Description

本発明は、遊技者に押圧操作される遊技機用の押しボタン部材を備え、押しボタン部材の内部に配置された基板が静電気により破壊されてしまうことを防止できる押しボタンユニット体に関する。   The present invention relates to a push button unit body that includes a push button member for a gaming machine that is pressed by a player and that can prevent a substrate disposed inside the push button member from being destroyed by static electricity.

電子機器に備えられた操作ボタン等にあっては、例えば特許文献１に開示されているように、操作スイッチのキートップと、キートップを押し下げると電気的に接続される接点部とを有する構成は既に知られている。さらに、かかる構成にあっては、キートップ等に発生した静電気を外装ケースに良好に逃がすべく、キートップの近傍に導通面が設けられている。   In an operation button or the like provided in an electronic device, for example, as disclosed in Patent Document 1, a configuration having a key top of an operation switch and a contact portion that is electrically connected when the key top is depressed. Is already known. Furthermore, in such a configuration, a conduction surface is provided in the vicinity of the key top so that static electricity generated in the key top or the like can be released to the exterior case satisfactorily.

また、スロットマシン等の遊技機にあっては、例えば特許文献２に開示されているように、ユニット化されている操作ボタン装置が既に知られている。かかる構成にあっては、電子銃等を用いた不正操作等を防止すべく、操作ボタンユニットとカバー部材との間に、導電材料からなるシールド板が挟持されており、シールド板がアース接続されている。   As for gaming machines such as slot machines, for example, as disclosed in Patent Document 2, a unitized operation button device is already known. In such a configuration, a shield plate made of a conductive material is sandwiched between the operation button unit and the cover member to prevent unauthorized operation using an electron gun or the like, and the shield plate is grounded. ing.

さらに、例えば特許文献３には、遊技者が操作する始動レバーのツマミ部を有し、ツマミ部の静電気を除電するアルミテープが貼り付けられた遊技機が開示されている。   Further, for example, Patent Document 3 discloses a gaming machine having a knob portion of a start lever operated by a player and having an aluminum tape attached to remove static electricity from the knob portion.

特開２０００−３２３２９５号公報JP 2000-323295 A 特開２００９−１７２２１６号公報JP 2009-172216 A 特開２００８−１８８２８１号公報JP 2008-188281 A

しかしながら、特許文献１に開示されている構成は、操作スイッチ構造全体がユニット化されていないため、操作スイッチを本体に取り付ける作業工程と、静電気対策のための構造を施す作業工程とが個別に必要となる。例えば、静電気対策の作業工程の一例として、キートップ周囲の金属ケースの一部を削り取って導通面を露出させるという非常に煩雑な構成が開示されている。   However, since the entire configuration of the operation switch structure is not unitized in the configuration disclosed in Patent Document 1, a work process for attaching the operation switch to the main body and a work process for applying a structure for preventing static electricity are separately required. It becomes. For example, as an example of a work process for countermeasures against static electricity, a very complicated configuration is disclosed in which a part of a metal case around a key top is scraped to expose a conductive surface.

また、特許文献２に開示されている操作ボタン装置は、アース接続されたシールド板自体が操作ボタン装置の内部に組み込まれており、全体として操作ボタン装置が大型化してしまうという問題がある。   Further, the operation button device disclosed in Patent Document 2 has a problem that the shield plate itself connected to the ground is incorporated in the operation button device, and the operation button device is enlarged as a whole.

さらに、特許文献３に開示されている構成は、アルミテープが筐体側に配置されており、レバー構造がユニット化されていないため、ツマミ部等を本体に取り付ける作業工程と、アルミテープを筐体側に貼り付ける作業工程とが個別に必要となり、構造も複雑化してしまう。   Further, the configuration disclosed in Patent Document 3 is such that the aluminum tape is arranged on the housing side and the lever structure is not unitized. Therefore, the work process for attaching the knob portion etc. to the main body, and the aluminum tape on the housing side The work process to be attached to the sheet is required separately, and the structure becomes complicated.

そこで、本発明は、電気的な不正操作や静電気による誤動作等に対する静電気対策が既になされ、またコンパクト化され、また遊技機本体への取付け作業が簡便となる押しボタンユニット体を提供することを目的とする。   Accordingly, an object of the present invention is to provide a push button unit body that has already been subjected to static electricity countermeasures against electrical unauthorized operation or malfunction due to static electricity, is compact, and can be easily attached to a gaming machine body. And

本発明は、遊技機本体に装着され、遊技者に押圧操作される押しボタン部材を備える押しボタンユニット体であって、前記遊技機本体に固定され、遊技者側に開放された押しボタン収容空間を有するベース体と、前記ベース体の押しボタン収容空間内に配置された押しボタン部材と、前記ベース体に固定され、電子部品が実装された基板と、を備え、前記押しボタン部材は、該押しボタン部材の押圧方向に沿って前記ベース体に対して進退し、かつ遊技者側に開放された基板収容空間を有するプランジャー体と、前記基板収容空間を遮蔽するように前記プランジャー体に装着されるカバー体と、を具備し、前記基板は、前記ベース体に固定された状態で前記基板収容空間内に配置され、かつ、前記押しボタン部材の側方を囲繞する前記ベース体の側壁部のうち、前記プランジャー体と前記カバー体との境界部の少なくとも一部に対向する位置に、導電性を有する基板保護用導電部が配置されており、前記基板保護用導電部に対向する前記境界部は、前記押しボタン部材の側面に配置されていることを特徴とする押しボタンユニット体である。 The present invention is a push button unit body that is mounted on a gaming machine body and includes a push button member that is pressed by a player, and is a push button housing space that is fixed to the gaming machine body and opened to the player side. A base body, a push button member disposed in the push button accommodating space of the base body, and a substrate mounted on the base body and mounted with electronic components, the push button member comprising A plunger body having a substrate housing space that advances and retreats with respect to the base body along the pressing direction of the push button member and is open to the player side, and the plunger body so as to shield the substrate housing space comprising a cover member to be mounted, the said base said substrate is disposed on the substrate housing space in a state of being fixed to the base body, and surrounding the side of the push button member Of the side wall portion, at a position facing at least a part of a boundary portion between the cover member and the plunger member, a substrate protective conductive part having conductivity is arranged, on the substrate protective conductive portion The opposing boundary portion is a push button unit body arranged on a side surface of the push button member.

かかる構成は、基板をプランジャー体内に配置しているため、押しボタンユニット体全体の厚みを薄くすることが可能となり、結果としてコンパクト化された構造となっている。加えて、ユニット化された構造であるため、遊技機本体への取付け作業が簡便となっている。   In such a configuration, since the substrate is disposed in the plunger body, the thickness of the entire push button unit body can be reduced, and as a result, the structure is made compact. In addition, since it is a unitized structure, the attachment work to the gaming machine body is simple.

