Title: Money handling system, money handling machine, and money handling method

Description:
TECHNICAL FIELD 
     The present invention relates to a money handling system that handles money such as banknotes and coins, a money handling machine and a money change machine in the money handling system, and a money handling method performed by the money handling system. 
     BACKGROUND ART 
     In stores of commercial facilities such as supermarkets and convenience stores, a money change machine is installed together with a POS register at a settlement place in a front office region where store shelves are arranged, and a money depositing/dispensing machine such as a cashier machine is installed in a back office region which customers are not allowed to enter. The money change machine installed at the settlement place in the front office region can deposit money delivered as proceeds from sales for a commodity from a customer to a clerk, and can dispense money as change. Furthermore, the money depositing/dispensing machine such as a cashier machine installed in the back office region deposits money, as proceeds from sales, collected from the money change machine, and dispenses money as change fund with which the money change machine is to be replenished. As such a money handling system in which a money change machine and a money depositing/dispensing machine are combined with each other, for example, the money handling system disclosed in Japanese Laid-Open Patent Publication No. 2015-207311 (JP2015-207311A) and the like is conventionally known. 
     In the conventional money handling system disclosed in Japanese Laid-Open Patent Publication No. 2015-207311 and the like, banknotes are delivered between the money change machine and the money depositing/dispensing machine by using a storage cassette capable of storing banknotes and feeding out the stored banknotes. More specifically, the storage cassette is detachably mounted to each of the money change machine and the money depositing/dispensing machine, and only when the storage cassette is mounted to the money change machine or the money depositing/dispensing machine, banknotes can be fed out from the storage cassette. This can prevent a malicious operator from taking out a part of banknotes when the banknotes are delivered between the money change machine and the money depositing/dispensing machine, whereby the banknote handling system can more efficiently prevent theft. In such a money handling system, when banknotes as proceeds from sales are collected from the money change machine and deposited in the money depositing/dispensing machine, an empty storage cassette is firstly mounted to the money change machine, banknotes in the money change machine are sent to the storage cassette, the storage cassette is thereafter dismounted from the money change machine, and the storage cassette is conveyed to the money depositing/dispensing machine. Thereafter, when the storage cassette is mounted to the money depositing/dispensing machine, the banknotes are fed out from the storage cassette and stored into the money depositing/dispensing machine. Meanwhile, when banknotes as change fund are dispensed from the money depositing/dispensing machine, and the money change machine is replenished with the change fund, an empty storage cassette is firstly mounted to the money depositing/dispensing machine, banknotes in the money depositing/dispensing machine are sent to the storage cassette, the storage cassette is thereafter dismounted from the money depositing/dispensing machine, and the storage cassette is conveyed to the money change machine. Thereafter, when the storage cassette is mounted to the money change machine, the banknotes are fed out from the storage cassette and stored into the money change machine.

Thereafter, the clerk in charge of the register mounts the storage cassette  40  to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 . Thus, banknotes, as proceeds from sales, which are stored in the storage cassette  40  are fed out from the storage cassette  40 , sent into the housing of the banknote handling device  32 , and stored in the storage/feeding unit  32   a  of the banknote handling device  32 . The clerk in charge of the register takes out the coins as proceeds from sales, from the storage case, and performs depositing of the taken coins in the coin handling device  34 . Thus, the coins, as proceeds from sales, collected from the coin handling device  24  are stored in the storage/feeding unit  34   a  of the coin handling device  34 . The clerk in charge of the register takes out the mediums (for example, vouchers and the like) other than banknotes and coins, from the storage case, with her/his hands, and stores the taken mediums in the coin roll storing device  36 . In the present embodiment, when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , information stored in the storage medium  42  of the storage cassette  40  is read by the reader writer  32   d . Thus, for example, information (specifically, the number of banknotes and the number of coins for each denomination) on banknotes and coins which have been collected from the banknote handling device  22  and the coin handling device  24  and stored in the storage cassette  40  is managed by the controller  38  of the money depositing/dispensing machine  30 . 
     Next, an operation (that is, operation indicated by reference numeral (b) in  FIG. 1 ) performed by the money handling system  10  during the replenishing process will be described. Before the business hours of the store, a clerk in charge of a register performs dispensing of coins and banknotes (that is, banknotes and coins as change fund) to be stored as change in the money change machine  20 , from the money depositing/dispensing machine  30 . Specifically, the clerk in charge of the register mounts the empty storage cassette  40  to the cassette mounting unit  32   c  of the banknote handling device  32 , whereby banknotes as change fund are fed out from the storage/feeding unit  32   a  of the banknote handling device  32  and stored in the storage cassette  40 . The clerk in charge of the register causes the coin handling device  34  to dispense coins stored in the storage/feeding unit  34   a . The clerk in charge of the register stores the coins as change fund dispensed from the coin handling device  34 , in the storage case (not shown), with her/his hands. The clerk in charge of the register takes out coin rolls stored in the coin roll storing device  36 , with her/his hands, and stores the taken coin rolls in the storage case with her/his hands. When banknotes and coins as change fund are dispensed from the banknote handling device  32 , the coin handling device  34 , and the like, information (specifically, the number of the banknotes and the number of the coins for each denomination) on banknotes and coins dispensed from the banknote handling device  32  and the coin handling device  34  are written into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . The identification number of the settlement place at which the money change machine  20  to be replenished with the banknotes and the coins dispensed from the banknote handling device  32  and the coin handling device  34  is installed, and the identification number of the clerk in charge of the register who has performed the dispensing may be written into the storage medium  42  of the storage cassette  40  by the reader writer  32   d.    
     When the banknotes and coins as change fund have been stored in the storage cassette  40  and the storage case, the clerk in charge of the register conveys the storage cassette  40  and the storage case from the back office region  14  to the front office region  12 . Thereafter, the clerk in charge of the register mounts the storage cassette  40  to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 . Thus, the banknotes as change fund stored in the storage cassette  40  are fed out from the storage cassette  40 , sent into the housing of the banknote handling device  22 , and stored in the storage/feeding unit  22   a  of the banknote handling device  22 . The clerk in charge of the register takes out coins as change fund from the storage case, and performs depositing of the taken coins in the coin handling device  24 . Thus, the coins as change fund dispensed from the coin handling device  34  are stored in the storage/feeding unit  24   a  of the coin handling device  24 . The clerk in charge of the register takes out coin rolls as change fund, from the storage case, with her/his hands, and stores the taken coin rolls in the coin roll storing device  26 . In the present embodiment, when the storage cassette  40  has been mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , information stored in the storage medium  42  of the storage cassette  40  is read by the reader writer  22   d . Thus, for example, information (specifically, the number of banknotes and the number of coins for each denomination) on banknotes and coins as change fund which are dispensed from the banknote handling device  32  and the coin handling device  34  and stored in the storage cassette  40  is managed by the controller  28  of the money change machine  20 . 
     In the money handling system  10  according to the present embodiment, a spare storage cassette  40  (that is, the storage cassette  40  which does not correspond to any of the money change machines  20 ) is used in addition to the storage cassettes  40  used so as to correspond to the respective money change machines  20 . In a case where, when money is collected from each money change machine  20  and deposited in the money depositing/dispensing machine  30 , the storage/feeding unit  32   a  in the banknote handling device  32  of the money depositing/dispensing machine  30  is in a full state or a nearly full state and banknotes can no longer be stored in the storage/feeding unit  32   a , such a spare storage cassette  40  is used for storage so as to temporarily store banknotes stored in the storage/feeding unit  32   a . Such a technical matter will be described below in detail. 
     In the money handling system  10  according to the present embodiment, an entire collection process in which all the money is collected from the plurality of the money change machines  20 , and deposited in the money depositing/dispensing machine  30  may be periodically performed. In a case where, during such an entire collection process, the storage/feeding unit  32   a  in the banknote handling device  32  of the money depositing/dispensing machine  30  has been in a full state or a nearly full state and banknotes can no longer be stored in the storage/feeding unit  32   a , an operation of feeding out banknotes from the storage cassette  40  mounted to the cassette mounting unit  32   c  of the banknote handling device  32  and sending the banknotes to the storage/feeding unit  32   a  is stopped. Information indicating that the storage/feeding unit  32   a  is in a full state or a nearly full state is displayed on the operation/display unit  39   a  of the money depositing/dispensing machine  30 . A screen for prompting the operator to dismount the storage cassette  40  for collection, from the cassette mounting unit  32   c  of the banknote handling device  32 , and mount the spare storage cassette  40  to the cassette mounting unit  32   c  is displayed on the operation/display unit  39   a  of the money depositing/dispensing machine  30 . Thereafter, when the operator such as the clerk in charge of the register dismounts the storage cassette  40  for collection, from the cassette mounting unit  32   c  of the banknote handling device  32 , and mounts the empty spare storage cassette  40  to the cassette mounting unit  32   c , banknotes are fed out from the storage/feeding unit  32   a  and stored in the storage cassette  40 . As indicated by reference numeral (c) in  FIG. 1 , the operator dismounts the storage cassette  40  from the cassette mounting unit  32   c . Thus, the storage cassette  40  storing banknotes is retained in the back office region  14 . In such an operation, the storage/feeding unit  32   a  of the banknote handling device  32  can have an excess space and the entire collection process can be continuously performed. 
