(Operation)
Below, the operation | movement of the combination meter 1 by this embodiment is demonstrated in the said structure.

  When the ignition switch 13 is turned on by the driver, in FIG. 4, the control device 9 detects this and starts operation, turns on the light emitting diodes 61 and 62, and drives the movement 41. That is, the control device 9 calculates the vehicle speed of the vehicle based on the output signal from the speed sensor 10 and drives the movement 41 so as to rotate the shaft 42 by an angle corresponding to the calculated vehicle speed.

  Further, when the surroundings become dark (when the amount of external light incident on the combination meter 1 decreases), the driver turns on the small lamp lighting switch 12 to turn on the small lamp of the vehicle. The control device 9 detects this and turns on the light emitting diode 63.

  On the other hand, the control device 9 drives the liquid crystal display 5 to display the distance meter based on the detection signal from the speed sensor 10 and display the door indicator based on the detection signal of the door sensor 11.

  Hereinafter, the visual state of the speedometer (the dial 2, the translucent ring 3, and the pointer 4) will be described separately when the light emitting diode 63 is turned on and off.

(1) When the light-emitting diode 63 is extinguished The white light emitted from the light-emitting diode 61 is guided into the pointer 4 by the case 7 according to the optical path P1 in FIG.

  The white light emitted from the light emitting diode 62 is guided from the light guide portion 36 into the translucent ring 3 by the case 7 according to the optical path P2 in FIG. 3A, and the complementary scale formed on the first projecting portion 31. Reflected by the portion 34 toward the viewing side. This white reflected light is visually observed as the complementary scale portion 34 shown in FIG.

  The background portion 23 formed on the second protruding portion 21 of the dial 2 arranged behind the first protruding portion 31 is visually seen through the first protruding portion 31 as a background of the complementary scale portion 34 in a metallic style. . In addition, the blue character portion 22 formed on the upper surface of the background portion 23 is also viewed through the first protrusion 31 with the metallic background portion 23 as the background.

  The scale portion 32 of the first protrusion 31 is viewed as a metallic background portion 23 that is visible from the opening of the black print layer 33.

  Since the 1st protrusion part 31 and the 2nd protrusion part 21 protrude in the visual side (upper side in a figure) as shown in FIG.2 and FIG.3, the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 is arranged on the viewing side. Thereby, these three-dimensional effects can be emphasized more.

  Further, since the second projecting portion 21 is arranged behind the first projecting portion 31, the background contrast by the background portion 23 and the contrast of the character portion 22 are added behind the complementary scale portion 34. Thereby, the three-dimensional effect of the complementary scale part 34 can be emphasized more.

  Further, the embossed surface 35 is formed in a gradation so as to gradually become lighter toward the viewing side (upper side in FIG. 3), that is, from the center of rotation of the pointer 4 to the outer peripheral side in FIG. Therefore, the protruding state of the first protruding portion 31 can be more emphasized as a shadow. Thereby, the stereoscopic effect of the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 can be further emphasized.

(2) When the light-emitting diode 63 is turned on The white light of the turned-on light-emitting diode 61 causes the tip portion of the pointer 4 to emit light in red, and the white light of the turned-on light-emitting diode 62 is visually observed as the complementary scale portion 34. This is the same as when the light emitting diode 63 is extinguished.

  On the other hand, the white light emitted from the light-emitting diode 63 is transmitted through the background portion 23 in accordance with the optical paths P31 and 32 in FIG. 3A, and the background portion 23 is hardly visible. For this reason, the complementary scale part 34 is visually observed with the feeling that the illumination light from the light emitting diode 63 floats, and the scale part 32 is visually observed as white transmitted light from the opening of the black print layer 33.

  Further, the white light of the light-emitting diode 63 turned on is transmitted through the blue character portion 22 having translucency, and the character portion 22 is lit and displayed in blue. The character portion 22 is visually recognized on the back side of the complementary scale portion 34 with a feeling of floating with the illumination light from the light emitting diode 63 as a background.

