Description

  The present invention relates to a pointer for an instrument used in various vehicles such as automobiles.

  Conventionally, as this kind of instrument guidelines, for example, those described in Patent Document 1 below are known. The instrument pointer described in Patent Document 1 includes an indicator that extends in a longitudinal direction in a direction substantially orthogonal to the rotation axis of the drive device, and a pointer cap that covers the center of rotation of the indicator, and the rotation of the indicator A light receiving portion that receives light from a light source disposed behind the pointer cap and guides the light to the distal end side of the pointing portion and the pointer cap side is formed in the center portion. In this case, the said instruction | indication part consists of translucent resin materials, for example, and instruct | indicates index parts, such as a number provided on the indicator plate and a scale.

The pointer cap is made of a light-transmitting colored resin material, is formed in a substantially cylindrical cup shape, and has a disk-shaped upper surface portion (base portion) positioned directly above the rotation center portion of the pointer, and the upper surface portion. A cylindrical side wall portion extending so as to hang from the outer periphery along the axial direction of the rotation shaft, and a substantially circular opening portion formed so as to face the upper surface portion are provided. Therefore, when the light source is turned off, the incident light from the front side of the pointer cap reflects the upper surface and the side wall surface, so that the pointer cap mainly has the predetermined upper surface only. It is visually recognized by the driver (observer) so as to have one color. On the other hand, when the light source is turned on, light emitted from the light source passes through the upper surface portion and the side wall portion, so that only the upper surface portion of the pointer cap mainly has the first color or the first color. The light was displayed to the driver so as to have a predetermined second color different from the color.

  The driving device 3 is composed of a movable magnet-type instrument or a stepping motor, the main part of which is mounted behind the circuit board 1 so that the rotating shaft 2 penetrates the circuit board 1 and is appropriately connected by means such as soldering. Electrical connection is made to the wiring pattern.

  As shown in detail in FIG. 3, the pointer 4 includes a pointing portion 41 made of a light-transmitting synthetic resin extending in a longitudinal direction substantially orthogonal to the rotation shaft 2 of the driving device 3, and a rotation center portion R of the pointing portion 41. A pointer cap 42 that covers the outer periphery, and receives light emitted from the light source 6 disposed behind the rotation center R of the indicator 41, and reflects and guides the light toward the tip of the indicator 41. A light receiving portion 43 is formed. In the present embodiment, part of the light reaching the light receiving unit 43 is also guided to the pointer cap 42 side. Reference numeral 44 denotes a red hot stamp layer formed on the back surface of the instruction unit 41.

  In this case, the pointer cap 42 is made of, for example, a black light-shielding synthetic resin, and is formed of a substantially circular through hole that is located immediately above the rotation center portion R of the pointing portion 41 and corresponds to (opposes) the rotation center portion R. A substantially annular base portion 42b having a penetrating portion 42a, a substantially cylindrical side wall portion 42c extending from the outer periphery of the base portion 42b along the axial direction of the rotary shaft 2, and a base portion 42b having an opening.

And a later-described plastic sheet 9. The side wall portion 42c is formed with a notch portion 42e formed of a slit for exposing the indication portion 41 around the pointer cap 42.

  The inner wall surface of the through-hole 42a formed of a substantially circular through-hole has a substantially “U” -shaped cross-section for disposing an annular portion that is a peripheral edge of a plastic sheet whose outer shape described later is a substantially circular shape. An annular groove portion 42f made of an annular groove is formed.

  A plastic sheet (covering member) 9 having a substantially circular outer shape disposed in such an annular groove portion 42f so as to cover the rotation center portion R of the pointer 4 (indicating portion 41) is made of polycarbonate or the like as shown in detail in FIG. A thin plate-like light-transmitting substrate 91, a spin-shaped streak pattern (hairline pattern) 92 formed on the surface of the annular convex portion described later after drawing processing described later, and a substrate excluding the formation portion of the streaked pattern 92 A black ground color portion 93 formed on the back surface (back surface) portion of 91, and a transflective portion (reflecting portion) 94 made of a semi-transmissive layer formed on the back surface of the substrate 91 so as to correspond to the streak pattern 92; In this case, the entire streak pattern 92 made of a hairline pattern has a substantially ring shape.

