Description

  The present disclosure relates to a vehicle display device mounted on a vehicle.

  Conventionally, a vehicular display device mounted on a vehicle is known. The vehicle display device described in Patent Document 1 has a pointer and a dial. The pointer indicates the state of the vehicle by indicating an index. The dial is arranged on the back side of the pointer and forms indicators such as scales and letters, and light is projected from the back side by the light guide member in response to the movement of the pointer. The surface displays the tail of the light, which is a pattern display light, corresponding to the movement of the pointer, and produces an effect of movement of the pointer.

JP-A-5-248896

  However, as in Patent Document 1, only the pattern display light is displayed on the dial in response to the movement of the pointer, so that the glitter pattern is recognized only as the background for the pointer. For this reason, due to the relative positional relationship between the pointer and the dial, a three-dimensional effect in which the pattern display light approaches the front side of the pointer cannot be expressed, and a sufficiently novel appearance effect has not been produced.

  One disclosed object is to provide a display device for a vehicle that has a three-dimensional effect and produces a novel appearance effect.

The vehicle display device disclosed herein is a vehicle display device mounted on a vehicle,
A pointer (60) movable to indicate an indicator based on the state of the vehicle;
A projection unit (82) disposed on the viewer side of the pointer,
The guidelines are
An instruction unit (68) for instructing an indicator on the distal end side of the pointer;
A light emitting portion (64) disposed on the proximal end side of the pointer with respect to the pointing portion and emitting pattern display light used for displaying the pattern (PT) toward the viewing side is configured to be integrally movable. And
The projection unit is disposed to face the movable range so as to cover the movable range (RL) of the light emitting unit from the viewing side,
A pattern is displayed on the projection unit by the pattern display light projected by the light emitting unit.

  According to such a vehicle display device, the projection unit is arranged on the viewing side so as to face the movable range so as to cover the movable range of the light emitting unit on the proximal end side of the pointer from the viewing side. The pattern displayed on the projection unit by the pattern display light is recognized on the viewer side further than the light emitting unit. Therefore, based on the relative distance between the pattern displayed on the projection unit and the pointing unit on the front end side of the pointer, a three-dimensional feeling that the pattern approaches the front of the pointing unit is expressed. With such a three-dimensional expression, it is possible to provide a vehicular display device that produces a novel appearance effect that has never existed before.

  An embodiment will be described with reference to the drawings.

  As shown in FIG. 1, a vehicle display device 100 according to an embodiment of the present disclosure is installed on an instrument panel that is mounted on a vehicle and faces a seat on which an occupant who views the device 100 is seated. The vehicle display device 100 can display vehicle information toward the viewing side where the occupant is located.

  As shown in FIG. 2, the vehicular display device 100 includes a case unit 10, a mounting substrate 20, a display board 30, an image display unit 40, a plurality (two in this embodiment) of pointer display units 50, and The light transmitting plate 80 is used.

  The case portion 10 includes a back side case 11, a viewing side case 12, a plate window member 13, and a smoke plate 14. The back side case 11 is formed of, for example, synthetic resin so as to be light-shielding, and covers the mounting substrate 20 from the back side opposite to the viewing side.

  The visual recognition side case 12 arranged on the visual recognition side with respect to the back side case 11 is formed of, for example, a synthetic resin so as to be shielded from light, covers the mounting substrate 20 from the visual recognition side, and is arranged along a pointer axis AX described later. A cylindrical pointer shaft insertion cylinder portion 12a is provided.

  The plate window member 13 is formed of, for example, a synthetic resin so as to have a light shielding property, and is disposed on the viewing side from the display plate 30. The plate window member 13 is formed in a cylindrical shape having openings on the viewing side and the back side along the outer peripheral contour of the apparatus 100.

  The smoke plate 14 is formed in a curved plate shape that covers the entire surface of the viewing side opening of the plate window member 13 with a semi-translucent resin such as a colored acrylic resin or polycarbonate resin. Thereby, the display board 30, the translucent board 80, etc. will be visually recognized by a passenger | crew through a smoke board.

