Abstract

PROBLEM TO BE SOLVED: To improve a performance effect through improvement of sound quality by automatically and quantitatively determining sound that is likely to become unclear and preventing the output thereof, regardless of sound overlap timing and an overlap mode.SOLUTION: In a game machine, a sound selection means selects one or a plurality of sounds to be output from the plurality of sounds stored in a sound storage means according to the progress of a game. When the plurality of sounds are selected, a sound determination means compares a difference in sound pressure level corresponding to two arbitrary sounds among the plurality of sounds and a sound pressure threshold indicating the difference in the sound pressure level determined in advance for the combination of the kinds of the two arbitrary sounds, and determines whether to output one of the two arbitrary sounds. A sound output means outputs the sound determined to be output.

Description

  The present invention relates to a gaming machine that performs an effect with a story for each predetermined opportunity.

  In a slot machine as a gaming machine, a winning combination is drawn in accordance with the insertion of medals (game media) by a player and operation of a start switch, and a plurality of rotating reels with various symbols are rotated. Then, according to the lottery result and the player's operation of the stop switch, the rotating reels are sequentially stopped, and when the symbol combination corresponding to the winning combination is displayed on the active line that is the payout target line, a predetermined number The player will be given a gaming profit in accordance with the winning combination.

  In such a slot machine, an effect that gives a story to the game or suggests a lottery result of the winning combination is executed. As effects, various effects are displayed on the liquid crystal display unit, and various sounds are output from the speakers in an aspect corresponding to the images, thereby improving the effects.

  In recent years, with the diversification of images, the corresponding sounds have also been diversified, and it has become possible to give the player a sense of expectation for the lottery result of the winning role through the sound together with the various images. In order to maintain the effect, BGM (Back Ground Music) sound, effect sound, and the like are multiplexed and output. As described above, a technique is disclosed in which when the BGM sound and the effect sound overlap, a sound is generated by changing the volume of at least one of the sounds (for example, Patent Document 1). In addition, a technique for changing BGM sound when another effect sound is generated while BGM sound is generated at a predetermined volume is also known (for example, Patent Document 2).

Japanese Patent Laid-Open No. 2007-6986 JP 2005-152150 A

  However, with the diversification of voices, there are many cases where multiple voices are mixed while a game is in progress, and the voices that the player wants to listen to overlap with other voices unnecessarily, resulting in lack of clarity. On the other hand, there were cases where the effect of the voice was reduced.

  Therefore, in order to avoid such unnecessary superimposition of a plurality of sounds, it is necessary to change the program related to sound output. However, since each sound is superimposed in various modes as the game progresses, It has been difficult to specify the type of the program in advance and to strictly set which voice is to be programmed so as not to output it.

  In addition, it is difficult to grasp the result of such audio superimposition at the time of design, and in many cases it can be grasped only after actually outputting each sound in the slot machine, and depending on the superimposition result, redesign may be required. there were.

  Therefore, the present invention automatically and quantitatively determines the sound that may impair the clarity and avoids the output regardless of the timing at which the plurality of sounds overlap and the superposition mode thereof, and provides the effect of the production through the improvement of the sound quality. An object is to provide a gaming machine capable of improving the performance.

  In order to solve the above-described problems, the gaming machine of the present invention has a winning combination lottery means for determining either a winning combination or a loss by lottery based on an operation of a start switch, and a plurality of types of symbols are arranged. A plurality of rotating reels and a rotation reel corresponding to the operated stop switch based on the operation of the stop switch corresponding to the rotating rotating reel. Reel control means for controlling each stop, determination means for determining whether a symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed on the active line, and a symbol combination corresponding to the winning combination determined in the winning combination lottery Is displayed on the active line, a payout control means for paying out the game medium corresponding to the winning combination, and a plurality of sounds. In addition, one or a plurality of voice storage means that are stored in association with the sound pressure levels based on the sound pressure of the voice and a plurality of voices that are stored in the voice storage means according to the progress of the game. A combination of a sound pressure level difference corresponding to each of any two of the plurality of sounds and a type of any of the two sounds; Is compared with a sound pressure threshold value that indicates the magnitude of the difference in sound pressure level, and whether or not to output any one of the two sounds is determined according to the result. And a sound output means for outputting the sound determined to be output.

  The sound determination means does not output one of two arbitrary sounds when the sound pressure level of one sound is smaller than the sound pressure level of the other sound and the difference is equal to or greater than the sound pressure threshold. May be determined.

  The sound pressure level includes a predetermined average sound pressure level that is set based on an average value of sound pressures of the sound during each predetermined period for each predetermined period obtained by dividing the sound into a plurality of sound determination means. May take a difference by using a predetermined average sound pressure level as a sound pressure level for at least one of two arbitrary sounds.

  According to the present invention, regardless of the timing at which a plurality of sounds overlap and the superposition mode thereof, it is possible to automatically and quantitatively determine the sound that may impair the clarity and avoid the output thereof, and produce the effect through the improvement of the sound quality. Can be improved.

However, a backup power supply (not shown) is connected to the main RAM 200c, and even when the power is cut off, the data is retained without being erased unless the initialization process of the main RAM 200c is intentionally executed. .

  The main control board 200 functions by the main CPU 200a cooperating with the main RAM 200c based on the program stored in the main ROM 200b. The initialization means 300, the betting means 302, the winning combination lottery means 304, the reel control means. 306, a determination unit 308, a payout control unit 310, and a credit unit 312. The initialization unit 300 executes an initialization process in the main control board 200. The betting means 302 bets medals for use in games. The winning combination lottery means 304 determines either a winning combination or a loss by a lottery based on the betting of medals and the operation of the start switch 128 (winning combination lottery). The reel control means 306 controls rotation and stop of each rotary reel 134a, 134b, 134c. The determination means 308 determines whether or not the symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed on the active line. The payout control means 310 pays out a medal corresponding to the winning combination based on the fact that the symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed on the active line. The credit means 312 stores medals as credits.

  In the main control board 200, various detection signals are received from the inserted medal detection unit 124b, the bet button 126, the start switch 128, the stop switch 130, and the checkout button 132. Based on the received detection signals, the main CPU 200a has various types. Execute the process. Further, a main credit display unit 152 and a main payout display unit 154 are connected to the main control board 200, and the payout control unit 310 displays a medal credit number and a payout number on both display units 152 and 154. Control.

  In addition, a reel drive control unit 258 is connected to the main control board 200. The reel drive control unit 258 drives the stepping motor 262 based on the rotation start signal of each of the rotating reels 134a, 134b, 134c transmitted from the main control board 200 based on the operation signal of the start switch 128, and also uses the stop switch. The driving of the stepping motor 262 is stopped based on the stop signal of the left reel 134a, the middle reel 134b, and the right reel 134c and the detection signal of the rotational position detection circuit 260, which are transmitted from the main control board 200 based on the operation signal 130.

A detection signal from the payout medal detection unit 264c is input to the main control board 200, and the payout control unit 310 counts the number of medals to be paid out according to the detection signal, and outputs from the payout control unit 264b. Control the discharge of medals.

  The main control board 200 is provided with random number generating means 200d. The random number generating means 200d sequentially increments the count value, loops within a predetermined numerical range, and extracts the count value at a predetermined time point to obtain a random number. The random number generated by the random number generation means 200d is used to determine a gaming profit to be given to the player, for example, a winning combination (winning winning lottery random number).

(Table used in main control board 200)
In the slot machine 100, a plurality of game states are provided when the game progresses, and a plurality of winning combination lottery tables corresponding to these game states and set values are stored in the main ROM 200b. The winning combination lottery means 304 extracts the corresponding winning combination lottery table from the main ROM 200b in accordance with the current gaming state and set value stored in the main RAM 200c, and based on the extracted winning combination lottery table, the start switch 128. It is determined which winning combination lottery random number acquired in response to the operation signal corresponds to which winning combination or lose in the winning combination lottery table.

  Here, the winning combination extracted from each winning combination lottery table includes a replay combination, a small combination, and a bonus combination. The state in which the symbol combinations corresponding to such winning combinations are aligned on the active line is called display (winning), and the state until winning the winning combination and displaying the symbol combination corresponding to the winning combination is displayed internally. Winning status. Among the winning combinations, the replay combination is a combination in which one game can be executed again without placing a new bet of medals when the symbol combination corresponding to the replay combination is displayed on the active line. The combination of symbols corresponding to the small combination is displayed on the active line, whereby a predetermined number of medals can be paid out. The bonus combination is a winning combination that can shift the gaming state from the normal gaming state to the bonus gaming state by displaying the symbol combination corresponding to the bonus combination on the active line. Here, the bonus gaming state is a winning combination lottery table (a winning combination lottery table for bonus gaming state described later) in which a winning probability of a small combination is set so that medals substantially increase when determining a winning combination. This is a gaming state to be used, which means a gaming state that is more advantageous than the normal gaming state. In the following, the gaming benefits given to the winning combination and the player will be described.

