Description

本発明は、遊技機に関し、特に遊技盤の前面を覆う透明板ユニットを備えた遊技機に関するものである。 The present invention relates to a gaming machine, and more particularly to a gaming machine including a transparent plate unit that covers a front surface of a gaming board.

従来、遊技機の一種であるぱちんこ機には、遊技盤を備えた内枠の前面部に前面枠が開閉自在に配置され、前面枠には遊技盤の前面を覆うガラス板が保持枠を介して設けられている。そして、前面枠を閉じた状態では、遊技盤の前面とガラス板との間には所定の距離を有する空間が形成され、発射手段により遊技盤の遊技領域に発射された遊技球は、遊技盤とガラス板との間の空間内を釘等に衝突しながら落下する。しかし、遊技盤の前面とガラス板との間の空間は、ガラス保持枠の前面枠への取付け精度や、遊技盤の前面枠への取り付け精度等に依存しており、前面枠の開閉の繰返しによりガラス保持枠の取付けガタが大きくなると、遊技盤の前面とガラス板との間の距離が変化し、これによって例えば遊技球の落下や遊技部品の動作に悪影響を及ぼしたり釘や遊技部品の箇所で球詰まりが発生しやすくなったりするなどの不具合を生じることがあった。 Conventionally, a pachinko machine, which is a type of gaming machine, has a front frame that can be opened and closed on the front of an inner frame provided with a gaming board, and a glass plate that covers the front of the gaming board is placed on the front frame via a holding frame. Is provided. When the front frame is closed, a space having a predetermined distance is formed between the front surface of the game board and the glass plate, and the game ball launched into the game area of the game board by the launching means It falls while colliding with a nail etc. in the space between the glass and the glass plate. However, the space between the front of the game board and the glass plate depends on the accuracy of attaching the glass holding frame to the front frame and the accuracy of attaching the game board to the front frame. If the backlash of the glass holding frame increases due to this, the distance between the front surface of the game board and the glass plate changes, and this may adversely affect the fall of the game ball or the operation of the game part, for example, the location of the nail or game part In some cases, the ball clogging is likely to occur.

そこで、遊技盤の前面とガラス板との間の距離を一定とするために、開閉扉（前面枠）に対してガラス扉枠を弾性部材を介して設けるようにした遊技機が提案されている（特許文献１参照）。 Therefore, in order to make the distance between the front surface of the game board and the glass plate constant, a gaming machine in which a glass door frame is provided via an elastic member with respect to the open / close door (front frame) has been proposed. (See Patent Document 1).

また、ガラス保持枠を第一の透明板を保持する第一の保持枠と、第二の透明板を保持する第二の保持枠とに二分割して、透明板をそれぞれ離間する方向へと付勢する付勢手段を備え、遊技盤の前面とガラス板との間の距離を一定とするようにした遊技機が提案されている（特許文献２参照）。 Further, the glass holding frame is divided into two parts, a first holding frame for holding the first transparent plate and a second holding frame for holding the second transparent plate, and the transparent plates are separated from each other. There has been proposed a gaming machine that includes an urging means for urging so that the distance between the front surface of the game board and the glass plate is constant (see Patent Document 2).

しかしながら、特許文献１に記載の遊技機にあっては、遊技盤の前面とガラス板との間の距離を一定とすることができるものの、前面枠に対してガラス保持枠を弾性部材を介して設けるようにしているため、前面枠とガラス保持枠との間に隙間が生じ、不正遊技者によって針金などをこの隙間に挿入して不正行為（ゴト行為）などが行われることがある。 However, in the gaming machine described in Patent Document 1, although the distance between the front surface of the gaming board and the glass plate can be made constant, the glass holding frame is attached to the front frame via an elastic member. Since it is provided, a gap is generated between the front frame and the glass holding frame, and a fraudulent act (got act) may be performed by inserting a wire or the like into the gap by an unauthorized player.

