Description

  The present invention relates to a cash register device that operates in conjunction with a depositing / withdrawing machine and performs arithmetic processing related to a trading transaction based on a counting result of the depositing / withdrawing machine.

  In sales transactions of retail stores such as supermarkets and convenience stores, a cash register device called a POS terminal is used. In the cash register device, for each sales transaction, a calculation process related to the sales transaction is performed. Specifically, after the total price of all products that the customer wishes to purchase is derived, the amount of deposits received from the customer is acquired, and the change amount is calculated based on the total price and the amount of deposits. The amount is derived.

  Normally, in such a sales transaction, the store staff handling the cash register device is responsible for counting the deposit and change. On the other hand, in recent years, in order to prevent store staff from miscounting and unauthorized operations, the cash register device is linked to the depositing / dispensing machine, and the depositing / dispensing machine is allowed to count deposits and change. . This depositing / withdrawing machine is an apparatus having a depositing function for counting the amount of money inserted and a dispensing function for discharging a specified amount of money.

  When using a deposit / withdrawal machine, the deposit is put into the deposit / withdrawal machine and the amount is accurately counted by the deposit / withdrawal machine. Then, the accurate counting result is transferred to the cash register device as a signal, and used for the arithmetic processing related to the buying and selling transaction. Further, when the amount of change is derived in the cash register device, the amount of the derived change is transferred to the depositing / dispensing device by a signal, and the amount of money is released from the depositing / dispensing device as change (for example, patent Reference 1).

<1-3. Deposit / withdrawal machine>
FIG. 4 is a diagram showing an external configuration of the depositing / dispensing machine 3. As shown in the figure, the depositing / dispensing machine 3 includes a coin insertion unit 32 for inserting coins into the upper part on the front side, and a bill insertion unit 34 for inserting banknotes on the right side of the front side. In addition, a coin discharge unit 33 for discharging coins is provided on the left side of the front side, and a banknote discharge unit 35 for discharging banknotes is provided on the left side of the banknote insertion unit 34.

  The deposit received from the customer in the settlement process is stored in the depositing / dispensing machine 3 through the coin insertion unit 32 and the bill insertion unit 34. Further, the change is paid out from the depositing / dispensing machine 3 through the coin discharging unit 33 and the banknote discharging unit 35.

  FIG. 5 is a block diagram showing a configuration including the internal configuration of the depositing / dispensing machine 3. As shown in the figure, the depositing / dispensing machine 3 includes therein a coin counting unit 36 that counts coins inserted through a coin insertion unit 32, a coin storage unit 361 that stores coins, and a bill insertion unit 34. The banknote counting part 37 which counts the banknote thrown in via, and the banknote accommodating part 371 which accommodates a banknote are provided. The coin counting unit 36 and the bill counting unit 37 also have a function of determining whether or not the inserted money is a true coin.

  The coin storage unit 361 stores the coins counted by the coin counting unit 36 and supplies the coins to be discharged to the coin discharge unit 33. Similarly, the banknote storage unit 371 stores the banknotes counted by the banknote counting unit 37 and supplies the banknotes to be discharged to the banknote discharge unit 35.

  The depositing / dispensing machine 3 includes a control unit 31 that is a computer that controls the entire apparatus and performs various arithmetic processes. The control unit 31 includes a CPU 301 that performs arithmetic processing, a ROM 302 that stores a control program, a RAM 303 that is a work area for arithmetic processing, and a battery-backed SRAM 304 that is a non-volatile memory that stores various data. ing. Various functions of the control unit 31 are realized by the CPU 301 performing arithmetic processing according to the control program in the ROM 302.

  The above-described coin insertion unit 32, coin release unit 33, bill insertion unit 34, bill release unit 35, coin counting unit 36, and bill counting unit 37 are connected to the control unit 31 via the bus line 30. Thereby, each part of the depositing / dispensing machine 3 operates under the control of the control unit 31, and count results in the coin counting unit 36 and the bill counting unit 37 are input to the control unit 31.

