従来この種の遊技機のヒンジ構造としては、例えば、特開平８−１５０２５２号に示すようなものがある。
【０００３】
すなわち、図５に示したように、前枠の内部に設けた取付ピン１と、取付ピン１の一方の端部が前枠から上下方向に突出し得るように取付ピン１を付勢しつつ取付ピン１を上下方向に可動状態にて支持することが可能な取付ピン支持手段２と、前枠から突出した取付ピン１を前枠方向に退行させることが可能な取付ピン退行手段とを有し、取付ピン支持手段２又は取付ピン退行手段３には、取付ピン１が上下方向に突出した状態にて取付ピン１の前枠方向への退行を阻止することが可能なロック機構４を設けた前枠ヒンジ構造を有するもので、前枠への取付が容易で、前枠を簡易且つ確実に外枠に取り付けることを可能にしようとするものである。
【０００４】
【発明が解決しようとする課題】
しかしながら、このような従来の遊技機のヒンジ構造では、図５に示したよううに構造が複雑且つ部品点数が多いため、製造コストが上昇するという問題点があった。
【０００５】
また、構造が複雑且つ部品点数が多いことはそれだけ故障発生の可能性のある部分が増えるという問題点もあった。
【０００６】
本発明は、このような従来の問題点に着目してなされたもので、構造が簡単で部品数が少なく、且つ、前枠を簡易且つ確実に外枠に取り付けることが可能な遊技媒体のヒンジ構造を提供することを目的としている。
【０００７】
【課題を解決するための手段】
かかる目的を達成するための要旨とするところは、次の項に存する。
【０００８】
［１］遊技機（Ａ）の前枠（１０）に取り付け、当該前枠（１０）を遊技機（Ａ）の外枠（２０）に着脱可能に取付けるための遊技機の前枠ヒンジ構造において、
前記前枠（１０）の上端の角部および同一側の下端の角部に刻設したピン受部（１１）と、
当該ピン受部（１１）に取付ける前枠基体（１２Ａ、１２Ｂ）と、
前記ピン受部（１１）に収納され、前記外枠（２０）に取り付けられた外枠基体（２１Ａ、２１Ｂ）と係合可能なピン体であって、該外枠基体（２１Ａ、２１Ｂ）に係合する側が外枠と係合可能な先細りの形状を有する取付ピン（１３）と、
前記ピン受部（１１）に収納されて前記取付ピン（１３）をその全長方向に付勢する付勢部材（１４）とでもって形成され、
前記取付けピン（１３）は、前記ピン受部（１１）に収納されるベース部（１３ａ）と、前記外枠基体（２１Ａ、２１Ｂ）と係合する係合部（１３ｂ）と、を有し、
前記ベース部（１３ａ）は前記ピン受部（１１）内での前記取付ピン（１３）の回転を防止する形状を有し、
前記外枠基体（２１Ａ、２１Ｂ）に係合する側の前記係合部（１３ｂ）は、円柱体の途中から先端にかけて一つの平面で形成され、かつ斜に先細りの形状を形成する傾斜面（１３ｃ）を有し、
前記前枠（１０）を外枠（２０）に取り付けて閉めたときに、前記傾斜面（１３ｃ）が遊技盤面側に向き、前記係合部（１３ｂ）が前記外枠基体（２１Ａ、２１Ｂ）と当接するように前記ベース部（１３ａ）を前記ピン受部（１１）に収納したことを特徴とする遊技機の前枠ヒンジ構造。
【００１１】
次に作用を説明する。
【００１２】
遊技機（Ａ）の外枠（２０）の一方の側の上端の角部には外枠基体（２１Ａ）を取り付け、同一側の下端の角部には外枠基体（２１Ｂ）を取り付ける。
【００１３】
一方、前枠（１０）上端の角部および同一側の下端の角部には各々ピン受部（１１、１１）を刻設しておき、そのピン受部（１１、１１）内に付勢部材（１４）であるコイルスプリングを入れ、さらに取付ピン（１３）をいれる。このとき、取付ピン（１３）の係合部（１３ｂ）に形成した傾斜面（１３ｃ）は、前枠（１０）を外枠（２０）に取り付けて閉めたときに遊技盤面側を向く向きに挿入する。
【００１４】
その次に、前枠（１０）上端側のピン受部（１１）上に前枠基体（１２Ａ）を取り付け、下端側のピン受部（１１）に前枠基体（１２Ｂ）を取り付ける。
【００１５】
取付ピン（１３）のベース部（１３ａ）はピン受部（１１）内で回らない形状にされているので、前記傾斜面（１３ｃ）の向きは固定される。
【００１６】
取付ピン（１３）はベース部（１３ａ）の底部（１３０）から付勢部材（１４）によって付勢されているので、取付ピン（１３）の係合部（１３ｂ）は最も突出した状態にある。
【００１７】
前枠（１０）を外枠（２０）に取り付けるときは、それらが相対する状態で前枠（１０）の前枠基体（１２Ａ、１２Ｂ）と外枠（２０）の外枠基体（２１Ａ、２１Ｂ）の位置を合わせて、そのまま前枠（１０）を外枠（２０）に押し付ければよい。
【００１８】
押し付けることによって、取付ピン（１３）の係合部（１３ｂ）の傾斜面（１３ｃ）が外枠（２０）の外枠基体（２１Ａ、２１Ｂ）に押し付けられ、それによって取付ピン（１３）は付勢部材（１４）の付勢力に抗してピン受部（１１）内に沈み込み、外枠基体（２１Ａ、２１Ｂ）に穿設した開口のところで付勢部材（１４）の付勢力によって突出し、取り付けられる。