     In the money handling system  10  according to the present embodiment, while banknotes and coins as change fund with which each money change machine  20  is to be replenished are being dispensed from the money depositing/dispensing machine  30 , the storage/feeding unit  32   a  of the banknote handling device  32  may become empty. In such a case, the operator such as the clerk in charge of the register mounts the storage cassette  40 , for storage, which stores the banknotes and has been retained in the back office region  14 , to the cassette mounting unit  32   c  of the banknote handling device  32  as indicated by reference numeral (d) in  FIG. 1 . Thus, banknotes are fed out from the storage cassette  40  and sent to the storage/feeding unit  32   a , whereby the replenishing process of replenishing each money change machine  20  with money as the change fund can be continuously performed. 
     In the present embodiment, the usage determination unit  50  determines the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c , according to a storing state of banknotes in the storage/feeding unit  32   a . The usage of the storage cassette  40  which is determined by the usage determination unit  50  is written into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . Specifically, the usage of the storage cassette  40  includes collection, replenishment, and storage. The usages of the storage cassettes  40  used so as to correspond to the respective money change machines  20  are generally collection or replenishment. Meanwhile, the usage of the spare storage cassette  40  is generally storage. 
     More specifically, in the above-described collection process, in a case where the empty storage cassette  40  is mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , and the operator thereafter inputs an instruction for performing the collection process through the operation/display unit  29   a , the usage of the storage cassette  40  is written as collection into the storage medium  42  of the storage cassette  40  by the reader writer  22   d . In the banknote handling device  22 , banknotes as proceeds from sales are fed out from the storage/feeding unit  22   a , and the banknote having been fed out are stored in the storage cassette  40 . Thereafter, in a case where the storage cassette  40  is dismounted from the cassette mounting unit  22   c  and conveyed from the front office region  12  to the back office region  14 , and the storage cassette  40  is thereafter mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , when the information indicating that the usage of the storage cassette  40  is collection is read from the storage medium  42  of the storage cassette  40  by the reader writer  32   d , banknotes as proceeds from sales are sent from the storage cassette  40  to the storage/feeding unit  32   a  (see  FIG. 6 ). 
     In the above-described replenishing process, in a case where the empty storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , and the operator thereafter inputs an instruction for performing the replenishing process to the operation/display unit  39   a , the usage of the storage cassette  40  is written as replenishment into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . In the banknote handling device  32 , banknotes as change fund are fed out from the storage/feeding unit  32   a , and the banknotes having been fed out are stored in the storage cassette  40  (see  FIG. 6 ). Thereafter, in a case where the storage cassette  40  is dismounted from the cassette mounting unit  32   c  and conveyed from the back office region  14  to the front office region  12 , and the storage cassette  40  is thereafter mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , when information indicating that the usage of the storage cassette  40  is replenishment is read from the storage medium  42  of the storage cassette  40  by the reader writer  22   d , banknotes as change fund are sent from the storage cassette  40  to the storage/feeding unit  22   a.    
     In a case where the storage/feeding unit  32   a  in the banknote handling device  32  of the money depositing/dispensing machine  30  is in a full state or a nearly full state and banknotes can no longer be stored in the storage/feeding unit  32   a , when the empty storage cassette  40  is mounted to the cassette mounting unit  32   c , the usage determination unit  50  determines, as storage, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c . In this case, the usage of the storage cassette  40  is written as storage into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . After the usage of the storage cassette  40  is written as storage into the storage medium  42  of the storage cassette  40  by the reader writer  32   d , banknotes are fed out from the storage/feeding unit  32   a  in the banknote handling device  32 , and the banknotes having been fed out are stored in the storage cassette  40  (see  FIG. 6 ). Thus, the controller  38  performs control such that banknotes are sent from the storage/feeding unit  32   a  to the empty storage cassette  40  mounted to the cassette mounting unit  32   c  according to a storing state of banknotes in the storage/feeding unit  32   a . Thereafter, the replenishing process is performed by the money depositing/dispensing machine  30  and the storage/feeding unit  32   a  has an excess space. Thereafter, when the storage cassette  40 , for storage, which stores banknotes is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , information on the usage of the storage cassette  40  is read from the storage medium  42  of the storage cassette  40  by the reader writer  32   d . When the usage of the storage cassette  40  is read as storage by the reader writer  32   d , banknotes are fed out from the storage cassette  40 , and the banknotes having been fed out are stored in the storage/feeding unit  32   a  ( FIG. 6 ). 
     In the present embodiment, instead of collection and replenishment being separately set as the usage of the storage cassette  40 , replenishment collection may be set as the usage. An operation performed when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  in the case of the usage, of the storage cassette  40 , which is stored in the storage medium  42  of the storage cassette  40  being replenishment collection, will be described below. In a case where the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , and the usage of the storage cassette  40  which is read from the storage medium  42  of the storage cassette  40  by the reader writer  32   d  is replenishment collection, when banknotes are stored in the storage cassette  40 , the storage cassette  40  is considered to store banknotes collected from the banknote handling device  22  of the money change machine  20 , so that banknotes are fed out from the storage cassette  40  and sent to the storage/feeding unit  32   a . Meanwhile, in a case where the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , and the usage of the storage cassette  40  which is read from the storage medium  42  of the storage cassette  40  by the reader writer  32   d  is replenishment collection, when no banknotes are stored in the storage cassette  40 , the storage cassette  40  is considered to be used for replenishing the money change machine  20  with banknotes as change fund, so that banknotes are fed out from the storage/feeding unit  32   a  and sent to the storage cassette  40  (see  FIG. 6 ). 
     In the present embodiment, the spare storage cassette  40  (that is, the storage cassette  40  which does not correspond to any of the money change machines  20 ) may be used in the replenishing process for replenishing each of the money change machines  20  with money as change fund. Specifically, in a case where the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , when the operator makes an input indicating that the usage of the storage cassette  40  is replenishment by the spare through the operation/display unit  39   a , information indicating that the usage of the storage cassette  40  is replenishment by the spare is written into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . Information (specifically, information on, for example, the number of banknotes with which each banknote handling device  22  is to be replenished, for each denomination) on money as change fund with which each money change machine  20  is to be replenished is also written into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . Banknotes as change fund with which each money change machine  20  is to be replenished are fed out from the storage/feeding unit  32   a  and sent to the storage cassette  40 . Thereafter, as indicated by reference numeral (e) in  FIG. 7 , the storage cassette  40  which stores banknotes as change fund with which each money change machine  20  is to be replenished is conveyed from the back office region  14  to the front office region  12 , and mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of each money change machine  20 , and, thus, the storage/feeding unit  22   a  in the banknote handling device  22  of each money change machine  20  is replenished with banknotes as change fund from the storage cassette  40  More specifically, when the storage cassette  40  is mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , and information indicating that the usage of the storage cassette  40  is replenishment by the spare is read from the storage medium  42  of the storage cassette  40  by the reader writer  22   d , a predetermined number of banknotes are fed out from the storage cassette  40  based on the information, on money as change fund, which is read from the storage medium  42  by the reader writer  22   d , and sent to the storage/feeding unit  22   a.    
       FIG. 7  shows an operation of replenishing a plurality of the money change machines  20  with banknotes as change fund by using a single storage cassette  40  for replenishment by the spare. However, the money handling system  10  according to the present embodiment is not limited to such an aspect. In another example of the money handling system  10  according to the present embodiment, a single money change machine  20  may be replenished with banknotes as change fund from a single storage cassette  40  for replenishment by the spare. In this case, when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , information (specifically, information on, for example, the number of banknotes with which the one banknote handling device  22  is to be replenished, for each denomination) on money as change fund with which the one money change machine  20  is to be replenished is written into the storage medium  42  of the storage cassette  40  by the reader writer  32   d.    
     In the money handling system  10  according to the present embodiment, the storage cassette  40  (that is, the storage cassette  40  used for collection or replenishment) which is used for the corresponding money change machine  20  may be used also as the spare storage cassette  40 . That is, in a case where, when the storage cassette  40  of which the usage is stored as collection or replenishment in the storage medium  42  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , banknotes can no longer be stored in the storage/feeding unit  32   a  due to the storage/feeding unit  32   a  being in a full state or a nearly full state, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c  is changed from collection or replenishment to storage by the usage determination unit  50 . In this case, the usage of the storage cassette  40  is written as storage into the storage medium  42  of the storage cassette  40  by the reader writer  32   d . After the usage of the storage cassette  40  is written as storage into the storage medium  42  of the storage cassette  40  by the reader writer  32   d , banknotes are fed out from the storage/feeding unit  32   a  and sent to the storage cassette  40 . 
     In still another example of the money handling system  10  shown in  FIG. 1  to  FIG. 10 , when the empty storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , the usage determination unit  50  may determine, as storage, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c , regardless of a storing state of banknotes in the storage/feeding unit  32   a . In this case, in a case where the operator wants to perform the replenishing process, when the operator inputs an instruction for the replenishing process through the operation/display unit  39   a , the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c  is changed from storage to replenishment by the usage determination unit  50 . 
     In the money handling system  10  according to the present embodiment, when a large number of banknotes are to be collected from the money change machine  20 , a plurality of the storage cassettes  40  may be used in one transaction (in other words, collection process performed at one time). In this case, after the plurality of the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) in the money change machine  20  are conveyed to the money depositing/dispensing machine  30 , banknotes are stored into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) of the money depositing/dispensing machine  30  from the storage cassettes  40  one by one in the money depositing/dispensing machine  30 . In a conventional money handling system, since the money depositing/dispensing machine cannot obtain the number of the storage cassettes which are used in the collection process of collecting banknotes from the money change machine, the operator may forget to mount one or more of the plurality of the storage cassettes to the money depositing/dispensing machine. In this case, a problem may arise that an error in calculation occurs in the money depositing/dispensing machine. Meanwhile, in the present embodiment, the determination unit  51  determines whether or not banknotes have been sent into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) in the money depositing/dispensing machine  30  from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) of the money change machine  20  when the plurality of the storage cassettes  40  are used in one collection process. This inhibits the operator from forgetting to mount one of more of the plurality of the storage cassettes  40  to the banknote handling device  32  of the money depositing/dispensing machine  30 . Therefore, an error in calculation can be prevented from occurring in the money depositing/dispensing machine  30 . Such a technical matter will be described below in detail. 
