Swirling vane wheel accumulating apparatus

A swirling vane wheel accumulating apparatus having an accumulation part for storing a paper sheet, comprising:

• entering means for entering the paper sheet in the accumulation part via an entrance slot of the accumulation part;
• stoppers arranged on an end side opposed to the entrance slot;
• a swirling vane wheel arranged between the entrance slot and the stoppers;
• a central upper guide member, arranged to extend from the entering means up to a position close to both sides of a rotational area of vanes of the swirling vane wheel, for guiding an upper surface of a central portion of the paper sheet entered in the accumulation part by the entering means while preventing the central portion from floating above;
• both ends lower guide members, arranged on both sides of the entering means, for guiding both ends of the paper sheet entered in the accumulation part by the entering means, and for causing the paper sheet to curve in a shape of U by lifting up both the ends;
• and
• an up-and-down stage that is positioned below the swirling vane wheel and arranged to be able to go up and down independently of the entering means, the stoppers, the swirling vane wheel, the central upper guide member and the both ends lower guide members, wherein
• the swirling vane wheel holds, in a gap between vanes, the paper sheet entered by being curved in the shape of U via the entrance slot, rotates the paper sheet, causes both the ends of the paper sheet, which extend off both sides of the vanes, to hit the stoppers so that the paper sheet is disengaged from the gap between the vanes and accumulated on the up-and-down stage.