  The mounting substrate 20 is formed in a flat plate shape by, for example, a synthetic resin, and is disposed in an internal space formed between the back side case 11 and the visual recognition side case 12. A light emitting element 52a and a pointer driving motor 51, which will be described later, are mounted and held on the mounting substrate 20. A control circuit for controlling these elements is mounted and held.

  The display board 30 is generally called a dial, and is held and arranged on the most visible side of the viewing side case 12. The display plate 30 is formed in a flat plate shape, for example, by partially translucent or light-shielding printing on the surface of a light-transmitting substrate such as acrylic resin or polycarbonate resin. In addition, it may replace with printing and the coating may be given.

  A rectangular light-transmitting region 31 that transmits the display light of the image display unit 40 is provided in the central region of the display panel 30. In addition, in the left and right areas of the display board 30, indicators 32 are formed corresponding to the two pointer display portions 50.

  The image display unit 40 is arranged corresponding to the central region of the display board 30. The image display unit 40 includes a liquid crystal display 41 arranged in the vicinity of the display plate 30 on the back side of the display plate 30. The liquid crystal display 41 of this embodiment is a transmissive TFT liquid crystal panel using thin film transistors (TFTs), and is an active matrix liquid crystal formed from a plurality of liquid crystal pixels arranged in a two-dimensional direction. A display is adopted. The liquid crystal display 41 has a rectangular display surface 42 for displaying an image on the viewing side. The display light of the image displayed on the display board 30 passes through the light-transmitting region 31 of the display board 30 to the viewing side, and further passes through the light-transmitting board 80.

  In the image display unit 40, instead of the liquid crystal display 41, another type of display such as an organic EL display may be employed. Further, instead of the light-transmitting region 31 of the display plate 30, an opening region that transmits display light by opening may be employed.

  The two pointer display portions 50 are provided corresponding to the left and right areas of the display plate 30. The right hand pointer display unit 50 displays the speed of the vehicle as the state of the vehicle. The left hand pointer display unit 50 displays the engine speed as the state of the vehicle. The state of the vehicle displayed by the pointer display unit 50 is not limited to the speed of the vehicle and the engine speed, but the remaining amount of fuel, the temperature of the engine coolant, or the current value of an electric motor in a hybrid vehicle or an electric vehicle, etc. May be adopted.

  Since the mechanical configurations of the two pointer display units 50 are similar to each other, the right pointer display unit 50 will be described as a representative here.

  As shown in an enlarged view in FIG. 3, the pointer display unit 50 includes a pointer drive motor 51, a light supply unit 52, a connection light guide unit 53, a pointer cap 59, and a pointer 60.

  As the pointer driving motor 51, for example, a stepping motor is employed. The pointer drive motor 51 is held on the back side of the mounting substrate 20 and is driven by control by a control circuit. By such driving, it is possible to rotate the internal unit shaft 51 a that penetrates the mounting substrate 20 and is disposed on the visual recognition side with respect to the mounting substrate 20. The internal unit shaft 51a extends along the pointer shaft AX around which the pointer 60 rotates in the pointer shaft insertion tube portion 12a.

  The light supply part 52 has a plurality of light emitting elements 52a in the pointer shaft insertion cylinder part 12a. Each light emitting element 52a is held on the viewing side in the mounting substrate 20, and is disposed so as to surround the internal unit shaft 51a. For example, a light emitting diode is employed for each light emitting element 52a. Each light emitting element 52a is connected to a power source through a wiring pattern on the mounting substrate 20, and can emit light toward the viewing side with a light amount corresponding to the amount of current controlled by the control circuit.

  The connection light guide 53 is disposed in the pointer shaft insertion cylinder 12 a between the mounting substrate 20 and the display plate 30, and connects the internal unit shaft 51 a of the pointer drive motor 51 and the pointer 60, and the light supply unit 52. Is guided to the inside of the pointer 60. The connection light guide unit 53 includes a light guide body 54 and a light guide cover 58.

