Description

本発明は、パチンコ機の装飾装置に関し、より詳しくはパチンコ機の遊技盤前面を装飾する装飾装置に関する。   The present invention relates to a decoration device for a pachinko machine, and more particularly to a decoration device for decorating the front of a game board of a pachinko machine.

従来、この種の装飾装置として、浅い溝状の表示部を形成した透過性のシート材（以下、導光板という）を遊技盤の前面に配置し、さらにその導光板の端面に光源を配置して、光源からの光で導光板の表示部を照明する装飾装置が知られており、パチンコ機などの遊技機（以下単に遊技機という）に組み込まれ、遊技盤面を装飾することにより遊技性を高めるようにしている（特許文献１参照）。
また、遊技盤に透光性を有する装飾部材を設け、その装飾部材の遊技盤側に鋸歯状に反射面を形成することにより、遊技盤上に設けられたＬＥＤ光源からの光をその反射面で反射して、遊技盤を装飾する遊技機も知られている（特許文献２参照）。 Conventionally, as a decorative device of this type, a transparent sheet material (hereinafter referred to as a light guide plate) having a shallow groove-shaped display portion is disposed on the front surface of the game board, and a light source is disposed on the end surface of the light guide plate. In addition, a decoration device that illuminates the display portion of the light guide plate with light from a light source is known, and is incorporated in a gaming machine such as a pachinko machine (hereinafter simply referred to as a gaming machine), and the game board surface is decorated to decorate the game. It is made to raise (refer patent document 1).
Also, a decorative member having translucency is provided on the game board, and a reflective surface is formed in a sawtooth shape on the game board side of the decorative member, so that light from the LED light source provided on the game board is reflected on the reflective surface. There is also known a gaming machine that reflects the light and decorates the game board (see Patent Document 2).

近年、遊技機は遊技盤面中央のセンター役物に液晶表示装置などが組み込まれ、著名なキャラクタ又は人物の像などを遊技者に対して表示して、強いインパクトを与えるようにしている。一方では前記役物の周囲すなわち盤面の中央領域においても、装飾性を高めることにより、役物の演出との相乗効果を出して、一層の演出効果を行なうことが期待されている。   In recent years, a gaming machine has a liquid crystal display device or the like incorporated in a center role at the center of the game board surface, and displays a prominent character or image of a person to a player to give a strong impact. On the other hand, it is expected that a synergistic effect with the effect of the accessory will be produced by enhancing the decorativeness in the periphery of the accessory, that is, in the central region of the board surface.

しかしながら、上記の特許文献１に開示された装飾装置では、遊技盤の外側に光源を配置するために、光源から遠い中央領域の輝度が低下してしまう課題があった。
一方、光源を中央に配置すれば中央部分の輝度を高めることができるが、上述したように盤面中央には大型の役物が配置される傾向にあるため、光源を薄い導光板に照射させようとすると、光源を配置するためだけの新たに無駄な空間を生じることになり、活用できる遊技盤面領域が狭くなってしまうという課題があった。
また、導光板自体は薄い部材であるために、光源からの出射光の限られた一部しか導光板内に入射せず、利用効率が低いために、導光板の表示部を高輝度で光らせるためには、消費電力が大きく、高輝度の光源を用いなければならないという課題があった。 However, in the decoration device disclosed in Patent Document 1 described above, since the light source is arranged outside the game board, there is a problem that the luminance of the central region far from the light source is lowered.
On the other hand, if the light source is arranged at the center, the brightness of the central part can be increased, but as described above, a large accessory tends to be arranged at the center of the board surface. Then, a new useless space only for arranging the light source is generated, and there is a problem that a game board surface area that can be utilized becomes narrow.
In addition, since the light guide plate itself is a thin member, only a limited part of the light emitted from the light source is incident on the light guide plate, and since the utilization efficiency is low, the display portion of the light guide plate is illuminated with high brightness. For this purpose, there is a problem that power consumption is large and a high-luminance light source must be used.

さらに、特許文献２に開示された遊技機においても、ＬＥＤ光源からの距離によって到達する光量が異なるため、装飾部材からの反射光にムラが生じることは避けられなかった。   Furthermore, in the gaming machine disclosed in Patent Document 2, the amount of light that reaches the light source varies depending on the distance from the LED light source, and thus unevenness in the reflected light from the decorative member is inevitable.

上記の問題点に鑑み、遊技盤の役物部近傍を高輝度で光らせることができる装飾装置を提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a decoration device that can shine the vicinity of an accessory part of a game board with high brightness.

また本発明の別の目的として、本発明は、光源からの距離によらず、ほぼ均一な明るさで装飾物を光らせることができる装飾装置を提供することを目的とする。   Another object of the present invention is to provide a decoration device that can shine a decorative object with substantially uniform brightness regardless of the distance from the light source.

本発明のさらに別の目的として、光源からの出射光を効率よく利用可能な装飾装置を提供することを目的とする。   Still another object of the present invention is to provide a decoration device that can efficiently use light emitted from a light source.

本発明のさらに別の目的として、遊技盤を大型化することなく、遊技盤上の装飾物を光らせることができる装飾装置を提供することを目的とする。   Still another object of the present invention is to provide a decoration device that can shine a decoration on the game board without increasing the size of the game board.