  The control unit 31 of the depositing / dispensing machine 3 includes a coin storage unit 361 and a banknote storage unit based on the counting results of the coin counting unit 36 and the banknote counting unit 37 and the amount of money released by the coin discharging unit 33 and the banknote discharging unit 35. 371 derives and grasps the amount actually stored (hereinafter referred to as “actual balance”). Specifically, an internal variable indicating the actual balance is stored in the RAM 303, and the actual amount is updated by the CPU 301 in accordance with actual money input or release. Furthermore, the control unit 31 also grasps the types and numbers of money stored in the coin storage unit 361 and the banknote storage unit 371.

  The depositing / dispensing machine 3 includes an interface 39 for communicating via the cable 42. The interface 39 is also connected to the control unit 31 via the bus line 30. As a result, the control unit 31 can transmit and receive various signals and data to and from the POS terminal 2.

  In such a depositing / dispensing machine 3, there may be an operation error that the deposit to be inserted cannot be inserted or the change to be released cannot be released. Such operation errors include “change change”, “reject”, and “change change full”.

  “Out of change” is an operation error of the discharge operation in which change to be released cannot be released. When the change is released, a signal for specifying the amount is input from the POS terminal 2 to the depositing / dispensing machine 3. However, if the amount of money stored in the coin storage unit 361 and the bill storage unit 371 is less than the specified amount, or if the combination of the specified amounts cannot be realized with the stored money, no change is released. . In other words, “out of change” occurs.

  “Reject” is an operation error of the input operation in which the deposit to be input cannot be input. When depositing money, even if the money is a true coin, the coin counting unit 36 and the bill counting unit 37 may not recognize the money as a true coin due to dirt or creases. In this case, money that is not recognized as a true coin is released without being stored in the depositing / dispensing machine 3. That is, “reject” occurs.

  “Changing full” is an operation error of the input operation in which the deposit to be input cannot be input. Even when the deposit is inserted, even if the money is recognized as a true coin, if the storage space of the coin storage unit 361 and the bill storage unit 371 is physically full, further money cannot be stored. For this reason, in this case, the money that cannot be stored is discharged without being stored in the depositing / dispensing machine 3. That is, "change full" occurs. In the case of “Reject” and “Changing full”, only a part of the deposited money is stored in the depositing / dispensing machine 3 and the remaining money is released without being stored in the depositing / dispensing machine 3. There can be a scene like this.

  When such an operation error occurs in the depositing / dispensing machine 3, an operation error signal is transmitted from the depositing / dispensing machine 3 to the POS terminal 2 under the control of the control unit 31. The operation error signal includes type information indicating whether the generated operation error is “change change”, “reject”, or “change change full”.

<1-4. Checkout process>
When the POS terminal 2 receives an operation error signal from the deposit / withdrawal machine 3 in the settlement process, the POS terminal 2 performs a process corresponding thereto. Hereinafter, the settlement process of the POS terminal 2 will be described.

  6 and 7 are diagrams illustrating the flow of the settlement process. The series of processes shown in FIG. 6 and FIG. 7 is a process performed for each sales transaction (for each product group that one customer desires to purchase). 6 and 7, the left side shows the processing flow of the POS terminal 2, and the right side shows the processing flow of the depositing / dispensing machine 3.

  First, the barcode attached to the product that the customer desires to purchase is read by the barcode reader 25 of the POS terminal 2. The product master in the POS server 1 is referred to based on the product code thus acquired, and product data such as “product name” and “price” of the product is acquired in the POS terminal 2. The acquired product data is stored in the RAM 202, thereby registering the product for the product. Such product registration is performed for all products that the customer wishes to purchase (step S11).

  When product registration is made for all products, a subtotal key included in the operation key unit 24 is pressed by the sales staff serving as the user. When the subtotal key is pressed (Yes in step S12), the “price” for all the products is totaled by the CPU 201, and the calculated value as a result is stored in the RAM 202 (step S13).

  The derived total price is displayed on the two displays 22 and 23. Based on the display of the total price, payment money as a deposit is transferred from the customer to the store staff. The deposit is put into the coin insertion unit 32 and the bill insertion unit 34 of the deposit / withdrawal machine 3 by the store staff. When the deposit is put into the depositing / dispensing machine 3, the amount of the deposit is counted by the coin counting unit 36 and the bill counting unit 37 of the depositing / dispensing machine 3. Then, a signal indicating the counting result (that is, the amount of deposit) (hereinafter referred to as “counting result signal”) is transmitted from the depositing / dispensing machine 3 to the POS terminal 2 (step S91).