また、上記した構成では、基板をプランジャー体内に配置したことにより、遊技者が触れる押しボタン部材の表面と基板との距離が近くなる。このため、例えば静電気が溜まった遊技者が押しボタン部材の表面に触れることで押しボタン部材の表面等を静電気が流れると、静電気は境界部を介してプランジャー体内の基板に向かいやすくなる。しかし、本発明は、境界部に対向する位置に基板保護用導電部を配置したため、かかる静電気を、プランジャー体内に侵入する前に基板保護用導電部に誘引することが可能となる。
以上のように、本発明に係る押しボタンユニット体は、静電気対策が既になされたユニット構造となり、遊技機本体への取付け作業と静電気対策のための作業が共に簡便となる。 In the above-described configuration, since the board is arranged in the plunger body, the distance between the surface of the push button member touched by the player and the board is reduced. For this reason, for example, when a player who has accumulated static electricity touches the surface of the push button member and the static electricity flows through the surface of the push button member, the static electricity is likely to face the substrate in the plunger body through the boundary portion. However, according to the present invention, since the substrate protection conductive portion is disposed at a position facing the boundary portion, it is possible to attract the static electricity to the substrate protection conductive portion before entering the plunger body.
As described above, the push button unit body according to the present invention has a unit structure in which countermeasures against static electricity have already been taken, and both the work for mounting on the gaming machine body and the work for countermeasures against static electricity are simplified.

ところで、押しボタン部材の静電気対策として、押しボタン部材自体に直接アース接続を行う等の対策が通常考えられる。しかし、押しボタン部材は、押圧されることでベース体に対して進退する可動部材であり、このような可動部材を常時アース接続させておく構成は、可動部材が進退してもアース接続をするための配線が他の部材と干渉しないように考慮する必要や、可動部材が進退しても配線に負荷がかからないように配線を配置する必要などがあり、設計が煩雑で面倒となり、結果的に構造が複雑化してしまう。また、場合によっては、押しボタン部材が繰り返し進退することでアース接続に繋がる部分が疲労し、クラック等が発生する等して静電気対策が長期にわたって維持できないおそれもある。
しかし、本発明にあっては、基板保護用導電部がベース体の側壁部に配置されており、基板保護用導電部と押しボタン部材とが連動しないため、構造が複雑化せず設計を簡単にすることができ、上述したようなクラック等の問題も生じない。 By the way, as a countermeasure against static electricity of the push button member, a measure such as a direct ground connection to the push button member itself is usually considered. However, the push button member is a movable member that moves forward and backward with respect to the base body when pressed, and the configuration in which such a movable member is always connected to the ground makes the ground connection even if the movable member moves forward and backward. For example, it is necessary to consider the wiring so that it does not interfere with other members, and it is necessary to arrange the wiring so that no load is applied to the wiring even if the movable member moves back and forth. The structure becomes complicated. In some cases, the push button member repeatedly advances and retreats, so that the portion connected to the ground connection is fatigued, cracks and the like are generated, and there is a possibility that the countermeasure against static electricity cannot be maintained for a long time.
However, in the present invention, the conductive portion for protecting the substrate is disposed on the side wall portion of the base body, and the conductive portion for protecting the substrate and the push button member are not interlocked, so the structure is not complicated and the design is simple. The above-described problems such as cracks do not occur.

また、基板保護用導電部は、遊技者側から隠れて見えないため、美観に優れている。
なお、基板保護用導電部は、押しボタン部材が押圧されたときにのみ境界部と対向してもよいし、押しボタン部材が押圧されていないときにのみ境界部と対向してもよいし、勿論、押圧されているか否かに関わらず、押しボタン部材のいずれの位置においても境界部と対向していてもよい。 Moreover, since the conductive part for protecting the substrate is hidden from the player side and cannot be seen, it is excellent in aesthetics.
The conductive portion for protecting the substrate may be opposed to the boundary portion only when the push button member is pressed, or may be opposed to the boundary portion only when the push button member is not pressed, Of course, it may be opposed to the boundary portion at any position of the push button member regardless of whether or not it is pressed.

また、本発明に係る押しボタンユニット体の具体的な構成として、前記基板と前記カバー体との間に、遊技者側から視認可能な装飾部材が配置され、前記装飾部材の表面は導電性を有し、前記基板保護用導電部と対向する前記境界部のうち少なくとも一部と該装飾部材の一部とが対向し、かつ、前記基板保護用導電部と対向しない前記境界部の一部と前記装飾部材の他の一部とが対向している構成が提案される。   Further, as a specific configuration of the push button unit body according to the present invention, a decorative member visible from the player side is disposed between the substrate and the cover body, and the surface of the decorative member is made conductive. And at least a part of the boundary part facing the conductive part for substrate protection and a part of the decorative member are opposed to each other, and a part of the boundary part not opposed to the conductive part for substrate protection A configuration in which the other part of the decorative member is opposed is proposed.

かかる構成にあっては、押しボタン部材内に、遊技者の関心を惹く装飾部材をコンパクトに配置することができるため、遊技機の意匠性を向上させることができる。
加えて、仮に、基板保護用導電部と対向しない境界部の部分の周辺に静電気が帯電した場合にも、装飾部材を介して基板保護用導電部に静電気を適切に誘引することが可能となる。 In such a configuration, the decorative member that attracts the player's interest can be compactly arranged in the push button member, so that the design of the gaming machine can be improved.
In addition, even if static electricity is charged around the boundary portion that does not face the conductive portion for protecting the substrate, it is possible to appropriately attract the static electricity to the conductive portion for protecting the substrate through the decorative member. .

本発明を遊技機としてのスロットマシンに適用した実施形態を、以下の実施例に従って説明する。   An embodiment in which the present invention is applied to a slot machine as a gaming machine will be described according to the following examples.

〔実施例１〕
実施例１の押しボタンユニット体１０Ａを図１〜図５に従って説明する。
押しボタンユニット体１０Ａは、図１に示すように、スロットマシンの遊技機本体１に装着される。 [Example 1]
A push button unit body 10A according to the first embodiment will be described with reference to FIGS.
As shown in FIG. 1, the push button unit body 10A is attached to the gaming machine main body 1 of the slot machine.

押しボタンユニット体１０Ａは、図１，図３に示すように、遊技者側に開放された押しボタン収容空間Ｘを有する箱形形状をなしたベース体２０を備えている。そして、ベース体２０の押しボタン収容空間Ｘ内に、遊技者に押圧操作される演出ボタンである押しボタン部材３０が配置されている。   As shown in FIGS. 1 and 3, the push button unit body 10 </ b> A includes a base body 20 having a box shape having a push button accommodation space X opened to the player side. A push button member 30, which is an effect button that is pressed by the player, is disposed in the push button accommodating space X of the base body 20.

ベース体２０は、押しボタン収容空間Ｘを囲繞する側壁部２１を具備しており、その外側面には、固定用孔２２が設けられた一対の固定用突片２３が設けられている。なお、固定用孔２２には、固定手段としての金属製のボルト（図示省略）が挿通可能となっており、これによりベース体２０が遊技機本体１に固定される。   The base body 20 includes a side wall portion 21 that surrounds the push button accommodating space X, and a pair of fixing protrusions 23 provided with fixing holes 22 are provided on the outer surface thereof. Note that a metal bolt (not shown) as a fixing means can be inserted into the fixing hole 22, whereby the base body 20 is fixed to the gaming machine main body 1.

また、ベース体２０の底部には、ネジ台２４が押しボタン収容空間Ｘに向けて突出状に形成されている。そして、光透過型センサ４２やＬＥＤ素子４３等の電子部品が実装された基板４０が、ネジ４１（図１参照）を介してネジ台２４に取り付けられている。また、基板４０には、遊技機本体１に取り付けられた本体基板（図示省略）と電気的に接続される接続端子４４が備えられている。   A screw base 24 is formed on the bottom of the base body 20 so as to protrude toward the push button accommodating space X. And the board | substrate 40 with which electronic components, such as the light transmission type sensor 42 and the LED element 43, were mounted is attached to the screw stand 24 via the screw 41 (refer FIG. 1). The board 40 includes a connection terminal 44 that is electrically connected to a main board (not shown) attached to the gaming machine main body 1.

