[Explanation of currency exchange function]
Next, an exchange function that is executed by the microcomputer 13 by the control program stored in the HDD 18 built in the POS terminal 1 will be described.

  FIG. 9 is a flowchart showing the flow of the exchange process. As shown in FIG. 9, when the microcomputer 13 of the POS terminal 1 determines that the exchange key 4f has been pressed (Y in step S1), whether or not there has been a set number by pressing the set number key 4a before the change key 4f is pressed. Is determined (step S2).

  If it is determined that there has been a set number by pressing the set number key 4a before the change key 4f is pressed (Y in step S2), the set number is displayed on the screen of the display 9 as "scheduled amount" (step S3). When the count number of inserted coins from the coin depositing / dispensing device 2 and the bill depositing / dispensing device 3 is received (Y in step S4), the deposit amount is displayed on the screen (step S5).

  FIG. 10 is a front view showing the exchange amount counting dialog displayed on the screen of the display 9. The “scheduled input amount” area of the exchange amount counting dialog is an area for displaying the input (numerical value) amount. If no input (numerical value) is made (Y in step S2), the estimated amount to be inserted is hidden. The “input amount” area of the exchange amount counting dialog displays the total amount of money input to the coin deposit / withdrawal device 2 and the bill deposit / withdrawal device 3. Further, when the count number of money newly inserted into the coin depositing / dispensing device 2 and the bill depositing / dispensing device 3 is received, the total amount inserted in the “input amount” area is updated. The “difference” area of the exchange amount counting dialog displays the difference between the input amount and the planned input amount. If the estimated amount is not displayed, it is not displayed. On the other hand, FIG. 11 is a front view showing a screen display of the customer display 10. As shown in FIG. 11, the customer-side display 10 displays the same total input amount as the “input amount” area of the exchange amount counting dialog displayed on the screen of the display 9.

  The processes in steps S4 to S5 are repeated until it is determined in step S6 that a key operation has been performed.

  If it is determined in step S6 that the confirmation key 4d has been pressed, the process proceeds to step S7, where the “scheduled investment amount” is compared with the actual investment amount. If it is determined in step S6 that the cancel key 4e has been pressed, the coin deposit / withdrawal device 2 and the bill deposit / withdrawal device 3 are notified that the entire amount has been discharged (step S16), Return to S1.

  If the actual investment amount is smaller than the “expected investment amount”, the process proceeds to step S8, where an error message “Insufficient investment amount” is displayed on the display 9 and the customer side display 10, and the C key 4c is pressed. On the condition that it has been pressed (Y in Step S9), the process returns to Step S4, and waits for the reception of the count number of inserted coins from the coin depositing / dispensing device 2 and the bill depositing / dispensing device 3. That is, when the amount of money to be inserted is insufficient, after the C key 4c is pressed, the shortage is inserted into the coin deposit / withdrawal apparatus 2 and the banknote deposit / withdrawal apparatus 3.

  On the other hand, if the actual input amount is the same as the “scheduled input amount” or if there is no input (number) of the “scheduled input amount”, the coin depositing / dispensing device 2 and the bill depositing / dispensing device 3 The “insertion stop” signal for prohibiting the insertion of money is notified (step S10), the “cash register exchange process” is executed with the input amount as the exchange amount (step S11), and the process is terminated. The “cash register exchange process” will be described later.

  Further, if the actual investment amount is larger than the “scheduled investment amount”, the process proceeds to step S12, and for example, “an amount exceeding the planned investment amount has been inserted. Do you want to change? "Is displayed. Then, on condition that the confirmation key 4d is pressed (Y in Step S13), after sending a discharge signal of surplus amount (input amount-input amount) to the coin deposit / withdrawal device 2 and the bill deposit / withdrawal device 3 (Step S14), the process proceeds to Step S10, the coin deposit / withdrawal device 2 and the banknote deposit / withdrawal device 3 are notified of an “insertion stop” signal prohibiting the insertion of money, and the payment process is executed with the input amount as the deposit amount. (Step S11), the process ends. That is, when the confirmation key is pressed when the input amount is large, the surplus amount (input amount−input amount) is discharged and then exchanged.

  If it is determined that the cancel key 4e has been pressed (Y in step S15), the coin deposit / withdrawal device 2 and the banknote deposit / withdrawal device 3 are notified that the entire amount has been discharged (step S16). ), The process returns to step S1. That is, when the stop key 4e is pressed when the inserted amount is large, the inserted amount inserted into the coin depositing / dispensing device 2 and the banknote depositing / dispensing device 3 is completely discharged.

  Next, the “cash register exchange process” in step S11 will be described. Here, FIG. 12 is a flowchart showing the flow of cash register exchange processing. As shown in FIG. 12, in the cash register exchange process, first, the number of payout denominations is calculated (step S21). In the present embodiment, the calculation of the number of payout denominations is performed by comparing the actual input amount with the “payout pattern”. FIG. 13 is an explanatory diagram exemplarily showing a “payout pattern”. For example, when the input amount is 10,000 yen, the “payout pattern” is set such that one sheet of 5,000 yen and five sheets of 1,000 yen.

