Description

  The present invention relates to a portable nondestructive inspection apparatus.

  Examples of portable nondestructive inspection apparatuses include an ultrasonic flaw detection apparatus and an eddy current flaw detection apparatus that search for flaws with ultrasonic waves and eddy currents. Among these, the one using ultrasonic waves includes flaw detection by a single probe provided with a single ultrasonic element and flaw detection by a phased array probe in which a plurality of ultrasonic elements are arranged.

Such a nondestructive inspection apparatus includes an LCD that displays various information such as flaw detection results (see, for example, Patent Document 1). For example, the result of a single probe is displayed on the monitor as a flaw detection waveform that expresses the size of the flaw as a numerical value, and the result of the phased array probe is a monitor display that displays the flaw detection waveform display and the tactical scan display that visually displays the flaw. This makes it easier for the inspector to judge the test result.
In addition, in the case of flaw detection in parts where it is difficult to see the flaw detection part inside the engine or the like, there are cases where the video scope is used together to display the image from the video scope or the flaw detection manual is displayed. The display items are very large.

However, in the case of the conventional non-destructive inspection apparatus, when the LCD is downsized (for example, about 6.5 inches) in order to reduce the size and weight, the display screen is displayed when the flaw detection result is displayed as a graph and an image. There is a problem that the screen is too small to see.