一方、押しボタン部材３０は、遊技者側に開放された基板収容空間Ｙを有するプランジャー体３１と、基板収容空間Ｙを遮蔽するようにプランジャー体３１に装着された透明性を有するカバー体３５と、を具備している。   On the other hand, the push button member 30 includes a plunger body 31 having a board housing space Y opened to the player side, and a transparent cover body attached to the plunger body 31 so as to shield the board housing space Y. 35.

プランジャー体３１は、押しボタン部材３０の押圧方向Ｍに沿ってベース体２０に対して進退可能な構造を有している。具体的には、図１に示すように、プランジャー体３１とベース体２０との間には、コイルバネ３８が配置されており、コイルバネ３８が、プランジャー体３１をベース体２０側から遊技者側に向けて付勢している。   The plunger body 31 has a structure capable of moving forward and backward with respect to the base body 20 along the pressing direction M of the push button member 30. Specifically, as shown in FIG. 1, a coil spring 38 is disposed between the plunger body 31 and the base body 20, and the coil spring 38 moves the plunger body 31 from the base body 20 side to the player. It is energizing towards the side.

また、図１，図３に示すように、プランジャー体３１の底部であって、コイルバネ３８の内空部に位置する箇所には、基板４０に実装された光透過型センサ４２の光路を遮光するための遮光板３２が遊技機本体１側に向かって突出状に形成されている。   As shown in FIGS. 1 and 3, the light path of the light transmission type sensor 42 mounted on the substrate 40 is shielded at a position located in the inner space of the coil spring 38 at the bottom of the plunger body 31. A light shielding plate 32 is formed so as to protrude toward the gaming machine main body 1 side.

さらに、プランジャー体３１の基板収容空間Ｙには、上述したベース体２０に固定された基板４０が配置されている。   Further, the substrate 40 fixed to the base body 20 is disposed in the substrate housing space Y of the plunger body 31.

そして、図１に示すように、プランジャー体３１の周縁部とカバー体３５の周縁部とが突き合わせされた部分によって、プランジャー体３１とカバー体３５との境界部３７が形成されている。   As shown in FIG. 1, a boundary portion 37 between the plunger body 31 and the cover body 35 is formed by a portion where the peripheral edge portion of the plunger body 31 and the peripheral edge portion of the cover body 35 abut each other.

さらに、図１〜図３に示すように、プランジャー体３１とカバー体３５との間には、遊技者側から視認可能で表面が導電性を有する板状の装飾部材５０が配置されている。装飾部材５０の外寸は、カバー体３５の内寸よりわずかに小さい寸法形状に設定されており、装飾部材５０の全周縁部が、境界部３７の全周と対向している。   Furthermore, as shown in FIGS. 1 to 3, a plate-shaped decorative member 50 that is visible from the player side and has a conductive surface is disposed between the plunger body 31 and the cover body 35. . The outer dimension of the decorative member 50 is set to a dimension slightly smaller than the inner dimension of the cover body 35, and the entire peripheral edge portion of the decorative member 50 faces the entire periphery of the boundary portion 37.

さらに、図１に示すように、ベース体２０の側壁部２１とプランジャー体３１との間、及び側壁部２１とカバー体３５との間にはそれぞれ隙間ｄが形成されており、押しボタン部材３０が進退する押圧操作された際にも、互いに干渉しない配置となっている。   Further, as shown in FIG. 1, gaps d are formed between the side wall portion 21 and the plunger body 31 of the base body 20 and between the side wall portion 21 and the cover body 35, respectively. Even when a pressing operation is performed to advance and retract 30, the arrangement does not interfere with each other.

なお、ベース体２０、プランジャー体３１、及びカバー体３５は、非導電性の樹脂材料によって形成されている。   Note that the base body 20, the plunger body 31, and the cover body 35 are formed of a non-conductive resin material.

上述した構成にあって、押しボタン部材３０が押圧されていない状態にあっては、カバー体３５の表面となる操作面３６が遊技機本体１の表面からわずかに遊技者側に突出した位置に配され、かつ、光透過型センサ４２の光路はプランジャー体３１の遮光板３２によって遮られた状態となっている。   In the above-described configuration, when the push button member 30 is not pressed, the operation surface 36 that is the surface of the cover body 35 is slightly protruded from the surface of the gaming machine body 1 to the player side. The light path of the light transmission type sensor 42 is blocked by the light blocking plate 32 of the plunger body 31.

次に、押しボタン部材３０の操作態様を説明する。
遊技者が押しボタン部材３０のカバー体３５の操作面３６を押圧すると、プランジャー体３１がベース体２０内に押し込まれ、遮光板３２が光透過型センサ４２の光路から離脱する。 Next, the operation mode of the push button member 30 will be described.
When the player presses the operation surface 36 of the cover body 35 of the push button member 30, the plunger body 31 is pushed into the base body 20 and the light shielding plate 32 is detached from the optical path of the light transmission type sensor 42.

そうすると、光透過型センサ４２がこれを検知し、押しボタン部材３０が押圧操作されたことを示す電気信号を本体基板に送信する。   Then, the light transmission type sensor 42 detects this, and transmits an electric signal indicating that the push button member 30 has been pressed to the main body substrate.

次に、本発明の要部について説明する。
押しボタン部材３０を囲繞するベース体２０の側壁部２１のうち、押しボタン部材３０の境界部３７の一部に少なくとも対向する位置に、導電性を有する基板保護用導電部６０が形成されている。具体的には、基板保護用導電部６０の一部を構成する平板状の側板部６１が、ベース体２０の側壁部２１に配置されている。そして、側板部６１の寸法形状は、押しボタン部材３０の押圧操作に関わらず境界部３７と常時対向するような寸法形状に設定されている。 Next, the main part of the present invention will be described.
An electrically conductive substrate protecting conductive portion 60 is formed at a position facing at least a part of the boundary portion 37 of the push button member 30 in the side wall portion 21 of the base body 20 surrounding the push button member 30. . Specifically, a flat plate-like side plate portion 61 constituting a part of the substrate protecting conductive portion 60 is disposed on the side wall portion 21 of the base body 20. The dimensional shape of the side plate portion 61 is set so as to always face the boundary portion 37 regardless of the pressing operation of the push button member 30.

なお、側板部６１は、図１において左側に位置する側壁部２１の位置にのみ配置されており、以下、側板部６１と対向する境界部３７の部分を導電部側境界部３７ａ（図２，４等参照）として説明し、側板部６１と対向しない境界部３７の部分を非導電部側境界部３７ｂ（図２，４等参照）として説明をする。   The side plate portion 61 is disposed only at the position of the side wall portion 21 located on the left side in FIG. 1, and hereinafter, the portion of the boundary portion 37 facing the side plate portion 61 is defined as the conductive portion side boundary portion 37a (FIG. 2, FIG. 4), and a portion of the boundary portion 37 that does not face the side plate portion 61 will be described as a non-conductive portion side boundary portion 37b (see FIGS. 2 and 4).

