     SUMMARY OF INVENTION 
     Technical Problem 
     There is a limit on the number of bills that can be input into a cash inlet at one time in the cash processing device. In addition, the cash inlet is generally closed until bills input into the cash inlet are transported to a bill storage unit in the inside of the device. For this reason, in order to deposit a number of bills exceeding the number of bills that can be input into the cash inlet one time, it is considered that an additional inputs of bills into the cash inlet are repeated at timings at which the cash inlet is opened according to the end of the transport of the bills to the bill storage unit. In the method of the additional input, however, there is a concern that the time taken to perform a deposit process on cash such as bills is lengthened. 
     Therefore, the present invention takes the above-described problem into account, and an object of the present invention is to provide a novel and improved cash processing device and cash processing method capable of carrying out a deposit process of cash more efficiently. 
     Solution to Problem 
     To solve the above described problem, according to an aspect of the present invention, there is provided a cash processing device including: a cash inlet having an opening and closing member; a temporary reserving unit configured to temporarily store cash; a storage unit configured to store cash; a transport unit configured to, in a deposit process, transport cash input into the cash inlet to the temporary reserving unit in a state in which the opening and closing member is closed, and transport cash stored in the temporary reserving unit to the storage unit; and a control unit configured to control a display of a selection screen for selecting a first deposit method of performing an input of cash at one time in one transaction or a second deposit method of performing inputs of cash over a plurality of times in one transaction, and to not instruct to open the opening and closing member when the first deposit method is selected and to instruct to open the opening and closing member when the second deposit method is selected, after transport of cash input into the cash inlet to the temporary reserving unit ends and before transport of the cash stored in the temporary reserving unit to the storage unit ends. 
     The control unit may control a display of the selection screen before a first input of cash into the cash inlet in one transaction. 
     The control unit may control a display of the selection screen after cash input into the cash inlet first in one transaction is transported to the temporary reserving unit. 
     In the second deposit method, the control unit may instruct to open the opening and closing member before an instruction to transport cash stored in the temporary reserving unit to the storage unit is issued. 
     In the second deposit method, the control unit may instruct to close the opening and closing member after transport of cash stored in the temporary reserving unit to the storage unit ends. 
     In second and succeeding inputs of cash in the second deposit method, when an input of cash into the cash inlet is sensed after an instruction to open the opening and closing member is issued, the control unit may instruct to close the opening and closing member based on the sensing. 
     The cash processing device may further include a cash outlet through which a client receives cash. In a withdrawal process, the transport unit may transport cash to the cash outlet from the storage unit and update balance-in-hand of the storage unit at a timing at which the cash is ejected from the storage unit. 
     When a jam occurs in the withdrawal process, the control unit may control a display of a screen indicating cash that has been transported to the cash outlet and cash remaining in the transport unit. 
     The control unit may control a display of a screen for selecting a timing at which the balance-in-hand of the storage unit is updated from a plurality of timings including a timing at which cash is ejected from the storage unit. 
     When a jam occurs during transport of cash from the cash inlet to the temporary reserving unit in the deposit process and cash remains in the cash inlet, the control unit may instruct to open the opening and closing member. 
     When a jam occurs during transport of cash from the cash inlet to the temporary reserving unit in the deposit process, the control unit may control a display of a screen indicating cash remaining in the transport unit. 
     The screen indicating the cash remaining in the transport unit may further indicate whether or not cash remains in the cash inlet.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, referring to the appended drawings, preferred embodiments of the present invention will be described in detail. It should be noted that, in this specification and the appended drawings, structural elements that have substantially the same function and structure are denoted with the same reference numerals, and repeated explanation thereof is omitted. 
     Note that, in this specification and the drawings, structural elements that have substantially the same function and structure are sometimes distinguished from each other using different alphabets after the same reference numeral. However, when there is no need in particular to distinguish structural elements that have substantially the same function and structure, the same reference numeral alone is attached. 
     &lt;1. Overview of Bill Processing Device&gt; 
     (1-1. Internal Configuration Example of Bill Processing Device) 
     First, an internal configuration example of a bill processing device  10  according to an embodiment of the present invention that is an example of a cash processing device will be described with reference to  FIG. 1 . 
       FIG. 1  is a diagram showing the internal configuration example of the bill processing device  10  according to the embodiment of the present invention. The bill processing device  10  is installed in a branch of a financial institution or the like. The bill processing device  10  is a staff-manipulation-type terminal for conducting transactions of bills based on manipulations performed by staff such as bank tellers of financial institutions who are manipulators of the device. 
     The bill processing device  10  has a cash inlet  12 , a cash outlet  18 , a bill recognition unit  20  that is an example of a bill discriminating unit, a temporary reserving unit  22  that is an example of a temporary accumulation unit, a transport unit  24 , bill cassettes  30 A to  30 D that are examples of storage units, a bill cassette  35  with a reject storage, and a display unit  40  as shown in  FIG. 1 . 
     The cash inlet  12  is an input port of bills for a staff to input bills thereinto. In addition, the cash inlet  12  has a separation function of separating bills that are input in a bundle one by one and ejecting them. Note that the cash inlet  12  is provided with a cash inlet shutter  13  as an example of an opening and closing member to open and close an opening as shown in  FIG. 2 . 
     The cash outlet  18  is a dispensing port from which bills to be received by a staff are dispensed (withdrawn). The cash outlet  18  has an accumulation function of accumulating bills to be dispensed. The cash outlet  18  has a capacity at which 100 (the maximum accumulation number) bills can be accumulated as an example. Note that the cash outlet  18  is also provided with a cash outlet shutter  19  as an example of an opening and closing member to open and close an opening as shown in  FIG. 2 . 
       FIG. 2  shows schematic diagrams showing configuration examples of the cash inlet shutter  13  and the cash outlet shutter  19 . In  FIG. 2A , states in which the cash inlet shutter  13  and the cash outlet shutter  19  are closed are shown, and in  FIG. 2B , states in which the cash inlet shutter  13  and the cash outlet shutter  19  are opened are shown. The cash inlet shutter  13  and the cash outlet shutter  19  move to close the cash inlet  12  and the cash outlet  18 . Note that, when bills are to be transported from the cash inlet  12 , the cash inlet shutter  13  is closed, and when bills are to be transported to the cash outlet  18 , the cash outlet shutter  19  is closed. Note that, although, as an example, planar shutters are shown as the cash inlet shutter  13  and the cash outlet shutter  19  in  FIG. 2 , the cash inlet shutter  13  and the cash outlet shutter  19  may be curved shutters. 
     The bill recognition unit  20  discriminates bills passed therethrough one by one. Bills bi-directionally advance, and thus the bill recognition unit  20  can discriminate bills transported from the direction of the cash inlet  12  side and bills transported from an opposite direction thereto. Specifically, the bill recognition unit  20  discriminates denominations, genuineness (a genuine bill or a counterfeit bill), normality or defectiveness (a normal bill or a defective bill), feeding states (a normal state or an abnormal state), and the like of the bills transported through the transport unit  24 , and makes a determination of normality or a determination of rejection on passed bills. 
