Description
以下、図を用いて第1実施形態の内視鏡1について説明する。なお、図はいずれも説明のための模式図であり、縦横の寸法比等は実際とは異なっている。
最初に、配線板20が準備される。配線板20は、アルミニウムもしくは銅等の金属、ガラス、ガラス繊維含有エポキシ樹脂もしくはポリイミド等の樹脂、または、各種セラミックであってもよい。凹部21は、開口形状が矩形のため、4面の側壁(側面)および底部からなる。凹部21は、発光素子31の形状に応じて、その開口形状は多角形または円形等であってもよいし、壁面はテーパー形状でもよい。
次に、第1実施形態の変形例1、2の内視鏡1A、1Bについて説明する。変形例の内視鏡1A等は第1実施形態の内視鏡1と類似しているので同じ構成要素には同じ符号を付し説明は省略する。
次に、第2実施形態の内視鏡1Cについて説明する。内視鏡1Cは第1実施形態の内視鏡1と類似しているので同じ構成要素には同じ符号を付し説明は省略する。
次に、第2実施形態の変形例の内視鏡1Dについて説明する。変形例の内視鏡1Dは第2実施形態の内視鏡1Cと類似しているので同じ構成要素には同じ符号を付し説明は省略する。
また、内視鏡1Cでも、変形例の内視鏡1Dのように、異なる波長の光を出射する発光部が、独立してON/OFF制御可能であってもよい。
