  As shown in FIG. 2, the cover 31 covers the back side of the through hole 30 b of the main body 30. In the display device 1, the front side is the driver side or the passenger compartment side, and typically indicates the rear side in the vehicle front-rear direction. The back side is the opposite side to the front side, and typically indicates the front side in the vehicle front-rear direction. The cover part 31 is fixed to the main body part 30. The cover 31 has a through hole 32 through which the rotary shaft 5a of the pointer 5 is inserted.

  The display device 1 further includes a display plate 10, a substrate 11, and a light source 12. The display board 10 is disposed on the back side of the cover portion 31. The display board 10 has a plurality of indicators 10a for displaying information. The indicator 10a is a display unit that emits light in the shape of an indicator design. The indicator design displays information such as various warnings related to the vehicle and the operating state of the device, for example, with a design or the like. The display board 10 includes, for example, a transparent resin board main body and a printing unit on which dark ink is printed on the board main body. The printing part has a hollow printing part in the shape of the indicator design. The indicator 10a of the present embodiment is this hollow print section.

  The cover part 31 covers the front surface of the indicator 10a. That is, the cover 31 is disposed in a region facing the indicator 10 a in the circular display unit 3. In other words, the cover 31 is provided in a region of the dial 7 that faces the indicator 10a. In the circular display portion 3 of the present embodiment, the region of the through hole 30b is a region facing the indicator 10a, in other words, a region on the front side of the indicator 10a.

  The substrate 11 and the light source 12 are disposed on the back side of the display board 10. The light source 12 is, for example, an LED (light emitting diode) and is fixed to the substrate 11. Light sources 12 are arranged at positions facing the substrate 11 with respect to the plurality of indicators 10a. The light source 12 irradiates the indicator 10a with light from the back side. The indicator 10 a emits light by light from the light source 12. That is, the indicator 10a as a display unit emits light in the shape of an indicator design by light irradiated from the back side.

  The substrate 11 has a control circuit that controls turning on and off of the light source 12. The board | substrate 11 switches the display and non-display of the indicator 10a by making each light source 12 light or extinguish.

  As shown in FIG. 3, the cover 31 is configured by weaving fibers 33. In the cover portion 31 of the present embodiment, the fibers 33 are plain woven. As shown in FIG. 3, a gap 34 exists between the adjacent fibers 33. The shape of the gap 34 in plan view is a rectangle, for example, a substantially square. In the cover portion 31 of the present embodiment, gaps 34 having the same size and shape are regularly arranged at equal intervals. The arrangement direction of the gaps 34 is a direction in which the fibers 33 extend.

  In the present embodiment, the width W1 of the gap 34 is the same as or slightly narrower than the width W2 of the fibers 33. The width W1 and the width W2 are average width values of the gap 34 and the fiber 33, respectively. Alternatively, the width W1 and the width W2 may be the minimum width value or the maximum width value of the gap 34 and the fiber 33.

  As shown in FIG. 4, the cover 31 is a plate-like or sheet-like member. As shown in FIG. 4, the cover 31 has a metal film 35 formed on the front side. The fiber 33 of the present embodiment is a transparent or translucent resin fiber, and is made of, for example, a synthetic resin. The material of the fiber 33 is, for example, polyester, polyethylene, nylon, or acrylic. Examples of the polyester include PET (polyethylene terephthalate). Examples of polyethylene include fluororesins such as PP (polypropylene) and PTFE (polytetrafluoroethylene). The fibers 33 may be colorless and transparent or translucent, or colored and transparent or translucent. The metal film 35 is a film formed on the front surface of the fiber 33. The metal film 35 of this embodiment is formed by sputtering. A metal film 35 is formed on one surface of the fabric of the fibers 33 by sputtering. The metal film 35 is made of a metal such as aluminum or stainless steel, for example.