  If there is a pattern that matches the actual input amount in the “payout pattern” (Y in step S22), the payout pattern is provisionally determined (step S23), and then the coin deposit / withdrawal apparatus 2 is used with the payout pattern. Then, it is determined whether or not there is a denomination exceeding the banknote deposit / withdrawal device 3 (step S24). That is, in step S24, the POS terminal 1 microcomputer 13 acquires the amount of money of each denomination in the coin deposit / withdrawal device 2 and the banknote deposit / withdrawal device 3.

On the other hand, if there is no pattern in the “payout pattern” that matches the actual input amount (N in step S22), pattern generation processing for generating a payout pattern is executed (step S25). In particular,
1. The number of sheets is calculated from the largest payout pattern amount less than the exchange amount.
2. Find the surplus amount with the payout pattern amount.
3. The surplus amount is added in descending order from the denomination and divided until the remainder becomes zero.
Then, it is determined whether or not there is a denomination that exceeds the coin deposit / withdrawal device 2 and banknote deposit / withdrawal device 3 in the payout pattern generated by the pattern generation processing (step S24).

  If it is determined that there is a denomination that exceeds the amount of coin deposit / withdrawal device 2 and bill deposit / withdrawal device 3 (N in step S24), the amount of money exceeds the amount of coin deposit / withdrawal device 2 and bill deposit / withdrawal device 3 After executing the payout number correction process for the seed (step S26), the exchange amount is displayed on the screen of the display 9 (exchange amount counting dialog) for each denomination (step S27). In the payout number correction process, for example, if the denomination whose payout number exceeds the banknote depositing / dispensing device 3 is “1000 yen”, it is distributed to “500 yen”. In the exchange amount counting dialog, it is not possible to specify the number exceeding the amount of money for each denomination, and it is not possible to specify the number for each denomination exceeding the exchange amount.

  On the other hand, if it is determined that there is no denomination exceeding the coin deposit / withdrawal device 2 and banknote deposit / withdrawal device 3 (Y in step S24), the exchange amount is displayed on the screen of the display 9 (exchange amount) for each denomination. It is displayed on the counting dialog) (step S27).

  Through the steps S22 to S27, the function of the denomination number setting means for setting the number of denominations is executed.

  Here, FIG. 14 is a front view showing an example of currency exchange displayed in the currency exchange amount counting dialog. The “maximum number” area of the exchange amount counting dialog shown in FIG. 14 is an area for displaying the number (the amount of money) existing in the coin depositing / dispensing device 2 and the bill depositing / dispensing device 3 of each denomination. The “payout number” area is an area for displaying the number designated for each denomination.

  In the subsequent step S28, the process waits for various key operations in a state in which such an exchange amount counting dialog is displayed.

  When the execution key 4g is pressed in a state in which such an exchange amount counting dialog is displayed, a signal that the exchange amount is paid out for each denomination to the coin deposit / withdrawal device 2 and the bill deposit / withdrawal device 3 (Step S29: payout number instruction means), and the exchange amount is paid out for each denomination.

  When the stop key 4e is pressed, the coin deposit / withdrawal device 2 and the banknote deposit / withdrawal device 3 are notified that the entire amount is to be discharged (step S30), and the entire amount is discharged.

  On the other hand, when the numerical value in the “payout number” area of the exchange amount counting dialog is changed by a key operation (step S31), the process returns to step S27 again, and the changed exchange amount is displayed on the screen of the display 9 for each denomination. Display in (Exchange amount counting dialog). The numerical value in the “paid out number” area may be changed directly by pressing the confirmation key 4d after the numerical value by pressing the numeric key 4a in the “paid out number” area, or provided for each denomination. The number of denominations may be increased / decreased by pressing a “+” button or a “−” button.

  As described above, in the present embodiment, when the exchange process is declared by depressing the exchange key 4f, the number of denominations can be set. When the number of denominations is set, The money depositing / withdrawing apparatus is instructed to pay out the set number of sheets. Thereby, it becomes possible to respond to the exchange breakdown request of those who desire exchange.

  In the present embodiment, the respective housings of the POS terminal 1, the coin depositing / dispensing device 2, and the bill depositing / dispensing device 3 are formed separately, but the present invention is not limited to this. May be integrally formed to operate as a product sales data processing system. In this case, the coin deposit / withdrawal device 2 and the banknote deposit / withdrawal device 3 are the money deposit / withdrawal unit, and the POS terminal 1 is the merchandise sales data processing unit.

  In the present embodiment, the control program is stored in the HDD 18, but the present invention is not limited to this, and the control program is stored in various storage media such as a flexible disk and a CD-ROM (both not shown). May be. Note that the flexible disk and the CD-ROM are not fixedly provided in the POS terminal 1 and have a form as a replaceable storage medium that can be handled as a single unit, and a flexible disk drive and a CD-ROM drive (both not shown).
