Abstract

PURPOSE:To automatically inspect the area and strength of a junction part with good accuracy by detecting the information mecessary for automatic discrimination from the multipath reflected waves which are actually obtained and performing data processing. CONSTITUTION:Only the multipath reflected wave signals reflected from the junction part of an object S to be measured are detected from the ultrasonic multipath reflected wave signals outputted from a pulser receiver U by a multipath reflected wave detecting circuit 31, and the quantity of the multipath reflected wave signals from the junction part and the prescribed value corresponding to a specified junction area are compared by a discriminating circuit 33, and whether the area of the junction part of the object S is above the specified value or not is discriminated. Thereby, the state of the junction part of the object S is automatically inspected.
