging part 64 are engaged. In this state, even if the case lid member 60 is slid to the right, the engagement surface 83b of the first engagement claw 83 is engaged with the first engagement recess 56c (second engagement). Since the engaging surface 83b extends along the wall of the first engaging recess 56 (the same applies to the second engaging claw portions 84, 84), the first and second engagement portions 83 and 84 have the same structure. The claw portions 83, 84, 84 are not pushed upward, and the engagement protrusion 64b and the engagement holding portion 56e are fitted, so that the lid side engagement portion 64 is moved to the body side engagement portion. 56 cannot be separated from the first and second engaging recesses 56c, 56d, and 56d, and the first and second engaging claws 83, 84, and 84 are not detached. Therefore, the main body side engaging portion 56 and the lid side engaging portion 64 are fixed, and the case lid member 60 can be fixedly held (locked) with respect to the case main body member 50.

一方、図１６に示すように、蓋側係合部６４に対して、第１係合爪部８３（第２係合爪部８４，８４も同様）がこの蓋側係合部６４内に位置するように挿入された場合（第１および第２係合爪部８３，８４，８４が上方を向いた状態に挿入された場合であって、この状態を「アンロック状態」と呼ぶ）には、本体側係合部５６と蓋側係合部６４とは係合せず、ケース本体部材５０に対してケース蓋部材６０は右方にスライド移動可能となる（この状態を「解除状態」と呼ぶ）。 On the other hand, as shown in FIG. 16, the first engagement claw portion 83 (the same applies to the second engagement claw portions 84 and 84) is located in the lid side engagement portion 64 with respect to the lid side engagement portion 64. (When the first and second engaging claws 83, 84, 84 are inserted in a state of facing upward, this state is referred to as an “unlocked state”) The body-side engaging portion 56 and the lid-side engaging portion 64 are not engaged, and the case lid member 60 is slidable to the right with respect to the case body member 50 (this state is referred to as a “released state”). ).

このようにして、ケース蓋部材６０をケース本体部材５０に対してスライド移動させて蓋側係合部６４が本体側係合部５６と対向して重なる状態にすると、第１および第２係合爪部８３，８４，８４と第１および第２係合凹部５６ｃ，５６ｄ，５６ｄとが係合して本体側係合部５６と蓋側係合部６４とが係止保持され、ケース本体部材５０に対するケース蓋部材６０の右方向へのスライド移動が規制される。そのため、ケース本体部材５０にケース蓋部材６０が装着された状態、すなわち、係止状態が保持される。これにより、本体側係合部５６と蓋側係合部６４とをストッパ部材７１を介して容易に連結させることができ、ケース本体部材５０とケース蓋部材６０とを閉止状態で容易に結合保持することができる。 In this way, when the case lid member 60 is slid relative to the case body member 50 so that the lid side engaging portion 64 overlaps the body side engaging portion 56, the first and second engagements are achieved. The claw portions 83, 84, 84 and the first and second engaging recesses 56c, 56d, 56d are engaged, and the main body side engaging portion 56 and the lid side engaging portion 64 are locked and held, and the case main body member The sliding movement of the case lid member 60 with respect to 50 in the right direction is restricted. Therefore, the state where the case lid member 60 is attached to the case body member 50, that is, the locked state is maintained. Thereby, the main body side engaging portion 56 and the lid side engaging portion 64 can be easily coupled via the stopper member 71, and the case main body member 50 and the case lid member 60 are easily coupled and held in the closed state. can do.

