ことを特徴とする。
ペン先側となる軸心方向の一端側に開口が設けられ、他端側が閉塞されている筒状の筐体を有し、少なくとも1本の電子ペン本体部が前記筒状の筐体内に収納されている電子ペンであって、
前記電子ペン本体部は、
軸心方向の一端側がペン先となる芯体と、
前記芯体の前記ペン先とは反対側に設けられ、コイルが巻回された磁性体コアと、
を備え、
前記ペン先となる前記芯体の一端側が前記筐体の開口から外部に突出している使用時には、前記磁性体コアの一部も前記開口から外部に突出する
ことを特徴とする。
図1は、この発明による電子ペンの第1の実施形態の構成例を示す図である。この第1の実施形態の電子ペン1は、筒状の筐体2の中空部2a内に、電子ペン本体部3が収納され、ノックカム機構部4により、電子ペン本体部3のペン先側が、筐体2の長手方向の一端の開口2b側から出し入れされるノック式の構成を備える。この実施形態では、電子ペン本体部3は、カートリッジ式の構成とされ、筐体2に対して着脱可能とされている。
図2は、電子ペン本体部3の構成例を、市販のノック式ボールペンの替え芯と比較して示す図である。すなわち、図2(A)は、市販のノック式ボールペンの替え芯6を示し、また、図2(B)は、この実施形態の電子ペン本体部3の構成例を示している。
この実施形態の電子ペン1おいては、芯体34の先端部34aが外部に突出する電子ペン1の使用時には、芯体34のみではなく、フェライトコア32の第1のコイル非巻回部32bの一部も筐体2の開口2bから突出しており、フェライトコア32のテーパー部32eの先端から、センサの入力面までの距離が短くなる。したがって、この実施形態の電子ペン1によれば、フェライトコア32が、筐体2の中空部2a内に留まっている従来の電子ペンに比較して、センサとの電磁結合が強くなる。さらに、この実施形態では、フェライトコア32の芯体34の先端部34a側は、テーパー部32eとされているので、フェライトコア32の先端の断面積が小さくなり、より磁束密度が大きくなって、センサと強く電磁結合するようになる。
次に、上述の実施形態の電子ペン1による指示位置の検出および電子ペン1に印加される筆圧の検出を行う位置検出装置400の回路構成例及びその動作について、図4を参照して説明する。
この第2の実施形態の電子ペンは、第1の実施形態の変形例である。上述した第1の実施形態では、電子ペン本体部を筐体内に1本のみを収納するようにした。この第2の実施形態では、筐体内に複数本の電子ペン本体部を収納させ、ノック機構により、その複数本の電子ペン本体部の内の1本を選択して、その選択した電子ペン本体部のペン先部の先端を、筐体のペン先側の開口から突出させて使用するようにする。
上述した第2の実施形態によれば、位置指示器は複数本の電子ペン本体部を収納することができると共に、電子ペン本体部のそれぞれは、自分自身のID信号を、位置検出装置に伝達することができる。そして、第2の実施形態の電子ペンと共に使用される位置検出装置においては、電子ペン本体部のID信号を検出することで、それぞれの電子ペン本体部に割り当てられた所定の機能処理を判別するが可能となって、非常に便利である。そして、第2の実施形態の位置指示器によれば、複数の電子ペン本体部を選択的に使用することで、位置検出装置側で機能選択をすることなく、種々の機能を実現することができるというメリットがある。
なお、上述の例では、電子ペン本体部3B,3R,3Eのスイッチ制御回路606は、位置検出装置400Mからの大レベルの電磁誘導信号を並列共振回路500で受信したときに、当該受信した大レベルの電磁誘導信号に基づき、スイッチ回路605をオンにするスイッチ制御信号を生成し、これにより、IC601に電源Vccを供給するようにした。
以上の実施形態においては、フェライトコア32の貫通孔32dを挿通された芯体34の端部34bが筆圧検出部35に嵌合されて、芯体34の先端部34aに印加された筆圧を、筆圧検出部35が検出するように構成されている。このため、フェライトコア32は貫通孔32dを備える必要があると共に、芯体34は、細長い棒状の部材とする必要があった。
以上は、電磁誘導方式の電子ペンの場合にこの発明を適用した場合である。しかし、この発明は、静電容量方式の電子ペンの例であるアクティブ静電ペンにも適用できる。以下に説明する第4の実施形態の電子ペンにおいては、フェライトコアに巻回されたコイルは、信号発信回路の電源を充電する充電回路の一部とされる。
・電極芯34Dに加えられる筆圧が阻害されることなく可変容量キャパシタ35Dに伝達される、
・充電用のコイル31Dの断面積を大きくすることができ、そのため充電を高速かつ効率良く行うことができる、
・充電用のコイル31Dと電極芯34Dを狭いスペースに配置することができ、静電方式スタイラスペンを細く作ることができる、
という効果を奏する。
上述の実施形態では、筆圧検出部は、筆圧に応じて静電容量を可変する可変容量キャパシタを用いるようにしたが、共振回路の共振周波数を変化させる変化素子であれば、インダクタンス値や抵抗値を可変するものであってもよいことは言うまでもない。
