Abstract

A fuel supplying apparatus comprises a fuel supplying hose having a fuel supplying nozzle provided on a tip end thereof, a preset switch comprising a fuel supplying quantity preset switch and a fuel supplying price preset switch provided on the fuel supplying hose at a position in a vicinity of the fuel supplying nozzle, where the fuel supplying quantity preset switch is for selectively and sequentially presetting the predetermined quantity of fuel for preset quantity fuel supplying operation in response to the number of manipulation times of the switch and the fuel supplying price preset switch is for selectively and sequentially presetting the predetermined price of fuel for preset price fuel supplying operation in response to the number of manipulation times of the switch, an indicator unit for indicating either one of the preset quantity and the preset price preset by the preset switch, and a control circuit for presetting either one of the preset quantity or the preset price selected from the predetermined plural number of preset quantities and the predetermined plural number of preset prices, in response to the selective manipulation of either one of the fuel supplying quantity preset switch and the fuel supplying price preset switch as well as to the number of manipulation times of the selected switch. The indicator unit indicates the preset fuel quantity or the preset fuel price preset in the control device.

Claims

1. A fuel supplying apparatus comprising:

a fuel supplying hose having a fuel supplying nozzle provided on a tip end thereof;

preset switch means comprising a fuel supplying quantity preset switch and a fuel supplying price preset switch provided on said fuel supplying hose at a position in the vicinity of said fuel supplying nozzle, said fuel supplying quantity preset switch being a switch for selectively and sequentially presetting a predetermined quantity of fuel for preset quantity fuel supplying operation in response to the number of manipulation times of the switch, said fuel supplying price preset switch being a switch for selectively and sequentially presetting a predetermined price of fuel for preset price fuel supplying operation in response to the number of manipulation times of the switch;

indicating means for indicating either one of the predetermined quantity and the predetermined price preset by said preset switch means; and

control means for presetting either one of the preset quantity or the preset price selected from a predetermined plural number of prsest quantities and a predetermined plural number of preset prices, in response to the selective manipulation of either one of said fuel supplying quantity preset switch and said fuel supplying price preset switch as well as to the number of manipulation times of the selected switch, said indicating means indicating said preset fuel quantity or said preset fuel price preset in said control means,

said control means changing the fuel supplying mode from one of the preset quantity fuel supplying mode and the preset price fuel supplying mode to the other mode, during a fuel supplying operation, whereby said selective manipulation of one of said fuel supplying preset switches places said apparatus in the respective fuel supplying mode and said fuel supplying mode is changed, during said fuel supplying operation, when the other of said fuel supplying preset switch is manipulated.

2. A fuel supplying apparatus as claimed in claim 1 in which said control means discriminates which one of said fuel supplying quantity preset switch and said fuel supplying price preset switch is manipulated, and sequentially presets the fuel quantity or the fuel price in response to the number of manipulation times of said respective preset switch.

3. A fuel supplying apparatus as claimed in claim 1 in which said indicating means comprises a first indicating part in which predetermined plural number of numerals representing the preset quantities are aligned in a row, a second indicating part in which predetermined plural number of numerals representing the preset prices are aligned in a row, the respective numerals of the first indicating part and the respective numerals of the second indicating part being located so as to form a pair with each other, a first indication means located in correspondence with respective numerals of said first and second indicating parts, and a second indication means respectively located in said first and second indicating parts, a control circuit makes the indicating means indicate either of said first or second indicating parts, by means of said second indication means, in response to the manipulated one of the fuel supplying quantity preset switch and said fuel supplying price preset switch, and the numerals which are successively and selectively preset, by said first indication means, in response to said number of manipulation times of the manipulated preset switch.

4. A fuel supplying apparatus as claimed in claim 3 in which said first indication means comprises plural indication lamps which are aligned in a row between the numerals of said first indicating part and the numerals of said second indicating part which are arranged to make pairs with each other, said second indication means comprises two indication lamps which are provided in said first and second indicating parts, said indication lamps of said first indication means sequentially turning on in response to the number of manipulation times of said preset switch and indicating the corresponding numerals of said first and second indication parts, and the indication lamp of said second indicating means being turned on in response to one of the preset switches which is manipulated.

5. A fuel supplying apparatus as claimed in claim 1 which further comprises a structure, an elevator mechanism provided on said structure for raising and lowering said fuel supplying hose and said fuel supplying nozzle which are suspended from said structure, and an elevator switch for driving said elevator mechanism, said preset switch means and said elevator switch being respectively provided on said fuel supplying hose at positions in the vicinity of said fuel supplying nozzle.
