Description

本発明は、パチンコ機、スロットマシーン等の遊技機用制御装置に関するものである。   The present invention relates to a control device for a game machine such as a pachinko machine and a slot machine.

遊技機の一種であるパチンコ機には、制御装置が設けられており、内部の基板上にROMやCPU等の制御素子が設置されている。かかる制御素子は、パチンコ機の作動内容を制御するものであるため、パチンコ機が遊技者にとって都合良く作動するように、不正に取り替えられたり不正に改造されたりすることがある。このため、かかる不正を防止するために、図12の如く、制御装置51の左右両側にカバー52とシャーシ53とに跨るように封印シート57,57を貼着する不正防止手段が講じられる。この不正防止手段によれば、制御装置51のカバー52が取り外されると、封印シート57,57が直ちに破れるため、制御素子が不正に取り替えられたり、改造されたりする事態を容易に発見することができる。したがって、パチンコ機が不正遊技者にとって都合良く作動する事態を防止することができる。
一方、従来の制御装置51は、基板56の裏面と金属製のシャーシ53とが接触しないように、基板56の各コーナーが筒状体54,54・・を介してネジ55,55・・によってシャーシ53に螺着されており、基板56とシャーシ53との間に隙間が形成されている。なお、基板56の上端際には外部と接続する端子が設置されているため、基板56の左右上方の各コーナーのシャーシ53との螺着部分は、カバー52の外側に露出した状態になっている。
A pachinko machine, which is a kind of gaming machine, is provided with a control device, and a control element such as a ROM and a CPU is provided on an internal board. Since such a control element controls the operation of the pachinko machine, it may be improperly replaced or modified so that the pachinko machine operates conveniently for the player. Therefore, in order to prevent such fraud, as shown in FIG. 12, fraud prevention means for sticking sealing sheets 57, 57 to both sides of the control device 51 so as to straddle the cover 52 and the chassis 53 are taken. According to this fraud prevention means, when the cover 52 of the control device 51 is removed, the sealing sheets 57, 57 are immediately torn, so that it is easy to find a situation in which the control element is illegally replaced or modified. it can. Therefore, it is possible to prevent a situation in which the pachinko machine operates conveniently for the unauthorized player.
On the other hand, in the conventional control device 51, each corner of the substrate 56 is screwed with the screws 55, 55... Through the cylindrical bodies 54, 54, so that the back surface of the substrate 56 does not contact the metal chassis 53. It is screwed to the chassis 53, and a gap is formed between the board 56 and the chassis 53. Since terminals for connection to the outside are provided near the upper end of the board 56, screwing portions of the left and right upper corners of the board 56 with the chassis 53 are exposed outside the cover 52. I have.

しかしながら、上記の如く不正行為防止手段が講じられた制御装置51であっても、カバー52が取り外され、制御素子が不正に取り替えられ、あるいは不正に改造された後に、同一形状の偽造の封印シートが貼着された場合には、不正の事態を容易に発見することができず、パチンコ機が不正遊技者にとって都合良く作動する事態を防止することができない。また、パチンコホールを管轄している警察署がROM等の制御素子をチェックする場合等、正規の目的で制御装置51のカバー52を開放する場合には、再度、封印シート57,57を貼着し直さなければならないので、非常に煩わしい。さらに、従来の制御装置51は、基板56の左右上方の各コーナーとシャーシ53との螺着が不正に解除され、筒状体54,54が外されると、基板56の表面とカバー52との隙間を大きくすることができるため、かかる隙間が利用されて、制御素子が不正に取り替えられ、あるいは不正に改造されることもある。   However, even in the case of the control device 51 in which the improper action preventing means is provided as described above, the forged sealing sheet having the same shape after the cover 52 is removed and the control element is improperly replaced or improperly modified. Is attached, it is not possible to easily detect a fraudulent situation, and it is not possible to prevent a situation in which a pachinko machine operates conveniently for a fraudulent player. When the cover 52 of the control device 51 is opened for a legitimate purpose, such as when a police station in charge of the pachinko hall checks a control element such as a ROM, the sealing sheets 57, 57 are attached again. It is very annoying because I have to do it again. Further, when the screwing between the left and right upper corners of the board 56 and the chassis 53 is illegally released and the tubular bodies 54 are removed, the conventional control device 51 Since the gap can be increased, the gap may be used, and the control element may be improperly replaced or improperly modified.

