Description

【０００１】
【発明の属する技術分野】
本発明はパチンコ機において球を発射するために人為操作されるハンドルグリップと呼ばれるような球発射操作装置に関する。
【０００２】
【従来の技術】
特開平６−２７７３３７号公報で開示された球発射操作装置は遊技者が球発射操作装置に触れていることを検出するためのタッチスイッチ回路基板が遊技者で回転操作される回転操作体の前面に取り付けられている。
【０００３】
図４は前者と異なる従来の球発射操作装置を分解して示す。図４において、１は球発射操作装置の土台である合成樹脂からなるグリップ本体であって、筒状の胴体部２、胴体部２の前面に胴体部２よりも大きな円形に形成された皿部３、皿部３の中心から前側に突出した筒状の軸受部４、軸受部４の周囲に位置するように皿部３から前側に突出した複数の支柱５、支柱５と異なる位置で軸受部４の周囲に位置するように皿部３から前側に突出したばね止部６を備える。８は球発射操作装置の操作量を抵抗値の変化に変換して出力する可変抵抗器であって、可変抵抗器８が胴体部２の裏側から胴体部２の内部に挿入され、可変抵抗器８の前側に設けられた取付部９が皿部３に形成された図外の取付孔を経由して皿部３よりも前側に突出し、皿部３よりも前側に突出した取付部９に形成された図外の雄ねじ部にナット１０が締結されることによって、可変抵抗器８がグリップ本体１に固定される。取付部９の中心部には可変抵抗器８における抵抗値を変えるための抵抗器軸１１が取付部９よりも前側に回転可能に突出する。
【０００４】
１３は遊技者で回転操作されるハンドルレバーと呼ばれる合成樹脂からなる回転操作体であって、円板１４、円板１４の中心から前側に突出した筒部１５、筒部１５の周壁に形成された溝１６、筒部１５の周囲に位置するように円板１４に形成された一対の取付孔１７（一対の取付孔１７のうちの１個は筒部１５で隠れているので図示していない）、取付孔１７と異なる位置で筒部１５の周囲に位置するように円板１４に形成されたばね受部１８、取付孔１７やばね受部１８よりも外側で円板１４の周囲に筒部１５を中心とする１つの円周上に形成された逃孔１９、逃孔１９よりも外側で円板１４の周囲から前側に突出したフランジ２０、フランジ２０よりも外側で円板１４の周囲から後側に突出したリム２１、リム２１から円板１４の径方向外側に突出した指掛部２２を備える。２５は合成樹脂からなる半球形のカバーであって、内側に複数の支柱２６を備える。２８は合成樹脂からなる駆動歯車であって、大径筒部２９、大径筒部２９の外周面に形成された歯車３０、歯車３０と干渉しないように大径筒部２９の外周面から前側に突出した一対の脚部３１、大径筒部２９から後側に同軸状に大径筒部２９よりも小径な筒状に突出した軸部３２を備える。３３は従動歯車であって、グリップ本体１に固定的に取り付けられた可変抵抗器８の抵抗器軸１１に一緒に回転するように嵌め込まれる。３５は回転操作体１３に復元力を与えるばねである。３６は被覆電線である。
【０００５】
球発射操作装置は次のように組み立てられる。従動歯車３３が抵抗器軸１１に嵌め込まれ、図外の止ねじが回転操作体１３の前側から取付孔１７を経由して脚部３１に締結されることで駆動歯車２８が回転操作体１３の裏面に固定され、被覆電線３６における導体の一端が回転操作体１３の表面を被覆した図外の金属メッキに止ねじ３７で接続され、被覆電線３６の他端が回転操作体１３の前側から溝１６および筒部１５の内部を経由して回転操作体１３の裏側に引き出される。回転操作体１３の裏側に引き出された被覆電線３６が駆動歯車２８の前側から大径筒部２９の内部や軸部３２の内部を経由して駆動歯車２８の裏側に引き出される。回転操作体１３の裏側に引き出された被覆電線３６はグリップ本体１の前側から軸受部４の内部および胴体部２の内部を経由してグリップ本体１の裏側に引き出される。グリップ本体１の裏側に引き出された被覆電線３６における導体の他端は球発射操作装置が取り付けられる図外の遊技機枠に装着されたタッチセンサの入力部に接続される。
