The money handling machine receives an instruction to dispense money, performs dispensing money in which the amount of money to be dispensed out of the money stored in the denomination-specific storing portion is only transported to the dispensing portion and performs dispensing limitation processing in which the transport of money determined not to be allowed to be dispensed is prevented from being completed. The dispensing processing includes the first step of starting the transport of the amount of money corresponding to the instruction to dispense money and the second step of transporting, after completion of the first step, money from the denomination-specific storing portion to the dispensing portion such that a shortage of dispensed money produced by performing the dispensing limitation processing is replenished. In this way, it is possible not only to prevent money that is not allowed to be dispensed from being dispensed and to accurately dispense money corresponding to the instruction to dispense money but also to more quickly perform the dispensing processing. | 07-22-2010 |

20130001039 | BANKNOTE HANDLING APPARATUS AND BANKNOTE MANAGING METHOD - A banknote handling apparatus stores a code list in which codes of banknotes stored in a storage unit are arranged in order in which the banknotes are stored. The banknote handling apparatus reads the codes when the banknotes are sequentially fed from the storage unit, and checks a target group of the codes of N successive banknotes including the last fed banknote (N is a natural number not less than 2) against the code list. When the target group and a reference group of the codes of N successive banknotes in the code list match each other, the banknotes remaining in the storage unit after the feeding of the banknotes are identified by regarding one of the codes of the reference group in the code list as a boundary. | 01-03-2013 |
20130001040 | BANKNOTE HANDLING APPARATUS - A banknote handling apparatus is operable in a code management mode in which banknotes stored in a storage unit are managed based on codes of the banknotes read by a recognition unit, and in a count management mode in which the banknotes stored in the storage unit are managed by counting the number of the banknotes to be stored in the storage unit. The banknote handling apparatus is switchable between the code management mode and the count management mode. | 01-03-2013 |