そこで請求項1に記載の発明は、上記従来のパチンコ機の問題点を解消し、制御素子が不正取り替え、不正改造される事態を防止することができるとともに、万が一、不正取り替え、不正改造された場合には、直ちにその事態を発見することができ、その上、制御素子を容易にチェックすることができる遊技機用制御装置を提供することを目的としたものである。   Therefore, the invention according to claim 1 solves the problems of the conventional pachinko machine, can prevent a situation in which the control element is improperly replaced or tampered with, and in the unlikely event that the pachinko machine has been tampered with or replaced illegally. In this case, it is an object of the present invention to provide a gaming machine control device that can immediately detect the situation, and can easily check a control element.

制御装置3は、下カバー10の表側にシャーシ4が配置され、シャーシ4の表側に基板8が配置された状態で、基板8の各コーナー際のネジ孔30,30・・とシャーシ4の各基板取付部22,22・・と下カバー10の各ネジ止めタブ28,28・・とが螺着されることによって、シャーシ4と下カバー10と基板8とが一体的に組み立てられている。さらに、その下カバー10に、上カバー9が、各上固着翼13,13を各下固着翼26,26に重ね合わせ、各係合片21,21を各係合凹部31,31に係合させた状態で、左側の最上方のネジ保持部14を左側の最上方の取付タブ27に、右側の最下方のネジ保持部14を右側の最下方の取付タブに、それぞれ、各ネジ保持部14内の木ネジ19によって螺着することによって、合着されている。そして、基板8が、上カバー9によって、基板8表面との間に隙間が形成されることなく覆われた状態になっている。   The control device 3 is configured such that the chassis 4 is arranged on the front side of the lower cover 10, and the board 8 is arranged on the front side of the chassis 4, and the screw holes 30, 30. The chassis 4, the lower cover 10, and the board 8 are integrally assembled by screwing the board mounting portions 22, 22... And the screw fixing tabs 28, 28. Further, on the lower cover 10, the upper cover 9 overlaps the upper fixed wings 13, 13 with the lower fixed wings 26, 26, and engages the engagement pieces 21, 21 with the engagement recesses 31, 31. In this state, the uppermost screw holding section 14 on the left is attached to the uppermost mounting tab 27 on the left side, and the lowermost screw holding section 14 on the right is attached to the lowermost mounting tab on the right. It is joined by screwing with a wood screw 19 in 14. Then, the substrate 8 is covered by the upper cover 9 without forming a gap between the substrate 8 and the surface of the substrate 8.

かかる制御装置3においては、上カバー9のネジ保持部14と下カバー10の取付タブ27とが、ワンウェイタイプの木ネジ19によって螺着されているため、木ネジ19を螺着時と反対方向(左回り)に回転させても、螺着状態が解除されない(すなわち、ネジ保持部14と取付タブ27との螺着状態は解除されない)。それゆえ、基板8上に設置されたROM11等の制御素子の内容をチェックする等のために上カバー9を取り外す場合には、取付タブ27と螺着したネジ保持部14(すなわち、左側の最上方のネジ保持部14と右側の最下方のネジ保持部14)の前方に設けられた3つの取付片15,15・・を、ニッパ等の工具で切断し、かかるネジ保持部14を上カバー9から切り離すことによって、上カバー9と下カバー10とを分離しなければならない。また、再度上カバー9を下カバー10に合着させる場合には、左側の最上方のネジ保持部14および右側の最下方のネジ保持部14以外のネジ保持部14(すなわち、未だ取付タブ27と螺着していないネジ保持部14)を、同位置の取付タブ27と螺着すれば良い。それゆえ、制御装置においては、ROM11等の制御素子の内容をチェックしても、再度、上カバー9を下カバー10に合着させることができ、かかる上下カバー9,10の分離、合着を3回繰り返すことができる。   In the control device 3, since the screw holding portion 14 of the upper cover 9 and the mounting tab 27 of the lower cover 10 are screwed by the one-way type wood screw 19, the wood screw 19 is turned in the opposite direction to the screwing direction. Even when rotated counterclockwise, the screwed state is not released (that is, the screwed state between the screw holding portion 14 and the mounting tab 27 is not released). Therefore, when removing the upper cover 9 to check the contents of the control element such as the ROM 11 installed on the board 8, the screw holding portion 14 screwed to the mounting tab 27 (that is, the leftmost The three mounting pieces 15, 15,... Provided in front of the upper screw holding portion 14 and the right lowermost screw holding portion 14) are cut with a tool such as a nipper, and the screw holding portion 14 is covered with an upper cover. 9, the upper cover 9 and the lower cover 10 must be separated. Further, when the upper cover 9 is attached to the lower cover 10 again, the screw holding portions 14 other than the uppermost screw holding portion 14 on the left side and the lowermost screw holding portion 14 on the right side (that is, the mounting tabs 27 still remain). The screw holding portion 14) which is not screwed with the mounting tab 27 may be screwed with the mounting tab 27 at the same position. Therefore, in the control device, even if the contents of the control elements such as the ROM 11 are checked, the upper cover 9 can be attached to the lower cover 10 again, and the separation and attachment of the upper and lower covers 9 and 10 can be performed. Can be repeated three times.

