【発明の属する技術分野】
本発明は、遊戯機における釘間隔測定装置と釘間隔測定方法に係り、特にパチンコ遊戯機や雀球遊戯機とかスマートボール遊戯台などにおけるセル板に植設した複数の障害釘の間隔測定装置と釘間隔測定方法に関する。
【０００２】
【従来の技術】
パチンコ遊戯機における釘間隔確認作業は、出玉率に直接係わる極く精密かつ、面倒でも重要な作業であるため、従来では遊戯機のセル板面に植設した二本の障害釘の内法間隔をほぼピストル状の釘間隔測定具を用いて実行している。
その従来例としては、特許第３０１０５４３号公報、特許第３０８４５６０号公報および特開平１０−４３３７４号公報記載のものがそれぞれ周知である。
これらの各従来例は、遊戯機における二本の障害釘の内法間隔を測定するに当たり、ほぼピストル状の釘間隔測定具の先端に突設した二本一対の回動アームを前記釘間隔測定具に設けたトリガ部材の操作により閉じた状態で前記各障害釘の対向周面の間に挿入した後、前記トリガ操作の解除により前記各アームを開いて各アームの先端を各障害釘の対向周面に弾接させることで、前記二本の障害釘の内法間隔を測定できるとした釘間隔測定装置である。
【０００３】
【発明が解決しようとする課題】
これら従来例における肝心の回動アームの変位量に対応して前記ロータリーエンコーダを回動変位させる点について吟味すると、前記各従来例公報中、唯一の具体的な記載例によれば、回動アームの変位を先ず、この回動アームのラック部分に噛合した平ギヤの回転変位量に機械的に変換し、この平ギヤの回転力でこれに結合したロータリーエンコーダを機械的に回動させることで、上記平ギヤの回転変位量を電気信号変化量に変換し、この変化信号の演算処理信号で前記二本の障害釘の内法間隔を測定できるとした釘間隔測定装置であるので、肝心の回動アームの動きを阻害する無用な機械的負荷が多く存在している。
【０００４】
すなわち、これら各従来例では、回動アームの変位を先ず、この回動アームのラック部分に噛合した平ギヤの回転変位量に機械的に変換し、この平ギヤの回転力でこれに結合したロータリーエンコーダを機械的に回動させるものであるから、上記回動アームの動きを機械的に阻害する要素が多く存在するため、釘間隔測定結果に大きな間違いが生じる危険が有るし、回動ラックに噛合した平ギヤは、その噛合部分にバックラッシュと称する噛合間隙や噛合ムラなどによる機械的な誤差が生じるだけでなく、前記ロータリーエンコーダ自体にもその機械−電気変換部分におけるメカ的誤差および電気的な誤差も生じるため、これら各従来例は、メカ的にも電気的にも不安定要素が多く存在し、肝心の釘間隔測定結果に大きな誤差が生じ易いという本質的な問題点が有るほかに、機械的に構成複雑かつ、部品点数も多く要するため、部品管理・組立製造・販売・購入・使用のすべての面で扱い辛く不便で面倒であるという本質的かつ、大きな問題点が有る。
【０００５】
また、偏平箱状の釘間隔測定具内の対物レンズとＣＣＤ撮像素子とを用いて二本の障害釘の間隔を測定表示できるとしている特開２００１−２１２２９４号公報も有るが、この公報には釘間隔測定用回動アームにおける測定マーカを上記ＣＣＤ撮像素子でビデオカメラ式に撮像する過程の記載が有るだけで、撮像済映像から実際にどのようにして釘間隔測定結果を表示できるのかという肝心な電気的プロセスの記載が何もなく、単なる願望事項の記載に止まり、全体的に漠としていて著しく不明な点が多い本質問題が有る公開公報であって、これで果して二本の障害釘の内法間隔を測定表示できるかどうか極めて疑わしい従来例である。
【０００６】
この発明は、上記従来例公報記載の多くの問題点をすべて除去するために、遊戯機における障害釘の周面に接離させる釘間隔測定用の平行開閉アームの動きを阻害する無用な機械的負荷を無くし、肝心の釘間隔を精確かつ、容易に測定表示可能とすることを目的とする。
【０００７】
【課題を解決するための手段】
上記した本発明の目的は、遊戯機における二本の障害釘の内法間隔をほぼピストル状の釘間隔測定具により測定する釘間隔測定装置を構成するに当たり、前記釘間隔測定具の先端に前記各障害釘に接離させる固定アームと平行開閉アームとを対向突設し、平行開閉アームの先端を固定アームの先端と共に各障害釘の対向周面に弾接させることで、平行開閉アームに配設した可動光源からのビーム光を無接触で受けるチャージ・カップル・デバイス（ＣＣＤ）などを用いた光源位置センサから前記弾接ポイントに対応した釘間隔データ信号を検出し、この信号を演算処理して釘間隔計数信号に変換後、現字表示体を駆動制御することで、各障害釘の内法間隔を前記表示体で数値表示可能となしたことで達成できた。
なお、前記各アームの先端には、外向き突面を形成してもよく、また、現字表示体の表示面を釘間隔測定具の外面に配置して前記内法間隔を釘間隔測定具自体で数値表示可能とすることもでき、さらに前記釘間隔測定具をカバー部材で現字表示体の表示面および前記各アームおよびトリガ部材を除いて隠蔽してもよく、さらにまた、前記平行開閉アームにプーリを設け、このプーリを前記カム部材に転接させ、平行開閉アームをトリガ部材の操作で変位可能となしてもよい。
【０００８】
