[overall structure]
FIG. 1 is a schematic exploded perspective view of a vehicle display device (hereinafter referred to as a display device 100). The display device 100 will be described with reference to FIG.

  The display device 100 includes a display panel 200 and analog meters 300 and 500. The display panel 200 includes a display surface 210. The display panel 200 displays an image on the display surface 210. The display panel 200 may be a liquid crystal display that drives liquid crystal and displays an image. Alternatively, the display panel 200 may be a plasma display using plasma emission. Further alternatively, the display panel 200 may be an organic EL display using an organic EL (electroluminescence) element. The principle of this embodiment is not limited to a specific type of display panel 200.

  The image may include information regarding a vehicle on which the display device 100 is mounted. As the information regarding the vehicle, for example, at least one of vehicle state information indicating the state of the vehicle, traveling information regarding the traveling state of the vehicle, and environmental information regarding the environment in which the vehicle travels can be employed. As the state information, for example, information indicating the remaining amount of fuel, the water temperature of the radiator, the lighting state of the headlight, and the like can be adopted. As the travel information, for example, the travel speed of the vehicle, the engine speed, and the like can be adopted. As the environmental information, for example, legal speed determined for the road on which the vehicle is traveling, information on the outside temperature and weather can be adopted.

  Analog meters 300 and 500 are similar to analog meters mounted on known vehicles, and are related to information about the vehicle on which display device 100 is mounted (for example, vehicle speed, engine speed, radiator water temperature, and remaining fuel level). ) May be provided to the driver.

  The analog meter 300 is disposed on the left side of the display panel 200 and includes a C-shaped ring 310 and an indicator hand 320.

  The indicator needle 320 rotates within a region surrounded by the C-shaped ring 310. In the region surrounded by the C-shaped ring 310, an index (for example, a scale line or a number) representing a physical quantity related to the running state of the vehicle on which the display device 100 is mounted is displayed. The presentation of the indicator may depend on various techniques used for analog meters mounted on known vehicles.

  Analog meter 500 is arranged on the right side of display panel 200, and similarly to analog meter 300, information indicating the running state of the vehicle on which display device 100 is mounted (for example, the speed of the vehicle, the engine speed, the water temperature of the radiator). And the remaining amount of fuel), which is different from the analog meter 300, is given to the driver.

  Analog meter 500 includes a C-shaped ring 510 and indicator hands 520 and 530.

  The indicator needles 520 and 530 rotate in the area surrounded by the C-shaped ring 510, respectively. In the region surrounded by the C-shaped ring 510, the display plate 400 may be drawn with an index (for example, a scale line or a number) representing a physical quantity related to the running state of the vehicle on which the display device 100 is mounted.

  The display device 100 further includes a display plate 400. The display board 400 is disposed between the display panel 200 and the analog meters 300 and 500. The display panel 400 includes a flat first surface 411 and a flat second surface 412. The first surface 411 faces the display panel 200. The analog meters 300 and 500 are attached to the second surface 412 opposite to the first surface 411.

  The display panel 400 is provided with a display area 421 that substantially matches the display surface 210 of the display panel 200 in size and shape, and a surrounding area 422 that is an area outside the display area 421.

  For example, the display area 421 may have a higher optical transmittance than the surrounding area 422. Video light emitted from the display surface 210 of the display panel 200 propagates from the first surface 411 to the second surface 412. Thereafter, the image light is emitted from the display area 421 of the second surface 412.

  The display device 100 further includes a ring body 600. The ring body 600 includes a ring member 610 and a translucent ring 620. The translucent ring 620 is disposed in the ring member 610. Since the display panel 200 displays a meter image in the ring body 600, the translucent ring 620 overlaps the meter image. The driver can see the meter image through the translucent ring 620. The translucent ring 620 cooperates with the ring member 610 to contribute to providing a three-dimensional visual impression to the driver.

  The display device 100 further includes a drive unit 700, a meter vessel 810, and a protective plate 820. The indicator hand 320 of the analog meter 300 and the indicator hands 520 and 530 of the analog meter 500 are mechanically connected to the drive unit 700 through the display board 400.

  The drive unit 700 rotates the indicator hands 320, 520, and 530. For the connection between the drive unit 700 and the indicator hands 320, 520, and 530, various techniques used in known vehicles may be used. Therefore, the principle of the present embodiment is not limited to a specific connection technique between the drive unit 700 and the indicator needles 320, 520, and 530.

