output to a.

Note that the configuration of the control section 42 of the oil supply device 21 is also the same as the configuration described above, and a description thereof will be omitted.

Next, the operation of the first embodiment with the above configuration will be explained.

For example, first, vehicle A, which has a fuel filler port on the right side with respect to the vehicle traveling direction, uses the fuel filler 20 at the fuel filler point P2.
Regular refueling shall be provided for the following reasons.
Worker A uses the refueling nozzle 22 that corresponds to the regular.
When A is removed from the nozzle hook and refueling work is started to insert it into the fuel filler port of vehicle A, the nozzle switch 22a is closed and a "1" signal is sent to the monomulti 50 and the OR gate 53, and a "0" signal is sent to the monomulti 52. As a result of each new supply, monomulti 50
A trigger pulse is supplied to AND gate 60 only from . At this time, if the refueling nozzle 24B is returned to the nozzle hook, the nozzle switch 24b will close when the refueling nozzle 24B is returned, and the monomulti 5
Since the RS flip-flop 63 is reset via the RS flip-flop 6, the AND gate 60 is supplied with the output "1" of the RS flip-flop 63. As a result, the trigger pulse from the monomulti 50 is passed through the AND gate 60 to the RS
It is supplied to the set input terminal S of the flip-flop 61, and the Q output of the RS flip-flop 61 is "1".
Then, the control valve 26a opens, and a reset pulse is supplied to the reset input terminal R of the oil supply amount calculation circuit 66 via the OR gate 64 and the monomulti 65, and the oil supply amount calculation circuit 66 and the display 45a are reset to zero. . At this time, the pump 27 is already in the driving state because the close signal "1" of the nozzle switch 22a is supplied to the drive circuit 59 via the OR gate 53, so the pump 27 is connected to the vehicle A.
When inserted into the fuel filler port and opened the valve, the regular fuel will be filled into the fuel tank of vehicle A. Along with this refueling, a flow rate pulse signal output from the flow rate pulse transmitter 29A corresponding to the flow rate passing through the flow meter 28A is transmitted to the refueling amount calculation circuit 6 via the OR gate 58.
6 and is counted, and the count value of the calculation circuit 66, that is, the vehicle A
The amount of oil supplied is displayed on the display 45a.

Next, a case will be described in which, while the vehicle A is being refueled, a vehicle B, which has a refueling port on the left side with respect to the vehicle traveling direction, comes in to receive light oil refueling. At this time, worker B guides vehicle B to refueling point P3 and operates refueling nozzle 24A to perform refueling work. As a result, the same control as described above is performed in the fuel supply device 21, and light oil is supplied to the vehicle B from the fuel supply nozzle 24A.

On the other hand, during the refueling of the vehicle A, instead of the vehicle B, a vehicle B' of the same liquid type, which has the refueling port on the right side with respect to the direction of vehicle travel like the vehicle A, receives regular refueling. Let me explain what happens when you come in. At this time, the oil supply devices 20, 21
Instead, at a refueling station where conventional single-type refueling equipment was installed, one for regular and one for light oil, vehicle B' could not be refueled until vehicle A had finished refueling. Worker B guides vehicle B' to an empty refueling point P4 that matches the position of the refueling port. and,
Worker B removes the refueling nozzle 22B corresponding to the regular from the nozzle hook of the refueling device 21,
Vehicle B′ is refueled. This case will be explained below.

Regarding the refueling device 21, when the worker B starts refueling work by removing the refueling nozzle 22B corresponding to the regular from the nozzle hook and inserting it into the refueling port of the vehicle B', the nozzle switch 22b closes and the monomulti 54 and the As a result of newly supplying a "1" signal to the gate 57 and a "0" signal to the monomulti 56, a trigger pulse is supplied only from the monomulti 54 to the AND gate 62. At this time,
If the refueling nozzle 24A is returned to the nozzle hook, the nozzle switch 24a will close when the refueling nozzle 24A is returned, and the RS will be connected via the monomulti 52.
Since the flip-flop 61 has been reset, the output "1" of the RS flip-flop 61 is supplied to the AND gate 62. As a result, the trigger pulse from the monomulti 52 is supplied to the set input terminal S of the RS flip-flop 63 via the AND gate 62, and the RS
The Q output of the flip-flop 63 becomes "1", the control valve 26c opens, and the OR gate 64,
A reset pulse is supplied to the reset input terminal R of the oil supply amount calculation circuit 66 via the monomulti 65, and the oil supply amount calculation circuit 66 and the display 45 are reset to zero. At this time, the closing signal "1" of the nozzle switch 22b is the Q of the RS flip-flop 63.
By outputting “1”, AND gate 5
7. The signal is outputted from the oil supply device 21 to the signal connection end 41 of the oil supply device 20 via the signal connection end 43 and the cable 44. As a result, in the oil supply device 20, the closing signal “1” of the nozzle switch 22b from the oil supply device 21 is supplied to the drive circuit 59 via the OR gate 53, and the pump 27 is driven. Therefore, when the refueling nozzle 22B is inserted into the refueling port of the vehicle B' and the valve is opened, the regular discharged from the pump 27 of the refueling device 20 is transferred to the liquid feeding connection end 34 of the refueling device 20, the piping 38, and the refueling device 21. The liquid is supplied to the nozzle 22B through the liquid receiving connection end 35 of the vehicle.
The regular is refueled into the B' refueling tank.
Along with this refueling, the flow rate pulse transmitter 29
A flow rate pulse signal outputted corresponding to the flow rate passing through the flowmeter 28B from B is transmitted from the oil supply device 20 to the oil supply device 2 via the signal connection end 41 and the cable 44.
The signal is output to the signal connection end 41 of No. 1. This results in
In the refueling device 21, the flow rate pulse signal from the flow rate pulse transmitter 29B is supplied to the count input terminal of the refueling amount calculation circuit 66 via the OR gate 58 and counted, and the refueling amount for the vehicle B' is determined by the calculation circuit 66. is displayed on the display 45a as a count value.

Moreover, regarding the end of refueling, when each worker A, B returns the refueling nozzle 22A, 22B to the nozzle hook at any time, each control valve 26a, 26c closes,
The pump 27 does not stop until both nozzles 22A and 22B are returned to the nozzle hook.

Note that the same control as above is performed when refueling a vehicle at another refueling point with a desired liquid type in the same manner as above.
