<p>PROBLEM TO BE SOLVED: To easily adjust a pressing pressure in a state of holding an airtightness in an apparatus by a method wherein an eccentric sleeve is rotated by a rotating means, a vertical transfer of a pressing roll is changed by adjusting its rotary angle, and a pressing force of the pressing roll is adjusted. SOLUTION: Shafts 15, 16, bearings 17, 18 and eccentric sleeves 19, 20 are fitted to both ends of a pressing roll 11, and fixing sleeves 21, 22 fitted outside the eccentric sleeves 19, 20 are fixed to a chamber partition wall 25. When at first a down side stepping motor 30 is moved, gears 23, 24 are rotated by gears 29, 27, 28 and a driving shaft 26, the pressing roll 11, the shafts 15, 16, the bearings 17, 18 and the eccentric sleeves 19, 20 are integrally rotated, and the pressing roll 11 moves upward. At that time, the eccentric sleeves 19, 20 are rotated by 90 degree, and an outer diameter of the down side pressing roll 11 is transferred to a specimen carrying surface 32. Then, the upper side pressing roll 11 is moved in the same way, and a clearance between the upper and lower pressing rolls 11 is adjusted.</p> |