上記の目的を達成するために、本発明に係る装飾装置は、遊技盤前面に配置される導光板であって、導光板の側面に設けられる入射面から入射した光が全反射によって内部を伝搬し、且つ光を視認可能な導光板の前面を経て外部へ拡散する拡散部を備える導光板と、遊技盤前面に配設される役物部の枠体と、役物部を遊技盤に固定する孔を形成する遊技盤内壁と、孔に内設される役物部外壁とからなる空隙に配置され、且つ入光面から入射する光束を導光板内へ導く導光部材と、導光部材の入光面に対向して配置される光源と、を有することを特徴とする。
このような構成とすることで、遊技盤と役物部との間の空隙を有効に活用して、光源からの光を導光板に導くことが可能となるため、遊技盤を大型化することなく、少ないスペースで装飾装置を配設することができる。また、役物部の近傍部分に拡散部を多数設けて、役物部の近傍部分を高輝度で光らせることも可能である。 In order to achieve the above object, a decoration device according to the present invention is a light guide plate disposed on the front surface of a game board, and light incident from an incident surface provided on a side surface of the light guide plate propagates through the interior by total reflection. In addition, the light guide plate having a diffusing portion that diffuses to the outside through the front surface of the light guide plate where light can be visually recognized, the frame of the accessory portion disposed on the front surface of the game board, and the accessory portion are fixed to the game board A light guide member that is disposed in a gap formed by an inner wall of a game board that forms a hole to be formed and an outer wall of an accessory part provided in the hole, and that guides a light beam incident from a light incident surface into the light guide plate, and a light guide member And a light source disposed opposite to the light incident surface.
By adopting such a configuration, it is possible to guide the light from the light source to the light guide plate by effectively utilizing the gap between the game board and the accessory part, and thus increase the size of the game board. The decoration device can be arranged in a small space. It is also possible to provide a number of diffusing parts in the vicinity of the accessory part so that the vicinity of the accessory part shines with high brightness.

また、導光部材の入光面は、正の屈折力を有し、且つ導光板の前面及び入射面にそれぞれ垂直な平面内における光束の幅が、入射面において、導光板の厚さ以下に集光されることが好ましい。
このような構成とすることにより、光源から照射される光を有効に利用できるとともに、拡散部により構成される図柄パターン又は文字などの装飾物を、光源からの距離によらず、ほぼ均一な明るさで光らせることができる。 The light incident surface of the light guide member has a positive refractive power, and the width of the light beam in a plane perpendicular to the front surface and the incident surface of the light guide plate is equal to or less than the thickness of the light guide plate at the incident surface. It is preferable that the light is condensed.
With such a configuration, the light emitted from the light source can be used effectively, and a decorative pattern such as a pattern pattern or characters formed by the diffusing unit can be brightened almost uniformly regardless of the distance from the light source. You can make it shine.

また、上記の平面内で、導光部材の厚さが、導光板の厚さ以上であり、且つ導光部材の厚さが、入光面の曲率半径の２倍以下であることが好ましい。導光部材の厚さが導光板の厚さ以上であることにより、光源からの照明光をより多く利用できるとともに、導光板に入射する光の入射角が広範囲にわたり、導光板内を様々な全反射角度で光が伝搬するため、より均一な照明が可能になる。また、導光部材の厚さが、入光面の曲率半径の２倍以下とすることで、導光部材の配置のために余分なスペースを必要としなくて済むためである。   Moreover, it is preferable that the thickness of the light guide member is equal to or greater than the thickness of the light guide plate and the thickness of the light guide member is equal to or less than twice the radius of curvature of the light incident surface within the plane. When the thickness of the light guide member is equal to or greater than the thickness of the light guide plate, more illumination light from the light source can be used, the incident angle of the light incident on the light guide plate is wide, and the entire light guide plate Since light propagates at the reflection angle, more uniform illumination is possible. Further, when the thickness of the light guide member is not more than twice the radius of curvature of the light incident surface, no extra space is required for the arrangement of the light guide member.

なお、導光部材は、複数の部材で構成してもよく、一方、単一の部材で構成してもよい。導光部材を複数の部材で構成すると、導光部材毎に光源の伝搬方向を変えることができるため、装飾の自由度を高めることが可能である。また、導光部材を複数種類の装飾装置に利用可能なように、規格化することもできるため、導光部材の低コスト化を図ることができる。一方、導光部材を単一部材で構成すると、役物部の形状に応じて導光部材を配置可能なように設計できるため、役物部の形状についてデザインの制限が少なくなり、装飾の自由度を高めることができる。   The light guide member may be composed of a plurality of members, or may be composed of a single member. When the light guide member is composed of a plurality of members, the propagation direction of the light source can be changed for each light guide member, so that the degree of freedom of decoration can be increased. In addition, since the light guide member can be standardized so that it can be used in a plurality of types of decoration devices, the cost of the light guide member can be reduced. On the other hand, if the light guide member is composed of a single member, it can be designed so that the light guide member can be arranged according to the shape of the accessory part. The degree can be increased.

さらに、本発明に係る遊技機は、上記の装飾装置を有することを特徴とする。   Furthermore, a gaming machine according to the present invention is characterized by having the above decoration device.

本発明によれば、遊技盤の役物部近傍を高輝度で光らせることができる装飾装置を提供することが可能となる。   ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the decoration apparatus which can shine the vicinity of the accessory part of a game board with high brightness | luminance.

