The second diffusion film and the first diffusion film are spaced apart from each other by a predetermined distance. The second diffusion film is formed of a material having a higher light transmittance and lower diffusibility than the first diffusion film. The light guide is inserted into the through hole of the main housing, and guides light from the light source installed on the back side of the main housing in the front direction.

  In this configuration, if the light from the light source is weak, a light emission shape substantially the same as the opening shape of the through hole appears on the front surface. However, if the light from the light source is strong, a light emission shape composed of a strong light emitting portion similar to the shape of the through hole and a weak light emitting portion that surrounds the strong light emitting portion and appears to diffuse radially appears in the front. That is, different light emission shapes can be realized only by the intensity of light.

Also, the main housing in Lee Rumi Nation mechanism of the present invention, through holes are formed.

  In this configuration, since a plurality of through holes are formed, a different light emission shape can be realized for each position of the through hole by performing control such as changing the intensity for each light passing through the through hole. Thereby, various light emission patterns are realizable.

Further, a plurality of through-holes in the i Rumi Nation mechanism of the present invention, the opening shape is formed by a plurality of types.

  In this configuration, even when light of the same intensity is incident, the light emission shape is different for each type of penetration. Thereby, more various light emission patterns can be realized.

Further, the plurality of through-holes in the i Rumi Nation mechanism of the present invention, a through hole lightguide has been inserted, and a through hole lightguide is not inserted there.

  In this configuration, different light emission shapes can be realized between the through hole into which the light guide is not inserted and the through hole into which the light guide is inserted. Thereby, more various light emission patterns can be realized.

The plurality of light guide in Lee Rumi Nation mechanism of the present invention is formed of a plurality of types of shapes.

  In this configuration, even if light of the same intensity is incident, the light emission shape is different for different types of light guides. Thereby, more various light emission patterns can be realized.

Further, the front side wall surface of the main housing in Lee Rumi Nation mechanism of the invention includes a plurality of regions formed by recesses of different depths.

  In this configuration, the distance between the front end face of the through hole and the first diffusion plate can be set in a plurality of types. Thereby, more various light emission patterns can be realized.

Further, the first diffusion film and the second diffusing film in Lee Rumi Nation mechanism of the present invention, is installed to each flat surface facing the light transmitting plate with no diffusion to light.

  In this structure, even if the 1st diffusion film and the 2nd diffusion film are very thin, it can implement | achieve easily installing in parallel at predetermined intervals with a translucent board.

Further, on the front of the second diffusion film in Lee Rumi Nation mechanism of the present invention, the semi-transmissive reflective decorative plate is installed.

  In this configuration, by providing the decorative plate, it is possible to make it difficult for the user to visually recognize the internal through hole and the light guide plate. Thereby, a more attractive front wall can be realized. Further, if the decorative plate is appropriately provided with diffusibility, more various light emission patterns can be realized.

According to the present invention, it is not necessary to perform replacement of parts, with a relatively simple structure, it is possible to realize a multi-colors light emission shape.

  The main support plate 701 is formed with an area substantially coinciding with the formation region of the half through-holes 203 and 803 along the longitudinal direction of the above-described through-holes 203 and 803.

  On the front side of the main support plate 701, a plurality of front side light guide portions 702 each having a substantially quadrangular prism shape are formed. The plurality of front-side light guides 702 are formed at the same intervals as the through holes 203. The plurality of front-side light guides 702 are formed in a size that can be inserted into the through hole 203. The height (length along the front direction) of the plurality of front-side light guides 702 is formed to be the same as the depth of the through hole 203. The plurality of front-side light guides 702 are formed so that the cross-sectional area decreases as the distance from the main support plate 701 increases.

At this time, the back side main housing 80 is disposed so that the corresponding back side light guide portions 703 are inserted into the respective through holes 803 and the main support plate 701 is accommodated in the recesses 802. After such a composite is configured, the front main housing 20 and the back main housing 80 are fixed with screws or the like. Thereby, the housing | casing with the light guide function by a some through-hole and a light guide is formed.

  A flat diffusion plate 30 is disposed on the front side of the main body 201 of the front side main housing 20 so as to be housed in the recess 202.

  The diffusing plate 30 includes a translucent plate 300 having high translucency and not diffusibility. A first diffusion film 301 is disposed on the flat plate surface of the translucent plate 300 on the front main housing 20 side. A second diffusion film 302 is disposed on the surface of the translucent plate 300 that faces the surface on which the first diffusion film 301 is disposed. The first diffusion film 301 and the second diffusion film 302 may have a structure that is adhered to the respective flat plate surfaces of the translucent plate 300 or a structure that is printed. By setting it as such a structure, even if the 1st diffusion film 301 and the 2nd diffusion film 302 are very thin structures, it can arrange | position in the state holding the distance between these films. Further, the distance from other parts, for example, the front main housing 20 can also be made uniform on the surface.

  The first diffusion film 301 is made of a material having low translucency and high diffusibility. Here, diffusivity means that light incident from one main surface travels straight without being refracted, does not exit from the other main surface, repeats catadioptric refraction within the diffusion plate, and has an area of the exit surface rather than the entrance surface. Shows the property of widening. Low diffusivity means that the area of the exit surface is the same or less wide than the incident surface, and high diffusibility means that the area of the exit surface is wider than the incident surface. Indicates.

  The second diffusion film 302 is made of a material having a high translucency and low diffusibility compared to the first diffusion film 301.

