Abstract
Disclosed is an automatic teller machine (ATM) including a clutch device for selectively supplying power to a pick-up roller for extracting banknotes from a banknote storage cassette located within the ATM. The clutch device includes a driving gear rotatably mounted to the frame for receiving the rotational driving force from the drive motor to rotate the plurality of driving rollers, an idle gear engaged with the driving gear for rotating in response the rotational movement of the driving gear, a pick-up roller gear fixedly mounted on a rotating shaft of the pick-up roller and engaged with the idle gear for rotating the pick-up roller and, and a motor control means adapted to allow the idle gear to be engaged with or disengaged from the pick-up roller. Therefore, since the transmission of a rotational driving force to the pick-up roller is performed by means of gears, not friction plates, the control performance of power transmission of the clutch device is uniformly maintained even after use for extended period of time. Also, the pick-up roller can rapidly respond to the power transmission of the clutch device by employing an actuator for allowing the gears to be selectively engaged with or disengaged from each other. Further, extra rotation of the pick-up roller due to rotational inertia thereof is prevented by employing stopping means for exclusively controlling the overall operation of the pick-up roller, thus allowing the pick-up roller to perform the correct extraction of banknotes.
