Abstract

<P>PROBLEM TO BE SOLVED: To reduce the quantity of work and working cost of machining of a game board made of a synthetic resin. <P>SOLUTION: The game board 1 is made of the synthetic resin, and the plate thickness of at least a range where game pins 20 are disposed is uniform. The game board 1 is manufactured by the procedure of forming openings (attaching holes 6a, 7a, 14a and 15a and an out hole 5) passing through between front and back surfaces, a groove for dropping game balls which pass through an out hole 61 and a dowel hole for positioning, etc., by molding of solidifying the synthetic resin inside a die and drilling prepared holes 25 for forcibly fitting the game pins 20 thereafter. Thus, the need of machining the attaching holes 6a, 7a, 14a and 15a and the out hole 5, etc., is eliminated, and the quantity of work of the machining is reduced and the working cost is reduced as well accordingly. Additionally, by forming not only such openings but also notches, recesses and grooves, etc., together with the openings, the quantity of work and the work cost of the machining can be reduced further. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、弾球遊技機の遊技盤の技術分野に属する。   The present invention belongs to the technical field of game boards for ball game machines.

パチンコ機等の弾球遊技機の遊技盤には遊技球の進路を変化させるための遊技釘(障害釘とも言う)が打ち付けられるのが一般的である。
そのため、遊技盤を合成樹脂製にした場合は、釘打ち可能にするための構成を要求される。
In general, game nails (also referred to as obstacle nails) for changing the course of the game ball are hit on a game board of a ball game machine such as a pachinko machine.
Therefore, when the game board is made of synthetic resin, a configuration for enabling nailing is required.

例えばガスカウンタプレッシャー法による発泡成形にて釘打ちを可能にする技術(一例として特開平11−099244号公報)や押出成形した板材に釘用の下穴をドリル加工する技術も知られている。
特開平11−099244号公報
For example, a technique that enables nailing by foaming by a gas counter pressure method (for example, Japanese Patent Application Laid-Open No. 11-099244) and a technique of drilling a pilot hole for a nail in an extruded plate material are also known.
Japanese Patent Laid-Open No. 11-099244

特許文献1に開示されている発泡成形の場合、釘打ちはできるものの、内部構造がスポンジ状であることから遊技釘を保持する力(拘束力)が不十分であり、遊技球の衝突で遊技釘がぐらつくおそれがある。特に、いわゆる釘調整のためのハンマーに耐えきれずにぐらついたり抜け落ちたりするおそれがある。   In the case of foam molding disclosed in Patent Document 1, although nailing can be performed, the internal structure is sponge-like, so that the force (restraint force) for holding the game nail is insufficient, and the game ball is hit by a collision. There is a risk that the nail will wobble. In particular, there is a risk of wobbling or falling without being able to withstand a hammer for so-called nail adjustment.

一方、押出成形した板材に釘用の下穴をドリル加工して、この下穴に遊技釘を圧入する構成であると、拘束力は十分であり上述のぐらつき等のおそれはない。
しかしながら、板材を加工するので、釘用の下穴だけでなく入賞装置や表示装置のための開口も機械加工しなければならず、機械加工の作業量が多く、それに応じて加工費も高かった。
On the other hand, when the prepared hole is drilled into the extruded plate material and the game nail is press-fitted into the prepared hole, the restraining force is sufficient and there is no fear of the above-mentioned wobble or the like.
However, since the plate material is processed, not only the pilot holes for nails but also the openings for the prize-winning device and the display device must be machined, and the amount of machining work is large, and the processing cost is accordingly high. .

請求項1記載の遊技盤の製造方法は、合成樹脂製で少なくとも遊技釘が配設される範囲は板厚が均等な遊技盤を製造するに当たって、金型内で合成樹脂を固化させる成形により表裏面間に貫通する開口を形成し、その後に前記遊技釘を圧入するための下穴をドリル加工することを特徴とする。   The method of manufacturing a game board according to claim 1 is a method of producing a game board made of synthetic resin and having at least a game nail in which the thickness of the game nails is uniform by molding the synthetic resin in a mold. An opening penetrating between the back surfaces is formed, and then a pilot hole for press-fitting the game nail is drilled.

