PROBLEM TO BE SOLVED: To provide an endoscope system which can be placed in a predetermined position without damaging a treatment instrument and which facilitates the operation of an endoscope and the endoscopic operation of the treatment instrument. SOLUTION: In an endoscope system, a wire channel 24 formed at an end portion is formed up to the control part 5 of an endoscope and the rear end portion of a transmission wire 4 passed into the wire channel 24 is secured to the freely rotating shank 51a of a rotary operation wheel 51 serving as an operation means for generating an operating force for operating the treatment means of an endoscope module provided within the control part 5. The rotary operation wheel 51 is provided with a fixed knob 51b serving as a lock mechanism capable of setting the operating condition of the wheel selectively to a fixed condition or open condition. Thus, by rotating the rotary operation wheel 51, the transmission wire 4 is moved back and forth and the fixed knob 51b is operated to fix the transmission wire 4 in the desired position to maintain the operating condition.
