Media pick-up device of media dispenser

Abstract

The present invention discloses a media pick-up device of a media dispenser including a plurality of conveying rollers rotated by a driving force of a driving means, for conveying media, first separating rollers arranged with predetermined overlaps to the conveying rollers, for separating the media one by one, and second separating rollers arranged to face the conveying rollers with predetermined gaps, for generating a frictional force to the media. The media pick-up device of the media dispenser can accurately separate the media one by one regardless of variations of stiffness of the media.

1 . A media pick-up device of a media dispenser, comprising: 
 a plurality of conveying rollers rotated by a driving force of a driving means, for conveying media;    first separating rollers mounted on a shaft and arranged with overlaps to the conveying rollers, for separating the media one by one; and    second separating rollers mounted on the shaft and selectively operated dependent on media.    
   
   
       2 . The media pick-up device of  claim 1 , wherein the second separating rollers is arranged to face to an outer periphery of the conveying rollers with gaps between the separating rollers and the conveying rollers.  
   
   
       3 . The media pick-up device of  claim 1 , wherein a torsion spring for providing an elastic force to push the first and second separating rollers to the conveying rollers is installed on the shaft to which the first and second separating rollers are fixed.  
   
   
       4 . The media pick-up device of  claim 1 , wherein both the first and second separating rollers are rotated in an opposite direction to the conveying rollers.  
   
   
       5 . A media pick-up device of a media dispenser, comprising: 
 a plurality of conveying rollers rotated by a driving force of a driving means, for conveying media;    first separating rollers arranged with overlaps to the conveying rollers, for separating a first media; and    second separating rollers arranged to face an outer of the conveying rollers with a gap between the separating rollers and the conveying rollers, for generating a frictional force to separate a second media which is of lower stiffness than the first media.    
   
   
       6 . The media pick-up device of  claim 5 , wherein both the first and second separating rollers are mounted on a same shaft.  
   
   
       7 . The media pick-up device of  claim 5 , wherein both the first and second separating rollers are in a stationary state.  
   
   
       8 . The media pick-up device of  claim 5 , wherein both the first and second separating rollers are rotated in an opposite direction to the conveying rollers.
