Description

本発明は、複数の電装基板に対して、ノイズを遮蔽するためのシールド部材を設けた遊技機に関する発明である。 The present invention relates to a gaming machine in which a shielding member for shielding noise is provided for a plurality of electrical boards.

一般に、パチンコ機等の遊技機内において使用されるパチンコ球は、球通路を流下する過程で摩擦により静電気が帯電されやすい。このパチンコ球の静電気等によって発生するノイズの影響でメイン制御基板、払出制御基板、電源基板等の電装基板が誤動作することを防止するために、各電装基板と遊技機の本体枠側（例えば、遊技盤の裏面側や機構板の裏面側等）との間に、それぞれノイズを遮蔽するためのシールド部材（例えば金属板等）を介在させるようにしたものがある。 In general, a pachinko ball used in a gaming machine such as a pachinko machine is easily charged with static electricity by friction in a process of flowing down the ball passage. In order to prevent malfunction of the electrical control boards such as the main control board, the payout control board, and the power supply board due to the noise generated by the static electricity of the pachinko balls, the main body frame side of each electrical board and the gaming machine (for example, In some cases, a shield member (for example, a metal plate or the like) for shielding noise is interposed between the back side of the game board or the back side of the mechanism board.

このような各電装基板のシールド部材は、帯電防止のためにアース接続する必要があり、そのために、各電装基板のシールド部材に、それぞれアース線を接続して遊技機の適宜箇所にアース接続したり、或は、各電装基板のシールド部材を、それぞれビス等を介して電装基板のＧＮＤラインに電気的に接続してアース接続するようにしている。 Such a shield member of each electric circuit board must be grounded to prevent electrification, and for that purpose, a ground wire is connected to the shield member of each electric circuit board and connected to an appropriate place of the gaming machine. Alternatively, the shield member of each electric circuit board is electrically connected to the GND line of the electric circuit board via a screw or the like to be grounded.

しかし、これらの方法は、いずれも各電装基板のシールド部材毎に、それぞれアース接続する必要があるため、アース接続作業に手間が掛かり、その分、組立能率が低下するという欠点があった。 However, these methods all have a drawback in that it is necessary to perform ground connection for each shield member of each electric circuit board, so that the ground connection work is troublesome and the assembly efficiency is reduced accordingly.

そこで、特許文献１（特開平１１−３３３１１１号公報）に記載されているように、制御基板を収納した２つの制御ユニットに対して共通の１枚のシールド部材を設けることで、この共通の１枚のシールド部材をアース接続するだけでアース接続作業が済むようにしたものがある。 Therefore, as described in Patent Document 1 (Japanese Patent Laid-Open No. 11-333111), this common 1 is provided by providing a common shield member for the two control units containing the control board. There is one in which grounding work can be completed by simply grounding the shield members.

また、特許文献２（特開２００３−２１０８０１号公報）に記載されているように、制御基板を収納した２つの基板ボックスに、それぞれシールド部材を一体的に設け、各基板ボックスを本体枠側に組み付けたときに、各基板ボックスのシールド部材が互いに接触して電気的に接続されるようにすることで、いずれか１枚のシールド部材をアース接続するだけでアース接続作業が済むようにしたものがある。
特開平１１−３３３１１１号公報（第６頁、第２図等）特開２００３−２１０８０１号公報（第１２頁、第６図等） Further, as described in Patent Document 2 (Japanese Patent Application Laid-Open No. 2003-210801), shield members are integrally provided in two board boxes each containing a control board, and each board box is disposed on the main body frame side. When assembled, the shield members of each board box come into contact with each other and are electrically connected, so that only one of the shield members can be connected to the ground so that the ground connection work can be completed. There is.

しかし、上記特許文献１の技術では、複数の制御ユニットと本体枠側との間に共通の１枚のシールド部材を介在させることになるため、そのシールド部材の前面側（本体枠側）に配置された部品の検査、修理、交換等のメインテナンスを行う場合には、そのメインテナンス対象部品がいずれか一方の制御ユニットの前面側にしか存在していなくても、シールド部材と複数の制御ユニットを全て取り外す必要があり、その分、制御基板の信号線や電源線のコネクタの脱着作業等が多くなって、メインテナンス作業性があまり良くないという欠点がある。 However, in the technique of Patent Document 1, since a single shield member is interposed between the plurality of control units and the main body frame side, it is arranged on the front side (main body frame side) of the shield member. When performing maintenance such as inspection, repair, replacement, etc., even if the maintenance target part exists only on the front side of one of the control units, the shield member and the plurality of control units are all There is a disadvantage that the maintenance workability is not so good because it is necessary to remove it, and the work of attaching / detaching the signal line connector of the control board and the connector of the power supply line increases.