また、特許文献２に記載の遊技機にあっては、透明板の当接位置によってガラス保持枠が傾きやすく、遊技盤の前面とガラス板との間の距離が一定とならず、球詰まりが発生する虞がある。さらに、第一の保持枠に第二の保持枠が嵌っている構造であるため、第一の保持枠と第二の保持枠との隙間からガラス板とガラス板との間の空間に埃や塵が入り易い構造となっている。このため、埃や塵により遊技盤の視認性を損ね遊技機の見栄えが悪くなるという問題がある。さらに、ガラス板を保持枠の内面に接着するようにしているため、ガラス板の後面と保持体の後端面とが同一面とはならず、ガラス保持枠全体の厚みがどうしても厚くなり、ガラス保持枠をコンパクト化することができない問題がある。また、ガラス板が押されるとガラス板が外れる方向に負荷がかかるので、ガラス板の接着状態によってはガラス板が外れてしまうという問題がある。 In addition, in the gaming machine described in Patent Document 2, the glass holding frame is easily tilted depending on the contact position of the transparent plate, the distance between the front surface of the gaming board and the glass plate is not constant, and the ball is clogged. May occur. Further, since the second holding frame is fitted to the first holding frame, dust or dirt is introduced into the space between the glass plates from the gap between the first holding frame and the second holding frame. The structure is easy for dust to enter. For this reason, there is a problem that the visibility of the game board is impaired due to dust and dust, and the appearance of the game machine is deteriorated. Furthermore, since the glass plate is bonded to the inner surface of the holding frame, the rear surface of the glass plate and the rear end surface of the holding body are not the same surface, and the thickness of the entire glass holding frame is inevitably increased. There is a problem that the frame cannot be made compact. Moreover, since a load is applied in a direction in which the glass plate is detached when the glass plate is pressed, there is a problem that the glass plate is detached depending on the bonding state of the glass plate.

本発明は、上記課題に鑑みてなされたものであり、付勢手段を介して前後に分割したガラス保持枠のガラス板とガラス板との間の空間に埃や塵の侵入を防止すると共に、遊技盤面とガラス板との間の距離を一定に保つようにした遊技機を提供することにある。 The present invention has been made in view of the above problems, and prevents intrusion of dust and dust into the space between the glass plate and the glass plate of the glass holding frame divided forward and backward through the biasing means, An object of the present invention is to provide a gaming machine in which the distance between the game board surface and the glass plate is kept constant.

A rib 35a that gradually decreases downward is provided at the periphery of the locking piece 35, and serves to reinforce the locking piece 35 and to be easily inserted into the engaging portion 22 from above.

また、前後保持枠体１６Ａ，１６Ｂの支持片部３０の対向面に、後保持枠体１６Ｂを所定の範囲内で前後方向への移動を規制する軸部３６と筒部３７が設けられている。実施例では図３（ｂ）に示すように前保持枠体１６Ａに軸部３６が形成され、後保持枠体１６Ｂに筒部３７が形成され、軸部３６が筒部３７より長く形成されている。そして、その周囲に環状溝３８が形成され、この環状溝３８に圧縮ばね１７が収納される。 Further, a shaft portion 36 and a cylindrical portion 37 are provided on the opposing surfaces of the support piece portions 30 of the front and rear holding frame bodies 16A and 16B to restrict the rear holding frame body 16B from moving in the front and rear direction within a predetermined range. . In the embodiment, as shown in FIG. 3B, a shaft portion 36 is formed on the front holding frame body 16A, a cylinder portion 37 is formed on the rear holding frame body 16B, and the shaft portion 36 is formed longer than the cylinder portion 37. Yes. An annular groove 38 is formed around the circumference, and the compression spring 17 is accommodated in the annular groove 38.

