In this case, the scales 47 a and 47 b extend over the inclined portion 42 b and the decoration region 44, and extend radially toward the peripheral edge of the meter region 42.

  Of the scales 47 a and 47 b, the first scale 47 a has a length dimension straddling all the extending portions 44 a of the decoration region 44. On the other hand, the second scale 47b is smaller in length than the first scale 47a and does not straddle all the extending portions 44a. In this case, in the second scale 47b, the rear end is disposed at the same position as the rear end of the first scale 47a in the radial direction of the meter region 42, whereas the front end is the first scale 47b. It arrange | positions in the back position rather than the front side edge part of the scale 47a. In the present embodiment, the first scale 47a spans the three extending portions 44a, while the second scale 47b spans the two extending portions 44a. The first scale 47a and the second scale 47b are alternately arranged.

  In the scales 47a and 47b, the width dimension of the scales 47a and 47b is larger as it is closer to the outer peripheral region 45. While the first scale 47a and the second scale 47b have the same width at the back end, the rate of increase in the width dimension is greater for the first scale 47a than for the second scale 47b. It is getting bigger. In this case, in the first graduation 47a, the width dimension of the portion that is lined up with the front end portion of the second graduation 47b in the circumferential direction of the meter region 42 is larger than the width dimension of the front end portion of the second graduation 47b. It has become.

  In the meter area 42 and the decoration area 44, a non-installed portion of the print layer partially exists, and scales 47a and 47b are formed by the non-installed portion. The transmissivities of the scales 47 a and 47 b are larger than the portion with the largest translucency in the decorative region 44 and are almost the same as the transmissivity of the intermediate region 41.

  As shown in FIG. 2, the hands 48 are arranged on the front side of the meter area 42, and the rotation axis of each hand 48 overlaps the center line O passing through the center of the arc of the meter area 42. In the pointer 48, the length dimension from the center line O is larger than the radius of the flat plate portion 42a and smaller than the radius of the outer peripheral end of the inclined portion 42b. In this case, the distal end portion of the pointer 48 is a front position of the inclined portion 42b and passes through the front positions of the scales 47a and 47b. The center line O extends in the depth direction of the vehicle display device 10.

  The vehicle display device 10 includes a circuit board 51 accommodated in the case 12 behind the display board 11. A drive unit 52 for rotating the pointer 48 is attached to the circuit board 51. The drive unit 52 is connected to the pointer 48 by a pointer shaft portion 53, and the pointer shaft portion 53 penetrates both the circuit board 51 and the display board 11.

  The vehicle display device 10 includes a light emitting unit 55 as a light source provided at a position behind the meter region 42 and a light guide plate 56 that emits light from the light emitting unit 55 toward the display plate 11. . The light emitting unit 55 includes a plurality of LEDs having different emission colors as light emitters, and is mounted on the front surface of the circuit board 51. The circuit board 51 has a light emitting circuit capable of causing the light emitting unit 55 to emit light, and the light emitting unit 55 emits light in a predetermined color according to a command signal for the light emitting circuit.

  The light guide plate 56 is formed in a flat plate shape, and is disposed at a position behind the meter area 42 and the decoration area 44. The light guide plate 56 is disposed at the front position on the rear side surface portion 12b of the case 12, and is fixed to the case 12 while being pressed against the front end portion of the rear side surface portion 12b.

  In the light guide plate 56, when the light of the light emitting unit 55 enters from the rear surface of the light guide plate 56, the light travels inside the light guide plate 56, so that the entire front surface of the light guide plate 56 emits light with substantially the same brightness. In this case, almost the entire meter area 42 is uniformly illuminated from behind by the light of the light emitting unit 55. The light guide plate 56 is overlapped on the rear surface of the flat plate portion 42 a, while being separated rearward from the inclined portion 42 b and the decoration region 44. The distance of the light guide plate 56 from the decorating region 44 increases as the portion is closer to the outer peripheral region 45.

  When the light emitting unit 55 emits light, the scales 47a and 47b are displayed by emitting the light forward. In addition, in the inclined portion 42b, the connection region 43, and the decoration region 44, the luminance accompanying the emission of light gradually increases as it approaches the outer peripheral region 45, and this light causes the inclination portion 42b, the connection region 43, and the decoration region to increase. The area 44 is in a state where gradation is given.

  As described above, the light guide plate 56 is spaced downward from the decorating region 44, but the light from the light guide plate 56 reaches the decorating region 44 without its brightness being extremely reduced. ing. For this reason, in the whole decoration area | region 44, the brightness | luminance by the light from the light-guide plate 56 is ensured appropriately. In this case, the manufacturing cost of the light guide plate 56 can be reduced as compared with the configuration in which the light guide plate 56 has a special shape in accordance with the shape of the decoration region 44 or the inclined portion 42b.

  The operational effects of the present embodiment described so far will be described below.

