BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments according to the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples.
FIG. 1 is a diagram illustrating a fuel supply device 1 according to this embodiment.
FIG. 2 is a diagram illustrating the configuration of the nozzle holder 22. As illustrated in FIG. 1, the fuel supply device 1 is a device that measures a predetermined supply amount of gaseous fuel or liquid fuel and supplies the measured supply amount. The fuel supply device 1 measures the supply amount based on, for example, the amount and quantity specified by the user, and supplies the measured supply amount. Further, the fuel supplied by the fuel supply device 1 is gaseous or liquid fuel supplied to a vehicle equipped with a prime mover. Since the fuel supply device 1 of this example uses a petroleum-based liquid fuel for automobiles, it measures the supply amount of the petroleum-based liquid fuel and supplies the measured supply amount. Note that the fuel supply device 1 may supply electric power instead of fuel. The fuel supply device 1 has a refueling section 2 and a checkout section 5 .

Refueling portion 2 includes fuel type display portion 20 , nozzle holder 22 , refueling nozzle 24 , nozzle cover 25 , and refueling hose 26 .
The fuel type display section 20 is a display that indicates the type of fuel to be supplied. The fuel type display section 20 of this example is a display that indicates the type of petroleum-based liquid fuel, and is a display that combines character display and color display. The character display in the fuel type display unit 20 includes, for example, the character display of “regular gasoline” or “regular” indicating regular gasoline, the character display of “high-octane gasoline” or “high-octane” indicating high-octane gasoline, the character display of “light oil” indicating light oil, and the character display of “kerosene” indicating kerosene. Further, as the color display in the fuel type display unit 200, for example, the color display of "red" indicating regular gasoline, the color display of "yellow" indicating high-octane gasoline, the character display of "green" indicating light oil, and the color display of "blue" indicating kerosene.

The nozzle holder 22 is an example of a holding portion according to the invention, and holds a fuel nozzle 24, which will be described later, at a predetermined height. The nozzle holder 22 is installed on the outer wall surface of the fuel supply device 1 and holds one fuel nozzle 24 . The nozzle holders 22 of this example are installed corresponding to the respective refueling nozzles 24 for regular gasoline, high-octane gasoline, and light oil. Further, as illustrated in FIG. 2 , the nozzle holder 22 includes a protrusion 220 and a guide portion 221 .
The protrusion 220 is a protrusion that determines the storage position of the fuel nozzle 24 stored in the nozzle holder 22, and is positioned between the pair of trigger guards 244 of the fuel nozzle 24 when the fuel nozzle 24 is stored in the nozzle holder 22.
The guide part 221 is provided in the nozzle holder 22 and is a pair of protruding members that protrude from positions on both sides of the trigger guard 244 in a state where the nozzle holder 22 holds the fuel nozzle 24 . The guide portions 221 are positioned on both sides of the projection portion 220 and guide the outside of the trigger guard 244 to the retracted position. The guide portions 221 are formed such that the gap between the pair of guide portions 221 gradually narrows from the distal end to the proximal end in the inserting direction of the direction in which the fuel nozzle 24 is attached to and detached from the trigger guard 244 . Also, the guide portions 221 are formed in a shape in which a pair of guide portions 221 are bent in opposite directions from the proximal end to the distal end.

The fuel nozzle 24 is an example of a supply nozzle according to the invention, and is a trigger nozzle that supplies liquid or gaseous fuel. Further, the fuel nozzles 24 include fuel nozzles 24 corresponding to each type of oil such as regular gasoline, high-octane gasoline, and light oil. Each fuel nozzle 24 is colored in a color corresponding to the fuel to be supplied. For example, it is colored "red" for regular gasoline, "yellow" for high-octane gasoline, "green" for light oil, and "blue" for kerosene.

The nozzle cover 25 is a cover member detachably attached to the fuel nozzle 24 . The nozzle cover 25 is a cover member that is provided so as to partially cover the fuel nozzle 24 and that is colored and made of a transparent or translucent sheet material. The nozzle cover 25 has a color corresponding to the fuel supplied by the fuel nozzle 24 to be installed. The nozzle cover 25 of this example is colored "red" for the refueling nozzle 24 that supplies regular gasoline, "yellow" for the refueling nozzle 24 that supplies high-octane gasoline, "green" for the refueling nozzle 24 that supplies light oil, and "blue" for the refueling nozzle 24 that supplies kerosene. Further, the nozzle cover 25 is so transparent that the fuel nozzle 24 can be seen through it. Details of the nozzle cover 25 will be described later.

