Abstract

PURPOSE: To make it possible to stably feed papers without causing overlap feeding, misfeeding and the like by detecting the rotational angles of a driving shaft and a feed roller, and controlling a paper pressing force by this signal.
CONSTITUTION: When a feed roller 3 is rotated and a paper is delivered, since there is a relationship between static friction coefficient is greater thab dynamic friction coefficient, a paper holding force F' becomes small, a driving torque transmitted to the feed roller 3 becomes small, a leaf spring 17 is restored at a certain degree, the difference in the rotational angle between the driving shaft 12 and the feed roller 3 is reduced, the difference in the rotational angle between discs 20 and 21 becomes small, and the value of the difference is fed back to a servo motor 9 and the keep pressure N is controlled so that the paper feed force F becomes constant. As described above, every time the driving torque of the feed roller 3 varies, the tension pressure N is controlled so that the paper feed force F is operated to be constant.
