    Abstract: A curved shape sensor to detect a curved shape of a measured object includes a light source to emit detection light, an optical fiber to guide the detection light, a detection part provided at a portion of the optical fiber, a rotation suppressing member fixed to the optical fiber, and a light detection unit to detect the detection light traveling through the optical fiber. The measured object includes a tubular member having flexibility so as to be curved, and an incorporation member located inside the tubular member. The detection part changes characteristics of the detection light in accordance with a change in a curvature of the optical fiber. The rotation suppressing member is located within a space defined by the tubular and incorporation members with being in contact with them, so as to suppress rotation of the optical fiber.

    Abstract: An endoscope apparatus includes an endoscope including a flexible insertion tube and a curved-shape detection sensor. The curved-shape detection sensor includes an optical fiber for propagating detection light and a sensing part provided in at least a part of the optical fiber. The curved-shape detection sensor detects a curved shape of the insertion tube based on a change of characteristics of the detection light after passing the sensing part made in accordance with a change in a curved shape of the optical fiber when the optical fiber is curved. The optical fiber is arranged on a curve axis of the insertion tube defined when the insertion tube is curved in a predetermined curve direction, or in a proximity region of the curve axis.

    Abstract: A bending apparatus includes a shape sensor including a light source, an optical fiber, a detecting part, and a light receiver. The shape sensor utilizes a variation in optical characteristics, which is detected by the detecting part in accordance with a variation of curvature of the optical fiber when the optical fiber is bent. The shape sensor is freely bendable in any direction and having directivity in detection sensitivity for a bending direction. A bending direction restriction mechanism is combined with the shape sensor and has bending directivity including such a property of ease in bending that bending is easy in at least a specific direction other than a direction of a center line, and such a property of difficulty in bending that bending is difficult in directions other than the specific direction.
