1. A tubular body inspection system comprising:
- a carrying path in a loop form;
carrying means moving on said carrying path and capable of carrying a tubular body to be inspected;
transfer means provided at a position in the vicinity of said carrying path to transfer said tubular body to be inspected from outside onto said carrying means;
inspection means positioned one downstream side of said transfer means in the vicinity of said carrying path so as to be inserted into the tubular body to be inspected while moving together with said carried tubular body to be inspected to pick up an image of the internal surface of said tubular body to output a video signal thereof;
transmission means for taking out the video signal from said inspection means in a non-contact manner to transmit it;
image processing means to receive the transmitted video signal to discriminate a state of the internal surface of said tubular body to be inspected on the basis of the video signal whereby when said image processing means detects a defective article, it outputs a defective detection signal for specifying the defective article;
defective article rejection means positioned on downstream side of said inspection means in the vicinity of said carrying path to reject a corresponding defective article from said carrying mean in accordance with the defective detection signal; and
take-out means positioned on downstream side of the defective article rejection means in the vicinity of the carrying path for taking out said carried tubular body to be inspected from said carrying means to discharge it.

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.
