Description

  The present invention relates to a translucent display mechanism attached to an operation panel of various electronic devices, a console box of an automobile, or the like.

  2. Description of the Related Art Conventionally, operation knobs for various operations are installed on the exterior surface of, for example, a console box of an automobile, and various electric parts of the automobile are operated by operating these operation knobs. The exterior surface and operation knob are provided with a translucent display mechanism that illuminates the display portion such as characters and figures provided at these predetermined positions by illuminating them from the back side at night. . In this kind of translucent display mechanism, there is a structure in which the color of the display unit displayed in the daytime is different from the color of the display unit displayed by illumination at nighttime.

  This type of translucent display mechanism is a colorless and transparent synthetic resin light guide member 530 on the back side of a colorless and transparent synthetic resin outer case 510, such as a translucent display mechanism 500 shown in FIG. Further, a light emitting means 550 such as a light emitting diode is disposed on the back side thereof, and on the other hand, a first color layer 511 formed by applying, for example, a green paint on the surface of the exterior case 510, and the surface of the first color layer 511 For example, a black paint having a second color layer 513 formed by applying, for example, a gray paint and a display unit 517 that covers the surface of the second color layer 513 and exposes the second color layer 513 is applied. The third color layer 515 is formed.

  For example, if the light emitting means 550 is turned off in the daytime or the like, gray which is the color of the second color layer 513 is displayed on the display unit 517 from the outside. On the other hand, when the light emitting means 550 is turned on at night, for example, the first color layer 511 is illuminated from the back side of the second color layer 513, so that the green color of the first color layer 511 passes through the second color layer 513. It appears on the surface side of 517, and the color of the display portion 517 is displayed in green.

  By the way, in the translucent display mechanism 500, the second color layer 513 needs to be formed thin enough to allow green light to pass through when illuminated from the back side, but the second color layer 513 is required. Since the first color layer 511 is formed directly on the back side of the first color layer 511, the color (green) of the first color layer 511 passes through the second color layer 513 even if the light emitting means 550 is turned off depending on the amount of light. In some cases, the surface side can be seen through. That is, for example, the display unit 517 may appear slightly green even during the daytime.

  As another translucent display mechanism for reducing the above problem, for example, a translucent display mechanism 600 shown in FIG. 7, the exterior case 610 itself is made of a green transparent (that is, colored and transparent) synthetic resin, and its rear surface. A transparent light guide member 630 made of a colorless and transparent synthetic resin is arranged on the side, and a light emitting means 650 such as a light emitting diode is arranged on the back side of the light guide member 630, and a gray paint is applied to the surface of the outer case 610, for example. The structure which forms the 1st color layer 611 and the 2nd color layer 615 which apply | coats the black paint which provided the display part 617 which covers the surface of the 1st color layer 611 and exposes the 1st color layer 611, for example is formed. Conceivable.

  For example, if the light emitting unit 650 is turned off, gray which is the color of the first color layer 611 is displayed on the display unit 617 from the outside. On the other hand, when the light emitting means 650 is turned on, the color (green) of the exterior case 610 itself appears from the back side of the first color layer 611 through the first color layer 611 on the surface side of the display unit 617, and the color of the display unit 617 becomes green. Is displayed. With this configuration, the colored transparent exterior case 610 having a lighter color than the color of the first color layer 511 shown in FIG. 6 is installed on the back side of the first color layer 611. Is difficult to see through the surface side of the first color layer 611.

However, in this translucent display mechanism 600, since the colored transparent synthetic resin is directly installed on the back side of the thin first color layer 611 that transmits light, the light emitting means 650 is turned off depending on the amount of light. In addition, there is a possibility that the color (green) of the exterior case 610 installed on the back surface side of the first color layer 611 may be seen through, and a translucent display mechanism that hardly causes such a problem has been desired.
Japanese Utility Model Publication No. 4-37984

  The present invention has been made in view of the above points, and its purpose is that the color displayed on the display unit when the light emitting unit is turned on is not displayed on the display unit when the light emitting unit is turned off. Accordingly, it is an object of the present invention to provide a translucent display mechanism capable of clearly distinguishing the difference in color on the display unit when the light emitting means is turned on and off.

  The invention according to claim 1 of the present application is made of a transparent synthetic resin, and has a first color layer having translucency on the surface, covers the surface of the first color layer, blocks light transmission, and the first color layer. A transparent base material formed with a second color layer provided with a display portion exposing the layer, and a colored transparent synthetic resin, and disposed on the back side of the transparent base portion provided with the display portion. A colored transparent base material, and a light guide member that is disposed on the back side of the colored transparent base material and introduces light from the light emitting means to the colored transparent base material. The translucent display mechanism is characterized by the following.

  The invention according to claim 2 of the present application is the translucent display mechanism according to claim 1, wherein the number of display portions provided in the second color layer of the transparent base material is plural, Place the colored transparent substrate on the back side of the transparent substrate of the part where any display unit is provided, and on the back side of the transparent substrate of the part where the display unit on which no colored transparent substrate is arranged Is a translucent display mechanism characterized in that a light guide member is disposed directly opposite.

