ABSTRACT:
An apparatus for identifying a paper currency. Before the front end of the currency is detected by optical sensors, the output signal (DATA1) from the optical sensors is stored in a first storage device. When the rear end of the currency subsequently passes across the sensors and the currency is no longer detected by the sensors, the output signal (DATA3) from the sensors is stored in a second storage device. If any currency-withdrawing device such as cord or tape is not attached to the currency, the DATA1 is equal to the DATA3 because these two kinds of data indicate the state in which nothing is present in the currency conveyance passageway. If such a currency-withdrawing device is attached to the currency, light from light-emitting devices is blocked or reflected by the cord or tape, thus varying the DATA3. However, the DATA1 is not affected. As a result, the DATA1 becomes unequal to the DATA3. In this way, attachment of the withdrawing device to the currency can be detected according to the results of detection made by the optical sensors, i.e., DATA1 and DATA3.