The refueling hose 26 is a hose for feeding oil that is not corroded by gasoline, kerosene, light oil, or the like. The fuel hose 26 supplies the fuel nozzle 24 with fuel sucked by a pump (not shown) from an underground storage tank (not shown) that stores fuel.

The checkout unit 5 includes an advertisement display unit 50 , an item display unit 52 , an operation unit 54 and a protection member 56 .
The advertisement display unit 50 is an area for displaying advertisement contents, and for example, an advertisement material laminated with a paper medium showing the advertisement contents can be pasted.
The item display section 52 includes an amount display section 520 that displays the amount of fuel to be supplied, a supply amount display section 522 that displays the amount of fuel to be supplied, and a unit price display section 524 that displays the unit price of the fuel to be supplied.

The operation unit 54 includes a touch panel that receives and displays user operations, a currency input unit that receives currency, and a reading unit that reads credit cards and electronic money.
The protective member 56 is a transparent or translucent sheet material, such as a polycarbonate sheet material. The protective member 56 is slidably arranged at a position overlapping the advertisement display portion 50 , the item display portion 52 , or the operation portion 54 . The protective member 56 is arranged by a rail 560 so as to be slidable in the rail direction. This prevents water wetting due to rain and adhesion of snow.

FIG. 3 is a diagram illustrating the configuration of the fuel supply unit 2 of the fuel supply device 1. As shown in FIG.
As illustrated in FIG. 3, the fuel nozzles 24 include a fuel nozzle 24R that supplies regular gasoline, a fuel nozzle 24H that supplies high-octane gasoline, and a fuel nozzle 24D that supplies light oil. The fuel nozzle 24R, the fuel nozzle 24H, and the fuel nozzle 24D have substantially the same configuration except for coloring, and are simply referred to as the fuel nozzle 24 when there is no particular need to distinguish them. Each nozzle holder 22 arranged in parallel holds a fuel nozzle 24R, a fuel nozzle 24H, and a fuel nozzle 24D. Of the three fuel nozzles 24, the nozzle holder 22 of this example holds the fuel nozzle 24R at the center position, and the fuel nozzles 24H and 24D at both sides of the fuel nozzle 24R. The nozzle holder 22 holds the fuel nozzle 24R located in the center at a higher position in the vertical direction than the fuel nozzles 24H located on both sides of the fuel nozzle 24R and the fuel nozzle 24D. That is, the nozzle holder 22 holds the fuel nozzle located at the center position in the vertical direction at a relatively high position among the three fuel nozzles 24 . The nozzle holder 22 holds the fuel nozzle 24R at the position of the line A, and the fuel nozzle 24H and the fuel nozzle 24D at the position of the line B when the lower part of the nozzle holder 22 is taken as a reference position.

The nozzle holder 22 holds one of the two adjacent fuel nozzles 24 at a relatively high position in the vertical direction. Of the two adjacent nozzles, the nozzle holder 22 illustrated in FIG. 3 holds the fuel nozzle 24R and the fuel nozzle 24H at a position higher than the fuel nozzle 24H in the vertical direction. Further, when focusing on, for example, the fuel nozzle 24R and the fuel nozzle 24D among the two adjacent nozzles, the nozzle holder 22 holds the fuel nozzle 24R at a higher position than the fuel nozzle 24D in the vertical direction.
In addition, the nozzle holder 22 holds the refueling nozzle 24 at different positions in the vertical direction, depending on the type of fuel to be supplied. For example, in the vertical direction, the nozzle holder 22 holds the fuel nozzle 24 that supplies regular gasoline at a position higher than the fuel nozzle 24 that supplies gasoline other than regular gasoline. The nozzle holder 22 of this example holds the fuel nozzle 24R at a higher position than the fuel nozzles 24H and 24D.
In this way, by relatively changing the heights at which the three fuel nozzles 24 are held, the user can prevent the fuel nozzle 24R, the fuel nozzle 24H, and the fuel nozzle 24D from being mistakenly taken.

