Description

本発明は、ＣＰＵやＲＯＭ等の制御素子を備えた制御基板を収容するための制御基板ケースに関し、詳細には、遊技機用の制御基板を収容する遊技機の制御基板ケースに関する。 The present invention relates to a control board case for housing a control board having control elements such as a CPU and a ROM, and more particularly to a control board case for a gaming machine that houses a control board for a gaming machine.

従来より、パチンコ機やスロットマシン等の遊技機では、遊技機の動作を制御するためのＣＰＵやＲＯＭ等の制御素子を備えた制御基板が、合成樹脂製の制御基板ケースの内部に収容されている。これは、制御基板ケースによって制御基板を保護するとともに、ＲＯＭを交換して遊技内容を恣意的に変更しようとする不正行為を防ぐためである。そして、この制御基板ケースについて、不正なＲＯＭ交換を目的としたカバーのこじ開けをより確実に防止するために、さまざまな公知技術が知られている。 Conventionally, in gaming machines such as pachinko machines and slot machines, a control board having control elements such as a CPU and a ROM for controlling the operation of the gaming machine is housed inside a control board case made of synthetic resin. Yes. This is to protect the control board by the control board case and to prevent an illegal act of arbitrarily changing the game contents by exchanging the ROM. Various known techniques are known for this control board case in order to more reliably prevent the cover from being opened for the purpose of illegal ROM replacement.

例えば、ベース部材とカバー部材とで箱形の制御基板ケースを形成する場合に、カバー部材の側壁から先端を屈曲した係止片を延設させるとともに、ベース部材の側壁には同屈曲部分が貫通して係止可能なスリットを形成し、ベース部材とカバー部材とを合体させるときに係止片の先端が外側からスリットを通過して係止することにより、こじ開けようとしても係止構造が引き離し方向へのこじ開けに抗するように作用するものが知られている（例えば、特許文献１を参照。）。 For example, when a box-shaped control board case is formed of a base member and a cover member, a locking piece having a bent end is extended from the side wall of the cover member, and the bent portion penetrates the side wall of the base member. Thus, when the base member and the cover member are united, the tip of the locking piece passes through the slit from the outside and locks, so that the locking structure can be pulled apart even if you try to pry it open. There is known a device that acts to resist prying in a direction (see, for example, Patent Document 1).

また、ボックスカバーがボックスベースの開放部分に覆設されて形成される制御基板ケースにおいて、ボックスベースの嵌挿凸部がボックスカバーの嵌挿凹部に嵌挿されるようにして、ボックスベース及びボックスカバーの合わせ目に薄板状の工具等を差し込み、基板ボックスをこじ開けようとしても、薄板状の工具等の先端部分が嵌挿凸部に突き当たり、その差し込みを防止することができるものが知られている（例えば、特許文献２を参照。）。 Further, in the control board case formed by covering the box cover with the open portion of the box base, the box base and the box cover are arranged so that the fitting insertion convex portion of the box base is inserted into the fitting concave portion of the box cover. It is known that even if a thin plate-like tool or the like is inserted into the joint and the board box is to be opened, the tip portion of the thin plate-like tool or the like hits the fitting insertion convex portion to prevent the insertion. (For example, see Patent Document 2).

また、制御基板ケースの本体に、ヒンジ機構により枢結された一側縁を構成する側板部に係合孔を設ける一方、蓋体の裏面に本体の係合孔に嵌挿される係止片を設けて、蓋体が閉止されると本体の側板部の係合孔に蓋体の係止片が嵌挿されることで、蓋体が上動不能に位置規制されて変形させることができないものが知られている（例えば、特許文献３を参照。）。

When the lid body is closed, the lid body is inserted into the engagement hole of the side plate portion of the main body so that the lid body cannot be moved and cannot be deformed. It is known (for example, refer to Patent Document 3).