     Here, in the present specification, the genuine bill refers to one discriminated as a bill, and the counterfeit bill refers to one that is not discriminated as a bill. In addition, the normal bill refers to one discriminated as being proper for deposit and withdrawal among bills discriminated as genuine bills, and the defective bill refers to a one discriminated as not being proper for deposit and withdrawal among the bills discriminated as the genuine bills. In addition, the determination of rejection is made based on factors such as the counterfeit bill, the defective bill (stained, damaged, having an abnormal outer shape, etc.), the abnormal feeding (a skewed bill, double feeding, etc.), or the like. In addition, rejected bills may include bills that are not treated as bills to be withdrawn (for example, a two-thousand-yen bill or a five-thousand-yen bill), or foreign bills. 
     The temporary reserving unit  22  has both functions of separation and accumulation of bills. For example, the temporary reserving unit  22  temporarily accumulates (stores) bills that are separated from the cash inlet  12  during a deposit process and discriminated as being normal by the bill recognition unit  20 . Bills that are accumulated in the temporary reserving unit  22  are ejected when transactions are concluded, such as when calculation of the deposited bills with respect to accounts or the like is confirmed, pass through the bill recognition unit  20 , and then are transported to the bill cassettes  30 A to  30 D, and the like. Note that the temporary reserving unit  22  may adopt an accumulation type in which bills are sequentially piled up and accumulated, or a drum type in which bills are sequentially rolled up and stored. 
     The transport unit  24  includes a transport path, a transport roller that transports bills, and a driving mechanism that drives the transport roller to transport bills one by one. The driving mechanism drives the transport roller as, for example, a DC servo motor, a pulse motor, or the like rotates. The transport unit  24  is controlled by a control unit to be described below, and transports bills to a target transport destination. 
     The bill cassettes  30 A to  30 D are bill storage units in which bills can be stored according to denominations, the bill cassettes  30 A to  30 D having both functions of accumulation and separation of bills. In addition, the bill cassettes  30 A to  30 D may include a plurality of bill cassettes for the same denomination. For example, the bill cassettes  30 A and  30 C may be bill cassettes for ten-thousand-yen bills, and the bill cassettes  30 B and  30 D may be bill cassettes for one-thousand-yen bills. In addition, the bill cassettes  30 A to  30 D are configured to be attachable to and detachable from the bill processing device  10 , and by unfixing an installed bill cassette  30  from the bill processing device  10  and installing a bill cassette  30  in which a sufficient amount of bills are stored in the bill processing device  10 , the bill processing device  10  can be loaded with the bills. 
     The bill cassette  35  with the reject storage (hereinafter referred to also as a bill cassette  35 ) is configured to be attachable to and detachable from the bill processing device  10 , and collection and replenishment of bills are possible by replacing an installed bill cassette  35  with another bill cassette  35 . In addition, the bill cassette  35  is provided with a bill storage  36  on its upper side and a reject storage  37  on its lower side (the bottom). 
     The bill storage  36  has an accumulation function of accumulating bills and a separation function of ejecting bills one by one. In addition, the bill storage  36  can accumulate bills separated from each of the bill cassettes  30 A to  30 D and can collect bills at the time of a cassette counting-type collection. In addition, the bill storage  36  can eject bills accumulated in the bill storage  36  and replenish the bill cassettes  30 A to  30 D with the bills in a cassette counting-type replenishment. 
     The reject storage  37  has only an accumulation function of accumulating bills therein. The reject storage  37  is a bill storage unit for accumulating bills that are discriminated as being abnormal (rejected bills) by the bill recognition unit  20  (a determination of rejection). 
     The display unit  40  displays a menu screen or a processing result screen. The display unit  40  is realized by, for example, a cathode ray tube (CRT) display device, a liquid crystal display (LCD) device, or an organic light emitting diode (OLED) device. 
     In addition, the bill processing device  10  has a manipulation unit (not illustrated) that can be manipulated by a staff. The bill processing device  10  performs deposit processes, withdrawal processes, and the like that correspond to transactions of deposit and withdrawal as a staff manipulates the manipulation unit. Note that the bill processing device  10  may perform processes based on manipulations by a staff on a reception terminal connected to the bill processing device  10  instead of the manipulation unit. 
     (1-2. Basic Processes of Bill Processing Device) 
     The internal configuration example of the bill processing device  10  according to the embodiment of the present invention has been described above with reference to  FIGS. 1 and 2 . Next, a deposit process, a withdrawal process, a replenishment process, and a collection process executed as basic process by the bill processing device  10  will be described. 
     (Deposit Process) 
     A deposit process is a process of accumulating bills input into the cash inlet  12  at the inside of the bill processing device  10 , and is broadly divided into a counting process and a storing process. In the counting process, first, bills input into the cash inlet  12  are separated and ejected one by one, and the ejected bills are transported to the bill recognition unit  20  by the transport unit  24 . Next, the bill recognition unit  20  discriminates the bills, and bills that are discriminated as being normal as a result of the discrimination are counted, transported to the temporary reserving unit  22 , and accumulated therein. Thereafter, if the amount of the deposit is confirmed, the process proceeds to the storing process. 
     On the other hand, bills that are discriminated as being abnormal (rejected bills) as a result of the discrimination by the bill recognition unit  20  are accumulated in the cash outlet  18 . The bills accumulated in the cash outlet  18  can undergo re-discrimination by the bill recognition unit  20  when a staff inputs the bills into the cash inlet  12  again. 
     In the storing process, first, bills are separated one by one from the temporary reserving unit  22 , and the separated bills are transported to the bill recognition unit  20 . Next, bills that are discriminated as being normal as a result of the discrimination by the bill recognition unit  20  are accumulated in the bill cassettes  30 A to  30 D that correspond to their denominations. On the other hand, bills that are discriminated as being abnormal as a result of the discrimination by the bill recognition unit  20  like bills that cause feeding abnormality such as a stained bill, a folded bill, or a skewed bill, are accumulated in the reject storage  37  of the bill cassette  35 . 
     On the other hand, when an instruction to return (cancel a deposited bill is issued before confirmation of a deposit amount, the process transitions to a return process. In the return process, first, bills are separated one by one from the temporary reserving unit  22 , and the separated bills are transported to the bill recognition unit  20 . Then, all the bills are accumulated in the cash outlet  18  regardless of whether the result of the discrimination by the bill recognition unit  20  is normal or abnormal. 
     (Withdrawal Process) 
     A withdrawal process is a process of accumulating bills of the bill cassettes  30 A to  30 D in the cash outlet  18 . In the withdrawal process, first, bills are separated one by one and ejected from the bill cassettes  30 A to  30 D according to a designated amount, and the ejected bills are transported to the bill recognition unit  20  by the transport unit  24 . Next, the bill recognition unit  20  discriminates the bills, and bills that are discriminated as being normal as a result of the discrimination are accumulated in the cash outlet  18 . Specifically, bills are accumulated (collected) in the cash outlet  18  according to, for example, the denominations or the numbers of normal bills to be withdrawn. On the other hand, bills that are discriminated as being abnormal as a result of the discrimination, i.e., bills that are not suitable for being provided to clients, are accumulated in the reject storage  37  of the bill cassette  35 . 
