Here, the vending machine control unit 3, the numeric keypad 8G, and the operation display unit 22 provided with the numeric keypad 8G function as weighing machine designating means for a customer to designate a weighing machine. On the other hand, if the customer does not press the preset amount key 8B in step SA15, the vending machine
It is determined whether or not the desired preset amount key has been pressed out of 8C (step SA17). If the customer has pressed the preset amount key 8C, the process of step SB16 is performed. If the customer has not pressed the preset amount key 8C, Then, it is determined whether or not the cancel key 8F has been pressed (step SA18). If the customer presses the cancel key F without pressing the preset amount key 8B or the preset amount key 8C, the vending machine control unit 3 returns to the processing of the above-mentioned step SA1, while if the customer does not press the cancel key 8F, the buzzer 10 , A short buzzer sounds (step SA19), and "Please enter again" is displayed on the display unit 9 (step SA20).
The process returns to step 15 to wait for the customer to input the preset amount key 8B. Next, when determining that the customer has deposited coins / banknotes from the coin insertion slot A / banknote insertion slot 5A of the operation display unit 22 (step SA21), the vending machine control unit 3 determines the deposited coins / banknotes (step SA21). Step SA22). The vending machine control unit 3 returns the deposited coin / banknote from the change outlet 23 of the operation display unit 22 when the deposited coin / banknote is false or indistinguishable (step SA2).
3) While the processing of the above-mentioned steps SA19 and SA20 is performed, if the deposited coin / banknote is true, the received coin / banknote is accepted and the deposited amount is counted (step SA24). Thereafter, the vending machine control unit 3 determines whether or not it is necessary to pay out change based on the customer's required preset refueling amount calculated in step SA16 and the customer's deposit amount counted in step SA24. Judgment (step SA2
Five). If the change needs to be paid out, the vending machine control unit 3
After the change is paid out from the change outlet 23 of the operation display section 22 (step SA26), the slip (see FIG. 3) is printed by the printer 7 and issued from the slip issuing port 7A (step SA27), and the next step is performed. Perform the processing of SA28. Thus, the customer receives the slip. On the other hand, the vending machine control unit 3 directly performs the processing of step SA27 when it is unnecessary to pay out change. Further, the vending machine control section 3 stores the print data of the issued slip in the storage section 11 together with the issuance of the slip in step SA27. That is, the storage unit 11 stores the information on the voucher issue NO (corresponding to the voucher identification code in the claims) in the barcode read from the voucher of the customer by the barcode reader 6, and Oil type / unit price / set refueling amount / set refueling amount / deposited amount / change amount /
An area (not shown) for storing used metering machine NO / actual refueling amount / actual refueling amount / intermediate refueling stop flag is secured, and in this area, oil type / unit price / set refueling amount / set refueling amount / deposit amount related to the customer concerned. / Change amount / used meter NO is stored (step SA28). Therefore, the slip also functions as storage means for storing the input amount and the weighing machine to be used in association with each other. Note that the actual refueling amount / actual refueling amount is stored in the above area at the time of refueling termination or during refueling stop, and in the case of refueling stop, a refueling stop flag is set. Then, the vending machine control unit 3 of the automatic refueling vending machine 1 sends the fueling permission and various data (slip issue NO / oil type / quantity / unit price) to the weighing machine control unit 12 of the empty weighing machine selected by the customer in step SA14. / Amount / deposited amount / date / service station name / refueling method) is transmitted (step SA29). Here, the vending machine control unit 3 functions as a refueling permission determination unit that outputs refueling permission to a designated weighing machine. Thereafter, the vending machine control unit 3 returns to the processing of step SA1. On the other hand, if the customer has not pressed the refueling key 8D of the operation display unit 22 in step SA2, the vending machine control unit 3 determines whether or not the customer has pressed the settlement key 8E with the end of refueling (step SA30). When the customer presses the settlement key 8E, "Please set a slip" is displayed on the display unit 9 (step SA31). Thereby, the customer sets the slip received from the slip issuing port 7A of the operation display unit 22 in the slip setting port 6A in the above-mentioned step SA27 (step SA32), and the barcode reader 6 converts the set slip into a barcode (slip issue). NO
/ Oil type / quantity / unit price / amount / deposit amount / date / service station name / refueling method) is read (step SA33). Next, the vending machine control unit 3 checks the bar code of the slip (step SA34). If the bar code is not a valid one, the buzzer 10 sounds a short buzzer sound (step SA35) and the display unit 9 displays Is displayed (step SA36), and the flow returns to step SA32 to wait for the customer to set a slip. On the other hand, if the barcode is valid, the vending machine control unit 3 reads out the slip issuing data stored in the storage unit 11 in step SA28 (step SA37), and stores the barcode in the read slip issuing data in step SA33. It is determined whether there is a slip issuing NO read by the code reader 6 (step SA38). If the issued slip NO is included in the slip issued data read from the storage unit 11, the vending machine control unit 3 displays "Please take out the slip" on the display unit 9 (step SA39).
It is determined whether or not the voucher returned to the voucher set opening 6A has been removed by the customer (step SA40). If the voucher has not been removed, the contents of step SA39 are displayed on the display unit 9 while the voucher is removed. In this case, the change corresponding to the difference between the input amount of the customer and the refueling amount is calculated, and the change is paid back to the change outlet 23 of the operation display unit 22 (step SA41). Here, the vending machine control unit 3 functions as a difference control unit.