The caulking screws 80a to 80d (caulking screws 90a to 90d) are one-way type screws having a head that can be screwed only in the tightening direction, and have a large-diameter portion with a large diameter at the tip of the body portion. is doing. And the caulking screw 80a-80d (caulking screw 90a-90d) is penetrated by the through-hole of the bases 21a-21d (base 22a-22d), and screw receiving part 31a-31d (screw receiving part 32a-32d). The cover member 20 is tightly fixed to the base member 30 by being fitted into the screw hole and the large-diameter portion is locked in the screw hole, which will be described in detail later.

以上のような構成において、カバー部材２０の開口面とベース部材３０の開口面とは同一形状をなし、これらの開口面を対向させつつ、その縁部を合致させるように両者を密着させることで、カバー部材２０とベース部材３０とが接触する四方縁部において両者が固定されて制御基板ケース１０が構成される。 In the configuration as described above, the opening surface of the cover member 20 and the opening surface of the base member 30 have the same shape, and these opening surfaces are opposed to each other so that the edges are brought into close contact with each other. The control board case 10 is configured by fixing the cover member 20 and the base member 30 at the four side edges where they are in contact with each other.

次に、制御基板ケース１０における上記固定部位を個別に説明する。図４は、制御基板ケース１０の正面図である。図５は、右かしめ部１１ａ〜１１ｄの斜視断面図である。図６は、右かしめ部１１ａの部分拡大図である。図７は、係合部１４の部分断面図である。 Next, the fixed part in the control board case 10 will be described individually. FIG. 4 is a front view of the control board case 10. FIG. 5 is a perspective cross-sectional view of the right caulking portions 11a to 11d. FIG. 6 is a partially enlarged view of the right caulking portion 11a. FIG. 7 is a partial cross-sectional view of the engaging portion 14.

図４に示すように、制御基板ケース１０の右側面６１では、台座２１ａ〜２１ｄとネジ受け部３１ａ〜３１ｄとが各々係合されて、かしめネジ８０ａ〜８０ｄが嵌着される右かしめ部１１ａ〜１１ｄが形成される。同様に、制御基板ケース１０の左側面６２では、台座２２ａ〜２２ｄとネジ受け部３２ａ〜３２ｄとが各々係合されて、かしめネジ９０ａ〜９０ｄが嵌着される左かしめ部１２ａ〜１２ｄが形成される。なお、右かしめ部１１ａ〜１１ｄの４箇所全てを用いる必要はなく、うちの１箇所にかしめネジ８０ａ〜８０ｄの１つを嵌着すればよく、同様に、左かしめ部１２ａ〜１２ｄの４箇所全てを用いる必要はなく、うちの１箇所にかしめネジ９０ａ〜９０ｄの１つを嵌着すればよい。以下では、番号「１」が付された右かしめ部１１ａ及び左かしめ部１２ａを用いて固定する場合を例示する。 As shown in FIG. 4, on the right side surface 61 of the control board case 10, the pedestals 21a to 21d and the screw receiving portions 31a to 31d are respectively engaged, and the right caulking portion 11a to which the caulking screws 80a to 80d are fitted. To 11d are formed. Similarly, on the left side surface 62 of the control board case 10, the bases 22a to 22d and the screw receiving portions 32a to 32d are engaged with each other, and left caulking portions 12a to 12d to which the caulking screws 90a to 90d are fitted are formed. Is done. Note that it is not necessary to use all four places of the right caulking portions 11a to 11d, and it is only necessary to fit one of the caulking screws 80a to 80d to one of them, and similarly, four places of the left caulking portions 12a to 12d. It is not necessary to use all of them, and one of the caulking screws 90a to 90d may be fitted into one of them. Below, the case where it fixes using the right caulking part 11a and the left caulking part 12a which were attached | subjected the number "1" is illustrated.

