Claims

[Scope of utility model registration request]

A synchronization section that generates a synchronization signal, a transmission section that generates a transmission signal based on the output signal from the synchronization section, and a transmission section that converts the transmission signal generated from the transmission section into an ultrasonic signal and transmits the ultrasonic wave to the specimen. A probe that injects a sound wave and converts the reflected wave from the test material into an electrical signal, a receiver that amplifies the electrical signal from the probe, and an output signal of the receiver that converts the output signal into a predetermined signal. a comparison circuit that compares the level with the signal and outputs it as a pulse waveform; a gate generation section that generates a plurality of gate signals based on the output signal of the comparison circuit; and an output signal of the reception section that samples the output signal of the reception section using the output signal of the gate generation section. An ultrasonic flaw detection device characterized by comprising a sampling section.