  The drive unit 700 may include a display control unit 730 (FIG. 4 described later) that generates an image signal for driving the display panel 200. The image signal is output from the drive unit 700 to the display panel 200. The display panel 200 may display a meter image according to the image signal.

  The drive unit 700 may include drive motors 721, 722, and 723 (FIG. 4 to be described later) that drive the indicator hands 320, 520, and 530. The driving unit 700 can include various electric circuits, driving devices, and optical devices for operating the display device 100. The principle of this embodiment is not limited to a specific structure of the drive unit 700.

  The meter vessel 810 is a cylinder that defines a space in which the display panel 200, the ring body 600, the analog meter 300, the analog meter 500, the display board 400, and the drive unit 700 are accommodated. The protection plate 820 closes the opening of the meter vessel 810. The display panel 200, the ring body 600, the analog meters 300 and 500, and the display plate 400 are disposed between the drive unit 700 and the protection plate 820 in the meter vessel 810.

  The protection plate 820 is transparent as a whole. Accordingly, the image light generated by the display panel 200 can reach the protection plate 820 through the display plate 400 and then can enter the eyes of the driver. The protective plate 820 may be subjected to an optical process for suppressing reflection. In this case, the driver can satisfactorily visually recognize the image displayed on the display panel 200 without being hindered by the reflection on the protective plate 820.

  FIG. 2 is a schematic side view of the display device 100.

  As shown in FIG. 2, the display panel 200 may be in close contact with the first surface 411. Alternatively, a slight gap may be formed between the display panel 200 and the first surface 411. Since the display panel 200 is very close to the first surface 411, the driver displays that the image displayed on the display panel 200 is displayed in the display area 421 of the second surface 412 from which the video light is emitted. It becomes easier to perceive.

  Since the driver visually recognizes that the analog meters 300 and 500 are attached to the second surface 412 on which the image is displayed, the display device 100 is visually connected between the analog meters 300 and 500 and the display panel 200. Integrity can be maintained.

The C-shaped ring 310 and the C-shaped ring 510 have the same size and shape, and are arranged at an equal distance in the horizontal direction from the center of the ring member 610. The C-shaped ring 310 is disposed such that the upper end 311 and the lower end 312 face the ring member 610 side, and the C-shaped ring 510 is also disposed such that the upper end 511 and the lower end 512 face the ring member 610 side. Thereby, the analog meter 300 and the analog meter 500 are arranged symmetrically with respect to the ring member 610.

  In the analog meter 300, an indicator portion 313 is disposed along the inner periphery of the C-shaped ring 310. The indicator unit 313 includes a plurality of scale lines arranged radially along the inner periphery of the C-shaped ring 310 and numerical values corresponding to the scale lines. In FIG. 3, a tachometer indicating the engine speed is used as the analog meter 300. Therefore, the index unit 313 displays “0” to “9” indicating the engine speed from 0000 rpm to 9000 rpm in increments of 1000 rpm. Numerical values and ten scale lines corresponding to the numerical values are arranged at equal intervals over almost the entire inner circumference of the C-shaped ring 310. In the example of FIG. 3, the minimum scale line corresponding to the numerical value “0” is arranged on the lower end 312 side, and the highest scale line corresponding to the numerical value “9” is arranged on the upper end 311 side.

  The indicator needle 320 is composed of a needle-like member that has the center of the analog meter 300 as the center of rotation and extends linearly in the radial direction of the C-shaped ring 310. The indicator needle 320 is rotated within a range from a scale line having a numerical value “0” to a scale line having a numerical value “9”.

  The analog meter 500 is composed of two meters arranged above and below sharing the C-shaped ring 510. In the example of FIG. 3, a water temperature gauge is adopted as the upper meter, and a fuel gauge is adopted as the lower meter.

  In the analog meter 500, a fuel gauge indicator 513 a and a water temperature indicator 513 b are arranged along the inner periphery of the C-shaped ring 510. The indicator portion 513a includes a plurality of scale lines arranged radially at equal intervals along the inner periphery of the lower half of the C-shaped ring 510. The indicator portion 513b includes a plurality of scale lines arranged at equal intervals along the inner circumference of the upper half of the C-shaped ring 510. The indicator portion 513b has a scale line indicating the lowest temperature disposed slightly above the middle of the C-shaped ring 510 in the vertical direction, and a scale line indicating the highest temperature is disposed on the upper end 511 side. The indicator portion 513a has a scale line indicating that the fuel is full at a position slightly below the middle of the C-shaped ring 510 in the vertical direction, and a scale line indicating that the fuel is empty has a lower end 512. Arranged on the side.