【発明の実施の形態】
本発明の実施の形態のうち、先ず、本発明の基本的な形態例を説明する。

【００１０】
ただし、上記図１０（ａ）における符号Ｐ１は、平行開閉アーム５の全閉ポイントであり、また符号Ｐ２は全開ポイントである。さらに符号Ｔは、前記トリガ部材９の解除操作開始直後にトリガスイッチＳにより、微分回路等周知手段で発生させるようにしたトリガパルスであり、このパルスＴを始点として前記釘間隔データ信号Ｓ１を発生させるのであるが、その持続時間幅は前記内法間隔Ｄの範囲内で前記弾接ポイントに対応して前記のように変化するようにし、このデータ信号Ｓ１に対応して前記釘間隔計数信号Ｓ２のパルス数が変化するように光源位置センサＰや演算処理回路をそれぞれ周知のプログラム制御手段で構成する。
なお、図２における符号ＳＷで示す部分は手動電源スイッチ、また各図における符号Ｎで示すものは、前記各部材を図３の固定ねじｎで所定の配置に組立てる固定部材であり、符号９Ｂで示す部分はトリガ部材９の枢支部９Ｃを前記枢軸９Ａで枢支する枢支孔、さらに符号９Ｄで示すものはトリガ部材９の復帰用蔓巻きばねであり、また図９における符号１３で示すものは、前述したトリガ引き操作で可動光源Ｌと共に矢示方向に動く小孔１３Ａ付きの外光遮断板である。
前記各機構部材は、金属等の強靱材で精度よく作り、また前記釘間隔測定具３を図３のようなプラスチックカバー部材１１で現字表示体Ａの表示面および前記各アーム４・５およびトリガ部材９を除いて図２のように隠蔽してもよい。
【００１１】
本発明の構成は以上のようなもので、以下その動作例につき説明する。
遊戯機における前記二本の障害釘２の内法間隔Ｄを測定するには、前記平行開閉アーム５を前記トリガ部材９の引き操作により図５のように閉じた状態で、前記各アーム４・５の各外向き突面４Ａ・５Ａをそれぞれ前記各障害釘２の対向周面２Ａの間に挿入した後、前記トリガ操作を解除することで、前記平行開閉アーム５を前記ばね部材７の弾力で開いてこの平行開閉アーム５の外向き突面５Ａを固定アーム４の外向き突面４Ａと共に各障害釘２の対向周面２Ａに図１・図８のように弾接させることで、前述したように光源位置センサＰから上記弾接ポイントに対応して前記内法間隔Ｄの範囲内で信号持続時間幅が変化する図１０（ａ）のような釘間隔データ信号Ｓ１を得ることができ、このデータ信号Ｓ１を前述したように演算処理して図１０（ｂ）のような釘間隔計数信号Ｓ２に変換後、この計数信号Ｓ２で現字表示体Ａを前述のように駆動制御することで、二本の障害釘２の内法間隔Ｄを前記表示体Ａで図２のように数値表示することができた。
【００１２】
【実施例】
前記可動光源Ｌは、トリガ部材９のトリガ操作で開閉するスイッチ（周知のものでよいから図示せず）で点滅させるようにしてもよく、前記カバー部材１１内には電源電池を内装してもよく、また前記各アームの外向き突面４Ａ・５Ａは省略してもよいが、このときには各アームを斜めに各障害釘２に宛がい各アームの外側自体が釘の大径頭部に当接しないようにして前記各アームの先端外面自体で前記と同様に釘間隔を測定することもでき、さらに現字表示体Ａは、釘間隔測定具３の外部にリード線を介して別に配置してもよいが、現字表示体Ａの表示面を前記のように釘間隔測定具３の外面に配置すれば、前記各障害釘２の内法間隔Ｄを釘間隔測定具３自体の外面で数値表示可能とすることもでき、また前記平行開閉アーム５に回転プーリ１２を設け、このプーリ１２を前記カム部材１０に転接させ、平行開閉アーム５をトリガ部材９の操作で変位可能となしてもよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a nail spacing measuring device and a nail spacing measuring method in a game machine, and more particularly to a spacing measuring device for a plurality of obstacle nails implanted in a cell board in a pachinko game machine, a sparrow ball game machine, a smart ball game table or the like. The present invention relates to a method for measuring nail spacing.
[0002]
[Prior art]
Since checking the spacing between nails in a pachinko amusement machine is extremely precise and directly involved in the payout rate, it is an important work even if it is troublesome. The spacing was implemented using a pistol-like nail spacing measurement tool.
