The black print layer is also formed on the back surface of the support body 9, and the black print layer formed on the back surface of the support body 9 passes through the first reflective portion 43 of the light guide body 4 and the second penetrating portion. The light diffusely reflected on the 41 side is prevented from being supplied into the support 9.

  The raised portion 93 is a convex portion that is raised from the surface 95 of the support body 9 located outside the inner annular projecting portion 92 toward the rotating body 7 (disk portion 74), and the surface thereof is a curved surface (sphere). The shape is set. In this embodiment, three raised portions 93 are formed at equal intervals so as to follow the disc portion 74. Accordingly, when the rotating body 7 is assembled to the support body 9, the inner annular projecting portion 92 is inserted (guided) along the inner edge of the fourth through portion 71, so that the rotating body 7 is supported by the support body 9. However, at this time, since the rotating body 7 is supported by the support body 9 so that the back surface of the disk portion 74 is in point contact with the raised portion 93, the frictional resistance between the rotating body 7 and the support body 9 is suppressed, As a result, the rotating body 7 can be smoothly rotated.

The covering member 10 includes a facing plate 110, a circuit board 120 mounted and fixed in the facing plate 110, and a light source 130 that emits light from the indicator portion 52 and the instruction portion 62. The light source 130 emits light. The circuit board 120 is mounted on the back surface so that the surface faces the pointer 6 side.

  The facing plate 110 is made of a black plate material having a sixth penetrating portion 111 corresponding to the fifth penetrating portion 91, and the material is made of a light-shielding synthetic resin. The facing plate 110 is formed with an inner annular protrusion 112, an outer annular protrusion 113, and a wall 114. The inner annular protrusion 112 extends to the back (boundary side of the base 61 and the indicator 62) so as to surround the sixth penetrating part 111, and only the indicator 62 of the pointer 6 is exposed, so that the back of the covering member 10 is exposed. It consists of the standing wall part which makes it difficult to see the base 61 and the rotary body 7 which are located in. Note that the sixth penetrating portion 111 may be a transparent portion instead of the penetrating portion. The outer annular protrusion 113 is positioned outside the inner annular protrusion 112 and extends toward the upper surface of the outer annular protrusion 33 of the case body 3.

  The circuit board 120 is formed of a substantially annular hard circuit board having a seventh through part 121 corresponding to the sixth through part 111, and is formed in a recess formed by both the projecting parts 112 and 113 and the wall part 114. It is stored and fixed using appropriate means such as a hook. In the circuit board 120, a light source 130 and various circuit components (not shown) such as a resistor and a capacitor are conductively connected to a wiring pattern.

  The light source 130 is composed of, for example, a chip-type light emitting diode that emits white light, and a plurality of light emitting surfaces are arranged in an arc shape on the back side of the circuit board 120, and the light emitting surface of the light guide 4 is located at a position where the pointer 6 is not located. It faces the first incident portion 42 and faces the second incident portion 64 of the pointer 6 at the position where the pointer 6 is located. When the light source 130 is turned on, the light emitted from each light source 130 is incident on the first incident portion 42 of the light guide 4 at a position where the pointer 6 is not located, and is emitted by the first incident portion 42. The light introduced into the light guide 4 is diffusely reflected toward the second penetrating portion 41 so as to follow the indicator plate 5 through the first reflecting portion 43 positioned immediately below the first incident portion 42. Further, the diffusely reflected light diffusely reflected to the second penetrating portion 41 side is emitted from the surface portion of the light guide 4 in contact with the back surface of the indicator plate 5 and is transmitted through the indicator portion 52, whereby the indicator portion 52 emits white light.

  Moreover, in the location where the pointer | guide 6 is located, the light emitted from the two adjacent light sources 130 among each light source 130 injects into the 2nd incident part 64 located in the outer side of the base 61 which consists of a substantially fan shape, respectively. The light taken into the base 61 by the second incident portion 64 reaches the second reflecting portion 65 located immediately below the second incident portion 64. The light that has reached the second reflecting portion 65 passes through the second reflecting portion 65 and the reflected light that is reflected and guided by the second reflecting portion 65 to the front end side (end portion C2 side) of the indicating portion 62. Thus, the light is roughly divided into irradiation light irradiated on the first incident portion 42 side of the light guide 4 positioned directly below the second reflecting portion 65.

  The reflected light reflected and guided to the end C2 side of the instruction unit 62 is colored by the translucent hot stamp layer 66, so that the instruction unit 62 emits red light. Further, the irradiation light that passes through the second reflecting portion 65 and is irradiated to the light guide 4 side is supplied into the light guide 4 through the first incident portion 42 of the light guide 4, and the indicator portion 52 is white. Flashes on.

  As described above, when each light source 130 is turned on, the indicator section 52 emits white light and the instruction section 62 emits red light. In addition, the instruction section 62 that emits red light corresponds to the first fluoroscopic section in accordance with the rotational drive of the driving device 8. In this embodiment, the display unit 21 that moves in conjunction with the instruction unit 62 is displayed on the display image. Is displayed. Accordingly, since the display unit 21 connected to the instruction unit 62 of the pointer 6 can be added and displayed using the display image of the display device 2, it is as if the length of the instruction unit 62 is displayed on the observer side. It is visually recognized as being extended to the center point C1 of the display surface of the device 2, that is, the total length of the indication unit 62 and the length of the display unit 21 is visually recognized as the indication unit 62. The visibility of the instruction unit 62 (pointer 6) can be improved.

  In the present embodiment, the display color of the indication unit 62 of the pointer 6 and the display color of the display unit 21 are made the same color, so that it can be visually recognized as if it is a single pointer. Visibility can be improved.

  In the case of the present embodiment, even when the light source 130 is not lit, external light from the front side of the pointer 6 is reflected forward by the red translucent hot stamp layer 66 formed on the front surface of the indicator 62. On the viewer side, the instruction unit 62 is visually recognized by red, which is the color tone of the translucent hot stamp layer 66 itself, and as a result, the instruction unit 62 and the display unit 21 as if the light source 130 is turned on. It is visually recognized as extending to the center point C1 of the display surface.
