Then, the display design portion D is provided by the first punched portion (pulled portion) 25a of the opaque portion 25 in which the opaque portion 25 is not partially formed (see FIG. 3). That is, in the case of this example, the second region R2 described above is provided with the opaque portion 25 that blocks the illumination light except for the portion that becomes the display design portion D.

The display design unit D constitutes various indicator display units for notifying the vehicle state. As an example, in the case of this example, a pair of arrow marks (notification marks) indicating the operating state of the direction indicator. Direction instruction preparations D1 and D2, neutral design D3 which is a notification mark indicating that the gear position is in the "N (neutral)" position, and indicating that the optical axis direction of the headlight is in the high beam position. It is composed of a high beam design D4 which is a notification mark.

Further, in this case, the notification light source 23 is provided corresponding to each display design unit D, that is, four display design units including the direction instruction preparation designs D1 and D2, the neutral design D3, and the high beam design D4. Four notification light sources 23 are provided so as to correspond to D respectively. The notification light source 23 corresponding to the direction instruction preparation designs D1 and D2 is a green LED that emits green light, and the notification light source 23 corresponding to the neutral design D3 and the high beam design D4 is a blue LED that emits blue light.

The intermediate layer 26 is provided on the front side of the opaque portion 25 so as to overlap the forming range of the opaque portion 25. The intermediate layer 26 is provided to prevent the opaque portion 25 from being seen through the half mirror layer 24 from the front side. The intermediate layer 26 is provided with a second punched portion 26a in a region corresponding to the first punched portion 25a of the opaque portion 25 (see FIG. 3).

The partition wall 27 is a wall portion that partitions an illumination space for illuminating each display design including the direction-indicating preparation designs D1 and D2, the neutral design D3, and the high beam design D4.

The instrument housing 30 includes a first instrument housing 31 inclined so as to accommodate the display means 10, and a second instrument housing 32 located below the first instrument housing 31.

The first instrument housing 31 is, for example, a resin case made of a black synthetic resin material, and has a substantially concave shape with the display means 10 side open.

The second instrument housing 32 includes the above-mentioned translucent portion 21 which is a part located on the most front side thereof, and a housing portion 33 for accommodating the circuit board 22, the notification light source 23, the partition wall 27, and the like. Be prepared.

The protective member 40 is a substantially flat protective panel member formed of a translucent synthetic resin material and provided so as to cover the front side of the display means 10. A black light-shielding layer 41 that surrounds the peripheral edge of the display surface 11 is provided on the rear peripheral edge portion of the protective member 40. In FIG. 2, 50 is a support that supports the first instrument housing 31, and the support 50 is placed on the first housing 34.

The vehicle instrument M is composed of the above parts. In such a configuration, when all the notification light sources 23 are turned off, nothing is displayed on the half mirror layer 24 when the half mirror layer 24 is viewed from the front side (see FIG. 1). ..

On the other hand, when the notification light source 23 is turned on, when the half mirror layer 24 is viewed from the front side, the display design unit D emits light and displays on the half mirror layer 24. Specifically, the light emitted from the notification light source 23 when the notification light source 23 is lit travels to the front side (transmissive portion 21 side) through the illumination space. The light traveling to the front side (transmissive portion 21 side) passes through the half mirror layer 24 through the punching portions 25a and 26a and the translucent portion 21, and thus the half mirror layer 24 is viewed from the front side. At that time, the display design unit D is light-emittingly displayed on the half mirror layer 24 (see FIG. 4).

In FIG. 4, when all the notification light sources 23 are turned on (the control unit 22a detects the hazard switch on operation signal and also detects a predetermined headlight operation signal such that the headlight is in the high beam position). However, when a gear position signal indicating that the gear position is in the neutral position is detected), the information displayed on the half mirror layer 24 (direction instruction preparations D1, D2, neutral design D3, high beam design D4). ) Is shown.

Actually, among these, the direction instruction preparations D1 and D2 are displayed by emitting light in a blinking state. That is, under the control of the control unit 22a, the notification light source 23 corresponding to the direction instruction preparations D1 and D2 is intermittently turned on.

As described above, in the present embodiment, the display means 10, the notification means 20 provided so as not to overlap with the display means 10 when viewed from the front side, and the instrument housing 30 accommodating at least the display means 10 are provided. The notification means 20 includes a translucent portion 21 formed in the required portion of the instrument housing 30, and a half mirror layer (semi-transmissive portion) 24 formed in the first region R1 facing the front side of the translucent portion 21. A notification light source 23 for supplying illumination light to a second region R2 opposite to the first region R1 of the translucent portion 21 is provided, and a predetermined display design is provided in the second region R2. The opaque portion 25 that blocks the illumination light is provided except for the portion that becomes the display design portion D that forms the above.

Therefore, when the notification light source 23 is turned off, the display design unit D is invisible when the half mirror layer 24 (notification means 20) is viewed from the front side (viewer side), and the notification light source 23 is lit. Since the display design unit D becomes visible only when the display design unit D is visible, it is suppressed that the display design unit is slightly visible when the notification light source is turned off as in the conventional case, and the appearance quality of the vehicle instrument M has a high-class appearance. Therefore, it is possible to provide the vehicle instrument M with improved commercial value.

Further, in the present embodiment, the first region R1 (half mirror layer 24) has a non-flat shape (curved surface shape that is convex to the front side), so that the half mirror layer is formed when the notification light source 23 is lit. There is an advantage that the display design unit D, which is light-emittingly displayed on the 24th screen, is enlarged and the display quality is improved.

The present invention is not limited to the above-described embodiments and drawings. Changes (including deletion of components) can be made to the embodiments and drawings as appropriate without changing the gist of the present invention.

For example, in the above-described embodiment, when the half mirror layer 24 is viewed from the front side, the translucent portions 21 (each punched portions 25a and 26a) and the circuit board 22 are in a positional relationship so as to overlap each other. The positional relationship between the translucent portion 21 and the circuit board 22 is not limited to this as long as the illumination light can be guided to the translucent portion 21.

For example, as shown in FIG. 5 as a modification of the present embodiment, the circuit board 22 is arranged on the bottom wall 35a (or in the vicinity of the bottom wall 35a) so as to be substantially parallel to the bottom wall 35a, and the circuit board 22 is arranged. The notification light source 23 may be mounted on the surface facing the first housing 34 side, and the light guide member 60 may be arranged in the optical path of the illumination light from the notification light source 23 to the translucent portion 21. A plurality of light guide members 60 here are provided for each display design unit D.

The light guide member 60 is directed toward the notification light source 23 side from, for example, a main body portion 61 located behind the light transmitting portion 21 (each punching portion 25a, 26a) and an end portion located behind the main body portion 61. It has a light receiving portion 62 that protrudes from the light receiving portion 62, and a reflecting portion 63 for guiding the illumination light taken into the light guide member 60 through the light receiving portion 62 to the main body portion 61.

That is, when the notification light source 23 is lit, the illumination light emitted from the notification light source 23 is taken into the light guide member 60 through the light receiving unit 62, and the main body 61 is moved forward in a state where the optical path is bent by the reflection unit 63. Proceeding toward the side, the light is emitted from a flat (or curved surface having a convexly curved front side) light emitting portion 61a provided on the front side of the main body 61. Then, the emitted light emitted from the light emitting portion 61a in this way passes through the half mirror layer 24 via the respective extraction portions 26a and 25a and the translucent portion 21, whereby the half mirror layer 24 is transmitted as in the above embodiment. The display design unit D is light-emittingly displayed. Even in the case of such a configuration, the same effect as that of the above-described embodiment can be obtained.
