Description
本発明は、遊技機本体に対し前面扉がヒンジ機構を介して開閉可能に軸支された遊技機に係り、特に、前面扉が自重で下方にへたるのを防止する垂れ防止構造に関するものである。 The present invention relates to a gaming machine in which a front door is pivotally supported so as to be openable and closable via a hinge mechanism with respect to a gaming machine body, and more particularly to a sag prevention structure that prevents the front door from falling downward due to its own weight. is there.
遊技機の一例であるパチンコ機は、遊技場の島設備に設置される縦長方形状の機枠と、この機枠にヒンジを介して扉状に開閉可能に取り付けられた本体枠(遊技機本体)と、この本体枠の前面に別のヒンジを介して開閉可能に取り付けられた前面扉とを備えており、本体枠の内側には遊技盤や発射装置等が収容されている。遊技盤はガイドレール等によって区画形成された遊技領域を有しており、この遊技領域には可変表示装置や始動入賞口、一般入賞口、アタッカー装置、遊技釘、風車、アウト口等が設けられている。本体枠の前面には前面扉の開放端(反ヒンジ側)を施錠/開錠する施錠装置が設けられており、常態では、本体枠に対して前面扉の開放端は施錠されている。前面扉の中央部には遊技盤の盤面を臨む開口が設けられており、この開口は透明板によって塞がれている。また、前面扉には開口を包囲するように電飾部品やスピーカ等の演出装置が設けられており、前面扉の下部には遊技球を収容する受皿や発射装置の発射強度を調整する操作ハンドル等が設けられている。 A pachinko machine, which is an example of a gaming machine, is a vertical rectangular machine frame installed on an island facility in a game arcade, and a main body frame (a gaming machine main body) attached to this machine frame in a door-like manner via a hinge. And a front door attached to the front face of the main body frame via another hinge so as to be openable and closable. A game board, a launching device and the like are accommodated inside the main body frame. The game board has a game area defined by guide rails and the like, and this game area is provided with a variable display device, a start winning port, a general winning port, an attacker device, a game nail, a windmill, an out port, etc. ing. A locking device that locks / unlocks the open end (on the anti-hinge side) of the front door is provided on the front face of the main body frame. Normally, the open end of the front door is locked with respect to the main body frame. An opening facing the board surface of the game board is provided at the center of the front door, and this opening is closed by a transparent plate. In addition, the front door is provided with an effect device such as an electric decoration part and a speaker so as to surround the opening, and a lower part of the front door is a receiving tray for storing a game ball and an operation handle for adjusting the firing strength of the launching device. Etc. are provided.
このように概略構成されたパチンコ機では、通常、本体枠が機枠に対して閉じられていると共に、前面扉も本体枠に対して閉じられているため、何人も内部の遊技盤や電子機器等に触れることができないようになっている。ただし、遊技盤に発生した球詰まり等を解消するために前面扉を開放することがあり、その場合、前面扉はヒンジを中心に本体枠に対して回動する。ここで、前面扉には演出装置や操作ハンドル等の各種部品が設けられているため、前面扉の総重量がかなり大きなものになることがあり、そのような場合は、前面扉の反ヒンジ側が経年的に下方へ下がる「へたり」という現象を生じ易くなる。 In the pachinko machine schematically configured in this way, the main body frame is usually closed with respect to the machine frame, and the front door is also closed with respect to the main body frame. It is impossible to touch etc. However, the front door may be opened in order to eliminate ball clogging or the like that has occurred on the game board. In this case, the front door rotates about the hinge with respect to the main body frame. Here, since the front door is equipped with various parts such as a production device and an operation handle, the total weight of the front door may become quite large. In such a case, the anti-hinge side of the front door The phenomenon of “sagging” that falls downward with time is likely to occur.
