  The first illumination display unit 27 has a non-transparent and achromatic white light passage part that forms the front side member 21, and the second illumination display unit 28 has a chromatic color that forms the colored region 23. It has a certain green light passage. Therefore, the illuminance when the same amount of illumination light is applied from the rear to the first illumination display unit 27 and the second illumination display unit 28 is determined by the first illumination display unit 27. Higher than 28.

  The first illumination display unit 27 is located opposite to the front of the first light passage unit 25 formed on the back side member 22, and the second illumination display unit 28 is formed on the back side member 22. It is located in front of the second light passage part 26.

  The operation body 20 is divided into a front-side member 21 and a back-side member 22 through a two-color molding process, and an opening for forming a second light passage portion 26 is formed in the back-side member 22. However, no extreme difference in the wall thickness dimension occurs in the front member 21. Therefore, the front surface 21a of the front side member 21 is not distorted by so-called sink marks during molding. Further, since the lock piece 22c and the positioning protrusion 22e are formed integrally with the back side member 22, the front side member 21 is not distorted due to sink marks at the time of molding in front of the lock piece 22c and the positioning protrusion 22e.

  Therefore, the front surface 21a of the front side member 21 has a smooth projecting curved surface, no irregular surface is formed on the front surface 21a, and the appearance is improved.

  As shown in FIG. 1, the operating body 20 includes a holding ring 29 that holds the front side member 21 and the back side member 22. The holding ring 29 is located on the outer periphery of the peripheral side portion 21 b of the front side member 21 and is fixed to both the front side member 21 and the back side member 22. The front surface of the retaining ring 29 is colored to form a decorative surface 29a. The rear portion of the holding ring 29 is a cylindrical portion 29 b, and this cylindrical portion 29 b faces the lock piece 22 c formed on the back side member 22.

  When the operating body 20 is combined with the advance / retreat member 6, the front end 6b of the advance / retreat member 6 is inserted into the gap between the lock piece 22c and the holding ring 29, and integrally protrudes from the inner peripheral surface of the front end 6b.

  In the operating device 1 shown in FIG. 1, a rotating operation body 31 is provided between the outer periphery of the operation body 20 and the outer case 5. When this rotating operation body 31 is rotated, a rotary encoder (not shown) operates and a rotation operation signal can be input.

Next, the illumination operation of the controller device 1 will be described.
As shown in FIG. 1, a light emitting member 32 is provided on the front surface 3 a of the support substrate 3. The light emitting member 32 is formed of a light emitting diode or the like. White light is emitted from the light emitting member 32. This light passes through the inside of the hole 12a formed in the movable part 12 of the repulsive elastic member 11, passes through the intermediate wall 6d of the advance / retreat member 6 formed of a transparent synthetic resin material, and is operated from the rear. 20 is given.

  A part of the light beam L <b> 1 emitted from the light emitting member 32 is given to the first light passage portion 25 of the back side member 22 of the operating body 20. Since the semi-transparent colored synthetic resin material constituting the back side member 22 exists in the first light passage portion 25, the light flux L <b> 1 is transmitted through the first light passage portion 25 so that the amount of light is reduced. The light is attenuated and further transmitted through the semitransparent colored synthetic resin layer constituting the front side member 21, and is given to the first illumination display unit 27. In the first illumination display unit 27, the letters “VOL” shown in FIG. 3A are displayed in white by the light beam L1.

  Another part of the light beam L2 emitted from the light emitting member 32 passes through the second light passage portion 26 of the back side member 22 and is given to the second illumination display portion 28 of the front side member 21. Since the second light passage portion 26 is an opening, the light beam L2 is directly given to the front-side member 21 and transmitted therethrough to illuminate the second illumination display portion 28. In the second illumination display unit 28, the symbol shown in FIG. 3 is illuminated with the hue of the colored region 23. In this embodiment, the second illumination display unit 28 is illuminated in green.

  The illuminance when the same amount of illumination light is applied from the rear to the first illumination display unit 27 and the second illumination display unit 28 is such that the first illumination display unit 27 uses the second illumination display unit 28. Is also expensive. However, since the light transmittance of the back side member 22 is higher in the second light passage portion 26 than in the first light passage portion 25, the light transmittance of the second member 22 is larger than the light amount given to the first illumination display portion 27. The amount of light given to the illuminated display unit 28 increases. As a result, it is possible to reduce the difference in illuminance or brightness when viewing the white display on the first illumination display unit 27 and the green display on the second illumination display unit 28.

  In addition, since the front side member 21 is formed with a substantially uniform thickness, the front surface 21a having the first illumination display portion 27 and the second illumination display portion 28 may be distorted due to sink marks during molding. There is no appearance.

  Hereinafter, other embodiments of the present invention will be described. In each of the embodiments and the first embodiment shown in FIG. 1 to FIG.

The light diffusing unit 125 a is configured by forming fine irregularities on the rear surface of the back member 122. Since a part of the light beam L1 from the rear is diffused by the light diffusing unit 125a and the light incident on the back side member 122 is suppressed, the amount of light passing through the first light passing unit 125 of the light beam L1 is limited. can do.

  The second light passage portion 126 of the back side member 122 does not penetrate forward and backward, and is formed thinner than the first light passage portion 125. By changing the thickness of the second light passage portion 126, it is possible to adjust the amount of light given to the second illumination display portion 28.

A light diffusion portion 207a is formed on the surface. Further, on the line connecting the light emitting member 32 and the second light passage portion 26, the partial intermediate wall 207 does not exist and the opening 208 exists.

  In the operating device 201 shown in FIG. 5, the light beam L <b> 1 emitted from the light emitting member 32 is diffused by the light diffusing unit 207 a of the partial intermediate wall 207, and the amount of light is reduced before being given to the first light passing unit 25. On the other hand, the light beam L2 emitted from the light emitting member 32 passes through the opening 208 and is given to the second light passage 26 without being blocked.

  By forming the light diffusion portion 207a and the opening 208 behind the back side member 22, the amount of light applied to the first illumination display portion 27 of the front side member 21 can be further suppressed, and the first illumination display portion The difference between the illuminance at 27 and the illuminance at the second illumination display unit 28 can be reduced.