また、上記特許文献２の技術では、各基板ボックス毎にそれぞれシールド部材を一体的に設けるため、例えば、基板ボックスのメインテナンスを行うために、いずれかの基板ボックスを取り外す毎にシールド部材が取り外されることになる。このため、シールド部材が取り外される頻度が多く、その分、シールド部材同士の電気的接続不良が発生する可能性が高くなり、シールド部材の電気的接続の信頼性が低下するという欠点がある。 In the technique disclosed in Patent Document 2, a shield member is integrally provided for each substrate box. For example, in order to perform maintenance of a substrate box, the shield member is removed every time one of the substrate boxes is removed. It will be. For this reason, the shield member is frequently removed, and accordingly, there is a high possibility that the electrical connection failure between the shield members will occur, and the reliability of the electrical connection of the shield member is reduced.

本発明は、これらの事情を考慮してなされたものであり、従って本発明の目的は、複数の電装基板のシールド部材のアース接続作業を簡単化して組立性を向上させながら、遊技機のメインテナンス性及びシールド部材の電気的接続の信頼性を向上させることができる遊技機を提供することにある。 The present invention has been made in consideration of these circumstances. Therefore, the object of the present invention is to maintain a game machine while simplifying the ground connection work of the shield members of a plurality of electrical boards and improving the assemblability. It is an object of the present invention to provide a gaming machine capable of improving the reliability of the electrical connection and the electrical connection of the shield member.

上記目的を達成するために、本発明の請求項１に記載の遊技機は、遊技機側に設けられた取付部に配置された複数の電装基板に対して、それぞれノイズを遮蔽するためのシールド部材を設けたものにおいて、これらのシールド部材のうちの特定の電装基板用のシールド部材を該特定の電装基板と一体的又は別々に脱着可能に設けると共に、他の電装基板用のシールド部材を取付部に設置し、特定の電装基板を取付部に組み付けたときに、該特定の電装基板用のシールド部材の接触部が他の電装基板用のシールド部材の接触部に接触して電気的に接続されるように構成したものである。 In order to achieve the above object, a gaming machine according to claim 1 of the present invention is a shield for shielding noise from each of a plurality of electrical boards arranged in a mounting portion provided on the gaming machine side. Among these shield members, a shield member for a specific electrical board among these shield members is provided so as to be detachable integrally with or separately from the specific electrical board, and a shield member for another electrical board is attached. When a specific electrical board is assembled to the mounting part, the contact part of the shield member for the specific electrical board comes into contact with the contact part of the shield member for the other electrical board and is electrically connected It is configured as described above.

この構成では、いずれか１枚のシールド部材をアース接続するだけで複数の電装基板のシールド部材のアース接続作業が完了する。また、メインテナンス対象部品の裏面側に、特定の電装基板と一体的又は別々に脱着可能なシールド部材を配置すれば、そのシールド部材が取り外されることにより、そのシールド部材の前面側の部品のメインテナンスを行うことができるため、複数の電装基板を全て取り外す必要はなく、メインテナンス作業性が向上する。また、特定の電装基板を取り外すときにしかシールド部材が取り外されず、他の電装基板を取り外したときにはシールド部材が取付部側に設置されたまま残るため、シールド部材が取り外される頻度が少なくなり、その分、シールド部材同士の電気的接続不良が発生する可能性が少なくなって、シールド部材同士の電気的接続の信頼性が向上する。 In this configuration, the ground connection work of the shield members of the plurality of electrical boards is completed by simply grounding any one shield member. In addition, if a shield member that can be attached to or detached from a specific electrical board is arranged on the back side of the maintenance target component, the shield member is removed, so that the maintenance of the front side component of the shield member is reduced. Since it can be performed, it is not necessary to remove all the plurality of electrical boards, and maintenance workability is improved. In addition, the shield member is removed only when a specific electrical board is removed, and when the other electrical board is removed, the shield member remains installed on the mounting portion side, so the frequency of removing the shield member is reduced. Therefore, the possibility of poor electrical connection between shield members is reduced, and the reliability of electrical connection between shield members is improved.

