According to invention of Claim 1, the following effects can be acquired by the said structure. In other words, the enlarged display graphic part is a checkered pattern in which two types of rectangular parts of different colors are alternately arranged, so that it is separated from the dial body (in parallel) and enlarged. In this state, it is possible to obtain a sinking virtual image portion in which a checkered pattern can be visually recognized. Moreover, for each of the two square-shaped portion constituting a pattern of checkered pattern, as directionality is different for each color, by applying the stripes and horizontal stripes, for enlarged display of the checkered pattern The graphic part is not a simple checkerboard pattern, but can be shown as if a real woven cloth or a woven cloth similar to the real thing exists at a position away from the dial main body on the back side of the dial main body.
Further, only the central region of the dial main body can be viewed as a three-dimensional decoration as a sinking virtual image portion. In particular, since the central area is a part that is different in function from the numerical display area and the scale area, the most suitable part for applying a three-dimensional decoration by visual effects can be used effectively.

According to invention of Claim 2, the following effects can be acquired by the said structure. That is, at least a portion in the central region of the dial main body can be visually recognized as a three-dimensional decoration as a sinking virtual image portion. In particular, the center area is a function that is different from the numeric display area and scale area.
It is possible to effectively utilize the most suitable part for applying the three-dimensional decoration by the visual effect.

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

  1 to 6 show an embodiment of the present invention.

  <Configuration> First, the configuration will be described.

  A vehicle such as an automobile is provided with a resin instrument panel at the front of the vehicle interior. A vehicle display device 1 such as an instrument device as shown in FIG. 1 is provided on the driver's seat side of the instrument panel (also present in the center in the vehicle width direction). . Some of such vehicle display devices 1 are provided with a dial 2. This dial 2 has a dial main body 3 made of a transparent resin substrate.

  Then, as shown in FIG. 2, a fine lens layer 5 in which a large number of fine lenses 4 are arranged is provided on the surface of such a dial plate body 3. An enlarged display graphic portion 6 is provided on the back surface of the dial main body 3 so as to correspond to the fine lens layer 5. Then, due to the lens effect of the fine lens layer 5, as shown in FIG. 3, the magnified display graphic portion 6 can be visually recognized in a state of being separated from the dial main body 3 and enlarged in the back side. Part 7 is configured to be obtained.

  Further, in this embodiment, the following configuration is provided.

  (1) As shown in FIG. 4 (see also FIG. 5), the above-described enlarged display graphic part 6 is a checkered pattern in which two types of square-shaped parts 11 and 12 having different colors are arranged alternately. There are 13 symbols. As shown in FIG. 6, the vertical stripe pattern 14 and the horizontal stripe pattern 15 are different from each other in the direction of each of the two types of quadrangular portions 11 and 12 constituting the checkered pattern 13. And apply. As a result, the enlarged display graphic portion 6 of the checkered pattern 13 is present on the back side of the dial main body 3 at a position away from the dial main body 3, or the real woven fabric 16 or a woven fabric 16 that approximates the real thing exists. It is configured to be visible as if it were.

  (2) In the above description, as shown in FIG. 1, the dial main body 3 has at least a pointer shaft hole 21 and a pointer rotation region 22 that extends around the pointer shaft hole 21. The pointer turning area 22 includes a central area 23 located near the pointer shaft hole 21, a numerical display area 24 located on the outer peripheral side of the central area 23, and a scale area 25. And the sinking virtual image part 7 is provided in the part of the center area | region 23 at least.

  (3) The configuration other than the above is as disclosed in the drawings. The more specific configuration described above is as follows.

  The “fine lens 4” is basically a convex lens. The micro lens 4 is a so-called micro lens or the like. It is preferable that the microlenses 4 have the same size and shape. This fine lens 4 can be molded simultaneously and integrally with the dial main body 3 using a precision mold. Further, the fine lens 4 can be printed on the dial body 3 formed in advance. When the fine lens 4 is printed and formed, for example, an ink jet printer or the like is used to eject ink formed by dissolving a transparent resin with a solvent onto the surface of the dial main body 3. The injected transparent resin naturally becomes a convex lens shape due to surface tension.