  The ground color portions 93 are respectively provided in an outer region of the streak pattern 92 that is an annular region surrounding the streak pattern 92 and in an inner region of the streak pattern 92 that is a circular region surrounded by the streak pattern 92, and is a black light-shielding ink. Thus, printing is performed on the back surface portion of the substrate 91 corresponding to the inner region and the outer region using means such as screen printing. If necessary, an overcoat layer (not shown) may be provided on the surface portion of the substrate 91 corresponding to the ground color portion 93. Further, the ground color portion 93 can also be formed on the surface portion of the substrate 91 excluding the formation portion of the streak pattern 92, and thus overlaps the ground color portion 93 formed on the surface of the substrate 91 in this manner. An overcoat layer may be provided.

  The transflective portion 94 reflects external light such as natural light incident from the front of the pointer 4 (resulting in passing through the substrate 91 as a result) to the viewer side and transmits light from the light source 6, for example, silver And includes a non-printed cutout portion 95 of the ground color portion 93 (in other words, includes a cutout portion 95 and a boundary portion between the ground color portion 93 and the cutout portion 95). ) As shown in FIG.

  By the way, in the case of this embodiment, the plastic sheet 9 is formed so as to have a three-dimensional shape (three-dimensional modeling), and has a substantially disc shape corresponding to the inner region of the streak pattern 92 located at a substantially central portion. The flat plate portion 96, an annular convex portion (raised portion) 97 having a substantially convex shape in which the substrate 91 is partially raised so as to surround the flat plate portion 96, and the flat plate portion 96 are set to be substantially flush with each other. A substantially annular plate-like flat portion 98 that further surrounds the annular convex portion 97, and after forming the ground color portion 93 and the semi-transmissive reflective portion 94 on the back surface of the substrate 91, the substrate 91 is thermally deformed. A plastic sheet 9 having a three-dimensional shape is formed by drawing (drawing).

  In the case of the present embodiment, the annular convex portion 97 is formed of a ring-shaped raised shape (projecting shape) in which the portion of the substrate 91 corresponding to the punched portion 95 is raised on the surface side of the base portion 91, but is not limited thereto. For example, the annular convex portion 97 may have a dome shape (bag shape) or a raised shape in which it is raised in a mountain shape. Similarly, the flat plate portion 96 is not limited to a circular flat plate shape, and may be set to a spherical raised shape that is raised in the same direction as the annular convex portion 97, for example.

  Further, in the plastic sheet 9, a streak pattern 92 made of a hairline pattern not previously formed on the substrate 91 before the drawing process is formed (transferred) on the surface of the annular convex portion 97 during the drawing process. It has become.

  Specifically, although not shown, the streak pattern 92 is formed on the annular convex part 97 at the same time as the flat plate part 96, the annular convex part 97, and the flat support part 98 at the time of the drawing process, thereby forming the streak pattern 92. The bottom side inner wall surface in the annular recess of the drawing mold corresponding to the location to be formed (that is, the bottom side inner wall surface in the annular recess of the drawing mold for forming the annular projection 97) is concentric. Are provided with a plurality of fine grooves. Therefore, at the time of the drawing process, the annular convex portion 97 becomes a substantially convex shape by drawing the substrate 91 corresponding to the punched portion 95 along the annular concave portion. Is closely attached to the inner wall surface on the bottom side of the annular recess provided with the plurality of fine grooves, and as a result, the surface of the annular convex portion 97 after the drawing is formed by the lines formed by the plurality of fine grooves. A pattern (hairline pattern) 92 is applied simultaneously with the drawing process.

