  Here, also in the display device for vehicles provided on the instrument panel, a display device for vehicles that can make the display portion visually recognized by the occupant a far viewpoint and switch the viewing distance is required.

  The present invention has been made to solve the above problems, and provides a display device for a vehicle that can make a display portion that a passenger can visually recognize with a compact structure as a far viewpoint and can switch a viewing distance. The purpose is to provide.

  A display device for a vehicle having a configuration according to claim 1 is a display device for a vehicle that is provided on an instrument panel in a vehicle interior and allows a passenger to visually recognize a display unit from the vehicle interior, and is a longitudinal section along the vehicle longitudinal direction. The reflective surface is disposed in a polygonal shape with an even number of sides when viewed, and one side of the vehicle interior is an opening, and the display light of the display unit reflects the substantially cylindrical reflection. A first optical path that is incident from the opening of the opening and is reflected by the reflecting surface in order around the vehicle width direction axis, and then emits display light from the opening toward the passenger, and the display light of the display Before the light enters from the opening of the substantially cylindrical reflecting portion, the second reflecting path reflected by the reflecting member toward the occupant, and when the reflecting member is moved or rotated, the first optical path And the second optical path are switched.

  In the vehicle display device having the configuration according to claim 1, the display light of the display unit is incident on the first optical path from the opening of the substantially cylindrical reflection unit, and is sequentially reflected by the reflection surface around the vehicle width direction axis. After that, it is an optical path for emitting display light toward the passenger from the opening. Therefore, the optical path length of the first optical path is long, and the virtual image of the display unit visually recognized by the occupant is located on the vehicle front side with respect to the display unit provided on the instrument panel. That is, the display unit (virtual image) visually recognized by the occupant is taken as the far viewpoint. In other words, as compared with the case where the present invention is not applied, a display unit that is visually recognized by an occupant with a compact structure can be a far viewpoint.

  On the other hand, the second optical path is an optical path in which the reflecting member reflects toward the passenger before the display light of the display unit enters from the opening of the substantially cylindrical reflecting unit by moving or rotating the reflecting member. ing. Therefore, the optical path length of the second optical path is shorter than that of the first optical path, and the virtual image of the display unit visually recognized by the occupant is located on the vehicle rear side (vehicle interior side) of the first optical path. That is, the display part (virtual image) visually recognized by the occupant is set as the near viewpoint.

  In this way, compared to the case where the present invention is not applied, the display portion that is observable by the occupant with a compact structure can be set as the far viewpoint, and the viewing distance can be switched.

  Here, since the scenery outside the vehicle viewed from the interior of the vehicle is a far viewpoint, it is considered that the display unit is easier to see from the viewpoint of the viewing distance because the far viewpoint is easier to focus. Therefore, from the viewpoint of the viewing distance, the display unit can be easily viewed by selecting the first optical path which is the far viewpoint.

  However, even if the display device for a vehicle is provided on a near-view instrument panel, if the display unit of the display device for a vehicle is a far viewpoint, some people (occupants) may feel uncomfortable. Further, depending on the display contents (for example, numbers and characters) of the display unit, there is a case where it is desired to view from a near viewpoint. In such a case, the second optical path that is the near viewpoint is switched (selected).

  It should be noted that the number of reflecting surfaces arranged in a polygonal shape having an even number of sides with one side being an opening is an odd number. Therefore, after the display light of the display unit enters the opening of the substantially cylindrical reflection part and is reflected by the reflecting surface in order around the vehicle width direction axis, the display light is directed from the opening toward the passenger. Reflects an odd number of times until emitted. Therefore, the vertical direction of the virtual image of the display unit coincides between the second optical path and the first optical path that are reflected once.

  Moreover, since the reflecting surface forms a polygonal inner surface having an even number of sides, the reflecting surface is a flat surface or a substantially flat surface. Therefore, the virtual image is less distorted than the configuration in which it is reflected by a curved reflecting surface (because it is reflected by a flat or substantially flat reflecting surface, no distortion or almost no distortion occurs). Therefore, the visibility of the virtual image (display unit) is higher than that of the configuration in which the light is reflected by the curved reflecting surface.

