  Hereinafter, the gaming machine of the present invention will be described in more detail based on examples. FIG. 16 is a block diagram illustrating the overall configuration of the pachinko machine according to the embodiment. The illustrated pachinko machine has a main control board 1 for centrally controlling gaming operations, a symbol control board 2 for changing the characters and symbols displayed on the liquid crystal display 8, and speakers R and L on the left and right of the gaming machine. A sound control board 3 that realizes a novel sound effect by driving the lamp, a lamp control board 4 that realizes a lamp effect by blinking lamps, a payout control board 5 that pays out game balls, and a payout control board 5 And the power supply board 6 that receives AC24V and supplies a DC voltage to each part of the apparatus.

  The main control board 1, the design control board 2, the voice control board 3, the lamp control board 4, and the payout control board 5 are each composed of a computer circuit having a one-chip microcomputer. Based on the control command from the main control board 1, the individual control operations described above are realized. In this embodiment, the control command has a length of 2 bytes and is transmitted by a one-way parallel communication method, but is not particularly limited to this configuration.

  FIG. 17 is a block diagram showing a circuit configuration of the audio control board 3. As shown in the figure, the sound control board 3 is mainly composed of a one-chip microcomputer 10 and amplifiers 11R and 11L that amplify two sound analog signals (effect sound SE and background sound BGM) output from the one-chip microcomputer 10. In preparation. The one-chip microcomputer 10 includes an input port 12 that receives a control command from the main control board 1, a CPU core 13 that controls the operation of the voice control board 3, and a TPU (Timer Pulse) that outputs various signals based on a system clock. Unit) 16, an interrupt controller 14 that receives internal interrupt signals CH0 and CH1 from TPU 16 and a strobe signal STB from main control board 1, and D that outputs PCM audio data restored in software and outputs an audio analog signal / A converter 15, ROM (Read Only Memory) 17 that stores the control program and ADPCM data (adaptive differential pulse code modulation) in a fixed manner, and RAM (Random Access) used as a work area for the control program Memory) 18.

  As shown in FIG. 17, the interrupt controller 14 is supplied with internal interrupt signals CH0 and CH1 from the TPU 16 and a strobe signal STB from the main control board 1, both of which can be prohibited (masked). It is a signal. The strobe signal STB is a signal output from the main control board 1 together with the control command. The strobe signal STB is supplied to the interrupt controller 14 as an IRQ (Interrupt Request) signal, and the interrupt controller 14 that has received this signal sends an interrupt signal to the CPU core 13. In addition to supplying INT, an interrupt vector specifying an interrupt processing routine is output.

  The TPU 16 channel 0 and channel 1 are set to output an internal interrupt signal, respectively, but the interrupt signal CH1 from the channel 1 is set to be emitted every 4 mS, and the interrupt signal CH0 from the channel 0 is Are set to be emitted at each sampling period (τ) individually set by the control program. Here, the sampling period means the output interval (τ) of the audio analog signal output from the D / A converter 15.

  The sampling period (τ) is individually set by the control program so that the sampling period can be appropriately changed according to each voice message output from the D / A converter 15. For example, when reproducing audio data (ADPCM data) acquired at sampling frequencies of 8 KHz, 16 KHz, and 32 KHz and stored in the ROM 17, the time intervals (τ) of 125 μS, 62.5 μS, and 31.25 μS, respectively. When the interrupt signal CH0 is issued, the ADPCM data is converted into PCM data and output from the D / A converter 15 at a timing corresponding to the sampling frequency.

  The D / A converter 15 has a built-in 2-channel D / A conversion circuit that can operate independently. When digital data is written into the 8-bit data registers DADR0 and DADR1, D / A conversion is performed. Analog outputs DA0 and DA1 are output. As shown in the figure, in this embodiment, the analog output DA0 is supplied to the right channel amplifier 11R, and the analog output DA1 is supplied to the left channel amplifier 11L to output the corresponding speakers SP (R) and SP (L). Driving.

  1 to 5 exemplify a reference table for explaining the relationship between the control command received from the main control board 1 and the voice information issued from the voice control board 3. In this embodiment, sound effects (SE) and background sounds (BGM) are output from the left and right speakers SP in response to a 2-byte length control command transmitted from the main control board 1. Next, this series of processes will be schematically described.

  As shown in FIG. 1A, a 1-byte Fi command (complete information Full Intelligence Command) is specified corresponding to the received 2-byte control command. Here, the Fi command is to completely specify a series of audio information. For example, when the symbol change operation is started in the liquid crystal display 8 in accordance with a winning at the symbol start opening, the symbol change is performed. (1) “I can expect this time!” → (2) ... (silence) → (3) "Hore reach!" → (4) ... ( Silence state) → (5) A series of sound effects SE such as “Yeah! Big hit !!!!” are specified together with the background sound BGM (usually music).

