That is, a nozzle equipped with an integer refueling function and a preset refueling function is provided with a nozzle elevating switch 31, a reset switch 32, an integer refueling switch 33, and a preset refueling switch 34 (Fig. 9A), and only normal refueling is possible. In this case, a nozzle elevating switch 31 and a reset switch 32 are provided (Fig. 2B). These switches 31, 32, 33,
34 is a cable 3 provided along the refueling hose 5.
It is connected to the nozzle raising / lowering control means 18 and the control panel 20 via 5. Reference numeral 36 in the figure denotes a cable connecting the hand-held indicator 10 and the control panel 20.

Next, in the apparatus constructed as described above, 3
The operation of registering and updating the basic data using one switch will be described with reference to the flowchart shown in FIG. (Basic data registration mode) When a refueling device is newly installed or when basic data needs to be changed, the changeover switch 24 provided on the control panel 20 is operated to select a registration operation. .

When the nozzle raising / lowering switch 31 of the hand switch 30 is pressed in this state (step B), the nozzle raising / lowering control means 18 causes the hose reel motor 7 to rotate in the forward direction to lower the refueling nozzle 8. When the nozzle 8 is pulled out to a position where oil can be supplied (step C), a signal is output from the nozzle position detection means 9, so that the nozzle elevation control means 1
8 stops the hose reel motor 7 (step
D).

In the present case, since the registration mode is selected by the changeover switch 24 (step E), the registration data control means 23 causes the registration data control means 23 to register the machine number data, the oil type data, and the unit price. Basic data such as data is read and sequentially output to the hand-held display 10.

When the data is stored in the storage means 22, as shown in FIG. 6, the machine number item "1" 41, the oil type item "2" 42, and the unit price item "3" 43 are displayed. It is sequentially displayed on the hand display 10 (step F). Then, the lowest digit 41a of the displayed first item "1" 41 blinks and is displayed as a numerical value that can be registered or updated (step).

In this state, the preset oil supply switch 34
Every time the button is pressed (step E), 1 is added to the displayed numerical value, "1" in this embodiment (step W), and when it becomes "9", "0" is displayed again. When the integer refueling switch 33 is pressed at the stage where the numerical input of the lowest digit 41a is completed in this way (step
Re), in this case it is not the most significant digit (step
The flashing position is shifted to the second digit 41b of the item "1" (step, g). When the preset refueling switch 34 is pressed in this state (step E), 1 is added to the numerical value "0" that is being displayed, as described above.

By repeating the above operation, the most significant digit 41d
When the correction is advanced to (Step N), since the second and third items 42 and 43 still remain (Step K), the second item "2" 42 is displayed and the first digit 42a blinks. (Step Yo, To).

Every time the preset lubrication switch 34 is pressed in this state (step E), 1 is added to the numerical value "1" of the first digit 42a displayed in the blinking state (step WA), and the integer lubrication switch 33 Each time you press (step step), the digit shifts to the upper position (step step,
Le).

To partially correct a specific digit without modifying all digits of the item "2" 42, press the reset switch 32 before the blinking position reaches the most significant digit (step H). , In the present case, the third item "3" 4
Since 3 remains (step F), the next item, that is, the third item “3” 43, is displayed, and the first digit 43 a of flickers (step Y).

When the reset switch 32 is pressed when the correction of the final item 43 is completed (step
H) Since all three items have been corrected (step C), the registration loop is exited and the pressing of the elevating switch 31 is waited (step T). The basic data input in this way is registered and updated in the storage means 22.

When the elevating switch 31 is pressed (step), the nozzle elevating control means 18 drives the hose reel motor 7 to wind up the hose 5. When the nozzle 8 reaches the rising limit position (step S), a signal is output from the nozzle position detecting means 9 and the hose reel motor 7 stops (Step S). Then, the changeover switch 24
Is switched from the registration operation to the refueling operation.