前後保持枠体１６Ａ，１６Ｂへの前後ガラス板１２Ａ，１２Ｂの取付けは、前保持枠体１６Ａの前方（後保持枠体１６Ｂの後方）から取付段部３１に接着剤を塗布して前後ガラス板１２Ａ，１２Ｂを取付段部３１に当接させて接着固定する。このように前後保持枠体１６Ａ，１６Ｂに対して外方から前後ガラス板１２Ａ，１２Ｂを取付けるようにすることで、前後ガラス板１２Ａ，１２Ｂに隙間空間Ｓに向けて負荷（外力）が掛ったとしても、前後ガラス板１２Ａ，１２Ｂが取付段部３１に支持されているため前保持枠体１６Ａ（後保持枠体１６Ｂ）が押され前ガラス板１２Ａ（後ガラス板１２Ｂ）とともに動くことになる。したがって、前後ガラス板１２Ａ，１２Ｂに外力が加わったとしても、前後ガラス板１２Ａ，１２Ｂが前保持枠体１６Ａ（後保持枠体１６Ｂ）から外れるようなことはない。 The front and rear glass plates 12A and 12B are attached to the front and rear holding frame bodies 16A and 16B by applying an adhesive to the mounting step 31 from the front of the front holding frame body 16A (the rear side of the rear holding frame body 16B). 12A and 12B are brought into contact with the mounting step portion 31 to be bonded and fixed. By attaching the front and rear glass plates 12A and 12B to the front and rear holding frames 16A and 16B from the outside in this way, a load (external force) is applied to the front and rear glass plates 12A and 12B toward the gap space S. Even so, since the front and rear glass plates 12A and 12B are supported by the mounting step 31, the front holding frame body 16A (rear holding frame body 16B) is pushed and moves together with the front glass plate 12A (rear glass plate 12B). . Therefore, even if an external force is applied to the front and rear glass plates 12A and 12B, the front and rear glass plates 12A and 12B are not detached from the front holding frame body 16A (rear holding frame body 16B).

透明板ユニット１１の組付けは、前保持枠体１６Ａの四ヶ所の環状溝３８に圧縮ばね１７を収納（載置）し、後保持枠体１６Ｂを筒部３７が前保持枠体１６Ａの軸部３６に挿入されるように位置合わせする。そして、後保持枠体１６Ｂの後面側から軸部３６より大径の座付きビス３９を軸部３６に螺締めすることで、前後ガラス板１２Ａ，１２Ｂ間に隙間空間Ｓが形成され、後保持枠体１６Ｂが進退自在な状態で透明板ユニット１１が組付けられる。このとき、後保持枠体１６Ｂが進退自在に移動し得る範囲は凸条３３の高さより小さく設定されており、凸条３３は常に凹溝３２に入り込んだ状態にある。このように凸条３３が凹溝３２と嵌り込むことで、隙間空間Ｓに外部から塵や埃が入らないようにすることができる。 The transparent plate unit 11 is assembled by storing (loading) the compression springs 17 in the four annular grooves 38 of the front holding frame 16A, and the cylindrical portion 37 serving as the shaft of the front holding frame 16A. Align so that it is inserted into the part 36. Then, a screw 39 with a seat larger in diameter than the shaft portion 36 is screwed to the shaft portion 36 from the rear surface side of the rear holding frame body 16B, whereby a gap space S is formed between the front and rear glass plates 12A and 12B. The transparent plate unit 11 is assembled in a state where the body 16B can freely advance and retract. At this time, the range in which the rear holding frame 16B can move freely is set to be smaller than the height of the ridge 33, and the ridge 33 is always in the recessed groove 32. In this way, the protrusions 33 are fitted into the grooves 32, so that dust or dirt can be prevented from entering the gap space S from the outside.