  The Fi command is configured by combining the classification information (1) to (5) as described above, and the classification information is specified by the Si command (Semi Intelligence Command). That is, the Fi command is composed of a combination of Si commands. For example, the sound effect SE output from the left channel speaker SP (L) is expressed by the combination of a plurality of Si commands (1) “This time (2) ... (silenced state), (3) "Hore reach!", (4) ... (silent state), (5) "Yeah! A series of voice information “big hit!” Is specified.

  FIG. 2 schematically shows the relationship between the Fi command, the Si command, and the sound NO. As shown in FIGS. 2A and 2B, for one Fi command, an Si command for the right channel background sound (BGM) and an Si command for the left channel sound effect (SE) are provided. Identified. For example, in the case of the Fi command with the command number 01H, a combination of a series of 10 Si command numbers (50H, 23H, 50H, 24H, 41H, 50H, 4BH, 4CH, 5CH, 50H) is specified as the sound effect. As a background sound, a combination of a series of seven Si command numbers (01H, 51H, 02H, 51H, 10H, 0FH, 51H) is specified. H means a hexadecimal number.

Each Si command is defined along with its playback time. In the case of the sound effect (SE) illustrated in FIG.
(1) Si command 50H (silence) that requires 9.4 seconds of playback time
(2) Si command 23H, which requires a playback time of 0.7 seconds
(3) Si command 50H (silence) that requires a playback time of 12.7 seconds
(4) Si command 24H requiring a playback time of 1.0 seconds
(5) Si command 41H requiring a playback time of 0.8 seconds
(6) Si command 50H (silence) that requires 3.6 seconds of playback time
(7) Si command 4BH requiring a playback time of 2.0 seconds
(8) Si command 4CH that requires a playback time of 0.8 seconds
(9) Si command 5CH requiring 11.27 seconds of playback time
(10) Si command 50H (silence) that requires a playback time of 0.004 seconds
Means that the Fi command 1 is activated. Then, which Si command is to be executed among the series of Si commands is instructed by the SE progress counter CNTSE.

These points are the same for the background sound. In the case of the background sound (BGM) illustrated in FIG.
(1) Si command 01H that requires 9.4 seconds of playback time
(2) Si command 51H (silence) requiring a playback time of 0.7 seconds
(3) Si command 02H requiring a playback time of 12.7 seconds
(4) Si command 51H (silence) requiring a playback time of 3.6 seconds
(5) Si command 10H which requires a playback time of 4.8 seconds
(6) Si command 0FH which requires 9.1 second playback time
(7) Si command 51H (silence) requiring a playback time of 0.004 seconds
Means that the Fi command 01H is activated. The BGM progress counter CNTBG indicates which Si command is currently to be executed in the series of Si commands.

  Each Si command is further configured to specify a combination of a sound NO that is an audio part and its playback time. For example, in the example of FIG. 2A, the Si command 5CH is a sound NO47H requiring a reproduction time of 0.6 seconds → a sound NO47H requiring a reproduction time of 0.6 seconds → ... → reproduction of 1.1 seconds. Sound NO47H requiring time →... → Equipped with sound NO56H requiring reproduction time of 2 seconds. As described above, the sound NO and the reproduction time thereof are not necessarily fixed, and the reproduction time is appropriately changed. Then, the progress counter PTCNT indicates which sound NO should be executed among the series of sound NOs. In FIG. 2, ENDCD is a code indicating the end of data, and the playback time is in units of mS (milliseconds) and is specified in the format ** / 4. This is because interrupt processing occurs every 4 ms.

  As described above, in this embodiment, the Fi command is specified from the control command, the Si command combination is specified by the Fi command, and each Si command is configured to specify the sound NO combination. 3 to 5 illustrate in more detail the relationship from the identification of the Fi command number to the reproduction of the audio signal, and FIG. 3 illustrates the relationship between the Fi command number and a series of Si commands for realizing this. Is shown. FIG. 4 shows the relationship between the Si command and a series of sound NOs for effecting this, and FIG. 5 shows the relationship between the sound NO and the storage location of the corresponding audio data (ADPCM data). Is shown.

  Hereinafter, the control program of the voice control board 3 will be described based on these points. In the present embodiment, the control program for the voice control board 3 includes a main routine (FIG. 6) that starts executing after power-on, a timer interrupt processing routine (FIG. 7) that is started every predetermined time (4 mS), A sound output interrupt routine (FIG. 14) for supplying PCM data to the D / A converter at each sampling period (τ), a reception interrupt routine (FIG. 15) started upon receiving a strobe signal STB from the main control board 1, It is composed of an abnormal interrupt routine (not shown) that is started due to a program runaway or the like.

  When a timer interrupt (FIG. 7), a sound output interrupt (FIG. 14), and a reception interrupt (FIG. 15) are started, the CPU is disabled. In this embodiment, the CPU is interrupted in the interrupt processing routine. Since the state is not returned to the permitted state, if any interrupt processing is started during the execution of the main routine, the other interrupt signals will be held thereafter unless the EI instruction is executed in the main routine.

