【考案の詳細な説明】 本考案は給油装置に関するものである。[Detailed explanation of the idea] The present invention relates to a refueling device.

つて変更されることがしばしばある。 In order to provide refueling information to customers and improve the efficiency of refueling operations, refueling devices used at gas stations usually display the amount of refueling, the unit price of refueling, and the amount of refueling. In this case, the refueling unit price, which is the standard for calculating the refueling amount, is normally set using a unit price setting device installed at an appropriate location in the refueling device, but this set unit price varies depending on the day (for example, distinguishing between weekdays and holidays). It is often changed by the time of day or by the customer.
一方給油装置においては、前回の給油における
給油量および給油金額は次回の給油を開始するま
では表示され続けるのが普通である。従つて前回
の給油量および給油金額が表示されている間に単
価が変更されてこの変更された単価が表示される
と、変更単価と表示給油量との積が表示給油金額
と一致しなくなつて不都合である。 On the other hand, in a refueling device, the amount of refueling and the amount of refueling for the previous refueling are usually continuously displayed until the next refueling is started. Therefore, if the unit price is changed while the previous refueling amount and refueling amount are displayed, and this changed unit price is displayed, the product of the changed unit price and the displayed refueling amount will no longer match the displayed refueling amount. This is inconvenient.
この考案は上記のような不都合が生じないよう

ある。 In order to prevent the above-mentioned inconvenience from occurring, this idea is designed so that when the refueling amount from the previous refueling is displayed, if the refueling unit price is changed while not refueling, the refueling amount will be reset to zero. This is what I did. That is, the device of this invention includes a nozzle detection switch that generates a nozzle signal L when the refueling nozzle is placed in the non-refueling position and generates a nozzle signal H when the refueling nozzle is moved from the non-refueling position to the refueling position, and a refueling unit price. A fuel supply unit price setting circuit that generates a corresponding unit price signal a, a unit price display that displays the set unit price, a pulse transmitter that outputs a flow rate pulse P every time a unit oil amount is measured, and a pulse generator that counts the flow rate pulse. A counting circuit, a refueling amount display that displays the counted value of the counting circuit as the refueling amount, an arithmetic circuit that calculates the refueling amount based on the set refueling unit price signal and the flow rate pulse, and a refueling amount display that displays the refueling amount. In the refueling device, the unit price setting signal a is sent to the calculation circuit while the nozzle signal H is output. input of the unit price signal a is blocked while the nozzle signal L is being output.
A determination circuit is also provided which generates a signal b which, when received, returns the calculated value of the arithmetic circuit to zero.

信号ａが演算回路に入力されるのを阻止する。従
つて、給油の進行に応じて前回設定された単価に
基づいて給油金額が算出表示される。 When the refueling nozzle is removed from the nozzle case, nozzle signal H is input to the judgment circuit, and even if the unit price is changed in this state and signal a is generated, the judgment circuit blocks this signal a from being input to the calculation circuit. do. Therefore, as refueling progresses, the refueling amount is calculated and displayed based on the previously set unit price.

が、給油量表示器の表示値は変らない。 When the refueling nozzle is returned to the nozzle case, a signal L is input to the determination circuit. When the unit price is changed in this state, the judgment circuit generates signal b, and this signal causes the calculated value of the calculation circuit (refueling amount for the previous refueling) to return to zero, and the display on the refueling amount display becomes zero. . At this time, the unit price display displays the changed unit price, but the displayed value on the oil supply quantity display does not change.

回路１７によつて表示器７ｃに表示される。 When a refueling unit price is set by the unit price setter 13, a unit price signal a corresponding to this unit price is stored in the storage circuit 15 via the determination circuit 14 under conditions described later in place of the previously stored unit price. . This memorized unit price is given to the arithmetic circuit 16 and displayed on the display 7c by the display drive circuit 17.

１５への入力を阻止する。 When the nozzle 9 is removed from the nozzle case 10, the nozzle detection switch 11 outputs the nozzle signal H as described above.
This signal H energizes the motor 4 via the motor control circuit 18 and also energizes the counting circuit 1.
9. The arithmetic circuit 16 is reset, and even if the refueling unit price is changed by the unit price setter 13 by being applied to the determination circuit 14, the changed unit price is prevented from being input to the storage circuit 15.

表示される。 When the nozzle 9 is operated to start refueling, a flow rate pulse P corresponding to the amount of refueling is given to the counting circuit 19, and the counting output is sent to the display 7 via the display drive circuit 20.
Display the refueling amount on a. The flow rate pulse P is also given to the arithmetic circuit 16, and the refueling unit price from the memory circuit 15, that is, the unit price for one pulse P, is integrated every time the pulse P is input, and the integrated output is sent to the display drive circuit 21. The amount is displayed on the display 7b as the refueling amount.
既述のように、ノズル信号Ｈが判定回路１４に
与えられている間に単価設定器１３において単価
が変更されても判定回路１４は変更単価を記憶回
路１５へ与えることはしないので、当該給油操作
に混乱は生じない。 As described above, even if the unit price is changed in the unit price setter 13 while the nozzle signal H is being given to the judgment circuit 14, the judgment circuit 14 does not give the changed unit price to the storage circuit 15, so that the relevant refueling There is no confusion in operation.

算値すなわち給油金額）を帰零する。従つて表示
器７ｂの表示（前回給油金額）も帰零される。 When refueling is completed and the nozzle 9 is returned to the nozzle case 10, the nozzle signal H becomes L. When the unit price is changed in the unit price setter 13 in this state, the determination circuit 14 supplies a new unit price signal a to the storage circuit 15 to store it in place of the old unit price, and also generates an output signal (one pulse) b. do. This signal b is given to the arithmetic circuit 16, and its contents (the calculated value at the time of previous refueling, that is, the refueling amount) are returned to zero. Therefore, the display (previous refueling amount) on the display 7b is also reset to zero.
表示器７ａには前回給油量が表示されたままで
残つており、また表示器７ｃには新単価が表示さ
れているが、表示器７ｂには給油金額がＯと表示
されているので前述の不都合はない。 The previous refueling amount remains displayed on the display 7a, and the new unit price is displayed on the display 7c, but the refueling amount is displayed as O on the display 7b, which causes the above-mentioned inconvenience. There isn't.
なお、判定回路１４からの信号ｂを第２図に破
線で示すように計数回路１９にも与えてこれを帰
