<p><P>PROBLEM TO BE SOLVED: To provide a paper feeding device capable of restricting the occurrence of paper feeding error by adjusting upward energizing force of a push-up plate in response to operation of a paper feeding roller. <P>SOLUTION: A crank means (disk) 16 is fixed to a driving shaft 7a of the paper feeding roller 7 for cooperative rotation, and a tensile spring 17 is stretched between the crank means 16 and a rocking side of the push-up plate 9. Lock position of the tensile spring 17 in relation to the crank means 16 is set so that the tensile spring 17 has the maximum tensile force and energizes the push-up plate 9 upward when delivering/separating a paper sheet with rotation of the paper feeding roller 7 and so that a front end of a paper sheet bundle P is strongly pushed to the paper feeding roller 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