この製造方法で製造される遊技盤は、合成樹脂製で少なくとも遊技釘が配設される範囲は板厚が均等になっている。
この遊技釘が配設される範囲とは、例えば複数本の遊技釘(但し、1直線上にならないような配置)からなる集合があるとして、その集合の中で外側に位置するもの同士をつなぐ線を輪郭とするような範囲である。従って、このような範囲では遊技釘間の板厚が均一になる。なお、均等にする部分の板厚は、遊技釘の打ち込み深さに応じて(釘の先端部が突出しないように)設定すればよい。
The game board manufactured by this manufacturing method is made of synthetic resin and has a uniform thickness at least in a range where game nails are disposed.
The range in which the game nails are arranged is, for example, that there is a set of a plurality of game nails (however, not arranged on one straight line), and the ones located outside in the set are connected to each other. The range is such that the line is the outline. Therefore, in such a range, the board thickness between the game nails becomes uniform. In addition, what is necessary is just to set the board thickness of the part to equalize according to the driving depth of a game nail (so that the front-end | tip part of a nail does not protrude).

言うまでもないが、遊技釘を圧入するためのボス等を遊技釘に対応させて例えば点々と配置した構成は本発明では排除される。
また、このような範囲が複数箇所になる場合もあるが、その場合は各範囲毎に板厚が均等ということである。勿論、各範囲同士でも板厚を均等にできるし、その方が好ましい。さらには各範囲同士の間も板厚を均等にするのが望ましい。
Needless to say, the present invention excludes a configuration in which, for example, bosses for press-fitting game nails are arranged in correspondence with the game nails.
In addition, there are cases where such a range is a plurality of places, in which case the plate thickness is equal for each range. Of course, the plate thickness can be made uniform in each range, and that is preferable. Furthermore, it is desirable to make the plate thickness uniform between the ranges.

このように板厚を均等にする範囲には、遊技釘が配設されない部分が含まれても差し支えはなく、例えば遊技領域に対応する部分の板厚を均等にしてもよいし、遊技盤全体の板厚を均等にしてもよい。但し、遊技盤には例えばアウト球を誘導するための溝が設けられるのが普通であり、遊技盤を弾球遊技機本体に取り付けるための凹みが設けられることもあるから、これらの溝等を除いて遊技領域に対応する部分或いは遊技盤全体の板厚を均等にすることになる。   In this way, the range in which the plate thickness is made uniform may include a portion where the game nail is not disposed. For example, the plate thickness of the portion corresponding to the game area may be made uniform, or the entire game board The plate thickness may be made uniform. However, for example, the game board is usually provided with grooves for guiding out balls, and a recess for attaching the game board to the main body of the ball game machine may be provided. Except for this, the thickness corresponding to the game area or the entire game board is made uniform.

遊技盤を形成する合成樹脂の種類、組成、性状等は特に限定されない。透明であってもよいし不透明であってもよい。
金型内で合成樹脂を固化させる成形方法としては、射出成形、射出圧縮成形等が例示されるが、特に限定はない。但し、発泡成形は、上述したように遊技釘を拘束する力が不足するおそれがあるから、好ましくない。
The kind, composition, properties, etc. of the synthetic resin forming the game board are not particularly limited. It may be transparent or opaque.
Examples of the molding method for solidifying the synthetic resin in the mold include injection molding and injection compression molding, but there is no particular limitation. However, foam molding is not preferable because the force for restraining the game nail may be insufficient as described above.

表裏面間に貫通する開口としては、入賞装置、表示装置又は装飾装置を取り付けるための開口、入賞球やアウト球を遊技盤の背面側に誘導するための開口が例示される。また、このような開口だけでなく、遊技盤を弾球遊技機本体に取り付けるための切欠や凹み、賞球用の通路を通すための切欠等も開口と同様に形成できる。   Examples of the opening penetrating between the front and back surfaces include an opening for attaching a winning device, a display device or a decoration device, and an opening for guiding a winning ball or out ball to the back side of the game board. In addition to such openings, notches and recesses for attaching the game board to the main body of the ball and ball game machine, cutouts for passing a path for prize balls, and the like can be formed in the same manner as the openings.

遊技釘を圧入するための下穴は、遊技釘を圧入したときの十分な拘束力が得られるように、また圧入時にひびや割れ等を生じないように、遊技釘の外径に応じて設ける必要がある。一般的には遊技釘の外径をわずかに下回る寸法にするが、具体的な数値は遊技盤を形成する合成樹脂の種類等によって一律にならないので、実験等に基づいて設定すればよい。   A pilot hole for press-fitting the game nail is provided according to the outer diameter of the game nail so that sufficient restraining force can be obtained when the game nail is press-fitted and cracks and cracks are not generated during press-fitting. There is a need. In general, the size is slightly smaller than the outer diameter of the game nail, but specific numerical values are not uniform depending on the type of synthetic resin forming the game board, and may be set based on experiments or the like.

