  The pointer 3 is formed of a translucent material such as an acrylic resin, and is lit and displayed by light emitted from the light emitting diode 5a mounted on the printed board 6. Further, on the printed circuit board 6, a control device 8 (FIG. 13) is mounted for controlling the turning on / off of both the light emitting diodes 5a, 5b and the driving control of the movement 4. The control device 8 is composed of, for example, a microcomputer.

  The dial 2, the printed board 6 and the like described above are accommodated and held in a case composed of the upper case 21 and the lower case 22.

  A design plate 23 that covers the end of the dial 2 is attached to the front side of the dial 2 (left side in FIG. 2), and a transparent cover 24 is attached to the tip of the design plate 23. The design plate 23 is made of, for example, a resin material, and the transparent cover 24 is made of a transparent resin thin plate or glass.

  The upper case 21 and the lower case 22 are molded from a resin material, and the upper case 21 has a function as a reflector, guides light from the light emitting diode 5a to the pointer 3, and transmits light from the light emitting diode 5b to the dial 2. Lead.

  On the other hand, the distance meter B indicating the cumulative travel distance and the section travel distance as information and the door indicator C indicating the door open / close state as information are formed as images on the liquid crystal panel 11 as display means. The

  The liquid crystal panel 11 is disposed on the rotation center side of the pointer 3 and on the front side (left side in FIG. 2) of the pointer instrument, that is, the center side of the speedometer A and the viewer side (left side in FIG. 2) in the viewing direction. ). As a result, the liquid crystal panel 11 is arranged so as to overlap with the speedometer A which is a pointer instrument in the visual recognition direction (left and right direction in FIG. 2). The liquid crystal panel 11 is electrically connected to the printed circuit board 6 through a multi-wire flexible lead wire 11a.

  The procedure for assembling the display unit 10 including the liquid crystal panel 11 and the like is as follows. The printed board 13, the reflection plate 15 a, the light guide plate 14, the diffusion plate 15 b and the liquid crystal panel 11 are stacked in this order and inserted into the casing 16.

  Thereafter, the transparent plate 15c is mounted in the facing plate 18, and the cover 17 is attached to the liquid crystal panel 11 from the left side in FIG. 3 so that the facing plate 18 is in close contact with the liquid crystal panel 11 in FIG. It fixes to the casing 16 by the hook mentioned later so that it may hold down to the right direction. In this way, the assembly of the display unit 10 is completed without using screws.

  The casing 16 includes two boss portions 16a in which screw holes 16b are formed (see FIG. 10B). As shown in FIG. 2, the boss portions are inserted by tightening the screws 7 into the screw holes 16b. 16 a is fixed to the upper case 21. That is, the display unit 10 is fixed to the upper case 21. At this time, the printed circuit board 6 is also fixed to the upper case 21 at the same time.

  Hereinafter, a fixing structure for the casing 16 such as the liquid crystal panel 11 which is a feature of the present invention will be described.

  As shown in FIG. 4, the liquid crystal panel 11 has a substantially disk shape, and cut surfaces 11b and 11c constituting the first positioning means are formed on both upper and lower sides in the drawing. The potting portion 11d is formed by applying a soft resin material that protects the connection portion between the liquid crystal panel 11 and the lead wire 11a.

  Behind the liquid crystal panel 11 (on the right side in FIG. 3), a light emitting diode 12 that is a light source that illuminates the liquid crystal panel 11, a printed circuit board 13 that is an electrical wiring board on which the light emitting diode 12 is mounted, and a light emitting diode 12 A light guide plate 14 is disposed as light guide means for guiding emitted light to the back surface (right side surface in FIG. 2) of the liquid crystal panel 11. The liquid crystal panel 11, the printed board 13, and the light guide plate 14 are accommodated and held in the casing 16.

  As shown in FIG. 5, the printed board 13 has a substantially rectangular shape, and cutout portions 13 a are formed at both upper ends in the drawing. Six light emitting diodes 12 and terminals 13b are mounted on the printed circuit board 13, and a multi-wire flexible lead wire 13c electrically connects the light emitting diodes 12 and the printed circuit board 6 through the terminals 13b.

  The light guide plate 14 is formed of a transparent acrylic resin or the like, and a textured surface 14g having minute irregularities is formed on the back surface (the right side surface in FIG. 3 and the lower surface in FIG. 6B). . The embossed surface 14 g reflects light from the light emitting diode 12 incident on the light guide plate 14 to the back surface of the liquid crystal panel 11.