  First, the main routine will be described with reference to FIG. 6. When the gaming machine is powered on, the RAM 18 of the one-chip microcomputer 10 constituting the voice control board 3 is cleared to zero (ST1) and other initial processing is performed. Perform (ST2). Next, after a voice activation process is performed to issue a unique guidance voice message when the power is turned on (ST3), the CPU is set to an interrupt enabled state (EI: enable interrupt) and the built-in module of the one-chip microcomputer 10 is installed. It is reset to the initial state (ST4). Note that a maskable interrupt signal is accepted only after the CPU executes the EI instruction.

  Subsequently, a process related to the sound control work table (see FIG. 13) that manages the activation of the sound NO is performed (ST5). Specifically, as shown in FIG. 12, the processes of steps ST92 to ST97 are performed on the control work tables SNDCTBL (for BGM) and SNDCTBL (for SE) shown in FIG. First, the data of the SNDNO address storing the sound NO in the work table SNDCTBL and the inverted data of the data of the SNDNOCS address are compared, and if they match, the data of the SNDNO address is used as the sound NO in the subsequent processing (ST92). ).

  On the other hand, if the two do not match, the data in the backup area SNOBUP is used as the sound NO on condition that the data in the SNOBUP address and the inverted data of the data in the SNOBUPC address match (ST92). If neither data can be used, silence processing is performed so that no sound is produced from the speaker.

  As described above, the validity of the data (sound NO) is strictly checked in the case of the present embodiment, in addition to the occurrence of the data reception interrupt (ST15) during the execution of the main routine, the timer interrupt every 4 ms. (FIG. 7) and the audio output interrupt (FIG. 14) are executed in parallel, and the control process for the sound NO is performed at a complicated timing in each case. Because.

  Subsequently, the sound NO and its inverted data are stored in the SNOBUP address, SNDNOCS address, and SNOBUPC address of the work table SNDCTBL (ST93). Further, the data of the ADFLG address, SNDADR address, SNDFLG address, SNDNO address, DELTA address, XN address, ADFLG address, and SNDADR address of the work table SNDCTBL are acquired in this order (ST94). Here, the reason why the data at the ADFLG address and the SNDADR address is acquired twice is that the stored data may change due to a timer interrupt (FIG. 7) or an audio output interrupt (FIG. 14) during the process of step ST94. Because there is. Therefore, as long as the first and last data do not match, all the data is acquired again.

Next, (SNDFLG + SNDNO + DELTA + ADFLG + XN + SNDADRH + SNDADR L), the checksum is calculated by the 16-bit addition operation, and the inverted data is converted to B Store in the CS address (ST95). Note that SNDADRH is the upper 2 bytes of the 4-byte length address value (4 bytes from SNDADR address). L means the lower 2 bytes. In addition, BDELTA address of work table SNDCTBL, B Address XN, B ADFLG address, B SNDADR address, B Backup data is stored in the addresses SNDNO and BSNDFLG. This also takes into consideration that the stored data may change due to the occurrence of a timer interrupt (FIG. 7) or an audio output interrupt (FIG. 14) during the processing of step ST94.

  Subsequently, the address information and other information corresponding to the sound NO are acquired based on the reference table SNDBL of FIG. 5A, and stored in the SNDSTR address, SNDEND address, SNDLOOP address, and SMPFRQ address of the work table SNDCTBL (ST96). ).

  The processes in steps ST92 to ST96 are performed for the control work tables SNDCTBL (for BGM) and SNDCTBL (for SE). The contents of the control work table SNDCTBL are updated during the execution of the main routine (mainly ST4). This is because the audio information output process (FIG. 14) is also progressing every sampling period (τ).

When the processing of step ST5 is completed as described above, command conversion processing and random number distribution processing are performed (ST6). If a new control command has been received, 5AH is stored in the COMWRT address (ST6). Here, the command conversion process is a RING that cyclically stores control commands from the main control board 1. The BUFFER area (see the reception buffer in FIG. 15B) is checked, and if a new control command is detected, the control command is referred to the Fi command by referring to the conversion table as shown in FIG. It is processing to convert to. The random number distribution process is a process for changing the Fi command with reference to a lottery table as shown in FIG.

In the random number distribution process, specifically, the Fi command is changed by the Fi command determined by the command conversion process and the random value RND. Here, the random value RND is, for example, 0 to 255 (= RND MAX). Therefore, in the example of FIG. 1B, when the Fi command determined by the command conversion process is 11H, if 0 ≦ random number value RND ≦ 68 or 79 ≦ random number value RND ≦ 255, Fi command = 11H. However, if 69 ≦ random number value RND ≦ 78, the Fi command is changed to 83H.

Next, the random value RND is updated (ST7). In this embodiment, the random value RND is 0 to 255 (= RND). MAX), it is updated by incrementing (+1) the random number value RND within the numerical range. Subsequently, the value of the sound NO write completion flag RCMDFLG is checked. If the flag RCMDFLG is not set, it is determined that there is no audio information to be newly output, and the process returns to step ST4 (ST8). The sound NO write completion flag RCMDFLG is set when the sound NO corresponding to the new control command is determined in the timer interrupt process (FIG. 7) (see ST58 in FIG. 9 (a)).

