Paper separation mechanism

Abstract

A paper separation mechanism, comprising a separation roller assembly having a separation roller, a torque limiter connected to the separation roller, and a separation gear arranged between the separation roller and the torque limiter; a transmission gear assembly having a first transmission gear which is able to mesh or separate with the separation gear, a second transmission gear meshed with the first transmission gear, and a connecting part connected the first transmission gear and the second transmission gear; and a motor connected to the transmission gear assembly for applying forward or reverse torque; wherein when the motor is applying the forward torque, the connecting part rotates forward to mesh the first transmission gear with the separation gear; and when the motor is applying the reverse torque, the connecting part rotates reverse to separate the first transmission gear with the separation gear.

What is claimed is: 
     
         1 . A paper separation mechanism, comprising:
 a separation roller assembly having a separation roller, a torque limiter connected to the separation roller and a separation gear arranged between the separation roller and the torque limiter;   a transmission gear assembly having a first transmission gear which is switched to mesh to the separation gear or switched to separate from the separation gear, a second transmission gear which meshes to the first transmission gear and a connecting part which connects the first transmission gear and the second transmission gear; and   a motor connected to the transmission gear assembly for applying a torque in a forward or reverse direction to the transmission gear assembly;   wherein when the motor is applying the torque in the forward direction, the connecting part rotates forward to mesh the first transmission gear with the separation gear;   wherein when the motor is applying the torque in the reverse direction, the connecting part rotates reverse to separate the first transmission gear with the separation gear.   
     
     
         2 . The paper separation mechanism as claimed in  claim 1 , wherein the transmission gear assembly has the first transmission gear which meshes with the separation gear to drive the separation gear, the second transmission gear which meshes with the first transmission gear, a third transmission gear which meshes with the second transmission gear, a fourth transmission gear which meshes with the third transmission gear, a fifth transmission gear which meshes with the fourth transmission gear and the motor, and the connecting part connects the first transmission gear and the second transmission gear.