さらに、側板部６１には、ベース体２０に設けられた固定用突片２３の一方の側面を被覆する導電性の突片部６２が連続状に形成されている。なお、突片部６２において、固定用突片２３に設けられた固定用孔２２に対応する位置には、ボルト（図示省略）を挿通可能とする孔部６３が設けられている。   Further, the side plate portion 61 is formed with a continuous conductive protrusion 62 that covers one side surface of the fixing protrusion 23 provided on the base body 20. In the protrusion 62, a hole 63 through which a bolt (not shown) can be inserted is provided at a position corresponding to the fixing hole 22 provided in the fixing protrusion 23.

かかる構成にあって、ベース体２０の固定用突片２３に設けられた固定用孔２２に金属製のボルトが挿通されると、上述のように押しボタンユニット体１０Ａ全体が遊技機本体１に固定され、かつ、基板保護用導電部６０が、ボルトを介してアース接続される。   In this configuration, when a metal bolt is inserted into the fixing hole 22 provided in the fixing protrusion 23 of the base body 20, the entire push button unit body 10A is attached to the gaming machine body 1 as described above. The board protecting conductive portion 60 is fixed and grounded via a bolt.

ここで、図４（ａ）に示すように、押しボタン部材３０が押圧されていない状態で、例えば、カバー体３５の操作面３６のうち、基板保護用導電部６０に近い側に静電気が発生した場合、かかる静電気は、矢印Ａに示すようにカバー体３５の側面を流れ、基板保護用導電部６０の側板部６１に誘引される。したがって、静電気の発生によって基板４０が電気的に破壊されることを防止することができる。
ここで、押しボタンユニット体１０Ａにおける静電気の流れは、いわゆる押しボタンユニット体１０Ａ内における沿面距離及び空間距離等に基づいて定まるものである。具体的に説明すると、静電気が発生した位置を基準として、互いに方向が異なる２つの地点があるとき、静電気は、静電気が発生した位置を基準として、電気的な距離が短いほうの地点に向けて流れる。このとき、沿面距離や空間距離が長くなると、電気的な距離はそれに応じて長くなるが、静電気が流れる経路上に金属などの導電性を有する部材がある場合、実用上、導電性を有する部材の寸法は電気的な距離から除外される。 Here, as shown in FIG. 4A, static electricity is generated, for example, on the side of the operation surface 36 of the cover body 35 close to the board protection conductive portion 60 in a state where the push button member 30 is not pressed. In this case, the static electricity flows through the side surface of the cover body 35 as indicated by the arrow A, and is attracted to the side plate portion 61 of the board protecting conductive portion 60. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.
Here, the flow of static electricity in the push button unit body 10A is determined based on the creepage distance and the spatial distance in the so-called push button unit body 10A. Specifically, when there are two points with different directions relative to the position where the static electricity is generated, the static electricity is directed toward the point where the electrical distance is short, based on the position where the static electricity is generated. Flowing. At this time, when the creepage distance or the spatial distance is increased, the electrical distance is increased accordingly. However, when there is a conductive member such as metal on the path through which static electricity flows, the conductive member is practically used. Are excluded from the electrical distance.

ここで、図４（ａ）において、仮に、基板保護用導電部６０が形成されていない場合は、静電気は、矢印Ｂに示すようにカバー体３５の側面及び境界部３７を流れ、さらに、矢印Ｃに示すように、導電性を有する装飾部材５０を介して基板４０に向かって流れてしまう。   Here, in FIG. 4A, if the substrate protecting conductive portion 60 is not formed, the static electricity flows through the side surface and the boundary portion 37 of the cover body 35 as shown by the arrow B, and the arrow As shown to C, it will flow toward the board | substrate 40 through the decoration member 50 which has electroconductivity.

換言すると、基板保護用導電部６０を備えないとすれば、操作面３６にて発生した静電気は、矢印Ｂ及び矢印Ｃで示したように、境界部３７を経由した経路を流れようとする。
しかしながら、押しボタンユニット体１０Ａでは、境界部３７と対向する位置に、基板保護用導電部６０の側板部６１が配置されている。そして、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離（操作面３６と基板保護用導電部６０の側板部６１との最短沿面距離）は、操作面３６と基板４０との電気的な距離（操作面３６と装飾部材５０との最短沿面距離と、装飾部材５０と基板４０との最短の空間距離とを合計した距離）より短くなっている。
このため、境界部３７付近に到達した静電気は、電気的な距離が短い基板保護用導電部６０の側板部６１に誘引されるので、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。
つまり、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離を、操作面３６と基板４０との電気的な距離よりも短くすることで、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。 In other words, if the board protecting conductive portion 60 is not provided, the static electricity generated on the operation surface 36 tends to flow along the path via the boundary portion 37 as indicated by arrows B and C.
However, in the push button unit body 10 </ b> A, the side plate portion 61 of the board protecting conductive portion 60 is disposed at a position facing the boundary portion 37. The electrical distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60 (the shortest creepage distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60) is the operation surface 36 and the substrate. 40 (the total distance of the shortest creepage distance between the operation surface 36 and the decorative member 50 and the shortest spatial distance between the decorative member 50 and the substrate 40).
For this reason, the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the substrate protection conductive portion 60 with a short electrical distance, and thus the static electricity flows toward the substrate 40 through the boundary portion 37. It becomes possible to avoid that.
That is, static electricity passes through the boundary portion 37 by making the electrical distance between the operation surface 36 and the side plate portion 61 of the board protecting conductive portion 60 shorter than the electrical distance between the operation surface 36 and the substrate 40. Thus, it is possible to avoid the flow toward the substrate 40.

これまでに述べたように、押しボタンユニット体１０Ａは、押しボタン部材３０の外側であって境界部３７と対向する位置に基板保護用導電部６０を配置したため、押しボタン部材３０の操作面３６と基板保護用導電部６０との電気的な距離を十分に接近させた設計がし易くなると共に、操作面３６と押しボタン部材３０内にある基板４０との電気的な距離を十分に離間させた設計がし易くなる。したがって、押しボタンユニット１０Ａを可及的にコンパクト化しようとする設計と、基板４０の静電気対策のための設計とを無理なく両立させることが可能となる。   As described above, the push button unit body 10 </ b> A has the board protecting conductive portion 60 disposed at a position outside the push button member 30 and facing the boundary portion 37. The electrical distance between the operation surface 36 and the substrate 40 in the push button member 30 is sufficiently separated from each other. Easy design. Therefore, the design for making the push button unit 10A as compact as possible and the design for countermeasure against static electricity of the substrate 40 can be made compatible with each other.

また、図４（ｂ）に示すように、押しボタン部材３０が押圧されている際にカバー体３５の操作面３６のうち、基板保護用導電部６０に近い側に静電気が発生した場合にも、かかる静電気は、矢印Ｄに示すようにカバー体３５の側面を流れ、基板保護用導電部６０の側板部６１に誘引される。したがって、静電気の発生によって基板４０が電気的に破壊されることを防止することができる。   Also, as shown in FIG. 4B, when static electricity is generated on the side of the operation surface 36 of the cover body 35 close to the board protecting conductive portion 60 when the push button member 30 is pressed. Such static electricity flows through the side surface of the cover body 35 as indicated by the arrow D, and is attracted to the side plate portion 61 of the conductive portion 60 for substrate protection. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

ここで、仮に、基板保護用導電部６０が形成されていない場合は、静電気は、矢印Ｅに示すようにカバー体３５の側面及び境界部３７を流れ、さらに、矢印Ｆに示すように、装飾部材５０を介して基板４０に向かって流れてしまう。   Here, if the substrate protection conductive portion 60 is not formed, static electricity flows through the side surface and the boundary portion 37 of the cover body 35 as indicated by an arrow E, and further, as indicated by an arrow F, the decoration is applied. It flows toward the substrate 40 via the member 50.

