PURPOSE: To widen the stereo base with simplified device constitution, by arranging a one side image forming plane of respective fiber scopes on the image forming plane of a plurality of lenses and taking the other side image forming plane as the same plane after the other image forming plane of the scopes is rotated.
CONSTITUTION: A plurality of images obtained by sequentially changing the angle of an objective 0 are formed on a lens of optical path selectors 51∼5N. One side image forming plane of fiber scopes 61∼6N is arranged with coincidence. After rotating another end of the scopes 61∼6N by 180°, the ends of the scopes 61∼6N are bonded to an image pickup surface 3f of a TV camera 3 and the image pickup surface 3f is taken as the same plane. The horizontal range of the selectors 51∼5N is widened than the surface 3f of the TV camera 3, a video signal S picked up with the camera 3 is applied to a stereoscopic picture display device 4 to display a plurality of images of the objective 0 of various modes on a fluorescent screen 4f with correct relation of position, allowing to widen the stereo base.
