PURPOSE:To automate an inspecting work by detecting regular reflected light by a leak foam, by two sensor arrays in the X-Y directions, deriving the X-Y coordinates, and displaying a leak position. CONSTITUTION:Plural objects to be inspected 5 are submerged onto the bottom face of a liquid tank 3, and generation of a foam from the object to be inspected of sealing-up failure is quickened by heating the object to be inspected 5 by a heater part 6. When the foam rises and is positioned on a detecting plane A of X and Y sensor arrays 7, 8, light from an illuminating device 1 is regularly reflected by the surface of the foam, and made incident to one sensor of the sensor arrays corresponding to the foam generated position. The sensor arrays 7, 8 are constituted so that parallel lights are made incident into the long cylindrical direction, therefore, the light which is made incident by being regularly reflected by a foam B is irradiated to a photosensor 10 provided on the end of a long cylinder 9 and detected. |