  The metal film 35 of the present embodiment is a semi-transmissive film that transmits light from the back side to the front side. The thickness and the like of the metal film 35 are adjusted so that the metal film 35 is semi-transmissive and transmits part of light and reflects part of light. In the cover part 31, the fiber 33 is transparent or semi-transparent, and the metal film 35 has translucency. Therefore, the entire cover portion 31 is light transmissive. The light Lt1 emitted from the indicator 10a is transmitted through the fibers 33 and the metal film 35 of the cover 31 as shown in FIG. 4 (see arrow Y1). The light Lt1 passes through the gap 34 between the fiber 33 and the adjacent fiber 33 (see arrow Y2). Thus, the cover part 31 of this embodiment allows the light Lt1 of the indicator 10a that emits light to pass to the front side. The cover portion 31 can pass the light Lt1 of the indicator 10a in the display state entirely without being blocked.

  Since the metal film 35 has translucency, it reflects the light Lt2 incident from the front side toward the front side (see arrow Y3). Therefore, the metal film 35 is glossed by the reflected light, and produces a metallic appearance mainly in the non-display state of the indicator 10a. That is, the metal film 35 is glossy on the front surface of the cover part 31, and can be seen as if the cover part 31 is made of metal.

  Moreover, the cover part 31 has covered the front surface of each indicator 10a integrally. The sheet-like cover part 31 covers and hides the non-display state indicator 10a, thereby making the non-display state indicator 10a inconspicuous. The non-display indicator 10a is not illuminated by the light source 12 and does not emit light. Therefore, the cover part 31 that reflects the light from the front side can hide the indicator 10a that does not emit light behind and make it inconspicuous. Moreover, since the cover part 31 is comprised by weaving the fiber 33, it has a three-dimensional effect. The covering portion 31 rich in three-dimensional effect can make the planar indicator 10a behind it inconspicuous. By adjusting the reflectance of the metal film 35, or adjusting the width W1 of the gap 34 and the width W2 of the fiber 33, the indicator 10a in the non-display state can be made substantially invisible from the passenger compartment side. Is possible.

  As described above, the display device 1 according to the present embodiment can sufficiently ensure the visibility of the indicator 10a in the display state without inhibiting the passage of the light Lt1 of the indicator 10a in the display state. On the other hand, the display device 1 can cover and hide the indicator 10a in the non-display state to make its presence inconspicuous. Since the cover part 31 is formed by weaving the fibers 33, it has a three-dimensional effect. Therefore, the display device 1 of the present embodiment can improve the design of the display device 1 while ensuring the visibility of the display content by the indicator 10a as a display unit.

  FIG. 5 and FIG. 6 each show a display state indicator 10a. 5 and 6, the thickness of the fiber 33 of the covering portion 31, that is, the fineness of the weave is different. The thickness of the fiber 33 of the cover part 31 shown in FIG. 6 is thicker than the thickness of the fiber 33 of the cover part 31 shown in FIG. The texture of the cover part 31 shown in FIG. 6 is coarser than the texture of the cover part 31 shown in FIG. As can be seen from FIGS. 5 and 6, the covering portion 31 (FIG. 5) in which the fibers 33 are thin is less conspicuous than the covering portion 31 (FIG. 6) in which the fibers 33 are thick, and the visibility of the indicator 10 a is not easily disturbed. On the other hand, the covering portion 31 with the thick fibers 33 is richer in stereoscopic effect than the covering portion 31 with the thin fibers 33. It is desirable that the thickness of the fibers 33 and the fineness of the texture be set so that the visibility of the indicator 10a can be ensured in the cover portion 31 and the design can be improved due to the three-dimensional effect.

  As described above, the display device 1 according to the present embodiment is configured by weaving the indicator 10a that emits light emitted from the back side and the fibers 33, covers the front surface of the indicator 10a, and emits light. And a cover portion 31 that allows the light to pass to the front side. Since the cover portion 31 is configured by weaving the fibers 33, the cover portion 31 has a three-dimensional feeling and a texture. Therefore, the display device 1 of the present embodiment is excellent in design. Moreover, since the cover part 31 passes the light which the indicator 10a light-emits to the front side, it is hard to inhibit the visibility of the indicator 10a.

  In the display device 1 according to the present embodiment, the cover portion 31 has light transparency and transmits the light of the indicator 10a from the back side to the front side. The light-transmitting cover 31 can improve the visibility of the indicator 10a that emits light.

