When the purchased product is confirmed, the billing amount is displayed on the LCD 210, and the purchaser inserts cash into the deposit / withdrawal apparatus 221.

  In the additional amount notification device 400, the charged amount calculation device 410 acquires the charged amount (A) from the POS terminal unit 300 (step ST11). And the acceptance amount (B) received with the banknote processing apparatus 221a and the coin processing apparatus 221b with the acceptance amount calculation apparatus 420 is acquired (step ST12). Then, the change amount calculation unit 430 calculates the change amount (C) (step ST13). This calculation is obtained by calculating change amount (C) = acceptance amount (B) −billing amount (A). Thereby, the amount of change is calculated.

  Next, when there is change (Yes in step ST14), the additional amount calculation device 450 determines whether the last digit of the change is “0” (step ST15), and the last digit is “0”. The amount of change is calculated as follows. (Step ST16). The additional amount is obtained by calculating the additional amount (D) = the charged amount (A) + the change amount (C) −the received amount (B).

  If there is no change (No in step ST14), or if the last digit of change is “0”, the process of the additional amount notification device 400 is terminated, and the settlement terminal 201 is notified accordingly. The process ends.

  Next, the calculation of the additional amount calculation device 450 will be described. In this example, this calculation is performed by executing a program based on the calculation formula. In this case, the value of the additional amount and the change amount can be changed according to the change state actually prepared in the deposit / withdrawal device 221.

  An example of the calculation result is shown in FIG. In this table, a change amount (C) and an additional amount (D) are described for a pair of a charge amount (A) and a receipt amount (B). The additional amount calculation device 450 outputs the additional amount (D) and the change amount (C) not including 1 yen and 5 yen corresponding to the input charged amount (A) and the received amount (B).

  For example, a case where the purchase amount is 1772 yen will be described.

  When the amount received is 1780 yen, the change is 8 yen. In this case, three 1-yen coins and 1 5-yen coin are returned as change. In order not to include the 1 yen coin and the 5 yen coin in the change, it is only necessary to add 2 yen as an additional amount. In this case, the change is 10 yen and the 1 yen coin and the 5 yen coin are not included.

  Further, when the amount received is 1800 yen, the change is 28 yen. In this case, in order to prevent 1 yen coin or 5 yen coin from being included by setting the last digit of change to “0”, it is only necessary to insert 2 yen or 22 yen as an additional amount. It will be 50 yen.

  Furthermore, when the amount received is 2000 yen, the change is 228 yen. In this case, in order to change the last digit of change to “0” so that the change does not include 1 yen coin or 5 yen coin, add 2 yen, 22 yen, 72 yen, 272 yen as an additional amount. Will be 230, 250, 300 and 500 yen.

  When the received amount is 10000 yen, the last digit of change is set to “0” so that the change does not include 1 yen coin or 5 yen coin, as in the case where the received amount is 2000 yen.

  Such amount determination processing may be performed using the program as described above, but can be performed by referring to a table storing calculation results obtained in advance.

  And the alerting | reporting apparatus 460 displays the guidance image about the additional amount (D) obtained by this calculation on LCD210 (step ST17).

  7 to 9 are schematic views showing display images at the time of change processing in the self-checkout terminal. FIG. 7 shows a display image when 1800 yen is paid for the charged amount of 1772 yen. That is, on the LCD 210, as the display image 500, in addition to the guide image 510 about the charge amount, the additional amount, and the change amount, the guide image 520 about the additional amount so that the change does not include 1 yen coin and 5 yen coin. Is displayed. The guide image 520 indicates that 2 yen should be added to change the change to 30 yen, and 22 yen should be added to change the change to 50 yen.

  Here, when there is no additional input for a predetermined time (No in step ST18) or when an instruction button (not shown) is pressed, the processing in the additional amount notification device 400 ends, and the deposit / withdrawal device 221 operates normally. Returning to the processing, predetermined change processing is performed, and 28 yen is paid as change from the change payment device 440.

  On the other hand, when the purchaser inserts an additional amount as indicated by the guidance image 520 (Yes in step ST18), the processing in steps ST12 to ST18 is performed again, and the display image in the next stage is displayed on the LCD 210. .

  FIG. 8 shows a case where 2 yen is added as an additional amount. In the display image 600, the guidance image 610 about the billing amount, the additional amount, and the change amount indicates that the change is 30 yen and the 1-yen coin and the 5-yen coin are not included. Further, in this example, a guide image 620 is displayed on the display image 600, and it is indicated that 20 yen should be added in order to further change the change to 50 yen.

  When additional charging is performed in this state, the processing of step ST12 to step ST18 is performed again. On the other hand, when there is no additional input for a predetermined time (No in step ST18) or when an instruction button (not shown) is pressed, the processing in the additional amount notification device 400 ends and the deposit / withdrawal device 221 changes 30 yen. As pay.

  FIG. 9 shows a display image 700 when 2,000 yen is paid for the charged amount of 1772 yen. In this case, the guide image 710 for the charged amount, the additional amount, and the change amount indicates that the change is 228 yen. In the guide image 720, 2 yen is used to change the change to 230 yen. This indicates that 22 yen should be added to change the change to 250 yen, and 222 yen should be added to change the change to 500 yen.

  As described above, according to the additional amount notification device according to this example, the additional amount display device calculates the additional amount with “0” as the last digit of the amount of change calculated from the inserted amount, Since this additional amount is displayed to the purchaser, the purchaser does not have to accept a coin of a small denomination as a change by additionally inserting the displayed amount. Therefore, it is possible to avoid troublesomeness caused by the purchaser receiving coins of a small denomination, and to reduce the frequency of replenishment of small coins for change.

  In the above example, the additional amount is notified by displaying characters on the LCD 210. However, the notification is not limited to characters, and signs and figures may be displayed. The notification may be made by voice. In the above example, the additional amount calculation device 450 calculates the amount of the additional amount so that one digit from the least significant digit of the change amount becomes “0”, but two or more digits from the least significant amount become “0”. The additional amount can be calculated as follows.
