(First Embodiment)
As shown in FIG. 1, the vehicle display device 100 according to the first embodiment of the present disclosure is used in a vehicle and is installed on an instrument panel facing a seat on which an occupant who visually recognizes the device 100 sits. The vehicle display device 100 can display vehicle information toward the visual recognition side where the occupant is located. In the instrument panel, the upper surface portion is formed in a gently curved surface shape that is convex upward of the vehicle.

In this embodiment, the directions indicated by up / down, front / rear, and left / right are described with reference to the vehicle on the horizontal plane.

As shown in FIGS. 2 and 3, such a vehicle display device 100 includes a case unit 10, a main circuit board 26, an image display unit 25, a translucent plate 30, a light source unit 50, an information display unit 16, and the like. Has been done.

The case portion 10 has a back side case 11, a visible side case 12, a plate window member 13, and a smoke plate 14. The back side case 11 is formed with a light-shielding property, for example, by using synthetic resin, and covers the main circuit board 26 from the back side opposite to the visual recognition side.

The visual recognition side case 12 arranged on the visual recognition side with respect to the rear side case 11 is formed of, for example, a synthetic resin so as to have a light-shielding property, and includes an image display unit 25, a light source unit 50, a translucent plate 30, an information display unit 16, and the like. The outer frame portion 12a surrounding from the outside is formed, and the partition portion 12b for partitioning the case internal space is formed.

The plate window member 13 is formed of, for example, a synthetic resin so as to have a light-shielding property, and is arranged so as to project toward the visual recognition side from the light-transmitting plate 30 and the information display unit 16. The plate window member 13 has openings on the visual recognition side and the back surface side, and is formed in a cylindrical shape along the outer periphery of the device 100.

The smoke plate 14 is formed of a semipermeable resin such as a colored acrylic resin or a polycarbonate resin into a curved plate shape that closes the entire surface of the viewing side opening of the plate window member 13. As a result, the image display unit 25, the translucent plate 30, and the information display unit 16 are visible to the occupant through the smoke plate 14. The smoke plate 14 of the present embodiment has a light transmittance of about 30% due to smoke-like coloring, but may be set to any value of 30% or more.

The main circuit board 26 is formed in a flat plate shape by, for example, synthetic resin, and is sandwiched between the back side case 11 and the visual recognition side case 12. An electronic circuit for controlling an image display unit 25, an information display unit 16, etc. is mounted on the main circuit board 26, and a light emitting element 53, a stepping motor 23, etc. of the information display unit 16 are mounted and held. There is.

The image display unit 25 is arranged in the central region of the device 100. The image display unit 25 is arranged on the visual recognition side with respect to the main circuit board 26. The image display unit 25 of the present embodiment employs a liquid crystal display using a thin film transistor (TFT). As the image display unit 25, another display such as an organic EL display can be adopted.

Such an image display unit 25 has a contour rectangular and planar display screen 25a for displaying an image on the viewing side, and a rectangular frame portion 25b surrounding the display screen 25a. A translucent plate 30 is arranged on the visual recognition side of the image display unit 25. For example, the light transmitting plate 30 and the frame portion 25b are in contact with each other via the spacer, so that a slight gap is formed between the display screen 25a and the light transmitting plate 30. The light of the image displayed on the display screen 25a in this way passes through the light transmitting plate 30. In this way, the image is visually recognized by the occupant through the translucent plate 30.

The translucent plate 30 is arranged in the center of the device 100 so as to overlap the image display unit 25. The translucent plate 30 is formed translucently with a synthetic resin such as an acrylic resin or a polycarbonate resin, and has a flat plate shape having a front plate surface 31a exposed to the visual recognition side and a back plate surface 31b on the back surface side.