  However, when an operation error of “reject” or “change full” occurs in the depositing / dispensing machine 3, an operation error signal is transmitted from the depositing / dispensing machine 3 to the POS terminal 2. In addition, only part of the deposit money is stored in the depositing / dispensing machine 3 due to an operation error of “reject” or “change change”, and the remaining money is stored without being stored. Both the counting result signal indicating the amount of money and the operation error signal are transmitted from the depositing / dispensing machine 3 to the POS terminal 2.

  The signal transmitted from the depositing / dispensing machine 3 is received by the POS terminal 2 (step S14). If there is no operation error signal in the received signal (that is, no operation error has occurred in the input operation of the depositing / dispensing machine 3) (No in step S15), the deposit is made based on the count result signal. Is acquired by the CPU 201 and stored in the RAM 202 (step S16).

  On the other hand, if there is an operation error signal in the received signal (that is, if an operation error has occurred in the input operation of the depositing / dispensing machine 3) (Yes in step S15), it is first sold that there was an operation error. It is displayed on the side display 22 (step S17).

  Next, when the counting result signal is received together with the operation error signal, the amount of money that can be put into the depositing / dispensing machine 3 out of the deposit (hereinafter referred to as “the amount that has been put in”) based on the counting result signal. Is acquired by the CPU 201 and stored in the RAM 202 (step S18).

  Next, the money of the deposit that could not be inserted into the depositing / dispensing machine 3 (hereinafter referred to as “uninjected amount”) is input by the store staff via the operation key unit 24. Thereby, the uninjected amount is acquired by the POS terminal 2 and stored in the RAM 202. Money that could not be put into the depositing / dispensing machine 3 is stored in the drawer 27 or the like. The uninjected amount can be said to be an error amount that could not be inserted into the depositing / dispensing machine 3 due to an operation error of “reject” or “change change” (step S19).

  Next, the invested amount and the uninjected amount are added by the CPU 201, and the result is used as the deposit amount. The derived deposit amount is stored in the RAM 202 (step S20).

  When the deposit amount is obtained in this way, the CPU 201 subtracts the total price from the deposit amount, and the result is used as the change amount. The derived change amount is displayed on the two displays 22 and 23 (step S21 in FIG. 7). Next, a change instruction signal designating the change amount and instructing the release of the change is transmitted from the POS terminal 2 to the depositing / dispensing machine 3 (step S22).

  In response to the receipt of the change instruction signal, the depositing / dispensing machine 3 releases the change amount specified by the change instruction signal from the coin discharge unit 33 and the bill release unit 35. The released money is delivered to the customer by the store staff as change. When the deposit / withdrawal machine 3 normally releases change in this way, a normal completion signal is transmitted from the deposit / withdrawal machine 3 to the POS terminal 2. However, when an operation error “out of change” occurs in the dispensing operation of the depositing / dispensing machine 3, an operation error signal is transmitted from the depositing / dispensing machine 3 to the POS terminal 2 (step S92).

  The signal transmitted from the depositing / dispensing machine 3 is received by the POS terminal 2 (step S23). If the received signal is a normal completion signal (that is, if an operation error has not occurred in the discharging operation of depositing / dispensing machine 3) (No in step S24), the process proceeds directly to step S27.

  On the other hand, when the received signal is an operation error signal (that is, when an operation error occurs in the discharging operation of the depositing / dispensing machine 3) (Yes in step S24), first, the sales side display indicates that there is an operation error. 22 (step S25). If there is such an error display, the change is not released from the depositing / dispensing machine 3, so the change is taken out from the drawer 27 or the store office and delivered to the customer.

  Subsequently, the amount of money that could not be released by the depositing / dispensing machine 3 (hereinafter referred to as “unreleased amount”) is acquired. The deposit / withdrawal machine 3 according to the present embodiment does not release all the money to be changed in the case of “out of change”. For this reason, the change amount derived in step S <b> 21 is acquired by the CPU 201 as an unreleased amount as it is and stored in the RAM 202. It can be said that the unreleased amount is an error amount that could not be released from the depositing / dispensing machine 3 due to an operation error of “out of change” (step S26).

