第1実施形態にかかる操作入力装置は、例えば、携帯電話機(図示せず)に組み込むことにより、モニター内のスクロールバーをスクロールし、後述する押しボタン40等を介して選択指示を出すことができる。
なお、前記導電部21a~21eは、例えば、固定接点部が同心円状であってもよく、また、平面視略C字形の一方の固定接点部の中央に、他方の固定接点部を配置しておいてもよい。
なお、前記操作板45は、その上面に、後述する操作ダイヤル50の回動操作を円滑に行うための摺動シートを貼着一体化してもよく、摩擦抵抗の小さい樹脂材料を塗布してもよく、また、摩擦抵抗を小さくするために梨地加工を施しておいてもよい。
まず、図示しない治具である一対の位置決めピンに前記金属ベース10の治具孔13,14を挿入して位置決めする。ついで、ホール素子26,26を所定の位置に実装したプリント基板20の治具孔23,24を、前記治具の一対のピンに挿入することにより、前記金属ベース10の弾性係合受け部12に前記プリント基板20の係合孔22を嵌合して貼着一体化する。さらに、樹脂製フィルムカバー30の治具孔33,34を前記治具ピンに挿入し、前記プリント基板20の本体部20aに樹脂製フィルムカバー30を貼着一体化することにより、導電部21a~21eにドーム状反転バネからなる押しボタンスイッチ31a~31eをそれぞれ位置決めする。
なお、リング状固定具60の金属ベース10に対する固定方法は、弾性係合に限らず、カシメ固定、溶接固定であってもよい。
また、金属ベース10に、押しボタン40,操作ダイヤル50およびリング状固定具60を仮保持することなく、一方向から順次、組み付けできるとともに、金属ベース10に操作板45およびリング状固定具60をワンタッチで固定できる。このため、組立作業が容易で生産性に優れた操作入力装置が得られるという利点がある。
操作ダイヤル50を前記リング状固定具60の軸心を中心として回動させると、前記操作ダイヤル50は操作板45およびリング状固定具60に摺接しながら回動する。さらに、前記操作ダイヤル50と一体な環状マグネット53が回動し、一対のホール素子26が磁界の変化をそれぞれ検知し、これに基づいて回動方向および回動量を検出する。
そして、その検出結果が図示しない制御回路を介してモニターの画面表示にスクロールバーの移動として反映される。ついで、所望の位置にスクロールバーが到達した場合に、押しボタン40を押すことにより、中央押しボタンスイッチ31aの反転バネが反転し、対応する導電部21aを導通させて選択指令を出力する。
また、操作ダイヤル50の周辺部を押し下げ、操作板45の押圧用突起48で押しボタンスイッチ31b~31eの反転バネを適宜反転させることにより、対応する導電部21b~21eを導通させてもよい。
なお、前記操作板45は、その上面に、後述する操作ダイヤル50の回動操作を円滑に行うための摺動シート49を貼着一体化するが、摩擦抵抗の小さい樹脂材料を塗布してもよく、また、摩擦抵抗を小さくするために梨地加工を施しておいてもよい。
したがって、前記切り欠き部52aのいずれかに環状マグネット53のバリ部53aを嵌合し、残る他の切り欠き部52aに接着剤を注入,固化することにより、前記操作ダイヤル50に環状マグネット53を固定する。なお、前記操作ダイヤル50は、必ずしも円形である必要はなく、回動可能であれば、例えば、正八角形であってもよい。
まず、図示しない治具である一対の位置決めピンに前記金属ベース10の治具孔13,14を挿入して位置決めする。ついで、ホール素子26,26を所定の位置に実装したプリント基板20の治具孔23,24を、前記治具の一対のピンに挿入することにより、前記金属ベース10の弾性係合受け部12に前記プリント基板20の係合孔22を嵌合して貼着一体化する。さらに、樹脂製フィルムカバー30の治具孔33,34を前記治具ピンに挿入し、前記プリント基板20の本体部20aに樹脂製フィルムカバー30を貼着一体化することにより、導電部21a~21eにドーム状反転バネからなる押しボタンスイッチ31a~31eをそれぞれ位置決めする。
なお、リング状固定具60の金属ベース10に対する固定方法は、弾性係合に限らず、カシメ固定、溶接固定であってもよい。
また、金属ベース10に、操作板45、操作ダイヤル50、リング状固定具60および押しボタン40を仮保持することなく、一方向から順次、組み付けできるとともに、操作板45、リング状固定具60および押しボタン40を、ワンタッチで固定できる。このため、組立作業が容易で生産性に優れた操作入力装置が得られるという利点がある。