また、光源からの距離によらず、ほぼ均一な明るさで装飾物を光らせることができる装飾装置を提供することが可能となる。   In addition, it is possible to provide a decoration device that can shine a decoration with almost uniform brightness regardless of the distance from the light source.

さらに、光源からの出射光を効率よく利用可能な装飾装置を提供することが可能となる。   Furthermore, it is possible to provide a decoration device that can efficiently use the light emitted from the light source.

さらに、遊技盤を大型化することなく、遊技盤上の装飾物を光らせることができる装飾装置を提供することが可能となる。   Furthermore, it is possible to provide a decoration device that can shine decorations on the game board without increasing the size of the game board.

In addition to the display device 11 and the accessory part 12, the decoration device 10 according to an example of the present invention is provided to change the intensity and color of the light.

次に、本発明の一例に係る装飾装置１０を備えた遊技盤２について説明する。
図２に、遊技盤２の正面図を示す。また、図３に、遊技盤２の分解斜視図を示す。
遊技盤２が備える装飾装置１０は、導光板２０と、複数の入光ユニット２１で構成される。導光板２０は、遊技盤２の前面に配設される。また、導光板２０は、光学プラスチック又は光学ガラスなどの光透過性材料で作製される。なお、導光板２０は、導光板２０と遊技盤２の間に空気層ができるように、導光板２０の端部近傍に配置された数箇所の固定点（図示せず）で遊技盤２にネジ止めされ、導光板２０内を光が全反射しつつ伝搬することが可能となっている。さらに、導光板２０の遊技盤２側の面（以下、導光板２０の裏面という）には、射出成形若しくはプリント加工などの微細加工によって、導光板２０内を伝搬する光を導光板２０の前面を経て外部へ拡散するための複数の拡散部３０が設けられる。この拡散部３０を、特に光らせたい図柄パターンとして配置することにより、遊技者にとって光って見える装飾物が形成される。 Next, the game board 2 provided with the decoration device 10 according to an example of the present invention will be described.
FIG. 2 shows a front view of the game board 2. FIG. 3 is an exploded perspective view of the game board 2.
The decoration device 10 included in the game board 2 includes a light guide plate 20 and a plurality of light incident units 21. The light guide plate 20 is disposed on the front surface of the game board 2. The light guide plate 20 is made of a light transmissive material such as optical plastic or optical glass. The light guide plate 20 is attached to the game board 2 at several fixed points (not shown) arranged near the end of the light guide plate 20 so that an air layer is formed between the light guide plate 20 and the game board 2. It is screwed so that light can propagate through the light guide plate 20 while being totally reflected. Further, on the surface of the light guide plate 20 on the game board 2 side (hereinafter referred to as the back surface of the light guide plate 20), the light propagating in the light guide plate 20 is transmitted to the front surface of the light guide plate 20 by fine processing such as injection molding or print processing. A plurality of diffusion portions 30 for diffusing to the outside through the above are provided. By arranging the diffusing portion 30 as a symbol pattern that is particularly desired to be lit, a decoration that looks shining for the player is formed.

導光板２０及び遊技盤２には、表示装置１１及び役物部１２を配置するために、中央部に孔が設けられている。そして、その孔の周囲に沿って、且つ役物部１２と、遊技盤２及び導光板２０との間に、導光板２０内を伝搬する照明光を供給する複数の入光ユニット２１が配置される。そして、入光ユニット２１から供給される照明光は、導光板２０内を放射状に拡がるように伝搬する。   In the light guide plate 20 and the game board 2, a hole is provided in the center for arranging the display device 11 and the accessory part 12. A plurality of light incident units 21 for supplying illumination light propagating in the light guide plate 20 are disposed along the periphery of the hole and between the accessory part 12 and the game board 2 and the light guide plate 20. The The illumination light supplied from the light incident unit 21 propagates in the light guide plate 20 so as to spread radially.

なお、図３において、説明の簡便化、及び明瞭化のために、入賞装置１３、風車１４、及びレール１５については省略し、また役物部１２の形状も簡略化している。   In FIG. 3, the winning device 13, the windmill 14, and the rail 15 are omitted for simplification and clarity of explanation, and the shape of the accessory part 12 is also simplified.

次に、入光ユニット２１の詳細について説明する。図４に、入光ユニット２１の分解斜視図を示す。また、図５に、図２の矢視Ａ−Ａにおける遊技盤２の断面図を示し、入光ユニット２１を、表示装置１１を支える表示装置フレーム１７に取り付けた様子を示す。   Next, details of the light incident unit 21 will be described. FIG. 4 shows an exploded perspective view of the light incident unit 21. 5 shows a cross-sectional view of the game board 2 taken along the line AA in FIG. 2, and shows a state where the light incident unit 21 is attached to the display device frame 17 that supports the display device 11. FIG.

入光ユニット２１は、複数の光源４０と、光源４０からの照明光を導光板２０に導くための導光部材４１と、光源を取り付けるための光源基板４２と、導光部材４１及び光源基板４２を固定し、入光ユニット２１を表示装置フレーム１７に取り付けるためのホルダ４３から構成される。   The light incident unit 21 includes a plurality of light sources 40, a light guide member 41 for guiding illumination light from the light sources 40 to the light guide plate 20, a light source substrate 42 for attaching the light sources, a light guide member 41, and a light source substrate 42. And a holder 43 for attaching the light incident unit 21 to the display device frame 17.