  In the analog meter 500, an indicator IN indicating that the upper meter is a water temperature meter is disposed on the right side of the indicator needle 530, and an indicator IN indicating that the lower meter is a fuel meter on the right side of the indicator needle 520. Is arranged.

  The indicator needle 520 is configured by a needle-like member extending linearly in the radial direction of the C-shaped ring 510 with the rotation side being slightly below the center of the analog meter 300. The indicator needle 520 is rotated within a range of a scale line indicating that the fuel is full from a scale line indicating that the fuel is empty.

  The indicator needle 530 is formed of a needle-like member that extends linearly in the radial direction of the C-shaped ring 510, with the slightly upper side of the center of the analog meter 300 as the rotation center. The indicator needle 530 is rotated within a range from the scale line indicating the minimum temperature to the scale line indicating the maximum temperature.

  The C-shaped ring 310 has a semicircular arc shape or more that wraps around the lower left corner portion C1 of the display surface 210, and the upper end 311 enters the display surface 210 from the left edge H2 of the display surface 210, thereby entering the left edge H2.

As a result, the indicator hand 530 can rotate on the display panel 400.

  The conversion from the detection signal to the drive signal may depend on various signal processing techniques used in known analog meters. Therefore, the principle of this embodiment is not limited to a specific signal processing technique for converting a detection signal into a drive signal.

  The display control unit 730 receives a detection signal that represents a physical quantity (in this embodiment, the traveling speed of the vehicle) corresponding to the meter image SCI (FIG. 3) displayed on the display panel 200. The display control unit 730 generates an image signal according to the detection signal. The image signal is output from the display control unit 730 to the display panel 200. The display panel 200 displays the meter image SCI on the display surface 210 according to the image signal.

  The signal processing technology from detection signal to image display may depend on various known image generation technologies. Therefore, the principle of this embodiment is not limited to a specific signal processing technique for displaying an image.

  The vehicle further includes a transmission 751, a select lever 752, and a drive selection switch 753. The transmission 751 is a known device configured so that the gear ratio can be shifted to a plurality of stages. The select lever 752 is a known operation unit that, when operated by the driver, shifts the vehicle to the parking (P), reverse (R), neutral (N), and drive (D) ranges.

  The drive selection switch 753 is a switch that is operated by the driver to switch the vehicle travel mode between the normal mode and the sport mode. In the normal mode, ECU 750 automatically shifts the gear position of transmission 751. In the sport mode, the ECU 750 shifts the gear position of the transmission 751 in accordance with a shift operation performed on the select lever 752 by the driver.

  The select lever 752 and the drive selection switch 753 may be levers, buttons, or dials provided near the driver's seat. The principle of this embodiment is not limited to the specific structure of the select lever 752 and the drive selection switch 753.

  The lighting control unit 740 turns on or off the indicator IN according to the detection signal output from the sensor group SSG.

The indicator IN is turned on.

  The display control unit 730 displays the index image 211 and the indicator needle image 212 of the meter image SCI in red in the sport mode. Further, the display control unit 730 displays the index image 211 and the pointing hand image 212 of the meter image SCI with lower saturation than in the sport mode in the normal mode. Therefore, in the sport mode, compared to the normal mode, a person who is riding on the index image 211 displayed in red and the symbol indicating the gear position and the index image 211 displayed with higher saturation. Can draw attention. The red color may be in a range of 5R to 10R or a wider range of 5RP to 5YR, for example, in a hue ring in the Munsell system.

[Display of symbol indicating gear position]
Furthermore, the display control unit 730 displays a symbol indicating the current gear position at a display position slightly below the center in the area of the meter image SCI in the sport mode. When the shift stage of the transmission 751 is shifted in response to a shift operation performed by the driver on the select lever 752, the display control unit 730 displays a symbol indicating the current shift stage being displayed as the next shift stage. Switch to symbol. Hereinafter, the display mode of switching of the symbol indicating the gear position will be described in detail. The driving mode of the vehicle is switched to the sport mode by operating the drive selection switch 753 by the driver.

