Abstract

PURPOSE:To simplify the structure and to enable diameter reduction and to facilitate the assembly by providing an image fiber main body externally with cylindrical direction fixing guides at intervals, running traction wires through >=1 traction wire insertion holes formed in its outer peripheral part and mounting this body in a coil spring. CONSTITUTION:While the traction wires 17 and 17 are not towed, an initial position in a linear state is maintained with the elastic restoring force of a coil spring 18. Then an oscillating operation means is put in operation to tow one traction wire 17 and loosen or free the other traction wire 17, and then the whole body curves toward the towing-side wire 17 against the elastic restoring force of the coil spring 18, so that an object head 12 swing in this direction. Further, when the head returns from the swing position to the initial position, the towing-side wire 17 is loosened and then the head returns automatically with the elastic restoring force of the coil spring 18. Consequently, the internal structure is simplified, the diameter of the whole body is reduced, and the assembly is facilitated.
