Abstract: An insertion device includes first and second magnet arrays facing each other with a gap therebetween, magnet supporting members adapted to support the magnet arrays mounted thereto, a gap driving mechanism for driving the first and second magnet supporting members in the vertical direction for changing the gap size, a driving conjunction mechanism for coupling the gap driving mechanism and the magnet supporting members to each other, compensation spring mechanisms adapted to compensate for attractive forces acting on the first and second magnet arrays, a spring conjunction mechanism for coupling the compensation spring mechanisms and the magnet supporting members to each other, a first supporting frame for supporting the gap driving mechanism, a second supporting frame for supporting the compensation spring mechanisms, and a common base placed on a placement surface, wherein the first supporting frame and the second supporting frame are individually coupled to the common base.

Abstract: A slide glass rack for use in a centrifugal apparatus has a slide glass accommodating concave that opens upward, and a flange provided on an upper outer peripheral surface of the rack. A centrifugal apparatus that uses the slide glass rack comprises a rotor, wherein the rotor is formed at a peripheral edge thereof with an inclined face extending upward obliquely with a predetermined angle, the inclined face being formed with a rectangular hole through which a slide glass rack is inserted, the flange of the rack is supported by the peripheral edges of the rectangular hole.
