An enlarged design portion formed by enlargement is configured to be visible at a position away from the surface of the transparent substrate.

  However, when a three-dimensional display dial is used as the dial, there is a problem that it becomes difficult to incorporate the above-described dial illumination function unit and a lighting function unit such as a warning lamp with respect to the three-dimensional display dial. is there.

  In order to solve the above problems, the invention described in claim 1 is capable of lighting and displaying a dial, a dial illumination function unit capable of illuminating the dial, and a warning lamp display unit on the dial part. In an instrument display device equipped with a lighting function unit such as a warning light, the dial has a fine lens part on the surface side of the transparent base material and an enlarged display pattern part on the back side of the transparent base material. And a 3D display dial configured so that an enlarged design portion formed by enlarging the enlarged display design portion with a fine lens portion can be visually recognized at a position away from the surface of the transparent substrate. A thin light guide plate for illuminating a dial that has a functional part in contact with the back side of the 3D display dial, and a dial that can illuminate the 3D display dial via the thin light guide plate for illuminating the dial A light source for illumination, and the lighting function portion such as a warning light is a thin light for dial illumination. Provided with a warning light display plate disposed in contact with the back side of the light guide plate, and a warning light lighting light source capable of lighting and displaying the warning light display portion formed on the warning light display plate. It is characterized by.

  According to invention of Claim 1, the following effects can be acquired by the said structure. That is, the three-dimensional display dial plate can visually recognize an enlarged symbol part formed by enlarging the enlarged display symbol part with a fine lens part at a position away from the surface of the transparent substrate. By using such a three-dimensional display dial plate, it is possible to obtain an instrument display device having a high three-dimensional effect. In addition, by placing a thin light guide plate for dial illumination in contact with the back side of the three-dimensional display dial plate, the three-dimensional display dial plate can be directly illuminated together with the enlarged symbol portion by the dial plate illumination light source. . In addition, since the thin light guide plate for dial illumination is arranged in direct contact with the back side of the three-dimensional display dial plate, the three-dimensional display dial plate can be illuminated regardless of the display unit such as a warning light. Almost no influence is exerted on the display unit such as the lamp. In addition, by providing an independent warning light display board separately from the 3D display dial, the illumination for the 3D display dial and the function of the warning light display unit can be provided separately. And, by placing a display plate such as a warning light on the back side of the thin light guide plate for dial illumination, overlapping the thin light guide plate for dial illumination, the portion of the enlarged design portion of the three-dimensional display dial plate A warning lamp or the like can be lit up and displayed. At this time, by making the thin light guide plate for dial illumination thin, the display unit such as a warning lamp is present at a position close to the surface of the transparent base material, and can be clearly recognized without blur such as a contour. It becomes possible to do so. Therefore, it is possible to incorporate the dial illumination function unit and the lighting function unit such as a warning lamp in a well-balanced manner.

  An object of the present invention is to make it possible to incorporate a dial illumination function unit and a lighting function unit such as a warning lamp in a well-balanced manner when a stereoscopic display dial is used.

  Hereinafter, embodiments embodying the present invention will be described together with illustrated examples.

  1 to 9 show an embodiment of the present invention.

  <Configuration> First, the configuration will be described.

  An instrument display device 1 as shown in FIGS. 1 to 3 (mainly see FIG. 1) is attached to a vehicle interior such as an automobile at the front part of the passenger compartment. In this case, the instrument display device 1 is a dual meter provided integrally with two instrument parts 2 and 3 of a speedometer and a tachometer. However, the configuration of the instrument display device 1 is not limited to this.

  As shown in FIG. 2, the instrument display device 1 has a configuration in which an electronic substrate 5 and a dial 6 are attached to a resin housing (not shown). The dial 6 is arranged on the upper side (surface side) of the electronic substrate 5 in parallel with a required interval. In the case of the dual meter described above, the electronic board 5 and the dial 6 are shared by the two instrument parts 2 and 3 described above.

  A movement 8 is attached to the back side of the electronic substrate 5, and an output shaft 9 of the movement 8 is substantially in a straight surface with respect to shaft holes 11 and 12 formed in the electronic substrate 5 and the dial 6, respectively. It is arranged through. The output shaft 9 is used as a pointer shaft 13, and the base portion (or the vicinity thereof) of the pointer 14 is attached to the tip end of the pointer shaft 13 protruding to the surface side of the dial 6. Further, a pointer cap 15 is fitted to the attachment portion between the pointer shaft 13 and the pointer 14 so that the attachment portion can be hidden. The pointer 14 is formed of a colorless or colored transparent resin so that illumination is possible. On the other hand, the pointer cap 15 is formed of an opaque resin or the like in order to prevent the pointer illumination light from leaking outside.

