Yes. The main board assembly MBA is detachably attached to a bracket BR attached to the back plate 1a of the main body case 1, and at this time, the main board assembly MBA is attached and held using an unauthorized attachment / detachment prevention mechanism DPM2. In the present embodiment, the vertical and horizontal directions in FIG. 3 are the vertical and horizontal directions of the main board assembly MBA, and the direction away from the drawing in FIG. 3 is the front of the main board assembly MBA.

ケース本体部材20は、図6に示すように、前面が開口した矩形箱状に形成された本体側ケース筐体21と、本体側ケース筐体21の上側に繋がって形成された板状の係合ベース部26とを有している。ケース蓋部材30は、図8および図9に示すように、後面が開口した矩形箱状に形成された蓋側ケース筐体31と、蓋側ケース筐体31の右側部に延びて一体に形成された矩形枠部35と、蓋側ケース筐体31の上側に繋がって形成された矩形枠状の収容枠部37とを有し、蓋側ケース筐体31の内側にメイン制御基板16が取り付けられた状態で、ケース本体部材20に閉止装着される。このとき、本体側ケース筐体21と蓋側ケース筐体31との間に形成されるケース空間内にメイン制御基板16が収容される。また、蓋側ケース筐体31の左側面には、ブラケットBRの左側部と嵌合可能な左側方に突出する嵌合突起36が形成されている。メイン制御基板16は、ROM(図示せず)等の電子部品やプリント基板等から構成され、遊技メダル払出装置12のメダル払出制御や、回転リール装置11の回転制御等を行う。   As shown in FIG. 6, the case main body member 20 includes a main body side case housing 21 formed in a rectangular box shape with an open front surface, and a plate-like engagement formed on the upper side of the main body side case housing 21. And a combined base portion 26. As shown in FIGS. 8 and 9, the case lid member 30 is formed integrally with a lid-side case casing 31 formed in a rectangular box shape with an open rear surface and a right side portion of the lid-side casing casing 31. A rectangular frame portion 35 and a rectangular frame-shaped storage frame portion 37 formed on the upper side of the lid-side case housing 31, and the main control board 16 is attached to the inside of the lid-side case housing 31. In this state, the case body member 20 is closed and attached. At this time, the main control board 16 is accommodated in a case space formed between the main body side case casing 21 and the lid side case casing 31. In addition, a fitting protrusion 36 is formed on the left side surface of the lid-side case housing 31 and protrudes to the left side so as to be fitted to the left side portion of the bracket BR. The main control board 16 includes electronic components such as a ROM (not shown), a printed board, and the like, and performs medal payout control of the game medal payout device 12, rotation control of the rotary reel device 11, and the like.

図6に示すように、ケース本体部材20における本体側ケース筐体21の下側壁外面に所定間隔で三カ所にヒンジアーム22が形成され、上側壁外面に前方に突出する左右一対の係止アーム23が形成されている。図8に示すように、ケース蓋部材30における蓋側ケース筐体31の下側壁内面には、所定間隔で三カ所に上記ヒンジアーム22が揺動自在に係合するヒンジ軸32が形成され、上側壁外面に一対の係止突起33が形成されている。このため、ヒンジ軸32とヒンジアーム22とをヒンジ係合させて、ケース本体部材20に対してケース蓋部材30をこのヒンジ係合部を中心として開閉揺動させることができる。ケース蓋部材30をケース本体部材20の上に重ねて閉止状態とすると、図3に示すように、係止アーム23が係止突起33と係合して閉止状態のまま保持される。   As shown in FIG. 6, a pair of left and right locking arms that have hinge arms 22 formed at three locations at predetermined intervals on the outer surface of the lower side wall of the main body side case 21 in the case main body member 20 and that protrude forward on the outer surface of the upper side wall. 23 is formed. As shown in FIG. 8, on the inner surface of the lower side wall of the lid-side case housing 31 of the case lid member 30, there are formed hinge shafts 32 with which the hinge arms 22 are slidably engaged at three positions at predetermined intervals. A pair of locking projections 33 are formed on the outer surface of the upper side wall. For this reason, the hinge shaft 32 and the hinge arm 22 are hinge-engaged, and the case lid member 30 can be opened and closed with respect to the case body member 20 around the hinge engaging portion. When the case lid member 30 is put on the case body member 20 to be in the closed state, the locking arm 23 is engaged with the locking projection 33 and held in the closed state as shown in FIG.