そこで、従来より、前面扉の反ヒンジ側の背面にL字型金具からなる差し込み部材を取り付けると共に、遊技機本体の前面に断面L字型の受け部材を取り付け、前面扉の閉鎖時に差し込み部材の水平方向に延びる突出片を受け部材の支持板上に当接させることにより、前面扉の反ヒンジ側が自重で下方へ下がらないようにした遊技機(スロットマシン)が提案されている(例えば、特許文献1参照)。かかる従来技術では、開放状態の前面扉を遊技機本体に対して閉じていくと、差し込み部材の突出片が支持板の上面を摺動しながら受け部材の奥側へと導かれるため、前面扉の反ヒンジ側に作用する下方への動きが受け部材によって規制され、前面扉が自重で下方へ垂れてしまうことを防止することができる。 Therefore, conventionally, an insertion member made of an L-shaped bracket is attached to the back surface of the front door on the side opposite to the hinge, and an L-shaped receiving member is attached to the front surface of the gaming machine main body. A gaming machine (slot machine) has been proposed in which a protruding piece extending in a horizontal direction is brought into contact with a support plate of a member so that the anti-hinge side of the front door does not fall downward due to its own weight (for example, a patent) Reference 1). In such a conventional technique, when the front door in the open state is closed with respect to the gaming machine body, the protruding piece of the insertion member is guided to the back side of the receiving member while sliding on the upper surface of the support plate. The downward movement acting on the anti-hinge side is restricted by the receiving member, and the front door can be prevented from drooping downward due to its own weight.
ところで、特許文献1に開示された従来技術では、前面扉の背面側に取り付けられた差し込み部材と遊技機本体の前面側に取り付けられた受け部材とが両方とも金属材料からなるため、前面扉を遊技機本体に対して繰り返し開閉動作すると、差し込み部材と受け部材の金属同士の摩擦によって両者の摺動箇所が比較的短期間で摩耗してしまい、その結果生じる摺動面の荒れや摩耗粉に起因して前面扉をスムーズに開閉しにくくなるという問題がある。なお、差し込み部材と受け部材が金属同士の摺動になるのを避けるために、差し込み部材と受け部材のいずれか一方または両方を合成樹脂の成形品とすることも考えられるが、その場合、静電気を外部に逃がすためのアース構造が煩雑になるという別の問題が発生する。 By the way, in the prior art disclosed by patent document 1, since the insertion member attached to the back side of the front door and the receiving member attached to the front side of the gaming machine main body are both made of a metal material, If the opening / closing operation is repeated with respect to the main body of the gaming machine, the sliding parts of the insertion member and the receiving member are worn in a relatively short period of time due to the friction between the metal of the insertion member and the receiving member. As a result, there is a problem that it is difficult to smoothly open and close the front door. In order to prevent the insertion member and the receiving member from sliding on each other, it is possible to use either one or both of the insertion member and the receiving member as a synthetic resin molded product. Another problem arises in that the grounding structure for escaping to the outside becomes complicated.
すなわち、一般的に前面扉の外装体は絶縁性の合成樹脂で成形され、このような外装体の内部に静電気の影響を受け易い種々の電機部品が収納されている関係上、前面扉に発生または帯電した静電気を所望の導電経路を介して遊技機本体側にアースする必要がある。ただし、前面扉はヒンジ機構を介して遊技機本体に開閉可能に軸支されており、前面扉が遊技機本体に対峙するのは閉鎖時だけであるため、上記したように差し込み部材と受け部材の少なくとも一方を合成樹脂で成形した場合、前面扉に設けた導電板等に接続したリード線をヒンジを経由して遊技機本体のグランド端子に接続しなければならず、かかるリード線の引き回しによってスペース効率が悪化したりメンテナンス作業が煩雑になるという問題が発生する。 That is, the exterior body of the front door is generally formed of an insulating synthetic resin, and various electrical parts that are susceptible to static electricity are housed inside such an exterior body. Alternatively, it is necessary to ground the charged static electricity to the gaming machine main body side through a desired conductive path. However, since the front door is pivotally supported by the gaming machine main body via a hinge mechanism so that the front door faces the gaming machine main body only when it is closed, as described above, the insertion member and the receiving member When at least one of these is molded with synthetic resin, the lead wire connected to the conductive plate or the like provided on the front door must be connected to the ground terminal of the gaming machine body via the hinge. There arises a problem that space efficiency deteriorates and maintenance work becomes complicated.
本発明は、このような従来技術の実情に鑑みてなされたもので、その目的は、アース構造を簡素化できると共に前面扉の自重による垂れを防止しつつ開閉動作をスムーズに行う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 view of the actual situation of the prior art, and an object of the present invention is to simplify the grounding structure and to smoothly perform opening and closing operations while preventing the front door from drooping due to its own weight. Is to provide a machine.
