When the customer sees the display on the display section 9 and presses a corresponding one of the oil type keys 8A, the vending machine control section 3 performs the process of step SA9, which will be described later. That is, in the processes of Step SA4 and Step SA5, it is determined whether the customer has pressed the oil type key 8A for the desired oil type (for example, regular gasoline/unleaded high octane gasoline/leaded high octane gasoline/diesel oil/kerosene, etc.). On the other hand, if the customer presses the cancel key 8F without pressing the oil type key 8A (step 5A6), the vending machine control unit 3 returns the display on the display unit 9 to the initial display of step SAI, while If the cancel key 8F is not pressed, the buzzer 10 makes a short buzzer sound (step 5A7), displays "Please enter again" on the display 9 (step 5A8), and then proceeds to the process of step SA4 above. return. Next, when the customer presses the desired oil type key 8A in step SA4 or step SA5, the vending machine control unit 3
refers to the weighing machine No. correspondence table stored in the storage unit 11 that indicates the empty state/in-use state of each weighing machine, and determines whether there is an empty measuring machine for the oil type that corresponds to the oil type specified by the customer. Determination is made (step 5A9). If there is no empty weighing machine, the vending machine control section 3 causes the buzzer 10 to emit a short buzzer sound (step 5AIO), and displays "Please wait for a while while the weighing machine is in use" on the display section 9 (step 5A11). ), the display on the display section 9 is returned to the initial display at step SA1. On the other hand, if there is an empty weighing machine, the vending machine control unit 3 displays the empty weighing machine NOJ on the display unit 9 (steer knob 5A12) and selects the refueling method (preset refueling/full refueling, etc.). "Please" is displayed (Step 5A13). Next, when the customer inputs the empty measuring machine N○ used for refueling from the numeric keypad 8G (step 5A14), the vending machine control unit 3 determines whether the customer has pressed a desired preset amount key among the preset amount keys 8B. If the customer presses the preset amount key 8B, the amount required for refueling the preset amount is calculated (step 5A15).
Step 5A16). On the other hand, if the customer has not pressed the preset amount key 8B in step 5A15, the vending machine control unit 3 determines whether or not the customer has pressed a desired preset amount key among the preset amount keys 8C. If the user has pressed the preset amount key 80, the process of step 5B16 is performed, while if the preset amount key 8C has not been pressed, it is determined whether or not the cancel key 8F has been pressed (step S A 18). The customer presses the Brise/Nodo amount key 8B and the preset amount key 8C.
If the customer presses the cancel key 8F without pressing the cancel key 8F, the vending machine control unit 3 returns to the process of step SAI described above, while if the customer does not press the cancel key 8F, the buzzer 10 sounds a short buzzer sound (step 5A19). ), “

Next, when the vending machine control unit 3 determines that the customer has deposited coins/banknotes from the coin insertion slot 4A/bill insertion slot 5A of the operation display unit 22 (Step 5A21), the vending machine control unit 3 determines the deposited coins/banknotes. (Step 5A22). If the deposited coins/banknotes are fake or unidentifiable, the vending machine control section 3 returns the deposited coins/banknotes from the change number 1) 1 slot 23 on the operation display section 22 (step 5A23), and then returns the deposited coins/banknotes to the above-mentioned ste/knob 5A19.
, Step 5A20 is performed, and if the deposited coin/banknote is true, the deposited coin/banknote is accepted and the deposited amount is incremented by z1 (Step 5A24). Thereafter, the vending machine control unit 3 determines whether or not it is necessary to dispense change based on the customer's required preset refueling amount calculated in step 5A16 and the deposited amount of the customer counted in step 5A24. Determination is made (step 5A25). If it is necessary to dispense change, the vending machine control section 3 dispenses the change from the change outlet 23 of the operation display section 22 (step 5A26), and then prints out a slip (see FIG. 3) using the printer 7 to issue the slip. While issuing from lower A (step 5A27), the next step 5A28
Process. The customer receives the slip. On the other hand, if the vending machine control unit 3 does not need to pay out change, it directly performs the process of step 5A27. In addition, the vending machine control section 3 issues the slip in steps SA and 27, and also stores the print data of the issued slip in the storage section.
Store to 1. That is, the storage unit 11 stores information about the customer's vehicle in association with the slip issue number (corresponding to the slip identification code in the claims) in the barcode read from the customer's slip by the barcode reader 6. Type of oil to be refueled / 'Unit price / Set oil supply amount / Set oil supply amount / Deposit amount / Change amount / Measuring machine used / Actual oil supply I / Actual oil supply amount / Area for storing mid-refueling stop flag (not shown) is secured, and the oil type/unit price/set oil supply amount/set oil supply amount/deposit amount/change amount/used weighing machine No. for the customer are stored in the area (Step 5A28). Note that the actual refueling amount/actual refueling amount is stored in the area when refueling is completed or when refueling is stopped midway through refueling, and when refueling is stopped midway through refueling, the mid refueling stop flag is set. will be played. Then, the vending machine control unit 3 of the automatic refueling vending machine 1 sends the refueling permission and various data (slip issue number,
/Oil type/Oil type/Quantity/Unit price/Amount/Class/Date/Refueling station name/Refueling method) is sent (Step 5A29). Thereafter, the vending machine control section 3 returns to the process of step SA1. On the other hand, if the customer has not pressed the refueling key 8D on the operation display section 22 in step SA2, the vending machine control section 3 determines whether the customer has pressed the payment key 8E upon completion of refueling (Step 5A30). If the customer presses the payment key 8E, the message "Please set the slip" is displayed on the display section 9 (step 5A31). As a result, when the customer sets the slip received from the slip issuing lower A of the operation display section 22 on the Stellar 7'5A27 into the slip setting opening 6A (step 5A32), the barcode leak 6 detects the barcode ( Slip issue No.○/oil type/quantity/unit price/
Amount/Deposit Amount/Date/Refueling Station Name/Refueling Law) is read (Step 5A33). Next, the vending machine control unit 3 checks the barcode on the slip (step 5A34), and if the barcode is not a legitimate one, causes the buzzer 10 to emit a short buzzer sound (step 5A35), and displays the display unit 9. After displaying the message "Please set the slip" (step 5A36), the process returns to step 5A32 and waits for the customer to set the slip. On the other hand, if the barcode is genuine,
The vending machine control unit 3 reads the slip issuing data stored in the storage unit 11 in step 5A28 above.Step S A 3
7) The above step 5A3 is included in the read slip issuance data.

