摘要：
A paper transmitting mechanism mounted on the transmitting path which includes a driving wheel, a driving system drives the driving wheel, a pressure wheel, a pressure wheel adjusting unit, and a paper sensor settled upstream to the driving wheel and pressure wheel. The pressure wheel adjusting unit includes an elastomeric unit; one end of the elastomeric unit is connected to the axle of the pressure wheel, and the other end is connected to a linear driving device. When the paper sensor detects the paper is going to enter or leave the driving wheel, the paper sensor will send a signal for adjusting the clamping force between the driving wheel and the pressure wheel to make the clamping force and the friction between the driving wheel and the pressure wheel adjustable according to the position of the paper, so as to avoid the paper slipping or vibrating during transmitting.
