The light source 5c is turned on in response to an external signal, and road guidance is provided to the driver of the vehicle on the display 5a. To be displayed.

  The main components of the meter unit 1 have been described above. Next, the manner in which characters such as the speedometer 2 are illuminated with light and displayed will be described. In the speedometer 2, as shown in FIG. 1B, for example, the light from the light source L1 is reflected by the back surface B of the reflector R1 (main body 2e1), and the reflector R2 (main body) adjacent to the right side of the reflector R1 in the drawing. 2e1). Then, the incident light is reflected by the surface S of the reflection plate R2 (the main body 2e1) and enters the display plate 2a. In the speedometer 2, a set of a reflector 2e and a light source 2d located on the back side (lower side in the figure) of the reflector 2e is arranged around the axis O in FIG. 1A, and the reflector 2e covers the light source 2d in FIG. 1B. Light is applied to the display panel 2a in front of (upper side in the figure). When the display panel 2a is irradiated with light, the light leaks from the number N and the scale S shown in FIG. 1A which is a light transmitting portion of the display panel 2a, so that the number N and the scale S are displayed so as to shine. It is displayed on the board 2a. Although the speed meter 2 has been described as an example, the same applies to the tachometer 3.

  On the other hand, in the odometer 4, light from the light source 4c on the left side of the figure shown in FIG. 5 is reflected by the back surface B of the main body 4d1, and enters the surface S of the main body 4d1 adjacent to the right side of the main body 4d1 in the figure. Then, the incident light is reflected by the surface S of the main body 4d1 and enters the display 4a. In the odometer 4, a set of a reflection plate 4d and a light source 4c located on the back side (lower side in the figure) of the reflection plate 4d is arranged linearly along the in-plane direction of the display 4a, and the reflection covering the light source 4c is provided. The display 4a in front of the plate 4d (upper side in FIG. 5) is irradiated with light. The emitted light serves as a backlight for the display 4a, so that the total traveling distance of the vehicle is displayed on the display 4a. Although the odometer 4 has been described as an example, the same applies to the device 5 for road guidance.

  In the meter unit 1, as shown in FIG. 1B, the light source L2 is covered from the front (upper side in the figure), and a reflector R2 that reflects light from the light source L2 to the right side in the figure is reflected from the light source L1 reflected by the reflector R1. Reflects light forward. Therefore, light can be emitted to the front (upper side in the figure) of the reflector R2 located so as to cover the front side (upper side in the figure) of the light source L2. As shown in FIGS. 1A and 1B, the light source 2d and the set of the reflectors 2e located in front of the light source 2d are arranged annularly around the axis O, so that light can be emitted in front of each set of the reflectors 2e. Since the reflecting plate 2e is arranged in a discontinuous arc shape so as to follow the trajectory drawn by the tip of the pointer 2c rotating about the axis O in FIG. 1A, light is emitted along the trajectory drawn by the tip of the pointer 2c. Can be irradiated. Further, as shown in FIG. 1A, the number N and the scale S of the display panel 2a are arranged along the outer periphery of the trajectory drawn by the tip of the pointer 2c, so that the number N and the scale S are effectively illuminated with respect to the number N and the scale S. Can be illuminated. As a result, light leaks from a portion of the number N and the scale S through which light is transmitted, and the number N and the scale S can be made to shine strongly. For example, in a conventional display device as disclosed in Patent Document 1, it is difficult to strongly illuminate a number or the like disposed on the outer peripheral portion of the pointer because the light source is disposed near the rotation axis. However, in the meter unit 1, the number N and the scale S can be strongly illuminated. Further, in the meter unit 1, not only the numeral N and the scale S, but also the displays 4a and 5a shown in FIGS. 5 and 7 can be strongly illuminated. The reflecting plate 2e and the like for reflecting light from the light source 2d and the like illuminating the numeral N and the like are, for example, plate-shaped main bodies 2e1 inclined with respect to the plane P as shown in FIG. The display plate 2a and the like can be illuminated by the plate 2e and the like. The light applied to the display panel 2a includes not only the light reflected from the reflection plate 2e but also the light applied to the display panel 2a directly from the light source 2d. Can be displayed. Therefore, there is no need to provide a member for diffusing light, which was conventionally required. Further, since the front of the light source 2d is covered with the reflector 2e, it is difficult for the occupant of the vehicle to directly recognize the light source 2d.

  Further, as shown in FIG. 9, the shape of the reflecting plate 2e may be the same as the angle at which the front surface S is inclined with respect to the plane P and the angle at which the back surface B is inclined with respect to the plane P. . By changing the angle, the direction in which light is reflected on the front surface S and the back surface B can be changed. When the distance D1 of the gap between the display plate 2a and the reflection plate 2e shown in FIG. 9 is adjusted, the light applied to the display plate 2a can be adjusted.

  In the above description, as an example of the light transmitting portion that transmits light, an example is shown in which the numbers N and the like are displayed in a discontinuous arc shape around the rotation axis 2b in FIG. 1A. It may be displayed in a continuous ring. In addition to the numeral N or the like, a continuous arc or ring (for example, an arc or ring that is not cut off) around the rotation axis 2b may be displayed on the display panel 2a or the like. Etc. and decorations may be combined.

  In the above description, as shown in FIGS. 1A and 1B, an example is shown in which the set of the light source 2d and the reflector 2e located in front of the light source 2d is arranged in a ring, but may be arranged in an arc. Good. In addition, as shown in FIGS. 5 and 6, an example is shown in which a set of a light source 4c and a reflector 4d located in front of the light source 4c is linearly arranged. It is possible to adopt.

  In the above description, an example is shown in which the numbers N and the like are arranged along the outer periphery of the locus drawn by the tip of the pointer 2c in FIG. 1B. However, the number N is arranged along the inner periphery of the locus or along the locus. Etc. may be arranged. Also, an example has been shown in which the set of the light source 2d and the reflector 2e located in front of the light source 2d is arranged along the inner periphery of the trajectory drawn by the tip of the pointer 2c. The trajectory to be drawn or the outer periphery of the trajectory may be arranged.

  In the above description, an example in which only the reflection plate 2e is provided on the plate portion 6 in FIG. 3 has been described. However, the reflection plate 2e is combined with the reflection plate 4d in FIG. 5 and the reflection plate 5d in FIG. It may be a unit. By combining the reflection plates 2e, 4d, and 5d into one plate portion, the attachment of the reflection plates 2e, 4d, and 5d becomes easy.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the specific description, and may be implemented by appropriately combining the exemplified configurations, processes, and the like within a technically consistent range. It is possible, and it is also possible to replace some elements and processing with a known form and carry out the processing.

  In the above description, as an example of the reflection unit, the reflection plate 2e or the like whose front and back surfaces are reflection surfaces is illustrated. However, a magic mirror such as a half mirror that transmits a part of incident light may be used. When a magic mirror is used for the reflection unit, light transmitted through the magic mirror is incident on the display plate 2a directly above the light source 2d (upper side in FIG. 1B), and can illuminate the display plate 2a.
