[0013] [Figure 1] This figure illustrates a fuel supply device 1 according to this embodiment. [Figure 2] This diagram illustrates the configuration of the nozzle holder 22. [Figure 3] This diagram illustrates the configuration of the refueling section 2 of the fuel supply device 1. [Figure 4] An example of a fuel nozzle 24 equipped with a nozzle cover 25 is shown. [Figure 5] This diagram illustrates the nozzle cover 25 during drainage. [Figure 6] This diagram illustrates the front and rear views of the refueling nozzle 24 being stored in the nozzle holder 22. [Figure 7] This is a schematic diagram illustrating section Z as viewed from the direction of arrow A in Figure 6. [Modes for carrying out the invention]

[0014] Embodiments of the present invention will be described below with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples. Figure 1 is a diagram illustrating a fuel supply device 1 according to this embodiment. Figure 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 of money or 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 in this example is 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 includes a fueling unit 2 and a settlement unit 5.

[0015] The fueling unit 2 includes a fuel type display unit 20, a nozzle holder 22, a fueling nozzle 24, a nozzle cover 25, and a fueling hose 26. The fuel type display unit 20 is a display indicating the type of fuel to be supplied. The fuel type display unit 20 in this example is a display indicating the type of petroleum-based liquid fuel, and is a display combining character display and color display. As the character display in the fuel type display unit 20, for example, the character display of "Regular gasoline" or "Regular" indicating regular gasoline, the character display of "Premium gasoline" or "Premium" indicating premium gasoline, the character display of "Diesel oil" indicating diesel 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 premium gasoline, the character display of "Green" indicating diesel oil, and the color display of "Blue" indicating kerosene.

[0016] The nozzle holder 22 is an example of the holding unit according to the invention, and holds the fueling nozzle 24 described later at a position where it becomes a predetermined height. The nozzle holder 22 is installed on the outer wall surface of the fuel supply device 1 and holds one fueling nozzle 24. The nozzle holder 22 in this example is installed corresponding to each of the fueling nozzles 24 for regular gasoline, premium gasoline, and diesel oil. Further, as illustrated in FIG. 2, the nozzle holder 22 includes a protrusion 220 and a guide portion 221. The protruding portion 220 is a protrusion that determines the storage position of the fuel supply nozzle 24 stored in the nozzle holder 22. When the fuel supply nozzle 24 is stored in the nozzle holder 22, it is located between a pair of trigger guards 244 of the fuel supply nozzle 24. The guide portion 221 is provided on the nozzle holder 22 and is a pair of protruding members that protrude from positions on both sides of the trigger guard 244 when the nozzle holder 22 holds the fuel supply nozzle 24. The guide portion 221 is located on both sides of the protruding portion 220 and guides the outside of the trigger guard 244 to the storage position. The guide portion 221 is formed such that the separation distance between the pair of guide portions 221 gradually decreases from the tip to the base end in the direction of inserting the fuel supply nozzle 24 into and removing it from the trigger guard 244. Further, the guide portion 221 is formed in a shape in which the pair of guide portions 221 bend in opposite directions from the base end to the tip.

[0017] The fuel supply nozzle 24 is an example of the supply nozzle according to the invention and is a trigger nozzle that supplies fuel in a liquid or gaseous state. Further, the fuel supply nozzle 24 includes fuel supply nozzles corresponding to each oil type for regular gasoline, high-octane gasoline, and light oil. Each fuel supply 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.

[0018] The nozzle cover 25 is a cover member that is detachably attached to the fuel nozzle 24. The nozzle cover 25 is provided to cover a portion of the fuel nozzle 24 and is a colored, transparent or translucent sheet material. The nozzle cover 25 is colored to correspond to the fuel supplied by the fuel nozzle 24 to which it is installed. In this example, the nozzle cover 25 is colored "red" for a fuel nozzle 24 that supplies regular gasoline, "yellow" for a fuel nozzle 24 that supplies high-octane gasoline, "green" for a fuel nozzle 24 that supplies diesel fuel, and "blue" for a fuel nozzle 24 that supplies kerosene. The nozzle cover 25 is also transparent enough that the fuel nozzle 24 is visible through it. Further details of the nozzle cover 25 will be described later.