  FIG. 5 is an explanatory diagram for explaining the effective line and each table. FIG. 5A shows an effective line in the present embodiment. Here, there are five effective lines. Specifically, among the nine symbols facing the symbol display window 136, the positions corresponding to the symbols that stop at the middle stage of the left reel 134a, middle reel 134b, and right reel 134c are connected. Line B, the upper stage of the left reel 134a, the middle stage of the middle reel 134b, the line B1 connecting the positions corresponding to the symbols stopped at the lower stage of the right reel 134c, the lower stage of the left reel 134a, the middle stage of the middle reel 134b, the right reel 134c The line B2 connecting the positions corresponding to the symbols that stop on the upper stage, the line C1 connecting the positions corresponding to the symbols that stop on the upper stage of the left reel 134a, the middle stage of the middle reel 134b, the upper reel, and the left reel 134a. The line C2 connecting the positions corresponding to the symbols to be stopped at the lower stage, the middle stage of the middle reel 134b, and the lower stage of the right reel 134c. Each is set as a valid line.

  Further, as shown in the symbol combination of FIG. 5B, in this embodiment, as a winning combination, “Replay”, “Bell”, “Watermelon”, “Big Bonus (hereinafter referred to as“ BB ”)”. , “Regular Bonus (hereinafter referred to as“ RB ”)” in total of five types of winning combinations are provided. Among these, the winning role “Replay” corresponds to the above-mentioned replay role, the winning role “Bell”, the winning role “Watermelon” corresponds to the above-mentioned small role, and the winning role “BB” and the winning role “RB” correspond to the above-mentioned bonus role. It corresponds to.

  If any winning combination is won, an internal winning flag corresponding to each winning combination is established (ON), and the left reel 134a, the middle reel 134b, the right reel according to the establishment status of the internal winning flag. Each stop control of 134c will be performed. At this time, if the winning combination “Bell” and the winning combination “Watermelon” have been won, but the symbol combination corresponding to these winning combinations could not be displayed on the active line in that one game, The internal winning flag is turned off at (in this embodiment, the symbol combination corresponding to the winning combination “bell” can always be displayed on the active line). That is, the right to win a small role is limited to the game only, and the right cannot be carried over to the next one game (hereinafter simply referred to as “next game”).

  On the other hand, when the winning combination “BB” or the winning combination “RB” is won, the BB internal winning flag or the RB internal winning flag is established (ON), and the BB internal winning flag or the RB internal winning flag is set. The game state changes to the internal / middle game state according to the establishment status, and the stop control of each of the left reel 134a, the middle reel 134b, and the right reel 134c is performed. At this time, if the symbol combination corresponding to the winning combination “BB” or the winning combination “RB” cannot be displayed on the active line, the BB internal winning flag or the RB internal winning flag is carried over to the next game as it is. Thus, in the game after the next time, it becomes possible to display the symbol combinations corresponding to the winning combination “BB” and the winning combination “RB” on the effective line.

  In addition, when the internal winning flag corresponding to the winning combination “Replay” that is the replaying role is established, the symbol combination corresponding to the winning role “Replaying” is displayed on the active line, and the next game can be played without requiring a medal. The internal winning flag is turned off after the processing necessary for performing the processing is performed.

  The normal gaming state winning combination lottery table shown in FIG. 5C is used when determining the winning combination lottery random number in the normal gaming state. Here, an area corresponding to the total number of winning lottery random numbers (65536) is divided into a plurality of winning areas (1 to 6), and for each winning area, the winning combination and the ratio of winning each of the plurality of winning areas The winning range value (numerical value) indicating the relative number is associated. For example, the winning area “1” is associated with the winning combination “Replay” and the winning range value “8978”. Since the winning combination lottery random numbers are provided from 0 to 65535, the probability that the winning combination “Replay” is won is 8978/65536. The same association is made for the other winning areas 2 to 6. The winning combination lottery means 304 sequentially acquires a winning range value from a plurality of winning areas in the winning combination lottery table for the normal gaming state, sequentially subtracts the winning range value from the winning combination lottery random number, and the subtraction value When is less than 0, the winning combination associated with the winning area at that time is used as the lottery result. The lottery procedure can be applied to other lotteries.

  The bonus game state winning combination lottery table shown in FIG. 5D determines the winning combination random number in the bonus gaming state set by winning the symbol combination corresponding to the winning combination “BB” or the winning combination “RB”. It is used when doing. According to the bonus game state winning combination lottery table, the bonus combination and the replay combination are not repeatedly won, and the winning probability of the winning combination “Bell” is determined as the normal gaming state winning combination lottery table (FIG. 5C). It is set higher than (see). Here, the winning combination lottery table has been described by giving the winning combination lottery table for the normal gaming state and the winning combination lottery table for the bonus gaming state. However, the winning combination lottery table is not limited to this, and is used in the gaming state during internal winning. Various winning combination lottery tables are used in accordance with the gaming state, such as an internal winning state winning combination lottery table.

(Sub-control board 202)
Returning to FIG. 4, the sub-control board 202, similar to the main control board 200, includes various semiconductor integrated circuits including a sub-CPU 202 a that is a central processing unit, a sub-ROM 202 b that stores programs, a sub-RAM 202 c that functions as a work area, and the like. In particular, the presentation is controlled based on a command from the main control board 200. Similarly to the main RAM 200c, a backup power source (not shown) is connected to the sub RAM 202c, and even when the power is turned off, data is retained without being erased. The sub-control board 202 is also provided with random number generation means 202d, like the main control board 200, and the random numbers generated by the random number generation means 202d are mainly used for determining the mode of production (production. Lottery random number).

  Further, the sub control board 202 functions by the sub CPU 202a cooperating with the sub RAM 202c based on the program stored in the sub ROM 202b. The initialization determining unit 330, the command receiving unit 332, the effect determining unit (sound selection) Means) 334 and voice determining means 336. The initialization determining unit 330 executes initialization processing in the sub control board 202. The command receiving means 332 receives commands from other control boards such as the main control board 200 and performs processing for the commands. The effect determining means 334 determines the effect to be provided to the player. Specifically, the effect determining means 334 uses the image data displayed on the liquid crystal display unit 138, the effect lamp 142, the reel backlight 144, the reel upper light 146, the sub credit display unit 156, the sub payout display unit 158, and the like. In addition to determining various data for the effect, the effect sound data output from the speaker 140 is selected (temporarily determined). The sound determination unit 336 determines whether or not to output the sound selected by the effect determination unit 334. The determined sound is output from the speaker 140 through the sound IC 202e described later.

  Here, the production is provided through the liquid crystal display unit 138, the speaker 140, the production lamp 142, the reel backlight 144, the reel upper light 146, the sub credit display unit 156, the sub payout display unit 158 and the like as the game progresses. It is a visual and auditory expression means that can give a story to the game and can suggest a lottery result of the winning combination with a more dynamic image. As an effect suggesting the lottery result of the winning combination, for example, if the player appropriately stops the left reel 134a, the middle reel 134b, and the right reel 134c, the symbol combination corresponding to the winning combination is not necessarily an effective line. When winning a winning combination (for example, winning “watermelon”) that cannot always be displayed above, a symbol corresponding to the winning combination is suggested before the player performs the stop operation. Some prompt the combination to be displayed on the active line. In addition, with regard to the bonus combination described above, the BB internal winning flag and the RB internal winning flag can be carried over over a plurality of games, so an effect suggesting the winning of the bonus combination is performed over a plurality of games, It is possible to increase the player's expectation by invalidating the player's operation input for a predetermined time in the game and performing a freeze process during which a specific effect is executed. In addition, even if none of the winning roles has been won, it is possible to make the player have a high dividend expectation through the production as if the player has been won, so that the player will not get bored. It becomes.

  However, an image including a still image and a moving image displayed on the liquid crystal display unit 138 has a huge data capacity and a processing load associated with the display, and therefore is separately controlled via the liquid crystal control board 204. The sound to be output to the speaker 140 is controlled through the sound IC 202e provided on the sub-control board 202.