以上のように、本実施例に係る不正開放防止機構７０は、ストッパ部材７１に３個の係合爪部（第１および第２係合爪部８３，８４，８４）を設けており、それぞれを、係合凹部（第１および第２係合凹部５６ｃ，５６ｄ，５６ｄ）と係合させているため、ケース本体部材５０とケース蓋部材６０とを確実に係合保持することができる。なお、図１２（ａ）に示すように、第２爪待避凹部５６ｈの左端側に形成された傾斜面５６ｍは、第１爪待機凹部５６ｆの左端側に形成された傾斜面５６ｋより、やや右方に位置している。また、図１４に示すように、第２係合爪部８４，８４の高さは、第１係合爪部８３の高さより低くなるように形成されている。そのため、ケース本体部材５０にケース蓋部材６０をスライド移動して取り付けるときは、先に第２係合爪部８４，８４が、第１係合爪部８３が第１係合凹部５６ｃと係合するより先に、第２係合凹部５６ｄ，５６ｄと嵌合するため、これらの係合爪部８３，８４，８４の係合タイミングがずれるので、係合時に荷重を分散させることができ、スムーズにケース本体部材５０にケース蓋部材６０を取り付けることができる。 As described above, the unauthorized opening prevention mechanism 70 according to the present embodiment is provided with the three engaging claws (first and second engaging claws 83, 84, 84) on the stopper member 71, respectively. Is engaged with the engagement recesses (first and second engagement recesses 56c, 56d, 56d), the case main body member 50 and the case lid member 60 can be reliably engaged and held. In addition, as shown to Fig.12 (a), the inclined surface 56m formed in the left end side of the 2nd nail | claw retracting recessed part 56h is a little right from the inclined surface 56k formed in the left end side of the 1st nail | claw waiting recessed part 56f. It is located in the direction. Further, as shown in FIG. 14, the height of the second engagement claw portions 84 and 84 is formed to be lower than the height of the first engagement claw portion 83. Therefore, when the case cover member 60 is slid and attached to the case body member 50, the second engagement claw portions 84 and 84 are first engaged with the first engagement claw portion 83 and the first engagement recess portion 56c. Since the engagement with the second engagement recesses 56d, 56d is shifted before the engagement, the engagement timing of the engagement claws 83, 84, 84 is shifted, so that the load can be dispersed during the engagement, and the smooth The case lid member 60 can be attached to the case body member 50.

そして、このような不正開放防止機構７０によりケース本体部材５０とケース蓋部材６０とが閉止状態で結合保持されれば、本体側係合部５６と係合したストッパ部材７１との係合を解除するのは非常に困難であり、主基板ケース１００（主基板アッセンブリ３０）を開くためには、蓋側連結部６６を切断して蓋側係合部６４をケース蓋部材６０から切り離す必要がある。そのため、主基板ケース１００の開放後は、蓋側連結部６６の切断痕跡が明確に残るため、不正な開放を早期に発見することができるとともに、不正行為を効果的に抑止できる。また、不正開放防止機構７０を解除状態から係止状態にするには、蓋側係合部６４に対してストッパ部材７１の第１および第２係合爪部８３，８４，８４の向きを変える（アンロック状態で蓋側係合部６４に挿入されているストッパ部材７１を取り出してロック状態に入れ替える）だけで良いため、作業も非常に容易である。 If the case main body member 50 and the case lid member 60 are coupled and held in a closed state by the unauthorized opening prevention mechanism 70, the engagement with the stopper member 71 engaged with the main body side engaging portion 56 is released. In order to open the main board case 100 (the main board assembly 30), it is necessary to cut the lid side connecting portion 66 and separate the lid side engaging portion 64 from the case lid member 60. . For this reason, after the main board case 100 is opened, the cutting trace of the lid-side connecting portion 66 remains clearly, so that it is possible to detect unauthorized opening at an early stage and to effectively prevent unauthorized actions. In addition, in order to change the unauthorized opening prevention mechanism 70 from the released state to the locked state, the orientation of the first and second engaging claws 83, 84, 84 of the stopper member 71 is changed with respect to the lid side engaging portion 64. Since it is only necessary to take out the stopper member 71 inserted in the lid side engaging portion 64 in the unlocked state and replace it with the locked state, the operation is very easy.