     (Replenishment Process) 
     A replenishment process is a process of replenishing the bill processing device  10  with bills. As specific replenishing methods, a cash-inlet replenishment, a cassette replacement-type replenishment, and a cassette counting-type replenishment are possible in the bill processing device  10 . The respective replenishing methods will be described below. 
     The cash-inlet replenishment is similar to the operation of the deposit process described above. For example, bills that are ejected from the cash inlet  12  and discriminated as being normal as a result of discrimination by the bill recognition unit  20  are drawn out to the temporary reserving unit  22  and then accumulated in the bill cassettes  30 A to  30 D according to their denominations. On the other hand, bills that are discriminated as being abnormal as a result of discrimination are accumulated in the cash outlet  18 . 
     The cassette replacement-type replenishment uses the attachable and detachable bill cassettes  30 A to  30 D to replace any of the bill cassettes  30 A to  30 D that is installed in advance with a bill cassette that is loaded with bills in advance. Thereby, bills are replenished. Note that, in the cassette replacement-type replenishment, it is necessary for an operator to manually register the denominations and the number of replenished bills. 
     In the cassette counting-type replenishment, first, bills are loaded in the bill storage  36  of the bill cassette  35  in advance, and the bill cassette  35  is set in the bill processing device  10 . Next, bills that are ejected from the bill storage  36  and discriminated as being normal as a result of discrimination by the bill recognition unit  20  are accumulated in the bill cassettes  30 A to  30 D that correspond to their denominations. On the other hand, bills that are discriminated as being abnormal as a result of the discrimination are accumulated in the reject storage  37 . Note that, since a counting process is executed by the bill recognition unit  20  in the cassette counting-type replenishment, it is not necessary for an operator to manually register the denominations and the number of replenished bills. 
     (Collection Process) 
     The collection process is a process of collecting bills that are in the bill processing device  10 . As specific collection methods, a cash-outlet collection, a cassette replacement-type collection, and a cassette counting-type collection are possible in the bill processing device  10 . The respective collection methods will be described below. 
     The cash-outlet collection is similar to the operation of the withdrawal process described above. For example, bills that are ejected from the bill cassettes  30 A to  30 D that are collection objects and discriminated as being normal as a result of discrimination by the bill recognition unit  20  are accumulated in the cash outlet  18 . On the other hand, bills that are discriminated as being abnormal as a result of the discrimination are accumulated in the reject storage  37 . Then, performing discrimination with respect to all the bills accumulated in the bill cassettes  30 A to  30 D that are collection objects, a staff can collect the bills that have been determined to be normal from the cash outlet  18 . In addition, the staff can collect the bills that have been determined to be abnormal from the reject storage  37 . 
     In the cassette replacement-type collection, bills are collected by unfixing a predetermined bill cassette among the bill cassettes  30 A to  30 D from the bill processing device  10 . Note that, in the cassette replacement-type collection, it is necessary for an operator to take out bills from the unfixed bill cassettes  30 A to  30 D and to manually count the denominations and the number of the collected bills. 
     In the cassette counting-type collection, bills that are ejected from a bill cassette that is a collection object among the bill cassettes  30 A to  30 D and discriminated as being normal as a result of discrimination by the bill recognition unit  20  are accumulated in the bill storage  36  of the bill cassette  35 . On the other hand, bills that are discriminated as being abnormal as a result of the discrimination are accumulated in the reject storage  37 . Thereafter, a staff can collect the bills determined to be normal and the bills determined to be abnormal by unfixing only the bill cassette  35  from the bill processing device  10 . In addition, because a counting process is executed by the bill recognition unit  20  in the cassette counting-type collection, it is not necessary for an operator to manually count the denominations and the number of the collected bills. 
     (1-3. Background of Embodiment of Present Invention) 
     In a general bill processing device, it is not possible to additionally input bills into a cash inlet because a cash inlet shutter is closed during a deposit process. In addition, although rejected bills are accumulated in a cash outlet during a deposit process, it is not possible to take out the rejected bills during the deposit process. In other words, it is not possible to additionally input bills or to take out rejected bills until a counting process of a bill input into the cash inlet (included in the deposit process) is completed. For this reason, it takes a long period of time to deposit a large number of bills. 
     On the other hand, an additional input of bills into a cash inlet may be received during a storing process by opening the cash inlet shutter at all times after all bills deposited from the cash inlet are transported to the temporary reserving unit. According to this configuration, it is expected to shorten a time taken to deposit bills of which the number is equal to or greater than the number of bills that can be input into the cash inlet at one time. 
     However, in the method described above, since the cash inlet shutter is uniformly opened even when no additional input of a bill is performed, there is a concern that a foreign substance is introduced into the cash inlet due to unnecessary opening of the cash inlet shutter. 
     Therefore, the bill processing device  10  according to an embodiment of the present invention has been created focusing on the above circumstance. The bill processing device  10  according to the embodiment of the present invention can realize efficiency of bill deposit processes and improvement in the problem of foreign substances being introduced into the cash inlet. A configuration and an operation of the bill processing device  10  according to the embodiment of the present invention will be sequentially described in detail. 
     &lt;2. Functional Configuration of Bill Processing Device&gt; 
       FIG. 3  is a functional block diagram showing a configuration of the bill processing device  10  according to the embodiment of the present invention. As shown in  FIG. 3 , the bill processing device  10  is provided with the cash inlet shutter  13 , the cash outlet shutter  19 , the transport unit  24 , the display unit  40 , a manipulation unit  42 , a control unit  70 , a memory unit  80 , and a sensing unit  82 . The cash inlet shutter  13 , the cash outlet shutter  19 , the transport unit  24 , the display unit  40 , and the manipulation unit  42  are as described with reference to  FIGS. 1 and 2 . 
     The control unit  70  controls overall operations of the bill processing device  10 . For example, the control unit  70  controls the basic processes such as the deposit process, the withdrawal process, the replenishment process, and the collection process described above according to manipulations of a staff using the manipulation unit  42 . Specifically, the control unit  70  controls the transport of bills by the transport unit  24  and the opening and closing operations of the cash inlet shutter  13  and the cash outlet shutter  19  for the execution of the basic processes. In addition, the control unit  70  controls a display of various screens to cause the various screens to be displayed on the display unit  40 . For example, the control unit  70  controls display of selection screens (a deposit method setting screen and a deposit selection screen) for selecting a normal deposit in which an input of bills is performed once in one transaction (a first deposit method) or a mass deposit in which inputs of bills are performed over a plurality of times in one transaction (a second deposit method) (details of the methods will be described later). Then, the control unit  70  controls the deposit process according to a deposit method selected on the selection screen. 
     The memory unit  80  memorizes a program and the like by which the bill processing device  10  is operated. In addition, the memory unit  80  can memorize discrimination results of the bill recognition unit  20 . 
     The sensing unit  82  has, for example, an optical sensor and the like to sense various states. For example, the sensing unit  82  detects accumulation states of bills of the cash inlet  12  and the cash outlet  18  (the number of accumulated bills and whether or not a bill has been taken out). In addition, the sensing unit  82  can sense transport states of bills, ejection of bills from the bill cassettes  30 , and the like. 