  In step S27, the theoretical balance stored in the RAM 203 is updated based on the total price derived in step S13. Specifically, the total price is added by the CPU 201 to the theoretical balance at that time, and the result is set as a new theoretical balance (step S27). However, when an operation error occurs in the depositing / dispensing machine 3 in the above process, the theoretical balance and the actual balance are different at this point (a specific example will be described later).

  Next, the contents of the sales transaction are printed on a recording sheet by the print issuing unit 26 and issued as a receipt (step S28). Normally, the settlement process is completed by issuing this receipt. However, if an operation error signal has been received from the deposit / withdrawal machine 3 in the above process, an error handling process is further performed to cope with the operation error (steps S29 and S30).

  FIG. 8 is a diagram showing details of the flow of error handling processing. First, the time measured by the timer 205 is acquired (step S31). The time acquired at this time is hereinafter treated as an operation error occurrence time. Note that when the operation error signal is received, the time measured by the timer 205 may be acquired, and that time may be set as the operation error occurrence time.

  Next, the CPU 201 identifies type information of an operation error that has occurred in the depositing / dispensing machine 3. As described above, the operation error signal received from the deposit / withdrawal machine 3 includes type information indicating whether the generated operation error is “change change”, “reject”, or “change change”. Therefore, the type information of the generated operation error is easily specified based on the operation error signal (step S32).

  Next, information related to the operation error acquired as described above is stored in the SRAM 204. The SRAM 204 stores an error table, which is table data in which information regarding all generated operation errors is registered. In the error table, an operation error occurrence time, operation error type information, and an error amount resulting from the operation error are recorded in association with each other (step S33).

  FIG. 9 is a diagram illustrating an example of the error table 72. As shown in the figure, in the error table 72, information related to one operation error is registered in one record R. That is, in each record R, the occurrence time, type information, and error amount related to one operation error are associated. The record R in the error table 72 is registered every time an operation error of the deposit / withdrawal machine 3 occurs in the settlement process. Therefore, by referring to the error table 72, it is possible to grasp afterwards what kind of operation error has occurred in the depositing / dispensing machine 3.

  When the information is recorded in the error table 72, the same information as the information recorded in the error table 72 is printed on the recording sheet by the print issuing unit 26 and issued as an error slip (step S34). FIG. 10 is a diagram illustrating an example of the issued error slip 71. As shown in the figure, in the error slip 71, an occurrence time 71a, type information 71b, and error amount 71c relating to one operation error are printed. Each time an operation error occurs, such an error slip 71 is issued. For this reason, by managing the error slip 71 without using an apparatus for viewing the error table 72, it is possible to grasp afterwards when and what kind of operation error has occurred in the depositing / dispensing machine 3. It becomes possible.

  Note that multiple operation errors may occur, such as “reject” and “change change” in one settlement process. In this case, the error handling process shown in FIG. 8 is executed for each operation error that has occurred. Therefore, for each operation error that occurs, the record R of the error table 72 is registered and an error slip 71 is issued.

<1-5. Bank registration processing>
In the POS terminal 2, after the above settlement process is repeated, a process called a cash order registration process is executed after the business hours of the store are over. In the cash balance registration process, the theoretical balance managed by the POS terminal 2 is compared with the actual balance, which is the actual storage amount of the deposit / withdrawal machine 3, and the existence of excess or deficiency is confirmed.

  FIG. 11 is a diagram illustrating a flow of the cash amount registration process. Hereinafter, the flow of the cash amount registration process will be described with reference to FIG.

  First, the theoretical balance stored in the RAM 203 is acquired (step S41). Next, a predetermined control signal is transmitted to the depositing / dispensing machine 3, and the actual balance managed by the control unit 31 of the depositing / dispensing machine 3 is acquired from the depositing / dispensing machine 3 to the POS terminal 2 (step S42).

  Subsequently, the theoretical balance is subtracted from the actual balance by the CPU 201, and the result is set as an excess / deficiency amount. The excess / deficiency is a positive value when the actual balance is larger than the theoretical balance (when the balance is excessive), and a negative value when the actual balance is less than the theoretical balance (when the balance is insufficient) (step S43). .

