  2 is a cross-sectional view taken along line II-II in FIG.

  FIG. 3 is a circuit configuration diagram illustrating an electrical circuit configuration of the combination meter 1 shown in FIG.

  The combination meter 1 that is a display device is arranged in front of the driver's seat of the automobile and displays various vehicle information related to the automobile. As shown in FIG. 1, the combination meter 1 according to the present embodiment includes a tachometer 20 as second display means on the left side indicated by an arrow in the figure, and a fuel gauge / water temperature gauge 30 on the right side indicated by an arrow in the figure. , And a speedometer 10 as a first display means larger than these.

  The speedometer 10 displays the traveling speed of the automobile, and the tachometer 20 displays the engine speed of the automobile. The fuel gauge / water temperature gauge 30 includes a fuel gauge 31 that displays the amount of remaining fuel, and a water temperature gauge 32 that displays the cooling water temperature of the engine.

  The speedometer 10 includes a dial 11 that is a first dial and a pointer 12 that is a first pointer that rotates along the front surface (the left surface indicated by the arrow in FIG. 2). The tachometer 20 includes a dial 21 that is a second dial and a pointer 22 that is a second pointer that rotates along the front surface thereof. The dials 11 and 21 are respectively formed with a character 11a and a scale 11b as first indexes and a character 21a and a scale 21b as second indexes.

  In FIG. 1, the dial plate 11 displays only the characters 11a and scales 11b indicated by solid lines without displaying the characters 21a and scales 21b indicated by broken lines. That is, the speedometer 10 displays the information on the traveling speed, which is the first information, by the dial 11 displaying the characters 11a and the scale 11b.

  In FIG. 1, the dial 21 shows a state in which only the characters 21 a and scales 21 b indicated by solid lines are displayed without displaying the characters 11 a and scales 11 b indicated by broken lines. That is, the tachometer 20 displays information on the engine speed, which is the second information, by the dial 21 displaying the characters 21a and the scales 21b.

  On the contrary, when the speedometer 10 displays the information on the engine speed by displaying the characters 21a and the scales 21b indicated by broken lines, the tachometer 20 has the characters 11a and the scales 11b indicated by broken lines. By displaying, information on the traveling speed is displayed. That is, the speedometer 10 and the tachometer 20 are configured to be able to exchange information displayed on each other.

  Hereinafter, the configuration of the speedometer 10 will be described in detail.

  The dial 11 is made of a light-transmitting material, for example, a dial base material 11c made of a white smoke-like (ground glass) resin plate having translucency. On the front surface of the dial base material 11c (the left surface shown by the arrow in FIG. 2), the background portions of the characters 11a and 21a and the scales 11b and 21b are matted, for example, in a white opaque state (or matte A background layer 11d having a low translucency) is formed by printing or hot stamping. The background layer 11d may be formed on the back surface of the dial base material 24 (the right surface shown by the arrow in FIG. 2).

  The characters 11a and 21a and the scales 11b and 21b are provided in a white smoke-like and translucent state as openings in which the background layer 11d is not formed.

  Alternatively, a white and non-transparent background layer 11d is formed on the colorless and transparent dial base material 11c, and a white smoke-like translucent display layer is formed in the opening where the background layer 11d is not formed. Thus, the characters 11a and 21a and the scales 11b and 21b may be formed.

  As shown in FIG. 2, the dial 11 is provided with a through-hole through which a shaft 13 a of a movement 13 to be described later is inserted. A reflector 14 is provided behind the dial 11 (on the right side indicated by the arrow in FIG. 2). A movement 13, for example, light emitting diodes 15a and 15b, which are first light sources that emit blue light, and a printed circuit board 16 are disposed. The printed circuit board 16 forms an electric circuit part of the combination meter 1, and the movement 13 and the light emitting diodes 15 a and 15 b are mounted on the printed circuit board 16.

  The movement 13 is composed of, for example, a cross coil actuator or a stepping motor, and rotates the shaft 13a by an angle corresponding to an electric signal from the outside (vehicle speed signal in the present embodiment). The shaft 13 extends through the through hole of the dial 11 to the front side, that is, the left side indicated by the arrow in FIG. 2, and the pointer 12 is fixed to the tip thereof.