  Therefore, if it is confirmed in step ST8 that the sound NO write completion flag RCMDFLG is set, sound NO analysis processing is executed (ST9). Specifically, in the timer interrupt process (FIG. 7), the written sound NO is copied to the work area RCMD, and various information corresponding to the sound NO is stored in the corresponding column of the sound control work table SNDCTRL. (ST9).

  In the sound NO analysis process (ST9), the validity of the sound NO is also determined. Therefore, if it is determined that the sound is not valid, the process returns to step ST4. The process proceeds to output start processing (ST11). Sound NO is not valid because it is considered that a plurality of interrupt processes may be executed in multiple layers. In such a case, the audio output activation process is skipped. Is prevented from being output.

  On the other hand, if it is determined in step ST10 that the sound NO is valid, a series of sound data sampling periods (τ) corresponding to the extracted sound NO are specified as the sound output activation process. Thus, the internal interrupt signal CH0 is set to be output from the TPU 16 at every sampling period (τ) (ST11). Then, the process returns to step 4. However, since the internal interrupt signal CH0 is set to be output from the TPU 16, thereafter, an internal interrupt occurs every sampling period (τ) and corresponds to the specified sound NO. Audio data is output every sampling period (τ) (see FIG. 15).

As described above, after the power is turned on, the processing from steps ST4 to ST11 is repeated in an infinite loop. In parallel with such main routine processing, timer interrupt processing shown in FIG. 7 is performed. In the timer interrupt process, the BGM variable TIMEBG and the SE variable TIME are used to manage the playback time of the Si command. It is decremented (-1) until SE becomes zero. Further, the BGM variable PT1 and SE variable PT2 that manage the reproduction time of the sound NO are decremented to zero. As described above with reference to FIG. 2, the playback time of the Si command and the sound NO is specified and extracted. However, in order to realize the specified playback time, each variable TIMEBG, TIME SE, PT1, and PT2 are decremented. Since the interrupt period of the timer interrupt is 4 mS, for example, 9400/4 = 2350 interrupt processes are required to realize a reproduction time of 9.4 seconds.

Subsequently, it is determined whether or not the value of the work area COMWRT is 05H (ST21). As described in step ST6 of FIG. 6, when a new control command is acquired, 05H is written in the work area COMWRT. So work area COM When WRT = 05H, the Fi command work area and the Si command work area are initialized (ST22), and then the Fi command stored in the command buffer area COMSD (not shown) is COM which is Fi command storage area Store in NUM (ST23).

The work areas for the Fi command and the Si command have the data structures shown in FIGS. 7B and 7C, and the storage area COMNUM is provided in the work area for the Fi command. In addition, the time variable TIME for the Si command which becomes a problem in step ST20. BG, TIME SE is provided in the work area for Fi command, and time variables PT1 and PT2 for sound NO are provided in the work area for Si command.

When the processing in step ST23 is completed, the bit stored in the Fi command storage area COMNUM is inverted, and the buffer area BUP In addition to storing in NUM, zero is stored in the COMWRT address to indicate that the initial process for the new control command is completed (ST24). COM WRT address = 0 (COM If WRT ≠ 05H), the processing of steps ST22 to ST24 is skipped.

Subsequently, Fi command expansion processing is performed (ST25). The details of the Fi command expansion process are as shown in FIG. 8, but in a simplified manner, based on the Fi command stored in COMNUM and the Si progress counter, the Si command to be executed from now is specified. . The Si progress counter means CNTBG and CNT in the Fi command work area. This is the value of SE, and for one Fi command, a BGM (background sound) Si command and an SE (notification sound) Si command are specified. The specified BGM (background sound) Si command and SE (notification sound) Si command are respectively stored in the BGM area 1 and the PTNUM of the SE area 2 in FIG.

As a result of the above processing, the Si command to be executed is specified, and then data expansion processing is performed for the Si command (ST26). The details of the Si command data development process are as shown in FIG. 9, but in a simplified manner, the sound NO to be activated is identified based on the Si command and the sound NO progress counter PTCNT. Here, the progress counter is the PT of the BGM area 1 CNT and the value of PTCNT in SE area 2, and sound NO for BGM and SE are specified for one Fi command. Then, the specified two types of sound NOs are stored in RCMDBF1 and RCMDBF2 shown in FIG. 7 (d), respectively.

FIG. 8 is a flowchart showing specific contents of the Fi command expansion process (ST25 in FIG. 7). First, an error confirmation process (ST30) for the Fi command work area (see FIG. 7B) is executed. Specifically, (a) COM NUM value and BUP Comparison with the inverted value of NUM, (b) COM Validity check of whether Fi command stored in NUM is within predetermined numerical range, (c) CNTBG value and BUP Comparison with BG inversion value, (d) CNT SE value and BUP Comparison with the inverted value of SE is performed, and if any abnormality is detected, the work area for Fi command (FIG. 7B) is initialized and the process is terminated. As described above, in this embodiment, since abnormality determination is performed prior to the expansion process of the Fi command, abnormal voice information is not output.