次に、透明板ユニット１１を前面枠８に取付けるには、係止具２３をほぼ水平とした状態で、透明板ユニット１１の係止片３５を前面枠８の背面に設けた係合部２２の上方に位置させ、透明板ユニット１１を前面枠８の背面から窓口部１５に合わせる（図６（ａ）参照）。そして、この位置から透明板ユニット１１を前面枠８の背面に沿って下方に移動させ、係止片３５を係合部２２の袋状溝に支持させ、透明板ユニット１１が前面枠８の背面に保持される（図６（ｂ）参照）。次に、係止具２３を時計回りに９０度回動して操作部の先端が透明板ユニット１１の上面と近接して対向位置させる（図６（ｃ）及び図７参照）。これにより、透明板ユニット１１の上動が阻止され、係止片３５が係合部２２から外れることはなく、透明板ユニット１１は前面枠８に確実に保持される。このように、一つの係止具２３を操作するだけで透明板ユニット１１を固定保持できるので、組み付けの作業性が向上する。このとき、透明板ユニット１１は、前保持枠体１６Ａの係止片３５が前面枠８に固定されて取付けられているので、後保持枠体１６Ｂは図５に示すように圧縮ばね１７により後方に付勢され座付きビス３９に規制されており、圧縮ばね１７の付勢により前後ガラス板１２Ａ，１２Ｂ間が拡開した最後位置にある。そして、後保持枠体１６Ｂが前面枠８に対して進退自在な状態となっている。このときも、凸条３３の先端部は凹溝３２に入り込んだ状態にあり、前後ガラス板１２Ａ，１２Ｂ間の隙間空間Ｓに埃・塵が入り込むことはない。また、前面枠８と前保持枠体１６Ａとが密着しているため、前面枠８と前保持枠体１６Ａとの間から針金等の異物を挿入する悪戯を防止することができる。 Next, in order to attach the transparent plate unit 11 to the front frame 8, the engaging portion 22 provided with the locking piece 35 of the transparent plate unit 11 on the back surface of the front frame 8 with the locking member 23 being substantially horizontal. The transparent plate unit 11 is aligned with the window 15 from the back of the front frame 8 (see FIG. 6A). Then, the transparent plate unit 11 is moved downward along the back surface of the front frame 8 from this position, the locking piece 35 is supported by the bag-like groove of the engaging portion 22, and the transparent plate unit 11 is connected to the back surface of the front frame 8. (See FIG. 6B). Next, the locking tool 23 is rotated 90 degrees clockwise so that the front end of the operation unit is close to and opposed to the upper surface of the transparent plate unit 11 (see FIGS. 6C and 7). Thereby, the upward movement of the transparent plate unit 11 is prevented, and the locking piece 35 is not detached from the engaging portion 22, and the transparent plate unit 11 is securely held by the front frame 8. Thus, since the transparent plate unit 11 can be fixed and held only by operating one locking tool 23, the assembling workability is improved. At this time, since the transparent plate unit 11 is attached with the locking piece 35 of the front holding frame 16A fixed to the front frame 8, the rear holding frame 16B is moved backward by the compression spring 17 as shown in FIG. And is regulated by a seated screw 39, and is located at the last position where the space between the front and rear glass plates 12A and 12B is expanded by the bias of the compression spring 17. The rear holding frame body 16B is in a state of being able to advance and retract with respect to the front frame 8. Also at this time, the tip of the ridge 33 is in the state of entering the groove 32, and dust / dust does not enter the gap space S between the front and rear glass plates 12A and 12B. Further, since the front frame 8 and the front holding frame body 16A are in close contact with each other, it is possible to prevent a mischief that a foreign object such as a wire is inserted between the front frame 8 and the front holding frame body 16A.

