  Hereinafter, the speedometer 3 will be described in detail.

  As shown in FIG. 2, the dial 2 is provided with a through hole 33 through which a shaft 34 a of a movement 34 described later is inserted, and behind the dial 2 (on the lower side indicated by the arrow in FIG. 2), The reflector 6, the light guide part 32, the movement 34, the light emitting diodes 37 and 38, and the printed board 7 are arranged. The printed circuit board 7 forms an electric circuit part of the combination meter 1, and the movement 34 and the light emitting diodes 37 and 38 are mounted on the printed circuit board 7.

  The movement 34 is composed of, for example, a cross coil actuator or a stepping motor, and rotates the shaft 34a by an angle corresponding to an external electric signal (vehicle speed signal in the present embodiment). The shaft 34a extends through the through hole 33 of the dial 2 to the front side, that is, the upper side indicated by the arrow in FIG. 2, and a pointer 35 is fixed to the tip thereof.

  The reflector 6 functions to guide, for example, white light from the light emitting diode 37 to the pointer 35, and the pointer 35 is formed so as to be lit and displayed in red, for example, by the light guided to the reflector 6. .

  A light shielding cap 36 is attached to the pointer 35. The light shielding cap 36 is made of, for example, a light shielding resin or metal, and prevents light from the light emitting diode 37 from directly entering the eyes of the driver.

  The light guide part 32 guides, for example, white light from the light emitting diode 38 as a light source to the dial 2 including the first decoration part 31. With this guided light, the first decorating unit 31 is configured so that the characters 3a and the scale 3b (FIG. 1) are lit and displayed in white, for example. .

  In this case, when the light emitting diode 38 is turned off, the dial 2 is displayed with white characters 3a and scales 3b by white light such as sunlight, and the background portions of the characters 3a and scales 3b are displayed in blue, for example. Configured as follows.

In addition, the light guide unit 32 guides light from the light emitting diode 38 to the first decoration unit 31 of the dial 2 and illuminates it.

  In the 1st decoration part 31, as shown in FIG. 3, the 1st light-diffusion layer 31f and the semi-translucent layer 31a are the front surfaces of the dial base material 31e which are board | plate materials, such as transparent polycarbonate resin (FIG. 3). The second light diffusion layer 31g and the opaque layer 31b are formed on the back surface of the dial base material 31e (the lower side indicated by the arrow in FIG. 3). As described above, these are formed by printing or hot stamping.

  The first light diffusion layer 31f diffuses the light when sunlight or the like enters from the upper side indicated by the arrow in FIG. 3 so that the driver does not feel glare. When the light from the light emitting diode 38 is incident from the lower side indicated by the arrow in FIG. 3, the second light diffusion layer 31 g diffuses the light to uniformly transmit and illuminate the first decorative portion 31. . The light diffusion layers 31f and 31g are formed of a material obtained by mixing non-translucent particles in a translucent resin, for example.

  The opaque layer 31b is formed of, for example, a black resin material that does not transmit light, and the opaque layer 31b is provided with an opening 31c in which the opaque layer 31b is not formed. As shown in FIG. 1, the opening 31 c corresponds to an extended scale 31 d that extends from the scale 3 b in the first decorative portion 31. The extension scale 31d, which is an indicator portion, is used for decoration that makes the speedometer 3 look larger.

  The semi-transparent layer 31a has a so-called half mirror characteristic, and has both a property of transmitting light and a property of reflecting light. The semi-translucent layer 31a is formed by printing or the like using, for example, a material in which a predetermined amount of aluminum powder having a predetermined particle size or shape is mixed in a translucent resin.

  In addition, the 1st decorating part 31 is comprised so that the extended scale 31d may be light-emitting-displayed white, for example, when the white light of the light emitting diode 38 permeate | transmits the 1st decorating part 31.

  On the other hand, unlike the speedometer 3, the tachometer 4 and the fuel / water temperature meter 5 are indicators 41a that are indicators for notifying the operating state of the equipment provided in the automobile, instead of the extension scale 31d, as shown in FIG. 53a and warnings 41a and 53a (hereinafter referred to as indicators / warnings 41a and 53a) that are indicators for warning the abnormality of the automobile are provided in the second decoration part 41 and the third decoration part 53.

  Each white arrow in the indicators / warnings 41a and 53a is a turn signal indicator that informs the driver of blinking of a blinker (not shown) of the vehicle.

  Moreover, the 2nd decorating part 41 and the 3rd decorating part 53 are also formed as shown in FIG.