  The reflector 14 guides the blue light from the light emitting diode 15a to the characters 11a and the scale 11b as the first index, and the blue light from the light emitting diode 15b to the characters 21a and the scale 21b as the second index of the dial 21. It leads to. FIG. 2 shows a state in which the light emitting diode 15a is turned on and the light emitting diode 15b is turned off.

  In addition, as shown in FIG. 1, the character 11a, the character 21a, the scale 11b, and the scale 21b are mutually adjacent | abutted. For this reason, the reflector 14 is configured such that the blue light from the light emitting diode 15a that transmits and illuminates the characters 11a and the scale 11b does not transmit and illuminate the adjacent characters 21a and the scale 21b.

  On the contrary, the reflector 14 is also configured so that the blue light from the light emitting diode 15b that transmits and illuminates the characters 21a and the scales 21b does not transmit the adjacent characters 11a and the scales 11b.

  A control device 44 (FIG. 3) composed of a microcomputer or the like is mounted on the printed circuit board 16. The control device 44 controls the movement 13, the light emitting diodes 15a, 15b, and the like in accordance with an external electric signal inputted.

  Since the configuration of the tachometer 20 is the same as the configuration of the speedometer 10, the description thereof is omitted.

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

  Electric power is always supplied from the battery 49 to the control device 44, and an ignition switch 48 is connected so as to be able to detect its operation position (off position, on position), a vehicle speed sensor 45 for detecting the vehicle speed of the vehicle, A rotation sensor 46 for detecting the engine speed, a changeover switch 47 for switching the display of the speedometer 10 and the tachometer 20, and a sensor or switch (not shown) are connected so that these signals can be input.

  The changeover switch 47 does not need to be newly provided, and can be used as a trip changeover switch or the like that switches between the cumulative travel distance display (odometer) of the vehicle and the section distance display (trip meter) of the vehicle. .

  In addition, devices driven by the control device 44 in accordance with output signals from these various sensors 45 and 46 and the switch 47 are connected. That is, the movement 13, the light emitting diodes 15a and 15b, and the like are connected to the control device 44.

  The speedometer 10, the tachometer 20, and the fuel / water temperature meter 30 described above are housed and held in an instrument housing unit including a design plate 41, a case 42, and a transparent cover 43 as shown in FIG. 2. ing.

  The operation of the combination meter 1 configured as described above according to the first embodiment of the present invention will be described.

  When the ignition switch 48 is turned on, in FIG. 3, the control device 44 detects it and starts operation. The control device 44 controls the light emitting diodes 15a and 15b to be turned on / off according to the switching operation of the changeover switch 47. In FIG. 2, the light emitting diode 15a is turned on and the light emitting diode 15b is turned off. That is, the speedometer 10 displays the information on the traveling speed by displaying the characters 11a and scales 11b shown by solid lines in FIG.

  At this time, the control device 44 calculates the vehicle speed of the vehicle based on the output signal from the speed sensor 45, and drives the movement 13 so as to rotate the shaft 13a by an angle corresponding thereto.

  As shown in FIG. 2, the blue light emitted from the light-emitting diode 15a is reflected by the reflector 14 in accordance with the optical paths indicated by the arrows P1 and P2, respectively, and the characters 11a and scales 11b (each opening of the background layer 11d) of the dial 11 Are transmitted and illuminated to emit blue light. However, since the reflector 14 prevents the blue light from the light emitting diode 15a from transmitting and illuminating the character 21a and the scale 21b, they do not emit light.

  Thereby, in the speedometer 10 shown in FIG. 1, the character 11a and the scale 11b are light-emitted and displayed in blue with white as a background, and the character 21a and the scale 21b are displayed in a white smoke tone. That is, the characters 11a and the scales 11b are displayed, but the characters 21a and the scales 21b, which are almost indistinguishable from the white background, are not displayed.

  As a result, the speedometer 10 displays the travel speed information by the dial 11 displaying the characters 11a and the scale 11b and the pointer 12 being controlled based on the output signal from the speed sensor 45.