     Note that the functions of the control unit  70  and the memory unit  80  described above may be realized as a hardware configuration constituted by a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and the like. The CPU has an arithmetic operation function and a control function, and controls overall operations of the bill processing device  10  according to various programs. The ROM memorizes a program used by the CPU, arithmetic operation parameters, and the like. The RAM temporarily memorizes a program used in execution of the CPU, parameters that appropriately change in the execution, and the like. 
     The bill processing device  10  described above can perform a variety of operations based on the control of the control unit  70 . A plurality of operations that can be executed by the bill processing device  10  will be sequentially described below in detail. 
     &lt;3. First Operation&gt; 
     In a first operation, the control unit  70  controls the display of the deposit method setting screen prior to a deposit process, and when a normal deposit is selected, the cash inlet shutter  13  is not opened after a deposited bill is transported to the temporary reserving unit  22 , and when a mass deposit is selected, the cash inlet shutter  13  is opened after deposited bills are transported to the temporary reserving unit  22 . According to this configuration, when the normal deposit is selected, i.e., when no additional input of bills is performed, the cash inlet shutter  13  is not opened, which can prevent a foreign substance from being introduced into the cash inlet  12 . On the other hand, when the mass deposit is selected, additional input of bills into the cash inlet  12  can be performed in parallel with a storing process due to the opening of the cash inlet shutter  13 , and therefore, efficiency in the deposit process can be attained. The first operation will be described below in more detail with reference to  FIGS. 4 to 7 . 
     (Normal Deposit) 
       FIG. 4  is an illustrative diagram showing an operation example of a normal deposit. As shown in  FIG. 4 , first, the display unit  40  displays the deposit method setting screen based on the display control of the control unit  70  (S 102  and S 104 ). The deposit method setting screen includes, for example, a normal deposit selection button  51 , a mass deposit selection button  52 , an OK button  53 , and a cancel button  54  as shown in  FIG. 5 . When the OK button  53  is selected in a state in which the normal deposit selection button  51  is selected, a deposit method is set to normal deposit, and when the OK button  53  is selected in a state in which the mass deposit selection button  52  is selected, the deposit method is set to mass deposit. When the cancel button  54  is selected, current settings are maintained. Here, description will be continued on the assumption that a staff selects the normal deposit selection button  51  (S 106 ) as shown in  FIG. 4  and thus the deposit method is set to normal deposit. 
     When a staff selects a deposit method, the control unit  70  instructs to open the cash inlet shutter  13  (S 108 ), then the cash inlet shutter  13  is opened based on the instruction (S 110 ), and a notification of a shutter opening completion is output to the control unit  70  (S 116 ). In addition, the display unit  40  displays a bill input inducing screen to induce an input of bills by the staff based on the display control of the control unit  70  (S 112  and S 114 ). 
     Thereafter, when the staff inputs bills into the cash inlet  12  (S 118 ), the sensing unit  82  notifies the control unit  70  of a sensing of the input of the bills (S 120 ). The control unit  70  receives the notification and instructs to close the cash inlet shutter  13  (S 122 ), then the cash inlet shutter  13  is closed based on the instruction (S 124 ), and then a notification of a shutter closing completion is output to the control unit  70  (S 126 ). 
     Next, the control unit  70  instructs the transport unit  24  to perform a counting process of the deposited bills (S 128 ), and the transport unit  24  starts the counting process based on the instruction (S 130 ). Through this counting process, the bills input into the cash inlet  12  are transported to the temporary reserving unit  22 . In addition, the display unit  40  displays a deposit counting waiting screen indicating that the counting process of the deposited bills is being performed based on the display control of the control unit  70  (S 132  and S 134 ). Then, the transport unit  24  outputs a notification of a counting end to the control unit  70  when the counting process ends (S 136 ). 
     Next, the display unit  40  displays a deposit information screen that includes the number of bills obtained in the counting process based on the display control of the control unit  70  (S 138  and S 140 ). Thereafter, the control unit  70  instructs the transport unit  24  to perform a storing process of bills (S 142 ), and the transport unit  24  starts the storing process based on the instruction (S 144 ). In addition, the display unit  40  displays a storage waiting screen indicating that the deposited bills are undergoing the storing process based on the display control of the control unit  70  (S 146  and S 148 ). Then, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 150 ). Thereafter, the display unit  40  displays a deposit completion screen indicating the completion of the deposit process based on the display control of the control unit  70  (S 154 ), and thereby the normal deposit ends. 
     In the first operation, a staff can select a deposit method through the display of the deposit method setting screen as described above. In addition, in the normal deposit, the cash inlet shutter  13  is not opened and its closed state is maintained after the counting process ends. For this reason, when the number of bills to be deposited is equal to or fewer than the number of bills that can be input at one time, the staff selects the normal deposit on the deposit method setting screen to maintain the closing of the cash inlet shutter  13  after the counting process, which can prevent a foreign substance from being introduced into the cash inlet  12 . 
     (Mass Deposit) 
       FIGS. 6 and 7  are illustrative diagrams showing an operation example of a mass deposit. As shown in  FIG. 6 , first, the display unit  40  displays the deposit method setting screen based on the display control of the control unit  70  (S 102  and S 104 ). Here, description will be continued on the assumption that a staff selects the mass deposit selection button  52  on the deposit method setting screen (S 107 ), and thereby the deposit method is set to mass deposit as shown in  FIG. 6 . Note that, since the processes of S 108  to S 140  of the mass deposit are the same as the processes of S 108  to S 140  of the normal deposit, detailed description will be omitted here. 
     After causing the display unit  40  to display the deposit information screen in S 140 , the control unit  70  instructs to open the cash inlet shutter  13  (S 156 ), then the cash inlet shutter  13  is opened based on the instruction (S 158 ), and a notification of a shutter opening completion is output to the control unit  70  (S 160 ). Furthermore, the control unit  70  instructs the transport unit  24  to perform a storing process of bills (S 162 ), and the transport unit  24  starts the storing process based on the instruction (S 164 ). In addition, the display unit  40  displays an input inducing/storage waiting screen indicating that the deposited bills are undergoing the storing process and inducing the staff to input bills based on the display control of the control unit  70  (S 166  and S 168 ). 
     Thereafter, the staff additionally inputs bills into the cash inlet  12  (S 202 ) as shown in  FIG. 7 . Then, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 204 ). Upon receiving the notification of storage end, the control unit  70  outputs a request for checking whether or not there is a remaining bill in the cash inlet  12  to the sensing unit  82  (S 206 ), and the sensing unit  82  notifies the control unit  70  about the fact that there is a bill (S 208 ). 
     Then, the control unit  70  instructs to close the cash inlet shutter  13  (S 210 ), then the cash inlet shutter  13  is closed based on the instruction (S 212 ), and a notification of a shutter closing completion is output to the control unit  70  (S 214 ). 
