Next, a method of using the holding device for the oil supply nozzle will be described. First, the user informs the observer of the oil type (for example, high octane) using a microphone or the like. In response to this, the observer can operate the corresponding oil type selection means 9.

However, in this embodiment, means for automatically selecting the oil type of the vehicle is adopted, as shown in FIG. 4, when a vehicle enters from the entrance of the gas station. That is, for example, the data seal 32 is attached to both sides of the vehicle body 40. When the data seal 32 passes through the first detection sensor 7, the first detection sensor 7 Read. The data seal 32 contains readable oil type data of the company, and when the data is input from the first detection sensor, the oil type selecting means 9 sorts, for example, high-octane oil type. Next, the drive device 18 is operated by a signal from the unlock commanding means 10 of the designated oil type, the predetermined port of the valve V is switched, and the cylinder 26b is operated by the pneumatic pressure from the pneumatic source A to operate for high octane. The display is switched to a display in which the color or the character of the display window 8b can be used. At the same time, the air pressure transmitted to the head side of the cylinder 23b causes the piston 25b to retreat against the spring and retreat the rod 24b.

As a result, the trigger 5 of the high-octane refueling nozzle 4b is opened, and the fueling nozzle 4b is removed from the storage box 3b.
Is ready to be taken out. Thus, the refueling nozzle 4
Is normally locked and only the refueling nozzle 4 corresponding to the user's car is opened only when refueling.

In addition, since the color or the character displayed on the display window is switched and changed by the switching operation of the air pressure according to the signal, it is safe and the oil type can be confirmed, so there is no mistake.
Refueling operation can be performed with confidence.

Next, when refueling is completed and the vehicle moves, the second detection sensor 17 confirms the movement, and a signal from the locking command means 16 is transmitted to the driving device 18 to switch the switching valve V. Here, the air pressure supplied from the air pressure source A is cut off, the air cylinder 26b is returned by the action of the spring, and the display on the display window is switched to the original display indicating that it is unusable. At the same time, the cylinder 2 connected to the same pipeline
3b is also shut off, and the rod 24
b, the trigger 5 of the refueling nozzle 4b is inserted and the contact plate 15
a, the trigger 5 is locked, the operation becomes inoperable, and the refueling nozzle 4b is also in a state in which it cannot be taken out. The refueled oil amount is measured by a signal output from the refueling nozzle 4 and transmitted to the cash register room 41, and the cost corresponding to the refueling amount is settled when leaving. These payments can be made by a post system installed in the cash register room 41 or by a payment machine attached to the refueling base 2.

In addition to the refueling system described above, there is a monitoring staff at the gas station, and the monitoring staff operates the selection switch to release the lock of the refueling nozzle and transmit the fuel by the user by voice transmission from the user. You can also
Another use method is a method using a POS system. This method uses an unmanned POS system installed at a gas station.
By inputting the oil type selected by the user to the terminal, the lock of the corresponding oil type dedicated refueling nozzle can also be released. After the lock is released, a predetermined amount of refueling is performed by the user, the sensor confirms that refueling is completed and the fueling nozzle is returned to the original position, and the lock is locked after a predetermined time. Is also good.

In FIG. 6, the first detection sensor 7, the second detection sensor 17, and the data sticker 3
2 is explained in more detail. That is, when the data seal 32 of the vehicle body 40 is at the position A, the first detection sensor 7 does not operate, and at the position B1, the first detection sensor 7 reads the data of the data seal 32, and the lock is unlocked as described above. . Once the vehicle body 40 has passed the first detection sensor 7, it can be refueled at any position (position B 1). And when the user puts the refueling nozzle and takes out the car,
The data seal 32 is detected by the second detection sensor 17, and the refueling nozzle is locked by this detection.
Therefore, everything from unlocking to locking can be automatically performed.

FIG. 7 shows another embodiment, in which two types of data seals 33 and 34 are attached to a vehicle body 40. When the vehicle body 40 comes to the position I, the detection sensor 27 receives an unlock command signal from the data seal 34, the lock is unlocked, and the sensor can be used at the position II,
Next, when the refueling is completed and the vehicle comes to the position III, the detection sensor 27 receives a locking command signal from the data seal 33 and the lock is locked.
