- the inclined surface 10 in the V-shaped cut 5b1 it is desirable to mirror-finish the inclined surface 10 in the V-shaped cut 5b1 to form a mirror surface, and to reflect the illumination light with this mirror surface, but this is a simple cut surface for molding and a rough surface as a special mirror surface. You do not have to be fine.
- the embossed portion on the inclined surface 10 of the V-shaped cut 5b1 the entire emboss shines during night illumination, and the entire emboss can be seen, and a different three-dimensional effect can be produced.
- mirror printing may be performed so as to form a bright printing film on the inclined surface 10 of the V-shaped cut 5b1.
- a mirror surface ink may be sprayed so that the coating film adheres to the inner surface of the unmasked V-shaped cut 5b1.
- the brilliance of the inclined surface 10 is emphasized by forming the mirror film printing with brilliance and the spray coating film of the mirror surface ink on the inclined surface 10 of the V-shaped cut 5b1, and the three-dimensionally marked portion 5 is further enhanced. Can be made visible.
- edge light illumination may be combined with backlight illumination illuminated from the back side of the display board 1.
- the above configuration is adopted for a vehicle instrument of a type in which illumination light guided into the inside of the pointer is emitted from the tip of the pointer 4 and the indicator 4 is indicated by the light from the tip of the pointer.
- the reflection of the V-shaped cut 5b1 may be emphasized.
- the color of the illumination light may be changed during display.
- the present invention can be applied to other instruments such as engine tachometers (tachometers) and fuel meters.
- the inclined surface may be a gentle curved surface instead of a tapered surface.
- the above configuration can also be used for an instrument in which the pointer points to the indication part that is not a number such as E or F.
- there may not be a pointer, and the transition of the lighting positions of a plurality of light emitting diodes that indicate the position of the index may be substituted for the pointer.
- An edge-light illumination type vehicle instrument for introducing illumination light into the display plate from the side of the display plate, which is provided on the back side of the display plate, as a marking portion and a marking portion as indicators.
- the three-dimensional display unit is provided on the back side of the display board side by side and displays the indication section in three dimensions.
- the three-dimensional display section is recessed from the back side to the front side of the display board It consists of a hollow of a V-shaped cross section having an inclined inclined surface, and the illumination light introduced through the edge portion of the display plate is reflected by the inclined surface and the marking portion toward the surface side of the display plate.
- the three-dimensional display portion is recessed from the back surface side to the front surface side of the display plate, and comprises a recess having a V-shaped cross section with an inclined surface inclined with respect to the plane direction of the display plate Since the illumination light introduced through the unit is reflected by the inclined surface and the writing unit and travels to the surface side of the display plate, the writing unit can be viewed three-dimensionally by the three-dimensional display unit and via the edge of the display plate. The illumination light guided to the inside of the display plate is reflected by the inclined surface, and the three-dimensional display unit is visually recognized to glow at night. When the edge light is not illuminated, the stereoscopic display scatters extraneous light. As a result, it is possible to change the appearance between day and night, and to provide a vehicle instrument in which the indication portion printed on the display plate looks three-dimensional.
- the three-dimensional display unit may be formed at a position corresponding to the shadow of the writing portion on the opposite side of the writing portion in the plane direction with respect to the side on which the light is virtually irradiated to the display plate.
- the stereoscopic display unit is formed at a position corresponding to the shadow of the writing portion on the opposite side across the writing portion in the plane direction with respect to the side to which light is virtually irradiated.
- the three-dimensional display unit makes it easy to view the notation portion in three dimensions.
- a contour line indicating the contour of the writing portion may be formed on the opposite side of the writing portion in the plane direction to the side opposite to the three-dimensional display portion. According to this configuration, since the outline indicating the outline of the writing part is formed on the opposite side to the three-dimensional display part across the writing part in the planar direction, the outline of the writing part is the outline and the solid The display unit makes the display clearer and easier to read.
- the display portion includes a central colored portion that is colored and a peripheral colored portion that surrounds the periphery of the central colored portion and that has a higher reflectance of the illumination light than the central colored portion, and the three-dimensional display A part may be formed at least in part around the surrounding colored part.
- the mark portion includes the central coloring portion and the peripheral coloring portion surrounding the periphery of the central coloring portion, and the three-dimensional display portion is formed at least at a part of the periphery of the peripheral coloring portion. Since the surrounding colored parts are visible on the table and the central colored parts appear to be on the table, the inscription part is more visible in three dimensions.
- the maximum width in the planar direction of the depression forming the three-dimensional display portion may have a width of 25% to 75% of the maximum width in the planar direction of the central coloring portion.
- the three-dimensional display unit is formed of a groove-like depression, and the maximum width of the groove has a width of at least 25% to 75% of the maximum width of the central colored portion, so the three-dimensional display unit is sufficiently three-dimensional
- the display and the inclined surface are sufficiently reflected to enable display as an index of a high-quality writing area.
- the inclined surface of the three-dimensional display unit may be embossed. According to this configuration, since the entire inclined surface is shrunk on the inclined surface, the written portion can be visually recognized three-dimensionally.
- the inclined surface of the three-dimensional display unit may be formed into a mirror surface whose surface roughness is smaller than that of the back surface of the display panel. According to this configuration, since the mirror surface is formed on the inclined surface, the brilliance of the inclined surface is emphasized, and the inclined surface is strongly illuminated, and the written portion can be visually recognized three-dimensionally.
- the inclination angle of the inclined surface with respect to the plane direction of the display plate on which the three-dimensional display unit is formed may be in the range of 40 degrees to 50 degrees. According to this configuration, since the inclination angle of the inclined surface with respect to the plane direction is formed in the range of 40 degrees to 50 degrees, the illumination light is well reflected by the inclined surface to increase the brilliance and improve the appearance. Can.