換言すると、操作面３６にて発生した静電気は、矢印Ｅ及び矢印Ｆで示すように、境界部３７を経由する経路を流れようとするが、押しボタンユニット体１０Ａでは、押しボタン部材３０が押圧されている状態における境界部３７の位置と対向する位置に、基板保護用導電部６０の側板部６１が配置されている。そして、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離（操作面３６と基板保護用導電部６０の側板部６１との最短沿面距離）は、操作面３６と基板４０との電気的な距離（操作面３６と装飾部材５０との最短沿面距離と、装飾部材５０と基板４０との最短の空間距離とを合計した距離）より短くなっている。
このため、境界部３７付近に到達した静電気は、押しボタン部材３０が押圧されている状態においても、電気的な距離が短い基板保護用導電部６０の側板部６１に誘引されるので、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。
つまり、押しボタン部材３０が押圧されている状態においても、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離を、操作面３６と基板４０との電気的な距離より短くすることで、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。 In other words, as shown by arrows E and F, the static electricity generated on the operation surface 36 tends to flow along a route passing through the boundary portion 37. However, in the push button unit body 10A, the push button member 30 is pressed. The side plate portion 61 of the board protection conductive portion 60 is disposed at a position opposite to the position of the boundary portion 37 in the state where the substrate protection is performed. The electrical distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60 (the shortest creepage distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60) is the operation surface 36 and the substrate. 40 (the total distance of the shortest creepage distance between the operation surface 36 and the decorative member 50 and the shortest spatial distance between the decorative member 50 and the substrate 40).
For this reason, since the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the board protection conductive portion 60 with a short electrical distance even when the push button member 30 is being pressed, It is possible to avoid flowing toward the substrate 40 through the boundary portion 37.
That is, even in the state where the push button member 30 is pressed, the electrical distance between the operation surface 36 and the side plate portion 61 of the conductive portion 60 for protecting the substrate is greater than the electrical distance between the operation surface 36 and the substrate 40. By shortening, it becomes possible to avoid that static electricity flows toward the board | substrate 40 through the boundary part 37. FIG.

また、図５（ａ）に示すように、押しボタン部材３０が押圧されていない状態で、例えば、カバー体３５の操作面３６のうち、基板保護用導電部６０から遠い位置で静電気が発生した場合、かかる静電気は、矢印Ｇに示すようにカバー体３５の側面を流れ、次いで非導電部側境界部３７ｂを介して押しボタン部材３０内に侵入し、導電性を有する装飾部材５０の表面を流れて、導電部側境界部３７ａを介して矢印Ｈに示すように基板保護用導電部６０の側板部６１に誘引される。
換言すると、非導電部側境界部３７ｂの周辺で発生した静電気は、非導電部側境界部３７ｂを介して押しボタン部材３０内に侵入し、矢印Ｚ１で示すように導電性を有する装飾部材５０の表面を介して基板４０に向かって流れることや、矢印Ｚ２で示すようにプランジャー体３１の基板収容空間Ｙ側の表面を介して基板４０に向かって流れることが考えられる。
しかしながら、押しボタンユニット体１０Ａでは、導電部側境界部３７ａと対向し、かつ、非導電部側境界部３７ｂにも対向する位置に、導電性を有する表面を備える装飾部材５０が配置されている。そして、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂと基板４０との電気的な距離よりも短くなっている。
具体的に説明すると、非導電部側境界部３７ｂと基板４０との電気的な距離は、矢印Ｚ１で示す経路で静電気が流れるときは、非導電部側境界部３７ｂと装飾部材５０の表面との最短沿面距離と、装飾部材５０の表面と基板４０との最短の空間距離とを合計した距離となり、矢印Ｚ２で示す経路で静電気が流れるときは、プランジャー体３１の基板収容空間Ｙ側の表面を経由した非導電部側境界部３７ｂと基板４０との最短沿面距離となる。
一方、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、経路上にある装飾部材５０の表面が導電性を有するので電気的な距離から除外されるため、非導電部側境界部３７ｂと基板４０との電気的な距離に比べて、短くすることができる。
具体的には、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂから装飾部材５０の非導電部側境界部３７ｂと対向する端部までの距離と、装飾部材５０の導電部側境界部３７ａと対向する端部から導電部側境界部３７ａを経て基板保護用導電部６０の側板部６１に至るまでの距離とを合計した距離となる。
このため、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との実際の距離に比べて、実際の距離の大部分を占める装飾部材５０の寸法が除外されるため、短くなる。
これにより、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離が、非導電部側境界部３７ｂと基板４０との電気的な距離よりも、短くなるように、基板４０を配置することができる。
そして、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離を、非導電部側境界部３７ｂと基板４０との電気的な距離よりも短くすることで、基板保護用導電部６０と対向しない非導電部側境界部３７ｂの周辺に静電気が帯電した場合に、装飾部材５０を介して基板保護用導電部６０に静電気を適切に誘引することができる。
したがって、かかる場合にも、静電気の発生によって基板４０が電気的に破壊されることを防止することができる。 As shown in FIG. 5A, static electricity is generated, for example, at a position far from the board protecting conductive portion 60 in the operation surface 36 of the cover body 35 in a state where the push button member 30 is not pressed. In this case, the static electricity flows through the side surface of the cover body 35 as indicated by an arrow G, and then enters the push button member 30 via the non-conductive portion side boundary portion 37b, and the surface of the decorative member 50 having conductivity is formed. It flows and is attracted to the side plate portion 61 of the substrate protection conductive portion 60 through the conductive portion side boundary portion 37a as indicated by an arrow H.
In other words, static electricity generated around the non-conductive portion side boundary portion 37b enters the push button member 30 through the non-conductive portion side boundary portion 37b, and has a conductive decorative member 50 as indicated by an arrow Z1. It is conceivable that the air flows toward the substrate 40 via the surface of the plunger body 31 or flows toward the substrate 40 via the surface of the plunger body 31 on the substrate accommodating space Y side as indicated by an arrow Z2.
However, in the push button unit body 10A, the decorative member 50 having a conductive surface is disposed at a position facing the conductive portion side boundary portion 37a and also facing the nonconductive portion side boundary portion 37b. . The electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is shorter than the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40. .
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40 is such that when static electricity flows through the path indicated by the arrow Z1, the non-conductive portion side boundary portion 37b and the surface of the decorative member 50 are When the static electricity flows through the path indicated by the arrow Z2, the distance between the shortest creepage distance and the shortest spatial distance between the surface of the decorative member 50 and the substrate 40 is the distance on the substrate housing space Y side of the plunger body 31. This is the shortest creepage distance between the non-conductive portion side boundary portion 37b and the substrate 40 via the surface.
On the other hand, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is excluded from the electrical distance because the surface of the decorative member 50 on the path has conductivity. Therefore, the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40 can be shortened.
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is such that the non-conductive portion side boundary portion 37b of the decorative member 50 is separated from the non-conductive portion side boundary portion 37b. And the distance from the end portion of the decorative member 50 facing the conductive portion side boundary portion 37a to the side plate portion 61 of the conductive portion 60 for substrate protection through the conductive portion side boundary portion 37a Is the total distance.
Therefore, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the actual distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60. The dimension of the decorative member 50 occupying most of the actual distance is excluded from the distance, and thus becomes shorter.
Thereby, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is shorter than the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40. Thus, the substrate 40 can be arranged.
The electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is made shorter than the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40. When static electricity is charged around the non-conductive portion side boundary portion 37 b that does not face the conductive portion for substrate protection 60, the static electricity can be appropriately attracted to the conductive portion for substrate protection 60 through the decorative member 50.
Therefore, even in such a case, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

