Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a decorative panel 1 in the present embodiment, and FIG. 2 is a cross-sectional view taken along line II-II in FIG.

  As shown in FIG. 1, the decorative panel 1 is an operation panel for a car air conditioner, and has, for example, a circular switch SW used for temperature adjustment. This switch SW is a touch switch (touch panel) that functions to cause a car air conditioner body (not shown) to perform a predetermined operation in response to an approach operation or a contact operation from a user. In addition, the switch SW is provided with a name portion N indicating the content of the function at the center portion and an annular design portion D having a metallic luster at the peripheral portion.

Specifically, as shown in FIG. 2, the decorative panel 1 mainly includes a light guide member 2, a support member 3, a molded resin layer 4, a light shielding layer 5, and a front plate 6.
Among these, the light guide member 2 is formed in a flat plate shape orthogonal to the front-rear direction of the decorative panel 1, and an LED (light emitting diode) 6 is disposed to face the side end surface. The light guide member 2 guides the light emitted from the LED 6 and incident into the light guide member 2 from the side end face so as to be emitted from a portion of the front surface where the molded resin layer 4 is provided. Note that a plurality of LEDs 6 may be provided in parallel along the width direction of the light guide member 2 (the direction perpendicular to the plane of FIG. 2).

  The support member 3 is for supporting the molded resin layer 4 on the front surface of the light guide member 2. The support member 3 is formed in a plate shape having a hole in which the molded resin layer 4 is laminated. Is provided. The hole in which the molded resin layer 4 is laminated is formed in a truncated cone shape that narrows toward the rear, and the front surface of the light guide member 2 is exposed from the hole. The support member 3 may be configured integrally with the light guide member 2 as a part of the light guide member 2.

  The molded resin layer 4 is made of a resin having translucency, and is laminated on the front surface of the light guide member 2 in a hole formed in the support member 3. More specifically, the molding resin layer 4 is formed in a truncated cone shape that narrows toward the rear, and the peripheral surface thereof is a truncated cone-shaped inclined surface 4a. Further, the shape and size of the molded resin layer 4 in front view substantially correspond to the shape and size of the switch SW, and the shape and size of the inclined surface 4a in front view are the design of the switch SW. It substantially corresponds to the shape and size of the part D. In addition, the inclined surface 4a should just be the surface formed in the back side of the molding resin layer 4 inclining diagonally with respect to the front-back direction, and is not limited to a truncated conical surface shape.

  On the inclined surface 4a of the molded resin layer 4, a decorative film 8 having a metallic luster is insert-molded. The decorative film 8 is a multilayer laminate film in which polymer layers are laminated in a multilayered manner, and has a metallic luster despite being a non-metallic film containing no metal component. Examples of such a non-metallic film having a metallic gloss include a trade name “Picasus” (PICASUS) manufactured by Toray Industries, Inc. The decorative film 8 has a color tone that changes depending on the viewing direction.

  A decorative film 9 is insert-molded at the center of the front surface of the molded resin layer 4. As the decorative film 9, similarly to the decorative film 8, a non-metallic film (multilayer laminate film) having a metallic luster is used.

  Further, a transparent electrode sheet 10 is provided on the front surface of the support member 3, the molded resin layer 4, and the decorative film 9 over substantially the entire area thereof. The electrode sheet 10 functions as a capacitance type sensor, and has a detection unit (electrode unit) (not shown) that detects an approach operation or a contact operation from the front by the user in front of the molded resin layer 4. ing.

  The light shielding layer 5 is a black layer provided on the front surface of the electrode sheet 10, and more specifically, a black printed layer provided on the rear surface of the front plate 6. The light shielding layer 5 has a first light transmitting hole 5a and a second light transmitting hole 5b. Among these, the 1st translucent hole 5a is formed in the shape (alphabet "VOL") corresponding to the name part N of switch SW, and is provided in the front of the decoration film 9. FIG. On the other hand, the second light transmitting hole 5 b is formed in an annular shape corresponding to the design portion D of the switch SW, and is provided in front of the inclined surface 4 a of the molded resin layer 4.

  The front plate 6 is a translucent plate-like member, and is provided over the entire front surface of the light shielding layer 5 including the first light transmitting hole 5a and the second light transmitting hole 5b. However, more specifically, as described above, the light shielding layer 5 is printed on the rear surface of the front plate 6.

In the decorative panel 1 having the above configuration, when the LED 7 emits light, the light emitted from the LED 7 is guided through the light guide member 2 and enters the molded resin layer 4 from the rear surface.
Of the light incident on the molded resin layer 4, the light emitted forward from the front central portion of the molded resin layer 4 passes through the decorative film 9 and then passes through the first light transmitting hole 5 a of the light shielding layer 5. Only passes through the light shielding layer 5 and is irradiated forward from the front plate 6. As a result, the name portion N at the center of the switch SW emits light in the shape of the first light transmitting holes 5a of the light shielding layer 5 ("VOL" in the alphabet) while being accompanied by the metallic luster of the decorative film 9.

  A part of the light incident on the molding resin layer 4 is diffused widely toward the peripheral surface by the molding resin layer 4. After this light is reflected forward by the decorative film 8 provided on the inclined surface 4 a of the molded resin layer 4, only light passing through the second light transmitting holes 5 b of the light shielding layer 5 passes through the light shielding layer 5. Irradiated forward from the front plate 6. Thereby, the design part D of the switch SW peripheral part emits light in an annular shape that is the shape of the second light transmitting hole 5 b of the light shielding layer 5 while being accompanied by the metallic luster of the decorative film 8.

  Here, in the design part D, since the decorative film 8 having a metallic luster is provided on the inclined surface 4a inclined obliquely with respect to the front-rear direction, when the design part D is viewed from the front, Regardless of light emission or non-light emission, the decorative film 8 inclined obliquely with respect to the front-rear direction is visually recognized through the second light transmitting hole 5b. As a result, the decorative film 8 having a metallic luster is visually recognized with a sense of depth (three-dimensional effect), and the design portion D having a metallic luster becomes an appearance with a sense of depth.

  As described above, according to the decorative panel 1 of the present embodiment, the light emitted from the LED 7 enters the molded resin layer 4 through the light guide member 2, is diffused by the molded resin layer 4, and the molded resin layer 4. After being reflected forward by the decorative film 8 provided on the inclined surface 4 a, it is irradiated forward through the second light transmitting hole 5 b of the light shielding layer 5. At this time, the decorative film 8 that reflects light toward the second light transmitting hole 5b of the light shielding layer 5 is provided on the inclined surface 4a inclined obliquely with respect to the front-rear direction. When viewed from the front, the decorative film 8 inclined obliquely with respect to the front-rear direction is visually recognized through the second light transmitting hole 5b, and as a result, the decorative film 8 having metallic luster has a sense of depth ( It is visually recognized with a stereoscopic effect. Therefore, the appearance of the design portion D having the metallic luster can be given a sense of depth not only during non-light emission but also during light emission.

  Moreover, since the decorative film 8 is a non-metallic film containing no metal component, the decorative film 8 hardly affects the operation of the capacitive electrode sheet 10. Therefore, it is possible to provide the design portion D having a metallic luster without substantially affecting the sensitivity of the switch SW.
