Sheet post-process apparatus

Abstract

A sheet post-process apparatus of the present invention has a standby tray for stably dropping sheets of paper onto a processing tray, and a pair of tray members for loading ejected sheets of paper are formed so as to project from the wall face of the standby tray, and on the surfaces of the tray members, a projection having an inclination to the lower end of the paper laminations up to the upper end thereof is formed in the conveying direction of the sheets of paper P.

1 . Sheet post-process apparatus comprising: 
 a standby tray for making sheets ejected from an image forming apparatus stand by,    a processing tray arranged under said standby tray for loading said sheets dropped and fed from said standby tray and/or said sheets ejected from said image forming apparatus not via said standby tray,    a processing mechanism for post-processing said sheets loaded on said processing tray, and    a paper ejection tray for loading said sheets ejected from said processing tray after ending of said post process, wherein:    said standby tray is formed so that a pair of tray members for loading said ejected sheets are projected from a wall face of said standby tray and on a surface of said tray members, a projection inclined to an interval from a lower end of said stacked sheets to an upper end thereof is formed in a conveying direction of said sheets.    
   
   
       2 . The sheet post-process apparatus of  claim 1 , wherein: 
 said projection is formed on said tray members on a front end side of said sheets.    
   
   
       3 . The sheet post-process apparatus of  claim 1 , wherein: 
 said projection has a length equivalent to about ⅓ of a length of said tray members.    
   
   
       4 . The sheet post-process apparatus of  claim 1 , wherein: 
 said projection has a width equivalent to about ⅔ of a width of said tray members.    
   
   
       5 . The sheet post-process apparatus of  claim 1 , wherein: 
 said projection is formed in a curved convex shape.    
   
   
       6 . The sheet post-process apparatus of  claim 1 , wherein: 
 said projection is formed in an inverted triangular columnar shape.    
   
   
       7 . The sheet post-process apparatus of  claim 1 , wherein: 
 said projection is formed in a cone shape.    
   
   
       8 . The sheet post-process apparatus of  claim 1 , wherein: 
 said tray members and said projection are formed integrally with each other.    
   
   
       9 . The sheet post-process apparatus of  claim 1 , wherein: 
 said pair of tray members, when loading sheets curled downward, rotate upward and when loading sheets curled upward, rotate downward.