     Next, the control unit  70  instructs the transport unit  24  to perform a counting process on the deposited bill (S 216 ), and then the transport unit  24  starts the counting process based on the instruction (S 218 ). Through this counting process, the bills input into the cash inlet  12  are transported to the temporary reserving unit  22 . In addition, the display unit  40  displays the deposit counting waiting screen indicating that the deposited bills are undergoing the counting process based on the display control of the control unit  70  (S 220  and S 222 ). Then, the transport unit  24  outputs a notification of a counting completion to the control unit  70  when the counting process ends (S 224 ). 
     Next, the display unit  40  displays the deposit information screen that includes the number of bills obtained in the counting process of S 218  and the total number of bills obtained in the previous counting processes including S 218  based on the display control of the control unit  70  (S 226  and S 228 ). 
     Next, the control unit  70  instructs to open the cash inlet shutter  13  upon receiving, for example, a confirmation manipulation from the staff on the input information screen (S 230 ), then the cash inlet shutter  13  is opened based on the instruction (S 232 ), and then a notification of a shutter opening completion is output the control unit  70  (S 234 ). Furthermore, the control unit  70  instructs the transport unit  24  to perform a storing process of bills (S 236 ), and then the transport unit  24  starts the storing process based on the instruction (S 238 ). In addition, the display unit  40  displays an input inducing/storage waiting screen indicating that the deposited bills are undergoing the storing process and inducing the staff to input bills based on the display control of the control unit  70  (S 240  and S 242 ). 
     Thereafter, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 244 ). Upon receiving the notification of the storage end, the control unit  70  outputs a request for checking whether or not there is a remaining bill in the cash inlet  12  to the sensing unit  82  (S 246 ), and the sensing unit  82  notifies the control unit  70  about the fact that there are no bills (S 248 ). 
     Then, the control unit  70  instructs to close the cash inlet shutter  13  (S 250 ), then the cash inlet shutter  13  is closed based on the instruction (S 252 ), and then a notification of a shutter closing completion is output to the control unit  70  (S 254 ). Thereafter, the display unit  40  displays a deposit completion screen indicating the completion of the deposit process based on the display control of the control unit  70  (S 256  and S 258 ), and thereby the mass deposit ends. 
     As described above, in the first operation, a staff can select a deposit method through the display of the deposit method setting screen. In addition, in the mass deposit, since the cash inlet shutter  13  is opened after a counting process ends, an additional input of bills into the cash inlet  12  can be performed in parallel with a storing process. As a result, a time taken to perform a deposit process on bills of which the number is greater than the number of bills that can be input into the cash inlet  12  at one time can be shortened. 
     Note that, although the example in which the control unit  70  instructs to open the cash inlet shutter  13  prior to the instruction of the storing processes shown in S 162  and S 236  has been described in the above description, the instruction to open the cash inlet shutter  13  may be issued after an instruction of the storing process. According to this configuration, the timing of the notification of the storage end shown in S 204  and S 244  becomes earlier, and therefore, an overall time taken for the deposit process is expected to be further shorten. 
     In addition, although the example in which the control unit  70  ascertains the completion of a bill input based on the notification from the sensing unit  82  that there are no bills shown in S 248  and the deposit process is thereafter completed without opening the cash inlet shutter  13  has been described above, the control unit  70  may ascertain the completion of a bill input based on an input completion manipulation by a staff and thereby complete the deposit process. 
     (Modified Example of Mass Deposit) 
     Next, a modified example of a mass deposit according to the first operation will be described. In the mass deposit described with reference to  FIGS. 6 and 7 , the cash inlet shutter  13  is closed after the storing process of bills ends as shown in S 212  and S 252 . On the other hand, according to the modified example of the mass deposit, when an input of bills is sensed, the cash inlet shutter  13  is closed based on the sensing even before a storing process on the bills ends. According to this configuration, since the time during which the cash inlet shutter  13  is opened is reduced, it is possible to further suppress introduction of a foreign substance into the cash inlet  12 . The modified example of the mass deposit according to the first operation will be described in detail with reference to  FIG. 8 . 
       FIG. 8  is an illustrative diagram showing an operation example of the modified example of a mass deposit. Since processes up to the input of bills of S 202  are the same as in the process of a mass deposit described with reference  FIG. 6 , detailed description will be omitted here. 
     In the modified example of the mass deposit, when a staff inputs bills into the cash inlet  12  (S 202 ), the sensing unit  82  notifies the control unit  70  of sensing of the input of the bills (S 260 ) as shown in  FIG. 8 . The control unit  70  receives the notification and instructs a closing of the cash inlet shutter  13  (S 262 ), then the cash inlet shutter  13  is closed based on the instruction (S 264 ), and then a notification of a shutter closing completion is output the control unit  70  (S 266 ). 
     Thereafter, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 268 ). Upon receiving the notification of the storage end, the control unit  70  instructs the transport unit  24  to perform a counting process on the deposited bills (S 270 ), and the transport unit  24  starts the counting process based on the instruction (S 272 ). Through this counting process, the bills input into the cash inlet  12  are transported to the temporary reserving unit  22 . In addition, the display unit  40  displays the deposit counting waiting screen indicating that the deposited bills are undergoing the counting process based on the display control of the control unit  70  (S 274  and S 276 ). Then, the transport unit  24  outputs a notification of a counting end to the control unit  70  when the counting process ends (S 278 ). 
     Next, the display unit  40  displays the deposit information screen that includes the number of bills obtained in the counting process of S 272  and the total number of bills obtained in the previous counting processes performed including S 272  based on the display control of the control unit  70  (S 280  and S 282 ). 
     Next, the control unit  70  receives, for example, a confirmation manipulation by a staff on the deposit information screen, and instructs to open the cash inlet shutter  13  (S 284 ), then the cash inlet shutter  13  is opened based on the instruction (S 285 ), and then a notification of a shutter opening completion is output to the control unit  70  (S 286 ). Further, the control unit  70  instructs the transport unit  24  to perform a storing process of the bills (S 287 ), and the transport unit  24  starts the storing process based on the instruction (S 288 ). In addition, the display unit  40  displays an input inducing/storage waiting screen indicating that the deposited bills are undergoing the storing process and inducing the staff to input bills based on the display control of the control unit  70  (S 289  and S 290 ). 
     Thereafter, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 291 ). Then, because the control unit  70  has not received a notification of a sensing of the input of bills up to this point of time, the control unit determines that there is no additional input of bills and instructs to close the cash inlet shutter  13  (S 292 ). The cash inlet shutter  13  is closed based on the instruction (S 293 ), and a notification of a shutter closing completion is output to the control unit  70  (S 294 ). Thereafter, the display unit  40  displays the deposit completion screen indicating the completion of the deposit process based on the display control of the control unit  70  (S 295  and S 296 ), and thereby the mass deposit according to the modified example ends. 
     As described above, according to the modified example of the mass deposit, when the input of bills is sensed, the cash inlet shutter  13  is closed based on the sensing even before the storing process of bills ends, as shown in S 260  and S 262 . According to this configuration, the time during which the cash inlet shutter  13  is opened is reduced, and thus it is possible to further suppress introduction of a foreign substance into the cash inlet  12 . 