図５及び図６に示すように、右かしめ部１１ａにおいて、台座２１ａはかしめネジ８０ａが貫挿される円柱状中空を有する筒状体２１０と、筒状体２１０を支持してカバー部材２０に連結する連結部材２１１，２１２と、筒状体２１０の内部に設けられてかしめネジ８０ａの径の大きさに応じて伸縮してかしめネジ８０ａを固定する係止羽根２１３，２１４を備えている。また、筒状体２１０はネジ受け部３１のネジ孔に連通される。なお、右かしめ部１１ｂ〜１１ｄの構成も右かしめ部１１ａと同様であり、４つの筒状体が並列に設けられるとともに、台座２１ａ〜２１ｄはカバー部材２０に一体に設けられている。また、左かしめ部１２ａ〜１２ｄの構成も右かしめ部１１ａ〜１１ｄと同様である。 As shown in FIGS. 5 and 6, in the right caulking portion 11a, the base 21a is connected to the cover member 20 by supporting the cylindrical body 210 with a cylindrical hollow body 210 through which the caulking screw 80a is inserted. Connecting members 211 and 212 to be connected, and locking blades 213 and 214 provided inside the cylindrical body 210 to expand and contract in accordance with the diameter of the caulking screw 80a to fix the caulking screw 80a. The cylindrical body 210 is communicated with the screw hole of the screw receiving portion 31. The right caulking portions 11b to 11d are configured in the same manner as the right caulking portion 11a, and four cylindrical bodies are provided in parallel, and the bases 21a to 21d are provided integrally with the cover member 20. The configurations of the left caulking portions 12a to 12d are the same as those of the right caulking portions 11a to 11d.

そして、制御基板ケース１０を形成する場合、かしめネジ８０ａを筒状体２１０に挿入しその頭部を回動押圧して、かしめネジ８０ａの頭部が係止羽根２１３，２１４に当接するまで押し込む。すると、かしめネジ８０ａの胴部がその側面から係止羽根２１３，２１４により押圧されて固定され、胴部の先端に設けられた大口径部がネジ受け部３１のネジ孔に嵌挿される。そして、かしめネジ８０ａはワンウェイタイプのネジであるから、かしめネジ８０ａは引き抜くことが不可能である（図５参照）。同様に、左かしめ部１２ａにもかしめネジ９０ａが嵌め込まれる。 When forming the control board case 10, the caulking screw 80 a is inserted into the cylindrical body 210, and the head is rotated and pressed until the head of the caulking screw 80 a contacts the locking blades 213 and 214. . Then, the barrel portion of the caulking screw 80 a is pressed and fixed from the side by the locking blades 213 and 214, and the large diameter portion provided at the tip of the barrel portion is inserted into the screw hole of the screw receiving portion 31. Since the caulking screw 80a is a one-way type screw, the caulking screw 80a cannot be pulled out (see FIG. 5). Similarly, a caulking screw 90a is fitted into the left caulking portion 12a.

一方、内部の制御基板の検査や修理などの理由で、制御基板ケース１０を開放する必要となった場合、ニッパーやカッター等で連結部材２１１，２１２を切断すれば筒状体２１０を取り外すことができるため、右かしめ部１１ａ及びかしめネジ８０ａを破棄することができる（図６参照）。同様に左かしめ部１２ａ及びかしめネジ９０ａも破棄すれば、制御基板ケース１０を開放することができる。そして、再度制御基板ケース１０を閉じる場合には、他の右かしめ部１１ｂ〜１１ｄ及び左かしめ部１２ｂ〜１２ｄに、かしめネジ８０ｂ〜８０ｄ及びかしめネジ９０ｂ〜９０ｄを嵌着すればよい。 On the other hand, when it is necessary to open the control board case 10 for reasons such as inspection or repair of the internal control board, the cylindrical body 210 can be removed by cutting the connecting members 211 and 212 with a nipper or a cutter. Therefore, the right caulking portion 11a and the caulking screw 80a can be discarded (see FIG. 6). Similarly, if the left caulking portion 12a and the caulking screw 90a are also discarded, the control board case 10 can be opened. When the control board case 10 is closed again, the caulking screws 80b to 80d and the caulking screws 90b to 90d may be fitted to the other right caulking portions 11b to 11d and the left caulking portions 12b to 12d.