  In the tachometer 4, unlike the speedometer 3, in FIG. 2, a light emitting diode 42 as a light source is provided corresponding to each indicator / warning 41a. Although not shown, the reflector 6 is formed so that the light of the light emitting diode 42 corresponding to each indicator / warning 41a does not transmit and illuminate the indicator / warning 41a adjacent to the indicator / warning 41a.

  In addition, the 2nd decorating part 41 is comprised so that each indicator / warning 41a may be light-emitted and displayed, for example by carrying out the illumination of the red light of the light emitting diode 42, for example.

  Further, the light-emitting diode 43 that transmits and illuminates the dial 2 is provided without providing the light guide portion 32, and the reflector 6 is formed in accordance with this. For example, white light from the light emitting diode 44 is guided to the pointer 45 and is configured to emit and display in red, for example. Although not shown, these points are the same for the fuel gauge / water temperature gauge 5.

  The tachometer 4 and the fuel gauge / water temperature gauge 5 are the same as the speedometer 3 in other points, and a description thereof will be omitted.

  The electric circuit configuration of the combination meter 1 according to the present embodiment described above will be described with reference to FIG.

  The control device 8 composed of a microcomputer or the like is always supplied with power from the battery 10, and the ignition switch 9 is connected so as to be able to detect its operation position (off position, on position) to detect the traveling speed of the vehicle. A vehicle speed sensor 11 and a sensor or switch (not shown) are connected to be able to input these signals.

  In addition, a light control switch 12 is connected to the control device 8 so as to be able to detect its operation position (off position, small lamp position, head lamp position). In the off position, all the vehicle width light, tail light and headlight are turned off. In the small lamp position, only the vehicle width light and tail light are turned on. In the on position, all the vehicle width light, tail light and headlight are turned on.

  Further, the movement 34 driven by the control device 8 according to the detection signal from the vehicle speed sensor 11, the movements (not shown) of the tachometer 4 and the fuel gauge / water temperature gauge 5, and the light emitting diodes 37, 38, 42, 43, Each light emitting diode (not shown) of 44 and the fuel gauge / water temperature gauge 5 is also connected to the control device 8.

(Operation)
The operation of the combination meter 1 configured as described above according to an embodiment of the present invention will be described.

  When the ignition switch 9 is turned on, in FIG. 5, the control device 8 detects it and starts operation. That is, based on the output signal from the speed sensor 10, the vehicle speed of the vehicle is calculated, and the movement 34 is driven so that the shaft 34a is rotated by an angle corresponding to the calculated vehicle speed.

  When the surroundings of the vehicle are bright, such as in the daytime, the light control switch 12 is operated in an off-position, and the vehicle width lamp, tail lamp, and headlamp are all turned off. With this off-position, the control device 8 turns off the light emitting diodes 37, 38, 43 and the light emitting diodes (not shown) of the tachometer 4 and the fuel gauge / water temperature gauge 5.

  On the other hand, when the surroundings of the vehicle are dark, such as at sunset, the light control switch 12 is operated to the small lamp position, and only the vehicle width lamp and the tail lamp are turned on. When the surroundings of the vehicle are dark, such as at night, the light control switch 12 is operated to the headlamp position, and the vehicle width lamp, tail lamp, and headlamp are all turned on.

  At these small lamp position and head lamp position, the control device 8 lights up the light emitting diodes 37, 38, 43 and the light emitting diodes (not shown) of the tachometer 4 and the fuel gauge / water temperature gauge 5.

  It should be noted that when the ignition switch 9 is turned on, a self-light-emitting meter that turns on each of these light emitting diodes may be used. However, in the case where each of these light emitting diodes is turned on with the small lamp position and the head lamp position, Explained.

  However, with respect to the light emitting diode 42 that displays the indicator / warning 41a and the light emitting diode (not shown) that displays the indicator / warning 53a, the control device 8 notifies the operating state of the equipment provided in the vehicle or an abnormality related to the vehicle. When notifying the contents, the corresponding light emitting diode is turned on.

Hereinafter, the visual recognition state of the speedometer 3, the tachometer 4, the fuel meter / water temperature meter 5, and the decorating units 31, 41, and 53 that decorate them respectively will be described for each operation position of the light control switch 12.
(1) Off position In the 1st decoration part 31, although the sunlight from the upper side which the arrow of FIG. 3 shows follows the optical path of the arrow P, it permeate | transmits the 1st light-diffusion layer 31f, but is reflected by the semi-transparent layer 31a. Is done. Thereby, the 1st decoration part 31 is silver-displayed by the front in FIG.

