Abstract
A paper feeding device comprises an upper frame, a pickup roller assembly connected to the upper frame and a lower frame. The pickup roller assembly includes a roller frame, a separating roller, a pickup roller, and a belt sleeved on both the separating roller and the pickup roller. The separating roller and the pickup roller are connected to the roller frame. The belt impels the separating roller and the pickup roller to press against the roller frame. When the separating roller rotates, the friction created between the separating roller and the roller frame and the friction created between the pickup roller and the roller frame drives the pickup roller assembly to rotate, then the paper is fed into the paper feeding device. The structure of the paper feeding device is simple and the cost is lower than the conventional one, moreover, it is convenient to assemble.