Next, it is determined whether or not the value of the variable TIMEBG has become zero (ST31). Variable TIME BG manages the playback time of the BGM Si command, and is a variable that is decremented every 4 mS in step ST20 of FIG. Therefore, if TIMEBG = 0, the process proceeds to step ST32 in order to give the next Si command to be executed. Specifically, COM Data Dx (Si command) corresponding to the BGM progress counter CNTBG is acquired from the group of Si commands corresponding to the storage data (Fi command) at the NUM address (ST32).

Then, it is determined whether or not the Si command is the end code ENDCD (see FIG. 3) (ST33). If it is not the end code ENDCD, the reproduction time of the Si command is set as the initial value of the time variable TIMEBG. . Next, it is determined whether or not the data Dx acquired in step ST32 is a continuation code (ST35). If it is not a continuation code, the BGM work in the Si command work area (FIG. 7C) is determined. Area 1 is initialized (ST36). Specifically, the 4th address (PTTIME, PT) from the SEMIDT address shown in FIG. NUM, PT CTH is stored with 00H and the next 2 addresses (PT NUM BP, PTCNT BP) stores 0FH.

Thereafter, the Si command (Dx) acquired in the process of step ST32 is stored in the PTNUM address of the work area 1 for BGM, and the inverted data of the Si command (Dx) is stored in the PT of the BGM work area 1. NUM Store in the BP (ST37). The BGM progress counter CNTBG is incremented (+1) and the BGM progress counter CNT BUP the inverted data of BG Store in the BG address (ST38). The inversion data is stored so that the validity of the Si command to be executed from now on and the validity of the value of the BGM progress counter for specifying the sound NO can be checked when necessary.

  With the above processing, the processing for the BGM area 1 in the work area for the Si command (FIG. 7C) is completed, and then the processing shifts to the processing for the SE area 2. The specific processing contents of steps ST39 to ST46 are substantially the same as the processing contents of steps ST31 to ST38 described above, and necessary data is stored in SE area 2 (6 addresses starting from SEMIDT + 6). . The value of the SE progress counter CNTSE is also incremented (+1) (ST46).

Next, the Si command data expansion process (ST26) of FIG. 7 will be described based on the flowchart shown in FIG. First, Si command error check processing is performed (ST50). Specifically, (a) PT in the BGM area 1 shown in FIG. NUM address data and PT NUM Contrast with inverted data at address BP, (b) PT CNT address data and PTCNT Contrast with inverted data at address BP, and (c) PT in SE area 2 NUM address data and PT Contrast with inverted data at address NUMBP, (d) PT CNT address data and PT CNT Processing such as comparison with the inverted data at the BP address is performed, and when an abnormality is detected, the BGM area 1 and the SE area 2 are initialized and the processing is terminated.

  Next, the register R3 is cleared to zero and initial processing is performed for the BGM area 1 in the Si command work area (FIG. 7B) (ST51). As a result, work for the BGM area 1 is initially performed, and it is first determined whether or not the value of the time variable PT1 for managing the playback time of the BGM sound NO is zero (ST52). The time variable PT1 is set to an initial value in the process of step ST56 of FIG. 9A, and is decremented (−1) by the process of step ST20 of FIG. The case where PT1 = 0 is when it is time to finish executing the current sound NO and shift to the execution of the next sound NO.

First, from the address list of the instruction table PARTSCOM as shown in FIG. 4A, the PT of the BGM area 1 (FIG. 7C) is obtained. PARTS corresponding to Si command stored at NUM address COMi address information is extracted (ST53). Next, from the group of sound NO data stored in the extracted PARTSCOMi area (see FIG. 4B), the sound NO progress counter PT in FIG. Sound NO data Dz corresponding to CNT is extracted (ST54).

  If the extracted data Dz is not the end code ENDCD, the playback time of the sound NO specified by the processing in step 54 is initialized to the PTTIME address of the BGM area 1 in FIG. 7C (ST56). ). If the data Dz is not a continuation code, the extracted sound NO (Dz) is stored in the work area RCMDBF1 shown in FIG. 7D, and the corresponding bit of the write completion flag RCMDFLG is set to 1. (ST58).

In addition, the value of the sound NO progress counter PTCNT in the BGM area 1 in FIG. CNT Store in the BP address (ST59). With the above processing, the processing for the BGM area 1 in FIG. 7C is completed. Next, the value of the register R3 that has been reset to zero in the processing of step ST51 is checked (ST70), and the register R3 is set to 05H. After writing, initial processing is performed for the SE area 2 (ST71), and the process returns to step ST52.