(Refueling Mode) When the elevating switch 31 of the hand switch 30 is pressed (step a), the refueling control means 21 reads out the machine number data, the oil type data, and the unit price data from the storage means 22 and stores them in the POS 26. Output. The POS 26 outputs a refueling permission signal to the control panel 20 when these data are input. As a result, the nozzle elevation control means 18 causes the hose reel motor 7 to rotate normally (step S). When the fueling nozzle 8 reaches the fueling position, a signal is output from the nozzle position detecting means 9 (step C). Therefore, the nozzle elevating control means 18 stops the hose reel motor 7 (step D) to turn the nozzle 8 on. Stop the refueling position and execute the refueling control operation (step S).

That is, when the refueling lever is pulled without operating any of the hand switches 30, normal manual refueling is executed, and the integer refueling switch 3 is operated after refueling is stopped.
When 3 is pressed, additional refueling is executed until the fraction of the current refueling amount reaches a good cut value.

Further, when refueling is performed after the preset refueling switch 34 is pressed, the stop valve 13 is closed and the refueling is stopped when the preset refueling amount is reached.

While refueling is being performed in this manner,
A flow rate pulse is output from the flow rate pulse transmitter 16. This flow rate pulse is output to the refueling control means 21 via the refueling control means 17, is displayed as the refueling amount on the refueling amount display 27 and the hand display 10 which are installed at positions that are easy to see, and is also output to the POS 26. It

When the nozzle raising / lowering switch 31 of the hand switch 30 is pressed after refueling is completed, the nozzle raising / lowering control means 18 reverses the hose reel motor 7 to wind the hose 5 and raise the nozzle 8. The POS 26 is activated by a signal generated by pressing the nozzle elevating switch 31.
Issues a refueling slip by performing data processing based on the refueling amount and unit price data.

When the oil is continuously replenished without raising the nozzle 8, the reset switch 32 is used.
By pressing, a new refueling is possible while the refueling slip is issued based on the previous refueling amount.

In the above-mentioned embodiment, the case where the basic data is registered and updated by using the three switches has been described, but even if two of the four switches, for example, the reset switch 32 and the integer refueling switch 33 are used. Basic data can be registered and updated. This operation will be described based on the flowchart shown in FIG.

That is, when registering the basic data, the registering operation is selected by the changeover switch 24. In this state, when the nozzle raising / lowering switch 31 of the hand switch 30 is pressed (step a), the nozzle raising / lowering control means 18
Causes the hose reel motor 7 to rotate normally and lower the nozzle 8. When the nozzle 8 is pulled out to the refuelable position (step C), a signal is output from the nozzle position detection means 9, so the nozzle elevation control means 18 stops the hose reel motor 7 (step D).

In this case, since the registration mode is selected (step E), the registration data control means 23 reads the basic data registered in the storage means 22 and sequentially outputs it to the hand display unit 10.

The machine number item "1" 41, the oil type item "2" 42, and the unit price item "3" stored in the storage means 22.
43 are sequentially displayed on the hand display 10 (step
F). Then, the lowest digit 41a of the displayed first item "1" 41 is displayed in a blinking state (step).

In this state, each time the integer refueling switch 33 is pressed (step), 1 is added to the displayed numerical value "1" (41a) (step o),
When it becomes "9", "0" is displayed again. When the reset switch 33 is pressed at the stage where the numerical input of the lowest digit 41a has been completed in this way (step), since it is not the highest digit in this case (step), the blinking position is the second digit. Shift to digit 41b (Step Nu,
G). When the integer refueling switch 33 is pressed in this state (step), 1 is added to the currently displayed numerical value "0" as in the above (step o).

By repeating the above operation, the most significant digit 41d
When the correction is advanced to (step), the second and third items 42 and 43 still remain (step w), so the second item 42 is displayed and the first digit 42a thereof blinks (step). F).

In this state, every time the integer refueling switch 33 is pressed (step), 1 is added to the displayed numerical value (step o), and each time the reset switch 32 is pressed (step h), the digit is changed. Shift to a higher position (stepping, nu).