  The “fine lens layer 5” is configured to function as a single convex lens as a whole when viewed macroscopically by the above-described many fine lenses 4. Needless to say, the “micro lens layer 5” functions as an aggregate of a large number of the micro lenses 4 described above when viewed microscopically. As described above, since the fine lens 4 is extremely small, it is not so much concerned that the fine lens layer 5 is provided for the dial main body 3. It should be noted that the arrangement of the microlenses 4 with respect to the surface of the dial main body 3 (arrangement, installation pattern, etc.) and the interval between the microlenses 4 are only required to obtain the above characteristics. For example, it is standard that the microlenses 4 are arranged in a matrix. The fine lens layer 5 has a lens effect that enlarges the object (in this case, the enlarged display graphic portion 6) from the same magnification to several tens of times. In particular, at the same magnification, the sinking virtual image portion 7 of the enlarged display graphic portion 6 is visually recognized so as to be present at the position of the dial main body 3, and becomes farther away from the dial main body 3 as the enlargement magnification increases. It will be visually recognized to exist. As described above, the microlens layer 5 is configured to have a function as a single convex lens as a whole when viewed macroscopically, and therefore, between the microlens 4 and the enlarged display graphic portion 6, No special correspondence is required (for example, as in the above-described conventional example, there is no need for one-to-one correspondence between the fine lens 4 and the graphic of the enlarged display graphic portion 6). Further, the fine lens layer 5 having a large number of fine lenses 4 causes the enlarged display graphic portion 6 to be displaced with respect to the surface direction of the dial main body 3 or rotationally displaced along the surface of the dial main body 3. By doing so, the lens effect (magnification, etc.) can be changed. Such characteristics are considered to be obtained when the curvature radius and focal length of the microlens 4 are extremely small. Such characteristics are considered to be obtained by the intersection angle between the arrangement of the microlenses 4 and the design of the enlarged display graphic portion 6. Therefore, the enlarged display graphic portion 6 is set and adjusted on the back surface of the dial main body 3 so as to obtain a required lens effect. In particular, when the enlarged display graphic portion 6 is a simple geometric pattern or the like, it is possible to intentionally generate interference fringes (moire) or the like depending on the enlargement magnification. .

  As described above, the “enlarged display graphic portion 6” is provided on the back surface of the dial body 3 corresponding to the fine lens layer 5. However, since the enlarged display graphic portion 6 is displayed in an enlarged manner, it is not always necessary to provide the enlarged display graphic portion 6 in the same range as the fine lens layer 5, and the enlarged display graphic portion 6 provides the necessary submerged virtual image portion 7. If so, it can be provided in a narrower range than the fine lens layer 5, or on the contrary, in a wider range. The enlarged display graphic portion 6 is printed on the back surface of the dial body 3. The enlarged display graphic portion 6 may be translucent or semi-translucent or non-translucent. However, in the case where at least the enlarged display graphic portion 6 is made translucent or translucent, an opaque mask layer 31 is formed at least on the back side of the enlarged display graphic portion 6. It is preferable to keep them. The opaque mask layer 31 can be printed. The opaque mask layer 31 is usually composed of a black print layer or the like. Even when the enlarged display graphic portion 6 is made opaque, it is needless to say that the same opaque mask layer 31 may be formed on the back side of the enlarged display graphic portion 6. is there.

  The “sinking virtual image portion 7” is an enlarged virtual image that appears to be sinking to the back side with respect to the dial body 3 literally. In this case, the sinking virtual image portion 7 is formed as if the three-dimensional decoration was given to the dial main body 3 (three-dimensional decoration).

  When the enlarged display graphic portion 6 is a “checkered pattern 13” pattern as described above, the two types of quadrangular portions 11 and 12 having different colors (color, brightness, etc.) are, for example, square. Is preferable. In this case, the size of the square-shaped portions 11 and 12 of the checkered pattern 13 as the original drawing is, for example, one having a side of about 1 mm or less as shown in FIG. And as shown in FIG. 5, the square-shaped parts 11 and 12 visually recognized as the sinking virtual image part 7 are expanded to a size of about 3 to 15 mm on one side, preferably about 5 to 10 mm on one side. The magnification is set and adjusted as follows. The colors used for the two types of quadrangular portions 11 and 12 are mainly white, black, and gray, but other colors and the like may be used. In this case, a combination of white and black is used.