  According to a second aspect of the present invention, in the configuration of the first aspect, the reflective member is provided in the opening of the substantially cylindrical reflective portion so as to be rotatable about the vehicle width direction as an axial direction. A double-sided reflection plate having both surfaces as reflection surfaces, and the first optical path is configured such that the display light of the display unit is reflected by one surface of the double-sided reflection plate, and the opening of the substantially cylindrical reflection unit. After being incident and reflected by the reflecting surface in order around the vehicle width direction axis, it is further reflected by the other surface of the double-sided reflector, and the display light of the display unit is emitted toward the passenger from the opening. The second optical path is an optical path that reflects display light toward an occupant on one or the other surface of the double-sided reflection plate, and the double-sided reflection plate is rotated to change the angle. One optical path and the second optical path are switched.

  In the vehicular display device according to the second aspect, a double-sided reflection plate having both surfaces as reflection surfaces is provided at the opening of the substantially cylindrical reflection portion so as to be rotatable about the vehicle width direction.

  In the first optical path, the display light is reflected by one surface of the double-sided reflector, enters from the opening of the substantially cylindrical reflecting portion, and is reflected by the reflecting surface in order around the vehicle width direction axis. Furthermore, the light is reflected by the other surface of the double-sided reflector, and is used as an optical path for emitting display light from the opening toward the passenger.

  On the other hand, the second optical path is an optical path that reflects display light toward the occupant on one or the other surface of the double-sided reflector. And a 1st optical path and a 2nd optical path can be switched in a short time because a double-sided reflecting plate rotates and an angle changes. That is, the viewing distance can be switched in a short time.

  In the first optical path, the display light of the display unit enters from the opening of the substantially cylindrical reflection unit and is reflected by the reflecting surface in order around the vehicle width direction axis, and then the display light is directed from the opening to the passenger. In addition to the odd number of times of reflection, the light is reflected on both surfaces of the double-sided reflector (two times of reflection). Therefore, since the reflection is added twice to the odd number of reflections, the reflection is odd number of times in total. Therefore, the vertical direction of the virtual image of the display unit coincides between the second optical path and the first optical path that are reflected once.

  The vehicle display device according to claim 3 is the configuration according to claim 1, wherein the reflection member is any one of the reflection surfaces constituting the inner surface of the substantially cylindrical reflection portion, and the reflection surface Is rotated or moved so that the first optical path and the second optical path are switched.

  In the vehicle display device according to claim 3, any one of the reflecting surfaces constituting the inner surface of the substantially cylindrical reflecting portion is rotated or moved, so that the display light of the display portion is reflected by the substantially cylindrical reflecting portion. The light is reflected toward the occupant before entering from the opening. That is, since any one of the reflecting surfaces constituting the inner surface of the substantially cylindrical reflecting portion also serves as the reflecting member, the number of parts is reduced accordingly.

  The vehicle display device according to claim 4 is the configuration according to any one of claims 1 to 3, wherein the substantially cylindrical reflection portion is provided with the reflection surface in a substantially rectangular tube shape. And the one side of the vehicle interior side is a substantially U-shaped reflecting portion having the opening.

  In the vehicle display device according to claim 4, the substantially cylindrical reflecting portion is a substantially U-shaped reflecting portion in which a reflecting surface is provided in a substantially rectangular tube shape and one side of the vehicle interior side is an opening. . That is, since the reflecting surface may be disposed in a substantially U shape, the structure of the substantially cylindrical reflecting portion can be simplified.

  As described above, according to the vehicular display device according to the first aspect, the display unit (virtual image) visually recognized by the occupant can be a far viewpoint with a compact structure, and the viewing distance can be switched. It has the excellent effect of being able to.

  According to the vehicle display device of claim 2, it is possible to switch the viewing distance (the first optical path and the second optical path) in a short time by rotating the double-sided reflector and changing the angle. It has the effect.

  According to the vehicle display device according to claim 3, any one of the reflection surfaces constituting the inner surface of the substantially cylindrical reflection portion is before the display light of the display portion enters from the opening of the substantially cylindrical reflection portion. Moreover, since it also serves as a reflecting member that reflects toward the occupant, it has an excellent effect that the number of parts can be reduced.

  According to the vehicle display device of the fourth aspect, there is an excellent effect that the structure of the substantially cylindrical reflecting portion can be simplified.