制御装置3は、上記の如く、上カバー9を下カバー10と分離するためには、3つの取付片15,15・・を切断することにより下カバー10の取付タブ27と螺着されたネジ保持部14を上カバー9から切り離さなければならない構造であるため、不正に上カバー9が取り外された場合には、必ずその痕跡が残る。それゆえ、容易に不正の事態を発見することができ、不正遊技者にとって都合良く作動する事態を未然に防止することができる。
又ここでは、各ネジ保持部14は保護カバーとなる上固着翼13に周囲を囲まれる格好となっているから、各ネジ保持部14に外力が加わって取付片15,15・・が破断し、ネジ保持部14が偶発的に切断してしまうような虞れはなくなる。
In order to separate the upper cover 9 from the lower cover 10 as described above, the control device 3 cuts the three mounting pieces 15, 15,. Since the holding portion 14 has to be separated from the upper cover 9, if the upper cover 9 is removed improperly, a trace is always left. Therefore, it is possible to easily detect a fraudulent situation, and prevent a situation in which the fraudulent player operates conveniently.
Also, in this case, since each screw holding portion 14 is surrounded by the upper fixed wing 13 serving as a protective cover, an external force is applied to each screw holding portion 14, and the mounting pieces 15, 15,. Therefore, there is no possibility that the screw holding portion 14 is accidentally cut.

上記の如き効果を有しているにも拘わらず、制御装置3は、各ネジ保持部14,14・・の前面に設けられた取付片15,15・・が容易に切断可能な構造を有しているため、それらの取付片15,15・・をニッパ等の工具で切断することによって、上カバー9を容易に取り外すことができ、基板8上に設置された制御素子の内容を簡単にチェックすることができる。   Despite having the above-described effects, the control device 3 has a structure in which the mounting pieces 15, 15,... Provided on the front surfaces of the screw holding sections 14, 14,. , The upper cover 9 can be easily removed by cutting the mounting pieces 15, 15,... With a tool such as a nipper, and the contents of the control elements installed on the substrate 8 can be easily reduced. You can check.

また、制御装置3は、シャーシ4の各コーナー際に、基板取付部22,22・・が、高い強度を発現できるように一体的に突設されており、それらの基板取付部22,22・・に、基板8の各コーナーが螺着されているとともに、基板8が、上カバー9によって、基板8表面との間に大きな隙間が形成されることなく覆われているため、基板8とシャーシ4と下カバーとの螺着部分の内の上カバー9の外側に露出している部分の螺着が不正に解除された場合でも、上カバー9と基板8表面との間に隙間が形成されない。それゆえ、上カバー9と基板8表面との隙間から制御素子が不正に取り替えられたり、改造されたりする事態を未然に防止することができる。さらに、かかる不正防止効果は、上カバー9と基板8表面との間の隙間が小さくなるほど、より確実なものとなる。   Further, in the control device 3, at each corner of the chassis 4, the board mounting portions 22, 22... Are integrally protruded so as to exhibit high strength, and the board mounting portions 22, 22. Since each corner of the substrate 8 is screwed and the substrate 8 is covered by the upper cover 9 without forming a large gap between the substrate 8 and the surface of the substrate 8, the substrate 8 and the chassis No gap is formed between the upper cover 9 and the surface of the substrate 8 even if the screwing of the portion of the screwing portion between the upper cover 9 and the lower cover exposed outside the upper cover 9 is illegally released. . Therefore, it is possible to prevent a situation in which the control element is illegally replaced or remodeled from the gap between the upper cover 9 and the surface of the substrate 8. Further, such a fraud prevention effect becomes more reliable as the gap between the upper cover 9 and the surface of the substrate 8 becomes smaller.