[0019] The fuel supply hose 26 is a fuel supply hose that is not corroded by gasoline, kerosene, or diesel fuel. The fuel supply hose 26 supplies fuel, which is sucked up by a pump (not shown) from an underground storage tank (not shown) that stores fuel, to the fuel supply nozzle 24.

[0020] The settlement unit 5 includes an advertising display unit 50, an item display unit 52, an operation unit 54, and a protective member 56. The advertising display section 50 is an area for displaying advertising content, and for example, an advertising material consisting of a laminated paper medium showing advertising content can be attached to it. The item display unit 52 includes a price display unit 520 that displays the price of the fuel to be supplied, a supply quantity display unit 522 that displays the amount of fuel to be supplied, and a unit price display unit 524 that displays the unit price of the fuel to be supplied.

[0021] The operation unit 54 includes a touch panel that receives user input and displays it on the screen, a currency input unit that accepts currency, and a reader unit that reads credit cards and electronic money. The protective member 56 is a transparent or translucent sheet material, such as polycarbonate. The protective member 56 is slidably positioned to overlap with the advertising display section 50, the item display section 52, or the operation section 54. The protective member 56 is slidably positioned in the direction of the rail 560. This prevents water from getting on it due to rain and snow from accumulating on it.

[0022] Figure 3 is a diagram illustrating the configuration of the refueling section 2 of the fuel supply device 1. As illustrated in Figure 3, the refueling nozzle 24 includes a refueling nozzle 24R for supplying regular gasoline, a refueling nozzle 24H for supplying premium gasoline, and a refueling nozzle 24D for supplying diesel fuel. Note that refueling nozzles 24R, 24H, and 24D are substantially identical except for their coloring, and unless there is a need to distinguish them, they are simply referred to as refueling nozzles 24. Each of the parallel nozzle holders 22 holds one of the refueling nozzles 24R, 24H, and 24D, respectively. In this example, the nozzle holder 22 holds refueling nozzle 24R in the central position, and refueling nozzles 24H and 24D on either side of refueling nozzle 24R. The nozzle holder 22 holds the centrally located fuel nozzle 24R at a higher position than the fuel nozzles 24H and 24D located on either side of it in the vertical direction. In other words, the nozzle holder 22 holds the fuel nozzle in the central position in the vertical direction at a relatively higher position than the other three fuel nozzles 24. When the lower part of the nozzle holder 22 is considered as the reference position, the nozzle holder 22 holds the fuel nozzle 24R at position A, and holds the fuel nozzles 24H and 24D at position B.

[0023] The nozzle holder 22 holds one of two adjacent fuel nozzles 24 at a relatively higher position in the vertical direction. In the nozzle holder 22 illustrated in Figure 3, if we consider two adjacent nozzles, for example fuel nozzle 24R and fuel nozzle 24H, the nozzle holder 22 holds fuel nozzle 24R at a higher position than fuel nozzle 24H in the vertical direction. Also, if we consider two adjacent nozzles, for example fuel nozzle 24R and fuel nozzle 24D, the nozzle holder 22 holds fuel nozzle 24R at a higher position than fuel nozzle 24D in the vertical direction. Furthermore, the nozzle holder 22 holds the refueling nozzle 24 at a relatively different position in the vertical direction depending on the type of fuel being supplied. For example, the nozzle holder 22 holds the refueling nozzle 24 that supplies regular gasoline at a higher position in the vertical direction than the refueling nozzle 24 that supplies fuel other than regular gasoline. In this example, the nozzle holder 22 holds the refueling nozzle 24R at a higher position than the refueling nozzles 24H and 24D. In this way, by relatively changing the height at which the three fuel nozzles 24 are held, the user can prevent mistaking fuel nozzle 24R, fuel nozzle 24H, and fuel nozzle 24D.