     In the money handling system  10 , in a case where the collection process is performed using the plurality of the storage cassettes  40 , when a certain storage cassette  40  (the empty storage cassette  40 ) among the plurality of the storage cassettes  40  is mounted to the cassette mounting unit  22   c  of the banknote handling device  22 , and banknotes, as proceeds from sales, which are stored in the storage/feeding unit  22   a  of the banknote handling device  22  have been stored in this storage cassette  40 , information indicating whether or not the storage cassette  40  mounted to the cassette mounting unit  22   c  is the last cassette, and information on the number indicating the order in which the storage cassette  40  has been used in the collection process are written into the storage medium  42  of the storage cassette  40  by the reader writer  22   d .  FIG. 8  shows in detail such information written into the storage medium  42  of the storage cassette  40 . As described above, identification information (specifically, identification number of the storage cassette  40 ) of the storage cassette  40  is stored in the storage medium  42 . Information indicating whether or not the storage cassette  40  mounted to the cassette mounting unit  22   c  is the last cassette is written into the storage medium  42  by the reader writer  22   d . Specifically, as shown in  FIG. 8 , in the storage medium  42 , information of “0” is written when the storage cassette  40  is not the last cassette, and information of “1” is written when the storage cassette  40  is the last cassette (in the example shown in  FIG. 8 , the storage cassette  40  having the identification number: 001 has been mounted last to the cassette mounting unit  22   c  of the banknote handling device  22  in the collection process). As shown in  FIG. 8 , information on the number indicating the order in which the storage cassette  40  has been used in the collection process is written into the storage medium  42  by the reader writer  22   d  (in the example shown in  FIG. 8 , the storage cassette  40  having the identification number: 001 has been mounted fifth to the cassette mounting unit  22   c  of the banknote handling device  22  in the collection process, and this storage cassette  40  has been mounted last to the cassette mounting unit  22   c  in one collection process). 
     The plurality of the storage cassettes  40  are conveyed from the front office region  12  to the back office region  14  by the clerk in charge of the register, and the storage cassettes  40  are mounted one by one to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 . In the present embodiment, an operation rule in which the storage cassette  40  to which banknotes have been sent last from the banknote handling device  22  of the money change machine  20  is to be firstly mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  is adopted. Specifically, when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , information is read from the storage medium  42  disposed in the storage cassette  40  by the reader writer  32   d , and information (that is, information indicating whether or not banknotes have been sent last from the banknote handling device  22  of the money change machine  20 ) indicating whether or not the current storage cassette  40  is the storage cassette  40  which has been mounted last to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20  is also read from the storage medium  42  by the reader writer  32   d . In a case where the storage cassette  40  which has been firstly mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  is not the storage cassette  40  which has been mounted last to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , the mounting order determination unit  52  determines that an error occurs in the order in which the storage cassette  40  is mounted to the banknote handling device  32  in the money depositing/dispensing machine  30 . When the mounting order determination unit  52  determines that an error occurs in the order in which the storage cassette  40  is mounted to the banknote handling device  32  in the money depositing/dispensing machine  30 , information indicating that the storage cassette  40  mounted to the cassette mounting unit  32   c  of the banknote handling device  32  is not the storage cassette  40  which has been collected last from the money change machine  20  is displayed on the operation/display unit  39   a  as shown in  FIG. 9 . A message for prompting the operator to re-mount another storage cassette  40  to the cassette mounting unit  32   c  of the banknote handling device  32  is displayed on the operation/display unit  39   a . Thus, the operator is allowed to know that an error occurs in the order in which the storage cassette  40  is mounted to the banknote handling device  32  in the money depositing/dispensing machine  30 . 
     Meanwhile, in a case where the storage cassette  40  which has been firstly mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  is the storage cassette  40  which has been mounted last to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , the mounting order determination unit  52  determines that the order in which the storage cassette  40  is mounted to the banknote handling device  32  in the money depositing/dispensing machine  30  is correct. In this case, information on the number indicating the order in which the storage cassette  40  has been used in the collection process is read from the storage medium  42  of the storage cassette  40  by the reader writer  32   d , whereby the controller  38  can obtain information on the number of the storage cassettes  40  which have been used in the collection process. That is, in a case where the storage cassette  40  for which the information as shown in  FIG. 8  is stored in the storage medium  42  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , the mounting order determination unit  52  determines that the order in which the storage cassette  40  is mounted to the banknote handling device  32  in the money depositing/dispensing machine  30  is correct, and the controller  38  obtains information indicating that the five storage cassettes  40  have been used in the collection process. Thereafter, the clerk in charge of the register mounts the second and subsequent storage cassettes  40  to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , and banknotes as proceeds from sales are sent from the storage cassettes  40  to the storage/feeding unit  32   a . In a case where the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  remains, a screen as shown in  FIG. 10  is displayed on the operation/display unit  39   a . Specifically, information indicating that the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  is present is displayed on the operation/display unit  39   a , and a message for prompting the operator to mount, to the cassette mounting unit  32   c , the storage cassette  40  which has not been mounted is displayed on the operation/display unit  39   a . Thus, the operator is allowed to know that, among the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  in the banknote handling device  22  of the money change machine  20 , the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  of the banknote handling device  32  is present. When all the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  in the banknote handling device  22  of the money change machine  20  have been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , and all the banknotes have been sent from each storage cassette  40  to the storage/feeding unit  32   a  of the banknote handling device  32 , the collection process using the plurality of the storage cassettes  40  ends. 
     Thus, the determination unit  51  determines whether or not banknotes have been sent from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) in the money change machine  20 , into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) in the money depositing/dispensing machine  30  when the plurality of the storage cassettes  40  are used in one collection process. In a case where a plurality of the money change machines  20  are disposed as shown in  FIG. 1 , the determination unit  51  determines, for each money change machine  20 , whether or not banknotes have been sent from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  in the money change machine  20 , into the banknote handling device  32  in the money depositing/dispensing machine  30 . 
     In the present embodiment, in a case where the collection process is performed using the plurality of the storage cassettes  40 , while the storage cassettes  40  are being mounted one by one to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , the depositing of banknotes in the banknote handling device  32  can be stopped. Specifically, as shown in  FIG. 10 , when the operator such as the clerk in charge of the register presses a “forced termination” button displayed on the operation/display unit  39   a  in a state where the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  remains, depositing of banknotes from the storage cassettes  40  in the banknote handling device  32  is stopped. In this case, the controller  38  outputs information on the storage cassette  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) of the money change machine  20  and which has not sent the banknotes into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) of the money depositing/dispensing machine  30 , and the outputted information is displayed on the operation/display unit  39   a . Specifically, for example, information on the number of the storage cassettes  40  which have not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  at a point in time when the collection process is stopped, and the identification information (specifically, identification numbers) of the storage cassettes  40  is displayed on the operation/display unit  39   a . Information on banknotes stored in the storage cassettes  40  which have not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  may also be displayed on the operation/display unit  39   a . Thus, when the collection process is stopped, the operator is allowed to recognize the number of the storage cassettes  40  which have not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  and the identification information of the storage cassettes  40 . 
     The money handling system according to the present embodiment is not limited to the money handling system in which the storage medium  42  is disposed in the storage cassette  40  and the usage of the storage cassette  40  is stored in the storage medium  42  as shown in  FIG. 1  to  FIG. 10 . As another exemplary money handling system of the present embodiment, a money handling system in which, instead of the storage medium  42 , a recognition medium  44  such as a barcode is disposed in the storage cassette  40  as shown in  FIG. 11  to  FIG. 14 , may be used. Such an aspect will be described below. 
       FIG. 11  to  FIG. 14  illustrate a money handling system  10   a  according to another example of the present embodiment and a money change machine  20   a  and a money depositing/dispensing machine  30   a  which are disposed in the money handling system  10   a . In the description of the money change machine  20   a  and the money depositing/dispensing machine  30   a  shown in  FIG. 11  to  FIG. 14 , the same components as in the money change machine  20  and the money depositing/dispensing machine  30  shown in  FIG. 1  to  FIG. 10  are denoted by the same reference numerals, and the description thereof is omitted. 
     As described above, in the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , each of the plurality of the storage cassettes  40  used for delivering banknotes between the money change machine  20   a  and the money depositing/dispensing machine  30   a  has its corresponding identification information such as an identification number. Each of the storage cassettes  40  has the recognition medium  44  such as a barcode indicating the identification information of the storage cassette  40 . As shown in  FIG. 12 , the banknote handling device  22  of the money change machine  20  has a barcode reader  22   e  for reading the identification information of the storage cassette  40  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  22   c . Since the barcode reader  22   e  having such a configuration is disposed, when the storage cassette  40  is mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , the identification information such as the identification number of the storage cassette  40  is read from the recognition medium  44  by the barcode reader  22   e  and transmitted to the controller  28 . As shown in  FIG. 13 , the banknote handling device  32  of the money depositing/dispensing machine  30  also has a barcode reader  32   e  for reading the identification information of the storage cassette  40  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  32   c . Since the barcode reader  32   e  having such a configuration is disposed, when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , the identification information such as the identification number of the storage cassette  40  is read from the recognition medium  44  by the barcode reader  32   e  and transmitted to the controller  38 . 
