Each drawing shows the first embodiment of the present invention. FIG. 1 is a conceptual cross-sectional view of a principal part of a curtain plate of a gaming machine island according to a first embodiment of the present invention. FIG.
It is a front view of a gaming machine island similarly. FIG. 3 is a sectional view of a main part of a curtain plate of the gaming machine island. FIG. 4 is a perspective view of the curtain plate of the gaming machine island.

As shown in FIG. 1 and FIG.
Numeral 0 is configured by arranging a plurality of gaming machines 12 that are pachinko machines. In the center of the gaming machine island 10 in the island longitudinal direction, a replenishing machine 14 as a lifting and polishing device is disposed, and for transporting a game medium as a pachinko ball from the upper part of the replenishing machine 14 to each gaming machine 12. Supply gutter 15 extends to the island end.

The upper front surface of the gaming machine island 10 is constituted by a curtain plate 20 as an exterior product. The curtain plate 20 includes the outer panel 2
1, an inner panel 22, and a sound absorbing member 26.

The outer panel 21 is formed in a U-shaped cross section by a resin material, and forms the surface of the curtain plate 20. The inner panel 22 is made of a perforated metal or a wire mesh, and has a large number of insertion holes 23 formed therein.

The outer panel 21 and the inner panel 22 are joined together from both front and back sides to form a housing space 25 having a substantially rectangular cross section which is closed from both front and back sides. End member (both not shown)
Is blocked by Therefore, the insertion opening 23 of the inner panel 22 communicates with the back side and the inside of the storage space 25. A supply gutter 15 is extended behind the inner panel 22.

A sound absorbing member 26 is packed in the housing space 25. The sound absorbing member 26 is formed in a sheet shape having a thickness of 40 mm, and is adhered along the inner surface of the inner panel 22. Thereby, the sound absorbing member 26 covers the insertion opening 23 from inside the accommodation space 25.

As shown in FIG. 5, the sound absorbing member 26 may be made thinner, and the intermediate panel 31 may be superposed on the thinner sound absorbing member 26. In this case, the intermediate panel 31 is formed in a plate shape, and is also superposed on the sheet-shaped sound absorbing member 26 from inside the accommodation space 25.

As shown in FIGS. 3 and 4, a more specific configuration of the curtain plate 20 is such that the upper edge and the lower edge of the base panel 41 (which may be the intermediate panel 31) are
The upper and lower edges of the inner panel 22 are screwed to the rail member 42 in the V-shaped cross-sectional groove 2. An illumination lamp 43 is supported on the base panel 41. The outer panel 21 is curved to the front side, and the outer panel 2
A concave portion 21a is formed in the upper edge portion and the lower edge portion of the rail member 1. The concave portion 21a is engaged with the latching projection 42a of the rail member 42.

A sheet-like sound absorbing member 26 having a thickness of 40 mm is packed between the inner panel 22 and the base panel 41. The surface of the sound absorbing member 26 on the base panel 41 side is adhered to the base panel 41 with double-sided tape. For the sound absorbing member 26, a porous sound absorbing material is used. The sound absorbing material is
Among fibers made of glass or the like, formed into a cotton-like or board-like shape, and made of a foamed polymer material such as glass wool, rock wool, or polyurethane, those having continuous cells in which bubbles are connected to each other.

[0024] These sound absorbing materials are characterized by having many small gaps that are continuous in a complicated manner between fibers and many continuous bubbles. When sound enters the porous material, the sound enters small gaps in the material, so that air in the gap repeatedly compresses and expands according to the frequency of the sound, and the sound is lost due to energy loss at that time.

In this embodiment, by using a polyurethane foam, a porous material can be obtained, and sound can be well absorbed. The sound absorbing member 26 is not limited to urethane foam, but may be any material that converts sound energy into kinetic energy of the material and absorbs sound.

The surface of the sound absorbing member 26 on the side of the inner panel 22 is formed in a wedge shape. Thereby, even if the area is small, the surface area can be increased, the sound refraction can be effectively generated, and a large sound absorbing effect can be exhibited. The entire curtain plate 20 is supported by the hinge member 18 on the gaming machine island 10 side so as to be deployable to the front side.

A supply gutter 15 is provided on the back side of the curtain plate 20 of the gaming machine island 10 (on the back side of the inner panel 22), and a game medium such as a pachinko ball flows through the supply gutter 15. The sound when the game media flows flows through the insertion opening 23 of the inner panel 22 and the accommodation space 25.
Get inside. At this time, since the inner panel 22 is made of a perforated metal or a wire mesh having a large number of insertion holes, the sound generated on the back side of the curtain plate 20 easily enters the accommodation space through the insertion holes 23.

The sound passing through the insertion opening 23 is absorbed by the sound absorbing member 26 filled in the housing space 25. Since the sound absorbing member 26 formed in a sheet shape is adhered along the inner surface of the inner panel 22 so as to close the insertion port 23, the sound passing through the insertion port 23 is reflected on the inner surface of the outer panel 21. The sound is absorbed by the sound absorbing member 26 without leaking out of the storage space 25. Further, since the outer space 21 and the inner panel 22 close the housing space 25 from both sides, the sound does not leak from the front side of the housing space 25, that is, from the upper front surface of the gaming machine island 10 to the front surface. .

As shown in FIG. 4, when a thin sound absorbing member 26 with an intermediate panel 31 superposed thereon is used, even if the sound absorbing member 26 is slightly thinner and its sound absorbing performance is low, The sound that has entered the interior of the accommodation space 25 is finally blocked by the intermediate panel 31 and does not leak outside the accommodation space 25.

By mounting the main curtain plate 20 on the upper front surface of the gaming machine island 10, the sound absorbing member 26 is attached to about 15% of the total area inside the island, thereby reducing the noise level inside the island by about 5 dB. be able to.

