Abstract

A stacking wheel mechanism ( 30 ) includes a stacking wheel ( 32 ) that is arranged near a stacking unit ( 26 ) and having a plurality of elastic blades ( 32 a ) on an outer circumferential surface thereof, and a blade guiding member ( 38 ) that is arranged near the stacking wheel ( 32 ) to guide the blades ( 32 a ) of the stacking wheel ( 32 ). The blade guiding member ( 38 ) guides the blades ( 32 a ) of the stacking wheel ( 32 ) such that the blades ( 32 a ) of the stacking wheel ( 32 ) enter into a transport path (for example, an internal transport path ( 36 )) when the stacking wheel ( 32 ) rotates in a feeding-in direction of a paper sheet toward the stacking unit ( 26 ) and the blades ( 32 a ) of the stacking wheel ( 32 ) retreat from the transport path when the stacking wheel ( 32 ) rotates in a feeding-out direction of the paper sheet from the stacking unit ( 26 ).

First claim

1 . A stacking wheel mechanism for use in a paper sheet stacking and feeding apparatus for stacking a paper sheet in a stacking unit and feeding out the paper sheet from the stacking unit, comprising:
a transport path along which the paper sheet passes during both of stacking the paper sheet in the stacking unit and feeding out the paper sheet from the stacking unit; a stacking wheel arranged near the stacking unit so as to be rotatable in both of a feeding-in direction of the paper sheet toward the stacking unit and a feeding-out direction of the paper sheet from the stacking unit, the stacking wheel having a plurality of elastic blades on an outer circumferential surface thereof; and a blade guiding member that is arranged near the stacking wheel to guide the blades of the stacking wheel such that the blades enter into the transport path when the stacking wheel rotates in the feeding-in direction of the paper sheet toward the stacking unit and the blades retreat from the transport path when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit.

2 . The stacking wheel mechanism according to claim 1 , wherein the blades of the stacking wheel are bent by contacting the blade guiding member when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit and retreat from the transport path.

3 . The stacking wheel mechanism according to claim 1 , wherein the blade guiding member is configured so that, when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit, the blades of the stacking wheel deform in an axial direction of the stacking wheel by contacting the blade guiding member.

4 . The stacking wheel mechanism according to claim 1 , wherein the blade guiding member is a plate-like member inclined to a surface that is parallel to the axial direction of the stacking wheel and a surface that is orthogonal to the axial direction.

5 . The stacking wheel mechanism according to claim 4 , wherein the blade guiding member is configured so that, the blades of the stacking wheel contact one surface of the blade guiding member when the stacking wheel rotates in the feeding-in direction of the paper sheet toward the stacking unit, and the blades of the stacking wheel contact another surface of the blade guiding member when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit.

6 . The stacking wheel mechanism according to claim 1 , wherein a surface of the blade guiding member where the blades of the stacking wheel contact when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit is formed into a concave shape.

7 . The stacking wheel mechanism according to claim 1 , further comprising a paper-sheet guiding member that guides the paper sheet so that the paper sheet is transported along the transport path, wherein
an axis of the stacking wheel is arranged on one side and the transport path is arranged on the other side of the paper-sheet guiding member, and the blade guiding member is fixed to the paper-sheet guiding member.

8 . The stacking wheel mechanism according to claim 7 , wherein
the paper-sheet guiding member is provided with an opening through which the blades of the stacking wheel pass, the blades of the stacking wheel enter into the transport path by passing through the opening in the paper-sheet guiding member when the stacking wheel rotates in the feeding-in direction of the paper sheet toward the stacking unit, and the blades of the stacking wheel are guided by the blade guiding member so that the blades contact the surface of the paper-sheet guiding member that is on another side to the side on which the transport path is present whereby the blades do not pass through the opening in the paper-sheet guiding member when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit.

9 . The stacking wheel mechanism according to claim 8 , wherein a part of the surface of the paper-sheet guiding member, which is on the other side of the side on which the transport path is present, where the blades of the stacking wheel contact when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit is formed into a concave shape.

10 . The stacking wheel mechanism according to claim 8 , wherein
a base part of the blade guiding member is fixed to the paper-sheet guiding member near the opening in the paper-sheet guiding member, and a tip end portion of the blade guiding member extends toward the opening in the paper-sheet guiding member with respect to an axial direction of the stacking wheel.

11 . The stacking wheel mechanism according to claim 8 , wherein, the blade guiding member blocks a portion of the opening in the paper-sheet guiding member, when seen along a direction that is at a right angle to the axial direction of the stacking wheel.

12 . The stacking wheel mechanism according to claim 8 , wherein the blade guiding member is inclined with respect to the opening in the paper-sheet guiding member.

13 . The stacking wheel mechanism according to claim 8 , wherein the blade guiding member is arranged at a position where, when the stacking wheel rotates in the feeding-out direction of the paper sheet from the stacking unit, the blades of the stacking wheel contact the blade guiding member just before the blades arrive at the opening in the paper-sheet guiding member from a region on one side of the paper-sheet guiding member with the transport path present on the other side.

14 . The stacking wheel mechanism according to claim 7 , wherein the opening in the paper-sheet guiding member has a region through which a part of the blades of the stacking wheel that has been bent by contacting the blade guiding member passes, when the stacking wheel rotates in the feeding-in direction of the paper sheet toward the stacking unit.

15 . A paper sheet stacking and feeding apparatus comprising:
the stacking wheel mechanism according to claim 1 ; a feeding roller that performs feeding in of the paper sheet toward the stacking unit and feeding out of the paper sheet from the stacking unit; and a gate roller arranged opposing the feeding roller and which transports the paper sheet therebetween when stacking the paper sheet in the stacking unit and separates paper sheets one by one when feeding out the paper sheets from the stacking unit.

16 . A paper sheet handling method implemented on a paper sheet stacking and feeding apparatus for stacking a paper sheet in a stacking unit and feeding out the paper sheet from the stacking unit, comprising:
fixedly arranging a blade guiding member near a stacking wheel, the stacking wheel being rotatable in both of a feeding-in direction of the paper sheet toward the stacking unit and a feeding-out direction of the paper sheet from the stacking unit and having a plurality of elastic blades on an outer circumferential surface thereof, to guide the blades of the stacking wheel; causing the blades of the stacking wheel to enter into a transport path of the paper sheet when stacking the paper sheet in the stacking unit; and causing the blades of the stacking wheel to retreat from the transport path when feeding out the paper sheet from the stacking unit.

17 . The paper sheet handling method according to claim 16 , wherein the blade guiding member is fixed to a paper-sheet guiding member that guides the paper sheet so that the paper sheet is transported along t