この下穴の入口部分は例えば漏斗状にして、遊技釘を圧入する際の案内面にするとよい。また、入口部分を奥側部分よりも大径にしても(2段穴にしても)、同様の案内効果がある。或いは、下穴の入口部分を漏斗状にした上で、その奥側を2段穴にしてもよい。   The entrance portion of the pilot hole may be formed in a funnel shape, for example, to serve as a guide surface when the game nail is press-fitted. Further, the same guiding effect can be obtained even if the diameter of the entrance portion is made larger than that of the back side portion (a two-step hole). Or after making the entrance part of a pilot hole into a funnel shape, you may make the back | inner side into a two-step hole.

普通、遊技釘は遊技盤の表面に対して垂直とされず、遊技盤の表面を鉛直にしたときに遊技釘が水平よりも約3〜5度程度上向きになるように仰角が与えられている。従って、下穴は、この仰角に対応した角度で設けるのが望ましい。   Normally, the game nail is not perpendicular to the surface of the game board, and the elevation angle is given so that the game nail is about 3 to 5 degrees above the horizontal when the surface of the game board is vertical. . Therefore, it is desirable to provide the pilot hole at an angle corresponding to this elevation angle.

また遊技盤にはガイドレールを固定するためのレールピンも打ち付けられるので、このレールピン用の下穴も遊技釘用と同様にドリル加工で設ければよい。但し、レールピンは遊技盤の表面に対して垂直とされるので、この下穴は遊技盤の表面に対して垂直に設ければよい。   In addition, since a rail pin for fixing the guide rail is also struck on the game board, the pilot hole for the rail pin may be provided by drilling in the same manner as for the game nail. However, since the rail pin is perpendicular to the surface of the game board, the pilot hole may be provided perpendicular to the surface of the game board.

ところで、遊技盤には装飾シート(いわゆるセル)が貼付されるのが一般的である。
透明(少なくとも透光性)の合成樹脂を用いて本発明の遊技盤を製造した場合、セルは貼り付けてもよいし、貼らなくてもよい。また、貼る場合には、裏面に貼ってもよい。
By the way, a decoration sheet (so-called cell) is generally attached to the game board.
When the game board of the present invention is manufactured using a transparent (at least translucent) synthetic resin, the cell may or may not be attached. Moreover, when sticking, you may stick on the back surface.

不透明の合成樹脂を用いて本発明の遊技盤を製造した場合、セルを貼り付けるのが望ましいが、遊技盤の表面に装飾画等を印刷してセルの貼付に代えることもできる。
また、印刷は透明(少なくとも透光性)の合成樹脂を用いて本発明の遊技盤を製造した場合にも適用できる。この場合、遊技盤の表面に印刷してもよいし裏面に印刷してもよい。
When the game board of the present invention is manufactured using an opaque synthetic resin, it is desirable to affix the cell. However, a decorative image or the like can be printed on the surface of the game board to replace the cell.
Printing can also be applied to the case where the game board of the present invention is manufactured using a transparent (at least translucent) synthetic resin. In this case, you may print on the surface of a game board and may print on the back surface.

遊技盤の表面にセルを貼る場合、遊技釘及びレールピンの打ち込み(圧入)は、セルを貼った後に行われるが、周知の通りセルが打ち込み(圧入)を阻害することはない。   When a cell is affixed to the surface of the game board, the game nails and rail pins are driven (press-fitted) after the cell has been affixed, but as is well known, the cell does not impede the drive-in (press-fitting).

請求項1記載の遊技盤の製造方法は、例えば射出成形等の成形方法で表裏面間に貫通する開口を形成するので、入賞装置等を取り付けるための開口や入賞球等を背面側に誘導するための開口を機械加工する必要がなく、それに応じて機械加工の作業量が低下し加工費も低下する。また、このような開口だけでなく、切欠、凹み、溝等も開口と共に形成することで機械加工の作業量及び加工費を更に低減できる。   The game board manufacturing method according to claim 1 forms an opening penetrating between the front and back surfaces by a molding method such as injection molding, for example, so that an opening for attaching a winning device or the like, a winning ball or the like is guided to the back side. Therefore, it is not necessary to machine the opening for machining, and accordingly, the amount of machining work is reduced and the machining cost is also reduced. Moreover, not only such an opening but also a notch, a dent, a groove, and the like are formed together with the opening, so that the amount of machining work and the processing cost can be further reduced.