【００１９】
前枠（１０）を外枠（２０）に取り付けた状態では、前記係合部（１３ｂ）は外枠基体（２１Ａ、２１Ｂ）の開口の縁部に当接している。
【００２０】
外枠（２０）から前枠（１０）を取り外すときは、前枠（１０）が外枠（２０）と略直角になるところまで開き、そのまま係合部（１３ｂ）の傾斜面（１３ｃ）が面している方向に前枠（１０）をずらせば、傾斜面（１３ｃ）が開口の縁部に押し付けられ、それによって取付ピン（１３）は付勢部材（１４）の付勢力に抗してピン受部（１１）内に沈んで行くので係合部（１３ｂ）が外れるまで押し続ければよい。
【００２１】
このようにして、前枠（１０）を簡易且つ確実に外枠（２０）に取り付けることができる。
【００２２】
【発明の実施の形態】
以下、図面に基づき本発明の一実施の形態を説明する。
【００２３】
図１から図４は本発明の一の実施の形態を示している。
【００２４】
図１に示すように、前枠ヒンジ構造は、遊技機Ａの前枠１０を外枠２０に着脱可能に取付けるための前枠ヒンジの構造である。
【００２５】
前枠１０の上端の左角部には切欠き部１５Ａが設けられている。切欠き部１５Ａは前枠１０の上端面１６Ａと平行な平面部を有し、そこに角柱の輪郭を有するピン受部１１が前枠１０の下端面に向けて刻設されている。
【００２６】
このピン受部１１には付勢部材であるコイルスプリング１４が収められている。
【００２７】
コイルスプリング１４の上には後に説明する外枠２０に取り付けた外枠基体２１Ａと係合して前枠１０を取り付けるための取付ピン１３が収められている。
【００２８】
取付ピン１３は図２の（Ａ）、（Ｂ）および（Ｃ）に明示されている。（Ａ）は、取付ピン１３の平面図であり、（Ｂ）は左側面図、（Ｃ）は正面図である。
【００２９】
取付けピン１３は、前枠１０のピン受部１１に収納されるベース部１３ａと、外枠基体２１Ａと係合する係合部１３ｂと、が形成されている。各図から分かるように、ベース部１３ａは横断面が正方形であり、縦断面が長方形の四角柱状に形成されている。ベース部１３ａの外寸はピン受部１１内で取付ピン１３の回転が起こらない程度であればよいが、がたつきを生じさせないためには正方形の横断面の四辺はピン受部１１の寸法に略等しいことが好ましい。一方、ベース部１３ａの長さは、ピン受部１１の深さよりも短いが、ベース部１３ａの長さと自然の状態にあるコイルスプリング１４の長さを足した全長は、ピン受部１１の深さよりも充分長い大きさに取られている。
【００３０】
ベース部１３ａの上に形成された係合部１３ｂは、直径がベース部材１３ａの正方形の断面の一辺よりも小さい円柱体をベース部１３ａの上面の中心に円の中心が来るようにベース部１３ａの長手方向に延設したものであり、途中から先端に向かって斜めに切り落とした傾斜面１３ｃを有している。
【００３１】
取付ピン１３は、前枠１０を外枠２０に取り付けて閉めたときに、径斜面１３ｃが遊技盤面側に向く方向でピン受部１１内に収められている。
【００３２】
取付ピン１３とコイルスプリング１４とをピン受部１１に収めた状態で、切欠き部１５Ａに前枠基体１２Ａが螺子止めされている。前枠基体１２Ａには取付ピンの係合部１３ｂが出没可能なようにピン開口１２Ｈが形成されている。
【００３３】
前枠１０の下端の左角部にも形状は切欠き部１５Ａと異なるが同様の目的をもって切欠き部１５Ｂが設けられている。また、ピン受部１１、コイルスプリング１４および取付ピン１３は前枠１０の上端の左角部に設けたものと同一のものが設けられている。また、切欠き部１５Ｂは切欠き部１５Ａと形状が異なるため、取り付ける前枠基体１２Ｂの形状も異なるが、前枠基体１２Ａに形成したピン開口１２Ｈと同様のピン開口１２Ｈが形成されている。
【００３４】
図１および図３に示したように、遊技機Ａの外枠２０の上端の左角部には外枠基体２１Ａが、下端の左角部には外枠基体２１Ｂが螺子止めされている。外枠基体２１Ａ、２１Ｂは、取り付けたときに外枠基体より前方に突出した突出片の形状は異なるが、各々には前枠１０を取り付けたときに取付ピン１３が貫通するピン開口２１Ｈが形成されている。
【００３５】
次に作用を説明する。
【００３６】
遊技機Ａの外枠２０の一方の側の上端の角部にはピン開口２１Ｈの形成された突出片が手前に来るように外枠基体２１Ａを螺子で取り付ける。同様に同じ側の下端の角部には外枠基体２１Ｂを取り付ける。
【００３７】
一方、前枠１０上端の角部および同じ側の下端の角部には各々四角柱状にピン受部１１、１１を刻設しておき、そのピン受部１１、１１内に付勢部材１４であるコイルスプリングを入れる。さらに取付ピン１３をいれる。このとき、取付ピン１３の係合部１３ｂに形成した傾斜面１３ｃは、前枠１０を外枠２０に取り付けて閉めたときに遊技盤面側を向く向きに挿入する。