In the present embodiment, the outer contour formed by the plate end portions 32a, 32b, 32c, 32d, 32e of the outer peripheral portion 32 of the translucent plate 30 has a pentagonal shape as shown in FIG. Each plate end portion 32a, 32b, 32c, 32d, 32e has an elongated planar and mirror-like surface having a width corresponding to the plate thickness. Specifically, the plate end portion 32a on the left side of the vehicle and the plate end portion 32b on the right side of the vehicle are extended linearly from the upper side of the vehicle toward the lower side of the vehicle so as to be substantially parallel to each other. , It is aligned with the end face of the frame portion 25b of the image display portion 25. That is, the outer peripheral portion 32 of the translucent plate 30 extends to a position reaching the outside of the display screen 25a. The plate end portion 32c on the lower side of the vehicle extends linearly from the left side of the vehicle to the right side of the vehicle, substantially perpendicular to the plate end portions 32a and 32b.

On the other hand, on the upper side of the vehicle, the translucent plate 30 has a tapered structure that tapers toward the upper side of the vehicle so as to protrude toward the upper side of the vehicle. In the outer peripheral portion 32 having such a tapered structure, a pair of plate end portions 32d and 32e are formed which are connected to each other and have obtuse angles with each other on the inner side of the translucent plate 30. The plate end portions 32d and 32e are linearly extended. The light source unit 50 is provided so as to face the plate end portions 32d and 32e.

As shown in FIGS. 3 and 4, the light source unit 50 provides the light source light to the light transmitting plate 30. Specifically, the light source unit 50 is composed of a holding member 51, a pair of light source substrates 52, a plurality of light emitting elements 53, a pair of optical sheet members 54, and the like, and is a light source unit that can be easily attached to and detached from the case unit 10. Is forming.

The holding member 51 is arranged so as to face the plate end portions 32d and 32e of the translucent plate 30 by, for example, a light-shielding base material made of synthetic resin. The holding member 51 is fastened and held to the visible side case 12 by, for example, a screw 55. The holding member 51 has a pair of elongated plates 51a that are elongated along each other at obtuse angles so as to match the pair of plate end portions 32d and 32e. Each elongated plate 51a has a plurality of through holes 51b penetrating the elongated plate 51a arranged along the extending direction of the opposite plate end portions 32d and 32e.

The pair of light source substrates 52 are held on the opposite side of the light transmitting plate 30 in the corresponding elongated plate 51a. Each light source substrate 52 mounts the same number of light emitting elements 53 as the through holes 51b. A light emitting diode is adopted for each light emitting element 53, and each light emitting element 53 emits light by being connected to a power source through a conduction pattern on the light source substrate 52. The plurality of light emitting elements 53 are provided so as to be able to switch on or off at the same time, and emit light from a light source in the same color as each other. In particular, each light emitting element 53 of the present embodiment is adapted to emit white light source light.

The pair of optical sheet members 54 are held on the translucent plate 30 side in the corresponding elongated plate 51a. Each optical sheet member 54 is translucently colored, for example, blue, and is a color filter that converts the color tone of the light source light emitted by each light emitting element 53.

Further, a space SP1 surrounding the light source portion 50 is formed between the viewing side case 12 and the plate window member 13, and leakage of the light source light to other than the translucent plate 30 is restricted. That is, the visible side case 12 comes into contact with the back plate surface 31b of the translucent plate 30, and the plate window member is placed on the front plate surface 31a of the translucent plate 30 on the opposite side of the light source portion 50 with the groove portion 40 described later interposed therebetween. The space SP1 in which the light source portion 50 is arranged is closed by the contact of the back side opening of 13.

The light source light emitted from each light emitting element 53 is transmitted through the optical sheet member 54 and then introduced into the inside of the plate of the translucent plate 30 via the plate end portions 32d and 32e (see the arrow in FIG. 4). That is, the plate end portions 32d and 32e on the upper side of the vehicle facing the light source portion 50 function as incident portions on which the light source light is incident on the translucent plate 30. The light source light introduced into the inside of the plate of the translucent plate 30 travels inside the plate with the direction from the upper side of the vehicle toward the lower side of the vehicle as the traveling direction PD. The light source light traveling inside the plate includes light traveling in various directions from each light emitting element 53, and the traveling direction PD referred to here is an average of the various directions in consideration of the intensity. Means direction.