そして、開口の形成後に遊技釘を圧入するための下穴をドリル加工し、この下穴に遊技釘を圧入するから、圧入された遊技釘を保持する力(拘束力)は十分に強く、遊技球の衝突で遊技釘がぐらついたり、釘調整のためのハンマーに耐えきれずにぐらついたり抜け落ちたりするおそれはない。   And since the pilot hole for press-fitting the game nail is drilled after the opening is formed and the game nail is press-fitted into this pilot hole, the force (restraint force) to hold the press-fitted game nail is sufficiently strong, There is no risk that the game nail will wobble due to the collision of the ball, or that it will not endure the hammer for adjusting the nail and will wobble or fall off.

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]
本実施例の遊技盤1はパチンコ機用であり、図1に示すとおり、一部に切欠があるものの、ほぼ長方形をしている。この遊技盤1には略円弧状のガイドレール2a、2bが取り付けられており、ガイドレール2a、2bによって囲まれた略円形の区画内が遊技領域4とされる。なお、ガイドレール2a、2bの先端間の切れ目部分は返しゴム(図示略)にて閉じられる。
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]
The game board 1 of the present embodiment is for a pachinko machine, and has a substantially rectangular shape as shown in FIG. The game board 1 is provided with substantially arc-shaped guide rails 2a and 2b, and a game area 4 is defined in a substantially circular section surrounded by the guide rails 2a and 2b. In addition, the cut | interruption part between the front-end | tips of the guide rails 2a and 2b is closed with a return rubber (not shown).

遊技領域4の最下部には、遊技領域4を通過してきた遊技球をアウト球として排出するためのアウト穴5が設けられており、ガイドレール2bには遊技球をアウト穴5に誘導するための凹み2cが設けられている。   At the bottom of the game area 4, an out hole 5 is provided for discharging the game ball that has passed through the game area 4 as an out ball, and the guide rail 2 b guides the game ball to the out hole 5. Dent 2c is provided.

そのアウト穴5の上方には、開閉板61によって開閉されるアタッカー式の大入賞口6が配されている。また、大入賞口6の左右斜め上には、それぞれ普通入賞口7、8が配されている。これら大入賞口6及び普通入賞口7、8は共通のベース板9に組み付けられて入賞口ユニット10とされ、ビス11にて遊技盤1に取り付けられている。本実施例では入賞口ユニット10を採用しているが、大入賞口6、普通入賞口7、8をそれぞれ別々に遊技盤1に取り付けることもできる。   Above the out hole 5, an attacker-type big winning opening 6 that is opened and closed by an opening and closing plate 61 is arranged. In addition, the normal winning openings 7 and 8 are arranged obliquely above and to the left and right of the special winning opening 6, respectively. The large winning port 6 and the normal winning ports 7 and 8 are assembled to a common base plate 9 to form a winning port unit 10 and are attached to the game board 1 with screws 11. In this embodiment, the winning opening unit 10 is adopted, but the large winning opening 6 and the normal winning openings 7 and 8 can be separately attached to the game board 1.

大入賞口6の上方には電動チューリップ式の可変入賞装置12と始動入賞口13とを備える複合入賞装置14が設置されている。
図示するところから明らかなように、可変入賞装置12が閉鎖状態(図示の状態)にあるときには、始動入賞口13によって可変入賞装置12への入賞を阻まれる(可変入賞装置12へは、開放時しか入賞できない)。この可変入賞装置12は、その左右に配されている通過口15に遊技球が進入したことに起因する抽選で当たりになると開放される。
Above the grand prize winning port 6, a composite winning device 14 including an electric tulip type variable winning device 12 and a start winning port 13 is installed.
As is apparent from the drawing, when the variable winning device 12 is in the closed state (the illustrated state), the starting winning port 13 prevents the variable winning device 12 from being won (the variable winning device 12 is open when opened). Only winning a prize). The variable prize-winning device 12 is released when a lottery occurs due to the game balls entering the passage openings 15 arranged on the left and right sides thereof.

