<p>According to the present invention, a capsule inducting system includes: a plurality of electrode pads (5) for performing human body communications with a capsule type endoscope (2) in a subject (1); a magnetic field generating part (15) generating a magnetic field for inducting the capsule type endoscope (2); a magnetic field change detecting part (17) detecting a time change rate of the magnetic field; a position calculating part (9) calculating a position of the capsule type endoscope (2) based on a voltage, detected by the electrode pads (5); and a control part (14) controlling an operation timing of the position calculating part (9). The control part (14) obtains the time change rate of the magnetic field from the magnetic field change detecting part (17) and stops the position calculating part (9) by recognizing that an eddy current is generated in the subject (1) by the magnetic field when the obtained time change rate exceeds a predetermined threshold value.</p> |
