Description

[Detailed description of the invention] The present invention relates to the oil supply amount H.

At gasoline filling stations, the selling price of oil is often set at 14 between customers who purchase large quantities of oil (usually fixed credit customers) and customers who pay in cash (usually so-called walk-in cash customers). , customers who are forced to purchase at a higher price than the selling price to other customers feel uncomfortable.

Cash customers often specify the desired amount of refueling in terms of amount (for example, 5,000 yen), so it is convenient to use a refueling machine with a refueling amount display for cash customers. When the amount of refueling is displayed in monetary terms, it is required by law to also display the unit price of refueling, so the unit price of refueling for each customer becomes clear.

By the way, the use of credit cards has become widespread in recent years, and most of the credit customers now use credit cards.

The present invention provides a refueling device with an amount display in which a credit card can be used, so that when refueling is performed using a credit card, the refueling amount and unit price are not displayed, thereby causing discomfort due to differences in refueling unit prices. is not given to customers.

The illustrated embodiment will be described in detail below.

) and a printer 13b that creates a slip based on the refueling information.

14 is a nozzle case, 15 is a nozzle detection switch, and the operation of removing the nozzle/I/7 from the nozzle case 14t.
In response, the switch 15 is activated. For example, when the nozzle/L 77 is removed from the nozzle case 714, the nozzle signal from the switch 15 becomes /-i (high) level (H), and the nozzle/L
/7 to nozzle case 141 return and low level /l
/ (L) becomes.

FIG. 2 shows an example of a circuit configuration. The unit price setting circuit 11 selectively generates the standard unit price signal 0 and the specific unit price signal C'. The standard unit price is set in advance, and the specific unit price is automatically set, for example, by a card reader reading the unit price rank recorded in advance on the card.

First, we will explain how to refuel without using a card. When the nozzle) v7 is removed from the nozzle case 14, the pulse counter 16 and calculation circuit 17 are reset by the nozzle signal L→H, and the motor drive circuit 1B
The pump motor 4 is energized via the pump motor 4, and the recording section 13 is made ready for operation.

The nozzle signal H is further applied to a unit price setting circuit 11 and a cutoff circuit 19.

When only the nozzle V signal H is input, the unit price setting circuit 11 generates the standard unit price signal C, and the AND condition of the input of the nozzle signal H and the input of the card reading signal from the card reader 12 is established. Then, a specific unit price signal C' is generated. Therefore, in this case, since it is assumed that the card is not being used, the unit price setting circuit 11 generates the standard unit price signal C. The standard unit price signal C is applied to the display drive circuit 210, the arithmetic circuit 17, and the recording section 131.

2o is a power supply circuit, which is a drive circuit 21 for the oil supply amount indicator 10a.
a directly, and the drive circuit 2 of the refueling amount display 10b.
1b and the drive circuit 21c of the refueling unit price display 10c, operating power is indirectly supplied to each of them via the cutoff circuit 19. The cutoff circuit 19 operates to cut off when an AND condition is established between the input of the nozzle signal H and the input of the card reading signal S, and cuts off the supply of operating power to the amount display drive circuit 21b and the unit price display drive circuit 21c. In this case, it is assumed that the card reading signal is not generated because the card is not used, so the cutoff circuit 19 allows the supply of operating power to the display drive circuits 21b and 21c.

Therefore, the display drive circuit 21a receives the standard unit price signal C from the unit price setting circuit 11 and displays the standard unit price (
For example, 170 yen/l) is displayed.

When the nozzle /L/7 is operated to supply oil, the pulse generator 8 generates a flow rate pulse a corresponding to the amount of oil measured by the flowmeter 5I. The counting circuit 16 counts these pulses,
The count value (oil supply amount) is given to the drive circuit 21a and the recording section 13. The drive circuit 21a displays the amount of oil supplied on the oil amount display 10a.
are displayed sequentially.

The flow rate pulse a is also given to the arithmetic circuit 17, and the arithmetic circuit 1
7 performs a calculation using the unit price signal O and the flow rate pulse a, and provides the calculation result (refueling amount) to the drive circuit 21b and the recording section 13, and the drive circuit 21b causes the refueling amount display 10b to sequentially display the refueling amount.