これまでに述べたように、押しボタンユニット体１０Ａは、押しボタン部材３０の外側であって境界部３７と対向する位置に基板保護用導電部６０を配置したため、押しボタン部材３０の操作面３６と基板保護用導電部６０との電気的な距離を、装飾部材５０を導電路として有効に利用しつつ十分に接近させた設計がし易くなると共に、操作面３６と押しボタン部材３０内にある基板４０との電気的な距離を十分に離間させた設計がし易くなる。したがって、装飾部材５０が内蔵された状態で押しボタンユニット１０Ａを可及的にコンパクト化しようとする設計と、基板４０の静電気対策のための設計とを無理なく両立させることが可能となる。   As described above, the push button unit body 10 </ b> A has the board protecting conductive portion 60 disposed at a position outside the push button member 30 and facing the boundary portion 37. It is easy to design the electrical distance between the conductive portion 60 for protecting the board and the board protecting conductive portion 60 sufficiently while effectively using the decorative member 50 as a conductive path, and it is within the operation surface 36 and the push button member 30. It is easy to design with a sufficient electrical distance from the substrate 40. Therefore, the design for making the push button unit 10A as compact as possible with the decorative member 50 incorporated therein and the design for the countermeasure against static electricity of the substrate 40 can be made compatible with each other.

また、図５（ｂ）に示すように、押しボタン部材３０が押圧されている際に、例えば、カバー体３５の操作面３６のうち、基板保護用導電部６０から遠い位置で静電気が発生した場合にも、かかる静電気は、矢印Ｊに示すようにカバー体３５の側面を流れ、次いで非導電部側境界部３７ｂを介して押しボタン部材３０内に侵入し、かつ装飾部材５０の表面を流れて、矢印Ｋに示すように導電部側境界部３７ａを介して基板保護用導電部６０の側板部６１に誘引される。
換言すると、非導電部側境界部３７ｂの周辺で発生した静電気は、非導電部側境界部３７ｂを介して押しボタン部材３０内に侵入し、矢印Ｚ３で示すように導電性を有する装飾部材５０を介して基板４０に向かって流れることや、矢印Ｚ４で示すようにプランジャー体３１の基板収容空間Ｙ側の表面を介して基板４０に向かって流れることが考えられる。
しかしながら、押しボタンユニット体１０Ａでは、押しボタン部材３０が押圧されている状態において、導電部側境界部３７ａと対向し、かつ、非導電部側境界部３７ｂと対向する位置に、導電性を有する表面を備える装飾部材５０が配置されており、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂと基板４０との電気的な距離よりも短くなっている。
具体的に説明すると、非導電部側境界部３７ｂと基板４０との電気的な距離は、矢印Ｚ３で示す経路で静電気が流れるときは、非導電部側境界部３７ｂと装飾部材５０との最短沿面距離と、装飾部材５０と基板４０との最短の空間距離とを合計した距離となり、矢印Ｚ４で示す経路で静電気が流れるときは、プランジャー体３１の基板収容空間Ｙ側の表面を経由した非導電部側境界部３７ｂと基板４０との最短沿面距離となる。
一方、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、経路上にある装飾部材５０が導電性を有するので電気的な距離から除外されるため、非導電部側境界部３７ｂと基板４０との距離に比べて、短くすることができる。
具体的には、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂから装飾部材５０の非導電部側境界部３７ｂと対向する端部までの距離と、装飾部材５０の導電部側境界部３７ａと対向する端部から導電部側境界部３７ａを経て基板保護用導電部６０の側板部６１に至るまでの距離とを合計した距離となる。
このため、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との実際の距離に比べて、実際の距離の大部分を占める装飾部材５０の寸法が除外されるため、短くなる。
これにより、押しボタン部材３０が押圧されている状態においても、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂと基板４０との電気的な距離よりも短くなっている。
そして、押しボタン部材３０が押圧されている状態においても、非導電部側境界部３７ｂと基板保護用導電部６０の側板部６１との電気的な距離は、非導電部側境界部３７ｂと基板４０との電気的な距離よりも短いため、基板保護用導電部６０と対向しない非導電部側境界部３７ｂの周辺に静電気が帯電した場合に、装飾部材５０を介して基板保護用導電部６０に静電気を適切に誘引することができる。
したがって、かかる場合にも、静電気の発生によって基板４０が電気的に破壊されることを防止することができる。 Further, as shown in FIG. 5B, when the push button member 30 is pressed, for example, static electricity is generated at a position far from the board protecting conductive portion 60 in the operation surface 36 of the cover body 35. Even in such a case, the static electricity flows on the side surface of the cover body 35 as indicated by an arrow J, and then enters the push button member 30 via the non-conductive portion side boundary portion 37b and flows on the surface of the decorative member 50. Then, as shown by an arrow K, the side plate portion 61 of the substrate protecting conductive portion 60 is attracted via the conductive portion side boundary portion 37a.
In other words, static electricity generated around the non-conductive portion side boundary portion 37b enters the push button member 30 through the non-conductive portion side boundary portion 37b, and has a conductive decorative member 50 as indicated by an arrow Z3. It is conceivable that the gas flows toward the substrate 40 through the surface, or flows toward the substrate 40 through the surface of the plunger body 31 on the substrate accommodating space Y side as indicated by an arrow Z4.
However, in the push button unit body 10A, in a state in which the push button member 30 is pressed, the push button unit body 10A has conductivity at a position facing the conductive portion side boundary portion 37a and facing the nonconductive portion side boundary portion 37b. A decorative member 50 having a surface is arranged, and the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the non-conductive portion side boundary portion 37b and the substrate 40. It is shorter than the electrical distance.
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40 is the shortest distance between the non-conductive portion side boundary portion 37b and the decorative member 50 when static electricity flows along the path indicated by the arrow Z3. When the static electricity flows along the path indicated by the arrow Z4, the creepage distance and the shortest spatial distance between the decorative member 50 and the substrate 40 are combined, and the surface of the plunger body 31 passes through the surface on the substrate accommodation space Y side. This is the shortest creepage distance between the non-conductive portion side boundary portion 37b and the substrate 40.
On the other hand, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is excluded from the electrical distance because the decorative member 50 on the path has conductivity. The distance between the non-conductive portion side boundary portion 37b and the substrate 40 can be shortened.
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is such that the non-conductive portion side boundary portion 37b of the decorative member 50 is separated from the non-conductive portion side boundary portion 37b. And the distance from the end portion of the decorative member 50 facing the conductive portion side boundary portion 37a to the side plate portion 61 of the conductive portion 60 for substrate protection through the conductive portion side boundary portion 37a Is the total distance.
Therefore, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the actual distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60. The dimension of the decorative member 50 occupying most of the actual distance is excluded from the distance, and thus becomes shorter.
Thereby, even in the state where the push button member 30 is pressed, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is the same as the non-conductive portion side boundary portion 37b. The electrical distance from the substrate 40 is shorter.
Even in the state in which the push button member 30 is pressed, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the non-conductive portion side boundary portion 37b and the substrate. When the static electricity is charged around the non-conductive portion side boundary portion 37 b that is not opposed to the substrate-protecting conductive portion 60 because it is shorter than the electrical distance to 40, the substrate-protecting conductive portion 60 is interposed via the decorative member 50. It is possible to attract static electricity appropriately.
Therefore, even in such a case, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