ケース蓋部材30をケース本体部材20に対し閉止装着させた状態では、係止アーム23がその弾性変形力により係止突起33と係合しているだけである。そのため、係止アーム23を外方に弾性変形させれば係止突起33との係合が解除されて、ケース蓋部材30を簡単に開放できる。そこで、このように閉止状態で取り付けたケース蓋部材30を開放できなくして不正操作を防止するために、ヒンジ係合部と反対側に位置するメイン基板アセンブリMBAの上端部に、不正着脱防止機構DPM1が設けられている。   In a state where the case lid member 30 is closed and attached to the case main body member 20, the locking arm 23 is merely engaged with the locking projection 33 by its elastic deformation force. Therefore, if the locking arm 23 is elastically deformed outward, the engagement with the locking projection 33 is released, and the case lid member 30 can be easily opened. Therefore, in order to prevent the case lid member 30 attached in the closed state from being opened and to prevent unauthorized operation, an unauthorized attachment / detachment prevention mechanism is provided at the upper end portion of the main board assembly MBA located on the side opposite to the hinge engaging portion. DPM1 is provided.

また、不正開放防止機構DPM1により閉止保持された基板ケース15の内部にメイン制御基板16を収容して構成されるメイン基板アセンブリMBAは、本体ケース1の背面板1aに取り付けられたブラケットBRに装着される。メイン基板アセンブリMBAがブラケットBRに装着された状態では、ブラケットBRに形成された上下の保持アーム(図示せず)がその弾性変形力によりメイン基板アセンブリMBAにおける矩形枠部35の上下端部と係合するようになっている。そのため、上下の保持アームを外方に弾性変形させれば矩形枠部35との係合が解除されて、メイン基板アセンブリMBA全体を取り外すことができる。そこで、メイン基板アセンブリMBAを取り外せなくしてその不正交換を防止するために、不正着脱防止機構DPM2がメイン基板アセンブリMBAの右側部に(且つ、矩形枠部35に囲まれる部分に位置して)設けられている。   The main board assembly MBA configured by housing the main control board 16 in the board case 15 closed and held by the unauthorized opening prevention mechanism DPM1 is mounted on the bracket BR attached to the back plate 1a of the main body case 1. Is done. When the main board assembly MBA is mounted on the bracket BR, the upper and lower holding arms (not shown) formed on the bracket BR are engaged with the upper and lower ends of the rectangular frame portion 35 in the main board assembly MBA by the elastic deformation force. It comes to match. Therefore, if the upper and lower holding arms are elastically deformed outward, the engagement with the rectangular frame portion 35 is released, and the entire main board assembly MBA can be removed. Therefore, in order to prevent the main board assembly MBA from being removed and prevent its unauthorized replacement, an unauthorized attachment / detachment prevention mechanism DPM2 is provided on the right side of the main board assembly MBA (and located at a portion surrounded by the rectangular frame portion 35). It has been.

以下に、不正開放防止機構DPM1について説明する。なお、不正着脱防止機構DPM2は、不正開放防止機構DPM1と同様の構成であり、詳細な説明を省略する。不正開放防止機構DPM1は、図4に示すように、ケース本体部材20の係合ベース部26に繋がって形成された本体側係合部50と、ケース蓋部材30の収容枠部37に繋がって形成された蓋側係合部60と、本体側係合部50と蓋側係合部60とに係合される接続部材70とから構成される。   Hereinafter, the unauthorized opening prevention mechanism DPM1 will be described. The unauthorized attachment / detachment prevention mechanism DPM2 has the same configuration as the unauthorized opening prevention mechanism DPM1, and detailed description thereof is omitted.

The lid-side engaging portion 60 is formed, and the connecting member 70 is engaged with the main-body-side engaging portion 50 and the lid-side engaging portion 60.

本体側係合部50は、図11に示すように、前方に開口するとともに本体側底壁52を有した有底円筒状の本体側円筒部51を有して構成され、ケース本体部材20における係合ベース部26の前面側に、左右に8つ並んで形成される。本体側円筒部51内に形成される円筒状の本体側係合空間55内に、互いに対向して(180度離れる位置関係で)本体側係合凹部54,54が形成される。本体側底壁52には、本体側円筒部51の内周面に接するとともに互いに対向して本体側係合空間55内に突出する一対の本体側回転規制突起53,53が形成されている。   As shown in FIG. 11, the main body side engaging portion 50 is configured to have a bottomed cylindrical main body side cylindrical portion 51 that opens forward and has a main body side bottom wall 52. On the front side of the engagement base portion 26, eight are formed side by side. In the cylindrical main body side engaging space 55 formed in the main body side cylindrical portion 51, main body side engaging recesses 54, 54 are formed facing each other (with a positional relationship of 180 degrees apart). The main body side bottom wall 52 is formed with a pair of main body side rotation restricting projections 53, 53 that are in contact with the inner peripheral surface of the main body side cylindrical portion 51 and project into the main body side engaging space 55 opposite to each other.