  First, a combination meter as a vehicle display device according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of an instrument panel provided with a combination meter as viewed from the obliquely rear side of the vehicle. 2 and 3 are longitudinal sectional views schematically showing a longitudinal section of the instrument panel along the line AA shown in FIG. 1 (along the vehicle front-rear direction) (see FIG. 2 and FIG. 3). The difference will be described later). In addition, an arrow UP in the figure indicates a vehicle upward direction, an arrow FR indicates a vehicle front direction, and an arrow OUT indicates a vehicle width direction outer side direction.

  As shown in FIG. 1, the instrument panel 80 provided in the vehicle front side part of the vehicle interior 12 of the vehicle 10 is a long panel whose longitudinal direction is the vehicle width direction. As shown in FIGS. 1 and 2, the front windshield glass 14 is disposed above the upper surface 88 (dashboard) of the instrument panel 80. The front windshield glass 14 is inclined from the vehicle front lower side toward the vehicle rear upper side.

  As shown in FIG. 1, a combination meter 100 serving as a vehicle display device is disposed in front of the steering hole 16 (in front of the driver's seat) on a vertical wall surface (vehicle rear side surface) 84 of the instrument panel 80. .

  As shown in FIGS. 1 and 2, the instrument panel 80 is provided with a meter hood 88 that projects from the vicinity of the upper side of the combination meter 100 toward the rear of the vehicle and extends in the vehicle width direction. It has been. The meter hood 88 is formed by projecting a part of the upper surface 82 of the instrument panel 80 toward the vehicle rear side (see FIG. 2).

  In addition, as shown in FIG. 2, an instrument panel reinforcement 22 is disposed along the vehicle width direction to reinforce the instrument panel 80 on the vehicle front side of the combination meter 100.

  The combination meter 100 is provided with a display unit 150 (see FIG. 2). The display unit 150 includes various indicators such as various instruments and display lamps, that is, a speedometer, a tachometer, a fuel gauge, a water temperature gauge, a warning lamp, and the like. The display unit 150 has a substantially horizontal plane on the vehicle upper side as a display surface 150A, and the display unit 150 displays various types of information on the display surface 150 by being irradiated by, for example, irradiation means (not shown). .

  As shown in FIG. 2, the combination meter 100 has a substantially U-shaped longitudinal section along the vehicle front-rear direction and is provided with a substantially U-shaped reflecting portion 110 extending in the vehicle width direction.

  Specifically, the substantially U-shaped reflecting portion 110 is configured by arranging three plate-like reflecting mirrors 112, 114, 116 in a substantially U-shape with the reflecting surfaces 112A, 114A, 116A inside. Has been.

  In other words, the substantially U-shaped reflecting portion 110 has the reflecting surface 112A, 114A, 116A arranged in a substantially square cylindrical shape (the inner surface thereof) along the longitudinal direction of the vehicle and the opening 108 on one side of the vehicle interior. It is set as the structure.

  The substantially U-shaped reflecting portion 110 is inclined about the vehicle width direction axis as a whole, and ascending as the reflecting mirrors 112 and 116 move toward the vehicle front side. Further, the substantially U-shaped reflecting portion 110 has an opening 108 on the obliquely lower rear side of the vehicle. The opening 108 is located above the display unit 150.

  A plate-shaped double-sided reflection mirror 120 whose both surfaces are reflection surfaces is provided in the opening 108 of the substantially U-shaped reflection unit 110. The double-sided reflection mirror 120 is rotated by a drive mechanism (not shown). Specifically, the double-sided reflection mirror 120 rotates in both the clockwise and counterclockwise directions, with a rotation shaft 122 extending outward from the center of the end surface in the vehicle width direction as an axis (FIGS. 2 and 3). And).

  Further, when the occupant M operates an operation unit (not shown) provided on the instrument panel 80, the double-sided reflection mirror 120 rotates, and the first angle is made substantially parallel to the reflection mirrors 112 and 116 shown in FIG. And a second angle that is substantially parallel to the reflecting mirror 114 shown in FIG. 3 and closes the opening 108.

  A vehicle rear side of the substantially U-shaped reflecting portion 110 in the vertical wall surface (vehicle rear side surface) 84 of the instrument panel 80 is opened, and an emission portion 85 is formed. The instrument panel reinforcement 22 described above is disposed on the vehicle front side of the substantially U-shaped reflecting portion 110.

  Next, functions and effects of the present embodiment will be described.