【００３８】
その次に、前枠１０上端側のピン受部１１上に前枠基体１２Ａを取り付け、下端側のピン受部１１に前枠基体１２Ｂを取り付けるが、このとき、ピン受部１１、１１から突出している取付ピン１３の係合部１３ｂをそれぞれピン開口１２Ｈに貫通させて取り付ける。
【００３９】
このようにして取り付けた取付ピン１３は、そのベース部１３ａがピン受部１１内では回転できないので係合部１３ｂの傾斜面１３ｃの向きは固定される。
【００４０】
一方、取付ピン１３はベース部１３ａの底部１３０からコイルスプリング１４によって付勢されているので、ベース部１３ａはピン受部１１内でその長手方向に縦動可能である。取付ピン１３の係合部１３ｂはコイルスプリング１４の付勢力によりベース部１３ａの上面部が前枠基体１２Ａ、１２Ｂに当接した状態にあるとき最も突出した状態にある。
【００４１】
前枠１０を外枠２０に取り付けるときは、図３に示したように、それらが相対する状態で前枠１０の前枠基体１２Ａ、１２Ｂの位置と外枠２０の外枠基体２１Ａ、２１Ｂの位置を合わせて、そのまま前枠１０を外枠２０に押し付ければよい。
【００４２】
押し付けることによって、取付ピン１３の係合部１３ｂの傾斜面１３ｃが外枠基体２１Ａ、２１Ｂの突出片に押し付けられる。突出片が係合部１３ｂの傾斜面１３ｃを押す力の取付ピン１３の長手方向の成分がコイルスプリング１４の付勢力に抗して取付ピン１３をピン受部１１内に沈み込ませる。さらに前枠１０を押し続け、取付ピン１３の係合部１３ｂの先端が外枠基体２１Ａ、２１Ｂに穿設したピン開口２１Ｈ内に入ると、取付ピン１３はピン受部１１内に沈み込ませる力を受けなくなるのでコイルスプリング１４の付勢力によって突出する。
【００４３】
このようにして前枠１０を外枠２０に取り付けた状態では、係合部１３ｂの傾斜面１３ｃは完全には外枠基体２１Ａ、２１Ｂのピン開口２１Ｈ、２１Ｈの上に突き出てはおらず、ピン開口２１Ｈ、２１Ｈの内縁部に当接している。しかし、前述のように、傾斜面１３ｃは、遊技機Ａに相対する方向に向いて不動であるので、そのままで前枠１０上下、前後、左右の何れの向きに動かそうとしても前枠１０が外枠２０から外れることはない。
【００４４】
前枠１０を外枠２０から取り外すときは、図４に示したように、先ず、前枠１０が外枠２０と略直角になるところまで開く。このとき、前枠１０に取り付けた取付ピン１３の係合部１３ｂの傾斜面１３ｃは、図示したように右側を向いている。その状態で、傾斜面１３ｃの向いた方向、すなわち図４において矢印で示した方向に前枠１０をずらせば、傾斜面１３ｃがピン開口２１Ｈ、２１Ｈの内縁部に押し付けられ、取付ピン１３は上述のようにコイルスプリング１４の付勢力に抗してピン受部１１内に沈み込む。さらに矢印の方向にずらして行けば係合部１３ｂを外枠２０から外すことができる。
【００４５】
このようにして、前枠１０を簡易且つ確実に外枠２０に取り付け、また、取り外すことができる。
【００４６】
本形態では、係合部１３ｂ先端側を斜に切り落とした傾斜面１３ｃを有する形状のものを図示して説明したが、それに限らず、先細りの様々な形状とすることができる。
【００４７】
【発明の効果】
本発明にかかる遊技機の前枠ヒンジ構造によれば、構造が簡単で部品数が少ないので、簡単な操作で前枠を外枠に確実に取り付けることができ、且つ、取り外すことができる。
【００４８】
また、構造が簡単で部品数が少ないので、製造コストが低く、故障の発生も少ない。

When the front frame (10) is attached to the outer frame (20) and closed, the inclined surface (13c) faces the game board surface, and the engaging portion (13b) is the outer frame base (21A, 21B). A front frame hinge structure for a gaming machine, wherein the base portion (13a) is housed in the pin receiving portion (11) so as to come into contact with the front frame hinge.
[0011]
Next, the operation will be described.
[0012]
The outer frame base (21A) is attached to the upper corner of one side of the outer frame (20) of the gaming machine (A), and the outer frame base (21B) is attached to the lower corner of the same side.