As a result, the same work as the work for the BGM area 1 described above is subsequently performed on the SR area 2. That is, if PT2 = 0, from the group of sound NO data stored in the PARTSCOMi area (see FIG. 4B), the sound NO progress counter PT in the SE area 1 in FIG. Sound NO data Dz corresponding to CNT is extracted (ST54). Then, the playback time of the sound NO specified by the processing in step 54 is initialized to the PTTIME address of the SE area 2 in FIG. 7C (ST56), and the sound NO (Dz) is set in FIG. And the corresponding bit of the write completion flag RCMDFLG is set to 1 (ST58). The process of step ST58 is as shown in detail in FIG. 9B, and FIG. 9C is a transcription of FIG. 7D.

  Next, the flowchart of FIG. 10 will be described. FIG. 10 shows the details of the sound NO analysis process (ST9) of FIG. In the sound NO analysis process, first, the corresponding bit of the sound NO write completion flag RCMDFLG shown in FIG. 9C is checked, and the sound NO is stored in the sound NO first buffer RCMDBF1 (see FIG. 9C). It is determined whether or not (ST70). If the determination result is Yes, the data of RCMDBF1, which is the reception buffer 1, is copied to the work area RCMD address, and the corresponding bit of the sound NO write completion flag RCMDFLG is reset to indicate the work end (ST71).

  On the other hand, if the reception buffer 1 is determined to be empty by checking the sound NO write completion flag RCMDFLG, the corresponding bit of the sound NO write completion flag RCMDFLG is checked and the sound NO is stored in the sound NO second buffer RCMDBF2. It is determined whether it has been performed (ST72). If the determination result is Yes, the data of RCMDBF2, which is the reception buffer 2, is copied to the work area RCMD address, and the corresponding bit of the sound NO write completion flag RCMDFLG is reset to indicate the work end (ST72).

  The reason why the reception buffer 1 and the reception buffer 2 are checked in this way is that only one piece of audio information can be processed at a time. That is, the sound NO stored in the reception buffer 1 is stored in the RCMD address, and after the subsequent sound output activation (ST11), the processing of steps ST4 to ST8 is performed (the internal interrupt processing of CH0 is executed only once during this time). The sound corresponding to the reception buffer 1 may be output), and the sound NO stored in the reception buffer 2 is stored again at the RCMD address. If it is determined in step ST8 in FIG. 6 that “sound NO writing has been completed” but the determinations in steps ST70 and ST72 in FIG. 10 are both NO, the carry flag CY is set to 1. Set and finish the process (ST80).

  However, in a normal case, the sound NO stored in the reception buffer 1 or the reception buffer 2 is copied to the RCMD address (ST71, ST73). Next, the value of the sound NO is within a predetermined numerical range. It is determined whether or not it is (ST74). For example, if the sound NO is assigned to a numerical value range of 0 ≦ sound NO ≦ SNDmax, it is determined that a sound NO greater than SNDmax is an error, and the process proceeds to step ST80. Since such a determination process is provided, it is possible to prevent an abnormal sound from being output or a program from running away.

  If it is determined that the sound NO does not exceed the predetermined numerical range, the value of the sound NO is further checked, and if it is normal, the carry flag CY = 0 is set, and if it is abnormal, the carry flag CY = 1 is set (ST75). ). The sound NO check includes a process of referring to the reference table SNDTBL shown in FIG. 5, and if the content of the corresponding address in the reference table SNDTBL corresponding to the sound NO is zero, there is no ADPCM data. The carry flag CY = 1 is set as an abnormality.

  When the processing of step ST75 is completed, it is next determined whether or not the value of the sound NO is abnormal based on the value of the carry flag CY (ST76). If normal, the sampling frequency for reproducing the sound NO is acquired. (ST77). Specifically, as shown in FIG. 11A, a sound control work table SNDCTBL reserved for the background sound (BGM) and the sound effect (SE) (FIG. 11B, FIG. 13). Of which is used (ST80), and the sound NO is stored in the corresponding column of one of the work tables SNDCTBL (ST81). Of the sound control work tables SNDCTBL for background sound (BGM) and sound effect (SE), which should be used can be specified from the sound NO. That is, as shown in FIGS. 5B and 5C, it is possible to specify from sound NO whether it is related to BGM sound or SE sound (see BGM1 + 2 and SE1 + 2). ) Including the subsequent processing, one of the specified sound control work tables SNDCTBL is used.

  When the processing of step ST81 is completed, the position where the sound data (ADPCM data) corresponding to the sound NO is stored is specified, and information such as the start address and end address of the sound data is used for sound control from the header information. Store in the corresponding column of the work table SNDCTBL (ST82). Further, the sound flag (BGM / SE), the information on the presence / absence of repeated playback LOOP, and the sampling frequency are acquired from the header information of the audio data, and stored in the corresponding column of the sound control work table SNDCTBL (ST83). Finally, a data check process is performed (ST84). The processing content is as described in the flowchart of FIG. 12, and is the same as the process related to step ST5 of FIG.