なお、係合ベース部26は、図7に示すように、後側が格子状に形成されており、メイン基板アセンブリMBAの後方(例えば、ブラケットBRが取り付けられる背面板1aの外方)から不正開放防止機構DPM1に不正にアクセスされるのを防止している。また、図6に示すように、ケース本体部材20においてヒンジアーム22と反対側に位置する係合ベース部26の縁部前面側には、収容枠部37の形状に対応して分割された複数のガイドリブ27が断面半円状に突出して形成されており、図5に示すように、ケース本体部材20に対してケース蓋部材30を閉止させるときに、このガイドリブ27により、係合ベース部26の縁部が滑らかにケース蓋部材30における収容枠部37の縁部内側に導かれるようになっている。なお、本実施形態のメイン基板アセンブリMBAでは、ケース本体部材20に対してケース蓋部材30を滑らかに閉止させるため、ケース本体部材20に対してケース蓋部材30を閉止させるときに、ガイドリブ27の外側半分だけが収容枠部37の縁部内側に当接可能なように各部の寸法公差が設定される。   As shown in FIG. 7, the engagement base portion 26 is formed in a lattice shape on the rear side, and is illegally opened from the rear of the main board assembly MBA (for example, the outside of the back plate 1 a to which the bracket BR is attached). This prevents unauthorized access to the prevention mechanism DPM1. Further, as shown in FIG. 6, the case body member 20 has a plurality of parts divided in accordance with the shape of the housing frame part 37 on the front side of the edge part of the engagement base part 26 located on the opposite side of the hinge arm 22.

Is smoothly guided to the inside of the edge of the housing frame 37 in the case lid member 30. In the main board assembly MBA of the present embodiment, when the case lid member 30 is closed with respect to the case main body member 20 in order to smoothly close the case lid member 30 with respect to the case main body member 20, The dimensional tolerance of each part is set so that only the outer half can contact the inner side of the edge of the housing frame part 37.

蓋側係合部60は、図12に示すように、後方に開口するとともに蓋側底壁62を有した有底円筒状の蓋側円筒部61を有して構成され、ケース蓋部材30の収容枠部37内に、左右に8つ並んで形成される。また、8つの蓋側係合部60はそれぞれ、収容枠部37と上下一対の連結部69を介して繋がれている(図9における円Bで囲まれた部分を参照)。蓋側円筒部61内に形成される円筒状の蓋側係合空間65内に、互いに対向して(180度離れる位置関係で)蓋側係合凹部64,64が形成される。蓋側底壁62には蓋側円筒部61の内周面に接するとともに互いに対向して蓋側係合空間65内に突出する一対の蓋側回転規制突起63,63が形成されている。   As shown in FIG. 12, the lid side engaging portion 60 is configured to have a bottomed cylindrical lid side cylindrical portion 61 that opens rearward and has a lid side bottom wall 62. In the storage frame portion 37, eight are formed side by side. Each of the eight lid-side engaging portions 60 is connected to the housing frame portion 37 via a pair of upper and lower connecting portions 69 (see the portion surrounded by a circle B in FIG. 9). In the cylindrical lid-side engagement space 65 formed in the lid-side cylindrical portion 61, lid-side engagement recesses 64, 64 are formed facing each other (with a positional relationship of 180 degrees apart). The lid-side bottom wall 62 is formed with a pair of lid-side rotation restricting projections 63, 63 that are in contact with the inner peripheral surface of the lid-side cylindrical portion 61 and are opposed to each other and project into the lid-side engagement space 65.

なお、収容枠部37は、図9および図10に示すように、8つの蓋側係合部60を個々に収容可能な枠状に形成されており、図4に示すように、本体側係合部50に対して蓋側係合部60が重なったときに、本体側係合部50および蓋側係合部60がそれぞれ収容枠部37内に収容されるようになっている。これにより、本体側係合部50と蓋側係合部60との境目の部分に異物等が挿入されるのを防止している。また、ケース蓋部材30における蓋側ケース筐体31の右側部(且つ、矩形枠部35に囲まれる部分)には、不正着脱防止機構DPM2を構成する蓋側係合部160が上下に4つ並んで形成されている。この蓋側係合部160も、不正開放防止機構DPM1の蓋側係合部60と同様の構成である。   The housing frame portion 37 is formed in a frame shape capable of individually housing the eight lid side engaging portions 60 as shown in FIGS. 9 and 10, and as shown in FIG. When the lid-side engaging portion 60 overlaps the joint portion 50, the main body-side engaging portion 50 and the lid-side engaging portion 60 are each housed in the housing frame portion 37. Thereby, foreign matter or the like is prevented from being inserted into a boundary portion between the main body side engaging portion 50 and the lid side engaging portion 60. In addition, on the right side portion (and the portion surrounded by the rectangular frame portion 35) of the lid-side case housing 31 in the case lid member 30, four lid-side engaging portions 160 that constitute the unauthorized attachment / detachment prevention mechanism DPM2 are arranged vertically. It is formed side by side. The lid-side engagement portion 160 has the same configuration as the lid-side engagement portion 60 of the unauthorized opening prevention mechanism DPM1.