  On the other hand, in the same manner, the tachometer 20 displays information on the engine speed by the dial 21 displaying the characters 21a and the scale 21b and the pointer 22 being controlled based on the output signal from the rotation sensor 46. To do.

  Here, for example, when the driver wants to view the information on the engine speed larger than the information on the traveling speed when driving on a circuit course or suddenly starting, the changeover switch 47 is switched. Accordingly, the control device 44 turns off the light emitting diode 15a and turns on the light emitting diode 15b. Further, based on the output signal from the rotation sensor 46, the number of revolutions of the engine is calculated, and the movement 13 is driven so that the shaft 13a is rotated by an angle corresponding thereto.

  In FIG. 2, the blue light from the light-emitting diode 15 b that has been lit is transmitted through and illuminated the characters 21 a and the scales 21 b (each opening of the background layer 11 c) of the dial 21 by the reflector 14, and these are emitted in blue. However, since the reflector 14 prevents the blue light from the light emitting diode 15b from transmitting and illuminating the characters 11a and the scale 11b, they do not emit light.

  Thereby, in the speedometer 10 shown in FIG. 1, with the white background, the characters 21a and the scales 21b are lit and displayed in blue, and the characters 11a and the scales 11b are displayed in white smoke. That is, the characters 21a and the scales 21b are displayed, but the characters 11a and the scales 11b, which are almost indistinguishable from the white background, are not displayed.

  As a result, the speedometer 10 displays the information on the engine speed by the dial 11 displaying the characters 21a and the scale 21b and the pointer 12 being controlled based on the output signal from the rotation sensor 46.

  On the other hand, in the same manner, the tachometer 20 displays the information on the traveling speed by the dial 21 displaying the characters 11a and the scale 11b and the pointer 22 being controlled based on the output signal from the speed sensor 45. .

  As a result, the driver performs a switching operation of the changeover switch 47, so that the person who wants to see the information on the traveling speed and the information on the engine speed is enlarged at a position that is easier to see (in FIG. Position and its size).

  The combination meter 1, which is the display device according to the first embodiment of the present invention described above, displays the first information by switching between the traveling speed information as the first information and the engine speed information as the second information. , And a tachometer 20 as second display means for switching and displaying information on traveling speed and information on engine speed. When the speedometer 10 displays one of travel speed information and engine speed information, the tachometer 20 displays the other of travel speed information and engine speed information.

  Thereby, it is possible to provide the combination meter 1 that allows the user to see the information he / she wants to see in a more easily viewable state (for example, in a state where the information can be seen at a more easily visible position).

  Furthermore, it is possible to realize a display that gives the viewer a sense of wonder, surprise, and enjoyment.

(Second Embodiment)
FIG. 4 is a front view of a combination meter 1 which is a display device according to the second embodiment of the present invention.

  5 is a cross-sectional view taken along line VV in FIG.

  6 is a cross-sectional view taken along line VI-VI in FIG.

  In the combination meter 1 which is a display device according to the second embodiment of the present invention, as shown in FIGS. 4 and 5, unlike the first embodiment, the movable dial 17 which is the first movable dial and the second movable character. A movable dial 27, which is a dial, is provided so that the outer periphery of the dial 11 as a first fixed dial and the dial 21 as a second fixed dial can be rotated.

  Each of the movable dials 17 and 27 is formed with a portion excluding “km / h” in the first character 11 a and a portion excluding “× 1000 rpm” in the second character 21 a. However, the scales 11b and 21b are not formed. On the other hand, the dials 11 and 21 are respectively formed with “km / h” and “× 1000 rpm” and a scale 11b among the characters 11a and 21a.

  In FIG. 4, the dial 11 and the movable dial 17 of the speedometer 10 display travel speed information, which is the first information indicated by a solid line, and the dial 21 and the movable dial 27 of the tachometer 20 are indicated by a solid line. The information of the engine speed which is the 2nd information to show is displayed.

  On the contrary, in the speedometer 10, when the movable dial 17 displays the information on the engine speed indicated by the broken line, the position of the character 21 a of the movable dial 17 and the scale 11 b of the dial 11 is shifted. Therefore, the movable dial 17 is rotated in the direction of the arrow A1 with respect to the dial 11 so that these positions are aligned.

