Claims (1)

[Scope of Claim for Utility Model Registration] In a refueling device equipped with an automatic refueling stop function that stops refueling by stopping the supply of oil from the pump to the nozzle when the amount of refueling to the vehicle tank reaches full, A liquid level detection means for detecting the liquid level in a vehicle tank, a tax unit price setting means for setting a tax unit price of oil, a tax rate setting means for setting a tax rate, and a unit for setting an integer unit. an integer unit setting means; a flow rate pulse transmitter attached to a flow meter that measures the amount of oil supplied; a quantity calculating means that calculates the amount of supplied oil based on the flow rate pulse of the flow rate pulse transmitter; a flow rate pulse detection means for detecting a stoppage of the flow rate pulse or an irregular state of the pulse interval; and a pump motor for stopping a pump motor that drives and controls the pump when the liquid level detection means detects a liquid level in the vehicle tank. normal drive control means; when the flow rate pulse detection means detects a stoppage of the flow rate pulse or an irregular state of the pulse interval after the pump motor is stopped by the pump motor normal drive control means, the pump motor is stopped and then the pump motor is stopped; an overflow calculation means for calculating a refueled overflow amount; and an overflow calculation means that adds the oil supply amount calculated by the oil supply amount calculation means before the stop of the pump motor and the overflow amount, and calculates the added amount, the tax unit price, and the overflow amount. tax-inclusive refueling amount calculation means for calculating the tax-inclusive refueling amount based on the tax rate; and integer amount setting for setting an integer amount by adding an integer unit by the integer unit setting means to the tax-included refueling amount calculated by the tax-inclusive refueling amount calculation means. means, converting the tax-included difference obtained by subtracting the tax-inclusive refueling amount from the integer amount set by the integer amount setting means into a tax difference based on the tax rate; additional oil supply amount setting means for setting the additional oil supply amount setting means; limit amount determination means for determining whether or not the additional oil supply amount set by the additional oil supply amount setting means is within a preset limit amount; and the limit amount determination means. A pump motor minute drive control means for slightly driving the pump motor to supply the additional amount of oil that can be supplied when the means determines that the amount of additional oil that can be supplied is within a limit amount.