なお、本実施例においては、不正開放防止機構７０は、本体側係合部５６、蓋側係合部６４、および、ストッパ部材７１の組を４組有しており、主基板ケース１００をこの不正開放防止機構７０で結合保持するためには、いずれか一つのストッパ部材７１をロック状態、すなわち、第１および第２係合爪部８３，８４，８４が蓋側係合部６４に対して図３の状態で前方に突出するようにして挿入されていれば良い。そのため、例えば、主制御基板３１を検査するために、閉止状態（係止状態）の主基板ケース１００が開放されても、別の不正開放防止機構７０の組を用いて閉止状態（係止状態）にすることができる。また、切り取られた蓋側係合部６４の数により主基板ケース１００が何回開放されたかを確認することができる。 In the present embodiment, the unauthorized opening prevention mechanism 70 has four sets of the main body side engaging portion 56, the lid side engaging portion 64, and the stopper member 71. In order to be coupled and held by the unauthorized opening prevention mechanism 70, any one stopper member 71 is locked, that is, the first and second engaging claws 83, 84, 84 are in contact with the lid side engaging portion 64. What is necessary is just to insert so that it may protrude ahead in the state of FIG. Therefore, for example, even if the main board case 100 in the closed state (locked state) is opened in order to inspect the main control board 31, the closed state (locked state) is used by using another set of the unauthorized opening prevention mechanism 70. ). Moreover, it can be confirmed how many times the main board case 100 is opened by the number of the lid-side engaging portions 64 cut out.

また、ストッパ部材７１を構成する外側部材８０および内側部材９０を、それぞれ異なる色の樹脂で形成しておくことにより（例えば、外側部材８０を白色、内側部材９０を赤色）、ケース蓋部材６０は透明の樹脂で成形されているため、ストッパ部材７１の挿入状態がロック状態（内側部材９０が上側にあり赤色が蓋側係合部６４を透して見える状態）であるか、上方を向いたアンロック状態（外側部材８０が上側にあり白色が蓋側係合部６４を透して見える状態）であるか、を容易に識別することができる。あるいは、内側部材９０の面９３に「ロック」等の文字を表示しておくことにより、ロック状態のときは透明な蓋側係合部６４を通してこの文字を確認することができ、ロック状態を識別することができる。このとき、４組の不正開放防止機構７０のうち、何番目を使用しているか（若しくは、何番目のものが切断されているか）を目視により確認可能なように、本体側係合部５６の右端側に本体側番号表示部５６ｇが形成されている。同様に、本体側係合部５６の本体側番号表示部５６ｇに対応する番号が表示された蓋側番号表示部６４ｃが、ケース蓋部材６０の蓋側係合部６４の背面側の係合突起部６４ｂの近傍に形成されている。これにより、どのストッパ部材７１をロック状態にするのかを容易に判断することができる。 Further, by forming the outer member 80 and the inner member 90 constituting the stopper member 71 with resins of different colors (for example, the outer member 80 is white and the inner member 90 is red), the case lid member 60 is Since it is molded with a transparent resin, the stopper member 71 is inserted in a locked state (the inner member 90 is on the upper side and the red color is seen through the lid side engaging portion 64) or faced upward. It can be easily identified whether it is in the unlocked state (the outer member 80 is on the upper side and white is seen through the lid side engaging portion 64). Alternatively, by displaying a character such as “lock” on the surface 93 of the inner member 90, this character can be confirmed through the transparent lid side engaging portion 64 in the locked state, and the locked state is identified. can do. At this time, of the four sets of unauthorized opening prevention mechanisms 70, the main body side engaging portion 56 can be visually confirmed as to which number is used (or what number is cut). A main body side number display portion 56g is formed on the right end side. Similarly, the lid-side number display portion 64c on which the number corresponding to the body-side number display portion 56g of the body-side engagement portion 56 is displayed is the engagement protrusion on the back side of the lid-side engagement portion 64 of the case lid member 60. It is formed in the vicinity of the portion 64b. Thereby, it can be easily determined which stopper member 71 is to be locked.

