<p>PROBLEM TO BE SOLVED: To invert tab paper without scratching it by providing a stopper which changes a position of the tab paper in accordance with a size of the paper in an inversion guide part and controlling the stopper in accordance with a length of a tab when the tab paper passes through. SOLUTION: A size stopper 31 stands by at a stop position for specified size, and a stopper motor 9 is turned on at the timing when a rear end of paper P passes through an inversion inlet sensor 8 and a tip of the paper P arrives at the size stopper 31 to push the paper P up. At this time, speed of an inversion drive motor 11 is reduced slightly to reduce a shock caused when the tip of the paper P collides against the size stopper 31. When a change-over claw 3 turns in the clockwise direction, the tip of the paper P bumps against the change-over claw 3 and is sent to an inversion guide part. When the change- over claw 3 turns in the counterclockwise direction, the paper P passes a path shown by A and is discharged by an outlet roller 16 as it is.</p> |
