Description

TECHNICAL FIELD The present invention relates to an oil supply device for selectively displaying various information.

(Prior Art) With the widespread use of microcomputers, it has become possible to easily perform various types of information processing, and the refueling device is not limited to simply displaying the amount of refueling, but can selectively display unit prices, fees, and campaign messages. It has become possible to display.

Conventionally, such a display content is selected by a selection switch provided on the main body of the fueling apparatus, so that it is displayed even to a credit customer who does not need to display the charge due to an operator's operation error. There was an inconvenience that it did.

(Object) The present invention has been made in view of such a problem, and an object thereof is to select display contents in association with the type of card used before refueling operation,
Therefore, it is an object of the present invention to provide a refueling device that can always perform accurate display.

(Example) Then, the Example which illustrated the detail of this invention is demonstrated below.

FIG. 3 shows an embodiment of an oil supply device to which the present invention is applied. In the drawing, reference numeral 1 is an oil supply device connected to a POS 4 of an office 3 via a signal line 2, and a housing 5 Dot matrix type display panel 6 and card reader 7 on the outer surface of
A key board 8 and a nozzle hook 10 associated with the nozzle switch 9 are provided, and a nozzle hose 11 is provided inside.
Via a pump motor 13, a pump 14, and a flow meter 15 for pumping the liquid to the oil supply nozzle 12 via a flow meter, a flow rate pulse signal from a flow rate pulse transmitter 16 attached to the flow meter 15, and a nozzle switch 9 A control device 17 for controlling the motor 13 and the display panel 6 in response to signals and signals from the key board 8 and the card reader 7 is provided.
In the display area of the dot matrix type display panel 6, the units "YEN / LITER" 6a, "LITER" 6b, "YEN" 6c related to the displayed numerical values are shown as shown in FIG. The unit "LITER" 6b of the amount of refueling, which is particularly important information, is composed of white and is easily conspicuous.

FIG. 1 shows an embodiment of the above-mentioned control device 17, and reference numeral 20 in the drawing denotes a transmitting / receiving means for transmitting / receiving data to / from the POS 4 via the signal line 2, and a card reader via this. While the data from 7 and the refueling data are sent to the POS 4, the unit price data and the refueling permission signal from the POS 4 side are received. 21 is a refueling work permission means,
The refueling operation permission signal is output under the condition that both the ON of the nozzle switch 9 and the refueling permission signal are input. Reference numeral 22 denotes an arithmetic unit, which receives the signal from the unit price storing unit 23 which receives the unit price data from the POS 4 and the signal from the counting unit 24 which integrates the flow rate pulse while returning to zero by the refueling work permission signal and corresponds to the amount of refueling. The calculated charge is calculated. Reference numeral 25 is a display switching means for inputting data from the advertisement text storage means 26 storing the contents of the campaign message, the counting means 24, the calculation means 22, and the unit price storage means 23, while the signal from the clock means 27 is input. Is input as a switching signal. The clocking means 27, which has received the signal obtained by inverting the refueling work permission signal from the refueling work permission means 21 by the inverter 31, stops the switching signal and counts the counting means 2.
4, the data of the calculation means 22 and the unit price storage means 23 are output to the display panel drive means 28, and the inverter switch 31 when the nozzle switch 9 is turned off and the refueling work permission signal from the refueling work permission means 21 disappears. From the time when the time T set in the clocking means 27 operated by the signal elapses until the refueling work permission signal is output again, the data in the advertisement text storage means 26 is displayed via the display panel drive means 28 and the dot matrix type display panel. It is configured to output to 6. Reference numeral 29 is a data transfer permission means, and the counting means 44, the calculation means 22, and the unit price storage means 2 because the nozzle switch 9 is turned off after the refueling operation is completed.
The data from 3 is output to the transmitting / receiving means 20.

On the other hand, the POS 4 comprises a transmission / reception means 41, a control means 42, a printer 43, and storage means 44, 45, 46 for storing unit price data, sales data, and refueling data, and based on a signal from the card reader 7. If it is a proper card, it will output a refueling work permission and determine whether the card is for cash sale or credit sale,
In the former case, unit price data is output, in the latter case, zero is output, and the refueling liquid data sent after the end of refueling is processed as required. Incidentally, reference numeral 30 in the drawing
Shows a motor driving means for driving the pump motor 13 by outputting a refueling work permission signal.

Next, the operation of the apparatus thus configured will be described based on the flow chart shown in FIG.

In the standby state, since the refueling work permission signal is not output from the refueling work permission means 21, the display switching means 25
Selects data from the advertisement text storage means 26 and displays it on the dot matrix type display panel 6 (step S1).

In such a state, a card for cash sale is put on the card reader 7 to refuel the customer of the cash transaction (step S2), and the data from now on is transmitted / received by the transmitting / receiving means 2
It is transferred to the POS 4 via 0 (step S3). Upon receipt of the data (step S4), the POS 4 checks the validity of the card and, if the card is valid, determines the type of the card. Since this is a cash sale card, the unit price is read from the unit price data storage means 44. It is transmitted (step S5). When receiving the data (step S6), the unit price is
The refueling work permission means 2 is updated and set in the unit price storage means 23.
A refueling permission signal is input to 1 (step S7).

