Description
以上説明した実施の形態の画像読取装置300は各種の変形が可能である。まず、第1に、図5に示した光学系では第1〜第4の反射ミラー206〜209を用いて光線の反射を行ったが、光学レンズユニット211と上下に重ならないような配置空間内に、反射ミラーを適宜の枚数で配置することによっても、薄型の画像読取装置300を実現することができる。また、本実施の形態では2個の反射ミラーについてこれらの2箇所で光線の反射を行うことにしたが、1個の反射ミラーについてその2箇所で光線の反射を行うようにしてもよいし、3個の反射ミラーについてその2箇所で光線の反射を行うようにしてもよい。もちろん、反射ミラーのいずれかについて3箇所で光線の反射を行うことも光路長の増大に貢献することができる。
