2. Description of the Related Art As a basic configuration of a gaming machine represented by a pachinko machine and an arrange ball machine, as shown in FIG. 9 or 10, for example, in a pachinko machine P, an opening of an outer frame A as a rectangular frame body is provided. The middle frame B is attached to the front side so as to be attachable / detachable and openable / closable by using the connecting and supporting means and the locking means. Then, in the front side portion of the middle frame B, a side-opening front frame C having a glass door D and an upper bowl plate 60 are detachably and removably assembled, and the rear side of the upper bowl plate 60. An electric ball feeder is set in. In addition, the audio output device 57 is installed at a required position inside the middle frame B.
(Speaker or the like) is provided, and a lower ball plate E, a hitting ball launching device F, and the like are installed below the middle frame B. Furthermore,
A mechanism set board G and the like are provided on the back side of the middle frame B, and a game board J that constitutes a required game area I is attached / detached inside the front surface of a holding frame provided on the rear side of the middle frame B. It is set to be possible, and a symbol variable display device K is disposed in the approximate center of the game area I. Further, in the mechanism set board G, a main control means Q for controlling the entire pachinko machine, a symbol display control means R for controlling the variable symbol display device K, a voice control means 51, a lamp control means, a payout control means. , Various control means such as firing control means are arranged at predetermined parts respectively, and the various control means are electrically connected to the main control means Q. In response to a control command transmitted from the main control means Q. It is designed to control.

Then, a pachinko ball (game ball) stored in the upper ball plate 60 is shot in a game area I on the game board J by using the hitting ball launching device F, thereby playing a pachinko game. It is designed to be deployed. The middle frame for various game states (during the winning of a predetermined prize hole, when the variable display device K is activated, when special game conditions are established, when the winning device is activated, etc.) that are generated during the pachinko game. By outputting various sound effects and voices from the voice output device 57 arranged inside B, it is set to notify the player of the game state and to enhance the interest of the game.

Here, as shown in FIG. 11 or FIG. 12, the voice control means 51 for generating a sound signal for outputting various sound effects and voices from the voice output device 57.
Is composed of a voice control CPU 52 for controlling voice information, a voice synthesizing IC 53, various ROMs 54 for voice and control, a power amplifier 56 for amplifying a sound signal, and many other various electronic components. That is, a sound signal corresponding to a required game state is generated by the voice synthesis IC 53 or the like, and the generated sound signal is amplified by the power amplifier 56 to a level that can be output by the voice output device 57. The output device 57 is configured to output various sound effects, sounds, and the like.

[0005]

However, if a game machine configured to output various sound effects, sounds, etc. is played for a long time, a power amplifier provided in the sound control means 51 is provided. The temperature of 56 gradually rises due to heat generation. Therefore, as shown in FIG. 12, normally, the power amplifier 56 is provided with a heat removal means 56a such as a heat dissipation plate for heat dissipation so as to perform heat dissipation cooling. Here, in order to improve the heat dissipation efficiency of the power amplifier 56, a large heat removing means 56a is required. In this way, the heat removal means 56
The power amplifier 56, which needs to include a, takes up space in the voice control means 51, and
This causes a problem of increasing the size of the voice control unit 51 itself.

However, as described above, the mechanism set plate G of the pachinko machine P has the main control means Q and the symbol display control means R,
Since it is composed of a large number of other control means and the like and has a limited space, the large-sized voice control means 51 is assembled in a state of being overlapped with other control means and the like. The assembly position will be restricted.
Therefore, the wiring between the respective control means becomes complicated, and there is a problem that workability at the time of assembling and maintaining the gaming machine is deteriorated. Further, when the power amplifier 56 is provided in the voice control means 51, there is no space in the voice control means 51 and sufficient air circulation cannot be performed, so that the heat removal efficiency by the heat removal means 56a is high. There is a fear of decreasing. Further, it is pointed out that by disposing the power amplifier 56, which has a fear of generating noise, in the voice control means 51, the precision electronic parts such as the voice control CPU 52 are adversely affected by noise. Further, the high-performance power amplifier 56 may be large, and when a high-performance power amplifier is used, it may become a larger problem in terms of assembling, maintenance, etc. of the gaming machine. There is.

Further, when the pachinko machine P is set so that the sound output device 57 outputs a sound effect or a sound at a low volume, depending on the environment in which the game machine is installed,
It is also pointed out that it is difficult to identify the low sound range such as the sound effect and the sound output from the sound output device 57. It should be noted that a bass amplification section (not shown) is provided in the voice control means 51 so that the bass range can be clearly identified even when the sound effect or voice output from the voice output device 57 is set to a low volume. A gaming machine that is arranged to amplify the low frequency range has also been proposed. However, since the bass amplification section is composed of a plurality of parts and is likely to be a relatively large part, the sound control means 51 is further increased in size, and the wiring between the various control means is complicated as in the above. There is a fear that workability during assembly and maintenance will deteriorate.