  FIG. 5 is a diagram schematically showing the relationship between the shift operation of the select lever 752 and the switching of the symbol indicating the gear position. The section (A) of FIG. 5 schematically shows the concept of switching symbols indicating gear positions. Section (B) of FIG. 5 schematically shows the shift operation of the select lever 752.

  In section (B) of FIG. 5, the driver operates the select lever 752 to the right from the D range to set the “M” position. In this state, when the driver performs a shift-up operation by pulling the select lever 752 to the “+” side, the ECU 750 shifts up the shift stage of the transmission 751 by one stage. On the other hand, when the driver performs a downshift operation that pushes the select lever 752 to the “−” side with the select lever 752 set to the “M” position, the ECU 750 shifts the gear position of the transmission 751 by one step. To go down.

  In section (A) of FIG. 5, a symbol indicating the gear position of the transmission 751 is prepared in advance. In the present embodiment, the transmission 751 is configured to be capable of shifting from a first gear ratio to a fifth gear ratio. Accordingly, a symbol indicating the first stage (M1 in the present embodiment) 761, a symbol indicating the second stage (M2 in the present embodiment) 762, a symbol indicating the third stage (M3 in the present embodiment) 763, a symbol indicating the fourth stage (M3 in the present embodiment) In this embodiment, five types of symbols M4) 764 and symbols indicating five stages (in this embodiment, M5) 765 are prepared. Further, the symbols indicating the shift speed are conceptually arranged sequentially from the front side to the back side from the symbol 761 indicating the first gear to the symbol 765 indicating the fifth gear.

  It is assumed that the current gear position of the transmission 751 is three. In this case, the display control unit 730 displays a symbol 763 indicating three levels on the display device 100 as shown in the section (A) of FIG.

  When the driver pulls the select lever 752 to the “+” side and performs a shift-up operation in a state where the symbol 763 indicating the third row is displayed on the display panel 200 in this way, the display control unit 730 displays the display panel 200. The symbol 763 indicating the current gear position displayed on is faded out while moving forward from the display position toward the front side, and the symbol 764 indicating the next gear position is moved forward from the back side toward the display position. While fading in.

  On the other hand, when the driver presses the select lever 752 to the “−” side and performs a downshift operation in a state where the symbol 763 indicating the third level is displayed on the display panel 200, the display control unit 730 displays on the display panel 200. The symbol 763 indicating the current gear position is faded out while moving backward from the display position toward the back side, and the symbol 762 indicating the next gear speed is faded out while moving backward from the front side toward the display position. In. Hereinafter, a specific display mode of switching of a symbol indicating a gear position will be described with reference to the drawings.

  FIG. 6 is a diagram schematically showing a state in which a symbol indicating the current gear position is displayed on the display device 100. FIG. 7 is a diagram schematically illustrating a display state of the display device 100 immediately after the driver performs a shift-up operation. FIG. 8 is a diagram schematically showing a display state of the display device 100 after time from FIG. FIG. 9 is a diagram schematically showing a display state of display device 100 when the switching of the display of the symbol indicating the gear position is completed. With reference to FIG. 6 to FIG. 9, an aspect of switching the display of the symbol indicating the gear position when the driver performs the upshifting operation will be described.

  As shown in FIG. 6, the display control unit 730 displays a symbol 763 (an example of a first symbol) indicating the current gear position in a predetermined size at a display position 770 slightly below the center of the meter image SCI. Here, it is assumed that the current gear position of the transmission 751 is three.

  In this way, with the symbol 763 indicating the current gear position displayed on the display device 100 (display panel 200), the driver pulls the select lever 752 from the “M” position to the “+” side to perform the upshifting operation. When this is done, display control unit 730 first displays a symbol indicating the next gear position above symbol 763 indicating the current gear speed. Since the current gear stage is three, the display control unit 730 displays a symbol 764 (the first gear) as a symbol indicating the next gear stage above the symbol 763 indicating the current gear stage, as shown in FIG. An example of 2 symbols) is displayed. The display control unit 730 displays the symbol 764 indicating the next gear stage with a smaller size and higher transparency than the symbol 763 indicating the current gear stage.