可変入賞装置12又は始動入賞口13に入賞した場合には大当たり抽選が行われ、これに応じて遊技盤1の背後に配されている表示装置(全体の図示は省略)の画面16にて図柄の変動表示がなされる。なお、表示装置は遊技盤1と一体化されているわけでなく(遊技盤1の一部というわけではない)、画面16を遊技者に対面させる姿勢で遊技盤1の背面部に取り付けられている。   When the variable winning device 12 or the start winning port 13 is won, a big win lottery is performed, and in accordance with this, a picture is displayed on the screen 16 of the display device (the whole illustration is omitted) arranged behind the game board 1. Is displayed. Note that the display device is not integrated with the game board 1 (not part of the game board 1), and is attached to the back of the game board 1 in such a posture that the screen 16 faces the player. Yes.

大当たり抽選が当たりであれば、図柄の変動表示に続いて表示装置(画面16)にて大当たりを示す表示が行われる。その大当たり表示がなされると大当たり遊技の開始となって、大入賞口6が開放される。なお、この表示装置は演出表示用であり、大当たり抽選の結果は図示省略の特別図柄表示装置(例えば7セグメントLED)によって表示されるが、表示装置(画面16)の表示だけでも大当たりか否かを判別可能である。   If the jackpot lottery is a win, the display showing the jackpot is performed on the display device (screen 16) following the symbol change display. When the jackpot display is made, the jackpot game is started and the jackpot 6 is opened. This display device is for effect display, and the result of the big win lottery is displayed by a special symbol display device (not shown) (for example, 7 segment LED), but whether the display device (screen 16) alone is a big hit or not. Can be determined.

遊技盤1には画面16の上辺に対応するようにしてガード庇17が取り付けられている。ガード庇17は、上方からの遊技球が画面16の前方に進入するのを防止するために(遊技球が画面16の前方を通って視認性を阻害するのを防止するために)設置されている。また、画面16の下辺に対応するようにして窓下装飾材18が取り付けられ、窓下装飾材18の左右には風車19が配されている。   A guard rod 17 is attached to the game board 1 so as to correspond to the upper side of the screen 16. The guard rod 17 is installed in order to prevent a game ball from entering the front of the screen 16 (in order to prevent the game ball from impeding visibility through the front of the screen 16). Yes. A window decoration material 18 is attached so as to correspond to the lower side of the screen 16, and windmills 19 are arranged on the left and right sides of the window decoration material 18.

ガード庇17及び窓下装飾材18は、正確にではないが表示装置の画面16の上下限界を、風車19は左右限界を遊技者に示す働きもする。
図示するとおり、遊技領域4には多数の遊技釘20が植設されている。
The guard rod 17 and the decorative material 18 under the window also serve to show the player the upper and lower limits of the screen 16 of the display device, but the windmill 19 shows the left and right limits, though not exactly.
As illustrated, a large number of game nails 20 are implanted in the game area 4.

遊技領域4の中央上部(ガード庇17の上方)にはいわゆる天釘として、普通入賞口7、8、始動入賞口13及び通過口15の直上にはいわゆる命釘として、それぞれ遊技釘20が配置されている。また、左右の風車19及び窓下装飾材18の下方においては、遊技球を複合入賞装置14又は通過口15へと誘導するように、列状の遊技釘20が配置されている。その他、配置密度に差があるものの、適宜に遊技釘20が配されている。   A game nail 20 is arranged as a so-called ceiling nail in the upper center of the game area 4 (above the guard rod 17), and as a so-called life nail just above the normal winning openings 7, 8, the start winning opening 13 and the passing opening 15, respectively. Has been. Further, below the left and right windmills 19 and the under-window decoration material 18, row-like game nails 20 are arranged so as to guide the game balls to the composite winning device 14 or the passage port 15. In addition, although there is a difference in arrangement density, the game nails 20 are appropriately arranged.

遊技盤1の本体は透明な合成樹脂(本実施例ではポリカーボネート)の平板であり、例えば射出圧縮成形によって図2に示す形状に製造されている。遊技盤1の本体の板厚は、アウト穴5を通った遊技球を落下させるための溝や位置決め用のダボ穴等(図示は省略)を除いては、全体に均一(本実施例では19mm)である。   The main body of the game board 1 is a flat plate made of a transparent synthetic resin (polycarbonate in this embodiment), and is manufactured in the shape shown in FIG. 2 by, for example, injection compression molding. The thickness of the main body of the game board 1 is uniform (19 mm in the present embodiment) except for a groove for dropping the game ball that has passed through the out hole 5 and a dowel hole for positioning (not shown). ).

図2に示すように、遊技盤1には、入賞口ユニット10、複合入賞装置14及び通過口15を取り付けるための取付穴6a、7a、14a、15aやアウト穴5が貫通して設けられている。   As shown in FIG. 2, the game board 1 is provided with mounting holes 6 a, 7 a, 14 a, 15 a and an out hole 5 for attaching the winning port unit 10, the composite winning device 14 and the passing port 15. Yes.