[0024] Figure 4 is a diagram illustrating the details of the nozzle cover 25. As illustrated in Figure 4, the fuel nozzle 24 is shown with the nozzle cover 25 attached. The nozzle cover 25 includes the nozzle cover body 251, the curved edge portion 252, and the notched portion 253. The nozzle cover body 251 is made of a transparent or translucent sheet material. The nozzle cover body 251 may be colorless or colored. In this example, the nozzle cover body 251 is colored and its color corresponds to the fuel supplied by the refueling nozzle 24. Furthermore, the nozzle cover body 251 includes a hole 251 formed to a size that allows it to be inserted into the nozzle tube 240, and is formed in a cylindrical shape from the hole 251. In this example, when the nozzle tube 240 of the refueling nozzle 24 is inserted into the hole 251 and the nozzle cover 25 is attached to the refueling nozzle 24, the nozzle cover body 251 is formed in a shape where the diameter of the cylinder gradually expands from the hole 251 toward the trigger guard 244, a so-called flare shape. As a result, the nozzle cover body 251 is provided to cover the portion of the refueling nozzle 24 other than the nozzle tube 240.

[0025] The curved edge portion 252 is formed by bending the periphery of the nozzle cover body 251 from the inside outwards. The curved edge portion 252 may be formed by bending the periphery of the nozzle cover body 251 with creases, or it may be formed by curving without creases.

[0026] The notch 253 is a slit made by cutting a part of the nozzle cover body 251 so as to include at least the curved edge portion 252. The notch 253 is provided at the position of the trigger guard 244 when the nozzle cover 25 is attached to the fuel nozzle 24. In this example, the notch 253 is provided in the range from the vicinity of the hole portion 251 to the curved edge portion 252.

[0027] Next, we will explain the effects of the nozzle cover 25. Figure 5 illustrates the nozzle cover 25 during drainage. As illustrated in Figure 5, during rainfall or snowfall, rain or snow adheres to the surface of the cover body 251. The cover body 251 guides the rain or snow adhering to its surface to the curved edge portion 252. The curved edge portion 252 receives the rain or snow that has been guided to the surface of the cover body 251. The curved edge portion 252 then discharges the received rain or snow from the position of the notch portion 253. In this way, the nozzle cover 25 can protect the fuel nozzle 24 from rain or snow, thereby preventing the diaphragm from getting wet or freezing due to water exposure.

[0028] Figure 6 illustrates the refueling nozzle 24 before and after being stored in the nozzle holder 22. Figure 6(A) is a perspective view before storage, and Figure 6(B) is a perspective view after storage. Figure 7 is a schematic diagram illustrating section Z as seen from the direction of arrow A in Figure 6. Figure 6(A) is a perspective view of section Z before placement, and Figure 6(B) is a perspective view of section Z after placement. As illustrated in Figures 6(A) and 6(B), the user stores the fuel nozzle 24 in the nozzle holder 22 after refueling. Specifically, the user stores the nozzle in the nozzle holder 22 with the nozzle tube 240 facing upwards and the trigger guard 244 facing downwards. As illustrated in Figures 7(A) and 7(B), the user stores the fuel nozzle 24 in the nozzle holder 22 by positioning the projection 220 between the trigger guards 244A and 244B of the fuel nozzle 24, and positioning the guide portions 221 on both sides of the trigger guard 244. The user stores the fuel nozzle by bringing the outside of the trigger guard 244 into contact with the guide portions 221 and sliding it in the insertion direction. In this way, when storing the fuel nozzle 24, the guide part 221 guides it to the storage position, thereby preventing it from shifting away from the storage position.

[0029] As described above, the fuel supply device 1 of this embodiment prevents the accidental supply of an inappropriate type of fuel by relatively changing the height at which the refueling nozzle 24 is held. Furthermore, water leakage can be prevented by attaching the nozzle cover 25 to the refueling nozzle 24.

[0030] (modified version) In the above embodiment, the nozzle holder 22 illustrated in Figure 3 was described as holding the central fuel nozzle 24 of the three fuel nozzles 24 at a higher height than the heights at which each of the fuel nozzles 24 on either side is held. However, it is not limited to this, and for example, the height at which the central fuel nozzle 24 is held may be lower than the heights at which each of the fuel nozzles 24 on either side is held. Also, the nozzle holder 22 may hold at a higher height than the height at which the central fuel nozzle 24 of the three fuel nozzles 24 is held, for at least one of the fuel nozzles 24 on either side is held. In other words, the nozzle holder 22 may hold at a higher or lower height than the height at which each of the three fuel nozzles 24 is held. In this way, by relatively changing the height at which the fuel nozzle 24 is held, the user can prevent mistaking fuel nozzles 24R, 24H, and 24D. [Explanation of symbols]