光源４０には、発光ダイオードを使用する。また、この発光ダイオードからの発光をできる限り導光部材４１に入射させるように、発光光の指向性が高いものを用いることが好ましい。なお、光源４０として、青色、緑色、赤色、白色などの各色の発光ダイオードを並べてもよい。複数色の発光ダイオードを使用すると、状況に応じて遊技者に見せる照明光の色を変えられるため、遊技者に対してよりインパクトの強い装飾を行うことができる。   As the light source 40, a light emitting diode is used. In addition, it is preferable to use a light emitting light having a high directivity so that light emitted from the light emitting diode is incident on the light guide member 41 as much as possible. As the light source 40, light emitting diodes of each color such as blue, green, red, and white may be arranged. When the light emitting diodes of a plurality of colors are used, the color of the illumination light to be shown to the player can be changed depending on the situation, so that the player can be decorated with a stronger impact.

また、光源４０として、光源を薄型化するために、有機ＥＬ発光素子や無機ＥＬ発光素子を代わりに用いてもよい。   As the light source 40, an organic EL light emitting element or an inorganic EL light emitting element may be used instead in order to make the light source thin.

導光部材４１は、光源４０からの照明光を導光板２０に導くためのものであり、光学プラスチックであるポリカーボネート（ＰＣ）又はポリメチルメタクリレート（ＰＭＭＡ）などの光学プラスチック材料を使用し、射出成形によって所定の形状に形成される。また、光学ガラスなどの光透過性材料を切削・研磨して作成してもよい。   The light guide member 41 is for guiding illumination light from the light source 40 to the light guide plate 20, and uses an optical plastic material such as polycarbonate (PC) or polymethyl methacrylate (PMMA), which is an optical plastic, and is injection molded. To form a predetermined shape. Further, it may be prepared by cutting and polishing a light transmissive material such as optical glass.

また図５に示すように、導光部材４１は、遊技盤２と役物部１２との空隙１８に配置される。詳しくは、遊技盤２との空隙１８を遊技者から見えないように隠蔽するとともに、装飾として機能する、遊技盤２の前面に配設される役物部枠体１２ａと、役物部１２を遊技盤２に挿通する孔を形成する遊技盤内壁２ａと、その孔に内設される役物部外壁１２ｂとからなる空隙１８に配置される。このように遊技盤２に役物部１２を取付ける際に必要な空隙を導光部材４１の先端が配置できる程度に設けるだけで、遊技盤２と役物部１２との間の空隙に導光部材の先端を導光板２０の入射面３１へ臨ませることができ、役物部外壁１２ｂ近傍に導光部材４１及び光源４０を配設可能とし、遊技盤２の遊技盤面領域を狭めることなく遊技台を形成することができる。
なお、導光部材４１の形状及び構造については、装飾装置１０全体の動作の説明とともに後述する。 As shown in FIG. 5, the light guide member 41 is disposed in the gap 18 between the game board 2 and the accessory part 12. More specifically, an accessory part frame 12a disposed on the front surface of the game board 2 and the accessory part 12 functioning as a decoration while concealing the gap 18 with the game board 2 from being visible to the player. The game board 2 is disposed in a space 18 formed by a game board inner wall 2a that forms a hole to be inserted into the game board 2 and an accessory part outer wall 12b provided in the hole. Thus, only by providing a gap necessary for attaching the accessory part 12 to the game board 2 to such an extent that the tip of the light guide member 41 can be arranged, the light guides to the gap between the game board 2 and the accessory part 12. The front end of the member can face the incident surface 31 of the light guide plate 20, and the light guide member 41 and the light source 40 can be disposed in the vicinity of the outer wall 12b of the accessory part, so that the game board surface area of the game board 2 is not reduced. A platform can be formed.
The shape and structure of the light guide member 41 will be described later together with the description of the operation of the decoration device 10 as a whole.

光源基板４２は、光源４０を固定するための樹脂製板状部材であり、導光部材４１と光源４０とが光学設計において決定される所定の位置関係を維持しつつ固定するための光源取り付け部４２ａと、長手方向の両端近傍に設けられた孔部４２ｂを備える。また、光源４０に電力を供給するための配線（図示せず）を備え、外部への接続のための図示しないコネクタを配設する。さらに、光源４０を駆動するための駆動回路を備えてもよい。   The light source substrate 42 is a resin plate-like member for fixing the light source 40, and a light source mounting portion for fixing the light guide member 41 and the light source 40 while maintaining a predetermined positional relationship determined in the optical design. 42a and a hole 42b provided near both ends in the longitudinal direction. Moreover, wiring (not shown) for supplying electric power to the light source 40 is provided, and a connector (not shown) for connection to the outside is provided. Furthermore, a drive circuit for driving the light source 40 may be provided.