図3に示すように、遊技盤1には上述の遊技釘20が打ち込まれ、またガイドレール2a、2bを固定するためのレールピン21が打ち込まれている。なお、図3では、遊技盤1と遊技釘20、レール2a、2b及びレールピン21の関係を簡明に説明するために、遊技釘20及びレールピン21は各1本だけを図示してある。   As shown in FIG. 3, the above-mentioned game nail 20 is driven into the game board 1, and rail pins 21 for fixing the guide rails 2a and 2b are driven therein. In FIG. 3, only one game nail 20 and one rail pin 21 are shown in order to simplify the relationship between the game board 1 and the game nail 20, the rails 2 a and 2 b and the rail pin 21.

遊技釘20は、遊技盤1に設けられた下穴25に打ち込まれているが、下穴25は遊技盤1の成形後にドリル加工にて設けられたものである。風車19の軸釘及びレールピン21も同様に成形後のドリル加工で設けられた下穴に打ち込まれている。   The game nail 20 is driven into a prepared hole 25 provided in the game board 1, and the prepared hole 25 is provided by drilling after the game board 1 is formed. Similarly, the shaft nail of the windmill 19 and the rail pin 21 are also driven into a prepared hole provided by drilling after molding.

図4に示すように、下穴25は、遊技盤1の表面に開口する案内穴25aと、案内穴25aの奥側に連続して形成された圧入穴25bとから構成されている。図示するとおり案内穴25aの方が圧入穴25bよりも大径で、下穴25は2段穴になっている。詳しくは案内穴25aの内径は遊技釘20の軸部分の直径をわずかに上回り、圧入穴25bの内径は遊技釘20の軸部分の直径をわずかに下回る。従って、遊技釘20は圧入穴25bに嵌着しており、遊技釘20は圧入穴25bに確実に拘束されている。   As shown in FIG. 4, the pilot hole 25 includes a guide hole 25 a that opens on the surface of the game board 1, and a press-fit hole 25 b that is continuously formed on the back side of the guide hole 25 a. As shown in the figure, the guide hole 25a has a larger diameter than the press-fit hole 25b, and the prepared hole 25 is a two-stage hole. Specifically, the inner diameter of the guide hole 25a is slightly larger than the diameter of the shaft portion of the game nail 20, and the inner diameter of the press-fitting hole 25b is slightly smaller than the diameter of the shaft portion of the game nail 20. Therefore, the game nail 20 is fitted in the press-fitting hole 25b, and the game nail 20 is reliably restrained by the press-fitting hole 25b.

この下穴25への遊技釘20の打ち込みは、周知の自動釘打ち機を用いて行われるが、その際に案内穴25aが遊技釘20の先端を案内するので、この打ち込みが円滑かつ正確になる。   The game nail 20 is driven into the pilot hole 25 using a known automatic nailing machine. At this time, the guide hole 25a guides the tip of the game nail 20, so that the driving is smoothly and accurately performed. Become.

また、案内穴25aの内径が遊技釘20の軸の直径をわずかに上回るために、打ち込まれた遊技釘20と案内穴25aの内面との間にはわずかな隙間ができる。
一般に遊技球は、遊技盤1の表面に接触して、或いは遊技盤1の表面からわずかに離れた位置を流下してくるので、遊技釘20の遊技盤1の表面に近い部分に衝突することになる。そのときに遊技釘20の根本と遊技盤1との間に上述の案内穴25aによる隙間があると、遊技釘20の根本と遊技盤1との間に隙間が無い(密着している)ときよりも、遊技釘20が柔軟に弾性変形する。
Further, since the inner diameter of the guide hole 25a is slightly larger than the diameter of the shaft of the game nail 20, there is a slight gap between the game nail 20 that has been driven and the inner surface of the guide hole 25a.
In general, the game ball comes into contact with the surface of the game board 1 or flows down a position slightly away from the surface of the game board 1, so that it collides with a portion of the game nail 20 close to the surface of the game board 1. become. At this time, if there is a gap between the root of the game nail 20 and the game board 1 due to the above-described guide hole 25a, there is no gap between the root of the game nail 20 and the game board 1 (in close contact). Instead, the game nail 20 is elastically deformed flexibly.