また、前述したように、主基板ケース１００（ケース本体部材５０およびケース蓋部材６０）の材料として透明な樹脂材料を使用しているが、その中でもＡＢＳ樹脂を使用することが好ましい。これにより、上記のような部材に対して切断操作を行うと、ＡＢＳ樹脂の成分であるブタジエンがゴム性を有して伸び、部材が割れずに白色化しやすいため、その切断痕跡が明確に残りやすいという効果が得られる。また、主基板ケース１００を無理にこじ開けようとしても、同様に部材が白色化して（こじ開けた）痕跡が明確に残りやすいという効果が得られる。このとき、図１９に示すように、蓋側係合部６４の開口部周辺は本体側係合部５６の係合壁部５６ｂに覆われており、さらに、蓋側係合部６４の側面に形成されたフランジ部６４ｄが係合壁部５６ｂの後端部を覆うように当接する。また同様に、蓋側係合部６４に形成された係合突起部６４ｂの右端部からＬ字状に折曲して形成されたカバー部６４ｅが係合壁部５６ｂの右端面と当接するように構成されている。そのため、本体側係合部５６と蓋側係合部６４との隙間からドライバ等を挿入して、ストッパ部材７１を操作するのは困難である。また、ストッパ部材７１の第１係合爪部８３は第２係合爪部８４，８４で挟まれているため、係止状態をこじ開けようとするときに第１係合爪部８３を操作することが困難である。いずれの場合も、無理に操作しようとすると、フランジ部６４ｄ、係合突起部６４ｂ、または、蓋側連結部６６等が白色化するため、不正操作を容易に発見することができる。 Further, as described above, a transparent resin material is used as the material of the main substrate case 100 (the case body member 50 and the case lid member 60). Among them, it is preferable to use an ABS resin. As a result, when the cutting operation is performed on the member as described above, the butadiene, which is a component of the ABS resin, has a rubber property, and the member is easily whitened without being cracked. The effect is easy. Further, even if the main board case 100 is forcibly opened, an effect is obtained in which the member is similarly whitened and the trace is easily left clearly. At this time, as shown in FIG. 19, the periphery of the opening of the lid side engaging portion 64 is covered with the engaging wall portion 56 b of the main body side engaging portion 56, and further on the side surface of the lid side engaging portion 64. The formed flange portion 64d abuts so as to cover the rear end portion of the engagement wall portion 56b. Similarly, a cover portion 64e formed by bending an L-shape from the right end portion of the engagement projection portion 64b formed on the lid side engagement portion 64 comes into contact with the right end surface of the engagement wall portion 56b. It is configured. For this reason, it is difficult to operate the stopper member 71 by inserting a screwdriver or the like through the gap between the main body side engaging portion 56 and the lid side engaging portion 64. Further, since the first engagement claw portion 83 of the stopper member 71 is sandwiched between the second engagement claw portions 84 and 84, the first engagement claw portion 83 is operated when trying to pry open the locked state. Is difficult. In any case, if the operation is forcibly performed, the flange portion 64d, the engagement projection portion 64b, the lid side connection portion 66, or the like is whitened, so that an unauthorized operation can be easily found.