  According to invention of Claim 1, the transparent base material which gave the thin 1st color layer which lets light pass on the surface is installed, and the colored transparent base material different from the said transparent base material is installed in the back side Will be. With this arrangement, there is a thin air layer between the transparent base material having the first color layer and the colored transparent base material. Therefore, when the light emitting means is turned off, the light from the outside is reflected by this air layer and the colored transparent base The color of the material is not visible, and only the first color layer is visible. On the other hand, when the light emitting means is turned on, the light arranged on the back side passes through the colored transparent substrate, and further radiates to the outside through the transparent substrate and the transparent first color layer. Becomes clearly visible from the outside. This makes it possible to clearly distinguish the difference in color on the display unit between when the light emitting means is turned on and when it is turned off.

  According to the second aspect of the present invention, for any one of the plurality of display units, the color displayed on the display unit can be changed between when the light emitting element is turned on and when the light emitting element is turned off. The unit can be easily configured so that the display unit can be illuminated without changing its color.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a basic schematic configuration diagram of a translucent display mechanism 1 according to an embodiment of the present invention. As shown in the figure, the translucent display mechanism 1 includes a transparent base material (hereinafter referred to as “exterior case”) 40 formed by laminating a first color layer 10 and a second color layer 30 on the surface side, A colored transparent substrate 50 made of a transparent synthetic resin (green in this example), a light guide member 60 made of a transparent synthetic resin, and a light emitting means 70 are provided.

  The outer case 40 is formed by molding a colorless and transparent synthetic resin into a substantially flat plate shape. In this example, an acrylic resin is used as the synthetic resin material, but other various synthetic resin materials may be used.

  The first color layer 10 is formed by applying colored (light gray in this embodiment) paint to the surface of the outer case 40 by means such as spraying. Since the first color layer 10 has a thin coating thickness and a bright color, it transmits light to some extent, that is, has a light-transmitting property.

  The second color layer 30 is formed by applying a colored (black in this embodiment) paint to the surface of the first color layer 10 by means such as spraying. Since the second color layer 30 has a dark color, it is difficult to transmit light. That is, the second color layer 30 covers the surface of the first color layer 10 and blocks the transmission of light from the back side. A display unit 31 that exposes the first color layer 10 by notching the second color layer 30 is provided at a predetermined position of the second color layer 30. The display unit 31 is configured by cutting out shapes such as various symbols, numbers, and patterns. As a method for forming the display unit 31, after the second color layer 30 is applied to the entire surface of the first color layer 10, only the second color layer 30 is removed into the shape of the display unit 31 by laser light. Do. Of course, the display unit 31 may be formed by using various other methods such as, for example, applying the second color layer 30 after attaching a mask having the shape of the display unit 31 to the surface of the first color layer 10.

  The colored transparent base material 50 is transparent, but is formed by molding a colored (green) synthetic resin into a substantially flat plate shape. In this example, an acrylic resin is used as the synthetic resin material, but other various synthetic resin materials may be used. In other words, the colored transparent substrate 50 is a colored light guide (color filter). The colored transparent substrate 50 is disposed at least on the back side of the portion of the exterior case 40 where the display unit 31 is provided.

  The light guide member 60 is formed by molding a colorless and transparent synthetic resin into a predetermined shape. In this example, an acrylic resin is used as the synthetic resin material, but other various synthetic resin materials may be used. Light emitting means 70 for introducing light into the light guide member 60 is installed at a position facing a predetermined portion of the light guide member 60. The light guide member 60 is disposed on the back side of the colored transparent substrate 50 and introduces light from the light emitting means 70 into the colored transparent substrate 50.

  Although the light emitting means 70 uses a light emitting diode in this embodiment, light is guided to other light emitting means such as other light sources such as EL (electroluminescence) or another light source to the light guide member 60. Another light guide member to be introduced may be used.

  In the translucent display mechanism 1, when the light emitting means 70 is turned off in the daytime or the like, when the display unit 31 is viewed from the outside of the outer case 40 (left side in FIG. 1), the display unit 31 has a first color layer. Since 10 is exposed, the display unit 31 is displayed in light gray which is the color of the first color layer 10.

  On the other hand, when the light emitting means 70 is turned on at night or the like and the light is introduced into the light guide member 60, the introduced light is introduced into the exterior case 40 after passing through the colored transparent base material 50, and also transmitted through the first color layer 10. Then, it is emitted from the display unit 31 to the outside. Since this light becomes green light when passing through the colored transparent substrate 50, the light emitted from the display unit 31 to the outside also becomes green.

  According to the translucent display mechanism 1, as described above, the colorless and transparent exterior case 40 with the thin first color layer 10 that transmits light is provided on the surface, and the rear case is different from the exterior case 40. Since the colored transparent base material 50 of the member is installed, because of this arrangement, there is a thin air layer between the exterior case 40 having the first color layer 10 and the colored transparent base material 50, so the light emitting means 70 is turned off. Sometimes, light from the outside is reflected by this air layer, and the color of the colored transparent substrate 50 is not visible, and only the first color layer 10 is visible. On the other hand, when the light emitting means 70 is turned on, the light arranged on the back side is emitted to the outside through the colored transparent base material 50 and further through the exterior case 40 and the translucent first color layer 10. The color of the material 50 can be clearly seen from the outside. Thereby, the difference in color displayed on the display unit 31 when the light emitting means 70 is turned on and off can be clearly distinguished.