As the conventional examples, those described in Japanese Patent No. 3010543, Japanese Patent No. 3084560 and Japanese Patent Application Laid-Open No. 10-43374 are well known.
In each of these conventional examples, when measuring the inner clearance between two obstacle nails in a game machine, a pair of two rotating arms protruding from the tip of a substantially pistol-shaped nail clearance measuring tool are used to measure the nail clearance. After being inserted by the operation of the trigger member provided on the tool and inserted between the opposing peripheral surfaces of the obstacle nails, the arms are opened by releasing the trigger operation, and the distal end of each arm faces the obstacle nail. This is a nail interval measuring device that can measure the inner clearance between the two obstacle nails by elastically contacting the peripheral surface.
[0003]
[Problems to be solved by the invention]
Examining the fact that the rotary encoder is rotationally displaced in accordance with the amount of displacement of the pivotal arm of the prior art, according to the only specific description example in each of the prior art publications, Is mechanically converted into a rotational displacement of a spur gear meshed with the rack portion of the rotating arm, and a rotary encoder coupled to the spur gear is mechanically rotated by the rotational force of the spur gear. The nail displacement measuring device converts the rotational displacement of the spur gear into an electrical signal variation, and can measure the inner clearance between the two obstacle nails by an arithmetic processing signal of the variation signal. There are many unnecessary mechanical loads that hinder the movement of the rotating arm.
[0004]
That is, in each of these conventional examples, the displacement of the rotating arm was first mechanically converted into the rotational displacement of the spur gear meshed with the rack portion of the rotating arm, and the rotational force was coupled to the spur gear by the rotational force of the spur gear. Since the rotary encoder is mechanically rotated, there are many elements that mechanically hinder the movement of the rotary arm, and there is a risk that a large error may occur in the nail spacing measurement result. In the spur gear meshing with the gears, not only mechanical errors due to meshing gaps and meshing irregularities called backlash occur in the meshing portion, but also the mechanical error and the electrical error in the mechanical-electrical conversion portion of the rotary encoder itself. In each of these conventional examples, there are many mechanically and electrically unstable elements, and a large error is likely to occur in the essential nail spacing measurement result. In addition to the inherent problems, the mechanical structure is complicated and the number of parts is large, so it is difficult, inconvenient, and cumbersome to handle in all aspects of parts management, assembly, manufacturing, sales, purchase, and use. And there is a big problem.
[0005]
Japanese Patent Application Laid-Open No. 2001-212294 discloses that the distance between two obstacle nails can be measured and displayed using an objective lens and a CCD image pickup device in a flat box-shaped nail distance measuring instrument. The only point is that there is a description of the process of imaging the measurement marker in the rotating arm for nail spacing measurement with the above-mentioned CCD image sensor using a video camera method, and it is important how the nail spacing measurement result can be actually displayed from the captured video. There is no description of any electrical process, it is only a description of desired items, and there is an essential problem that is generally vague and has many unclear points. This is a conventional example in which it is extremely doubtful whether the internal law interval can be measured and displayed.
[0006]
In order to eliminate all of the many problems described in the above publications of the related art, the present invention provides an unnecessary mechanical mechanism that hinders the movement of a parallel opening / closing arm for measuring a gap between nails that is brought into contact with and separated from the peripheral surface of an obstacle nail in a game machine. It is an object of the present invention to eliminate the load and accurately and easily measure and display the essential nail interval.
[0007]
[Means for Solving the Problems]
An object of the present invention described above is to configure a nail spacing measuring device for measuring an inner clearance between two obstacle nails in a game machine with a substantially pistol-shaped nail spacing measuring device, wherein the tip of the nail spacing measuring device is A fixed arm and a parallel opening / closing arm which come into contact with / separate from each obstacle nail are provided so as to face each other. A light source position sensor using a charge-coupled device (CCD) or the like that receives a light beam from a movable light source in a non-contact manner detects a nail interval data signal corresponding to the elastic contact point, and processes this signal. This was achieved by controlling the current character display body after converting it into a nail spacing count signal, thereby enabling the numerical display of the inner clearance of each obstacle nail on the display body.
Note that an outwardly projecting surface may be formed at the tip of each of the arms, and the display surface of the current character display is arranged on the outer surface of the nail spacing measuring tool so that the inner space is set to the nail spacing measuring tool. It is also possible to display a numerical value by itself, and the nail gap measuring tool may be concealed by a cover member except for the display surface of the current character display body and each of the arms and the trigger member. A pulley may be provided on the arm, and the pulley may be brought into contact with the cam member so that the parallel opening / closing arm can be displaced by operating the trigger member.

Reference numeral T denotes a trigger pulse which is generated by a trigger switch S by a well-known means such as a differentiating circuit by the trigger switch S immediately after the trigger member 9 is released, and the pulse T is used as a starting point to generate the nail interval data signal S1. However, the duration is varied within the range of the inner clearance D in accordance with the point of impact as described above, and in correspondence with the data signal S1, the nail interval counting signal S2 is changed.