  In the case of the present embodiment, the plastic sheet 9 drawn in this manner has an annular groove provided on the inner wall surface of the penetrating portion 42a in the pointer cap 42 (base portion 42b). It is integrally formed with the pointer cap 42 so as to close the penetrating portion 42a in a state of being fitted to 42f.

  Specifically, after the drawn plastic sheet 9 is set in an injection mold (not shown), the injection mold is closed, and then the pointer cap 42 (base portion) is used by using an injection molding machine (not shown). 42b, the side wall portion 42c) is injected into the injection mold. After injecting the molten resin, the molten resin is cooled and solidified, and the injection mold is opened and taken out, so that the plastic sheet 9 has an annular groove portion whose flat portion 98 is provided in the base portion 42b. In a state of being fitted to 42f, the needle cap 42 is integrally formed so as to close the through portion 42a.

  The pointer cap 42 integrally formed with the plastic sheet 9 is fixed to the instruction portion 41 so as to cover the rotation center portion R of the instruction portion 41. Thereby, the observer can directly visually recognize the surface of the plastic sheet 9 (the protruding side of the annular convex portion 97) and the surface of the base portion 42b surrounding it. This means that the visible region of the pointer cap 42 is constituted by the surface of the plastic sheet 9 (the side from which the annular convex portion 97 projects) and the surface of the base portion 42b.

  The indicator plate 5 includes a speed display unit for displaying the speed of the vehicle. The indicator plate 5 has an arcuate array shape along the rotation trajectory of the pointer 4, and includes a scale 51a and a number 51b to be instructed by the instruction unit 41. And a background portion 52 that forms the background of the indicator portion 51 (see FIG. 1).

  The indicator portion 51 and the background portion 52 are thin plate-like light-transmitting materials that serve as a base material of the indicator plate 5 with the indicator portion 51 made of white light-transmitting ink and the background portion 52 made of black light-shielding ink. The surface of the conductive substrate 53 is formed by printing using means such as screen printing (see FIG. 2). Reference numeral 54 denotes a substantially circular hole through which the rotary shaft 2 passes, and the hole 54 is formed in an approximately central part of the indicator plate 5.

  The light source 6 is composed of, for example, a chip-type light emitting diode that emits red light. A plurality of light sources 6 are arranged on the circuit board 1 corresponding to the rotation center portion R of the pointer 4, and the annular convex portion 97 provided in the indication portion 41 and the pointer cap 42. Is a light emitter that emits light.

  The indicator light source 7 is composed of, for example, a chip-type light emitting diode that emits white light. A plurality of indicator light sources 7 are arranged on the front side of the circuit board 1 corresponding to a first reflecting portion, which will be described later, of the case body 8 to cause the indicator portion 51 to emit light. It is a luminous body.

  The case body 8 is made of, for example, white synthetic resin, and is emitted from the light source 6 and the index light source 7 as a holding body that holds the index plate 5 and is positioned between the circuit board 1 and the index plate 5. A cylindrical shape that has a function as a reflector that reflects light forward, and has a hollow portion 81 that corresponds to the hole 54 of the indicator plate 5 and guides the light from the light source 6 to the light receiving portion 43 of the pointer 4. A portion 82, a first reflecting portion 83 extending obliquely toward the indicator plate 5 so as to surround the tubular portion 82, and facing the indicator light source 7, and an indicator plate 5 formed on the distal end side of the tubular portion 82 A pair of locking claws 84 that fit into the holes 54, an opening 85 that houses the indicator light source 7, and a dish-shaped annular wall that is close to the indicator plate 5 from the opening 85 toward the outer periphery. A second reflecting portion 86; and a peripheral wall portion 87 surrounding the outer periphery of the second reflecting portion 86. .

  In this case, the first reflecting portion 83 of the case body 8 constitutes a reflecting surface that reflects light from the index light source 7 mainly radially toward the outer periphery, and the second reflecting portion 86 of the case body 8. Constitutes a reflecting surface for reflecting light reflected on the outer periphery through the first reflecting portion 83 toward the indicator plate 5 side.