上記の目的を達成するために、本発明は、下部前面側に受け部材が設けられた遊技機本体と、下部背面側に垂れ防止部材が設けられた前面扉とを備え、前記前面扉が前記遊技機本体の前方にヒンジ機構を介して開閉可能に軸支されると共に、この前面扉の閉鎖時に前記垂れ防止部材が前記受け部材に支持されるようになっている遊技機において、前記垂れ防止部材が突出部を有する合成樹脂製の差し込み体と接触片を有する金属製の板ばねとで構成され、前記接触片を前記突出部の底面に設けた開口から下方へ突出させると共に、前記受け部材がグランドに接続された板金製の接地板からなり、前記前面扉の閉鎖時に、前記突出部の下面を前記接地板上に当接させると共に、前記接触片を前記接地板上に弾接させるようにした。 In order to achieve the above object, the present invention comprises a gaming machine main body provided with a receiving member on the lower front side, and a front door provided with a sag preventing member on the lower rear side, wherein the front door is In the gaming machine, which is pivotally supported in front of the gaming machine body via a hinge mechanism so as to be opened and closed, and the drooping prevention member is supported by the receiving member when the front door is closed, the dripping prevention The member is composed of a synthetic resin insertion body having a protrusion and a metal leaf spring having a contact piece, and the contact piece protrudes downward from an opening provided on the bottom surface of the protrusion, and the receiving member Is made of a sheet metal grounding plate connected to the ground, and when the front door is closed, the lower surface of the protruding portion is brought into contact with the grounding plate and the contact piece is elastically contacted with the grounding plate. I made it.
このように構成された遊技機では、前面扉が遊技機本体に対して閉じられているとき、前面扉の下部背面側に設けた差し込み体の突出部が遊技機本体の下部前面側に設けた受け部材(接地板)上に当接するため、前面扉が自重で下方に垂れることを確実に防止できる。そして、前面扉を遊技機本体に対して開閉動作するとき、合成樹脂で成形された突出部の下面が板金製の受け部材上を摺動するため、両者の摺動が滑らかになって前面扉をスムーズに開閉動作することが可能になる。さらに、前面扉の閉鎖時に突出部の底面から下方へ突出する板ばねの接触片が受け部材(接地板)上に弾接するため、前面扉に発生または帯電した静電気を板ばねと受け部材を介して遊技機本体側にアースすることができ、前面扉の垂れ防止構造を利用したコンパクトで簡素化されたアース構造を実現できる。 In the gaming machine configured as described above, when the front door is closed with respect to the gaming machine main body, the protruding portion of the insert provided on the lower back side of the front door is provided on the lower front side of the gaming machine main body. Since it abuts on the receiving member (ground plate), the front door can be reliably prevented from drooping downward due to its own weight. When the front door is opened and closed with respect to the gaming machine main body, the lower surface of the protruding portion formed of synthetic resin slides on the sheet metal receiving member, so that the sliding of both is smooth and the front door Can be opened and closed smoothly. Further, since the contact piece of the leaf spring that protrudes downward from the bottom surface of the protruding portion when the front door is closed is elastically contacted on the receiving member (ground plate), static electricity generated or charged on the front door is passed through the leaf spring and the receiving member. Thus, it is possible to ground to the gaming machine main body side, and it is possible to realize a compact and simplified ground structure using a front door droop prevention structure.
上記の構成において、接触片が板ばねに片持ち状に形成されていると共に、差し込み体に接触片の自由端側を包囲する収納凹部が設けられており、前面扉の開放時に、接触片の自由端側が収納凹部の内底面に弾接して位置規制されるようになっていると、前面扉を開放動作したときに、接触片の自由端側が作業者等に引っ掛かって不用意に変形してしまうことを防止できる。 In the above configuration, the contact piece is formed in a cantilever shape on the leaf spring, and the insertion recess is provided with a storage recess that surrounds the free end side of the contact piece. If the position of the free end is elastically contacted with the inner bottom surface of the storage recess and the position is restricted, when the front door is opened, the free end side of the contact piece is caught by an operator or the like, and it is inadvertently deformed. Can be prevented.
本発明の遊技機では、前面扉に設けた合成樹脂製の差し込み体と遊技機本体に設けた板金製の受け部材(接地板)とを用いて前面扉の垂れを防止するようになっており、前面扉を遊技機本体に対して開閉動作するとき、差し込み体の突出部と接地板との摺動が金属同士に比べて滑らかになるため、前面扉をスムーズに開閉動作することができる。また、前面扉の閉鎖時に突出部の底面から下方へ突出する板ばねの接触片を受け部材上に弾接させたので、前面扉に発生または帯電した静電気を板ばねと受け部材を介して遊技機本体側にアースすることができ、前面扉の垂れ防止構造を利用したコンパクトで簡素化されたアース構造を実現できる。 In the gaming machine of the present invention, the front door is prevented from sagging by using a synthetic resin insertion body provided on the front door and a sheet metal receiving member (grounding plate) provided on the gaming machine main body. When the front door is opened and closed with respect to the gaming machine main body, the sliding between the protrusion of the insert and the ground plate is smoother than that between metals, so the front door can be opened and closed smoothly. In addition, since the contact piece of the leaf spring that protrudes downward from the bottom surface of the protruding portion is elastically contacted on the receiving member when the front door is closed, the static electricity generated or charged on the front door is played through the leaf spring and the receiving member. It can be grounded to the machine body side, and a compact and simplified grounding structure can be realized using a structure for preventing the front door from drooping.

