PURPOSE:To rotate an image rotator in the direction opposite to the rotating direction of a side view body on an axis X-X, so that the direction of an image formed on the end part of a fiber scope becomes the same as the regular direction of an object to be photographed, and also the direction of the formed image does not rotate. CONSTITUTION:An image rotator 3 is placed between a side view body 1 and an objective lens 7 so that the center of a rotation of the image rotator 3 coincides with the center of fiber scope 2. Also, the image rotator 3 is rotated on an axis X-X. A rotational angle in this case is W/2 which is half of a rotational angle W of the side view body 1 and said image rotator is rotated in the opposite direction. In this way, the image rotator 3 for changing the direction of the image is provided on the axis X-X of the side view body 1 and the fiber scope 2, and rotated in the direction opposite to the rotating direction of the side view body 1, so that the direction of the image formed on an end part 4 of the fiber scope 2 is changed. |
