Claims

[Scope of utility model registration request]

A pickup roller that rotates in the paper feeding direction at a predetermined timing, a feed roller that is downstream of the pickup roller and rotates in the same direction in synchronization with the pickup roller, and a feed roller that pinches the paper path and presses against it and reverse rotation from the drive shaft. Two reverse rollers are provided on each axis extending perpendicularly to the paper feeding direction, and the reverse gear and torque limiter are provided with two reverse rollers to which a constant torque is applied in the opposite direction to the paper feeding direction via a gear and a torque limiter. and the reverse roller are coaxially provided on a single shaft, and the shaft is rotatably supported near the tips of a pair of pressure levers that are biased to rotate in the direction of pressing the reverse roller against the feed roller. In the paper feeding device, the reverse roller shaft is fitted into a notch that opens toward the feed balancer shaft near the tip of the pressure lever, and is rotatably supported at the bottom of the notch. A paper feeding device characterized in that the roller, torque limiter, and reverse gear are detachably attached to the pressure lever as a unit integrated with the reverse roller shaft.