このような形状の板ばね21を差し込み体20に組み込む場合は、平板部21bを突出部20bの開放端から内部に挿入すると共に、位置決め孔21dをボス20cに一致させた状態で取付板部21aを保持板部20aに重ね合わせれば良い。これにより、平板部21bの先端部がリブ20eの下端に入り込んで位置決めされると共に、接触片21cが開口20dを挿通して突出部20bの下方へ突出した状態となり、図4に示すように、差し込み体20と板ばね21が一体化された垂れ防止部材8のユニット品を得ることができる。そして、かかるユニット品の状態で差し込み体20の保持板部20aと板ばね21の取付板部21aとを前面扉3の背面に複数本のねじ(図示省略)を用いて固定することにより、図2に示すように、垂れ防止部材8が前面扉3の背面から突出して本体枠2の前面に固定された受け部材7と対峙する。その際、前面扉3の背面側には開口3aを包囲するように導体板30が取り付けられており、垂れ防止部材8を前面扉3の背面に固定することによって、板ばね21の取付板部21aが導体板30の一部に接続するようになっている。 When the plate spring 21 having such a shape is incorporated in the insert body 20, the flat plate portion 21b is inserted into the inside from the open end of the projecting portion 20b, and the mounting plate portion 21a is aligned with the positioning hole 21d on the boss 20c. May be superimposed on the holding plate portion 20a. As a result, the tip of the flat plate portion 21b enters the lower end of the rib 20e and is positioned, and the contact piece 21c passes through the opening 20d and protrudes downward from the protruding portion 20b, as shown in FIG. A unit product of the sagging prevention member 8 in which the insertion body 20 and the leaf spring 21 are integrated can be obtained. Then, by fixing the holding plate portion 20a of the insert 20 and the mounting plate portion 21a of the leaf spring 21 to the back surface of the front door 3 using a plurality of screws (not shown) in such a unit product state. 2, the sag prevention member 8 protrudes from the back surface of the front door 3 and faces the receiving member 7 fixed to the front surface of the main body frame 2. At that time, the conductive plate 30 is attached to the back side of the front door 3 so as to surround the opening 3a, and the sag prevention member 8 is fixed to the back side of the front door 3 to thereby attach the plate portion of the leaf spring 21. 21 a is connected to a part of the conductor plate 30.
本実施形態例に係るパチンコ機Pにおいて、常態では、本体枠2が機枠1に対して閉じられていると共に、前面扉3が本体枠2に対して閉じられているため、何人も内部の遊技盤や電子機器類に触れることができないようになっている。この場合、図6(c)に示すように、前面扉3の下部背面側に固定した垂れ防止部材8のうち、合成樹脂で成形された差し込み体20の突出部20bが本体枠2の下部前面側に固定した受け部材7のガイド部7a上に当接しているため、前面扉3が自重で下方に垂れることを確実に防止できる。また、かかる前面扉3の閉鎖状態において、突出部20bの開口20dから下方へ突出する板ばね21の接触片21cが受け部材7のガイド部7a上に弾接しているため、前面扉3に発生または帯電した静電気を導体板30から板ばね21と受け部材(接地板)7を介して本体枠2側にアースすることができる。しかも、板ばね21の平板部21bに片持ち梁状に形成された接触片21cは、ガイド部7aに当接することで収納凹部20eの内底面から離れる方向へ撓ませられるため、その反力を受けて接触片21cは受け部材7のガイド部7a上に大きな接触圧で弾接した状態となる。したがって、遊技者が前面扉3を叩いたり揺すったりして大きな外力が作用したとしても、その外力によって板ばね21の接触片21cが受け部材7のガイド部7aから離反する虞は少なく、長期に亘って確実なアース経路を確保することができる。 In the pachinko machine P according to this embodiment, since the main body frame 2 is closed with respect to the machine frame 1 and the front door 3 is closed with respect to the main body frame 2 in the normal state, The game board and electronic devices cannot be touched. In this case, as shown in FIG. 6C, the protrusion 20 b of the insert 20 formed of synthetic resin is the lower front surface of the main body frame 2 among the sagging prevention members 8 