  Next, the error table 72 stored in the SRAM 204 is referred to, and information (occurrence time, type information, error amount) related to all operation errors that have occurred in the settlement process within business hours is acquired (step S44).

  The actual balance, theoretical balance, excess / deficiency, and information on all operation errors obtained as described above are printed on the recording paper by the print issuing unit 26 and issued as a single cash register. (Step S45).

  FIG. 12 is a diagram showing an example of the cash register 73 issued in this way. As shown in the figure, the cash register 73 includes a cash balance column 73a indicating information relating to a balance and an operation error column 73b indicating information relating to an operation error.

  In the cash balance column 73a, an actual balance, a theoretical balance, and an excess / deficiency amount are shown. By browsing the cash balance column 73a, it is possible to grasp the situation of excess or deficiency occurring in the settlement process within business hours, along with the actual balance and the theoretical balance.

  On the other hand, in the operation error column 73b, operation error type information, the number of occurrences of the operation error, and the total error amount resulting from the operation error are recorded for each type of operation error. Therefore, by browsing the operation error column 73b, it is possible to easily grasp what operation errors have occurred and how much error amount has occurred in the settlement process during business hours. . Therefore, even if an excess or deficiency (difference between the actual balance and the theoretical balance) occurs, it is possible to easily identify what causes the excess or deficiency.

<1-6. Specific example of change>
Next, a specific example when “out of change” occurs in the checkout process will be described.

  FIG. 13 is a diagram showing the specific operations of the POS terminal 2 and the deposit / withdrawal machine 3 and the transition of the theoretical balance and the actual balance in chronological order in an example checkout process in which “out of change” has occurred. . Reference numerals T11 to T19 in the figure indicate time points. For convenience of explanation, it is assumed that the theoretical balance and the actual balance at the settlement processing start time T11 coincide with each other and are “0 yen”.

  First, at time T12, the total price is derived at the POS terminal 2 as “900 yen”.

  Next, at time T <b> 13, a thousand yen bill of deposit is put into the deposit / withdrawal machine 3. As a result, the amount of the deposit is counted as “1,000 yen”, and a counting result signal sg 1 indicating the counting result is transmitted from the depositing / dispensing machine 3 to the POS terminal 2. Further, the count result “1,000 yen” is added to the actual balance “0 yen”, and the actual balance is updated to “1,000 yen”.

  Next, at time T14, the count result signal sg1 is received by the POS terminal 2. As a result, the deposit amount is acquired by the POS terminal 2 as “1,000 yen”.

  Next, at time T15, the total price “900 yen” is subtracted from the deposit amount “1,000 yen”, and the change amount is derived as “100 yen”. Then, a change instruction signal sg 2 designating the change amount “100 yen” is transmitted from the POS terminal 2 to the depositing / dispensing machine 3.

  Next, at time T16, the change instruction signal sg2 is received by the depositing / dispensing machine 3. The depositing / dispensing machine 3 should discharge the change according to the change instruction signal sg2. However, since only a thousand-yen bill is accommodated therein, it is not possible to discharge “100 yen”. For this reason, “change change” occurs, and an operation error signal sg 3 indicating that is transmitted from the depositing / dispensing machine 3 to the POS terminal 2.

  Next, the operation error signal sg3 is received by the POS terminal 2 at time T17. Thereby, in the POS terminal 2, the change amount “100 yen” is acquired as the unreleased amount (error amount).

  Next, at time T18, the total price “900 yen” is added to the theoretical balance “0 yen”, and the theoretical balance is updated to “900 yen”. As a result, the theoretical balance becomes “900 yen”, the actual balance becomes “1,000 yen”, and “+100 yen” becomes excessive or insufficient (balance excess).

  Next, at time T <b> 19, an error handling process is performed, and a record R indicating information regarding the “change change” that has occurred is registered in the error table 72. At the same time, an error slip 71 shown in FIG. 10 is issued. In this error slip 71, “Changing out” is recorded as the type information of the operation error, and “100 yen” is recorded as the error amount.

