DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention will be described below with reference to drawings. Meanwhile, the following embodiments are examples of embodiments of the invention, and do not limit the scope of the invention.

First Embodiment

A first embodiment of the invention will be described first.

FIG. 1 is a front view illustrating the configuration of a banknote handling machine according to a first embodiment of the invention.

The banknote handling machine according to the first embodiment of the invention includes a taking-in unit 101, a transport state detection unit 102, a transport unit 103, a recognition unit 104, a first stacking unit, a second stacking unit, a third stacking unit, a designation unit 108 and a display unit 109.

The taking-in unit 101 takes in banknotes one by one from placed batches of banknotes. The taking-in unit 101 operates according to a control unit 110 to be described below.

The transport state detection unit 102 is a sensor that detects the transport state of the banknote taken in by the taking-in unit 101. When detecting the transport abnormality, the transport state detection unit 102 sends an abnormal transport signal to the control unit 110 to be described below. For example, the transport state detection unit 102 sends an abnormal transport signal to the control unit 110 in a state (skewed state) where a banknote is obliquely taken in by the taking-in unit 101, a state (chained state) where a plurality of banknotes are taken in without predetermined intervals, and a state (double-fed state) where a plurality of banknotes are taken in while overlapping.

The transport unit 103 is a transport mechanism for transporting the banknote, which is taken in by the taking-in unit 101, to the first stacking unit, the second stacking unit, or the third stacking unit. The transport unit 103 has the shape of a horizontal U-shaped transport path in FIG. 1, and is formed of a mechanism including a diverter that includes a plurality of transport belts, transport rollers, and diverter claws. The transport unit 103 operates according to the control unit 110 to be described below.

The recognition unit 104 is a sensor for recognizing the kind of the banknote (denomination, authenticity, fitness of the banknote) that is transported by the transport unit 103. When recognizing the kind of the banknote, the recognition unit 104 sends a recognition signal, which represents the result of the recognition, to the control unit 110 to be described below. Meanwhile, the recognition unit 104 has been provided on the rear side of the transport state detection unit 102. However, the recognition unit 104 may be provided on the front side of the transport state detection unit 102 or may be formed integrally with the transport state detection unit 102.

After that, the control unit 110 controls the display unit 109 so as to display a pattern image according to any image data of the pattern data 111B and 111C that is read in S302 (S303).

Sequentially, the control unit 110 controls the taking-in unit 101 to take in the placed banknotes one by one (S304).

After that, the control unit 110 performs the following determination according to an abnormal transport signal sent from the transport state detection unit 102 or a recognition signal sent from the recognition unit 104 (S305).

The control unit 110 activates any program module of the pattern data 111B and 111C that are read in S302, and performs a transport control to be described below (S306).

S304 to S306 are repeatedly performed until all of the banknotes placed in the taking-in unit 101 are transported (NO in S307). If all of the banknotes placed in the taking-in unit 101 are transported (YES in S307), the banknote stack handling according to the embodiment of the invention is completed.

FIG. 4 is a flowchart illustrating a handling procedure of the control unit 110 in the determination according to the first embodiment of the invention..

First, if an abnormal transport signal is sent from the transport state detection unit 102 (YES in S401), the control unit 110 determines an abnormally transported banknote as a determination result (S402).

Meanwhile, if an abnormal transport signal is not sent from the transport state detection unit 102 (NO in S401), the control unit 110 receives a recognition signal sent from the recognition unit 104 (S403).

After that, the control unit 110 performs fitness-unfitness determination (S404) for determining whether the shape of the banknote has abnormality, denomination determination (S405) for determining the denomination of the banknote, and authentication (S406) for determining whether the banknote is a genuine note, according to the recognition signal that is received in S403.

If the banknote is determined as a genuine note in S406 (YES in S407) and the denomination of the banknote is determined in S405 (YES in S408), the control unit 101 determines a specific normal banknote as a determination result (S409).

If the banknote is determined as a genuine note in S406 and the denomination of the banknote is not determined in S405 (NO in S408), the control unit 101 determines a non-specific banknote as a determination result (S410).

In contrast, if the banknote is not determined as a genuine note in S406 (NO in S407), the control unit 101 determines an abnormal banknote as a determination result (S411).

In S405, the control unit 110 may determine a banknote of one previously designated denomination as a specific banknote, and may determine a banknote of any of a plurality of previously designated denominations as a specific banknote.