In response to the introduction of the light source light into the plate, the translucent plate 30 has a groove portion 40 and a reflection display portion 33. The groove portion 40 is arranged between the plate end portions 32d and 32e on the upper side of the vehicle into which the light source light is introduced and the reflection display portion 33. The groove portion 40 is formed in a groove shape extending substantially parallel to the plate end portions 32d and 32e at regular intervals from the plate end portions 32d and 32e. The groove portion 40 has a bottomed groove shape that is recessed from the front plate surface 31a toward the back plate surface 31b, contrary to the reflection element 35 of the reflection display unit 33 described later.

Therefore, a part of the light source light introduced into the inside of the plate from the plate end portions 32d and 32e reaches the reflection display unit 33 via the groove portion 40. The light source light incident on the groove 40 is subjected to a predetermined degree of diffusion action by the groove 40 to adjust the illumination unevenness caused by the arrangement of the light emitting elements 53 (more specifically, the illumination unevenness). Reduce).

The reflection display unit 33 is arranged at the center of the translucent plate 30. As shown in FIGS. 5 to 7, the reflection display unit 33 is an element formed by being recessed from the back plate surface 31b toward the front plate surface 31a, and is a plurality of finely sized elements having a recess depth of about 5 to 20 μm. It has a reflecting element 35. As shown in FIG. 1, the reflection display unit 33 forms a symbol 34 that can be visually recognized by the occupant macroscopically by appropriately arranging a plurality of reflection elements 35. In particular, in the present embodiment, the symbol 34 is formed by arranging the plurality of reflecting elements 35 two-dimensionally along the back plate surface 31b. Since each reflecting element 35 has a reflecting surface 37 that reflects the light source light introduced into the plate to the visual recognition side, the symbol 34 shines like a surface light source and is displayed.

Specifically, in the present embodiment, the symbol 34 is a decorative symbol that decorates the image display unit 25. By superimposing the reflection display unit 33 of the present embodiment on the display screen 25a on the visual side of the image display unit 25, the symbol 34 and the image can be superimposed and displayed.

As shown in FIGS. 5 to 7, the plurality of reflecting elements 35 include a composite reflecting element 36. In particular, in the present embodiment, all the reflection elements 35 constituting the reflection display unit 33 are composite reflection elements 36.

Each composite reflecting element 36 is formed by being recessed in a triangular pyramid shape from the back plate surface 31b toward the front plate surface 31a. In particular, as shown in FIG. 5, each composite reflecting element 36 has an isosceles right triangle shape on a plan view taken along the plate thickness direction TD of the translucent plate 30 perpendicular to the back plate surface 31b. Each composite reflective element 36 has a composite reflective surface 37 composed of two inclined surfaces 37a and 37b, and an element back surface 38.

The two inclined surfaces 37a and 37b are arranged at positions corresponding to the isosceles right triangles on the plan view. The two inclined surfaces 37a and 37b have outer contours as two surfaces of the triangular pyramid-shaped composite reflecting element 36 facing the plate end portions 32d and 32e (that is, the upper side of the vehicle) into which the light source light is introduced. Each is formed in the shape of a triangular plane.

Each composite reflecting element 36 has a linear connecting side 36b connecting two inclined surfaces 37a and 37b along a cross section that bisects an isosceles triangular apex angle (or base) on a plan view. Have. The connection side 36b is inclined so as to be more distant from the plate end portions 32d and 32e on the upper side of the vehicle into which the light source light is introduced toward the front plate surface 31a side from the back plate surface 31b side. As shown in 6, the inclination angle is, for example, 45 degrees with respect to the plate thickness direction TD. Similar to the connection side 36b, the inclined surfaces 37a and 37b are further separated from the plate end portions 32d and 32e on the upper side of the vehicle into which the light source light is introduced as the light source is directed from the back plate surface 31b side to the front plate surface 31a side. It is tilted to do. The inclined surfaces 37a and 37b also have an inclined angle of, for example, 45 degrees with respect to the plate thickness direction TD on the cross section parallel to the cross section that bisects the apex angle described above.

