Abstract: If the number of returned bills is two or more, the returned bills are identified as abnormally returned bills by an abnormally returned bill detector, and predetermined abnormal-state processing is accomplished by performing control operations using an abnormality processor. If a bill has jammed in the bill conveying channel, information concerning the direction in which the bill has jammed is stored in the bill jamming direction memory unit of the control unit, and, as a result of control operations performed by the bill reverse-direction conveyance control unit of the control unit, the bill is conveyed in the direction opposite to the bill jamming direction stored in the bill jamming direction memory unit when the bill jammed in the bill conveying channel is to be removed.

Abstract: A paper money processor using a single motor in which, when the motor is forwardly driven, a power transmission section transmits a rotational force of the motor only to a paper money transporter section to convey an inserted paper money into the interior of a processor body and when the motor is reversely driven, the power transmission section transmits the rotational force of the motor to both of the paper money transporter section and a pushing section to drive the both so as to return the paper money back to a paper money insert slot, and when a repayment demand occurs, a control section permits the reverse rotation of the motor only if the paper money is located at a returnable position.
