), 'In Fig. 8, the preset amount setting means 38
As shown in FIG. 12, the count value TB of the timer 41 is initially 50 m5ec (to prevent chattering).
Afterwards, the preset data stored in the corresponding address is read out from the storage means 33 and set, and the preset data is displayed on the preset display 21, as shown in FIG. 11. Display (step S55...).

Then, when the step number reaches tlo, the process starts again from tl.

Note that the lamp 21b is lit when displaying the amount, and the lamp 21c is lit when displaying the amount.

By the time the preset switch is turned on like this,
A desired preset amount can be easily set.

In FIG. 9, during refueling, the comparison means 45 always determines whether the amount of oil supplied from the counting calculation means 39 (see FIG. 3) is equal to the set value of the preset amount setting means 38 (step 560), and the answer is YES. When this happens, a valve closing signal is output to the control valve 19 to close it (step 561).

D. Integer lubrication In Fig. 10, when normal lubrication is interrupted and the integer lubrication switch 9 is pressed (Stella 7S30), the u number lubrication judgment means 4
3, it is determined whether or not preset lubrication is stored in the storage means 34 (step 531); in this case, it is normal lubrication (if preset lubrication is stored, it is ignored); 9, during next lubrication; It is determined whether or not refueling is being stored in the determining means 36 (step 532). In this case, since refueling has been interrupted, refueling is not stored, and then the integer quantity calculation means 44 is already storing the amount of money. It is determined whether integer lubrication has been performed (step 333) or whether integer lubrication has been performed based on the amount (step 535). At this stage, it is the first integer refueling, so the amount at the time of interruption will be, for example, 3.
If it is 363 yen and the lower digit is 70 yen, round it up to 100 yen and get 3,400 yen. For example, if it is 3,383 yen or more, round it up to 200 yen and convert it to 3,500 yen, and calculate the planned stoppage refueling amount. is set in the preset amount setting means 38 and displayed on the preset amount display 21 (step 33
7) When performing integer lubrication by quantity, when the integer switch 11 is pressed again (step 838), the integer quantity calculation means 44 calculates that the lubrication quantity at the time of interruption is, for example, 28.036, with one decimal place less than 7. In the case of , round up to 1g and set it as 29j2, 2
8.8372, if one decimal place is 0.72 or more, round up to 2g and convert it to an integer as 30ff, set the scheduled stop amount in the preset amount setting means 38, and display it on the preset amount display meter 21. (Step 340), and each time the integer switch 9 is pressed in this way (Step S41.
33g), the amount integer and the amount integer are set and displayed alternately.

If you restart refueling after setting, it will be refueling (step 3).
39.542), when the set amount is reached, the valve is closed according to the flow shown in FIG. 9, and refueling is stopped.

In addition, when integer refueling is performed and further refueling is possible, when the integer switch 9 is pressed again, the integer amount calculation means 44, through steps S30 to 332, determines whether or not the amount was previously set as an integer. If YES, then perform the next calculation to convert the amount into an integer, set it in the preset amount setting means 38, and display it on the preset amount display 21 (Step 534), if No, the amount was set as an integer. Therefore, step S35 becomes YES, and step S33
At G, a calculation is performed to convert the quantity into an integer, and the result is displayed on the preset display 21.

[Summary] As explained above, according to the present invention, when refueling is resumed by pressing the integer switch after refueling is interrupted, the scheduled stop refueling amount is displayed in the amount or amount on the preset amount display. Therefore, the customer can prepare N3 yen by looking at the display, and as a result, the payment process is carried out smoothly, which is convenient for both the customer and the gas station.
