Proposed are a highly reliable automatic transaction device and a control method thereof. Specifically provided is an automatic transaction device, and a control method thereof, including a main body control unit which generates first withdraw transaction data including amount information as information related to an amount in a withdraw transaction and a withdraw command for instructing a withdraw of a paper currency based on the first withdraw transaction data, a paper currency processing unit which receives the withdraw command and pays out the paper currency, and a first device which is a device that is different from the paper currency processing unit and which determines a feasibility of a withdraw based on the first withdraw transaction data sent from the main body control unit. When the first device determines that the withdraw is possible, the first device generates withdraw credit information with security that is higher than the withdraw command based on the first withdraw transaction data. The paper currency processing unit receives the withdraw credit information and the withdraw command, additionally determines the feasibility of the withdraw based on the withdraw credit information and the withdraw command, and pays out the paper currency when the withdraw is possible.

Automatic transaction device and control method thereof

A frequency synthesizer comprises a voltage controlled generator (11) for generating an output signal of a desired frequency in response to a control signal and a reference signal generator (13) for generating a reference frequency signal. The output signal is sampled (21) by the reference frequency to produce a sampled signal. The reference frequency signal is frequency divided (22) by a division factor determined by the desired frequency and the reference frequency. The sampled signal and the divided signal are compared (15) in phase and frequency and the control signal is produced depending on the phase difference between the two signals. For the division factor, two different values are determined by the desired frequency and the reference signal and one of the two values is selected according to a selection pattern determined by the reference frequency and the desired frequency. A control circuit (41) calculates the two values and a multistage frequency divider (42) generates the selection pattern signal under control of the control circuit (41).