  When the cash amount registration process is executed in a state where only the payment process shown in FIG. 13 is performed, the cash balance registration slip 73 shown in FIG. 14 is issued. As shown in FIG. 14, the cash balance column 73a of the cash register 73 indicates that an excess balance of “100 yen” has occurred. On the other hand, the operation error column 73b indicates that one “change change” has occurred and the error amount resulting from the “change change” is “100 yen”. Therefore, by visually recognizing the banknote registration slip 73, it is possible to easily grasp that the excess or deficiency has occurred due to “running out of change”. In addition, by referring to the error slip 71 shown in FIG.

<1-7. Specific examples of rejection>
Next, a specific example when “reject” occurs in the checkout process will be described.

  FIG. 15 is a diagram showing the specific operations of the POS terminal 2 and the depositing / dispensing machine 3 and the transition of the theoretical balance and the actual balance in chronological order in the checkout process as an example in which “reject” has occurred. Symbols T21 to T28 in the figure indicate time points. For convenience of explanation, it is assumed that the theoretical balance and the actual balance at the settlement processing start time T21 coincide with each other and are “100 yen”. More specifically, it is assumed that one coin is stored in the depositing / dispensing machine 3 at the start time T21.

  First, at time T22, the total price is derived as “900 yen” at the POS terminal 2.

  Next, at time T23, an attempt is made to insert the thousand-yen bill of deposit into the depositing / dispensing machine 3. However, a "reject" occurs, and the deposit is dispensed without being inserted into the depositing / dispensing machine 3. For this reason, an operation error signal sg4 indicating that “reject” has occurred is transmitted from the depositing / dispensing machine 3 to the POS terminal 2.

  Next, at time T24, the operation error signal sg4 is received by the POS terminal 2. Then, an uninjected amount (error amount) is acquired as “1,000 yen” in the POS terminal 2 by the operation input of the store staff. Since the invested amount does not exist, the deposit amount is acquired by the POS terminal 2 as “1,000 yen”.

  Next, at time T25, the total price “900 yen” is subtracted from the deposit amount “1,000 yen”, and the change amount is derived as “100 yen”. Then, a change instruction signal sg 2 designating the change amount “100 yen” is transmitted from the POS terminal 2 to the depositing / dispensing machine 3.

  Next, at time T26, the change instruction signal sg2 is received by the depositing / dispensing machine 3. In accordance with the change instruction signal sg2, the one hundred yen coin stored in the deposit / withdrawal machine 3 is discharged from the deposit / withdrawal machine 3 as change. Further, the release amount “100 yen” is subtracted from the actual balance “100 yen”, and the actual balance is updated to “0 yen”.

  Next, at time T27, the total price “900 yen” is added to the theoretical balance “100 yen”, and the theoretical balance is updated to “1,000 yen”. As a result, the theoretical balance is “1,000 yen”, the actual balance is “0 yen”, and an excess or deficiency (insufficient balance) of “−1,000 yen” occurs.

  Next, at time T <b> 28, an error handling process is performed, and a record R indicating information regarding the generated “reject” is registered in the error table 72. At the same time, an error slip 71 shown in FIG. 16 is issued. In this error slip 71, “Reject” is recorded as the type information of the operation error, and “1,000 yen” is recorded as the error amount.

  When the cash amount registration process is executed in a state where only the checkout process shown in FIG. 15 is performed, a cash balance registration slip 73 shown in FIG. 17 is issued. As shown in FIG. 17, the cash balance column 73a of the cash register 73 indicates that a balance shortage of “1,000 yen” has occurred. On the other hand, the operation error column 73b indicates that one “reject” has occurred and the error amount resulting from the “reject” is “1,000 yen”. Therefore, by visually recognizing the cash amount registration slip 73, it can be easily understood that the excess or deficiency is caused by “reject”. In addition, by referring to the error slip 71 shown in FIG. 16 as well, it is possible to confirm the time of occurrence of “reject”.

<1-8. Specific example of change change>
Next, a specific example in the case where “change change full” occurs in the settlement process will be described.