When the nozzle 12 is removed from the nozzle hook 10 to refuel, the nozzle switch 9 is turned on (step S
8), the refueling work permission means 21 outputs a signal to cause the counting means 24 and the computing means 22 to return to zero, and the display switching means 25 is operated to display the content displayed on the dot matrix type display panel 6 from the campaign sentence, unit price, refueling. The amount and amount of all refueling data are switched (step S9), and the motor 13 is operated to drive the pump 14 (step S10).

When refueling is started in such a state, the flow rate pulse is integrated by the counting means 24 and converted into a flow rate, and is also multiplied by the unit price storage means 23 by the arithmetic circuit 22 and converted into a charge (steps S11 and S12). ). The flow rate, charge, and unit price are output to the dot matrix type display panel 6 via the display switching circuit 25, and the unit “YEN / LITER” 6a, “LITE” of the display panel 6 is output.
It is displayed at a position corresponding to "R" 6b and "YEN" 6c. As a result, the meanings of the numbers displayed on the display panel 6 become clear at a glance, among which the "LITER" 6b
Since the unit of is remarkably formed, the refueling amount will not be mistaken.

When the nozzle 12 is returned to the nozzle hook 10 after a predetermined amount of fuel has been supplied, the nozzle switch 9 is turned off (step S
13). The refueling operation permission means 21 stops the pump 14 by stopping the output of the refueling operation permission signal in response to the OFF of the nozzle switch 6, and at the same time operates the time counting means 27 and the data transfer permission means 29. As a result, the amount of fuel and the charges stored in the counting means 24 and the computing means 22 are output to the POS 4 via the transmitting / receiving means 20 (step S1).
4), the POS 4 receiving this data (step S1
5) The refueling data is processed and the printer 43 prints it on the slip (step S16).

In this way, when the time T set in the clock means 27, for example, 30 seconds has elapsed and a signal is about to be output (step S17), the display switching means 25 causes the advertisement text storage / display means 2 to operate.
The data of No. 6 is selected and the display content of the dot matrix type display panel 6 is switched from the refueling data to the campaign sentence (step S18). For customers who receive points for discounted sales by members, etc., if they receive their membership card and hang it on the card reader 7, POS4
Reads out the unit price corresponding to this from the unit price data storage means 44, and the refueling device executes the same operation as described above.

When a credit sales customer arrives, the credit sales card is placed on the card reader 7, and the data from this is transferred to the POS 4 via the transmission / reception means 20. In step S5, the POS 4 determines that the card type is a credit sales card, reads "zero" as unit data from the unit price data storage means 44, and transmits it. In this case, no unit price is set in the unit price storage means 23 in step S7. When the nozzle 12 is removed to execute refueling (step S20), the refueling work permission means 2
1, the counting means 24 and the computing means 22 are reset to zero, and the display content of the dot matrix type display panel 6 is switched from the campaign sentence to the display of refueling data for only the refueling amount (step S21), and the pump motor 13 is driven ( Step S
22). When refueling is started in such a state, only the amount of refueling is displayed on the dot matrix type display panel 6.

When the nozzle 12 is returned after the refueling of a predetermined amount is completed, the data transfer permission means 29 is activated to transfer the refueling amount data of the counting means 24 to the POS 4, and is stored as the sale data in the storing means 46 at the same time. A slip is prepared by the printer 43. When the time T set in the timekeeping means 27 has elapsed, the display panel 6 displays the campaign text in the advertisement text storage means 26 instead of the refueling amount.

In addition, in this embodiment, the size of each character is the same, but when only the amount of refueling is displayed as in credit sales, the shape of the character is enlarged and the amount of refueling is spread over the entire display panel surface. It can also be displayed.

Further, in this embodiment, the unit price data is received from the POS 4 based on the data read by the card reader, but it goes without saying that the same effect can be obtained even if the unit price data storage means is provided in the main body of the fueling apparatus. Nor.

(Effect) As described above, in the present invention, the nozzle is hooked,
Nozzle switch for detecting disconnection, oil supply means driven by the signal of this nozzle switch, flow rate detection means for detecting the flow rate of liquid discharged from the nozzle, counting means for calculating an integrated flow rate based on the signal of the flow rate detection means, transaction Card reading means for reading a card indicating a condition, unit price storing means for storing unit price data output from the POS based on the data of the card reading means, counting means for counting signals from the nozzle switch by inputting a refueling permission signal from the POS To perform a reset, and a refueling operation permitting means for driving the refueling means, a means for calculating a charge from the integrated flow rate and unit price data, a display means, and an integrated flow rate and a charge selectively as necessary. Since the display switching means for outputting is provided, it is possible to select the content of the data to be displayed during refueling. The setting operation of the switch operation and trading conditions it is possible to prevent the erroneous selection of display information for the simplification and customer refueling work can be a waste.
