Optical marking reading machine information acquisition processing and paper feeding control circuit

The utility model provides an optical marking reading machine information acquisition processing and paper feeding control circuit, which comprises a DSP processor, a memory, a USB2.0 protocol controller, an RS232 interface circuit, a voltage converter, a motor driver and a photoelectric coupler. The optical marking reading machine information acquisition processing and paper feeding control circuit is characterized in that the memory, the USB2.0 protocol controller, the RS232 interface circuit, the voltage converter and the photoelectric coupler are connected with the DSP processor, and the motor driver is connected with the photoelectric coupler. The DSP processor utilizes an integrated circuit TMS320F28335 or TMS320F28235. The optical marking reading machine information acquisition processing and paper feeding control circuit is simple in structure and stable in property, and reduces manufacturing cost of an optical marking reading machine.