  As shown in FIG. 2, when the double-sided reflective mirror 120 is at the first angle, the display (display light) on the display surface 150A of the display unit 150 is reflected by one reflective surface 122A of the double-sided reflective mirror 120, Reflected clockwise with the order of the reflecting surfaces 112A, 114A, 116A, that is, the vehicle width direction as an axis (see arrows L1 to L5). Then, after being reflected by the reflecting surface 116 </ b> A, it is further reflected by the other reflecting surface 120 </ b> B of the double-sided reflecting mirror 120, and is emitted from the opening 108 toward the passenger M through the emitting portion 85 of the instrument panel 80. . This optical path is the first optical path.

  At this time, the occupant M visually recognizes the virtual image K1 of the display unit 150 on the extension line of the display light L6 reflected by the other reflection surface 120A of the double-sided reflection mirror 120. The position of the virtual image K1 is set to the front side of the vehicle by the optical path lengths L1, L2, L3, L4, and L5 from the other reflecting surface 120A of the double-sided reflecting mirror 120. In the present embodiment, the virtual image K1 is located on the vehicle front side of the instrument panel reinforcement 22. Note that the virtual image (display contents) is represented by “arrows” in order to make the vertical direction of the virtual image easy to understand.

  Thus, the virtual image K1 is located on the vehicle rear side with respect to the width in the vehicle front-rear direction of the substantially U-shaped reflector 110. In other words, as compared to the case where the present invention is not applied, the display unit 150 (its virtual image K1) visually recognized by the occupant M with a compact structure can be set as a far viewpoint.

  Moreover, even if it is difficult to secure a long optical path length in the vehicle front-rear direction by arranging the instrument panel reinforcement 22 as in the present embodiment, this configuration is used. The virtual image K1 can be positioned on the front side of the vehicle with respect to the instrument panel reinforcement 22 to provide a far viewpoint.

  On the other hand, as shown in FIG. 3, when the double-sided reflective mirror 120 is at the second angle, the display (display light) on the display surface 150 of the display unit 150 is reflected by one reflective surface 122 </ b> A of the double-sided reflective mirror 120. Then, the light is emitted from the opening 108 toward the occupant M through the emission part 85 of the instrument panel 80. This optical path is the second optical path.

  The optical path length of the second optical path is shorter than that of the first optical path (see FIG. 2), and the virtual image K2 of the display unit 150 viewed by the occupant M is located in the substantially U-shaped reflecting unit 110. That is, it is located on the vehicle rear side (vehicle compartment 12 side) from the virtual image K1 (see FIG. 2) of the first optical path. That is, the virtual image K2 of the display unit 150 that the occupant M visually recognizes is a near viewpoint.

  As described above, the combination meter 100 according to the present embodiment uses the double-sided reflection mirror 120 as the first angle (by using the first optical path), so that the occupant can visually recognize the display unit 150 with a compact structure as the far viewpoint. can do. In addition, by rotating the double-sided reflection mirror 120 approximately 90 ° and switching between the first angle and the second angle, it is possible to switch (select) the far viewpoint (first optical path) and the near viewpoint (second optical path). be able to). In other words, the viewing distance can be switched by rotating the double-sided reflective mirror 120 by approximately 90 °.

  Further, when switching between the first optical path and the second optical path, the angle at which the double-sided reflective mirror 120 is rotated is approximately 90 °. Therefore, switching between the first optical path (first angle, see FIG. 2) and the second optical path (second angle, see FIG. 3) can be performed in a short time. That is, the viewing distance can be switched in a short time.

  Further, since the reflecting surfaces 112A, 114A, 116A, 120A, and 120B are substantially flat, the virtual images K1 and K2 hardly cause distortion. In other words, the distortion of the virtual images K1 and K2 is significantly less than the configuration in which the reflecting surface is a curved surface. Therefore, the visibility is high as compared with the configuration in which the reflection surface is a curved surface.

  Note that the first optical path shown in FIG. 2 is the sum of the reflecting surfaces 112A, 114A, and 116 that constitute the inner surface of the substantially U-shaped reflecting portion 110, one reflecting surface 120A of the double-sided reflecting mirror 120, and the other reflecting surface 120B. Reflects 5 times (reflects odd number of times). On the other hand, the second optical path shown in FIG. 3 is reflected once by one reflecting surface 120 </ b> A of the double-sided reflecting mirror 120. Therefore, the vertical direction of the vehicle coincides between the virtual image K1 (see FIG. 2) of the first optical path and the virtual image K2 (see FIG. 2) of the second optical path.