ところで、図10に示すように、ケース蓋部材30の前面(外面)には、8つの蓋側係合部60(および本体側係合部50)をそれぞれ識別するための第1の識別マーク38aが、収容枠部37の下側に沿って左右に8つ並んで形成されている。第1の識別マーク38aは、ケース蓋部材30の右側から、丸1,丸2,丸3,丸4と2回繰り返して付番されており、本体側係合部50と蓋側係合部60とを2組ずつ係合させるときの順番を識別することができる。また、ケース蓋部材30の前面(外面)には、不正着脱防止機構DPM2を構成する4つの蓋側係合部160をそれぞれ識別するための第2の識別マーク38bが、収容枠部37の右側部に沿って上下に4つ並んで形成されている。   By the way, as shown in FIG. 10, on the front surface (outer surface) of the case lid member 30, first identification marks 38a for identifying the eight lid-side engaging portions 60 (and the main body-side engaging portion 50), respectively. Are formed side by side along the lower side of the storage frame portion 37. The first identification mark 38a is repeatedly numbered twice from the right side of the case lid member 30 as circle 1, circle 2, circle 3, and circle 4, and the main body side engaging portion 50 and the lid side engaging portion are numbered. It is possible to identify the order in which two sets 60 are engaged. Further, on the front surface (outer surface) of the case lid member 30, second identification marks 38 b for identifying the four lid side engaging portions 160 constituting the unauthorized attachment / detachment preventing mechanism DPM 2 are provided on the right side of the housing frame portion 37. Four of them are formed side by side along the part.

一方、図8における円Aで囲まれた部分および図9における円Bで囲まれた部分に示すように、ケース蓋部材30における収容枠部37の後面(縁部)には、「1」が付番された組立用マーク39が2つ形成されている。この組立用マーク39は、ケース蓋部材30の前面において「丸1」の識別マーク38aが付番された蓋側係合部60の裏側部分に形成されており、8組の本体側係合部50および蓋側係合部60のうち、最初に係合させる組(すなわち、ケース蓋部材30の前面において「丸1」の識別マーク38aが付番された)の蓋側係合部60を指し示すことになる。また、組立用マーク39は、収容枠部37の後面(縁部)に形成されるため、図9の二点鎖線で示すように、ケース蓋部材60の内側にメイン制御基板16が取り付けられた状態でも、ケース蓋部材60の内側から視認可能である。   On the other hand, as shown in a portion surrounded by a circle A in FIG. 8 and a portion surrounded by a circle B in FIG. 9, “1” is formed on the rear surface (edge) of the housing frame portion 37 in the case lid member 30. Two numbered assembly marks 39 are formed. The assembly mark 39 is formed on the back side portion of the lid side engaging portion 60 to which the identification mark 38a of “Circle 1” is numbered on the front surface of the case lid member 30, and includes eight sets of body side engaging portions. 50 and the lid-side engaging portion 60, the lid-side engaging portion 60 of the first group to be engaged (that is, the identification mark 38a of “Round 1” is assigned on the front surface of the case lid member 30) is indicated. It will be. Further, since the assembly mark 39 is formed on the rear surface (edge) of the storage frame portion 37, the main control board 16 is attached to the inside of the case lid member 60 as shown by a two-dot chain line in FIG. Even in the state, it is visible from the inside of the case lid member 60.

これにより、メイン基板アセンブリMBAの生産工程において、ケース蓋部材30の内側にメイン制御基板16を取り付けた状態で、最初に係合させる組の蓋側係合部60(および本体側係合部50)を即座に判断して間違うことなく接続部材70を係合させることが可能になり、生産工程における基板ケース15(メイン基板アセンブリMBA)の組立時間を短縮することが可能になる。   Thus, in the production process of the main board assembly MBA, the lid side engaging part 60 (and the main body side engaging part 50) to be engaged first with the main control board 16 attached to the inside of the case lid member 30. ) Can be immediately determined and the connection member 70 can be engaged without making a mistake, and the assembly time of the substrate case 15 (main substrate assembly MBA) in the production process can be shortened.