  The white light emitted from the light-emitting diode 63 passes through the background portion 23 and passes through the embossed surface 35 in accordance with the optical path P31 in FIG. Since the embossed surface 35 is formed in a gradation so that the gradation gradually decreases toward the viewing side, the intensity of transmitted light along the optical path P31 increases toward the viewing side. Thereby, the protrusion state of the 1st protrusion part 31 can be emphasized more as a shadow. Thereby, the stereoscopic effect of the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 can be further emphasized.

  As described above, when the light emitting diode 63 is turned on, the stereoscopic effect of the scale portion 32, the complementary scale portion 34, and the character portion 22 can be further emphasized in a visual state different from that when the light emitting diode 63 is turned off.

Since the embossed surface 35 is formed so as to gradually darken toward the viewing side, the intensity of the reflected light along the optical path P23 increases toward the viewing side. Thereby, the protrusion state of the 1st protrusion part 31 can be emphasized more as a shadow.

  The background part 23 formed on the second protrusion part 21 of the dial 2 arranged behind the first protrusion part 31 is blue as the background of the scale part 32 and the complementary scale part 34 through the first protrusion part 31. It is visually observed. The character part 22 is visually recognized as an opening of the background part 23.

  Since the 1st protrusion part 31 and the 2nd protrusion part 21 protrude in the visual side (upper side in a figure) as shown in FIG. 6 and FIG. 7, the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 is arranged on the viewing side. Thereby, these three-dimensional effects can be emphasized more.

  Further, since the second protrusion 21 is arranged behind the first protrusion 31, the background contrast by the background portion 23 and the character portion 22 are compared behind the scale portion 32 and the complementary scale portion 34. Join. Thereby, the three-dimensional effect of the scale part 32 and the complementary scale part 34 can be emphasized more.

  Furthermore, the embossed surface 35 is formed so as to gradually become brighter toward the viewing side (upper side in FIG. 8), that is, from the outer peripheral side to the rotation center side of the pointer 4 in FIG. The protruding state of the protruding portion 31 can be more emphasized as a shadow. Thereby, the stereoscopic effect of the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 can be further emphasized.

(2) When the light emitting diode 63 is turned on The white light of the light emitting diode 61 that is turned on causes the tip portion of the pointer 4 to emit light in red, and the white light of the light emitting diode 62 that is turned on is the scale portion 3 and the complementary scale portion. The point that the light-emitting diode 62 is visually recognized as 34 and the white light of the turned-on light-emitting diode 62 is visually recognized as a shadow by the embossed surface 35 are the same as when the light-emitting diode 63 is turned off.

  On the other hand, the white light emitted from the light-emitting diode 63 is transmitted through the character portion 22 which is the opening of the background portion 23 according to the optical path P3 in FIG. When the light emitting diode 63 is turned on, the background portion 23 is hardly visible because the surroundings are dark. For this reason, the scale part 32 and the complementary scale part 34 are visually observed with the feeling of floating against a dark state.

  As described above, when the light emitting diode 63 is turned on, the stereoscopic effect of the scale portion 32, the complementary scale portion 34, and the character portion 22 can be further emphasized in a visual state different from that when the light emitting diode 63 is turned off.

  FIG. 9 is a cross-sectional view showing a third modification of the combination meter 1 shown in FIG.

  FIG. 10 is an enlarged view of a portion X in FIG.

  In the third modified example, as shown in FIGS. 9 and 10, the dial 2 is abolished and the translucent ring 3 is also used as the dial. Along with this, the character portion 22 and the background portion 23 are formed on the back surface (the lower surface in FIG. 10) of the first protrusion 31 of the translucent ring 3, and the print layer 24 is formed on the first layer. It is formed on the outer peripheral side (left side in FIG. 10) from the protrusion 31.

  Hereinafter, the visual state of the speedometer (translucent ring 3) in the combination meter 1 according to this modification will be described separately when the light emitting diode 63 is turned on and off.