[0013]
On the other hand, pin receiving portions (11, 11) are engraved at the corners of the upper end of the front frame (10) and the lower end of the same side, respectively, and biased in the pin receiving portions (11, 11). A coil spring as a member (14) is inserted, and a mounting pin (13) is further inserted. At this time, the inclined surface (13c) formed on the engaging portion (13b) of the mounting pin (13) is directed toward the game board surface when the front frame (10) is attached to the outer frame (20) and closed. insert.
[0014]
Next, the front frame base (12A) is mounted on the pin receiving portion (11) on the upper end side of the front frame (10), and the front frame base (12B) is mounted on the pin receiving portion (11) on the lower end side.
[0015]
Since the base portion (13a) of the mounting pin (13) is formed so as not to rotate in the pin receiving portion (11), the direction of the inclined surface (13c) is fixed.
[0016]
Since the mounting pin (13) is urged by the urging member (14) from the bottom (130) of the base portion (13a), the engaging portion (13b) of the mounting pin (13) is in the most protruding state. .
[0017]
When the front frame (10) is attached to the outer frame (20), the front frame base (12A, 12B) of the front frame (10) and the outer frame base (21A, 21B) of the outer frame (20) in a state where they face each other. ) And the front frame (10) may be pressed against the outer frame (20).
[0018]
By pressing, the inclined surface (13c) of the engaging portion (13b) of the mounting pin (13) is pressed against the outer frame base (21A, 21B) of the outer frame (20), whereby the mounting pin (13) is attached. Sinking into the pin receiving portion (11) against the urging force of the urging member (14) and protruding by the urging force of the urging member (14) at the opening formed in the outer frame base (21A, 21B), It is attached.

When the front frame (10) is attached to the outer frame (20), the engaging portion (13b) is in contact with the edge of the opening of the outer frame base (21A, 21B).
