Description

  The present invention relates to an instrument device suitable for use in, for example, a vehicle fuel gauge, speedometer, engine tachometer, water temperature gauge, analog timepiece, and the like.

  FIG. 7 is a cross-sectional perspective view illustrating a conventional fuel gauge for a vehicle, and FIG. 8 is a cross-sectional view of the fuel gauge shown in FIG.

  Conventionally, in the fuel gauge 1 for a vehicle, as shown in FIGS. 7 and 8, the dial 7 and the design portion 8 are illuminated by reflecting the light emitted from the first light source 2 in the illumination chamber 5. The pointer 9 is illuminated by guiding the light emitted from the second light source 3. However, the fuel gauge 1 has a drawback that the three-dimensional effect is poor because the dial 7 and the design portion 8 are flatly displayed.

In view of this, there has been proposed a technique for expressing a three-dimensional effect by adopting a display plate in which planar ground color plates are arranged in parallel behind a planar transparent plate (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 10-149122

  However, in this case, the transparent plate and the ground color plate are only a combination of flat surfaces, and there is a problem that a high-class feeling is lacking.

  The same applies to instrument devices other than the fuel gauge 1 (for example, speedometer, engine tachometer, water temperature gauge, analog clock, etc.).

  An object of this invention is to provide the instrument device which can solve such a subject.

First, in the invention of the instrument device according to claim 1, a translucent display plate, a design portion provided on the surface of the display plate, and a translucent ground color plate disposed on the back surface of the display plate And a light source provided at the rear of the ground color plate, and the back surface of the display plate is provided with a concave portion that is partially different from the ground color plate.
In the invention of the instrument device according to claim 2, the concave portion is inclined so that the display plate becomes thinner toward the outside along the outer periphery of the display plate.
In the invention of the instrument device according to claim 3, the concave portion is inclined so that the display plate becomes thinner toward the center of the display plate.
The invention of the instrument device according to claim 4 is characterized in that the recess is provided with a texture.
Further, in the instrument device invention according to claim 5, a pointer is rotatably provided on the display plate, and the concave portion is provided with a plurality of concentric shapes centering on a rotation shaft portion of the pointer. It consists of a slit.

  ADVANTAGE OF THE INVENTION According to this invention, the instrument apparatus which can acquire not only a three-dimensional effect but a high-class feeling can be provided.

In addition, a design portion 17 is provided on the surface of the display board 15 by sticking, printing, engraving, molding, etc., and this design portion 17 is “F” indicating that the fuel is full (full). It has a shape that connects the scale, the scale of “E” indicating that the fuel is empty, and three scales that divide the scale into four equal parts. Further, a pointer 19 is rotatably attached to the center of the display plate 15 so as to be inserted into the rotary shaft 11a of the inner unit 11, and the pointer 19 is a needle-shaped instruction that indicates the remaining amount of fuel. A portion 19a and a cylindrical rotation shaft portion 19b that connects the instruction portion 19a to the rotation shaft 11a of the internal unit 11 are provided. Further, a look-back 21 is provided around the display board 15 so as to be positioned above the case 12. A conical recess 16 is formed on the back surface of the display plate 15 so as to be gradually inclined so that the display plate 15 becomes thinner along the outer periphery of the display plate 15.

  Since the vehicular fuel gauge 1 has the above-described configuration, light is emitted from the light source 14 as indicated by a one-dot chain line in FIG. Then, the light enters the light guide member 22 and is then guided to the light guide member 22 and reaches the display plate 15. As a result, the entire surface of the display plate 15 emits light, and the design portion 17 is lifted with respect to the case 12 and visually recognized in a hollow state. Therefore, a three-dimensional effect can be obtained.

  Further, a conical concave portion 16 is formed on the back surface of the display board 15, and the thickness, and consequently the luminance, of the display board 15 changes from the central part to the peripheral part. A feeling can be obtained.

May be made to emit light. In this way, if the color is changed from the cold color to the warm color, the color change becomes conspicuous and the warning effect can be enhanced. In this case, the warning lamp can be omitted in the meter layout, and space can be saved.

  In each of the above-described embodiments, the fuel gauge 1 has been described. However, the present invention may be applied to an instrument device other than the fuel gauge 1 (for example, a speedometer, an engine tachometer, a water temperature gauge, an analog clock, etc.). it can. At this time, by changing the emission color according to the type of the instrument device for a plurality of types of instrument devices, each instrument device may be easily identified by color.

  The present invention can be widely applied to various industrial fields such as automobiles, airplanes, trains, manufacturing plants, electrical appliances, and OA equipment.
