Printer

Abstract

A printer which reduces feeding failure that occurs when a roller is pressed against a sheet of paper by power of a driving source includes: a rotating member which rotates around a first axis; a connecting member which connects with the rotating member; a roller which is disposed in the connecting member and rotates around a second axis to transfer a medium; and a support member disposed across from the roller, wherein the roller applies a force to the medium based on rotation of the rotating member, and the medium is transferred between the roller and the support member.

1 . A printer comprising:
 a rotating member which rotates around a first axis;   a connecting member which connects with the rotating member;   a roller which is disposed in the connecting member and rotates around a second axis to transfer a medium; and   a support member disposed across from the roller,   wherein the roller applies a force to the medium based on rotation of the rotating member, and   the medium is transferred between the roller and the support member.   
     
     
         2 . The printer according to  claim 1 ,
 wherein the support member includes a frictional member and an elastic member.   
     
     
         3 . The printer according to  claim 2 ,
 wherein when the medium includes a first sheet of paper and a second sheet of paper, a frictional force between the frictional member and an underside of the second sheet of paper is (i) larger than a frictional force between an underside of the first sheet of paper and a topside of the second sheet of paper and (ii) smaller than a frictional force between the roller and a topside of the first sheet of paper.   
     
     
         4 . The printer according to  claim 2 ,
 wherein the elastic member is smaller than the frictional member in hardness value.   
     
     
         5 . The printer according to  claim 2 ,
 wherein the elastic member is a spring.   
     
     
         6 . The printer according to  claim 2 ,
 wherein the elastic member has an end connected to a loading surface on which the medium is loaded, and   the elastic member has an other end which moves downward when the frictional member and the elastic member are pressed by the roller via the medium.   
     
     
         7 . The printer according to  claim 1 , further comprising
 a flywheel connected to a rotation shaft of a driving source which rotates the rotating member.   
     
     
         8 . The printer according to  claim 7 ,
 wherein the driving source is disposed between the flywheel and the rotating member.   
     
     
         9 . The printer according to  claim 2 ,
 wherein the roller is larger than the frictional member in width, and   the roller has an outer circumferential surface having a circumferentially extending dip across from the frictional member.