  FIG. 14 is a flowchart for explaining an interrupt process for voice output (internal interrupt of CH0 of TPU 16) started on condition that the sound output activation process (ST11) of FIG. 6 is executed. For example, when it is instructed to reproduce the audio data with the sampling frequency of 8 KHz by the processing of step 11, this CH0 interruption process is executed every 125 μS, and the audio data with the sampling frequency of 16 KHz is to be reproduced. , The CH0 interrupt process is executed every 62.5 μS. Since this internal interrupt is an interruptable (maskable) interrupt, it is accepted on condition that the CPU executes the EI instruction (see ST4). In short, infinite loop processing (mainly ST4 to ST8). Is a condition for execution.

Based on the above, FIG. 14 will be described. In the audio output interrupt (SNDINT), first, SNDDATA The contents of the R address are output to the data register DADR0 of the D / A converter 15 (STOUT1). In the SNDDATAAR address, the previous interrupt processing (SND Since the PCM data (8-bit length) of the BGM sound for the right channel is stored by the process of step STOUT5 in (INT), the PCM data is output to the D / A converter 15. The D / A converter 15 converts the received PCM data into an analog signal DA0 and outputs it to the right channel amplifier 11R.

Next, the contents of the address SNDDATAL are output to the data register DADR1 of the D / A converter 15 (STOUT2). SNDDATA Since the PCM data of the SE sound for the left channel is stored at the address L by the process of step STOUT8 in the previous interrupt process (SNDINT), the PCM data is output to the D / A converter 15. The D / A converter 15 converts the received PCM data into an analog signal DA1 and outputs it to the left channel amplifier 11L.

  In parallel with the operation of the D / A converter 15, the CPU 13 acquires the address value stored at the address SNDAD of the work table SNDCTBL for sound control (BGM), and uses the compressed audio data (ADPCM data). Obtain (STOUT3). Also, the address value (data address during sound data conversion) stored in the SNDADR address is updated to the next address value (STOUT4).

  Next, the ADPCM data acquired in the process of step STOUT3 is converted into PCM data (background sound BGM) and stored in the address SNDDATAAR (STOUT5). In this embodiment, since 8-bit PCM data is compressed into 4-bit ADPCM data, it is restored.

  Since the background sound (BGM) has been restored by the above process, the restoration process for the sound effect (SE) is performed next. Specifically, the address value stored in SNDADR of the work table SNDCTBL for sound control (SE) is acquired to obtain compressed audio data (ADPCM data) (STOUT6), and the address stored in the SNDADR address. The value (data address during sound data conversion) is updated to the next address value (STOUT 7).

  Then, after ADPCM data acquired in the process of step STOUT6 is converted to PCM data (sound effect SE) (STOUT7), it is stored in the work area SNDDATAAL and the interrupt process is completed (STOUT9). Note that the audio data stored in the processing of steps STOUT5 and STOUT8 is output to the D / A converter at the next audio interruption (STOUT1, STOUT2).

  Next, a reception interrupt for receiving a control command from the main control board 1 will be described with reference to FIG. As described above, the main control board 1 outputs the strobe signal STB together with the output of the control command, and the processing of FIG. 15 is started due to the reception of the strobe signal. Since this interrupt is also an interruptable (maskable) interrupt, it is accepted on the condition of one round of the main routine (mainly ST4 to ST8).

  In the reception interrupt, data is continuously received twice from the command input port 12, and it is first determined whether or not the two data match (identical check). This is because control command data that is garbled due to the influence of noise or the like is not received, and the process proceeds to the next reception process on condition that this identity check is OK for seven consecutive times. (STIN1, STIN2).

  If the determination in step STIN2 is Yes, then the control command received this time is compared with the control command received immediately before, and if they match, the process is terminated as it is (STIN3). This is because the same control command cannot be continuously output from the main control board 1, so that it is determined that there is some malfunction and the received control command is discarded.

On the other hand, if the newly received control command is different from the control command received immediately before, the control command is stored at the address indicated by the write pointer WRPOINT (STIN4). The write pointer WR The value of POINT is updated (STIN5). As shown in FIG. 15B, the reception buffer for storing the control command has a ring buffer structure, and the value of the write pointer WRPOINT is updated cyclically. The control command stored in the reception buffer is read out in the process of step ST6 in FIG. At the time of reading, a read pointer RDPOINT is used, and this read pointer RD POINT is also used by being updated cyclically.

  Although the embodiments of the present invention have been specifically described above, the gist of the present invention is to configure a plurality of speakers so that they can be driven independently, and the others can be appropriately changed. For example, in the above-described embodiment, the background sound BGM is always generated from the right speaker, while the sound effect SE is always generated from the left speaker. However, the generation position of the SE sound and the BGM sound may be changed as appropriate. Is preferred. In the case of such a gaming machine, when a big hit state is reached by the lottery process on the main control board 1, a special symbol variation effect (not necessarily finished in the winning state) is not immediately notified to the liquid crystal display 8. The big hit state is notified after the reach action (which is not necessarily limited) is continued for a certain period of time, but it is preferable to reverse the left and right speaker operations with a predetermined probability in accordance with the reach action.