  Next, as shown in FIG. 8, the display control unit 730 gradually enlarges the sizes of the symbols 764 and 763 while moving the symbols 764 and 763 downward at substantially the same speed, and transmits the transparency of the symbol 763. Is gradually increased and the transparency of symbol 764 is gradually decreased. After that, as shown in FIG. 9, the display control unit 730 displays the symbol 764 in a predetermined size as a symbol indicating the current gear position at the display position 770, while deleting the symbol 763.

  When the driver further performs a shift-up operation on the select lever 752, the display control unit 730 similarly changes the symbol indicating the current gear position from the symbol 764 indicating the fourth gear to the symbol indicating the fifth gear. Switch to 765.

  Thus, in this embodiment, when the driver performs a shift-up operation, the display control unit 730 gradually increases the size of the symbol 763 while moving the symbol 763 indicating the current gear position downward, Further, the transmittance of the symbol 763 is gradually increased. Accordingly, the display control unit 730 displays the symbol 763 indicating the current gear stage in a pseudo three-dimensional manner so that the symbol 763 moves forward toward the front, and fades out the symbol 763 indicating the current gear stage.

  Further, the display control unit 730 displays a symbol 764 indicating the next shift step above the symbol 763 indicating the current shift step with a size smaller than that of the symbol 763 indicating the current shift step and high transparency. Thereafter, the display control unit 730 gradually increases the size of the symbol 764 and gradually decreases the transparency of the symbol 764 while moving the symbol 764 indicating the next shift speed downward. Accordingly, the display control unit 730 displays the symbol 764 indicating the next gear stage in a pseudo three-dimensional manner so that the symbol 764 moves forward toward the front, and fades in the symbol 764 indicating the next gear stage.

  FIG. 10 is a diagram schematically illustrating a display state of the display device 100 immediately after the driver performs a downshift operation. FIG. 11 is a diagram schematically showing a display state of the display device 100 after time from FIG. FIG. 12 is a diagram schematically showing the display state of the display device when the switching of the display of the symbol indicating the gear position is completed. With reference to FIG. 6 and FIG. 10 to FIG. 12, a mode of switching the display of symbols indicating the gear position when the driver performs the upshifting operation will be described.

  As shown in FIG. 6, in a state where a symbol 763 indicating the current gear position (3rd stage) is displayed on the display device 100, the driver pushes the select lever 752 from the “M” position to the “−” side to shift. When the down operation is performed, the display control unit 730 first displays a symbol indicating the next gear stage below the symbol 763 indicating the current gear stage. Since the current shift speed is 3, as shown in FIG. 10, the display control unit 730 displays a symbol 762 (the first shift symbol) below the symbol 763 indicating the current gear shift as a symbol indicating the next gear shift. An example of 2 symbols) is displayed. The display control unit 730 displays the symbol 762 indicating the next gear stage with a size larger than that of the symbol 763 indicating the current gear stage and high transparency.

  Next, as shown in FIG. 11, the display control unit 730 gradually increases the size of the symbols 762 and 763 while moving the symbols 762 and 763 upward at substantially the same speed, so that the transmittance of the symbol 763 is increased. Is gradually increased and the transparency of symbol 762 is gradually decreased. After that, as shown in FIG. 12, the display control unit 730 displays the symbol 762 in a predetermined size as a symbol indicating the current gear position at the display position 770, while deleting the symbol 763.

  When the driver further performs a downshift operation on the select lever 752, the display control unit 730 similarly changes the symbol indicating the current gear position from the symbol 762 indicating the second gear to the symbol indicating the first gear. Switch to 761.

  Thus, in the present embodiment, when a downshift operation is performed by the driver, the display control unit 730 gradually reduces the size of the symbol 763 while moving the symbol 763 indicating the current gear stage upward, Further, the transmittance of the symbol 763 is gradually increased. Accordingly, the display control unit 730 displays the symbol 763 indicating the current gear stage in a pseudo three-dimensional manner so that the symbol 763 moves backward toward the back side, and fades out the symbol 763 indicating the current gear stage.

  Further, the display control unit 730 displays a symbol 762 indicating the next gear stage below the symbol 763 indicating the current gear stage with a larger size and higher transparency than the symbol 763 indicating the current gear stage. Thereafter, the display control unit 730 gradually reduces the size of the symbol 762 and gradually decreases the transparency of the symbol 762 while moving the symbol 762 indicating the next shift speed upward. Accordingly, the display control unit 730 displays the symbol 762 indicating the next gear stage in a pseudo three-dimensional manner so that the symbol 762 moves backward toward the back side, and fades in the symbol 762 indicating the current gear stage.

