PURPOSE:To rapidly perform the confirmation of a flaw state, by recording the image signal only of the flaw place on a surface to be inspected. CONSTITUTION:A self-propelling vehicle 1 is arranged in a pipe 90 to be run and the running of the self-propelling vehicle 1 is controlled from the monitor 3 on a deck 92 while an inspection signal and an image signal are sent to a monitor part 3 to be monitored. An eddy current flaw detector supported by an shaking arm 44, the TV camera 5 for photographing the scanning range of the flaw detector 4 and an illumination lamp 50 are mounted to the front part of the self-propelling vehicle 1. The control part 71 for controlling the self-propelling vehicle 1 and a control circuit 70 for sending a drive signal to VTR 81 when a flaw is present on a surface to be inspected are mounted to an operation part 7. |
