Abstract

<P>PROBLEM TO BE SOLVED: To provide an illuminator capable of performing the simultaneous radiation of a plurality of colors for attaining a variable effect. <P>SOLUTION: This illuminator comprises a base plate 4 having a plurality of light sources 1..., 2..., 3... light emitting diodes, or the like, mounted on it; and a light guiding plate 6 mounted in opposition to the base plate 4 and formed with a window hole 5. An end part of the light guiding plate 6 is bent toward the base plate 4. Light from a part of the light sources 1..., 3... is guided to an end surface of a bent part 7. The light is radiated in a frame shape around the window hole 5 (a light radiating part 8) at a front side. Light 9 of the other light sources 2 passes through the window hole 5. In addition, the light guiding plate 6 has a light lead-in section 10 and a part 11 other than a frame-like light radiating part 8 operated as an untransmissive section. The light guiding plate 6 is formed with a transparent acrylic resin, or the like, and the light lead-in section 10 forms a recess where the light sources 1..., 3... are stored. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device suitable for a gaming machine such as a slot machine.

[0002]

2. Description of the Related Art In a gaming machine such as a slot machine, an illuminating device is provided inside a rotating drum on which numbers and the like are printed.

[0003]

However, in this type of illumination device, although the illumination color can be changed, only uniform illumination light is emitted and the change is scarce. Therefore, in view of such problems to be solved, it is an object of the present invention to provide a lighting device having a change capable of simultaneously emitting a plurality of colors.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described, but it is merely an exemplary embodiment adopted based on the present invention, and the present invention is based on matters peculiar to the embodiment. However, the technical scope of the present invention should be determined based on the matters shown in the claims and the matters substantially equivalent to the matters.

In the illustrated embodiment, a substrate 4 on which a plurality of light sources 1 ..., 2 ..., 3 composed of light emitting diodes and the like are mounted, and a window hole 5 formed so as to face the substrate 4 are formed. A light guide plate 6, and the end portion of the light guide plate 6 is the substrate 4
, 3 ... Of the light sources are introduced into the end face of the bent portion 7, and the window hole 5 is bent.
Is a lighting device in which light in the form of a frame is emitted to the front (light emitting portion 8) around the periphery of the window, and the light 9 of the other two of the light sources passes through the window hole 5. Further, the light guide plate 6 uses a portion 11 other than the light introducing portion 10 and the frame-shaped light emitting portion 8 as a light non-transmissive portion. The light guide plate 6 is formed of a transparent acrylic resin or the like, and the light introducing portion 10 has a notch shape in which the light sources 1, ... Reference numeral 12 is a semi-transparent rotatable drum having numbers printed on its surface.

More specifically, on the rear surface of the light emitting portion 8 of the light guide plate 6, a large number of fine concave or convex stripes 21 are formed finely in the vertical and horizontal directions, and the light introduced into the light guide plate 6 is directed to the front surface. It is designed to be able to emit diffuse reflection. Light source 1 ...
As 2 ..., 3 ..., a light emitting diode capable of emitting variable colors by a control circuit is suitable.

According to the present embodiment, the front surface of the light guide plate 6 can emit color light in a frame shape, and the color of the light sources 2 ... Can be emitted to the front surface through the window hole 5 of the light guide plate 6. You can enjoy interesting luminescence by changing the luminescent color with.

Claims (2)

[Claims] 1. A substrate having a plurality of light sources mounted thereon, and a light guide plate provided facing the substrate and having a window hole formed therein,
An end portion of the light guide plate is bent toward the substrate, and a part of the light of the light source is introduced to the end surface of the bent portion, and the light forms a frame shape around the window hole to form a front surface. The illumination device that is emitted to the window and allows the other light of the light source to pass through the window. 2. The illumination device according to claim 1, wherein the light guide plate has a portion other than the light introducing portion and the frame-shaped light emitting portion as a light non-transmissive portion.