  As shown in FIG. 6A, the light guide plate 14 has a substantially square shape with four ends cut, and recesses (14b, 14e) are formed between both lower ends in the drawing. . The concave portion is provided with an incident surface 14b and a positioning surface 14e, and both sides of the concave portion constitute a protruding portion 14a. As shown in FIG. 6B, the protrusion 14a is provided with a second contact surface 14d, and in the drawing, a first contact surface 14c is provided below the second contact surface 14d. .

  The embossed surface 14g of the light guide plate 14 is inclined upward from the left side to the right side in the drawing. This is because the light emitted from the light emitting diode 12 incident on the incident surface 14b from the left side can be reflected to the upper side (the liquid crystal panel 11) by the embossed surface 14g. Note that two pins 14f constituting second positioning means for positioning the light guide plate 14 with respect to the casing 16 are formed on the textured surface 14g.

  A decorative member 18 having an opening 18a is disposed on the front side (left side in FIG. 3) of the liquid crystal panel 11, and a cover 17 having an opening 17a is fixed to the casing 16 from the left side in FIG. Both the cover 17 and the decorative member 18 are made of acrylonitrile / butadiene / styrene (ABS) resin or the like.

  The opening 18a has the shape shown in FIG. 1 and is smaller than the liquid crystal panel 11 as shown in FIG. 3, and the opening 17a has a shape larger than the opening 18a. Thereby, the images of the liquid crystal panel 11, that is, the distance meter B and the door indicator C are visually recognized inside the opening 18a as shown in FIG.

  As shown in FIG. 7, the decorative member 18 has a circular container shape, and a positioning portion 18b as third positioning means on the right side (the side in contact with the casing 16 in FIG. 3) in FIG. 7B. , 18d, and concave portions 18e, 18f constituting the fourth positioning means are formed on the left side in FIG. 7B. As shown in FIG. 7C, the positioning portion 18 b is formed in a character shape having a substantially “convex” cross section, and the positioning surface 18 c is in contact with the inner surface 16 k (FIG. 10) of the casing 16. .

  The convex portion of the positioning portion 18b and the positioning portion 18d are inserted into a concave portion of the casing 16 (not shown), and the positioning surface 18c contacts the inner surface 16k of the casing 16.

  Thereby, the decorative member 18 is substantially perpendicular to the casing 16 in the left-right direction in FIG. 3 (the direction in which the light guide plate 14 and the liquid crystal panel 11 are stacked and housed in the casing 16, that is, the stacking direction). And it can position in the rotation direction rotated about this lamination direction as a substantially central axis. That is, the decorative member 18 is positioned with respect to the casing 16 in the linear direction and the rotational direction within the surface of the decorative member 18.

  Between the cover 17 and the decorative member 18, a transparent plate 15 c that is a translucent plate that protects the liquid crystal panel 11 is disposed. The transparent plate 15c is formed of a transparent acrylic resin or the like, and a textured surface having minute irregularities is formed on the surface (the left surface in FIG. 3). The embossed surface prevents extraneous light such as sunlight from being reflected by the transparent plate 15c and making the liquid crystal panel 11 difficult to see.

  As shown in FIG. 8, the transparent plate 15c has a substantially disk shape, and is formed with convex portions 15d and 15e constituting the fourth positioning means. The transparent plate 15c is mounted on the decorative member 18 from the left side in FIG. 7B so that the convex portions 15d and 15e are inserted into the concave portions 18e and 18f of the decorative member 18, respectively.

  Thereby, the transparent plate 15c can be positioned with respect to the decorative member 18 in a plane direction substantially perpendicular to the left-right direction (lamination direction) in FIG. 3 and a rotation direction that rotates about the lamination direction as a substantially central axis. That is, the transparent plate 15 c is positioned with respect to the decorative member 18 in the linear direction and the rotational direction within the surface of the decorative member 18. The reason why the sizes of the convex portions 15d and 15e are different from each other is to prevent the transparent plate 15c from being assembled to the decorative member 18 in reverse. When the transparent plate 15c is formed by injection molding, the transparent gate 15c is preferably installed on the large side where the liquid crystal panel 11 formed by the opening 18a of the decorative member 18 does not display, that is, on the lower side in FIG. .

  This is because if the molding gate of the transparent plate 15c is installed in the vicinity of the display range of the liquid crystal panel 11, that is, the upper side of FIG. Therefore, when the driver visually recognizes using polarizing type sunglasses, the illumination part where the polarizing direction due to the flow direction of the polarizing type sunglasses and the transparent plate 15c substantially intersects with the liquid crystal panel 11 has a large amount of polarized components. This is because the light is blocked and looks like a shadow.