[0020]
When removing the front frame (10) from the outer frame (20), the front frame (10) opens to a position substantially perpendicular to the outer frame (20), and the inclined surface (13c) of the engaging portion (13b) is left as it is. If the front frame (10) is shifted in the facing direction, the inclined surface (13c) is pressed against the edge of the opening, so that the mounting pin (13) resists the biasing force of the biasing member (14). Since it sinks into the pin receiving portion (11), it may be kept pressed until the engaging portion (13b) is released.
[0021]
In this way, the front frame (10) can be easily and reliably attached to the outer frame (20).
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0023]
1 to 4 show an embodiment of the present invention.
[0024]
As shown in FIG. 1, the front frame hinge structure is a structure of a front frame hinge for detachably attaching the front frame 10 of the gaming machine A to the outer frame 20.
[0025]
A notch 15 </ b> A is provided at the left corner of the upper end of the front frame 10. The notch portion 15 </ b> A has a flat portion parallel to the upper end surface 16 </ b> A of the front frame 10, and a pin receiving portion 11 having a prismatic contour is carved toward the lower end surface of the front frame 10.
[0026]
The pin receiving portion 11 houses a coil spring 14 that is an urging member.
[0027]
Mounted on the coil spring 14 is an attachment pin 13 for attaching the front frame 10 by engaging with an outer frame base 21A attached to the outer frame 20 described later.
[0028]
The mounting pin 13 is clearly shown in FIGS. 2 (A), (B) and (C). (A) is a top view of the attachment pin 13, (B) is a left view, (C) is a front view.
[0029]
The mounting pin 13 is formed with a base portion 13a housed in the pin receiving portion 11 of the front frame 10 and an engaging portion 13b that engages with the outer frame base 21A. As can be seen from each figure, the base portion 13a is formed in a square column shape having a square cross section and a rectangular longitudinal section. The outer dimensions of the base portion 13a may be such that the mounting pin 13 does not rotate within the pin receiving portion 11, but the four sides of the square cross section are the dimensions of the pin receiving portion 11 in order to prevent rattling. Is preferably approximately equal to On the other hand, the length of the base portion 13a is shorter than the depth of the pin receiving portion 11, but the total length obtained by adding the length of the base portion 13a and the length of the coil spring 14 in a natural state is the depth of the pin receiving portion 11. It is taken to be sufficiently long.
[0030]
The engaging portion 13b formed on the base portion 13a has a cylindrical body whose diameter is smaller than one side of the square cross section of the base member 13a. The base portion 13a has a circular center at the center of the upper surface of the base portion 13a. It has an inclined surface 13c that is obliquely cut from the middle toward the tip.

When the front frame 10 is attached to the outer frame 20 and closed, the mounting pin 13 is accommodated in the pin receiving portion 11 in such a direction that the radial slope 13c faces the game board surface side.
[0032]
In a state where the mounting pin 13 and the coil spring 14 are housed in the pin receiving portion 11, the front frame base 12A is screwed to the notch portion 15A. A pin opening 12H is formed in the front frame base 12A so that the engaging portion 13b of the mounting pin can be projected and retracted.
[0033]
The left corner of the lower end of the front frame 10 is also provided with a notch 15B for the same purpose, although the shape is different from that of the notch 15A. Further, the pin receiving portion 11, the coil spring 14, and the mounting pin 13 are the same as those provided at the left corner of the upper end of the front frame 10. Further, since the shape of the cutout portion 15B is different from that of the cutout portion 15A, the shape of the front frame base 12B to be attached is also different, but a pin opening 12H similar to the pin opening 12H formed in the front frame base 12A is formed.
[0034]
As shown in FIGS. 1 and 3, the outer frame base 21A is screwed to the left corner of the upper end of the outer frame 20 of the gaming machine A, and the outer frame base 21B is screwed to the left corner of the lower end. The outer frame bases 21A and 21B have different shapes of protruding pieces that protrude forward from the outer frame base when attached, but each has a pin opening 21H through which the attachment pin 13 penetrates when the front frame 10 is attached. Has been.
[0035]
Next, the operation will be described.
[0036]
The outer frame base 21A is attached with a screw so that the protruding piece formed with the pin opening 21H comes to the front at the corner of the upper end of one side of the outer frame 20 of the gaming machine A. Similarly, the outer frame base 21B is attached to the corner of the lower end on the same side.
