The specific operation of the embodiment of the present invention will now be described with reference to FIGS. First, the operation of refueling processing without ejecting the prepaid card during refueling will be described. The prepaid card is inserted into the card reader / writer 21 corresponding to the weighing machine 11, for example. The card reader / writer 21 reads the card identification number, balance data, and the like recorded on the prepaid card, and gives them to the CPU 1 via the transmission circuit 20. CP
As shown in FIG. 3A, U1 writes card identification data, balance data, etc. in the card information reading area 91 of the RAM 9. The CPU 1 checks the validity of the prepaid card, and if it is a defective card, issues an alarm and ejects the prepaid card.

If the prepaid card is normal, RAM
Whether or not the card is an unprocessed card is determined by whether or not the card status specifying the processed card is stored in the area 92 of 9. Since the inserted prepaid card is a card to be processed, it is determined that the card is not an unprocessed card and the weighing machine is selected. That is, the weighing machine 11, for example, is selected from the weighing machine selection key 301 of the keyboard 3. Accordingly, the CPU 1 causes the weighing machine 11
Give a command to the effect that refueling is possible. at the same time,
The CPU 1 stores an unprocessed status in the area 92 of the RAM 9. Then, as shown in FIG. 3B, the unprocessed data is registered in the areas 901 to 904 of the RAM 9.

When refueling is completed, the amount of refueling is measured by the weighing machine 1.
1 to the CPU 1 via the weighing machine control 10. The CPU 1 searches the areas 901 to 904 of the RAM 9 and determines whether or not a status indicating that the prepaid card is held is recorded in the area 904. When it is determined that the prepaid card is held, the transaction amount is subtracted from the balance of the prepaid card according to the amount of refueling, and the new balance is recorded on the prepaid card by the card reader / writer 21. And
Data in areas 901 to 904 are deleted, the prepaid card is ejected, and the printer 6 issues a refueling slip.

Next, the operation of discharging the prepaid card during refueling and refueling will be described. When the prepaid card is inserted, it is determined whether or not the prepaid card is defective, and it is determined that the prepaid card is not an unprocessed card as in the above description. Here, weighing machine selection key 3

Then, refueling processing is performed using another prepaid card.

When refueling is completed, the amount of refueling is given from the weighing machine 11 to the CPU 1. The CPU 1 searches the area of the RAM 9 for unprocessed data and determines whether or not the area 904 stores a status indicating that the prepaid card is not held. When it is determined that the prepaid card is not held, the amount of refueling is stored in the area 903, and the status indicating unprocessed data is stored in the area 904. And
The CPU 1 causes the printer 6 to issue a refueling slip.

When the prepaid card is again inserted into the card reader / writer 21, it is checked whether the prepaid card is normal or not, and if it is normal, it is determined whether or not it is an unprocessed card. If it ’s an unprocessed card,
The unprocessed data in the RAM 9 is searched, and if there is the corresponding unprocessed data, the transaction amount according to the refueling amount is subtracted from the balance recorded in the prepaid card, and the new subtracted balance is recorded in the prepaid card, After deleting the unprocessed data, the prepaid card is discharged and the series of operations is completed.

[0021]

As described above, according to the present invention, in response to the operation of the discharge key during refueling by the refueling machine, data indicating unprocessed data is written in the prepaid refueling ticket to refuel.