  According to this embodiment, in the display board 11, the decoration area | region 44 is implement | achieved toward the front from the intermediate | middle area | region 41, the meter area | region 42, and the connection area | region 43, and the three-dimensional structure is implement | achieved. Moreover, in the decoration area 44, since a plurality of portions 44a extending in the depth direction of the vehicular display device 10 are arranged, a sense of depth and a sense of perspective greater than the actual extension dimension to the front of the decoration area 44 is provided. It can be brewed. Furthermore, since the presence of the boundary portion B between the adjacent extending portions 44a is emphasized by the step portion 44b, the stereoscopic effect of the decoration region 44 can be made more remarkable. Accordingly, the vehicular display device 10 can have a three-dimensional effect and enhance the appearance.

  According to the present embodiment, since the stepped portion 44b extends from the front end of the extending portion 44a toward the outer peripheral side, it is possible to realize a configuration in which the stepped portion 44b is easily visible from the front. When both the extended portion 44a and the stepped portion 44b are visually recognized by a user such as a driver, the impression is as if the extended portion 44a extends toward the front side more than the actual extended dimension for each stepped portion 44b. Can be given to the user.

  According to this embodiment, since the extension dimension D1 to the front of the extending portion 44a is the same in each of the extending portions 44a, it is possible to make the user surely recognize the presence of all the extending portions 44a. Become. For this reason, it is possible to create a sense of depth and perspective as if the decoration region 44 extends toward the near side beyond the actual extension dimension by the number of the extension portions 44a.

  According to the present embodiment, when the light emitting unit 55 emits light, in the decorative region 44, the brightness due to the light of the light emitting unit 55 increases as it approaches the outer peripheral region 45, so that the extending portion 44a and the stepped portion 44b In addition to the presence, the depth of the decoration area 44 can be emphasized by the gradation of light.

  According to the present embodiment, when the light emitting unit 55 emits light, a gradation by light is given to each of the extending portions 44a, so that each extending portion 44a has a sense of depth due to a change in luminance. be able to.

  According to this embodiment, since the scales 47a and 47b are extended over the plurality of extending portions 44a, an atmosphere in which the scales 47a and 47b are longer than the actual length dimension can be created by these extending portions 44a. In this case, in the decoration region 44, the lengths of the scales 47a and 47b are emphasized by the plurality of step portions 44b, and the depth feeling of the decoration region 44 is emphasized by the scales 47a and 47b. The three-dimensional effect of the decoration region 44 can be made remarkable by both the scale structure and the scale structure.

  According to the present embodiment, since the width dimensions of the scales 47a and 47b are gradually increased toward the outer peripheral area 45, the perspective of the decoration area 44 can be brought about also by the shape of the scales 47a and 47b.

  According to the present embodiment, since the rear end portions of the scales 47a and 47b are arranged in the meter area 42, the user can visually recognize a portion of the scales 47a and 47b arranged in the decoration area 44. Even if it is not possible, the portion arranged in the meter region 42 can be easily visually recognized. Thus, the visibility of the scales 47a and 47b to the user can be enhanced while creating a sense of depth in the decoration region 44 by the scales 47a and 47b.

(Other embodiments)
Although one embodiment of the present invention has been described above, the present invention is not construed as being limited to this embodiment, and can be applied to this embodiment without departing from the scope of the present invention. .

  In the first modification, the extension dimensions of the extending portions 44a are not the same as in the above embodiment, but the extension dimensions may be different. For example, as shown in FIG. 5, it is set as the structure by which the extension dimension was enlarged about the near extension part 44a among several extension parts 44a. In this configuration, the extension dimension D1 of the first-stage extension 44a from the back is the smallest, and the extension dimension D3 of the third-stage extension 44a is the largest. In this case, the extending portion 44a on the near side seems to extend forward from the stepped portion 44b, so that the extending region 44a is used to create a sense of depth that is greater than the actual depth dimension in the decorative region 44. Can do.

  In the second modification, the extending portion 44a does not extend linearly as in the above-described embodiment, but the extending portion 44a may be curved forward or rearward. For example, as shown in FIG. 6, each extending portion 44 a is configured to curve backward. In this configuration, a boundary portion B between adjacent extending portions 44a protrudes forward, and this protruding portion forms a stepped portion 44b. In this case, the transmissivity of adjacent extending portions 44a has the same value at these boundary portions B. In addition, when it is set as the structure which the extension part 44a curved toward the front, the boundary part B of the adjacent extension part 44a protrudes toward back, and this protrusion part forms the level | step-difference part 44b.

  In Modification 3, the transmissivity of the extending portion 44a and the stepped portion 44b is not the same at the boundary portion B of the adjacent steps of the decorative region 44 as in the above embodiment, but is shown in FIG. Thus, in this boundary part B, the transmissivity of the extension part 44a of the front | former stage may be larger than the transmissivity of the level | step-difference part 44b of a back | latter stage. In this configuration, with respect to each extending portion 44a and stepped portion 44b, the brightness of the second stage is greater than that of the first stage, and the brightness of the third stage is greater than that of the second stage. In this case, it can be emphasized that a plurality of extending portions 44a and stepped portions 44b exist by increasing the luminance of the decoration region 44 stepwise toward the front.

