The signal mixed by the mixer 53b is converted into an analog audio signal by the DA converter 54b, amplified by the amplifier 55b, and the volume is manually set by the volume changeover switch 56b to drive the right speaker 30.

With such a structure, any kind of sound is reproduced according to the state of the game, and particularly the sound of 3CH is changed (panned) by changing the strength of the signal output to the right speaker and the left speaker. , The sound image position can be arbitrarily changed to the left or right or the center.

Next, with reference to FIG. 5 to FIG. 7, a description will be given of a sound reproduction state for each game state. In FIG. 5A, the types of sounds and the panning patterns used when the special symbol display unit 11 fluctuates and when the fluctuations stop are indicated by symbols. Channel 1 (CH1) and channel 2 (CH2) symbol rotation sound AL, which is used when the special symbol display unit 11 changes,
AR and the pattern rotating sounds BL and BR are recorded in the memory as stereo sounds respectively. On channel 3 (CH3), the types of sounds D, E, when the left, right, and center symbols stop
F is recorded. When the sound D is reproduced, the sound image is moved from the center (C) to the left (L). When the E sound is reproduced, the position of the sound image is localized at the center (C). F
When the sound is reproduced, the sound image is moved from the center (C) to the right (R).

Next, with reference to FIG. 5 (b) and FIG. 6, the reproduced sound when the special symbol display portion 11 changes and when the change stops is explained. Special symbol display section 1 as shown in FIG. 5 (b)
At the time of change of 1, the symbol rotation sounds AL and AR are reproduced, A
In addition to the sounds of L and AR, D when the left design is stopped
Sound is reproduced, and when the right pattern is stopped, sound F is reproduced.

FIG. 6 shows the reproduced sound until the middle symbol stops after the left and right symbols stop. In the case of deviation (the left and right symbols do not match), in addition to the sounds of AL and AR, the sound of E is played when the middle symbol is stopped. At the time of reach when the left and right symbols are the same, three types of modes for stopping the middle symbols are prepared, and in reach 1, B after the sounds of AL and AR.
The sounds of L and BR are played back, and when the middle pattern stops, B
The sound of E is reproduced in addition to the sounds of L and BR.

In Reach 2, after the sounds of AL and AR, BL,
The BR sound is played. There is a low-speed rotation on the way, and the sounds D and F are reproduced at that time. When the middle pattern is stopped, the E sound is reproduced in addition to the BL and BR sounds. In the reach 3, the sounds of BL and BR are reproduced after the sounds of AL and AR. After that, frame feeding is performed, and when the images are fed frame by frame, the sounds D, F, D, F, E are sequentially reproduced.

In this way, when all the symbols are stopped, a big hit may occur, but FIG. 7 (a) shows the types of sounds used in the big hit and the panning pattern.
Is indicated by a symbol. The jackpot sounds GL and GR and the jackpot sounds HL and HR are recorded in the memory as stereo sounds in the channels 1 (CH1) and 2 (CH2), respectively. Channel 3 (CH3) records I (V winning sound), J (voice 1), K (voice 2) M (sound effect 1), N (sound effect 2), and O (sound effect 3). ing. The panning state at the time of reproducing each of these sounds is indicated by the same reference numerals as those in FIG.

Next, with reference to FIG. 7B, an example of a reproduced sound at the time of a big hit will be described. First of all, when it comes to the jackpot, with the release of the first special variable winning ball device, jackpot sound GL,
GR is played. If there is a specific ball detector output (V winning) in the meantime, in addition to the sounds of GL and GR, I,
The sound of J is played continuously. When the open / close plate is closed, the big hit sounds GL and GR stop, but immediately before that, N and K sounds are continuously reproduced in addition to the sounds of GL and GR. After the jackpot sounds GL and GR are stopped, only N sounds are reproduced twice in succession.

When the special variable winning ball device is released for the second time due to the V winning, the big hit sounds HL and HR different from the first big hit sounds GL and GR are reproduced. Since the second big hit sound is made different from the first big hit sound in this way, it is possible to let the player recognize that the V prize has been released. At the start of the reproduction of the jackpot sounds HL and HR, the sound of J is reproduced in addition to the sounds of HL and HR. In the meantime, if there is an output (V winning) of the specific ball detector,
In addition to the sounds of HL and HR, the sounds of I and J are continuously reproduced. When the big hit sounds HL and HR are stopped, H
In addition to the sounds of L and HR, the sounds of M and O are continuously reproduced. After the jackpots HL and HR are stopped, the N sound is reproduced twice. In this way, a variety of sounds and sound images can be realized in accordance with the game state by using a small amount of sound data.

FIG. 8 shows a modification of the sound circuit of the above embodiment. In this example, the sound circuit 46A is provided with two-channel memories 50a and 50b, and these memories form a pair to record various compressed stereo sounds as in the previous example. The PCM decoders 51a and 51b read out sound data from the memories 50a and 50b of the respective channels and demodulate into PCM sound data. That is, data of various sounds addressed by the basic circuit 38 is demodulated.

The P of each channel generated in this way
The sound intensity of the CM audio signal is adjusted by the electronic volumes 52a and 52b which receive the command from the basic circuit 38, respectively. The output signals from the electronic volume controls 52a and 52b are converted into analog audio signals by the DA converters 54a and 54b, amplified by the amplifiers 55a and 55b, and the volume is manually set by the volume changeover switches 56a and 56b. The left speaker 31 is driven.

In this example, the electronic volumes 52a, 52
In b, the level of the whole sound can be adjusted, and the sound image can be moved by changing the strength of left and right sounds. Although the types of sounds are smaller than in the previous example, a variety of sound image movements are possible, and a variety of sound effects can be reproduced according to the game state.