Further, the two inclined surfaces 37a and 37b are set so that their orientations are different from each other. Specifically, the two inclined surfaces 37a and 37b face each other diagonally sideways along the inclined sides of the isosceles triangle on the plan view. The inclined surface 37a on the left side of the vehicle slightly faces the left side of the vehicle, and the inclined surface 37b on the right side of the vehicle slightly faces the right side of the vehicle. Specifically, in the present embodiment, the triangular pyramid-shaped composite reflecting element 36 includes the concave bottom portion 36a having the deepest recessed depth, and is particularly shown on a vertical cross section perpendicular to the cross section that bisects the apex angle described above. As shown in 7, the two inclined surfaces 37a and 37b are inclined in opposite directions with respect to the back plate surface 31b, for example, at an inclination angle of 10 degrees.

As shown in FIGS. 5 and 6, the element back surface 38 is arranged at a position corresponding to the base in an isosceles triangle shape on the plan view, and is located on the side opposite to the plate end portions 32d and 32e into which the light source light is introduced. That is, it is formed facing the lower side of the vehicle). The back surface 38 of the element has an outer contour formed in a triangular planar shape. The back surface 38 of the element is inclined so as to approach the plate end portions 32d and 32e on the upper side of the vehicle into which the light source light is introduced toward the front plate surface 31a side from the back plate surface 31b side, and is inclined with respect to the plate thickness direction TD. For example, it has an inclination angle of 5 degrees.

In the present embodiment, the composite reflective elements 36 are separated from each other by the arrangement pitches PT1 and PT2 set in the arrangement directions D1 and D2, respectively, via the flat portion 39 formed flat on the back plate surface 31b. They are arranged one by one in isolation. The arrangement direction D2 is along the direction from the upper side of the vehicle to the lower side of the vehicle, which is the main traveling direction PD of the light source light, and the arrangement direction D1 is a direction substantially perpendicular to the arrangement direction D2.

The plurality of composite reflection elements 36 are arranged in a so-called staggered pattern in which the positions of the concave bottom portions 36a are shifted by half the arrangement pitches PT1 and PT2 for each row. Here, the arrangement pitches PT1 and PT2 of the composite reflection element 36 are set to extremely small values with respect to the arrangement pitch of the light emitting element 53 of the light source unit 50.

Due to the light source light passing through the groove portion 40, the reflection display unit 33 causes the symbol 34 to emit light and display in the form of a surface light source with relatively uniform brightness. Further, due to the presence of the light source light that does not pass through the groove portion 40, the reflection display unit 33 superimposes the light source light on the surface light source-like light emission display, and causes the light source image by the plurality of point light source-like light source elements 53 in the design 34. It is possible to imprint and display the composite reflecting element 36 in the area where the compound reflecting elements 36 are arranged.

More specifically, since the composite reflection element 36 reflects the light source light by the composite reflection surface 37 composed of the two inclined surfaces 37a and 37b, it depends on the angle at which the viewer sees the symbol 34 of the reflection display unit 33. , The appearance of the light source image changes.

For example, when the viewer visually recognizes the design 34 so as to look down slightly from the upper side of the vehicle, a plurality of linearly extending light source images are reflected according to the arrangement interval of the light emitting elements 53, and stripes are formed on the design 34 of the reflection display unit 33. Causes uneven brightness. When the viewer visually recognizes the symbol 34 from the front along the plate thickness direction TD of the translucent plate 30, the linearly extending light source image is reflected twice as much as in the above case, and the symbol 34 has a complicated stripe shape. Causes uneven brightness. When the viewer visually recognizes the symbol 34 so as to look up slightly from the lower side of the vehicle, the number of light source images returns to the first case.

If the occupant as a visual observer is, for example, a driver, the symbol 34 is visually recognized as shining due to the movement of the eye position accompanying the driving motion of the vehicle. Since the composite reflection elements 36 are arranged in a staggered pattern, it is possible to give a relatively gentle impression while expressing a glittering feeling in the symbol 34.

On the other hand, when the light source unit 50 is turned off and the light source light is not introduced into the inside of the translucent plate 30, each composite reflecting element 36 has a fine size and is formed via the flat portion 39, so that the symbol 34 is formed. It is almost invisible.