接続部材70は、図13に示すように、軸方向に貫通する中空円筒の中央に仕切壁を設けた形状の樹脂製接続本体部71を有し、接続本体部71の軸方向一端側に一対の回転規制凹部72が周方向に180度離れて形成され、軸方向他端側に一対の回転規制凹部73が周方向に180度離れて形成されている。接続本体部71にはさらに、一端側近傍において回転規制凹部72と周方向に90度離れる位置関係で一対の係合突起74が形成され、他端側近傍において回転規制凹部73と周方向に90度離れる位置関係で一対の係合突起76が形成されている。   As shown in FIG. 13, the connection member 70 includes a resin connection main body portion 71 having a shape in which a partition wall is provided at the center of a hollow cylinder penetrating in the axial direction. Are formed 180 degrees apart in the circumferential direction, and a pair of rotation regulating recesses 73 are formed 180 degrees apart in the circumferential direction on the other axial end side. The connection main body 71 further has a pair of engaging projections 74 formed in a positional relationship 90 degrees away from the rotation restricting recess 72 in the circumferential direction in the vicinity of one end side, and 90 in the circumferential direction from the rotation restricting recess 73 in the vicinity of the other end side. A pair of engaging protrusions 76 are formed in a positional relationship that is separated by a distance.

これら係合突起74,76は、U字状の切り欠き75a,77aに囲まれて接続本体部71から離れ、基部75b,77bにおいて接続本体部71と繋がり、基部75b,77bを中心とする弾性変形により径方向に揺動可能である。両係合突起74,76はともに、自由状態で接続本体部71の外周面より外方に突出しているが、径方向内方に押されると基部75b,77bを中心として径方向内方に揺動する。   The engagement protrusions 74 and 76 are surrounded by U-shaped cutouts 75a and 77a, are separated from the connection main body 71, are connected to the connection main body 71 at the base portions 75b and 77b, and are elastic around the base portions 75b and 77b. It can swing in the radial direction by deformation. Both the engaging protrusions 74 and 76 protrude outward from the outer peripheral surface of the connection main body 71 in a free state. However, when pressed inward in the radial direction, the engaging protrusions 74 and 76 swing inward in the radial direction around the base portions 75b and 77b. Move.

以上のように構成されたメイン基板アセンブリMBAにおいて、不正開放防止機構DPM1によりケース蓋部材30をケース本体部材20に対し閉止保持させるには、まず、例えばケース蓋部材30の組立用マーク39が指し示す(2つの)蓋側係合部60の蓋側係合空間65内に、それぞれ接続部材70の一端側を挿入する。   In the main board assembly MBA configured as described above, in order to close and hold the case lid member 30 with respect to the case main body member 20 by the unauthorized opening prevention mechanism DPM1, first, for example, the assembly mark 39 of the case lid member 30 indicates. One end side of each connection member 70 is inserted into the lid side engaging space 65 of the (two) lid side engaging portions 60.

このとき、一端側の係合突起74が蓋側係合凹部64と周方向に同一となるように位置合わせして接続部材70を蓋側係合空間65内に挿入する。また、このように蓋側係合凹部64内に係合突起74が入り込むように位置合わせすることにより、蓋側回転規制突起63が回転規制凹部72内に入り込む。逆に言えば、この位置合わせ方向と異なる回転方向位置で接続部材70を挿入しようとしても蓋側回転規制突起63が邪魔して挿入ができないような構成となっている。これにより、蓋側円筒部61の側壁部に当接した係合突起74が内方に押されて弾性変形した後、蓋側係合凹部64内に入り込んで元の形状となって係合し、一端側が挿入された状態で接続部材70が蓋側係合部60に係合保持される。なお、この作業は係合突起74を内方に弾性変形させる程度の押し込み力を加えるだけであり、工具を用いることなく手作業で簡単に行える。   At this time, the connection member 70 is inserted into the lid-side engagement space 65 by aligning the engagement protrusion 74 on one end side with the lid-side engagement recess 64 in the circumferential direction. In addition, the lid side rotation restricting protrusion 63 enters the rotation restricting recess 72 by positioning so that the engaging protrusion 74 enters the cover side engaging recess 64 in this way. In other words, the lid side rotation restricting projection 63 interferes with the insertion of the connection member 70 at a rotational direction position different from the alignment direction, and the insertion cannot be performed. As a result, the engaging protrusion 74 that is in contact with the side wall portion of the lid-side cylindrical portion 61 is pushed inward and elastically deformed, and then enters the lid-side engaging recess 64 to engage with the original shape. The connection member 70 is engaged and held by the lid side engaging portion 60 in a state where the one end side is inserted. Note that this operation only requires a pressing force to elastically deform the engagement protrusion 74 inward, and can be easily performed manually without using a tool.

