A lubrication device with a total lubrication function, which is provided with two lubrication systems including the other lubrication system including a pump / flow meter / flow rate pulse transmitter / control unit and the like, is known. When using both refueling nozzles of both refueling systems of this type of refueling device, for example, when performing total refueling for a vehicle equipped with two fuel tanks, the refueling operator inserts both refueling nozzles into each fuel tank, Open the levers of both refueling nozzles to start refueling. Then, along with the total refueling, the control unit of the refueling system on one side of the refueling device causes the refueling amount pulse signal corresponding to the total refueling amount to each of the two fuel tanks by each refueling nozzle, and the one side refueling system. A refueling signal is sent to the POS body inside the gas station building. Further, the control unit of the refueling system on the other side transmits the amount of refueling by the refueling system of the other side to the control unit of the refueling system on the one side, and sends the signal during refueling of the refueling system on the other side to the POS body. It is designed to be sent to.

Regardless of, the refueling signal is turned off.

[Problems to be solved by the device]

By the way, in the conventional refueling device, when the total refueling is performed, the control unit of one refueling system sends the refueling amount pulse signals for two refueling nozzles to the POS main body, so it takes time to send the refueling amount pulse signal. Therefore, there may be a case where the refueling amount pulse signal is still being sent to the POS body even after the refueling of the predetermined refueling amount is completed. However, when the refueling operator returns the refueling nozzle to the nozzle housing while the refueling amount pulse signal is being sent, the nozzle switch turns off and the refueling signal also turns off. The refueling amount or the like corresponding to the refueling amount pulse signal up to the point of time is printed and issued on the slip by the printer. However, since the refueling amount pulse signal is sent from the refueling device even after the refueling signal is turned off, the actual refueling amount to the vehicle by both refueling nozzles does not match the refueling amount printed on the slip. There was a problem. The present invention solves the above-mentioned problems, and an object of the present invention is to provide a refueling device that achieves matching between the actual refueling amount for a vehicle and the refueling amount printed on a refueling slip.

First nozzle detecting means, and second nozzle detecting means for detecting attachment / detachment of the oil supply nozzle of the second oil supply system to the nozzle housing portion,
At the time of refueling, in the state where the total refueling setting means for setting the total refueling by the refueling nozzles of the both refueling systems and the total setting by the total refueling setting means, the first nozzle detecting means and the second nozzle detecting means store the nozzles. When it is detected that the refueling nozzle is detached from the section, a refueling signal is sent to the POS main body for the detected refueling system, and the first nozzle detecting means and the second nozzle detecting means are used to supply the refueling nozzle to the nozzle housing section. When the storage of is detected, the refueling signal control means for deactivating the refueling signal being sent to the POS main body for the detected refueling system, and the summed refueling setting means in the state where the summation setting is made, The refueling pulse corresponding to the refueling amount refueled by the refueling nozzle of the refueling system is used for refueling by either the first or second refueling system.

An oil supply amount signal is sent from the oil supply device to the POS body. After the refueling work is completed, even if the refueling operator returns one of the refueling nozzles or both refueling nozzles to the nozzle accommodating section, the sending of the refueling signal is not stopped, and after the refueling device has finished sending the refueling amount signal to the POS body. The sending of the signal during refueling is stopped.

It is designed to be sent to the POS main body 2 via the S oil supply amount signal line S2. Next, the operation of this embodiment having the above configuration will be described with reference to FIG. For example, when refueling the same vehicle equipped with two fuel tanks with both refueling systems A and B, the refueling operator sets the total refueling from the total refueling setting unit 9 before refueling. Next, time t1
When the refueling operator removes the refueling nozzle on the refueling system A side from the nozzle housing, the nozzle switch 4A turns on and the pump motor operates, and the refueling signal control circuit 5A outputs the refueling signal to the POS main body 2.