  In the sound IC 202e, a plurality of sound data (data indicating sound) such as FM tone color data and ADPCM sound data can be stored in a storage area assigned to each access code (SAC: Simple Access Code). In the audio IC 202e of the present embodiment, the sound pressure levels are stored in association with the plurality of audio data (audio storage means). In addition, the audio IC 202e can receive a command indicating an access code from the sub CPU 202a, assign audio based on audio data specified by the access code to a track according to the command, and output the audio at an appropriate volume through the speaker 140. Yes (voice output means). Further, when a plurality of such access codes are designated, the audio IC 202e can also output a plurality of audio data corresponding to the plurality of access codes in a plurality of tracks in parallel. Next, an effect lottery table for executing effects will be described in detail.

(Table used in sub-control board 202)
FIG. 6 is a diagram for explaining the effect lottery table. The sub ROM 202b of the sub control board 202 is provided with a plurality of effect lottery tables corresponding to a plurality of winning combinations and loses. When either the winning combination or the loss is determined by the winning combination lottery on the main control board 200, an effect lottery table corresponding to the lottery result is determined. For example, when the lottery result of the winning combination lottery is the winning combination “watermelon”, the effect determining means 334 selects the winning combination as shown in FIG. 6 among the plurality of winning lottery tables corresponding to the plurality of winning combinations and losers. An effect lottery table corresponding to “watermelon” is determined.

  In the effect lottery table corresponding to the winning combination “watermelon” as shown in FIG. 6, for example, an area corresponding to the total number of effect lottery random numbers (65536) is divided into a plurality of winning areas (1 to 8). For each region, the winning range value, the image data to be displayed on the liquid crystal display unit 138, and the effect sound data related to the effect output from the speaker 140 are associated with each other. The effect determining means 334 compares the winning range values of the plurality of winning areas in the effect lottery table with the effect lottery random numbers, and derives a lottery result corresponding to the effect lottery random numbers. That is, a winning range value (here, “8192”) is sequentially obtained from a plurality of winning areas in the effect lottery table, and the winning range value is sequentially subtracted from the effect lottery random number generated by the random number generating means 202d. When the subtraction value is less than 0, the image data and the effect sound data associated with the winning area at that time are used as the lottery result.

  For example, when the effect lottery random number is “20000”, the effect determination means 334 first derives a subtraction value “11808” by subtracting the winning range value “8192” of the winning area 1 from the effect lottery random number. Since the subtraction value “11808” is equal to or greater than 0 (since it is not less than 0), the effect determining means 334 continues to determine the winning area 2 that is the next winning area of the winning area 1 from the subtracted effect lottery random number “11808”. The subtraction value “3616” is derived by subtracting the winning range value “8192”. Since the subtraction value “3616” is 0 or more, the effect determination means 334 subtracts the winning range value “8192” of the winning area 3 that is the winning area next to the winning area 2 from the subtracted effect lottery random number “3616”. The subtraction value “−4576” is derived. Here, since the subtraction value “−4576” is less than 0, the effect determining means 334 uses “image data 3” and “effect audio data 3” associated with the winning area 3 as the lottery result. Here, since the total number of production lottery random numbers is 65536, the winning probability of each winning area is 8192/65536. Here, although explanation is omitted, other effects are also determined through the effect lamp 142, the reel backlight 144, the reel upper light 146, the sub credit display unit 156, the sub payout display unit 158, and the like.

  An image based on the image data determined in this way is displayed on the liquid crystal display unit 138, and sound based on the effect sound data is output from the speaker 140 in conjunction therewith. The sound changes according to the display mode of the image and plays a role of enhancing the effect of rendering the image data. Specifically, when the effect sound data output in conjunction with the image data is selected by the effect determining means 334 and the output of the effect sound data is determined by the sound determining means 336, the determined effect sound is determined. An access code indicating data is transmitted to the voice IC 202e. Hereinafter, the setting of audio data in the audio IC 202e will be described in detail.

  FIG. 7 is an explanatory diagram for describing a track provided in the audio IC 202e. The audio IC 202e reads out audio data corresponding to each access code and assigns it to a track provided in the audio IC 202e itself. At this time, the audio IC 202e is provided with a plurality of tracks, and the audio data is assigned to one of the tracks. In the present embodiment, for example, as shown in FIG. 7, nine tracks are provided, and the type of sound assigned to each track is determined in advance. For example, system audio is assigned to track 1, BGM audio is assigned to track 2, production audio is assigned to tracks 3 to 7, and error audio is assigned to tracks 8 and 9.

  Explaining the types of voices described above, the system voice is an operating sound indicating that the operation of the bet button 126, the start switch 128, the stop button switches 130a, 130b, 130c, etc. has been accepted by the slot machine 100, or a medal. A confirmation sound that accompanies the progress of the game, such as a payout sound for confirming that the game has been issued. BGM sound is a background sound that is maintained in the background for a relatively long time. The effect sound is a sound uttered in conjunction with the effect, such as a sound based on the effect sound data determined based on the effect lottery table described above. The error sound is sound that is output together with the error image while an error occurs and the game is stopped.

  Further, the plurality of tracks in the audio IC 202e have the following characteristics. First, only one sound (audio data) can be assigned to the same track. Therefore, when a BGM sound is already assigned in the track 2, if a new BGM sound is to be assigned, the BGM sound is overwritten, and the BGM sound before being overwritten is deleted. On the other hand, all the sounds assigned to different tracks are output in parallel. Therefore, even if the system sound is assigned to track 1 when the BGM sound is assigned to track 2, all the sounds are output in parallel. Since such sound is independently determined as to whether or not to output the sound according to the progress of the game, any of a plurality of sound types (system sound, BGM sound, effect sound, error sound) It is difficult to predict when will be output. In addition, regarding the production sound and the error sound, the same type of sound may be output in parallel. In this way, even if the sound is assigned to the track so that the sounds are output at the same timing, all the sounds are output in parallel, so that the continuity of the sounds is maintained.

  By the way, in recent years, with the diversification of production, voices are also diversified, and a plurality of voices are often mixed while a game is in progress, and the voices may overlap uselessly. If a plurality of sounds overlap in this way, the clarity of the sound is lost, and on the contrary, the effect of the sound is reduced. However, since such voices are superimposed in various ways as the game progresses, the timing of the superposition and the type of the voice are specified in advance, and what kind of voice is programmed so as not to be output is strictly determined. It is difficult to set. Therefore, in the present embodiment, when a sound having a relatively high sound pressure and a sound having a relatively low sound pressure are mixed, it is assumed that a sound having a relatively low sound pressure is not output. Specifically, when a plurality of sounds are assigned to a track so that they are output at the same timing, among the plurality of sounds, the assignment of a sound with a relatively low sound pressure that may impair clarity is omitted. Therefore, the voice is not intentionally output, and the voice having a relatively high sound pressure is clearly output. By doing so, only one or a plurality of sounds having a relatively high sound pressure are output, and a sound having a relatively low sound pressure is not output, so that the clarity of the sound can be ensured. Here, the reason for not outputting a sound with a low sound pressure is that when a plurality of sounds are superimposed, a sound with a low sound pressure is difficult to hear in the first place compared to a sound with a high sound pressure. This is because even if a voice that is difficult to hear is not output, it does not affect the progress of the game.

  On the other hand, if it is determined whether or not the sound is output only with the magnitude of the sound pressure, even if both sound pressures are large and the values are approximate, one of the two sounds is detected. It will not be output, and output of audio will be restricted unnecessarily. Therefore, in this embodiment, as will be described later, it is assumed that there is play in the determination of the magnitude of the sound pressure, and that when the difference between the sound pressures of the two sounds is large, the sound having a low sound pressure is not output. If the difference between the two is small and the sound pressure is not so different, it is determined that both voices are clear and both voices are output.

  Here, a sound with a high sound pressure and a sound with a low sound pressure can be quantitatively determined by the relative difference between the sound pressures. Here, the sound pressure (dB) of each sound is directly converted into a numerical value as a sound pressure level and stored in association with each sound. Then, whether or not the target voice has a higher sound pressure than other voices is determined by referring to the sound pressure levels corresponding to the respective voices and comparing the sound pressure levels.