     Note that, although the example in which the control unit  70  determines that there is no additional input of bills based on the fact that the control unit has received no notification of an input of bills until S 291  and the deposit process is completed without opening the cash inlet shutter  13  has been described above, the control unit  70  may ascertain the completion of an input of bills based on an input completion manipulation by a staff, and then the deposit process may be completed. 
     &lt;4. Second Operation&gt; 
     The first operation that can be performed by the bill processing device  10  has been described above. Next, a second operation that can be performed by the bill processing device  10  will be described. In the second operation, the control unit  70  controls a display of the deposit selection screen for selecting whether or not bills are to be additionally input each time a counting process ends, opens the cash inlet shutter  13  when an additional input is selected, and maintains the closed cash inlet shutter  13  when an end is selected. According to this configuration, the cash inlet shutter  13  is not opened after the final input of a bill, and thus it is possible to prevent a foreign substance from being introduced into the cash inlet  12 . The second operation will be described below in detail with reference to  FIGS. 9 to 11 . 
     (Normal Deposit) 
       FIG. 9  is an illustrative diagram showing an operation example of a normal deposit. As shown in  FIG. 9 , when a staff requests a start of a deposit from the bill processing device  10  (S 103 ), the control unit  70  instructs to open the cash inlet shutter  13  (S 108 ), and the cash inlet shutter  13  is opened based on the instruction (S 110 ). Thereafter, the processes of S 112  to S 136  described with reference to  FIG. 4  are performed. 
     Then, when counting of the deposited bills ends (S 136 ), the display unit  40  displays a deposit information/deposit selection screen that includes the number of bills obtained in the counting process and a selection button for selecting whether or not an additional input is to be performed based on the display control of the control unit  70  (S 137  and S 139 ). Here, a specific example of the deposit information/deposit selection screen will be described with reference to  FIG. 10 . 
       FIG. 10  is an illustrative diagram showing a specific example of the deposit information/deposit selection screen. As shown in  FIG. 10 , the deposit information/deposit selection screen includes a deposit information area  62  in which the number of deposited bills obtained through the counting process is indicated, an additional input selection button  64 , and an end button  66 . The additional input selection button  64  is selected when a staff desires an additional input of bills, and the end button  66  is selected when a staff desires an end of the deposit. Here, description will be continued on the assumption that a staff selects the end button  66  as shown in  FIG. 9  (S 141 ). 
     When the end button  66  is selected on the deposit information/deposit selection screen (S 141 ), the control unit  70  instructs the transport unit  24  to perform a storing process of bills (S 142 ), and the transport unit  24  starts the storing process based on the instruction (S 144 ). In addition, the display unit  40  displays the storage waiting screen indicating that the deposited bills are undergoing the storing process based on the display control of the control unit  70  (S 146  and S 148 ). Then, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 150 ). Thereafter, the display unit  40  displays the deposit completion screen indicating the completion of the deposit process based on the display control of the control unit  70  (S 152  and S 154 ), and thereby the deposit process ends. 
     As described above, in the second operation, the deposit information/deposit selection screen for selecting whether or not bills are to be additionally input after the counting process ends is displayed. Then, when a staff selects the end button  66  on the deposit information/deposit selection screen displayed first, the deposit process ends with no additional input of bills. In other words, the selection of the end button  66  on the deposit information/deposit selection screen displayed first can also mean selection of a normal deposit. According to this second operation, the cash inlet shutter  13  is maintained to be closed after a counting process in the normal deposit as in the first operation, and therefore, it is possible to prevent a foreign substance from being introduced into the cash inlet  12 . 
     (Mass Deposit) 
       FIG. 11  is an illustrative diagram showing an operation example of a mass deposit. Note that succeeding processes from S 139  described in  FIG. 9  as the process of the normal deposit are shown in  FIG. 11 , and preceding processes before S 139  of a mass deposit are the same as those in the process of the normal deposit described in  FIG. 9 . 
     As shown in  FIG. 11 , when a staff selects the additional input selection button  64  on the deposit information/deposit selection screen (S 143 ), the control unit  70  instructs to open the cash inlet shutter  13  (S 156 ), and then the cash inlet shutter  13  is opened based on the instruction (S 158 ). Thereafter, the processes from S 160  to S 224  described with reference to  FIGS. 6 and 7  are performed. 
     Then, when the counting of deposited bills ends (S 224 ), the display unit  40  displays the deposit information/deposit selection screen that includes deposit information and a selection button for selecting whether or not an additional input is to be performed based on the display control of the control unit  70  (S 302  and S 304 ). Note that the deposit information may include the number of bills obtained from the counting process of S 218  and the total number of bills obtained from the previous counting processes including S 218 . 
     Thereafter, when the end button  66  is selected on the deposit information/deposit selection screen (S 306 ), the control unit  70  instructs the transport unit  24  to perform a storing process on the bills (S 308 ), and then the transport unit  24  starts the storing process based on the instruction (S 310 ). In addition, the display unit  40  displays the storage waiting screen indicating that the deposited bills are undergoing the storing process based on the display control of the control unit  70  (S 312  and S 314 ). Then, the transport unit  24  outputs a notification of a storage end to the control unit  70  when the storing process ends (S 316 ). Thereafter, the display unit  40  displays the deposit completion screen indicating the completion of the deposit process based on the display control of the control unit  70  (S 318  and S 320 ), and thereby the deposit process ends. 
     As described above, in the second operation, the deposit information/deposit selection screen for selecting whether or not an additional input of bills is to be performed is displayed each time a counting process ends. Then, when a staff selects the additional input selection button  64  on the deposit information/deposit selection screen, the cash inlet shutter  13  is opened, and thus an additional input of bills can be performed. In other words, the selection of the additional input selection button  64  on the deposit information/deposit selection screen can also mean selection of a mass deposit. According to this second operation, when the end button  66  is selected on the deposit information/deposit selection screen, the cash inlet shutter  13  is maintained to be closed after the final input of bills (S 202 ) of the mass deposit, and thereby it is possible to prevent a foreign substance from being introduced into the cash inlet  12 . 
     &lt;5. Third Operation&gt; 
     The second operation that can be performed by the bill processing device  10  has been described above. Next, a third operation that can be performed by the bill processing device  10  will be described. The third operation is an operation relating to a withdrawal process. In particular, the third operation relates to a setting of an update timing of balance-in-hand in the bill processing device  10  in a withdrawal process and a withdrawal process according to the setting. According to this third operation, a workload of a staff arising from the occurrence of a jam can be reduced as will be described below in detail. A withdrawal setting screen for setting a balance-in-hand update timing will be described, and then the flow of a process at each balance-in-hand update timing will be described below. 
     (Withdrawal Setting Screen) 
       FIG. 12  is an illustrative diagram showing a specific example of the withdrawal setting screen. As shown in  FIG. 12 , the withdrawal setting screen includes a bill discharge time selection button  71 , a bill ejection time selection button  72 , an OK button  73 , and a cancel button  74 . 