  A front side fixing member 40 is disposed on the front side of the diffusion plate 30, that is, on the side opposite to the front side main housing 20 of the diffusion plate 30. The front-side fixing member 40 includes a rectangular main body 401 whose outer shape when viewed from the front is substantially the same as that of the front-side main housing 20 or is a predetermined amount wider.

  A through-hole 402 having a shape smaller than the outer shape of the diffuser plate 30 is formed in the main body 401 of the front-side fixing member 40, including the above-described formation region of the through-hole 203. Front side fixing for the front side of the main body 401, that is, on the side opposite to the front side main housing 20, includes a through hole 402 when viewed from the front side and substantially matches the outer shape of the light-transmitting decorative board 50. A recess 403 is formed. Also, a decorative plate fixing recess that includes a through hole 402 on the front side of the main body 401, that is, on the opposite side to the front main housing 20 and substantially matches the outer shape of the decorative plate 60. 404 is formed.

  A translucent decorative board 50 is disposed on the front side of the front side fixing member 40, that is, on the opposite side to the front side main housing 20. At this time, the translucent decorative board 50 is disposed so as to be housed in the front-side fixing recess 403 of the front-side fixing member 40.

  A decorative plate 60 is disposed on the front side of the translucent decorative plate 50, that is, on the opposite side to the front-side fixing recess 403. At this time, the decorative plate 60 is disposed so as to be accommodated in the decorative plate fixing recess 404 of the front surface side fixing member 40.

  The decorative plate 60 has a so-called semi-transparent mirror structure having translucency and reflectivity. Thereby, the light from the back side is transmitted to the front side, and the back side is not visible even when viewed from the front side.

  When the illumination mechanism component 10 having such a structure is viewed from the front side of the illumination mechanism component 10, the light emission shape shown in FIG. 8 is obtained at portions corresponding to the through holes 203 and 208. FIG. 8A is a diagram schematically showing a light emission shape when the light from the light source is strong, and FIG. 8B is a diagram schematically showing a light emission shape when the light from the light source is weak.

  When the light from the light source is strong, as shown in FIG. 8 (A), a substantially circular high-emission area LmH that is substantially the same as the front shape of the through-hole 203 and the front-side light guide portion 702 is substantially circular and radial. The light emission shape has a low light emission region LmL in which the luminance decreases as the distance from the center increases.

  On the other hand, when the light from the light source is weak, as shown in FIG. 8B, the light emission shape has a substantially square light emission region LmM that is substantially the same as the front shape of the through hole 203 and the front light guide portion 702.

  Such a phenomenon is guided through the light guide 70 and the through holes 203 and 208, the first diffusion film 301 having low translucency and high diffusibility, and the second diffusion having high translucency and low diffusivity. This is because the light is guided to the front side in the order of the film 302.

  Specifically, the light emitted through the through holes 203 and 208 and the light guide 70 is guided by the front light guide 702 of the light guide 70, and the front light guide 702 and the through holes 203 The light is incident on the first diffusion film 301 with the light emission shape having substantially the same front shape.

  When the light emission intensity of the light source is strong, the first diffusion sheet 301 emits light while being diffracted while being diffracted so as to spread from the front shape of the front light guide 702, and enters the second diffusion sheet 302. At this time, the light intensity is high in the region overlapping the front light guide unit 702 when viewed from the front, and the light intensity is weak in the peripheral area. However, since the overall light intensity is strong, the light incident from the first diffusion sheet 301 is hardly attenuated by the second diffusion sheet 302 having high translucency and low diffusibility, and the incident light The light is emitted to the front side in substantially the same shape as the shape. As a result, a light emission pattern as shown in FIG.

  When the light emission intensity of the light source is weak, the intensity of the light diffused by the first diffusion film 301 is further reduced. Therefore, even if the light is incident on the second diffusion film 302, the light cannot be transmitted through the second diffusion film 302 and is not emitted to the front side. As a result, the emitted light has substantially the same front shape as the front light guide 702 and the through hole 203 of the light guide 70.

  Thus, by using the configuration of the present embodiment, various light emission shapes can be realized only by adjusting the light amount of the light source.

  In this case, the light source may be a point light source such as an LED disposed at each position of the through holes 203 and 208. As a result, more diverse light emission shapes can be realized by controlling the amount of light for each point light source.

  In addition, as described above, the through hole 203 and the front light guide portion 702 may have a plurality of types, the front end portion of the through hole 203 and the first diffusion plate 30 may have a plurality of types, or may be guided. By disposing the light body 70 only in part of the through holes 203 and 208, different light emission shapes are obtained, and thus various light emission shapes can be realized.

  In the above description, the example in which the light guide 70 is formed only on the half surface of the formation region of the through holes 203 and 803 has been shown, but the light guide 70 may be formed over the entire surface. Moreover, you may form all the front side light guide parts 702 by the same shape.

  In the above description, the example using the transflective decorative plate 60 has been described. However, the decorative plate 60 may be further provided with diffusibility.

  In the above description, the number of through-holes 203 and 208 is 60, but other numbers may be used. Moreover, although the case where the shape of the through holes 203 and 208 when viewed from the front is a substantially rectangular shape is shown, other polygons such as a triangle may be used.

  In the above-described embodiment, the illumination mechanism component mounted on the karaoke apparatus has been described as an example. However, the illumination mechanism component may be installed on a surface visible to the user in other installation-type gaming machines or electronic devices.

  Moreover, although the illumination mechanism component of this embodiment is a structure retrofitted to a front panel, you may equip the front panel itself with the structure of the said illumination mechanism.