  A pointer illumination function unit 16 is provided for such an instrument display device 1 so that the pointer 14 can be illuminated at night. As the pointer illumination function unit 16, one or a plurality of pointer illumination light sources 17 are attached to a position corresponding to the inner portion of the pointer cap 15 on the surface side of the electronic substrate 5. As the pointer illumination light source 17, a power-saving low-intensity (long-life) light source such as an LED is used. Around the pointer illumination light source 17, there is a substantially cylindrical pointer light leakage prevention wall having a height that reaches the dial 6 from the electronic substrate 5 so as to substantially correspond to the outer periphery of the pointer cap 15. 18 is provided.

  On the other hand, as shown in FIG. 4, the dial 6 includes a resin transparent base 21 and a dial design forming portion 22 formed on the back side of the transparent base 21.

  As shown in FIG. 1, the dial design forming portion 22 described above defines a pointer rotation area 25 and an external area 26 outside the pointer rotation area 25. Among these, the pointer turning area 25 is formed to indicate a range in which the pointer 14 is turned. In this case, the pointer rotation area 25 further includes a numerical scale display portion 27 that constitutes the outer peripheral portion and a central area portion 28 that constitutes the inner portion of the numerical scale display portion 27. The numerical scale display unit 27 is shaped like a band having a required width and is shaped like a ring. The numerical scale display unit 27 includes a strip-shaped painted portion 31 and a numerical value / scale unit 32. Further, the central region portion 28 is substantially circular. Note that the shape of the pointer rotation region 25 and the like is not limited to a circular shape, and may be, for example, a notched circular shape obtained by partially cutting a circular shape.

  As shown in FIGS. 2 and 3, the instrument display device 1 includes a dial illumination function unit 35 that can illuminate the dial 6 at night or the like. The dial illumination function unit 35 will be described later.

  In order to illuminate the numerical scale display unit 27 by the dial plate illumination function unit 35, the numerical value / scale unit 32 is a non-printing part or a colored translucent printing part. Further, the band-like painted portion 31 other than the numerical value / scale portion 32 is a dark-colored opaque printing portion.

  Further, the instrument display device 1 is provided with a lighting function unit 39 such as a warning light that can display a warning light display unit 38 on the dial 6 when necessary regardless of daytime or nighttime. The warning light lighting function unit 39 will be described later.

  Note that warning lights and the like include warning lights, instruction lights, indicator lights, and the like.

  In contrast to such a basic configuration, in this embodiment, the following configuration is provided.

  That is, as the dial 6 described above, as shown in FIG. 4, it has a fine lens portion 41 on the front surface side of the transparent base material 21 and an enlarged display design portion 42 on the back surface side of the transparent base material 21 (see FIG. 5). ), And an enlarged symbol portion 43 (see FIG. 6) formed by enlarging the enlarged display symbol portion 42 with the fine lens portion 41 is located away from the surface of the transparent substrate 21, as shown in FIG. A three-dimensional display dial 44 configured to be visually recognized is used.

  Further, as the dial illumination function unit 35, as shown in FIGS. 2 and 3, a thin dial light guide plate 45 for dial illumination arranged in contact with the back side of the three-dimensional display dial 44, and for dial illumination A dial illumination light source 46 capable of illuminating the three-dimensional display dial 44 via the thin light guide plate 45 is provided.

  As the warning lamp lighting function unit 39, a warning lamp display board 48 disposed in contact with the back side of the thin plate light guide plate 45, and a warning lamp display formed on the warning lamp display board 48 are displayed. A lighting light source 49 such as a warning lamp capable of lighting the unit 38 is provided.

  At this time, in order to improve the visibility, the lighting function unit 39 such as a warning light is arranged in a concentrated manner with respect to the central region portion 28 of the pointer rotation region 25. For this purpose, the warning lamp display plate 48 of the warning lamp lighting function unit 39 is provided so as to be overlapped (abuttingly disposed) on the back side of the dial light thin light guide plate 45 of the dial lighting function unit 35. To do.

  The above detailed configuration is as follows.

  First, as shown in FIG. 4, the “fine lens portion 41” is configured as, for example, a fine lens group installation portion having many so-called micro lenses 51. The microlens 51 can be formed on the transparent substrate 21 using, for example, a precision mold. In addition, the microlens 51 can be printed on the transparent substrate 21 by, for example, ejecting ink in which a transparent resin is dissolved in a solvent using an ink jet printer. In this case, the injected transparent resin naturally becomes a convex lens due to surface tension.