Further, in many conventional pachinko machines P, one audio output device 57 is arranged at a required position,
Corresponding to the sound signal transmitted from the sound control means 51, the single sound output device 57 outputs the entire sound range of various sound effects and sounds. However, if the single sound output device 57 is used to output the entire range, the range in which the low range and the high range can be output is narrowed, and it is pointed out that a monotonous sound is output and lacks power and presence. It Further, when a plurality of audio output devices 57 are provided in the pachinko machine P, the space between the game machines is limited as described above, and therefore the wiring between the audio output device 57 and various control means is provided. Is complicated, and there is a fear that workability at the time of assembly or maintenance is deteriorated.

[0030]

[Operation of Second Embodiment] Next, the operation of the pachinko machine P according to the second embodiment configured as described above will be described.
When the pachinko ball hit by the hitting ball launching device F on the game board J wins various prize holes 11, 17 and 19 and a required gaming state occurs, the voice control means 21 responds to various gaming states. A sound signal that causes the sound output device 27 to output a sound effect or a sound is generated. Then, the generated sound signal is transmitted to each of the high-pass filter 43 and the low-pass filter 44 arranged in the hollow portion 30a of the upper bowl plate 30 via the volume controller 25. Then, when the signal is transmitted to the high-pass filter 43, the low-pitched sound signal in this signal is cut or reduced, so that only the middle-high-pitched sound signal is amplified by the first power amplifier 40 and is output to the middle-high-pitched sound output device 28. It is transmitted and the mid-high range such as various sound effects and voice is output. Further, when the signal is transmitted to the low-pass filter 44, the mid-high range signal of this signal is cut or reduced. Therefore, only the low frequency signal is transmitted to the low frequency amplification unit 38 and amplified, and then the second high frequency signal is further amplified. Power amplifier 41

Further, the sound signal transmitted from the voice control means 21 is divided into a mid-high sound signal and a low sound signal by using the high-pass filter 43 and the low-pass filter 44, and then independently divided into the first and second power amplifiers. Amplification processing is performed at 40, 41, etc., and output is made at the mid-high range output device 28 for mid-high range or the low-range output device 29 for low range, respectively, so that the bass range and mid-treble range are output clearly and with high quality. Therefore, it is possible to output complex sound effects and the like that are powerful and realistic. Furthermore, if a predetermined range is removed by the high-pass filter 43 that removes frequencies lower than the reference frequency and the low-pass filter 44 that removes frequencies higher than the reference frequency, the output sound can be freely set. The sound output device 27 can be changed, and the sound effects and the like output from the sound output device 27 can be easily diversified. By disposing each of the high-pass filter 43 and the low-pass filter 44 in the hollow portion 30a in the upper dish 30, the space on the back side of the gaming machine is compressed, and the assembling property and the maintainability of the gaming machine are impaired. There is no fear.

Further, each of the precision electronic components provided in the voice control means is not affected by noise generated from the power amplifier, and is provided in a hollow portion having a space, so that the precision electronic components are large in size. It becomes possible to use a high-performance power amplifier, and since sufficient air circulation can be performed, effective heat dissipation cooling of the power amplifier can be performed. In addition, since it has a bass amplification unit that amplifies the bass range of the sound signal and sends it to the power amplifier, even when the gaming machine is set to a low volume with the volume controller, the bass range is emphasized and powerful. Sound effects, voices, etc. can be output. Furthermore, by disposing each of the mid-high range output device capable of outputting the mid-high range and the low-range output device capable of outputting the low range, it becomes possible to output the low range and the high range in a wide range and with high quality, It is possible to output complex sound effects that are powerful and realistic.

Further, a bass amplifier is connected to the volume controller, a power amplifier is connected to the bass amplifier, and the mid-high range output device and the bass output device are connected to the power amplifier. Therefore, since it is possible to unify the paths leading to the mid-high range output device and the low-pitched sound output device, even when the mid-high range output device and the low-pitched sound output device are used, it is possible to obtain a complicated effect with excellent power and presence with a few parts Since sound or the like can be output, cost reduction can be achieved. Further, since it is composed of a small number of parts, it is possible to save space and improve the assembling property to the gaming machine.

Further, the sound signal transmitted from the voice control means is divided into a middle-high-pitched sound signal and a low-pitched sound signal by using a high-pass filter and a low-pass filter, and then independently amplified by a power amplifier and a bass amplifier. However, since it is configured to output by the high-pitched sound output device for mid-high range or the low-pitched sound output device for low-pitched sound respectively, it becomes possible to output the bass range and the mid-high range more clearly and with high quality. It is possible to output complex sound effects with excellent feeling. Furthermore, if a predetermined range is removed by a high-pass filter that removes frequencies lower than the reference frequency and a low-pass filter that removes frequencies higher than the reference frequency, the output sound can be freely changed.
