recognized, a light diffusing agent etc. is mixed and translucent such as milky white The light
may be made of resin, and the light from the LED 14 is projected onto the frame 7 and appears
to be surface emitting, so that it is possible to obtain a lighting effect different from the
transparency that the LED 14 can view directly. Furthermore, in order to diffusely reflect the
irradiation light from the light emitting means 11, the surface is subjected to a light diffusion
process such as satin, emboss, or embossed, knurled, V-cut, etc., and diffused light when visible
light is reflected. To create an effect of light with a depth. Further, a decorative pattern may be
engraved on the frame 7 or colored in whole or in part to enhance the decorativeness.
[0029]

unit 12 so that the speaker unit 12 can be mounted to the mounting portion by one touch. At this
time, the LED 14 may be provided corresponding to the mounting base 21. By providing the
mounting base 21 on the frame 7 in this manner, the light emitted from the rear of the frame 7 is
diffused by the mounting base 21, and the speaker unit 12 can be made more excellent in
decorativeness. In particular, when the diaphragm 5 is made opaque, the light emitting portion
becomes wider by the mounting base 21, so that the decorative effect can be enhanced. In
addition, it may change to the securing piece 22 as an attachment means of the speaker unit 12,
and you may make it provide the through-hole of screw wearing.

that the partition areas 36 and the partition plates 35 are irradiated. A half mirror-shaped
reflecting plate 40 is provided on the back of the dividing area 36, and the irradiation light of the
dividing area light source 37a provided behind the reflecting plate 40 is reflected by the
reflection surface to brighten the entire dividing area 36. It is made to irradiate. Further, on both
side surfaces in the plate thickness direction of the partition plate 35, reflection processing for
reflecting the irradiation light of the partition plate light source 37b is performed. In the
embodiment, a reflective seal is attached. Therefore, the irradiation light of the light source 37b
for partition plates which entered from the end face of the partition plate 35 is not diffused to
the division area 36, and the outer peripheral surface of the partition plate 35 is irradiated, and
the light which entered the partition plate 35 by the edge effect It is clearly visible from the
player side. In addition, even if the light emission color of the light source 37b for the partition
plate is different from that of the speaker unit 12 or 12B, the light incident on the partition plate
35 does not leak to the partition region 36, so the partition region 36 can be clearly identified.
As a result, various decorative effects of the decorative portion 32 can be obtained and the stage

effect can be enhanced.

The speaker unit 12 has a hook 41 provided on the peripheral edge of the opening 44 as shown
in FIG. 12 and a flange 42 of the frame 7 through a light transmissive resin cover body 42a
having a small hole formed on the front side. Can be easily assembled in each partition area 36.
In the embodiment, the rear side of the speaker unit 12 is also protected by the cover body 42b
subjected to the reflection processing and the appearance is improved. At this time, the wires of
the speaker 1 and the light emitting means 11 are wound with a reflective tape so as not to be
noticeable, and are arranged in a groove formed on the lower surface of the partition plate 35
and guided to the rear of the base portion 33. Further, as shown in FIG. 12, the speaker unit 12B
is assembled to the decorative portion 32 by screwing a mounting boss portion 23c provided on
the rear case body 23b through a boss provided on the base portion 33 so as to protrude. At this
time, the wiring of the speaker unit 12B drawn out from the opening opened at the bottom of the
rear case body 23b is led as it is to the rear of the base portion 33, so the wiring does not stand
out and does not impair the decorativeness. The shape of the case body 23 of the speaker unit
12B may be changed in accordance with the decorative property of the decorative portion 32.
Further, the speaker unit 12B may also be attached and detached at one touch by a locking claw
or the like. In the speaker unit 12B, a part of the reflection plate 40 may be raised and attached
so as to be embedded in an opening formed in the raised portion.
[0041]
As described above, by providing the speaker unit 12, 12 B provided with the light emitting
means 11 in the decorative portion 32, various effects can be obtained by the combination of the
sound outputted from the speaker 1 and the light emission mode of the light emitting means 11.
Further, since the frame 7 of the speaker unit 12 or 12 B is formed of the light transmitting resin,
there is nothing to inhibit the irradiation of the LED 14, and the site where the speaker 1 is
located is not noticeable. The speaker unit 12, 12B can be used as a part of the design without
losing its appearance, and continuous illumination with high decorative effect is also possible,
and the pachinko gaming machine 100 can be made more rich in decorative effect.
[0042]
Further, as shown in FIG. 10, by providing the band-like light emitting part 45 on the game board
27 and providing the partition plate 35 of the decorative part 32 continuously in relation to the
10-05-2019
15
band-like light emitting part 45 Since the light emission mode of the partition plate 35 is viewed
as if light emission is continuous with the light emission of the strip-like light emitting portion 45
on the game board 27, it is possible to enhance the decoration effect and the rendering effect
over the entire game machine.

In the above embodiment, a pachinko game machine has been described as an example of a
game machine, but the present invention is also applicable to a ball ball game machine, an
arrange ball type game machine, and a slot-type game machine or the like be able to.
Further, the present invention is not limited to the contents described in the embodiments, and
various embodiments can be implemented without departing from the scope of the present
invention.