次にネジ保持部14の変更例を説明する。まずここでは、上カバー9の開放作業が、ニッパー等の工具を使用せずに簡単に行える形態を説明する。即ち、図9〜11に示すように、ネジ保持部14と上固着翼13との間を連結する一対の取付片33,33を、夫々細板状に形成すると共に、各取付片33,33には、上固着翼13の上面と平行な切込み34,34を形成して、当該部分を薄肉部33a,33aとしたものである。これによれば、一旦封止した上カバー9を開放する際には、ネジ締めされているネジ保持部14の取付片33を、図11(B)で示すように、指で切込み34と反対側に押し倒せば、取付片33は薄肉部33a部分で簡単に破断し、ネジ保持部14と上固着翼13との連結を容易に解除することができる。よって工具が不要となって封止解除の作業が向上する。   Next, a modified example of the screw holding unit 14 will be described. First, a mode in which the opening operation of the upper cover 9 can be easily performed without using a tool such as a nipper will be described. That is, as shown in FIGS. 9 to 11, a pair of attachment pieces 33, 33 for connecting between the screw holding portion 14 and the upper fixed wing 13 are formed in a thin plate shape, respectively, and the respective attachment pieces 33, 33 are provided. Are formed with cuts 34, 34 parallel to the upper surface of the upper fixed blade 13, and the corresponding portions are made into thin portions 33a, 33a. According to this, when the upper cover 9 once sealed is opened, the mounting piece 33 of the screw holding portion 14 which has been screwed is opposite to the cut 34 with a finger as shown in FIG. 11B. If pushed down to the side, the attachment piece 33 is easily broken at the thin portion 33a, and the connection between the screw holding portion 14 and the upper fixed wing 13 can be easily released. Therefore, a tool is not required, and the operation of releasing the seal is improved.

一方、先の形態においては、木ネジ19のネジ保持部14への締付時に、ネジ保持部14にネジ締め方向への回転力が作用し、そのため取付片15,15・・が破断してネジ保持部14が上固着翼13から分離してしまう虞れもある。よってこのような不具合の発生を効果的に防止するために、ここでは図10に示すように、筒状のネジ保持部14の下端を上記形態より若干下カバー10側へ長くし、その下端に、下カバー10の取付タブ27,27・・に放射状に形成されたリブ27a,27a・・が嵌合する溝32,32・・を形成すれば良い。これによれば、上下カバー9,10を組付けると、図11(B)の如く各取付タブ27,27・・におけるリブ27a,27a・・が、各ネジ保持部14,14・・における溝32,32・・に係合し、各ネジ保持部14,14・・の回転が規制されるため、木ネジ19のネジ締めによっても各ネジ保持部14は回転せず、上カバー9から切断することもない。   On the other hand, in the above embodiment, when the wood screw 19 is fastened to the screw holding portion 14, a rotational force in the screw tightening direction acts on the screw holding portion 14, so that the mounting pieces 15, 15,. There is a possibility that the screw holding portion 14 may be separated from the upper fixed blade 13. Therefore, in order to effectively prevent the occurrence of such a problem, as shown in FIG. 10, the lower end of the cylindrical screw holding portion 14 is slightly longer than the above-described embodiment toward the lower cover 10. The grooves 32, 32, into which the radially formed ribs 27a, 27a,... Fit in the mounting tabs 27, 27,. According to this, when the upper and lower covers 9, 10 are assembled, the ribs 27a, 27a,... In the mounting tabs 27, 27,. , 32, 32,..., And the rotation of the screw holding portions 14, 14,... Is restricted. Therefore, even when the wood screw 19 is tightened, the screw holding portions 14 do not rotate, and are cut from the upper cover 9. Nothing to do.

なお、ネジ保持部14の移動を規制する係合部となるリブ27aと溝32とは、少なくとも対応する1箇所ずつあれば良く、これらの具体的形状も適宜変更可能である。また、変更例の取付片33,33は細板状としているが、指で押し倒して切断できる形状であれば、棒状や円盤状等他の形状でも差し支えない。さらに上カバー9も、上固着翼13が形成されない場合、単純に上カバー9の側方に薄肉部で連結されるネジ保持部14を突設し、それらの周囲を壁状の保護カバーで囲むようにすることもできる。   The ribs 27a and the grooves 32 serving as the engagement portions for restricting the movement of the screw holding portion 14 may be at least one corresponding position, and their specific shapes can be appropriately changed. Further, the attachment pieces 33, 33 in the modified example are formed in a thin plate shape, but may be in other shapes such as a rod shape or a disk shape as long as they can be pushed down with a finger and cut. Further, when the upper fixed wings 13 are not formed, the upper cover 9 is also provided with a screw holding portion 14 simply connected to the side of the upper cover 9 with a thin portion, and the periphery thereof is surrounded by a wall-shaped protective cover. You can also do so.