  Here, since the scenery outside the vehicle viewed from the vehicle interior 12 is a far viewpoint, the display unit 150 of the combination meter 100 is also easy to see because the far viewpoint is easier to focus. Therefore, the first optical path is selected from the viewpoint of the viewing distance (see FIG. 2).

  However, even though the combination meter 100 is provided on the near-view instrument panel 80, if the display unit 150 of the combination meter 100 is at the far viewpoint, some people (occupants M) may feel uncomfortable. . Further, depending on the display contents (for example, numbers and characters) of the display unit 150, there is a case where it is desired to view from a near viewpoint. In such a case, the second optical path that is the near viewpoint is selected (see FIG. 3). That is, the viewing distance can be switched according to the preference of the occupant M and the display content.

  Next, a combination meter as a vehicle display device according to the second embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5. 4 and 5 are longitudinal sectional views schematically showing a longitudinal section of the instrument panel along the line AA shown in FIG. 1 (along the vehicle longitudinal direction). In addition, an arrow UP in the figure indicates the upward direction of the vehicle, and an arrow FR indicates the forward direction of the vehicle. In addition, the same code | symbol is used for the same member as 1st embodiment, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 4, the combination meter 200 according to the second embodiment has a substantially U-shaped longitudinal section along the vehicle front-rear direction, and is provided with a substantially U-shaped reflecting portion 210 extending in the vehicle width direction. ing.

  Specifically, as in the first embodiment, the substantially U-shaped reflecting portion 210 includes three plate-like reflecting mirrors 112, 114, and 116, the reflecting surfaces 112A, 114A, and 116A on the inner side. It is comprised by arranging in a shape. In other words, the substantially U-shaped reflecting portion 210 has the reflecting surfaces 112A, 114A, and 116A arranged in a substantially square (inner surface) in the longitudinal section along the vehicle front-rear direction, and one side on the vehicle interior side is the opening 108. It has been configured.

  The reflection mirror 114 disposed at a position facing the opening 108 of the substantially U-shaped reflection unit 210 is translated (slid) by a drive mechanism (not shown). Specifically, it is possible to move between a first position shown in FIG. 4 and a second position shown in FIG. 5 that translates (slides) to substantially close the opening 108.

  In addition, when the passenger | crew M operates the operation part (not shown) provided in the instrument panel 80, the reflective mirror 114 moves between the 1st position shown in FIG. 4, and the 2nd position shown in FIG. Slide).

  Next, functions and effects of the present embodiment will be described.

  As shown in FIG. 4, when the reflecting mirror 112 is in the first position, the display (display light) on the display surface 150 of the display unit 150 is centered on the order of the reflecting surfaces 116A, 114A, 112A, that is, the vehicle width direction. As counterclockwise (see arrows G1 to G3). Then, after being reflected by the reflecting surface 112 </ b> A, the light is emitted from the opening 108 toward the occupant M through the emission part 85 of the instrument panel 80. This optical path is the first optical path.

  At this time, the virtual image K3 of the display unit 150 is visually recognized on the extension line of the display light G4 reflected by the reflecting surface 114A of the occupant M reflecting mirror 112. The position of the virtual image K3 is set to the front side of the vehicle by the optical path length of the display lights G1, G2, and G3 from the reflection surface 112A of the reflection mirror 112.

  Thus, the virtual image K3 is located on the vehicle rear side with respect to the width of the substantially U-shaped reflecting portion 110 in the vehicle front-rear direction. In other words, as compared with the case where the present invention is not applied, the display unit 150 (its virtual image K3) visually recognized by the occupant M with a compact structure can be a far viewpoint.

  On the other hand, as shown in FIG. 5, when the reflection mirror 112 is in the second position, the display (display light) on the display surface 150A of the display unit 150 is reflected by the reflection surface 112A of the reflection mirror 112, and the opening portion. From 108, toward the occupant M, the light is emitted through the emission part 85 of the instrument panel 80. This optical path is the second optical path.

