Abstract
The endoscope apparatus comprises an endoscope which has an imaging element and a monitor which displays an image imaged by the imaging element. The endoscope is provided with an internal insertion portion which is movably arrangeable inside a body cavity, and an operation unit for changing the position of the internal insertion portion, which is arrangeable outside the body. The internal insertion portion and the operation unit are arranged on a common axis so as to interpose a body wall therebetween.

An endoscope apparatus comprising:
- an endoscope which has an imaging element and
- a monitor which displays an image imaged by the imaging element, wherein
- the endoscope is provided with an internal insertion portion which is movably arrangeable inside a body cavity, and an operation unit for changing the position of the internal insertion portion, which is arrangeable outside the body, and
- the internal insertion portion and the operation unit are arranged on a common axis so as to interpose a body wall therebetween, wherein
- the endoscope apparatus further comprises
- a rotational force transmission section for contactlessly transmitting the rotational force of the operation unit produced around an axial line between the internal insertion portion and the operation unit to the internal insertion portion.

- the internal insertion portion and the operation unit are arranged on a common axis so as to interpose a body wall therebetween, wherein
- the operation unit has a rotating section for rotating around an axial line between the operation unit and the internal insertion portion, and
- the internal insertion portion has a rotative member for contactlessly receiving the rotational force of the rotating section of the operation unit;
- and
- a driving-force-converting portion for converting the revolution of the rotating section into the rotation around an axis orthogonal to the axial line and transmitting the converted rotation to a portion including the imaging element.