【０００６】
そして、グリップ本体１の支柱５やばね止部６が回転操作体１３の裏側から逃孔１９に挿入され、駆動歯車２８の軸部３２がグリップ本体１の軸受部４に回転可能に嵌め込まれる過程において、駆動歯車２８と従動歯車３３とが互いに噛み合わされる。その後、ばね３５の中央部に形成されたコイルスプリング部が回転操作体１３の筒部１５に非接触に外嵌装着され、ばね３５の一端部がばね受部１８に係留され、ばね３５の他端部がばね止部６に止ねじ３８で固定される。さらに、カバー２５が回転操作体１３の前側に被せられ、回転操作体１３よりも前側に突出したグリップ本体１の支柱５とカバー２５の支柱２６とがグリップ本体１の裏側から止ねじ３９で個別に固定される。これによって、回転操作体１３がグリップ本体１とカバー２５との間に回転可能に挟み込まれ、指掛部２２がグリップ本体１およびカバー２５よりも外側に配置された形態となる。
【０００７】
【発明が解決しようとする課題】
しかしながら、特開平６−２７７３３７号公報の球発射操作装置はタッチスイッチ回路基板からの信号を遊技機枠に設けられた制御装置に出力する被覆電線が回転操作体の前側から回転操作体の周囲に形成された逃孔を経由して回転操作体の裏側に引き出される構造であるため、回転操作体が球を発射しようとする遊技者で回転操作されるたびに、被覆電線が回転操作体の回転に伴い連れ動いて回転操作体の動きを邪魔するばかりでなく断線する可能性も高い。また、図４の球発射操作装置は回転操作体１３を回転可能に支持する機構が回転操作体１３から後側に突出した軸部３２とグリップ本体１の軸受部４との嵌め合いで形成された片側支持構造であるため、回転操作体１３の回転が円滑でないうえ、回転操作体１３ががたつきやすいという問題点があった。
【０００８】
そこで、本発明は回転操作体の両側支持構造によって、被覆電線の保護、回転操作体のがたつき防止、回転操作体の回転円滑化を図り、品質信頼性の高いパチンコ機の球発射操作装置を提供するものである。
【０００９】
【課題を解決するための手段】
本発明にあっては、グリップ本体とカバーとが互いに同軸状に向き合って結合されることで、回転操作体が回転操作体の前側に位置されるカバーと回転操作体の裏側に位置されるグリップ本体との間で挟まれた格好で回転可能に支持されたパチンコ機の球発射操作装置において、回転操作体に回転操作体の回転中心と同軸に取り付けられて回転操作体の前側に突出してカバーと嵌め合わされたことでカバーに対して回転可能な前側軸部と、回転操作体に回転操作体の回転中心と同軸に取り付けられて回転操作体の裏側に突出してグリップ本体と嵌め合わされたことでグリップ本体に対して回転可能な筒状の裏側軸部と、回転操作体の前面に取り付けられたタッチセンサとを備え、タッチセンサから回転操作体に形成された逃孔を介して回転操作体の裏側に引き出された被覆電線が、裏側軸部の外側から裏側軸部の内部を経由してグリップ本体の裏側に引き出されたことによって、回転操作体が球を発射しようとする遊技者で回転操作されても、タッチセンサの被覆電線が回転操作体の回転に伴い旋回することはなく、当該被覆電線が回転操作体の動きを邪魔することもなく、遊技者が回転操作体を円滑に回転操作することができる。しかも、タッチセンサの被覆電線が回転操作体の回転に伴い旋回することがないので、当該被覆電線が断線することも防止することができる。また、回転操作体がグリップ本体とカバーとに対し軸部と軸受部との嵌め合いで両側支持構造に支持されることによって、遊技者が回転操作体を円滑に回転操作することができるうえ、回転操作体ががたつくことはなく、回転操作体がグリップ本体とカバーとの間に回転可能に安定に支持される。また、グリップ本体に固定された可変抵抗器よりグリップ本体の前側に突出する抵抗器軸に設けられた従動歯車と、従動歯車と噛み合う駆動歯車とを備え、駆動歯車が大径筒部と上記裏側軸部とを備え、回転操作体の前側に突出する前側軸部を裏側から大径筒部の一端で押さえ付けるように大径筒部の一端と回転操作体の裏面とが互いに結合されるとともに、大径筒部の一端と回転操作体の裏面との間に凹部が形成され、タッチセンサから回転操作体に形成された逃孔を介して回転操作体の裏側に引き出された被覆電線が、駆動歯車の外側から凹部及び駆動歯車の内部を経由してグリップ本体の裏側に引き出されたことも特徴とする。