  The light guide main body 54 is formed to be translucent by translucent resin such as acrylic resin or polycarbonate resin. The light guide main body 54 has a light receiving cylindrical portion 55 that protrudes in a cylindrical shape toward each light emitting element 52 a of the light supply portion 52 on the outer peripheral portion of the back side. The light receiving cylinder portion 55 is arranged so that the tip thereof faces each light emitting element 52a with a small gap, so that the light from each light emitting element 52a is efficiently received, and inside the light guide main body 54. It is possible to capture. An insertion hole 56 is provided on the inner peripheral portion of the back surface side of the light guide body 54. The insertion hole 56 is recessed toward the viewing side from the light receiving cylinder portion 55 and into which the internal unit shaft 51a is inserted by press fitting.

  In the light guide main body 54, the light from the light receiving cylinder part 55 is merged with light from each part of the light receiving cylinder part 55 by a shape gradually decreasing in diameter toward the visual recognition side from the light receiving cylinder part 55, A merging light guide 57 that guides light toward the pointer 60 is provided.

  The light guide cover 58 is formed of, for example, a synthetic resin so as to be light-shielding, and has a substantially cylindrical shape that opens on both the viewing side and the back side. Particularly in the present embodiment, the light guide cover 58 is formed in white. The light guide cover 58 covers the light guide body 54 from the outer peripheral side from the light receiving cylinder portion 55 to the confluence light guide portion 57. Light leakage from the connected light guide 53 to the outside of the light taken into the light guide body 54 is suppressed by the light guide cover 58.

  The front end portion 57 a of the merging light guide portion 57 is formed in a columnar shape and is disposed on the viewing side with respect to the light guide cover 58. At the position straddling the opening hole 35 vacated in the display board 30, the leading end portion 57 a is fitted with the protruding cylindrical portion 59 a formed to protrude from the pointer cap 59 to the back side, so that the connection light guide portion 53 is , Indirectly connected to the pointer 60.

  Most of the pointer cap 59 is disposed on the visual recognition side of the display board except for the protruding cylinder portion 59a. The pointer cap 59 is formed of, for example, a synthetic resin so as to be light-shielded, and has a cap shape surrounding the shaft upper portion 61 disposed on the pointer shaft AX of the pointer 60. Since the shaft upper portion 61 of the pointer 60 is covered with the pointer cap 59, light emission from the shaft upper portion 61 to the viewing side is restricted.

  The pointer 60 is disposed on the viewing side with respect to the display plate 30 and on the back side with respect to the translucent plate, that is, between the display plate 30 and the translucent plate 80. The pointer 60 is movable so as to indicate the indicator 32 formed on the display board 30 based on the state of the vehicle. Specifically, the pointer 60 is connected to the internal unit shaft 51a via the connection light guide portion 53, so that the pointer 60 is substantially connected to the pointer shaft AX around the pointer shaft AX as the pointer drive motor 51 is driven. It rotates on a vertical virtual orbital plane OP.

  The pointer 60 is formed to be translucent, for example, with a synthetic resin such as an acrylic resin or a polycarbonate resin. The pointer 60 integrally includes an upper shaft portion 61, a light emitting unit 64, and an instruction unit 68.

  The upper shaft portion 61 is disposed on the most proximal side of the pointer 60 and is positioned on the pointer shaft AX. The shaft upper portion 61 has a light receiving projection 62 and a deflection unit 63. The light receiving protrusion 62 is disposed in the protruding cylindrical portion 59 a of the pointer cap 59 and is formed to protrude from the deflecting portion 63 toward the light guide body 54 on the back side. The light receiving protrusion 62 has a columnar shape having substantially the same diameter as the distal end portion 57a of the merging light guide portion 57, and is opposed to the distal end portion 57a with a gap. Therefore, the light supplied from the light supply part 52 and emitted from the tip part 57a is taken into the pointer 60 from the light receiving projection 62, and is guided through the light receiving projection 62 to the viewing side and deflected. The unit 63 is reached.