     In the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , each money change machine  20   a  and the money depositing/dispensing machine  30   a  are connected so as to be communicable with each other via a local area network (LAN)  16  or the like in a wired or wireless manner. Thus, signal transmission and reception can be performed between the controller  28  of each money change machine  20   a  and the controller  38  of the money depositing/dispensing machine  30   a . In the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , each money change machine  20   a  and the money depositing/dispensing machine  30   a  may not necessarily be connected so as to be communicable with each other. In a modification of the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , each money change machine  20   a  and the money depositing/dispensing machine  30   a  may not be connected so as to be communicable with each other. 
     In the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , instead of the usage of each storage cassette  40  being written into the storage medium  42  disposed in the storage cassette  40 , the usage of each storage cassette  40  is stored in the memory  39   b  of the money depositing/dispensing machine  30   a  so as to be associated with the identification number of the storage cassette  40 .  FIG. 14  shows a table representing a relationship, between the identification number of the storage cassette  40  and the usage of the storage cassette  40 , which is stored in the memory  39   b  of the money depositing/dispensing machine  30   a . As shown in  FIG. 14 , the usage of each storage cassette  40  is stored as collection, replenishment, or storage in the memory  39   b  so as to be associated with the identification number of the storage cassette  40 . When the usage determination unit  50  determines the usage of the storage cassette  40 , the usage of the storage cassette  40  stored in the memory  39   b  is rewritten. 
     More specifically, in the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , in a case where, in the collection process, the empty storage cassette  40  has been mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , and the operator thereafter inputs, through the operation/display unit  29   a , an instruction for performing the collection process, the identification number of the storage cassette  40  which has been read from the recognition medium  44  by the barcode reader  22   e  and information indicating that the usage of the storage cassette  40  corresponding to this identification number is collection are transmitted from the controller  28  of the money change machine  20  to the controller  38  of the money depositing/dispensing machine  30 . Among the usages of the storage cassettes  40  of the identification numbers stored in the memory  39   b , the usage of the storage cassette  40 , of the identification number, which has been mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20  is rewritten as collection. In the banknote handling device  22 , banknotes as proceeds from sales are fed out from the storage/feeding unit  22   a , and the banknotes having been fed out are stored in the storage cassette  40 . Thereafter, the storage cassette  40  is dismounted from the cassette mounting unit  22   c  and conveyed from the front office region  12  to the back office region  14 , and the storage cassette  40  is thereafter mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 . In this case, when the usage of the storage cassette  40  corresponding to the storage cassette identification number which is read from the recognition medium  44  of the storage cassette  40  by the barcode reader  32   e  is determined as collection based on the information stored in the memory  39   b , banknotes as proceeds from sales are sent from the storage cassette  40  to the storage/feeding unit  32   a  (see  FIG. 6 ). 
     In the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , in a case where, in the replenishing process, the empty storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , and the operator thereafter inputs, through the operation/display unit  39   a , an instruction for performing the replenishing process, the usage of the storage cassette  40 , of the identification number, which is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , among the usages of the storage cassettes  40  having the identification numbers stored in the memory  39   b , is rewritten as replenishment. In the banknote handling device  32 , banknotes as change fund are fed out from the storage/feeding unit  32   a  and banknotes having been fed out are stored in the storage cassette  40  (see  FIG. 6 ). Thereafter, in a case where the storage cassette  40  is dismounted from the cassette mounting unit  32   c  and conveyed from the back office region  14  to the front office region  12 , and the storage cassette  40  is thereafter mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20 , the identification number of the storage cassette  40  is read from the recognition medium  44  of the storage cassette  40  by the barcode reader  22   e . In a case where, by communication between the controller  28  of the money change machine  20  and the controller  38  of the money depositing/dispensing machine  30 , the usage of the storage cassette  40  corresponding to the storage cassette identification number which is read from the recognition medium  44  of the storage cassette  40  by the barcode reader  22   e  is determined as replenishment based on information stored in the memory  39   b , banknotes as change fund are sent from the storage cassette  40  to the storage/feeding unit  22   a.    
     In a case where the storage/feeding unit  32   a  in the banknote handling device  32  of the money depositing/dispensing machine  30  is in a full state or a nearly full state, and banknotes can no longer be stored in the storage/feeding unit  32   a , when the empty storage cassette  40  is mounted to the cassette mounting unit  32   c , the usage determination unit  50  determines that the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c  is storage. In this case, among the usages of the storage cassettes  40  having the identification numbers stored in the memory  39   b , the usage of the storage cassette  40  corresponding to the storage cassette identification number which is read from the recognition medium  44  of the storage cassette  40  by the barcode reader  32   e  is rewritten as storage. After the usage of the storage cassette  40  which has the identification number stored in the memory  39   b  and is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30  is rewritten as storage, banknotes are fed out from the storage/feeding unit  32   a  in the banknote handling device  32 , and banknotes having been fed out are stored in the storage cassette  40  (see  FIG. 6 ). Thus, the controller  38  performs control so as to send banknotes from the storage/feeding unit  32   a  to the empty storage cassette  40  mounted to the cassette mounting unit  32   c  according to a storing state of banknotes in the storage/feeding unit  32   a . Thereafter, in a case where an excess space is formed in the storage/feeding unit  32   a  by the replenishing process being performed by the money depositing/dispensing machine  30 , and the storage cassette  40 , for storage, which stores banknotes is thereafter mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 , the identification number of the storage cassette  40  is read from the recognition medium  44  of the storage cassette  40  by the barcode reader  32   e . When the usage of the storage cassette  40  corresponding to the read identification number of the storage cassette  40  is storage according to information stored in the memory  39   b , banknotes are fed out from the storage cassette  40 , and the banknotes having been fed out are stored in the storage/feeding unit  32   a  ( FIG. 6 ). 
     In still another example of the money handling system of the present embodiment, in addition to the recognition medium  44  such as a barcode being disposed in the storage cassette  40  in place of the storage medium  42 , the clerk in charge of the register may have a portable storage medium  46  such as an IC card as shown in  FIG. 15  to  FIG. 18 . Such an aspect will be described below. 
       FIG. 15  to  FIG. 18  illustrate a money handling system  10   b  according to another example of the present embodiment and a money change machine  20   b  and a money depositing/dispensing machine  30   b  which are disposed in the money handling system  10   b . In the description of the money change machine  20   b  and the money depositing/dispensing machine  30   b  shown in  FIG. 15  to  FIG. 18 , the same components as in the money change machine  20  and the money depositing/dispensing machine  30  shown in  FIG. 1  to  FIG. 10  are denoted by the same reference numerals, and the description thereof is omitted. 
     As described above, in the money handling system  10   b  shown in  FIG. 15  to  FIG. 18 , the plurality of the storage cassettes  40  are used to deliver banknotes between the money change machine  20   b  and the money depositing/dispensing machine  30   b  and each storage cassette  40  has its corresponding identification information such as an identification number. The storage cassette  40  has the recognition medium  44  such as a barcode representing the identification information of the storage cassette  40 . The clerk in charge of the register has the portable storage medium  46  such as an IC card. In the portable storage medium  46 , for example, identification information such as the identification number of the storage cassette  40  used in the collection process and the replenishing process, information (specifically, information on the number of banknotes for each denomination, and the like) on banknotes stored in the storage cassette  40  used in the collection process and the replenishing process, and identification information of the money change machine  20   b  for which the collection process and the replenishing process are performed, are stored in addition to the identification information of the operator who has the portable storage medium  46 . 
     As shown in  FIG. 16 , the banknote handling device  22  of the money change machine  20   b  has the barcode reader  22   e  for reading identification information of the storage cassette  40  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  22   c . By the barcode reader  22   e  having such a configuration being disposed, when the storage cassette  40  is mounted to the cassette mounting unit  22   c  in the banknote handling device  22  of the money change machine  20   b , the identification information such as the identification number of the storage cassette  40  is read from the recognition medium  44  by the barcode reader  22   e  and transmitted to the controller  28 . The money change machine  20   b  has a reader writer  29   e  for reading information from the portable storage medium  46  such as an IC card of the operator, and writing information in the portable storage medium  46 . The reader writer  29   e  having such a configuration is connected to the controller  28 . 
     As shown in  FIG. 17 , the banknote handling device  32  of the money depositing/dispensing machine  30   b  also has the barcode reader  32   e  for reading the identification information of the storage cassette  40  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  32   c . By the barcode reader  32   e  having such a configuration being disposed, when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b , the identification information such as the identification number of the storage cassette  40  is read from the recognition medium  44  by the barcode reader  32   e  and transmitted to the controller  38 . The money depositing/dispensing machine  30   b  has a reader writer  39   e  for reading information from the portable storage medium  46  such as an IC card of the operator, and writing information in the portable storage medium  46 . The reader writer  39   e  having such a configuration is connected to the controller  38 . 
