Drive device for paper feeder

A drive device for paper feeder in a facsimiles, comprising:

• a drive motor for generating a rotating force;
• main transmission gears for rotating both a document separation roller and a guide roller by transmitting the rotating force of the motor to said rollers during initial rotation of the motor, and for rotating a register roller by transmitting the rotating force of the motor to said register roller during reverse rotation of the motor;
• said register roller, said document separation roller and said guide roller rotatably connected to said main transmission gears;
• and
• first auxiliary transmission means for transmitting the rotating force of said register roller to said document separation roller during the reverse rotation of the motor,
• wherein the rotating force of the motor is transmitted to the document separation roller and the guide roller during the initial rotation of the motor without being transmitted to the register roller, while the rotating force of the motor is transmitted to the register roller and the document separation roller during the reverse rotation of the motor.