【００１０】
【発明の実施の形態】
図１から図３は一実施形態であって、図１はパチンコ機の球発射操作装置の外観を分解して示し、図２は回転操作体１３周りを分解して裏側から示し、図３は組み立てられた球発射操作装置の断面を示す。
【００１１】
図１を参照し、パチンコ機の球発射操作装置について説明する。球発射操作装置はグリップ本体１、可変抵抗器８、回転操作体１３、カバー２５、駆動歯車２８、従動歯車３３、ばね３５などの要素に加えてタッチセンサ４１と軸部５１とを備える点、タッチセンサ４１の金属製のブラケット４２が回転操作体１３に金属製の止ねじ４３で前側から締結されたことでタッチセンサ４１が回転操作体１３に取り付けられた点、タッチセンサ４１の入力部が回転操作体１３の表面を被覆した図外の金属メッキに止ねじ４３およびブラケット４２を経由して接続された点、タッチセンサ４１の出力部に接続された被覆電線４４が回転操作体１３の裏側に引き出される点、回転操作体１３の裏側に引き出された被覆電線４４が回転操作体１３の裏側に固定された駆動歯車２８における大径筒部２９の内部と軸部３２の内部とグリップ本体１の軸受部４の内部および胴体部２の内部を経由してグリップ本体１の裏側に引き出される点、カバー２５の内部に軸受部２７を設けた点、軸受部２７と軸部５１との嵌め合いおよび軸部３２と軸受部４との嵌め合いで回転操作体１３がグリップ本体１とグリップ本体１に固定されたカバー２５とで両側支持構造に形成された点などが新規である。図１中の符号６１は回転操作体１３と駆動歯車２８とを結合する止ねじである。
【００１２】
図２を参照し、回転操作体１３と駆動歯車２８、軸部５１、タッチセンサ４１との取付構造について説明する。回転操作体１３における円板１４の裏面にはリブ６２が筒部１５や取付孔１７を囲むように突出して形成され、リブ６２には一対の切欠部６３が形成される。円板１４には逃孔６４および取付孔６５がリブ６２の周囲に位置するように形成される。図１に示すようにブラケット４２が止ねじ４３で回転操作体１３の前側に取り付けられた場合、逃孔６４はタッチセンサ４１で覆われるように、逃孔６４は回転操作体１３のタッチセンサ４１と対応する部分に設けられる。円板１４の裏面には周壁６６が逃孔１９やリブ６２を囲むように突出して形成される。回転操作体１３が図１のグリップ本体１とカバー２５とにそれらの間に挟まれるように回転可能に取り付けられる場合、図３に示すように、周壁６６が皿部３の周壁の内側に取り込まれ、リム２１が皿部３の周壁と前後方向に対向することで、グリップ本体１と回転操作体１３との合わせ部分からの不正操作部材の侵入を防止する。図２に示すように、軸部５１は後側に筒部１５の内部に内接嵌合されるように挿入される心棒５２を同軸状に備え、心棒５２の後端に一対の突起５３を心棒５２から径方向外側に突出するように備える。そして、軸部５１が回転操作体１３の裏側から筒部１５の内部に挿入されて図３に示すように回転操作体１３の前側に突出されることで、心棒５２が筒部１５に内接嵌合され、突起５３が切欠部６３に嵌め込まれることで、軸部５１が回転操作体１３に一緒に回転するように結合される。
【００１３】