  Similarly, in the tachometer 20, when the movable dial 27 displays the travel speed information indicated by the broken line, the positions of the characters 11a on the movable dial 27 and the scales 11b on the dial 21 are shifted. For this reason, the movable dial 27 is rotated with respect to the dial 21 in the direction of the arrow B1 so as to align these positions.

  Hereinafter, the configuration of the speedometer 10 will be described in detail.

  The movable dial 17 is composed of a light-transmitting material, for example, a dial base material 17a made of a white smoke-like resin plate having translucency. For example, a white non-transparent background layer 17b is formed on the front surface of the dial base material 17a (the left surface shown by the arrow in FIG. 5).

  The characters 11a and 21a are provided in a white smoke-like and translucent state as openings in which the background layer 17b is not formed. Alternatively, a white light-impermeable background layer 17b is formed on the colorless transparent dial base material 17a, and a white smoke-like translucent display layer is formed in the opening where the background layer 17b is not formed. May be.

  Since the dial 11 is formed in the same manner as in the first embodiment, this description is omitted.

  In FIG. 5, the dial 11 is fixed with respect to the reflector 14. The movable dial plate 17 is attached to the outer periphery of the dial plate 11 and behind it (the right side indicated by the arrow in the figure) so as to be sandwiched between the reflector 14 and the design plate 41 so as to be rotatable. It is done.

  Further, the light emitting diode 15b that transmits and illuminates the characters 21a and the scale 21b excluding “× 1000 rpm” is not provided. As described above, when the movable dial 17 displays the engine speed information indicated by the broken line, the movable dial 17 is adjusted so that the characters 21a of the movable dial 17 and the scale 11b of the dial 11 are aligned. The dial 11 is rotated in the direction of arrow A1. For this reason, the light emitting diode 15a can transmit and illuminate the character 21a of the rotated movable dial plate 17 and the scale 11b of the dial plate 11.

  The reflector 14 is configured not to transmit the adjacent character 21a when the light emitting diode 15a transmits the character 11a and the scale 11b. On the contrary, the reflector 14 is also configured not to transmit the adjacent character 11a when the light emitting diode 15a transmits the character 21a and the scale 11b.

  The first driving means for rotating the movable dial plate 17 with respect to the dial plate 11 is composed of a slide portion 19a, a permanent magnet 19b, a coil spring 19c and an electromagnetic solenoid 19d in FIG. The reflector 14 is formed with a guide groove 14a and a stopper 14b. The slide portion 19a can slide in the guide groove 14a in the arc-shaped directions of arrows A1 and A2 in FIGS. 4 and 5, and is restrained from sliding in the direction of the arrow A2 by the stopper 14b.

  Both ends of the coil spring 19 c are fixed to the reflector 14 and the slide portion 19 a, and the slide portion 19 a is fixed to the movable dial 17. The permanent magnet 19b is fixed to the slide portion 19a, and the electromagnetic solenoid 19d is fixed to the reflector 14. When a current flows through the electromagnetic solenoid 19d, the magnetic force acts from the electromagnetic solenoid 19d to the permanent magnet 19b.

  FIG. 6 shows a state in which no current flows through the electromagnetic solenoid 19d. That is, only the spring force of the coil spring 19c acts on the slide portion 19a in the direction of the arrow A2, and the slide portion 19a is restrained by the stopper 14b. This state corresponds to the state shown in FIG.

  Since the configuration of the tachometer 20 is the same as the configuration of the speedometer 10, the description thereof is omitted.

  The operation of the combination meter 1 configured as described above according to the second embodiment of the present invention will be described.

  When the ignition switch 48 is turned on, in FIG. 3, the control device 44 detects it and starts operation. The control device 44 controls the light emitting diodes 15a and 15b to be turned on / off according to the switching operation of the changeover switch 47. In FIG. 5, the light emitting diode 15a is turned on and the light emitting diode 15b is turned off. That is, the speedometer 10 displays the travel speed information by displaying the characters 11a and scales 11b indicated by solid lines in FIG.

