  Next, an embodiment for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an embodiment of a display (hereinafter referred to as “display”) of a suspended oil supply apparatus according to the present invention. The display 1 includes a main body 2 having an open front surface, and a front surface of the main body 2. The window frame 3 provided in the window 2, the glass plate 4 supported by the window frame 3 and closing the opening on the front surface of the main body 2, the display unit 5 disposed inside the main body 2, and the display of the display unit 5 are controlled. The control board 6, the fluorescent lamp 7 provided in the lower part inside the main body 2 for improving visibility, the mounting portion 8 provided on the back surface of the main body 2, etc. Is displayed above the refueling worker.

  The display unit 5 is composed of seven liquid crystal display elements combined in a Japanese character shape. Thereby, durability can be improved rather than the case where a display part is comprised with a mechanical display element. Further, since the display unit 5 is composed of a liquid crystal display element, the display unit and the display unit are not tilted at a tilt angle as in the case of a mechanical type, and the display unit 1 is attached to be tilted downward, It is possible to adjust the inclination angle of the part 5 with respect to the main body 2 and to attach the display part 5 so as to be inclined downward. The display unit 5 uses the VA (Vertical Alighnment) formula to make the background of the LCD black and apply light from the back to display the display character part in white or color (negative display). The light shielding property can be greatly improved, which is preferable.

  Further, the display unit 5 includes a backlight (not shown), and the backlight and characters to be displayed use LEDs of three colors of red, yellow, and green as light sources, and the emission color is controlled by the control board 6. It emits light in various colors.

  The main body 2 is provided with an illuminance meter (not shown) for measuring the illuminance around the display unit 5, and the illuminance meter is electrically connected to the control board 6.

  Next, the operation of the display 1 having the above configuration will be described with reference to FIGS.

  In step S1, when the nozzle lowering switch (SW) of the suspension type fueling device is pressed (step S1: Yes), the fueling nozzle is lowered and the display unit 5 maintains the extinguished state (step S2). In step S1, when the nozzle lowering SW is not pressed (step S1: No), the process waits until the nozzle lowering SW is pressed.

  In step S3, it is determined whether or not the fueling nozzle has been lowered to the fueling position. If the fueling nozzle has been lowered to the fueling position (step S3: Yes), the fueling nozzle is stopped from being lowered and the display unit 5 returns to zero. Is displayed and the oil supply pump is activated (step S4). On the other hand, in step S3, when the fuel nozzle is not lowered to the fuel position (step S3: No), the process waits until the fuel nozzle is lowered to the fuel position.

  In step S5, it is determined whether or not the refueling operator has selected the regular. If the regular is selected (step S5: Yes), for example, a red backlight is displayed on the display unit 5 (step 5). S6).

  On the other hand, if the refueling operator has not selected the regular in step S5 (step S5: No), it is determined in step S7 whether or not the refueling worker has selected high-octane, and high-octane is selected. If present (step S7: Yes), for example, a yellow backlight is displayed on the display unit 5 (step S8).

  On the other hand, if the refueling worker has not selected high-octane in step S7 (step S7: No), it is determined whether or not the refueling worker has selected light oil in step S9, and light oil has been selected. If present (step S9: Yes), for example, a green backlight is displayed on the display unit 5 (step S10). Thus, by changing the color of the backlight of the display unit 5 for each oil type, it is possible to prevent the oiling operator from making an oil type error. In step S9, when the refueling operator has not selected light oil (step S9: No), the process returns to step S5 and waits until the refueling worker selects the oil type.

  Next, in step S11, the amount of oil supply is counted based on the flow rate pulse from the pulse transmitter, and it is determined whether or not the predetermined amount has been supplied. If the predetermined amount has been supplied (step S11: Yes) ), The amount of oil supply (count) is displayed on the display unit 5 (step S12). On the other hand, when the predetermined amount is not refueled (step S11: No), the process waits until the predetermined amount is refueled.

  In step S13, it is determined whether or not the nozzle lift SW has been pressed. If the nozzle lift SW has been pressed (step S13: Yes), the fuel pump is stopped (step S14). On the other hand, in step S13, when the nozzle raising SW is not pressed (step S13: No), the process waits until the nozzle raising SW is pressed.

  In step S15, it is determined whether or not the fueling nozzle has been raised to the standby position. If the fueling nozzle has been raised to the standby position (step S15: Yes), the raising of the fueling nozzle is stopped (step S16). End the operation. On the other hand, in step S15, when the fueling nozzle has not risen to the standby position (step S15: No), it waits until the fueling nozzle rises to the standby position.

  Next, a method for controlling the backlight in the display unit 5 will be described with reference to FIGS.

  In step S21, the illuminance meter attached to the main body 2 determines whether or not the illuminance around the display unit 5 is a predetermined value (for example, 100 lux) or more, and the illuminance around the display unit 5 is equal to or greater than the predetermined value. If so (step S21: Yes), the backlight of the display unit 5 is turned off to display white (step S22). Thereby, external light reflects on a diffusion sheet and it becomes easy to see a number.

On the other hand, if it is determined in step S21 that the illuminance around the display unit 5 is equal to or less than the predetermined value (step S21: No), the backlight (preferably blue) of the display unit 5 is turned on (step S23). . As a result, the backlight emits light and the numbers are easy to see.

  Thus, the visibility of the display part 5 of the fueling operator can be improved by switching on / off of the backlight of the display part 5 according to the illuminance around the display part 5.

  Next, error notification control in the display unit 5 will be described with reference to FIGS.

  When the power of the display 1 is turned on, it is determined in step S31 whether or not the fueling nozzle has been removed. When the fueling nozzle is not removed (step S31: No), the backlight of the display unit 5 is caused to emit light in the standby emission color (step S32).

  On the other hand, when the removal of the fueling nozzle is detected in step S31 (step S31: Yes), it is determined in step S33 whether an error has occurred. If an error has occurred, that is, the oil nozzle has not been removed, but it is detected that the oil nozzle has been removed in step S31 (step S33: Yes), the backlight of the display unit 5 is in an error occurrence state. The emission color is emitted (step S34).

  On the other hand, if no error has occurred in step S33 (step S33: No), it is determined in step S35 whether or not the oil supply nozzle is disengaged from the oil type 1, and the oil supply nozzle disengagement is the oil type If it is 1 (step S35: Yes), the backlight of the display unit 5 is caused to emit light with emission color 1 (step S36).

  On the other hand, in step S35, when the oil supply nozzle is not detached from oil type 1 (step S35: No), in step S37, the oil nozzle is detached from oil type n (n = 2, 3,...). And the backlight of the display unit 5 is caused to emit light of the light emission color n of the oil type in which the oil supply nozzle is detached. Thereby, it is possible to confirm at a glance what kind of error has occurred according to the light emission color of the backlight of the display unit 5.