この場合、請求項２のように、他の電装基板用のシールド部材を、遊技機側に設けられたグランド側導電部材に電気的に接続するようにすると良い。他の電装基板用のシールド部材は、他の電装基板を取り外してもシールド部材が取付部（遊技機側）に設置されたまま残るため、他の電装基板用のシールド部材を遊技機側に設けられたグランド側導電部材に電気的に接続しておけば、シールド部材とグランド側導電部材との電気的接続不良が発生する可能性が少なくなり、シールド部材のアース接続の信頼性が向上する。 In this case, as described in claim 2, it is preferable that the shield member for another electrical board is electrically connected to the ground side conductive member provided on the gaming machine side. Since the shield member for other electrical boards remains attached to the mounting part (the gaming machine side) even if the other electrical board is removed, the shield member for the other electrical board is provided on the gaming machine side. If it is electrically connected to the ground-side conductive member, the possibility of an electrical connection failure between the shield member and the ground-side conductive member is reduced, and the reliability of the ground connection of the shield member is improved.

また、請求項３のように、特定の電装基板用のシールド部材と他の電装基板用のシールド部材のうちの少なくとも一方に、接触部を弾性変形可能に形成するようにすると良い。このようにすれば、シールド部材の接触部を弾性変形させて相手側のシールド部材の接触部に適度な弾性力で圧接させることができ、シールド部材同士の電気的接続の信頼性を更に向上させることができる。 According to a third aspect of the present invention, the contact portion may be formed to be elastically deformable on at least one of the shield member for a specific electrical board and the shield member for another electrical board. If it does in this way, the contact part of a shield member can be elastically deformed, and it can press-contact with the contact part of the other party shield member with moderate elastic force, and further improves the reliability of the electrical connection of shield members. be able to.

一般に、制御基板等の電装基板は、不正防止のために基板ボックス内に収容されているため、請求項４のように、接触部を電装基板を収容する基板ボックスの側方に突出させて、接触部と基板ボックスとの間に該接触部が弾性変形するための隙間を設けるようにすると良い。このようにすれば、基板ボックスの側方に突出させたシールド部材の接触部を確実に弾性変形させることができる。 Generally, an electrical board such as a control board is housed in a board box for preventing fraud, so that, as in claim 4, the contact portion protrudes to the side of the board box that houses the electrical board, A gap for elastically deforming the contact portion may be provided between the contact portion and the substrate box. If it does in this way, the contact part of the shield member protruded to the side of the substrate box can be elastically deformed reliably.

また、シールド部材には、バネ性のある銅板等で形成した弾性変形可能な接触部を別部品で取り付けるようにしても良いが、請求項５のように、シールド部材を、導電性の金属板で形成し、その一部に接触部を一体的に形成するようにしても良い。このようにすれば、シールド部材の接触部を別部品で設ける必要がなく、部品点数を削減して低コスト化することができる。 In addition, the shield member may be provided with an elastically deformable contact portion formed of a springy copper plate or the like as a separate part. However, as in claim 5, the shield member may be a conductive metal plate. The contact portion may be formed integrally with a part thereof. In this way, it is not necessary to provide the contact portion of the shield member as a separate part, and the number of parts can be reduced and the cost can be reduced.

また、請求項６のように、特定の電装基板と他の電装基板とが遊技機に対して前後方向に段差をつけて配置されている場合には、特定の電装基板用のシールド部材と他の電装基板用のシールド部材のうちの少なくとも一方は、接触部を前後方向に延びるように設けるようにすると良い。このようにすれば、特定の電装基板と他の電装基板とが前後方向に段差をつけて配置されている場合でも、リード線や他の接続部材等を用いずに、特定の電装基板用のシールド部材の接触部と他の電装基板用のシールド部材の接触部とを直接、接触させて電気的に接続することができる。 Further, when the specific electrical board and the other electrical board are arranged with a step in the front-rear direction with respect to the gaming machine as in claim 6, the shield member for the specific electrical board and the other At least one of the shield members for the electrical board may be provided with a contact portion extending in the front-rear direction. In this way, even when a specific electrical board and another electrical board are arranged with a step in the front-rear direction, the lead wire and other connection members are not used, and the specific electrical board can be used. The contact portion of the shield member and the contact portion of the shield member for another electrical board can be directly contacted to be electrically connected.

