Automatic teller machine and method to control transfer of paper thereof

PURPOSE: An automatic teller machine and their paper medium transfer controlling method are provided to not have a separated storage, and then the fetch process of the rejected paper medium is simplified than before. CONSTITUTION: A medium transfer part(125) transfers a paper medium provided from a media storage storing paper mediums. When the paper medium is transferred along to the medium transfer part, the normally detected paper medium is transferred to a media carrier. A reject medium transfer part(160) is connected to the medium transfer part. Since the paper medium is transferred to the medium transfer part, an abnormal state is detected, the rejected paper medium is selectively transferred. A direction changing part(180) is arranged in the connection part of the medium transfer part, the media carrier, and the reject medium transfer part. And the direction changing part selectively switches the progressive direction of the paper medium, so that the paper medium transferred through the medium transfer part is transferred to the media carrier or the reject medium transfer part.
