Sheet media storage device and sheet media processing device

Abstract

A sheet media processing device has a storage pocket. A feed roller for conveying checks into the storage pocket is disposed beside the upstream-side end wall of the storage pocket. The feed roller has a main roller part and a small roller part that is smaller in diameter than the main roller part. A reverse feed prevention plate disposed to the end wall covers at least part of the gap between the end wall and the feed roller. The distal end of the reverse feed prevention plate extends to a position between the outside surface of the main roller part and the outside surface of the small roller part.

1 . A sheet media storage device comprising:
 a storage pocket for storing sheet media; and   a feed roller for conveying the sheet media into the storage pocket;   wherein the storage pocket has a reverse feed prevention member that closes at least a part of a gap between the storage pocket and the feed roller.   
   
   
       2 . The sheet media storage device described in  claim 1 , wherein:
 the feed roller includes a main roller and a small roller part that is smaller in diameter than the main roller; and   the reverse feed prevention member extends from the storage pocket toward an outside surface of the small roller part.   
   
   
       3 . The sheet media storage device described in  claim 1 , wherein:
 the feed roller includes a main roller and a small roller part that is smaller in diameter than the main roller;   the reverse feed prevention member extends from the storage pocket toward an outside surface of the small roller part; and   a width of a distal end part of the reverse feed prevention member is substantially equal to or slightly smaller than a width of the small roller part.   
   
   
       4 . The sheet media storage device described in  claim 1 , wherein:
 the feed roller has a feed pin protruding radially from an outside surface of the feed roller.   
   
   
       5 . The sheet media storage device described in  claim 1 , further comprising:
 a pressure roller that pushes the sheet media to the feed roller.   
   
   
       6 . A sheet media processing device comprising:
 a sheet media transportation path for conveying sheet media; and   a sheet media storage device as described in  claim 1  for storing the sheet media conveyed through the sheet media transportation path.   
   
   
       7 . A sheet media storage device comprising:
 a storage pocket for storing sheet media; and   a feed roller for conveying the sheet media into the storage pocket;   wherein the storage pocket has a reverse feed prevention guide surface spanning from an upstream end wall of the storage pocket to an end part of the feed roller.   
   
   
       8 . The sheet media storage device described in  claim 7 , wherein:
 the reverse feed prevention guide surface is positioned near a tangent to an outside surface of the feed roller.   
   
   
       9 . The sheet media storage device described in  claim 7 , wherein:
 the feed roller has a feed pin protruding radially from an outside surface of the feed roller.   
   
   
       10 . The sheet media storage device described in  claim 7 , further comprising:
 a pressure roller that pushes the sheet media to the feed roller.   
   
   
       11 . A sheet media processing device comprising:
 a sheet media transportation path for conveying sheet media; and   a sheet media storage device as described in  claim 7  for storing the sheet media conveyed through the sheet media transportation path.   
   
   
       12 . The sheet media storage device described in  claim 2 , wherein the reverse feed prevention member is a reverse feed prevention plate ( 53 ) that extends between an outside surface of the main roller ( 41 ) and an outside surface of the small roller ( 42 ). 
   
   
       13 . The sheet media storage device described in  claim 2 , wherein a plurality of small roller parts ( 42 ) are disposed along an axial length of the feed roller ( 40 ). 
   
   
       14 . The sheet media storage device described in  claim 2 , wherein the reverse feed prevention member is a reverse feed prevention plate ( 53 ) that is disposed perpendicular to a rotational axis of the feed roller ( 40 ).