  Here, since the semi-transparent layer 31a has a half mirror characteristic, a part of light such as sunlight from the upper side indicated by the arrow in FIG. 3 is transmitted through the semi-transparent layer 31a. In order to reflect on the light transmissive layer 31b and pass through the semi transmissive layer 31a again, it is necessary to transmit the semi transmissive layer 31a twice. For this reason, compared with the intensity of the reflected light by the optical path of the arrow P, the intensity of the reflected light by the opaque layer 31b can be ignored.

  Further, due to sunlight, the characters 3a and scales 3b of the dial 2 are displayed in white in FIG. 1, and these background portions are displayed in blue. Thereby, the 1st decorating part 31 decorates the speedometer 3 displayed in white and blue by the silver display by the semi-translucent layer 31a. That is, the 1st decoration part 31 which is a decoration part displays silver different from the blue of a background part in the whole region.

  On the other hand, similarly to the case of the 1st decoration part 31, the decoration parts 41 and 53 also display silver in the whole region in FIG.

  Thereby, the decorating parts 41 and 53 decorate the tachometer 4 and the fuel gauge / water temperature gauge 5 which are display parts by the semi-transparent layer 31a, respectively. That is, the decoration parts 41 and 53 which are decoration parts respectively display the silver color different from the blue of a background part in the whole region.

Further, when notifying the operating state of the equipment provided in the automobile or notifying the abnormality content relating to the automobile, the corresponding indicator / warning 41a, 53a is turned silver by turning on the corresponding light emitting diode. The displayed decorations 41 and 53 are lit and displayed in red.
(2) Small lamp position and head lamp position As shown in FIG. 2, the white light of the light-emitting diode 37 that has been lit is guided by the reflector 6 to the pointer 35 along the optical path indicated by the arrow Q, and the pointer 35 emits red light. Display.

  On the other hand, a part of the lit white light of the light-emitting diode 38 is guided to the first decorating unit 31 by the light guide unit 32 along the optical path indicated by the arrow Q, and the first decorating unit 31 is transmitted and illuminated. The remaining part is reflected by the diffuse reflection layer 32a and is guided to the dial 2 according to the optical path indicated by the arrow to transmit and illuminate it.

  As shown in FIG. 3, the light of the light emitting diode 38 guided to the first decorating unit 31 follows the optical path indicated by the arrow Q in the opening 31 c where the opaque layer 31 b is not formed. The dial base material 31e, the semi-transparent layer 31a, and the first light diffusion layer 31f are transmitted in this order.

  However, the light of the light emitting diode 38 guided to the first decorative portion 31 cannot pass through the region where the opaque layer 31b is formed.

  Thereby, the extension scale 31d of the first decorative portion 31 corresponding to the opening portion 31c in which the opaque layer 31b is not formed is displayed in white in FIG. 1, and the remaining portion of the first decorative portion 31 is It becomes black (dark state). The pointer 35 is lit and displayed in red, the characters on the dial 2 and the scale 3b are lit and displayed in white, and the background portion of the dial 2 is black (dark state). As a result, the extension scale 31d of the first decoration unit 31 can make the speedometer 3 look larger.

  That is, the first decoration part 31 that is a decoration part emits and displays an extended scale 31d that extends from the scale 3b of the speedometer 3 that is a display part through the opening 31c of the opaque layer 31b. .

  On the other hand, in the decorating units 41 and 53, when notifying the operating state of the equipment provided in the automobile or notifying the abnormality content relating to the automobile, the corresponding indicator / lighting is turned on by turning on the corresponding light emitting diode. The warnings 41a and 53a are displayed in red in the black (dark state) decorating parts 41 and 53.

  In the combination meter 1 according to the embodiment of the present invention described above, when the light emitting diodes 38 and 42 serving as the light sources and the light emitting diodes (not shown) are turned off, the entire areas of the decorating units 31, 41 and 53 are displayed on the display units 3, 4, and 4. 5 is displayed in a color different from the color of the background portion of the character 3a and the scale 3b.

  Thereby, the decoration function as the original decoration part 31,41,53 can be exhibited in the state which does not display the extended scale 31d and the indicator / warning 41a, 53a in the decoration part 31,41,53.