  The cover part 31 of this embodiment is configured by weaving transparent or translucent resin fibers, and a metal film 35 is formed on the front surface of the cover part 31. The metal film 35 formed on the front surface of the cover 31 produces a metallic appearance and improves the design of the display device 1.

  In the display device 1 of the present embodiment, the display unit is an indicator 10a that is arranged on the back side of the dial 7 of the vehicle meter and displays information. The cover 31 is disposed in a region of the dial 7 that faces the indicator 10a. Thus, when the display device 1 is applied to a vehicle meter, the design of the vehicle meter can be improved.

[Second Embodiment]
A display device 1 according to the second embodiment will be described with reference to FIG. In the second embodiment, components having the same functions as those described in the first embodiment are given the same reference numerals, and duplicate descriptions are omitted. FIG. 7 is a cross-sectional view of the cover according to the second embodiment.

  In the cover part 31 shown in FIG. 7, the metal film 36 does not have optical transparency. In other words, the metal film 36 does not allow light transmission from the back side to the front side. Therefore, of the light Lt1 emitted from the indicator 10a, the passing light (see arrow Y4) passing through the gap 34 is visually recognized from the vehicle compartment side. On the other hand, of the light Lt1 emitted from the indicator 10a, the light traveling toward the fiber 33 is not transmitted to the front side.

  In the cover part 31 of the second embodiment, the metal film 36 is impermeable. For this reason, the metal film 36 has higher reflectivity than the metal film 35 of the first embodiment. Therefore, the metal film 36 of the second embodiment is more advantageous in producing a metallic tone than the metal film 35 of the first embodiment. In the cover part 31 of 2nd Embodiment, the fiber 33 may not have light transmittance.

[Modification of each embodiment]
A modification of the first embodiment and the second embodiment will be described. The weaving method of the fibers 33 is not limited to the plain weave exemplified in the above embodiment. The fibers 33 may be woven by a weaving method such as twill weaving. The weaving method of the fibers 33 is not limited to a regular one. The cover 31 may include fibers 33 having different thicknesses or may include fibers 33 of different materials. The cover 31 may be woven with fibers 33 on which metal films 35 and 36 are formed in advance. In this case, if the fiber 33 is a transparent or translucent resin fiber, it is desirable to form a semipermeable metal film 35 on the surface of the fiber 33.

  The metal films 35 and 36 may be formed on the back surface instead of the front surface of the cover portion 31. Even when the metal films 35 and 36 are formed on the back surface, the cover 31 is glossy by the reflected light of the metal films 35 and 36 and can produce a metallic tone.

  The metal film 35 and the metal film 36 may not be formed on the surface of the fiber 33. In this case, the fibers 33 may be colored from the viewpoint of improving the luxury and texture. The “colored” here includes white and black. In the colored cover portion 31, the resin constituting the fiber 33 may be colored in advance, or the surface of the resin fiber 33 may be colored. The color of the fiber 33 may be a dark color, for example.

  The material of the fiber 33 is not limited to resin. For example, the fiber 33 may be a metal fiber. That is, the cover part 31 may be configured by weaving metal fibers. In this case, the cover 31 may not have the metal films 35 and 36.

  The area where the indicator 10 a and the cover part 31 are arranged is not limited to the inner part of the circular display part 3. For example, the indicator 10 a and the cover part 31 may be arranged in a region outside the circular display part 3 on the dial 7. That is, the indicator 10 a and the cover portion 31 may be provided in any region of the dial 7.

  The cover part 31 may be fixed to another member such as the display panel 10 instead of being fixed to the main body part 30.

  The display unit is not limited to the illustrated indicator 10a. The display unit may be a liquid crystal display unit, for example. The display device 1 is not limited to a meter, and may be another display device arranged in a vehicle. Moreover, the display apparatus 1 is not limited for vehicles. The display device 1 may be applied to a product having a display unit that emits light, such as a household or business appliance.

  The contents disclosed in the above embodiments and modifications can be executed in appropriate combination.
