Abstract
Description
本発明の第1の実施形態について、図1乃至図3を参照して説明する。図1は、挿入機器1を示す図である。図1に示すように、挿入機器1は、挿入具である内視鏡2と、装着具であるスパイラルユニット10と、を備える。内視鏡2は、挿入部3を備え、挿入部3は、中心軸として長手軸Cを有する。ここで、長手軸Cに沿う方向(長手軸方向)の一方側が先端側(図1の矢印C1側)であり、先端側とは反対側が基端側(図1の矢印C2側)である。挿入部3は、長手軸Cに沿って基端側から先端側へ延設される。また、挿入部3は、外周面7を有する。内視鏡2では、挿入部3の基端側に操作部5が設けられる。また、操作部5には、ユニバーサルコード6の一端が接続される。
なお、回転体40のローラ(移動部材)42の数は、前述の実施形態等に限るものではない。すなわち、ローラ42(凸部47)の数は、1つ以上であれば、6つに限るものではない。