     Next, an operation (that is, operation indicated by reference numeral (a) in  FIG. 15 ) performed by the money handling system  10   b  having such a configuration in the collection process will be described. When the business hours of the store end, the clerk in charge of the register who has performed commodity settlement at the settlement place collects money and mediums (for example, vouchers and the like) other than the money from the money change machine  20   b . Specifically, the clerk in charge of the register firstly causes the reader writer  29   e  of the money change machine  20   b  to read the portable storage medium  46  which stores the identification information such as the identification number of the clerk in charge of the register. Thus, the controller  28  obtains the identification information of the operator and performs authentication of the authority of the operator. When the authority of the operator which has been read from the portable storage medium  46  by the reader writer  29   e  is authenticated as the authority of the operator who is authorized to collect banknotes from the banknote handling device  22  of the money change machine  20   b , the clerk in charge of the register mounts the empty storage cassette  40  to the cassette mounting unit  22   c  of the banknote handling device  22  to store banknotes, as proceeds from sales, which are stored in the storage/feeding unit  22   a  of the banknote handling device  22 , in the storage cassette  40 . After banknotes as proceeds from sales and the like have been collected from the banknote handling device  22  and the like, when the operator causes the reader writer  29   e  to read the portable storage medium  46  again, information (specifically, the number of banknotes for each denomination) and the like on, for example, banknotes collected from the banknote handling device  22  or the like is written into the portable storage medium  46  by the reader writer  29   e.    
     The clerk in charge of the register who has collected money and mediums other than the money from the money change machine  20   b  in the front office region  12  collectively conveys the storage cassette  40  and the like from the front office region  12  to the back office region  14 . Thereafter, the clerk in charge of the register causes the reader writer  39   e  of the money depositing/dispensing machine  30   b  to read information stored in the portable storage medium  46  of the clerk. Thus, the controller  38  obtains the identification information of the operator and performs authentication of the authority of the operator. When the authority of the operator which has been read from the portable storage medium  46  by the reader writer  39   e  is authenticated as the authority of the operator who is authorized to deposit banknotes from the storage cassette  40  in the banknote handling device  32  of the money depositing/dispensing machine  30   b , the clerk in charge of the register mounts the storage cassette  40  to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b . Thus, banknotes as proceeds from sales which are stored in the storage cassette  40  are fed out from the storage cassette  40 , sent into the housing of the banknote handling device  32 , and stored in the storage/feeding unit  32   a  of the banknote handling device  32 . 
     Also in the money handling system  10   b  shown in  FIG. 15  to  FIG. 18 , similarly to the money handling system  10  shown in  FIG. 1  to  FIG. 10 , in a case where a large number of banknotes are to be collected from the money change machine  20   b  in one transaction (in other words, collection process performed at one time), a plurality of the storage cassettes  40  may be used. In this case, the plurality of the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) in the money change machine  20   b  are conveyed to the money depositing/dispensing machine  30   b , and banknotes are thereafter stored into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) of the money depositing/dispensing machine  30   b , from the storage cassettes  40  one by one, in the money depositing/dispensing machine  30   b.    
     More specifically, in the money handling system  10   b , in a case where the collection process is performed using the plurality of the storage cassettes  40 , after banknotes as proceeds from sales are sent to the plurality of the storage cassettes  40  from the storage/feeding unit  22   a  of the banknote handling device  22 , when the operator causes the reader writer  29   e  to read the portable storage medium  46  again, the identification information such as the identification number of each storage cassette  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22  and the order in which the storage cassette  40  has been mounted to the cassette mounting unit  22   c  are written into the portable storage medium  46  by the reader writer  29   e  (see  FIG. 18 ). That is, in the example shown in  FIG. 18 , information indicating that the storage cassettes  40  having the identification numbers of 008, 002, 001, 003, and 005 have been mounted to the cassette mounting unit  22   c  of the banknote handling device  22  in this order, and banknotes have been sent to these storage cassettes  40  from the storage/feeding unit  22   a  of the banknote handling device  22 , is written into the portable storage medium  46  by the reader writer  29   e . At this time, information on the banknotes stored in each storage cassette  40  is also written into the portable storage medium  46  by the reader writer  29   e  so as to be associated with the identification number of the storage cassette  40 . 
     The clerk in charge of the register conveys the plurality of the storage cassettes  40  from the front office region  12  to the back office region  14 , and the storage cassettes  40  are mounted one by one to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b . In the present embodiment, before the storage cassette  40  is mounted to the cassette mounting unit  32   c , information stored in the portable storage medium  46  of the clerk in charge of the register is read by the reader writer  39   e  of the money depositing/dispensing machine  30   b . Thus, the controller  38  can obtain the identification information such as the identification number of each storage cassette  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22  and the order in which the storage cassette  40  has been mounted to the cassette mounting unit  22   c , as shown in  FIG. 18 . Thus, information on the number of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22  is also obtained by the controller  38 . 
     Thereafter, the clerk in charge of the register sequentially mounts the plurality of the storage cassettes  40  to the cassette mounting unit  32   c  of the banknote handling device  32  of the money depositing/dispensing machine  30   b , whereby banknotes as proceeds from sales are sent from each storage cassette  40  to the storage/feeding unit  32   a . In a case where the identification number of the storage cassette  40  which has been read by the barcode reader  32   e  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  32   c  is not identical to the identification number, of the storage cassette  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , which has been read from the portable storage medium  46  by the reader writer  39   e , the controller  38  determines that an incorrect storage cassette  40  is mounted to the cassette mounting unit  32   c . In this case, a message indicating that an incorrect storage cassette  40  has been mounted to the cassette mounting unit  32   c  is displayed on the operation/display unit  39   a . Meanwhile, in a case where the identification number of the storage cassette  40  which has been read by the barcode reader  32   e  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  32   c  is identical to the identification number, of the storage cassette  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , which has been read from the portable storage medium  46  by the reader writer  39   e , banknotes are fed out from the storage cassette  40  mounted to the cassette mounting unit  32   c , and the banknotes having been fed out are sent to the storage/feeding unit  32   a.    
     In a case where the number of the storage cassettes  40  mounted to the cassette mounting unit  32   c  does not reach the number, of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , which has been read from the portable storage medium  46  by the reader writer  39   e , the controller  38  determines that the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  remains. In this case, the screen as shown in  FIG. 10  is displayed on the operation/display unit  39   a . Specifically, information indicating that the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b  is present is displayed on the operation/display unit  39   a , and a message for prompting the operator to mount, to the cassette mounting unit  32   c , the storage cassette  40  which has not been mounted is displayed on the operation/display unit  39   a . Thus, the operator knows that, among the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  in the banknote handling device  22  of the money change machine  20   b , the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  of the banknote handling device  32  is present. When all the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  in the banknote handling device  22  of the money change machine  20   b  have been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b , and all the banknotes have been sent from each storage cassette  40  to the storage/feeding unit  32   a  of the banknote handling device  32 , the collection process using the plurality of the storage cassettes  40  ends. 
     Thus, when the plurality of the storage cassettes  40  are used in one collection process, the determination unit  51  determines whether or not banknotes have been sent, from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) in the money change machine  20   b , into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) in the money depositing/dispensing machine  30   b . As shown in  FIG. 15 , in a case where a plurality of the money change machines  20   b  are disposed, the determination unit  51  determines, for each money change machine  20   b , whether or not banknotes have been sent, from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  in the money change machine  20   b , into the banknote handling device  32  in the money depositing/dispensing machine  30   b.    
     In still another example of the money handling system of the present embodiment, as shown in  FIG. 19 , a money handling system  10   c  in which each money change machine  20   b  and the money depositing/dispensing machine  30   b  are connected so as to be communicable with each other via the LAN  16  or the like in a wired or wireless manner. The money handling system  10   c  shown in  FIG. 19  is different from the money handling system  10   b  shown in  FIG. 15  to  FIG. 18  only in that the portable storage medium  46  such as an IC card is not used but each money change machine  20   b  and the money depositing/dispensing machine  30   b  are connected so as to be communicable with each other via the LAN  16  or the like in a wired or wireless manner in the money handling system  10   c . The other components are almost the same therebetween. In the description of the money handling system  10   c  shown in  FIG. 19 , the same components as in the money handling system  10   b  shown in  FIG. 15  to  FIG. 18  are denoted by the same reference numerals, and the description thereof is omitted. 
     An operation (that is, operation indicated by reference numeral (a) in  FIG. 19 ) performed by the money handling system  10   c  shown in  FIG. 19  in the collection process will be described. When the business hours of the store end, the clerk in charge of the register who has performed commodity settlement at the settlement place collects money and mediums (for example, vouchers and the like) other than the money from the money change machine  20   b . Specifically, the clerk in charge of the register mounts the empty storage cassette  40  to the cassette mounting unit  22   c  of the banknote handling device  22 , to store banknotes, as proceeds from sales, which are stored in the storage/feeding unit  22   a  of the banknote handling device  22 , in the storage cassette  40 . The identification information such as the identification number of the storage cassette  40  is read by the barcode reader  22   e  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  22   c , and the identification information of the storage cassette  40  is transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b . Information (specifically, the number of banknotes for each denomination) on banknotes which have been sent to the storage cassette  40  from the storage/feeding unit  22   a  of the banknote handling device  22  is also transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b.    
     In the front office region  12 , the clerk in charge of the register who has collected the money and the mediums other than the money from the money change machine  20   b  collectively conveys the storage cassette  40  and the like from the front office region  12  to the back office region  14 . Thereafter, the clerk in charge of the register mounts the storage cassette  40  to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b . Thus, banknotes, as proceeds from sales, which are stored in the storage cassette  40  are fed out from the storage cassette  40  and sent into the housing of the banknote handling device  32 , and stored in the storage/feeding unit  32   a  of the banknote handling device  32 . 
