Abstract
While carrying and rotating a tubular body to be inspected, an image pick up device is inserted into the tubular body to be inspected to pick up an image of the internal surface thereof to take out a corresponding video signal to transmit the video signal to an image processing device through an antenna device to carry out image processing to judge the internal surface of the tubular body to be inspected. In the antenna device ring-shaped conductors are oppositely arranged in a ring-shaped hollow chamber provided within an electromagnetic shielding body wherein one ring-shaped conductor is rotated and the other is fixed.