  However, the sound pressure (WAV master data) indicating each sound can be predicted to some extent, but the sound predicted from the sound data depends on the characteristics of the sound source, the position of the speaker 140, the distance between the speaker 140 and the player, and the like. In many cases, the sound pressure of the voice actually heard by the player is different. Therefore, in the present embodiment, the sound pressure level is set based on the sound pressure measured when the sound is output alone by the slot machine 100 in advance. In this way, it becomes possible to compare sounds more appropriately based on the sound pressure that the player actually listens to. Further, as will be described later, when a plurality of sounds are output in a superimposed manner, the sound can be appropriately output based on the sound pressure actually heard by the player from the beginning, so that the original sound data (WAV) It is possible to avoid a situation in which design is performed only by sound pressure predicted from the master data) and forced to redesign unlike the sound pressure of the actually output sound.

  Here, it is necessary to compare the sound pressure levels for all combinations of two sounds out of the plurality of sounds to be output, and determine which sound has a lower sound pressure level (comparison determination process). However, if the sound pressure level comparison / determination process is repeated until the combination of the plurality of sounds to be output has not changed, the processing load increases unnecessarily. In addition, since the comparison result does not change between the voices whose outputs have already been determined, the second comparison determination process is unnecessary. Therefore, in this embodiment, when a new voice is selected (when a combination of a plurality of output voices is changed), the voice determination unit 336 compares the new voice with another voice. Whether to output a new sound is determined according to the comparison result, and the comparison determination process is not performed at other timings. By doing so, it is possible to avoid unnecessary comparison determination processing when the combination of a plurality of sounds to be output has not changed, and to reduce the processing load.

  Specifically, when a sound is newly selected by the effect determining means 334 or the like, the sound determination unit 336 compares the sound pressure level of the sound with the sound pressure level of one or more already selected sounds. Then, it is determined whether or not to output the newly selected voice. Here, the newly selected voice is the newly selected voice, and one or more already selected voices to be compared are the already selected voices. The newly selected sound is sound that has been selected by the effect determining means 334 but has not yet been determined whether or not to be output, and has not been assigned to a track. On the other hand, the already selected sound is a sound that has been determined to be output in the past and has already been assigned to a track. In addition, the already selected sound includes sound that has been selected by the effect determining means 334 and output by the sound determining means 336 but has not yet been assigned to the track. The above-mentioned sound (system sound, BGM sound, effect sound, error sound) becomes a newly selected sound when selected by the effect determining means 334, and is further selected as an already selected sound after the output is determined by the sound determining means 336. Be treated.

  If the sound determination means 336 compares the sound pressure level of the newly selected sound with the sound pressure level of the already selected sound and determines that the sound pressure level of the newly selected sound is low, the sound determining means 336 does not output the newly selected sound. can do. However, as described above, if it is determined whether or not the output is simply performed based on the magnitude of the sound pressure level, the output of the sound is unnecessarily limited. Therefore, in this embodiment, a sound pressure threshold value indicating the magnitude of the difference between the sound pressure levels is provided, and the sound determination unit 336 compares the sound pressure level of the newly selected sound with the sound pressure level of the already selected sound, When the sound pressure level of the selected sound is smaller than the sound pressure level of the already selected sound and the difference (absolute value) is equal to or greater than the sound pressure threshold, it is determined not to output the newly selected sound. In this way, the newly selected voice is not only smaller than the already selected voice, but only when it is smaller than the sound pressure threshold, that is, the newly selected voice is relatively very small compared to the already selected voice. It is determined that the output is not performed only on

  Here, the sound pressure threshold value is a minimum value of the difference in sound pressure level for determining not to output a sound with a low sound pressure, and is represented by a predetermined positive value. However, the criterion for determining whether or not to output audio may differ depending on the combination of the two types of audio to be compared. For example, if the two types of sound to be compared are BGM sound and system sound, the sound pressure level of BGM sound is very large compared to the sound pressure level of system sound, and accordingly the system sound is difficult to hear, It should be determined that the system sound is not output only when there is no point in outputting the system sound (for example, when the difference is 50 dB or more). Also, if the two types of voices to be compared are production voices, if there is no significant difference in sound pressure level (for example, if the difference is less than 25 dB), any voice can be heard clearly. Production sound should also be output. Therefore, in the present embodiment, sound pressure threshold values corresponding to respective combinations of two types of audio to be compared (system audio, BGM audio, effect audio, error audio) are individually determined. For example, if the two types of audio to be compared are BGM audio and system audio, the sound pressure threshold is set to 50 dB, and if the production audio is between, the sound pressure threshold is set to 25 dB. Here, the sound pressure threshold 50 dB is a reasonable value that does not require a system sound having a low sound pressure relative to the BGM sound, and the sound pressure threshold 25 dB is not necessary for one sound having a low sound pressure between the production sounds. This is a reasonable value. By doing so, it is determined that the sound pressure level of one sound is not output when the sound pressure level of one sound is lower than 50 dB in comparison with the other, and the sound pressure of one sound is between the production sounds. When the level is smaller than 25 dB compared to the other, it is determined that no output is made. Here, for convenience of explanation, two combinations of the combination of the BGM sound and the system sound and the combination of the production sounds will be described, but the sound pressure threshold can be individually set by a combination of other sounds. Needless to say. Hereinafter, a specific operation of the sound determination unit 336 that determines whether or not to output a newly selected sound using the sound pressure threshold will be described.

  FIG. 8 is an explanatory diagram for explaining the operation of the voice determination unit 336. Here, as shown in FIG. 8, it is assumed that BGM sound is assigned to track 2. Further, it is assumed that the system sound as the newly selected sound is selected at time A. The sound determination means 336 determines whether or not the BGM sound as the already selected sound is assigned to the track 2 of the sound IC 202e, and if so, reads the sound pressure level of the BGM sound. Here, it is assumed that the sound pressure level of the BGM sound is 100 dB, and the sound pressure level of the system sound is 10 dB. The sound determination means 336 compares the sound pressure level 10 dB of the system sound with the sound pressure level 100 dB of the BGM sound. Here, the sound pressure level 10 dB of the system sound is lower than the sound pressure level 100 dB of the BGM sound, and the difference 90 dB between the sound pressure level 10 dB of the system sound and the sound pressure level 100 dB of the BGM sound is determined by the difference between the BGM sound and the system sound. Since the sound pressure threshold value corresponding to the combination of 50 dB or more is not greater than 50 dB, the sound determination unit 336 does not assign the system sound as the newly selected sound to the track, that is, outputs the system sound. Decide not to.

  Further, when the effect sound is selected as the newly selected sound at the time point B, the sound determination unit 336 determines whether or not the effect sound as the already selected sound is assigned to the tracks 3 to 7 of the sound IC 202e. Here, since no other effect sound is assigned, the sound determination means 336 transmits the access code of the effect sound to the sound IC 202e, and assigns the effect sound as the newly selected sound to the track 7, for example. In this way, the effect sound as the new selection sound is output, and the effect sound becomes the already selected sound.

  Subsequently, when a production sound is newly selected as a new selection sound at time C, the sound determination means 336 determines whether or not the production sound as the already selected sound is assigned to the tracks 3 to 7 of the sound IC 202e. If it is determined and assigned, the sound pressure level of the selected voice is read out. Here, it is assumed that the sound pressure level of the effect sound as the newly selected sound is 40 dB, and the sound pressure level of the effect sound as the already selected sound is 30 dB. The sound determination unit 336 compares the sound pressure level 40 dB of the effect sound as the newly selected sound with the sound pressure level 30 dB of the effect sound as the already selected sound. Here, since the sound pressure level 40 dB of the effect sound as the newly selected sound is larger than the sound pressure level 30 dB of the effect sound as the already selected sound, the condition that the sound is not output is “the sound pressure level is small and the difference is Since the former of the condition “is greater than or equal to the sound pressure threshold” is not satisfied, the sound determination means 336 does not compare the sound pressure threshold 25 dB corresponding to the combination of effect sounds and the access code of the effect sound is sent to the sound IC 202e. Is transmitted, for example, the production sound is assigned to the track 3. Therefore, both the newly selected voice and the already selected voice are output. At this time, if there are a plurality of selected voices, it is sufficient to compare the sound pressure level of the selected voice having the highest sound pressure level with the sound pressure level of the newly selected voice. Here, “largest” is determined for the following reason. That is, in order to determine that a newly selected voice is to be output, even if the newly selected voice has a large or small sound pressure level with respect to all of the plurality of already selected voices, the difference must be less than the sound pressure threshold. . Then, if the newly selected voice can be output in comparison with the selected voice having the most severe sound pressure level, the newly selected voice can be output to other selected voices. It is because it is determined. Therefore, comparison with a selected voice other than the selected voice having the highest sound pressure level can be omitted.

