Abstract

PURPOSE: To set a large degree of curve at a curved portion, prevent the diameter of an operating section from increasing and obtain secure curved operation by disposing a moving member on one side of the operating section, connecting an angle wire with the moving member, and disposing a guide member having a hole for passing and turning back the angle wire.
CONSTITUTION: A connector device 4a is connected to a connector receptacle 6a of a camera control device 6, and a connector 7a is connected to a connector receptacle 8a of a light source device 8 to transmit illumination light in the direction of fore-end 11. Inserting an insertion section 3, the fore-end 11 is brought near to a portion to be observed. When a finger piece 25 is slid toward the fore-end 11, a rod member 24 is slid, a link member 31 is moved, and a fixed portion of an angle wire 21 is moved in the direction opposite to a movable member 26 and tensioned. The portion of the angle wire 21 located from the point where a link member 31 is secured to the fore-end 11 is relaxed, a curved portion 10 is bent downward for example according to the sliding distance of the movable member 26, and the fore-end 11 is directed toward a portion to be observed.
