FIG. 1 shows an embodiment of the control device 20 described above. In the figure, reference numeral 1 is a counting means for counting the flow rate pulses from the flow rate pulse transmitter 22, and is a nozzle switch 27.
After zeroing by turning on, the flow pulse counting is started,
The count value is output to the first charge calculating means 2, the second charge calculating means 12, and the display switching means 3 which will be described later. Reference numeral 2 denotes the above-mentioned first charge calculating means, which calculates the selling charge based on the data from the first unit price storage means 4 storing the standard unit price per unit volume and the data from the counting means 1. Reference numeral 3 denotes a display switching means, which receives data from the counting means 1, the first charge calculation means 2, the first unit price storage means 4, and the message storage means 5, and the nozzle switch 2
7 is turned on and the redisplay button 36 is turned on, the liquid supply amount, the standard unit price, and the charge based on this, that is, the standard charge, and from the message display timer 6 activated by turning off the nozzle switch 27 or turning on the redisplay button 36. Is used to display the contents of the message storage means 5 on the main display 23 via the main display driver 7. Reference numeral 10 denotes a discount charge display circuit which is a characteristic part of the present invention, and includes a card reader 32 and a unit price setting button 34.
A second unit price storage means 11 for storing a discount unit price set separately from the standard unit price, a second rate calculation means 12 for calculating the product of the data from the second unit price storage means 12 and the counting means 1, and an integration. Signal from button 35 and nozzle switch 27
The switch means 14 for outputting the data of the second charge calculating means 11 and the sub-display driver 15 for outputting the discount unit price and the discount charge to the sub-display 31. It consists of Reference numeral 16 in the drawing denotes a motor control means for driving and stopping the pump drive motor 25 by turning on and off the nozzle switch 27.

In this embodiment, the nozzle switch 27 is in the standby state.
Is OFF, the data of the message storage means 5, for example, "Welcome. It is unleaded gasoline." Is displayed on the main display 23 through the switching means 3.
In such a state, when a customer who should be sold at a normal price comes and removes the nozzle 26 from the nozzle hook to start the liquid supply, the nozzle switch 27 is turned on to zero the counting means 1 and switch the display. The unit 3 is switched to display the standard unit price and zero flow rate of the first unit price storage unit 4 on the main display 23.
The pump driving motor 25 is driven at the same time.
When the nozzle valve is opened in such a state, the flow rate pulse is input from the flow rate pulse transmitter 22 to the counting means 1 and integrated. This integrated value, that is, the liquid supply amount is input to the first charge calculation means 2, multiplied by the standard unit price of the first unit price storage means 4, and converted into a charge. The data of the liquid supply amount, the standard unit price, and the standard selling price are input to the main display 23 via the display switching means 3, and are displayed in large amounts as the liquid supply amount, the standard unit price, and the standard selling price.

When the nozzle 26 is returned to the nozzle hook at the stage when the liquid supply is completed in this way, the nozzle switch 27 is turned off and the motor 25 is stopped, and at the same time, the timer 6 starts operating and the main display 23 is displayed after a predetermined time. The displayed liquid supply amount, standard unit price, and standard selling price are erased, and the data in the message storage means 5 is displayed instead. In addition, when it is desired to view the previous sales data after displaying the message, the previous liquid supply redisplay button 36 of the panel 30 is pressed to display the counting means 1, the first charge calculating means 2, and the first unit price storing means 4. The stored data is output to the main display 23 via the display switching means 3, and the liquid supply amount, the standard unit price, and the standard selling price are displayed again in large size. When a predetermined time has passed after the sales data was displayed again, the message display timer 6 is activated again and the display on the main display is switched to a message.

When a customer, such as a member, who should receive preferential treatment comes, the member card is loaded into the card reader 32 and the preferential treatment degree set for this customer is read. As a result, the second unit price storage means 11 outputs the discounted unit price corresponding to this customer, and the discounted unit price is displayed small on the sub display 31 via the sub display driver 15. When the preparation is completed and the nozzle 26 is removed from the nozzle hook to start the liquid supply, the counting means 1 returns to zero and the liquid supply amount is newly added.
As a result, the standard unit price of the first unit price storage means 4, the liquid supply amount, and the charge when selling at the standard price are the main display 23.
It is displayed in large size. When the liquid supply is completed, the nozzle 26
When the payment button 35 is pressed after returning to the nozzle, the switch means 14 is turned on by the signal from the AND gate 13, and the product of the discount unit price calculated by the second charge calculating means 12 and the liquid supply amount, that is, the member charge. Is displayed small on the sub display 31. The salesperson charges the customer based on the fee displayed on the sub display 31. Needless to say, since the display area of the sub-display 31 is extremely smaller than that of the main display 23, other customers cannot see this member price.

When a predetermined time has passed since the nozzle switch 27 was turned off, a signal is output from the timer 6 and the message of the message storage means 5 is displayed on the main display 23.

In addition, when selling discounts to customers who do not have a card, the unit price rank button 34 on the panel 30 or the numeric keypad 33
By inputting the discount rank or the discount unit price from, the discount unit price is set in the second unit price setting means 11 and displayed on the sub-display 31. Thereafter, the member sale is performed in the same manner as described above.

In this embodiment, the liquid supply is stopped by stopping the pump, but it goes without saying that the same effect can be obtained even if the valve provided in the pipe line is closed.

(Effect) As described above, according to the present invention, the counting means for calculating the liquid supply amount based on the flow rate pulse from the flow rate detecting means,
A first unit price storage means, a second unit price storage means, a first rate calculation means for calculating a rate based on the data of the counting means and the first unit price storage means, the counting means and the second The second charge calculation means for calculating a charge based on the data in the unit price storage means, the main display for displaying the data from the counting means and the first charge calculation means, and the data from the second charge calculation means Since it has a sub-display that displays after the nozzle is hung on the nozzle hook,
