Abstract

PURPOSE: To provide an apparatus for feeding out stacked sheets, in which sheets are stacked on each other with their middle portions along the width thereof being dropped downward and the sheet is fed out of the stack while extending the sheet flat by applying forces in the direction of width of the sheet by means of feed-out rollers, whereby it is prevented that a pulrality of sheets are fed at a time.
CONSTITUTION: Sheets 7 are stacked on each other with their middle portions along the width of sheets 7 being dropped downward and they are retained at their top ends by stopper 11. Feed-out rollers 17a, 17b are held in contact with the upper surface of uppermost sheet 7a, and these rollers are turned in the direction of arrow B for feeding out sheet 7a in the direction of arrow C in the drawing. Further, these rollers 7 are both formed with a spiral groove for producing forces in opposite directions along the width of sheet 7a, so that sheet 7a is extended flat along with rotation of the rollers 7a, 7b. Tuhs, only the uppermost sheet 7a of the sheets 7 stacked with their middle portions being dropped downward substantially in a U-shape is extended flat and separated from the stack. Resultantly, the uppermost sheet 7a comes out of engagement with stopper 11 and can be fed forth from the stack.