  At this time, the control device 44 calculates the vehicle speed of the vehicle based on the output signal from the speed sensor 45, and drives the movement 13 so as to rotate the shaft 13a by an angle corresponding thereto.

  As shown in FIG. 5, the blue light emitted from the light-emitting diode 15a is reflected by the reflector 14 according to the optical path indicated by the arrows P1 and P2, and only the “km / h” of the characters 11a on the dial 11 and the scale 11b. (Each opening of the background layer 11d) and the character 11a (each opening of the background layer 17b excluding "km / h") of the movable dial 17 are transmitted and illuminated, and these are made to emit blue light.

  However, in the reflector 14, the blue light from the light emitting diode 15 a is only “× 1000 rpm” of the characters 21 a of the dial 11 and the characters 21 a of the movable dial 17 (each opening of the background layer 17 b except “× 1000 rpm”). These do not emit light in order to prevent transmission illumination.

  Thereby, in the speedometer 10 shown in FIG. 4, with the white background, the characters 11a and the scale 11b are lit and displayed in blue, and the characters 21a are displayed in white smoke. That is, the character 11a and the scale 11b are displayed, but the character 21a, which is almost indistinguishable from the white background, is not displayed.

  As a result, the speedometer 10 displays the characters 11a and the scale 11b, and displays the travel speed information by controlling the pointer 12 based on the output signal from the speed sensor 45.

  On the other hand, in the same manner, the tachometer 20 displays the character 21a and the scale 11b, and displays the information on the engine speed by controlling the pointer 22 based on the output signal from the rotation sensor 46.

  As described above, when it is desired to view the information on the engine speed larger than the travel speed information, the changeover switch 47 is switched. Thereby, the control device 44 turns off only the light emitting diode 15a that transmits and transmits only “km / h” of the characters 11a, and turns on the light emitting diode 15b that transmits and transmits only “× 1000 rpm” of the characters 21a. .

  Further, the control device 44 causes a current to flow through the electromagnetic solenoid 19d and causes a magnetic force to act on the permanent magnet 19b from the electromagnetic solenoid 19d. As a result, in FIG. 6, the permanent magnet 19b is attracted to the electromagnetic solenoid 19d, and the slide portion 19a slides in the guide groove 14a of the reflector 14 in the direction of the arrow A1. For this reason, in FIG. 4, the movable dial 17 rotates in the direction of arrow A <b> 1 with respect to the dial 11 so that the positions of the character 21 a of the movable dial 17 and the scale 11 b of the dial 11 are aligned.

  As a result, the blue light from the light-emitting diode 15a is turned on by the reflector 14 in FIG. 5 according to the optical path indicated by the arrow P1, and the scale 11b (each opening of the background layer 11d) of the dial 11 and the movable dial, respectively. Seventeen letters 21a (each opening of the background layer 17b, excluding “× 1000 rpm”) are transmitted and illuminated so that they emit blue light.

  Further, the blue light from the light emitting diode 15b that has been lit illuminates and transmits only “× 1000 rpm” of the characters 21a of the dial 11.

  As a result, the speedometer 10 displays the character 21a and the scale 11b, and displays the information on the engine speed by controlling the pointer 12 based on the output signal from the rotation sensor 46.

  On the other hand, similarly, the tachometer 20 displays the character 11a and the scale 11b, and displays the information on the traveling speed by the pointer 22 being controlled based on the output signal from the speed sensor 45.

  That is, even in the configuration according to the second embodiment, it is possible to provide the combination meter 1 that allows viewing of information that is desired to be viewed more easily (for example, in a state where the information can be viewed at a more easily visible position).

  Furthermore, since the movable dials 17 and 27 rotate with respect to the dials 11 and 21, respectively, it is possible to realize a display that gives the viewer more mystery, surprise, and enjoyment.

(Third embodiment)
FIG. 7 is a front view of a combination meter 1 which is a display device according to the third embodiment of the present invention.

  8 is a cross-sectional view taken along line VIII-VIII in FIG.