また、図４及び図５に示すように、制御基板ケース１０の右側面６１では、右かしめ部１１ａの下側において、爪受け部２８ａに形成された貫通孔に係止爪部３８ａが挿入され、係止爪部３８ａの先端に形成された爪部が爪受け部２８ａに係止されて、係合部１８ａが形成される。同様に右かしめ部１１ｄの上側において、係止爪部３８ｂが爪受け部２８ｂに係止されて、係合部１８ｂが形成される。なお、制御基板ケース１０の左側面６２でも、係止爪部３９ａ，３９ｂが爪受け部２９ａ，２９ｂに各々係止されて、係合部１９ａ，１９ｂが形成される。 Further, as shown in FIGS. 4 and 5, in the right side surface 61 of the control board case 10, the locking claw portion 38a is inserted into the through hole formed in the claw receiving portion 28a below the right caulking portion 11a. The claw portion formed at the tip of the locking claw portion 38a is locked to the claw receiving portion 28a to form the engaging portion 18a. Similarly, on the upper side of the right caulking portion 11d, the engaging claw portion 38b is engaged with the claw receiving portion 28b to form the engaging portion 18b. Note that, also on the left side surface 62 of the control board case 10, the engaging claw portions 39a and 39b are engaged with the claw receiving portions 29a and 29b to form the engaging portions 19a and 19b.

次に、図４及び図７に示すように、制御基板ケース１０の下側面６３では、カバー部材２０の下端部において若干隆起するように形成された爪受け部２４に、ベース部材３０の下端部に設けられた係止爪部３４の先端の爪片が係止されて、係合部１４が形成される。 Next, as shown in FIGS. 4 and 7, on the lower surface 63 of the control board case 10, the lower end portion of the base member 30 is placed on the claw receiving portion 24 formed so as to slightly protrude at the lower end portion of the cover member 20. The claw piece at the tip of the locking claw portion 34 provided on the locking portion is locked to form the engaging portion 14.

以上のように、制御基板ケース１０は、右側面６１が係合部１８ａ，１８ｂと右かしめ部１１ａ〜１１ｄにより固定され、左側面６２が係合部１９ａ，１９ｂと左かしめ部１２ａ〜１２ｄにより固定される。このように、対向する二側面で固定された制御基板ケース１０は、通常は開放できない構成となっている。さらに、下側面６３も係合部１４により固定されるため、制御基板ケース１０はより強固に固定される。しかし、上側面６４からこじ開けようとする不正行為を簡易な構成で確実に防止するために、嵌挿凹部２３ａ，２３ｂと嵌挿凸部３３ａ，３３ｂとが各々係合された嵌挿部１３ａ，１３ｂを設けている。 As described above, in the control board case 10, the right side surface 61 is fixed by the engaging portions 18a and 18b and the right caulking portions 11a to 11d, and the left side surface 62 is fixed by the engaging portions 19a and 19b and the left caulking portions 12a to 12d. Fixed. As described above, the control board case 10 fixed on the two opposite sides is normally configured not to be opened. Furthermore, since the lower surface 63 is also fixed by the engaging part 14, the control board case 10 is fixed more firmly. However, in order to reliably prevent an illegal act of opening from the upper side surface 64 with a simple configuration, the fitting insertion portions 13a, 23a, 33b and the fitting insertion portions 13a, 33b are engaged with each other. 13b is provided.

次に、嵌挿部１３ａ，１３ｂについて説明する。なお、以下では嵌挿部１３ａについて説明するが、嵌挿部１３ｂも同じである。図８は、カバー部材２０及びベース部材３０の拡大平面図である。図９は、カバー部材２０及びベース部材３０のＡ−Ａ´線（図８）における矢視方向断面図である。図１０は、嵌挿部１３ａのＡ−Ａ´線（図８）における矢視方向断面図である。図１１は、制御基板ケース１０の拡大背面図である。 Next, the insertion parts 13a and 13b will be described. In addition, although the insertion part 13a is demonstrated below, the insertion part 13b is also the same. FIG. 8 is an enlarged plan view of the cover member 20 and the base member 30. FIG. 9 is a cross-sectional view in the arrow direction of the cover member 20 and the base member 30 along the line AA ′ (FIG. 8). FIG. 10 is a cross-sectional view in the direction of the arrow in the AA ′ line (FIG. 8) of the insertion portion 13a. FIG. 11 is an enlarged rear view of the control board case 10.