  Note that when the microlens portion 41 is an aggregate of convex lens-shaped microlenses 51 (microconvex lenses), roughly speaking, a lens effect close to that of a single convex lens can be obtained. However, the enlargement effect for the enlarged display symbol portion 42 is obtained only when the enlarged display symbol portion 42 has a specific positional relationship (in the plane direction of the three-dimensional display dial 44) with respect to the fine lens portion 41. It will be. This specific positional relationship has a slight range, and the magnification by the fine lens portion 41 can be changed within this range. At this time, as the magnification by the fine lens portion 41 increases, the enlarged symbol portion 43 of FIGS. 6 and 7 tends to appear far away.

  It should be noted that in most cases where the enlarged display pattern portion 42 deviates from the specific positional relationship described above with respect to the fine lens portion 41 (hereinafter referred to as a normal positional relationship), the enlargement effect cannot be obtained (that is, It can only be seen at the same magnification). As described above, the fine lens portion 41 has characteristics different from those of one convex lens.

  In this case, the enlarged symbol portion 43 is generated for the outer region 26 and the central region portion 28. The numerical scale display portion 27 is set so that the band-shaped painted portion 31 and the numerical value / scale portion 32 are visually recognized at the same magnification.

  Therefore, for example, the transparent lens 21 is provided with the fine lens portion 41 on almost the entire surface, and the numerical scale display portion 27 includes the band-shaped painted portion 31 and the numerical value / scale portion 32 with respect to the fine lens portion 41. The external display 26 and the central region 28 are arranged so that the enlarged display pattern portion 42 is located above the microlens portion 41 with respect to the fine lens portion 41. The specific positional relationship is formed.

  Alternatively, the microlens portion 41 and the enlarged display pattern portion 42 are partially provided only at positions corresponding to the outer region 26 and the central region portion 28 of the transparent base material 21 and are enlarged with respect to the microlens portion 41. The display symbol 42 may be in the specific positional relationship described above.

  The “enlarged display design portion 42” shown in FIG. 5 is composed of a translucent printing portion. The enlarged display symbol portion 42 may be any symbol as long as it is suitable as a symbol of the dial 6. However, since the enlarged display design portion 42 becomes the design of the dial 6, it is preferable that the display portion 42 has a color or tone that is not so conspicuous. In this case, for example, a light color checkered fine pattern is used. Further, a base color print layer 23 is formed on the back side of the enlarged display design portion 42. In this case, the base color printing layer 23 is preferably formed of mirror-based ink or the like having reflectivity with respect to light (external light) from the front surface side and transparency with respect to light (illumination light) from the back surface side. The mirror ink is dull silver or the like. The enlarged display design portion 42 and the base color print layer 23 are formed by, for example, screen printing or offset printing.

  The “enlarged symbol portion 43” shown in FIGS. 6 and 7 is obtained by partially enlarging the above-described enlarged display symbol portion 42 several tens of times. As described above, when the fine lens portion 41 has a lens effect close to that of a single convex lens, the enlarged symbol portion 43 is visually recognized behind the surface of the transparent substrate 21. (Subduction magnified virtual image).

  The “thin light guide plate 45 for dial illumination” shown in FIGS. 2 and 3 is made of a transparent resin. This thin light guide plate 45 for dial illumination is provided for a portion that performs dial illumination. In this case, dial illumination is performed in both the central region 28 of the pointer rotation region 25 and the external region 26. However, only the central area 28 of the pointer rotation area 25 provided with the lighting function section 39 such as a warning lamp is illustrated. The outer region 26 is not particularly illustrated, but a structure substantially similar to that of the central region 28 can be employed. In this case, the thin plate light guide plate 45 for dial illumination has a substantially circular shape having a size equal to that of the pointer turning region 25. The dial illumination thin light guide plate 45 is formed with a through hole having a size substantially corresponding to the inner periphery of the pointer illumination light leakage prevention wall 18 described above.

  The thin light guide plate 45 for dial illumination is preferably as thin as possible. In this case, a transparent film having a thickness of about 0.3 mm to 0.5 mm is used. On the back surface side of the thin plate light guide plate 45 for dial illumination, for example, as shown in FIGS. 8 and 9, a reflection portion 52 for reflecting light from the light source 46 for dial plate illumination toward the transparent substrate 21. Is formed. In this case, the size of the reflecting portion 52 is adjusted so that the light closer to the dial illumination light source 46 becomes smaller and the farther becomes larger so that the transparent substrate 21 can be illuminated uniformly. I do it.

