Claims (5)
- 検出面上において指示体の指示位置座標を検出する光デジタイザであって、該光デジタイザは、
光線を発するための光源と、
前記検出面の周囲の少なくとも3辺を包囲するように設けられる、又は前記指示体に設けられる、前記光源から発せられた光線を再帰反射する再帰反射部材と、
前記光源から発せられ前記再帰反射部材から再帰反射された光線を利用して、前記指示体を撮像し電気信号に変換するためのイメージセンサからなる撮像手段と、
前記検出面に対する垂直方向の厚さを薄くするために、光軸に対して回転対称なレンズを光軸に対して平行に上下をスライスしてその上下に平面を有する形状とした、前記撮像手段に結像するための結像レンズと、
からなり、前記光源の発する光線の光軸と前記結像レンズの光軸とを近づけるために、前記光源は、前記結像レンズの上平面に近接して設けられ、結像レンズの下平面が前記検出面を形成する入力平面上に平行に固定される、又は前記結像レンズが入力平面板と一体成型されることを特徴とする光デジタイザ。 - 請求項1に記載の光デジタイザであって、前記結像レンズは、その光の入射側の前面に絞りが設けられることを特徴とする光デジタイザ。
- 請求項1又は請求項2に記載の光デジタイザであって、前記結像レンズと前記撮像手段の間に、前記結像レンズからの光を90度屈折させて前記撮像手段に結像するためのミラー手段を更に有することを特徴とする光デジタイザ。
- 請求項1乃至請求項3の何れかに記載の光デジタイザであって、前記検出面に積置される表示面を持つ表示装置を更に有することを特徴とする光デジタイザ。
- 請求項4に記載の光デジタイザであって、前記表示装置は、反射型液晶表示装置であることを特徴とする光デジタイザ。