FIG. 4 is a diagram illustrating the details of the nozzle cover 25. As shown in FIG.
As illustrated in FIG. 4, the fuel nozzle 24 is in a state where the nozzle cover 25 is attached. The nozzle cover 25 includes a nozzle cover main body 251 , a curved edge portion 252 and a notch portion 253 .
The nozzle cover main body 251 is a transparent or translucent sheet material. The nozzle cover main body 251 may be colorless or colored. The nozzle cover main body 251 of this example is colored, and has a color corresponding to the fuel supplied by the fuel nozzle 24 .
Further, the nozzle cover main body 251 includes a hole 251 formed to have a size that allows the nozzle tube 240 to be inserted therethrough, and is formed into a tubular shape from the hole 251 . The nozzle cover body 251 of this example is formed in a so-called flare shape, in which the cylinder diameter gradually expands from the hole 251 in the direction from the nozzle pipe 240 to the trigger guard 244 in a state where the nozzle pipe 240 of the fuel nozzle 24 is inserted into the hole 251 and the nozzle cover 25 is attached to the fuel nozzle 24. Thereby, the nozzle cover main body 251 is provided so as to cover the portion of the fuel nozzle 24 other than the nozzle pipe 240 .

The curved edge portion 252 is formed by bending the peripheral edge of the nozzle cover body 251 from the inside to the outside of the nozzle cover body 251 . The curved edge portion 252 may be bent with a crease around the periphery of the nozzle cover body 251 or may be curved without crease.

The cut portion 253 is a slit formed by cutting a portion of the nozzle cover main body 251 so as to include at least the curved edge portion 252 . The notch 253 is provided at a position where the trigger guard 244 is located when the nozzle cover 25 is attached to the fuel nozzle 24 . The cut portion 253 of this example is provided in a range from the vicinity of the hole portion 251 to the curved edge portion 252 .

Next, the effects of the nozzle cover 25 will be described.
FIG. 5 is a diagram illustrating the nozzle cover 25 during drainage.
As illustrated in FIG. 5, rain or snow adheres to the surface of the cover main body 251 when it rains or snows. The cover main body 251 guides rain or snow adhering to the surface to the curved edge portion 252 . The curved edge portion 252 receives rain or snow guided down on the surface of the cover body 251 . The curved edge portion 252 discharges the rain or snow received from the position where the cut portion 253 is located. In this way, the nozzle cover 25 can protect the fuel nozzle 24 from rain or snow, so that the diaphragm can be prevented from getting wet or freezing due to getting wet.

6A and 6B are diagrams illustrating before and after storing the fuel nozzle 24 in the nozzle holder 22. FIG. FIG. 6A is a perspective view before storage, and FIG. 6B is a perspective view after storage.
FIG. 7 is a schematic diagram illustrating the Z section from the A arrow view in FIG. FIG. 6A is a perspective view of the Z section before placement, and FIG. 6B is a perspective view of the Z section after placement.
As illustrated in FIGS. 6A and 6B, the user stores the fuel nozzle 24 in the nozzle holder 22 after fueling. Specifically, the user stores the nozzle tube 240 in the nozzle holder 22 with the nozzle tube 240 facing upward and the trigger guard 244 facing downward.
As illustrated in FIGS. 7A and 7B, the user positions the projection 220 between the trigger guards 244A and 244B of the fuel nozzle 24, and the guides 221 on both sides of the trigger guard 244, and stores the fuel nozzle 24 in the nozzle holder 22. The user contacts the outside of the trigger guard 244 with the guide part 221 and stores it while sliding it in the inserting direction.
In this way, when the fuel nozzle 24 is retracted, it can be prevented from being displaced from the retracted position by being guided to the retracted position by the guide portion 221 .

As described above, according to the fuel supply device 1 of the present embodiment, by relatively changing the height at which the fuel nozzle 24 is held, it is possible to prevent erroneous supply of an inappropriate type of fuel. Moreover, water leakage can be prevented by attaching a nozzle cover 25 to the fuel nozzle 24 .

(Modification)
In the above-described embodiment, the nozzle holder 22 illustrated in FIG. 3 holds the fuel nozzle 24 at the central position among the three fuel nozzles 24 at a position higher than the height at which the fuel nozzles 24 at the two sides are held. However, the present invention is not limited to this. In addition, the nozzle holder 22 may hold at least one of the fuel nozzles 24 positioned on both sides higher than the center fuel nozzle 24 among the three fuel nozzles 24. That is, the nozzle holder 22 may hold at least one of the three fuel nozzles 24 at a height higher or lower than the height at which the other fuel nozzles 24 are held.
By relatively changing the height at which the fuel nozzle 24 is held in this way, the user can prevent the user from picking up the fuel nozzle 24R, the fuel nozzle 24H, and the fuel nozzle 24D by mistake.