  In the modified example 4, contrary to the modified example 3, as shown in FIG. 8, the transmissivity of the extending portion 44 a of the front stage is the same as that of the step part 44 b of the succeeding stage at the boundary portion B of the adjacent stage of the decoration region 44. It may be smaller than the light transmittance. In this configuration, the luminance that gradually increases toward the second stage in the first stage once decreases in the second stage and then increases again toward the third stage. In this case, it can be emphasized that there are a plurality of extending portions 44a and stepped portions 44b by repeatedly increasing the brightness of the decoration region 44 toward the front.

  In the modified example 5, unlike the embodiment described above, the scales 47a and 47b are not provided in a state of being spanned over the plurality of extending portions 44a. For example, as shown in FIG. 9, the scale 47 c is arranged on the inclined portion 42 b so as not to protrude from the decoration region 44. In this configuration, in the radial direction of the meter region 42, the length dimension of the scale 47c is smaller than the width dimension of the inclined portion 42b.

  In the modified example 6, the stepped portion 44b is not formed in the decorative region 44 as in the above embodiment, but a plurality of extending portions 44a are formed due to differences in color, brightness, saturation, transmissivity, luminance, and the like. It may be formed in the decoration area 44. For example, in FIG. 10, a plurality of extending portions 44 a are formed by applying a plurality of color layers having different brightness and saturation to the decoration region 44. In this configuration, the saturation and lightness become brighter as the front extending portion 44a, and the transmissivity increases stepwise as in the third and fourth modifications. Further, the inner peripheral surface 44 c of the decoration region 44 is a smooth surface without steps or irregularities, and no step is formed at the boundary between the meter region 42 and the outer peripheral region 45. In the decoration region 44, the first and second extension portions 44a extend linearly from the back, while the third extension portion 44a is curved forward. Even with such a configuration, it is possible to create a sense of depth in the decoration region 44 by the plurality of extending portions 44a.

  In the modified example 7, the light is not emitted from the decoration region 44 as in the above embodiment, but the light may not be emitted from the decoration region 44. For example, it is set as the structure by which the transmissivity of the decoration area | region 44 was made very low. In this configuration, although gradation due to light from the decoration area 44 cannot be generated, the inner peripheral surface 44c of the decoration area 44 is illuminated by the light from the scales 47a and 47b and the intermediate display unit 33, thereby increasing the brightness. The gradation by the height can be given to the decoration area 44. For this reason, even if the decoration region 44 does not emit light, the presence of the plurality of extending portions 44a can be emphasized by light.

  In the modification 8, the decoration area | region 44 is not formed in the cylinder shape like the said embodiment, You may become the shape open | released upwards, the downward direction, and the side. In short, it is sufficient that the decoration region 44 is a display extension portion extending forward.

  In the modified example 9, the extending dimension of the extending part 44a and the width dimension of the stepped part 44b are not uniform in the circumferential direction of the decorative region 44 as in the above embodiment, but may be nonuniform. . For example, the extending portion 44 a and the stepped portion 44 b are configured such that the extending dimension and the width dimension at the front portion of the meter region 42 are larger than the extending dimension and the width dimension at the front portion of the intermediate display section 33.

  In the modified example 10, the angle with respect to the flat plate portion 42a is not the same for each of the extending portions 44a as in the above embodiment, but this angle may be different for each extending portion 44a. For example, in a portion where the angle between the flat plate portion 42a and the extended portion 44a is an obtuse angle, such as a portion (see FIG. 2) in which the extended portion 44a extends obliquely forward toward the outer peripheral side, a flat plate The angle between the portion 42a and the extending portion 44a is configured such that the first-stage extending portion 44a is the smallest from the back and the third-stage extending portion 44a is the largest. In this configuration, even if all the extending portions 44a have the same extension dimension, the extension portion 44a on the near side can be easily illusioned so that the extension dimension is larger. A sense of depth can be created.

  In the modification 11, the scales 47a and 47b are not spread over the plurality of extending portions 44a and the meter region 42 as in the above embodiment, but the numbers are spread over the plurality of extending portions 44a and the meter region 42. Also good. In any case, indices such as the scales 47a and 47b and numbers are spread over the plurality of extending portions 44a.

  In the modified example 12, the scales 47a and 47b may not have a shape that gradually becomes thicker toward the front as in the above-described embodiment, but may have a shape that gradually becomes thinner toward the front. . You may be made into the shape where thickness does not change toward the front. For example, the first scale 47a has a shape that gradually increases toward the front, and the second scale 47b has a shape that does not change in thickness toward the front.

  In the modified example 13, the inclined portion 42b of the meter region 42 is not curved backward, but may be curved forward or may not be curved.

  In the modification 14, the meter area | region 42 does not need to have the inclination part 42b. For example, the decoration region 44 is configured to extend forward from the flat plate portion 42a instead of the inclined portion 42b. Even in this configuration, the decoration region 44 extends from the meter region 42 toward the front.

  In the modified example 15, the display device may be mounted not on the vehicle as the vehicle display device 10 as in the above embodiment but on an airplane or a ship. In short, the display device may be anything that can be mounted on a moving body.