(1) When the light emitting diode 63 is extinguished The white light emitted from the light emitting diode 62 is guided from the light guide portion 36 into the translucent ring 3 by the case 7 according to the optical path P2 in FIG. Reflected to the viewing side (upper side in FIG. 10) by the complementary scale portion 34 formed on 31. This white reflected light is viewed as the complementary scale part 34.

  The background portion 23 formed on the back surface of the first protruding portion 31 is visually observed through the first protruding portion 31 as a background of the complementary scale portion 34 in a metallic style. The blue character portion 22 formed on the back surface of the first projecting portion 31 is also viewed through the first projecting portion 31 with the metallic background portion 23 as the background.

  The scale portion 32 of the first protrusion 31 is viewed as a metallic background portion 23 that is visible from the opening of the black print layer 33.

  Since the first protruding portion 31 protrudes to the viewing side (upper side in the figure) as shown in FIGS. 9 and 10, the scale portion 32, the complementary scale portion 34, the character portion 22 and the background portion 23 are more on the viewing side. Will be placed. Thereby, these three-dimensional effects can be emphasized more.

  Furthermore, since the embossed surface 35 is formed in a gradation shape so that the shading gradually decreases toward the viewing side (upper side in FIG. 10), the protruding state of the first protruding portion 31 can be more emphasized as a shadow. Thereby, the stereoscopic effect of the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 can be further emphasized.

(2) When the light-emitting diode 63 is turned on The white light of the light-emitting diode 62 that is turned on is visually recognized as the complementary scale portion 34 in the same manner as when the light-emitting diode 63 is turned off.

  On the other hand, the white light emitted from the light emitting diode 63 is transmitted through the background portion 23 in accordance with the optical paths P31 and 32 in FIG. 10, and the background portion 23 is hardly visible. For this reason, the complementary scale part 34 is visually observed with the feeling that the illumination light from the light emitting diode 63 floats, and the scale part 32 is visually observed as white transmitted light from the opening of the black print layer 33.

  Further, the white light of the light-emitting diode 63 turned on is transmitted through the blue character portion 22 having translucency, and the character portion 22 is lit and displayed in blue. For this reason, the character part 22 is also visually recognized with the feeling of floating with the illumination light from the light emitting diode 63 as a background.

  Further, the white light emitted from the light emitting diode 63 is transmitted through the background portion 23 and the embossed surface 35 in accordance with the optical path P31 in FIG. Since the embossed surface 35 is formed in a gradation so that the gradation gradually decreases toward the viewing side, the intensity of transmitted light along the optical path P31 increases toward the viewing side. Thereby, the protrusion state of the 1st protrusion part 31 can be emphasized more as a shadow. Thereby, the stereoscopic effect of the scale part 32, the complementary scale part 34, the character part 22, and the background part 23 can be further emphasized.

  As described above, when the light emitting diode 63 is turned on, the stereoscopic effect of the scale portion 32, the complementary scale portion 34, and the character portion 22 can be further emphasized in a visual state different from that when the light emitting diode 63 is turned off.

  The combination meter 1 which is the pointer instrument according to the present invention described above is a first light-transmissive member having the first projecting portion 31 and the complementary scale portion 34 which is a reflecting portion formed on the first projecting portion 31. A light-emitting ring 3, a light-emitting diode 62 that is a first light source that makes light incident on the light-transmitting ring 3, and a pointer 4 that rotates substantially along the viewing-side front surface of the light-transmitting ring 3. The first protruding portion 31 is formed such that the front side of the first protruding portion 31 on the viewing side and the rear side of the first protruding portion 31 protrude toward the viewing side, and the complementary scale portion 34 visually checks the light emitted from the light emitting diode 62 It is formed so as to be visually recognized as a complementary scale which is a display design by reflecting to the side.

  Thereby, since a reflection part will be arrange | positioned more at the visual recognition side, the three-dimensional effect of the display design by a reflection part can be emphasized more.

  Note that the present invention is not limited to the above-described example, and combinations thereof and other various modifications are conceivable.