また、ケース本体部材５０の本体側係合部５６の裏面側（図３の状態において、前方側の面）には、図１２（ｂ）に示すように格子状にリブ５６ｊが形成されている。そのため、不正開放防止機構７０のロック状態を解除するために、例えば、このケース本体部材５０の裏側を削って、外部から第１および第２係合凹部５６ｃ，５６ｄ，５６ｄに連通する穴を開け、そこから、第１および第２係合爪部８３，８４，８４を押し上げるというような操作を行うことは困難である。なお、上述のように、蓋側係合部６４は透明な材料で形成されているため、ストッパ部材７１も透明な材料で形成することにより、本体側係合部５６の底面５６ａに穴が開けられた場合に発見し易くなる。 Also, ribs 56j are formed in a lattice shape on the back side of the main body side engaging portion 56 of the case main body member 50 (the front side surface in the state of FIG. 3) as shown in FIG. . Therefore, in order to release the locked state of the unauthorized opening prevention mechanism 70, for example, the back side of the case body member 50 is scraped to make holes communicating with the first and second engaging recesses 56c, 56d, and 56d from the outside. From there, it is difficult to perform operations such as pushing up the first and second engaging claws 83, 84, 84. As described above, since the lid side engaging portion 64 is formed of a transparent material, the stopper member 71 is also formed of a transparent material, so that a hole is formed in the bottom surface 56a of the main body side engaging portion 56. It will be easier to discover if

最後に、主基板アッセンブリ３０と画像制御基板アッセンブリ４０の遊技盤１０に対する取り付けおよび取り外し方法について図２０を合わせて用いて説明する。ここで、図２０は、遊技盤１０に対して主基板アッセンブリ３０を揺動させて傾けた場合の斜視図である。 Finally, a method of attaching and removing the main board assembly 30 and the image control board assembly 40 from the game board 10 will be described with reference to FIG. Here, FIG. 20 is a perspective view when the main board assembly 30 is swung and tilted with respect to the game board 10.

遊技盤１０の裏面に取り付けられた主基板取付部１５ａ，１５ｂには、後方に突出し、上方が開口したＵ字状の軸受部１６ａ，１６ｂがそれぞれ設けられている。また、主基板ケース１００のケース本体部材５０には、左右の両側部の下部から左右方向に突出して同軸上に延びる取付軸５７ａ，５７ｂが設けられている。遊技盤１０に主基板アッセンブリ３０を取り付けるときは、図２０に示すように、主基板取付部１５ａ，１５ｂに対して主基板アッセンブリ３０を斜めにして、取付軸５７ａ，５７ｂを上方から軸受部１６ａ，１６ｂの開口に挿入した後、取付軸５７ａ，５７ｂを中心に主基板アッセンブリ３０を前方に揺動させる。 Main board attachment portions 15a and 15b attached to the back surface of the game board 10 are provided with U-shaped bearing portions 16a and 16b that protrude rearward and open upward. In addition, the case body member 50 of the main board case 100 is provided with mounting shafts 57a and 57b that protrude in the left-right direction from the lower portions of the left and right side portions and extend coaxially. When the main board assembly 30 is attached to the game board 10, as shown in FIG. 20, the main board assembly 30 is inclined with respect to the main board attachment portions 15a and 15b, and the attachment shafts 57a and 57b are attached to the bearing portion 16a from above. , 16b, the main board assembly 30 is swung forward about the mounting shafts 57a, 57b.

なお、主基板取付部１５ａ，１５ｂに対する主基板アッセンブリ３０の固定は、ケース本体部材５０の左側部から外方に延びた左側固定部５８に取り付けられた左ナイラッチ３６と、ケース蓋部材６０の右側部から外方に延びた右側固定部６８に取り付けられた右ナイラッチ３７とが用いられる。左右ナイラッチ３６，３７は、例えば図１５に示すように、左ナイラッチ３６の上部に位置する操作部３６ａを下方に押し下げると、下部に位置する張出部３６ｂが外周方向に張り出してその径が大きくなり、操作部３６ａを上方に引き上げると、張出部３６ｂが内周方向に格納されてその径が小さくなるように構成された係止部材である（右ナイラッチ３７も同じ構造である）。 The main board assembly 30 is fixed to the main board mounting portions 15 a and 15 b by fixing the left ny latch 36 attached to the left fixing portion 58 extending outward from the left side portion of the case body member 50 and the right side of the case lid member 60. A right ny latch 37 attached to a right fixing part 68 extending outward from the part is used. For example, as shown in FIG. 15, when the left and right ny latches 36 and 37 are pushed down on the operating portion 36a located at the upper part of the left ny latch 36, the projecting part 36b located at the lower part is projected in the outer peripheral direction and the diameter thereof is increased. Thus, when the operation portion 36a is pulled upward, the overhanging portion 36b is stored in the inner peripheral direction and is a locking member configured so that the diameter thereof is reduced (the right ny latch 37 has the same structure).

