<p>It is an object of the present invention to prevent, when a body-insertable apparatus system inserted into an internal organ of a subject is guided by a magnetic field, an excessive number of permanent magnets from being brought close to the subject. A housing apparatus (110) according to the invention includes housing units (111 to 116) which independently house permanent magnets (3a to 3f), respectively, lock units (111d to 116d) which bind the permanent magnets 3a to 3f in the housing units (111 to 116), respectively, magnetism detectors (111c to 116c) which detect whether the permanent magnets (3a to 3f) in the housing units (111 to 116), respectively, and a control unit (118). The control unit (118) controls the lock units (111d to 116d) in locking states or unlocking states on the basis of detection results of the magnetism detectors (111c to 116c).</p> |
