Abstract
【解決手段】本発明の照光入力装置は、発光面から主発光軸に沿って光を照射する所定数の光源体と、概ね平行に対向する第1面及び第2面の間に概ね平行に位置すると共に所定数の光源体をそれぞれ収納する収納手段を内部に所定数備える平板状導光体とを含む照光装置と、ベース部材と、平板状導光体とほぼ同一形状の反射部材と、光源体が実装されるプリント基板と、光を透過させる入力部材と、入力部材のいずれかの場所が押圧されたとき押圧を感知する押圧感知部材とをさらに備える。
【選択図】図1
Description
図1の分解斜視図に示すように、照光入力装置LKは、プリント基板1、光源体2、導光体3、反射部材4、ベース部材5、入力部材6、押圧感知部材7、および減光部材8を含む。ベース部材5の上には、プリント基板1が載置されている。プリント基板1の上面には、4個の光源体2が実装されている。なお、光源体2は、その端面から概ね垂直な一方向に伸張する主発光軸Aに沿って光を照射する。説明の便宜上、4つの光源体2のそれぞれを、必要に応じて、光源体2_1、光源体2_2、光源体2_3、および光源体2_4と呼んで識別するものとする。
反射部材4の上に配置された導光体3には、4つの光源体2_1、2_2、2_3、および2_4のそれぞれが配置される4つの穴部3h_1、穴部3h_2、穴部3h_3、および穴部3h_4が載置されている。つまり、4つの光源体2_1、2_2、2_3、および2_4のそれぞれは、導光体3の対応する穴部3h_1、穴部3h_2、穴部3h_3、および穴部3h_4の内部に収容される。なお、穴部3hは、光源体2の発光側に面する側が円弧状に形成されている。
このように構成された状態で、入力部材6のいずれかの場所の入力キー6aが押圧されると、どの入力キー6aが押されたかが押圧感知部材7によって感知される。
