- a technique for detecting a conductive foreign object by supplying a signal of about 10 KHz to 100 KHz to the coil as described above is well known as a technique used when exploring a metal body buried in soil, for example. Therefore, in order to avoid complication of explanation, only a simple explanation is given.
- the frequency change level detected at this time is stored in the memory 47. That is, in the foreign substance confirmation mode, when the detection level of the frequency change amount is higher than the threshold value, the control unit 10 confirms the presence of the foreign substance again in the foreign substance confirmation period (mode B) shown in FIG. When the detected frequency change level is continuously higher than the threshold value a plurality of times, the control unit 10 turns on the foreign object alert flag (S200, S300 in FIG. 13).