  As described above, when a plurality of sounds are assigned to a track so that they are output at the same timing, the assignment of a sound track with a low sound pressure is omitted, and a sound with a high sound pressure is clearly output. Can do.

  In the above, it is determined whether or not the newly selected sound is assigned to the track, that is, whether or not the newly selected sound is actually output. However, when the sound is superimposed, the sound pressure exceeds the sound pressure threshold and is small. Compared with the purpose of not outputting audio, the selected audio that has already been assigned to the track (with audio output) because the output of the newly selected audio with high sound pressure has been determined, When the sound has a lower sound pressure than the newly selected sound, it is desirable to cancel the output (hereinafter simply referred to as cancellation). For this reason, the sound determination means 336 compares the sound pressure level of the newly selected sound with the sound pressure level of the already selected sound, the sound pressure level of the already selected sound is smaller than the sound pressure level of the newly selected sound, and When the difference (absolute value) is equal to or greater than the sound pressure threshold, the output of the selected sound is cancelled. By doing this, when the newly selected voice whose output is newly determined is relatively large compared to the selected voice, the output of the selected voice is canceled and the newly selected voice having a high sound pressure is clearly displayed. Can be output. Hereinafter, the canceling operation of the voice determining unit 336 will be described.

  9 and 10 are explanatory diagrams for explaining another operation of the voice determining unit 336. FIG. When the effect sound is selected as the newly selected sound at the time point D, the sound determination unit 336 determines whether or not the effect sound as the already selected sound is assigned to the tracks 3 to 7 of the sound IC 202e. Here, since the selected sound is assigned to the track 3 and the track 7, the sound determination unit 336 reads the sound pressure level of the effect sound as the already selected sound assigned to the track 3 and the track 7. Here, it is assumed that the sound pressure level of the newly selected sound is 60 dB, the sound pressure level of the effect sound assigned to the track 3 is 40 dB, and the sound pressure level of the effect sound assigned to the track 7 is 30 dB. As described with reference to FIG. 8, the sound determination unit 336 is assigned to the track 3 having the highest sound pressure level among the sound pressure level 60 dB of the effect sound as the newly selected sound and the effect sound as the already selected sound. The sound pressure level 40 dB of the effected voice is compared. Here, since the sound pressure level 60 dB of the effect sound as the newly selected sound is larger than the sound pressure level 40 dB of the effect sound as the already selected sound, there is no comparison with the sound pressure threshold 25 dB corresponding to the combination of the effect sounds. The sound determining means 336 transmits the access code of the effect sound to the sound IC 202e, and assigns the effect sound to the track 5, for example.

  Furthermore, the sound determination unit 336 determines whether or not to cancel the output of the selected sound. In the above-described output determination of the newly selected voice, it is sufficient to compare only the voice with the highest sound pressure level among the selected voices, but here, all the target selected voices are compared.

  First, the sound determination unit 336 compares the sound pressure level 40 dB of the effect sound assigned to the track 3 as the already selected sound and the sound pressure level 60 dB of the effect sound as the newly selected sound. Here, the sound pressure level 40 dB of the effect sound assigned to the track 3 as the already selected sound is smaller than the sound pressure level 60 dB of the effect sound as the newly selected sound, but the difference 20 dB is a combination of the effect sounds. Since the sound pressure threshold value is less than 25 dB, the sound determination unit 336 maintains the output of the production sound assigned to the track 3 (the output is not canceled). Subsequently, the sound determination unit 336 compares the sound pressure level 30 dB of the effect sound assigned to the track 7 as the already selected sound and the sound pressure level 60 dB of the effect sound as the newly selected sound. Here, the sound pressure level 30 dB of the effect sound assigned to the track 7 as the already selected sound is smaller than the sound pressure level 60 dB of the effect sound as the newly selected sound, and the difference 30 dB is a combination of the effect sounds. Therefore, the sound determination unit 336 cancels the output of the effect sound assigned to the track 7. Specifically, the sound determination unit 336 transmits to the sound IC 202e information indicating that the effect sound access code assigned to the track 7 and the sound indicated by the access code are to be deleted. As shown, the output of the production sound is canceled from time D.

  Thus, even if the selected voice becomes a voice whose sound pressure is lower than that of the newly selected voice because the output of the newly selected voice having a high sound pressure is determined, the output of the voice having the low sound pressure is canceled. As a result, it is possible to clearly output a sound with a high sound pressure.

  By the way, the sound pressure of voice fluctuates with the passage of time. Therefore, if the sound pressure level of the sound is limited to one point in time, such as when the sound starts, the overall sound pressure of the sound is not reflected. Therefore, the sound pressure level of the present embodiment includes one overall average sound pressure level set based on the average value in the time direction of the entire sound pressure of the sound. The overall average sound pressure level is used as the sound pressure level. By doing so, it is possible to appropriately determine whether the sound pressure of the sound is high or low based on the overall sound pressure level.

  However, as can be understood by paying attention to the combination of the system sound and the BGM sound, the system sound having a low sound pressure represented by the operation sound of the bet button 126, the start switch 128, the stop button switches 130a, 130b, 130c, etc. On the other hand, the output time of BGM sound having a large sound pressure that can be output over a plurality of games tends to be longer. Therefore, the average value over the entire time of the sound pressure of the BGM sound that is expected to vary greatly with the passage of time is used as a criterion for determining whether or not sound output is possible when the BGM sound is a selected sound. If adopted uniformly, even if the actual sound pressure of the BGM sound that has already been output at the time when the system sound is selected, the average value is compared and the assignment of the system sound to the track is omitted. May occur.

  Therefore, in the present embodiment, as shown in FIG. 10, for example, the continuously flowing BGM sound is divided into a plurality of periods, and the sound pressure level is set to a predetermined period for each predetermined period. Including a predetermined average sound pressure level (100 dB, 80 dB, 90 dB, 110 dB in FIG. 10) set based on the average value of the sound pressures in the time direction, As the sound pressure level of the BGM sound as the already selected sound to be compared with the sound pressure level of the system sound (overall average sound pressure level), a predetermined average sound pressure level corresponding to a predetermined period including the time point A, here 100 dB Use. In this way, it is possible to determine whether to output the system sound based on the sound pressure level (predetermined average sound pressure level) of the BGM sound at the timing when the system sound is output. As a result, it is possible to perform a more appropriate determination than when the overall average sound pressure level is adopted. At this time, it is determined that the already selected voice is selected by the effect determining unit 334 and output by the effect determining unit 334, but if the selected audio is not yet assigned to the track, the predetermined voice at the head thereof is determined. By comparing the average sound pressure level, it is possible to perform appropriate determination in the same manner.

  Further, in the above-described embodiment, the sound pressure measured when the sound is output alone alone in advance by the slot machine 100 is shown in decibels as it is, but each sound pressure is represented by a numerical value between 0 and 100. Can also be shown. For example, when an audio of 50 dB to 105 dB is used in an arbitrary slot machine 100 and an audio of 60 to 125 dB is used in another slot machine 100, it is replaced with a range of 0 to 100 to correspond. Thus, by unifying the sound pressure level with a numerical value of 0 to 100 among the models, the program relating to the determination of the sound pressure level does not depend on the model of the slot machine 100, and it is not necessary to change the program. Thus, the design cost can be reduced.

(LCD control board 204)
Returning to FIG. 4, the liquid crystal control board 204 is connected to the sub control board 202, a liquid crystal CPU 204 a that is a central processing unit, a liquid crystal ROM 204 b that stores programs and image data, a liquid crystal RAM 204 c that functions as a work area, and image control. The liquid crystal display unit 138 is controlled by bidirectional communication with the sub-control board 202, which includes various semiconductor integrated circuits including a VRAM 204f that functions as a work area when performing the operation. In addition, the liquid crystal control board 204 includes an initialization unit 360, a command reception unit 362, and an effect execution unit 364 that function by the liquid crystal CPU 204a cooperating with the liquid crystal RAM 204c based on a program stored in the liquid crystal ROM 204b.

  The initialization unit 360 executes an initialization process on the liquid crystal control board 204. The command receiving means 362 receives a command (for example, an effect display command) from another control board such as the sub control board 202, and performs processing on the command. The effect execution means 364 displays various images on the liquid crystal display unit 138 based on the received command. For example, when the effect execution means 364 receives a command to display the image data determined by the effect determination means 334 based on the effect lottery table, the effect execution means 364 extracts the image data from the liquid crystal ROM 204b based on the command, and displays the liquid crystal display. An image based on the data is displayed on the liquid crystal display unit 138 every frame period (for example, 33 msec).