  2 and 3, a power-saving low-intensity (long-life) light source such as an LED is used for the “dial plate light source 46”. The dial illuminating light source 46 is disposed, for example, in direct contact with the end face of the dial illuminating thin light guide plate 45. For example, as shown in FIG. 2, the dial illumination light source 46 is provided with one or several extension portions 53 on the peripheral portion of the thin dial light guide plate 45 for dial illumination, and is installed on the extension portion. Anyway. Alternatively, as shown in FIG. 3, the dial plate light source 46 may be provided at a plurality of locations on the peripheral portion of the thin plate light guide plate 45 with a gap in the circumferential direction. When the dial illumination light source 46 may interfere with the stereoscopic display dial 44, the dial illumination thin light guide plate 45 is provided with the dial illumination light source 46 to such an extent that interference does not occur. It is also possible to fold the portion to be bent to the opposite side so that there is no crease.

  As described above, the “warning lamp display plate 48” is provided independently of the three-dimensional display dial plate 44, and in this case, is installed in the central region portion 28 of the pointer rotation region 25. For this reason, the warning light display board 48 is formed in a disk shape having the same size as that of the central region 28. The warning light display board 48 is formed with a through hole having a size substantially corresponding to the inner periphery of the pointer illumination light leakage prevention wall 18 described above.

  As shown in FIG. 3, the warning lamp display board 48 includes a resin-made transparent base material 55 and a warning lamp design design portion 56 formed on the back surface side or the front surface side of the transparent base material 55. It is configured. The design design part 56 for warning lights and the like includes the above-described warning light display part 38 and an outer painted portion 57 other than the warning light display part 38.

  A plurality of “warning lamp display portions 38” are formed at predetermined intervals in the circumferential direction with respect to the perforated disc-shaped warning lamp display plate 48. The warning light display board 48 and the warning light display unit 38 are installed so as to have a positional relationship (normal positional relationship) in which the magnification effect by the fine lens unit 41 cannot be obtained. Therefore, the 3D display dial 44 is enlarged in the center region 28 to the position on the back side (from the 3D display dial 44) of the enlarged display symbol portion 42 that is actually located on the near side. In addition to being visually recognized as an enlarged symbol portion 43, the warning light display portion 38 that is actually located on the back side is displayed at the position of the three-dimensional display dial 44 (on the near side) at the time of lighting display. It will be visible at double. In addition, the warning light display unit 38 is visually recognized in a state where it overlaps the enlarged symbol unit 43.

  The warning light display unit 38 may be a non-printing unit or a colored translucent printing unit. Further, it is preferable that the outer painted portion 57 is an opaque transmission portion and has a color that is not so conspicuous so that it is difficult to see from the outside. The outer painted portion 57 is white for convenience in FIG. 3, but is not limited thereto.

  As the “lighting light source 49 such as a warning light”, a power-saving low-intensity (long-life) light source such as an LED is used. The light source 49 for lighting a warning light or the like is independently attached to a position corresponding to each warning light display portion 38 of the electronic board 5. As shown in FIG. 2, a warning light leakage prevention wall 59 having a height reaching the warning light display panel 48 from the electronic board 5 is provided around each light source 49 for lighting the warning light. The light leakage prevention walls 59 for warning lights and the like may be formed separately or integrally, and when they are integrated, they are further integrated with the light leakage prevention wall 18 for pointer illumination. You may make it comprise.

  <Operation> Next, the operation of this embodiment will be described.

  When the movement 8 is driven, the pointer 14 is rotated via the pointer shaft 13. Thus, the numerical value / scale portion 32 of the numerical scale display portion 27 can be displayed on the pointer 14.

  When the illumination is not lit during the daytime or the like, the numerical scale display portion 27 is visually recognized at the same position as the transparent base material 21 on the three-dimensional display dial 44. Further, an enlarged symbol portion 43 that is enlarged to a position on the back side of the transparent base material 21 is visually recognized in the central region portion 28 and the external region 26 of the pointer rotation region 25. As a result, the three-dimensional display dial 44 has a high three-dimensional effect having a difference in height (or a difference in position in the front-rear (depth) direction) between the numerical scale display unit 27 and the enlarged symbol unit 43. In this state, the warning light display unit 38 is not displayed.