  FIG. 18 is a diagram showing the specific operations of the POS terminal 2 and the deposit / withdrawal machine 3 and the transition of the theoretical balance and the actual balance in chronological order in an example checkout process in which “change full” has occurred. . Symbols T31 to T39 in the figure indicate time points. For convenience of explanation, it is assumed that the theoretical balance and the actual balance at the settlement processing start time T31 coincide with each other and are “100 yen”. More specifically, it is assumed that one coin is stored in the depositing / dispensing machine 3 at the start time T31.

  First, at time T32, the total price is derived as “900 yen” at the POS terminal 2.

  Next, at time T33, an attempt is made to insert two 500-yen coins into the depositing / dispensing machine 3. Although one 500-yen coin has been successfully inserted into the depositing / dispensing machine 3, ”Occurs, and the other 500-yen coin cannot be thrown in and released. As a result, the counting result becomes “500 yen”, and the counting result signal sg1 indicating the counting result is transmitted from the depositing / dispensing machine 3 to the POS terminal 2. Further, the counting result “500 yen” is added to the actual balance “100 yen”, and the actual balance is updated to “600 yen”. Further, an operation error signal sg5 indicating that “change is full” is also transmitted from the depositing / dispensing machine 3 to the POS terminal 2.

  Next, at time T34, both the count result signal sg1 and the operation error signal sg5 are received by the POS terminal 2. As a result, the POS terminal 2 acquires the charged amount as “500 yen”.

  Next, at time T <b> 35, an uninjected amount (error amount) of “500 yen” is acquired in the POS terminal 2 by an operation input by the store staff. Then, the invested amount “500 yen” and the uninjected amount “500 yen” are added, and the deposit amount is acquired as “1,000 yen” in the POS terminal 2.

  Next, at time T36, the total price “900 yen” is subtracted from the deposit amount “1,000 yen”, and the change amount is derived as “100 yen”. Then, a change instruction signal sg 2 designating the change amount “100 yen” is transmitted from the POS terminal 2 to the depositing / dispensing machine 3.

  Next, at time T37, the change instruction signal sg2 is received by the depositing / dispensing machine 3. In accordance with the change instruction signal sg2, the one hundred yen coin stored in the deposit / withdrawal machine 3 is discharged from the deposit / withdrawal machine 3 as change. Also, the release amount “100 yen” is subtracted from the actual balance “600 yen”, and the actual balance is updated to “500 yen”.

  Next, at time T38, the total price “900 yen” is added to the theoretical balance “100 yen”, and the theoretical balance is updated to “1,000 yen”. As a result, the theoretical balance becomes “1,000 yen”, the actual balance becomes “500 yen”, and an excess or deficiency (insufficient balance) of “−500 yen” occurs.

  Next, at time T <b> 39, an error handling process is performed, and a record R indicating information on the generated “change full” is registered in the error table 72. At the same time, an error slip 71 shown in FIG. 19 is issued. In the error slip 71, “change full” is recorded as the type information of the operation error, and “500 yen” is recorded as the error amount.

  When the cash amount registration process is executed in a state where only the payment process shown in FIG. 18 is performed, the cash balance registration slip 73 shown in FIG. 20 is issued. As shown in FIG. 20, the cash balance column 73a of the cash register 73 indicates that a balance shortage of “500 yen” has occurred. On the other hand, the operation error column 73b indicates that one “change change” has occurred and the error amount resulting from the “change change” is “500 yen”. Therefore, by visually recognizing the banknote registration slip 73, it can be easily understood that the excess or deficiency has occurred due to the “change full”. Further, by referring to the error slip 71 shown in FIG. 19 as well, it is possible to confirm the occurrence time of “change full”.

<1-9. Summary>
As described above, in the POS terminal 2, the amount stored in the deposit / withdrawal machine 3 is derived as the theoretical balance based on the total price that is the calculated value in the settlement process. On the other hand, when an operation error of any of the money input operation and the discharge operation occurs in the depositing / dispensing machine 3, the type information of the operation error is specified based on the operation error signal. Further, an error amount that is an amount that could not be inserted or discharged due to the operation error is also acquired. As described above, when an operation error of the depositing / dispensing machine 3 occurs, the type information of the operation error and the error amount resulting from the operation error are acquired, so that the actual balance and the theoretical balance are different due to the operation error. Even if a shortage occurs, it can be handled appropriately.