  As shown in FIGS. 7 and 8, the combination meter 1 that is a display device according to the third embodiment of the present invention includes a light shielding plate 18 that is a first light shielding plate and a second light shielding plate, unlike the second embodiment. A light shielding plate 28 is provided in place of the movable dials 17 and 27.

  Scales 11b are formed on the light shielding plates 18 and 28, respectively, and characters 11a and 21a are formed on the dial plates 11 and 21, respectively. The light shielding plate 18 is formed with an opening 18c that is a first opening, and the light shielding plate 28 is formed with an opening 28c that is a second opening. The characters 11a and 21a of the dial plates 11 and 21 are configured to be visible only through the openings 18c and 28c of the light shielding plates 18 and 28, respectively.

  In FIG. 7, the speedometer 10 displays travel speed information that is first information indicated by a solid line, and the tachometer 20 displays engine speed information that is second information indicated by a solid line.

  On the contrary, the speedometer 10 rotates the light shielding plate 18 in the direction of the arrow A1 with respect to the dial 11 when displaying the information of the engine speed indicated by the broken line. Thereby, the character 21 a of the dial 11 indicated by a broken line is visually recognized through the opening 18 c of the light shielding plate 18.

  Similarly, the tachometer 20 also rotates the light shielding plate 28 in the direction of the arrow B1 with respect to the dial 21 when displaying the traveling speed information indicated by the broken line. Thereby, the character 11 a of the dial 21 indicated by a broken line is visually recognized through the opening 28 c of the light shielding plate 28.

  Hereinafter, the configuration of the speedometer 10 will be described in detail.

  The dial 11 is formed in the same manner as in the above-described embodiment, and the light shielding plate 18 is formed of a light shielding plate base material 18a similar to the dial base material 17a of the movable dial 17 and a black light shielding layer 18b, for example. . That is, the scale 11b of the light shielding plate 18 is provided as an opening in which the light shielding layer 18b is not formed.

  In FIG. 8, the light-shielding plate 18 is the front surface of the dial 11 (the surface on the left side indicated by the arrow in the drawing) and is sandwiched between the dial 11 and the design plate 41 on the outer periphery thereof. Can be pivoted. The first driving means for rotating the light shielding plate 18 with respect to the dial plate 11 is the same as that in the second embodiment, and the description thereof is omitted.

  In addition, since the characters 11a and 21a are visually recognized through the opening 18c of the light shielding plate 18, for example, when the characters 11a are visually recognized, it is not necessary to configure the adjacent 21a so as not to transmit light.

  That is, the characters 11a, 21a and scale 11b excluding “km / h” and “× 1000 rpm” are always transmitted and illuminated, and the characters 11a, 21a to be displayed are visually recognized through the opening 18c of the light shielding plate 18. Thereby, the speedometer 10 can switch and display the information on traveling speed and the information on engine speed.

  As with the speedometer 10, the tachometer 20 can also switch and display information on traveling speed and information on engine speed.

  That is, even in the configuration according to the third embodiment, it is possible to provide the combination meter 1 in which information that is desired to be seen can be seen in a more easily viewable state (for example, in a state where the information can be seen at a more easily visible position).

  Furthermore, since the black light-shielding plates 18 and 28 rotate with respect to the dial plates 11 and 21, respectively, it is possible to realize a display that gives the viewer more mystery, surprise, and enjoyment. Moreover, it functions also as a decorative ring in which the black light shielding plates 18 and 28 rotate, and the appearance can be improved.

  In the above-described example, manual operation is performed by the changeover switch 47. However, for example, it may be configured to automatically switch according to a value of a speedometer or a tachometer.

  Further, the present invention is not limited to switching between the speedometer 10 and the tachometer 20, but can be applied to switching display between the fuel gauge 31, the water temperature gauge 32, and others.

  The display device according to the present invention includes first display means for switching and displaying the first information and the second information, and second display means for switching and displaying the first information and the second information. Furthermore, when the first display means displays one of the first information and the second information, the second display means displays the other of the first information and the second information. As long as this feature is satisfied, the present invention is not limited to the above-described example, and various other modifications can be considered.

  For example, the present invention is not limited to the pointer instrument, but can be applied to other display devices such as a liquid crystal display device and display devices other than those for vehicles.