     The bill discharge time selection button  71  is a selection button for setting a balance-in-hand update timing to a bill discharge time in a withdrawal process. The bill discharge time may be a timing at which the cash outlet shutter  19  is opened. Although an example in which a timing at which the cash outlet shutter  19  is opened is a bill discharge time will be described below, a bill discharge time may be a timing at which bills have passed through the bill recognition unit  20  or a timing at which bills have been transported to the cash outlet  18 . The bill ejection time selection button  72  is a selection button for setting a balance-in-hand update timing to a bill ejection time in a withdrawal process. The bill ejection time may be a timing at which bills are ejected from a bill cassette  30 . The OK button  73  is a selection button for confirming a withdrawal setting, and the cancel button  74  is a selection button for maintaining a current withdrawal setting. 
     A staff can set a balance-in-hand update timing in a withdrawal process by manipulating the withdrawal setting screen described above. 
     (Balance-in-Hand Update Timing: Bill Discharge Time) 
     Next, a withdrawal process performed when a balance-in-hand update timing is set to a bill discharge time will be described with reference to  FIG. 13 . 
       FIG. 13  is an illustrative diagram showing the withdrawal process performed when a balance-in-hand update timing is set to a bill discharge time. When a staff requests a start of a withdrawal from the bill processing device  10  (S 402 ), the control unit  70  instructs the transport unit  24  to eject bills in a designated amount from the bill cassettes  30  (S 404 ) as shown in  FIG. 13 . The transport unit  24  starts the ejection of bills from the bill cassettes  30  based on the instruction (S 406 ), and transports the ejected bills to the cash outlet  18  (S 408 ). Then, when a jam occurs before all the bills in the designated amount arrive at the cash outlet  18  (S 410 ), a notification of a failure state is output to the control unit  70  in a state in which the bills remain in the transport unit  24  and the cash outlet  18  (S 412 ). 
     Upon receiving the notification of the failure state, the control unit  70  requests checking of whether or not there is a remaining bill to be removed inside the bill processing device  10  from the sensing unit  82  (S 414 ), and the sensing unit  82  responds with presence or absence and the position of the remaining bill to be removed inside the bill processing device  10  (S 416 ). Note that the remaining bill to be removed inside the bill processing device  10  includes a bill remaining in the transport unit  24  and a bill that has been transported to the cash outlet  18 . 
     Then, when there is a remaining bill (yes in S 418 ), the display unit  40  displays a removal instruction screen instructing to remove the remaining bill based on the control of the control unit  70  (S 420  and S 422 ). Upon receiving the display of the removal instruction screen, the staff removes the bills remaining inside the bill processing device  10  (S 424 ). 
     Here, in the present example in which a balance-in-hand update timing is a bill discharge time, since a balance-in-hand update process is not performed in the stage of S 424  in which the staff removes the remaining bill, the remaining bills are bills that the bill processing device  10  recognizes as being present inside the device. However, manually returning the remaining bills into the inside of the bill processing device  10  is mechanically difficult, and if the remaining bills are returned to the inside of the bill processing device  10  using the transport function, the balance-in-hand managed in the device further increases, and thus the staff separately keeps the remaining bills removed in S 424  in a different place from the bill cassettes  30  of the bill processing device  10  (S 428 ). Thereafter, the staff requests a start of a withdrawal from the bill processing device  10  again (S 430 ). 
     As described above, when a balance-in-hand update timing is a bill discharge time, a staff separately keeps remaining bills caused by the occurrence of a jam in a different place from the bill cassettes  30  of the bill processing device  10 . Then, the separately kept remaining bills are used in a balancing process. The balancing process is a process of adding the actual number of bills inside the bill processing device  10  and the number of separately kept remaining bills together and checking whether or not the sum matches the balance-in-hand managed by the bill processing device  10 . 
     However, since the remaining bills are separately kept in a different place from the bill cassettes  30  of the bill processing device  10 , there is a concern that a mismatch occurs in the balancing process due to a loss of a remaining bill. Furthermore, it is necessary to count the remaining bills as different work from counting the bills inside the bill cassettes  30  of the bill processing device  10 , a workload of a staff increases. 
     On the other hand, by setting a balance-in-hand update timing to a bill ejection time on the withdrawal setting screen, the above-described circumstance can improve. A withdrawal process when a balance-in-hand update timing is a bill ejection time will be described below. 
     (Balance-in-Hand Update Timing: Bill Ejection Time) 
       FIG. 14  is an illustrative diagram showing the withdrawal process when a balance-in-hand update timing is set to a bill ejection time. As shown in  FIG. 14 , when a staff requests a start of a withdrawal from the bill processing device  10  (S 402 ), the control unit  70  instructs the transport unit  24  to eject bills in a designated amount from the bill cassettes  30  (S 404 ). The transport unit  24  starts the ejection of the bills from the bill cassettes  30  based on the instruction (S 407 ), and transports the ejected bills to the cash outlet  18  (S 408 ). Here, the transport unit  24  or the control unit  70  updates the balance-in-hand at the timing at which the bills are ejected from the bill cassettes  30 . In other words, each time one bill is ejected from the bill cassettes  30 , the transport unit  24  or the control unit  70  subtracts one bill from the balance-in-hand of the corresponding denomination. 
     Then, when a jam occurs before all the bills of the designated amount arrive at the cash outlet  18  (S 410 ), a notification of a failure state is output to the control unit  70  in a state in which the bills remain in the transport unit  24  and the cash outlet  18  (S 412 ). 
     Upon receiving the notification of the failure state, the control unit  70  requests checking of whether or not there is a remaining bill to be removed inside the bill processing device  10  from the sensing unit  82  (S 414 ), and the sensing unit  82  responds with presence or absence and the position of the remaining bill to be removed inside the bill processing device  10  (S 416 ). 
     Then, when there is a remaining bill (yes in S 418 ), the display unit  40  displays a withdrawn bill number screen indicating the number of bills ejected from the bill cassettes  30  based on the control of the control unit  70  (S 421  and S 423 ). The withdrawn bill number screen may include withdrawal information  76  indicating the number of withdrawn bills of each denomination as shown in  FIG. 15 . Furthermore, the withdrawn bill number screen may include a message instructing to remove the remaining bill. Alternatively, the withdrawn bill number screen may be displayed after a transition from a removal instruction screen instructing to remove the remaining bill. 
     The staff receives the display of the withdrawn bill number screen, and removes the bill remaining inside the bill processing device  10  (S 432 ). Here, in the present example in which a balance-in-hand update timing is a bill ejection time, a balance-in-hand update process has been performed in the stage of S 432  in which the staff removes the remaining bill, and thus the remaining bill is a bill that the bill processing device  10  recognizes as having been discharged from the device. For this reason, the staff can return the remaining bill to a client, and the staff does not have to return the remaining bill to the bill processing device  10  or to keep the bill separately. Specifically, the staff checks whether or not the number of removed remaining bills matches the number of withdrawn bills shown on the withdrawn bill number screen (S 434 ), and when matching is confirmed, the removed remaining bill can be returned to the client along with bills that have failed to be transported (S 436 ). For example, when withdrawal-requested bills are 50 ten-thousand-yen bills and the removed remaining bills are 45 ten-thousand-yen bills, the staff returns the 45 ten-thousand-yen bills to the client along with 5 ten-thousand-yen bills that have failed to be transported. Note that a bill that fails to be transported can be returned in a withdrawal process after restoration of the bill processing device  10 . In addition, when a removed remaining bill is damaged, a staff may return another bill to a client, instead of the removed remaining bill. 
