Paper taking out device

Abstract

A paper taking out device includes a rubber roller which rotates in contact with a paper medium to take out the paper medium. The rubber roller is formed of a rubber material negatively electrified by sliding with the paper medium.

1 . A paper taking out device, comprising a rubber roller which rotates in contact with paper, thereby taking out the paper, wherein the rubber roller is formed of a rubber material negatively electrified by sliding with the paper.  
   
   
       2 . The paper taking out device according to  claim 1 , wherein the rubber roller is negatively positioned in triboelectric series order with respect to the paper.  
   
   
       3 . The paper taking out device according to  claim 1 , wherein the rubber roller has electric conductivity at which no corona electric discharge is generated.  
   
   
       4 . The paper taking out device according to  claim 1 , comprising a powdered paper removing roller which rotates in contact with the rubber roller and is positively electrified.  
   
   
       5 . The paper taking out device according to  claim 4 , wherein the powdered paper removing roller is positively positioned in triboelectric series order with respect to the rubber roller.  
   
   
       6 . The paper taking out device according to  claim 4 , wherein the powdered paper removing roller is formed of an elastic material.  
   
   
       7 . The paper taking out device according to  claim 4 , comprising an electrification control member brought into contact with the powdered paper removing roller to negatively electrify the rubber roller and to positively electrify the powdered paper removing roller.  
   
   
       8 . A paper taking out device comprising: 
 a rubber roller which rotates in contact with paper, thereby taking out the paper; and    an electrification device brought into contact with the rubber roller to negatively electrify the rubber roller.    
   
   
       9 . The paper taking out device according to  claim 8 , wherein the electrification device is formed of a material positively positioned in triboelectric series order with respect to the rubber roller, and is rotated in contact with the rubber roller.  
   
   
       10 . The paper taking out device according to  claim 8 , wherein the electrification device is formed of a roller section and an electrically conductive brush spirally provided on an outer peripheral face of this roller section and brought into contact with the rubber roller, and is rotated together with rotation of the rubber roller.  
   
   
       11 . The paper taking out device according to  claim 8 , wherein the electrification device is made of an electrically conductive member applied with high voltage electricity.