  The deflection unit 63 is accommodated in an accommodation space formed by the pointer cap 59. The deflecting unit 63 has a reflecting surface 63a, and the light is deflected by reflecting the light from the light receiving projection 62 toward the light emitting unit 64.

  4-6, the light emission part 64 and the instruction | indication part 68 are extended | stretched and arrange | positioned from the deflection | deviation part 63 of the axial upper part 61 to the outer peripheral side on the basis of the pointer axis | shaft AX. Of these, the light emitting portion 64 is disposed on the distal end side of the shaft upper portion 61 and on the proximal end side of the indicating portion 68 in the pointer 60. The light emitting section 64 is formed in a fan shape that extends along the track plane OP.

  On the other hand, the instruction unit 68 is disposed on the distal end side of the light emitting unit 64, that is, on the most distal end side of the pointer 60. The indicating unit 68 extends so as to protrude further to the outer peripheral side from the light emitting unit 64, and has a needle shape that tapers toward the distal end side. In particular, in the present embodiment, the indicator 68 extends from the position corresponding to the midpoint of the outer peripheral arc 64a of the light emitter 64 toward the outer periphery, so that the light emitter 64 is on the orbit plane OP with respect to the indicator 68. It protrudes on both sides in the circumferential direction.

  On the viewing side of the light emitting unit 64 and the instruction unit 68, a common flat surface 60 a provided continuously in the light emitting unit 64 and the instruction unit 68 is provided so as to face the translucent plate 80. On the other hand, on the back side of the light emitting unit 64 and the indicating unit 68, the thickness of the indicating unit 68 is set smaller than the thickness of the light emitting unit 64, so that the light emitting unit 64 is further on the back side with respect to the indicating unit 68. Overhang is formed.

  The light deflected by the deflecting unit 63 is supplied to the light emitting unit 64 and the instruction unit 68. Here, a reflective surface 69 is provided on the back side of the instruction unit 68. The reflection surface 69 is formed in an inclined surface shape that is inclined so as to go to the visual recognition side as going to the tip side. With the above thickness setting, the arrangement of elements that block light is restricted between the reflecting surface 63a of the deflecting unit 63 and the reflecting surface 69 of the indicating unit 68, and is reflected by the reflecting surface 63a of the deflecting unit 63. Part of the incident light is incident on the reflecting surface 69 of the indicating unit 68 and is further reflected by the reflecting surface 69 toward the viewing side.

  On the other hand, on the back side of the light emitting portion 64, a reflecting portion 65 constituted by a plurality of divided reflecting surfaces 65a arranged in a sawtooth shape is provided. Each divided reflecting surface 65a is formed by dividing the fan-shaped light emitting portion 64 into a circular arc shape in the radial direction, and is formed in an inclined surface shape that inclines toward the viewing side as it goes toward the tip side. The reflecting unit 65 reflects a part of the light reflected by the reflecting surface 63a of the deflecting unit 63 toward the viewing side by using each divided reflecting surface 65a. The reflecting portion 65 is formed by dividing the plurality of sawtooth-shaped divided reflecting surfaces 65a, so that the thickness of the light emitting portion 64 is made constant over the whole while establishing the function of reflecting light toward the viewing side. And it is thin. By such a thinning, for example, the distance between the pointer 60 and the display board 30 can be reduced, and the parallax between the indicator 32 on the display board 30 and the instruction unit 68 is reduced.

  Here, the sawtooth-shaped groove depth Hg in the reflecting portion 65 is set so as to become deeper from the inner peripheral side toward the outer peripheral side, and is extended to the visual recognition side as far as the divided reflection surface 65a on the outer peripheral side. Yes. As a result, the reflection efficiency can be increased even on the outer divided reflection surface 65a where the light from the deflecting unit 63 is difficult to reach, and the amount of reflected light per unit area is uniform between the inner and outer peripheral sides of the reflecting unit 65. It is planned.