     As described above, when a balance-in-hand update timing is a bill ejection time, a staff may not keep a remaining bill in a separate place from the bill cassettes  30  of the bill processing device  10 , and thus it is possible to prevent a mismatch from occurring in the balancing process due to a loss of a remaining bill. In addition, when a balance-in-hand update timing is a bill ejection time, there is no remaining bill to be counted as separate work in the balancing process, and therefore it is expected that a workload and a work time necessary for the balancing process are reduced. 
     &lt;6. Fourth Operation&gt; 
     The third operation that can be performed by the bill processing device  10  has been described above. Next, a fourth operation that can be performed by the bill processing device  10  will be described. The fourth operation is an operation relating to a deposit process. In particular, the fourth operation relates to shutter control when a failure occurs in a deposit process. According to the fourth operation, it is possible to quickly return a deposited bill to a customer when a failure occurs in a deposit process as will be descried below in detail. A setting screen for a shutter control in a deposit process will be described, and then the flow of a process according to each round of shutter control will be described below. 
     (Setting Screen for Shutter Control) 
       FIG. 16  is an illustrative diagram showing a specific example of a setting screen for a shutter control in a deposit process. As shown in  FIG. 16 , the setting screen for the shutter control includes a shutter opening selection button  91 , a shutter closing selection button  92 , an OK button  93 , and a cancel button  94 . 
     The shutter opening selection button  91  is a selection button for choosing to open the cash inlet shutter  13  when a failure (a jam) occurs in a deposit process. The shutter closing selection button  92  is a selection button for choosing to maintain the closed cash inlet shutter  13  when a jam occurs in a deposit process. The OK button  93  is a selection button for confirming a setting of the shutter control, and the cancel button  74  is a selection button for maintaining a current setting of the shutter control. 
     By manipulating the setting screen of the shutter control, a staff can set the shutter control when a failure occurs in a deposit process. 
     (When Deposit Failure Occurs: Open Shutter) 
     Next, a process when the shutter control in a deposit process is to “open the shutter” will be described with reference to  FIG. 17 . 
       FIG. 17  is an illustrative diagram showing a process performed when a shutter control in a deposit process is to “open the shutter.” The preceding processes before S 130  and S 139  of  FIG. 17  are the same as from the preceding processes before S 130  and S 139  shown in  FIG. 4 ,  FIG. 6  or  FIG. 9 . 
     As shown in  FIG. 17 , when a jam occurs during a counting process in which deposited bills are being transported from the cash inlet  12  to the temporary reserving unit  22  (S 452 ), a notification of a failure state is output to the control unit  70  in a state in which the bills remain in the transport unit  24  and the cash inlet  12  (S 454 ). 
     Upon receiving the notification of the failure state, the control unit  70  requests checking of whether or not there is a remaining bill to be removed inside the bill processing device  10  from the sensing unit  82  (S 456 ), and then the sensing unit  82  responds with presence or absence and the position of remaining bills to be removed inside the bill processing device  10  (S 458 ). Note that remaining bills to be removed inside the bill processing device  10  include bills remaining in the transport unit  24  and bills remaining in the cash inlet  12 . In addition, it is assumed here that the sensing unit  82  notifies the control unit  70  about the fact that there are bills remaining in the transport unit  24 . 
     Then, when there is a remaining bill in the cash inlet  12  (yes in S 460 ), the display unit  40  displays a remaining bill information screen A based on the control of the control unit  70  (S 462  and S 464 ). The remaining bill information screen A includes a transport unit remaining bill information  95  indicating that the number of bills remaining in the transport unit  24  associated with their respective denominations and a message  96  indicating that there are bills remaining in the cash inlet  12  as shown in  FIG. 18 . 
     Next, the control unit  70  instructs to open the cash inlet shutter  13  (S 466 ), then the cash inlet shutter  13  is opened based on the instruction (S 468 ), and then a notification of a shutter opening completion is output to the control unit  70  (S 470 ). 
     When the staff takes out the bills from the cash inlet  12  (S 472 ) in response to the opening of the cash inlet shutter  13 , a notification of taking out of the bills is output from the sensing unit  82  to the control unit  70  (S 474 ). Upon receiving the notification of the taking out of the bills, or when there is no remaining bill in the cash inlet  12  (no in S 460 ), the control unit  70  causes the display unit  40  to display a remaining bill information screen B (S 476  and S 478 ). The remaining bill information screen B includes a transport unit remaining bill information  95  indicating bills remaining in the transport unit  24  and a message  97  indicating that bills in the cash inlet  12  have been taken out, as shown in  FIG. 19 . 
     Thereafter, the control unit  70  instructs to close the cash inlet shutter  13  (S 480 ), then the cash inlet shutter  13  is closed based on the instruction (S 482 ), and then a notification of a shutter closing completion is output to the control unit  70  (S 484 ). Then, as the staff removes the remaining bills from the transport unit  24  separately, the bill processing device  10  is restored. 
     As described above, in the fourth operation, the cash inlet shutter  13  is automatically opened when a jam occurs during the counting of a deposit. For this reason, bills remaining in the cash inlet  12  can be quickly removed and returned to a client. In addition, through the display of the remaining bill information screen, a staff can ascertain the number of bills remaining in the transport unit associated with their denominations and presence or absence of bills remaining in the cash inlet  12 . Note that, when a shutter control is to “close the shutter” in a deposit process, the cash inlet shutter  13  is maintained to be closed after the occurrence of the jam. In the fourth operation, since any control operation is selected from the plurality of control operations above, it is possible to flexibly respond to changes of specification made in management. 
     &lt;7. Conclusion&gt; 
     Heretofore, preferred embodiments of the present invention have been described in detail with reference to the appended drawings, but the present invention is not limited thereto. It should be understood by those skilled in the art that various changes and alterations may be made without departing from the spirit and scope of the appended claims. 
     Although the example in which the cash inlet  12  is separately provided from the cash outlet  18  has been described above as an example, the bill processing device  10  may have a service window that has a combined function of the cash inlet  12  and the cash outlet  18 . 
     In addition, although the bill processing device  10  is described as a cash processing device and bills as an example of cash to be processed above, the embodiment of the present invention is not limited thereto. For example, the embodiment of the present invention can be applied also to a coin processing device whose cash target to be processed is coins. 
     In addition, the respective steps in the processes of the bill processing device  10  in the present specification are not necessarily processed in chronological order along the orders described in the sequence diagrams. For example, the respective steps in the processes of the bill processing device  10  may be processed in orders different from the orders described in the sequence diagrams or may be processed in parallel. 
     In addition, a computer program for causing a hardware included in the bill processing device  10  to exhibit the functions similar to those of the respective structural elements of the bill processing device  10  described above can also be created. Examples of the hardware includes a CPU, ROM, and RAM. In addition, a memory medium in which the computer program is memorized is also provided.