In this way, when the reset switch 32 is pressed while the highest digit has been reached by shifting the digits by the reset switch 32 (step, re), the third item "3" 43 still remains in this case. Therefore, the third item “3” 43, which is the next item, is displayed, and the lowest digit 43a blinks. When the correction of the last item "3" 43 is completed (step W), the registration mode is exited.

When the elevating switch 31 is pressed (step yo), the nozzle elevating control means 18 drives the hose reel motor 7 in reverse (step step) to wind up the hose 5. When the nozzle 8 reaches the rising limit position (step), a signal is output from the nozzle position detection means 9 and the hose reel motor 7 stops (step S). When the changeover switch 24 is switched to the refueling operation, the refueling operation and the data processing are subsequently executed based on the new basic data.

FIG. 8 shows that the present invention uses only an oil supply device provided with a nozzle elevating switch 31 and a reset switch 32 as shown in FIG. 4B, or using only two switches out of four hand switches. 10 is a flowchart showing an example of a case of registering by performing the registration.

When registering basic data, the control panel 20
The registration operation is selected by the changeover switch 24 of. In this state, when the nozzle raising / lowering switch 31 of the hand switch 30 is pressed (step a), the nozzle raising / lowering control means 18
Rotates the hose reel motor 7 forward (step
(B) Lower the nozzle 8. When the refueling hose 5 is pulled out to the position where the nozzle 8 can be refueled (step C), a signal is output from the nozzle position detection means 9, so that the nozzle lifting control means 18 stops the hose reel motor 7 (step D).

In this case, since the registration operation is selected by the changeover switch 24 (step E), the registration control means 23 reads the basic data registered in the storage means 22 and sequentially displays it on the hand display 10. Output.

The machine number item "1" 41, the oil type item "2" 42, and the unit price item "3" stored in the storage means 22.
43 are sequentially displayed on the hand display 10 (step
F). Then, the lowest digit 41a of the displayed first item "1" 41 is displayed in a blinking state (step).

In this state, each time the reset switch 32 is pressed (step), 1 is added to the numerical value "1" of the blinking digit 41a (step o),
When it becomes "9", "0" is displayed again. If the nozzle up / down switch 32 is pressed (step) at the stage where the numerical input of the lowest digit 41a is completed in this way (step), the blinking position is the first digit because it is not the highest digit (step). Shift to the second digit 41b (Stepnu).
When the reset switch 32 is pressed in this state (step S), 1 is added to the numerical value “0” currently displayed (step S) as described above.

By repeating the above operation, the most significant digit 41e
When the correction is advanced to (step), the second and third items 42 and 43 still remain (step W), so the second item "2" 42 is displayed and the first digit 42a of that item blinks. Yes (step power).

In this state, each time the reset switch 32 is pressed (step), 1 is added to the displayed numerical value (step o), and each time the elevating switch 31 is pressed (step h), a blinking digit is displayed. Shifts to a higher position (Stepri, Nu).

In this way, when the reset switch 32 is pressed at the stage where the highest digit is reached by the digit shift by the elevating switch 31 (step, re), in this case, the third item "3" 43 still exists. Is left (step W), the third item “3” 43 is displayed, and the least significant digit 43a thereof blinks. And the last item "3" 43
When the correction in step is completed (step W), exit the registration mode.

When the elevating switch 31 is pressed (step yo), the nozzle elevating control means 18 reverses the hose reel motor 7 (step) and winds the hose 5. When the nozzle 8 reaches the upper limit position (step
Then, a signal is output from the nozzle position detection means 9 and the hose reel motor 7 is stopped (step step). And
When the registration operation is switched to the refueling operation by the changeover switch 24, the data processing is subsequently executed based on the new basic data.

In the above embodiment, the digit shift is made to shift from the lower digit to the upper digit, but it is clear that the same effect can be obtained by shifting the digit from the upper digit to the lower digit. .