     Also in the money handling system  10   c  shown in  FIG. 19 , similarly to the money handling system  10  shown in  FIG. 1  to  FIG. 10  and the money handling system  10   b  shown in  FIG. 15  to  FIG. 18 , in a case where a large number of banknotes are to be collected from the money change machine  20   b  in one transaction (in other words, collection process performed at one time), a plurality of the storage cassettes  40  may be used. In this case, the plurality of the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) in the money change machine  20   b  are conveyed to the money depositing/dispensing machine  30   b , and banknotes are thereafter stored into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) of the money depositing/dispensing machine  30   b , from the storage cassettes  40  one by one, in the money depositing/dispensing machine  30   b.    
     More specifically, in the money handling system  10   c , in a case where the collection process is performed using the plurality of the storage cassettes  40 , after banknotes as proceeds from sales have been sent to the plurality of the storage cassettes  40  from the storage/feeding unit  22   a  of the banknote handling device  22 , the identification information such as the identification numbers of the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , and information on the order in which the storage cassettes  40  have been mounted to the cassette mounting unit  22   c  are transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b . Information on banknotes stored in each storage cassette  40  is associated with the identification number of the storage cassette  40  and transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b . Thus, information on the number of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22  is also obtained by the controller  38 . 
     The clerk in charge of the register conveys the plurality of the storage cassettes  40  from the front office region  12  to the back office region  14 , and mounts the storage cassettes  40  one by one to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b . Thus, banknotes as proceeds from sales are sent from each storage cassette  40  to the storage/feeding unit  32   a . In a case where the identification number of the storage cassette  40  which has been read by the barcode reader  32   e  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  32   c  is not identical to the identification number, of the storage cassette  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , which has been transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b , the controller  38  determines that an incorrect storage cassette  40  is mounted to the cassette mounting unit  32   c . In this case, a message indicating that an incorrect storage cassette  40  has been mounted to the cassette mounting unit  32   c  is displayed on the operation/display unit  39   a . Meanwhile, in a case where the identification number of the storage cassette  40  which has been read by the barcode reader  32   e  from the recognition medium  44  of the storage cassette  40  mounted to the cassette mounting unit  32   c  is identical to the identification number, of the storage cassette  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , which has been transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b , banknotes are fed out from the storage cassette  40  mounted to the cassette mounting unit  32   c , and the banknotes having been fed out are sent to the storage/feeding unit  32   a.    
     In a case where the number of the storage cassettes  40  mounted to the cassette mounting unit  32   c  does not reach the number, of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  of the banknote handling device  22 , which has been transmitted via the LAN  16  from the controller  28  of the money change machine  20   b  to the controller  38  of the money depositing/dispensing machine  30   b , the controller  38  determines that the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  remains. In this case, the screen as shown in  FIG. 10  is displayed on the operation/display unit  39   a . Specifically, information indicating that the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b  is present is displayed on the operation/display unit  39   a , and a message for prompting the operator to mount, to the cassette mounting unit  32   c , the storage cassette  40  which has not been mounted is displayed on the operation/display unit  39   a . Thus, the operator is allowed to know that, among the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  in the banknote handling device  22  of the money change machine  20   b , the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  of the banknote handling device  32  is present. When all the plurality of the storage cassettes  40  to which banknotes have been sent from the storage/feeding unit  22   a  in the banknote handling device  22  of the money change machine  20   b  have been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b , and all the banknotes have been sent from each storage cassette  40  to the storage/feeding unit  32   a  of the banknote handling device  32 , the collection process using the plurality of the storage cassettes  40  ends. 
     Thus, in the banknote collection process, when the plurality of the storage cassettes  40  are used, the determination unit  51  determines whether or not banknotes have been sent, from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) in the money change machine  20   b , into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) in the money depositing/dispensing machine  30   b . When a plurality of the money change machines  20   b  are disposed as shown in  FIG. 15  and  FIG. 19 , the determination unit  51  determines, for each money change machine  20   b , whether or not banknotes have been sent, from all the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  in the money change machine  20   b , into the banknote handling device  32  in the money depositing/dispensing machine  30   b.    
     In the money handling system  10   b  shown in  FIG. 15  to  FIG. 18  and the money handling system  10   c  shown in  FIG. 19 , in a case where the collection process is performed using the plurality of the storage cassettes  40 , while the storage cassettes  40  are being mounted one by one to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b , depositing of banknotes in the banknote handling device  32  can be stopped. Specifically, as shown in  FIG. 10 , in a case where the operator such as the clerk in charge of the register presses the “forced termination” button displayed on the operation/display unit  39   a  in a state where the storage cassette  40  which has not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b  remains, depositing of banknotes from the storage cassettes  40  in the banknote handling device  32  is stopped. In this case, the controller  38  outputs information on the storage cassettes  40  to which banknotes have been sent from the banknote handling device  22  (specifically, the storage/feeding unit  22   a ) of the money change machine  20   b  and which has not sent the banknotes into the banknote handling device  32  (specifically, the storage/feeding unit  32   a ) of the money depositing/dispensing machine  30   b , and the outputted information is displayed on the operation/display unit  39   a . Specifically, the information on, for example, the number of the storage cassettes  40  which have not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b  at a point in time when the collection process has been stopped and identification information (specifically, the identification numbers) of the storage cassettes  40  are displayed on the operation/display unit  39   a . Information on banknotes stored in the storage cassettes  40  which have not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b  may also be displayed on the operation/display unit  39   a . Thus, when the collection process is stopped, the operator is allowed to recognize the number of the storage cassettes  40  which have not been mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30   b  and the identification information of the storage cassettes  40 . 
     As the money handling system  10   c  shown in  FIG. 19 , an exemplary money handling system in which each money change machine  20   b  and the money depositing/dispensing machine  30   b  are connected so as to be communicable with each other via the LAN  16 , and each storage cassette  40  has the recognition medium  44  such as a barcode, has been described. The present embodiment is not limited to such an example. In still another example of the present embodiment, the money handling system  10  shown in  FIG. 1  to  FIG. 10  may be configured such that each money change machine  20  and the money depositing/dispensing machine  30  are connected so as to be communicable with each other via the LAN, and, when a plurality of the storage cassettes  40  are used in the collection process, information on the number of storage cassettes to which banknotes have been sent from the money change machine  20  is transmitted from the controller  28  of the money change machine  20  to the controller  38  of the money depositing/dispensing machine  30 . In this case, the determination unit  51  determines whether or not banknotes have been sent into the money depositing/dispensing machine  30  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20 , based on the number, of the storage cassettes  40  to which banknotes have been sent from the money change machine  20  in the collection process, which has been transmitted from the controller  28  of the money change machine  20  to the controller  38  of the money depositing/dispensing machine  30 , and the number of the storage cassettes  40  mounted to the money depositing/dispensing machine  30 . 
     In the money handling systems  10 ,  10   a  according to the present embodiment having the above-described configurations, and the money depositing/dispensing machines  30 ,  30   a  disposed in the money handling systems  10 ,  10   a , banknotes are sent from the storage/feeding unit  32   a  to the empty storage cassette  40  mounted to the cassette mounting unit  32   c , according to a storing state of banknotes in the storage/feeding unit  32   a . In a case where banknotes are thus sent from the storage/feeding unit  32   a  to the empty storage cassette  40  according to a storing state of banknotes in the storage/feeding unit  32   a , even when banknotes in the storage/feeding unit  32   a  become insufficient while change fund is prepared, replenishment of banknotes can be performed merely by mounting the storage cassette  40 , whereby, for example, an operation of taking out banknotes from a collection cassette (not shown) can be eliminated, and this reduces an operator&#39;s workload and a replenishing time. 
     More specifically, in a conventional money handling system, a storage cassette which is detachably mounted to a banknote handling device of a money depositing/dispensing machine may have been used for collection and replenishment but has not been used for storage. Therefore, in the conventional money handling system, in a case where the entire collection process in which all the money are collected from a plurality of money change machines and deposited in the money depositing/dispensing machine is periodically performed, when the storage/feeding unit disposed in the money depositing/dispensing machine has been in a full state and money can no longer be stored in the storage/feeding unit during the entire collection process, the process of depositing money collected from the money change machine in the money depositing/dispensing machine is stopped and money needs to be collected from the storage/feeding unit in the full state. However, in a case where the replenishing process of replenishing a plurality of money change machines with change fund is performed after the entire collection process, when change fund that exceeds the capacity of the storage/feeding unit is necessary, the money collected in the collection cassette is taken out with hands and the replenishing process in the money depositing/dispensing machine needs to be performed, and an operator&#39;s workload and the time for the replenishing process tend to be increased. Meanwhile, in the present embodiment, by banknotes being sent from the storage/feeding unit  32   a  to the empty storage cassette  40  mounted to the cassette mounting unit  32   c  according to a storing state of banknotes in the storage/feeding unit  32   a , banknotes stored in the storage/feeding unit  32   a  can be temporarily stored in the storage cassette  40 . Therefore, in a case where the replenishing process of replenishing a plurality of the money change machines  20 ,  20   a  with change fund is performed after the entire collection process, when change fund which exceeds the capacity of the storage/feeding unit  32   a  is necessary, banknotes are returned from the storage cassette  40  to the storage/feeding unit  32   a  merely by mounting, to the money depositing/dispensing machine  30 ,  30   a , the storage cassette  40  that temporarily stores banknotes, whereby the storage/feeding unit  32   a  can be replenished with banknotes. Thus, in the present embodiment, for example, an operation of taking out banknotes from the collection cassette (not shown) can be eliminated, and this reduces an operator&#39;s workload and a replenishing time. 
