Abstract: A capsule-type medical device comprises a capsule main unit having functions for being inserted into the body cavity and performing medical acts such as taking images or the like. The capsule main unit comprises therein a magnet which is acted upon by external magnetism, and a spiral portion on the outer perimeter, so that rotating force acting upon the magnet is readily converted into a propelling force for propelling the capsule-type medical device. A flexible insertion portion which is long and small in diameter is provided to the capsule main unit to allow smooth progression through the body cavity, and the center of gravity of the device is placed upon the longitudinal center axis of the capsule main unit, thus facilitating smooth progression through the body cavity.

Abstract: A guidance device includes: a permanent magnet; an accommodating portion; a shielding member configured to shield the magnetic field generated by the permanent magnet; a supporting mechanism configured to support the permanent magnet between a first position and a second position; a driving unit configured to operate the supporting mechanism upon receiving an electric power supply; and a shielding member moving mechanism configured to move the shielding member between a shielding position and a non-shielding position in conjunction with an operation of the supporting mechanism causing the permanent magnet to move in a vertical direction. When the electric power supply to the driving unit stops, the shielding member moving mechanism moves the shielding member to the shielding position in conjunction with an operation of the supporting mechanism causing the permanent magnet to move to the first position.
