A plurality of arms are successively connected to a fixed arm so that the free end of the connected arms is movable three-dimensionally, a direct-access endoscope is attached to the three-dimensionally movable free end of the arms, and angle sensors are provided in the individual arm joints. Changes in angles between the individual arms due to the movement of the front end of the direct-access endoscope are sensed by the angle sensors, and the size and position of the object are numerically determined according to the changes.
