観察できる観察光学系とが配設されている。In these endoscopes, when the insertion section is inserted, an illumination optical system that transmits illumination light supplied to the proximal side and emits the illumination light to the object side on the distal end side of the insertion section; An observation optical system is provided that can form an image of the illuminated object and observe it from behind the eyepiece on the hand side.
上記内視鏡挿入部を体腔内あるいは管内等に挿入する場
合、安全性などの面から挿入深さを知ることが必要とな

従来、上記挿入部の挿入深さを知るためには、挿入部に
その先端からの距離を示す目盛を付し、必要時にこの目
盛の数字を読取るようにしていた。Conventionally, in order to know the insertion depth of the insertion section, a scale indicating the distance from the tip of the insertion section was attached to the insertion section, and the number on the scale was read when necessary.
しかしながら、このような手段によると、術者が挿入深

ならないのだが、目盛を見つけるのに手間が相るから非
常に不便であり、しかも、術者が内視鏡接眼部のファイ
ンダを覗いているときには目盛を読取るために挿入部の
方へ体を移動させなければならないから、非常に煩しく
作業性の低下を招くなどの欠点があった。However, with this method, whenever the operator wants to know the insertion depth, he or she has to read the scale each time, which is very inconvenient as it takes time and effort to find the scale. When the surgeon is looking through the finder of the eyepiece of the endoscope, he or she must move his/her body toward the insertion section in order to read the scale, which is very cumbersome and reduces work efficiency. Ta.

種の装置はこれまでなかった。In these conventional examples, the insertion depth of the insertion part can be known, but when the insertion part force (rotation (rotation) or twisting) is the same as the insertion, the observation direction of the insertion part tip 11111 is Particularly with strabismus-viewing or side-viewing endoscopes, there is a problem in that the target area cannot be observed quickly because the endoscope shifts.Also, treatment tools such as forceps are used for treatment. In some cases, if the direction in which the forceps are protruded is unclear, there is a risk of damaging the inner wall of the body cavity, making it impossible to perform prompt treatment, which is particularly problematic when an emergency is required. When it is necessary to always set the tip of the insertion tube at the same location, such as when periodically observing the target site to check for changes over time in the lesion, measure the insertion depth and rotation angle. Settings would be easier if there was a means for displaying the information appropriately, but there has never been a device of this kind.

By providing a reflective portion and a non-reflective portion, it is also possible to detect the amount of rotation. In this case, the reflecting part may be, for example, the conventional example (other) mentioned above.
As shown in (in the conventional example described above, the purpose is to know the insertion depth), it may be formed so that the amount of reflection changes depending on the rotational position.