  On the viewing side where a part of the flat surface 60 a is provided in the light emitting part 64, a facing part 66 that faces the translucent plate 80 is provided. The facing portion 66 has a recess 67 that is recessed from the flat surface 60a in the direction of the back surface to form the pattern PT. Here, the concave portion 67 of the present embodiment forms a pattern PT by arranging a plurality of concave holes 67 a over the entire area of the facing portion 66. Each concave hole 67a is formed in a round hole shape recessed in a truncated cone shape. The diameter Dh of each concave hole 67a is set to gradually decrease from the inner peripheral side toward the outer peripheral side. The hole depths Hh of the concave holes 67a are set to be substantially the same.

  The bottom surface and the side surface of each concave hole 67a are formed into a rough surface by being subjected to embossing or the like. Thereby, the light that is reflected by the reflecting portion 65 and travels to the viewing side is slightly diffused when entering the bottom and side surfaces of each concave hole 67a. The light that has passed through the facing portion 66 is emitted to the viewing side as pattern display light used for displaying the pattern PT.

  3 and 5, the forward path of light supplied from the light supply unit 52 is roughly indicated by broken-line arrows.

  In the present embodiment, as shown in FIG. 1, the indicator 32 corresponding to the pointer 60 on the display board 30 is arranged in a partial annular shape with the pointer axis AX as the center so as to overlap the tip end side of the pointing portion 68. The instruction unit 68 is instructed. More specifically, the index 32 has a scale 33 disposed on the relatively outer peripheral side and a character 34 disposed on the relatively inner peripheral side. In the present embodiment, the range of the predetermined angle on the lower side of the display panel 30 is an exclusion range in which the index 32 is not formed.

  For this reason, the pointer 60 basically rotates so that the instruction unit 68 indicates the range in which the index 32 is arranged. Therefore, the movable range RP of the instruction unit 68 is within the angle range in which the index 32 is arranged. It has a substantially matching fan shape. On the other hand, since the light emitting unit 64 protrudes on both sides in the circumferential direction with respect to the instruction unit 68, the movable range RL of the light emitting unit 64 is equal to the angle of the spread angle to the angle formed by the movable range RP of the instruction unit 68. It has a fan shape according to the added angle range.

  The translucent plate 80 is formed to be translucent by synthetic resin such as acrylic resin or polycarbonate resin, and is formed in a flat plate shape having a pair of plate surfaces 81a and 81b on both the viewing side and the back side. The translucent plate 80 is disposed between the display plate 30 and the smoke plate 14 on the visual recognition side with respect to the pointer 60, and is provided substantially parallel to the display plate 30 and the track plane OP. The viewing side plate surface 81a faces the viewing side. The back side plate surface 81b faces the display plate 30 and the pointer 60 by facing the back side. Therefore, the translucent plate 80 is disposed so as to cover the entire surface of the display plate 30 including the movable range RL of the light emitting portion 64 of the pointer 60 from the viewing side.

  Corresponding to the movable range of the light-emitting portion 64, the translucent plate 80 has a semi-translucent printing by applying smoke-like semi-transparent printing to the back side plate surface 81b of the translucent plate 80. A projection unit 82 is provided. The projection unit 82 is disposed so as to face the movable range RL so as to cover the movable range RL of the light emitting unit 64 from the viewing side. In particular, in the present embodiment, the projection unit 82 has a circular shape having a center on the extension line of the pointer axis AX. Is formed.

  On the other hand, the region excluding the projection portion 82 in the light transmitting plate 80 is not printed, and thus is a high transmittance region HT having a high light transmittance. As a result, the region facing the movable range RL in the translucent plate 80 is set to the low transmittance region LT having a relatively low light transmittance relative to the region HT not facing the movable range RL. The low transmittance region LT constitutes the projection unit 82.

  Since the high transmittance region HT is provided so as to face the movable range RP of the indicating unit 68, the indicating unit 68 clearly recognizes the shape of the member from the viewing side through the smoke plate 14 and the light transmitting plate 80. It is possible to be done. Since the light reflected by the reflecting surface 69 of the instruction unit 68 passes through the light transmitting plate 80 and the smoke plate 14, the entire instruction unit 68 emits light and can be visually recognized.

