<p>PURPOSE:To prevent a paper jam from occurring as well as to make the promotion of high speediness attainable by changing paper feeding time and speed to the optional time and speed according to a paper feeding interval, and constituting it to compensate the paper feeding interval. CONSTITUTION:A paper feeding interval is measured by a table central processing unit 9 at each time when a rear end of a preceding sheet of paper 12 run past a final table feed roller 17 by a table sensor 15 and when a tip of a succeeding sheet of paper is reached to the table sensor 15. The paper 12 passed through the table feed roller 17 of an LCIT (large quantity paper feed tray) 5 is fed at constant speed by a resist roller 16 of a body 1. Then, whether the paper feeding interval is more than 40mm, by way of example, or not is judged by the central processing unit 9, and if YES is the case, the paper feeding interval is barrowed by stepping up rotation speed of an LCIT motor 10 as far as, for example, 50%, then if a specified period of time (for example 0.4sec) has elapsed, the motor 10 is put back to the normal speed. Thus, the paper feeding interval is narrowed for compensation.</p> |
