<p>PURPOSE:To securely prevent duplicate feeding of the paper sheets by a duplicate feeding preventing mechanism. CONSTITUTION:A first paper sensor 50 to detect the biting of the paper sheet P between rollers is arranged to the side of the paper feeding direction of a paper feeding roller 11 in a duplicate feeding preventing mechanism 10 where the paper feeding roller 11 is pressed against a duplicate feeding preventing roller 12. After the paper sheet P is carried by the paper sheet roller 11, and when the first paper sensor detects that a paper sheet is bitten between the roller 11 and the roller 12, the paper feeding roller 11 and the duplicate feeding preventing roller 12 are activated and the paper sheet is carried.</p> |
