Abstract
Description
図9は、変形例1に係る入力装置1aの概略構成を示す平面図である。図10は、図9中に示したK2の部分を拡大した平面図である。図9および図10において、図3および図6と同様の機能を有する構成については、同じ参照符号を付記し、その詳細な説明を省略する。
図11は、変形例2に係る入力装置1bの概略構成を示す平面図である。図12は、図11中に示した切断線III-IIIに沿って切断した断面図である。図13は、図11中に示した切断線IV-IVに沿って切断した断面図である。図11~図13において、図3~図5と同様の機能を有する構成については、同じ参照符号を付記し、その詳細な説明を省略する。
上記では、基体2の第1主面2a側から入力操作する例について説明したが、これに限らない。例えば、基体2の第2主面2b側から入力操作してもよい。但し、この場合、保護層7上に、ガラスあるいはプラスチックからなる保護シートをさらに設ける必要がある。
なお、入力装置1の代わりに、入力装置1a,1bを電子機器X1に備えていてもよいし、入力装置1a,1bを備えた電子機器X1を携帯端末P1に備えていてもよい。また、入力装置1,1a,1bを適宜に組み合わせてもよい。