A short buzzer sound is sounded (step 5A45), and the display section 9 displays "No applicable data" (step 5A46) and "Please remove the slip" (step 5A47). Next, the vending machine control section 3 determines whether the slip has been removed by the customer (step 5A48), and if the slip has not been removed, the display section 9 displays the contents of step 7'5A47, while
If the slip has been removed, the process returns to step SAI. On the other hand, in step 5A30, if the customer has not pressed the payment key 8E on the operation display section 22, the vending machine control section 3 determines whether refueling data has been transmitted via the serial interface IF from the weighing machine that the customer used to refuel. If the refueling data has not been sent, the process returns to step S A l above, while
When refueling data is transmitted, the actual refueling amount/actual refueling amount is stored in the corresponding area of the table of the storage unit 11 corresponding to the customer's slip issue number. After this,
It is determined whether the customer has stopped refueling the vehicle using the weighing machine (step S A 50). When the customer stops refueling the vehicle using the weighing machine midway, the vending machine control unit 3 sets the mid-refueling stop flag corresponding to the customer's slip issue number in the table of the storage unit 11)
After memorizing that the customer has stopped refueling midway (step 5A51), the process moves to step 5A56, which will be described later. On the other hand, in step 5A50, if the customer has not stopped the refueling of the vehicle by the weighing machine, the vending machine control unit 3 determines whether or not the preset refueling of the vehicle by the weighing machine has been completed (step 5A52). When the vending machine control unit 3 determines that the preset refueling has been completed, the vending machine control unit 3 stores the customer's slip issuance data (oil type/unit price/ Set refueling amount / Set refueling amount / Deposit amount / Change amount / Measuring machine used / Actual refueling amount /
(actual refueling amount) (step 5A53),
The in-use flag corresponding to the weighing machine No. in the weighing machine No. correspondence table indicating the vacant state/in-use state of each weighing machine stored in the storage unit 11 is reset, and the weighing machine becomes vacant. After memorizing the information (step 5A54)
), the process returns to step SAI above. On the other hand, in the above step 5A52, Brisse. If it is determined that refueling has not been completed, it is determined whether BUSY information indicating that the weighing machine is in use has been transmitted from the weighing machine (step S A 55). If the BUSY information has not been sent from the weighing machine, the process returns to step SAI, but if the BUSY information has been sent,
After setting the weighing machine control unit flag corresponding to the weighing machine number in the weighing machine number correspondence table stored in the storage unit 11 and storing that the weighing machine is in use (step 5A56), the above Return to step SAI processing. In addition, in the above-mentioned automatic fuel vending machine processing, the customer operates the operation display section 22.

By setting and operating the fill-up key, it is possible to refuel in an amount corresponding to the amount that the customer has inserted into the automatic refueling vending machine 1.When refueling is complete, the amount of refueling at the time of completion of refueling can be equivalent to the amount of money that the customer has inserted. If the amount is insufficient, the excess amount can be refunded to the customer in the same way as in the above embodiment.

【Effect of the invention】

As explained above, according to the present invention, the following effects can be achieved. ■For example, even if a customer stops refueling their own vehicle due to reasons such as the vehicle's fuel tank becoming full during self-service preset refueling from a weighing machine,
It becomes possible to reliably refund to the customer the difference obtained by subtracting the amount corresponding to the actual amount of refueling up to the time of stopping refueling from the amount deposited by the customer before starting preset refueling. ■Furthermore, since the slip issued from the outside equipment can be used as a receipt for the customer, it is suitable for the management of self-service gas stations. ■Also, if the compatible oil type of the customer's vehicle and the oil type of the measuring machine used for refueling are different, providing a means to notify the wrong type of oil makes it possible to prevent incorrect refueling. ■Also, since it is possible to avoid installing a special reading means for reading slips for each weighing machine, there is no need to increase costs (it is possible to realize the gas station system of the present invention). .