従来の合板製の遊技盤であれば、木材であるから遊技釘20の根本部分が強固に拘束されるわけではないから、遊技釘20の根本と遊技盤1との間に隙間が無くても(密着していても)、遊技釘20の根本部分(遊技盤の内部にある部分)も若干の弾性変形が可能になっている。つまり、遊技釘20を棒状のばねと見た場合、その固定支点は遊技盤の表面ではなくて、わずかではあるが遊技盤の内部に位置していると言える。   Since a conventional plywood game board is made of wood, the base portion of the game nail 20 is not firmly restrained, so even if there is no gap between the base of the game nail 20 and the game board 1. Even if it is in close contact, the base portion of the game nail 20 (the portion inside the game board) can be slightly elastically deformed. That is, when the game nail 20 is viewed as a rod-shaped spring, it can be said that the fixed fulcrum is not located on the surface of the game board but is located slightly inside the game board.

つまり、下穴25を案内穴25aと圧入穴25bとの2段穴にして遊技釘20と案内穴25aの内面との間に隙間を確保することにより、遊技球が衝突したときの遊技釘20の挙動(弾性変形、これに伴う弾発等)を、従来の合板製の遊技盤に打ち込まれた遊技釘と類似のものにできる。   In other words, the lower hole 25 is a two-stage hole of the guide hole 25a and the press-fitting hole 25b, and a gap is secured between the game nail 20 and the inner surface of the guide hole 25a. The behavior (elastic deformation, the associated impact, etc.) can be made similar to a conventional game nail driven into a game board made of plywood.

また、遊技釘20の根本と遊技盤1との間に上述のような隙間を設けることにより、遊技球が遊技釘20衝突したときの衝撃が案内穴25aの開口縁に及ぼされないから、そのような衝撃で案内穴25aの開口縁がひび割れるのを防止できる。同様に、いわゆる釘調整のためにハンマで遊技釘20を叩いたときに案内穴25aの開口縁がひび割れるのを防止できる。   Further, by providing the gap as described above between the base of the game nail 20 and the game board 1, the impact when the game ball collides with the game nail 20 is not exerted on the opening edge of the guide hole 25a. It is possible to prevent the opening edge of the guide hole 25a from cracking due to a strong impact. Similarly, the opening edge of the guide hole 25a can be prevented from cracking when the game nail 20 is hit with a hammer for so-called nail adjustment.

なお、下穴25の軸は遊技盤1の表面に対して垂直ではなく、上向きに約4度の角度がつけられている。このため、遊技釘20は、これに対応する約4度の仰角αが与えられている。   Note that the axis of the pilot hole 25 is not perpendicular to the surface of the game board 1 but is inclined upward by about 4 degrees. For this reason, the game nail 20 is given an elevation angle α of about 4 degrees corresponding thereto.

一方、詳細の図示は省略するが、レールピン21(その下穴)は遊技盤1の表面に対して垂直になっている。また、風車19の軸釘は遊技釘20と同様の仰角αが与えられている。   On the other hand, although illustration of details is omitted, the rail pin 21 (its pilot hole) is perpendicular to the surface of the game board 1. Further, the shaft nail of the windmill 19 is given an elevation angle α similar to that of the game nail 20.

この遊技盤1は、合成樹脂製で少なくとも遊技釘20が配設される範囲は板厚が均等な遊技盤1であり、金型内で合成樹脂を固化させる成形により表裏面間に貫通する開口(取付穴6a、7a、14a、15a、アウト穴5)及びアウト穴5を通った遊技球を落下させるための溝や位置決め用のダボ穴等を形成し、その後に遊技釘20を圧入するための下穴25をドリル加工する手順で製造されるので、取付穴6a、7a、14a、15a、アウト穴5等を機械加工する必要がなく、それに応じて機械加工の作業量が低下し加工費も低下する。また、このような開口だけでなく、切欠、凹み、溝等も開口と共に形成することで機械加工の作業量及び加工費を更に低減できる。   This game board 1 is made of synthetic resin, and at least the game nails 20 are disposed in the game board 1 having a uniform plate thickness, and an opening that penetrates between the front and back surfaces by molding the synthetic resin in the mold. (Mounting holes 6a, 7a, 14a, 15a, out hole 5) and a groove for dropping the game ball passing through the out hole 5, a dowel hole for positioning, etc. are formed, and then the game nail 20 is press-fitted Since the pilot hole 25 is manufactured by the drilling procedure, it is not necessary to machine the mounting holes 6a, 7a, 14a, 15a, the out hole 5, etc., and the amount of machining work is reduced accordingly, and the machining cost is reduced. Also decreases. Moreover, not only such an opening but also a notch, a dent, a groove, and the like are formed together with the opening, so that the amount of machining work and the processing cost can be further reduced.

