<p>PURPOSE:To disperse a stress collected to a rotating support point by forming the rotating support point of an armor member 3 and the rotating support point of a sheet stacking base separately, and connecting and interlocking the facing member with the rotation of the stacking base by a connecting member. CONSTITUTION:The rotating support point 3a of an armor member 3 and the rotating support point 2a of a sheet stacking base 2 are separately formed, and the rotating support point 2a forms also as the oscillating support point of a pressurizing means 5. The sheet stacking base 2 has bosses 2b on both the sides, which are fitted and connected to elliptic holes 3b provided on both sides of the armor part 3 to form a connecting system H. At the time of stacking sheets, the armor member 3 is rotated from a position A to a position B and opened, and the sheet stacking base 2 connected by the connecting system H is also rotated with the support point 2a as the center interlockingly therewith to make the sheets possible to be stacked. According to this constitution, as the armor member 3 and the stacking base 2 are rotated with different rotating support points 3a, 3b, stress collection is dispersed, and the breakage of the rotating support points can be prevented.</p> |