  According to this embodiment, when the light source 6 and the indicator light source 7 are turned off, the indicator 41 of the pointer 4 has the outside light incident from the front side of the pointer 4 incident on the indicator 41 and is red. The surface of the hot stamp layer 44 is reflected so as to have a red color.

  In addition, the base portion 42b of the visible region of the pointer cap 42 in the pointer 4 has a black color that is the color tone of the base portion 42b when the external light incident from the front side of the pointer cap 42 reflects the surface of the base portion 42b. Visible. Further, in the flat plate portion 96 and the flat portion 98 that are the visible region, the outside light passes through the plate portion 96 and the 91 portions of the substrate corresponding to the flat portion 98, and this transmitted light passes through the surface of the ground color portion 93. By reflecting, it is visually recognized to have black which is the color tone of the ground color portion 93 itself. In addition, the remaining ring-shaped convex portion 97 which is the visible region passes through (transmits) the streak pattern 92 and the substrate 91 and reflects on the surface of the transflective portion 94, thereby reflecting the transflective portion 94. It is visually recognized by a hairline pattern against the background of its own color of silver.

  Therefore, the indicator cap 42 is displayed such that a ring-shaped hairline pattern with a silver base as shown in FIG. 5 protrudes forward of the black background portion with three-dimensional modeling by the protruding shape of the annular convex portion 97. Visible as a design. In other words, since the three-dimensional effect of the pointer cap 42 is emphasized by the three-dimensional modeling with the hairline pattern, it is possible to realize a new way of showing the fun with the pointer cap.

  When the indicator light source 7 is turned off, the external light reflects the surfaces of the indicator portion 51 and the background portion 52, so that the indicator portion 51 is visually recognized as having the white color that is the indicator portion 51 itself, and the background. The part 52 is visually recognized so as to have black which is the color tone of the background part 52 itself.

  When the light source 6 and the indicator light source 7 are turned on, the red light emitted from the light source 6 is guided to the front side (the pointer 4 side) through the cavity portion 81 of the case body 8 and the hole portion 54 of the indicator plate 5. Then, the light reaches the light receiving unit 43. Further, the red light that has reached the light receiving unit 43 is reflected and guided by the light receiving unit 43 to the distal end side of the instruction unit 41, and the pointer that passes through the light receiving unit 43 and is located directly above the light receiving unit 43. It is roughly divided into irradiation light irradiated on the cap 42 (plastic sheet 9) side.

  The reflected light reflected and guided to the distal end side of the instruction unit 41 is colored by the hot stamp layer 44, so that the instruction unit 41 emits red light. On the other hand, the irradiation light that passes through the light receiving portion 43 and is irradiated on the pointer cap 42 (plastic sheet 9) side passes through 94 transflective portions corresponding to the punched portion 95 in the plastic sheet 9. Then, the red transmitted light that passes through the transflective portion 94 is further transmitted through the annular convex portion 97 (91 locations corresponding to the punched portion 95) located immediately above the transflective portion 94, and the pointer cap 42. The light is emitted to the front side of the (plastic sheet 9).

  The irradiation light is also supplied to the back surface of the flat plate portion 96 and the flat support portion 98 of the plastic sheet 9 or the back surface of the base portion 42b and the inner wall surface of the side wall portion 42c of the pointer cap 42. The light supplied to the back surface of the support portion 98 is absorbed by the ground portion 93 formed on the back surface of the flat plate portion 96 and the flat support portion 98 and is not emitted to the front side of the plastic sheet 9. . The light supplied to the back surface of the base part 42b and the inner wall surface of the side wall part 42c is formed of a black synthetic resin material having a light shielding property on the base part 42b and the side wall part 42c. In a non-light emitting state.