  The “vertical stripe pattern 14” and “horizontal stripe pattern 15” applied to the two types of quadrangular portions 11 and 12 are preferably formed using the colors of the other party. The vertical stripe pattern 14 and the horizontal stripe pattern 15 may use other colors. The thickness and the number of stripes of the vertical stripe pattern 14 and the horizontal stripe pattern 15 are adjusted so as to be optimal according to the situation. In this case, as shown in FIG. 6, three black vertical lines are applied to the white rectangular portion 11 as the vertical stripe pattern 14, and three white stripes 15 are applied to the black rectangular portion 12 as the horizontal stripe pattern 15. By applying the horizontal line, the vertical stripe pattern 14 and the horizontal stripe pattern 15 are formed. The vertical lines and horizontal lines described above are substantially parallel to the corresponding sides of the quadrangular portions 11 and 12. Note that the number of vertical lines and horizontal lines described above is not limited to three each, and may be smaller or larger or different in number.

  It is preferable that the “real woven fabric 16” or “the woven fabric 16 similar to the real fabric” image a highly functional fiber fabric such as carbon fiber. It is preferable for the visual effect that the highly functional fiber cloth is slightly coarse. The above magnification is set in consideration of these points.

  On the other hand, in the case of the analog type vehicle display device 1, a pointer (not shown) is disposed on the surface side of the dial main body 3 in a state substantially parallel to the dial main body 3. The pointer is arranged so as to be rotatable along the dial main body 3. For this purpose, the base of the pointer is rotatably supported by the pointer shaft. The dial main body 3 is formed with a pointer shaft hole 21 through which the pointer shaft can be disposed in a direction perpendicular to the surface. The vehicle display device 1 having a pointer includes a speedometer, a tachometer, a fuel meter, a water temperature meter, and the like.

  The “pointer turning region 22” is preferably a circular shape with the pointer shaft hole 21 as the center. However, the pointer turning area 22 is not limited to a circle. For example, a partial circular shape in which a part (for example, the lower part) is cut out may be used. It should be noted that a single pointer turning region 22 or a plurality of pointer turning regions 22 can be formed for one dial main body 3. In this case, it is assumed that a single element is formed.

  The “central region 23” is provided in a portion of the pointer rotation region 22 through which the base portion and the intermediate portion of the pointer pass. On the other hand, the “numerical value display area 24” and the “scale area 25” are provided in the pointer rotation area 22 where the tip of the pointer passes and the outer periphery thereof. The central area 23 is a portion that is not necessary for reading the driving information with the pointer (non-displayed portion), whereas the numerical display area 24 and the scale area 25 are necessary for reading the driving information with the pointer. It has a functional difference that it is a part (present part). In order to obtain the most effective visibility, the scale area 25 is usually provided so as to be located on the outer peripheral side of the numerical value display area 24 separately from the numerical value display area 24. However, the scale area 25 may be provided together with the numerical value display area 24, or may be provided on the inner peripheral side of the numerical value display area 24. In the numerical value display area 24, a numerical value portion 32 and the like are formed, and in the scale area 25, a scale portion 33 is formed. In a normal case, the numerical display area 24 and the scale area 25 are provided with background portions 34 and 35 of the same color or different colors, respectively. The background portions 34 and 35, the numerical value portion 32, and the scale portion 33 of the numerical value display area 24 and the scale area 25 are printed on the front or back surface of the transparent dial body 3.

  Note that an edge portion 36 having a required width dimension may be provided outside the pointer rotation region 22.

  Further, the sinking virtual image portion 7 (the minute lens layer 5 and the enlarged display graphic portion 6 constituting the same) can also be provided for the numerical display area 24 and the scale area 25. In this case, the background portions 34 and 35 of the numerical display area 24 and the scale area 25 are not colored (that is, the background remains transparent) Only the numerical value portion 32 and the scale portion 33 are printed and formed so that the sinking virtual image portion 7 can be visually recognized from the outside. However, in the case where the sinking virtual image portion 7 is provided for the numerical display area 24 and the scale area 25, it is formed by applying the background portions 34 and 35 to the fine lens layer 5 of the numerical display area 24 or the scale area 25. It is structurally possible to hide the sinking virtual image portion 7 so that it cannot be visually recognized from the outside. As a result, it is possible to easily make the dial 2 having different specifications of the sinking virtual image portion 7.

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

  The above-mentioned dial main body 3 configured to obtain the submerged virtual image portion 7 by having the fine lens layer 5 on the front surface and the enlarged display graphic portion 6 on the back surface is provided on the vehicle display device 1. Install and install in the passenger compartment. Thereby, the sinking virtual image part 7 of the dial main body 3 is visually recognized as a stereoscopic image (3D image) having a sense of depth, and decorates the dial main body 3.