  In the cash register process, information on the actual balance, the theoretical balance, the excess and deficiency, and all the operation errors that have occurred are acquired and printed on a single recording sheet as a cash register 73. Is done. Therefore, even when excess or deficiency occurs, it is possible to easily grasp the specific situation of excess or deficiency and what causes the excess or deficiency.

  Each time an operation error occurs, information on the operation error (occurrence time, type information, and error amount) is stored in the SRAM 204 and printed on a recording sheet and issued as an error slip 71. Therefore, information for each operation error can be easily grasped later.

<2. Second Embodiment>
Next, a second embodiment will be described. In the first embodiment, even if an operation error of the deposit / withdrawal machine 3 occurs, the theoretical balance is not corrected. However, in the present embodiment, when an operation error occurs, the theoretical balance is calculated based on the error amount. The balance is adjusted.

  The contents of the settlement process of this embodiment are almost the same as those of the first embodiment shown in FIGS. 6 and 7, but the contents of the error handling process (step S30 in FIG. 7) are different. .

  FIG. 21 is a diagram showing details of the flow of error handling processing according to the present embodiment. The processing from step S51 to step S54 is the same as the processing from step S31 to step S34 shown in FIG. That is, the operation error occurrence time is acquired based on the time counted by the timer 205 (step S51), and the type information of the operation error generated based on the operation error signal is specified (step S52). Subsequently, information related to the acquired operation error is recorded in the error table 72 (step S53), and the information is printed on a recording sheet and an error slip 71 is issued (step S54).

  Next, the type information of the generated operation error is confirmed (step S55), and the theoretical balance stored in the RAM 203 is corrected by the CPU 201 based on the type information of the operation error and the error amount due to the operation error. The

  When the generated operation error is “out of change”, that is, the operation error of the release operation, the theoretical balance is less than the actual balance by the amount of error that could not be released. Therefore, the error amount is added to the theoretical balance at that time, and the result is set as a new theoretical balance (step S56).

  On the other hand, when the generated operation error is “reject” or “change full”, that is, the operation error of the input operation, the theoretical balance is larger than the actual balance by the error amount that could not be input. Therefore, the error amount is subtracted from the theoretical balance at that time, and the result is set as a new theoretical balance (step S57).

  Thus, in this embodiment, even if an operation error occurs, the theoretical balance is corrected based on the type information of the operation error and the error amount. For this reason, the actual balance and the theoretical balance can be matched, and the occurrence of excess or deficiency due to an operation error can be prevented.

  Such correction of the theoretical balance can be performed if information indicating whether the generated operation error is an input operation or a discharge operation and an error amount can be obtained. For this reason, the operation error type information is not information indicating “change change”, “reject”, and “change change full”, but is at least one of the operation error of the input operation and the operation error of the discharge operation. Any information can be used.

<3. Other embodiments>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible. Hereinafter, such other embodiments will be described. Of course, you may combine the form demonstrated below suitably.

  In the above embodiment, the type information of the operation error is specified based on the operation error signal. However, when the store staff as the user operates and inputs the type information of the operation error via the operation key unit 24 or the like, the operation error Error type information may be specified. In such a case, the operation error signal may not be transmitted from the depositing / dispensing machine 3 to the POS terminal 2.

  Further, the type information of the operation error may be specified based on the process in the settlement process at the time when the operation error occurs. For example, if an operation error occurs in the process of depositing deposits (step S14 in FIG. 6), it can be identified as an operation error of the deposit operation, and the operation error in the process of releasing change (step S23 in FIG. 7). If this occurs, it can be identified as an operation error of the discharge operation.

  In the second embodiment, the theoretical balance is corrected in the error handling process. However, when the theoretical balance is updated (step S27 in FIG. 7), the theoretical balance is corrected in consideration of the error amount. It may be.

  In addition, the deposit / withdrawal machine 3 can perform a deposit process for inserting money (cash reserves, etc.) and a withdrawal process for releasing money (sales proceeds, etc.) regardless of the sales transaction. When performing this deposit process and withdrawal process, a signal is transmitted to the POS terminal 2 and the theoretical balance is also updated. The theoretical balance may be corrected in consideration of the error amount at the time of updating the theoretical balance accompanying the deposit processing and withdrawal processing.