  The pointer 14 can be illuminated by turning on the pointer illumination light source 17 at night or the like. Similarly, by lighting the dial illumination light source 46, the three-dimensional display dial 44 (at least the pointer turning area 25) can be illuminated via the dial illumination thin light guide plate 45. At this time, the pointer 14 is illuminated so that the pointer 14 is illuminated by the light from the pointer illumination light source 17 entering the pointer 14. In the numerical scale display unit 27, the light from the dial illumination light source 46 passes through the base color printing layer 23 and the numerical value / scale part 32, thereby illuminating the numerical value / scale part 32. Further, in the central area portion 28, the light from the dial illumination light source 46 passes through the base color print layer 23 and the enlarged display design portion 42, so that the enlarged design portion 43 appears to shine. In this state, the warning light display unit 38 is not displayed. Similarly, the enlarged pattern portion 43 can be illuminated with respect to the external region 26 as well.

  Then, when necessary, the warning light display unit 38 is turned on by illuminating the light source 49 for lighting, such as a warning light, at any time of the day or night, and the enlarged symbol 43 portion of the three-dimensional display dial 44 is displayed. In addition, the warning light display section 38 can actually be seen through. At this time, in the central region 28, the light from the lighting light source 49 such as a warning light is displayed on the warning light display portion 38 of the warning light display plate 48, the thin light guide plate 45 for dial illumination, and the three-dimensional display. By passing through the base color print layer 23 of the dial 44 and the enlarged display design portion 42, the warning light display portion 38 is illuminated. In this case, the warning lamp display unit 38 is visually recognized at the same magnification at the position of the three-dimensional display dial 44. Note that an enlarged display symbol portion 42 is superimposed on the warning light display portion 38. However, since the enlarged display symbol portion 42 is a light-colored fine pattern as described above, the enlarged display symbol portion 42 is displayed. The part 42 does not stand out. On the other hand, by turning off the light source 49 for turning on the warning light or the like, the warning light or the like display unit 38 is turned off so that it cannot be seen from the enlarged symbol portion 43 of the stereoscopic display dial 44. Note that the above is performed independently for each of the plurality of warning light display units 38.

According to this embodiment, the dial 6, the dial illumination function unit 35 that can illuminate the dial 6, and the warning lamp or the like that can display the warning lamp or the like display unit 38 on the dial 6 are turned on. In the instrument display device provided with the functional unit 39, the dial 6 has the fine lens portion 41 on the front surface side of the transparent base material 21 and the enlarged display design portion 42 on the back surface side of the transparent base material 21. Thus, a three-dimensional display dial 44 configured to be able to visually recognize an enlarged symbol portion 43 formed by enlarging the enlarged display symbol portion 42 with the fine lens portion 41 at a position away from the surface of the transparent substrate 21 is used. The dial illumination function unit 35 is a thin dial light guide plate 45 for dial illumination that is disposed in contact with the back surface side of the three-dimensional display dial 44, and the three-dimensional display dial plate via the thin light guide plate 45 for dial illumination. 44, and a light source 46 for illuminating a dial that can illuminate 44. The lamp lighting function unit 39 includes a warning lamp display plate 48 disposed in contact with the back side of the thin plate light guide plate 45 and a warning lamp display unit 38 formed on the warning lamp display plate 48. By providing the lighting light source 49 such as a warning light that can be turned on, the following effects can be obtained. Below are bulleted items.
The three-dimensional display dial 44 can visually recognize an enlarged symbol portion 43 formed by enlarging the enlarged display symbol portion 42 with the fine lens portion 41 at a position away from the surface of the transparent substrate 21.
-By using such a three-dimensional display dial 44, it is possible to obtain the instrument display device 1 having a high three-dimensional effect.
Further, by placing the dial illumination thin light guide plate 45 in contact with the back side of the 3D display dial 44, the 3D display dial 44 is directly illuminated by the dial illumination light source 46 together with the enlarged symbol portion 43. Will be able to.
In addition, since the dial illumination thin light guide plate 45 is directly in contact with the back side of the 3D display dial 44, the 3D display dial 44 is illuminated regardless of the warning light display unit 38. In addition, the warning lamp display unit 38 can be hardly affected.
Further, by providing an independent warning lamp display plate 48 separately from the three-dimensional display dial plate 44, the above-described illumination for the three-dimensional display dial plate 44 and the function of the warning lamp display unit 38 can be provided separately. It becomes possible.
And, by placing the warning light display plate 48 in contact with the back side of the thin light guide plate 45 for dial illumination so as to overlap the thin light guide plate 45 for dial illumination, The warning lamp display unit 38 can be turned on and displayed on the enlarged symbol portion 43.
At this time, the thin light guide plate 45 for illuminating the dial is made thin so that the display unit 38 such as a warning lamp is present at a position close to the surface of the transparent base material 21 and there is no blur such as a contour. It becomes possible to make it clearly visible.
Therefore, it is possible to incorporate the dial plate lighting function unit 35 and the lighting function unit 39 such as a warning lamp in a well-balanced manner.