When the refueling is completed and the nozzle/L/7 is returned to the nozzle case 14, the motor drive circuit 18 deenergizes the motor 4 according to the nozzle signal H→L, and in the recording section 13, the recording machine 13a outputs the signal from the unit price setting circuit 11. The standard unit price, the count value from the counting circuit 16 (the amount of oil supplied), and the calculated value from the calculation circuit 17 (the amount of oil supplied) are recorded, and the printer 13b prints out these data.

If the card is used before or after removing the nozzle from the nozzle case 14, the card reader 1
2 supplies read card information (customer number, etc.) to the recording section 131 as a signal d, and 1 also supplies a card reading signal S to the unit price setting circuit 11 and the cutoff circuit 19f. Therefore, as mentioned above, when the nozzle/1/7 is removed from the nozzle case 14, the AND condition of the nozzle signal H generated and the card reading signal is satisfied, and therefore,
The unit price setting circuit 11 generates a specific unit price (for example, 165 yen/l) signal 0', but the cutoff circuit 19 generates the fuel amount display 1.
Since the drive circuit 21b of 0b and the drive circuit 21C of the unit price display 10o are cut off from the m source circuit 20, the specific unit price and the refueling amount based on this specific unit price as fueling progresses are not displayed on the display 10b%10c.

Since the display drive circuit 21a is never cut off from the power supply circuit 20, the amount of refueling as the refueling progresses is indicated by the refueling amount display 1.
Displayed on 0a.

Since the specific unit price signal C/ from the unit price setting circuit 11 and the calculation result (refueling amount) from the calculation circuit 17 are given to the recording unit 13 together with the count value (fueling ff1) from the counting circuit 16, these Recording of refueling information and creation of slips are performed in the same way as when no card is used.

That is, when the nozzle /L/7 is returned to the nozzle case 14, the recording unit 13a records the customer number and the above refueling information in the recording section 13 according to the nozzle signal H-+L, and the printer 13
After printing out this information, the bonder motor 4 is deenergized, the card reader 12 is reset, and the signal disappears. However, the cutoff circuit 19 then
is removed from the nozzle case 14 and the shut-off state is maintained until the nozzle signal becomes L-+H, and the shut-off state is canceled only when the signal is cleared when the nozzle signal becomes L-)H.

Otherwise, the arithmetic circuit 17 will then determine that the nozzle signal is L-+.
Since it is not reset until H is reached, the refueling amount is displayed when the nozzle is returned to the nozzle case, which is inconvenient.

Note that when the nozzle signal changes from L to H, if the card reader is already reading the next card, the signal is output again, so this signal is cut off due to the AND condition with the nozzle signal H. The circuit 19 will not be released from the cut-off state and will be maintained.

When the nozzle is returned to the nozzle case and the nozzle signal changes from H to L and the card reading signal disappears, the unit price setting circuit 11 maintains the output of the specific unit price signal 0/.

In this case as well, as mentioned above, the specific unit price is not displayed because the cutoff circuit 19 maintains the cutoff state until the next nozzle is removed from the nozzle case and the nozzle signal changes from L to H. If there is no card reading signal when the signal becomes L-+H, the standard unit price will be displayed. If the card reader has already read the next card and outputs a signal, the unit price setting circuit 11 outputs a specific unit price signal Ol corresponding to that card.

In addition to the above-mentioned ground-mounted refueling system, the present invention can also be implemented as a high-mounted or lowered refueling system.

In this case, when the refueling nozzle at the lower end of the hose suspended from a high place is at the refueling standby position 1.8 m above the ground, the nozzle signal is L, and when the refueling nozzle is lowered from this standby position to the refueling possible position. The nozzle signal is configured so that the nozzle signal becomes I, -+H.

As described above, according to the present invention, when a card is used, the refueling unit price and refueling amount are not automatically displayed, thereby avoiding the inconvenience caused by different sales prices being displayed depending on the customer. be able to.