  As shown in FIG. 9, the cover 17 has a circular container shape, and is fixed to the casing 16 from the left side of FIG. 3 by a locking portion 17b and a claw portion 17d. As shown in FIG. 9C, the locking portion 17b is provided with a notch 17c so as to be easily elastically deformed in the vertical direction in FIG.

  In addition, between the light guide plate 14 and the casing 16, a reflection plate 15 a that reflects light from the light emitting diode 12 incident on the light guide plate 14 to the back surface of the liquid crystal panel 11 is disposed. The reflecting plate 15a is made of polycarbonate resin or the like and has a white color with high reflectivity. As a result, when the inner surface 16k of the casing 16 is formed of black or the like with low light reflection without processing such as white resin, gloss plating or painting, the reflecting plate 15a is effective for improving the illumination brightness.

  Between the light guide plate 14 and the liquid crystal panel 11, a diffusion plate 15 b that guides the reflected light from the light guide plate 14 to the back surface of the liquid crystal panel 11 is disposed. The diffusion plate 15b is made of polycarbonate resin or the like and is subjected to light diffusion processing.

  The casing 16 is made of ABS resin or the like. In addition to the boss portion 16a, the casing 16 includes a support portion 16c, a third elastic portion 16d, a positioning hole 16e constituting the second positioning means, a first elastic portion 16f, a first elastic portion, as shown in FIG. Claw portions 16g, 16h, 16i and a second elastic portion 16j constituting one positioning means are formed. The second elastic portion 16j is formed in a substantially arc shape in accordance with the shape of the circular casing 16, so that the second elastic portion 16j can be installed in a small width between the outer shape of the casing 16 and the opening 18a of the decorative member. .

  The positioning hole 16e is for inserting the pin 14f of the light guide plate 14 so that the light guide plate 14 has a surface direction substantially perpendicular to the horizontal direction (stacking direction) in FIG. Positioning can be performed in a rotational direction that rotates about the stacking direction as a substantially central axis. That is, the light guide plate 14 is positioned with respect to the casing 16 in the linear direction and the rotation direction in the plane of the light guide plate 14.

  The claw portions 16 g and 16 h abut on the cut surfaces 11 b and 11 c of the liquid crystal panel 11, and the claw portion 16 i abuts on the circular portion of the liquid crystal panel 11. Thereby, the liquid crystal panel 11 can be positioned with respect to the casing 16 in a plane direction substantially perpendicular to the left-right direction (stacking direction) in FIG. 3 and a rotation direction rotating about the stacking direction as a substantially central axis. That is, the liquid crystal panel 11 is positioned with respect to the casing 16 in the linear direction and the rotational direction in the plane of the liquid crystal panel 11.

As a result, the printed circuit board 13 is fixed to the casing 16 by being sandwiched between the light guide plate 14 that holds the printed board 13 downward in FIG. 12B and the third elastic portion 16d that holds the printed board 13 upward. As a result, the printed circuit board 13 can be positioned in the thickness direction without using screw fixing, and can be fixed to the casing 16 by pressing the backlash while positioning in the stacking direction.

  Note that the third elastic portion 16d is formed as a cantilever extending from the casing 16, as shown in FIGS. 10 (a) and 10 (b). The third elastic portion 16d extends from the casing 16 in the vertical direction in the figure in a plane substantially perpendicular to the stacking direction (in the plane of FIG. 10A and FIG. 10B), and then left and right in the figure. Extend in the direction. By bending the third elastic portion 16d in this way (or even by a curved shape), the length of the beam of the third elastic portion 16d can be secured in a small space, and the third elastic portion The design freedom of the 16d elastic force and the amount of deflection can be further ensured.

  The positioning surface 14e of the light guide plate 14 positions the printed circuit board 13 with respect to the casing 16 in a direction perpendicular to the stacking direction (left and right direction in FIG. 12B).

  As described above, in this embodiment, since the display unit 10 is assembled without using screws, the assembling work is simplified and the display space can be used effectively.

  In the present embodiment, as shown in FIG. 3, the printed circuit board 13 is disposed substantially perpendicular to the dial 2 (in the stacking direction), so that the space for fixing the printed circuit board 13 to the casing 16 is more compact. Thus, the display space can be used more effectively while obtaining the above-described effects.

Further, the door indicator C, that is, the liquid crystal panel 11 that forms the door indicator C as an image is arranged on the front side of the speedometer A, and the distance meter B, that is, the liquid crystal panel 11e that forms the distance meter B as an image is a tachometer. It is arranged on the front side of B.

