FIG. 1 is a flow chart for explaining the operation of an embodiment of the present invention, FIG. 2 is a flow chart showing the operation when refueling, and FIG. 3 is a flow chart for carrying out post-processing. It is a flowchart which shows operation. First, the operation for refueling will be described. The operator inserts the advance card handed by the customer into the card reader / writer 8. Next, the operator selects the weighing machine selection key 71 on the keyboard 7.
To select the weighing machine to refuel. Then, the refueling processing device records the unprocessed flag indicating that the inserted card requires post-processing and the weighing machine number indicating the selected weighing machine, and ejects the card. Here, the card of another customer can be read. The operator can read a plurality of cards continuously by the same card reader / writer 8 by repeating the above operation.

Next, the post-processing operation will be described. The operator presses the post-processing key 73 shown in FIG. 5 to insert the card into the card reader / writer 8. Then, the refueling processing device determines, for example, the refueling amount and the refuelable amount (remaining oil amount) after refueling
Record and print on the inserted card and eject the card.

By the operation shown in FIG. 3, the updated refuelable amount is recorded on the card, so that when it becomes necessary to refuel, the card can be used for refueling.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS.

First, the refueling operation will be described. The clerk inserts the advance sale card given by the customer into the card reader / writer 8.
In step S1 (abbreviated as S1 in the figure), C
When PU1 determines that a card has been inserted,
Go to step S4. The card reader / writer 8 reads the number data for identifying the card and the data indicating the amount of oil that can be refueled from the inserted card. The data read by the card reader / writer 8 is given to the CPU 1 via the transmission circuit 5.

The CPU 1 stores the given data in the card information storage area 31 of the RAM 3 and checks the validity of the card based on the data in step S4. Subsequently, in step S5, when the CPU 1 determines that the card is an invalid card, the process proceeds to step S11, the card is ejected and the operation ends, but when it is determined that the card is a valid card, the process proceeds to step S6. move on. Here, the card is determined to be invalid not only when the card is a stolen card, when the refuelable amount is "0", etc., but also when the unprocessed flag is set on the card.

In step S6, the clerk operates the weighing machine selection key 71 to select the weighing machine 6 for refueling, for example, weighing machine # 1. In response, the CPU 1 in step S7 commands the weighing machine # 1 that refueling is possible. Next, in step S8, the CPU 1 codes the unprocessed flag indicating that post-processing is necessary and the number of the weighing machine for refueling, and writes it in the card inserted in the card reader / writer 8, and then, In step S9, the inserted card is ejected.

Subsequently, in step S10, the CPU 1 stores the data stored in the card information storage area 31 in the unprocessed data storage area 32 for each weighing machine number. For example, when the weighing machine # 1 is used, the data is stored in the area 321. Then, it returns to step S1 and the card of another customer can be inserted.

When the card of another customer is inserted into the card reader / writer 8, the CPU 1 executes the above steps S1 and S4.
Step S10 is executed. However, in step S6, the clerk selects an empty weighing machine 6 each time.

In this way, when a plurality of cards are continuously read, the above-mentioned steps S1 and S4 are performed.
Since the loop of step S10 proceeds in a short time, it is possible to refuel a plurality of customers almost at the same time.

When refueling is completed, each weighing machine 6 gives data indicating the amount of refueling to the CPU 1 via the weighing machine controller 4. In response, when CPU 1 determines in step S2 that refueling is completed, the process proceeds to step S12.
Subsequently, the CPU 1 identifies the weighing machine 6 that has transmitted the refueling amount data, reads the refuelable amount data from the area corresponding to the weighing machine number in the unprocessed data storage area 32,
A new refuelable amount is calculated by subtracting the refueling amount from the refuelable amount. Subsequently, the CPU 1 stores the calculated new refuelable amount in the unprocessed data storage area 32. Subsequently, in step S13, the CPU 1 issues a refueling slip and ends the operation.

Next, the post-treatment of the card used for refueling will be described.

The card used for refueling records the refuelable amount before refueling, so it is necessary to update the data after refueling. Therefore, the clerk first presses the post-processing key 73, and then inserts the customer's card for which refueling is completed into the card reader / writer 8 again. Accordingly, when the CPU 1 determines in step S3 that the post-processing key 73 has been pressed, in step S14 the card reader / writer 8
The data read by is stored in the card information storage area 31. Succeedingly, in a step S18, the CPU 1 determines whether or not the inserted card is an unprocessed card depending on whether or not the unprocessed flag is set. If the CPU 1 determines in step S16 that the card is not an unprocessed card, the process proceeds to step S19 to eject the card and ends the operation. If it is determined that the card is an unprocessed card, the process proceeds to step S17.

In step S17, the CPU 1 reads the applicable new refuelable amount data from the unprocessed data storage area 32 based on the data for identifying the card among the data stored in the card information storage area 31, and in step S18 it reads it. The new refuelable amount data is written in the card inserted in the card reader / writer 8, and then the card is ejected in step S19 to end the operation.

In the above embodiment, when the post-processing key 73 is pressed,
Although the post-processing is performed, it may be determined whether to perform the post-processing based on the data read from the card, and the refueling process or the post-processing may be performed based on the determination.

As described above, according to the present invention, after the reading means reads the data from the card, it is possible to refuel with the weighing machine,
Since the data indicating that at least post-processing is required is written on the card by the writing means and the other card can be read by the reading means, the weighing machine for refueling can be used without idle time. The customer can reduce the waiting time for refueling.