fixed to the lower back side of the front door 3. Since it contacts on the guide part 7a of the receiving member 7 fixed to the side, it can prevent reliably that the front door 3 hangs down with dead weight. Further, in the closed state of the front door 3, the contact piece 21 c of the leaf spring 21 protruding downward from the opening 20 d of the protruding portion 20 b is elastically contacted on the guide portion 7 a of the receiving member 7. Alternatively, the charged static electricity can be grounded from the conductor plate 30 to the main body frame 2 side via the leaf spring 21 and the receiving member (ground plate) 7. In addition, the contact piece 21c formed in a cantilever shape on the flat plate portion 21b of the leaf spring 21 is deflected in a direction away from the inner bottom surface of the storage recess 20e by contacting the guide portion 7a. Upon receipt, the contact piece 21c is in elastic contact with the guide portion 7a of the receiving member 7 with a large contact pressure. Therefore, even if a player hits or shakes the front door 3 and a large external force is applied, the contact piece 21c of the leaf spring 21 is less likely to separate from the guide portion 7a of the receiving member 7 due to the external force. A reliable ground path can be ensured.
そして、遊技盤に発生した球詰まり等を解消するために、前面扉3を本体枠2に対して開放すると、図6(b)から図6(a)に示すように、その開放動作の初期段階で突出部20bの下面が受け部材7のガイド部7a上を手前側へ摺動した後、垂れ防止部材8は受け部材7から離反する。このとき、合成樹脂で成形された突出部20bの下面が金属板からなる受け部材7のガイド部7a上を摺動するため、両者の摺動が滑らかになって前面扉3をスムーズに開放動作することができる。また、板ばね21の接触片21cは受け部材7から離れることによって開口3aから突出する向き(下方)に弾性復帰しようとするが、その場合、接触片21cの自由端側が収納凹部20eの内底面に当接時点で、接触片21cはそれ以上移動しないように位置規制されるため、前面扉3の開放動作中に接触片21cの自由端側が作業者等に引っ掛かって不用意に変形することを防止できる。 Then, when the front door 3 is opened with respect to the main body frame 2 in order to eliminate ball clogging or the like occurring in the game board, as shown in FIGS. 6 (b) to 6 (a), the initial opening operation is performed. After the lower surface of the protruding portion 20 b slides forward on the guide portion 7 a of the receiving member 7 in the stage, the sag prevention member 8 is separated from the receiving member 7. At this time, since the lower surface of the protruding portion 20b formed of synthetic resin slides on the guide portion 7a of the receiving member 7 made of a metal plate, the sliding of both is smooth and the front door 3 is smoothly opened. can do. Further, the contact piece 21c of the leaf spring 21 tends to elastically return in the direction (downward) protruding from the opening 3a by separating from the receiving member 7, but in this case, the free end side of the contact piece 21c is the inner bottom surface of the storage recess 20e. Since the position of the contact piece 21c is restricted so as not to move any more at the time of contact, the free end side of the contact piece 21c is caught by an operator or the like during the opening operation of the front door 3 and is inadvertently deformed. Can be prevented.
