  • Paper transferring mechanism utilizing a swing gear and controlling method thereof
    Patent number: 6942215
    Abstract: The paper transferring mechanism includes a drive gear coaxially coupled with a rotation shaft of a motor, a pick-up gear coupled with a shaft of a pick-up roller to separately feed the paper sheets, and a feed gear coupled with a shaft of a feed roller to outwardly transfer the paper sheets. The paper transferring mechanism also includes a discharge gear coupled with a shaft of a discharge roller to outwardly discharge the paper sheets, and a swing gear having one end connected to the drive gear and the other end selectively connected to one of the pick-up gear and the feed gear. The pick-up gear is rotated when the motor is rotated in a first direction, the feed gear is rotated when the motor is rotated in a second direction, and the discharge gear is rotated constantly in one direction regardless of the rotation direction of the motor.
