Description

本発明は、パチンコ機等の弾球遊技機の技術分野に属する。 The present invention belongs to the technical field of ball game machines such as pachinko machines.

パチンコ機等の弾球遊技機は遊技盤を必須としている。遊技盤には入賞口が設けられ、また遊技釘が植設されるのが普通である。その遊技盤を透明な合成樹脂板とし、遊技盤の背後に表示装置を配置して、遊技盤の広い範囲を表示に用いる弾球遊技機が知られている。
特開２００５−３１２４７１号公報 A ball game machine such as a pachinko machine requires a game board. The game board is usually provided with a winning opening, and game nails are usually planted. 2. Description of the Related Art There is known a ball game machine in which the game board is a transparent synthetic resin plate and a display device is arranged behind the game board so that a wide range of the game board is used for display.
JP-A-2005-312471

弾球遊技機の背面部には、上述の表示装置、発射装置、払出装置、モータやソレノイド等のアクチュエータ、それらの制御装置等の様々な電気的な装置が取り付けられている。これらの電気的な装置が熱を発生するが、遊技機設置島に設置された弾球遊技機の背面側はほぼ閉じた空間になっているために熱がこもって、弾球遊技機の背面側は比較的高温になる。一方、遊技店では空調が行われるのが普通であるから、弾球遊技機の前面側は背面側に比べれば大幅に低温である。 Various electrical devices such as the above-described display device, launch device, payout device, actuators such as motors and solenoids, and control devices thereof are attached to the rear surface of the ball game machine. Although these electrical devices generate heat, the back side of the ball and ball machine installed on the island where the game machine is installed is a closed space, so the heat accumulates and the back of the ball and ball machine is The side becomes relatively hot. On the other hand, since air conditioning is usually performed at a game store, the front side of the ball game machine is significantly cooler than the back side.

その温度差が遊技盤の前後で顕著になるため、遊技盤を透明な合成樹脂板とした場合には、相対的に高温になる遊技盤の背面での熱膨張が前面よりも大きくなって遊技盤が反るという問題がある。 Since the temperature difference becomes significant before and after the game board, when the game board is made of a transparent synthetic resin plate, the thermal expansion at the back of the game board, which is relatively hot, is larger than that at the front and the game There is a problem that the board warps.

アクリル樹脂の熱膨張係数は、約７×１０^-5ｃｍ／ｃｍ・ｄｅｇ．であるから、アクリル樹脂製の遊技盤の前後面での温度差が３０ｄｅｇ．とすれば、１辺が約５０ｃｍの遊技盤の場合、前後面では各辺につき１．０５×１０^-1ｃｍ、つまり１．０５ｍｍの膨張差が生じる。 The thermal expansion coefficient of the acrylic resin is about 7 × 10 ⁻⁵ cm / cm · deg. Therefore, the temperature difference between the front and rear surfaces of the acrylic resin game board is 30 deg. Then, in the case of a game board having one side of about 50 cm, an expansion difference of 1.05 × 10 ⁻¹ cm, that is, 1.05 mm is generated for each side on the front and rear surfaces.

その結果、遊技盤は前面が凹曲面となるように反り変形する。これに伴って、各遊技釘は、図３（ａ）に例示の状態から同図（ｂ）に例示の状態へと、隣り合う遊技釘３０同士の頭部３０ａ間の距離が縮まるように変位してしまう。なお、図３（ｂ）は遊技釘３０の変位を誇張してある。 As a result, the game board is warped and deformed so that the front surface becomes a concave curved surface. Accordingly, the game nails are displaced from the state illustrated in FIG. 3A to the state illustrated in FIG. 3B so that the distance between the heads 30a of the adjacent game nails 30 is reduced. Resulting in. In FIG. 3B, the displacement of the game nail 30 is exaggerated.

釘調節は営業を開始する前の遊技機を停止した状態で行うので、釘調節後に遊技釘が上記のように変位するのは釘調節を変更したのと同じことになり、いわゆる割数が所期の通りにならないという問題が生じていた。 Since the nail adjustment is performed with the gaming machine stopped before starting operation, the displacement of the game nail as described above after the nail adjustment is the same as the change of the nail adjustment. There was a problem that it did not follow the schedule.

