<p>PROBLEM TO BE SOLVED: To stack up single paper sheets on a stacker regulating front and rear, right and left, without slipping, slanting, clogging, or being mutually caught on the way of feeding, and enable the stacker of this construction to be used even for an automatic printing machine of different carrying method. SOLUTION: A round belt between a main driving roller 3 and a driven roller 4 is pushed up with an intermediate roller 7 so as to bend it chevron- likely, a fixed guide plate is fitted on one side of a feed conveyor on the driven roller of which a presser roller 9 is hung with a spring 14, an elevatable presser part 23 for a single paper sheet 16 is provided over the feed conveyor, a stop guide plate 28 for positioning and stopping the fed single paper sheet is fitted movably front and rear, and all these components are arranged on a frame. The frame is constituted movable in the perpendicular direction to the feed direction, the spring is hooked with the shaft of the presser roller so as to press the driven roller, and pressing of the driven roller can be released by pulling p the presser roller against a spring force.</p> |