そして、取付穴6a、7a、14a、15a、アウト穴5等の形成後に遊技釘20を圧入するための下穴25をドリル加工し、この下穴25に遊技釘を圧入するから、圧入された遊技釘20を保持する力(拘束力)は十分に強く、遊技球の衝突で遊技釘20がぐらついたり、釘調整のためのハンマーに耐えきれずにぐらついたり抜け落ちたりするおそれはない。   Then, after forming the mounting holes 6a, 7a, 14a, 15a, the out hole 5, etc., the pilot hole 25 for press-fitting the game nail 20 is drilled, and the game nail is press-fitted into the pilot hole 25. The force (restraint force) for holding the game nail 20 is sufficiently strong, and there is no possibility that the game nail 20 will wobble due to the collision of the game ball, or will not endure the hammer for adjusting the nail and will wobble or fall off.

またガイドレール2a、2bを固定するためのレールピン21及び風車19の軸釘についても、同様に下穴をドリル加工して打ち付けられるので、遊技釘20と同様に、遊技球の衝突でぐらつく等のおそれはない。
[その他]
下穴25の入口部分を、図5に例示するように面取りして漏斗状の案内面25cにしても、遊技釘20の根本部分の周囲に隙間ができるので、上述したと同様の効果が得られる。この場合、図5(a)のように案内面25c、案内穴25a、圧入穴25bを備える構成にしてもよいし、図5(b)のように案内面25cと圧入穴25bとの構成にしてもよい。
In addition, the rail pin 21 for fixing the guide rails 2a and 2b and the shaft nail of the windmill 19 can also be driven by drilling a pilot hole in the same manner. There is no fear.
[Others]
Even if the entrance portion of the pilot hole 25 is chamfered as illustrated in FIG. 5 to form a funnel-shaped guide surface 25c, a gap is formed around the base portion of the game nail 20, so that the same effect as described above can be obtained. It is done. In this case, the guide surface 25c, the guide hole 25a, and the press-fit hole 25b may be configured as shown in FIG. 5A, or the guide surface 25c and the press-fit hole 25b may be configured as shown in FIG. 5B. May be.

何れの場合も(実施例でも)、遊技釘20の根本部分の周囲に形成される隙間の深さ(遊技釘20の軸方向の寸法)は1mm以上が望ましい。その上限は限定されないが、これを深くしてもそれに見合って効果が向上するわけではなく、また遊技盤1の板厚との関係で圧入穴25bの長さが制限されるから、自ずと限度はあり、通常は5mm以下、好ましくは3mm以下である。   In any case (even in the embodiment), the depth of the gap formed in the periphery of the base portion of the game nail 20 (the dimension in the axial direction of the game nail 20) is preferably 1 mm or more. The upper limit is not limited, but even if it is deepened, the effect is not improved correspondingly, and the length of the press-fitting hole 25b is limited in relation to the thickness of the game board 1, so the limit is naturally Yes, usually 5 mm or less, preferably 3 mm or less.

実施例の場合は透明(透光性)の合成樹脂を用いて遊技盤1を製造したので、装飾シート(いわゆるセル)についての説明を省略したが、従来と同様にセルを貼り付けてもよい。その場合、裏面に貼ってもよい。また、セルに代えて遊技盤1の表面又は裏面に印刷を施してもよい。   In the case of the embodiment, since the game board 1 is manufactured using a transparent (translucent) synthetic resin, the description of the decorative sheet (so-called cell) is omitted, but the cell may be pasted as in the conventional case. . In that case, you may affix on a back surface. Moreover, it may replace with a cell and may print on the surface or the back surface of the game board 1.

また、実施例の遊技盤1は透明(透光性)であるので、画面16を臨ませるための窓は設けていないが、図6に例示するように窓22を設けて、これに画面16を臨ませることもできる。   Further, since the game board 1 of the embodiment is transparent (translucent), no window for facing the screen 16 is provided, but a window 22 is provided as illustrated in FIG. Can also be exposed.

不透明の合成樹脂を用いて本発明の遊技盤を製造した場合、表示装置のための窓が必要になる。また、セルを貼り付けるのが望ましい。   When the game board of the present invention is manufactured using an opaque synthetic resin, a window for a display device is required. Moreover, it is desirable to paste a cell.