  On the other hand, since the light emitting unit 64 is blocked by the projection unit 82 forming the low transmittance region LT, it is difficult to recognize the member shape from the viewing side. However, the pattern display light emitted from the light emitting unit 64 is projected onto the projection unit 82. Since the projection unit 82 has translucency, part of the pattern display light projected on the projection unit 82 is transmitted to the viewing side, and the pattern PT is displayed.

  Such a pattern PT is displayed like a silhouette (shadow) floating in the projection unit 82 on the viewing side with respect to the instruction unit 68. When the instruction unit 68 and the light emitting unit 64 are integrally moved, the range in which the pattern PT is displayed moves following the movement of the instruction unit 68. Since the light emitting unit 64 is formed in a fan shape that protrudes on both sides in the circumferential direction with respect to the instruction unit 68, the pattern PT is also displayed in a fan-shaped range that extends on both sides in the circumferential direction with respect to the instruction unit 68. In particular, in this embodiment, since the concave portions 67 are formed by arranging the circular concave holes 67a, the pattern PT displayed on the projection unit 82 is also a dot-like and radar-like pattern.

(Function and effect)
The operational effects of the present embodiment described above will be described again below.

  According to the present embodiment, the projection unit 82 is disposed on the viewing side facing the movable range RL so as to cover the movable range RL of the light emitting unit 64 on the proximal end side of the pointer 60 from the viewing side. The pattern PT displayed on the projection unit 82 by the 64 pattern display light is recognized further on the viewer side than the light emitting unit 64. Therefore, based on the relative distance between the pattern PT displayed on the projection unit 82 and the pointing unit 68 on the distal end side of the pointer 60, a three-dimensional feeling that the pattern PT approaches the front of the pointing unit 68 is expressed. . Such a three-dimensional expression can provide the vehicle display device 100 in which a novel appearance effect that has never existed before is produced.

  Moreover, according to this embodiment, the light emission part 64 is formed in the fan shape which spreads along the track plane OP in which the pointer 60 rotates. When the pattern display light from the fan-shaped light emitting section 64 is projected onto the projection section 82, the pattern PT is displayed in the fan-shaped range together with the pointing section 68 of the rotating pointer 60. A display like a PPI scope can be produced. In combination with the above-described three-dimensional effect, such an effect can provide the vehicular display device 100 that is conspicuous.

  Further, according to the present embodiment, the facing portion 66 that faces the projection portion 82 in the light emitting portion 64 has the recessed portion 67 that is recessed in the direction of the back surface to form the pattern PT. Since the pattern display light of the pattern PT corresponding to the concave portion 67 is emitted from the facing portion 66, the projection portion 82 can easily display the pattern PT that moves integrally with the instruction portion 68.

  Further, according to the present embodiment, the light emitting unit 64 includes the reflecting unit 65 that reflects the pattern display light from the light supply unit 52 toward the facing unit 66 on the back side opposite to the facing unit 66. If it does in this way, the light emission part 64 can be thinned, raising the brightness | luminance of pattern PT. Since the light emitting unit 64 is thinned, the degree of freedom of arrangement of the pointer 60 is increased. Therefore, the positional relationship with the projection unit 82 can be easily adjusted so that the stereoscopic effect is increased.

  Further, according to the present embodiment, the projection unit is formed by setting the region facing the movable range RL of the light emitting unit 64 in the light transmitting plate 80 as the low transmittance region LT. In this way, it is possible to display the pattern PT such that the projection unit 82 floats on the viewer side with respect to the pointer 60, and it is possible to provide the vehicular display device 100 that is conspicuous.

  In addition, according to the present embodiment, the display panel 30 is further provided on the back side of the pointer 60 and on which the indicator 32 is formed. The three-dimensional effect is further enhanced by the three-way parallax of the pointer 60, the index 32 on the back side of the pointer 60, and the pattern PT on the viewer side of the pointer 60.