なお、基板保護用導電部６０の側板部６１は、ベース体２０の側壁部２１において押しボタン部材３０と離間して配置されており、かつ、基板保護用導電部６０は押しボタン部材３０の押圧操作の有無に関わらず位置が変わらないため、押しボタンユニット体１０Ａは全体として構造が複雑化せず、部品等にクラック等が発生して静電気対策が維持できなくなる、といったことが抑制されている。
また、静電気対策が既になされたユニット構造となり、遊技機本体１への取付け作業と静電気対策のための作業が共に簡便となる。加えて、基板保護用導電部６０は、遊技者側から隠れて見えないため、美観に優れている。 The side plate portion 61 of the board protecting conductive portion 60 is disposed on the side wall portion 21 of the base body 20 so as to be separated from the push button member 30, and the substrate protecting conductive portion 60 is pressed by the push button member 30. Since the position does not change regardless of the presence or absence of the operation, the structure of the push button unit 10A is not complicated as a whole, and it is suppressed that the countermeasure against static electricity cannot be maintained due to the occurrence of cracks or the like in the parts. .
In addition, the unit structure has already been provided with countermeasures against static electricity, and both the mounting work to the gaming machine body 1 and the work for countermeasures against static electricity are simplified. In addition, since the board protecting conductive portion 60 is hidden from the player side and cannot be seen, it is excellent in aesthetics.

さらに、押しボタンユニット体１０Ａは、押しボタン部材３０内に、遊技者の関心を惹く装飾部材５０がコンパクトに配置されているため、押しボタンユニット体１０Ａ全体の厚みを薄くすることができ、かつ、スロットマシンの意匠性を向上させることができる。
また、仮に基板保護用導電部６０と対向しない非導電部側境界部３７ｂの周辺に静電気が帯電した場合にも、装飾部材５０を介して基板保護用導電部６０に静電気を適切に誘引することができる。 Furthermore, since the decorative member 50 that attracts the player's interest is compactly arranged in the push button member 30 in the push button unit body 10A, the thickness of the entire push button unit body 10A can be reduced, and The design of the slot machine can be improved.
Further, even when static electricity is charged around the non-conductive portion side boundary portion 37 b that does not face the conductive portion 60 for protecting the substrate, the static electricity is appropriately attracted to the conductive portion 60 for protecting the substrate through the decorative member 50. Can do.

〔実施例２〕
実施例２の押しボタンユニット体１０Ｂを図６に従って説明する。なお、押しボタンユニット体１０Ｂは、装飾部材５０が配置されていない以外は上記実施例１の押しボタンユニット体１０Ａと同様の構成を有しているため、同じ構成を有するものには同じ符号を付し、説明を省略する。 [Example 2]
A push button unit body 10B according to the second embodiment will be described with reference to FIG. Since the push button unit body 10B has the same configuration as the push button unit body 10A of the first embodiment except that the decorative member 50 is not disposed, the same reference numerals are given to those having the same configuration. The description is omitted.

図６（ａ）に示すように、押しボタン部材３０が押圧されていない状態で、例えばカバー体３５の操作面３６のうち、基板保護用導電部６０に近い側で静電気が発生した場合、かかる静電気は、矢印Ｎに示すようにカバー体３５の側面を流れ、基板保護用導電部６０の側板部６１に誘引される。したがって、静電気の発生によって基板４０が電気的に破壊されることを防止することができる。   As shown in FIG. 6A, in the state where the push button member 30 is not pressed, for example, when static electricity is generated on the side of the operation surface 36 of the cover body 35 that is close to the conductive portion 60 for protecting the substrate, this occurs. The static electricity flows through the side surface of the cover body 35 as indicated by an arrow N, and is attracted to the side plate portion 61 of the board protecting conductive portion 60. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

ここで、仮に、基板保護用導電部６０が形成されていない場合は、静電気が矢印Ｐに示すようにカバー体３５の側面を流れ、さらに、境界部３７を介して基板４０に向かって静電気が流れてしまう。   Here, if the substrate protection conductive portion 60 is not formed, static electricity flows through the side surface of the cover body 35 as indicated by the arrow P, and further, static electricity flows toward the substrate 40 via the boundary portion 37. It will flow.

換言すると、操作面３６にて発生した静電気は、矢印Ｐで示ように、境界部３７を経由する経路を流れようとするが、押しボタンユニット体１０Ｂでは、境界部３７と対向する位置に、基板保護用導電部６０の側板部６１が配置されており、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離（操作面３６と基板保護用導電部６０の側板部６１との最短沿面距離）は、操作面３６と基板４０との電気的な距離（操作面３６と基板４０との最短沿面距離）よりも短い。
このため、境界部３７付近に到達した静電気は、電気的な距離が短い基板保護用導電部６０の側板部６１に誘引されるので、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。
つまり、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離を、操作面３６と基板４０との電気的な距離よりも短くすることで、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。 In other words, the static electricity generated on the operation surface 36 tends to flow along a route passing through the boundary portion 37 as indicated by an arrow P, but in the push button unit body 10B, at a position facing the boundary portion 37, The side plate portion 61 of the substrate protection conductive portion 60 is disposed, and the electrical distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60 (the operation plate 36 and the side plate portion of the substrate protection conductive portion 60). 61 is shorter than the electrical distance between the operation surface 36 and the substrate 40 (the shortest creepage distance between the operation surface 36 and the substrate 40).
For this reason, the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the substrate protection conductive portion 60 with a short electrical distance, and thus the static electricity flows toward the substrate 40 through the boundary portion 37. It becomes possible to avoid that.
That is, static electricity passes through the boundary portion 37 by making the electrical distance between the operation surface 36 and the side plate portion 61 of the board protecting conductive portion 60 shorter than the electrical distance between the operation surface 36 and the substrate 40. Thus, it is possible to avoid the flow toward the substrate 40.

これまでに述べたように、押しボタンユニット体１０Ｂは、押しボタン部材３０の外側であって境界部３７と対向する位置に基板保護用導電部６０を配置したため、押しボタン部材３０の操作面３６と基板保護用導電部６０との電気的な距離を十分に接近させた設計がし易くなると共に、操作面３６と押しボタン部材３０内にある基板４０との電気的な距離を十分に離間させた設計がし易くなる。したがって、押しボタンユニット１０Ｂを可及的にコンパクト化しようとする設計と、基板４０の静電気対策のための設計とを無理なく両立させることが可能となる。   As described above, the push button unit body 10 </ b> B has the board protecting conductive portion 60 disposed at a position facing the boundary portion 37 outside the push button member 30. The electrical distance between the operation surface 36 and the substrate 40 in the push button member 30 is sufficiently separated from each other. Easy design. Therefore, the design for making the push button unit 10B as compact as possible and the design for countermeasure against static electricity of the substrate 40 can be made compatible with each other.