左右ナイラッチ３６，３７の操作部（３６ａ）が引き上げられた状態で、上述のように、主基板アッセンブリ３０が取付軸５７ａ，５７ｂを中心に上方に揺動されると、主基板取付部１５ａ，１５ｂの左右ナイラッチ３６，３７に対向する位置に嵌合孔１７ａ，１７ｂが形成されており、この嵌合孔１７ａ，１７ｂに左右ナイラッチ３６，３７の張出部（３６ｂ）が挿入される。この状態で左右ナイラッチ３６，３７の操作部（３６ａ）を押し下げると張出部（３６ｂ）が張り出して主基板アッセンブリ３０が主基板取付部１５ａ，１５ｂに固定される。 As described above, when the main board assembly 30 is swung upward about the mounting shafts 57a and 57b in the state where the operation parts (36a) of the left and right ny latches 36 and 37 are pulled up, the main board mounting parts 15a and 15a, Fitting holes 17a and 17b are formed at positions facing the left and right nai latches 36 and 37 of 15b, and the overhang portions (36b) of the left and right ny latches 36 and 37 are inserted into the fitting holes 17a and 17b. In this state, when the operating portions (36a) of the left and right ny latches 36, 37 are pushed down, the overhanging portion (36b) protrudes and the main board assembly 30 is fixed to the main board mounting portions 15a, 15b.

このとき、主基板取付部１５ａ、１５ｂには、後方に突出する支持突起部１８ａ，１８ｂが形成されており、この支持突起部１８ａ，１８ｂが、ケース本体部材５０の裏面側に形成されたリブ５９により作られる格子に嵌合するため、主基板アッセンブリ３０の荷重は、取付軸５７ａ，５７ｂと左右ナイラッチ３６，３７に加えてこの支持突起部１８ａ，１８ｂで支えられるように構成されている。 At this time, support projections 18a and 18b projecting rearward are formed on the main board mounting portions 15a and 15b. The support projections 18a and 18b are ribs formed on the back side of the case body member 50. In order to fit into the grid formed by 59, the load of the main board assembly 30 is configured to be supported by the support protrusions 18a and 18b in addition to the mounting shafts 57a and 57b and the left and right ny latches 36 and 37.

このように、軸受部１６ａ，１６ｂに対して取付軸５７ａ，５７ｂを中心に揺動させることにより、主基板アッセンブリ３０を後方に揺動させると、画像制御基板アッセンブリ４０の後方側に作業空間を形成することができる。そのため、画像制御基板アッセンブリ４０を後方から覆うように主基板アッセンブリ３０が取り付けられていても、この作業空間を利用して、画像制御基板アッセンブリ４０を遊技盤１０に対して着脱することができ、作業が容易になる。特に、画像制御基板アッセンブリ４０や画像表示装置２３は交換・保守作業が必要となる場合があるため、このように主制御基板アッセンブリ３０を容易に揺動可能にすることにより、これらの作業の効率化を図ることができる。 As described above, when the main board assembly 30 is swung backward by swinging the bearing portions 16a and 16b around the mounting shafts 57a and 57b, a work space is provided on the rear side of the image control board assembly 40. Can be formed. Therefore, even if the main board assembly 30 is attached so as to cover the image control board assembly 40 from the rear, the image control board assembly 40 can be attached to and detached from the game board 10 using this work space. Work becomes easy. In particular, since the image control board assembly 40 and the image display device 23 may require replacement and maintenance work, the main control board assembly 30 can be easily swung in this manner, thereby improving the efficiency of these work. Can be achieved.

