PROBLEM TO BE SOLVED: To take out stacked sheets one by one by surely eliminating its blocking without any intervention of manpower. SOLUTION: A pair of right and left roller units 2 are provided movably to the top/bottom/right/left and the both roller units 2 are installed with upper rollers 18 and lower rollers 19 respectively. The lower rollers 18, in particular, are provided rotatably around the shafts of the upper rollers 18 and movable in the radial direction of the upper rollers 18. The upper roller 18R and the lower roller 19R of one roller unit 2 clamp a first end part of a sheet to bend it upward, the upper roller 18L and the lower roller 19L of the other roller unit 2 clamp a second end part of the sheet with the first end part clamped by the rollers, the lower roller 19L is turned to bend the second end part, and the lower roller 19L is continuously turned till all of the second end part is slipped out from an interval towards the upper roller 18L. By this constitution, the blocking of the end part of the sheet can be eliminated certainly. COPYRIGHT: (C)2003,JPO
