Detecting system of position and posture of capsule medical device

A capsule medical device system comprising a posture detecting system for detecting the posture of a main body of a capsule medical device:

• the posture detecting system comprising:
• a coil in the capsule provided in the main body of the capsule medical device;
• a second magnetic field generating device for generating an alternating magnetic field to cause the coil in the capsule to generate an induced electromotive force;
• a magnetic field detecting device for detecting the strength of the magnetic field generated from the coil in the capsule;
• and
• a calculation processing unit calculating the posture and the position of the main body of the capsule medical device in response to a detection value from the magnetic field detecting device,
• wherein a primary side of a transformer is connected to a resonant circuit including a capacitor connected to the coil in the capsule, and a coil on a secondary side of the transformer is connected to a power supply circuit, and the power supply circuit supplies power to an internal circuit of the main body of the capsule medical device.