As shown in FIG. 1, the information display unit 16 is arranged next to the translucent plate 30 and the image display unit 25, and more specifically, the information display unit 16 is provided in pairs so as to sandwich the translucent plate 30 and the image display unit 25 on the left and right. ing. Each information display unit 16 has a display plate 17 and a pointer unit 22. The display board 17 is also generally called a dial, and the surface of a translucent base material 18 such as an acrylic resin or a polycarbonate resin is printed or partially printed or painted. It is formed in a flat plate shape. Such a display board 17 covers the opening of the viewing side case 12 from the viewing side so that the main circuit board 26 is not visually recognized from the viewing side.

As shown in FIG. 2, the light from the light emitting element 16a arranged on the main circuit board 26 illuminates the display board 17, and the display lamp and the index (illustration) formed so that the light can be transmitted through the display board 17. Is omitted), and information is displayed.

The pointer unit 22 has a stepping motor 23 and a pointer 24. The stepping motor 23 is held on the back side of the main circuit board 26.

The pointer 24 integrally has a connecting portion 24a and an indicating portion 24b. The connecting portion 24a is arranged through a through hole formed in the display plate 17, and is connected to the rotating shaft of the stepping motor 23. The indicator portion 24b is arranged on the visual recognition side with respect to the display plate 17, and has a needle shape. The pointer 24 rotates according to the output of the stepping motor 23, and indicates an index on the display board 17. In this way, the information display unit 16 displays some vehicle information such as the speed of the vehicle and the engine speed according to the instruction position of the instruction unit 24b.

By the way, as shown in FIGS. 8 and 9, in each information display unit 16, the display plate 17 is arranged slightly on the visual recognition side with respect to the front plate surface 31a of the translucent plate 30. Each display plate 17 is provided so as to extend from the information display unit 16 side to the translucent plate 30 side as it is, so that the display plate 17 overlaps the outer peripheral portions 32 on the right side of the vehicle and the left side of the vehicle. A part of the display plate 17 extended in this way projects from the information display unit 16 toward the translucent plate 30 in an eaves shape so as to cover at least a part of the plate end portions 32a and 32b of the translucent plate 30 from the visual recognition side. , The eaves 19 are formed.

Here, the overlap allowance OL (in other words, creepage distance, see FIG. 10) of the eaves portion 19 with the translucent plate 30 is set to be equal to or less than the width of the frame portion 25b of the image display unit 25, for example, set to 2 to 3 mm. Has been done. Due to the setting of the overlap allowance OL, the eaves portion 19 is located outside the display screen 25a. It is suppressed that the eaves portion 19 obstructs the display screen 25a, and the display of the image on the display screen 25a can be fully utilized.

Further, a gap GP (see FIG. 10) of 0.5 mm or less is provided between the translucent plate 30 and the eaves 19. In this way, the eaves portion 19 has a facing portion 19a facing the front plate surface 31a on the outer peripheral portion 32 of the translucent plate 30.

As shown in FIG. 10, in the eaves portion 19 of the display plate 17, a layer is formed on both sides 18a and 18b of the base material 18 by printing or painting. An anti-glare translucent layer 20 common to other parts of the display plate 17 is formed on the surface 18a on the viewing side of the base material 18 facing the viewing side. The anti-glare translucent layer 20 is composed of, for example, a translucent material containing acrylic resin as a main component and having translucency containing light diffusing particles 20a such as beads. With such an anti-glare translucent layer 20, when external light such as sunlight incident on the device 100 is incident on the display plate 17, the light diffusing particles 20a diffuse the external light. Therefore, the translucent plates 30 and the display plates 17 arranged side by side have different facial expressions for external light, and the appearance of the device 100 can be changed.

A light absorption layer 21 common to most of the other parts of the display plate 17 is formed on the back surface 18b of the base material 18 facing the back surface. The light absorption layer 21 is formed by printing black ink containing, for example, carbon black or the like on the surface 18b.

When the light source light is introduced into the inside of the translucent plate 30 from the light source unit 50, a part thereof reaches the left and right plate end portions 32a and 32b. As a result, the light source light leaks from the plate end portions 32a and 32b. It should be noted that FIGS. 8 and 9 show an example of how the light source light travels with arrows.