  According to this embodiment, the following operational effects can be obtained.

  (1) A fine lens layer 5 in which a large number of fine lenses 4 are arranged is provided on the surface of the dial main body 3 formed of a transparent substrate, and the rear surface of the dial main body 3 is made to correspond to the fine lens layer 5. The enlarged display graphic portion 6 is provided, and the enlarged display graphic portion 6 is separated from the dial main body 3 by the lens effect of the fine lens layer 5 and can be visually recognized in the enlarged state. In the dial structure configured to obtain the embedded virtual image portion 7, the enlarged display graphic portion 6 has a checkerboard pattern 13 formed by alternately arranging two types of quadrangular portions 11 and 12 having different colors and the like. At the same time, the vertical stripe pattern 14 and the horizontal stripe pattern 15 are applied to each of the two types of quadrangular portions 11 and 12 constituting the checkerboard pattern 13 so as to have different directions for each color, etc. Graphic part 6 for enlarged display of pattern 13 By configuring so that the real woven fabric 16 or the woven fabric 16 approximated to the real thing exists at a position away from the dial main body 3 on the back side of the dial main body 3, The following effects can be obtained.

  In other words, the enlarged display graphic portion 6 is formed as a checkerboard pattern 13 in which two types of rectangular portions 11 and 12 having different colors or the like are alternately arranged, so that the dial main body 3 is located on the back side (almost). In a state of being separated and enlarged in parallel), it is possible to obtain the sinking virtual image portion 7 in which the checkerboard pattern 13 can be visually recognized.

  Moreover, by applying the vertical stripe pattern 14 and the horizontal stripe pattern 15 to the two types of quadrangular portions 11 and 12 constituting the checkerboard pattern 13 so as to have different directions for each color, etc. The enlarged display graphic portion 6 of the pattern 13 is not a simple checkerboard pattern 13 but a real woven cloth 16 or a woven cloth approximated to the real thing at a position away from the dial main body 3 on the back side of the dial main body 3. 16 can be seen as if it exists.

  At this time, by making the color used for the two types of quadrangular portions 11 and 12 of the checkered pattern 13 have a large difference in brightness such as white and black, white expands due to the illusion, and black Since it appears to shrink, the feeling that warp yarn and weft yarn are woven up and down between the two types of quadrangular portions 11 and 12 can be obtained, thereby approximating the real woven fabric 16 or the real fabric. It is possible to make the woven fabric 16 appear more realistically in the back.

  Note that if the genuine woven fabric 16 is simply placed away from the back side of the dial body 3, it may become invisible like a stereoscopic image (3D image). It seems that there is room for elaboration in the arrangement and display of the woven fabric 16 of the fabric. As in this embodiment, the checkerboard pattern 13 having the vertical stripe pattern 14 and the horizontal stripe pattern 15 is used. When the real woven fabric 16 is expressed, a sense of reality can be produced (produced) relatively easily.

  Further, for example, when a real woven fabric 16 or the like is arranged on the back side of the dial main body 3, the thickness dimension around the dial main body 3 is increased, the material cost is increased, the device While various problems such as an overall configuration and a complicated manufacturing process occur, by using a checkered pattern 13 having a vertical stripe pattern 14 and a horizontal stripe pattern 15 as in this embodiment, The thickness around the dial body 3 and the material cost can be suppressed, and the configuration of the entire apparatus and the simplification of the manufacturing process can be achieved.

  (2) In the above, the dial main body 3 has at least the pointer shaft hole 21 and the pointer rotation region 22 that extends around the pointer shaft hole 21, and the pointer rotation region 22 is the pointer shaft hole. 21, a numerical area 24 located on the outer peripheral side of the central area 23, and a scale area 25, and the sinking virtual image portion 7 is at least in the central area 23. By providing for this, the following effects can be obtained.

  That is, at least a portion of at least the central region 23 of the dial main body 3 can be visually recognized as a sinking virtual image portion 7 as if a three-dimensional decoration was applied. In particular, since the central area 23 is a part having a different function from the numerical display area 24 and the scale area 25, the most suitable part for applying a three-dimensional decoration by visual effects can be used effectively. .

  Although the embodiments of the present invention have been described in detail with reference to the drawings, the embodiments are only examples of the present invention, and the present invention is not limited to the configurations of the embodiments. Needless to say, design changes and the like within a range not departing from the gist of the invention are included in the present invention.