  Hereinafter, specific processing in the main control board 200 and the sub control board 202 will be described.

(Main processing of main control board 200)
FIG. 11 is a flowchart showing main processing of the main control board 200. Here, first, an outline of one game after initialization will be described along the main process of the main control board 200, and then the details of each process will be described.

(Step S100)
When the power of the slot machine 100 is turned on via the power switch and becomes energized, the initialization unit 300 executes an initialization process in preparation for the start of the game. The initialization unit 300 generates backup data at any time while the power is on, and holds the backup data in the main RAM 200c. Therefore, even if an unexpected power interruption occurs, it is possible to restore the state before the power interruption using the stored backup data in this initialization process. For example, even if an unexpected power interruption occurs while the rotating reels 134a, 134b, 134c are rotating, the rotating reels 134a, 134b, 134c are started again after the return operation. Therefore, in the initialization process, the main RAM 200c is basically not initialized (RAM clear), but information unrelated to medal payout, for example, information related to performance, is initialized as necessary. The initialization unit 300 confirms the connection status and operation status of various devices including the reel unit 134.

(Step S200)
Next, the betting means 302 accepts the insertion of a prescribed number of medals from the medal insertion unit 124, or accepts the operation of the betting button 126 in a situation where the prescribed number of credits or more are stored, and completes the betting of medals. To start waiting for the operation of the start switch 128. Further, the betting means 302 transmits a throwing command indicating that the operation has been performed to the sub-control board 202. When the operation of the start switch 128 is detected, the process proceeds to the next step S300.

(Step S300)
Next, the winning combination lottery means 304 acquires one winning combination lottery random number at the time when the start switch 128 is operated from the winning combination lottery random number updated by the random number generation means 200d in response to the operation of the start switch 128. To do. Then, the winning combination lottery means 304 selects one winning combination corresponding to the currently set gaming state from a plurality of winning combination lottery tables including the winning combination lottery tables shown in FIGS. 5 (c) and 5 (d). In addition to determining the winning lottery table, it is determined which winning area in the determined winning winning lottery table the acquired winning lottery random number corresponds to, and the winning combination or lose of the determined winning area is determined as the lottery result . In addition, after the lottery result is determined according to the operation of the start switch 128, the winning combination lottery means 304 receives a winning combination command including the lottery result (winning combination or lose) of the winning combination lottery, information on the gaming state, and the like. Transmit to the sub control board 202.

(Step S400)
When the lottery process is completed as described above, the reel control unit 306 next drives the stepping motor 262 to rotate the left reel 134a, the middle reel 134b, and the right reel 134c. In this reel rotation process, when a predetermined time (for example, 4.1 seconds) elapses from the start of rotation of the left reel 134a, middle reel 134b, and right reel 134c in the previous game (wait), the left reel in the game 134a, the middle reel 134b, and the right reel 134c start to rotate, and when the left reel 134a, the middle reel 134b, and the right reel 134c all rotate at a constant speed, the operation of the stop button switches 130a, 130b, and 130c is enabled. To do.

(Step S500)
Subsequently, when the reel control means 306 receives an operation of the stop button switches 130a, 130b, 130c by the player in a state where the stop button switches 130a, 130b, 130c are activated, the reel control unit 306 rotates the reel corresponding to the operation. (One of the left reel 134a, the middle reel 134b, and the right reel 134c) is stopped according to a predetermined stop control. Further, the reel control means 306, in response to the operation of the stop button switches 130a, 130b, 130c, each time a first stop command, a second stop command, and a third stop command indicating that the operation has been performed, The data is sequentially transmitted to the sub control board 202.

(Step S600)
Next, the determination unit 308 determines which of the predetermined combinations shown in FIG. 5B the symbol combination displayed on the active line shown in FIG. In accordance with the symbol combination, a process for determining the number of medals to be paid out, a game state changing process, and various processes required for replay are executed. Here, the determination means 308 is one of a plurality of gaming states having different degrees of advantage of the player based on the fact that the symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed on the active line. A gaming state, for example, a bonus gaming state is determined. In addition, the determination unit 308 sends a winning command including a symbol combination displayed on the active line and a payout command including a payout number of medals when a symbol combination corresponding to the small role is displayed on the effective line to the sub-control board 202. Send.

(Step S700)
Subsequently, on the basis of the determination result in step S600, for example, when the symbol combination corresponding to the small combination is displayed on the active line, the payout control unit 310 executes a medal payout process corresponding to the small combination, When the symbol combination corresponding to the replay combination is displayed on the active line, a process for automatically betting the next game is executed. In this way, the payout control means 310 performs various processes corresponding to the symbol combinations displayed on the active line, and ends the one game. Further, when the medal payout process is performed, the payout control unit 310 transmits a payout command indicating that the payout process has been performed to the sub-control board 202.

  As shown in steps S200 to S700, a game can be started through insertion of medals, and one game is executed through a series of processing from operation of the start switch 128 to payout by winning. Thereafter, steps S200 to S700 are repeated.

(Main processing of sub control board 202)
FIG. 12 is a flowchart showing the main process of the sub control board 202.

(Step S1100)
When the power of the slot machine 100 is turned on via the power switch and becomes energized, the initialization determining unit 330 of the sub control board 202 executes the initialization process, like the initialization unit 300 of the main control board 200, Allow. The initialization determining unit 330 generates backup data while the power is turned on, holds the backup data in the sub RAM 202c, and is held in this initialization process when an unexpected power failure occurs. Execute the process to return to the state before power-off using the backup data.

(Step S1200)
The command receiving unit 332 determines whether or not a command from the main control board 200 has been received, and maintains the command standby state by repeating the process of step S1200 while the command is not received. If it is determined that a command has been received, the command receiving unit 332 proceeds to step S1300.

(Step S1300)
If it is determined in step S1200 that a command has been received, the command receiving unit 332 executes various processes based on the received command.

(Detailed processing of command reception processing S1300)
FIG. 13 is a flowchart showing the command reception process in step S1300. Here, only processes related to the features of the present embodiment will be described in detail, and descriptions of configurations unrelated to the features of the present embodiment will be omitted.

(Step S1301)
First, the command receiving means 332 determines whether or not the received command is an input command. As a result, if the received command is the input command, the process proceeds to step S1302, and if it is not the input command, the process proceeds to step S1303.

(Step S1302)
If it is determined in step S1301 that the command received is the input command, the voice determination unit 336 determines whether to output the system voice based on the input command. The system audio output determination process S1302 will be described in detail with reference to FIG. Note that, as described above, this insertion command is a command transmitted in the betting process S200 of FIG. 11, and information indicating that the betting means 302 has been operated is added.

(Step S1303)
Next, the command receiving means 332 determines whether or not the received command is a winning combination command. As a result, if the received command is a winning combination command, the process proceeds to step S1304. If the received command is not a winning combination command, the process proceeds to step S1305.

(Step S1304)
If it is determined that the command received in step S1303 is a winning combination command, the effect determining unit 334 determines an effect to be provided to the player. The effect determination process S1304 will be described in detail with reference to FIG. Note that, as described above, this winning combination command is a command transmitted in the lottery process S300 of FIG. 11, and when any winning combination is won, information indicating the type of the winning combination is added. If any winning combination is not won, information indicating a loss is added.

(Step S1305)
Subsequently, the command receiving unit 332 determines whether the received command is any of the first to third stop commands. As a result, if the received command is one of the first to third stop commands, the process proceeds to step S1306, and if it is not any of the first to third stop commands, the process proceeds to step S1307.

(Step S1306)
If it is determined that the command received in step S1305 is one of the first to third stop commands, the voice determination unit 336 determines whether to output the system voice based on the first to third stop commands. decide. The system sound output determination process S1306 has the same process flow as the system sound output determination process S1302 described with reference to FIG. 14, and the input command is set to the first to third stop commands, the bet button 126 is set to the stop button switch 130a, Since it can be understood by replacing with 130b and 130c, detailed description thereof is omitted here. Note that, as described above, the first to third stop commands are commands transmitted in the reel stop processing S500 in FIG. 11, and it is confirmed that any one of the stop button switches 130a, 130b, and 130c has been operated. Information to indicate is added.

