PROBLEM TO BE SOLVED: To provide an endoscope which is excellent in workability when an endoscopic treatment is performed by projecting an endo-therapy accessory from the distal end opening of a channel for the passing of a plurality of endo-therapy accessories. SOLUTION: A projecting amount of the endo-therapy 44 which is projected from the opening 19a, is placed under a state wherein the endo-therapy 44 is projected, e.g. by approximate 15 mm from a slope 2a which is the distal end surface of a distal end rigid member 2. In this case, approximate 15 mm is a specified amount which is considered to be a most easily operable amount, while being not too close and not too far, in the operation of the treating utensil when a demucosation is performed. Then, a second treating utensil rocking base 15 is turned by pull-controlling wires 24 and 25. Thus, the distal end section of the endo-therapy 44 moves without exceeding a lateral observation visual field range of an observation window 3. Therefore, an endo-therapy image 44a, which is displayed on an endoscope image, turn-moves in both of right and left directions within the endoscope image range as shown by solid line arrow in such a manner that the distal end of the treating utensil may draw a distal end track 51 shown by a double dot broken line from the neutral state location shown by a solid line. |