図２において、駆動歯車２８は大径筒部２９の周壁前部に凹部６７を備え、大径筒部２９の周壁に開口部６８を備え、開口部６８と軸部３２の周壁とにわたってスリット６９を備える。そして、駆動歯車２８の脚部３１が回転操作体１３の裏側からリブ６２で囲まれた取付孔１７周りの裏面に突き当てられて図１の止ねじ６１で回転操作体１３に結合され、大径筒部２９の周壁が回転操作体１３に嵌め込まれた突起５３を裏側から押さえ付けることで、軸部５１が抜け止めされて回転操作体１３に結合される。突起５３と切欠部６３とは１個ずつの１組でもよいが、本実施形態のように心棒５２の直径線上に位置するように２組設ければ、駆動歯車２８による軸部５１の支持が安定する。回転操作体１３と駆動歯車２８とが互いに結合された場合、大径筒部２９の周壁とリブ６２と心棒５２との間には凹部６７による隙間が形成される。図２ではタッチセンサ４１から図１のブラケット４２を省略してある。タッチセンサ４１の裏面には被覆電線４４とタッチセンサ４１の出力部とを接続するコネクタ４５が配置される。
【００１４】
そして、被覆電線４４が回転操作体１３の前側から逃孔６４に挿入されて裏側に引き出され、コネクタ４５が逃孔６４に取り込まれ、図１のブラケット４２を回転操作体１３に取り付ける止ねじ４３が取付孔６５に締結されることで、タッチセンサ４１が回転操作体１３に固定される。回転操作体１３の裏側に引き出された被覆電線４４の延長端には図外のコネクタが結線されており、駆動歯車２８が回転操作体１３に結合された後では、当該図示を省略したコネクタが前記凹部６７による隙間を通過することができない。そのため、上記回転操作体１３の裏側に引き出された被覆電線４４に結合された図外のコネクタが回転操作体１３に結合される以前の駆動歯車２８の前側から大径筒部２９の内部と開口部６８を経由して大径筒部２９の外側に引き出され、回転操作体１３の裏側に引き出された被覆電線４４の中間部がスリット６９から軸部３２の内部を経由して駆動歯車２８の裏側に引き出される。その状態において、駆動歯車２８が凹部６７に被覆電線４４の中間部を取り込んだ状態で回転操作体１３に結合される。
【００１５】
本実施形態の構造によれば、図３に示すように、抵抗器軸１１に嵌め込まれた従動歯車３３と回転操作体１３に取り付けられた駆動歯車２８とが互いに噛み合わされ、回転操作体１３に取り付けられたタッチセンサ４１から延長した被覆電線４４が駆動歯車２８の内部とグリップ本体１における胴体部２の内部を経由してグリップ本体１の裏側に引き出され、回転操作体１３の前側に設けられた軸部５１とカバー２５の軸受部２７とが互いに嵌め合わされ、回転操作体１３の裏側に設けられた軸部３２とグリップ本体１の軸受部４とが互いに嵌め合わされ、ばね３５が図１のばね受部１８とばね止部６とに掛け止められ、支柱５と支柱２６とが図１の止ねじ３９で固定されることによって、回転操作体１３がグリップ本体１とカバー２５とにそれらの間に挟まれるように回転可能に取り付けられ、指掛部２２がグリップ本体１およびカバー２５よりも外側に配置された形態になる。
【００１６】
この図３に示すように組み立てられた球発射操作装置によれば、タッチセンサ４１からの信号を図外の遊技機枠に設けられた制御装置に出力する被覆電線４４が回転操作体１３の前側から回転操作体１３の回転中心に形成された駆動歯車２８の内部や軸部３２の内部を経由して回転操作体１３の裏側に引き出される構造であるため、回転操作体１３が球を発射しようとする遊技者で回転操作されても、被覆電線４４が回転操作体１３の回転に伴い旋回することはなく、被覆電線４４が回転操作体１３の動きを邪魔することもなく、遊技者が回転操作体１３を円滑に回転操作することができる。しかも、被覆電線４４が回転操作体１３の回転に伴い旋回することがないので、被覆電線４４が断線するような不都合も解消することができる。また、グリップ本体１とカバー２５との間に回転操作体１３をそれらの間に回転可能に挟む格好で、グリップ本体１とカバー２５とが互いに取り付けられることによって、軸受部２７と軸部５１との嵌め合いおよび軸部３２と軸受部４との嵌め合いで、回転操作体１３がグリップ本体１とカバー２５とで両側支持構造に支持されたので、遊技者が回転操作体１３を円滑に回転操作することができるうえ、回転操作体１３ががたつくことはなく、回転操作体１３がグリップ本体１とカバー２５との間に回転可能に安定に支持される。