以上説明した本発明の実施形態において、達成される主要な効果を整理すれば、下記のようになる。 In the embodiment of the present invention described above, the main effects achieved can be summarized as follows.

第１に、係止突起部６２を蓋部材取付溝５４に挿入するときは、ケース本体部材５０の第２壁部５３ｂと蓋部材押圧壁５２との間は、ケース蓋部材６０の側壁部６９の厚さに比べて十分に広いので、ケース本体部材５０の開口部とケース蓋部材６０の開口部をスムーズに合わせることができる。そして、ケース本体部材５０に対してケース蓋部材６０をスライド移動すると、蓋部材押圧壁５２により押圧突起部６１が外方に押されて、ケース本体部材５０の第２壁部５３ｂとケース蓋部材６０の側壁部６９とが当接するため、ケース本体部材５０とケース蓋部材６０との結合部のクリアランスがほとんどなくなる。そのため、この結合部から内部にドライバ等が挿入されるのを防止することができる。 First, when the locking projection 62 is inserted into the lid member mounting groove 54, the side wall 69 of the case lid member 60 is between the second wall 53 b of the case body member 50 and the lid member pressing wall 52. Therefore, the opening of the case body member 50 and the opening of the case lid member 60 can be smoothly aligned. When the case lid member 60 is slid and moved with respect to the case body member 50, the pressing projection 61 is pushed outward by the lid member pressing wall 52, and the second wall portion 53b of the case body member 50 and the case lid member are pressed. Since the side wall 69 of the 60 abuts, there is almost no clearance at the joint between the case body member 50 and the case lid member 60. Therefore, it is possible to prevent a driver or the like from being inserted into the inside from the coupling portion.

第２に、ケース蓋部材６０の側壁部６９は、蓋部材押圧壁５２および押圧突起部６１によりケース本体部材５０の第２壁部５３ｂに押しつけられているため、このケース蓋部材６０の側壁部６９を内側に押し込んで、係止突起部６２と蓋部材取付溝５４との係合を外す操作を防止することができる。 Second, since the side wall 69 of the case lid member 60 is pressed against the second wall 53b of the case main body member 50 by the lid member pressing wall 52 and the pressing projection 61, the side wall of the case lid member 60 It is possible to prevent the operation of releasing the engagement between the locking projection 62 and the lid member attaching groove 54 by pushing 69 inward.

第３に、押圧突起部６１のスライド移動する方向の面（面取り部６１ａ）をテーパ状に形成することにより、押圧突起部６１は、蓋部材押圧壁５２に対してこの面取り部６１ａで当接するため、テーパ状の面に沿って押圧突起部６１が外方に押し出されるので、ケース本体部材５０に対してケース蓋部材６０をスムーズにスライド移動させることができる。 Third, by forming the surface of the pressing projection 61 in the sliding direction (the chamfered portion 61 a) in a tapered shape, the pressing projection 61 abuts against the lid member pressing wall 52 at the chamfered portion 61 a. Therefore, the pressing protrusion 61 is pushed outward along the tapered surface, and the case lid member 60 can be smoothly slid relative to the case body member 50.

第４に、ケース本体部材５０の蓋部材取付溝５４が形成された第２壁部５３ｂの外側に補強用のリブ５４ｅを形成することにより、このケース本体部材５０の第２壁部５３ｂを外方に押し広げることができず、係止突起部６２と蓋部材取付溝５４との係合を外す操作を防止できる。 Fourth, by forming a reinforcing rib 54e on the outside of the second wall portion 53b in which the lid member mounting groove 54 of the case body member 50 is formed, the second wall portion 53b of the case body member 50 is removed. Therefore, the operation of releasing the engagement between the locking projection 62 and the lid member mounting groove 54 can be prevented.
