Abstract

PURPOSE:To facilitate the execution of a liquid permeating inspection even for a narrow part, by guiding a cable having an integral bundle of a fiberscope and hoses for feeding a permeating liquid or the like to an inspecting point with a guide tube. CONSTITUTION:A cable 11 has integral bundle of a fiberscope 21 and hoses 22a-22d for feeding a permeating liquid, cleaning liquid, developer and air for drying and the tip thereof is connected to a nozzle pad 23 to make a spraying to an inspecting point. To carry out an inspection, the cable 11 is fed into a guide tube 21 by the operation of a control panel 14 or the handling of a feeder 13 and pushed to the inspecting point. By the operation of pumps 34a-34d, the permeating liquid, cleaning liquid, developer and air for drying are sprayed to a surface to be inspected sequentially. Finally, the surface is observed with the fiber scope 21. This enables the performing of a liquid permeating deep flaw inspection at a narrow part in safety remotely from a central control room or other places with a better environment.