(Other embodiments)
Although one embodiment has been described above, the present invention is not construed as being limited to the embodiment, and can be applied to various embodiments without departing from the scope of the invention.

  Specifically, as a first modification, as illustrated in FIGS. 7 and 8, the light emitting unit 64 may be formed in a fan shape projecting to one side in the circumferential direction with respect to the instruction unit 68. In the example of FIGS. 7 and 8, the ridge portion 64 b is provided at the edge on one side in the circumferential direction where the light emitting portion 64 does not protrude. The protruding portion 64 b protrudes from the facing portion 66 toward the viewing side along the extending direction of the indicating portion 68. The projection 64b shields light from one side of the circumferential direction where the light emitting unit does not protrude, so that the pattern PT of the projection unit 82 is reliably displayed only on one side of the circumferential direction with respect to the pointing unit 68. It has become. In addition, it is suitable for the protrusion 64b to be formed into a rough surface by a texture process or the like. In addition, an inclined surface that inclines toward the visual recognition side (inclined by 45 degrees, for example) may be provided on the side adjacent to the concave portion 67 in the ridge portion 64b as the distance from the concave portion 67 in the circumferential direction increases.

  As a second modification, the light emitting unit 64 may be formed in a rectangular shape other than the fan shape, a triangular shape, or the like as long as the light emitting unit 64 is disposed on the proximal end side with respect to the instruction unit 68.

  As a third modification, the concave portion 67 that forms the pattern PT in the facing portion 66 is not limited to a configuration in which a plurality of round hole-shaped concave holes 67a are arranged, and various recesses corresponding to the pattern PT can be adopted. .

  As a fourth modification, a convex portion that protrudes toward the viewing side may be provided in the facing portion 66 in order to form the pattern PT.

  As a fifth modification, a pattern PT may be formed on the projection unit 82 side. For example, in the example shown in FIG. 9, the projection unit 82 forms a printed pattern 82 a on the back side plate surface 81 b of the translucent plate 80 by semi-translucent or light-shielding printing. A pattern display light is projected to display a pattern PT corresponding to the printed pattern 82a. In this case, it is not necessary to provide the recessed part 67 which forms pattern PT in the opposing part 66 of the light emission part 64. FIG. For example, the facing portion 66 may be formed in a planar shape that simply transmits the light from the reflecting portion 65, or the facing portion 66 is configured to emit light to the viewing side while diffusing the light from the reflecting portion 65. May be.

  As a sixth modification, the projection unit 82 may not be formed in a circular shape as long as the projection unit 82 is disposed to face the movable range RL so as to cover the movable range RL of the light emitting unit 64 from the viewing side. For example, the projection unit 82 may be formed in a fan shape excluding the angle range side where the partial annular index 32 is not disposed.

  As a modified example 7, the projection unit 82 may be formed by printing on the viewing side plate surface 81a. Moreover, the projection part 82 may be formed by sticking the smoke-like semi-transparent film to the visual recognition side board surface 81a or the back side board surface 81b. Moreover, the projection part 82 may be formed semi-translucent by coloring the base material of the translucent board 80 by dyeing | staining etc. FIG.

  As a modified example 8, the indicator 32 may not be formed on the display panel 30. For example, as shown in FIG. 10, the indicator 32 may be formed on the translucent plate 80 by printing on the translucent plate 80 or providing unevenness on the translucent plate 80. Further, for example, a display device such as the liquid crystal display device 41 may be arranged so as to overlap the instruction unit 68 so that the index 32 is displayed as an image of the display device.

  As a ninth modification, the pointer 60 does not have to be configured to rotate around the pointer axis AX as long as the pointing unit 68 and the light emitting unit 64 are configured to move integrally. For example, the pointer 60 may be configured to move linearly. In this case, the projection unit 82 may be formed in a belt shape extending in the movable direction of the pointer 60 so as to cover the movable range RL of the light emitting unit 64 from the viewing side.