  In this second embodiment, the speaker reversing operation is executed with a predetermined probability, so that the jackpot state is voiced with a certain degree of reliability, giving the player a new interest to infer the jackpot state. Can do. For example, in this embodiment, various types of reach actions in the liquid crystal display 8 are prepared (normal reach, special reach, etc.), and the reliability as the notice operation of the big hit state differs depending on the type, but the symbol control board In accordance with the start of the reach action with the reliability of N% 2 (the probability of ending in the big hit state is N%), the voice control board 3 has a probability of the reliability of M% (the probability of ending in the big hit state is M%). ) To reverse the use position of the speaker.

  In addition, even when a symbol effect (reach action) that ends in a winning state is executed, the use position of the speaker is reversed with a predetermined reliability, and a symbol effect that finally ends in a lost state is executed. However, it is preferable to reverse the use position of the speaker with a predetermined reliability. That is, even if the reversing operation of the speaker occurs, it may end in a lost state, and conversely, it may end in a big hit state even if the reversing operation of the speaker does not occur.

  Hereinafter, an embodiment capable of realizing such an operation will be specifically described. As shown in FIGS. 18 to 21, in this embodiment, when a lottery operation for the reversing operation of the speaker is performed (when such a control command is received), the SE is used to identify a series of sound effects. The Si command FFH is added to the head of the Si command string (FIGS. 18A and 19). Here, the Si command FFH is a command that means that the speaker position reverse lottery is performed when the subsequent Si command sequence is activated. Note that such a Si command is not added to the head of the BGM Si command string (FIG. 18B). The Si command FFH specifies sound NO = FFH (see FIG. 20), and the sound NO = FFH specifies data FFH instructing execution of the lottery (FIG. 21B). c)).

  FIG. 22 is a block diagram for explaining the configuration of the sound control board 3 according to the second embodiment. In this embodiment, an analog changeover switch SW is provided, and this analog changeover switch SW is controlled by a control signal SG from the output port 19 of the one-chip microcomputer 10. That is, if the control signal SG is at the H level, the analog signals DA0 and DA1 are supplied to the amplifiers 11R and 11L as in the first embodiment, whereas if the control signal SG is at the L level, the analog signals DA0 and DA1 are supplied. The transmission path of DA1 is reversed and supplied to the amplifiers 11L and 11R. The level of the control signal SG output from the output port 19 is determined by random lottery when the Si command FFH is interpreted and the sound NO (FFH) is extracted.

  FIG. 23 is a flowchart describing only the characteristic part of the operation of the second embodiment, and is a main routine corresponding to FIG. 6 of the first embodiment. Explaining below, if the sound NO is identified by the process of step ST9 and no error has occurred, it is first determined whether or not the sound NO is FFH (ST101). If the sound NO ≠ FFH, an H level control signal SG is output from the output port 19 to operate the speaker SP in a normal state (ST103).

  On the other hand, if the sound is NO = FFH, a lottery is performed as to whether or not the operation of the speaker is reversed. If the sound is won, an L level control signal SG is output from the output port 19 and analog switching is performed. The transmission path of the switch SW is switched. As a result, the subsequent BGM sound is supplied from the DA0 terminal of the D / A converter to the amplifier 11L and output from the left speaker SP, and the SE sound is supplied from the DA1 terminal of the D / A converter to the amplifier 11R. Are output from the speaker SP (speaker inversion operation).

FIG. 24 is a diagram for explaining the lottery operation. Step ST102 will be further described with reference to FIG. 24. The CPU that has determined that sound NO = FFH determines which control command is the audio information to be reproduced from now on in order to specify the reception buffer (FIG. 24 (a)), the control command indicated by the pointer RDLOT is read, and then the pointer RD Update the value of LOT. Next, the lottery table (FIG. 24 (b)) is searched using the read control command as a search key, and it is determined whether or not to perform the speaker reversal operation with an appropriate random value RND ′.

  The lottery table in FIG. 24B defines for each control command whether or not lottery for speaker reversal operation is performed, and determines a lottery value for performing lottery. For convenience, FIG. 23B shows the winning probability. For example, when using a random value RND ′ that changes in a numerical range from 0 to 99, if the received control command is A001H, If 0 ≦ RND ′ <10, the inversion operation is performed. If 10 ≦ RND ′ <100, the inversion operation is not performed.

  In this embodiment, when the winning state is finally reached, the winning probability of performing the reversing operation is increased (70% or more), whereas when finally becoming the lost state, the winning probability of performing the reversing operation is increased. It is low. In addition, only the control command for performing the symbol variation operation on the liquid crystal display 8 on the symbol control board (A0 **), the speaker inversion operation is selected, and in the case of other control commands, the speaker is always driven to normal. Yes. Therefore, it is possible for the player to focus on the liquid crystal display 8 and to infer how the current symbol variation will end depending on the position where the sound effect is emitted, thereby realizing a new gameplay. it can.

  Finally, a bullet ball game machine to which the present invention is preferably applied will be described for confirmation.