次に、ケース蓋部材30を揺動させてケース本体部材20に対し閉止装着させる。このとき、図5に示すように、ガイドリブ27により、ケース本体部材20における係合ベース部26の縁部が滑らかにケース蓋部材30における収容枠部37の縁部内側に導かれる。さらにこのとき、ケース本体部材20の本体側ケース筐体21における左右および下側の縁部(側壁部)も、ケース蓋部材30の蓋側ケース筐体31における左右および下側の縁部(側壁部)の内側に位置する。   Next, the case lid member 30 is rocked and attached to the case body member 20 in a closed manner. At this time, as shown in FIG. 5, the edge of the engagement base portion 26 in the case main body member 20 is smoothly guided to the inside of the edge portion of the housing frame portion 37 in the case lid member 30 by the guide rib 27. Further, at this time, the left and right and lower edges (side walls) of the main body side case casing 21 of the case main body member 20 are also the left and right and lower edges (side walls) of the lid side case casing 31 of the case lid member 30. Part).

また、ケース本体部材20に対してケース蓋部材30を閉止装着させると、図4に示すように、蓋側係合部60が本体側係合部50と重なるとともに、蓋側係合部60に係合保持されて突出する接続部材70の他端側が本体側係合部50の本体側係合空間55内に挿入される。これにより、本体側円筒部51の側壁部に当接した係合突起76が内方に押されて弾性変形した後、本体側係合凹部54内に入り込んで元の形状となって係合し、他端側が挿入された状態で接続部材70が本体側係合部50とも係合保持される。このとき、接続部材70は蓋側係合部60に対して蓋側係合凹部64内に係合突起74が入り込むとともに蓋側回転規制突起63が回転規制凹部72内に入り込んで位置決めされており、この状態でケース蓋部材30が閉止されると本体側回転規制突起53が回転規制凹部73内に入り込む。なお、この作業もケース蓋部材30を手で押してケース本体部材20の上に閉止するだけでよく、手作業で簡単に行える。   Further, when the case lid member 30 is attached to the case body member 20 in a closed manner, as shown in FIG. 4, the lid side engaging portion 60 overlaps the main body side engaging portion 50 and the lid side engaging portion 60 The other end side of the connecting member 70 that is engaged and held and protrudes is inserted into the main body side engaging space 55 of the main body side engaging portion 50. As a result, the engaging protrusion 76 that contacts the side wall portion of the main body side cylindrical portion 51 is pushed inward and elastically deformed, and then enters the main body side engaging recess 54 to be engaged in the original shape. The connecting member 70 is also engaged and held with the main body side engaging portion 50 in a state where the other end side is inserted. At this time, the connection member 70 is positioned with respect to the lid-side engagement portion 60 so that the engagement protrusion 74 enters the lid-side engagement recess 64 and the lid-side rotation restriction projection 63 enters the rotation restriction recess 72. When the case lid member 30 is closed in this state, the main body side rotation restricting protrusion 53 enters the rotation restricting recess 73. In addition, this operation | work only needs to push the case cover member 30 by hand and it closes on the case main body member 20, and can be easily performed manually.

この結果、接続部材70の係合突起74が蓋側係合凹部64内に突出して接続部材70の一端側が蓋側係合部60と係合し、係合突起76が本体側係合凹部54内に突出して接続部材70の他端側が本体側係合部50と係合し、ケース本体部材20にケース蓋部材30が閉止状態で保持され、これを外部から外すことができない状態となる。このため、ケース蓋部材30を開放してケース内に配設されたメイン制御基板16に対する不正アクセス、例えば、メイン制御基板16に取り付けられたROM(図示せず)に対する不正アクセスを確実に防止できる。   As a result, the engagement protrusion 74 of the connection member 70 protrudes into the lid-side engagement recess 64, one end side of the connection member 70 engages with the lid-side engagement portion 60, and the engagement protrusion 76 becomes the main body-side engagement recess 54. The other end side of the connecting member 70 is engaged with the main body side engaging portion 50, and the case lid member 30 is held in the closed state by the case main body member 20 and cannot be removed from the outside. For this reason, it is possible to reliably prevent unauthorized access to the main control board 16 disposed in the case with the case lid member 30 opened, for example, unauthorized access to a ROM (not shown) attached to the main control board 16. .