図８及び図９に示すように、カバー部材２０に設けられた嵌挿凹部２３ａには、開口面側からコの字形状に凹陥された凹陥部２３１が形成され、カバー部材２０の上側面４４の長手方向（図８の上下方向）における凹陥部２３１の両側は、カバー部材２０の上側面４４の厚みよりも薄く段差状に形成された係合板２３２，２３３が設けられている。一方、ベース部材３０に設けられた嵌挿凸部３３ａは、カバー部材２０の上側面４４（ベース部材３０の上側面５４）と平行をなす板状の部材である封止板３３２と、ベース部材３０の上側面５４から突出して封止板３３２を支持するコの字型の支持部材３３１とから構成されており、正面視、嵌挿凸部３３ａは封止板３３２が支持部材３３１の上端部の両側面から突出したようなＴ字型形状の外観をなす。 As shown in FIG. 8 and FIG. 9, the fitting insertion recess 23 a provided in the cover member 20 is formed with a recess 231 that is recessed in a U shape from the opening surface side, and the upper side surface 44 of the cover member 20. On both sides of the recessed portion 231 in the longitudinal direction (vertical direction in FIG. 8), engagement plates 232 and 233 are formed which are formed in a stepped shape that is thinner than the thickness of the upper side surface 44 of the cover member 20. On the other hand, the insertion insertion convex part 33a provided in the base member 30 includes a sealing plate 332 that is a plate-like member parallel to the upper side surface 44 of the cover member 20 (the upper side surface 54 of the base member 30), and the base member. 30 and a U-shaped support member 331 that protrudes from the upper side surface 54 and supports the sealing plate 332. When viewed from the front, the insertion protrusion 33 a is the upper end of the support member 331. Appearance of a T-shaped shape that protrudes from both side surfaces.

また、平面視、封止板３３２の形状及び大きさは、嵌挿凹部２３ａ（凹陥部２３１と係合板２３２，２３３とを含めた範囲）の形状及び大きさと略同一である。また、支持部材３３１により形成されるコの字型の断面形状は、平面視、凹陥部２３１に収容可能な形状及び大きさである。そして、ベース部材３０の上側面５４において、支持部材３３１と封止板３３２とで画される空間が係止部３３３，３３４である。係止部３３３は係合板２３２と同一の形状及び大きさをなし、係止部３３３に係合板２３２が嵌挿される。同様に、係止部３３４は係合板２３３と同一の形状及び大きさをなし、係止部３３４に係合板２３３が嵌挿される（図８参照）。 Further, in plan view, the shape and size of the sealing plate 332 are substantially the same as the shape and size of the fitting insertion recess 23a (a range including the recessed portion 231 and the engagement plates 232 and 233). The U-shaped cross-sectional shape formed by the support member 331 has a shape and size that can be accommodated in the recessed portion 231 in a plan view. Further, on the upper side surface 54 of the base member 30, spaces defined by the support member 331 and the sealing plate 332 are locking portions 333 and 334. The engaging portion 333 has the same shape and size as the engaging plate 232, and the engaging plate 232 is inserted into the engaging portion 333. Similarly, the engaging portion 334 has the same shape and size as the engaging plate 233, and the engaging plate 233 is inserted into the engaging portion 334 (see FIG. 8).

また、正面視（側面視）、係合板２３２，２３３の厚みは、ベース部材３０の上側面５４から封止板３３２までの高さ（支持部材３３１の高さ）と略同一である。そして、係合板２３２，２３３の厚みと封止板３３２の厚みとを足すと、カバー部材２０の上側面４４の厚みと略均等となる。言い換えれば、支持部材３３１の下端部（ベース部材３０の上側面５４）から封止板３３２の上端面までの高さと、カバー部材２０の上側面４４の厚みと略均等となる（図９参照）。 Further, the thickness of the engagement plates 232 and 233 in front view (side view) is substantially the same as the height from the upper side surface 54 of the base member 30 to the sealing plate 332 (height of the support member 331). When the thicknesses of the engagement plates 232 and 233 and the thickness of the sealing plate 332 are added, the thickness of the upper side surface 44 of the cover member 20 is substantially equal. In other words, the height from the lower end portion of the support member 331 (the upper side surface 54 of the base member 30) to the upper end surface of the sealing plate 332 and the thickness of the upper side surface 44 of the cover member 20 are substantially equal (see FIG. 9). .