ホルダ４３は、樹脂成形品であり、ホルダ４３の底部の両端近傍に設けた孔部４３ａと、光源基板４２の孔部４２ｂを貫通させたネジにより、導光部材４１をネジ止めすることにより、導光部材４１及び光源４０の位置関係を固定する。さらに、図４及び図５に示すように、ホルダ４３の底面の長手方向中央部に設けられた突起部４３ｂを、表示装置フレーム１７の取り付け用孔部に嵌合させ、且つホルダ４３の長手方向両端近傍で張り出すように設けられた孔部４３ｃにネジを通して表示装置フレーム１７にネジ止めすることにより、ホルダ４３を表示装置フレーム１７に固定する。表示装置フレーム１７には、全ての入光ユニット２１を取り付けることができるため、表示装置１１を遊技盤２に取り付けることにより、全ての入光ユニット２１を、導光板２０に対して同時に位置合わせすることができる。   The holder 43 is a resin molded product, and the light guide member 41 is screwed with a hole 43a provided near both ends of the bottom of the holder 43 and a screw passing through the hole 42b of the light source substrate 42. The positional relationship between the light guide member 41 and the light source 40 is fixed. Further, as shown in FIGS. 4 and 5, the protrusion 43 b provided at the center in the longitudinal direction of the bottom surface of the holder 43 is fitted into the mounting hole of the display device frame 17, and the longitudinal direction of the holder 43. The holder 43 is fixed to the display device frame 17 by screwing the display device frame 17 with screws through holes 43c provided so as to project in the vicinity of both ends. Since all the light incident units 21 can be attached to the display device frame 17, all the light incident units 21 are simultaneously aligned with the light guide plate 20 by attaching the display device 11 to the game board 2. be able to.

次に、本発明の一例に係る装飾装置１０の動作を説明する。
図６に、光源４０から出射した光が導光部材４１を経て導光板２０内を伝搬する様子を示す。 Next, the operation of the decoration device 10 according to an example of the present invention will be described.
FIG. 6 shows how light emitted from the light source 40 propagates through the light guide plate 20 through the light guide member 41.

ここで、本実施例に係る導光部材４１は、光源４０からの照明光を内部伝搬させ、導光板２０へ導く。そのために、導光部材４１は、光透過性材料であり、ｄ線屈折率１．５９を有するポリカーボネートで作成される。また、光源４０に対向して入光面５０が設けられる。そして、入光面５０に連続して、照明光が伝搬する導光部５３が形成される。導光部５３を経て、入光面５０と反対側の端部には、導光部材４１の光軸とのなす角が３６°となるように、反射面５１が形成される。すなわち、この反射面５１は、装飾装置１０を組み立てた状態において導光板２０の前面と５４°の角をなす。   Here, the light guide member 41 according to the present embodiment internally propagates the illumination light from the light source 40 and guides it to the light guide plate 20. Therefore, the light guide member 41 is a light transmissive material and is made of polycarbonate having a d-line refractive index of 1.59. Further, a light incident surface 50 is provided to face the light source 40. Then, a light guide portion 53 through which illumination light propagates is formed continuously with the light incident surface 50. A reflective surface 51 is formed at the end opposite to the light incident surface 50 through the light guide 53 so that the angle formed with the optical axis of the light guide member 41 is 36 °. That is, the reflection surface 51 forms an angle of 54 ° with the front surface of the light guide plate 20 in a state where the decoration device 10 is assembled.

入光面５０の反対側の端部近傍で、反射面５１と対向する面には、導光部材４１内を伝搬した光が出射する出射面５２が形成される。そして、導光部材４１は、出射面５２が、導光板２０の端部に設けられた入射面３１と近接するように配置される。   In the vicinity of the opposite end of the light incident surface 50, an exit surface 52 from which light propagating in the light guide member 41 exits is formed on the surface facing the reflective surface 51. The light guide member 41 is disposed such that the emission surface 52 is close to the incident surface 31 provided at the end of the light guide plate 20.

なお、導光板２０の前面及び導光板２０の入射面３１に垂直な平面（図６において紙面と平行な面）内において、導光部５３の短手方向の長さ（厚さ）の中心を通る線が光軸となる。また、入光面５０は、上記平面内において、光軸上に中心を有する曲率半径３ｍｍの凸状の円弧となり、一方、上記平面と直交し、入光面５０と平行な方向（図６において紙面と直交する方向、以下導光部材４１の幅方向という）に対しては有限の曲率半径を有さない、すなわち導光部材４１の幅方向には屈折力を有さないシリンドリカルレンズとして形成される。   In addition, the center of the length (thickness) in the short direction of the light guide portion 53 is within a plane perpendicular to the front surface of the light guide plate 20 and the incident surface 31 of the light guide plate 20 (a surface parallel to the paper surface in FIG. 6). The line that passes through is the optical axis. In addition, the light incident surface 50 is a convex arc having a radius of curvature of 3 mm centered on the optical axis in the plane, while being perpendicular to the plane and parallel to the light incident surface 50 (in FIG. 6). It is formed as a cylindrical lens that does not have a finite radius of curvature with respect to the direction orthogonal to the paper surface (hereinafter referred to as the width direction of the light guide member 41), that is, has no refractive power in the width direction of the light guide member 41. The

また導光部材４１は、入光面５０から、反対側の端部まで３７ｍｍの長さを有する。また、導光部材４１の幅方向の長さは６０ｍｍであり、導光部材４１の導光部５３の厚さは６ｍｍである。   The light guide member 41 has a length of 37 mm from the light incident surface 50 to the opposite end. The length of the light guide member 41 in the width direction is 60 mm, and the thickness of the light guide portion 53 of the light guide member 41 is 6 mm.

