。(4) Structure of the Invention (4-1) Features of the Invention and Differences from the Prior Art In the present invention, when confirming the start and end of piping, an audible frequency (single articulation) is sent from the start and the end is detected. It is characterized by searching using a small microphone with an amplifier. Conventionally, methods such as drawing a road line or giving a hammering sound at the starting point and hearing the difference at the ending point were used, but it was often difficult to distinguish due to surrounding noise. The present invention can overcome this difficulty.
