As the guidance system 301 for the capsule die medical device which depends on this invention, the magnetic field where it is generated to magnetic field generation section 2 has abbreviation uniform magnetic gradient from the peak magnetic field which restrains capsule die endoscope 10 in optional position and when changing to the uniform gradient magnetic field which the permanent magnet of capsule die endoscope 10 energization is done, makes the generation position of the horizontal plane of the said peak magnetic field magnetic field conditional storage section store 347, when the magnetic field where it is generated to magnetic field generation section 2 changing to the peak magnetic field from the uniform gradient magnetic field, the peak magnetic field is generated to the position where magnetic field conditional storage section 347 stores.本発明にかかるカプセル型医療装置用誘導システム301は、磁界発生部2に発生させる磁界をカプセル型内視鏡10を任意の位置に拘束するピーク磁界から略均一な磁気勾配を有しカプセル型内視鏡10の永久磁石を付勢する均一勾配磁界に切り替えるときに磁界条件記憶部347に該ピーク磁界の水平面の発生位置を記憶させるとともに、磁界発生部2に発生させる磁界を均一勾配磁界からピーク磁界に切り替えるときに磁界条件記憶部347が記憶する位置にピーク磁界を発生させる。
