<P>PROBLEM TO BE SOLVED: To provide a bio-magnetic field measuring apparatus which detects bio-magnetic signals of a fetus safely in a highly sensitive manner by bringing a sensor surface closer to an abdominal wall of a mother safely and accurately. <P>SOLUTION: The bio-magnetic field measuring apparatus includes a gate-shaped, first supporting body 102 having two leg parts and a connecting part for connecting across an upper part between two leg parts, a cylindrical cryostat 103 provided between two leg parts under the connecting part, a detecting sensor 701 provided from the inside of the cryostat towards the end for detecting a bio-magnetic field, a second supporting body 301 which is supported by the first supporting body and controls the rotations of the cryostat using a direction of connecting two leg parts as the rotational axis, a third supporting body 302 which is supported by the second supporting body and controls the movements of the cryostat in the axial direction, driving means 401a, 401b, 501 for respectively driving the second and third support bodies, and a control means 106 for controlling the driving means. <P>COPYRIGHT: (C)2008,JPO&INPIT |