また、透明板ユニット１１を外す際には、係止具２３を反時計回りに９０度回動して係止状態を解除し、この状態から透明板ユニット１１を上動させて係止片３５と係合部２２との係合を解除することで透明板ユニット１１を簡単に取り外すことができる。なお、実施例では係止具２３を操作した際に操作部２７の先端部が透明板ユニット１０の上面と近接して対向位置させるようにしたが、操作時に先端部を透明板ユニット１１の上面と接触させて透明板ユニット１１を係合保持するようにしてもよい。また、係止具２３を透明板ユニット１１の下方に設け、透明板ユニット１１の下方に設けた係止部に係止（掛止）して透明板ユニット１１の外れ移動を阻止するようにしてもよい。つまり、係止具２３によって透明板ユニット１１の外れる方向（係合方向と逆方向）への移動を阻止するようにすればよい。 Further, when the transparent plate unit 11 is removed, the locking tool 23 is turned 90 degrees counterclockwise to release the locked state, and the transparent plate unit 11 is moved upward from this state to lock the locking piece 35. The transparent plate unit 11 can be easily removed by releasing the engagement with the engaging portion 22. In the embodiment, when the locking tool 23 is operated, the distal end portion of the operation portion 27 is positioned close to and opposed to the upper surface of the transparent plate unit 10. The transparent plate unit 11 may be engaged with and held in contact with. Further, a locking tool 23 is provided below the transparent plate unit 11 and locked (latched) to a locking portion provided below the transparent plate unit 11 to prevent the transparent plate unit 11 from moving off. Also good. In other words, the movement in the direction in which the transparent plate unit 11 comes off (the direction opposite to the engagement direction) may be prevented by the locking tool 23.

このように、透明板ユニット１１を前面枠８に取付けた状態で、前面枠８を内枠３に対して閉じようとすると、後保持枠体１６Ｂの支持片部３０が装飾体１３の当接部１４に当接し、後保持枠体１６Ｂが規制された状態となり、図４に示すように後保持枠体１６Ｂを圧縮ばね１７の付勢に抗して前方に押され、後保持枠体１６Ｂと前保持枠体１６Ａとの間隔が狭まって前面枠８が閉じられる。このとき、透明板ユニット１１は後保持枠体１６Ｂの筒部３７が前保持枠体１６Ａの軸部３６と貫挿されていることにより、後保持枠体１６Ｂは軸部３６に案内され常に後ガラス板１２Ｂが平行状態を保持するように移動する。そして、凸条３３が凹溝３２にガイドされながら嵌合して、前後ガラス板１２Ａ，１２Ｂ間内に塵や埃が入らない状態で、遊技盤５面と後ガラス板１２Ｂとの間隔Ｄは一定となる。したがって、前面枠８にガタつきがあっても遊技盤５面と後ガラス板１２Ｂとの間隔Ｄは常に一定となり、遊技領域５ａ内で球噛み・球詰まりを発生させることはない。つまり、遊技者が前面枠８を手前に引っ張って遊技盤５面と後ガラス板１２Ｂとの間隔をわざと広げて遊技球を団子状に詰まらせて入賞口に入賞させる不正行為を防止することができる。また、隙間空間Ｓに塵や埃が入らないため遊技盤５の視認性を損なうこともない。 Thus, when the transparent plate unit 11 is attached to the front frame 8 and the front frame 8 is closed with respect to the inner frame 3, the support piece 30 of the rear holding frame body 16 B contacts the decorative body 13. The rear holding frame body 16B comes into contact with the portion 14 and is regulated, and the rear holding frame body 16B is pushed forward against the urging force of the compression spring 17 as shown in FIG. And the front holding frame 16A are narrowed, and the front frame 8 is closed. At this time, since the cylindrical portion 37 of the rear holding frame body 16B is inserted through the shaft portion 36 of the front holding frame body 16A, the rear holding frame body 16B is guided by the shaft portion 36 and is always rearward. The glass plate 12B moves so as to maintain the parallel state. The distance D between the game board 5 surface and the rear glass plate 12B is such that the protrusion 33 is fitted while being guided by the groove 32 and no dust or dirt enters between the front and rear glass plates 12A and 12B. It becomes constant. Therefore, even if the front frame 8 has a backlash, the distance D between the game board 5 surface and the rear glass plate 12B is always constant, and no ball biting or ball clogging occurs in the game area 5a. In other words, the player can pull the front frame 8 forward to intentionally widen the gap between the game board 5 surface and the rear glass plate 12B to prevent an illegal act of clogging the game balls into a ball shape and winning a prize opening. it can. Further, since dust or dust does not enter the gap space S, the visibility of the game board 5 is not impaired.

