Abstract:
1. A paper pickup mechanism located on one side of a feeding paper tray, comprising: a driver gear for receiving rotational power transmitted from a driving power source having a pivoted axle; an idler gear driven by the driver gear and having a rotation axis connecting to a rotation axis of the driver gear through a first linkage bar; a swing arm having a pivoted end and a swing end, the swing arm being rotatable around the pivoted end; a pickup gear located on the swing end of the swing arm to engage with the idler gear when the idler gear is driven by the driver gear; and a pickup roller being coaxial with the pickup gear and driven by the driver gear to rotate in a paper feeding direction to generate a torque to exert a force on a paper located on a top of the feeding paper tray; a rotation axis of the pickup gear and the rotation axis of the idler gear being linked through a second linkage bar for engaging the pickup gear and the idler gear with each other; and the first linkage bar extending from the rotation axis of the driver gear to the rotation axis of the idler gear and the second linkage bar extending from the rotation axis of the pickup gear to the rotation axis of the idler gear such that the rotation axis of the driver gear is located downstream of the rotation axis of the idler gear and the pivoted end of the swing arm is located upstream of the rotation axis of the idler gear.