  The liquid crystal panel 11 is formed as a liquid crystal panel that controls a plurality of dot segments in an XY matrix, whereas the liquid crystal panel 11e displays numbers by the “day” character type segment and English characters by the English character type segment. Is formed as a liquid crystal panel. Therefore, the liquid crystal panel 11e has a simpler wiring structure for the liquid crystal panel than the liquid crystal panel 11, so that the liquid crystal panel 11e is smaller than the liquid crystal panel 11 and has a different shape from the liquid crystal panel 11, as shown in FIG. It can be formed in a polygonal shape that is easy to process.

  A mark 16m representing the shape of the liquid crystal panels 11 and 11e accommodated in the casing 16 is formed on the casing 16. FIG. 16A shows the casing 16 that houses the liquid crystal panel 11e, and the mark 16m is formed in an octagon representing the shape of the liquid crystal panel 11e, and is formed so that it can be seen from both the left and right sides in FIG. Is done.

  Thereby, when the liquid crystal panels 11 and 11e are assembled to the casing 16, the mark 16m can be visually observed from the left side in FIG. Further, when the display unit 10 assembled to the casing 16 to which the liquid crystal panels 11 and 11e are assembled, that is, the cover 17, is assembled to the pointer meters A and B, the mark 16m is visually observed from the right side in FIG. be able to.

  As a result, the liquid crystal panels 11 and 11e having different shapes can be correctly assembled to the casing 16, and the casing 16 in which the liquid crystal panel 11 is assembled can be correctly assembled to the speedometer A. The casing 16 assembled with 11e can be correctly assembled to the tachometer B.

  As shown in FIGS. 16A and 17, the claw portion 16 i is formed in the casing 16 to form a gap 16 r, and the light shielding wall 16 p is disposed between the light guide plate 14 and the gap 16 r in the casing 16. Form. Thereby, the light emitted from the light emitting diode 12 is shielded by the light shielding wall 16p along the optical path P1 in FIG. 17B, and passes through the light guide plate 14 from the gap 16r to the outside of the casing 16 (right side in FIG. 17B). Leakage can be suppressed. As a result, it is possible to suppress the leakage light from the gap 16r from being reflected on the dial 2, thereby suppressing the appearance of the combination meter 1 from being deteriorated.

  Moreover, as shown to Fig.18 (a), the light-guide plate 14 is provided with the recessed part 14h in which the light shielding wall 16p fits, and is formed in the shape along the light shielding wall 16p.

  Further, the reflection plate 15a and the diffusion plate 15b are also provided with recesses 15g and 15i into which the light shielding wall 16p is fitted, and are formed in a shape along the light shielding wall 16p. That is, the light shielding wall 16p is disposed between the reflecting plate 15a and the gap 16r and between the diffusing plate 15b and the gap 16r. The reflecting plate 15a and the diffusing plate 15b are located in front of the light shielding wall 16p (on the left side in FIG. 17B). ).

  For this reason, it can suppress that the light which the light emitting diode 12 emitted is guide | induced to the clearance gap 16r of the casing 16 through the light-guide plate 14 through the reflecting plate 15a and the diffusion plate 15b. As a result, it is possible to suppress the leakage light from the gap 16r from being reflected on the dial plate 2, thereby suppressing the appearance of the combination meter 1 from being deteriorated.

  Further, the reflection plate 15a is configured to be fixed by pressing the reflection plate 15a to the light guide plate 14, and the diffusion plate 15b is configured to be fixed by pressing the diffusion plate 15b to the casing 16. Specifically, the press-fitting hole 15h is formed in the reflection plate 15a, and the reflection plate 15a is pressed by pressing the pin 14f of the light guide plate 14 into the press-fitting hole 15h, that is, pressing the reflection plate 15a to the light guide plate 14. Fix to the light guide plate 14.

The diffusion plate 15 b is fixed to the casing 16 by pressing the plate 15 b against the casing 16. Further, since the light guide plate 14 is fixed to the casing 16, the reflection plate 15 a and the diffusion plate 15 b are fixed to the casing 16 without rattling. Thereby, generation | occurrence | production of the noise by the backlash with respect to the casing 16 of the reflecting plate 15a and the diffusion plate 15b can be suppressed.

  Further, in FIG. 16B, a textured surface 16n formed so that the pitch of minute irregularities is dense is formed by performing a light diffusion process on the surface of the casing 16 that faces the pointer 3. The pointer 3 receives and emits light emitted from the light emitting diode 5a, and this display light reaches the surface of the casing 16 facing the pointer 3 along the optical path P2. However, since this display light is diffused by the embossed surface 16n, the reflected light reflected from the dial 16 on the surface of the casing 16 that faces the pointer 3 is suppressed. Thereby, it can suppress that the appearance of the combination meter 1 falls.