請求項１記載の遊技盤は、透明な合成樹脂製の第１層板と透明な合成樹脂製の第２層板とを透明な粘着剤を介して接合した積層構造を有することを特徴とする。
粘着剤は、接着剤のように固化してしまうわけではなく、固化した接着剤よりも柔らかい素材であるため、接着剤により貼り合わせた場合のように２層の位置関係が完全に固定されるわけではない。このため、第１層板（例えば遊技盤の表面）と第２層板（例えば遊技盤の裏面）とに温度差があって両者の熱膨張量に差が生じた場合、粘着剤の層が第１層板と第２層板との線膨張差を吸収することによって、遊技盤の反りを防止できる。よって、隣り合う遊技釘同士の頭部間の距離が縮まるような変位は生じないから、これが原因となっての割数が期待通りにならないという問題も生じない。 The game board according to claim 1 has a laminated structure in which a transparent synthetic resin first layer board and a transparent synthetic resin second layer board are joined via a transparent adhesive. .
The pressure-sensitive adhesive is not solidified like an adhesive, but is a softer material than the solidified adhesive, so that the positional relationship between the two layers is completely fixed as in the case of bonding with the adhesive. Do not mean. For this reason, when there is a temperature difference between the first layer board (for example, the front surface of the game board) and the second layer board (for example, the back surface of the game board), and the difference in thermal expansion between the two layers, By absorbing the difference in linear expansion between the first layer plate and the second layer plate, warping of the game board can be prevented. Therefore, there is no displacement that shortens the distance between the heads of adjacent game nails, so that the problem that the divisor due to this does not become as expected does not occur.

第１層板、第２層板となる透明な合成樹脂としてはアクリル樹脂やポリカーボネート樹脂が例示されるが、透明であって遊技盤としての剛性や表面の平滑性が満たされるなら、これら限らず使用できる。第１層板と第２層板とは同材質であってもよいし、異なる材質であってもよい。 Examples of the transparent synthetic resin to be the first layer plate and the second layer plate include acrylic resins and polycarbonate resins, but these are not limited as long as they are transparent and satisfy the rigidity and surface smoothness as a game board. Can be used. The first layer plate and the second layer plate may be made of the same material or different materials.

第１層板と第２層板とを接合するための透明な粘着剤はアクリル系、シリコーン系、ウレタン系、ゴム系、スチレンエラストマー系等、どのような粘着剤でもよいが、透明性、耐久性の観点からアクリル系やシリコーン系が好ましい。 The transparent adhesive for joining the first layer plate and the second layer plate may be any adhesive such as acrylic, silicone, urethane, rubber, styrene elastomer, etc., but it is transparent and durable. From the viewpoint of properties, acrylic and silicone are preferred.

粘着剤は、請求項２記載のように、透明な樹脂フィルムに担持されていてもよい。つまり、ＰＥＴ等の樹脂フィルムの両面に粘着剤の層を設けたものを第１層板と第２層板とに挟んで、第１層板と第２層板とを接合する。このような樹脂フィルム自体は、合わせガラス用の中間膜として公知であるが、粘着剤の表面を剥離材（例えば剥離紙）で覆っておいて、使用時にこれを剥がすようにすれば、保管や作業を行いやすいという利点がある。 The pressure-sensitive adhesive may be carried on a transparent resin film as described in claim 2. That is, the first layer plate and the second layer plate are joined by sandwiching a layer of adhesive such as PET on both sides of the first layer plate and the second layer plate. Such a resin film itself is known as an intermediate film for laminated glass. However, if the surface of the pressure-sensitive adhesive is covered with a release material (for example, release paper) and peeled off at the time of use, There is an advantage that it is easy to work.

次に、本発明の実施例等により発明の実施の形態を説明する。なお、本発明は下記の実施例等に限定されるものではなく、本発明の要旨を逸脱しない範囲でさまざまに実施できることは言うまでもない。
［実施例］
図１に示すように、本実施例の遊技盤１は、アクリル樹脂製の第１層板２とアクリル樹脂製の第２層板３とを透明粘着剤４を介して接合した積層構造をしている。なお、遊技釘５は第１層板２に（透明粘着剤４に達しない深さで）植設される。透明粘着剤４は、特開２００５−６８７７４号公報に記載されている、アクリル酸エステル共重合体と硬化剤と光重合開始剤からなるアクリル系の粘着剤の透明粘着シートを使用した。 Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example]
As shown in FIG. 1, the game board 1 of this embodiment has a laminated structure in which a first layer plate 2 made of acrylic resin and a second layer plate 3 made of acrylic resin are joined via a transparent adhesive 4. ing. The game nail 5 is planted on the first layer board 2 (at a depth that does not reach the transparent adhesive 4). As the transparent adhesive 4, an acrylic adhesive transparent adhesive sheet composed of an acrylic ester copolymer, a curing agent, and a photopolymerization initiator described in JP-A-2005-68774 was used.