そして、カバー部材２０をベース部材３０に固定して制御基板ケース１０を形成する場合は、カバー部材２０の開口面とベース部材３０の開口面とが平行面をなすように対向させ、かつ、カバー部材２０の上側面４４とベース部材３０の上側面５４が平行面をなすようにして、両開口面の縁部を合致させるように組み合わせると、嵌挿凹部２３ａと嵌挿凸部３３ａとが係合される（図８及び図９参照）。 When the control board case 10 is formed by fixing the cover member 20 to the base member 30, the opening surface of the cover member 20 and the opening surface of the base member 30 face each other so as to form a parallel surface, and the cover When the upper side surface 44 of the member 20 and the upper side surface 54 of the base member 30 form a parallel surface and are combined so that the edges of the two opening surfaces coincide with each other, the insertion concave portion 23a and the insertion convex portion 33a are engaged. (See FIGS. 8 and 9).

すると、図１０及び図１１に示すように、制御基板ケース１０では、嵌挿凹部２３ａ（嵌挿凹部２３ｂ）と嵌挿凸部３３ａ（嵌挿凸部３３ｂ）とが係合されると、カバー部材２０の上側面４４とベース部材３０の上側面５４と並列に密着して、制御基板ケース１０の上側面６４を形成する（図４参照）。また、嵌挿凹部２３ａ（嵌挿凹部２３ｂ）の係合板２３２，２３３が、嵌挿凸部３３ａ（嵌挿凸部３３ｂ）の係止部３３３，３３４に各々嵌挿されて、嵌挿部１３ａ（嵌挿部１３ｂ）が形成される。 Then, as shown in FIGS. 10 and 11, in the control board case 10, when the insertion recess 23 a (insertion recess 23 b) and the insertion protrusion 33 a (insertion protrusion 33 b) are engaged, the cover The upper side surface 44 of the control board case 10 is formed in close contact with the upper side surface 44 of the member 20 and the upper side surface 54 of the base member 30 (see FIG. 4). Further, the engagement plates 232 and 233 of the insertion recess 23a (insertion recess 23b) are respectively inserted into the locking portions 333 and 334 of the insertion protrusion 33a (insertion protrusion 33b), and the insertion portion 13a. (Insertion portion 13b) is formed.

なお、上記の構成による嵌挿部１３ａ，１３ｂでは、係合板２３２，２３３の端部が制御基板ケース１０の背面方向（図１０の右方向）に突出することはない。また、封止板３３２の上端面は、カバー部材２０の上側面４４と同一平面上に位置するため、封止板３３２が制御基板ケース１０の上側面６４から上方向（図１１の上方向）に突出することもない。すなわち、制御基板ケース１０は、嵌挿部１３ａ，１３ｂによりカバー部材２０とベース部材３０とが密接に係合される結果、不必要な突出部位が生じず、かつその合わせ目の隙間が小さい構成となっている。 In the insertion portions 13a and 13b having the above-described configuration, the end portions of the engagement plates 232 and 233 do not protrude in the back direction of the control board case 10 (right direction in FIG. 10). Further, since the upper end surface of the sealing plate 332 is located on the same plane as the upper side surface 44 of the cover member 20, the sealing plate 332 is directed upward from the upper side surface 64 of the control board case 10 (upward direction in FIG. 11). It does not protrude. That is, the control board case 10 has a configuration in which an unnecessary protruding portion is not generated and a gap between the joints is small as a result of the cover member 20 and the base member 30 being closely engaged by the fitting insertion portions 13a and 13b.