なお、球詰まり等の解消後に前面扉3を再び本体枠2に対して閉鎖する場合、垂れ防止部材8は上記と逆の手順を経て受け部材7に係合する。すなわち、前面扉3の閉鎖動作に伴って垂れ防止部材8が受け部材7に近付くと、まず、図6(a)に示すように、突出部20bの先端側下面が受け部材7のガイド部7aの手前側に乗り上げる。次いで、前面扉3をさらに閉鎖方向へ回動すると、図6(b)から図6(c)に示すように、突出部20bの下面がガイド部7a上を奥側に向かって摺動すると共に、板ばね21の接触片21cがガイド部7aに当接して弾性変形する。この場合も、合成樹脂で成形された突出部20bの下面が金属板からなるガイド部7a上を摺動するため、両者の摺動が滑らかになって前面扉3をスムーズに閉鎖動作することができる。また、前面扉3の閉鎖状態において、板ばね21の接触片21cがガイド部7a上に弾接するため、前面扉3に発生または帯電した静電気を導体板30から板ばね21と受け部材(接地板)7を介して本体枠2側にアースすることができる。 When the front door 3 is closed again with respect to the main body frame 2 after the ball clogging or the like is eliminated, the drooping prevention member 8 is engaged with the receiving member 7 through the reverse procedure. That is, when the drooping prevention member 8 approaches the receiving member 7 in accordance with the closing operation of the front door 3, first, as shown in FIG. 6A, the lower surface on the front end side of the protruding portion 20b is the guide portion 7a of the receiving member 7. Get on the near side. Next, when the front door 3 is further rotated in the closing direction, as shown in FIGS. 6B to 6C, the lower surface of the protruding portion 20b slides on the guide portion 7a toward the back side. The contact piece 21c of the leaf spring 21 comes into contact with the guide portion 7a and is elastically deformed. Also in this case, since the lower surface of the projecting portion 20b formed of synthetic resin slides on the guide portion 7a made of a metal plate, the sliding of both of them becomes smooth and the front door 3 can be closed smoothly. it can. Further, in the closed state of the front door 3, the contact piece 21c of the leaf spring 21 is elastically contacted on the guide portion 7a, so that static electricity generated or charged on the front door 3 from the conductor plate 30 to the leaf spring 21 and the receiving member (ground plate). ) 7 can be grounded to the main body frame 2 side.
以上説明したように、本実施形態例に係るパチンコ機(遊技機)Pでは、前面扉3が本体枠(遊技機本体)2に対して閉じられているとき、前面扉3の下部背面側に固定した垂れ防止部材(差し込み体20と板ばね21)8のうち、合成樹脂で成形された差し込み体20の突出部20bが本体枠2の下部前面側に固定した受け部材7のガイド部7a上に当接するようになっているため、前面扉3が自重で下方に垂れることを確実に防止できる。そして、前面扉3を本体枠2に対して開閉動作するとき、合成樹脂で成形された突出部20bの下面が金属板からなる受け部材7のガイド部7a上を摺動するため、両者の摺動が金属同士に比べて滑らかになり、前面扉3をスムーズに開閉動作することができる。また、前面扉3の閉鎖状態において、突出部20bの開口20dから下方へ突出する板ばね21の接触片21cが受け部材7のガイド部7a上に弾接しているため、前面扉3に発生または帯電した静電気を導体板30から板ばね21と受け部材(接地板)7を介して本体枠2側にアースすることができ、前面扉3の垂れ防止構造を利用したコンパクトで簡素化されたアース構造を実現することができる。 As described above, in the pachinko machine (game machine) P according to this embodiment, when the front door 3 is closed with respect to the main body frame (game machine main body) 2, Among the fixed sag prevention members (insert 20 and leaf spring 21) 8, the protruding portion 20b of the insert 20 formed of synthetic resin is on the guide portion 7a of the receiving member 7 fixed to the lower front side of the main body frame 2. Therefore, the front door 3 can be reliably prevented from drooping downward due to its own weight. When the front door 3 is opened and closed with respect to the main body frame 2, the lower surface of the projecting portion 20b formed of synthetic resin slides on the guide portion 7a of the receiving member 7 made of a metal plate. The movement is smoother than that between metals, and the front door 3 can be opened and closed smoothly. Further, in the closed state of the front door 3, the contact piece 21 c of the leaf spring 21 protruding downward from the opening 20 d of the protruding portion 20 b is elastically contacted on the guide portion 7 a of the receiving member 7. The charged static electricity can be grounded from the conductor plate 30 via the leaf spring 21 and the receiving member (grounding plate) 7 to the main body frame 2 side, and a compact and simplified ground using the structure for preventing the front door 3 from drooping. A structure can be realized.
また、接触片21cが板ばね21の平板部21bに片持ち状に形成されていると共に、差し込み体20に接触片21cの自由端側を包囲する収納凹部20eが形成されており、前面扉3の閉鎖時に、接触片21cの自由端側が収納凹部20eの内底面に弾接して位置規制されるようになっているため、前面扉3の開放動作中に接触片21cの自由端側が作業者等に引っ掛かって不用意に変形することを防止できる。 Further, the contact piece 21c is formed in a cantilever manner on the flat plate portion 21b of the leaf spring 21, and the housing 20 is formed in the insert 20 so as to surround the free end side of the contact piece 21c. When the front door 3 is closed, the free end side of the contact piece 21c is elastically contacted with the inner bottom surface of the storage recess 20e so that the position of the contact piece 21c is regulated. Can be prevented from being inadvertently deformed.