  Accordingly, the irradiation light passes through only the annular convex portion 97 and does not pass through the other portions. As a result, the pointer cap 42 transmits the red light transmitted through the annular convex portion 97 as shown in FIG. A ring-shaped light emitting portion L having a red color is formed by light. The ring-shaped light-emitting portion L is lit and displayed as a display design that protrudes forward of the black background portion with three-dimensional modeling by the protruding shape of the annular convex portion 97. In other words, since the three-dimensional effect of the ring-shaped light-emitting portion is imparted with the light emission of this three-dimensional modeling, it is possible to realize a novel way of looking interesting with the pointer cap.

  Further, when the annular convex portion 97 (ring-shaped light emitting portion L) emits light, the streak pattern (hairline pattern) 92 that is visually recognized when the light source 6 is turned off is canceled and is not visually recognized. Therefore, only the display design changes while maintaining the three-dimensional appearance of the pointer cap 42 at all times when the light source 6 is turned on and off, so that the appearance of the pointer cap becomes novel both when the light source is turned on and off. Can be improved.

  The white light emitted from the indicator light source 7 is supplied into the translucent base material 53 through the first reflecting portion 83 and the second reflecting portion 86 of the case body 8 and passes through the translucent base material 53. The transmitted light passes through the indicator portion 51, so that the scale 51a and the number 51b of the indicator portion 51 emit white light.

  Further, in the present embodiment, the covering member 9 is made of a plastic sheet that is drawn so as to have the annular convex portion 97, whereby the width dimension M of the annular convex portion 97 protruding on the pointer cap 42 (see FIG. 4). Can be set freely, and the degree of freedom in design is improved. For example, the width dimension of the annular protrusion 97 can be set to a narrow dimension of about 3 mm.

  Further, in this embodiment, the plastic sheet 9 and the base portion 42 are integrally formed by insert molding, so that the process of assembling the plastic sheet 9 and the base portion 42 is not required when the instrument pointer is assembled. Can be improved.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8. The same or corresponding parts as those in the first embodiment are denoted by the same reference numerals. Detailed description thereof is omitted. FIG. 7 is a cross-sectional view of the main part of the instrument pointer according to the second embodiment of the present invention, and FIG. 8 is an enlarged cross-sectional view of the plate-like member according to the second embodiment.

  The second embodiment differs from the first embodiment in that a substantially circular plate-like member 10 made of an acrylic resin or the like is used instead of the drawn plastic sheet 9 and is substantially circular. The substantially disk-shaped plate-shaped member 10 and the pointer cap 42 are integrally formed so as to close the through portion 42a.

  Specifically, as shown in FIGS. 7 and 8, the plate-like member (covering member) 10 has a substantially disk shape, and a light-transmissive substrate 10 a having a substantially disk shape; An annular convex portion (bump portion) 10b formed to protrude on the surface of the substrate 10a and a ring-shaped streak pattern (hairline pattern) 10c formed on the surface of the annular convex portion 10b are provided. A ground color portion 10d is formed on the back surface portion of the substrate 10a. Further, a semi-transparent reflecting portion (reflecting portion) 10f is formed in the punched portion 10e on which the ground color portion 10d is not printed so as to cover the punched portion 10e and the boundary portion between the punched portion 10e and the ground color portion 10d. .

  That is, instead of the substrate 91, the annular convex portion 97, the streaks pattern 92, the ground color portion 93, the cutout portion 95, and the semi-transmissive reflection portion 94 employed in the first embodiment, the substrate 10a, The annular convex portion 10b, the streak pattern 10c, the ground color portion 10d, the cutout portion 10e, and the transflective portion 10f are employed. In this case, the plate-like member 10 is integrally formed with the base portion 42b of the pointer cap 4 so as to close the through portion 42a by the same method (insert molding) as in the first embodiment. The streak pattern 10 c is configured to be transferred to the surface of the annular convex portion 10 b when the plate-like member 10 is molded.