更に、請求項７のように、特定の電装基板を取付部に組み付ける際に、該特定の電装基板用のシールド部材の接触部を他の電装基板用のシールド部材の接触部に接触させる方向に該特定の電装基板を移動させるようにしても良い。このようにすれば、特定の電装基板用のシールド部材を他の電装基板用のシールド部材に確実に接触させることができ、シールド部材同士の電気的接続の信頼性を更に向上させることができる。 Further, as in claim 7, when assembling the specific electrical board to the mounting portion, the contact portion of the shield member for the specific electrical board is brought into contact with the contact portion of the shield member for the other electrical board. The specific electrical board may be moved. If it does in this way, the shield member for specific electrical equipment boards can be made to contact reliably the shield member for other electrical equipment boards, and the reliability of the electrical connection between shield members can further be improved.

また、請求項８のように、パチンコ球が流下する部材又は貯溜される部材（以下これらを「球流下部材」と総称する）を導電性材料で形成し、この球流下部材とシールド部材とを電気的に接続するようにしても良い。このようにすれば、静電気が帯電しやすい球流下部材を、シールド部材を介してアース接続することができ、球流下部材に帯電した静電気を除去することができる。 Further, as in claim 8, a member through which the pachinko ball flows down or a member to be stored (hereinafter collectively referred to as “ball flow-down member”) is formed of a conductive material, and the ball flow-down member and the shield member are formed. You may make it connect electrically. In this way, the ball flow-down member that is easily charged with static electricity can be grounded via the shield member, and the static electricity charged on the ball flow-down member can be removed.

A shield metal plate 26 (shield member) for shielding noise is interposed, and a shield metal plate 27 (shield member) is also interposed between the power supply substrate 25 and the back surface of the mechanism plate 12. These shield metal plates 26 and 27 are made of, for example, a metal plate such as a conductive iron plate or copper plate. A contact portion 28 is integrally formed by bending a part of the shield metal plate 26 for the payout control board 24, and a part of the shield metal plate 27 for the power supply board 25 is bent. Thus, the contact portion 29 that can be elastically deformed is integrally formed.

At the same time, the shield metal plate 27 for the power supply board 25 is fixed to the back surface of the mechanism plate 12 by elastically engaging the engagement claw 31 of the mechanism plate 12 with the engagement hole 33 of the shield metal plate 27.

更に、図３に示すように、電源基板ボックス２３の上端部と下端部には、それぞれねじ孔３４と係合部３５が設けられ、電源基板ボックス２３の係合部３５を機構板１２の被係合部３６に差し込んで係合させた状態で、電源基板ボックス２３のねじ孔３４に挿通したねじ（図示せず）を機構板１２のボス部３７に締め付けることで、電源基板基板ボックス２３が機構板１２の裏面に脱着可能に取り付けられている。これにより、電源基板ボックス２３（電源基板２５）と機構板１２の裏面との間に、電源基板２５用のシールド板金２７が介在されている。 Further, as shown in FIG. 3, screw holes 34 and engaging portions 35 are respectively provided at the upper end portion and the lower end portion of the power supply board box 23, and the engagement portions 35 of the power supply board box 23 are connected to the mechanism plate 12. In a state where the power supply board substrate box 23 is inserted into the engagement portion 36 and is engaged, a screw (not shown) inserted through the screw hole 34 of the power supply board box 23 is fastened to the boss portion 37 of the mechanism plate 12. The mechanism plate 12 is detachably attached to the back surface of the mechanism plate 12. Thereby, the shield metal plate 27 for the power supply board 25 is interposed between the power supply board box 23 (power supply board 25) and the back surface of the mechanism plate 12.

図２に示すように、電源基板２５用のシールド板金２７の接触部２９は、電源基板ボックス２３の側方に突出するように形成され、接触部２９と電源基板ボックス２３の側面との間には接触部２９が弾性変形するための隙間が設けられている。 As shown in FIG. 2, the contact portion 29 of the shield metal plate 27 for the power supply board 25 is formed so as to protrude to the side of the power supply board box 23, and between the contact portion 29 and the side surface of the power supply board box 23.
