For example, when the signal S is input once, the signal hy is output to urge the motor CI' to rotate forward, and the nozzle (c) is moved from the refueling standby position (double-dashed line position J in Figure 1) to the refueling time. While lowering to the position (5j! line position), the return zero signal (one pulse) i is fully output, and then another

4 Perform all operations to output signal b2. At this point, oil has not yet been refilled (oil is not flowing) and the pulse signal a has not yet been input, so the interval of the signal a is set to the value (0, 5 seconds) exceeds t-, so the signal passes through the judgment circuit (to) and reaches each control circuit (29 wheels).

y1 output output and judgment circuit - is refueled at this time, so the input interval of the pulse signal a is set by the circuit 6.
Since it is within the set value of 1), the passage of the signal is blocked and the reservation signal e (one pulse) TI- is output instead.

When it is output, since oil is not being refilled at this time, that is, the pulse signal a is not output, the interval of the pulse signal a naturally exceeds the setting value of the setting circuit 6υ, so the judgment circuit - is the signal bf. : Pass through control circuit 6'
J, - (at this time, signal e is not output). Then, the control circuit turns off the signal j if it is still being output (if the refueling is completed without outputting the signal my, the signal j is being output and the motor αQ is energized). On the other hand, the control circuit wheel outputs the signal h'H to the motor■? The nozzle (c) is energized in the reverse direction, and the nozzle (c) is raised to the refueling standby position and returned to its original state to wait for the next refueling.

きる。Although the switch is configured as described above, it does not have to be a single switch. For example, it may be a combination of up and down switches. In this case, which switch? The mechanism used to generate the reservation signal is good, and the motor α→ is not stopped by the signal m, but
The signal m may be used to completely close the solenoid valve installed in the oil pipe. Furthermore, when a signal is input once during refueling, the judgment circuit outputs a high reservation signal ef, and when the signal is input again, it outputs a signal to cancel all previous reservations (a reminder signal e'). It is also possible to output it and give it to a monitoring circuit.