導光板２０は、厚さ２ｍｍのポリカーボネートで作成され、裏面側にエンボス加工により導光板２０内に凹状に形成された複数の拡散部３０を備える。拡散部３０は、約１０μｍから約１ｍｍの直径を有し、導光板２０の外部へ拡散させたい光量に応じて適宜設計される。直径が大きいほど、照射される照明光が多くなるため、外部へ拡散する光量も増大する。   The light guide plate 20 is made of polycarbonate having a thickness of 2 mm, and includes a plurality of diffusion portions 30 formed in a concave shape in the light guide plate 20 by embossing on the back surface side. The diffusing unit 30 has a diameter of about 10 μm to about 1 mm, and is appropriately designed according to the amount of light to be diffused to the outside of the light guide plate 20. The larger the diameter, the more illumination light is irradiated, so the amount of light that diffuses outside also increases.

光源４０として、発光輝度１０００ｍｃｄ、指向特性が輝度半減角３０°の発光ダイオード素子を使用する。また、発光ダイオード素子のカバー外径の直径は３ｍｍである。また光源４０を、入光面５０から約１ｍｍの距離で、且つ導光部材４１の光軸上に配置する。なお、通常は１枚の導光部材４１に対して、複数の光源が使用され、各光源は入光面５０に対して等距離で配置されるが、ここでは簡単化のため１個の光源についてのみ説明する。   As the light source 40, a light-emitting diode element having an emission luminance of 1000 mcd and a directivity characteristic having a luminance half angle of 30 ° is used. The diameter of the cover outer diameter of the light emitting diode element is 3 mm. Further, the light source 40 is disposed on the optical axis of the light guide member 41 at a distance of about 1 mm from the light incident surface 50. Normally, a plurality of light sources are used for one light guide member 41, and each light source is arranged at an equal distance with respect to the light incident surface 50. Here, for simplicity, one light source is used. Only will be described.

図６に示すように、光源４０から発した照明光は、導光部材４１の入光面５０を通って導光部材４１の内部を通り、反射面５１に到達する。そして、照明光は、反射面５１で反射されて出射面５２へ向かう。導光部材４１の出射面５２を出射した照明光は、導光板２０の入射面３１を通じて導光板２０内へ入射する。また、その照明光は、入光面５０及び光源４０として使用した発光ダイオード素子が有するレンズのレンズ作用により、導光板２０の入射面３１近傍で最も収束され、照明光の光束の幅は、導光板２０の前面及び入射面３１に垂直な平面内において、入射面３１での導光板２０の厚さ以下となる。そして、導光板２０内を全反射によって伝搬する。ここで、導光板２０内を伝搬する照明光が拡散部３０に当たると、照明光は拡散されて、その大部分は導光板２０の前面に対して大きな角度を有する光となり、導光板２０の前面で全反射せずに外部へ出射する。一方、拡散部３０に当たらない照明光は、そのまま全反射を繰り返して導光板２０内を伝搬する。そのため、遊技者には、拡散部３０が発光しているように見える。拡散部３０をユーザに見せたい形状となるように配置することで、所望の装飾を行うことができる。また、照明光は、拡散部３０に当たらない限り、導光板２０内を全反射によって伝搬するため、伝搬損失がなく、導光板２０の入射面３１からの距離に依存することなく、すなわち光源４０からの距離に依存することなく、遊技盤２全体に照明光を行き渡らせることができる。したがって、遊技盤２上の場所に関わらず、ほぼ同じ明るさで拡散部３０を光らせることができる。一方、拡散部３０が形成されていない領域については、遊技者は遊技盤２を直接見ることができる。そこで、光らせる必要のない図柄については、拡散部３０と重ならないように遊技盤２上に描いておくことで、遊技者に視認させることができる。   As shown in FIG. 6, the illumination light emitted from the light source 40 passes through the light incident surface 50 of the light guide member 41, passes through the inside of the light guide member 41, and reaches the reflection surface 51. Then, the illumination light is reflected by the reflection surface 51 and travels toward the emission surface 52. The illumination light that has exited the exit surface 52 of the light guide member 41 enters the light guide plate 20 through the entrance surface 31 of the light guide plate 20. Further, the illumination light is most converged in the vicinity of the incident surface 31 of the light guide plate 20 by the lens action of the light emitting diode element used as the light incident surface 50 and the light source 40, and the width of the light flux of the illumination light is guided. In the plane perpendicular to the front surface and the incident surface 31 of the optical plate 20, the thickness is equal to or less than the thickness of the light guide plate 20 at the incident surface 31. Then, the light propagates through the light guide plate 20 by total reflection. Here, when the illumination light propagating in the light guide plate 20 hits the diffusion unit 30, the illumination light is diffused, and most of the light becomes light having a large angle with respect to the front surface of the light guide plate 20. And exits without being totally reflected. On the other hand, the illumination light that does not strike the diffusing unit 30 repeats total reflection as it is and propagates through the light guide plate 20. Therefore, it seems to the player that the diffusing unit 30 emits light. By arranging the diffusing unit 30 so as to have a shape that the user wants to show, a desired decoration can be performed. Further, since the illumination light propagates through the light guide plate 20 by total reflection unless it hits the diffusing portion 30, there is no propagation loss and does not depend on the distance from the incident surface 31 of the light guide plate 20, that is, the light source 40. The illumination light can be spread throughout the game board 2 without depending on the distance from the game board 2. Therefore, regardless of the location on the game board 2, the diffusing unit 30 can be illuminated with substantially the same brightness. On the other hand, the player can see the game board 2 directly in the area where the diffusion part 30 is not formed. Therefore, a symbol that does not need to be lit can be visually recognized by the player by drawing it on the game board 2 so as not to overlap the diffusion unit 30.