     In the money handling systems  10 ,  10   a  according to the present embodiment and the money depositing/dispensing machines  30 ,  30   a  disposed in the money handling systems  10 ,  10   a , as described above, the usage determination unit  50  is disposed for determining the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c , according to a storing state of banknotes in the storage/feeding unit  32   a . Thus, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c  is determined according to a storing state of banknotes in the storage/feeding unit  32   a , whereby the usage of the storage cassette  40  can be made appropriate. 
     In the money handling systems  10 ,  10   a  according to the present embodiment and the money depositing/dispensing machines  30 ,  30   a  disposed in the money handling systems  10 ,  10   a , as described above, the usage determination unit  50  determines, as storage, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c  when banknotes can no longer be stored in the storage/feeding unit  32   a . The usage determination unit  50  can determine, as storage, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c  only in a case where no banknotes are stored in the storage cassette  40  when the storage cassette  40  is mounted to the cassette mounting unit  32   c . In other words, in a case where the storage cassette  40  is mounted to the cassette mounting unit  32   c , when banknotes are stored in the storage cassette  40 , the banknotes are considered to have been collected from the banknote handling device  22  of the money change machine  20 . Therefore, the usage determination unit  50  determines, as collection, the usage of the storage cassette  40  mounted to the cassette mounting unit  32   c , and banknotes are fed out from the storage cassette  40  and stored in the storage/feeding unit  32   a.    
     In the money handling system  10  shown in  FIG. 1  to  FIG. 10 , the storage cassette  40  has the storage medium  42 , and the banknote handling device  32  of the money depositing/dispensing machine  30  has the reader writer  32   d  as a wiring unit for writing information in the storage medium  42  disposed in the storage cassette  40  which is mounted to the cassette mounting unit  32   c . Information on the usage of the storage cassette  40  which is determined by the usage determination unit  50  is written into the storage medium  42  disposed in the storage cassette  40 , by the reader writer  32   d  as the writing unit. In this case, the reader writer  32   d  also functions as a reading unit for reading information from the storage medium  42  disposed in the storage cassette  40  which is mounted to the cassette mounting unit  32   c.    
     In the money handling system  10   a  shown in  FIG. 11  to  FIG. 14 , the storage cassette  40  has the recognition medium  44  representing identification information of the storage cassette  40 , and the banknote handling device  32  of the money depositing/dispensing machine  30  has the barcode reader  32   e  as an identification information reading unit for reading the identification information of the storage cassette  40  from the recognition medium  44  disposed in the storage cassette  40  which is mounted to the cassette mounting unit  32   c . The money depositing/dispensing machine  30  has the memory  39   b , and information on the usage of the storage cassette  40  which is determined by the usage determination unit  50  is associated with the identification information of the storage cassette  40  which is read by the barcode reader  32   e  as the identification information reading unit, and stored in the memory  39   b  (see  FIG. 14 ). 
     In the money handling system  10 ,  10   b ,  10   c  according to the present embodiment having the above-described configuration, the determination unit  51  is disposed for determining whether or not banknotes have been sent into the money depositing/dispensing machine  30 ,  30   b  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20 ,  20   b  when a plurality of the storage cassettes  40  are used in the collection process in which banknotes are collected from the money change machine  20 ,  20   b  and deposited in the money depositing/dispensing machine  30 ,  30   b . Thus, whether or not banknotes have been sent into the money depositing/dispensing machine  30 ,  30   b  from all the storage cassette  40  to which banknotes have been sent from the money change machine  20 ,  20   b  is determined when a plurality of the storage cassettes  40  are used in one collection process, and this can inhibit the operator from forgetting to mount one or more of the plurality of the storage cassettes  40  to the money depositing/dispensing machine  30 ,  30   b , thereby preventing an error in calculation from occurring in the money depositing/dispensing machine  30 ,  30   b.    
     More specifically, in a conventional money handling system, when a plurality of storage cassettes are used in one collection process, the money depositing/dispensing machine cannot obtain the number of storage cassettes into which banknotes have been stored from the money change machine. Therefore, the operator may forget to mount one or more of the plurality of storage cassettes to the money depositing/dispensing machine. In this case, a problem may arise that an error in calculation occurs in the money depositing/dispensing machine. Meanwhile, in the present embodiment, whether or not money has been sent into the money depositing/dispensing machine  30 ,  30   b  from all the storage cassettes  40  to which money has been sent from the money change machine  20 ,  20   b  is determined when a plurality of the storage cassettes  40  are used in one collection process, so that the problem of the conventional money handling system can be overcome. 
     In the money handling system  10 ,  10   b ,  10   c  according to the present embodiment, as described above, information indicating whether or not banknotes have been sent into the money depositing/dispensing machine  30 ,  30   b  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20 ,  20   b  in the collection process is displayed on the operation/display unit  39   a  based on the determination result by the determination unit  51  (see  FIG. 10 ). Thus, the operation/display unit  39   a  functions as a notification unit for making notification of information indicating whether or not banknotes have been sent into the money depositing/dispensing machine  30 ,  30   b  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20 ,  20   b  in the collection process, based on the determination result by the determination unit  51 . Such a notification unit is not limited to the operation/display unit  39   a , and may make the notification to the operator by another method such as sound. 
     In the money handling system  10 ,  10   b ,  10   c  according to the present embodiment, as described above, in a case where the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20 ,  20   b  and the number of the storage cassettes  40  which have sent banknotes into the money depositing/dispensing machine  30 ,  30   b  are not identical to each other, the determination unit  51  determines that money has not been sent into the money depositing/dispensing machine  30 ,  30   b  from all the storage cassettes  40  to which money has been sent from the money change machine  20 ,  20   b  in the collection process. 
     In the money handling system  10  shown in  FIG. 1  to  FIG. 10 , in the storage medium  42  of the storage cassette  40  to which banknotes have been sent last from the money change machine  20  in the collection process, information indicating that the storage cassette  40  is the storage cassette  40  to which banknotes have been sent last and information on the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20  are written by the reader writer  22   d  (first writing unit). In the example shown in  FIG. 8 , as the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20 , information on the number indicating the order in which the storage cassette  40  has been used in the collection process is written into the storage medium  42  by the reader writer  22   d . However, the present embodiment is not limited to such an aspect. Instead of or in addition to the information on the number indicating the order in which the storage cassette  40  has been used in the collection process, the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20  may be written into the storage medium  42  by the reader writer  22   d . The determination unit  51  determines whether or not banknotes have been sent into the money depositing/dispensing machine  30  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20 , based on the number of the storage cassettes  40  mounted to the money depositing/dispensing machine  30  and the number, of the storage cassettes  40  to which banknotes have been sent from the money change machine  20  in the collection process, which is read from the storage medium  42  disposed in the storage cassette  40 , by the reader writer  32   d  (first reading unit) of the money depositing/dispensing machine  30 . 
     In the money handling system  10   b  shown in  FIG. 15  to  FIG. 18 , information on the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20   b  in the collection process is written into the portable storage medium  46  by the reader writer  29   e  (second writing unit) of the money change machine  20   b . The determination unit  51  determines whether or not banknotes have been sent into the money depositing/dispensing machine  30   b  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20   b , based on the number of the storage cassettes  40  mounted to the money depositing/dispensing machine  30   b , and the number, of the storage cassettes  40  to which banknotes have been sent from the money change machine  20   b  in the collection process, which has been read from the portable storage medium  46  by the reader writer  39   e  (second reading unit) of the money depositing/dispensing machine  30   b.    
     In the money handling system  10   c  shown in  FIG. 19 , the money change machine  20   b  and the money depositing/dispensing machine  30   b  are connected so as to be communicable with each other, and information on the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20   b  in the collection process is transmitted from the money change machine  20   b  to the money depositing/dispensing machine  30   b . The determination unit  51  determines whether or not banknotes have been sent into the money depositing/dispensing machine  30   b  from all the storage cassettes  40  to which banknotes have been sent from the money change machine  20   b , based on the number of the storage cassettes  40  mounted to the money depositing/dispensing machine  30   b  and the number, of the storage cassettes  40  to which banknotes have been sent from the money change machine  20   b  in the collection process, which has been transmitted from the money change machine  20   b  to the money depositing/dispensing machine  30   b.    
     In the money handling system  10 ,  10   b ,  10   c  according to the present embodiment, as described above, when the collection process is interrupted, the controller  38  outputs information on the storage cassette  40  to which banknotes have been sent from the money change machine  20 ,  20   b  and which has not sent banknotes into the money depositing/dispensing machine  30 ,  30   b , and the outputted information is displayed on the operation/display unit  39   a . Thus, the controller  38  functions as an unprocessed cassette information output unit for outputting information on the storage cassette  40  to which banknotes have been sent from the money change machine  20 ,  20   b  and which has not sent banknotes into the money depositing/dispensing machine  30 ,  30   b , when the collection process is interrupted. 
     In the money depositing/dispensing machine  30 ,  30   b  of the money handling system  10 ,  10   b ,  10   c  according to the present embodiment, in the collection process in which money is collected from another device (specifically, the money change machine  20 ,  20   b ) and deposited in the money depositing/dispensing machine  30 ,  30   b , when the storage cassette  40  is mounted to the cassette mounting unit  32   c , banknotes are sent from the storage cassette  40  into the money depositing/dispensing machine  30 ,  30   b . The money depositing/dispensing machine  30 ,  30   b  has the determination unit  51  for determining whether or not banknotes have been sent to the money depositing/dispensing machine  30 ,  30   b  from all the storage cassettes  40  to which banknotes have been sent from the other device when a plurality of the storage cassettes  40  are used in the collection process. 