遊技盤１には、図２に示すように、ガイドレール６、７、可変入賞装置８、ゲート９、大入賞口１０、普通入賞口１１、庇部材１２、ステージ１３等が取り付けられ、遊技釘５や風車１４が打ち付けられている。 As shown in FIG. 2, the game board 1 is provided with guide rails 6 and 7, a variable winning device 8, a gate 9, a big winning port 10, a normal winning port 11, a saddle member 12, a stage 13, and the like. 5 and a windmill 14 are hit.

庇部材１２とステージ１３とに挟まれた主表示領域１５には、遊技釘５が打ち付けられておらず、他の装置類も配されていない。この主表示領域１５は、遊技盤１の背後に配された表示装置（図示しない）による図柄やキャラクタの表示を良好に視認させるための領域である。なお、表示装置による表示は主表示領域１５のみで行われるわけではなく、主表示領域１５から外れた部分でも行われる。 In the main display area 15 sandwiched between the scissors member 12 and the stage 13, the game nail 5 is not driven and no other devices are arranged. The main display area 15 is an area for satisfactorily recognizing the display of symbols and characters by a display device (not shown) disposed behind the game board 1. Note that the display by the display device is not performed only in the main display area 15, but also in a portion outside the main display area 15.

上述の通り、本実施例の遊技盤１は、透明なアクリル樹脂製の第１層板２と透明なアクリル樹脂製の第２層板３とを透明な粘着剤４を介して接合した積層構造を有している。
粘着剤４は、接着剤のように固化してしまうわけではなく、固化した接着剤よりも柔らかい素材であるため、接着剤により貼り合わせた場合のように第１層板２と第２層板３との位置関係が完全に固定されるわけではない。このため、遊技盤１の背面が相対的に高温で前面が相対的に低温と、第１層板２と第２層板３とに温度差があって両者の熱膨張量に差が生じた場合、粘着剤４の層が第１層板２と第２層板３との線膨張差を吸収することによって、遊技盤１の反りを防止できる。よって、隣り合う遊技釘５同士の頭部間の距離が縮まるような変位は生じないから、これが原因となっての割数が期待通りにならないという問題も生じない。 As described above, the gaming board 1 of this embodiment has a laminated structure in which the first layer plate 2 made of transparent acrylic resin and the second layer plate 3 made of transparent acrylic resin are joined via the transparent adhesive 4. have.
The pressure-sensitive adhesive 4 does not solidify like an adhesive, but is a softer material than the solidified adhesive, so that the first layer plate 2 and the second layer plate are the same as when bonded together with an adhesive. The positional relationship with 3 is not completely fixed. For this reason, the back surface of the game board 1 is relatively high temperature and the front surface is relatively low temperature, and there is a temperature difference between the first layer plate 2 and the second layer plate 3, resulting in a difference in the amount of thermal expansion between the two. In this case, the warp of the game board 1 can be prevented by the layer of the pressure-sensitive adhesive 4 absorbing the difference in linear expansion between the first layer plate 2 and the second layer plate 3. Therefore, there is no displacement that reduces the distance between the heads of the adjacent game nails 5, so that the problem that the quotient due to this does not become as expected does not occur.

なお、粘着剤４による接合では、第１層板２と第２層板３との位置関係が完全には固定されないといっても、第１層板２と第２層板３との線膨張差（［発明が解決しようとする課題］で例示した１．０ｍｍ程度の線膨張差）を吸収し得る程度には可変ということであり、遊技盤１として成り立たないほどに第１層板２と第２層板３の位置関係を変化できるわけではない。 It should be noted that the linear expansion between the first layer plate 2 and the second layer plate 3 can be said to be performed even if the positional relationship between the first layer plate 2 and the second layer plate 3 is not completely fixed in the bonding with the adhesive 4. The difference (the linear expansion difference of about 1.0 mm exemplified in [Problems to be Solved by the Invention]) is variable to the extent that it can be absorbed, and the first layer board 2 cannot be realized as the game board 1. The positional relationship of the second layer plate 3 cannot be changed.

また、実施例では遊技盤１を第１層板２と第２層板３との２層構造にしているが、これを３層以上の構造にすることもできる。 Further, in the embodiment, the game board 1 has a two-layer structure of the first layer board 2 and the second layer board 3, but this can also be a structure of three or more layers.