この様子を図７に示す。例えば、導光板２０において、複数の拡散部３０を、アルファベットの‘Ａ’の形に配置する。すると、光源４０からの照明光が、導光部材４１を経て入射面３１から導光板２０に入射して、拡散部３０で拡散されることにより、この‘Ａ’の文字を光らせる。拡散部３０を多数集中して配置することによって装飾物を形成すれば、その集中しているところから拡散される照明光の光量が大きくなるため、高輝度で光る装飾物を実現することができる。なお、図７においては、簡略化のために遊技盤２及び導光板２０を矩形状としているが、実際には役物部の形状に合わせて、入射面３１が円弧形状または多角形状となっている。   This is shown in FIG. For example, in the light guide plate 20, the plurality of diffusion portions 30 are arranged in the form of an alphabet “A”. Then, the illumination light from the light source 40 enters the light guide plate 20 through the light entrance member 31 through the light guide member 41 and is diffused by the diffusion unit 30, thereby causing the letter “A” to shine. If a decorative object is formed by arranging a large number of diffuser portions 30 in a concentrated manner, the amount of illumination light diffused from the concentrated area increases, so that a decorative object that shines with high brightness can be realized. . In FIG. 7, the game board 2 and the light guide plate 20 are rectangular for simplification, but in practice, the incident surface 31 has an arc shape or a polygonal shape according to the shape of the accessory part. Yes.

さらに、上述したように、導光部材４１の入光面５０は、厚さ方向に正の屈折力を有し、幅方向には屈折力を有さないシリンドリカル面として構成されている。そのため、導光部材４１の厚み方向に拡散する光を、入光面５０を平面状に形成した場合よりも多く導光部材４１内に導くことが可能であり、光源４０からの照明光をより効率よく利用することができる。一方、導光部材４１の幅方向（光源を複数使用する場合、光源の並び方向でもある）には、照明光はそのまま拡散するため、導光板２０の入射面３１において照明光が一様となり、光源の配置に対応した照明光の強度分布が生じることを防止できる。   Furthermore, as described above, the light incident surface 50 of the light guide member 41 is configured as a cylindrical surface having a positive refractive power in the thickness direction and no refractive power in the width direction. Therefore, it is possible to guide more light diffusing in the thickness direction of the light guide member 41 into the light guide member 41 than when the light incident surface 50 is formed in a flat shape, and more illumination light from the light source 40 can be obtained. It can be used efficiently. On the other hand, in the width direction of the light guide member 41 (in the case where a plurality of light sources are used, it is also the arrangement direction of the light sources), the illumination light is diffused as it is, so that the illumination light is uniform on the incident surface 31 of the light guide plate 20, It is possible to prevent the intensity distribution of illumination light corresponding to the arrangement of the light sources.

また、導光部材４１に入射した照明光の光束が、導光板２０の入射面３１において、導光板２０の入射面３１における厚み以下に集光されることが好ましい。このように照明光を集光することで、導光部材４１に入射した照明光のほぼ全部を、装飾に利用することができるためである。このような集光を行うために、例えば光源４０の像を導光板２０の入射面３１上に結像するように、導光部材４１の入光面５０のレンズの屈折力を設計すればよい。このような結像関係を満たす配置は、近軸光学で使用されるアッベの不変量などの公式を用いて当業者が容易に決定することができる。また、反射面５１を凹面鏡若しくは凸面鏡に形成して光学屈折力を持たせ、入光面５０と協働する光学系を形成し、光源４０の像を導光板２０の入射面３１上に結像させてもよい。   In addition, it is preferable that the illumination light beam incident on the light guide member 41 is condensed on the incident surface 31 of the light guide plate 20 to be equal to or less than the thickness of the incident surface 31 of the light guide plate 20. This is because almost all of the illumination light incident on the light guide member 41 can be used for decoration by condensing the illumination light in this way. In order to perform such condensing, for example, the refractive power of the lens on the light incident surface 50 of the light guide member 41 may be designed so that an image of the light source 40 is formed on the incident surface 31 of the light guide plate 20. . An arrangement satisfying such an imaging relationship can be easily determined by those skilled in the art using formulas such as Abbe's invariant used in paraxial optics. Further, the reflecting surface 51 is formed as a concave mirror or a convex mirror so as to have optical refractive power, and an optical system that cooperates with the light incident surface 50 is formed, and an image of the light source 40 is formed on the incident surface 31 of the light guide plate 20. You may let them.