また、図６（ｂ）に示すように、押しボタン部材３０が押圧されている際にカバー体３５の操作面３６のうち、基板保護用導電部６０に近い側で静電気が発生した場合にも、かかる静電気は、矢印Ｑに示すようにカバー体３５の側面を流れ、基板保護用導電部６０の側板部６１に誘引される。したがって、静電気の発生によって基板４０が電気的に破壊されることを防止することができる。   Also, as shown in FIG. 6B, when static electricity is generated on the side of the operation surface 36 of the cover body 35 close to the board protection conductive portion 60 when the push button member 30 is pressed. Such static electricity flows through the side surface of the cover body 35 as indicated by an arrow Q, and is attracted to the side plate portion 61 of the board protecting conductive portion 60. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

ここで、仮に、基板保護用導電部６０が形成されていない場合は、静電気が矢印Ｒに示すようにカバー体３５の側面を流れ、さらに、境界部３７を介して基板４０に向かって電気が流れてしまう。   Here, if the substrate protection conductive portion 60 is not formed, static electricity flows through the side surface of the cover body 35 as indicated by the arrow R, and further, electricity flows toward the substrate 40 via the boundary portion 37. It will flow.

換言すると、操作面３６にて発生した静電気は、矢印Ｒで示ように、境界部３７を経由する経路を流れようとするが、押しボタンユニット体１０Ｂでは、押しボタン部材３０が押圧されている状態における境界部３７の位置と対向する位置に、基板保護用導電部６０の側板部６１が配置されており、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離（操作面３６と基板保護用導電部６０の側板部６１との最短沿面距離）は、操作面３６と基板４０との電気的な距離（操作面３６と基板４０との最短沿面距離）よりも短いため、境界部３７付近に到達した静電気は、押しボタン部材３０が押圧されている状態においても、電気的な距離が短い基板保護用導電部６０の側板部６１に誘引されるので、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。
つまり、押しボタン部材３０が押圧されている状態においても、操作面３６と基板保護用導電部６０の側板部６１との電気的な距離を、操作面３６と基板４０との電気的な距離よりも短くすることで、押しボタン部材３０が押圧されている状態においても、静電気が境界部３７を介して基板４０に向かって流れてしまうことを回避することが可能となる。 In other words, the static electricity generated on the operation surface 36 tends to flow along a route passing through the boundary portion 37 as indicated by the arrow R, but the push button member 30 is pressed in the push button unit body 10B. The side plate portion 61 of the substrate protecting conductive portion 60 is disposed at a position opposite to the position of the boundary portion 37 in the state, and the electrical distance (the distance between the operation surface 36 and the side plate portion 61 of the substrate protecting conductive portion 60 ( The shortest creepage distance between the operation surface 36 and the side plate portion 61 of the substrate protecting conductive portion 60 is shorter than the electrical distance between the operation surface 36 and the substrate 40 (the shortest creepage distance between the operation surface 36 and the substrate 40). Therefore, since the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the board protection conductive portion 60 having a short electrical distance even when the push button member 30 is pressed, the static electricity is bounded by the boundary. Via part 37 It is possible to avoid that may flow towards the plate 40.
That is, even in the state where the push button member 30 is pressed, the electrical distance between the operation surface 36 and the side plate portion 61 of the conductive portion 60 for protecting the substrate is greater than the electrical distance between the operation surface 36 and the substrate 40. By shortening the length, it is possible to prevent static electricity from flowing toward the substrate 40 via the boundary portion 37 even when the push button member 30 is pressed.

なお、上記実施例にあっては、押しボタンユニット体１０Ａ，１０Ｂの各部材の形状寸法は適宜自由に選択可能である。   In addition, in the said Example, the shape dimension of each member of pushbutton unit body 10A, 10B can be freely selected suitably.

また、例えば、カバー体３５は、全体が透明性を有する構成であってもよいし、透明性を有する部分が一部形成されている構成であってもよい。   Further, for example, the cover body 35 may have a configuration having transparency as a whole, or may have a configuration in which a portion having transparency is partially formed.

なお、基板保護用導電部６０は、押しボタン部材３０が押圧されたときのみ境界部３７と対向してもよいし、押しボタン部材３０が押圧されていないときにのみ境界部３７と対向してもよい。   The board protecting conductive portion 60 may face the boundary portion 37 only when the push button member 30 is pressed, or face the boundary portion 37 only when the push button member 30 is not pressed. Also good.

また、基板保護用導電部６０は、境界部３７の少なくとも一部に対向する位置に配置されていればよく、部分的に対向していない箇所があっても構わない。
また、基板保護用導電部６０が、境界部３７と全周にわたって対向するように形成されている構成であってもよい。 Moreover, the board | substrate protective electroconductive part 60 should just be arrange | positioned in the position which opposes at least one part of the boundary part 37, and may have the location which is not partially opposed.
Moreover, the structure currently formed so that the board | substrate protection electroconductive part 60 may oppose the boundary part 37 over a perimeter may be sufficient.

また、装飾部材５０は、表面のみ導電性を有している必要はなく、全体が導電性材料によって形成されていても構わない。   Moreover, the decoration member 50 does not need to have electroconductivity only in the surface, and the whole may be formed with the electroconductive material.

さらに、装飾部材５０の周縁部が、境界部３７と全周にわたって対向するような構成であってもよいし、基板保護用導電部６０と対向する導電部側境界部３７ａのうち一部と装飾部材５０の一部とが対向し、かつ、基板保護用導電部６０と対向しない非導電部側境界部３７ｂの一部と装飾部材５０の他の一部とが対向している構成であってもよい。   Furthermore, the configuration may be such that the peripheral portion of the decorative member 50 faces the boundary portion 37 over the entire circumference, and a part of the conductive portion side boundary portion 37a that faces the board protecting conductive portion 60 is decorated. A part of the member 50 is opposed, and a part of the non-conductive part side boundary part 37b that is not opposed to the board protecting conductive part 60 is opposed to another part of the decorative member 50. Also good.

また、基板４０は、押しボタン部材３０の作動と関連する回路を有していてもよいし、押しボタン部材３０の作動と関連しない回路を有していてもよい。具体的に押しボタン部材３０の作動と関連する回路としては、押しボタン部材３０の押圧操作に基づいて押しボタン部材３０の押圧状態又は非押圧状態を検知する回路が例示される。また、具体的に押しボタン部材３０の作動と関連しない回路としては、ＬＥＤ素子４３によって押しボタン部材３０内を照らして演出的な発光態様を提供するための回路が例示される。   The substrate 40 may have a circuit related to the operation of the push button member 30 or may have a circuit not related to the operation of the push button member 30. Specifically, the circuit related to the operation of the push button member 30 is exemplified by a circuit that detects a pressed state or a non-pressed state of the push button member 30 based on a pressing operation of the push button member 30. Further, as a circuit that is not specifically related to the operation of the push button member 30, a circuit for illuminating the inside of the push button member 30 by the LED element 43 and providing a stunning light emission mode is exemplified.