  The optical path length of the second optical path is shorter than that of the first optical path (see FIG. 4), and the virtual image K2 of the display unit 150 visually recognized by the occupant M is located in the substantially U-shaped reflecting unit 110. That is, it is located on the vehicle rear side (vehicle compartment 12 side) significantly from the virtual image K3 (see FIG. 4) of the first optical path. That is, the virtual image K2 of the display unit 150 that the occupant M visually recognizes is a near viewpoint.

  Thus, the combination meter 200 of this embodiment can make the display part 150 (the virtual image K3) visually recognized by the occupant with a compact structure as a far viewpoint. In addition, by moving the reflecting mirror 112 in parallel, it is possible to switch (select) the far viewpoint (first optical path) and the near viewpoint (second optical path). In other words, the viewing distance can be switched by moving the reflecting mirror 112 in parallel.

  Note that the first optical path shown in FIG. 4 is reflected a total of three times (reflects an odd number of times) on the reflecting surfaces 112A, 114A, and 116A that constitute the inner surface of the substantially U-shaped reflecting portion 210. On the other hand, the second optical path shown in FIG. 3 is reflected once by the reflecting surface 122A of the reflecting mirror 112. Therefore, the vertical direction of the vehicle coincides between the virtual image K3 (see FIG. 4) of the first optical path and the virtual image K2 (see FIG. 5) of the second optical path.

  Moreover, since selection of a 1st optical path and a 2nd optical path is the same as that of 1st embodiment, description is abbreviate | omitted.

  Next, a first modification and a second modification of the second embodiment will be described.

  First, the combination meter 220 of the first modification will be described with reference to FIG. As shown in FIG. 6, the combination meter 220 of the first modified example has a substantially U-shaped longitudinal section along the vehicle front-rear direction and is provided with a substantially U-shaped reflecting portion 222 extending in the vehicle width direction. ing.

  The reflection mirror 116 at the upper part of the substantially U-shaped reflection part 222 is rotated about a rotation shaft 224 near the vehicle rear end of the reflection mirror 116 by a drive mechanism (not shown). Specifically, a first position (see FIG. 4) that constitutes a substantially U-shaped upper portion and a second position that rotates approximately 90 ° and closes the opening 108 as shown in FIG. It is possible to rotate between them.

  In addition, when the passenger | crew M operates the operation part (not shown) provided in the instrument panel 80, the reflective mirror 116 rotates between the 1st position and the 2nd position.

  Next, functions and effects of the present embodiment will be described.

  Since the first optical path is the same as that of the second embodiment, description thereof is omitted. As shown in FIG. 6, when the reflection mirror 116 is in the second position, the display (display light) on the display surface 150 </ b> A of the display unit 150 is reflected by the reflection surface 116 </ b> A of the reflection mirror 116 and The light is emitted through the emission part 85 of the instrument panel 80 toward the passenger M. The optical path is the second optical path.

  Next, a combination meter 230 according to a second modification will be described with reference to FIG. FIG. 7 is a vertical cross-sectional view schematically showing a vertical cross section of the instrument panel along the line AA shown in FIG. 1 (along the vehicle longitudinal direction). In addition, an arrow UP in the figure indicates the upward direction of the vehicle, and an arrow FR indicates the forward direction of the vehicle.

  As shown in FIG. 7, the combination meter 320 of the second modified example has a substantially U-shaped longitudinal section along the vehicle front-rear direction, and is provided with a substantially U-shaped reflecting portion 322 extending in the vehicle width direction. ing.

  The reflection mirror 112 below the substantially U-shaped reflection part 322 is rotated about a rotation shaft 324 in the vicinity of the vehicle rear end of the reflection mirror 112 by a drive mechanism (not shown). Specifically, a first position (see FIG. 4) that constitutes a substantially U-shaped lower portion and a second position that rotates about 90 ° and closes the opening 108 as shown in FIG. It is possible to rotate between them.

  In addition, when the passenger | crew M operates the operation part (not shown) provided in the instrument panel 80, the reflective mirror 112 rotates between a 1st position and a 2nd position.

  Next, functions and effects of the present embodiment will be described.

  Since the first optical path is the same as that of the second embodiment, description thereof is omitted. As shown in FIG. 7, when the reflection mirror 112 is at the second position, the display (display light) on the display surface 150 </ b> A of the display unit 150 is reflected by the reflection surface 112 </ b> A of the reflection mirror 112, and from the opening 108. The light is emitted through the emission part 85 of the instrument panel 80 toward the passenger M. This optical path is the second optical path.
