Claims

[Scope of utility model registration request]

(1) A feed roller that can rotate in the paper feeding direction and the paper path is sandwiched in pressure contact with the feed roller, and a constant torque is applied from the separation roller drive unit in the counter-feeding direction via the drive transmission member and the torque limiter to correct the feed roller. It has separate rollers that can rotate in either direction, and feeds the paper sheets one by one toward the registration rollers, and from the time the leading edge of the paper approaches the registration rollers, the paper buckling process is performed by excessively feeding the feed rollers. In the friction separation roller paper feeding device where the separate roller drive force is cut off until the registration roller starts driving at a predetermined timing, drive is transmitted between the separate roller drive section and the separate rollers. A friction separation roller paper feeding device characterized by comprising means for removing backlash of members.

(2) The friction separation roller paper feeding device according to claim 1, wherein the backlash removing means is an elastic member whose deformation amount is regulated.