Here, if there is no eaves portion 19, the light emitted from the plate end portions 32a and 32b into the space SP2 between the translucent plate 30 and the information display unit 16 will dimly illuminate the information display unit 16. The visibility and appearance of the information display unit 16 deteriorate.

However, in the present embodiment, since the eaves portion 19 covers the space SP2, the space SP2 cannot be visually recognized from the visual recognition side. Further, even if the light source light emitted into the space SP2 tries to leak from the gap GP between the light transmitting plate 30 and the eaves portion 19, the light absorption layer 21 absorbs the light source light at the facing portion 19a, so that the light absorbing layer 21 absorbs the light source light from the gap GP. It is difficult to see the light leakage.

Further, on the outer peripheral portion 32 of the translucent plate 30 on the lower side of the vehicle, the visible side case 12 is in contact with the back plate surface 31b, and the plate window member 13 is in contact with the front plate surface 31a. A space SP3 closed between the viewing side case 12 and the plate window member 13 is configured, and the light source light from the plate end portion 32c on the lower side of the vehicle is emitted to the space SP3, so that light leakage is visible. It's hard to be done.

(Action effect)
The effects of the first embodiment described above will be described again below.

According to the first embodiment, the eaves portion 19 projects from the information display unit 16 toward the translucent plate 30 in an eaves shape, and at least a part of the plate end portions 32a and 32b in the outer peripheral portion 32 of the translucent plate 30 is on the viewing side. It is formed to cover from. Therefore, even in a layout in which the translucent plate 30 and the information display unit 16 are arranged next to each other, the plate end portions 32a and 32b are closed from the visual recognition side at the adjacent portion between the translucent plate 30 and the information display unit 16. Can be easily realized. Therefore, even if light is introduced into the inside of the translucent plate 30 from the light source unit 50 and a part of the light leaks from the plate end portions 32a and 32b, the light leakage can be visually recognized from the visual recognition side. It is regulated by shading at the eaves 19. Therefore, both the display of the light source light reflected by the reflecting element 35 and the display by the information display unit 16 can be conspicuous, and the appearance can be improved.

Further, according to the first embodiment, the eaves portion 19 is formed as a part of the plate-shaped display plate 17 for displaying information in the information display unit 16. By using the display plate 17 for the eaves 19, it becomes difficult for light leakage to wrap around the display plate 17 to the visual recognition side, and the portion exposed to the visual recognition side of the information display unit 16 is suppressed from being illuminated. The light-shielding effect of light leakage to the information display unit 16 is further enhanced, and the appearance can be improved.

Further, according to the first embodiment, in the eaves portion 19, a light absorption layer 21 having light absorption property is formed on at least one of the surface 18a on the viewing side and the surface 18b on the back surface side. Since the light absorption layer 21 absorbs the light leaked from the plate end portions 32a and 32b, the light shielding effect of the eaves portion 19 becomes higher.

Further, according to the first embodiment, the light absorption layer 21 is formed on the surface 18b on the back surface side so as to face the outer peripheral portion 32 of the light transmissive plate 30. Therefore, even if the light leakage from the plate end portions 32a and 32b tries to leak further to the visual recognition side from between the light transmitting plate 30 and the eaves portion 19, the light leakage is efficiently absorbed by the light absorption layer 21. Therefore, the light-shielding effect of the eaves 19 becomes remarkable.

Further, according to the first embodiment, the image display unit 25 is arranged on the back side of the light transmitting plate 30, and displays an image visually recognized through the light transmitting plate 30 on the display screen 25a. In such a configuration, the light leakage is restricted by the light blocking effect of the eaves portion 19, so that the light source light reflected by the reflecting element 35 is displayed and the information display unit 16 displays the light. Not only that, the display of the image on the display screen 25a can be displayed with good appearance at the same time. Therefore, the appearance of the vehicle display device 100 as a whole is also extremely good.

