Paper storage apparatus

Abstract

Paper storage apparatus is provided with friction members that are provided at opposing sides ( 7 c ) of a lifting table ( 7 ) facing a pair of guide rails ( 3, 4 ) such that the friction members ( 30, 31 ) project toward the guide rails ( 3, 4 ). When a paper ( 10 ) is moved by the lifting table ( 7 ) so that end portions of the paper ( 10 ) escape from the grooves ( 3 a, 4 a ), the paper ( 10 ) slides while being in contact with the friction members ( 30, 31 ), thereby to prevent the paper ( 10 ) from being moved on the lifting table ( 7 ).

What is claimed is:  
     
         1 . An paper storage apparatus for storing sheets of paper, comprising: 
 a pair of guide rails arranged with a predetermined space therebetween and formed with guide grooves that guide opposing end portions of a paper;    a lifting table that moves into and out from the space between the pair of guide rails; and    a stacker for storing the paper,    wherein the paper guided into the guide grooves of the pair of guide rails is loaded and stored in the stacker by escaping the paper from the pair of guide grooves by the lifting table,    characterized in that the paper storage apparatus further comprises friction means respectively disposed at opposing sides of the lifting table facing the pair of guide rails in such a manner as to project toward the guide rails, wherein, when the paper escapes from the grooves by an action of the lifting table, the paper slides while being in contact with the friction means, thereby to prevent the paper from being moved on the lifting table.    
     
     
         2 . The paper storage apparatus according to  claim 1 , wherein the friction means comprises a tongue-shaped elastic member made of elastic rubber.  
     
     
         3 . The paper storage apparatus according to  claim 1 , wherein the friction means comprises a tongue-shaped elastic member made of elastic rubber and a projection disposed on an upper surface of the lifting table at a position corresponding to the elastic member.  
     
     
         4 . The paper storage apparatus according to  claim 1 , wherein the friction means is provided at opposing sides of the lifting table, respectively.  
     
     
         5 . The paper storage apparatus according to  claim 1 , wherein the friction means is provided at a plurality of positions at opposing sides of the lifting table, respectively.  
     
     
         6 . The paper storage apparatus according to  claim 1 , wherein the friction means is provided along opposing sides of the lifting table, respectively.