  Also in the second embodiment, when the light source 6 is turned off, the base portion 42b in the visible region of the pointer cap 42 is visually recognized as having a black color when the outside light reflects the surface of the base portion 42b. Further, the substrate 10a portion excluding the annular convex portion 10b which is the visible region transmits the outside light through the substrate 10a portion excluding the annular convex portion 10b, and this transmitted light reflects the surface of the ground color portion 10d. Thus, the base portion 42b is visually recognized as having the same black color. In addition, the remaining annular convex portion 10b, which is the visible region, has a silver color as a background by allowing the external light to pass (transmit) through the streak pattern 10c and the substrate 10a and reflect on the surface of the transflective portion 10f. It is visually recognized by the hairline pattern.

  Therefore, the pointer cap 42 is visually recognized so that the ring-shaped hairline pattern having the silver color as a base protrudes forward of the black background portion with the three-dimensional modeling by the protruding shape of the annular convex portion 10b. That is, since the three-dimensional effect of the pointer cap 42 is emphasized by this three-dimensional modeling with a hairline pattern, the same effects as those of the first embodiment can be obtained.

  On the other hand, when the light source 6 is turned on, the red light emitted from the light source 6 is guided to the front side (pointer 4 side) through the cavity portion 81 of the case body 8 and the hole portion 54 of the indicator plate 5 to receive the light receiving portion 43. To reach. Further, the red light that has reached the light receiving unit 43 is reflected and guided by the light receiving unit 43 to the distal end side of the instruction unit 41, and the pointer that passes through the light receiving unit 43 and is located directly above the light receiving unit 43. It is roughly divided into irradiation light irradiated on the cap 42 (plate member 10) side.

  The reflected light reflected and guided to the distal end side of the instruction unit 41 is colored by the hot stamp layer 44, so that the instruction unit 41 emits red light. On the other hand, the irradiation light that passes through the light receiving portion 43 and is irradiated on the pointer cap 42 (plate member 10) side passes through the semi-transmissive reflection portion 10f corresponding to the extraction portion 10e in the plate member 10. Then, the red transmitted light that passes through the transflective portion 10f further passes through the annular convex portion 10b (a portion of the substrate 10a corresponding to the punched portion 10e) located immediately above the transflective portion 10f and passes through the pointer cap 42. The light is emitted to the front side of the (plate-like member 10).

  As in the first embodiment, the irradiation light passes through only the annular protrusion 10b and does not pass through the other portions. As a result, the pointer cap 42 transmits the red light that passes through the annular protrusion 10b. A ring-shaped light emitting portion having a red color is formed by light. Such a ring-shaped light-emitting portion is displayed in a light-emitting manner so as to protrude forward of the black background portion with three-dimensional modeling by the protruding shape of the annular convex portion 10b. That is, since the three-dimensional effect of the ring-shaped light-emitting portion is imparted with the light emission of this three-dimensional modeling, it is possible to obtain the same effect as that of the first embodiment.

  Further, when the annular convex portion 10b (ring-shaped light emitting portion) emits light, the streak pattern (hairline pattern) 10c that has been visually recognized when the light source 6 is turned off is canceled and is not visually recognized. Therefore, only the display design changes while maintaining the three-dimensional appearance of the pointer cap 42 at all times when the light source 6 is turned on and off, so that the appearance of the pointer cap becomes novel both when the light source is turned on and off. Can be improved.

  In the second embodiment, since the plate-like member 10 and the base portion 42 are integrally formed by insert molding, the step of assembling the plate-like member 10 and the base portion 42 is not required when assembling the instrument pointer. Therefore, productivity can be improved.

