Abstract
A paper pickup mechanism mounted in a feeder includes several driving gears, connecting rods, a pickup roller and a twist restricting gear. By means of the twist restricting gear, the paper pickup mechanism provides an equal pickup force under different paper loads. Furthermore, the operational precision of the pickup roller is improved via relative motion with the twist restricting gear.