なお、上記の構成においては、光源４０を導光部材４１の光軸上に配置したが、反射面５１の角度及び入光面５０の曲率半径を適切に設計することにより、光軸外に配置することもできる。また、入光面５０を、光軸から離れるにつれて、曲率が緩やかになる非球面で形成してもよい。このような非球面を使用することで、必要に応じて球面収差などの収差を低減することができる。さらに、反射面５１を直線上に形成する代わりに、折線状、円弧状、若しくは自由曲線で形成することもできる。この反射面５１の形状は、遊技盤２、役物部１２などのデザインに応じて決まる、入光ユニット２１を配置することが可能なスペースの大きさに合わせて導光部材４１を最適化する際に、導光部材４１の長さ、厚み、材質に基づいて適切な形状に設計することができる。   In the above configuration, the light source 40 is disposed on the optical axis of the light guide member 41. However, by appropriately designing the angle of the reflection surface 51 and the radius of curvature of the light incident surface 50, the light source 40 is disposed outside the optical axis. You can also Further, the light incident surface 50 may be formed of an aspherical surface whose curvature becomes gentler as it moves away from the optical axis. By using such an aspherical surface, aberrations such as spherical aberration can be reduced as necessary. Furthermore, instead of forming the reflecting surface 51 on a straight line, it may be formed in a polygonal line shape, an arc shape, or a free curve. The shape of the reflective surface 51 is determined according to the design of the game board 2, the accessory part 12, etc., and the light guide member 41 is optimized in accordance with the size of the space where the light incident unit 21 can be arranged. In this case, the light guide member 41 can be designed into an appropriate shape based on the length, thickness, and material.

また、反射面５１は、全反射面とすることが好ましい。反射面５１での照明光のエネルギーのロスを生じさせず、より効率よく照明光を利用できるためである。さらに、光学設計上、反射面５１への照明光の入射角による制約から、一部領域のみ全反射にすることが可能な場合には、全反射可能な領域については反射面５１の外部を空気層で構成して全反射面とし、全反射にすることが不可能な領域については、反射面に金属膜を蒸着して通常の反射面を形成するようにしてもよい。   The reflecting surface 51 is preferably a total reflection surface. This is because the illumination light can be used more efficiently without causing a loss of illumination light energy on the reflection surface 51. Further, in the optical design, when it is possible to make total reflection only in a partial area due to the restriction due to the incident angle of the illumination light to the reflection surface 51, the outside of the reflection surface 51 is air-exposed for the total reflection area. For a region constituted by layers to be a total reflection surface and cannot be totally reflected, a normal reflection surface may be formed by depositing a metal film on the reflection surface.

導光部材４１の厚さは、導光板２０の厚さよりも厚いことが好ましい。導光板２０内を全反射により伝搬可能な全てのモードに対応する照明光を導光板２０に供給することができるからである。一方、導光部材４１の厚さは、入光面５０に設けられるレンズの曲率半径の２倍以下であることが好ましい。曲率半径の２倍より厚くしても、入光面５０の端部近傍ではレンズ面を形成することができない。したがって、そのようなレンズ面を有さないところから導光部材４１内に入射した照明光は、反射面５１まで到達せずに導光部材４１から出射してしまい、利用可能な照明光の光量を増やすことができないためである。   The light guide member 41 is preferably thicker than the light guide plate 20. This is because illumination light corresponding to all modes that can propagate through the light guide plate 20 by total reflection can be supplied to the light guide plate 20. On the other hand, the thickness of the light guide member 41 is preferably not more than twice the radius of curvature of the lens provided on the light incident surface 50. Even if it is thicker than twice the radius of curvature, a lens surface cannot be formed in the vicinity of the end of the light incident surface 50. Therefore, the illumination light that has entered the light guide member 41 from a place that does not have such a lens surface is emitted from the light guide member 41 without reaching the reflection surface 51, and the amount of illumination light that can be used. It is because it cannot increase.

なお、本発明に係る装飾装置は、上記の例に限られない。例えば、入光ユニットの一部を反転し、遊技盤２中央の表示装置１１が配置される内側へ向けて光を出射するように構成すれば、表示装置１１に表示される内容と同期して照明光の輝度を変化させることにより、表示装置１１の表示内容と照明光とを重畳してインパクトの強い装飾を行うことができる。また、図８に示すように、役物部１２の形状に合わせて遊技盤２に取り付けられるように、導光部材４１を一部材として構成することもできる。このような導光部材４１は、金型を所望の形状に基づいて適切に設計することにより、光学プラスチックを射出成形することによって作成できる。このように導光部材４１を一部材として構成すると、役物の形状設計の自由度を高めることができ、且つ取り付け時に複数のユニットの位置決めを行う必要がないので、導光部材４１の取り付けを容易に行うことができる。   The decoration device according to the present invention is not limited to the above example. For example, if a part of the light incident unit is inverted so that light is emitted toward the inside where the display device 11 at the center of the game board 2 is arranged, the content displayed on the display device 11 is synchronized. By changing the luminance of the illumination light, the display content of the display device 11 and the illumination light can be superimposed to perform decoration with a strong impact. Moreover, as shown in FIG. 8, the light guide member 41 can also be comprised as one member so that it may be attached to the game board 2 according to the shape of the accessory part 12. FIG. Such a light guide member 41 can be produced by injection-molding optical plastic by appropriately designing a mold based on a desired shape. If the light guide member 41 is configured as one member in this way, the degree of freedom in the shape design of the accessory can be increased, and it is not necessary to position a plurality of units at the time of attachment. It can be done easily.