なお、保持枠体１６Ｂの後面と後ガラス板１２Ｂの後面とは略同一面となっているため、装飾体１３に後ガラス板１２Ｂを直接当接させるようにしても遊技盤５面と後ガラス板１２Ｂとの間隔Ｄは常に一定となる。このことから、例えば遊技領域５ａに設けられる表示装置１８の飾り枠１８ａを遊技盤５面から間隔Ｄと同じ高さ突出させ、表示装置１８を規制手段として表示装置１８の飾り枠１８ａに後ガラス板１２Ｂを当接させ、遊技盤５面と後ガラス板１２Ｂとの間隔Ｄを一定に保持させるようにしてもよい。 Since the rear surface of the holding frame 16B and the rear surface of the rear glass plate 12B are substantially the same surface, even if the rear glass plate 12B is brought into direct contact with the decorative body 13, the surface of the game board 5 and the rear glass The distance D from the plate 12B is always constant. For this reason, for example, the decorative frame 18a of the display device 18 provided in the game area 5a is projected from the game board 5 to the same height as the distance D, and the display device 18 is used as a restricting means to the decorative frame 18a of the display device 18 with the rear glass. You may make it contact | abut the board 12B and hold | maintain the space | interval D of the game board 5 surface and the rear glass board 12B uniformly.

また、実施例では付勢手段をコイル状の圧縮ばね１７としたが、板ばねを使用してもよい。さらに、付勢手段として圧縮ばね１７の代わりに、弾力性を有するウレタン等のエラストマーを使用してもよく、凹溝３２に配設してもよい。具体的には、図８に示すように凹溝３２内にエラストマーＥを装填（配設）し、前面枠８を開放した状態で、凸条３３が凹溝３２に嵌り込みエラストマーＥに接触した状態にある（図８（ａ）参照）。そして、前面枠８を閉じた状態で凹溝３２及び凸条３３が互いに嵌合し、その際に凸条３３がエラストマーＥを押圧し、エラストマーＥが弾性により圧縮変形する（図８（ｂ）参照）。このように、凹溝３２内にエラストマーＥを装填することで、複数個使用する圧縮ばね１７が不要となり部品点数を減らすことができ、透明板ユニット１１の組み立ての作業性が向上する。また、エラストマーＥが環状に設けられることで前後保持枠１６Ａ，１６Ｂの密着性が増して、前後ガラス板１２Ａ，１２Ｂ間の隙間空間Ｓに埃・塵が入り込むことを確実に防止することができる。当然のことながら、支持片部３０間と凹溝３２の両方にエラストマーＥを併設するようにしてもよい。 In the embodiment, the biasing means is the coiled compression spring 17, but a leaf spring may be used. Further, an elastic elastomer such as urethane may be used instead of the compression spring 17 as the urging means, and the urging means may be disposed in the concave groove 32. Specifically, as shown in FIG. 8, the elastomer E is loaded (arranged) in the concave groove 32, and the ridge 33 is fitted into the concave groove 32 in contact with the elastomer E in a state where the front frame 8 is opened. It is in a state (see FIG. 8A). Then, the groove 32 and the ridge 33 are fitted to each other with the front frame 8 closed, and at that time, the ridge 33 presses the elastomer E, and the elastomer E is compressed and deformed by elasticity (FIG. 8B). reference). In this way, by loading the elastomer E into the concave groove 32, a plurality of compression springs 17 are not required, the number of parts can be reduced, and the workability of assembling the transparent plate unit 11 is improved. Further, since the elastomer E is provided in an annular shape, the adhesion between the front and rear holding frames 16A and 16B is increased, and dust and dust can be reliably prevented from entering the space S between the front and rear glass plates 12A and 12B. . As a matter of course, the elastomer E may be provided in both the support piece portions 30 and the concave groove 32.