  As described above, in this embodiment, the driver pulls up the select lever 752 from the “M” position to the “+” side to perform a shift-up operation. Accordingly, the direction in which the symbol 763 indicating the current gear stage and the symbol 764 indicating the next gear stage are pseudo-forwardly moved forward, and the direction in which the select lever 752 is pulled to the “+” side from the “M” position. Match. For this reason, according to the present embodiment, the movement of the upshift operation performed on the select lever 752 performed by the driver is suitably expressed on the display device 100 (display panel 200) as the movement of the symbols 763 and 764 indicating the shift speed. can do.

  In the present embodiment, the driver pushes the select lever 752 from the “M” position to the “−” side to perform a downshift operation. Accordingly, the direction in which the symbol 763 indicating the current gear stage and the symbol 762 indicating the next gear stage move backward toward the back side and the direction in which the select lever 752 is pushed from the “M” position to the “−” side are the same. I'm doing it. Therefore, according to the present embodiment, the movement of the downshift operation performed on the select lever 752 performed by the driver is suitably expressed on the display device 100 (display panel 200) as the movement of the symbols 763 and 762 indicating the shift speed. can do.

  The driving mode of the vehicle is often set to the sports mode by a driver who enjoys driving the vehicle with sporty driving. However, in Patent Document 1, as described above, even in the sport mode, the displayed number indicating the current shift speed is merely statically switched. On the other hand, according to the present embodiment, the shift operation performed by the driver on the select lever 752 can be more suitably expressed on the display panel 200 as the movement of the symbol indicating the gear position.

  In the present embodiment, the display control unit 730 arranges a display position 770 for displaying a symbol indicating the current gear position in the area of the meter image SCI. Thus, the limited display area of the display panel 200 can be used effectively.

  In the present embodiment, when the driving mode of the vehicle is the normal mode, the display control unit 730 does not display a symbol indicating the current gear position. Thereby, unnecessary display can be prevented from being performed.

[Modification]
(1) In the above embodiment, when the driver pulls the select lever 752 from the “M” position to the “+” side, the ECU 750 shifts up the gear position of the transmission 751 and the driver moves the select lever 752 to “ When pushed from the “M” position to the “−” side, the ECU 750 shifts down the gear position of the transmission 751, but this direction may be reversed.

  That is, when the driver pulls the select lever 752 from the “M” position to the “+” side, the ECU 750 shifts down the gear position of the transmission 751, and the driver moves the select lever 752 from the “M” position to “−”. ”Side, the ECU 750 may shift up the gear position of the transmission 751.

  In short, when the driver pulls the select lever 752 from the “M” position to the “+” side, the display control unit 730 pseudo-moves the symbol indicating the current gear and the symbol indicating the next gear. When the driver pushes the select lever 752 from the “M” position to the “−” side, the display control unit 730 pseudo-reverses the symbol indicating the current gear and the symbol indicating the next gear. Just do it. That is, the direction in which the symbol indicating the current gear position and the symbol indicating the next gear speed move in a pseudo manner, and the driver operates the select lever 752 from the “M” position to the “+” side or the “−” side. It only needs to match the direction.

  (2) In the above embodiment, the display control unit 730 pseudo-three-dimensionally displays the symbols 761 to 765 indicating the gears by adjusting the size and transparency of the symbols 761 to 765 indicating the gears. The above embodiment is not limited to this. The display control unit 730 may display the symbols 761 to 765 indicating the gears in a three-dimensional manner using a three-dimensional image processing technique.

  (3) In FIGS. 6 to 12, the display control unit 730 does not display the indicator hand image 212 of the meter image SCI when the symbol 763 or the like indicating the current gear position is displayed. Not limited. For example, the display control unit 730 may display only the tip portion of the pointing needle image 212 (that is, the portion overlapping the index image 211). Thus, the vehicle traveling speed can be notified to the driver even while the symbol 763 indicating the gear position is displayed.

  (4) In the example of FIG. 3, a speedometer image is adopted as the meter image SCI in the ring body 600, but this is an example, and other images (for example, a tachometer image, a water thermometer image) , An image of a fuel gauge) may be employed.