なお、接続部材70の挿入は上記と逆でも良い。すなわち、接続部材70の他端側を装着側係合空間65内に挿入して係合突起76を蓋側係合凹部64と係合させ、蓋側係合部60が本体側係合部50と重なるときに接続部材70の一端側を本体側係合空間55内に挿入させ、係合突起74を本体側係合凹部54と係合させても良い。このため、接続部材70は軸方向に対称形状に作られている。また、接続部材70の挿入順序は上記と逆でも良い。すなわち、接続部材70の一端側(もしくは他端側)を本体側係合部50と係合させてから、ケース蓋部材30を閉止させて接続部材70の他端側(もしくは一端側)を蓋側係合部60と係合させるようにしても良い。   Note that the insertion of the connecting member 70 may be reversed. That is, the other end side of the connecting member 70 is inserted into the mounting side engaging space 65 to engage the engaging protrusion 76 with the lid side engaging recess 64, and the lid side engaging portion 60 is connected to the main body side engaging portion 50. One end side of the connection member 70 may be inserted into the main body side engaging space 55 and the engaging protrusion 74 may be engaged with the main body side engaging concave portion 54 when overlapping. For this reason, the connection member 70 is made symmetrical in the axial direction. Further, the insertion order of the connection member 70 may be reversed. That is, after one end side (or the other end side) of the connection member 70 is engaged with the main body side engaging portion 50, the case lid member 30 is closed and the other end side (or one end side) of the connection member 70 is closed. You may make it engage with the side engaging part 60. FIG.

なお、以上のようにしてケース本体部材20に対しケース蓋部材30を閉止装着させて、不正開放防止機構DPM1により閉止保持されたメイン基板アセンブリMBAは、前述したようにブラケットBRに取り付けられ、不正着脱防止機構DPM2により係合保持されるが、この作動は上述した不正開放防止機構DPM1と同様に行われる。   As described above, the main board assembly MBA, which is closed by the case lid member 30 with respect to the case body member 20 and held by the unauthorized opening prevention mechanism DPM1, is attached to the bracket BR as described above. Although engaged and held by the detachment prevention mechanism DPM2, this operation is performed in the same manner as the unauthorized opening prevention mechanism DPM1 described above.

続いて、以上のようにして不正開放防止機構DPM1により閉止保持されたメイン基板アセンブリMBAについて、その内部のメイン基板16の保守点検作業を行う場合について説明する。保守点検作業を行うときには、例えばニッパ等の工具を用いて接続部材70と係合された組(例えば、ケース蓋部材30の前面において「丸1」の識別マーク38aが付番された組)の蓋側係合部60における収容枠部37との連結部69をそれぞれ切断する。これにより、蓋側係合部60とケース蓋部材30とが切り離されて不正開放防止機構DPM1による係合保持が解かれるので、ケース蓋部材30を開放することができ、ケース蓋部材30の内側に取り付けられたメイン制御基板16の保守点検等を行うことができる。   Next, a case will be described in which maintenance inspection work is performed on the main board 16 inside the main board assembly MBA held closed by the unauthorized opening prevention mechanism DPM1 as described above. When performing maintenance and inspection work, for example, a set engaged with the connection member 70 by using a tool such as a nipper (for example, a set in which the identification mark 38a of “circle 1” is numbered on the front surface of the case lid member 30) is used. The connection part 69 with the accommodating frame part 37 in the lid side engaging part 60 is cut off. As a result, the lid-side engaging portion 60 and the case lid member 30 are separated and the engagement and holding by the unauthorized opening prevention mechanism DPM1 is released, so that the case lid member 30 can be opened, and the inside of the case lid member 30 Maintenance inspection of the main control board 16 attached to can be performed.

前述のように、本体側係合部50および蓋側係合部60は左右に8つ並んで設けられているが、例えば8組の本体側係合部50および蓋側係合部60のうちいずれか2組(より具体的には、ケース蓋部材30の前面において同じ番号の識別マーク38aが付番された組)のみに接続部材70を用いて、ケース本体部材20に対しケース蓋部材30を閉止状態で保持している。そして、保守点検作業に際しては、このように接続部材70を用いて係合された組の蓋側係合部60における連結部69のみが切断される。   As described above, eight main body side engaging portions 50 and eight lid side engaging portions 60 are provided side by side. For example, of the eight sets of main body side engaging portions 50 and lid side engaging portions 60. The case lid member 30 is connected to the case body member 20 by using the connection member 70 only in any two sets (more specifically, a set numbered with the identification mark 38a having the same number on the front surface of the case lid member 30). Is held closed. In the maintenance and inspection work, only the connecting portion 69 in the lid side engaging portion 60 of the set engaged using the connecting member 70 is cut.

以上のようにして蓋側係合部60を開放して制御基板16の保守点検が完了した後は、未使用の本体側係合部50および蓋側係合部60のうちいずれか2組(例えば、ケース蓋部材30の前面において「丸2」以降のいずれか同じ番号の識別マーク38aが付番された組)に接続部材70を用いて、ケース本体部材20に対しケース蓋部材30を閉止状態で保持する。このため、本実施形態のメイン基板アセンブリMBAの場合には、途中において3度の保守点検が可能である。   After the lid side engaging part 60 is opened as described above and the maintenance inspection of the control board 16 is completed, any two sets of the unused main body side engaging part 50 and the lid side engaging part 60 ( For example, the case lid member 30 is closed with respect to the case body member 20 by using the connection member 70 in the front face of the case lid member 30 with the identification mark 38a having the same number after “Round 2”. Hold in state. For this reason, in the case of the main board assembly MBA of the present embodiment, three maintenance inspections are possible in the middle.