(Step S1307)
Next, the command receiving means 332 determines whether or not the received command is a winning command. As a result, if the received command is a winning command, the process proceeds to step S1308. If not, the process proceeds to step S1309.

(Step S1308)
If it is determined in step S1307 that the received command is a winning command, the effect determining means 334 determines whether to output BGM sound based on the winning command. The BGM audio output determination process S1308 will be described in detail with reference to FIG. Note that, as described above, this winning command is a command transmitted in the determination process S600 of FIG. 11, and the symbol combination displayed on the active line and the symbol combination corresponding to the small role are displayed on the active line. In this case, information indicating the number of medals paid out is added.

(Step S1309)
Subsequently, the command receiving unit 332 determines whether the received command is one of payout commands. As a result, if the received command is one of the payout commands, the process proceeds to step S1310. If not, the process proceeds to step S1311.

(Step S1310)
If it is determined in step S1309 that the received command is one of the payout commands, the voice determination unit 336 determines whether to output the system voice based on the payout command. The system sound output determination process S1310 has the same process flow as the system sound output determination process S1302 described with reference to FIG. 14, and replaces the insertion command with a payout command and the operation sound of the bet button 126 with a medal payout sound. Therefore, detailed description thereof is omitted here. Note that, as described above, this payout command is a command transmitted in the payout process S700 of FIG. 11, and information indicating that the payout process has been performed is added.

(Step S1311)
Next, the command receiving unit 332 performs various other processes for the received command (for example, a throw command, a winning combination command, first to third stop commands, a winning command, a payout command, etc.), for example, a liquid crystal display unit 138. Processing such as generating an image command for specifying an image to be displayed on the LCD and transmitting it to the liquid crystal control board 204 is performed, and the command reception processing S1300 is terminated. Since such processing is irrelevant to the features of the present embodiment, description thereof is omitted here.

  FIG. 14 is a flowchart showing the system audio output determination process in step S1302.

(Step S1302-1)
When the command receiving means 332 receives the input command, the sound determining means 336 determines whether or not BGM sound as the already selected sound is assigned to the track 2 of the sound IC 202e. As a result, when it is determined that the BGM sound is assigned, the process proceeds to step S1302-2, and when it is determined that the BGM sound is not assigned, the process proceeds to step S1302-4.

(Step S1302-2)
When it is determined in step S1302-1 that the BGM sound is assigned, the sound determination unit 336 determines from the sound pressure level of the system sound (operation sound of the bet button 126) based on the input command as the newly selected sound. A subtraction value is derived by subtracting the sound pressure level of the BGM sound as the already selected sound.

(Step S1302-3)
Subsequently, the sound determination unit 336 reads a sound pressure threshold value (for example, 50 dB) corresponding to the combination of the system sound and the BGM sound, and the subtraction value derived in step S1302-2 is negative (the sound pressure level of the system sound). Is smaller than the sound pressure level of the BGM sound), and it is determined whether or not the absolute value of the subtraction value is equal to or greater than the read sound pressure threshold. As a result, when it is determined that the subtraction value is negative and the absolute value is equal to or greater than the sound pressure threshold, the system sound output determination process S1302 is terminated without outputting the system sound based on the input command. If it is determined that the subtraction value is positive or the absolute value is less than the sound pressure threshold, the process proceeds to step S1302-4.

(Step S1302-4)
If it is determined in step S1302-1 that no BGM sound is assigned, or if it is determined in step S1302-3 that the subtraction value is positive or the absolute value is less than the sound pressure threshold value, The sound determination means 336 assigns the system sound based on the input command to a predetermined track (for example, track 1) of the sound IC 202e and determines to output the system sound. Thus, the system sound based on the input command is output through the speaker 140.

  FIG. 15 is a flowchart showing the effect determination process in step S1304.

(Step S1304-1)
When the command receiving means 332 receives the winning combination command, the sound determining means 336 determines whether or not BGM sound as the already selected sound is assigned to the track 2 of the sound IC 202e. As a result, when it is determined that the BGM sound is assigned, the process proceeds to step S1304-2, and when it is determined that the BGM sound is not assigned, the process proceeds to step S1304-4.

(Step S1304-2)
If it is determined in step S1304-1 that the BGM sound is assigned, the sound determination unit 336 determines from the sound pressure level of the system sound (operation sound of the start switch 128) based on the winning combination command as the newly selected sound. The subtraction value is derived by subtracting the sound pressure level of the BGM sound as the already selected sound.

(Step S1304-3)
Subsequently, the sound determination unit 336 reads a sound pressure threshold value (for example, 50 dB) corresponding to the combination of the system sound and the BGM sound, and the subtraction value derived in step S1304-2 is negative (the sound pressure level of the system sound). Is smaller than the sound pressure level of the BGM sound), and it is determined whether or not the absolute value of the subtraction value is equal to or greater than the read sound pressure threshold value. As a result, when it is determined that the subtraction value is negative and the absolute value is equal to or greater than the sound pressure threshold, the process proceeds to step S1304-5 without outputting the system sound based on the winning combination command. If it is determined that the subtraction value is positive or the absolute value is less than the sound pressure threshold, the process proceeds to step S1304-4.

(Step S1304-4)
If it is determined in step S1304-1 that no BGM sound is assigned, or if it is determined in step S1304-3 that the subtraction value is positive or its absolute value is less than the sound pressure threshold value, The sound determination unit 336 determines that the system sound based on the winning combination command is assigned to a predetermined track (for example, track 1) of the sound IC 202e and the system sound is output. Thus, the system sound based on the winning combination command is output through the speaker 140.

(Step S1304-5)
Then, in order to determine the effect based on the winning combination command, the effect determining means 334 selects one effect corresponding to the winning combination included as information in the winning combination command from the plurality of effect lottery tables stored in the sub ROM 202b. A lottery table (see, for example, FIG. 6) is determined.

(Step S1304-6)
Next, the effect determining means 334 acquires one effect lottery random number from the effect lottery random numbers updated by the random number generating means 202d.

(Step S1304-7)
Subsequently, the effect determination means 334 determines which winning area in the effect lottery table the effect lottery random number acquired in step S1304-6 corresponds to, and determines the image data of the determined winning area. Select audio data. Specifically, the effect determination means 334 sequentially refers to the winning range value from a plurality of winning areas in the effect lottery table according to a predetermined order (here, the order is indicated by the ordinal number attached to the winning area), When the winning range value is subtracted from the effect lottery random number and the subtraction value becomes less than 0, the effect associated with the winning area at that time is set as the lottery result. Further, although detailed description is omitted, various data for effects through the effect lamp 142, the reel backlight 144, the reel upper light 146, the sub credit display unit 156, the sub payout display unit 158, and the like are also determined.

(Step S1304-8)
The effect determining means 334 generates an effect display command based on the image data determined in step S1304-7 and transmits it to the liquid crystal control board 204.

(Step S1304-9)
Next, the sound determination means 336 determines whether or not the production sound as the already selected sound is assigned to the tracks 3 to 7 of the sound IC 202e. As a result, if it is determined that the production sound is assigned, the process proceeds to step S1304-11, and if it is determined that the production sound is not assigned, the process proceeds to step S1304-10.

(Step S1304-10)
If it is determined in step S1304-9 that the production sound is not assigned, the sound determination unit 336 uses the production sound data selected in step S1304-7 as a predetermined track (for example, tracks 3 to 3) of the sound IC 202e. 7), the output of the production sound is decided, and the production decision processing S1304 is ended. Thus, the production sound is output through the speaker 140.

(Step S1304-11)
When it is determined in step S1304-9 that the production sound is assigned, the sound determination unit 336 performs the sound pressure of the production sound based on the production sound data selected in step S1304-7 as the newly selected sound. The subtracted value is derived by subtracting the sound pressure level of the effect sound as the already selected sound from the level.

(Step S1304-12)
Subsequently, the sound determination unit 336 reads a sound pressure threshold value (for example, 25 dB) corresponding to the combination of effect sounds, and the subtraction value derived in step S1304-11 is negative (selected in step S1304-7). The sound pressure level of the effect sound based on the effect sound data is smaller than the sound pressure level of the effect sound as the already selected sound), and it is determined whether or not the absolute value of the subtraction value is equal to or greater than the read sound pressure threshold value. As a result, when it is determined that the subtraction value is negative and the absolute value is equal to or greater than the sound pressure threshold, the effect determination processing S1304 is terminated without outputting the effect sound, and the subtraction value is positive. Or when it determines with the absolute value being less than a sound-pressure threshold value, a process is transfered to step S1304-13.

