Abstract: A paper feeding mechanism includes a mechanical frame, a drive assembly mounted to the mechanical frame, an input tray, a pickup assembly driven by the drive assembly, an elevating assembly and a control assembly. The elevating assembly mounted to the mechanical frame and pivoted to a bottom of the rear end of input tray includes a drive shaft, a gear assembly and an elastic element. The rotating shaft defines two cam parts projecting beyond the rotating shaft. The rotating shaft is capable of rotating to make the cam parts press downward on or break away from the input tray so as to drive the input tray to swing downward or swing upward under an elastic push action of the elastic element. The control assembly includes a control system and a paper sensor controlled by the control system for detecting whether there is any paper on the input tray.