そして、本実施形態によれば、ケース本体部材20においてヒンジ機構(ヒンジアーム22)が設けられる側と反対側にする係合ベース部26の縁部に、ガイドリブ27が突出して形成されており、このガイドリブ27によって、ケース本体部材20に対しケース蓋部材30を閉止させるときに、ガイドリブ27が形成された係合ベース部26の縁部がケース蓋部材30における収容枠部37の縁部内側に導かれるため、ケース本体部材20とケース蓋部材30との隙間が小さくても、ケース本体部材20に対してケース蓋部材30を滑らかに閉止させることが可能になる。なお、ガイドリブ27が突出して形成されるため、例えば収容枠部37の縁部内側にテーパ等のガイドを形成する場合と比べて、ケース本体部材20(係合ベース部26の縁部)とケース蓋部材30(収容枠部37の縁部)との隙間を小さくすることが可能になる。   And according to this embodiment, the guide rib 27 protrudes and is formed in the edge part of the engagement base part 26 made into the opposite side to the side in which the hinge mechanism (hinge arm 22) is provided in the case main body member 20, When the case lid member 30 is closed with respect to the case body member 20 by the guide rib 27, the edge of the engagement base portion 26 on which the guide rib 27 is formed is located inside the edge of the housing frame portion 37 in the case lid member 30. Therefore, even when the gap between the case body member 20 and the case lid member 30 is small, the case lid member 30 can be smoothly closed with respect to the case body member 20. Since the guide rib 27 is formed so as to protrude, the case main body member 20 (the edge of the engagement base portion 26) and the case are compared with the case where a guide such as a taper is formed inside the edge of the housing frame 37, for example. It is possible to reduce the gap with the lid member 30 (the edge of the storage frame portion 37).

また、メイン基板アセンブリMBA(基板ケース15)におけるヒンジ機構(ヒンジアーム22およびヒンジ軸32)が設けられる側と反対側の端部近傍に、不正開放防止機構DPM1が設けられることで、ケース本体部材20に対してケース蓋部材30を滑らかに閉止させると同時に、不正開放防止機構DPM1によるメイン基板アセンブリMBAの閉止保持動作を滑らかに行うことが可能になる。   In addition, in the main board assembly MBA (board case 15), the unauthorized opening prevention mechanism DPM1 is provided in the vicinity of the end opposite to the side where the hinge mechanism (the hinge arm 22 and the hinge shaft 32) is provided, so that the case body member The case lid member 30 can be smoothly closed with respect to 20, and at the same time, the closing holding operation of the main board assembly MBA by the unauthorized opening prevention mechanism DPM1 can be smoothly performed.

なお、上述の実施形態において、スロットマシンの本体ケース内に取り付けられた基板ケース(メイン基板アセンブリ)を例にして説明したが、本発明の基板ケースはこれに限られるものではない。例えば、スロットマシンの他の部分(カバーの裏面等)に設けられた基板ケース(いわゆる、サブ基板アセンブリ)についても同様な構成を適用でき、また、雀球遊技機やパチンコ機等といった遊技機の内部に配設される基板ケースにも適用することができる。   In the above-described embodiment, the substrate case (main substrate assembly) attached in the main body case of the slot machine has been described as an example. However, the substrate case of the present invention is not limited to this. For example, the same configuration can be applied to a board case (so-called sub-board assembly) provided in another part of the slot machine (back surface of the cover, etc.), and a game machine such as a sparrow ball machine or a pachinko machine The present invention can also be applied to a substrate case disposed inside.

また、上述の実施形態において、8組の本体側係合部50および蓋側係合部60のうちいずれか2組のみに接続部材70を用いて、ケース本体部材20に対しケース蓋部材30を閉止状態で保持しているが、これに限られるものではなく、例えば1組だけ係合させるようにしてもよく、所望の組数だけ係合させることが可能である。さらに、不正開放防止機構DPM1は、接続部材70を用いて本体側係合部50と蓋側係合部60とを係合させる構成に限らず、例えば、いわゆる「一方向ネジ」を用いて、ケース本体部材とケース蓋部材とを締結させるような構成であっても構わない。   Further, in the above-described embodiment, the case lid member 30 is attached to the case body member 20 by using the connection member 70 only in any two of the eight sets of the body side engaging portion 50 and the lid side engaging portion 60.