[0037]
On the other hand, pin receiving portions 11 and 11 are engraved in a rectangular column shape at the upper corner portion of the front frame 10 and the lower corner portion on the same side, and the biasing member 14 is provided in the pin receiving portions 11 and 11. Insert a coil spring. Further, the mounting pin 13 is inserted. At this time, the inclined surface 13c formed on the engaging portion 13b of the mounting pin 13 is inserted in a direction facing the game board surface when the front frame 10 is attached to the outer frame 20 and closed.
[0038]
Next, the front frame base 12A is mounted on the pin receiving portion 11 on the upper end side of the front frame 10, and the front frame base 12B is mounted on the pin receiving portion 11 on the lower end side. At this time, the front frame base 12B protrudes from the pin receiving portions 11 and 11. The engaging portions 13b of the mounting pins 13 are attached through the pin openings 12H.
[0039]
The mounting pin 13 attached in this way has its base portion 13a that cannot rotate within the pin receiving portion 11, so that the orientation of the inclined surface 13c of the engaging portion 13b is fixed.
[0040]
On the other hand, the mounting pin 13 is urged by the coil spring 14 from the bottom 130 of the base portion 13 a, so that the base portion 13 a can move vertically in the pin receiving portion 11. The engaging portion 13b of the mounting pin 13 is in the most protruding state when the upper surface portion of the base portion 13a is in contact with the front frame bases 12A and 12B by the biasing force of the coil spring 14.
[0041]
When the front frame 10 is attached to the outer frame 20, as shown in FIG. 3, the positions of the front frame bases 12A and 12B of the front frame 10 and the outer frame bases 21A and 21B of the outer frame 20 in a state where they face each other. The position may be adjusted and the front frame 10 may be pressed against the outer frame 20 as it is.
[0042]
By pressing, the inclined surface 13c of the engaging portion 13b of the mounting pin 13 is pressed against the protruding pieces of the outer frame bases 21A and 21B. The component in the longitudinal direction of the mounting pin 13 of the force by which the protruding piece pushes the inclined surface 13 c of the engaging portion 13 b resists the urging force of the coil spring 14 and sinks the mounting pin 13 into the pin receiving portion 11. When the front frame 10 is further pressed and the tip of the engaging portion 13b of the mounting pin 13 enters the pin opening 21H drilled in the outer frame bases 21A and 21B, the mounting pin 13 sinks into the pin receiving portion 11. Since it receives no force, it protrudes by the urging force of the coil spring 14.
[0043]
When the front frame 10 is attached to the outer frame 20 in this way, the inclined surface 13c of the engaging portion 13b does not completely protrude over the pin openings 21H and 21H of the outer frame bases 21A and 21B. It contacts the inner edge of the openings 21H and 21H. However, as described above, the inclined surface 13c does not move in the direction opposite to the gaming machine A. Therefore, the front frame 10 is not moved in any direction of the front frame 10 up and down, front and rear, and left and right. It does not come off from the outer frame 20.
[0044]
When removing the front frame 10 from the outer frame 20, first, as shown in FIG. 4, the front frame 10 is opened until it is substantially perpendicular to the outer frame 20. At this time, the inclined surface 13c of the engaging portion 13b of the mounting pin 13 attached to the front frame 10 faces the right side as illustrated. In this state, if the front frame 10 is shifted in the direction in which the inclined surface 13c faces, that is, the direction indicated by the arrow in FIG. 4, the inclined surface 13c is pressed against the inner edges of the pin openings 21H and 21H, and the mounting pin 13 is As described above, the pin receiving portion 11 sinks against the urging force of the coil spring 14. Further, the engaging portion 13b can be detached from the outer frame 20 by shifting in the direction of the arrow.
[0045]
In this way, the front frame 10 can be easily and reliably attached to and removed from the outer frame 20.
[0046]
In the present embodiment, the shape having the inclined surface 13c in which the distal end side of the engaging portion 13b is cut off obliquely has been illustrated and described, but the present invention is not limited thereto, and various shapes with a taper can be used.
[0047]
【The invention's effect】
According to the front frame hinge structure of the gaming machine according to the present invention, since the structure is simple and the number of parts is small, the front frame can be securely attached to and removed from the outer frame by a simple operation.
[0048]
In addition, since the structure is simple and the number of parts is small, the manufacturing cost is low and the occurrence of failures is small.