  Each of the decorative portions 31, 41, 53 includes a semi-transparent layer 31a and a non-translucent layer 31b behind the semi-transparent layer 31a. The non-transparent layer 31b includes an extension scale 31d as an indicator portion and an indicator / An opening 31c having the shapes of warnings 41a and 53a is provided. For this reason, the decoration parts 31, 41, and 53 can display the extended scale 31d and the indicator / warnings 41a and 53a when the light emitting diodes 38 and 42 and the light emitting diode (not shown) are turned on.

  That is, the decorating units 31, 41, and 53 exhibit the decorating function sufficiently, while effectively utilizing the space of the decorating units 31, 41, and 53, and the extended scale 31d and indicators / Warnings 41a and 53a can be displayed as necessary.

  Further, since the decorating units 31, 41, 53 are arranged on the front side (the upper side of the paper surface of FIG. 1) from the display units 3, 4, 5, the display by the decorating units 31, 41, 53 and the display unit 3 , 4, and 5 can provide a three-dimensional effect and realize a more attractive and innovative display.

  Instead of the semi-translucent layer 31a, a translucent layer 31h may be used as shown in FIG. The translucent layer 31h has a property of transmitting light and has, for example, gray different from the blue color of the background portions of the characters 3a and the scale 3b. That is, the translucent layer 31h has lower light transmissivity than the colorless and transparent layer. The decorative display layer constituted by the first light diffusion layer 31f and the light transmissive layer 31h has a property of transmitting light and has a display color different from the blue color of the background portion of the characters 3a and the scale 3b. Therefore, the combination of the colors of the first light diffusion layer 31f and the light transmissive layer 31h is not limited to the case described above.

  In this case, when the light emitting diode 38 is turned off, the sunlight from the upper side indicated by the arrow in FIG. 4 passes through the first light diffusion layer 31f, but passes through the gray light transmissive layer 31h and is opaque. The intensity of light reaching the layer 31b is smaller than that of the colorless and transparent layer. Furthermore, in order for this transmitted light to be reflected by the opaque layer 31b and to pass through the transparent layer 31h again, it is necessary to transmit the transparent layer 31h twice.

  For this reason, the intensity of the light transmitted through the light transmitting layer 31h, reflected by the non-light transmitting layer 31b, and further transmitted through the light transmitting layer 31h is negligible, and the first decorative portion 31 is displayed in gray on the entire surface. Is done.

  When the light-emitting diode 38 is turned on, the light passes through the light-transmitting layer 31h and the like according to the optical path indicated by the arrow Q. However, when the light-emitting diode 38 is turned on and other parts are the same as those described above. Therefore, the description is omitted.

  The semi-transparent layer 31a (or the translucent layer 31h) is formed on the dial 2, but a decorative ring (not shown) is provided separately from the dial 2, and the semi-transparent layer 31a is provided on the decorative ring. You may form in. In this case, the decorative ring on which the semi-translucent layer 31a is formed is fixed to the dial 2 by hooking or welding.

  Also, contrary to the case described above, the indicators / warnings 41a and 53a are formed on the first decorative portion 31 and the extension scale 31d is formed on the second decorative portion 41 and the second decorative portion 53. good.

  Further, the control device 8 may be configured such that all the light emitting diodes 37, 38, 42, and 43 are turned on at the same time or turned on at the same time as the ignition switch 9 is turned on, and then turned off at the same time. good.

  Further, the control device 8 may be configured to include control means for interlocking the light emission display of the extension scale 31d with the rotation of the pointer 35.

  For example, the pointer 35 indicates 50 km / h in FIG. 1. At this time, the control device 8 performs control so that the extension scale 31d below this is displayed in a light emitting manner and the extension scale 31d beyond this is not displayed in a light emitting manner. To do. Thereby, the rotation of the pointer 35 can be more easily seen.

  In this case, unlike the above-described case, in FIG. 2, the light guide unit 32 is not provided, but a light emitting diode (not shown) that is a light source that transmits and illuminates the first decoration unit 31 is newly provided, and The dial 2 is used only for transmitted illumination.

  Specifically, a light-emitting diode (not shown) that illuminates and transmits the first decorative portion 31 is provided in correspondence with each extended scale 31 d, similarly to the second decorative portion 41. Although not shown, the reflector 6 is formed so that light of a light emitting diode (not shown) corresponding to each extension scale 31d does not transmit and illuminate the extension scale 31d adjacent to the extension scale 31d.

  Although a speedometer, a tachometer, and a fuel / water temperature meter are formed as the pointer meters, the present invention is not limited to these, and other meters such as a voltmeter may be replaced or added.