This makes it possible to reduce the level of noise leaking outside the island. In addition, for high frequencies of 2 kHz or more, noise reduction of about 10 dB becomes possible,
Particularly unpleasant sounds can be reduced.

Further, by attaching the sound absorbing member 26 to the main curtain plate 20, the noise level can be reduced by 1 dB or more. Thereby, the sound leaking out of the island can be reduced. For high frequencies of 2 kHz or more, 1
There is an improvement in sound insulation characteristics of 0 dB or more, and particularly unpleasant sounds can be reduced.

Next, a second embodiment of the present invention will be described. In the present embodiment, a sound absorbing member 126 is provided on a waist plate 120 which is an exterior component constituting a lower front surface of the gaming machine island 10. With such a configuration,
The sound when a game medium such as a pachinko ball flows through a game medium collection gutter or the like disposed on the back side of the waist plate 120 can obtain a sound absorbing effect in the same manner as the curtain plate 20.

The configuration of the waist plate 120 according to the second embodiment of the present invention will be specifically described with reference to FIGS. FIG. 6 is a cross-sectional view of a main part of a waist plate 120 according to the second embodiment of the present invention.

The waist plate 120 has an outer panel 121 and an inner panel 122 joined from both front and back sides to form a storage space 125 closed from both front and back sides. A number of reinforcing frames 16 extend from the inner surface of the outer panel 121 to the inner surface of the inner panel 122, and the number of reinforcing frames 16 divide the accommodation space 125 into a number of accommodation spaces in the vertical direction. The large number of accommodation spaces are filled with sound absorbing members 126.

In the above-described embodiment, the curtain plate 20 and the waist plate 120 are shown as exterior components constituting the outer peripheral surface of the gaming machine island 10, and the sound absorbing members 26 and 126 are provided on these. In addition to the curtain plate 20 and the waist plate 120, a sound absorbing member 26 may be provided on a top cover forming the upper surface of the gaming machine island 10 or a cover of a lifting polishing device as an exterior component forming the outer peripheral surface of the gaming machine island 10. May be provided. Thereby, the sound absorbing effect can be further improved.

Next, based on FIGS. 9 to 15, the results of a specific investigation of the sound absorbing performance and the like of the curtain plate and the waist plate according to the embodiment of the present invention will be described. FIG. 9 is a diagram showing measurement points on the gaming machine island according to the present embodiment.

FIGS. 10 to 15 are relationship diagrams showing the relationship between the frequency and the noise level based on the measurement result of the noise level.

In FIG. 10 to FIG. 15, “before countermeasures” means a countermeasure for reducing noise in the conventional product (change of material of overflow branch metal fittings, strengthening of sound insulation, attaching a PVC sheet inside the lower rail,
This is a gaming machine island with measures such as changing the tank material and strengthening sound insulation. "Countermeasure 1" is a sound absorbing member (4 cm thick) stuck inside the top cover (range from the center of the island to about 3.4 m to the left and about 4.2 m to the right). "Measures 2"
In addition to the measure 1, a sound absorbing member (a range from the island end to the island end on both sides of the island) is attached to the curtain plate 20 and the waist plate 120. In the measure 1, the area covered by the sound absorbing member 26
6% and 42% for Measure 2.

The "measure 3" is a measure in which, in addition to the measure 2, the upper and lower sides of the curtain plate are covered (the range from the island end to the island end on both island sides). "Measure 4" means, in addition to Measure 3, the gap between the baseboards is covered with an aluminum L angle (3.4 left from the center of the island)
m, range up to 4.2 m on the right). The “measure 5” is a measure in which the circumference of the premium ball counter is reinforced in addition to the measure 4.

The measuring method is as follows. The microphone of the precision sound level meter is installed at the following location, and the AC output is recorded on the DAT. D
Play the AT tape and use the real-time analyzer to
Find the equivalent noise level for a second.

(A) The positions of the microphones for measuring the effect of the sound absorbing member are, for each measure, at the center of the island (indicated as center or front), 3.4 m left and 4.2 m right therefrom. Up and down 50 cm from the island surface (1 floor above the floor)
60 cm and 20 cm).

(B) The microphone position at the time of measuring the noise level due to the difference in the volume setting of the speakers of the pachinko machine and the difference in the glass setting is 5 mm from the center of the pachinko machine.
It is a position at a height of about 120 cm, which is 0 cm away.

The sound absorbing members 26, 1 are attached to the curtain plate 20 and the waist plate 120.
By attaching 26, the noise level is reduced by about 2 dB. The reason why the noise reduction amount is small when the sound absorbing member is attached to the top cover is that the area is small, not because the effect is small.

Further, the noise level was reduced by about 2 dB by covering the upper and lower sides of the curtain plate 20. By blocking the gap between the baseboards, the noise level in the 5-8 kHz band is reduced by about 2 dB at the sitting position.

The sound insulation volume of the waist plate 120 is estimated to be about 17 dB. In the unmeasured game machine island 10, when the speaker is ON, the noise level differs depending on whether the glass is one, two, or double glass for the same speaker level. It is not allowed. Mostly sounds from speakers. In particular, the sound pressure at 1 kHz or less and 3 to 4 kHz is very large.

In the measurement on the gaming machine island 10 where no measures are taken, when the speaker is turned off, the double glass is reduced by about 2 dB at 4 to 5 kHz as compared with two glasses, but the frequency is 2 kHz.
In the following, it is increased by about 2 dB. In overall, both are no different from 80 to 81 dB, but are considered to be called low noise glass in order to reduce high frequency components.

Furthermore, by arranging similar parts around the branch fittings, distribution rails, and guide rails of the lifting and polishing apparatus, the noise level can be reduced by 5 dB or more.