     In the money change machine  20 ,  20   b  of the money handling system  10 ,  10   b ,  10   c  according to the present embodiment, in the collection process in which money is collected from the money change machine  20 ,  20   b  and deposited in another device (specifically, the money depositing/dispensing machine  30 ,  30   b ), banknotes are sent to the storage cassette  40  from the money change machine  20 ,  20   b  when the storage cassette  40  is mounted to the cassette mounting unit  22   c . The controller  28  outputs information on the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20 ,  20   b  when a plurality of the storage cassettes  40  are used in the collection process. Thus, the controller  28  functions as a number-of-cassettes output unit for outputting information on the number of the storage cassettes  40  to which banknotes have been sent from the money change machine  20 ,  20   b  when a plurality of the storage cassettes  40  are used in the collection process. 
     The money handling system and the money depositing/dispensing machine according to the present invention are not limited to the above-described aspects, and various modifications can be made. 
     An operation performed by the money handling system  10 ,  10   a  shown in  FIG. 1  to  FIG. 14  in the entire collection process in which all the money is collected from a plurality of the money change machines  20 ,  20   a , and deposited in the money depositing/dispensing machine  30 ,  30   a , has been described above. However, a similar operation may be performed also in an inventory process in which all the money in the store are counted. More specifically, in the inventory process in which all the money in the store is counted, all the banknotes are sent to the storage cassette  40  from the banknote handling devices  22  of a plurality of the money change machines  20 ,  20   a , and deposited from the storage cassette  40  to the banknote handling device  32  of the money depositing/dispensing machine  30 ,  30   a . The banknotes are counted by the banknote handling device  32 , and the banknotes are thereafter returned to the banknote handling devices  22  of the money change machines  20 ,  20   a  from the banknote handling device  32  by using the storage cassette  40 . In such an operation, banknotes are sent from the storage/feeding unit  32   a  to the empty storage cassette  40  mounted to the cassette mounting unit  32   c  according to a storing state of banknotes in the storage/feeding unit  32   a . Also in this case, in a case where banknotes in the storage/feeding unit  32   a  become insufficient while change fund is prepared, replenishment of banknotes can be performed merely by mounting the storage cassette  40 , and, therefore, an operation of, for example, taking out banknotes from a collection cassette (not shown) can be eliminated, and this can reduce an operator&#39;s workload and a replenishing time. 
     In the above-described inventory process, the following operation may be performed. Specifically, in the inventory process, before money dispensed from each money change machine  20 ,  20   a  is deposited in the money depositing/dispensing machine  30 ,  30   a , banknotes and coins stored in the storage/feeding unit  32   a  and the storage/feeding unit  34   a  are all sent to collection cassettes in the banknote handling device  32  and the coin handling device  34  of the money depositing/dispensing machine  30 ,  30   a . Thereafter, in a case where money dispensed from each money change machine  20 ,  20   a  is deposited in the money depositing/dispensing machine  30 ,  30   a , when the storage cassette  40  is mounted to the cassette mounting unit  32   c  in the banknote handling device  32  of the money depositing/dispensing machine  30 ,  30   a , only ten thousand yen notes among the banknotes fed out from the storage cassette  40  are stored in the collection cassette of the banknote handling device  32 , and banknotes of the other denominations are all stored in the storage/feeding unit  32   a  of the banknote handling device  32 . Coins and coin rolls among money dispensed from each money change machine  20 ,  20   a  are all stored in the storage/feeding unit  34   a  of the coin handling device  34  and the coin roll storing device  36 . After money is counted by the money depositing/dispensing machine  30 ,  30   a , the banknotes and the coins stored in the storage/feeding unit  32   a  of the banknote handling device  32  and the storage/feeding unit  34   a  of the coin handling device  34  are dispensed. At this time, the banknotes dispensed from the banknote handling device  32  are stored in the storage cassette  40 . The operator takes out the coin rolls stored in the coin roll storing device  36 . Thereafter, the operator returns the banknotes, coins, and coin rolls dispensed from the banknote handling device  32 , the coin handling device  34 , and the coin roll storing device  36 , into the initial money change machines  20 ,  20   a . In such an operation, the ten thousand yen notes dispensed from the money change machines  20 ,  20   a  are stored in the collection cassette of the money depositing/dispensing machine  30 ,  30   a , and, therefore, the ten thousand yen notes are not returned into the initial money change machines  20 ,  20   a . However, the ten thousand yen notes are not required as change fund in general, and no problem arises if the ten thousand yen notes are not returned into the initial money change machines  20 ,  20   a . When the inventory process is performed in such a manner, since the ten thousand yen notes dispensed from the money change machines  20 ,  20   a  are stored in the collection cassette of the money depositing/dispensing machine  30 ,  30   a , a state where the storage/feeding unit  32   a  is in a full state or a nearly full state and banknotes can no longer be stored in the storage/feeding unit  32   a  can be avoided as much as possible. Thus, counting of banknotes and coins collected from the money change machines  20 ,  20   a  in the money depositing/dispensing machine  30 ,  30   a  is inhibited from becoming impossible during the counting, and, therefore, the inventory process can ben ended as early as possible. 
     In the money handling system  10 ,  10   a ,  10   b ,  10   c  shown in  FIG. 1  to  FIG. 19 , the cassette mounting unit  32   c  to which the storage cassette  40  is mounted is disposed in the banknote handling device  32  of the money depositing/dispensing machine  30 ,  30   a . However, the present invention is not limited to such an aspect. In a money handling system according to a modification, instead of the cassette mounting unit being disposed in the banknote handling device of the money depositing/dispensing machine, the storage cassette may be detachably mounted to an inlet or a receptacle of the banknote handling device. In this case, when the storage cassette is mounted to the inlet or the receptacle of the banknote handling device, banknotes fed out from the storage cassette can be sent into a housing of the banknote handling device through the inlet or the receptacle, and banknotes can be sent to the storage cassette from the housing of the banknote handling device through the inlet or the receptacle. 
     In the money handling system according to a modification, a plurality of spare storage cassettes (in other words, storage cassettes used for storage) may be disposed so as to correspond to respective banknote denominations. In this case, when the storage/feeding unit of the banknote handling device is in a full state or a nearly full state, the storage cassettes corresponding to the respective denominations are sequentially mounted to the cassette mounting unit, whereby banknotes can be stored in the plurality of storage cassettes based on the respective denominations. In a case where one storage cassette is used as a spare storage cassette, when the storage/feeding unit of the banknote handling device is in a full state or a nearly full state and the storage cassette is mounted to the cassette mounting unit, banknotes of a plurality of denominations are mixedly stored in the storage cassette. 
     In the money handling system according to another modification, a plurality of cassette mounting units may be disposed in the banknote handling device of the money depositing/dispensing machine. In this case, the storage cassette for collection and the storage cassette for storage can be simultaneously mounted to the banknote handling device. In this case, in a case where the above-described entire collection process is performed, even when the storage/feeding unit in the banknote handling device of the money depositing/dispensing machine is in a full state or a nearly full state, and banknotes can no longer be stored in the storage/feeding unit, banknotes can be sent from the storage/feeding unit to the storage cassette for storage without dismounting the storage cassette for collection from the banknote handling device. 
     In the money handling system according to still another modification, the storage cassette may be used to deliver coins between the coin handling device of each money change machine disposed in the front office region and the coin handling device of the money depositing/dispensing machine disposed in the back office region. In this case, the storage cassette for storing the coins and feeding out the stored coins is detachably mounted to each of the coin handling device of each money change machine and the coin handling device of the money depositing/dispensing machine. In the money depositing/dispensing machine, coins are sent from the storage/feeding unit into the empty storage cassette mounted to the coin handling device according to a storing state of coins in the coin handling device. In this case, even when coins in the storage/feeding unit become insufficient while change fund is prepared, replenishment of coins can be performed merely by mounting the storage cassette, whereby an operation of, for example, taking out coins from the collection cassette can be eliminated, and this can reduce an operator&#39;s workload and a replenishing time. In such a money handling system, a usage determination unit disposed in the money depositing/dispensing machine may determine the usage of the storage cassette mounted to the cassette mounting unit of the coin handling device according to a storing state of coins in the storage/feeding unit of the coin handling device. Specifically, the usage determination unit may determine, as storage, the usage of the storage cassette mounted to the cassette mounting unit when coins can no longer be stored in the storage/feeding unit of the coin handling device. The same operation as performed for the usage of the storage cassette for storing banknotes as described above is performed for the usage of the storage cassette for storing coins. In such a money handling system, a determination unit is disposed for determining whether or not coins have been sent into the coin handling device of the money depositing/dispensing machine from all the storage cassettes to which coins have been sent from the coin handling device of the money change machine when a plurality of storage cassettes are used in the collection process in which coins are collected from the coin handling device of the money change machine, and deposited in the coin handling device of the money depositing/dispensing machine. Thus, whether or not coins have been sent into the coin handling device of the money depositing/dispensing machine from all the storage cassettes to which coins have been sent from the coin handling device of the money change machine when a plurality of storage cassettes are used in the collection process, is determined, and this can inhibit the operator from forgetting to mount one or more of the plurality of storage cassettes to the coin handling device of the money depositing/dispensing machine, whereby an error in calculation can be prevented from occurring in the coin handling device of the money depositing/dispensing machine.