Further, according to the first embodiment, the translucent plate 30 is extended to a position where the outer peripheral portion 32 reaches the outside of the display screen 25a. Therefore, even if the eaves portion 19 overlaps with the outer peripheral portion 32, the configuration in which the eaves portion 19 is located outside the display screen 25a is easily realized. As a result, the eaves portion 19 is prevented from blocking the display of the image by the image display unit 25, so that the appearance of the vehicle display device 100 is extremely good.

(Second Embodiment)
As shown in FIG. 11, the second embodiment is a modification of the first embodiment. The second embodiment will be described focusing on the differences from the first embodiment.

Similar to the first embodiment, the eaves portion 219 of the second embodiment also has a facing portion 219a facing the front plate surface 31a on the outer peripheral portion 32 of the translucent plate 30. However, the facing portion 219a of the second embodiment is provided with a protruding portion 219b that protrudes toward the front plate surface 31a, for example, by press working or the like.

Each protruding portion 219b is provided so as to extend substantially parallel to the corresponding plate end portions 32a and 32b, and protrudes in a rounded curved surface shape so that no gap is formed between the translucent plate 30 and the eaves portion 219. , The space between the translucent plate 30 and the eaves 219 is closed. In this way, the protruding portion 219b functions as a pressure contacting portion that is pressed against the front plate surface 31a on the outer peripheral portion 32 of the translucent plate 30.

According to the second embodiment described above, the eaves portion 219 has a protruding portion 219b that functions as a pressure contact portion that is pressed against the front plate surface 31a. By doing so, for example, a gap is less likely to occur between the front plate surface 31a of the translucent plate 30 and the eaves portion 219 due to vibration of the vehicle, thermal expansion of parts, or the like. It becomes more difficult for the light leakage to further leak to the visual recognition side from between the light transmitting plate 30 and the eaves portion 219.

(Other embodiments)
Although the plurality of embodiments have been described above, the present disclosure is not construed as being limited to those embodiments, and is to be applied to various embodiments and combinations without departing from the gist of the present disclosure. Can be done.

Specifically, as the first modification, the eaves portion 19 may not be formed as a part of the display plate 17. For example, in the information display unit 16, a ring-shaped decorative member is provided so as to surround the pointer 24, and a part of the decorative member projects in an eaves shape toward the translucent plate 30 to form the eaves portion 19. It may have been done.

As the second modification, the image display unit 25 may not be arranged on the back surface side of the translucent plate 30. For example, instead of the image display unit 25, a pointer may be arranged, or a black plate may be arranged so that the display of the symbol 34 stands out.

As the third modification, various configurations can be adopted as the configurations of the layers formed on the surfaces 18a and 18b of the base material 18 of the display plate 17. For example, a white layer having a light-shielding property may be formed on the surfaces 18a and 18b on the back surface side of the base material 18. Further, for example, instead of forming the light-shielding layer on the back surface 18b of the base material 18, a light-shielding layer such as the light absorption layer 21 may be formed on the visual-viewing surface 18a. Further, a semipermeable layer may be formed on each of the surfaces 18a and 18b.

As a modification 4, the display plate 17 does not have to have a layer formed on the surfaces 18a and 18b of the translucent base material 18, for example, the base material 18 itself is made black with a light-shielding property to have a light absorption function. May be added.

As a modification 5, the information display unit 16 may have a display unit for displaying an image together with or in place of the pointer unit 22.

As a modification 6, a light guide portion 60 may be separately provided on the light transmitting plate 30 as an incident portion. In the example of FIG. 12, the light guide portion 60 extending toward the main circuit board 26 on the back side is provided on the outer peripheral portion 32 on the upper side of the vehicle of the translucent plate 30. The light source unit 50 has a plurality of light emitting elements 53 arranged on the main circuit board 26 so as to face the tip portion 60a of the light guide unit 60 in the plate thickness direction TD. The base end 60b of the light guide 60 has a light guide reflecting surface that reflects the light source light incident on the inside of the light guide 60 from the light emitting element 53 via the tip 60a toward the groove 40 and the reflection display 33. 61 is provided. In the example of FIG. 12, the groove portion 40 may be arranged in the light guide portion 60.