Next, the vending machine control unit 3 stores in-process data (for example, 30
If only 20 fuel can be supplied from the vehicle fuel tank when the preset refueling is set,
The slip issuing data corresponding to the actual refueling amount becomes the in-process data) is erased, and a weighing machine NO correspondence table (not shown) indicating the empty / in use state of each weighing machine stored in the storage unit 11 ) Is reset, the weighing machine in-use flag corresponding to the weighing machine NO is reset, and the fact that the weighing machine 2 is empty is stored (step SA42), and then "Thank you" is displayed on the display unit 9. (Step SA43). Thereafter, the vending machine control section 3 causes the printer 7 to print the actual refueling amount / actual refueling amount corresponding to the in-process data, and issues it to the customer through the slip issuing port 7A (step SA44). On the other hand, in step SA38, if the issued slip NO read by the barcode reader 6 is not included in the slip issued data read from the storage unit 11, the buzzer 10 sounds a short buzzer sound (step SA45), and the display is performed. Display "No data available" in Part 9 (Step SA
46), "Please take out the slip" is displayed (step SA47). Next, the vending machine control unit 3 determines whether the voucher has been removed by the customer (step SA48). If the voucher has not been removed, the display unit 9 displays the contents of step SA47, while the voucher is removed. If so, the process returns to step SA1. On the other hand, in step SA30, the customer
If you have not pressed the settlement key 8E of 22, the vending machine control unit 3
Determines whether refueling data has been transmitted via the serial interface IF from the weighing machine used by the customer for refueling (step SA49). If refueling data has not been transmitted, the process returns to step SA1. When the data has been transmitted, the actual refueling amount / actual refueling amount is stored in the storage table of the storage unit 11 in the area corresponding to the slip issuing NO of the customer. Thereafter, it is determined whether or not the customer has stopped refueling the vehicle by the weighing machine halfway (step SA
50). When the customer stops refueling the vehicle by the weighing machine halfway, the vending machine control unit 3 sets a refueling halfway stop flag corresponding to the customer's voucher issue NO in the table of the storage unit 11, and the customer refuels. Is stored (Step SA51), and the process proceeds to Step SA56 described later. On the other hand, if the customer does not stop refueling the vehicle by the weighing machine in step SA50, the vending machine control unit 3 determines whether the preset refueling of the vehicle by the weighing machine is completed (step SA50). SA52). When the vending machine control unit 3 determines that the preset refueling has been completed,
Slip issue NO of the customer in the table of the storage unit 11
Voucher issuance data (oil type / unit price / set refueling amount / set refueling amount / deposited amount / change amount / used metering machine NO / actual refueling amount / actual refueling amount) stored in the area corresponding to
(Step SA53), and resets the in-use flag corresponding to the weighing machine NO in the weighing machine NO correspondence table indicating the empty / in-use state of each weighing machine stored in the storage unit 11, After the fact that the weighing machine has become empty is stored (step SA54), the process returns to step SA1. On the other hand, if it is determined in step SA52 that the preset refueling has not been completed, it is determined whether or not the weighing machine has transmitted from the BUSY information indicating that it is in use (step SA55). If the BUSY information has not been transmitted from the weighing machine, the process returns to step SA1.If the BUSY information has been transmitted, the weighing machine NO in the weighing machine NO correspondence table stored in the storage unit 11 corresponds to the weighing machine NO. Is set, and the fact that the weighing machine is in use is stored (step SA56), and the process returns to step SA1. In the automatic refueling vending machine processing, the customer operates the operation display unit 22.
If you leave the operation for a long time (for example, about 2 minutes),
The automatic refueling vending machine 1 returns to the standby state. ◎ Weighing machine operation processing (FIG. 5) The weighing machine control unit 12 of the weighing machine 2 selected by the customer in the automatic refueling vending machine processing is transmitted from the vending machine control unit 3 of the automatic refueling vending machine 1 via the serial interface IF, When refueling permission and various data (slip issuance NO / oil type / quantity / unit price / amount / deposited amount / year / month / gas station name / refueling method) are received (step SB1), “Preset” is displayed on the operation display section 19. Forehead xx
** Please refuel the circle (or the preset amount xx). ''
Is displayed (step SB2). Next, when the customer who has arrived at the installation location of the selected weighing machine 2 removes the nozzle 17 from the nozzle storage unit (step SB3), the weighing machine control unit 12 outputs a sound “This is XXX ( Is the oil type name set for each weighing machine) ”(Step BS4). The audio output time can be arbitrarily set, for example, to 10 seconds. Further, the weighing machine control unit 12 releases the pump lock of the pump 14 to enable refueling (step SB5), and transmits BUSY information indicating that the weighing machine 2 is in use to the automatic refueling vending machine 1.
Is transmitted to the vending machine control unit 3 (step SB6). Thereafter, the weighing machine control unit 12 determines whether or not the customer who has refueled the vehicle has returned the nozzle 17 to the nozzle storage unit (step SB7). If the customer does not return the nozzle 17 while performing the processing of step SB9 described below, the vehicle fuel tank is determined to be full based on the output of the full tank detection sensor (not shown) arranged in the weighing machine 2. It is determined whether or not it has become (step SB8). When the weighing machine control unit 12 detects that the vehicle fuel tank is full, the buzzer 21 emits a short buzzer sound (step SB9), and the operation display unit 19 displays "Fully filling on the way.