【００１７】
回転操作体１３の前面に取り付けられるタッチセンサ４１と対応する部分に被覆電線４４を引き出すための逃孔６４が設けられているので、タッチセンサ４１を回転操作体１３に取り付けることによって、被覆電線４４とタッチセンサ４１のコネクタ４５とが逃孔６４から回転操作体１３の裏側に引き出されて存在することとなり、回転操作体１３とグリップ本体１とを回転可能に支持する軸部３２の内部および軸受部４の内部からグリップ本体１の裏側に被覆電線４４を容易に引き出すことができる。回転操作体１３とグリップ本体１とを回転可能に支持するために回転操作体１３に設けられた軸部３２と、回転操作体１３とカバー２５とを回転可能に支持するために回転操作体１３に設けられる軸部５１とが、互いに分割されているので、被覆電線４４が回転操作体１３とグリップ本体１とを回転可能に支持する軸部３２の内部および軸受部４の内部からグリップ本体１の裏側に引き出された状態において、回転操作体１３とグリップ本体１とを回転可能に支持する軸部３２と軸受部４とを互いに嵌め込むことができ、軸部３２の内部および軸受部４の内部に被覆電線４４を引き出す作業を容易に行うことができる。
【００１８】
図３中の符号７２は可変抵抗器８から延長された被覆電線であって、被覆電線７２も被覆電線４４と同様に図外の遊技機枠に設けられた制御装置に接続される。図３中の符号７３は胴体部２の裏面に設けれた位置決め突起であって、グリップ本体１が図外の遊技機枠に取り付けられる場合、突起７３が遊技機枠に設けられた凹部に挿入される。
【００１９】
本実施形態において、筒状の軸部３２を筒状の軸受部として形成し、筒状の軸受部４を筒状の軸部として形成することで、筒状の軸部３２と筒状の軸受部４とを互いに入れ替えても同様に適用することができる。要するに、軸部３２をグリップ本体１に設け、軸受部４を回転操作体１３に設けても同様に適用することができる。また、軸部５１を軸受部として形成し、軸受部２７を軸部として形成することで、、軸部５１と軸受部２７とを互いに入れ替えても同様に適用することができる。要するに、軸部５１をカバー２５に設け、軸受部２７を回転操作体１３に設けても同様に適用することができる。

Since the structure is drawn out to the back side of the rotary operation body through the formed escape hole, the covered electric wire rotates the rotation operation body every time the rotation operation body is rotated by a player who wants to launch a ball. Accordingly, there is a high possibility of not only obstructing the movement of the rotary operation body but also disconnecting it. 4 is formed by fitting a shaft portion 32 protruding rearward from the rotary operation body 13 to the bearing portion 4 of the grip body 1 so that the rotary operation body 13 is rotatably supported. In addition, since the rotating support body 13 is not smoothly rotated, there is a problem that the rotating operation body 13 is easily rattled.