(Step S1304-13)
If it is determined in step S1304-12 that the subtraction value is positive or the absolute value thereof is less than the sound pressure threshold, the sound determination unit 336 produces an effect based on the effect sound data selected in step S1304-7. The sound is assigned to a predetermined track (for example, any one of tracks 3 to 7) of the sound IC 202e, and it is determined to output the effect sound. Thus, the production sound is output through the speaker 140.

(Step S1304-14)
Subsequently, the sound determination means 336 determines that the subtraction value derived in step S1304-11 is positive (the sound pressure level of the effect sound as the already selected sound is based on the effect sound data selected in step S1304-7). It is determined whether or not the absolute value of the subtraction value is equal to or greater than the read sound pressure threshold value. As a result, if it is determined that the subtraction value is positive and the absolute value is greater than or equal to the sound pressure threshold, the process proceeds to step S1304-15, where the subtraction value is positive or the absolute value is sound pressure. When it determines with it being less than a threshold value, the said effect determination process S1304 is complete | finished.

(Step S1304-15)
If it is determined in step S1304-14 that the subtraction value is positive and the absolute value is greater than or equal to the sound pressure threshold, the voice determination unit 336 has a positive subtraction value and the absolute value is The output of the production sound as the already selected sound of the target that is equal to or higher than the sound pressure threshold is canceled. In this way, the output of the selected voice is cut off. Here, when there are a plurality of effect sounds as already selected sounds to be compared, the processing from step S1304-14 is repeated by that number.

  FIG. 16 is a flowchart showing the BGM audio output determination process in step S1308.

(Step S1308-1)
When the command receiving means 332 receives the winning command, the effect determining means 334 indicates that the symbol combination displayed on the active line indicated by the winning command is a symbol combination corresponding to a predetermined winning combination, for example, a bonus combination. Judge whether there is. As a result, if the symbol combination corresponds to the bonus combination, the process proceeds to step S1308-2. If the symbol combination does not correspond to the bonus combination, the BGM audio output determination process S1308 ends.

(Step S1308-2)
The effect determining means 334 determines one BGM audio lottery table corresponding to the symbol combination (bonus combination) displayed on the active line from a plurality of BGM audio lottery tables (not shown) stored in the sub ROM 202b. .

(Step S1308-3)
Next, the effect determining means 334 acquires one effect lottery random number from the effect lottery random numbers updated by the random number generating means 202d.

(Step S1308-4)
Subsequently, the effect determination means 334 determines which winning area in the BGM audio lottery table corresponds to the effect lottery random number acquired in step S1308-3, and selects the BGM audio data of the determined winning area as the lottery result. Determine as.

  As described above, with the slot machine 100 described above, regardless of the timing at which a plurality of sounds overlap and the manner of superimposing them, it is possible to determine and output the sound that may impair the clarity and improve the production effect through the improvement of the sound quality of the sound. Can be achieved.

  Further, since the slot machine 100 automatically and quantitatively determines the sound having a high sound pressure and the sound having a low sound pressure based on the actually measured sound pressure, The operation of predicting the type and embedding it in the program becomes unnecessary, and unnecessary work such as redesign can be avoided and the design cost can be reduced.

  Furthermore, since it is quantitatively determined whether or not to output the sound at the time of outputting the sound, it is not necessary to consider in advance whether or not the sound is easy to hear. It is possible to realize a design with a high degree of freedom without deeply considering the above.

  In addition, as a result, a sound that may impair the clarity is not output, so that power consumption can be reduced.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Is done.

  For example, in the above-described embodiment, it is assumed that the sound with a low sound pressure is not assigned to the track of the sound IC 202e. However, the sound volume of the track corresponds to 0 or 0 after being assigned to the sound IC 202e. The same purpose can be achieved by setting a very small value.

  Further, in the above-described embodiment, the sound having a low sound pressure level is not output based on the sound pressure levels of the two sounds to be compared, but whether to output in advance according to the combination of the two sounds. A voice to be determined may be determined. For example, in the above-described example of BGM sound and system sound, it can be assumed that the system sound is smaller than the BGM sound. Therefore, the sound determination unit 336 determines the sound pressure level of the system sound and the sound pressure level of the BGM sound. Even if the difference is derived without judging the magnitude, and it exceeds the sound pressure threshold (for example, 50 dB) corresponding to the combination of the system sound and the BGM sound, the system sound may not be forcibly output. Good.

  In the above-described embodiment, the same sound pressure threshold is used for both the case where it is determined not to output the newly selected sound and the case where it is determined that the output of the already selected sound is cancelled. Not only the case but also the threshold values used for both determinations can be made different.

  In the above-described embodiment, when the difference between the sound pressure levels of the sound exceeds the sound pressure threshold, it is not assigned to the track. However, the sound is temporarily assigned by assigning to the track and reducing the volume as described above. May be output and output determination may be performed again after the output of the selected audio to be compared is completed. In this case, when the difference between the sound pressure levels is less than the sound pressure threshold in the new output determination, the sound with the increased sound pressure can be output from the middle by setting the sound volume to an appropriate value.

  Further, in the above-described embodiment, whether or not to output sound is determined according to the sound pressure level or the sound output is canceled, but the sound that the player wants to listen to is surely excluded from the determination target. You can also In this case, it can be realized by associating such sound with a value equal to or higher than the upper limit of the sound pressure level, for example, 200 dB (101 or the like in the replaced value). With this configuration, for example, the player can intentionally increase the sound pressure level of the voice that the designer wants the player to listen to, the voice that the player needs to grasp the gaming state, winning combination, etc. Can be heard reliably.

  In the above-described embodiment, the sound pressure level includes one overall average sound pressure level that is set based on the average value of the sound pressure of the sound, and a predetermined time period that is predetermined. Although the case where the predetermined average sound pressure level set based on the average value of the sound pressure of the sound in each period is included has been individually described, both pieces of information may be included in the sound pressure level.

  In the embodiment described above, any two sounds are compared, and if the difference between the sound pressure levels is equal to or greater than the sound pressure threshold, the sound having a large sound pressure level is output (or the output is maintained), The sound with a low sound pressure level is not output (or the output is canceled). However, the present invention is not limited to this, and if the difference between the sound pressure levels is equal to or greater than the sound pressure threshold, the sound with the low sound pressure level is output ( Alternatively, the output may be maintained), and the sound having a high sound pressure level may not be output (or the output is canceled). By doing so, for example, it is possible to clarify a sound with a low sound pressure level that is difficult to hear when a plurality of sounds overlap, and allow the player to listen to it.

 Further, in the above-described embodiment, whether or not to output sound is determined according to the sound pressure level, or the sound output is canceled, but the sound that the player wants to listen to reliably and the progress of the game , The priority (importance level) of the audio to be compared, such as the audio necessary for the player to grasp the game status and winning role (audio that may miss gaming profits if not heard) It is also possible to determine not to output a relatively low priority audio.

  Specifically, when a high priority sound is a BGM sound and a low priority sound is a system sound, the difference in sound pressure level between these BGM sound and system sound exceeds a predetermined threshold. If so, the production sound with low priority is not output uniformly. In short, when the priority is set for the sound to be output, the sound determination means 336 determines which sound is output regardless of the volume level if the difference in sound pressure level of the output sound exceeds the threshold. It may be determined whether the priority is higher, leaving the voice with the higher priority, and not outputting the voice with the lower priority (ie, prohibiting the output).

  With such a configuration, if the sound pressure level is higher for a voice with a higher priority (BGM voice in the above example) than for a voice with a lower priority (system voice in the above example), Therefore, it is possible to clearly hear the high-priority sound because the high-priority sound that the user wants to listen to is not mixed with the low-priority sound.

  On the other hand, when the sound pressure level of the higher priority sound is lower than that of the lower priority sound, the high priority sound is prevented from being obscured by the lower priority sound. Can do.

  Note that the above-described audio priority level is determined according to the type of audio to be output (system audio, BGM audio, effect audio, error audio) as illustrated in the example of BGM audio and system audio. However, the present invention is not limited to this. For example, the priority of the newly selected voice is set higher than the priority of the already selected voice. Needless to say, the priority order can be appropriately set for the sound to be output, such as determining the priority order.

  Further, the processes performed by the main control board 200 and the sub control board 202 described above do not necessarily have to be processed in time series in the order described in the flowchart, and may include processes in parallel or by a subroutine.