  Further, in each of the above embodiments, the hairline patterns 92 and 10c are formed on the surfaces of the annular protrusions 97 and 10b, and the ring-shaped hairline patterns 92 and 10c having a silver color as a base when the light source 6 is turned off are formed on the annular protrusions 97. Although the example visually recognized so that it protrudes ahead of a black background part with the three-dimensional modeling by the protruding shape of 10b was demonstrated, it is also possible to abolish the hairline patterns 92 and 10c, for example. In this case, when the light source 6 is turned off, the three-dimensional modeling by the protruding shape of the annular convex portions 97 and 10b protrudes forward of the black background portion.

  In each of the above embodiments, the base portion 42b of the pointer cap 42 is made of a black light-shielding synthetic resin, and the ground color portions 93 and 10d provided in the plastic sheet 9 and the plate-like member 10 are black-type light-shielding having the same color as the base portion 42b. The example formed using the light-sensitive ink has been described. For example, the surface of the base portion 42b made of a light-transmitting synthetic resin has a light-shielding metallic tone surface color made of silver by means of vapor deposition or painting. The ground color portions 93 and 10d may be formed so as to have a silver color tone with a light-shielding mirror ink (or light-shielding rainbow ink).

  In this case, when the light source 6 is turned off, the base portion 42b, the ground color portions 93 and 10d, and the transflective portions 94 and 10f all have a silver color tone. When the light 6 is turned on, the red light emitted from the light source 6 is transmitted through the transflective portions 94 and 106 and emitted to the front side of the annular protrusions 97 and 10b. The red light transmitted through the portions 97 and 10b forms a red-shaped ring-shaped light emitting portion. Since the ring-shaped light-emitting portion is displayed in a light-emitting manner so as to protrude forward of the silver-colored background portion with the three-dimensional modeling by the protruding shape of the annular convex portions 97 and 10b as the light source 6 is turned on, Similar effects can be obtained.

  In each of the above-described embodiments, the base portion 42b of the pointer cap 42 is made of a black light-shielding synthetic resin, and the ground color portions 93 and 10d provided in the plastic sheet 9 and the plate-like member 10 are light-shielding in black with the same color as the base portion 42b. However, the base 42b and the ground color portions 93 and 10d can be set to different colors instead of the same color. For example, the surface of the base 42b made of a translucent synthetic resin can be used. May be formed to have a light-shielding metallic tone surface color made of silver by means such as vapor deposition or painting, and the ground color portions 93 and 10d may be formed using black light-shielding ink.

  In each of the above embodiments, the example has been described in which the raised portions 97 and 10b formed to protrude from the surfaces of the substrates 91 and 10a are annular convex portions. However, any shapes can be applied to the raised portions 97 and 10b. For example, a double ring formed of a projection shape composed of a frame-shaped convex portion, a first annular convex portion having a small diameter, and a second annular convex portion having a large diameter surrounding the first annular convex portion. It is good also as a protrusion shape which consists of a convex part. It goes without saying that a hairline pattern can be applied to the surface of the frame-shaped convex portion or the double annular convex portion as necessary.

  Further, in each of the above embodiments, the reflecting portions 94 and 10f reflect the outside light to the observer side and transmit the light from the light source 6, for example, from a translucent hot stamp layer having a silver color tone. In the example described above, for example, the reflecting portions 94 and 10f are appropriately colored in a different color from the ground color portions 93 and 10d that reflect the external light to the observer side and transmit the light from the light source 6. You may form with the semi-permeable coloring layer which has.

  Specifically, for example, when the ground color portions 93 and 10d are black, the reflection portions 94 and 10f are yellow, and the light emission color of the light source 6 is red, the color tone of the reflection portions 94 and 10f itself is set when the light source 6 is turned off. A ring-shaped hairline pattern based on a certain yellow color is visible so as to protrude forward of the black background part with three-dimensional modeling by the protruding shape of the annular convex portions 97 and 10b. A ring-shaped light emitting portion having a substantially orange color which is a mixed color of yellow is formed. The substantially orange ring-shaped light-emitting portion is lit and displayed so as to protrude forward of the black background portion with the three-dimensional modeling by the protruding shape of the annular convex portions 97 and 10b.
